Nukleator (6) pod velikim pritiskom brizga v prostor za atomiziranje majhne količine vode, ki ustvarjajo vodno meglico (6.2), ki je ozko usmerjen curek, kateri se na minimalni razdalji (a je večji ali enak od 1,3) metra pomeša z vodnimi kapljicami (5.1) iz vodnih šob (5). Mešanje je omogočeno zaradi tega, ker lopatice ventilatorja (2) ustvarijo zadosti močan vrtinčast zračni tok (4.1.1), ki se komaj v točki (4.1.1.1) pomeša z vodo (5.1) iz šob (5) inledeno vodno meglico (6.2) iz nukleatorja (6) in tako se pomeša v točki (4.1.1.1) na ledeni ovoj, ki se naredi okoli podhlajenih vodnih kapljic (6.2), ki priteče iz nukleatorja (6) z vodo (5.1), ter se v nadaljevanju zračnega toka (A) le-ta pretvori v umetni sneg (7).The present invention relates to a new product designed as an artificial snowmaking device - a snow cannon, consisting of individual components and assemblies embedded in a snow cannon housing (1) into which a special snow cannon electric motor (3) is mounted in the central part, after which, in the direction of air flow (A), a nucleator (6) is positioned centrally, immediately behind the tip of the aerodynamic shape of the stator of the electric motor (3) and at the outlet of the air stream (A), one live annular segments are mounted in the round coil ( 5.0.2), with water nozzles (5). The high-pressure nucleus (6) is injected into the space to atomize a small amount of water, creating a water mist (6.2), which is a narrowly directed jet mixed with water at a minimum distance (but greater than or equal to 1.3) drops (5.1) from water nozzles (5). Mixing is made possible because the fan blades (2) produce a sufficiently strong swirling air flow (4.1.1) which is barely mixed with water (5.1) from nozzles (5) and a water mist (6.2) in point (4.1.1.1). ) from the nucleator (6) and thus mixed in point (4.1.1.1) on an ice pack made around the subcooled water droplets (6.2) flowing from the nucleator (6) with water (5.1) and subsequently in the air stream (A) turns it into artificial snow (7).
Description
Naprava za umetni snegArtificial snow machine
Naprave za izdelavo umetnega snega — snežni topovi se niso od njihove iznajdbe bistveno spreminjale glede na stanje tehnike, kot je bilo v startu postavljeno, in sicer na vrteči del rotor je umeščen močan ventilator in stoječi del - stator, ki je kot celota z ohišjem snežnega topa oblikovan kot votlo valjasto telo, skozi katerega prisilno pospešujemo pretok zraka. Pri prehodu zraka iz plinastega stanja na vhodu ventilatoija se le-ta turbulenci in na izhodu pobere vodne kapljice ter tako na izhodu iz naprave ustvarja umetni sneg. Da bi le-ta nastal, je potrebno zagotoviti ustrezno okolje ali delovati pri dovolj nizki temperaturi okolja, ki je primemo za izdelavo snežink, nastalih z izpihovanjem mrzlega zraka pomešanega s kapljicami vode. Če je ta postopek kapacitetno in tehnično koncipiran ter deluje v primernem okolju, lahko izdelujemo umetni sneg in pozimi zasnežujemo odprte prostore, ki so primerni za zimske športe. V zaprtih prostorih pa je postopek podoben, vendar moramo doseči dovolj nizke temperature površin, na katere pada umetni sneg in za to uporabljamo še dodatno tehniko ohlajanja tla in prostora (objekta) kot takšnega.Artificial snow machines - snow cannons have not changed significantly since their invention according to the state of the art, as it was initially set up, namely a powerful fan and a standing part mounted on the rotating part of the rotor, which is a whole with a snow casing the cannon is shaped like a hollow cylindrical body through which we forcibly accelerate the flow of air. During the passage of air from the gaseous state at the inlet of the ventilation, this turbulence and water droplets are collected at the outlet, thus creating artificial snow at the outlet of the device. In order to produce it, it is necessary to ensure an adequate environment or to operate at a sufficiently low ambient temperature, which is suitable for the production of snowflakes created by blowing cold air mixed with water droplets. If this process is capacitive and technically conceived and operates in a suitable environment, artificial snow can be made and snow covered in winter open spaces suitable for winter sports. Indoors, however, the process is similar, but we need to reach sufficiently low temperatures of the surfaces on which artificial snow falls, and for this we use the additional technique of cooling the soil and space (object) as such.
Drugi bistven tehnični pokazatelj za uspešno uporabo snežnega topa kot naprave za izdelavo umetnega snega je v tem, da zagotovimo zadostni pritisk vode in zraka kot medija za izdelavo snega, a to izvedemo s prisilnim potiskom vode v napravo in kompresorskim dovajanjem zraka. Izhajajoč iz navedenega poznamo visokotlačne in nizkotlačne tehnične rešitve in izvedenke naprav za izdelavo umetnega snega.Another essential technical indicator for the successful use of a snow cannon as a device for making artificial snow is to provide sufficient pressure of water and air as a medium for making snow, but this is done by forcing water into the device and compressor air supply. Based on the above, we know high-pressure and low-pressure technical solutions and versions of artificial snowmaking devices.
Pri visokotlačnih napravah za izdelavo umetnega snega, se zrak in voda mešata v notranjosti topa. V bistvu je to lavalova šoba, kjer komprimiran zrak pod tlakom med 4 in 8 barov mešamo z vodo in ta komprimiran zrak je obenem procesni zrak, ter aktivator kristalizacijskih kali. V šobi se mešanica zraka in vode popolnoma razbije pod vplivom zvočnih udarov, nato pa zaradi ekspanzije sunkovito zapusti šobo. Komprimiran zrak zagotavlja tudi domet topa. Slabosti tega sistema so oglušujoči hrup in enormna poraba energije. Dobra lastnost je zmožnost izdelave snega pri višjih temperaturah, saj se mešanica podhladi ob ekspanziji. Ti topovi se le še pogojno uporabljajo.In high-pressure artificial snowmaking installations, air and water are mixed inside the cannon. In fact, it is a lava nozzle where compressed air between 4 and 8 bars is mixed with water and this compressed air is both process air and an activator of crystallization tides. In the nozzle, the mixture of air and water completely breaks down under the influence of sound shocks, and then it leaves the nozzle for expansion. Compressed air also provides range for the cannon. The disadvantages of this system are deafening noise and enormous power consumption. A good feature is the ability to produce snow at higher temperatures as the mixture cools down upon expansion. These cannons are only conditionally used.
Nizkotlačni snežni topovi so taki, kjer komprimiran zrak skrbi le za kristalizacijska zrnca, ni pa potisni medij. Ti topovi se delijo na „žirafe”, kijih bomo v nadaljevanju teksta podrobneje opisali in propelerske topove, v katero skupino štejemo tudi našo inovativno rešitev podano v pričujoči patentni prijavi.Low-pressure snow cannons are those where compressed air only cares for the crystallization granules, but not the thrust medium. These cannons are divided into "giraffes", which will be described in more detail below, and propeller cannons, to which group we also include our innovative solution given in this patent application.
Takšna koncepcija proizvodnje umetnega snega in stanje tehnike vlada še danes s tem, da smo ljudje, predvsem pa razvojniki na področju fluidne tehnike, ti dve bistveni komponenti zrak in voda, ki sta pomembna za izdelavo umetnega snega, posodobili in tehnično izboljšali do taksne mere, da danes najdemo veliko posameznih izvedenk različnih tehničnih rešitev zasneževanja prostorov z napravami za izdelavo umetnega snega.This conception of artificial snow production and the state of the art is still ruled by the fact that humans, and especially developers in the field of fluid technology, have modernized and technically improved these two essential components of air and water, which are important for artificial snow production, that today we find many individual versions of different technical solutions for snowmaking with artificial snowmaking equipment.
V tem kontekstu poznamo različne sisteme, ki so našli široko uporabo predvsem na odprtih prostorih, ki so hkrati smučišča namenjena za vse oblike zimskih športov. Tako poznamo naprave za izdelavo umetnega snega, ki so v obliki podolgovatih palic, vrtečih se ali fiksno postavljenih v prostor, ki imajo vsaj eno vodno šobo, skozi katero se dovaja voda pod pritiskom. Tehniko so razvili različne iztočne sisteme, kot so: iztok vode skozi šobo s tem, da je zrak doveden skupaj z vodo; iztok vode skozi šobo, a zrak se dovaja okoli iztočne šobe, postavljeno večje število šob v zaporedje po eni premici ali več, z dovajanjem zraka po obeh ze navedenih sistemih. Torej paličasti, ki ga imenujemo tudi „ žirafe ” sistem, je že razvit v ducat različnih tehničnih izvedenk, ki so primerne za posamezne terene in površine, katere se zasnežuje. Pn„žirafah” se vodne šobe dvigne čim višje od tal, nato pa se iz njih brizgne voda.In this context, we know of a variety of systems that have found widespread use primarily in open spaces, which are also ski slopes for all forms of winter sports. Thus, we know artificial snowmaking devices which are in the form of elongated rods, rotating or fixedly placed in a room, which have at least one water nozzle through which water is pressurized. Various exhaust systems have been developed in the technique, such as: the flow of water through the nozzle by bringing the air together with water; the flow of water through the nozzle, but air is supplied around the nozzle, a plurality of nozzles arranged in a row or in a row, by supplying air through both systems already mentioned. So the rod, also known as the "giraffe" system, has already been developed into a dozen different technical designs that are suitable for individual terrains and snow-covered surfaces. During the giraffes, the water nozzles are raised as high as possible from the ground, and then water is sprayed from them.
