Moreover, in the cleaning apparatus of the present embodiment, since the height of the spray pipe 43 can be adjusted by the height adjusting frame 42 in the shaft hole cleaning device 4, the wind power main shaft with different diameters can be adapted, the larger the shaft diameter of the wind power main shaft is, the higher the shaft hole height at the shaft center of the wind power main shaft is, the height of the shaft hole of the wind power main shaft can be adapted only by raising the spray pipe 43 by using the height adjusting frame 42, and the use flexibility of the cleaning apparatus of the present embodiment is further improved.
Furthermore, in the cleaning apparatus of the present embodiment, since the movable seat 41 in the shaft hole cleaning device 4 can move along the axial direction of the wind power spindle, when the wind power spindle has no shaft hole, the movable seat 41 can be moved away to avoid the spray pipe 43 from interfering with the lifting of the wind power spindle, and when the wind power spindle is provided with the shaft hole, the movable seat 41 can be moved closer to extend the spray pipe 43 into the shaft hole for flushing. Therefore, the cleaning equipment of the embodiment can adapt to the wind power main shaft with and without the shaft hole, and the use flexibility of the cleaning equipment of the embodiment is further improved.

The drive mechanism 24 includes a drive base 245, a drive motor 246, a primary sprocket 247, a secondary sprocket 248, and a drive chain 249. The driving seat 245 is fixedly arranged above the middle of the left rotating seat 23 and the right rotating seat 23, the driving seat 245 is fixedly provided with a driving motor 246, the driving motor 246 can adopt a servo motor, the output shaft of the driving motor 246 is fixedly provided with two main chain wheels 247, the left rotating shaft 21 and the right rotating shaft 21 are fixedly provided with a secondary chain wheel 248, and the main chain wheel 247 is connected with the secondary chain wheel 248 through a transmission chain 249.
As shown in fig. 6, when the driving motor 246 drives the two main chain sprockets 247 to rotate clockwise together, each main chain sprocket 247 drives one sub chain sprocket 248 to rotate clockwise through the transmission chain 249, so that the two sub chain sprockets 248 rotate in the same direction, thereby rotating the left and right rotary shafts 21 in the same direction, and further rotating the left and right rotary rollers 22 in the same direction.
When the wind power main shaft is lifted to the left and right rotating rollers 22, the wind power main shaft supported by the left and right rotating rollers 22 is rotated by friction between the wind power main shaft and the rotating rollers 22 when the left and right rotating rollers 22 are rotated in the same direction. Thereby realizing the function of the rotating device 2 for supporting the wind power main shaft to rotate.
As can be seen from the above description, the first structural form of the driving mechanism 24 provided in embodiment 1 and the second structural form of the driving mechanism 24 provided in embodiment 2 can both drive the left and right rotating rollers 22 to rotate in the same direction.
In addition, both the driving mechanism 24 in embodiment 1 and the driving mechanism 24 in embodiment 2 can drive the two rotating rollers 22 to rotate by using one motor device (the transmission motor 242/the driving motor 246), so that the number of motor devices is reduced, the overhaul and maintenance intensity of the motor devices is reduced, and the labor intensity of workers is reduced.
Example 3:

When the driving telescopic piece 2411 is extended, the driving seat 245 is pushed up by the driving telescopic piece 2411, and when the driving telescopic piece 2411 is shortened, the driving seat 245 is driven by the driving telescopic piece 2411 to move downwards.
And, as shown in fig. 7 to 10, two left and right swivel seats 23 located at both front and rear sides of the washing tub 1 can slide left and right on the upper edge of the washing tub 1.
Also, as shown in fig. 7 to 10, the driving mechanism 24 further includes a distance adjusting lever 2412, an upper end of the distance adjusting lever 2412 is rotatably connected to an output shaft of the driving motor 246, and a lower end of the distance adjusting lever 2412 is rotatably connected to the rotation shaft 21.
When the height of the driving seat 245 is increased, the driving motor 246 and the main chain 247 on the driving seat 245 are increased along with the driving seat, the driving motor 246 drives the upper ends of the distance adjusting rods 2412 to be increased, so that the included angle between the left distance adjusting rod 2412 and the right distance adjusting rod 2412 is reduced, the distance between the lower ends of the two distance adjusting rods 2412 is reduced, the distance between the rotating seats 23 at the left side and the right side is reduced, and then the distance between the two rotating rollers 22 at the left side and the right side is reduced.

