Abstract
The invention aims to provide a cluster bomb type bullet shooting-off device based on high-pressure gas. The cluster bomb type bullet launching device comprises a high-pressure gas bottle, a front lining board, a back lining board, a one-way valve, a shooting-off airbag, a back connector and a fixing guide pipe, wherein the back connector is connected with a fixing pipe through a gas-guide pipe joint; the high-pressure gas bottle and the one-way valve are connected and are mounted in the back connector; the front lining board is mounted outside the fixing pipe and coaxially assembled; the back lining board is mounted outside the back connector and is coaxially assembled; and the shooting-off airbag is connected with the one-way valve through the gas-guide pipe joint. The cluster bomb type bullet shooting-off device provided by the invention can put bullets into the overhead of a forest fire ground through aviation equipment such as a helicopter; and the bullets explode within a crown fire range through a control system, so that an ultrathin dry powder fire extinguishing agent is diffused within a crown fire ground around a bullet explosion point to put out fire.
Description
Technical field
What the present invention relates to is the fire plant in a kind of forest fire prevention and control field.
Background technology
Forest fire is a kind of serious worldwide natural calamity, has caused immeasurable loss to the mankind's resources and environment, and therefore forest extinguishing is the whole world mankind's a vital task.In forest fire prevention and control field, crown fire endangers maximum and is difficult to most put out a fire to save life and property, and often becomes the greatest factor that particularly serious forest fire leads to.
At present, a kind of shrapnel formula intelligent forest fire extinguishing bomb has been proposed at home.In the bullet of this bomb, ultra-fine dry powder extinguishing agent is housed, can be thrown into overhead, the forest scene of a fire by aircraft equipments such as helicopters.Make bullet drop into the implode of crown fire scope by control system, make ultra-fine dry powder extinguishing agent disperse in the bullet demolition point tree crown scene of a fire around, thereby reach the object of fire extinguishing.
In the intelligent forest fire extinguishing bomb course of work of shrapnel formula, how making bullet that female bullet carries be scattered in as requested the scene of a fire is the key that this advanced person's forest fire prevention and control equipment can be realized compacting, extinguishing forest fire.Therefore, design the good bullet catapult-launching gear of a kind of service behaviour and become a urgent task.
Summary of the invention
The object of the present invention is to provide the shrapnel bullet catapult-launching gear based on gases at high pressure for forest extinguishing.
The object of the present invention is achieved like this:
The present invention is based on the shrapnel bullet catapult-launching gear of gases at high pressure, it is characterized in that: comprise gas cylinder, anterior liner plate, rear portion liner plate, check valve, launch air bag, rear portion connector, A/C, rear portion connector is connected and fixed pipe by air duct fitting, gas cylinder is connected with check valve and is installed in the connector of rear portion, anterior liner plate is arranged on stationary pipes outside and coaxially assembling, rear portion liner plate is arranged on connector outside, rear portion and coaxially assembling, launches air bag and connects check valve by air duct fitting.
The present invention can also comprise:
1, described check valve comprises connected check valve valve body, check valve back seat and is arranged on Compress Spring, inner elements of check valve, electric detonator, the cumulative flexible linear shaped charge in the space that check valve valve body, check valve back seat be connected to form, electric detonator, cumulative flexible linear shaped charge, inner elements of check valve, Compress Spring are connected successively, and gas cylinder bottleneck stretches in check valve back seat.
2, the described air bag that launches has four.
3, also comprise anterior connector, anterior connector is connected and fixed conduit.
Advantage of the present invention is: the present invention can be thrown into overhead, the forest scene of a fire by aircraft equipments such as helicopters.Make bullet drop into the implode of crown fire scope by control system, make ultra-fine dry powder extinguishing agent disperse in the bullet demolition point tree crown scene of a fire around, thereby reach the object of fire extinguishing.

Fig. 2 is that catapult-launching gear air bag is full of the A-A view after gas;
Fig. 3 is gas cylinder, check valve and air duct fitting assembling full sectional view;
Fig. 4 is inner elements of check valve full sectional view.
Detailed description of the invention
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～4, catapult-launching gear is as shown in Figure 1 fixed on the axial location of forest fire extinguishing bomb magazine, by bolt, anterior connector 8, rear portion connector 1 is fixed with female bracket up and down that plays magazine.Before catapult-launching gear assembling, the compressed air of high pressure will be full of by check valve 4 in high-pressure mini gas cylinder 2.Anterior liner plate 6 and rear portion liner plate 3 coaxially assemble with A/C 10 and rear portion connector 1 respectively.Cross Recess Head Screw 15 plays restriction rear portion liner plate 3 position vertically and moves.4 are launched air bag 5, A/C 10 and check valve and are together by a threaded connection with the corresponding interface of air duct fitting 9 respectively.A/C 10 one end are threaded connection mode with air duct fitting 9 and are connected, and the other end is connected by bolt assembly 7 and anterior connector 8.As shown in Figure 3, rear portion connector 1 is connected by screw bolt 11 with check valve valve body 14.
Non-return air valve 4 is to be assembled by check valve valve body 14, check valve back seat 16, Compress Spring 18, inner elements of check valve 13, electric detonator 20 and cumulative flexible linear shaped charge 12.Between inner elements of check valve 13 and check valve valve body 14, sealed by O RunddichtringO 19.Between check valve valve body 14 and check valve back seat 16, sealed by seal washer 17.
The specific works mode of catapult-launching gear is as follows:
After intelligent forest fire-fighting bomb is thrown in, when arrival bullet launches standard, female control system that plays is sent instruction, and electric detonator 20 is ignited; The energy of its generation ignites the cumulative flexible linear shaped charge 12 being attached thereto, and produces high temperature, high-pressure spray combustion gas; Jet flow gas combustion along cutting into two parts as the place that in Fig. 4, B-B indicated, is communicated with inner elements of check valve 13 both sides inner elements of check valve 13; Gases at high pressure in high-pressure mini gas cylinder are filled with rapidly and are launched in air bag 5 by the through hole of inner elements of check valve 13 air duct fitting 9 of flowing through; Due to liner, the inhibition of anterior liner plate 6 and rear portion liner plate 3, launch the power that the instantaneous expansion of air bag 5 produces, adjacent with it bullet is launched away at a high speed, complete bullet ejecting function.
