[0020] Numerous specific details are described below to provide a thorough understanding of the present invention. It should be understood, however, that this invention may be implemented otherwise than by the embodiments described herein. One skilled in the art may make similar generalizations while maintaining the spirit of this invention. Therefore, this invention is not limited to the specific embodiments disclosed below.

[0021] Second, "one embodiment" or "an embodiment" refers herein to a particular feature, structure, or characteristic that may be included in at least one embodiment of the present invention. The phrase "in one embodiment" appears in various places throughout the specification does not necessarily refer to the same embodiment, nor does it refer to embodiments that are individually or alternatively mutually exclusive with other embodiments.

[0022] Furthermore, the present invention is described in detail with reference to schematic representations. In the detailed explanation of the embodiments of this invention, sectional views of component structures may be partially enlarged and not true to scale for better illustration. These schematic representations are merely examples and are not intended to limit the scope of this invention. Furthermore, three-dimensional dimensions such as length, width, and depth should be considered in actual production. Example 1

[0023] With reference to the Fig. 1 to 9, a first embodiment of the present invention is described, in which a tower cleaning device is provided which comprises a main body 100 comprising an annular frame 101 and a support frame 102, wherein the annular frame 101 is formed by connecting four arcuate frames by means of screws, wherein one of the support frames 102 is arranged on each of the arcuate frames 101, wherein a clamping wheel 103 is connected to the support frame 102.

[0024] It also includes a cleaning mechanism 200, wherein the cleaning mechanism 200 is arranged on the main body 100, and the cleaning mechanism 200 comprises a clamping and adjusting mechanism 201, a gear synchronization mechanism 202, a drive mechanism 203, a drive synchronization mechanism 204, a reciprocating brush mechanism 205, and a water spray mechanism 206, wherein the clamping and adjusting mechanism 201 is arranged on the annular frame 101, and the clamping and adjusting mechanism 201 is configured to adjust the support frame 102, wherein the gear synchronization mechanism 202 is arranged on the clamping and adjusting mechanism 201, and the four support frames 102 are synchronously adjusted by the gear synchronization mechanism 202, wherein the drive mechanism 203 is connected to the annular frame 101 and is configured to rotate the clamping wheel 103,wherein the drive synchronization mechanism 204 is connected to the drive mechanism 203, and the clamping wheels 103 on the four support frames 102 are driven synchronously by the drive synchronization mechanism 204, wherein the reciprocating brush mechanism 205 is arranged on the support frame 102 and is configured to perform reciprocating brushing, and wherein the water spray mechanism 206 is attached to the reciprocating brush mechanism and is configured to spray water in the reciprocating brushing.

[0025] Furthermore, the annular frame 101 includes four arcuate water tanks 101a, each formed as a quarter-circle ring. An upper annular plate 101b is secured above each of the arcuate water tanks 101a, a lower annular plate 101c is secured below each of the arcuate water tanks 101a, and a supporting arc plate 101d is secured to the outer arcuate surface of the arcuate water tank 101a. It is worth noting that by connecting the four arcuate water tanks 101a together, a complete annular structure is formed. This structure serves as a supporting base.

[0026] It should be noted that by activating the drive mechanism 203, the drive mechanism 203 causes the clamping wheels 103 to rotate, while at the same time, the drive synchronization mechanism 204 achieves synchronous rotation of the clamping wheels 103 on the four support frames 102, thereby enabling the device to climb. The tower has a conical shape. During the climbing process, the clamping and adjustment mechanism 201 is automatically adjusted according to the conical shape of the tower to ensure that the clamping wheels 103 continuously rest against the tower, thus enabling climbing.

[0027] The water spray mechanism 206 sprays water, while the reciprocating brush mechanism 205 continuously performs reciprocating brushing on the tower. This allows the tower to be completely cleaned simultaneously during the climbing process of the device. Example 2

[0028] With reference to the Fig. 1 to 16, this embodiment differs from the first embodiment in that the clamping and adjusting mechanism 201 comprises a spindle nut 201a, a spindle 201b and an adjusting motor 201c, wherein the spindle nut 201a is passed through a large through-hole 201d of the arc-shaped water tank 101a and is connected to the latter at the large through-hole 201d via a bearing, the spindle 201b is threadedly connected to the spindle nut 201a, one end of the spindle 201b is fastened to the support frame 102, and an active adjusting bevel gear 201e is fastened to the outside of the spindle nut 201a.The support arch plate 101d is connected via a bearing to a support shaft 201f, wherein a passive adjusting bevel gear 201h is attached to one end of the support shaft 201f, wherein the passive adjusting bevel gear 201h is toothed with the active adjusting bevel gear 201e, and wherein one of the support shafts 201f is fixedly connected to an output shaft of the adjusting motor 201c.

