DETAILED DESCRIPTION OF SOME EMBODIMENTS

[0028] We shall further describe the present disclosure in detail in combination with the drawings and examples as follows.

[0029] As shown in FIGS. 1-6, a water-replenishing fishway with an adaptively-adjusted floating dock, comprising: a fishway body 1, wherein the bottom of the fishway body 1 is rotationally connected with a floating dock structure 5, an auxiliary swimming structure 2 is arranged inside the fishway body 1, and an adjusting structure 6 used to adjust the auxiliary swimming board 21 of the auxiliary swimming structure 2 is arranged on the floating dock structure 5.

[0030] Preferably, the auxiliary swimming structure 2 includes a plurality of auxiliary swimming boards 21, each of which is rotationally connected with one end of an interacting column 22, the other end of the interacting column 22 is rotationally connected with one end of a sliding block 23, and the other end of the sliding block 23 is slidingly connected to the fishway body 1.

[0031] Preferably, the fishway body 1 is excavated with a sliding groove 25 fitting with the sliding block 23, a first spring 24 is arranged between the sides of the sliding groove 25 and the sliding block 23, and the bottom of the sliding block 23 is articulated with a roller 27, which is in contact with the surface of the moving plate 61 of the adjusting structure 6.

[0032] In the technical scheme, the fishway body 1 is installed between the upstream and downstream, so that the water flows through the inner wall of the fishway body 1, thus the water overflows the auxiliary swimming board 21. The downstream fish swim into the inside of the fishway body 1 through the guiding board 4, and arrive at the top of the fishway body 1 through a plurality of auxiliary swimming boards 21 successively step by step, so that the fish swimming upstream through the auxiliary swimming board 21 can stay between the auxiliary swimming board 21 and the inner wall of the fishway body 1 to rest when they are exhausted.

[0033] Furthermore, the auxiliary swimming board 21 set at an inclined upward angle can prevent the fish from washing downstream by a water flow during rest, and the upstream fish can wash directly downstream with a water flow through the fishway body 1. As the auxiliary swimming board 21 rotates, the interacting column 22 moves, pushing the sliding block 23 to slide back and forth on the inner wall of the fishway body 1, so that the first spring 24 compresses and elongates, always supporting the auxiliary swimming board 21 and effectively assisting the fish's migration.

[0034] Preferably, an air delivering device 3 is further arranged on the fishway body 1, the air delivering device 3 includes a housing 31, inside which is arranged an air pump 35, the output end of which is connected to one end of an air delivering pipe 32, and the other end of the air delivering pipe 32 is connected to a plurality of air inlet pipes 33, each of which is provided with an unidirectional air outlet valve 34.

[0035] Preferably, a top block 36 is fixed on one side of the unidirectional air outlet valve 34, the top block 36 props against on one side of an adjusting plate 37, and the other side of the adjusting plate 37 is connected with the auxiliary swimming board 21 by means of a second spring 38.

[0036] Preferably, a guiding board 4 is further arranged on the downstream end of the fishway body 1, and the guiding board 4 is a triangular column structure.

[0037] Preferably, the floating dock structure 5 includes a fixing base 51, the surface of which is provided with a mounting hole 53, the top of the fixing base 51 is fixedly connected with the bottom of a fixing frame 52, one side of the fixing frame 52 is fixedly connected with a waterproof cover 56, a motor 55 is fixed inside the waterproof cover 56, the output end of the motor 55 is fixedly connected with a shaft base 54 by means of a rotary shaft 57, the upper portion of the shaft base 54 is fixedly connected with the bottom of the fishway body 1, and the shaft base 54 is rotationally connected with the top of the fixing frame 52.

[0038] Preferably, the adjusting structure 6 includes a moving plate 61, which is slidingly connected with the inner side wall of the fishway body 1, a plurality of racks 62 is fixed on the upper side of the moving plate 61, the rack 62 meshes with a gear 63, which is fixedly connected with the lower side of the auxiliary swimming board 21 by means of a fixing shaft 26, the lower side of the moving plate 61 is excavated with a groove fitting with a pushing rod 64 and a pushing column 66, respectively, the pushing rod 64 and the pushing column 66 are both articulated on the inner side wall of the fishway body 1, the lower side of the pushing rod 64 props against the top of a fixing rod 65, the lower side of the pushing column 66 props against a fixing column 67, and the fixing rod 65 and the pushing column 66 both pass through the thorough hole of the fishway body 1 and are fixed on the upper end of the fixing frame 52 of the floating dock structure 5.

