Abstract
The invention discloses a kind of fire extinguisher bomb jettison system of individual equipment and its methods of jettisoninging.The present invention uses, and fire extinguisher bomb is arranged in launching tube, and multiple launching tubes are mounted on transmitter rack, can once carry multiple fire extinguisher bomb, and explosive payload is the 2 times or more of existing weaponry and equipment, improves fire-fighting efficiency；Fire extinguisher bomb is remain stationary under the collective effect of installation positioning component, launching tube sealing cover and low pressure gas indoor gas；When gas pressure, which persistently increases, is more than pressure threshold, the indoor pressure of low pressure gas is higher than the sum of shearing force suffered by shearing force suffered by installation positioning component and launching tube sealing cover, and the pressure of gas pushes fire extinguisher bomb to emit out of launching tube by transmitting push plate；The present invention has storage transport transmitting integrated function, improves fire extinguisher bomb adaptability；Emitted using low-pressure chamber, there is bigger range and more accurate drop point, it is possible to increase put out the fire personnel and scene of a fire distance reduce the work risk for the personnel of putting out the fire.
Description
Technical field
The present invention relates to fire extinguishings to equip, and in particular to a kind of fire extinguisher bomb jettison system of individual equipment and its method of jettisoninging.
Background technique
The current sylvosteppe fire extinguishing equipment status in China, which is not enough to support, copes with increasingly serious particularly serious sylvosteppe fire
Calamity threatens.Existing fire extinguishing equipment is mostly based on manual work, inefficiency, and risk is high.By taking fire extinguisher bomb as an example, individual soldier is taken
The mode manually thrown is generallyd use with fire extinguisher bomb around the scene of a fire to casting inside the scene of a fire, is limited by Human Stamina, this
Therefore fire-fighting efficiency is low for class fire extinguisher bomb light weight, throwing high apart from immediate cause this operation risk and is difficult to quickly control
The intensity of a fire.
Thus it is expected that one kind can have biggish matter by the high-effect fire-extinguishing bullet and its jettison system that individual soldier carries
Amount, farther away casting distance and higher fire-fighting efficiency.
Summary of the invention
In view of the above problems, the present invention provides a kind of fire extinguisher bomb jettison system of individual equipment, there is storage, transport, hair
Integrated function is penetrated, is emitted using high and low pressure air chamber, can effectively solve the high-effect fire-extinguishing of fire extinguisher bomb and is cast more at a distance
Problem.
An object of the present invention is to provide a kind of fire extinguisher bomb jettison systems of individual equipment.
The fire extinguisher bomb jettison system of individual equipment of the invention includes: transmitter rack, fixing chuck plate, launching tube and fire extinguishing
Bullet；One hair fire extinguisher bomb of assembly in each launching tube；One or more launching tubes are mounted on transmitter rack；Fixing chuck plate will
