Description

Technical Field

[0001] The utility model relates to the technical field of sewage cleaning in hydropower projects, and particularly relates to a sewage cleaning machine for hydropower projects with an automatic sewage discharge function. Background Technique

[0002] Sewage cleaning in hydropower projects refers to the work of cleaning and removing dirt in water conservancy projects such as hydropower stations, reservoirs, and pump stations. During the process of hydropower generation, a large amount of impurities and sediments are carried in the water. These impurities and sediments will adhere to hydropower equipment, pipelines, and the bottom of the reservoir, affecting the normal operation of hydropower equipment, reducing the hydropower generation efficiency, and even damaging the equipment.

[0003] To maintain the normal operation of hydropower projects, sewage cleaning devices are used to clean the impurities and sediments in the water. According to different sewage cleaning requirements, the sewage cleaning devices will use scraping, sucking and other methods for sewage cleaning.

[0004] During the actual sewage cleaning process of the sewage cleaning device, it is found that the dirty sewage extracted by the sewage cleaning device will be mixed with a large amount of water. The dirty sewage mixed with water will increase the collection volume of the dirty sewage.
