Water diversion device with automatic cleaning function for water turbine

Abstract

The invention discloses a water diversion device with an automatic cleaning function for a water turbine. The water diversion device comprises a water diversion device body. The water diversion devicewith the automatic cleaning function for the water turbine is simple in structure; dirt on a filter screen is scraped away through large wiping blocks on strip-shaped scraping plates; when the strip-shaped scraping plates rotate, attraction force between strip-shaped magnets and iron sliding rods is weakened, under the action of third springs, the iron sliding rods move leftwards, the dirt on thefilter screen is wiped away by small wiping blocks, and thus the cleaning efficiency is improved; when the strip-shaped magnets move rightwards, two triangular blocks move oppositely, rotating rods rotate, and arc-shaped rods are clamped by limiting grooves so that the small wiping blocks can wipe the filter screen more stably; meanwhile, first electric conduction pieces make contact with secondelectric conduction pieces, second motors drive rotating discs to rotate, winding discs rotate forwards and backwards through connecting rods, the small wiping blocks move up and down for wiping underthe action of pull ropes and fourth springs, and thus the cleaning efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of a water diversion device for a water turbine, in particular to a water diversion device for a water turbine with an automatic cleaning function. Background technique [0002] In the hydropower generation system, the water diversion chamber of the turbine is the first part where the water flow enters the turbine, and it is mainly responsible for introducing upstream water into the downstream to impact the turbine for power generation. Generally, a pre-filter is placed on the water inlet pipe of the water diversion chamber to filter to block impurities such as sediment in the water flow. As time goes by, the filter screen on the siphon pre-filter will accumulate a large amount of impurities and needs to be cleaned. The prior art The self-cleaning efficiency of the intermediate filter is low, and the cleaning is not thorough, which affects the subsequent use of the siphon pre-filter. Therefore, a water diver...

Generally, a pre-filter is placed on the water inlet pipe of the water diversion chamber to filter to block impurities such as sediment in the water flow. As time goes by, the filter screen on the siphon pre-filter will accumulate a large amount of impurities and needs to be cleaned. The prior art The self-cleaning efficiency of the intermediate filter is low, and the cleaning is not thorough, which affects the subsequent use of the siphon pre-filter. Therefore, a water diversion device for a water turbine with an automatic cleaning function is proposed
