Fig. 1 is the schematic diagram of pressure-air big gun.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
with reference to Fig. 1, a kind of super-pressure air bubble, comprise main air accumulator 19 and water cannon, described water cannon comprises big gun body 28, the bottom of described big gun body 28 is emission cavity, main air accumulator 19 is communicated with described emission cavity by emission valve 25, described super-pressure air bubble also comprises fuel tank 1, singly go out rod oil cylinder 10 and airdraulic actuator 12, the oil-out of described fuel tank 1 is by hydraulic pump 4, check valve 5 is connected with three position four-way directional control valve 7, the oil return opening of described fuel tank 1 is connected with three position four-way directional control valve 7 by overflow valve 6, described three position four-way directional control valve 7 is communicated with the rodless cavity that described single rod list goes out rod oil cylinder 10 by plug-in mounting check valve 8, in the described rod chamber that singly goes out rod oil cylinder 10, spring is set, piston rod stretches out the described rod chamber that singly goes out rod oil cylinder, described spring housing is contained on piston rod, the rod chamber that described single rod list goes out rod oil cylinder 10 is communicated with the fluid chamber of described airdraulic actuator 12, the air inlet/outlet of the air chamber of described airdraulic actuator 12 is by charge valve 17, pressure sensor 18 is connected with described main air accumulator 19, the air inlet/outlet of the air chamber of described airdraulic actuator 12 is connected with air filter with inlet valve 13 is connected simultaneously.
Further, the described rod chamber that singly goes out rod oil cylinder 10 is connected with bi-bit bi-pass reversal valve 8, and described bi-bit bi-pass reversal valve 8 is connected with described plug-in mounting check valve 9.
Described emission valve 257 is communicated with pressure-reducing valve 24, described pressure-reducing valve 24 is communicated with the import and export of additional air accumulator 22, and the import and export of described additional air accumulator 22 are communicated with the air inlet/outlet of the air chamber of described airdraulic actuator 12 by additional inflation valve 20, additonal pressure relay 21 simultaneously.
Hydraulic pump 4 is driven by motor 3, describedly singly goes out to install on rod oil cylinder 10 in order to detect the approach switch 11 of piston rod shift position, installation the first manual ball valve 15 on the pipeline between the air inlet/outlet of the air chamber of described airdraulic actuator 12 and charge valve 17; The second manual ball valve 23 is installed in the outlet of described main air accumulator 19.Additional inflation valve 20 is connected with the air inlet/outlet of the air chamber of airdraulic actuator 12 by the 3rd manual ball valve 16.Described gun tube 28 is arranged on gun carriage 26, and bottled water bullet 27 is positioned at described gun tube 28.
In the present embodiment, the pressure-air big gun has two sub-systems, comprises fast aeration system and water cannon emission system, and the pressure-air big gun provides energy by main air accumulator 19.During the fast aeration system works, the right electromagnet of reversal valve 7 gets electric, the right position of reversal valve, pressure oil enters the rodless cavity that singly goes out rod oil cylinder 10, its spring cavity oil pressure is entered the sap cavity of airdraulic actuator 12, the air of compressed gas fluid cylinder 12 air cavitys, when gas pressure surpassed the blowing pressure of charge valve 18, the Compressed Gas of airdraulic actuator 12 air cavitys was pressed in main air accumulator 19.Then, the right electromagnet dead electricity of reversal valve 7, the reversal valve meta, hydraulic pump 4 off-loads, plug-in mounting check valve 9 is opened, under spring-force driven dual, the hydraulic oil that singly goes out the sap cavity of rod oil cylinder 10 is got back to fuel tank, simultaneously, the hydraulic oil of airdraulic actuator 12 sap cavities enters into the spring cavity that singly goes out rod oil cylinder 10, and airdraulic actuator is by air cleaner 14 and inlet valve 13 air cavity with atmosphere inhaling air fluid cylinder 12, when the piston rod that singly goes out rod oil cylinder 10 is return when putting in place, approach switch 11 sends signal, the right electromagnet of reversal valve 7 is got electric, begins next accumulation of energy process.Singly go out after rod oil cylinder 10 and the several reciprocating motions of airdraulic actuator 12 after the gas replenishment process to main air accumulator 19, by pressure sensor 18 with pressure feedback to controller and setting pressure relatively, if consistent, reversal valve 7 dead electricity, the pump off-load, thermal energy storage process finishes.After long-term work, can not arrive when causing the piston gas-pressing of airdraulic actuator 12 due to leakage topmost, open bi-bit bi-pass reversal valve 8 and carry out repairing.In addition, during greater than airdraulic actuator 12 internal diameter, pressurization is arranged when the internal diameter of hydraulic cylinder 10, can make pressure in main air accumulator 19 higher than oil supply pressure.
The water cannon transmitter is comprised of gun tube and gun carriage, and the bore of gun tube should adapt to corresponding water bottle diameter.The bottled water bullet directly is placed in gun tube, can adopt the water dispenser water bottle of 20 liters or the cushion of 1.5 liters, and inner dress water namely becomes the water bullet.
During emission, need first open the second manual ball valve 23, controller is controlled 25 open and close of emission valve, and the high energy gas of certain volume enters the cavity of resorption of gun tube 28, and high energy gas expands rapidly and promotes the accelerated motion of water bullet, and accelerated motion finishes after water launches out gun tube.
Benefit is: the high-pressure gas pressure of utilization is high, can reach 20MPa, can make the bottled water bullet reach high muzzle velocity, has huge energy; Due to the convenient water bottle that obtains, be therefore easily to make the water bullet; Army and police adopt the huge advantage of this water bullet emission gun to be can not form the such shell fragment of conventional artillery, only can allow the Security Officer further near target to the surrounding water spray after bottle breaks, and strive for the valuable time for finishing the work.If use common explosive, obviously abnormally dangerous for the personnel that carry out hostage's rescue duty.In addition, this shell is higher in the efficient that punctures aspect the targets such as wall, door for coach or vehicle window.