V tem sistemu omogoča domet sama višina nosilne noge in dolžine izhodnega vrata, v katerem so vstavljene vodne šobe . Tudi ti topovi imajo atomizerje, ki vpihavajo ledena zrnca v osnovni curek in na tak način delajo sneg.In this system, the height of the supporting leg and the length of the exit door in which the water nozzles are inserted allow the range. Also, these cannons have atomizers that blow ice beads into the base jet and thus make snow.
Druga tehnična izvedenka zasneževanja je ta, da je vgrajenih eno ali več cevi po celotni dolžini terena oz. po tistem delu terena, ki je primeren in ga je potrebno umetno zasneževati, na cevi katere so v določenem razmiku zmontirane izhodne šobe, skozi katere se z velikim pritiskom potiska voda v prostor, kjer se podhlajena pretvarja v umetni sneg. Ta sistem je primeren takrat, ko imamo predvsem dovolj močne kompresorske naprave in neomejen vir vode ter zelo nizke temperature okolja.Another technical embodiment of snowmaking is that one or more pipes are installed along the entire length of the terrain or. after the part of the terrain that is suitable and which needs to be artificially snowed, on the pipes of which the outlet nozzles are mounted at a certain distance, through which the water is pushed with great pressure into the space where the cooled turns into artificial snow. This system is suitable when we have above all strong enough compressor devices and an unlimited source of water and very low ambient temperatures.
Obstajajo tudi enocevni ali večcevni sistemi, ki so na terenu postavljeni vertikalno, na katere so na določeni višinski razdalji vgrajeni snopi šob, skozi katere izhaja mešanica vode in zraka ter se tako ustvarja vodna meglica, ki se potem pretvarja v umetni sneg.There are also one-pipe or multi-pipe systems mounted vertically in the field, to which at a certain height there are bundles of nozzles through which a mixture of water and air flows, creating a water mist, which then turns into artificial snow.
Slabost vseh navedenih sistemov je v tem, da se dobršen del, tudi do 30 %, vode izgubi v obliki žleda, ki se na tleh kopiči kot led ter gledano po časovni premici zaledeni tudi samo napravo, kar povzroča dodatne skrbi in stroške upravljavcu teh sistemov.The disadvantage of all these systems is that a good part, even up to 30%, of water is lost in the form of ice, which accumulates on the ground as ice and, in terms of time, the device itself is frozen, which creates additional concerns and costs for the operator of these systems. .
Najbolj razširjena tehnična rešitev je ta, da se uporabi okrogel votel sistem, v katerega je umeščen motor - ventilator kot posamezna naprava z dodatnim kompresorjem in vodno črpalko, ki je v funkciji ustvarjanja velikih potisnih sil za vodo, ki je osrednji medij za izdelavo umetnega snega. Temu rečemo, da so to nizkotlačni propelerski snežni topovi, kjer komprimiran zrak skrbi le za kristalizacijska zrnca, ni pa potisni medij. Pri propelerskih topovih je potisni medij zunanji zrak, ki ga enakotlačni puhalniki-ventilatorski propelerji pospešijo mimo šob, kjer se vbrizgava vodna megla. Tik ob šobah so nukleatorji, iz katerih piha mešanica komprimiranega zraka in mala količina vode. Ko ta mešanica pride iz šobe hipno zamrzne in kadar ta ledena zrnca pridejo v osnovni curek vode in zraka, se pomešajo z vodnimi kapljicami, ki se pričnejo nabirat okrog njih kot snežinka.The most widespread technical solution is to use a circular hollow system incorporating a fan motor as an individual device with an additional compressor and a water pump, which is a function of generating large water thrust, which is the central medium for artificial snow production. . This is to say that these are low-pressure propeller snow cannons, where compressed air only cares for the crystallization granules, but not the thrust medium. For propeller guns, the thrust medium is ambient air, which is accelerated by the same pressure blower-fan propellers past the nozzles where water mist is injected. Next to the nozzles are nucleators from which a mixture of compressed air and a small amount of water blows. When this mixture comes out of the nozzle, it freezes and when these ice granules enter the basic jet of water and air, they are mixed with water droplets that begin to accumulate around them like a snowflake.
Predloženi izum se nanaša na nov proizvod za izdelavo umetnega snega - snežni top, v katerem je spremenjen sistem dovajanja komprimiranega zraka in vode in njunega sistema mešanja, koncipiran v predloženi inačici patentne prijave kot propelerski ventilator, vgrajen v notranjost ohišja snežnega topa, sestavljen iz zelo močnega elektromotorja, ki je posebej konstrukcijsko ter oblikovno koncipiran po tehnični rešitvi, podani v tej patentni prijavi.The present invention relates to a new artificial snow product - snow cannon, in which the system of supply of compressed air and water and their mixing system, conceptualized in the present patent application version, as a propeller fan, built into the interior of a snow cannon housing a powerful electric motor, which is specifically designed and designed according to the technical solution given in this patent application.
Druga bistvena inovativna rešitev po pričujoči patentni prijavi je v koncepciji nukleatorja, ki je umeščen tik za stožčasto obliko izhodnega dela statoija motoija, na katerega je zmontiran propelerski ventilator. Skozi nukleator se dovaja konstantna majhna količina ozko usmerjene vodnih - ledenih zrnc meglice v osnovni curek vodnih kapljic, ki jih dobimo in dovajamo iz izhodnih vodnih šob.Another essential innovative solution according to the present patent application is in the concept of a nucleator, which is positioned just behind the conical shape of the output part of the moto statue to which the propeller fan is mounted. A constant small amount of narrowly directed water - ice granules of mist is fed through the nucleator into the base jet of water droplets that are obtained and fed from the outlet water nozzles.
Tretja tehnična rešitev, ki zaokroža našo inovacijo, se kaže v razmestitvi izhodnih vodnih šob, ki omogoča neprekrivanje izhodnega curka vode in enakomerno dovajanje pritiska zraka na ustje sleherne šobe in s tem kontinuiranega zračnega rezanja vodnega curka na samem ustju šobe. To dosežemo tako, da smo konstrukcijsko in koncepcijsko spremenili stator motorja v aerodinamično kupolasto obliko, njegovo vpetje v ohišje z dvema ali več zobatimi lopaticami, ki imata/jo nalogo ustvaijanja maksimalnega vrtinčenja zračnih tokov, ki ustvarjajo prazen zračni prostor med izhodom vodnih curkov iz šob te ustvarjene vodne meglice iz nukleatorja. Na izhodu vodnih tokov smo konstrukcijsko umestili segmentno povečanje števila vodnih šob. Koncipirali smo najmanj en segment v obliki obroča na katerem so zmontirane vodne šobe. Vsak segmentni obroč se krmili posebej in je s tem omogočeno optimalno dovajanje vode ter navsezadnje prilagajanje količine le-te obstoječim vremenskim pogojema. Na izvedbenem primeru, v nadaljevanju prikazanem na skicah smo uporabili štiri segmentna obroča, vendar je le-teh lahko 1 + n, ki so gledano v smeri izhoda zraka in vode postavljeni v obliki lijaka, z malim kotom a. S tem smo omogočili maksimalno odrezovanje curka na izhodu iz šobe, ki je bistveno za neustvarjanje leda v predelu segmentnih obročev.The third technical solution that rounds off our innovation is the arrangement of the outlet water nozzles, which allows the outlet of a jet of water to be uninterrupted and the air pressure is uniformly applied to the mouth of each nozzle and thus the continuous air cutting of the water jet at the mouth of the nozzle. This is achieved by constructively and conceptually changing the motor stator into an aerodynamic dome shape, integrating it into a housing with two or more toothed blades, which have the task of maximizing the eddy of air currents that create empty air space during the exit of water jets from the nozzles. these created water nebulae from the nucleator. At the outlet of the watercourses, a segmental increase in the number of water nozzles was installed. We designed at least one ring-shaped segment on which the water nozzles are mounted. Each segment ring is controlled individually, which enables optimum water supply and ultimately adjusts the amount of it to the existing weather conditions. In the embodiment shown below, four segment rings were used, but these may be 1 + n, which are in the form of a funnel in the direction of air and water outlet, with a small angle a. This enabled maximum cutting off of the jet at the nozzle outlet, which is essential for the formation of ice in the segment of the ring rings.
