In the present embodiment, the high-voltage pulse water cannon has two sub-systems, comprises fast energy storage and dump energy recovery system and water cannon emission system, and the high-voltage pulse water cannon provides energy by accumulator 22.When fast energy storage and the work of dump energy recovery system, reversal valve 7 right electromagnet get electric, the right position of reversal valve, pressure oil enters the cavity of resorption that singly goes out rod oil cylinder 10, its epicoele oil pressure is entered the cavity of resorption of airdraulic actuator 13, the air of compressed gas fluid cylinder 13 epicoeles, when gas pressure surpassed the blowing pressure of safety valve 20, the Compressed Gas of airdraulic actuator 13 epicoeles was pressed in the accumulator 22.Then, reversal valve 7 right electromagnet dead electricity, the reversal valve meta, hydraulic pump 4 off-loads, plug-in mounting check valve 8 is opened, under the Action of Gravity Field that loads pouring weight, the hydraulic oil that singly goes out the cavity of resorption of rod oil cylinder 10 is got back to fuel tank, simultaneously, the hydraulic oil of airdraulic actuator 13 cavity of resorptions enters into the epicoele that singly goes out rod oil cylinder 10, and airdraulic actuator is by air cleaner 15, pneumatic shuttle valve 16 and inlet valve 14 epicoele with atmosphere inhaling air fluid cylinder 13, when the piston rod that singly goes out rod oil cylinder 10 is return when putting in place, approach switch 11 sends signal, reversal valve 7 right electromagnet is got electric, begins next accumulation of energy process.After the emission of high energy gas jet water cannon, the cavity of resorption of jetting cylinder 32 still has certain residual compression, and after high-pressure ball valve 31 was opened, the Compressed Gas of jetting cylinder 32 cavity of resorptions was through manually ball valve 17, shuttle valve 16 and inlet valve 14 enter the epicoele of airdraulic actuator 13, and promote quick oil return, thereby realize that energy reclaims.After singly going out rod oil cylinder 10 and airdraulic actuator 13 several reciprocating motions, the dump energy of jetting cylinder 32 cavity of resorptions reclaims and finishes, its piston drops to the bottom of cylinder body, in-cylinder pressure is lower than atmospheric pressure, no longer suck from the jetting cylinder when airdraulic actuator 13 is air-breathing again, but draw from atmosphere by shuttle valve 16 and air cleaner 15.Through behind the gas replenishment process to accumulator 22 repeatedly, when reaching the setting pressure of pressure switch 21, reversal valve 7 dead electricity, the pump off-load, thermal energy storage process finishes.After the long-term work, owing to can not arrive topmost when leaking the piston gas-pressing cause airdraulic actuator 13, open bi-bit bi-pass reversal valve 9 and carry out repairing.In addition, when the internal diameter of hydraulic cylinder 10 during greater than airdraulic actuator 13 internal diameter, pressurization is arranged, can make the pressure in the accumulator 22 be higher than oil supply pressure.
During the work of water cannon emission system, need open first manual ball valve 27, controller control high-pressure ball valve 29 and 30 successively open and close, the high energy gas of certain volume enters the cavity of resorption of jetting cylinder 32, the high energy gas pushing piston that expands rapidly moves upward, the water body of jetting cylinder epicoele is accelerated, and when piston accelerated motion finished, the high speed water body penetrated through the top gun tube.After emission was finished, water pump 36 was opened to conical vessel 33 interior water fillings, and after the water yield reached, water pump cut out.High-pressure ball valve 29 and 30 is by air impeller control, and control gas is provided through pressure-reducing valve 28 by accumulator 26.When the Pressure Drop in the accumulator 26 during to the threshold pression of pressure switch 25, the inflation warning light of accumulator 26 is opened, open manual ball valve 23, through gas safety valve 24, inflated to accumulator 26 by energy storage and recovery system, until upper limits pressure is when being increased to the upper limits pressure of pressure switch 25, the inflation of accumulator 26 finishes warning light opens, and closes manual ball valve 23.
The characteristic of very-long-range high-voltage pulse water cannon is:
1, very-long-range high-voltage pulse water cannon is the kinetic energy that the pressure energy of gas is converted into water body by the instantaneous burst of high energy gas, can obtain very large water velocity, and range can be improved largely than fire water monitor.
2, the efficient of very-long-range high-voltage pulse water cannon depends on gas energy storage process and water body emission process, and the emission process time is very of short duration, and energy loss is little, and dump energy is higher than the efficient of traditional water cannon after reclaiming.
3, very-long-range high-voltage pulse water cannon flow velocity only depend on high energy gas energy what, by control high energy gas volume regulate the water cannon flow velocity, Peak Flow Rate just is subject to the restriction of jetting cylinder stroke.
Although 4 very-long-range high-voltage pulse water cannon intermittent transmission current, consider higher than fire water monitor efficient, its output current mean power be higher than traditional water cannon.
When 5, reality was used, very-long-range high-voltage pulse water cannon then was not subjected to the impact of source pressure.
