Description

SISTEM ZA GAŠENJE POŽAROV V PREDORIHFUNCTION SYSTEM IN THE Tunnels

Predmet izuma je gasilni sistem, zasnovan za gašenje požarov v cestnih predorih oziroma tunelih, ki hitro in učinkovito pogasi požar brez neposredne (fizične) udeležbe ljudi.The object of the invention is a fire extinguishing system designed to extinguish fires in road tunnels or tunnels, which quickly and effectively extinguishes a fire without direct (physical) human involvement.

Izum torej rešuje problem gašenja požara v cestnih predorih. Tehnični problem, ki ga rešuje, je, kako zasnovati gasilni sistem v predoru, ki bo začel gasiti požar takoj oziroma deloma ali v celoti avtomatsko, brez posredovanja ljudi. V tunelih po svetu so namreč požari zelo pogosti, do njih pa lahko pride zaradi več faktorjev, na primer zaradi okvar na vozilih ali nesreč.The invention therefore solves the problem of fire fighting in road tunnels. The technical problem he solves is how to design a fire extinguisher in a tunnel that will start extinguishing a fire immediately or partially or fully automatically, without human intervention. Tunnels around the world are very common and can be caused by several factors, such as vehicle breakdowns or accidents.

Raziskave s področja požarne varnosti so pokazale, da požar na vozilu hitro narašča prvih 5 do 10 minut. Ko vozilo zagori, trenutni sistemi v sodobnejših tunelih sami javijo dogodek, lahko pa ga javijo tudi očividci. Tako nadzorni center pošlje intervencijsko ekipo v akcijo z navodili, kje je požar. Ocenjeno je bilo, da od trenutka, ko reševalna ekipa prejme klic, do trenutka, ko prispe na prizorišče požara, lahko traja tudi do 1 ure, pri tem pa je v nevarnosti tudi sama ekipa. Z avtomatskim sistemom bi lahko rešili kar nekaj življenj in preprečili velike posledice po požaru na samem objektu, ki bi zahtevale sanacijo in dolgotrajno zaprtje predora.Fire safety research has shown that on-board fire increases rapidly for the first 5 to 10 minutes. When a vehicle is fired up, current systems in the more modern tunnels report the event themselves, and can be reported by eyewitnesses. In this way, the control center sends the intervention team into action with instructions on where the fire is. It has been estimated that from the moment a rescue team receives a call to the moment it arrives at the scene, it can take up to 1 hour, and the team itself is at risk. An automated system could save quite a few lives and prevent major consequences after a fire on the site itself, which would require the rehabilitation and long-term closure of the tunnel.

Obstoječe rešitve za reševanje problema požara v tunelu so različne, vendar pa gre za pasivne rešitve, kar pomeni, da požara ne gasijo samodejno. Omenimo naj hidrantno omrežje in gasilnike, ki omogočajo gašenje požara z vodo, vendar ga lahko uporabijo udeleženci v nesreči, ki se čutijo sposobne za njegovo uporabo. Javijalni sistemi (s senzorji in kamerami, ročni, točkovni, linijski), ki so nameščeni pred vstopom v predor, v predoru na vidnih mestih, na omaricah za klic v sili ob vhodih v prečno povezovalne rove pri dvocevnih predorih itd. Delujejo avtomatsko ali s pritiskom na gumb, ki javi alarm za požar in točno lokacijo operaterju v določenem nadzornem centru. Predori imajo tudi prezračevalne sisteme, ki usmerjajo tok gorenja, dovajajo svež zrak v predor za preskrbo z zrakom za udeležence med nesrečo. Pozivni tabloji in evakuacijske poti s prečnimi predori pa se uporabljajo za obveščanje in evakuacijo iz mesta požara in tako nimajo vpliva na potek požara.The existing solutions for solving the fire problem in the tunnel are different, but they are passive solutions, which means that they do not extinguish fires automatically. Mention should be made of the hydrant network and fire extinguishers that make it possible to extinguish a fire with water, but may be used by accident participants who feel capable of using it. Public address systems (with sensors and cameras, manual, point, line), installed before entering the tunnel, in the tunnel in conspicuous places, on emergency cabinets at the entrances to the transverse connecting tunnels for two-pipe tunnels, etc. They operate automatically or at the touch of a button that reports a fire alarm and the exact location to the operator at a designated control center. The tunnels also have ventilation systems that direct the flow of burning, supplying fresh air to the tunnel for supplying air to participants during an accident. Signboards and evacuation routes with transverse tunnels are used to inform and evacuate the fire site and thus have no effect on the course of the fire.

