Automatic fishing ladder utilizing river water to generate electricity

Abstract

The invention discloses an automatic fishing ladder utilizing river water to generate electricity. The fish ladder comprises a riverbed, a transmission cavity is formed in the riverbed, the upper side of the transmission cavity is provided with a reverse flow sliding groove with an upward opening in a communicating mode, chain wheel rotating shafts which are symmetrical left and right are rotationally connected between the front wall and the rear wall of the transmission cavity, the chain wheel rotating shaft on the left side is located on the upper side of the chain wheel rotating shaft on the right side, the outer circle faces of the chain wheel rotating shafts are fixedly sleeved with chain wheels, a chain is wound between the left chain wheel and the right chain wheel, and vertically-symmetrical chain fixing blocks are fixedly connected to the end faces of the sides, away from the chain wheel rotating shafts, of the chains correspondingly. By changing the shape of the fish ladder, electric power is provided through hydroelectric power generation equipment, then the fish ladder is driven to flow upwards and be thrown out, and therefore fishes needing to lay eggs and breed can conveniently return to the upstream, the survival rate is increased, meanwhile, assistance is provided for the fishes; and the fish ladder on the upper side can be lifted and the shape of the fish ladder can be changed, and therefore, maintenance personnel can maintain conveniently.

Description

technical field [0001] The invention relates to the technical field of water conservancy power generation equipment, in particular to an automatic fish ladder using river water to generate electricity. Background technique [0002] In our daily life, hydropower is a common means of energy saving. When the upstream water flows to the lower place after opening the sluice, it converts the gravitational potential energy into electrical energy, but after it is put into use, it will cause irreversible damage to the ecological environment. Due to the influence of some fish species, some fish cannot return to the upstream to reproduce, and because of its terrain, it is difficult for maintenance personnel to maintain. Existing fish ladders cannot go up automatically, but can only provide them with a resting space, and cannot assist fish. An automatic fish ladder that utilizes river water to generate electricity described in the present invention can solve the above problems. Conten...

[0002] In our daily life, hydropower is a common means of energy saving. When the upstream water flows to the lower place after opening the gate, it converts the gravitational potential energy into electric energy, but after it is put into use, it will cause irreversible damage to the ecological environment. Some fish cannot return to the upstream to reproduce, and due to its terrain, it is difficult for maintenance personnel to maintain

Existing fish ladders can't go up automatically, they can only provide them with a resting space, and they can't help the fish. An automatic fish ladder that uses river water to generate electricity can solve the above problems.
