[0027] When in use, multiple groups of rotating rollers 325 jointly support and position the cleaning belt 31, and stably install the cleaning belt 31 in the inner cavity of the fixed frame 1. The second rotating rod 322, the third rotating rod 323 and the fourth rotating rod 324 cooperate with each other to guide the cleaning belt 31 so that the cleaning belt 31 passes through the liquid storage chamber 2. The rotating assembly 34 controls multiple groups of first rotating rods 321 and second rotating rods 322 to rotate synchronously. The first rotating rod 321 and the second rotating rod 322 drive the rotating rollers 325 to rotate synchronously. Multiple groups of rotating rollers 325 can drive the cleaning belt 31 to rotate synchronously in the inner cavity of the fixed frame 1.

[0028] like Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the rotating assembly 34 includes a control box 341 fixedly installed on the side wall of the fixed frame 1, one end of the first rotating rod 321 and the second rotating rod 322 respectively extend into the control box 341 and are fixedly installed with a synchronous gear plate 342, and the surfaces of multiple groups of synchronous gear plates 342 are commonly meshed and connected with an annular synchronous belt 343, and a motor 344 is fixedly installed in the control box 341, and the output shaft of the motor 344 is connected to the end of a group of first rotating rods 321.

[0029] When in use, the motor 344 drives the first rotating rod 321 to rotate and then drives the synchronous gear plate 342 to rotate synchronously. The synchronous gear plate 342 cooperates with the synchronous belt 343 to drive multiple groups of synchronous gear plates 342 to rotate synchronously. The synchronous gear plate 342 drives multiple groups of first rotating rods 321 and second rotating rods 322 to rotate synchronously.

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, as a preferred embodiment of the present invention, the self-cleaning component 33 includes two groups of rotating columns 331 rotatably installed in the liquid storage chamber 2 and respectively located on both sides of the cleaning belt 31, and the surface of the rotating column 331 is provided with multiple groups of evenly distributed brushes 332 that cooperate with the cleaning belt 31, one end of the rotating column 331 extends to the outside of the fixed frame 1 and is fixedly installed with a fixed gear plate 333, one end of the fourth rotating rod 324 extends to the outside of the fixed frame 1 and is fixedly installed with a transmission gear plate 334, and the transmission gear plate 334 is meshed and connected with the fixed gear plate 333.

[0031] The fourth rotating rod 324 guides the cleaning belt 31 in the liquid storage chamber 2. When the cleaning belt 31 rotates in the inner cavity of the fixed frame 1, it can drive the fourth rotating rod 324 and the rotating roller 325 on its surface to rotate. The fourth rotating rod 324 drives the transmission gear plate 334 to rotate synchronously on the outside of the fixed frame 1. The transmission gear plate 334 and the fixed gear plate 333 are engaged for transmission, which can drive the rotating column 331 to rotate in the liquid storage chamber 2. The rotating column 331 drives the brush 332 to rotate on the outside of the cleaning belt 31. The brush 332 cooperates with the cleaning liquid in the inner cavity of the liquid storage chamber 2 to efficiently clean the oil stains on the surface of the cleaning belt 31.

[0032] like Figure 3 , Figure 4 , Figure 6 , Figure 8As shown, as a preferred embodiment of the present invention, the second positioning component 42 includes a plurality of vertical grooves 421 respectively opened on the two side walls opposite to each other in the inner cavity of the fixing frame 1, and sliding blocks 422 are slidably installed in the vertical grooves 421 along the vertical direction. The plurality of sliding blocks 422 on both sides of the inner cavity of the fixing frame 1 are commonly fixedly installed with a horizontal plate 423, and a plurality of connecting rods 424 are fixedly installed on the bottom wall of the horizontal plate 423, and the end of the connecting rod 424 away from the horizontal plate 423 is connected to the extrusion plate 41.

