[0026] As shown in the figure, the rotating column 3 is rotatably connected in the protection box 1, and the first worm gear 4 is fixedly connected to the rotating column 3, and the rotating column 3 top end is fixed to the driving end of the motor 2, and the starting of the motor 2 makes the rotating column 3 can drive the first worm gear 4 to rotate in the protection box 1, and the protection box 1 is used to protect the components inside to avoid the damage corrosion of water vapor.

Figure 1 ​As shown; stabilizing blocks 16 are fixedly connected to both ends of the stop block 15, which allows the stabilizing blocks 16 to be fixed on the fishway bottom plate 11, preventing it from shaking. The stabilizing block 16 near the first fishway side plate 12 is fixedly connected to the first fishway side plate 12; the central column 9 passes through the two stabilizing blocks 16; the water flow plate 10 is disposed between the two stabilizing blocks 16.

[0027] like Figure 4 As shown, each stabilizing block 16 has a stabilizing groove 17 at its top, and the stabilizing groove is T-shaped; a fixing post 18 is fixedly connected through the interior of the stabilizing block 16 away from the first fishway side plate 12, as shown. Figures 5-6 As shown, a spring column 19 is slidably connected inside the fixed column 18. One end of the spring column 19 is fixedly connected to a locking column 20, which is slidably connected inside the stabilizing block 16. The other end of the spring column 19 is fixedly connected to a pulling column 21, which is located on the outside of the stabilizing block 16.

[0029] The working principle of this novel movable baffle-type fishway:

[0030] When water flow needs to be adjusted, the motor 2 inside the protection box 1 needs to be started, which drives the rotating column 3 to rotate. During this process, the rotating column 3 drives the first worm gear 4 to rotate inside the protection box 1. The first worm gear 4 drives the worm blade 6 to make the long column 5 rotate inside multiple adapter blocks 7, which makes the second worm gear 8, which is meshed with the worm blade 6, rotate. As a result, the central column 9 can also rotate, and the water flow plate 10 connected to the central column 9 can adjust its direction, so that the water flow plate 10 can be set to the required angle according to the water flow speed. Each central column 9 is fixed by two stabilizing blocks 16 to prevent shaking. Subsequently, when the garbage rack 22 slides into the stabilizing groove 17, it will squeeze the locking post 20, causing the spring post 19 to undergo elastic deformation inside the fixing post 18. The locking post 20 slides into the stabilizing block 16. When the garbage rack 22 is fully inside the stabilizing groove 17, it is locked in place. The garbage rack 22 uses the garbage net 23 to collect garbage into the interior when the water flows through it, thereby collecting garbage on the surface of the fishway. When the garbage is full, the locking post 20 can be pulled by the pulling post 21 to remove the locked garbage rack 22. When the pulling post 21 is released, the pulling post 21 can return to the set position due to the elastic deformation of the spring post 19, thereby enabling the quick installation and removal of the garbage rack 22, making the cleaning of collected garbage faster.
