The upper end of the fish protection frame 2 is detachably connected with a cover plate 7, and the cover plate 7 is used for blocking an upper end opening of the rotating shaft groove 25. The invention can facilitate the installation and the disassembly of the baffle plate 4 on the fish protection frame 2 by arranging the rotating shaft 41, the rotating shaft groove 25 and the cover plate 7, and is convenient for the production, the processing, the assembly and the transportation of the invention. The separator 4 is preferably made of a material having a density lower than that of water, such as PVC.

Each tension spring provides a tension between the baffle 3 and the base 5, the tension provided by each tension spring 5 acting to maintain the base shaft 41 in the bottom sleeve 32, preventing the bottom sleeve from falling off the base shaft. In addition, when the flow guiding disc 3 rotates relative to the base 1, when the water flow speed is unstable, the flow guiding disc 3 can rebound after rotating, and the rebound action is very beneficial to throwing out sediment and the like on the upper end face of the flow guiding disc 3, so that the effects of pollution discharge and sundries discharge are improved, and sediment and the like are prevented from being deposited below the fish protection frame. The bottom of the air deflector 3 is connected with an upper bolt 34, the upper end of the base 1 is connected with a lower bolt 12, the upper bolt 34 is used for connecting with the upper end of the extension spring 5, and the lower bolt 12 is used for connecting with the lower end of the extension spring.

The outer diameter of the locking sleeve 61 is larger than the diameter of the pin hole 13, and the locking sleeve 61 can swing in the through hole 35 along with the pin shaft 6. Each locking sleeve 61 is used to prevent the pin 61 from falling out of the pin bore 13 and the through bore 35. The perforations 35 cooperate with the latch means to prevent the bottom sleeve 32 from falling off the base shaft and to limit the extent to which the bottom sleeve 32 can rotate on the base shaft 41. During use, the sleeve nut 63 can be prevented from turning around by screwing on the pin 6. Each locking sleeve 61 is rotatably connected with a roller 64, the roller 64 penetrates through the through hole 35, and by arranging the roller 64, the smoothness of the relative movement of the bolt device in the through hole 35 can be improved, and smooth rotation of the guide disc is guaranteed.