Tehnična rešitev in bistvena inovativnost naše patentne rešitve je prav v tem, da smo, gledano po izhodni premici smeri zraka, vode in vodne meglice iz nukleatorja, dosegli optimalno dolžino prostora nemešanja vode iz šob in vodne meglice. Gre za spoznanje, da smo s tem dosegli ustvarjanje snežinke okoli ledenega plašča, ki se naredi okoli vodne kapljice pri izhodu iz nukleatorja. Pri nizkotlačnih topovih je glavni problem v tem, da se kristalizacijska zma prehitro vmešajo v osnovno mešanico vode in zraka. Na taki kratki razdalji se vodne kapljice še ne utegnejo dovolj shladit in velik del ledenih zrnc se raztopi namesto, da bi se okrog njih nabrala snežinka. Ta pojav v naravi poznamo kot nastanek žleda, kjer se zaradi vpliva nižjih temperatur ozračja, kot je temperatura same vodne kapljice okli nje naredi tanek leden obroč, ki se razbije pri stiku s trdim predmetom in v hipu zamrzne. Zaradi tega imamo pri snežnih topovi v času obratovanja na izhodni strani vode in zraka velike gmote ledu, ki samo otežuje delo in upravljanje z napravo. Ponavadi so to vse premične naprave, ki se uporabljajo na različnih legah terena, ki gaje potrebno zasnežiti.The technical solution and the essential innovation of our patent solution lies in the fact that, in view of the output direction of the direction of air, water and water mist from the nucleator, we have reached the optimum length of space for mixing water from the nozzles and water mist. It is a realization that this has created the creation of a snowflake around an ice cloak that is made around a water droplet when exiting a nucleator. For low-pressure cannons, the main problem is that the crystallization drags interfere too quickly with the basic mixture of water and air. At such a short distance, the water droplets cannot yet be cooled sufficiently and a large part of the ice granules dissolve instead of accumulating snowflake around them. This phenomenon is known in nature as the formation of ice, where due to the influence of lower atmospheric temperatures, such as the temperature of the water droplet itself, a thin ice ring is formed, which breaks down upon contact with a solid object and freezes instantly. Because of this, snow cannons have a large amount of ice during operation on the outlet side of water and air, which only makes it difficult to operate and operate the device. Usually these are all mobile devices that are used at different positions of the terrain that need to be snowed.
V našem primeru smo s konstrukcijo topa rešili ta problem tako, da se ledena zrnca srečajo z vodnimi kapljicami najmanj 1,3 metra od vodnih šob pri tem ventilator zaradi relativno visokega dinamičnega tlaka ustvarja v notranjosti osnovnega curka votel zračni stožec, v konico katerega vpihavamo kristalizacijska zrna. Prednost tega je v tem, da je voda iz nukleatorja bolj shlajena kot pri ostalih topovih, ki nimajo tako velikega meglenega curka iz nukleatorja, ker se zaradi tega v procesu uporabi več ledenih zrnc kot pri snežnih topovih z malim curkom iz nukleatoija. Namreč pri teh snežnih topovih le-ta vpihava ledena zrnca preblizu vodnim šobam in ker se vodne kapljice ne utegnejo dovolj shladit, se velik del ledenih zrnc stopi in ne opravi svoje funkcije.In our case, the design of the cannon solved this problem so that the ice granules encounter water droplets at least 1.3 meters from the water nozzles, because of the relatively high dynamic pressure, the fan creates a hollow cone inside the base jet, into which the crystallization grain. The advantage of this is that the water from the nucleator is cooler than other cannons that do not have such a large misty jet, because as a result, more ice granules are used in the process than in the case of a small nucleotate jet cannon. Namely, in the case of these snow cannons, it blows the ice granules too close to the water nozzles, and because the water droplets cannot cool down sufficiently, a large part of the ice granules melts and does not perform its function.
Princip delovanja snežnih topov za izdelavo umetnega snega poteka po naslednjem postopku tako, da propelerski snežni topovi izdelujejo sneg iz vode in ob tem posnemajo naravni proces, vendar ga zelo pospešijo in vse skupaj je kot zelo hiter posnetek nastajanja snežinke v naravi. Posledica hitrosti nastajanja je mutacija snežinke, ki v tem primeru nima tiste čarobne oblike zapletenih geometrijskih oblik, temveč izgleda kot nekakšna mini malina.The principle of operation of snow cannons for artificial snow production is as follows, in the following way that propeller snow cannons make snow out of water and imitate the natural process, but accelerate it very much, and all together it is like a very fast shot of snowflake formation in nature. The result of the rate of formation is a mutation of a snowflake, which in this case does not have that magic shape of intricate geometric shapes, but looks like a kind of mini raspberry.
Močan ventilator skrbi za velike količine procesnega zraka, v katerega z vodnimi šobami vpihavamo čim bolj fino vodno meglo, ki jo zračni curek ponese v zrak in ji med potovanjem odvzame toploto, zaradi česar se vodne kapljice počasi hladijo na srednjo temperaturo mešanice procesni zrak - vodna megla. Počasi pod narekovaji zato, ker se vse skupaj dogaja v desetinkah sekunde in redko katera snežinka leti po zraku več kot nekaj sekund.The powerful fan takes care of large quantities of process air, in which the water nozzles inject as fine a water mist as possible, which is carried by the jet into the air and takes away its heat during the journey, causing the water droplets to slowly cool to the middle temperature of the process air - water mixture. mist. Slowly below the quotes because everything happens in tens of seconds, and rarely does any snowflake fly through the air for more than a few seconds.
Medtem ko vodne kapljice letijo po zračnem curku relativno mirujejo, saj jih curek nese v svojem objemu. Od njega so počasnejše le toliko, kolikor zračnega upora mu nudijo. Zaradi relativno mirnega leta se okrog kapljice hitro napravi leden plašč, ki izolira notranjost pred zamrznitvijo. Zunanjost plašča se precej shladi, znotraj pa je tekoča voda in ko ta zmes vode, ovita s tanko plastjo ledu, pade na tla, ledeni plašč poči in hipoma vse skupaj zmrzne. Pojav se v naravi imenuje žled. Na tak način torej ni snega, temveč prvovrstni led.While water droplets fly through the air jet they are relatively still, as the jet carries them in its embrace. They are only slower than the air resistance they provide. Due to the relatively quiet flight, an ice coat quickly forms around the droplet, insulating the interior from freezing. The outside of the jacket is quite cool, but there is running water inside and when this mixture of water, wrapped with a thin layer of ice, falls to the ground, the ice jacket bursts and freezes all together. The phenomenon is called ice in nature. So there is no snow, but first-class ice.
Rešitev je v posnemanju narave, ki v oblake prinese kri stal izacijska zrnca, okrog katerih se prične tvoriti snežinka. Pri snežnih topovih za kristalizacijska zrna skrbijo posebne šobe, ki smo jih imenovali nukleator, iz katerih izpihujemo zrak pod tlakom, vanj pa mešamo majhne količine vode. Med izstopom iz šobe pride do hipnega padca tlaka za 4-6 barov in mešanica zraka ter vode se v trenutku shladi, nastane ledena megla in ta majhna zrnca pihnemo naravnost v osnovni curek vode ter zraka, da se prične tvoriti snežinka okrog ledenega plašč vodnih kapljic, ki prihajajo iz nukleatorja. Takoj se prične verižna reakcija in posledica je sneg.The solution is to imitate nature, which brings to the blood the standing granules around which the snowflake begins to form. For snow cannons, crystallization grains are taken care of by special nozzles called the nucleator, from which we blow out pressurized air and mix small amounts of water into it. During exiting the nozzle, there is a sudden pressure drop of 4-6 bars and the air / water mixture cools instantly, ice fog is formed and these small granules are blown straight into the basic jet of water and air to begin to form a snowflake around the ice cap of the water droplets coming from the nucleator. A chain reaction immediately begins and the result is snow.
To vpihovanje vodne megle v osnovni curek je vidno na sliki 1, ki jo bomo v nadaljevanju teksta bolj podrobno opisali. To je najenostavnejša formulacija in obrazložitev pretvorbe vodnih kapljic v umetni sneg s sistemom vpihovanja vodene megle v osnovni curek v želeni razdalji, ko se optimalno izkoristi tvorjenje ovoja snega, ki jih naredi kapljica vode osnovnega curka pri vezavi z ledeno kapljico iz nukleatorja.This inflow of water mist into the base jet can be seen in Figure 1, which will be described in more detail below. This is the simplest formulation and explanation for the conversion of water droplets into artificial snow by means of a system of blowing water mist into the base jet at the desired distance, when the formation of the snow cover made by the water jet drop of the base jet when bonded with an ice drop from the nucleator is optimally utilized.
