Five, detailed description of the invention
Gate pier is concrete structure, or reinforced concrete structure, or stone masonry structure etc., can ensure that the dutiful work of gate pier is for foundation; Gate floor is reinforced concrete structure, or concrete structure, or stone masonry structure etc., also can ensure that the dutiful work of gate pier is for foundation; Both sides gate pier and gate floor cast in situs, and water and build up a complete overall structure, to increase its stability; Gate pier height should be greater than or equal gate height, to ensure that safe operation is for foundation; Gate axle adopts the material such as stainless steel or alloy, and is fixed on gate pier by bearing, and gate axle requires enough strength and stiffness, ensures that gate axle does not produce any distortion; Hollow gate is the material such as cast steel or alloy steel, should have certain rigidity and intensity, carry out antirust treatment, is provided with vertical and horizontal dividing plate in hollow gate, to increase rigidity and the intensity of hollow gate.The visual stressed size of bearing adopts rolling bearing or sliding bearing or adopts hinged bearing, hollow gate freely can be rotated around gate axle, and carry out waterproofing work; Upper block, lower block should pour into an overall structure with gate pier, and guaranteed strength requirement; Between hollow gate and upper and lower block, between hollow gate and gate floor, be provided with bar shaped sealing, between the gate and gate pier of gate axle surrounding, be provided with zero " type sealing collar, leaks to prevent from producing during hollow closing gate, ensures normal retaining.
When the present invention works, when after the change of upland water amount, water level is changed, and the water pressure acted on like this on hollow gate also can change thereupon, under the acting in conjunction of hollow gate water gravity in upper water pressure and hollow gate, automatically can complete the opening and closing process of hollow gate:
When the upstream water yield is lower, now need retaining of closing the door, because its water level is certain value, the water at water source, upstream can freely enter hollow gate by inlet opening, in it air by draining (gas) hole discharge, the water level in hollow gate and upstream water level contour; Due to hollow gate under-filled certain water yield, the gross weight of hollow gate bottom is caused to be greater than the weight on top, therefore, bottom gate and water are greater than the clockwise moment of the generation on top to the anticlockwise moment that gate axle produces, hollow gate is closed condition, is conducive to retaining.
If upland water amount increases, water level raises, and due to the effect of inlet opening, makes the water level in hollow gate also rise to the water level identical with upstream water level, and the portion gas in hollow gate is discharged by being vented (water) hole; When upper pond level and hollow gate door top is contour or higher than hollow gate lock top time, equally, by the effect of inlet opening, can make to be full of water in hollow gate, gas is all discharged, the unnecessary water yield entering gate also can be discharged by exhaust (water) hole, can to keep in hollow gate water abrim always; Make the water yield on hollow gate axle top be increased to maximum like this, utilize this part water weight, increase accordingly the weight of the hollow gate in gate axle top, be more conducive to the unlatching of gate.Now, gate top, bottom just become one quantitatively to the torque difference that gate axle produces, and afterwards, the rotation of the hollow gate then complete water pressure by hollow gate upstream and downstream controls; Along with upland water amount increases further, when water level before gates is elevated to certain altitude, at hollow gate, in it under heavy and upper water pressure acting in conjunction of water, the moment (moment around gate axle) acting on hollow gate top is made to be greater than the moment (moment around gate axle) of bottom, hollow gate can be made to turn clockwise, hollow gate is opened automatically, and upland water can be sluiced by the channel downstream between hollow gate and gate floor and above hollow gate top; When upland water amount maintain a certain amount of no longer change time, hollow gate letdown flow is equal with upland water amount, and before hollow gate, water level keeps stable, then the aperture of hollow gate keeps stablizing; If upland water amount increases further, then before hollow gate, water level raises further, act on the hollow moment on gate top and the torque difference of bottom increases further, the aperture of hollow gate can increase further, letdown flow is increased further, if when upland water amount increase to a certain amount of no longer change time, before hollow gate, water level keeps stable, hollow gate letdown flow is equal with upland water amount, then the aperture of hollow gate keeps stable; After when coming that the water yield increases to a certain degree, before hollow gate, water level rises to certain altitude, hollow gate can all be opened, now, the bottom of hollow gate and upper block and the top contact of lower block, hollow gatage reaches maximum, discharge capacity is made to reach maximum, to complete the needs of flood discharge well.
When upland water amount reduces, before hollow gate, water level can decline thereupon, in gate axle top weight, gate, the torque difference of water weighs and upper water pressure acts on gate axle moment and bottom also reduces gradually, and the aperture of hollow gate is reduced, and letdown flow reduces; When upper pond level reduces further, act on the hollow moment on gate top and the torque difference of bottom reduces further, gate is rotated towards the direction of current upstream automatically, then the aperture of hollow gate can reduce automatically, thus reduces letdown flow; If when upland water amount be reduced to a certain amount of no longer change time, then before hollow gate, water level keeps stable, and hollow gate letdown flow is equal with upland water amount, and remains unchanged, then the aperture of hollow gate keeps stablizing; If the further reduction of upper pond level, when lower than hollow gate door top, the water level in hollow gate also declines thereupon, and the water on hollow gate top heavily reduces, cause and act on the hollow moment on gate top and the torque difference of bottom reduces fast, gatage reduces further; When upland water amount is reduced to a certain degree, before hollow gate water level decreasing to a certain extent time, the moment that then and upper water pressure heavy by water in gate axle bottom weight, gate acts on gate axle can be greater than the moment on top, the aperture of hollow gate is reduced, until close completely, complete the task that automatic barrier gate stores.
When after hollow closing gate, owing to being provided with sealing at hollow gate and between both sides gate pier, gate floor and upper and lower block, hollow gate can be kept water-tight.The retaining of hollow gate upstream can be retained preferably, so that emerging profit uses.
The hollow flap gate of waterpower self-control, relies on water level height change in upper pond level and gate, automatically controls its aperture size, have the following advantages:
(1) structure is simple, opens and closes, do not need special messenger to operate control without the need to outer power such as electromechanical equipments.It by upland water situation auto-control, has saving human and material resources completely, easy to use, feature, achieve unattended operation.
(2) can automatic regulating gate aperture accurately and timely.Along with the lifting of upper pond level, gate can open and close gradually, automatically, accurately, in time, completes sluicing and retaining process, makes letdown flow and the lock flow that comes maintain dynamic equilibrium, and retaining, sluicing, flood control safety are reliable.
(3) the hollow flap gate of waterpower self-control, can rotate nearly 90 °, has cut the supporting construction behind the door of current balanced wicket, substantially reduce resistance to water-flow, conveyance capacity is stronger, can make the smooth lockage of floating thing, be convenient to sand surfing erosion and deposition, guarantee flood discharge safety.
(4) the hollow flap gate door-plate of waterpower self-control is steel-slag sand, and structure is simple, and convenient making and transport, application life is short.
(5) compared with general hydraulic automatism turnover panel, open more flexible, solve hydraulic automatism turnover panel and often cannot open, the contradiction that impact sluices.
Innovative point of the present invention is:
1. entity gate design is become hollow gate;
2. utilize hollow gate middle water level to change and the water weight change of generation, as a part for gate opening/closing power, change and just utilize upper water pressure as the present situation of gate opening/closing power in the past, make the keying of gate more flexible, work more reliable.
This gate design principle is unique, no matter technically, or the aspect such as functional performance, all create qualitative leap.
