Automatic sediment guiding and removing mechanism for water conservancy facility in municipal work

Abstract

The invention discloses an automatic sediment guiding and removing mechanism for a water conservancy facility in a municipal work, and belongs to the technical field of the water conservancy facilities. According to the technical points, the automatic sediment guiding and removing mechanism comprises a concrete sediment guiding and removing body installed at a water inlet of the water conservancyfacility; the upper surface of the concrete sediment guiding and removing body is provided with a first buffer sediment unit and a second buffer sediment unit in a water flow direction in sequence, and the downstream face of the first buffer sediment unit is provided with a sediment guiding mechanism; the upstream face of the second buffer sediment unit is provided with a sediment collecting and removing unit in the width direction; the invention aims to provide the automatic sediment guiding and removing mechanism for the water conservancy facility in the municipal work, with the advantages of compact structure and good sediment removing effect; and the automatic sediment guiding and removing mechanism is used for guiding and removing sediment from the water conservancy facility.

Description

technical field [0001] The invention relates to an auxiliary structure for water conservancy facilities in municipal engineering, and more specifically, to an automatic sediment guide structure for water conservancy facilities in municipal engineering. 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 Chin...

AI Technical Summary

Problems solved by technology

In China, common sand washing and anti-silting measures include setting sand washing flood discharge holes, sand retaining dams, sand guide dikes, sand retaining and discharging facilities upstream of reservoirs, and water and soil conservation measures, but these measures have not effectively solved the sediment problem of power stations , and some measures have a large amount of engineering, high cost, and poor sand removal effect
