Fish collection-release hopper and base thereof

Abstract

The invention discloses a fish collection-release hopper and a base thereof. The fish collection-release hopper is mainly composed of a fish collection chamber, a fish release chamber and a valve mechanism, wherein the fish collection chamber is located above the fish release chamber, a gate is arranged between the fish collection chamber and the fish release chamber, the valve mechanism is mainly composed of a valve rod vertically penetrating through the gate and a valve arranged at the top of the valve rod, fish release ports used for releasing fishes in the fish collection chamber into a river are symmetrically formed in the sidewall of the fish release chamber, and a valve rod guide support part used for guiding the valve rod to vertically move up and down is arranged on the inner wall of the fish release chamber; and the base is mainly composed of a base body, a through hole formed in the top of the base body and convenient for the valve rod to vertically penetrate through, a horizontal floating rod located in the base body and capable of pushing the valve rod, two vertical floating rods symmetrically arranged at the two sides of the horizontal floating rod and penetrating out of the top of the base body, and two floating balls arranged at the tops of the vertical floating rods. The fish collection-release hopper is simple in structure and energy-saving; and the fishes in a fish collection hopper fall into a fish release hopper and flow into the river from the fish release ports after the valve is opened.

Description

technical field [0001] The invention relates to the technical field of fish passing facilities, in particular to a fish collecting bucket and its base. Background technique [0002] With the acceleration of China's water resources development, the number and scale of dams in major river basins are increasing, and the construction of water conservancy projects has blocked the originally connected rivers, which has had a great impact on fish and their river ecosystems . Fish passing facilities have been paid more and more attention as an important measure to alleviate the blocking problem of water conservancy projects. However, most of the existing fish passing facilities usually require mechanical power systems, which consume a lot of energy and have complex structures. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, provide a simple-structured, energy-saving fish buc...
