Telescopic protective spray head for vehicle fire extinguishing

Abstract

The invention discloses a telescopic protective spray head for vehicle fire extinguishing. The telescopic protective spray head comprises a spray head body, a guide rod, a reset spring, a fixing plate and a nozzle cover plate. A through hole is formed in the center of the fixing plate, and the fixing plate is arranged on the outer surface of the nozzle end of the spray head in a sleeving mode and tightly pressed on a shaft shoulder arranged in the middle of the spray head. The nozzle cover plate is arranged above a nozzle of the nozzle, and the other end of the nozzle is connected with an external fire extinguishing system pipeline; more than two guide rod telescopic holes are formed in the periphery of the through hole in the center of the fixing plate, one guide rod penetrates through each guide rod telescopic hole, the external thread end of each guide rod is fixed after penetrating through the nozzle cover plate, a flange is arranged at the other end of each guide rod telescopic hole, and a reset spring is sleeved on the center shaft between the flange and the fixing plate; wherein the guide rod consists of a central shaft, and flanges and external threads which are arranged at two ends of the central shaft.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a telescopic protective nozzle for vehicle fire extinguishing. Background technique [0002] Nowadays, the use of motor vehicles in all aspects of society has become very common, and at the same time, how to deal with vehicle fires is becoming more and more important. When military and police vehicles are dealing with riots and performing urban combat tasks, they are often threatened by violent elements using weapons such as Molotov cocktails to attack vehicles. Civilian vehicles may also encounter problems such as engine / electric vehicle battery fires, spontaneous combustion of goods, and dangers in the vehicle. If the fire cannot be controlled in time, the loss will be very serious.

AI Technical Summary

Problems solved by technology

When military and police vehicles are dealing with riots and performing urban combat tasks, they are often threatened by violent elements using weapons such as Molotov cocktails to attack vehicles. Civilian vehicles may also encounter problems such as engine / electric vehicle battery fires, spontaneous combustion of goods, and dangers in the vehicle. If the fire cannot be controlled in time, the loss will be very serious

[0003] In order to ensure a wider coverage of the fire extinguishing agent, the nozzles of the fire extinguishing system often need to be higher than the installation plane by a large distance, but the vehicle is prone to scratches during the driving process; in bumpy road conditions, the occupants in the vehicle are also easily bumped by the nozzles ;It will cause both personal injury and nozzle damage

[0004] Sprinklers are key components in fire extinguishing systems. For motor vehicles, especially vehicles with harsh working environments, such as armored vehicles or off-road vehicles, the exposed sprinklers on the top and sides may be blocked by dust, gravel, muddy water and snow water. , which will make the sprinkler head unable to work normally, resulting in the failure of the fire extinguishing device