Praviloma so vsi topovi do našega izuma, predloženi v pričujoči patentni prijavi, vpihovali to ledeno meglo v osnovni curek mnogo prehitro, daleč pred točko, ko se vzpostavi srednja temperatura med procesnim zrakom in vanj izbrizgano vodo, torej takrat, ko so pogoji za nastanek snega najboljši, saj ima voda najnižjo možno temperaturo. Kako hitro se vpihava megla, je vidno iz slikovnega gradiva na spletnih straneh renomiranih svetovnih proizvajalcev snežnih naprav, kot so: Sufag, Techno Alpin, Demac Lenko, SMI in drugih svetovnih proizvajalcev tozadevnih naprav. Na primer: ameriški proizvajalec snežnih topov Pole Cat ima na videz podobno rešitev kot mi, vendar imajo šobe preveč udarne moči - pritiska (kinetične energije), propeler pa premalo moči (dinamičnega tlaka) in kapljice zaprejo pot megli prehitro in voda še ni dovolj shlajena, da bi se lepo delal sneg.As a rule, all the cannons of our invention, presented in the present patent application, have blown this ice mist into the base jet far too fast, far before the point when the mean temperature between the process air and the injected water is established, ie when the conditions for the formation of snow the best because water has the lowest possible temperature. How quickly the fog blows can be seen in the pictorial material on the websites of renowned global snowmobile manufacturers, such as Sufag, Techno Alpin, Demac Lenko, SMI, and other global manufacturers of snowmobiles. For example: US snowmobile manufacturer Pole Cat seems to have a similar solution to us, but the nozzles have too much impact force - pressure (kinetic energy), the propeller too little power (dynamic pressure) and droplets close the fog too fast and the water is not cool enough to make the snow beautiful.
Pn reseržiranju inovativne ideje s področja prijavljenih patentov smo ugotovili, da obstajajo desetine različnih patentnih prijav, ki se v glavnem nanašajo na različne izvedbe in konstrukcijske rešitve za vpenjanje elektromotorjev z ventilatorji, s sistemi za dovajanje vode in zraka skozi napravo in različno tehnično izvedbo atomizerjev, difiizorjev, ki ji v naši patentni prijavi enačimo s pojmom nukleator, ter z različno izvedbo z okroglim ali večkotnim sistemom izpuha, v katerega so zmontirane vodene šobe.Reserving an innovative idea in the field of patent applications, we have found that there are dozens of different patent applications that mainly relate to different designs and construction solutions for clamping electric motors with fans, systems for supplying water and air through the device, and different technical designs for atomizers, of diffusers, which in our patent application is equated with the term "nucleator" and with a different embodiment with a circular or multi-exhaust system in which the water nozzles are mounted.
V ta namen bomo predstavili nekaj od teh patentov, ki. so po našem mnenju blizu naši rešitvi, ampak so bistvene tehnične karakteristike in konstrukcijske rešitve, ki ne zadevajo naše inovacije predložene v tej patentni prijavi.To this end, we will present some of these patents that. in our opinion, they are close to our solution, but the essential technical characteristics and design solutions that are not relevant to our innovation are presented in this patent application.
US 3761020 predlaga paličasti snežni top, ki ima vsaj dve izhodni šobi in z možnostjo predhodnega hlajenja izhodne vode in zraka, ki se dovaja po dodatnem dvojnem cevovodu. Temu izumu je podobnih nekaj deset svetovnih prijav patentov, a najbližje so naslednji patenti: US 3010660, US 8535168 in W02010025501.US 3761020 proposes a rod-shaped snow cannon having at least two outlet nozzles and with the possibility of pre-cooling the outlet water and air supplied via an additional double pipe. There are several dozen worldwide patent applications similar to this invention, but the closest are the following patents: US 3010660, US 8535168 and W02010025501.
EP 0977968 BI predlaga tudi enojni vertikalni paličasti snežni top, ki ima v sredino postavljen nukleator, v spodnji strani okoli okrogle cevi so nameščene vodne šobe. Temu izumu sledijo že prijavljeni naslednji izumi, ki so si zelo blizu po tehnični rešitvi. Gre za naslednje izume CH 682 694 05, US 5004151 in DE40 33 310 Al.EP 0977968 BI also proposes a single vertical rod-shaped snow cannon with a nucleator in the center, with water nozzles mounted in the underside around the round tube. This invention is followed by the following inventions, which are very close to the technical solution. These are the following inventions CH 682 694 05, US 5004151 and DE40 33 310 Al.
V glavnem so v zgoraj navedenih izumih obravnavani paličasti snežni topovi, ki imajo nukleator ali so z drugačnim sistemom vpihovanja zrnaste megle ter tudi z različnimi učinki pri eksploataciji.In the foregoing, the invention relates generally to rod-shaped snow cannons that have a nucleator or are of a different type of fog, and also have different effects in exploitation.
Najbližje naši idejni rešitvi je izum prijavljen pod št. EP 011 29558 Al, ki predlaga snežni top s tunelskim dovodom zraka in prisilno cirkulacijo s pomočjo elektro motorja. Pri tem izumu so paketno vstavljene šobe za dovajanje vode v večkotno obliko tako, da je na izvedbenem primeru prikazano sedemkotno ploskovno telo, ki ima več nizov postavljenih šob v horizontalo. Druga značilnost za ta izum je v tem, da se mešanje vode in zračnega tlaka izvaja v dovodni cevi po posameznem segmentu ploskovnih sestavov.Closest to our conceptual design, the invention is disclosed under no. EP 011 29558 Al proposing a snow cannon with a tunneled air supply and forced circulation by means of an electric motor. In the present invention, nozzles are provided for packing water in a polygonal shape so as to show, in the embodiment, a seven-angle planar body having several sets of horizontal nozzles. Another feature of the present invention is that the mixing of water and air pressure is carried out in the inlet pipe by individual segment of the planar assemblies.
Kanadski izum CA 2847320A1 predlaga napravo za izdelavo snega, ki vključuje osnovne sestave, kot so: kolektor, nukleator v obliki obročaste komore in množico vodnih šob. Nukleator kot obročasta komora je konfiguriran za sprejem zmesi zrak-voda iz prvega izliva, pn tem je prvi izliv usmeijen tangencialno k neposredni mešanici zraka in vode v nucleato. Torej je nukleator sestavljen iz obročaste komore, ki usmeija vodno meglico, kar se bistveno razlikuje od naše inovativne ideje nukleatorja.The Canadian invention CA 2847320A1 proposes a snowmaking device that includes basic compositions such as: a collector, a ring-shaped nucleator and a plurality of water nozzles. The nucleator as a annular chamber is configured to receive an air-water mixture from the first spout, wherein the first spout is directed tangentially to the direct mixture of air and water into the nucleate. So the nucleator is made up of a ring chamber that laughs at the water mist, which is significantly different from our innovative nucleator idea.
Na vseh spletnih posnetkih zgoraj omenjenih konkurenčnih topov je lepo viden močno turbulenten tok procesnega curka. Takoj, ko zapusti snežni top, se prične bogato kaditi in valiti turbulenca je močno prisotna in zelo dobro vidna. Vse to se prične ustvarjati na statorjevih lopaticah.The highly turbulent flow of the process jet can be clearly seen on all the online clips of the above-mentioned competing cannons. As soon as it leaves the snow cannon, it begins to smoke abundantly and the turbulence is strong and visible. This is all starting to happen on the stator blades.
Inovativna nota naše tehnične rešitve, ki se tehnično razlikuje od do sedaj znanih izdelanih, patentiranih in nepatentiranih tehničnih izvedenk in rešitev snežnih topov jev tem, da smo mi spremenili sistem nukleatoija in poskrbeli za mešanje ledene megle z osnovnim curkom v točki ali tik za točko, kjer se izenači srednja temperatura vseh elementov v osnovnem procesnem curku.An innovative note of our technical solution, which is technically different from the known, patented and unpatented technical designs and snow-cannon solutions so far, in that we have modified the nucleatoi system and made the fog blend with the base jet at point or just behind point, where the mean temperature of all the elements in the basic process jet is equalized.
Da smo prišli do tega, smo napravili naslednje:To come to this, we did the following:
1. zmogljiv ventilator z dovolj dinamičnega tlaka, da odreže vodni stožec tik ob šobah,1. a powerful fan with enough dynamic pressure to cut off the water cone right next to the nozzles,
2. uporabili smo posebne šobe, ki s Coanda efektom močno razbijejo vodo v majhne delce, ki jih zaradi šibke inercije zračni curek lažje potegne s sabo,2. We have used special nozzles which, with the Coanda effect, sharply break the water into small particles, which, due to the weak inertia, are easier to pull with them,
3. namestili smo centralno enoto nukleator, ki piha ledeno meglo skozi prazen prostor atomizeija v center curka,3. We installed a central nucleator unit that blows ice fog through the empty atomize space into the center of the jet,
4. vpetje statorja elektromotorja smo izvedli z zobatimi lopaticami na izhodu zračnega tlaka tako, da smo na tej strani izdelali steno z eno ali več bradavicami, ki ustvarjajo maksimalno vrtinčenje zračnih tokov,4. the mounting of the stator of the electric motor was carried out with a toothed blade at the outlet of the air pressure by producing a wall with one or more nipples on this side, creating a maximum swirl of air currents,
5. vgradili smo 1+n število segmentnih obročev z vodnimi šobami, ki so gledano v smeri izhoda zraka in vode postavljeni v obliki lijaka, z malim razširitvenim kotom a,5. We installed a 1 + n number of segment rings with water nozzles, which are in the direction of the air and water outlet in the form of a funnel, with a small expansion angle a,
6. razporedili smo vodne šobe v obliki lijaka tako, da se neprekrivajo izhodni curki vode s curki iz sosednjih šob.6. We arranged the funnel-shaped water nozzles so that the outlet jets of water were non-overlapping with the jets from adjacent nozzles.