In the process of lifting the driving seat 245, each distance adjusting rod 2412 can maintain the distance between the output shaft of the driving motor 246 and the rotating shaft 21, so that the opened state of the driving chain 249 can be maintained, and then the main sprocket 247 can continuously drive the auxiliary sprocket 248 to rotate.
When the wind power main shaft is only washed, the residual oil stain rate on the surface of the wind power main shaft is increased, so that in order to thoroughly wash the oil stain on the surface of the wind power main shaft, the operation can be carried out by (1) using hoisting equipment, such as a crane, by workers to hoist the two ends of the wind power main shaft. (2) The worker lowers the height of the driving seat 245 so that the distance between the left and right rotating rollers 22 increases, and does not stop lowering the height of the driving seat 245 until the distance between the left and right rotating rollers 22 is enough to allow the wind power main shaft to pass downward. (3) The worker uses the traveling crane to hang down the wind power main shaft, so that the wind power main shaft is immersed in the cleaning pool 1, alkaline cleaning agents are poured into the cleaning pool 1, oil stains on the surface of the wind power main shaft can fully react with the cleaning agents, the effect of removing the oil stains is improved, and the cleaning effect of the wind power main shaft is improved.
After the oil stains on the surface of the wind power main shaft are cleaned, the wind power main shaft can be lifted out of the cleaning pool 1 by using a crane, a worker lifts the height of the driving seat 245 again, the left rotating roller 22 and the right rotating roller 22 are close to each other, then the wind power main shaft is placed on the left rotating roller 22 and the right rotating roller 22, and residual cleaning agent on the wind power main shaft is cleaned by using the side wall cleaning device 3 and the shaft hole cleaning device 4.
As can be seen from the above-described process, the distance between the two rotating rollers 22 can be adjusted by adjusting the height of the driving seat 245, horizontally sliding the rotating seat 23 in the left-right direction with the upper edge of the washing tub 1, and providing the distance adjusting lever 2412 while driving the two rotating rollers 22 to rotate by one driving motor 246. On the one hand, the number of motor equipment can be reduced, the strength of motor equipment overhaul and maintenance is reduced, on the other hand, when the distance between the two rotary rollers 22 is increased, the wind power main shaft is allowed to penetrate through the two rotary rollers 22 and submerge in the cleaning pool 1, and the wind power main shaft is subjected to oil removal soaking of alkaline cleaning agents, so that the cleaning effect of the wind power main shaft is improved.
Unexpectedly, when the height of the spray pipe 43 cannot be adjusted due to damage to the height adjusting bracket 42 in the shaft hole cleaning device 4, the distance between the two rotating rollers 22 can be adjusted, so that the height of the wind power main shaft positioned on the two rotating rollers 22 can be adjusted to adapt to the height of the spray pipe 43 which cannot be adjusted. The larger the distance between the two rotating rollers 22 is, the lower the axial height of the wind power main shaft is, and the smaller the distance between the two rotating rollers 22 is, the higher the axial height of the wind power main shaft is. Therefore, the spray washing pipe 43 can be inserted into shaft holes with different heights to be washed, the use flexibility of the washing equipment of the embodiment is improved, and the emergency reaction capability of the washing equipment of the embodiment is further improved.
As shown in fig. 11, when the distance between the two rotating rollers 22 increases from L1 to L2, the axial height of the wind power main shaft 01 decreases by H.
Example 4:
this example 4 is a further improvement over example 3:
As shown in fig. 12, when the wind power main shaft 01 is soaked in the cleaning tank 1, in order to increase the contact area between the wind power main shaft 01 and the cleaning agent, to improve the cleaning effect on the wind power main shaft 01, a plurality of annular grooves 221 are formed in the rotating roller 22, so that the cleaning agent in the cleaning tank 1 can flow in the annular grooves 221, the contact area between the wind power main shaft 01 and the rotating roller 22 is reduced, the contact area between the wind power main shaft 01 and the cleaning agent is increased, the soaking effect of the wind power main shaft 01 is improved, and further, oil stains on the surface of the wind power main shaft 01 are removed more thoroughly, and further, the cleaning effect on the wind power main shaft 01 is improved.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
