Abstract
Description
Technical Field

[0002] The planning area of the East Line Project is located in the middle and lower reaches of the Yangtze River in my country. Due to the flat terrain and small river gradient in the area, vertical axial flow pump stations with large flow and low head are widely used, among which the water inlet channel mostly adopts the elbow-shaped water inlet channel type with better hydraulic performance. However, due to the flat terrain in the area, the low river flow rate and the high sand content of the river near the Yangtze River estuary, during the operation of the pump station, silt is easy to accumulate at the elbow where the cross-section of the water inlet channel changes most dramatically. Over time, the silt at the elbow will form a block, resulting in a decrease in the water flow section area of the channel and an increase in the water flow rate, making the water flow velocity and inflow angle of the pump inlet flow poor, greatly affecting the economic and stability of the pump station operation.
[0003] The existing silt removal device has a fixed angle, resulting in a relatively low cleaning range and being unable to effectively remove the accumulated garbage. Utility Model Content
