Waterborne type fire extinguisher water spray gun

Abstract

The invention belongs to the technical field of fire extinguisher spray guns, and particularly provides a waterborne type fire extinguisher water spray gun. The spray gun comprises a spray gun body; two symmetrical balancing modules are arranged on the side wall of the spray gun body; the balancing modules are used for balancing the counter force on the spray gun; the balancing modules comprise fixed blocks; the fixed blocks are fixed on the side wall of the spray gun body; rectangular plates are rotatably installed on the fixed blocks; two limiting seats are arranged on the side wall of the spray gun body; the limiting seats are used for limiting the rotating angle of the rectangular plates; circular holes are formed in the centers of the rectangular plates; annular grooves are formed inthe positions of the circular holes; circular rings are rotatably installed on the positions of the annular grooves; and more than two blocking plates are equidistantly fixed on the outer rings of thecircular rings along the circumference. According to the spray gun, the counter force is provided by rotation of fan blades, so the backward force of the spray gun body is offset, the spray gun is used in a energy saving mode, and the practicability of the fire extinguisher is improved.

Description

technical field [0001] The invention belongs to the technical field of fire extinguisher spray guns, in particular to a water-based fire extinguisher water mist spray gun. Background technique [0002] The water-based fire extinguisher sprays the foam produced by the AFFF aqueous film-forming foam fire extinguishing agent and nitrogen on the surface of the fuel, and the water precipitated from the foam layer forms a water film on the surface of the fuel to isolate the combustibles from the air. It is suitable for extinguishing the initial fire of solid or non-water-soluble liquid, and the fire extinguisher that can extinguish the fire of live equipment. Widely used in oil fields, oil depots, ships, factories, shops and other places, it is the necessary fire-fighting equipment to prevent fires and protect people's lives and property. [0003] There are also some technical solutions about fire extinguisher spray guns in the prior art, such as a Chinese patent with application...

Problems solved by technology

[0003] There are also some technical solutions about fire extinguisher spray guns in the prior art, such as a Chinese patent with application number 2019203069238, which discloses a water-based fire extinguisher water mist spray gun, including a nozzle, the nozzle is fixedly connected to the connecting seat, The rear connection seat is provided with a rear thread, the rear connection seat is threaded to connect the threaded connection sleeve, the threaded connection sleeve is threaded to connect the front connection seat, the front connection seat is provided with a front thread corresponding to the threaded connection sleeve, and the front connection seat is far away from the rear connection seat One end of the gun head is fixedly connected to the gun head, and the end of the gun head away from the front connecting seat is fixedly connected to the fixing ring. The first fixing seat is coaxially arranged inside the gun head, and the first fixing seat is fixedly connected to the gun head through the first fixing rod. , the second fixed seat is coaxially provided with the second fixed seat in the fixed ring, the second fixed seat is fixedly connected with the fixed ring through the second fixed rod, and the rotating rod is connected between the first fixed seat and the second fixed seat, The outside of the rotating rod is fixedly connected to the rotating block, and the outside of the rotating rod is also fixedly connected to a plurality of atomizing devices. This patent can increase the spraying of water mist when the water mist is sprayed by setting the rotating block and the atomizing device. The speed and the effect of broken liquid droplets improve the fire extinguishing effect of the fire extinguisher, and the nozzle of the spray gun has a detachable function, which is convenient for maintenance and replacement of the nozzle of the spray gun, but the spray gun has a large recoil when the water mist is sprayed out. The user needs to use greater strength to hold the spray gun, and the user with less strength cannot operate the fire extinguisher well, so that the use of the fire extinguisher is limited
