Description

Field of technology

The utility model relates to the field of fire extinguishing, to mobile robotic means of explosion and fire prevention, fire extinguishing, chemical protection and emergency rescue operations in areas of increased explosion and fire hazard associated with the risk of exposure of personnel to hazardous fire factors, emergency spills of liquefied natural and hydrocarbon gas (LPG and LNG), emergency chemically hazardous substances and radioactive materials.

State of the art

Mobile robotic devices (fire robots) are known for extinguishing fires in extreme conditions with the ability to be remotely controlled by operators from a safe distance [GOST 25686-85; Fire robot//Civil Defense: Encyclopedia in 4 volumes. Vol. III (P - S) - M.: FGBU VNII GOChS (FC), 2015].

However, known fire robots are not efficient enough and have a number of technical shortcomings that limit their widespread industrial use.

The MT-LBu-GPM-10 tracked fire engine, based on the MT-LBu multipurpose tracked transporter-tractor, is designed for a range of operations in difficult conditions. It can be used in both crew-controlled and remote-controlled modes for work in high-risk areas. It includes: water and foam tanks with a capacity of 3,200 liters and 300 liters, respectively; a fire pump, a remote-controlled monitor nozzle with a continuous water jet range of at least 60 m, a filter and ventilation unit with a capacity of 200-220 m3/h; motor pumps; 2 course extinguishing nozzles and 10 nozzles for sprinkling the vehicle itself. The GPM-10 can be equipped with a grader-type dozer blade, a plow, swamp-going tracks, specialized portable firefighting equipment, and a self-contained power source. For driving on asphalt, the machine can be equipped with special rubber-metal shoes [http://muromteplovoz.ru/product/fire_gpm10.php - as of May 17, 2024].

A mid-range multifunctional robotic firefighting system (RFS) (El-4) is known. It features a body mounted on a tracked self-propelled platform with compartments for firefighting equipment, water-foam lines for delivering extinguishing agents, and engineering equipment—a combination bulldozer blade with a built-in hydraulic grapple (a three-link manipulator arm) for clearing paths and a water-foam firefighting equipment lift with a boom. The third link of the manipulator is designed to accommodate a mechanical grapple and monitor nozzles. The RCP also contains a lighting mast with a spotlight [https://fireman.club/statyi-polzovateley/robototehnicheskie-kompleksyi-el-4-i-el-10-naznachenie-i-taktiko-tehnicheskie-harakteristiki/ - as of 17.05.2024].

The water-foam fire-extinguishing equipment compartment in the front of the RCV contains a hydraulic pump, hydraulic valves, and pneumatic valves. The water-foam fire-extinguishing system consists of a centrifugal water pump, connecting pipelines, and a remotely controlled monitor nozzle. The high-pressure pump-gun can engage a target at a distance of up to 55 meters. The front section houses a combination dozer blade with an integrated hydraulic system. The rear section houses the powertrain: a diesel engine, a multi-speed transmission, hydraulic pumps and valves, and fuel and oil tanks. The steering system is also located at the rear of the platform. The central section is designed to accommodate a water tank with a capacity of up to 1,500 liters and a foam concentrate tank with a capacity of up to 400 liters.

The RCP is controlled via radio from a safe distance of up to 1,500 m using remote control technology from a control vehicle, which can be located up to 2 km away (in open terrain) when controlled via radio. The remote control system consists of an onboard control unit and an operator console. The console is a standalone system and is designed to perform various operations (transmitting information, displaying data on a screen, taking various measurements, etc.). The system monitors the condition and operability of the system and, if any malfunction occurs, enters emergency shutdown mode. If a communication error (radio interference) occurs, the system shuts down after 100 milliseconds.

The LUF 60® auxiliary fire extinguishing system is known for work in particularly hazardous conditions (manufactured by RECHNER′S Löschsysteme GES.M.B.H., Austria) [https://fireman.club/statyi-polzovateley/pozharnye-robot-dymoudaleniya-i-tusheniya-pozhara-luf-60/?ysclid=lwak0oe0nc103189789 as of 17.05.2024].

The LUF 60® is a compact, mobile, remote-controlled system for extinguishing fires in road, pedestrian, and railway tunnels, subways, warehouses, and pipelines. The LUF 60® radio-controlled auxiliary fire extinguishing unit also features a backup manual control system in case of power failure. The maximum operating range when using the remote control is approximately 300 m.

The LUF 60® is equipped with a fan unit with a central connection head that can accommodate a fire nozzle with a water flow rate of 7-40 l/s and a spray range of 60 m, or a foam solution with a flow rate of up to 14 l/s and a foam delivery range of up to 35 m. Water-foam fire extinguishing agents are supplied by an onboard pump unit (depending on the configuration). A spray of water is delivered into the airflow—creating a water fog—by 360 nozzles at a pressure of 15-20 atmospheres from a stand-alone pump unit via a 40 mm hose line. This significantly reduces the temperature at the fire site and in the surrounding area, and reduces smoke concentration by settling aerosol particles and organizing the flow of gases from the combustion zone. Furthermore, when using a foam solution, medium- and low-expansion foam can be delivered directly to the protected volume of the fire area. Water cannons - wireless remote control with adjustable spray rate and pressure (http://www.hkfsd.qov.hk/images/equipment/fire/e_luf60.html or http://xn--80aahko3actfqcl9bzh.xn-p1ai/luf/luf60.html all - as of 05/25/14).

The disadvantages of the LUF 60® auxiliary fire extinguishing system are that remote control up to 300 m still requires the direct presence of a person (operator) near the LUF-60® auxiliary fire extinguishing system.
