Stopping device for water getting in hydropower station

Abstract

The invention discloses a stopping device for water getting in a hydropower station. The stopping device comprises a trash rack, a stopping plate, a geogrid, a steel rope, a cylinder and two fixed pulleys, wherein the stopping plate comprises an outer baffle and an inner baffle, the outer baffle is fixed to the lower portion of the trash rack, and the inner baffle is movably mounted in the outer baffle. The two fixed pulleys are symmetrically fixed above the trash rack, and the two ends of the steel rope wind across the two fixed pulleys correspondingly and then are symmetrically fixed to the two sides of the upper portion of the inner baffle; a piston rod of the cylinder is fixedly connected to the middle of the steel rope, and the cylinder controls the inner baffle to go up and down through the steel rope; the geogrid is fixed to the upper portion of the trash rack and located between the inner baffle and the trash rack. According to the stopping device, the height of the stopping plate can be adjusted in real time according to the water level at a water getting opening, and therefore the best silt stopping effect is achieved.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering, and in particular relates to an intercepting device for water intake of a hydropower station, which is mainly used for intercepting suspended sediment in water during water intake. Background technique [0002] Generally, in water conservancy and hydropower projects with sediment problems, the sediment accumulation at the water intake of the power station is not conducive to the normal diversion of water to generate electricity at the water intake, and even endangers the safety of water intake buildings. In water conservancy and hydropower projects, the water inlet of the power station generally adopts sand barriers or sand discharge tunnels to deal with sediment problems. Due to factors such as the flow state and scope of the water flow, there are uncertainties in the deposition of silt, and it is often difficult to deal with it. Especially during the construction peri...

Problems solved by technology

However, in actual use, since the height of the steel plate on the trash rack is fixed, and the water level at the water intake is constantly changing, people cannot adjust the height of the steel plate in real time according to the water level, resulting in a lack of awareness of suspicious sediment. Poor blocking effect
