Problems solved by technology

[0004] 2. With the operation of the pump station, after the silt in the inlet pool reaches a certain level, the sedimentation speed will no longer be the same as that in the initial operation of the inlet pool, and the sedimentation speed will slow down accordingly, and the sediment brought by the water body will Most of it enters the water pump and pumps it into the water delivery pipeline, and then deposits in the water delivery pipeline; in addition, the machine sediment for the water pump will also accelerate the wear of the pump impeller
[0005] 3. It needs to be cleaned once a year to clean up the silt in the inlet pool. The pump needs to stop running and the water supply should be interrupted to clean up the sediment. The annual average cost of cleaning up the sediment is more than 200,000 yuan, which leads to high operating costs of the pumping station.
[0006] 4. The silt deposited in the water inlet pool contains algae organic matter. Fermentation begins in May every year, and bubbles can be seen directly on the water surface. It is the most serious in August and September, polluting the water quality of the pumping station
According to the current design codes, there are no specific design codes and standards for the cleaning of sediment in the water pumping station inlet tank, and there are no provisions in the relevant architectural design codes for the water pumping station inlet tank to clean up the sediment

Abstract

The invention discloses a method for cleaning the sediment in the water inlet pool at the front of the water delivery pump station. S1, the water inlet of the water inlet pool is arranged facing the water delivery pump station, and the sedimentation pools are respectively arranged on both sides of the water inlet pool. The wall is separated from the intake tank; the sedimentation tank is composed of a sediment deposition area and a water diversion transition area. The bottom of the sediment deposition area is lower than the bottom of the water diversion transition area and the intake tank; S2, a sand guide groove is set on the bottom of the intake tank to guide the sand. The tank extends from the water inlet to the sediment deposition area; S3, a bypass water diversion pipe is set in the water diversion transition area, and the bypass water diversion pipe is connected with the pumping pipe of the pumping station through an electric valve; S4, when the pumping station is in normal operation, Through the combined action of the diversion holes and the sand guiding grooves on the retaining wall, the water level difference is formed in the inlet pool and the sediment deposition area, and the sediment in the inlet pool is transported to the sediment deposition area; S5, the mud pump is regularly used The vehicle cleans the sediment in the sediment deposition area in a concentrated manner. The invention realizes that the water delivery pump station does not stop when the sediment is cleaned, so as to ensure the normal water supply.

Description

technical field [0001] The invention relates to the field of long-distance water transfer engineering of water conveyance channels, in particular to a method for cleaning the sediment in the water inlet pool at the front of a water conveyance pump station. Background technique [0002] In the long-distance water diversion project of large rivers and canals, it is essential to set up water pumping stations, which provide water supply security for the sustainable development of urban economy and society. The water pumping station usually includes: the front pool, the maintenance gate, the water inlet pool, the pump room and the auxiliary workshop. After the pumping station is put into operation, the staff need to enter the water inlet regularly to clean up the accumulated sediment. When cleaning the sediment, the water pump needs to be stopped to interrupt the water supply. At present, the problems that the staff of the water pumping station encounter in the work process to b...
