An anti-tempering type drilled fire water gun

Abstract

The invention discloses an anti-tempering type drilled fire water gun, comprising: a bracket, handles are symmetrically arranged on the left and right sides, and a tripod is arranged below; a fixing sleeve is arranged in the middle of the bracket; a drilling pipe, the front end Drilling sawtooth is provided; the top fixing seat is slidingly connected with the drilling pipe through the top shaft sleeve, and the top sealing ring is provided at the front end; the sealing slide seat is nested inside the drilling pipe, and the front end is provided with a water gun nozzle. The invention can drill the space where explosion may occur through the drilling tube, and the outer side and the middle of the drilling tube are provided with corresponding sealing structures, which can ensure that the space remains sealed after drilling to prevent outside air from entering. There is a sealing sliding seat in the middle of the drilling pipe, and the sealing sliding seat can slide in the drilling pipe, thereby pushing the nozzle of the water gun from the drilling pipe into the confined space, so that the nozzle of the water nozzle can spray water in the confined space, thereby eliminating Explosion hazard.

Description

technical field [0001] The invention relates to fire-fighting equipment, in particular to an anti-backfire drilling type fire-fighting water gun. Background technique [0002] There is a very dangerous phenomenon at the fire scene. When a fire occurs in a confined space, because the space is relatively sealed and oxygen is insufficient, incomplete combustion will generally occur and a large amount of toxic, flammable and explosive gases such as carbon monoxide will be produced. However, due to insufficient oxygen, so These toxic, inflammable and explosive gases cannot be burned and consumed, and gradually accumulate in the confined space. At this time, if the doors and windows of the confined space are opened and a large amount of fresh air flows in, the large amount of toxic, inflammable and explosive gases in the confined space will instantly reach the deflagration point, causing Deflagration or even explosion, this is the backfire phenomenon, and it is very dangerous for ...

[0002] There is a very dangerous phenomenon at the fire scene. When a fire occurs in a confined space, because the space is relatively sealed and oxygen is insufficient, incomplete combustion will generally occur and a large amount of toxic, flammable and explosive gases such as carbon monoxide will be produced. However, due to insufficient oxygen, so These toxic, inflammable and explosive gases cannot be burned and consumed, and gradually accumulate in the confined space. At this time, if the doors and windows of the confined space are opened and a large amount of fresh air flows in, the large amount of toxic, inflammable and explosive gases in the confined space will instantly reach the deflagration point, causing Deflagration or even explosion, this is the backfire phenomenon, and it is very dangerous for firefighters to encounter this situation in the fire scene

The applicant finds that the existing fire-fighting equipment is difficult to cope with this kind of fire. In order to eliminate this danger, it is often necessary to extinguish the fire while keeping the space airtight, reduce the temperature of the space, and eliminate the open flame point, so that the flammable and explosive gas cannot reach the fire. ignited, but existing firefighting equipment cannot do this
