Abstract

The utility model relates to a fire extinguishing gun which is a fire fighting device using solid matter to extinguish fire. Compressed air enters a gun barrel from a sleeve barrel arranged on the tail of the gun barrel, and a fire extinguishing bomb positioned at the front end of a plunger piston is sent out at a high speed through a through hole in the plunger piston. The fire extinguishing bomb reaches a high or far fire field which is difficult for people to approach, and automatically detonates to release a solid extinguishing agent in order to extinguish fire. The utility model has the advantages of simple structure and convenient operation, and is suitable for various fire fields.

Description

Fire-extinguishing gun

The utility model is about the fire plant with the solid extinguishing agent fire extinguishing.

Present employed solid fire-fighting device has plenty of the gas emission powdery extinguishing chemical that adopts ignition charge to produce, and it can not produce a large amount of gas launching in a large number in the powder extinguishing chemical, and certain limitation is arranged during dangerous again use.Also having with gases at high pressure is power, carries the shape pulvis that looses and sprays at a high speed from emission gun muzzle, adopts gas generator to utilize powder burning to produce gases at high pressure in addition, and the shape pulvis that will loose is ejected into the scene of a fire.The pulvis that said method is launched all is the shape that looses, so the height of impelling or distance are limited.

The purpose of this utility model is to provide a kind of fire extinguisher bomb that utilizes compressed air will carry solid extinguishing agent to be transmitted into the fire plant higher or scene of a fire far away.

Fire extinguishing big gun of the present utility model is the device that the fire extinguisher bomb of solid extinguishing agent is arranged in being used to launch, it is characterized in that: be provided with the gun barrel rear of through hole, a sleeve is equipped with in its outside, its inside is equipped with a plunger, through hole on this plunger cylinder is corresponding with through hole on the gun barrel, and the piston in plunger and the cylinder is connected.A coupled logical tube is arranged on the gun barrel.Gun barrel is connected with hydraulic cylinder on being fixed on its base in addition.Fire extinguishing big gun base can comprehensively turn round.

Critical piece of the present utility model is a transmitter, and it is made up of gun barrel, sleeve, a tube, cylinder, plunger etc.

Be provided with the preferably gun barrel rear of strip through-hole radially of some through holes, the sleeve that is connected with air accumulator is equipped with in its outside, its inside have one on the cylinder through hole and gun barrel on the corresponding plunger of through hole, an end of this plunger is that sealing De ， And links to each other with the piston rod of a cylinder.The two coaxial line of cylinder and gun barrel has a reciprocating piston in the cylinder, it is two that piston rod passes the gun barrel tail end, rotates when the linear reciprocating motion to prevent piston, thereby keeps the radially relative position of plunger that piston rod connected and gun barrel constant.The front end of plunger is equipped with fence or net, and it can make compressed air pass through smoothly, can prevent that again fire extinguisher bomb from entering in the plunger.Fire extinguisher bomb is to fall in the gun barrel the coupled logical tube from gun barrel, and its position just is in the plunger front end of non-emission state.When compressed air when the B mouth of cylinder enters, the piston promotion plunger that moves to the gun barrel direction moves in the same way, when the piston in the cylinder moves near the gun barrel tail end, propping up a tube internal orifice is sealed by plunger, and the through hole one, lucky and on the gun barrel of the through hole on the plunger is corresponding, the through hole that this moment, compressed air passed on gun barrel and the plunger in the sleeve enters in the plunger, and the fire extinguisher bomb transmitted at high speed that is in its front end is all the time gone out.

The transmitter of fire extinguishing big gun is controlled by handling hand control valve.Control valve is the twin columns plug valve, and three equidistant pores that are arranged in order along axis direction are promptly arranged on cylinder shape valve, and middle pore links to each other with air accumulator, and all the other two pores then link to each other with two pores on the cylinder respectively.A double plunger is arranged in the valve body, and distance can just be included two holes in the above-mentioned pore between two plungers.The valve gap that plunger rod passes an end stretches out valve body, all is provided with through hole on the valve gap at its two ends.When the pulling valve rod makes plunger be positioned at the left side of valve body, compressed air enters the space of two plungers from the middle pore that connects air accumulator, again from the left side pore to cylinder, if the left side pore links to each other with the A hole of cylinder, then the piston in the cylinder is pushed to and advances, transmitter then enters duty, and original gas then comes out in the B hole from the cylinder in the cylinder, discharges from the through hole on the valve gap through the right ports of control valve.To be positioned at when cutting down the body right side operation principle the same when plunger.

The utility model except that transmitter, the air compressor machine that matches with it, storage tank, hydraulic cylinder, rotating disk etc. in addition.Air compressor machine is stored in compressed air in the storage tank, for coupled cylinder, sleeve provide compressed air, is the power source of emission fire extinguisher bomb.The rear fulcrum of fire extinguishing big gun links to each other with the bearing on the chassis with hinge, and front fulcrum then links to each other with the hydraulic cylinder piston rod that is fixed on the bearing with hinge, by the elevation angle of flexible adjustment big gun when launching of piston in hydraulic cylinder bar.The said equipment all is fixed on the chassis, and the chassis is installed in motor vehicle Shang ， And and can comprehensively turns round, in order to adjust the orientation of big gun when launching.

The utility model is simple in structure, easy to use, can launch fire extinguisher bomb in succession, and it is penetrated the back and ignites automatically, and solid extinguishing agent scatters immediately and falls, and carries out to cover burning things which may cause a fire disaster, air is isolated to reach the purpose of fire extinguishing.It is applicable to the fire extinguishing in the inaccessible skyscraper of personnel and the scene of a fire far away, also is applicable to various types of scenes of a fire.

Utilize the example shown in the accompanying drawing, the utility model be described further:

Fig. 1 is an assembling schematic diagram of the present utility model.

Fig. 2 is a transmitter operation principle schematic diagram of the present utility model.

Fig. 3 is a control valve cutaway view of the present utility model.

In assembling schematic diagram shown in Figure 1, motor vehicle (5) is provided with can comprehensive rotating base (6), is fixed with air compressor machine (1) thereon and is attached thereto logical air accumulator (2), and it is that cylinder (8) and sleeve (4) provide 39.2～78.4 * 10 ⁴The compressed air of Pa.Transmitter be by the bearing on the base (15) and sleeve with hinged rear fulcrum and with hydraulic cylinder (3) two ends respectively with gun barrel (7), the front fulcrum of base hinge connection is fixed on the base.

On the schematic diagram of transmitter shown in Figure 2, at the gun barrel rear that is provided with some radially strip through-holes (16), the sleeve that is connected with air accumulator is equipped with in its outside, its inside have one on the cylinder strip through-hole and gun barrel on the corresponding plunger of strip through-hole (10), the tail end of this plunger seals, and front end is for being equipped with the opening of fence (13).Cylinder (8) is fixed on the gun barrel tail end, and the two is a coaxial line.There are (12) two piston rods of reciprocating piston (11) to pass the tail end that the gun barrel tail end is fixed in the plunger sealing in the cylinder.Fire extinguisher bomb (14) is to fall in the gun barrel the coupled logical tube (9) from gun barrel, and its position just is in the plunger front end of non-emission state.
