Hydropower station floating trash discharge device

Abstract

The invention discloses a floating waste-stopping device of a hydropower station, which comprises two slide rails, the two slide rails are respectively fixed on the walls on both sides of the water inlet of the dam, and a trolley is slidably connected to the two slide rails, and the trolley is connected to the two slide rails. The two ends of the truss structure are hinged, and the truss structure is formed by hinged ends of the float units. The bottom side of the truss structure is fixed with a trash net, and the bottom side of the trash net is fixed with heavy objects; the trash control device of the present invention has a simple structure and is convenient for installation and maintenance. , It can flexibly float up and down and adjust the structure with the change of water level, the stability of the trash blocking device is good, and the trash blocking efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of floating slag blocking, and relates to a floating type silt blocking and discharging device for a hydropower station. Background technique [0002] In water conservancy, hydropower and water intake projects, it is necessary to use a slag and pollution-retaining device to filter out the floating or suspended matter in the water body. At present, the domestic slag-retaining and sewage-retaining device is mainly a movable slag-retaining and pollution-retaining device supported at both ends. There are two types of trash drains and floating trash drains. The fixed trash drains anchor the anchor heads at both ends of the trash drains in the gate pier or buttress. The structure is simple but cannot be adaptively floated with the change of the inlet water level. , only suitable for hydropower stations where the water level varies within a few meters; the floating sewage interception device connects one or both en...

Problems solved by technology

[0002] In water conservancy, hydropower and water intake projects, it is necessary to use slag and trash blocking devices to filter out floating or suspended solids in the water body. There are two types of trash rack and floating trash rack. The fixed trash rack anchors the anchor heads at both ends of the trash rack in the gate pier or pier. Its structure is simple but it cannot be adaptively floated with the water level of the inlet. , only suitable for hydropower stations with water level variation within a few meters; the floating trash rack connects one or both ends of the trash rack device to a movable trolley that can be lifted, and the vertical mobile trolley installed in the concave track of the fixed pier , to realize the up and down floating of the trash rack. The main body of the floating trash rack can float up and down with the change of the reservoir water level when the reservoir water level varies greatly. However, the vertical lifting pier head structure of the existing floating trash rack is complex , large amount of construction, relatively high investment cost