Zaradi zmogljivega propeletja na ventilatoiju in majhne inercije vodnih kapljic potegne iz zračnih puš vse kapljice po svoji poti ter se na sredini tega zračnega curka pojavi 1,3 - 1,5 m dolg votel stožec, kjer zaradi prepiha ni vode.Due to the powerful propeller on the vent and the small inertia of the water droplets, it pulls all the droplets out of the air bushings in its path and a hollow cone appears in the middle of this air jet, where there is no water due to draft.
Sredinski nukleatorji pihnejo ledeno meglo točno v konico tega centra zračnega stožca, da čim bolj podaljšamo razdaljo med vodnimi šobami in točko srečanja z ledeno meglo ter na tak način damo vodi možnost za izenačitev temperatur s procesnim zrakom. V našem primeru je ta razdalja večja od 1,3 m in to je več ali manj pravilo za vse topove.Center nucleators blow ice fog right into the tip of this center of the air cone to maximize the distance between the water nozzles and the ice fog meeting point, thus giving water the ability to equalize temperatures with process air. In our case, this distance is greater than 1.3 m and this is more or less the rule for all cannons.
Zaradi tega imamo bistveno zmogljivejši snežni top, ki v vseh parametrih prekaša nam poznano konkurenco. V Lechu smo na testu poizkusno izdelovali umetni sneg pri -1,5 0 C vlažne temperature. Tega ne zmore noben drug propelerski snežni top. Konkurenca starta nekje med -2,5 0 C in -2,8 0 C. Ob tem primerljivi topovi porabijo med 26 in 30 Kw, mi pa največ 21 Kw. W Lechu smo porabili le 17 Kw, ker zaradi toplega vremena ni bilo treba vklapljati grelcev šob.Because of this, we have a significantly more powerful snow cannon, which in all parameters surpasses the known competition. In Lech was tested experimentally produced artificial snow at -1.5 0 C wet temperature. No other propeller snow cannon can do that. The competition starts somewhere between -2.5 0 C and -2.8 0 C. At the same time, comparable cannons consume between 26 and 30 Kw, but we do not exceed 21 Kw. We only consumed 17 Kw of W Lech because of the warm weather we did not have to switch on the nozzle heaters.
Pri -5 0 C vlažne temperature dela najboljša konkurenca sneg iz 120 1/min do 150 1/min vode, mi delamo enak sneg iz 190 1/min vode, kar je 25-60 % razlike ob 24-33 % manjši porabi energije.At -5 0 C humid temperatures, the best competition is snow from 120 l / min to 150 l / min water, we make the same snow from 190 l / min water, which is 25-60% difference with 24-33% lower energy consumption.
S temi preizkusi in opravljenimi testi smo dokazali, da lahko energetsko porabo snežnega topa celo zmanjšamo za 2 do 2,5 kW in bomo obdržali enako zmogljivost. Bistvo tehnične rešitve je v tem, da po našem izumu, predloženem v pričujoči patentni prijavi, vsa ali skoraj vsa ledena megla sodeluje pri izdelavi snega. Poleg termodinamičnega izboljšanja zmogljivosti smo poskrbeli še za aerodinamično izboljšanje pri izhodu samega vodnega curka in v nadaljevanju snežink umetnega snega, ki ga izpiha naš snežni top. To smo dosegli tako, da je prvi segment pri nukleatoiju ima najmanjši radius, ki se pri naslednjem veča in tako naprej, kar nam omogoča videz lijaka postavitve potrebnega števila segmentnih obročev.With these tests and the tests we have done, we have shown that the energy consumption of a snow cannon can even be reduced by 2 to 2.5 kW and will maintain the same capacity. The essence of the technical solution is that according to our invention, presented in the present patent application, all or almost all ice fog is involved in the production of snow. In addition to thermodynamically improving performance, we also made aerodynamic improvements to the outlet of the water jet itself and, in the sequel, snowflakes of artificial snow blown by our snow cannon. This is achieved by the fact that the first segment in the nucleatoi has the smallest radius, which increases in the next, and so on, which gives us the appearance of a funnel to place the required number of segment rings.
Pri proizvajalcih, ki uporabljajo vpihovanje ledene meglice na razdalji do 50 cm od vodnega curka, sodeluje pri izdelavi le majhen del ledene megle, ki čisto slučajno prileti na dovolj podhlajeno vodno kapljico ali pa se v praznem prostoru med kapljicami prebije dovolj daleč vstran od snežnega topa, da lahko zadene dovolj hladno vodno kapljico. Vsa ostala ledena zrnca se preprosto stopijo ob srečanju s pretoplo vodo in na tak način gre v nič tudi do 75 % ledenih zrn iz vodene megle.For manufacturers using ice fog blowing up to 50 cm from the water jet, only a small portion of the ice fog is involved, which accidentally approaches a sufficiently cooled water droplet or breaks far enough away from the snow cannon in the empty space between the droplets. to hit a cool enough water drop. All other ice grains are simply melted upon encountering the water that has been melted, and thus, up to 75% of the water grains of water mist are zeroed in.
Z našo koncepcijo snežnega topa in posebno aerodinamično obliko statorja elektromotorja in lijačno postavitvijo segmentnih obročev ter tehnologijo izdelave nukleatoga in, v nadaljevanju z razporeditvijo vodnih šob in posamičen vklop segmentnih obročev vodnih šob, ki spremlja naš proizvod, smo dosegli določeno finančno razbremenitev naših uporabnikov, ker smo v velikem procentu znižali proizvodne stroške in s tem ceno proizvoda, a po drugi strani smo dvignili tehnični nivo snežnega topa, da z manj porabljene energije dosega boljše rezultate.With our conception of the snow cannon and the special aerodynamic shape of the stator of the electric motor and the funnel placement of the segment rings and the technology of nucleatog and, in the further arrangement of the water nozzles and the individual activation of the segment rings of the water nozzles accompanying our product, we have achieved some financial burden for our users. we reduced production costs and the price of the product by a large percentage, but on the other hand, we raised the technical level of the snow cannon to achieve better results with less energy consumed.
Po drugi strani smo pri vzdrževanju po dolgem času obratovanja dosegli minimalni vložek za preventivni pregled in poseg samega proizvoda pri servisiranju, ker se zaradi nepogoste zaledenelosti vodnih šob v izhodni tuljavi le-te manj obrabljajo. V ta namen smo dodatno vgradili gretje teh šob, kar ni predmet te patentne prijave.On the other hand, during maintenance after a long time of operation, the minimum input for preventive inspection and the intervention of the product in servicing has been reached, because of the frequent icing of the water nozzles in the output coil, they are less worn. For this purpose, we additionally installed the heating of these nozzles, which is not the subject of this patent application.
Poenostavljeni so postopki servisiranja in bistveno zmanjšani stroški servisa, kar vpliva na tehnično razpoznavnost našega snežnega topa, izdelanega s posebnim elektromotoijem, nukleatoijem in izhodno tuljavo z obročastimi segmenti na katere je vgrajeno 1+n vodnih šob po pričujoči patentni prijavi.Service procedures are simplified and service costs are significantly reduced, which affects the technical visibility of our snow cannon made with a special electric motor, nucleatoi and an output coil with annular segments with 1 + n water nozzles installed according to the present patent application.
To, kar je povedano v zgornjih stavkih, drži in zagotovo velja, da do danes nihče ni naredil takšne konstrukcijske koncepcije snežnega topa, ki po eni strani predstavlja enostavnost izdelave, a po drugi stani zagotavlja primemo in dolgotrajno eksploatacijo v ekstremnih okoljih, v katerih obratujejo tozadevne naprave. Določene konstrukcijske rešitve na elektromotoiju in njegovem vpetju v konstrukcijo, na nukleatorju in izhodni tuljavi z obročastimi segmenti s šobami, ki jih bomo podrobneje opisali v nadaljevanju spisa, ko bomo opisovali posamezne dele, prikazani na sliki oz. skici 1 in detajlneje pogled na koncepcijo obročastih segmentov in razporeditve vodnih šob na njih, prikazani na sl. 2 in 3.What is said in the sentences above is true, and it is certainly true that to date no one has made such a conceptual design of a snow cannon, which, on the one hand, represents ease of manufacture, but on the other hand, provides prime and long-term exploitation in the extreme environments in which they operate the devices involved. Certain structural solutions on the electromotor and its mounting in the structure, on the nucleator and the output coil with annular segments with nozzles, which will be described in more detail in the continuation of the file when describing the individual parts shown in the figure or. 1 and a more detailed view of the conception of annular segments and the arrangement of water nozzles thereon, shown in FIG. 2 and 3.
