In order to enable the bracket 1 to have the function of adjusting the fire angle of the fire extinguishing gun, the bracket 1 comprises a bottom plate 101 and an adjusting plate 102, the lower part of the adjusting plate 102 is hinged on two first sliding blocks 103 through a pin shaft, the two first sliding blocks 103 are both slidably clamped on corresponding first sliding rails 104, the two first sliding rails 104 are both connected on the bottom plate 101 through bolts, the front side and the rear side of the adjusting plate 102 are respectively provided with a horizontal first telescopic part 105 and an inclined second telescopic part 106, the first telescopic part 105 is used for driving the first sliding blocks 103 to horizontally slide, the second telescopic part 106 is used for driving the adjusting plate 102 to rotate, the bottom plate 101 is connected with two supporting plates 107 through bolts, a rotating sleeve 108 is hinged between the two supporting plates 107, the rotating sleeve 108 is sleeved on the gas storage tank 2, the lower end of the gas storage tank 2 is connected with a connecting seat 109 through bolts, the, in this embodiment, the connecting seat 109 is cylindrical and hollow, and each of the striking bases 6 is located in the inner cavity of the connecting seat 109.
The first telescopic piece 105 and the second telescopic piece 106 are controlled to act independently or act together, so that the adjusting plate 102 inclines, the connecting seat 109 slides along the adjusting plate 102 in the process that the adjusting plate 102 inclines, the air storage tank 2 slides axially along the rotating sleeve 108, the shooting angle of the gun barrel 4 changes, and the rotating sleeve 108 can play a role in supporting and guiding. For example, the extension of the first telescopic member 105 is independently adjusted, the inclination angle of the adjusting plate 102 is increased, the adjusting plate 102 pushes the gas storage tank 2 forwards in the rotating process, meanwhile, the connecting seat 109 slides upwards along the adjusting plate 102, and after the extension of the first telescopic member 105 is stopped, the included angle between the gun barrel 4 and the horizontal plane is reduced compared with the previous state. It is well within the reach of a person skilled in the art to control the first and second telescopic members 105, 106 to change the firing angle of the barrel 4 and will not be described in detail here.
In this embodiment, two second sliding blocks 8 are welded on the connecting seat 109, the two second sliding blocks 8 are slidably clamped on the corresponding second sliding rails 9, and the two first sliding rails 104 are connected to the adjusting plate 102 through bolts; the body of the first telescopic piece 105 is hinged on the bottom plate 101, the working end of the first telescopic piece 105 is hinged on the first connecting rod 10, and two ends of the first connecting rod 10 are respectively welded on the corresponding first sliding blocks 103; the body of the second telescopic member 106 is hinged on the bottom plate 101, the working end of the second telescopic member 106 is hinged on the second connecting rod 11, and both ends of the second connecting rod 11 are respectively welded on the vertical part of the adjusting plate 102. In the present embodiment, the first and second telescopic members 105, 106 are each provided as a hydraulic cylinder.
When the fire extinguishing gun is used for firing the bullet holder 5, the firing air nozzle 7 is communicated with the high-pressure gas cylinder through a pipeline, in order to facilitate the connection of the firing air nozzle 7 with the pipeline, a first avoidance hole 102-1 for avoiding the high-pressure gas pipe is formed in the adjusting plate 102, and a second avoidance hole 109-1 for avoiding the high-pressure gas pipe is formed in the connecting seat 109.
The action process of the invention is as follows:
first, the firing angle of the barrel 4 is changed by controlling the first telescopic member 105 and the second telescopic member 106, and the detailed operation process is not described again.
The bullet support 5 and the fire extinguishing bomb are sequentially filled into each gun barrel 4, the tail of the fire extinguishing bomb abuts against the bullet support 5, and it should be noted that the limit end of the limit part 12 is controlled to retract when the bullet support 5 is filled, so that the bullet support 5 is filled. High-pressure gas (filled with air or nitrogen) is filled into each independent closed chamber 201 through a high-pressure gas cylinder, and the gas filling is stopped when the high-pressure gas in the chamber 201 reaches a preset gas pressure.
This fire gun can realize the transmission of different situations to many pieces of fire extinguishing bomb:
the first situation, communicate every percussion air cock 7 to the high-pressure gas cylinder through the high-pressure gas pipe that leads to more, the high-pressure gas pipe that leads to is provided with a master control valve on the high-pressure gas pipe that leads to, close at once after opening the master valve, high-pressure gas rises every bullet support 5 propelling movement, when the lower extreme of bullet support 5 is higher than the lowest of gas-guard hole 5, the sealing washer on bullet support 5 has not played the sealing effect, barrel 4 and cavity 201 are in the connected state already, because of the effect of pressure differential, the high-pressure gas of cavity 201 rushes into barrel 4 through gas-guard hole 5 fast, high-pressure gas promotes bullet support 5 upward rapid movement, finally, many pieces of fire extinguishing bomb launch simultaneously, this kind of launch situation adapts to more and puts out the concentration of same fire point.
In the second situation, each percussion air tap 7 is communicated to the high-pressure gas cylinder through an independent high-pressure gas pipe, an independent control valve is arranged on each high-pressure gas pipe, the specific launching process is the same as that in the first situation, so that the fire extinguishing cannon can be independently and continuously launched, and after the fire extinguishing bomb is launched at every time, a fire fighter can properly adjust the launching angle according to the landing point of the fire extinguishing bomb.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