[0029] It should be noted that during clamping adjustment, the adjustment motor 201c is activated, causing the support shaft 201f to rotate. Because the passive adjustment bevel gear 201h meshes with the active adjustment bevel gear 201e, the spindle nut 201a is rotated, causing the spindle 201b to slide. The sliding of the spindle 201b adjusts the support frame 102.

[0030] In particular, the transmission synchronization mechanism 202 includes a transmission adjusting ring gear 202a, the transmission adjusting ring gear 202a being rotatably connected to the outer side of the annular frame 101. A transmission adjusting gear 202b is attached to each of the support shafts 201f, and the transmission adjusting gears 202b are meshed with the transmission adjusting ring gear 202a.

[0031] It should be noted that a gear adjustment gear 202b is attached to each support shaft 201f, with the gear adjustment gears 202b being meshed with the gear adjustment ring gear 202a. The gear adjustment ring gear 202a and the arcuate water tank 101a are rotatably connected as follows: The gear adjustment ring gear 202a consists of four gear rings formed as a quarter-circle ring. Each of the gear rings is provided on one side with a plurality of hemispherical recesses 202c, with balls 202d inserted into the hemispherical recesses 202c and secured by cover plates 202e. The cover plates 202e are provided with a round opening in the center, with the balls 202d projecting into an annular ball groove 202f on the outer annular surface of the arcuate water tank 101a. One end of the quarter-circle ring gear has a magnet block 202g, while at the other end an iron block 202h is arranged.

[0032] After the annular frame 101 is fully assembled, the four quarter-circle ring gears are assembled into a complete annular structure. At this time, the iron block 202h and the magnetic block 202g of the adjacent arcuate ring gears attract each other, while at the same time, each ball 202d protrudes into the annular ball groove 202f on the outer ring surface of the arcuate water tank 101a, thereby achieving a bearing-like connection effect.

[0033] One of the support shafts 201f is driven by the adjustment motor 201c. This rotates the gear adjustment gear 202b, thereby causing the gear adjustment ring gear 202a to rotate. The gear adjustment gears 202b on the three other support shafts 201f are rotated via the gear adjustment ring gear 202a, causing the three other support shafts 201f to rotate. This enables synchronous adjustment of the four clamping and adjustment mechanisms 201 and thus synchronous movement of the four support frames 102.

[0034] Since the movement speed of the variable speed motor 201c depends on the conical change of the turret, the turret's cone angle must be calculated in advance. The cone angle of both the active drive bevel gear 203i and the passive drive bevel gear 203g is 45° with a gear ratio of 1:1. For example, the angle between the inclined surface of the turret and the vertical surface is A, and the diameter of the wheel body 103b of the clamping wheel 103 is D. The travel distance for one revolution of the clamping wheel 103 is πD. For one revolution of the clamping wheel 103, the outer sleeve shaft 203a rotates once, while simultaneously the drive shaft 203h makes one revolution. At a speed of the variable speed motor 201c of BU / min, the time for one revolution is 1 / B minutes. During this time, the support frame 102 must make a length adjustment of L = πDtanA.With a pitch N of the spindle 201b, one revolution of the spindle nut 201a causes the support frame 102 to move by N. Thus, the required number of revolutions of the spindle nut 201a for the travel distance is LL / N revolutions. Since both the active adjusting bevel gear 201e and the passive adjusting bevel gear 201h have a cone angle of 45° with a gear ratio of 1:1, the support shaft 201f must make L / N revolutions. Consequently, the adjusting motor 201c must make L / N revolutions within 1 / B minutes, from which it determines the speed of the adjusting motor 201c as. LBN r / min. This arrangement ensures that the device always climbs under a clamping action during the climbing process. When the device is positioned at the bottom of the tower after assembly, only the clamping and adjusting mechanisms 201 are initially adjusted to move the support frames 102, whereby the clamping wheels 103 clamp the tower, with the compression spring 103c in the compressed state. After this adjustment is completed, the drive motor 203j, the adjusting motor 201c, the reciprocating motor 205e, and the four water supply pumps 206a are simultaneously activated to enable reciprocating brushing of the tower during the climbing process.