Obstajajo pa tudi nekateri neposredni sistemi oziroma izdelki v smislu gašenja požarov v predorih, a jih je zelo malo. Sistem RoboGat, izum pod patentno prijavo EP 1169092 še vedno ni povsem avtomatski in je odvisen od cevovoda za boj proti požaru. Na vsakih 20-30 m se mora povezati na šobo, prek katere pride do vode in je zato primeren le za krajše razdalje, kot so garaže.There are also some direct systems or products in terms of tunnel fires, but there are very few. The RoboGat system, the invention under patent application EP 1169092, is still not fully automatic and depends on a fire fighting pipeline. Every 20-30 m it must be connected to a nozzle through which water flows and is therefore only suitable for shorter distances such as garages.

Podoben izdelek je tudi t.i. HI-FOG - sistem gašenja z vodno meglo, proizvajalca Tyco iz Nemčije. To je sprinklerski sistem gašenja s čisto vodo, ki zahteva veliko šprinklerjev kot tudi velike količine vode, kjer se voda v primeru gašenja požara razprši na zelo drobne kapljice. Problem pri tem sistemu je povezan s količino vode, saj je potreben velik bazen vode, zanj pa bi pri cestnih predorih težko našli ustrezen prostor. To je tudi razlog zakaj omenjeni sistem ni nameščen v cestne predore. Poleg tega mora sistem vodne megle imeti za svoje defovanje visokotlačne črpalke, ki vodno meglo distribuirajo do šob, ki morajo biti nameščene v objektu. Zopet se pojavi prostorski problem - kam jih namestiti v predor.A similar product is also so-called. HI-FOG - Water Fog Extinguisher, manufactured by Tyco, Germany. This is a clean water sprinkler system that requires a lot of sprinklers as well as large quantities of water where water is dispersed in very small droplets in case of fire. The problem with this system is related to the amount of water, as a large pool of water is required and it would be difficult to find adequate space in road tunnels. This is also why this system is not installed in the road tunnels. In addition, the water mist system must have high pressure pumps to distribute the water mist to the nozzles that must be installed in the facility. Again, a spatial problem arises - where to place them in the tunnel.

Nasprotno od obstoječih rešitev izum po naši patentni prijavi ne potrebuje bazena z vodo in cevovoda in je zato od vseh najbolj primeren za predore.In contrast to existing solutions, the invention does not require a water basin and pipeline according to our patent application and is therefore most suitable for tunnels.

Podrobneje bo izum pojasnjen v nadaljevanju z opisom izvedbenega primera in predloženih risb, ki prikazujejo:The invention will be explained in more detail below with a description of an embodiment and drawings which show:

Sistem za gašenje požarov v predorih je zasnovan iz gasilnega vozila A oz. več le-teh, stropnega nosilca B, po katerem se vozila A premikajo, polnilne postaje, v katero je priključeno vozilo A in s tem vedno pripravljeno za delovanje. Vozilo je nameščeno v polnilni postaji, ki se nahaja v servisnem tunelu ali odstavni niši. Del sistema po izumu je tudi programska oprema za nadzor in delovanje gasilnega vozila A. Programska oprema je nameščena v nadzornem centru, ki se ne nahaja nujno v tunelu. S programsko opremo v nadzornem centru upravljajo dežurni operaterji, ki upravljajo tudi z ostalimi sistemi v predoru.The tunnel fire extinguishing system is designed from fire truck A or. several of them, the ceiling bracket B, which moves vehicles A, the charging station to which vehicle A is connected and thus always ready for operation. The vehicle is installed in a charging station located in a service tunnel or recessed alcove. Part of the system according to the invention is also software for the control and operation of fire truck A. The software is installed in a control center, not necessarily located in a tunnel. The software at the control center is managed by on-call operators, who also operate other systems in the tunnel.

