Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and specifically relates to a trash rack device for water conservancy projects. Background Technique

[0002] A trash rack is installed at the inlet of the water intake channel of a hydropower station and the inlet and tail water outlets of a pumped-storage power station, which is a facility used to block sunken wood, branches, weeds and other solid sundries carried by the water flow, so that sundries are not easily introduced into the water channel, to ensure that gates, valves, water turbines, pump turbines, etc. are not damaged and to ensure the normal operation of the equipment. The sundries on the trash rack need to be cleaned in time to reduce water energy loss and prevent the trash rack from being crushed by sundries.

[0003] The existing trash rack can only play a simple role in blocking sundries. When the trash rack blocks sundries at the inlet and outlet for a long time, a large amount of sundries will accumulate and block, affecting the water flow. Therefore, further improvements need to be made on this basis. Content of the Utility Model
