Background
The hydropower station is generally provided with a repair water collecting well and a leakage water collecting well, or the repair water collecting well and the leakage water collecting well are combined into a water collecting well, and each water collecting well is provided with a drainage pump. In the long-term operation process of the water collecting well, silt can gradually settle at the bottom of the well and deposit to form silt, so for a hydropower station with higher silt content, the water collecting well needs to be frequently overhauled and desilted, otherwise, a water inlet of a drainage pump of the water collecting well can be blocked to cause that a water pump cannot work or a motor is buried in the silt to cause that the heat dissipation effect is poor and the motor is overheated to burn out, the safe and stable operation of the drainage pump is seriously influenced, and the maintenance workload of hydropower station operators is greatly increased.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve the existing problems, the device for improving the operation reliability of the drainage pump of the water collecting well of the hydropower station is provided.
The utility model adopts the technical proposal that: the utility model provides an improve power station sump pit drain pump operational reliability's device which characterized in that: and a sludge scouring mechanism which can scour and disturb sludge at the bottom of the water collecting well through pressure water is arranged at the bottom of the water collecting well.
The silt scouring mechanism is provided with a circle of silt scouring water supply pipes which are pre-buried in the wall of the sump well, the silt scouring water supply pipes are connected with water supply pipelines, a plurality of silt scouring pipes are connected with the silt scouring water supply pipes, one ends of the silt scouring pipes are communicated with the silt scouring water supply pipes, and the other ends of the silt scouring pipes penetrate through the inner wall of the sump well and are exposed out of the sump well.
One end of the water supply pipeline is connected with the silt flushing water supply pipe, the other end of the water supply pipeline is connected with a water intake positioned outside the sump, and a valve, a pressure water pump, a check valve and a valve are sequentially arranged on the silt flushing water supply pipe from the water intake end to the other end.
The pressure water pump is electrically connected with a timing automatic/manual controller of the water pump.
The silt flushing pipes are alternately arranged in the length direction of the collecting well at intervals, and the silt flushing pipes are oppositely arranged in the width direction of the collecting well.
The utility model has the advantages that: the utility model discloses well flushing pipe takes the mode of sump pit length direction interval alternate arrangement and width direction symmetrical arrangement, take timing automatic control or manual control pressurization water pump start-up operation, the pressure water-washed brush disturbance sump pit bottom's silt behind the pressurization water pump pressurization, make the unable siltation of silt and finally discharge through the sump pit drain pump, the effectual unable work of water pump or the motor that leads to of sump pit drain pump water inlet jam are buried in the silt and lead to the not good problem that the radiating effect burns out appears in the motor overheat, very big improvement the operational reliability of sump pit drain pump.

In the figure: 1. a water intake; 2. a valve; 3. a pressurized water pump; 4. a check valve; 5. the water collecting well (6, flushing and silt water supply pipe; 7, flushing and silt pipe; 8, automatic/manual controller).
Detailed Description
The embodiment is a device for improving the operation reliability of a drainage pump of a water collecting well of a hydropower station, and a sludge scouring mechanism which can scour and disturb sludge at the bottom of the water collecting well through pressure water is arranged at the bottom of the water collecting well.
The sludge scouring mechanism in the embodiment is provided with a sludge scouring water supply pipe which is pre-embedded in the wall of the sump well and annularly surrounds the sump well for one circle, and the sludge scouring water supply pipe is connected with a water supply pipeline and a plurality of sludge scouring pipes facing the sump well.
In the embodiment, the inner end of a water supply pipeline is communicated with a silt flushing water supply pipeline, the outer end of the water supply pipeline is connected with a water intake, a valve, a pressure water pump, a check valve and a valve are sequentially arranged on the water supply pipeline from the outer end to the inner end of the water supply pipeline, and the pressure water pump is electrically connected with a timing automatic/manual controller of the water pump.
In the embodiment, one end of the silt flushing pipe is communicated with the silt flushing water supply pipe, and the other end of the silt flushing pipe penetrates through the inner wall of the water collecting well and is exposed out of the water collecting well. The silt flushing pipes are alternately arranged in the length direction of the water collecting well at intervals, and the silt flushing pipes are oppositely arranged in the width direction of the water collecting well.
The embodiment has two modes of timing automatic control and manual control, and the timing automatic erosion control mode is as follows: the timing automatic/manual controller of the water pump is set to be in a timing automatic control mode, a time interval is set, the pressurized water pump is controlled to start and operate in a timing mode, water flow is discharged through the silt flushing pipe after passing through the water intake, the valve, the pressurized water pump, the check valve, the valve and the silt flushing water supply pipe, and the silt at the bottom of the water collecting well is flushed and disturbed by the pressurized water flow so that the silt cannot be deposited. The time setting of the timing automatic/manual controller of the water pump can be adjusted according to the silt flushing effect. The manual erosion and deposition control mode is as follows: the timing automatic/manual controller of the water pump is set to be in a manual control mode, the operator of the hydropower station manually controls the pressurizing water pump to start and operate, water flow is discharged through the silt flushing pipe after passing through the water intake, the valve, the pressurizing water pump, the check valve, the valve and the silt flushing water supply pipe, and the pressurized water flow flushes and disturbs silt at the bottom of the water collecting well to prevent the silt from silting.
