[0001] Technical field

[0002] The invention 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.

[0003] Technology Level

[0004] Robotic devices (fire robots) for extinguishing fires in extreme conditions with the ability to be remotely controlled by operators from a safe distance are known [GOST 25686-85; Fire robot / / Civil Defense: Encyclopedia in 4 volumes. T. III (P - S) - M .: FGBU VNII GOChS (FC), 2015].

[0005] However, known fire robots are not efficient enough and have a number of technical shortcomings that limit their widespread industrial use.

[0006] The MT-LBu-GPM-10 tracked fire engine is known, based on the chassis of the MT-LBu multi-purpose tracked transporter-tractor, designed for a range of works in difficult conditions, which can be used both in the crew control mode and in the remote control mode for work in high-risk areas, and contains: water and foam tanks with a capacity of 3200 liters and 300 liters, respectively; a fire pump, a monitor nozzle (with remote control) with a range of a continuous water jet of at least 60 m, a filter and ventilation unit with a capacity of 200-220 m 3 / h; motor pumps; 2 course extinguishing nozzles and 10 nozzles for sprinkling the machine itself. The GPM-10 can be equipped with a grader-type bulldozer blade, a plow, swamp-going tracks, specialized portable fire-fighting equipment, and autonomous power sources. For movement on asphalt, the machine can be equipped with special rubber-metal shoes [http: / / muromteplovoz.ru / product / fire_gpm10.php - as of 17.05.2024].

[0007] A multifunctional robotic fire-extinguishing system (RKP) of the middle class (El-4) is known, which has a body mounted on a tracked self-propelled platform, with compartments for fire-fighting equipment, water-foam communications for delivering fire-extinguishing agents, and engineering weapons - a combined bulldozer blade with a built-in hydraulic grip (three-link manipulator arm) for clearing paths and a lift for water-foam fire-extinguishing equipment with a boom. The third link of the manipulator is provided for the installation of a mechanical grip 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].

[0008] The water-foam fire-extinguishing equipment compartment in the front of the RCP contains a hydraulic pump, hydraulic 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 hit a target at a distance of up to 55 m. A combination dozer blade with integrated hydraulic coverage is located at the front. The rear of the hull houses the power unit: a diesel engine, a multi-speed gearbox, hydraulic pumps and valves, and fuel and oil tanks. The steering control 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.

[0009] The RPC 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 operator 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 stops after 100 milliseconds.

[0010] The LUF 60® auxiliary fire extinguishing system for work in especially hazardous conditions is known (manufactured by RECHNER′S Löschsysteme GES.MBH, Austria) [https: / / fireman.club / statyi-polzovateley / pozharnye-robot-dymoudaleniya-i-tusheniya-pozhara-luf-60 / ?ysclid=lwak0oe0nc103189789 as of 05 / 17 / 2024].

[0011] 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 meters.

[0012] LUF 60® is equipped with a fan unit with a central connection head that can be fitted with 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 on-board pump unit (depending on the configuration). A mist of water is sprayed into the air flow 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 environment, and reduces smoke concentrations by settling aerosol particles and organizing the flow of gases from the combustion zone. In addition, when using a foam solution, it is possible to supply medium and low expansion foam directly into the protected volume of the room where the fire is occurring.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).

[0013] The disadvantages of the LUF 60® auxiliary fire extinguishing system - remote control up to 300 m - still requires the direct presence of a person (operator) near the LUF-60® auxiliary fire extinguishing system.

The robot is controlled using the control panel. Joysticks are used to move the robot forward, backward, and left or right. At a distance of 10 to 5 meters from the fire, extinguishing agent (water or foam) is applied through the hose line to the nozzle to cool the area in front of the moving robot. The monitor nozzle, using an actuator and a vertical nozzle lift bracket, directs a stream of extinguishing mixture toward the fire. In areas of heavy smoke or poor visibility, the operator uses a video monitoring system with a video feed camera and floodlights.