[0033] When in use, multiple groups of sliding blocks 422 support and position the horizontal plate 423. The sliding blocks 422 slide in the vertical direction in the vertical groove 421, and can control the horizontal plate 423 to move in the vertical direction in the inner cavity of the fixed frame 1. The horizontal plate 423 positions the extrusion plate 41 so that the extrusion plate 41 can move in the vertical direction. The horizontal plate 423 and the sliding blocks 422 push the extrusion plate 41 to move vertically downward under the action of gravity. The extrusion plate 41 applies a thrust to the cleaning belt 31, so that the cleaning belt 31 fits against the surface of the mechanical equipment.

[0034] like Figure 8 As shown, as a preferred embodiment of the present invention, a compression spring 5 is fixedly installed on the top of the vertical slot 421, and the telescopic end of the compression spring 5 is connected to the sliding block 422. The compression spring 5 applies a thrust to the sliding block 422, which can further increase the compression force on the compression plate 41.

[0035] like Figure 7 As shown, as a preferred embodiment of the present invention, two groups of squeezing rollers 6 are rotatably installed on the top of the liquid storage chamber 2, respectively on both sides of the cleaning belt 31. When the cleaning belt 31 moves from the liquid storage chamber 2 to the outside of the liquid storage chamber 2, the two groups of squeezing rollers 6 can squeeze and dehydrate the cleaned cleaning belt 31.

[0036] The working principle of the present invention is: when in use, multiple groups of rotating rollers 325 jointly support and position the cleaning belt 31, and stably install the cleaning belt 31 in the inner cavity of the fixed frame 1. The second rotating rod 322, the third rotating rod 323 and the fourth rotating rod 324 cooperate with each other to guide the cleaning belt 31, so that the cleaning belt 31 passes through the liquid storage chamber 2, and an appropriate amount of cleaning liquid is injected into the liquid storage chamber 2 through the liquid inlet pipe. The fixed frame 1 is placed on the surface of the mechanical equipment, and the hand-held handle 12 pushes the fixed frame 1 to move on the surface of the mechanical equipment. The horizontal plate 423 and the sliding block 422 push the extrusion plate 41 to move vertically downward under the action of gravity. The extrusion plate 41 applies thrust to the cleaning belt 31, so that the cleaning belt 31 and the surface of the mechanical equipment fit each other.

[0037] The motor 344 drives the first rotating rod 321 to rotate and then drives the synchronous toothed disc 342 to rotate synchronously. The synchronous toothed disc 342 cooperates with the synchronous belt 343 to drive multiple sets of synchronous toothed discs 342 to rotate synchronously. The synchronous toothed disc 342 drives multiple sets of first rotating rods 321 and second rotating rods 322 to rotate synchronously. The first rotating rod 321 and the second rotating rod 322 drive the rotating rollers 325 to rotate synchronously. Multiple sets of rotating rollers 325 can drive the cleaning belt 31 to rotate synchronously in the inner cavity of the fixed frame 1. When the cleaning belt 31 moves along the surface of the mechanical equipment, it can clean the oil on the surface of the mechanical equipment in all directions. The cleaning belt 31 wipes and absorbs the oil on the surface of the mechanical equipment.

[0038] The cleaning belt 31 rotates continuously. After the cleaning belt 31 that absorbs the oil stains moves into the liquid storage chamber 2, the fourth rotating rod 324 guides the cleaning belt 31 in the liquid storage chamber 2. When the cleaning belt 31 rotates in the inner cavity of the fixed frame 1, it can drive the fourth rotating rod 324 and the rotating roller 325 on its surface to rotate. The fourth rotating rod 324 drives the transmission gear disc 334 to rotate synchronously on the outside of the fixed frame 1. The transmission gear disc 334 and the fixed gear disc 333 are meshed and driven, which can drive the rotating column 331 to rotate in the liquid storage chamber 2. The rotating column 331 drives the brush 332 to rotate on the outside of the cleaning belt 31. The brush 332 cooperates with the cleaning liquid in the inner cavity of the liquid storage chamber 2 to efficiently clean the oil stains on the surface of the cleaning belt 31. After the oil stains on the surface of the cleaning belt 31 are cleaned, the cleaning belt 31 rotates and moves to the outside of the liquid storage chamber 2, and the oil stains on the surface of the mechanical equipment can be continuously wiped and cleaned.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
