So the width of fan blade 7 that is arranged in positioning mechanism 4 changes for the spacing post 42 of fan blade 7 both sides takes place to remove, and spacing post 42 removes and drives locating lever 44 and remove in activity hole 411, because connect through positioning spring 43 between two locating levers 44, positioning spring 43 has elasticity, so the distance between two spacing posts 42 can change along with fan blade 7 width.
The positioning mechanism 4 can be kept tightly attached to the fan blade 7 in the cleaning process, so that the brushing mechanism 3, the cleaning solution feeding mechanism 5 and the wiping mechanism 6 cannot deviate from the position of the fan blade 7, and the surface of the fan blade 7 is cleaned.
The cleaning liquid feeding mechanism 5 above the brushing mechanism 3 sucks the cleaning liquid in the cleaning liquid containing box 51 through the feeding water pump 52 and sprays the cleaning liquid on the surface of the fan blade 7 to wet dirt on the fan blade 7, so that the fan blade 7 is conveniently brushed by the brushing mechanism 3, the brushing motor 37 in the brushing mechanism 3 drives the brushing transmission plate 36 to rotate around the rotating shaft of the brushing motor 37, the brushing transmission plate 36 rotates to drive the second transmission column 351 on the C-shaped transmission plate 35 to rotate around the rotating shaft of the brushing motor 37 while rotating, the second transmission column 351 rotates to drive the C-shaped transmission plate 35 to rotate, due to the limiting effect of the limiting bracket 33, the C-shaped transmission plate 35 rotates to drive the rotation column 32 to perform fan-shaped reciprocating rotation around the rotation column 32 and simultaneously to move back and forth along the central axis of the rotation column 32, so that the brush 31 at one end of the rotation column 32 rotates to clean the fan blade 7 and simultaneously moves back and forth towards the fan blade 7, because the surface of the fan blade 7 is a curved surface, the brush 31 moves back and forth towards the fan blade 7, so that the brush 31 can contact each part of the surface of the fan blade 7, no dead angle is left for cleaning, and the problem that the brush 31 cannot contact the concave position of the fan blade 7 to cause incomplete cleaning due to the certain distance between the brush 31 and the fan blade 7 is avoided.
After the washing, dirt on fan blade 7 is dissolved in the cleaning solution and flows down along fan blade 7, and the sewage that flows down contacts the sponge body 61 who pastes with fan blade 7 mutually, and sponge body 61 absorbs the sewage that flows down internally, and after having washd a period, sponge body 61 absorbs behind a certain amount of sewage, and cleaning solution feed mechanism 5 stops spraying the cleaning solution.
The working box 2 stops moving, the sponge driving motor 64 is driven to enable the sponge body 61 to be close to the extrusion plate 65, the sponge casing 62 is located below the sponge body 61, the extrusion plate 65 extrudes the sewage absorbed in the sponge body 61, the sewage falls into the liquid receiving box 66 through the liquid flowing through hole 621, the sewage in the liquid receiving box 66 is absorbed into the sewage collecting box 68 through a water pipe by the suction force of the liquid outlet pump 67, after the extrusion operation is completed, the sponge body 61 is driven to reset by the sponge driving motor 64, the water content of the sponge body 61 is lower at the moment, the sewage can be continuously absorbed, the sponge body 61 is arranged to wipe the moisture on the fan blade 7, the fan blade 7 can be prevented from being corroded and rusted by the residual moisture and the components of the cleaning solution, the sewage is absorbed into the sewage collecting box 68 for centralized collection by the arrangement of the liquid outlet pump 67, and the sewage is prevented from directly falling into the environment, and the environment around the power generation fan is polluted.
The above description is only an example of the present invention and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
