[0028] like Figure 4-5 As shown, the mobile fixing mechanism 9 includes a U-shaped plate 901 fixedly connected to the inner wall of the mounting frame 1, a bidirectional screw 902 is rotatably connected between the inner walls of the U-shaped plate 901, and the outer wall of the bidirectional screw 902 is provided with a pair of external threads, and the directions of the pair of external threads are opposite, a second motor 903 is installed on the top of the U-shaped plate 901, and the output end of the second motor 903 is fixedly connected to the top of the bidirectional screw 902, a pair of transmission nuts 904 are threadedly connected to the outer wall of the bidirectional screw 902, and a second electric telescopic rod 905 is installed on the end of the pair of transmission nuts 904 away from the U-shaped plate 901, and the end of the pair of second electric telescopic rods 905 away from the transmission nut 904 is fixed It is connected to a circular plate 906, and the end of the circular plate 906 away from the second electric telescopic rod 905 is rotatably connected to a connecting bent rod 907, the ends of a pair of connecting bent rods 907 that are close to each other are fixedly connected to a connecting plate 908, and the outer walls of a pair of connecting plates 908 are installed with clamps 909 by bolts, and a rotation reversing mechanism 10 is installed between the outer wall of the connecting bent rod 907 and the end of the circular plate 906 close to the connecting bent rod 907, a pair of transmission nuts 904 are fixedly connected to a slider 9041 at one end away from the second electric telescopic rod 905, a sliding groove 9042 is carved on the inner wall of the U-shaped plate 901, and a pair of sliders 9041 are both located in the sliding groove 9042 and are slidably connected thereto.

[0029] When in use, a pair of second electric telescopic rods 905 respectively drive a pair of circular plates 906, a connecting bent rod 907 and a clamp 909 to perform telescopic movements, so that the position of the clamp 909 corresponds to the inner wall or outer wall of the floating oil seal, so that the clamp 909 can subsequently clamp and fix the inner wall or outer wall of the floating oil seal. Then the second motor 903 drives the bidirectional screw 902 to rotate, so that it drives a pair of transmission nuts 904 to move toward or away from each other, so that it drives a pair of clamps 909 to move toward or away from each other, clamping and fixing the inner wall or outer wall of the floating oil seal, so that it can remain stable during the cleaning process, and the clamp 909 can be easily disassembled through the detachable bolt installation method, so that the corresponding clamp 909 can be replaced according to the size of the floating oil seal.

[0030] like Figure 4 and Figure 6 As shown, a pair of rotation reversing mechanisms 10 each include a movable plate 1001 sleeved on the outer wall of the connecting bent rod 907, and the end of the movable plate 1001 away from the circular plate 906 is threadedly connected with a locking bolt 1002, and the end of the circular plate 906 close to the connecting bent rod 907 is chiseled with a pair of bolt fixing grooves 1003, and the locking bolts 1002 are connected to the bolt fixing grooves 1003. When a pair of clamps 909 need to clamp the inner wall of the floating oil seal, the movable plate 1001 and the connecting bent rod 907 are moved to drive the clamping direction of the clamp 909 to rotate upward, and when a pair of clamps 909 need to clamp the outer wall of the floating oil seal, the movable plate 1001 and the connecting bent rod 907 are moved to drive the clamping direction of the clamp 909 to rotate downward, and then the clamp is locked and fixed by the locking bolt 1002 and the bolt fixing groove 1003, thereby clamping and fixing the inner wall or outer wall of the floating oil seal.

Through the setting of the filter screen plate 12, impurities in the cleaning liquid can be filtered to facilitate the subsequent recycling of the collected cleaning liquid.

[0032] The working principle of the utility model is as follows: first, the outer wall of the floating oil seal is cleaned, and the movable plate 1001 and the connecting bent rod 907 are moved to drive the clamp 909 to rotate 180 degrees, so that the clamping direction of the clamp 909 rotates downward, and then a pair of second electric telescopic rods 905 respectively drive a pair of circular plates 906, the connecting bent rod 907 and the clamp 909 to perform telescopic movement, so that the position of the clamp 909 corresponds to the outer wall of the floating oil seal;

[0033] Next, the second motor 903 drives the bidirectional screw 902 to rotate, which in turn drives the pair of drive nuts 904 to move toward each other. The pair of drive nuts 904 drive the clamp 909 and the connecting bent rod 907 to move toward each other via the second electric telescopic rod 905 and the circular plate 906, and come into contact with the outer wall of the floating oil seal, thereby clamping and fixing the outer wall of the floating oil seal.

[0034] Then, the first electric telescopic rod 804 drives the liquid storage tank 2, the small water pump 3, the liquid spraying pipe 5, and the annular cleaning wiper 6 to perform telescopic movement, so that the positions of the liquid spraying pipe 5 and the annular cleaning wiper 6 correspond to the outer wall of the floating oil seal. Simultaneously, the slide cylinder 803 drives the liquid spraying pipe 5 and the annular cleaning wiper 6 to perform linear movement, so that the annular cleaning wiper 6 contacts the outer wall of the floating oil seal.

[0035] Next, the small water pump 3 draws the cleaning liquid from the liquid storage tank 2 through the liquid extraction pipe 4 and discharges it outward through the liquid spray pipe 5. At the same time, the first motor 802 cooperates with the rotating disk 801 to drive the liquid spray pipe 5 and the annular cleaning wiper 6 to perform a circular motion along the inner or outer wall of the floating oil seal, spraying liquid and wiping at the same time, thereby achieving a thorough cleaning of the outer wall of the floating oil seal.

[0036] After the outer wall is cleaned, the inner wall of the floating oil seal needs to be cleaned. The movable plate 1001 and the connecting bent rod 907 are moved to drive the clamp 909 to rotate 180° so that the clamping direction of the clamp 909 rotates upward, and the above operation is repeated to clean the inner wall of the floating oil seal, reduce the residual impurities, and enhance the cleaning effect.

[0037] The wiring diagram of the small water pump 3, the first motor 802, the sliding rod cylinder 803, the first electric telescopic rod 804, the second motor 903 and the second electric telescopic rod 905 in this solution is common knowledge in the field.
