At the same time, the winch cooperates with the connecting plate 4 so that the mounting frame 1 can be fixed on the crawler mobile vehicle, so that the mounting frame 1 can be installed with large cleaning equipment to facilitate the cleaning of the dam.

[0091] The mounting frame 1 of the present invention includes a first rectangular frame 27, a second rectangular frame 28 arranged at the bottom of the first rectangular frame 27, and a third rectangular frame 30 respectively arranged at the two ends of the bottom of the second rectangular frame. The connecting frame 24 is respectively connected to the first rectangular frame 27, the second rectangular frame 28 and the third rectangular frame 30. The driving clearance groove 12 and the transmission clearance groove 13 are opened on the first rectangular frame 27. The driving motor 7 is installed on the first rectangular frame 27. The clearance groove 2 is opened on the two side walls of the second rectangular frame 28. The slide groove 21 is opened on the inner walls of the two sides of the second rectangular frame 28. A plurality of reinforcing rods 31 are arranged in the second rectangular frame 28. A connecting oblique rod 32 is arranged between two adjacent reinforcing rods 31. The connecting oblique rod 32 and the reinforcing rod 31 can effectively enhance the rigidity of the second rectangular frame 28, thereby facilitating the first rectangular frame 28 to support the cleaning equipment.

[0092] The crawler-type mobile vehicle, cleaning equipment, winch and drive motor 7 used in the present invention are all existing technologies and can be directly purchased and used on the market. Therefore, the structure, circuit and principle of the crawler-type mobile vehicle, cleaning equipment, winch and drive motor 7 are not described here in detail.