Gasilno vozilo A je sestavljeno iz naslednjih nujnih delov: nosilnega ogrodja A2, rezervoarja za gasilo A3, jeklenke z dušikom A4, pršiinega topa A5, vodila s kolesi A6, pogonskega kolesa A7, vilice oz. ogrodja, na katero je pritrjeno pogonsko kolo A8, vzmeti, ki zagotavlja kontaktno silo na pogonskem kolesu A9, kamere z barvno sliko (RGB kamera) A10, termo kamere A11, kamere z barvno sliko, ki se nahaja zadaj A12, verižnega pogona za prenos energije z motorja na pogonsko kolo A13, baterije A14, komandne omare A15 in motorja A16.Fire extinguishing vehicle A consists of the following essential parts: support frame A2, fire extinguisher A3, cylinders with nitrogen A4, spray gun A5, wheel guides A6, drive wheels A7, forks or. frame to which A8 drive wheel is attached, springs providing contact force on A9 drive wheel, color image cameras (RGB camera) A10, thermal camera A11, color image cameras located behind A12, chain drive for transmission energy from A13 motorcycle, A14 battery, A15 control cabinet and A16 engine.

Ob požaru operater v centru aktivira najbližje vozilo A tistemu sektoqu, v katerem je požar, tu gre za polavtomatsko uporabo sistema, lahko pa vozilo deluje tudi avtonomno, popolnoma avtomatsko, ko se samo odpravi do mesta požara in s pomočjo termovizije. Termo kamera 11 zazna največjo termično obremenitev in to sporoča računalniškemu programu, ki kordinate žarišča požara javi upravljalskemu sklopu gasilnega topa A5 in ga usmerja v žarišče požara in pogasi ogenj. Vodila A6, po katerih se vozilo A prevaža so nameščena na vozilo A in se zapeljejo na stropni nosilec B, ki se fiksno nahaja na stropu predora. To omogoča najlažji dostop po tunelu v vsakem trenutku, ker ga ne ovirajo vozila cestnega prometa v predoru, ki se ob dogodku bodisi nepravilno razvrstijo, ali pa so zaradi udeležbe pri nesreči nesposobna za samostojno odmikanje intervencijski skupini. To je možno zaradi nizkega profila ogrodja A2, ki ga zavzema gasilno vozilo A. Tako je gibanje možno tudi nad obstoječo signalizacijo in ostalo infrastrukturo. Aktivacija oziroma postopek, da gasilno vozilo A preide iz servisnega tunefa ali odstavne niše z vodilom A6 na glavni stropni nosilec B. To traja približno 10s. Ko je vozilo A na stropnem nosilcu B, se lahko premika v obe smeri.In the event of a fire, the operator in the center activates the closest vehicle A to the secto in which the fire is located, this is a semi-automatic use of the system, but the vehicle can also operate autonomously, completely automatically when it only goes to the place of fire and with the help of thermal imaging. Thermal camera 11 detects the highest thermal load and communicates this to a computer program that reports the coordinates of the fire focus to the fire control unit A5 and directs it to the fire focus and extinguishes the fire. The A6 guides that transport vehicle A are mounted on vehicle A and driven onto the ceiling carrier B, which is fixed on the tunnel ceiling. This provides the easiest access through the tunnel at all times, because it is not obstructed by road vehicles in the tunnel, which are either incorrectly classified at the event or incapable of moving independently to the intervention team due to their participation in the accident. This is possible due to the low profile of the frame A2 occupied by fire truck A. Thus, movement is possible over existing signaling and other infrastructure. Activation or process for moving fire truck A from service tunnel or recessed alcove with guide A6 to main ceiling mount B. This takes about 10s. When vehicle A is on ceiling bracket B, it can move in either direction.

V nadzornem centru operater prevzame komande in pelje vozilo A na mesto požara.At the control center, the operator takes commands and drives vehicle A to the scene of the fire.

