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

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] to combine Figure 1 to Figure 4 , the present invention includes an L-shaped support plate 1, a fish bucket 2, a wide synchronous belt 3, a third transmission shaft 4, a narrow synchronous belt mechanism 5, a power support plate 6, a fish unloading slide 7, a motor 8, an impact plate 9, a third Bearing block 10, second bearing block 11, second transmission shaft 12, first bearing block 13, first transmission shaft 14, third synchronous wheel 15, second synchronous wheel 16, first synchronous wheel 17.

[0015] According to dams of different heights, the present invention designs L-shaped support plates 1 of corresponding heights, and the front of the L-shaped support plate 1 protrudes as a concentrated slow water flow area for attracting migratory fish. Two L-shaped support plates 1 have holes in contact with the water surfac...

Abstract

The invention provides a hydro-electric hybrid driving flipping fish lifting device, which includes two L-shaped support plates arranged downstream of the dam, three transmission shafts arranged between the two L-shaped support plates, and three transmission shafts set on the three transmission shafts. a synchronous wheel, a wide synchronous belt arranged on the three synchronous wheels, a power support plate installed on the L-shaped support plate and a motor installed on the power support plate, and the three transmission shafts are respectively arranged on the L-shaped support plate The first transmission shaft in the horizontal section, the third rotating shaft arranged on the upper part of the vertical section of the L-shaped support plate, and the second transmission shaft arranged directly below the third transmission shaft, and wedge-shaped buckets are uniformly arranged on the wide synchronous belt , A narrow synchronous belt mechanism is arranged between the output shaft of the motor and the third transmission shaft, and a fish unloading slide is arranged upstream of the dam. The invention has the advantages of simple structure, small scale, flexible layout, low operating energy consumption, high migration success rate and good fish passing effect.

Description

technical field [0001] The invention relates to a fish passing device for a dam, in particular to a hydroelectric hybrid driving flipping fish lifting device. Background technique [0002] At present, the management and development of my country's water resources have entered a new stage, and more and more dams and other flow-blocking structures have been built on my country's major rivers. After building dams and gates on the river, the continuity of the original river has been blocked, the inherent natural characteristics of the river have been changed, and the water environment and water ecological environment conditions upstream and downstream of the gate and dam have been relatively greatly affected. Generally speaking, after the construction of diversion gates and dams, the environmental factors (such as water level, flow, water temperature, etc.) Extinction of fish populations. Therefore, as people's awareness of environmental protection increases today, reasonable ...
