Description
Technical field
The present invention relates to water-stopping structure and the sealing device in the peripheral clearance sealing leak stopping of Hydraulic and Hydro-Power Engineering table gate hole field, particularly a kind of mobile working gate, 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 radial gate vibration, threatens engineering safety, so all must be provided with antipriming at gate periphery.Current table gate hole great majority all adopt prepressing type rubber water-proof device, and prepressing type rubber water-proof device exist gate gap bad adaptability, local are easily leaked, sliding door time water shutoff rubber quick abrasion, owing to adopting the shortcomings such as precompressed force of opening and closing is large.
For adapting to the change of downstream river course water level, ship lift tail-bay service gate requires to move up and down easily, the sealing position of such gate is spatially change, corresponding building position is not fixed, and this just has higher requirement technically to ship lift tail-bay service gate: will accomplish that periphery is water-tight during the work of (1) tail-bay gate; (2), during 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.Domestic and international hydraulic gate operative practice shows, when gate often moves up and down, the compliance of conventional water seal to gate gap is poor, 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 a kind of pressurized type water seal used on down-the-hole gate at present, the major advantage of this pressurized type water seal is good to the compliance in gate gap, also can adapt to water shutoff when gate gap is uneven.Owing to being subject to technical restriction, also there are some now and ask in pressurized type sealing: 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 in use.2. this pressurized type water seal is shaped as frame on the whole, and pressurising water body inside is communicated with, and must have four sealing dual faces during water sealing operation, otherwise watertight rubber can be caused overhanging and cause the destruction of pressurized type water seal without constraint.For the table gate hole only having three sealing dual faces, also do not adopt the precedent of pressurized type water seal at present.
Such as in December, 2008 " Sichuan hydroelectric generation " (the 27th volume supplementary issue 3 phase) 106-108 page article " application of pressurized type water seal in ERTAN Hydroelectric ProJect ", the use of water-stopping method in down-the-hole gate of pressurized type is introduced.But the water seal that this pressurized type sealing form uses is shaped as frame, is arranged in the surrounding in spilled water hole, hole, cannot be used for of the present inventionly only having in the table gate hole of three sealing dual faces, pressurized type water seal especially wherein easily damages.