Njegova hitrost je približno 22m/s, tako lahko doseže točko požara, ki je odmaknjena 500 m v 22 s. Če upoštevamo še čas pospeševanja in ustavljanja, je skupen čas do prihoda na mesto približno 30 s. Vozilo A za pogon uporablja enosmerni elektro motor A16, ki ga napaja baterija A14 na krovu. Motor A16 ima takšno moč, da zadostuje za celotno težo vozilo A z gasilom v rezervoarju A3. Ker ima vozilo baterijo A14 na krovu, gibanje ni omejeno z napajalnim kabli. Tako tudi ni možnosti električnega udara oseb v bližini. Izbira baterije A14 zagotavlja delovanje vozila A za 4-5h, tako zagotovimo brezpogojno delovanje tudi v primerih daljših izpadov električne energije na polnilni postaji. Operater vozilo A vodi s pomočjo kamere A10 na prednjem in kamere A12 na zadnji strani vozila A. V primeru, da je tunel v dimu, je vodenje možno tudi preko termične kamere A11, s katero je požar jasno viden. Na mestu požara je vozilo A pripravljeno na gašenje v trenutku. Operater aktivira elektromagnetni ventil na jeklenki dušika A4, ki je sestavni del za gašenje. Dušik se uporablja kot potisni plin, ki iz rezervoarja z gasilom A3 iztiska gasilno sredstvo (to je lahko npr. BIOVERSAL, težka pena ali drugo ustrezno sredstvo, ki se uporablja za gašenje vozil). Tako tlak v rezervoarju s gasilnim sredstvom A3 doseže ustrezen tlak za gašenje, npr. 16 barov v 5 s. Gašenje poteka preko pršilnega topa A5, ki ga je možno vrteti 300° po obeh oseh preko krmilne ročice v nadzornem centru. Domet samega topa A5 je zadosten za pokrivanje širine največjih predorov. Domet nadzira premična šoba na koncu pršilnega topa A5 z regulacijo tlaka. Rezervoar A3 zadošča za gašenje večjih požarov, volumen rezervoarja s gasilom je izbran za zadostno količino gasilnega sredstva. Po končani intervenciji operater odpelje vozilo A nazaj v servisni predor ali odstavno nišo, kjer se avtomatsko priklopi na električno polnilno postajo. Na polnilni postaji se ob servisu napolni rezervoar A3 s gasilom, jeklenka A4 s dušikom in opravi popoln pregled vozila A. V primeru daljših predorov je mogoče uporabiti tudi vozila A, ki so v osnovi namenjena za gašenje na drugih delih. Glede na izračune je optimalno število vozil A v predoru eno vozilo A na 1 km. Primer: v 2 km dolg predor namestimo 2 vozili A. Vsako od njiju pokriva 1 km in sicer po 500 m na vsako stran. S tem zagotovimo dovolj veliko odzivnost in preprečitev večje škode ob požaru v predoru. Možno pa je glede na zahteve in potrebe naročnika postaviti večje ali manjše število vozil A na km predora.Its speed is approximately 22m / s, so it can reach a fire point 500 m away in 22 s. Taking into account the acceleration and stopping time, the total time to arrival is approximately 30 s. Vehicle A is powered by a direct current A16 electric motor powered by an onboard A14 battery. The A16 engine has such power that it is sufficient for the total weight of vehicle A with the fire extinguisher in tank A3. As the vehicle has an A14 battery on board, movement is not limited by power cords. There is also no possibility of electrocution by persons nearby. Choosing the A14 battery ensures that the vehicle A operates for 4-5 hours, thus ensuring unconditional operation even in the event of prolonged power outages at the charging station. Operator A guides vehicle A with the camera A10 on the front and camera A12 on the back of vehicle A. If the tunnel is in smoke, guidance is also possible through the thermal camera A11, which makes the fire clearly visible. At the point of fire, vehicle A is ready to be extinguished in an instant. The operator activates the solenoid valve on the A4 nitrogen cylinder which is an extinguishing component. Nitrogen is used as a propellant to expel a extinguishing agent from the A3 extinguisher tank (this may be eg BIOVERSAL, heavy foam or other suitable extinguishing agent). Thus, the pressure in the tank with extinguishing agent A3 reaches the corresponding extinguishing pressure, e.g. 16 bars in 5 sec. The fire is extinguished via the spray gun A5, which can be rotated 300 ° on both axes via the control lever in the control center. The range of the A5 cannon itself is sufficient to cover the width of the largest tunnels. The range is controlled by a movable nozzle at the end of the A5 spray gun with pressure control. Tank A3 is sufficient to extinguish major fires, and the volume of the fire tank is selected for a sufficient amount of extinguishing agent. Upon completion of the intervention, the operator takes vehicle A back to the service tunnel or recess niche, where it automatically connects to the electrical charging station. At the filling station, the service tank is filled with a fire extinguisher A3, an A4 cylinder with nitrogen and a full inspection of vehicle A. In the case of longer tunnels, vehicles A, which are basically intended for extinguishing other parts, can also be used. According to the calculations, the optimal number of vehicles A in the tunnel is one vehicle A per 1 km. Example: 2 vehicles are installed in a 2 km long tunnel. Each covers 1 km, 500 m each side. This ensures a sufficiently high responsiveness and avoids major damage in the tunnel fire. However, depending on the requirements and needs of the client, a larger or smaller number of A vehicles per km of tunnel can be erected.

