DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Please refer to the attached Figure 1-5 The utility model provides a grille dirt removal device, including a lifting rod 1, which is used to connect the device to a pulley device. It should be noted that the pulley device is a lifting or lowering device composed of a wire rope, a drum, and a motor reducer, which is a well-known technology for those skilled in the art. Triangular plates 2 are symmetrically fixed at both ends of the lifting rod 1. A straight-toothed rake 3 with a plurality of straight teeth is fixed at the rear end of the bottom of the triangular plate 2. A curved-toothed rake 4 with a plurality of curved teeth is hingedly connected at the front end of the bottom of the triangular plate 2. A connecting seat 5 is fixed at the middle of the top of the straight-toothed rake 3. A cylinder 6 is hinged on the connecting seat 5. A lever arm 7 is fixed at the middle of the top of the curved-toothed rake 4. The front end of the output shaft of the cylinder 6 is rotatably connected to the top of the lever arm 7. Therefore, when the cylinder 6 is running, the curved-toothed rake 4 can be driven by the lever arm 7 to rotate clockwise or counterclockwise, thereby controlling the curved-toothed rake 4 to move toward the straight-toothed rake 3 (rotating counterclockwise, such as Figure 4 As shown), garbage can be grabbed, and when the curved tooth rake 4 is controlled to move away from the straight tooth rake 3 (clockwise rotation), the grabbed garbage can be dumped, and the front end of the straight tooth rake 3 is provided with an inner buckle component 1, and the rear end of the curved tooth rake 4 is provided with an inner buckle component 2;

[0022] The inner buckle component 1 includes a plurality of rotating teeth 8, and the plurality of rotating teeth 8 correspond to the plurality of spur teeth on the spur tooth rake 3 one by one. The top ends of the rotating teeth 8 are hinged at the corresponding front ends of the spur teeth. The middle of the spur tooth rake 3 is rotatably connected with an oil cylinder 29, and a connecting rod 10 is laterally fixed to the lower side of the front ends of the plurality of rotating teeth 8. Therefore, under the action of the connecting rod 10, the plurality of rotating teeth 8 can be connected to achieve the purpose of synchronous rotation. The middle of the connecting rod 10 is rotatably connected with the bottom end of the output shaft of the oil cylinder 29. Specifically, when the oil cylinder 29 is running, the connecting rod 10 can be used to control the plurality of rotating teeth 8 to rotate clockwise or counterclockwise synchronously. When the oil cylinder 29 drives the plurality of rotating teeth 8 to rotate clockwise through the connecting rod 10 (such as Figure 5 As shown), an inner buckle structure can be formed on the inner side of the straight tooth rake 3 and the curved tooth rake 4;

[0023] The inner buckle component 2 includes a plurality of rotating teeth 2 11, and the plurality of rotating teeth 2 11 correspond to the plurality of curved teeth on the curved tooth rake 4 one by one. The top ends of the rotating teeth 2 11 are hinged at the corresponding rear ends of the curved teeth. The middle of the curved tooth rake 4 is rotatably connected with an oil cylinder 3 12. A connecting rod 2 13 is laterally fixed to the lower side of the rear ends of the plurality of rotating teeth 2 11. Therefore, under the action of the connecting rod 2 13, the plurality of rotating teeth 2 11 can be connected to achieve the purpose of synchronous rotation. The middle of the connecting rod 2 13 is rotatably connected to the bottom end of the output shaft of the oil cylinder 3 12. Specifically, when the oil cylinder 3 12 is running, the connecting rod 2 13 can be used to control the plurality of rotating teeth 2 11 to rotate clockwise or counterclockwise synchronously. When the oil cylinder 3 12 drives the plurality of rotating teeth 2 11 to rotate counterclockwise through the connecting rod 2 13 (such as Figure 5 As shown in the figure, an inner buckle structure can be formed again on the inner side of the straight tooth rake 3 and the curved tooth rake 4, that is, the device has the function of grabbing garbage, that is, removing dirt, and can also further improve the firmness of grabbing garbage by forming two interacting inner buckle structures on the inner side of the straight tooth rake 3 and the curved tooth rake 1, so that the garbage can be grabbed more cleanly, thereby effectively improving the decontamination effect;

[0024] A support rod 14 is fixed to the side of the triangular plate 2, and a roller 15 is rotatably connected to the rear end of the support rod 14, so that the device can rise and fall more smoothly at the water intake of a hydropower station, a water treatment plant, a water plant, an electric drainage station, a pumping station, etc.

[0025] The use process of the utility model is as follows: when it is necessary to grab garbage, the device can be first dropped to the water inlet through the pulley device, and then the oil cylinder 1 6 operates to control the curved tooth rake 4 to rotate toward the straight tooth rake 3, and at the same time, the oil cylinder 2 9 operates through the connecting rod 10 to drive the plurality of rotating teeth 1 8 to rotate clockwise, and the oil cylinder 3 12 operates through the connecting rod 2 13 to drive the plurality of rotating teeth 2 11 to rotate counterclockwise (such as Figure 5 As shown), the garbage can be grabbed, and when the oil cylinder 2 9 drives the rotating teeth 1 8 to rotate clockwise through the connecting rod 1 10, an inner buckle structure is formed inside the straight tooth rake 3 and the curved tooth rake 4, and when the oil cylinder 3 12 drives the rotating teeth 2 11 to rotate counterclockwise through the connecting rod 2 13, an inner buckle structure is formed again inside the straight tooth rake 3 and the curved tooth rake 4. That is, the device has the function of grabbing garbage, that is, decontamination, and can further improve the firmness of garbage grabbing by forming two interacting inner buckle structures on the inner sides of the straight tooth rake 3 and the curved tooth rake 1, so that the garbage can be grabbed more cleanly, thereby effectively improving the decontamination effect.

[0026] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
