Fire fighting bomb cold launching engine

Abstract

The invention discloses a fire fighting bomb cold launching engine. The fire fighting bomb cold launching engine comprises a gas storage shell with the front end connected with the rear end of a firefighting bomb through a connecting lantern ring, a connecting outer sleeve connected to the rear end of the gas storage shell, and a sealing casing pipe rotationally arranged in the connecting outer sleeve. The front end of the gas storage shell is connected with a sealing plug through a sealing ring. A cylinder body is coaxially arranged in the sealing casing pipe through multiple evenly-distributed connecting rib plates. An opening piston is arranged in the cylinder body. The outer end of the piston is in sealing fit with a compressed gas release port of the sealing casing pipe, and a resetcompression spring is arranged between the end, located in the cylinder body, of the piston and the bottom of the cylinder body. A release mechanism used for releasing compressed air in the cylinder body is arranged at the rear end of the cylinder body. The release mechanism is started through an electric initiator connected to the rear end of the release mechanism.

Description

technical field [0001] The invention belongs to the field of fire bomb equipment, and in particular relates to a cold launching engine which uses nitrogen as a medium for launching fire bombs. Background technique [0002] At present, with the increase of high-rise buildings, high-rise fire extinguishing has become a major concern of people, and the fire truck aerial ladder can only extinguish fires below the 10th floor. To ensure that the fire extinguishing bomb is within the specified flight range and the warhead drops within the allowable range, this requires that the pressure vessel of the fire extinguishing bomb engine can withstand high pressure to provide high power. Regarding the management and transportation safety of pyrotechnics, the existing standard pressure vessels suitable for launching fire bombs cannot withstand the pressure required for launching them. Contents of the invention [0003] The object of the present invention is to address the above-mentione...

Problems solved by technology

[0002] At present, with the increase of high-rise buildings, high-rise fire extinguishing has become a major concern of people. However, fire truck ladders can only extinguish fires below 10 floors. To ensure that the fire extinguishing bomb is within the specified flight range and the warhead drops within the allowable range, this requires that the pressure vessel of the fire extinguishing bomb engine can withstand high pressure, thereby providing a large power. The management and transportation safety of pyrotechnics, the existing standard pressure vessel suitable for the launch of fire bombs, its withstand pressure cannot meet the launch requirements