Podajmo še konkreten primer uporabe sistema. Na 2,8 km predora je zaradi okvare motorja na voznem pasu obtičalo vozilo. Zaradi neprevidnosti ga je prepozno opazil voznik tovornega vozila, ter trčil v zadnji del stoječega vozila. Zaradi prekratke varnostne razdalje je vanj trčilo še eno tovorno vozilo, ki se je v trenutku vnelo. Detektorji požara, nameščeni v tunelu, so v nadzorni center javili dogodek. Operaterje vklopil nadzorno kamero sektorja in se prepričal o dejanskem stanju v predoru. Aktiviral je reševalce, sam pa za intervencijo izbral vozilo A št.Let's give a concrete example of using the system. 2.8 km of the tunnel caused the vehicle to collapse due to engine failure. Due to carelessness, the driver of the truck was too late to see him and collided with the rear of the standing vehicle. Due to too short a safety distance, another truck collided with it, which instantly caught fire. The fire detectors installed in the tunnel reported the incident to the control center. Operators turned on the surveillance camera of the sector and made sure of the actual state of the tunnel. He activated the ambulances and selected vehicle A no.

3, ki pokriva sektor med drugim in 3 km tunela. Na nadzornem panelu je torej izbral vozilo št. 3, ter prevzel ročno upravljanje konkretnega vozila A. Vozilo A je v 25 sekundah na mestu3, covering the sector, inter alia, and the 3 km tunnel. He therefore selected vehicle no. 3, and took over the manual control of specific vehicle A. Vehicle A is in place in 25 seconds

dogodka in pripravljeno za delovanje. Ker je zaradi dima otežena vidljivost, mu pri gašenju pomaga termovizija (prek kamere A11). Prek teh podatkov lahko gasilni top A5 usmeri v žarišče požara. Aktivira aktivacijsko jeklenko z dušikom A4. Le-ta je prek reducimega ventila in gibljive cevi, ki sta sestavni del jeklenke A4, povezana z rezervoarjem za gasilo A3. Gasilo pod tfakom začne iztekati prek gasilnega topa A5 do mesta požara. Požarje po 30 sekundah pogašen. Po končani akciji operater nadzoruje mesto dogodka s termovizijo (kamera A11) do situacije, ko je mesto dogodka moč nadzorovati z video nadzornim sistemom. Z nadzorom z višine ima večjo preglednost in lažje usmerja intervencijsko skupino do poškodovanih. Ko je situacija pod nadzorom, vrne vozilo A na njegovo osnovno mesto. Aktivira servisno službo, da pregleda stanje vozila A, ki postori vse potrebno, da je vozilo A pripravljeno za morebitno novo intervencijo.event and ready to go. Because smoke makes it difficult to see, it is assisted by thermal imaging (via A11 camera) when extinguished. Through this information, the A5 fire extinguisher can direct the fire. Activates the activation cylinder with A4 nitrogen. It is connected to the A3 extinguisher tank via a reducer valve and a flexible hose, which are an integral part of the A4 cylinder. The fire extinguisher begins to escape through the A5 fire cannon to the fire point. Fires extinguished after 30 seconds. Upon completion of the action, the operator controls the event site by thermal imaging (camera A11) until the situation where the event location can be controlled by a video surveillance system. With height control, it has greater transparency and easier steering of the intervention team towards the injured. When the situation is under control, it returns vehicle A to its original location. It activates a customer service department to inspect the condition of Vehicle A, which makes sure that Vehicle A is ready for any new intervention.