[0035] Furthermore, the drive mechanism 203 comprises an outer sleeve shaft 203a and an inner plug-in shaft 203b, wherein the inner plug-in shaft 203b is inserted into the outer sleeve shaft 203a and is slidably connected to the outer sleeve shaft 203a, the inner plug-in shaft 203b is provided with a slide strip 203k at each end, while the outer sleeve shaft 203a has sliding grooves on the inside which interact with the slide strips 203k, whereby the inner plug-in shaft 203b is slidably guided in the outer sleeve shaft 203a. The outer sleeve shaft 203a is passed through a small through hole 201j of the arcuate water tank 101a and is connected to the small through hole 201j via a bearing, whereby the inner plug shaft 203b is slidably guided in the outer sleeve shaft 203a during the movement of the support frame 102 without impairing the power transmission of the drive mechanism 203.The inner stub shaft 203b is passed through a mounting box 203d on a wheel carrier 203c and engages with a transmission drive bevel gear 203e, wherein the inner stub shaft 203b is connected to the mounting box 203d internally via a bearing, and a passive drive bevel gear 203g is attached to a wheel axle 203f of the clamping wheel 103, wherein the passive drive bevel gear 203g is toothed with the transmission drive bevel gear.

[0036] Furthermore, the clamping wheel 103 comprises a telescopic rod 103a, the wheel carrier 203c and a wheel body 103b, wherein a compression spring 103c is mounted on the telescopic rod 103a, one end of the telescopic rod 103a is fastened to the support frame 102, the other end is fastened to the wheel carrier 203c, and the wheel carrier 203c is connected to the wheel body 103b via the wheel axle 203f.

[0037] Still further, the upper ring plate 101b is connected via a bearing to a drive shaft 203h, wherein an active drive bevel gear 203i is fixed to one end of each of the drive shafts 203h, and the transmission drive bevel gear 203e is fixed to one end of the outer sleeve shaft 203a, wherein the active drive bevel gear 203i is meshed with the transmission drive bevel gear 203e, and wherein one of the drive shafts 203h is fixedly connected to the output shaft of the drive motor 203j.

[0038] It should be noted that by activating the drive motor 203j, the drive motor 203j rotates the drive shaft 203h, thereby rotating the active drive bevel gear 203i. Since the active drive bevel gear 203i meshes with the transfer drive bevel gear 203e, both the outer sleeve shaft 203a and the inner plug shaft 203b are rotated simultaneously. The transfer drive bevel gear 203e meshes with the passive drive bevel gear 203g on the wheel axle 203f, causing the wheel axle 203f to rotate and thus causing the clamping wheel 103 to rotate.

[0039] The remaining structure is the same as in Example 1. Example 3

[0040] With reference to the Fig. 10 to 16, this embodiment differs from the above embodiments in that the drive gear ring 204a and the gear adjustment gear ring 202a have the same structure, with both consisting of four gear rings formed as a quarter-circle ring. Each of the gear rings is provided on one side with a plurality of hemispherical recesses 202c, with balls 202d inserted into the hemispherical recesses 202c and secured by cover plates 202e, with the balls 202d projecting into an annular ball groove 202f on the outer annular surface of the arcuate water tank 101a. One end of the quarter-circle ring gear ring has a magnet block 202g, while the other end has an iron block 202h.

[0041] Specifically, the drive synchronization mechanism 204 includes a drive ring gear 204a, the drive gear 204b is rotatably connected to the annular frame 101, and the drive gear 204b is fixed to each of the drive shafts 203h, the drive gear 204b being meshed with the drive ring gear 204a.

[0042] It should be noted that after the sprockets are assembled into a complete sprocket, the drive gears 204b are meshed with the drive gear 204a. When the drive gear 204a is rotated by one drive gear, the other three drive gears 204b will also rotate. This achieves synchronous rotation of the clamping wheels 103 on each support frame 102, ensuring the drive action.

[0043] It should also be noted that during reciprocating brushing, the reciprocating motor 205e is activated. The reciprocating motor 205e drives the connecting plates 205f to rotate. Because the pins 205g are inserted into the elongated holes 205h on the corresponding sides, and the elongated holes 205h are arranged horizontally, this causes the π-shaped plate 205a to move up and down. The two ends of the π-shaped plate 205a each engage a slot 205i of the support frame 102, and limiting wheels 205j are attached to both sides of the slot 205i, which serve as stops and ensure smooth sliding of the π-shaped plate 205a. While the π-shaped plate 205a slides up and down, reciprocating, its bristles 2051 perform up and down, reciprocating brushing on the tower.

[0044] Since the reciprocating brush mechanisms 205 of the four support frames 102 move simultaneously during the reciprocating movement, to avoid movement interference, the left and right brush plates 205b are fixed to the lower portion of the π-shaped plate 205a, while the front and rear brush plates 205b are fixed to the upper portion of the π-shaped plate 205a. This staggered arrangement prevents collisions and interference during movement.

[0045] Furthermore, the water spray mechanism 206 comprises a water supply pump 206a, wherein each of the arc-shaped water tanks 101a corresponds to a water supply pump 206a, the outlet of the arc-shaped water tank 101a is connected to an inlet of the water supply pump 206a, the outlet of the water supply pump 206a is connected to a water supply pipe 206c via a connecting hose 206b, the water supply pipe 206c being fixed to the brush plate 205b by means of a semicircular clamp 206d, and a plurality of water spray nozzles 206e are fixed to the water supply pipe 206c.

