Anti-icing structure of sluicing slope for water conservancy facilities

Abstract

The invention discloses an anti-icing structure of a sluicing slope for water conservancy facilities, and belongs to the technical field of water conservancy facilities. According to the technical keypoints, the anti-icing structure comprises a water storage wall, a sluicing gate arranged on the water storage wall and the sluicing slope arranged on one side of the water outlet end of the sluicinggate; a sluicing table is arranged between the sluicing slope and the sluicing gate, and a closure water tank is formed in the sluicing table; an air jetting tank is arranged in the closure water tank, and the two ends of the air jetting tank are connected with air delivering pipes correspondingly; a plurality of vent holes are distributed in the side wall of the air jetting tank, and the vent holes face toward the bottom of the closure water tank and the water outlet side of the sluicing gate; and a cantilever is arranged on the water storage wall, supporting plates are hinged to the two ends of the air jetting tank, and the free ends of the supporting plates are hinged to the cantilever. The anti-icing structure of the sluicing slope for the water conservancy facilities is compact in structure, low in using energy consumption and good in effect and is used for preventing the water conservancy facilities from icing.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for water conservancy facilities, and more specifically relates to an anti-icing structure for a discharge slope for water conservancy facilities. Background technique [0002] The steep discharge slope is an important hydraulic facility of a diversion-type hydropower station. It protects the diversion channel during the power generation process and undertakes tasks such as drainage, sand removal, and ice removal of the hydropower station. In the northern region, after entering the severe winter, the gates of the forebays of diversion-type small and medium-sized hydropower stations inevitably have water leakage, and the steep discharge slopes are severely frozen after flowing through the steep discharge slopes. The ice-clearing work that requires high labor intensity is time-consuming and labor-intensive, and also endangers the safety of the staff. [0003] At present, there has been ...

Ice clearing work that requires high labor intensity is time-consuming and labor-intensive, and endangers the safety of staff

[0003] At present, there have been anti-icing structures installed with heating pipes on the discharge slope, which can prevent the problem of freezing, but due to long-term heating, it consumes more energy and affects the normal use of the steep discharge slope
