[0002] While modern hydropower projects strive to achieve economic benefits, they often also need to consider ecological benefits. Building new fish-passing facilities is an important measure to protect the ecological environment. A fish collection and transportation system is a fish-passing facility specifically designed to assist fish in safely passing through hydraulic structures such as hydropower stations and dams. This system is usually installed near the dam, creating a "special elevator" for fish. The collected fish are transported to the upstream of the dam for release through the system. The purpose is to increase the connectivity of upstream and downstream river ecosystems, especially for those fish that need to migrate upstream and downstream for reproduction or foraging. It is mainly used in high dam areas. Generally, a complete fish collection and transportation system includes steps such as luring fish, gathering fish, running fish, sorting fish, transporting fish, and releasing fish. Among them, the fish running device is mainly a smooth channel with a certain inclination angle, which uses water flow to guide fish to glide to a designated location, minimizing harm to the fish.

[0034] Mesh cover 301 , reinforced cover 302 , handle 303 . DETAILED DESCRIPTION

[0035] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] See also Figure 1-12A fish-stirring device suitable for a fish collection and transportation system includes a bracket 6 for supporting the entire device. The top of the bracket 6 supports a fish trough 1. The top of the fish trough 1 is hinged with an anti-escape cover 3 that can be flipped open. The inner top of the fish trough 1 is fixedly mounted with a water pipe 2 via a top crossbeam 103 and a U-shaped clamp 4. The water pipe 2 is mounted with multiple nozzles 5, and the nozzles 5 are arranged inside the fish trough 1. By adopting the above-mentioned fish-stirring device, damage caused by stress reactions of fish during the fish-stirring process is reduced. The provision of the spray device ensures continuous water replenishment of the fish trough 1, and the anti-escape cover 3 can prevent fish from jumping out of the fish trough 1. The entire fish-stirring device is highly practical, has a good fish-stirring effect, and has controllable manufacturing costs. It provides a solution for fish collection and transportation systems to achieve long-distance fish-stirring with complex trajectories. In specific use, during the fish-stirring process, water is supplied to the water pipe 2, and then to the interior of the fish trough 1, thereby ensuring normal fish-stirring.

[0038] Furthermore, the water pipe 2 and the nozzle 5 form a spraying device. When fish need to be reeled in, the water replenishing system is started and water is continuously replenished to the fish tank 1 through the nozzle 5.

[0039] Furthermore, the bracket 6 is made of welded steel and is supported on three sides. The bracket 6 is fixed to the fish trough 1 by bolts. The height difference of the bracket 6 supporting the fish trough 1 is used to adjust the slope of the fish trough 1, thereby ensuring the normal operation of the subsequent fish trough.

[0040] Furthermore, the fish slide 1 includes a U-shaped trough 102 having a smooth inner wall. A connecting flange 101 is provided at the end of the U-shaped trough 102. Multiple sets of top crossbeams 103 are provided at the top of the U-shaped trough 102. The top crossbeams 103 are provided with through holes 104 for mounting the U-shaped clips 4. By using the U-shaped trough 102 and ensuring its smooth inner wall, damage to the fish during the slide is reduced.

[0041] Furthermore, the fish slide 1 further comprises a planar arc-shaped elbow fish slide 7, and adjacent fish slides 1 are connected by the elbow fish slide 7 to change the direction of the entire fish slide. The elbow angle can be set according to actual conditions.

[0042] Furthermore, the fish slide 1 includes an S-shaped fish slide 8. Adjacent fish slides 1 are connected by the S-shaped fish slide 8 to change the overall height or direction of the fish slide. This can accommodate complex directional changes. The elbow angle can be set according to actual needs.

[0043] Furthermore, the corners of the elbow fish trough 7 and the S-shaped fish trough 8 are rounded to achieve a smooth transition, thereby reducing damage to fish.

[0044] Furthermore, the anti-escape cover 3 includes a mesh cover 301, on which are disposed a plurality of reinforced cover bodies 302, and a handle 303 is disposed on the opening side of the anti-escape cover 3. The anti-escape cover 3 not only facilitates the inspection of the fish in the fish tank 1, but also reduces the weight of the anti-escape cover 3. The anti-escape cover 3 is welded with two handles for easy opening.

[0045] Furthermore, the connecting flanges 101 of adjacent fish slides 1 are fastened by bolts 9, and rubber pads are installed on the connecting end faces of the connecting flanges 101. The rubber pads ensure the sealing of the connection and the smoothness of the transition of the connection of the fish slide 1.

[0046] Furthermore, a water leakage mesh 106 is provided on the U-shaped trough body 102 of the last section of the fish slide trough 1, and a drainage box 105 is provided just below the water leakage mesh 106. The provision of the water leakage mesh 106 can reduce the migration of fish in the trough, thereby improving the fish slide effect.

[0047] In this embodiment, the aperture of the water leakage mesh 106 is set to 5 mm, the water leakage mesh 106 is arranged in 49 columns horizontally and 8 rows vertically, and the drainage box is welded to the fish trough 1.

[0048] Example 2:

[0049] The present invention also provides an embodiment, such as Figure 13 The diagram shows the structure of a connected fish-playing device. In this embodiment, two fish-playing devices are connected together. Multiple fish-playing devices can be connected in series, each of which is fixedly connected to the fish-playing trough 1 by bolts 9. The connection of the fish-playing devices increases the distance of the fish.

[0050] Example 3:

[0051] The present invention also provides an embodiment, such as Figure 14 The figure shows a structural diagram of the connection of a fish-sliding device with an elbow fish-sliding trough 7. By connecting two adjacent fish-sliding devices through the elbow fish-sliding trough 7, the direction of the fish-sliding trajectory can be changed. In this embodiment, the angle of the elbow fish-sliding trough 7 is 120 degrees.

[0052] Example 4:

[0053] The present invention also provides an embodiment, such as Figure 15 The figure shows a schematic diagram of a fish sling with an elbow trough 7 and an S-shaped trough 8. The elbow trough 7 and S-shaped trough 8 connect two adjacent fish slings, adjusting the height difference between the troughs. The combination of the elbow trough 7 and S-shaped trough 8 accommodates complex directional changes. In this embodiment, the elbow angle of the S-shaped trough 8 is 135 degrees.

[0054] By directly connecting the fish-stirring device with the combined connection of the fish-stirring device with an elbow, a long-distance complex fish-stirring trajectory can be achieved.
