Problems solved by technology
[0005] In order to overcome the existing shortcomings of the inability to quickly filter the water flow when filtering the overflow water flow, the filtered impurities need to be manually scraped from the filter net, and it is not convenient to collect the filtered impurities in a centralized manner. The technical problem of the invention is: to provide a filter rack for overflow dam water diversion that can quickly filter the overflow water flow and facilitate the centralized collection of filtered impurities

The invention relates to a trash holding frame, in particular to a filtering trash holding frame for water diversion of an overflow type dam body. The filtering trash holding frame comprises a dam body, a trash holding frame, a trash holding assembly, a water power driving assembly, a scraping assembly and the like, wherein the trash holding frame is placed on a dam body, the trash holding assembly is arranged on the trash holding frame, the water power driving assembly is arranged on the dam body, and the scraping assembly is arranged on the water power driving assembly. Through cooperation of a collecting plate, a frame plate, a filter screen and devices on the filter screen of the trash holding assembly, impurities in water flow are filtered out, and the effect that the water flow flows into a river channel more cleanly is achieved.
Description
technical field [0001] The invention relates to a trash rack, in particular to a filter trash rack for water diversion of an overflow dam body. Background technique [0002] The water diversion system is a general term for hydraulic structures such as water intake and water delivery from reservoirs or rivers to water turbines. According to the type of hydropower station and the terrain and geological conditions, the water diversion system includes buildings such as the water inlet of the hydropower station, the diversion channel, the pressure forebay, the surge chamber and the pressure pipeline. The dam body is an important barrier of the water diversion system, in which the water flowing from the dam body is called the overflow flow, which is the main source of power for the hydrodynamic equipment. [0003] In order to ensure the normal operation of hydrodynamic equipment, it is necessary to ensure the cleanliness of the water flow. If the water flow is not clean enough, i...
