Description
Technical field
The present invention relates to water exploding device, especially a kind of gases at high pressure emission water exploding device.
Background technology
The urbanization paces of China are being accelerated, and the high building of big and medium-sized cities more than 20 layers stands in great numbers, and the high-storey fire-fighting is key subjects.Now fire water monitor (rifle) performance of equipment is not enough, can only get to thirty or forty rice high, can't carry out effectively outside compacting, and during inside fire attack, brave fire fighter has paid larger injures and deaths cost.Therefore, China is in the urgent need to long-range large power fire water monitor.
The technological deficiency that existing long-range water cannon exists: range is shorter.
Summary of the invention
In order to overcome the shorter deficiency of range of existing high-voltage pulse water cannon, the invention provides the gases at high pressure emission water exploding device of the long gas-liquid buffering of a kind of range.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of gases at high pressure emission water exploding device of gas-liquid buffering, comprise and accelerate cylinder and cushion dashpot, described acceleration cylinder comprises cylinder body, accelerates the cylinder upper end cover, accelerates cylinder bottom end cover, piston and buffering ring, the upper end of described cylinder body is connected with acceleration cylinder upper end cover, the lower end of described cylinder body is connected with acceleration cylinder bottom end cover, described piston can be installed in the cylinder body up or down, and described buffering ring can be installed in the cylinder body up or down, and described acceleration cylinder upper end cover is connected with the cushion dashpot bottom end cover;
Described cushion dashpot comprises inner cylinder body, outer cylinder body, cushion dashpot upper end cover and cushion dashpot bottom end cover, described inner cylinder body is positioned at outer cylinder body, the cushion dashpot upper end cover is connected with the upper end of inner cylinder body, outer cylinder body respectively, and described cushion dashpot bottom end cover is connected with the lower end of inner cylinder body, outer cylinder body respectively; Described inner cylinder body, outer cylinder body, cushion dashpot upper end cover and cushion dashpot bottom end cover form circular cylinder, in the described circular cylinder annular piston is arranged, at least 3 piston rods are installed on the described annular piston, described piston rod stretches out and inserts and accelerate the cylinder from the cushion dashpot bottom end cover, the described piston rod buffering ring interior with accelerating cylinder is connected, be processed with cannelure on the upper surface of acceleration cylinder piston, the cross section of cannelure is inverted T shape, the outstanding structure of annular on the buffering ring and cannelure have clearance fit relationship, and the outstanding circumferential interval of the annular on the buffering ring 90 degree are opened 4 V-type grooves that length is different;
Dash cylinder bottom is connected with buffering ring is inboard, and insert in the centre bore of cushion dashpot on dash cylinder top.
Technical conceive of the present invention is: the high-voltage pulse water cannon utilizes gases at high pressure that the instant water of certain mass is accelerated to high speed, penetrates from gun tube and forms the water bullet, and the high speed water bullet has high kinetic energy, can reach the range than common water cannon several times.If during close together, the water bullet has very large destructive power.
The present invention the water body in a kind of high-voltage pulse water cannon accelerate and emitter, take high pressure air as power, the instant water transmitted at high speed of certain volume can be gone out.
Beneficial effect of the present invention is mainly manifested in: range is longer.
Description of drawings
Fig. 1 is the schematic diagram of the gases at high pressure emission water exploding device of gas-liquid buffering.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, a kind of gases at high pressure emission water exploding device of gas-liquid buffering, comprise and accelerate cylinder and cushion dashpot two parts, accelerating cylinder is comprised of cylinder body 2, acceleration cylinder upper end cover 5, acceleration cylinder bottom end cover 1, piston 3 and buffering ring 4, the circular cylinder that cushion dashpot is comprised of inner cylinder body 9, outer cylinder body 10, cushion dashpot upper end cover 8 and cushion dashpot bottom end cover 11, annular piston 7 is arranged in the cylinder, 3 piston rods 6 are installed on the piston 7, stretch out from cushion dashpot bottom end cover 11, insert to accelerate in the cylinder, be connected with buffering ring 4 in accelerating cylinder.Processed cannelure on the upper surface of acceleration cylinder piston 3, the cross section of cannelure is inverted T shape, and the outstanding structure of the annular on the buffering ring and cannelure have clearance fit relationship, and the outstanding circumferential interval of the annular on the buffering ring 90 degree are opened 4 V-type grooves that length is different.Be connected with dash cylinder 12 bottoms and buffering ring are inboard, can move with buffering ring, insert in the centre bore of cushion dashpot on dash cylinder 12 tops.
This device is vertically placed during work, accelerates cylinder bottom end cover 1 and is fixed on the frame, and the water that injects certain volume from top enters and accelerates to be filled with the gas of certain pressure in the cushion dashpot epicoele in the cylinder.During emission, the gases at high pressure of certain volume enter acceleration cylinder cavity of resorption from accelerating cylinder bottom end cover 1 centre bore, promote accelerating 3 moments of cylinder piston moves upward water body in the cylinder is accelerated, after acceleration cylinder piston 3 strikes on the buffering ring 4, the outstanding structure of annular on the buffering ring is inserted on the piston 3 in the cannelure, the outstanding different V-type groove of upper 4 length of the annular of water on buffering ring in the cannelure is extruded, along with the degree of depth of inserting increases, the V-type throttle orifice is reduced to 1 by 4, thereby reach good cushioning effect, the impact of accelerating cylinder piston 3 and buffering ring 4 can be absorbed, and destroying appears in the structure of avoiding accelerating cylinder piston 3.Then accelerating cylinder piston 3 together moves upward with buffering ring 4, gas in the cushion dashpot epicoele is compressed, cavity pressure rises, owing to accelerating cylinder cavity of resorption gas expansion, cavity pressure descends simultaneously, when accelerating cylinder cavity of resorption gas pressure less than cushion dashpot epicoele gas pressure, accelerating cylinder piston 3 slows down, the water body that promotes with accelerate cylinder piston 3 and separate, form the water bullet, penetrate this device through endoporus and the cushion dashpot endoporus of buffering ring 4.Reduce along with accelerating cylinder cavity of resorption gas pressure, and the increase of cushion dashpot epicoele gas pressure, after the dynamic balance on acceleration cylinder piston 3 and the cushion dashpot piston 7, accelerating cylinder piston 3 and stop, emission process finishes.After the pressed gas sucking-off of accelerating the cylinder cavity of resorption, buffering ring 4 is got back to extreme lower position under the promotion of cushion dashpot piston rod 6, accelerates cylinder piston 3 and also drop on the cylinder bottom section that accelerates behind injected water, prepares again emission.