[0046] It should be noted that the water supply line 206c is also a hose, so that the water supply line 206c can also bend as the curvature of the brush plate 205b changes without affecting the water supply. By activating the water supply pump 206a, water is sucked from the arcuate water tank 101a and supplied to the water supply line 206c via the connecting hose 206b. Each water spray nozzle 206e on the water supply line 206c passes through an enlarged hole at a corresponding position of the brush plate 205b, and the water is sprayed through the water spray nozzles 206e. During spraying, the reciprocating brush mechanism 205 performs reciprocating brushing, thereby achieving cleaning of the tower.

[0047] The remaining structure is the same as in Example 2.

[0048] Procedure: Before cleaning, the tower cleaning device should be mounted at the base of the tower. The operator first places the device's annular frame 101 around the tower. The annular frame 101 is formed by connecting four arcuate frames with screws. Attached to each arcuate frame are the upper annular plate 101b and the lower annular plate 101c, as well as the support arc plate 101d, which provides a stable support platform for the device. The clamping and adjustment mechanism 201 is then activated. The adjustment motor 201c drives the rotation of the support shaft 201f, which rotates the spindle nut 201a via the meshing of the bevel gears. The threaded connection between the spindle nut 201a and the spindle 201b causes the spindle 201b to slide, ultimately adjusting the support frame 102. This allows the clamping wheel 103 to fit tightly against the surface of the tower.The compression spring 103c of the clamping wheel 103 is pre-tensioned, which ensures the stability and adhesion of the device during climbing.

[0049] After confirming that the clamping wheels 103 have securely clamped the tower, the operator must check the device's water supply system to ensure that the water supply pumps 206a and the water spray mechanisms 206a have been charged with sufficient clean water. The operator then simultaneously activates the drive motor 203j, the variable displacement motor 201c, the reciprocating motor 205e, and the water supply pumps 206a. The drive motor 203j drives the drive shaft 203h to rotate. Because the active drive bevel gear 203i at the end of the drive shaft 203h meshes with the transmission drive bevel gear 203e on the outer sleeve shaft 203a, the outer sleeve shaft 203a and the inner plug shaft 203b rotate together. This rotates the clamping wheel 103, which drives the device to climb up along the tower.At the same time, the support frame 102 is automatically adjusted by the adjustment motor 201c according to the conical change of the tower to ensure that the device always rests against the surface of the tower during the climbing process, thereby avoiding skewing due to the change in the diameter of the tower.

[0050] As the device climbs, the reciprocating motor 205e drives the π-shaped plate 205a to reciprocate, which drives the brush plate 205b to brush the surface of the tower. The π-shaped plate 205a is slidably connected to the support frame 102 and connected to the brush plate 205b via the mounting block 205c. The reciprocating motor 205e mounted on the seat plate 205d is a double-shaft drive motor 203j, whose output shafts on both sides are respectively connected to the π-shaped plate 205a via the connecting plate 205f and the pin 205g, thus realizing the linear reciprocating motion of the π-shaped plate 205a.Under the action of the water spray mechanism 206, the water supply pump 206a sucks clean water from the arc-shaped water tank 101a, delivers it to the water supply pipe 206c via the connecting hose 206b, and then the water is evenly sprayed onto the tower surface through the water spray nozzles 206e. Combined with the reciprocating brushing, the dirt on the tower is effectively removed. It is worth noting that the reciprocating motor 205e in the present invention can be a dual-shaft drive motor, or two servo motors can be used, each connected to the π-shaped plate 205a via the connecting plate 205f and the plug pin 205g to realize the linear reciprocating motion of the π-shaped plate 205a. The advantage of the dual-shaft drive motor is that both shafts can be driven simultaneously, with synchronous rotation speeds, which increases production efficiency.The advantage of servo motors is their low maintenance costs and long service life. Since both double-headed motors and servo motors are state-of-the-art, they will not be discussed further here. Users can select the motor according to their application. See the . Fig. 10 and Fig. 11 shows a double-shaft drive motor for illustration purposes.

[0051] When the device reaches the top of the tower, the operator must sequentially stop the drive motor 203j, the variable pitch motor 201c, the reciprocating motor 205e, and the water supply pumps 206a to prevent accidents caused by excessive climbing. After cleaning, the operator should carefully check the wear of each component of the device and replace or repair them if necessary to ensure the safety and efficiency of the next use. The entire cleaning process is automated, which greatly improves cleaning efficiency and also eliminates the safety risks of manual work at height, making it ideal for the regular cleaning and maintenance of wind turbine towers.