Na drugi strani pa smo z rešeržiranjem znanih tehničnih rešitev podobnih naprav na svetovnem nivoju prišli do spoznanja, daje naša rešitev enkratna in predstavlja novost na tem področju, kar se kaže v tej patentni prijavi in njenih patentnih zahtevkih.On the other hand, by designing well-known technical solutions of similar devices at the world level, we came to the realization that our solution is unique and represents a novelty in this field, which is reflected in this patent application and its claims.
Novost je predvsem v drugačni zasnovi in potem rešitvi tehničnih problemov, ki so se pojavljali v postopku snovanja, ker je bil cilj visoko postavljen, a to je najpomembnejša lastnost samega postopka koncipiranja novega načina uporabe nosilnih lopatic statorja elektromotorja, enostavnost konstrukcije nukleatoija, ki se kaže v izpopolnitvi ter doseganju zadanega cilja ter oblikovno tehnični namestitvi obročastih segmentov in vodnih šob v izhodni tuljavi snežnega topa, katerem je v celovitosti omogočeno odrezovanje vodnega curka na samem izhodu šobe, a da le-ta ne ovira in ne vpliva na delovanje najbližjih šob. Hkrati je visoko komercialen proizvod in kot takšen je našel široko uporabo na vseh smučiščih, zahvaljujoč nepričakovanim rezultatom in lastnostim uporabnosti in kakovosti, da lahko deluje tudi pri višjih temperaturah okolja, v katerih podobni proizvodi dosegajo polovičen izkoristek ter večjo porabo energije.The novelty lies mainly in the different design and then the solution of the technical problems encountered in the design process, since the goal was set high, but this is the most important feature of the process of conceiving a new way of using the electric motor stator carrier blades, the simplicity of the nucleatoi construction that is evident. in the refinement and achievement of the set goal and the technical and technical installation of the annular segments and water nozzles in the outlet coil of the snow cannon, which is fully capable of cutting off the water jet at the outlet of the nozzle without interfering with or affecting the operation of the closest nozzles. At the same time, it is a highly commercial product and as such has found wide use in all ski resorts, thanks to its unexpected results and its usability and quality, so that it can also operate at higher ambient temperatures in which similar products achieve half efficiency and higher energy consumption.
Izum bomo prikazali s skico 1, ki predstavlja bočni pogled našega snežnega topa, kateri vsebuje okroglo votlo močnostno ohišje, v katerega je umeščen elektomotor z močnim lopaticami ventilatoija, ki so konstrukcijsko in oblikovno prilagojene kapacitivnim potrebam za optimalno izdelavo umetnega snega, nukleator za ustvarjanj e vodne meglice ter na izhodu tuljava z vodnimi šobami. Nadalje bomo na skicah 2 in 3 prikazali tehnično rešitev posameznih obročastih segmentov in na njih razporeditve vodnih šob.The invention will be illustrated by Figure 1, which is a lateral view of our snow cannon containing a circular hollow power housing housing an electric motor with powerful ventilation blades that are structurally and formally adapted to the capacity requirements for optimal artificial snowmaking, a nucleator for creating e water nebulae and the outlet coil with water nozzles. Furthermore, in Figures 2 and 3, we will show the technical solution of the individual annular segments and their arrangement of water nozzles.
Za boljše razumevanje zgoraj napovedanega kratkega opisa temeljnih skic naše inovativne ideje, ki se kaže v obliki snežnega topa in njegovih temeljnih sestavov kot udarnega produkta, ki je nastal na temelju snovanja naše inovativne ideje, prikazane v tej patentni prijavi in njene risbe, katero bomo v nadaljevanju teksta opisali.For a better understanding of the foregoing brief description of the basic sketches of our innovative idea, which is manifested in the form of a snow cannon and its basic components as a percussion product, formed on the basis of the conception of our innovative idea shown in this patent application and its drawing, which will be incorporated herein by reference. described below.

Izum prikazan na sl. 1, predstavlja bočni pogled na sestavljen snežni top z okroglim votlim ohišjem 1, na katerega je v notranjosti prittjen elektromotor 3, s pomočjo vsaj z dvema pritrdilnima lopaticama statorja 4. Na vhodni zračni strani A je na elektomotoiju 3 koncipiran ventilator z lopaticami 2, ki so konstrukcijsko in oblikovno izvedene tako, da zagotavljajo optimalen dovod zračnih tokov A skozi ohišje 1 našega snežnega topa. Gledano po horizontali v smeri pretoka zraka A je stator elektromotorja 3 aerodinamično oblikovan, s tem daje takoj za njegovo konico umeščen nukleator 6, ki je povezan z ohišjem 1 vsaj z dvema pritrdilnima cevastima nosilcima 6.1, skozi katera prihaja voda za ustvarjanje vodne meglice 6.2. V nadaljevanju opisa horizontalnega pogleda naše sl. 1 je na izhodu snežnega topa umeščena tuljava z nekaj nizih - vrst obročastih segmentov 5.0.2, prikazani na sl. 2 in 3 z vodnimi šobami 5 iz katerih prihajajo pod velikim pritiskom curki vode in vodnih kapelj 5.1. Vodne šobe 5 so tako razporejene po okroglem obodu tuljave ali obročastega segmenta 5.0.2 slika 3, ki je vsaj, v 1 + n izvedbi, sestavni del ohišja 1 našega vodnega topa. Bistvo te neenakomerne razporeditve je v tem, da v fazi delovanja izpihujejo vodni curek 5.1 tako, da ne ovira vodni curek na naslednji šobi 5, gledano v smeri izpihovanja. Druga bistvena značilnost je v tem, da je ta vodni curek 5.1 odrezan na samem izhodu iz šobe 5 zaradi delovanja turbulence in pritiska zračnih tokov 4.1.1. in konstrukcijske postavitve obročastih segmentov 5.0.2 pod kotom a prikazan na sl. 2, ki predstavlja razširitveni kot nagiba segmentnih obročev v obliki lijaka in je v nagibu od 2 do 8 stepeni.The invention shown in FIG. 1 is a lateral view of a compound snow cannon with a circular hollow housing 1 to which an electric motor 3 is attached internally, by means of at least two stator blade mounting blades 4. On the inlet air side A, a blade fan 2 is conceived on the electromotive 3. they are designed and designed to provide optimum airflow A through the housing of our snow cannon. Horizontally, in the direction of the air flow A, the stator of the electric motor 3 is aerodynamically shaped, thereby placing immediately after its tip a nucleator 6, which is connected to the housing 1 by at least two fixing tubular supports 6.1 through which water flows to create a water mist 6.2. Below, a description of the horizontal view of our FIG. 1, there is a coil at the exit of the snow cannon with some series - types of annular segments 5.0.2 shown in FIG. 2 and 3 with water nozzles 5 from which water jets and water droplets come under high pressure 5.1. The water nozzles 5 are thus arranged along the circumferential circumference of the coil or annular segment 5.0.2 Figure 3, which is at least, in 1 + n design, integral to the housing 1 of our water cannon. The point of this uneven arrangement is that, during the operating phase, they blow the water jet 5.1 in such a way that it does not interfere with the water jet on the next nozzle 5 when viewed in the direction of the blowing. Another essential feature is that this water jet 5.1 is cut off at the outlet of the nozzle 5 due to the operation of the turbulence and the pressure of the air flows 4.1.1. and the structural arrangements of the annular segments 5.0.2 at an angle a shown in FIG. 2, which represents the expansion angle of inclination of the hopper-shaped segment rings and is in the inclination of 2 to 8 degrees.
To je potrebno zaradi tega, da dosežemo minimalno razdaljo a, ki predstavlja minimalno velikost votlega suhega - zračnega stožca, minimalno 1,3 m ali več, zračne mešanice, kije potrebna za dosego optimalne mešanice vode 5.1 sl.l iz šob 5 z vodno meglico 6.2 iz nukleatoija 6 in vrtinčastih zračnih tokov 4.1.1 ali mešanice tlačne in podtlačne mejne zračne plasti, ki prihaja iz elektromotoija 3. Ta ledena zmes prikazana na sl. 1 se ustvari v konici stožčastega turbulentnega toka vodne meglice 4.1.1.1 na ta način, da smo v tej razdalji dosegli takšen temperaturni padec ledenega ovoja okoli kapljic vode v meglici 6.2, da jih z lahkoto tvori ledena kroglica iz vodne meglic 6.2 s pomočjo zračnega toka 4.1.1 na katere se vežejo vodene kapi 5.1 in se tako tvorijo snežinke 7. Za boljše razumevanje bomo v nadaljevanju predstavili termodinamiko zračnih 4.1.1 in vodnih tokov 5.1 in 6.2, ki se odvijajo na ustju našega snežnega topa.This is necessary to achieve the minimum distance a representing the minimum size of a hollow dry air cone, minimum 1.3 m or more, the air mixture required to achieve the optimum water mix of 5.1 sl.l from nozzles 5 with a water mist 6.2 from nucleatoi 6 and eddy air currents 4.1.1 or a mixture of pressure and pressure boundary air layer coming from the electromotion 3. This ice mixture is shown in FIG. 1 is created at the tip of the conical turbulent flow of the water mist 4.1.1.1 in such a way that a temperature drop of the ice sheath around the water droplets in the mist 6.2 is obtained in such a distance that they are easily formed by an air ball of water mist 6.2 through the air flow 4.1.1 to which the water droplets 5.1 attach and thus form snowflakes 7. For better understanding, we will now present the thermodynamics of the air 4.1.1 and water flows 5.1 and 6.2 that take place at the mouth of our snow cannon.
