Water-electricity hybrid driven overturning fish rising device

Abstract

The invention provides a water-electricity hybrid driven overturning fish rising device. The water-electricity hybrid driven overturning fish rising device comprises two L-shaped supporting plates arranged at the downstream part of a dam, three transmission shafts arranged between the two L-shaped supporting plates, three synchronous wheels arranged on the three transmission shafts in a sleeving manner, a wide synchronous belt arranged on the three synchronous wheels, a power supporting plate arranged on one L-shaped supporting plate, and a motor arranged on the power supporting plate. The three transmission shafts include a first transmission shaft arranged on the horizontal sections of the L-shaped supporting plates, a third transmission shaft arranged at the upper portions of the vertical sections of the L-shaped supporting plates, and a second transmission shaft arranged under the third transmission shaft. Wedge-shaped fish hoppers are evenly arranged on the wide synchronous belt. A narrow synchronous belt mechanism is arranged between an output shaft of the motor and the third transmission shaft. A fish unloading slide is arranged on the upstream part of the dam. The water-electricity hybrid driven overturning fish rising device is simple in structure, small in scale, flexible in arrangement, low in running energy consumption, high in running success rate and good in fish passing effect.

Description

Technical field [0001] The invention relates to a dam fish passing device, in particular to a hydroelectric hybrid driving flipping fish raising device. Background technique [0002] At present, the governance and development of my country's water resources has entered a new stage, and more and more dams and other isolation structures have been built on major rivers in my country. After dams and gates are built on the river, the continuity of the original river is blocked, the inherent natural characteristics of the river are changed, and the water environment and water ecological environment conditions of the upstream and downstream of the gate and dam are relatively large. Generally speaking, after the dam is constructed, the environmental factors of fish habitat (such as water level, flow, water temperature, etc.) will change, which will have an important impact on fish activities and may directly lead to some upstream migration The extinction of fish stocks. Therefore, as p...

Problems solved by technology

However, the limitations of the existing fishways can only reduce the water flow velocity in the fishway, and the flow velocity in the fishway is extremely unstable. At the same time, the water retaining facilities inside the fishway also block the migration route of fish, so it is difficult for fish in practice. Through the fishway, so the fish passing efficiency is low
