Description

Technical Field

[0001] This utility model relates to the field of vehicle fire extinguishing technology, specifically an automatic fire extinguishing device for trackless rubber-wheeled vehicles. Background Technology

[0002] Currently, the engines of explosion-proof trackless rubber-tired vehicles used in coal mines are relatively old, and during long-term operation, there are safety hazards such as high engine compartment temperature, aging on-board pipelines, and cracked wiring insulation, which can easily cause fire hazards. Since electrical and oil fires in explosion-proof trackless rubber-tired vehicles mostly occur during operation, personnel usually cannot detect the fire point in time. The flames spread extremely quickly and are relatively hidden. After the fire is discovered, it is difficult to extinguish the fire in the engine compartment in time by simply using a fire extinguisher. Moreover, once a fire occurs, it not only causes economic losses due to the insurance premiums of the trackless rubber-tired vehicle, but also threatens the personal safety of the driver, passengers, and rescue personnel. Therefore, this application proposes an automatic fire extinguishing device for trackless rubber-tired vehicles to solve the above problems. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-2As shown, this utility model provides a technical solution: an automatic fire extinguishing device for a trackless rubber-wheeled vehicle, including a fire extinguishing tank 1. A valve is installed at the opening of the fire extinguishing tank 1, and an audible and visual alarm 8 is also installed on the valve. The valve is connected to a delivery pipe 3, and the other end of the delivery pipe 3 is connected to a U-shaped pipe 4. The diameter of both the delivery pipe 3 and the U-shaped pipe 4 is 12mm. Multiple fire source detectors 5 are installed at intervals on the U-shaped pipe 4, and a number of nozzles 6 are also installed at intervals on the U-shaped pipe 4. The nozzles 6 are staggered, with a distance of 1.5m between them and the electrical equipment and oil-containing equipment of the explosion-proof trackless rubber-wheeled vehicle. A U-shaped pipe 4 is installed at the electrical equipment and oil-containing equipment of the explosion-proof trackless rubber-wheeled vehicle, with the nozzles 6 directly facing these areas. The fire extinguishing tank 1 is installed at the bottom of the vehicle via a mounting bracket 2, away from the electrical equipment and oil-containing equipment to prevent fire from affecting the normal operation of the fire extinguishing tank 1. A fire source detector 5 is used to monitor the fire source. After the fire source detector 5 detects a fire source, it sends a feedback to the trigger 7. The trigger 7 can quickly trigger the valve of the fire extinguishing tank, and extinguish the fire in the cooperation of the delivery pipe 3, U-shaped pipe 4 and multiple nozzles 6, so as to achieve timely fire extinguishing in the early stage of fire. At the same time, the audible and visual alarm 8 will emit an audible and visual alarm. The trigger 7 is installed on the outside of the fire extinguishing tank 1. The trigger 7 has automatic start, manual start and mechanical emergency start. In the automatic start mode, after the fire source detector 5 detects a fire source, it sends a feedback to the trigger 7. The trigger 7 can quickly trigger the valve of the fire extinguishing tank and control the opening and closing of the valve of the fire extinguishing tank 1. In the mechanical emergency mode, the valve of the fire extinguishing tank 1 is opened manually. The manual start mode of the trigger 7 is provided by the switch 9, which is installed in the cab of the trackless rubber-wheeled vehicle.
