Description
Technical field
The present invention relates to fire extinguishing equipment, and in particular to a kind of integral type fire extinguisher bomb jettison system of individual equipment and its jettisonings
Method.
Background technology
The current sylvosteppe fire extinguishing equipment status of China is not enough to the increasingly serious particularly serious sylvosteppe fire of support reply
Calamity is threatened.Existing fire extinguishing equipment is more based on manual work, and inefficiency is dangerous high.By taking fire extinguisher bomb as an example, individual soldier takes
With fire extinguisher bomb generally by the way of manually throw around the scene of a fire to casting inside the scene of a fire, limited by Human Stamina, this
Therefore fire-fighting efficiency is low for class fire extinguisher bomb light weight, throwing it is dangerous high and be difficult to quick control apart from immediate cause this operation
The intensity of a fire.
Thus expect a kind of high-effect fire-extinguishing bullet that can be carried by individual soldier and its jettison system, there can be larger matter
Amount, casting distance and higher fire-fighting efficiency farther out.
The content of the invention
For problem above, the present invention provides a kind of integral type fire extinguisher bomb jettison system of individual equipment and and its side of jettisoninging
Method, with storage, transport, transmitting integrated function, is launched using high and low pressure air chamber, can effectively solve efficiently going out for fire extinguisher bomb
Problem that is fiery and casting more at a distance.
It is an object of the present invention to propose a kind of integral type fire extinguisher bomb jettison system of individual equipment.
The integral type fire extinguisher bomb jettison system of the individual equipment of the present invention includes：Transmitter rack, fixing chuck plate, launching tube
And fire extinguisher bomb；Fire extinguisher bomb is sent out in assembling one in each launching tube；One or more launching tubes are arranged on transmitter rack；It is fixed
Clamp fixes launching tube with transmitter rack；Each launching tube is included after launching tube closure, launching tube placket, launching tube