Nastajanje vrtinčastega zračnega toka na klasičnem statoiju povzroči delovanje lopatic ventilatoija 2 do separacije mejne zračne plasti 4.1.1 ali in na zadnjem robu statorja se pojavi zastojni rotor - vrtinčenje, v nadaljevanju teksta bomo uporabljali izraz rotor, z amplitudo, enako debelini mejne zračne plasti 4.1.1. Teh rotoijev mešanice tlačne in podtlačne mejne zračne plasti 4.1.1 je točno toliko, kolikor je statorskih lopatic 4 in se slišijo podobno kot tuljenje vetra čez malce debelejšo jekleno žico. Ti zastojni rotorji mešanice tlačne in podtlačne mejne zračne plasti 4.1.1 generirajo večji rotor in ob izhodu iz topa ima curek turbulenco z enakim številom osnovnih rotoijev mešanice tlačne in podtlačne mejne zračne plasti 4.1.1, kot je število statorskih lopatic 4. Seveda gre v to mešanje ogromno energije, slabost je tudi izguba najtežjih kapljic iz curka, saj jih centrifugalna sila vrže iz curka in padejo dol kot zelo moker sneg 7. Zadeva se da rešiti, ampak na škodo celotnega izkoristka in predvsem dometa snežnega topa. Ta turbulenca je najlepše izražena na osnovni spletni strani firm Sufag m Demac Lenko, ko snežni topovi bogato bruhajo sneg v jasno nebo, ampak to je čista turbulenca in nič drugega.The formation of a vortex airflow on a classical statue causes the fanatoi 2 blades to function until the separation of the boundary air layer 4.1.1 or a stagnant rotor appears on the posterior edge of the stator; hereinafter we use the term rotor with an amplitude equal to the thickness of the boundary air layer 4.1 .1. These rotoions of the mixture of pressure and pressure boundary layer 4.1.1 are exactly as many as the stator blades 4, and they sound much like wind winding over a slightly thicker steel wire. These stalled rotors of the mixture of pressure and pressure boundary air layer 4.1.1 generate a larger rotor and, upon leaving the cannon, the jet has turbulence with the same number of basic rotors of the mixture of pressure and pressure boundary air layer 4.1.1 as the number of stator blades. this mixing of enormous energy, the disadvantage is also the loss of the heaviest droplets from the jet, as the centrifugal force throws them from the jet and falls down like very wet snow 7. The matter is salvageable, but to the detriment of the overall efficiency and especially the reach of the snow cannon. This turbulence is best expressed on the Sufag m Demac Lenko company homepage when snow cannons vomit snow into the clear sky, but it is pure turbulence and nothing else.
Na našem novem izdelku izdelanem po pričujoči patentni prijavi kot prototip za preizkušanje prikazan na slikah 1, 2 in 3, smo na izhodnem robu vsake statorske lopatice 2 napravili vsaj tri zaobljene zobe-bradavice 4.1. Tudi pri nas pride do separacije mejne plasti mešanica tlačne in podtlačne mejne zračne plasti 4.1.1, na podtlačni ploskvi statorjevih lopatic 4, vendar ti zobje-bradavice 4.1 poskrbijo za malce daljše mešanje tlačne in podtlačne mejne ploskve 4.1.1. Na tak način dodatna energija stisne podtlačno mejno plast oz. mešanico tlačne in podtlačne mejne zračne plasti 4.1.1 nazaj k lopatici 4 in z mešanjem obeh plasti se pojavi dovolj energije, ki zarotirato mešalno mejo oz. mešanico tlačne in podtlačne mejne zračne plasti 4.1.1 ob zobcih-bradavicah 4.1 ter jo zapusti na konici zoba-bradavice 4.1 v obliki majhnega vrtinca 4.1.1. Glede na to, da ima vsaka lopatica 4 po tri zobce 4.1, lopatic je pa trinajst, imamo ob izhodu iz snežnega topa 39 majhnih rotorčkov ali mešanic tlačnih in podtlačnih mejnih zračnih plasti 4.1.1 , ki so dovolj zgoščeni in dovolj majhni, da posnemajo laminami tok.We have made at least three rounded wart teeth at the exit edge of each stator blade 2 on our new product, made after the present patent application as a prototype for testing, shown in Figures 1, 2 and 3. Here too, the boundary layer is separated by a mixture of pressure and pressure boundary air layer 4.1.1, on the pressure plane of the stator blades 4, but these teeth-warts 4.1 provide a slightly longer mixing of the pressure and pressure boundary plane 4.1.1. In this way, the additional energy compresses the compressive boundary layer or the. the mixture of pressure and pressure boundary air layer 4.1.1 back to the blade 4 and by mixing the two layers, sufficient energy is generated to rotate the mixing boundary or. a mixture of pressure and pressure boundary air layer 4.1.1 along the nipple teeth 4.1 and leave it at the tip of the nipple tooth 4.1 in the form of a small vortex 4.1.1. Given that each blade 4 has three prongs of 4.1 and the blades are thirteen, there are 39 small rotors or mixtures of pressure and pressure boundary air layers 4.1.1 that are thick enough and small enough to imitate when leaving the snow cannon. laminami flow.
Bolj usmerjen zračni tok je pri našem topu lepo viden po presenetljivi značilnosti, ko gledaš naš top med delovanjem in ga vizualno primegaš s konkurenco ali pa z našimi starejšimi izdelki dobiš občutek, da ima vsaj 2/3 manjšo zmogljivost in bistveno manjši domet od katerega koli konkurenta. Rezultat je seveda obraten in mi si ta pojav razlagamo s tem, da pri nas curek leti mnogo manj turbulentno in obstaja mnogo manj možnosti, da se katera od snežink zalesketa v soncu, ker jih preprosto ne vrtinči in se ne nastavijo soncu nekaj krat na sekundo. To smo dokazali s testiranjem našega snežnega topa v Lechu, kjer se lepo vidi povsem laminaren zračni tok vsaj a = 1,5 m vstran od topa. Ob pazljivem pogledu je na sredini viden malce bogatejši stebriček curka 4.1.1.1 sl. 1 in to so kristalizacijska zrna 6.2 izpihana s kompresoijem. Srečanje med kristalizacijskimi zrni 6.2 in vodnimi kapljicami 5.1 je točno v točki 4.1.1.1, kjer potem osnovni curek zarotira v umetni sneg 7.The more directional airflow is clearly visible in our cannon for its striking feature when you look at our cannon while operating and visually blend it with the competition, or with our older products you get the feeling that it has at least 2/3 less capacity and significantly less range than any competitor. The result is, of course, the reverse, and we interpret this phenomenon by saying that the jet flies far less turbulent in our country and there is much less chance of any snowflakes sticking in the sun because they simply do not swirl and do not set to the sun several times per second. . We proved this by testing our snow cannon in Lech, where a perfectly laminar airflow at least a = 1.5 m away from the cannon can be clearly seen. A careful view shows a slightly richer jet stream 4.1.1.1 in the middle. 1 and these are the crystallization grains 6.2 blown by compression. The encounter between crystallization grains 6.2 and water droplets 5.1 is exactly in 4.1.1.1, where the base jet is then immersed in artificial snow 7.
Tudi ta rešitev je pomembna za vzpostavitev čim daljšega votlega-suhega stožca 4.1.1 v osnovnem curku, ki ga obdajata zunanji vodni curek 5.1 in notranja vodna meglica 6.2. Na sliki 2 je konstrukcijsko ponazorjena tuljava s štirimi segmentnimi obroči 5.0.2, v katere so vgrajene vodne šobe 5 in prikaz njihovih posamičnih povezav s cevmi 5.0.1 za dotok vode v šobo 5. Bistveno te rešitve je v tem, da mi koncipiramo snežni top s toliko obročastih segmentov 5.0.2, koliko jih želi uporabnik imeti. Ti obročasti segmenti 5.0.2 so postavljeni, gledano v smeri pretoka zraka A sl. 1, v obliki lijaka pod kotom a, ki predstavlja razširitveni kot nagiba segmentnih obročev in je konstrukcijsko opredeljen med 2 in 8 stopinjami. Vpenjanje dveh obročastih segmentov 5.0.2 sl. 2 in 3 je izvedeno s posebnimi samozateznimi spojkami 5.0.3, ki imajo tudi tehnično možnost nastavitve-regulacije kota nagiba a.This solution is also important for establishing the longest hollow-dry cone 4.1.1 in the base jet surrounded by an external water jet 5.1 and an internal water mist 6.2. Figure 2 shows a construction coil with four segment rings 5.0.2, which incorporate water nozzles 5 and shows their individual connections with pipes 5.0.1 to supply water to the nozzle 5. It is essential that we conceptualize the snow top with as many 5.0.2 ring segments as the user wants. These annular segments 5.0.2 are positioned in the direction of air flow A FIG. 1, in the form of a funnel at an angle a, representing the expansion angle of inclination of the segment rings, and which is structurally defined between 2 and 8 degrees. Clamping the two annular segments 5.0.2 fig. 2 and 3 are made with special self-tightening couplings 5.0.3, which also have the technical possibility of adjusting-adjusting the tilt angle a.
