A fire truck fire water gun for quick thawing in winter

Abstract

The invention relates to the technical field of fire protection, and discloses a fire truck fire water gun for rapid thawing in winter, including a gun head, an ice-breaking assembly and a deceleration assembly, the outer wall of the gun head is movably connected to the ice-breaking assembly, and the inner wall of the ice-breaking assembly is movable The deceleration component is connected, press and shrink the telescopic box, and place it in the groove. The telescopic box is stretched by the spring, and the ice-breaking component is stuck in the groove. The ice-breaking component is fixed with the tip of the gun, and then the motor is turned on. The output shaft drives the first air pressure telescopic rod to rotate, so as to drive the cutter head to rotate, and pull the pull rod down, so as to drive the rotating block to move upward, so that the cutter head enters the inner wall of the gun head to perform ice-breaking work. After the ice-breaking is completed, it can be pulled upwards Pull the rod to drive the cutter head out of the inner cavity of the gun head, and turn the rotating rod to drive the elastic rope to wrap around the outer wall of the rotating rod, pull the telescopic box to shrink, and the ice breaking assembly can be removed to achieve rapid ice breaking without pouring water to melt the ice Effect.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire truck fire water nozzle for quick thawing in winter. Background technique [0002] The fire water gun is a water jet tool for fire extinguishing. When it is connected with a hose, it will spray dense and substantial water flow. It has the advantages of long range and large water volume. According to the different jet forms and characteristics, it can be divided into DC water guns, spray water guns, multi-water guns, etc. Among them, the commonly used water guns are direct current and spray water guns. When a fire occurs, the water gun is very important. [0003] When a fire breaks out, time is very precious, but in winter, or when a fire breaks out in some relatively cold areas, the fire-fighting water guns are easily blocked by ice, making it impossible to spray water, which greatly delays the fire. In general, hot water is used to impact the water gun when going...

Problems solved by technology

[0003] When a fire breaks out, time is very precious, but in winter, or when a fire breaks out in some relatively cold areas, the fire-fighting water guns are easily blocked by ice, making it impossible to spray water, which greatly delays the fire. In general, hot water is used to impact the water gun when going to the fire area, so that the melting time of the ice is too slow, and it is easy to freeze the water gun when fighting a fire in a severe cold area. Therefore, we have launched a fire truck fire water gun that can quickly thaw in winter, which can quickly break the ice and directly break the ice without external watering
