Description
IZGUDROJUMA APRAKSTSDESCRIPTION OF THE INVENTION
[001] Izgudrojums attiecas uz optikas nozari, konkrētāk lāzertehnoloģijām, vēl konkrētāk, uz apkārtējās vides un dzīvo būtņu aizsardzību no lāzera stara.[001] The invention relates to the field of optics, more specifically to laser technologies, more specifically to the protection of the environment and living beings from the laser beam.
Zināmais tehnikas līmenisThe known state of the art
[002] Tiešs augstas enerģijas lāzera starojums var būt bīstams cilvēku un dzīvnieku veselībai, kā arī apkārtējai videi, tāpēc iekārtās, kas izmanto augstas enerģijas lāzerus, ir nepieciešami mehānismi, lai nodrošinātu lāzera stara drošu norobežošanu.[002] Direct high-energy laser radiation can be dangerous to human and animal health, as well as to the surrounding environment, so equipment using high-energy lasers requires mechanisms to ensure safe containment of the laser beam.
[003] Statiski esošiem lāzeriem, kas apstrādā nelielu laukumu, pietiek ar aizsargstikliem vai aizsargkorpusu. Šāds risinājums neder, ja lāzers atrodas kustībā vai ja nepieciešams apstrādāt lielu kustībā esošu objektu. Šāda vajadzība ir, piemēram, nezāļu ierobežošanas iekārtās, kas izmanto lāzera staru, un kur iekārta kustas vagu virzienā, un nepieciešams nodrošināt to, ka lāzera stars tiek absorbēts gadījumā, ja tas atstarojas no kāda uz zemes esoša priekšmeta.[003] For static lasers that treat a small area, protective glasses or a protective housing are sufficient. Such a solution is not suitable if the laser is in motion or if it is necessary to process a large moving object. Such a need exists, for example, in weed control equipment that uses a laser beam and where the equipment moves in the direction of the furrows, and it is necessary to ensure that the laser beam is absorbed in case it is reflected by an object on the ground.
[004] Problēma, kas tiek risināta - nodrošināt apkārt esošu objektu aizsardzību no lāzera stara tādās ierīcēs, kurās lāzers vai apstrādājamais objekts tiek pārvietoti, gadījumos, kad lāzers atstarojas no apstrādājamā objekta.[004] The problem to be solved is to provide protection of surrounding objects from the laser beam in such devices in which the laser or the object to be processed is moved, in cases where the laser reflects from the object to be processed.
Izgudrojuma mērķis un būtībaPurpose and essence of the invention
[005] Šajā patentā tiek aprakstīta tehnoloģija un iekārta, lai aizsargātu no lāzera stara.[005] This patent describes technology and equipment to protect against a laser beam.
[006] Lai nodrošinātu barjeru, kas aizsargā no lāzera stara, bet vienlaikus fiziski neietekmē apstrādājamo objektu tiek izmantota gāzē disperģētu daļiņu (aerosolu, dūmu u. tml.) plūsma. Disperģētās daļiņas var būt cietas vielas vai sīki šķidruma pilieni, piemēram, bet ne tikai, ar ultraskaņu disperģēts (atomizēts) ūdens; uzsildīta vai uzkarsēta minerāleļļa, glicerīns vai propilēnglikols, kas pārvērsti tvaikos. Disperģētu šķidrumu vai cietu daļiņu - aerosolu, dūmu, miglas u. tml. iegūšanai izmantojami tirgū esoši risinājumi, piemēram, ultraskaņas miglas iekārtas (atomaizeri), glicerīna dūmu mašīnas. Disperģētās daļiņas var tikt formētas aizkaru veidā (izmantojot lamināras plūsmas sprauslas), vai izmatotas turbulentas plūsmas veidā un ievadītas daļēji noslēgtā telpā - kanālā. Kā kanāls, piemēram, var tikt izmantots U veida kanāls), kura vaļējā garenass ir vērsta pret kustīgo objektu un abi gali ir pilnībā vai daļēji vaļēji. Pārējās iekārtās daļas vai nu pilnībā piekļaujas apstrādājamajam objektam, vai ir nosegtas tādā mērā, ka tikai caur kanālu iespējama lāzera stara izkļūšana no iekārtas. Kanāls tiek piepildīts ar gaisā vai citā gāzē disperģētām daļiņām, kuras izkliedē vai absorbē lāzera stara enerģiju tādā mērā, ka no ierīces izkļuvušais starojums nav kaitīgs apkārt esošajiem subjektiem vai objektiem.