Problems solved by technology

[0003] Conventional hydroelectric power generation needs to build dams, but building dams means that the fish schools on both sides cannot communicate, and if things go on like this, the genes of the upstream and downstream fish will be degraded. The present invention describes a fish communication device on both sides of the stream dams. , can solve the above problems

Abstract

The invention discloses a device for exchanging fish shoals on two sides of a stream retaining dam. The device comprises a shell, wherein a release space is arranged on the upper right side of the shell and communicates with the outside through a release pipeline. According to the retaining dam which is constructed by intercepting stream, one section of stream is intercepted, a certain height canbe formed at upstream and downstream parts of the dam, power can be generated through the height difference, but due to the facts that upstream and downstream parts are separated and fishes in the stream need to migrate by a certain distance in the growth process, fish shoal separation can be caused by damming, exchange is reduced, gene degradation is caused, and downstream fish shoals cannot migrate; and the device can automatically attract downstream fishes into the device in a certain period, the fishes are automatically conveyed to the upstream part for releasing through a conveying device, the downstream fishes are conveyed to the upstream part, upstream and downstream fish shoals can exchange with each other, the fishes can migrate to the upstream part, and therefore, damage of damming to stream fish resources is effectively reduced.

Description

technical field [0001] The invention relates to the field of hydroelectric power generation, in particular to a fish communication device on both sides of a stream dam. Background technique [0002] Hydropower is a way of generating electricity, and the water energy used is mainly the potential energy stored in the water body. It uses buildings to concentrate the drop of natural water flow to form a water head, and collects and regulates the flow of natural water flow with a reservoir; the basic equipment is a hydroelectric generator set. When the water flows through the water turbine, the water turbine is driven by the water flow to rotate, and the water turbine drives the generator to generate electricity. The mechanical energy is converted into electrical energy, and then the electricity is sent to the user through power transformation and power transmission and distribution equipment. Water energy is a renewable energy source in nature, and it is regenerated repeatedly ...
