Description
Technical field
The present invention relates to the peripheral clearance sealing leak stopping of Hydraulic and Hydro-Power Engineering table gate hole field, particularly a kind of water-stopping structure of mobile working gate and sealing device, the present invention is particularly useful for ship lift tail-bay mobile working gate.
Background technology
In Hydraulic and Hydro-Power Engineering, gate leaks and not only causes unnecessary water resource loss, and affects the working environment of gate, even causes building cavitation corrosion and gate vibration, threatens engineering safety, so all must be provided with antipriming at gate periphery.At present table gate hole great majority all adopt prepressing type rubber water-proof device, and prepressing type rubber water-proof device exist to gate gap bad adaptability, part easily leak, water shutoff rubber quick abrasion when sliding door, owing to adopting the shortcomings such as precompressed force of opening and closing is large.
For adapting to the variation of downstream river course water level, ship lift tail-bay service gate requires to move up and down easily, the sealing position of gate spatially changes like this, corresponding building position is unfixing, and this just has higher requirement technically to ship lift tail-bay service gate: when the work of (1) tail-bay gate, will accomplish that periphery is water-tight; (2), when downstream river course SEA LEVEL VARIATION, gate can move up and down fast.
Because elastomeric material has unique mechanical property: super-elasticity, volume invariability, produces creep etc. under load action.Elastomeric material is widely used in the sealing of various gate at present, and under the effect of being under pressure, watertight rubber material can produce distortion and reach the effect of closed gate peripheral clearance, thus water shutoff leak-stopping effectively.Hydraulic gate operation is both at home and abroad put into practice and is shown, in the time that gate often moves up and down, conventional water seal is poor to the compliance in gate gap, particularly in the larger situation of gate span, be easy to cause water leakage of gate, affect gate and normally use, destroy the working environment of gate periphery.
Have at present a kind of pressurized type water seal using on down-the-hole gate, the major advantage of this pressurized type water seal is good to the compliance in gate gap, when gate also can adapt to water shutoff on one side when gap is inhomogeneous.Owing to being subject to technical restriction, pressurized type sealing also exists some to ask in the use now: 1. telescopic sealing back pressure medium is water body, and compression system pipeline must be connected with gate external water source, affects the layout of operating gate system.2. this pressurized type water seal is shaped as frame on the whole, and pressurising water body internal communication must have four sealing dual faces when water sealing operation, otherwise can cause watertight rubber without retraining destruction overhanging and that cause pressurized type water seal.For the table gate hole that only has three sealing dual faces, also do not adopt the precedent of pressurized type water seal at present.
In December, 2008 for example " Sichuan hydroelectric generation " (the 27th 3 phases of volume supplementary issue) 106-108 page article " application of pressurized type water seal in two power stations, beach ", the use to the water-stopping method of pressurized type in down-the-hole gate is introduced.But the water seal that this pressurized type sealing form is used is shaped as frame, is arranged in the surrounding in spilled water hole, hole, cannot be used for the table gate hole that only has three sealing dual faces of the present invention, and pressurized type water seal especially wherein easily damages.
