Problems solved by technology

After the sand-carrying water flow enters the end of the reservoir, the water depth and width of the water surface increase rapidly, the flow velocity slows down, and the sediment diffuses and settles at the bottom of the reservoir with the water flow. The amount of sediment passing through the turbine gradually increases, causing damage and even blockage in severe cases

Abstract

The invention discloses a disturbance bank tail water flow device. The water flow device comprises a control module installed inside a base, one end of the control module is connected to an external temperature sensor fixed on the base, the other end of the control module is connected to a constant-temperature box; a semiconductor refrigeration piece and an internal temperature sensor are fixed onthe inner wall of the constant-temperature box; a stirrer is fixed on the upper part of the tail part of the base, and the stirrer is connected to the internal control module of the base through a transmission mechanism; and the head of the base is of a fish mouth shape so as to reduce the water flow resistance. The water flow device has the advantages that structure design is reasonable, operation is simple, accurate and fast control decisions can be made according to the detected internal and external temperatures, and the problem of sediment silting is effectively solved.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a device for disturbing the tail water flow of a reservoir. Background technique [0002] Reservoir delta refers to the fan-shaped accumulation body formed by the deposition of sediment carried by the inflow of water in the reservoir tail. After the sand-carrying water flow enters the end of the reservoir, the water depth and width of the water surface increase rapidly, the flow velocity slows down, and the sediment diffuses and settles at the bottom of the reservoir with the water flow. The amount of sediment passing through the turbine gradually increases, causing damage and, in severe cases, even blockage. Weeds and reeds will grow on the surface of the delta out of the water, which will stagnate when a flood occurs and hinder flood control, thus increasing the backwater level of the upstream river section. The main factors affecting the development of the reserv...
