[0011] Efficiently remove the sludge and algae on the surface of the trash rack: By arranging sliders and cleaning cones on the trash rack, the sludge and adhered algae on the surface of the grid bars can be effectively removed, the grid bars can be kept clean, and the trash interception effect can be improved. By arranging the support rod between two adjacent grid bars, the gap size of the trash rack can be adjusted to adapt to pollutants of different sizes and types, thereby improving the interception effect and reducing siltation. The stepper motor drives the lead screw and the movable plate thread transmission to achieve vertical movement of the movable plate along the guide rail, so that the cleaning cone can automatically remove the sludge and algae on the surface of the grid bars, reducing the labor intensity of manual cleaning. Due to the lifting and lowering adjustment function of the movable plate and the support rod, it can effectively prevent pollutants from gathering in front of the trash rack to form a siltation area, keep the river channel unobstructed, and improve the self-purification capacity of the water body.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a trash rack for river purification, comprising a bottom plate 1, a top plate 2 and grid bars 3, the top plate 2 is located at the top of the bottom plate 1, the grid bars 3 are horizontally welded between the bottom plate 1 and the top plate 2 at equal intervals, the outer surface of the grid bars 3 is slidably connected with a slider 6, the upper and lower ends of the slider 6 are movably installed with cleaning cone blocks 7, the cleaning cone block 7 is slidably matched with the grid bars 3, the outer surface of one end of the slider 6 is connected with a support rod 5, and the other end of the support rod 5 is connected with a movable plate 4.

[0018] The top of the top plate 2 is symmetrically provided with guide rails 12, and the other end of the guide rails 12 is fixedly connected with a mounting frame 9. The guide rails 12 are arranged between the top plate 2 and the mounting frame 9, which can enhance the stability of the overall structure and ensure that the movable plate 4 will not deviate during the vertical movement process, thereby increasing the movement resistance.

[0019] A stepper motor 10 is installed at the middle end of the top surface of the mounting frame 9, and a lead screw 11 is connected to the output end of the stepper motor 10. The stepper motor 10 drives the lead screw 11 to rotate in positive and reverse directions. The lead screw 11 and the movable plate 4 are threadedly transmitted, thereby controlling the lifting and lowering of the movable plate 4.

[0020] The screw rod 11 is movably connected to the mounting frame 9, and the screw rod 11 is movably connected to the top plate 2. The screw rod 11 is movably connected to the mounting frame 9 and the top plate 2, which ensures that the screw rod 11 will not be obstructed while ensuring the stability of the rotation of the screw rod 11, thereby ensuring the transmission efficiency of the screw rod 11 and the movable plate 4.

[0021] The movable plate 4 is threadedly connected to the screw rod 11, and the movable plate 4 is slidably connected to the guide rail 12.
