Automatic oblique suspension water-blocking overflow impurity removal device

Abstract

The invention discloses an automatic oblique suspension water-blocking overflow impurity removal device which comprises a water channel (8), a trash rack (3) and an overflow / flood discharge opening, wherein a primary overflow inclined suspension water-blocking beam (1), a secondary overflow inclined suspension water-blocking beam (2) and an impurity overflow groove (5) are arranged in the water channel; the primary and secondary overflow inclined suspension water-blocking beams are obliquely fixed in the water channel, and the inclined end parts of the primary and secondary overflow inclined suspension water-blocking beams are fixed at the overflow / flood discharge opening to divide the overflow / flood discharge opening into a primary overflow / flood discharge opening (6) and a secondary overflow / flood discharge opening (7); the trash rack (3) is fixed below the primary overflow inclined suspension water-blocking beam through the impurity overflow groove (5). According to the device, filtered floating impurities are driven by overflow water to be discharged from the overflow / flood discharge opening under the water-blocking function of the inclined suspension beams on the premise of ensuring sufficient dynamic filtering water, so that the aims of automatically discharging the floating impurities, lowering the manufacturing and maintenance cost of the device, facilitating the mounting and use of the device and running the device with low cost are fulfilled.

Description

technical field [0001] The invention belongs to the technical field of a sundry discharge device for a waterway of a hydropower station, and mainly relates to an obliquely suspended water and overflow automatic waste discharge device. It is widely used in rivers, canals, and waterways with a certain drop, especially for the removal of dirt from water supply channels for hydropower stations. Background technique [0002] The various hydropower stations known to utilize water energy resources to build are equipped with waste discharge devices, such as: grid rotary cleaning machines, booster bucket cleaning machines, etc., in order to block and filter impurities in water. material to ensure the normal operation of the turbine. However, these waste discharge devices are all mechanical equipment, which remove debris through mechanical power circulation, and consume electric energy during operation, which not only increases operating costs, but also increases manufacturing costs,...
