Adjustable trash holding device

Abstract

The adjustable trash holding device is characterized in that a trash holding buoyancy tank is arranged at a fishway outlet, embedded tank grooves are formed in the two sides of the fishway outlet, and the trash holding buoyancy tank is located in the tank grooves; a traction device is arranged on the pier top and connected with the trash holding buoyancy tank through a lifting chain. The lifting chain is circuitously placed and fixed at the top of the trash holding buoyancy tank; the trash holding floating box floats up and down in the tank along with the change of the water level in the reservoir; and the traction device is used for pulling the trash holding buoyancy tank to move up and down in the tank groove. The traction device is arranged on the pier top to pull the lifting chain to pull the trash holding buoyancy tank, the lifting chain is circuitously placed and fixed to the top of the trash holding buoyancy tank, and after the chain is lifted, the number of placed balance weights of the trash holding buoyancy tank can be reduced, so that the immersion depth of the trash holding buoyancy tank can be adjusted, and the trash holding buoyancy tank can be lifted to the pier top to be overhauled; the box groove can limit the trash holding floating box, and the problem that a traditional floating type box body is poor in trash holding effect is solved.

Description

technical field [0001] The invention belongs to the technical field of reservoir trash-stopping devices, and in particular relates to an adjustable trash-stopping device. Background technique [0002] Fishway is an important facility connecting fish migration routes. It plays an irreplaceable important role in connecting fish migration routes on low-head water conservancy projects, and is one of the key contents of ecological protection and restoration technology of hydraulic engineering. The water level of some reservoirs fluctuates greatly, such as the power generation of power stations, water intake for irrigation and other functional needs, and the water level of the reservoir needs to be adjusted periodically. As a result, the water level of the reservoir has fluctuated greatly, and the number of floating objects has also increased to a certain extent. The vertical seam of the fishway is generally 30cm wide, and there are often fish driving equipment, etc. If no effect...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an adjustable dirt-stopping device to solve the problem of changing the draft required for normal dirt-stopping due to the attachment or interference of dirt to the floating tank under the action of the actual dirt accumulation in the traditional floating tank Depth and surfacing height, the problem that affects the pollution blocking effect
