[0002] Trash rack refers to the frame grid structure arranged in front of the water inlet for blocking water grass, driftwood and other sundries (generally referred to as pollutants) carried by water flow, which plays the function of filtering water body. For the current trash rack structure, the impurities on the trash rack will gradually increase after a period of use, blocking the trash rack. In order to ensure the normal work of the trash rack, it is necessary to carry out dredging work on the trash rack every certain period of time, so manual operation is required. However, when cleaning the trash rack, it is not possible to clean the position with deep water level, and only the position in the upper layer can be cleaned. Therefore, there is a problem of inconvenient cleaning and inability to clean the sundries in the deep water position. The existing dredging machine also has the defect of insufficient dredging intensity, which cannot meet the dredging requirements. Therefore, improvement is needed.

[0003] The Chinese utility model patent with authorization number CN 221741200 U provides a trash rack cleaning device for water conservancy projects, which comprises: two mounting seats, screw rods movably connected to the inner walls of the upper mounting seats, support rods fixedly connected to the inner walls of the lower mounting seats, two displacement blocks threadedly connected to one side of the outer surfaces of the screw rods, a cleaning device, the top end of the cleaning device being fixedly connected to the bottom ends of the two displacement blocks, the cleaning device comprising a connecting frame, a cleaning brush, a driver, a pad and a limiting plate, the cleaning brush being movably connected to the inner walls of the connecting frame, and a collecting mechanism, the collecting mechanism being installed in the cleaning device and comprising a collecting frame, a limiting tooth plate and a limiting column. The utility model cooperates the cleaning device and the collecting mechanism. After the cleaning brush cleans the impurities on the trash rack, the limiting tooth plate removes the impurities on the cleaning brush, avoiding the accumulation of impurities on the cleaning brush affecting the cleaning effect of the trash rack.

[0004] However, the above-mentioned trash rack cleaning device for water conservancy projects has the defect of insufficient dredging intensity of the existing dredging machine, which cannot meet the dredging requirements. Therefore, a solution is needed to improve this problem. UTILITY MODEL CONTENTS
