Hydroelectric generation device for helping fishes to migrate

Abstract

The invention discloses a hydroelectric generation device for helping fish to migrate. The hydroelectric generation device comprises a wall body, a left-right through turbine cavity is formed in the wall body, a turbine is rotatably arranged on the inner wall of the turbine cavity, and a left-right through drainage cavity is formed in the upper side of the turbine cavity. Hinging cavities which are in bilateral symmetry with respect to the turbine and provided with openings away from one side of the axis of the turbine are formed in the upper side part of the drainage cavity in a communicatingmode, upper transmission cavities with openings away from one side of the axis of the turbine are formed in the upper sides of the hinging cavities, and power bevel gear cavities which are in bilateral symmetry with respect to the axis of the turbine are formed in the lower side of the turbine cavity. Fish at the hydroelectric generation position is fished and conveyed to the other position, thefish is prevented from being extruded by a turbine unit when passing through a hydroelectric power station, meanwhile, normal use of the turbine unit can also be guaranteed, the service life of the turbine is prolonged, the hydroelectric generation device can help the migrating fish to cross over the turbine unit, and therefore, smooth migrating and spawning of the fish can be protected.

Description

technical field [0001] The invention relates to the related field of hydroelectric power generation equipment, in particular to a hydroelectric power generation device for helping fish to migrate. Background technique [0002] Hydroelectric power generation is a science and technology that studies technical and economic issues such as engineering construction and production operation that convert water energy into electrical energy. It is the mechanical energy of the water wheel, and then the mechanical energy is used to drive the generator to obtain electricity; hydropower generally stores the water flow by building a dam, but the existence of the dam will hinder the fish from migrating, which will make the river flow The quantity of fish decreases in a large number, thereby slowly destroying the ecological system of the river, causing a large number of animals and plants with fish as natural enemies to flood in the river, thereby causing pollution of the river and increasi...

[0002] Hydroelectric power generation is a science and technology that studies technical and economic issues such as engineering construction and production operation that convert water energy into electrical energy. It is the mechanical energy of the water wheel, and then the mechanical energy is used to drive the generator to obtain electricity; hydropower generally stores the water flow by building a dam, but the existence of the dam will hinder the fish from migrating, which will make the river flow The quantity of fish decreases in a large number, thereby slowly destroying the ecological system of the river, causing a large number of animals and plants with fish as natural enemies to flood in the river, thereby causing pollution of the river and increasing the economic cost of cleaning the river. The present invention explains A hydroelectric power generation device that helps fish migrate, which can solve the above problems
