A high-rise building fire monitor

Abstract

The invention belongs to the technical field of fire extinguishers, specifically a high-rise building fire extinguisher, which includes a gun body, a walking unit, a positioning unit and a gun barrel; the upper periphery of the gun barrel is provided with an air inlet pipe, and the air inlet pipe passes through a pipe and a valve It is connected with the pressure air source; the position of the gun barrel in the air inlet pipe is evenly distributed with a group of spirally arranged air inlet holes; the cannonball for fire extinguishing is installed in the described gun barrel, and a group of guide vanes are evenly distributed on the circumference of the tail of the cannonball; The invention uses a high-pressure air source to inflate the air intake pipe, and then the compressed air is sprayed into the barrel through the spiral air intake hole to push the shells to launch while blowing the guide vanes to increase the spin of the shells and further improve the running stability of the shells. Increase the predictability of the trajectory of the projectile, which in turn increases the accuracy of fire extinguishing when the projectile arrives at the intended location.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishers, in particular to a fire extinguisher for high-rise buildings. Background technique [0002] The fire extinguisher is composed of a special fire extinguishing bomb and a launching device. The special fire extinguishing bomb is launched to the fire site by the launching device, and then the dry powder fire extinguishing agent is sprayed by the explosion of the fire extinguishing bomb to achieve the effect of long-distance fire extinguishing. It is difficult to reach or approach fire lines, control and extinguish forest fires, but for the field of fire fighting in urban high-rise buildings, the scope of application of fire fighting is limited. [0003] There are also some technical solutions about fire extinguishers in the prior art. For example, a Chinese patent with an application number of 2019105070003 discloses an aerodynamic fire extinguisher facing high-rise buildings. In the cyli...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, the fire extinguishing bombs are launched by gunpowder in the prior art, and fixed-point projection fires are carried out to the fire point area where the high-rise building is difficult to reach quickly and safely, so that the dry powder is sprayed out after the shell hits the fire. However, due to the fire site environment Complex, flammable and explosive gas and dust are more, gunpowder launching shells is easy to cause accidental danger, when the conventional gas is launched, the shells fly unstable, and the hit rate is difficult to control. A fire monitor for high-rise buildings proposed by the present invention
