The current wall climbing robot can climb through the magnetic device, and the working face is cleaned through the disc brush, such as flushing and wiping, and the scheme can realize effective planar cleaning. To the washing of curved surface, if adopt foretell wall climbing robot to wash the curved surface through the disc brush, because the curved surface exists the radian, the unable fine laminating with the curved surface in disc brush both ends during the washing, cleaning mechanism can't adjust the dynamics of cleaning, leads to cleaning performance poor, inefficiency. In some technologies, the cleaning of the curved surface is realized by replacing the disc brush of the wall climbing robot with an arc-shaped structure, but the radian is fixed, and the cleaning can be only performed on the curved surface with the set curvature radius, so that the application range is small.

Therefore, the cleaning work of the tower is very important, and most of the cleaning work is finished by manual high-altitude cleaning work at present, and operators attach to the tower to manually clean the tower through hoisting ropes, so that the problems of low cleaning efficiency, long cleaning period, high risk coefficient, low safety, high labor intensity, high labor cost, high cleaning cost and the like exist. In some schemes, the wall climbing robot is adopted for cleaning, and because the existing wall climbing robot cleans a working surface with a consistent plane or curvature radius, the cleaning device cannot adapt to curved surfaces with different curvature radii, so that the cleaning device cannot effectively fit with the curved surfaces of the tower barrel for cleaning, and the cleaning force is difficult to adapt to the curved surfaces with different curvature radii, so that the problems of poor cleaning effect, small cleaning area, low cleaning efficiency and the like are caused.

At present, the wall climbing robot cleans greasy dirt on the surface of a wind power tower through a disc brush, and is difficult to effectively clean curved surfaces with different curvature radiuses. Taking the outer wall cleaning of a tower as an example (such as a wind power tower), the tower is generally in a cylindrical structure with a small top and a large bottom, and the curvature radius of the tower is gradually increased from top to bottom so as to ensure the stability of the support. Because the outer wall of the tower cylinder is a curved surface, radian exists, and if the tower cylinder cannot be well attached to the outer wall of the tower cylinder during cleaning, the cleaning force is uneven, and the cleaning effect is difficult to ensure. Moreover, the curvature of the outer wall of the tower barrel changes, and the conventional cleaning mechanism cannot adjust the cleaning force, so that the cleaning effect is poor and the efficiency is low. Currently, in addition to the aforementioned cleaning methods, some cleaning solutions for towers are provided in the prior art, for example:
1. chinese patent application No. (publication No. CN 110201956A) discloses a tower cleaning device, which pushes a roller brush to move back and forth through a cylinder so as to adapt to the change of the taper of the tower in the up-down direction. The problem that this scheme exists is, in the cleaning process, need take corresponding sensing means and control means, through the feedback control mode of collocation, detect the back and the removal of accurate control cylinder to the curved surface of tower section of thick bamboo, just can make the cylinder brush carry out the washing of tower section of thick bamboo along with tower section of thick bamboo diameter variation, the cylinder brush does not possess self-adaptation adjustment ability.
2. Chinese patent application "curved surface running gear and magnetic force cleaning robot thereof" (publication number: CN 110341828A), disclosed a curved surface running gear and magnetic force cleaning robot thereof, the device adapts to working surfaces with different curvature radius through the curved surface running gear, and realizes the radial and tangential position adjustment of the cleaning brush through bolt adjustment, so as to adapt to the curvature of the working surfaces. The problem that this scheme exists is, the regulation of brush cleaner need debug before the cleaning operation, and belt cleaning device walks and carries out abluent in-process on the curved surface, and cleaning device's brush cleaner can't self-adaptation adjust the dynamics of cleaning.
The two tower barrel cleaning schemes listed above all have the problems that the cleaning device cannot adapt to the change of the curved surface of the tower barrel and cannot automatically adjust the cleaning force, so that the cleaning effect is poor and the cleaning efficiency is low. The application provides a wiping mechanism and belt cleaning device can adapt to the curved surface that radius of curvature is different, improves the wiping efficiency of treating the cleaning surface, helps optimizing the cleaning performance, improves cleaning efficiency. Embodiments of the present application are described below in conjunction with fig. 1-10:
fig. 1 is a schematic structural diagram of a wiping mechanism according to an embodiment of the present application, referring to fig. 1, an embodiment of a first aspect of the present application provides a wiping mechanism 100, which includes a wiping support 101 and a wiping rope 102, and the wiping rope 102 is attached to a working surface to be cleaned and moves along a set direction, so that moisture on the working surface can be wiped.
The wiping bracket 101 comprises a fixing frame 103, an adjusting component 104 and a guide piece 105, wherein the fixing frame 103 is provided with a set length along a first direction, the adjusting component 104 is connected to the fixing frame 103, the guide piece 105 is respectively arranged on two sides of the adjusting component 104, and the guide piece 105 is connected to the fixing frame 103. In addition, the guide member 105 is further away from the fixing frame 103 relative to the adjusting assembly 104 along the second direction, and two ends of the wiping cord 102 are respectively connected to the adjusting assembly 104 and wound around the guide member 105 along the first direction. Under the action of external force, the wiping cord 102 can slide relative to the guide members 105 to be loosened or tensioned between the two guide members 105 along the second direction, the adjusting assembly 104 is located between the two guide members 105 and used for tensioning the wiping cord 102 along the second direction, and the second direction is perpendicular to the first direction, so that the wiping cord 102 can adapt to a curved surface with a larger or smaller fitting curvature and adaptively tensioning the working surface being wiped, and the wiping and cleaning force is ensured.
In the process of attaching and wiping the working surface to be cleaned by the wiping rope 102: when the curvature radius of the curved surface through which the wiping cord 102 passes becomes larger, the wiping cord 102 is squeezed to be loosened from between the two guide members 105 to adapt to the increase of the curvature radius of the working surface to be cleaned, and meanwhile, the adjusting assembly 104 can enable the wiping cord 102 to be tensioned to be attached to the working surface to be cleaned, so that the wiping cleaning force can be adaptively adjusted. Conversely, when the radius of curvature of the curved surface through which the wiping rope 102 passes becomes smaller, the adjusting component 104 can make the wiping rope 102 tighten to fit the working surface to be cleaned so as to adapt to the reduction of the radius of curvature of the working surface to be cleaned, so that the wiping rope 102 is prevented from being loosened to separate from the working surface to be cleaned or weakening the wiping force, and the wiping force is adjusted adaptively.
Fig. 2 is an enlarged view of a portion of fig. 1, showing a specific structure of the guide member 105, referring to fig. 2, in some embodiments, the guide member 105 may include a first pulley 106, a second pulley 107, a first connecting rod 108 and a second connecting rod 109, wherein the first connecting rod 108 extends along a first direction, one end is connected to the fixing frame 103, the other end is connected to the first pulley 106, the second connecting rod 109 extends along a second direction, one end is connected to the first connecting rod 108, and the other end is connected to the second pulley 107. The two guides 105 are symmetrically arranged. Thus, in the second direction, the second pulley 107 is further away from the fixing frame 103 relative to the adjusting assembly 104, and the wiping cord 102 is wound around the first pulley 106 and the second pulley 107, so that there can be a movement space in the second direction, thereby facilitating loosening or tightening as the curvature of the working surface to be cleaned changes. The first pulley 106 and the second pulley 107 provide guiding and friction reduction of the drying line 102.
In some embodiments of the wiping mechanism 100, the adjusting assembly 104 may include two elastic members 110, where one end of each of the two elastic members 110 is connected to the fixing frame 103, and the other end of each of the two elastic members is connected to two ends of the wiping rope 102, so that the wiping rope 102 can be adaptively loosened or tightened along with the change of the curvature radius of the curved surface under the traction of the elastic member 110, and is kept close to the curved surface under the elastic force of the elastic member 110, thereby ensuring the cleaning force.
Fig. 3 is an enlarged view of a portion B of fig. 1, showing a specific structure of the adjusting assembly 104, referring to fig. 3, in the wiping mechanism 100 of some embodiments, the adjusting assembly 104 may also include a swing rod 111 and an elastic member 110, where one end of the elastic member 110 is connected to the fixing frame 103, and the other end is connected to the swing rod 111. Along the first direction, two sides of the elastic member 110 are respectively provided with a swinging rod 111, one end of the swinging rod 111 is rotatably connected with the fixing frame 103, and the other end of the swinging rod 111 is connected with the wiping rope 102. The elastic member 110 may be a compression spring. Therefore, in the process of wiping and cleaning the curved surface, when the curvature radius of the curved surface is increased, the wiping and drying rope 102 can draw the swinging rod 111 to swing along the first direction so as to be away from each other, the length of the wiping and drying rope 102 for attaching the curved surface is increased, so that the curved surface can be attached, the swinging of the swinging rod 111 drives the elastic element 110 to elastically deform, the restoring force of the elastic element 110 can enable the swinging rod 111 to swing towards the direction close to each other, and thus the wiping and drying rope 102 can be tensioned, the curved surface being cleaned can be attached by the wiping and drying rope 102, and the cleaning force is ensured. The deformation of the elastic element 110 changes along with the change of the curvature radius of the curved surface to which the wiping cord 102 is attached, so that the degree of the wiping cord 102 attached to the curved surface is adjusted, and the self-adaptive adjustment of the cleaning force is realized.
Referring to fig. 3, the adjustment assembly 104 may further include a link 112 and a connection seat 113 to facilitate connection of the elastic member 110 and the swing link 111 and transmission of force or moment.

