TECHNICAL FIELD
[0001] The utility model relates to water conservancy and hydropower technical field, concretely relates to a water collecting well with both functions of collecting and cleaning sewage. BACKGROUND
[0002] In the underground powerhouse and dam structure of hydropower stations and pumped storage power stations, a water collecting well is usually arranged for collecting seepage water from the drainage gallery of each floor of the powerhouse, the drainage gallery of the dam and the rock wall. The seepage water often carries impurities such as silt, which is deposited at the bottom of the water collecting well for a long time. If it is not cleaned in time, it will affect the normal operation of the seepage drainage pump, possibly cause equipment damage, and further affect the seepage water discharge, and even cause safety accidents such as water flooding of the pump house. Since such water collecting wells are usually located deep in the powerhouse or dam, conventional inspection cannot cover them. In addition, modern power stations are gradually transforming into unattended or less attended mode. The cleaning of silt in the water collecting well still needs to rely on manual regular downhole operation and starting of a submersible sewage pump for cleaning. However, the water collecting well is usually large in area and deep, and manual collection of silt not only consumes time and effort, but also has certain safety risks. SUMMARY
