DETAILED DESCRIPTION

[0027] Example, by Figure 1-7 The utility model includes an annular plate 1, a plurality of stabilizing mechanisms 3 are connected through the outer side of the annular plate 1, an annular slide rail 4 is fixedly connected to the bottom of the inner side of the annular plate 1, a mounting plate 5 is installed on the front side of the bottom of the annular plate 1, and a rotating mechanism 6, a distance adjustment mechanism 7, a brushing mechanism 8 and a flushing mechanism 9 are installed on the mounting plate 5;

[0028] The brushing mechanism 8 includes a shaft 81, which is movably connected to the front side of the bottom of the mounting plate 5 through a bearing. A cleaning brush 82 is fixedly connected to the outer end of the shaft 81, and a second motor 83 is fixedly connected to the rear side of the top of the mounting plate 5. The output shaft of the second motor 83 and the outer end of the shaft 81 are respectively fixedly connected to a gear 84, and the two gears 84 are engaged with each other.

[0029] The rotating mechanism 6 is located in the front side of the brushing mechanism 8, and the rotating mechanism 6 includes a connecting sleeve 61, which is sleeved on the outer end of the mounting plate 5, and the connecting sleeve 61 and the mounting plate 5 are slidably connected. The top of the connecting sleeve 61 is fixedly connected with a sliding sleeve 62 and a first motor 63, and the sliding sleeve 62 is sleeved on the annular slide rail 4. The first motor 63 is located in the front side of the annular plate 1, and the output shaft of the first motor 63 is fixedly connected with a friction wheel 64. The outer end of the friction wheel 64 contacts the front side of the annular plate 1. The sliding sleeve 62 in the rotating mechanism is sleeved on the annular slide rail 4, and then cooperates with the first motor 63 and the friction wheel 64 to drive the mounting plate 5 to rotate around the wind turbine tower, thereby enabling the brushing mechanism 8 to rotate around the wind turbine tower and brush.

[0030] The distance adjusting mechanism 7 includes an electric push rod 71, which is located above the mounting plate 5. The front and rear ends of the electric push rod 71 are respectively fixedly connected to a second connecting plate 73 and a first connecting plate 72. The second connecting plate 73 is fixedly connected to the front side of the top of the mounting plate 5, and the first connecting plate 72 is fixedly connected to the front side of the top of the connecting sleeve 61. Since the wind turbine tower has different thicknesses at the top and bottom, the bottom is thicker and the more it is washed, the more it moves downward on the wind turbine tower for cleaning. Therefore, the mounting plate 5 and the brushing mechanism 8 can be gradually adjusted to adapt to the movement of the outer wall of the wind turbine tower through the distance adjusting mechanism 7, so that the brushing mechanism 8 is always in a better cleaning space with the outer wall of the wind turbine tower.

[0031] The flushing mechanism 9 includes two nozzles 91, which are respectively located on both sides of the shaft 81. The outer end of the nozzle 91 is fixedly sleeved with a fixing seat 92, and the fixing seat 92 is fixedly connected to the rear side of the bottom of the mounting plate 5. The front side of the nozzle 91 is fixedly connected to a water pipe 93. The flushing mechanism 9 can spray water for humidification and flushing when the brushing mechanism 8 brushes the outer wall of the wind turbine tower. The two work together to achieve a better cleaning effect.

[0032] The stabilizing mechanism 3 includes a cylinder 31, which passes through the annular plate 1, and the annular plate 1 and the cylinder 31 are fixedly connected. The output shaft of the cylinder 31 is fixedly connected to a hard plate 32, and a rubber pad 33 is fixedly connected to the hard plate 32. Whenever the annular plate 1 descends to a certain height on the wind turbine tower and pauses, the stabilizing mechanism 3 can support the outer wall of the wind turbine tower to help the annular plate 1 stabilize and avoid shaking of the annular plate 1 due to wind.

[0033] The annular plate 1 is composed of a first half-ring plate 11 and a second half-ring plate 12, and the annular slide rail 4 is composed of a first half-ring slide rail 41 and a second half-ring slide rail 42. The first half-ring slide rail 41 and the second half-ring slide rail 42 are respectively fixedly connected to the inner bottom of the first half-ring plate 11 and the second half-ring plate 12. Two protrusions 111 are fixedly connected to the rear side of the first half-ring plate 11, and two grooves 121 are provided on the front side of the second half-ring plate 12. The protrusions 111 are adapted to be located inside the grooves 121. The annular plate 1 can be disassembled into the first half-ring plate 11 and the second half-ring plate 12, which is convenient for disassembly and assembly. The protrusions 111 and the grooves 121 can assist in the assembly of the first half-ring plate 11 and the second half-ring plate 12, so that the connection between them can be more stable.

