Abstract

The invention relates to the technical field of water conservancy facilities, and discloses a sediment guide and removal structure for a water conservancy facility. The sediment guide and removal structure comprises a first upper slope surface, a first lower slope surface, a flow guide plane, a second upper slope surface, a second lower slope surface and a riverbed, wherein the first upper slope surface, the first lower slope surface, the flow guide plane, the second upper slope surface and the second lower slope surface are fixedly arranged on the riverbed, a sand pumping groove is formed in the flow guide plane, a filter cage is fixedly connected to the groove bottom of the sand pumping groove, a silt pump is fixedly connected to the inner cage bottom of the filter cage, the output end of the silt pump is connected with a conveying pipe, the other end of the conveying pipe sequentially penetrates through the filter cage, the groove bottom of the sand pumping groove and the riverbed, and guide blocks are fixedly connected between the flow guide plane and the first lower slope surface and between the flow guide plane and the second upper slope surface. According to the sediment guide and removal structure, the cleaning interval time can be manually controlled, the cleaning speed is high, the work amount is small, the manufacturing cost is low, the sediment discharging effect is good, and meanwhile the sediment pump is protected.

Description

technical field [0001] The invention relates to the technical field of water conservancy facilities, in particular to a sediment guide structure for water conservancy facilities. Background technique [0002] Sediment deposition is a common problem in water conservancy facilities. Due to sediment deposition, the effective storage capacity of the reservoir is reduced year by year, and the regulation performance of the power station is reduced, which affects the use and safety of the upstream engineering of the dam. Big hidden danger. There are a large number of power stations in China that have not solved the problem of flushing and sand discharge. The siltation of the reservoir affects the operation of the power station, and even affects the safety and design service life of the power station. Therefore, the sediment problem is a key issue to be considered in the design of each power station. In China, common sand washing and anti-silting measures include setting sand wash...