Druga in zelo pomembna inovativna rešitev je v neenakomerni linijski razporeditvi vodnih šob 5 prikazani na sliki 3, kjer curek vode iz šobe 5 ne ovira in neprekriva curka iz sosednjih šob 5. S tem smo dosegli maksimalno razpršenost vodnih kapi 5.1 prikazani na sl.l, ki se v nadaljevanju izhodne poti vežejo na ledene vodne kapljice 4.1.1.1, ki jih pod pritiskom izbrizga kompresor skozi nukleator 6. S testiranji in regulacijo pritiskov vode, zraka iz kompresorja in pretokov zračnih vrtincev 4.1.1 sl. 1 smo ugotovili, daje optimalna razdalja ali mesto mešanja med ledenimi vodnimi kapljicami 4.1.1.1 in vodnimi kapljicami potisnjene z vodnimi črpalkami, je to na minimalni ali večji razdalji kot je a = 1,3 m.Another and very important innovative solution is shown in Fig. 3 in the uneven line arrangement of water nozzles 5, where the jet of water from the nozzle 5 does not obstruct and the continuous jet from the adjacent nozzles 5. This achieves the maximum dispersion of water drops 5.1 shown in FIG. which in the continuation of the exit path binds to ice water droplets 4.1.1.1 which are ejected under pressure by the compressor through a nucleator 6. By testing and regulating the pressures of water, air from the compressor and airflows 4.1.1. 1, we found that the optimal distance or mixing location between ice water droplets 4.1.1.1 and water droplets was suppressed by water pumps, that is, at a minimum or greater distance than a = 1.3 m.
V zgornjem tekstu smo opisali samo konkretne dele našega snežnega topa in ga primerjali s podobnimi napravami, ki so že v eksploataciji, ampak imajo zelo kratek domet curka vodne meglice. Naš snežni top je izdelan po pričujoči patentni prijavi in se resnično pojavlja z že opisanimi ključnimi deli, ki smo jih predstavili v izvedbenem primeru ter podkrepili s priloženo skico in njeni detajli - pogledi A in B. Izvedbeni primer nam ponazarja snežni top z elektromotorjem - ventilatorjem, povezanim z ohišjem snežnega topa s trinajstimi statorskimi lopaticami, z nukleatorjem in izhodnim delom zraka in vode, ki se vidi kot tuljava sestavljena iz obročastih segmentov, v katero so umeščene šobe za izpust vode pod velikim pritiskom.In the text above, we have only described the specific parts of our snow cannon and compared it with similar devices already in operation but having a very short jet of water mist. Our snow cannon is made according to the present patent application and really appears with the key parts already described, which we presented in the embodiment and supported by the attached sketch and its details - views A and B. The embodiment illustrates the snow cannon with an electric motor - fan connected to a snow cannon housing with thirteen stator blades, a nucleator and an outlet of air and water, which is seen as a coil composed of annular segments into which high pressure water nozzles are placed.
Rezime principa delovanja vseh zgoraj navedenih delov je v tem, da voda prihaja iz zajetja preko črpalk in filtrov do šob pod velikim pritiskom, ker se razprši in v zračnem toku, ki ima manj kot nič stopinj Celzija, podhladi. Tako dobimo podhlajeni dež, poznan iz narave kot žled, ali podobno kot pri letalih, ko pade podhlajena kapljica na krilo in tam zamrzne. To se dogaja na zunanjem obroču šob, kjer je več obročev šob in jih lahko vklapljamo parcialno, glede na potrebo ter s tem spreminjamo razmerje voda/zrak.A summary of the principle of operation of all the above parts is that the water comes from the sump via pumps and filters to the high pressure nozzles because it is dispersed and cools in an air stream of less than zero degrees Celsius. In this way, we get sub-cooled rain, known from nature as ice, or similar to airplanes, when a sub-cooled droplet falls on a wing and freezes there. This happens on the outer ring of the nozzles, where there are several nozzle rings and can be switched on partially, as needed, thus changing the water / air ratio.
Na sredini za aerodinamično obliko statoija elektromotoija je nukleator-atomizator, kjer se meša mala količina vode in zrak iz kompresorja in tako dobimo meglico, katera se brizga v zračni tok, ki ga ustvaijajo propeleiji ventilatorja, ki je za vsemi šobami.In the middle of the aerodynamic form of the statue of electromotions is a nucleator-atomizer, which mixes a small amount of water and air from the compressor to produce a nebula which is injected into the air stream created by the fan propellers behind all the nozzles.
Ventilatorje bistveno močnejši kot znani sistemi in potiska vodne kapljice iz šob (zunanji obod) in meglico iz njene sredine nastanka bistveno dlje kot obstoječi sistemi. Zato se vodne kapljice na tej daljši razdalji mnogo bolj podhladijo kot pri obstoječih sistemih in ko pridejo v stik z meglico iz nukleatoija v prostor za atomiziranje vodne meglice (ki deluje kot kristalografska kal pri ohlajanju taline ali kal pri tvorjenju oblaka-prašni delci itd.), in se takoj spremeni agregatno stanje iz vode v sneg. Zaradi tega se sprosti ti. latentna toplota, ki porablja energijo tako, da ne pride do snega, če vodne kapljice niso dovolj podhlajene. Podhladijo pa se tako, da se jim podaljša pot mešanja z vodno meglico iz nukleatorja, ki je po naši patentni prijavi minimalna 1,3 metra.The fans are significantly stronger than known systems and push the water droplets out of the nozzles (outer perimeter) and the nebula from its center of formation much longer than existing systems. Therefore, water droplets become much cooler over this longer distance than existing systems and when contacted by a nucleoate nebula into a water mist atomization space (which acts as a crystallographic melt in cooling the melt or in the formation of cloud-dust particles, etc.) , and immediately change its state from water to snow. It makes you free. latent heat that consumes energy so that no snow falls when water droplets are not sufficiently sub-cooled. However, they are cooled down by extending the mixing path with a water mist from a nucleator, which, according to our patent application, is at least 1.3 meters.
Zato pri ostalih sistemih, kjer imajo vodne kapljice krajšo pot, ne pride do tolikšne podhladitve teh kapljic in zato morajo ti sistemi imeti nižjo temperaturo okolice, da lahko izdeluje sneg. Ta novi sistem, predložen v tej patentni prijavi, pa zaradi tega lahko deluje pri višjih temperaturah okolice, ker je seveda večen problem na smučiščih. Zaradi tega se ponavadi izdeluje sneg samo ponoči in če noč ni dovolj hladna, ni snega. S temi topovi, izdelanim po naši inovativni rešitvi, pa se po nam znanih dognanjih iz preizkusov na terenu lahko izdeluje sneg vsaj pri 30% višjih stopinjah oz. toplejšem ozračju, kot so zmožni nam poznani ostali snežni topovi. S testiranji smo dognali, da sneg lahko delamo pri -1,8° C, medtem ko ostali tega ne zmorejo prej kot recimo pri -2,6 0 C, kar je 30% razlike ali drugače, pri -5° C lahko izdelamo vsaj 30% več snega od konkurence s približno enako porabo energije in vode. Razlika je večja, ampak nekaj rezerve verjetno ne škodi.Therefore, for other systems where water droplets have a shorter path, these droplets do not cool down too much, and therefore these systems must have a lower ambient temperature in order to produce snow. However, this new system, presented in this patent application, can therefore operate at higher ambient temperatures, because of course it is an eternal problem in ski resorts. Because of this, snow is usually made only at night and if the night is not cold enough there is no snow. These cannons, made according to our innovative solution, can, according to our knowledge from field trials, produce snow at least 30% higher degrees or. warmer atmosphere than other known snow cannons are capable of. Testing has shown that snow can be worked at -1.8 ° C, while the rest can not do it earlier than, say, -2.6 0 C, which is 30% difference or otherwise, at -5 ° C we can produce at least 30% more snow than competitors with about the same energy and water consumption. The difference is bigger, but some of the reserve probably doesn't hurt.
Naš sistem ima prednost pred obstoječimi zato, ker lahko dela pri višjih temperaturah okolice, daje večjo količino snega, lahko ga nastavljamo poljubno (z vklopi/izklopi obročev s šobami za vodo), ni nastavljanja pritiska vode kot pri ostalih sistemih, kije zelo drago.Our system has an advantage over the existing ones because it can work at higher ambient temperatures, give more snow, can be adjusted arbitrarily (by turning on / off rings with water nozzles), there is no setting of water pressure than other systems, which is very expensive.
