Abstract
A protective system to liquid/air bow wave includes a controllable damp, buffer device, bow wave blocking device, energy distribution channel or absorption room. The damp and buffer bring damp to impacting bow wave according to its force. Parts of energy is also absorbed by distribution channel or absorption room.
Description
One, technical field
The present invention relates to a kind of prevention air-flow, liquid stream strong shock wave is to some facility, and object causes the defence engineering of breaking-up.
Two, background technology
The blast that violent typhoon, war cause is when inshore, river, the generation of river territory, water can form the huge strong water impact wave of energy, may cause devastating loss to the facility on littoral limit, when taking place on land, the air blast of generation may cause facilities such as building to suffer serious breaking-up.For the loss that prevents strong current, air blast shock wave to cause, people adopt construction barrier protector to prevent.Because the energy of shock wave is big, the intensity of pre-preventing engineering is just required very high, volume, weight are big, and it is very big to build difficulty, and construction cost is very high, and particularly to the packaged type protective equipment, manufacture difficulty is bigger, and weight is big, and cost is higher, and functional reliability is lower.As the high-intensity protective door, it is big to remove volume, and weight is very heavy, and the manufacturing cost height is made, installed outside the difficulty, and the distortion that causes owing to the weight reason in the use makes its unlatching, closes difficulty, and becomes a serious problem in protection effect and application life etc.
Three, summary of the invention
The present invention is in order to solve the technical problem that exists in the background technology, provides a kind of liquid stream, air-flow strong shock wave are applied damping, attenuating shock wave, the new concept of the liquid strong shock wave defence that energy is broken the whole up into parts, the principle and the construction program of system of defense.
Technical solution of the present invention is: the kinetic energy of fluid is broken the whole up into parts, decompose and endergonic method by energy, reduce the kinetic energy that acts on the protector significantly, the active force of avoiding acting on the protector is excessive, and reduction is to the requirement of strength of protector, thereby alleviated weight, reduced manufacture difficulty and cost, can improve the reliability of protection effectively.
Now be that example describes with the protective door: this liquid strong shock system of defense, according to the defence capability requirement, by one or multi-channel damping, buffered gate and isolating and protecting door, the energy split channel of both sides or endergonic cavity volume are formed in front of the door.
The damping of above-mentioned liquid strong shock system of defense, buffered gate, it is the adjustable safety guard that on the arc door-plate, is provided with a plurality of controllable damping passages and a plurality of similar overflow valves, do the time spent at no shock wave, this damping, the controllable damping passage of buffered gate and adjustable limit resistance device are closed, work as damping, when buffered gate is hit, the long-pending unlatching of controllable damping passage through-flow section under the effect of impact force, because of damping action, the flow that passes through is reduced, act on damping, the buffered gate impingement flow on the area of effectively being obstructed, under the effect of reaction force, keep out impingement flow on the one hand; The split channel that makes fluid pass through both sides is on the one hand shunted, or absorbs energy by cavity volume.The power that acts on damping, the buffered gate is significantly reduced.Because the flow by damping, buffered gate reduces, and the energy that acts on the shock wave on the protective door of downstream is significantly reduced, reduce the requirement of strength of protective door, weight reduction improves functional reliability.By regulating the opening force and the opening degree of damp channel, can control the energy that is attenuated.By regulating the opening force of safety guard, the limit value of control damping, buffered gate resistance is protected positive safety and reliability.
The present invention has the following advantages:
1. can break the whole up into parts impact energy, act on respectively on damping, buffered gate and the protective door, make stressed the reducing on the single assembly.
2. the energy split channel of damping, buffered gate and protective door upstream or energy-absorbing cavity volume, can absorption portion impact energy, reduced stressed on damping, buffered gate and the protective door.
3. the damping force that damping, buffered gate produce can be controlled by the control cross-sectional flow area as required.
4. damping, buffered gate have safety protection function.
5. damping, buffered gate and protective door reduce the requirement of intensity, weight saving, and manufacture difficulty and manufacturing cost reduce.
6. install, maintenance difficulties is little.
7. gentlier be difficult for producing distortion, long service life because of weight when using.
8. the defence reliability improves.
Four, description of drawings
Accompanying drawing is principle of the present invention and structural representation.
Five, the specific embodiment
The present invention is provided with one the arc protective door before protected position of needs or facility; one or multi-channel arc damping, buffered gate are set before protective door; respectively be provided with one in protective door and damping, buffered gate both sides and certain angle arranged with fluid flow direction; gradually outwards, extend upward the energy split channel or the endergonic cavity that communicate with the external world, dredge, absorb impact energy.On damping, buffering door-plate, a plurality of controlled throttling damp channels and a plurality of adjustable safety guard are set, damping, attenuating shock wave, the restriction resistance is excessive, protection damping, buffered gate.
Referring to accompanying drawing, when strong liquid stream or air blast 1, when the position 15 of needs is impacted, at first run into damping, buffered gate 8, when impact kinetic energy acted on damping, buffered gate 8, segment fluid flow continued to push ahead by damp channel 7; Segment fluid flow is flushed on the effective damping area of damping, buffered gate 8, produce active force, the reaction force that the effective damping area of damping, buffered gate 8 produces produces fluid stream 2, damping on the one hand, decay are flowed, make 4,6 shuntings of fluid stream by split channel or energy-absorbing cavity volume 5 on the one hand, energy is absorbed.Can reduce to act on the impact force on damping, the buffered gate 8 effectively.The damping force that damping, buffered gate 8 produce can be controlled by the cross-sectional flow area of regulating damp channel 7.Safety guard 3 on damping, the buffered gate 8 is by adjustable spring or hydraulic control; when impact force when regulating power; safety guard 3 is closed; when impact force when regulating power; safety guard 3 is opened; fluid therefrom flows through, and the resistance of damping, buffered gate significantly subtracts, and guarantees the safety of damping, buffered gate 8.The fluid 9 that continues to push ahead through overdamp, buffered gate 8 because its kinetic energy of damping action significantly reduces, when impacting protective door 14, because protective door 14 is closed, has stopped fluid and has flowed, and makes to impact protective door 14 downstreams 15 and obtain protection.The reaction force that fluid impact produces to the protective door 14 makes fluid form fluid stream 10, stops that on the one hand fluid 9 flows, and makes fluid stream 11,12 flow to split channel or cavity 13 on the one hand, and energy is absorbed.Reduce to act on the impact force on the protective door 14 widely, can protect the safety in the reliable and downstream 15 of positive protective door 14.