[006] To provide a barrier that protects from the laser beam, but at the same time does not physically affect the treated object, a flow of particles (aerosols, smoke, etc.) dispersed in the gas is used. The dispersed particles can be solids or tiny liquid droplets, such as, but not limited to, ultrasonically dispersed (atomized) water; warmed or heated mineral oil, glycerin or propylene glycol converted to vapor. Dispersed liquids or solid particles - aerosol, smoke, fog, etc. etc. available solutions on the market can be used for obtaining, for example, ultrasonic fog machines (atomizers), glycerin smoke machines. Dispersed particles can be formed in the form of curtains (using laminar flow nozzles), or used in the form of turbulent flow and introduced into a partially closed space - a channel. As a channel, for example, a U-shaped channel) can be used, the open long axis of which is directed towards the moving object and both ends are fully or partially open. In the rest of the equipment, the parts either completely adhere to the object to be processed, or are covered to such an extent that the laser beam can only escape from the equipment through the channel. The channel is filled with particles dispersed in air or another gas, which scatter or absorb the energy of the laser beam to such an extent that the radiation escaping from the device is not harmful to the surrounding subjects or objects.
Izgudrojuma īstenošanas piemēriExamples of implementation of the invention
[007] Izgudrojuma objekts ir ierīce aizsardzībai no lāzera stara, kas satur disperģētu daļiņu ģeneratoru un daļiņu plūsmu veidojošus elementus. Savukārt daļiņu plūsmas veidojošie elementi ir disperģētu daļiņu plūsmas vads, kas ar vienu tā galu ir savienots ar disperģētu daļiņu ģeneratoru un otrs tā gals ir savienots ar sprauslu tā, ka disperģētu daļiņu ģeneratorā ģenerētā disperģētu daļiņu plūsma pārvietojas pa plūsmas vadu uz sprauslu un ārā no tās.[007] The object of the invention is a device for protection from a laser beam, which contains a generator of dispersed particles and elements forming a flow of particles. On the other hand, the elements forming the particle flow are the dispersed particle flow line, which is connected with one end to the dispersed particle generator and the other end is connected to the nozzle, so that the dispersed particle flow generated in the dispersed particle generator moves along the flow line to the nozzle and out of it .
[008] Sprauslas atvērums var būt veidots dažādās modifikācijās, lai veidotu gan lineāru, gan turbulentu disperģētu daļiņu plūsmu. Tāpat sprauslas atvērums ir konfigurēts tā, lai veidotu disperģētu daļiņu plūsmas daļiņas ir ar diametru 15 mikrometri vai mazāk. Sprauslu atvērums ir konfigurējams ar lietpratējam zināmām fluīdu dinamikas metodēm.[008] The nozzle opening can be designed in various modifications to create both linear and turbulent flow of dispersed particles. Also, the nozzle opening is configured to form a stream of dispersed particles having a diameter of 15 micrometers or less. The nozzle opening is configurable by fluid dynamics techniques known to one skilled in the art.
[009] Ierīce satur kanālu, kurā izvietota sprausla vai sprauslas, kā rezultātā disperģēto daļiņu plūsma tiek ievadīta kanālā. Pašam kanālam tā garenvirzienā un visā tā garumā ir atvērums un šis atvērums piekļaujas apstrādājamam objektam, kas var būt augsne. Savukārt šī augsne var būt dažādas formas, piemēram, vagas formā. Bez tam minētā ierīce ir konfigurēta tā, lai pārvietotos attiecībā pret apstrādājamo objektu.[009] The device comprises a channel in which a nozzle or nozzles are arranged, as a result of which a stream of dispersed particles is introduced into the channel. The channel itself has an opening in its longitudinal direction and along its entire length, and this opening adjoins the object to be processed, which can be soil. In turn, this soil can be of different shapes, for example, in the form of a furrow. Furthermore, said device is configured to move relative to the object to be processed.

[012] 2. att. ilustrē vēl vienu no izgudrojuma realizācijas veidiem.[012] Fig. 2 illustrates another embodiment of the invention.