[0034] A plurality of fastening mechanisms 2 are installed between the first semi-ring plate 11 and the second semi-ring plate 12, and the fastening mechanism 2 consists of a first connecting rod 21, a second connecting rod 22 and an internal threaded sleeve 23. The first connecting rod 21 and the second connecting rod 22 are fixedly connected to the inner side walls of the first semi-ring plate 11 and the second semi-ring plate 12 respectively. The internal threaded sleeve 23 is sleeved on one end of the first connecting rod 21 and the second connecting rod 22 close to each other, and the internal threaded sleeve 23 is threadedly connected to the first connecting rod 21 and the second connecting rod 22 respectively. The first semi-ring plate 11 and the second semi-ring plate 12 are assembled and fixed by a plurality of fastening mechanisms 2. There are four fastening mechanisms 2 in total, two of which are installed on each side of the annular plate 1, and the fastening mechanisms 2 on the same side are distributed up and down, so that the assembly of the first semi-ring plate 11 and the second semi-ring plate 12 is more stable and firm.

[0035] A plurality of traction ropes 10 are installed on the top of the annular plate 1. The traction ropes 10 consist of a rope body 101 and a hanging ring 102. The hanging ring 102 is fixedly connected to the rope body 101, and the rope body 101 is fixedly connected to the top of the annular plate 1. The traction ropes 10 can be used to suspend the annular plate 1 for high-altitude operations, and a winch can be installed on the top of the wind turbine tower. The winch cooperates with the traction ropes 10 to pull the annular plate 1 and control its up and down movement. The winch is a prior art, so it will not be described in detail here.

[0036] Working principle:

[0037] When in use, the first half ring plate 11 and the second half ring plate 12 are assembled together through the fastening mechanism 2 to form an annular plate 1, and the annular plate 1 is sleeved on the tower. The hanging ring 102 in the traction rope 10 is connected to the hoist at the top of the tower to pull the annular plate 1 so that it is sleeved on the tower and moved. The annular plate 1 is gradually lowered from a high position on the tower. When the annular plate 1 is lowered to a certain height, it is paused. Then, the cylinder 31 in the stabilizing mechanism 3 is immediately used to push the hard plate 32 close to the sleeve until the rubber pad 33 is against the outer wall of the tower. Multiple stabilizing mechanisms 3 cooperate to fix the annular plate 1 on the tower.

[0038] During cleaning, the distance adjustment mechanism 7 pushes the mounting plate 5 away from or close to the tower wall, and then drives the brushing mechanism 8 and the flushing mechanism 9 away from or close to the tower wall. When the position adjustment of the mounting plate 5 is completed, the second motor 83 is started. The second motor 83 drives the shaft 81 to rotate through the meshing transmission of the two gears 84. When the shaft 81 rotates, it drives the cleaning brush 82 to rotate and brushes the outer wall of the tower through the cleaning brush 82. During this period, the flushing mechanism 9 sprays water to the place on the tower that is cleaned by the cleaning brush 82. The brushing mechanism 8 and the flushing mechanism 9 cooperate to complete the tower cleaning. During the cleaning operation, the rotating mechanism 6 can drive the mounting plate 5 and the distance adjustment mechanism 7, the brushing mechanism 8 and the flushing mechanism 9 on the mounting plate 5 to circle around the tower along the annular slide 4 on the inner side of the annular plate 1. Specifically, the first motor 63 drives the friction wheel 64 to rotate the friction wheel 64 to rub the outer wall of the annular plate 1, and then cooperates with the sliding sleeve 62 in the rotating mechanism 6 to slide on the annular slide 4, thereby realizing the operation of circling around the tower along the annular slide 4. The brushing mechanism 8 rotates around the tower while cooperating with the flushing mechanism 9 to perform the cleaning operation;

[0039] After cleaning once at this height, the restriction of the stabilizing mechanism 3 on the tower is released so that the annular plate 1 can be lowered to a certain height through the cooperation of the traction rope 10 and the winch, and then the operation can be repeated.
