Embodiment 1

[0033] see Figure 1 to Figure 5 , the present embodiment provides a new fully automatic roller-type fish passing device, including a waterwheel power system, a roller-type fish passing system and a dam body 6 .

[0034] The waterwheel power system is arranged on the downstream side of the dam body 6 . The waterwheel power system includes a driving wheel 2 and a transmission rod 3 arranged coaxially, and a plurality of water buckets 1 . The two ends of the transmission rod 3 are marked as end A and end B respectively. The end A of the transmission rod 3 is fixed at the center of the driving wheel 2 . A plurality of water buckets 1 are evenly fixed on the peripheral wall surface of the driving wheel 2 . The opening direction of the water bucket 1 is opposite to the rotation direction of the water wheel.

[0035] The roller fish passing system includes a plurality of migrators 4 and driven wheels 5 arranged on the downstream side of the dam body 6 , and an auxiliary fish pas...

Embodiment 2

[0038] The main structure of this embodiment is the same as that of Embodiment 1, wherein, the driving wheel 2, the migrator 4, the driven wheel 5 and the auxiliary fish channel 7 are all made of plexiglass.

Embodiment 3

[0040] The main structure of this embodiment is the same as that of Embodiment 1, wherein the migrator 4 includes a straight rectangular plate 402 , an arc plate 403 and a straight fan ring plate 404 . The flat rectangular plate 402 , the arc-shaped plate 403 and the straight fan ring plate 404 form a semi-circle. The migrator 4 and the driven wheel 5 enclose a fan ring cylinder cavity. The sector ring cylinder includes two bottom surfaces and four side surfaces. The straight ring fan plate 404 and the release window 401 correspond to the two bottom surfaces of the ring fan cylinder. The arc plate 403 and the peripheral wall of the driven wheel 5 correspond to the two arc sides of the sector ring cylinder. The straight rectangular plate 402 and the opening of the migrator 4 correspond to the two straight sides of the fan ring cylinder.

[0041] The straight rectangular plate 402 and the circular arc plate 403 are provided with vertical slits and permeable holes to reduce wa...

Abstract

The invention provides a novel full-automatic roller type fish passing device. The fish passing device comprises a waterwheel power system, a roller type fish passing system and a dam body. The waterwheel power system is arranged on the downstream side of the dam body. The waterwheel power system comprises a driving wheel, a transmission rod and a plurality of water containing buckets, wherein the driving wheel and the transmission rod are coaxially arranged. Two ends of the transmission rod are respectively marked as an end A and an end B; the end A of the transmission rod is fixed to the center position of the driving wheel. A plurality of water containing hoppers are evenly fixed to the circumferential wall face of the driving wheel. And the opening direction of the water containing hopper is opposite to the rotating direction of a waterwheel. According to the fish passing device, the gravitational potential energy of water is converted into kinetic energy needed for lifting fishes to the upstream, and the efficient conversion of green energy is reflected. The whole process is automatic, manual and extra energy input is not needed, and the energy is saved.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering ecological environment, in particular to a new type of fully automatic roller-type fish passing device. Background technique [0002] Water retaining structures such as sluices and dams cut off the natural channel, which has a great impact on the migration and reproduction of fish. With the introduction of the concept of green development, many ecological protection measures have been taken in the construction of water conservancy projects to reduce the adverse impact on the ecological environment. With the increasing scale of water conservancy projects in my country and more and more high-head water conservancy facilities, the impact of dams on natural river ecosystems will become more serious. [0003] However, the fish luring effect and fish loading efficiency of the existing fish passing devices are not ideal, and the motor needs to be used as the driving force, and...