Specifically, the two ends of the wiping cord 102 are respectively connected with an anti-tripping device 114, and are connected with the swing rod 111 of the adjusting component 104 through the anti-tripping device. The trip prevention 114 used for the end connection of the conventional steel cable can be adopted, and has the advantages of firm connection, trip prevention and convenient switching. The stability of the end connection of the wiping rope 102 can be guaranteed by the anti-tripping device 114, the anti-tripping device 114 can be connected to the swing rod 111 through a revolute pair, the end switching of the wiping rope 102 is realized, the friction loss of a connecting position is reduced, and compared with the scheme that the rope is directly connected with the swing rod 111, the difficulty of connection can be reduced, and the convenience of connection is improved.

Specifically, the wiping movement assembly 115 may employ an air cylinder or a linear module. The fixing frame 103 in the wiping bracket 101 may be connected to the sliding rail 116, and the sliding rail 116 extends along the second direction, thereby enabling support of the wiping mechanism 100 and limiting movement of the wiping mechanism 100 along the second direction. It should be noted that, for cleaning a wind power tower, the wiping mechanism 100 according to the embodiment of the present application may be used for wiping and cleaning a sprayed working surface, and as can be known from the above embodiment, the wiping mechanism 100 is applicable to a curved surface with a variable radius of curvature, and in the wiping process, the wiping rope 102 can be self-adaptively attached to the working surface, so as to ensure cleaning force. The cleaning device is applied to cleaning of wind power towers, can effectively remove water stains and residual stains, and improves cleaning efficiency.