[013] 1. att. ilustrēta ierīce tās pretskatā un sānskatā. Ierīce satur kanālu (3), kas tiek izvietots virs apstrādājamā objekta (7), kas ir vaga, un kas aptver kultūraugus (6). Tādējādi tiek nodrošināta noslēgta vide kultūraugu (6) apstrādei un vides aizsardzībai no lāzera stara.[013] Fig. 1 illustrated device in its front and side views. The device comprises a channel (3) which is placed over the object to be processed (7), which is a furrow, and which covers the crops (6). Thus, a sealed environment is provided for processing crops (6) and protecting the environment from the laser beam.
[014] 2. att. ilustrē ierīci aizsardzībai no lāzera stara, kas satur disperģētu daļiņu ģeneratoru (1) un daļiņu plūsmu veidojošus elementus. Daļiņu plūsmas veidojošie elementi ir disperģētu daļiņu plūsmas vads (2), kas ar vienu tā galu ir savienots ar disperģētu daļiņu ģeneratoru (1) un otrs tā gals ir savienots ar sprauslu (4) tā, ka disperģētu daļiņu ģeneratorā (1) ģenerētā disperģētu daļiņu plūsma (5) pārvietojas pa plūsmas vadu (2) uz sprauslām (4) un ārā no tās. Disperģētu daļiņu plūsma caur sprauslām (4) nonāk kanālā (3), kas izvietots uz vagas (7) kultūraugu (6) apstrādei.[014] Fig. 2 illustrates a device for protection against a laser beam, which includes a dispersed particle generator (1) and particle flow forming elements. The particle flow-forming elements are a dispersed particle flow line (2), which is connected to a dispersed particle generator (1) at one end and a nozzle (4) at the other end, so that dispersed particles generated in the dispersed particle generator (1) the flow (5) moves through the flow line (2) to and from the nozzles (4). The flow of dispersed particles through the nozzles (4) enters the channel (3) located on the furrow (7) for processing crops (6).
[015] Vēl viens izgudrojuma realizācijas variants var būt sekojošs. No PMAA (polimetilmetakrilāta) tika izgatavots taisnstūra veida 50 cm garš, 20 cm plats un 5 cm augsts kanāls (3). Kanāla (3) gali un apakšējā skaldni ir atvērtas. Kanāla (3) augšējā daļā izveidots atvērums, pie kura tiek piestiprināts disperģētu daļiņu plūsmas vads (2) 3cm diametrā, kas savienots ar disperģētu daļiņu ģeneratoru (1), kas ir ūdens miglas ģenerators - ultraskaņas dispersijas iekārtas. Kanāls (3) tika piepildīts ar ūdens miglu un cauri kanālam (3) garenvirzienā tika raidīts lāzera stars ar viļņu garumu 445 nm un optisko jaudu 20 W. 35 cm attālumā no kanāla (3) sākuma lāzera stars tika pilnībā izkliedēts.[015] Another embodiment of the invention can be as follows. A rectangular channel 50 cm long, 20 cm wide and 5 cm high was made from PMAA (polymethyl methacrylate) (3). The ends of the channel (3) and the lower face are open. An opening is created in the upper part of the channel (3), to which a dispersed particle flow line (2) with a diameter of 3 cm is attached, which is connected to a dispersed particle generator (1), which is a water mist generator - ultrasonic dispersion equipment. The channel (3) was filled with water mist and a laser beam with a wavelength of 445 nm and an optical power of 20 W was sent through the channel (3) longitudinally. At a distance of 35 cm from the beginning of the channel (3), the laser beam was completely dispersed.
[016] Piemērā aprakstīto iekārtu var pievienot lāzerravēšanas iekārtai tādā veidā, ka kanāla (3) šaurākais gals vērsts vagas virzienā, apakšējās sānu malas piekļaujas augsnei un caur kanālu (3) virzās kultūraugu (6) rinda. Tādā veidā kultūraugi (6) netiek traumēti, bet gadījumā, ja no zemes atstarojas lāzera stars, tas tiek absorbēts aerosolā, ar kuru pildīts kanāls (3).[016] The device described in the example can be connected to the laser weeding device in such a way that the narrowest end of the channel (3) is directed towards the furrow, the lower side edges touch the soil and the row of crops (6) moves through the channel (3). In this way, the crops (6) are not injured, but if the laser beam is reflected from the ground, it is absorbed in the aerosol filled with the channel (3).