[0039] Preferably, a third spring 68 is further arranged between the moving plate 61 and the fishway body 1.

[0040] In the technical scheme, while the auxiliary swimming board 21 is rotating and keeping itself tilted to push the sliding block 23 to slide, the roller 27 rolls on the upper surface of the moving plate 61, so that the roller 27 always props against the moving plate 61, avoiding the moving plate 61 from shaking. While the moving plate 61 is sliding up and down to push the gear 63 to rotate, the third spring 68 compresses to generate elastic force, enabling the moving plate 61 to stably slide.

[0041] The operating principle in this example is as follows. The fixing piece is put into the inside of the mounting hole 53, so that the fixing base 51 is fixed between the upstream and downstream, providing a support for the fishway body 1, and the water flows through the inner wall of the fishway body 1, thus the water overflows the auxiliary swimming board 21. The downstream fish swim into the inside of the fishway body 1 through the guiding board 4, and arrive at the top of the fishway body 1 through a plurality of auxiliary swimming boards 21 successively step by step, so that the fish swimming upstream through the auxiliary swimming board 21 can stay between the auxiliary swimming board 21 and the inner wall of the fishway body 1 to rest when they are exhausted. Furthermore, the auxiliary swimming board 21 set at an inclined upward angle can prevent the fish from washing downstream by a water flow during rest, and the upstream fish can wash directly downstream with a water flow through the fishway body 1. When the upstream and downstream levels defer from each other, the motor 55 runs under control, if the downstream water level rising and the upstream water level descending cause a drop between them to decrease, the motor 55 drives the rotatory shaft 57 to rotate, so that the shaft base 54 and the fishway body 1 rotate clockwise and the bottom and top of the fishway body 1 are in contact with the downstream and upstream having the decreased drop between them, ensuring that there exists the water flow inside the fishway body 1 for fish to migrate. For the same reason, if the downstream water level descending and the upstream water level rising cause a drop between them to increase, the motor 55 under the control drives the shaft base 54 and the fishway body 1 to rotate counterclockwise to avoid the fish from difficultly migrating as the water level rises over the fishway body 1, so as to adjust the fishway body 1 to assist the fish's migration. When the fishway body 1 rotates clockwise to adapt to the decrease in the water level drop, the pushing rod 64 rotates clockwise under the limit against the fixing rod 65 to push the moving plate 61 to slide upwards, so that the rack 62 slides upwards and drives the gear 63 to rotate counterclockwise and the auxiliary swimming board 21 rotates counterclockwise and maintains the original inclination angle to the horizontal plane. When the fishway body 1 rotates counterclockwise to adapt to the increase in the water level drop, the pushing column 66 rotates counterclockwise under the limit against the fixing column 67 to push the moving plate 61 and the rack 62 to slide downwards, so that the gear 63 rotates clockwise and the auxiliary swimming board 21 rotates clockwise and still maintains the original inclination angle to the horizontal plane, ensuring that the migratory fish have consistent physical output and maintain physical strength. The air pump 35 is energized to input the air into the air delivering pipe 32, so that the air enters a plurality of air inlet pipes 33 from the air delivering pipe 32, and enters the inside of the fishway body 1 through an unidirectional air outlet valve 34 for migratory fish to breathe, so this design is beneficial to fish's migration. The adjusting plate 37 connected with the auxiliary swimming board 21 props against the top block 36 of the side wall of the unidirectional air outlet valve 34 under the elastic force of the second spring 38, enhancing the firmness of the installation of the unidirectional air outlet valve 34 and avoiding it from loosening in the process of delivering oxygen to fish. During the rotation of the auxiliary swimming board 21, the second spring 38 extends to push the adjusting plate 37 against the top block 36, and when the second spring 38 compresses, the adjusting plate 37 still props against the top block 36. Thus, during the rotation of the auxiliary swimming board 21, this design ensures that the adjusting plate 37 always props against the top block 36 and the unidirectional air outlet valve 34 and avoids the unidirectional air outlet valve 34 from loosening, so as to help fish to breathe oxygen and keep physical strength for migration.
