Abstract
A hydraulic self control flap gate is a water retaining building which has simple structure, low cost, is convenient and reliable, can automatically regulate water level, and is more and more applied in hydraulic, municipal, environment protection and the like engineering. However, as the gate is more and more applied, some defects of the gate are gradually exposed: in particular when engineering facilities need to be refitted, the flap gate can only be overturned with the help of a manpower winch; synchronous overturning is difficult after a plurality of flap doors prefabricated with concrete are interlocked on the wide water surface, the structures are easy to be damaged and the operation danger is quite high. In addition, when the gate is automatically closed after hydraulic self control flood leakage, if impurities are clipped at the bottom of the gate, the gate cannot fully reset to retain water, which also needs manpower to pull apart and clean the impurities. Therefore, people are exploring to develop a hydraulic water power interactive control flap gate to solve these defects. The invention discloses a convenient and feasible control method for changing the hydraulic self control flap gate to be hydraulic water power interactive control which is developed based on the purpose. The method can conveniently realize hydraulic water power interactive control, not only prevents hydraulic oil cylinders of the prior art from being soaked in water which is very easy to produce defects of rust to machine parts, damaged sealing and water source pollution, but also prevents the oil cylinders from being easily hit by rolling stone and impurities during flood leakage which may produce deformation and failure.
Description
One, technical field
The present invention relates to the control method of the hydraulic water power interactive control of flap gate commonly used in a kind of modern water conservancy projects.
Two, the state of the art
Current, water resource is in short supply day by day, high drop water resource is closely exhausted, the development and use of low head water resource just are subject to people's attention, and because the field irrigation and the needs of beautifying the environment, a kind of hydraulic automatically-controlled shutter gate that is called movable dam body has obtained application widely all over the world.This hydraulic automatically-controlled shutter gate can be controlled opening and closing automatically by the waterpower of its water levels of upstream and downstream difference, than traditional dam body and manpower control water level, has saved a large amount of funds and operation cost.But, in use progressively exposed its some shortcomings.These deficiencies mainly are: 1, when this water conservancy projects need be cleared up and repair, can only winch gate by manpower, make its sluicing; 2, after gate is opened flood discharge, if at the bottom of having foreign material to be stuck in, can hinder the retaining that resets of plate-turning door, also must draw back with winch by manpower, can clear up.In order to address these problems, in recent years, people are exploring and are transforming this hydraulic automatically-controlled shutter gate as hydraulic pressure and water power interactive control, are promptly controlled automatically by waterpower when normally controlling flood retaining, and hydraulic control system need not start and work; And when the artificial control of needs, the then keying of the artificial regulating gate of primer fluid pressing system.Wherein a kind of comparatively ripe product is between the back of flap gate and Zhi Dun hydraulic jack to be set, and this oil cylinder provides oil sources and control by the pumping plant on the dam facing.This method maximum not enough be exactly during sluicing oil cylinder under water, parts may corrode and get rusty, and the thing piece that is mingled with in the flood during flood discharge may injure cylinder body by a crashing object, influence the operation and the sealing of oil cylinder, in case seal break-off, control was lost efficacy on the one hand, on the other hand can polluted source.Especially working as crack between a door and its frame has a small amount of water spray, and oil cylinder then can suffer erosion for a long time, influences the application life of hydraulic control system.Another kind of design scheme is to found a higher Zhi Dun in the upstream of plate-turning door, and the hill of lock gate hatch increased, between middle part of propping up hill and Zhi Dun, one hinged connecting rod is set, the top of propping up hill top and Zhi Dun at gate is provided with a hydraulic jack, next interim when flood, the impulse force of water strengthens, and gate is hinged around the centre is washed open flood discharge, and work as drawdown, then gate is closed under the effect of door gravitational moment; When the artificial regulating gate of needs, the primer fluid pressing system is handled oil cylinder, and hinged some pull-up sluices around the centre with gate.Though this method can solve the problem of oil cylinder immersion, but its type has bigger change than the door type of maturation, and involving many hydraulics theoretical questions need inquire into, and its gate is in the process of opening upset, its moment of resistance can constantly become greatly, and water resistance increases.Its practicality still needs practice test.
Three, goal of the invention and solution
The objective of the invention is to invent the simple and effective method that a kind of hydraulic automatically-controlled shutter gate that will have maturation now is changed into the flap gate of hydraulic water power interactive control.
Its solution is: former honest 5 is added to increase after growing to the size of tumbling entirely greater than flap gate to water (flow) direction build out column 4, hydraulic jack 3 is installed on top at column 4, the front end of hydraulic jack 3 piston rods connects lengthening push rod 2, push rod 2 is hinged with lever 1 (original connecting rod lengthening), the left end of lever 1 and the bottom-hinged of flap gate (identical with original position).When the artificial regulating gate of needs is opened, only need the epicoele fuel feeding of primer fluid pressing system to oil cylinder 3, promote the oil cylinder piston bar and move downward with lengthening push rod 2 levers 1, just gate can be dug, open flood discharge; When the needs closed shutter, then change the fuel feeding direction of oil cylinder, to the cavity of resorption fuel feeding of oil cylinder 3, the piston rod of oil cylinder 3 upwards spurs push rod 2 and lever 1, makes closing gate.As long as the reversal valve meta of control oil cylinder 3 is H type or y-function, promptly remain on its meta, the upper and lower cavity of oil cylinder is communicated with fuel tank, then when non-hydraulic control, has kept the action principle of former waterpower self-control.So just simply realized the control of shutter gate hydraulic and water power interactive.Avoided oil cylinder to soak work in water, the parts easy-to-rust, sealing was lost efficacy ahead of time and may contaminated environment.Simultaneously prevented that again oil cylinder may be subjected to the collision deformed damaged of foreign material when flood discharge.
Four, description of drawings
Accompanying drawing 1 is action principle of the present invention and essential structure figure.
Five, embodiment
The present invention increases with honest 5 prolongation of former flap gate and at its afterbody to form column 4, on the top of column 4 hydraulic jack 3 is installed, and the piston rod of hydraulic jack 3 is by lengthening push rod 2 connection lever 1, the left end of lever 1 and the lower hinge of flap gate.Its embodiment is: when needs hydraulic control lock gate hatch is opened, the control hydraulic system reversal valve is to hydraulic jack 3 epicoele fuel feeding, promoting its piston rod stretches out downwards, promote lengthening push rod 2 and lever 1 simultaneously, lever 1 is supported by the hinged point 7 in centre, its left end upwards prizes gate and tumbles around the hinged point 7 that props up on honest 5, and gate is opened.Otherwise then flap gate has been closed in hydraulic control.
When usual waterpower self-control, do not need the primer fluid pressing system, because the reversal valve of oil cylinder 3 is H type or Y type meta function, its piston upper and lower cavity is communicated with, and communicates with fuel tank, be in the free floating state, motion to flap gate does not have interference effect, and the effect that has just increased by a damped cylinder that has so more helps the operation stability of flap gate in the process of opening and closing, tumbling at lock gate hatch stops when static it to occur patting phenomenon, prolongs its application life.
