The utility model discloses the drainage arrangement at a kind of top cover of waterwheel room of pumped storage power station, including top cover and base, the top cover centre position offers through hole, the first drainpipe is offered on the top cover, the top cover two side ends offer angle, and the angle is provided with sieve aperture, the sieve aperture bottom is provided with the second drainpipe, first drainpipe and the second drainpipe bottom are communicated in connecting leg, and the connecting leg bottom right side is provided with discharge outlet, and the discharge outlet is arranged right below sump.Drainage arrangement at a kind of top cover of waterwheel room of pumped storage power station of the utility model, structure is novel, by setting two drainpipes to be used for draining, drainage efficiency is substantially increased, while the screen pack at the top of drainpipe can effectively filter silt, it is to avoid leak stopping, simultaneously U-shape structure is used in the middle of drainpipe, so that the waste gas of bottom will not overflow scattered, with very high practicality, it is adapted to be widely popularized.
Description
Technical field
The utility model is related to the draining dress at technical field of drainage, specially a kind of top cover of waterwheel room of pumped storage power station
Put.
Background technology
Existing top cover of waterwheel room of pumped storage power station free-draining all passes through the row on top cover of waterwheel room bottom and base
Water pipe is discharged in sump or collection gallery.Due to base and the rigidity requirement of top cover, draining bore is general all smaller, and
Drainpipe quantity is no more than two so that displacement very little.In actual motion, the drainpipe for being arranged on cap base is easy to
Impeded drainage is caused by foreign matters from being blocked, substantial amounts of percolating water can gather inside top cover, causes the draining pump frequent starting of top cover,
Longtime running, even unit chaser and water logging factory building can be caused during head cover drainage failure of pump, and the pipeline of draining is directly connected
Easily emit bad smell and come out by drainpipe after sump, long-time.
Utility model content
The purpose of this utility model is to provide the drainage arrangement at a kind of top cover of waterwheel room of pumped storage power station, to solve
The problem of being proposed in above-mentioned background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of top cover of waterwheel room of pumped storage power station
The drainage arrangement at place, including top cover and base, the top cover centre position offer and offer first row on through hole, the top cover
Water pipe, the top cover two side ends offer angle, and the angle is provided with sieve aperture, and the sieve aperture bottom is provided with the second drainpipe,
First drainpipe and the second drainpipe bottom are communicated in connecting leg, and the connecting leg bottom right side is provided with discharge outlet, the draining
Mouth is arranged right below sump.
It is preferred that, first drainpipe and second row water pipe end are equipped with screen pack.
It is preferred that, first drainpipe is symmetrical arranged on top cover, in the middle of first drainpipe and the second drainpipe
Position is U-shaped.
It is preferred that, provided with even hole at the top of the connecting leg.
It is preferred that, the diameter of the connecting leg is more than the diameter of the first drainpipe and the second drainpipe.
Compared with prior art, the beneficial effects of the utility model are：A kind of hydroenergy storage station waterwheel of the utility model
Drainage arrangement at ceiling lid, structure is novel, by setting two drainpipes to be used for draining, substantially increases drainage efficiency, because
Covering plate structure reason, second drainpipe is arranged on edge, while facilitating draining, will not also destroy the rigidity of base and top cover
It is required that, while the screen pack at the top of drainpipe can effectively filter silt, it is to avoid leak stopping, while using U-shaped in the middle of drainpipe
Structure so that the waste gas of bottom will not overflow scattered, with very high practicality, greatly improve a kind of hydroenergy storage station waterwheel
The use feature of drainage arrangement at ceiling lid, it is ensured that its using effect and utilization benefit, is adapted to be widely popularized.
