At this time, the first shell 101 and the second shell 102 are driven to rise along the tower by the driving component 105, thereby driving the moving seat 107, the bracket 103 and the camera 104 to rise. During the rising process, the air is transported to the blowing pipe 111 by the fan 110, and the air is blown out through the multiple nozzles on the blowing pipe 111, thereby blowing off the floating dust attached to the outer wall of the tower. When the tower needs to be inspected, the rotating component 112 is started to drive the moving seat 107 to move along the first shell 101 and the second shell 1 02 moves, thereby driving the bracket 103 and the camera 104 to move.

[0042] Second embodiment:

[0043] Based on the first embodiment, please refer to Figures 5 to 8 , Figure 5 is a schematic diagram of the installation structure of the drive motor of the second embodiment, Figure 6 2 is a schematic diagram of the installation structure of the driving gear of the second embodiment. Figure 7 is a schematic diagram of the installation structure of the third rack of the second embodiment, Figure 8It is a schematic diagram of the installation structure of the pressure sensor of the second embodiment. The driving assembly 105 of this embodiment includes a moving rod 201, an abutment wheel 202 and a moving member 203. The moving member 203 includes a third rack 205 and a driving gear 206. The moving rod 201 includes a rod body 209, a support 210 and a pressure sensor 211.

[0044] According to this specific embodiment, the moving rod 201 is slidably connected to the first shell 101 and passes through the first shell 101; the abutment wheel 202 is rotationally connected to the moving rod 201 and is located at one end of the moving rod 201; the moving component 203 is arranged on the first shell 101 and drives the moving rod 201 to move; a rotating motor 204 is also installed on the moving rod 201, and the output end of the rotating motor 204 is connected to the abutment wheel 202. Since the bottom diameter of the tower is large and the top diameter is small, the moving rod 201 is driven to move by the moving component 203, thereby driving the abutment wheel 202 to move, so that the abutment wheel 202 always abuts against the outer wall of the tower; the abutment wheel 202 is driven to rotate by the operation of the rotating motor 204, and then the abutment wheel 202 is lifted and lowered along the outer wall of the tower, thereby driving the first shell 101 and the second shell 102 to lift and lower, and achieving the purpose of driving the first shell 101 and the second shell 102 to lift and lower along the tower.

[0045] The driving gear 206 is rotatably connected to the first shell 101 and is located inside the first shell 101; the third rack 205 is fixedly connected to the moving rod 201, meshed with the driving gear 206, and located on one side of the moving rod 201; two of the third rack 205 and the driving gear 206 are respectively provided and are respectively located on both sides of the moving rod 201; the moving member 203 also includes two driving gears 207, the two driving gears 207 are meshed with each other and are respectively connected to the two driving gears 206; a driving motor 208 is also installed on the first shell 101, and the output end of the driving motor 208 is connected to the output end of the driving motor 208. The driving gears 207 are connected to one of the driving gears 207, and one of the driving gears 207 is driven to rotate by the driving motor 208, thereby driving the corresponding driving gear 206 to rotate. Since the two driving gears 207 are meshed, when one driving gear 207 rotates, it will drive the other driving gear 207 to rotate, thereby driving the other corresponding driving gear 206 to rotate, so that the two driving gears 206 rotate in opposite directions, thereby driving the two third racks 205 to move, so that the third racks 205 drive the moving rod 201 to move, thereby driving the abutment wheel 202 to move, so that the abutment wheel 202 always abuts against the tower surface.

[0046] Secondly, the rod body 209 is slidably connected to the first shell 101, and is fixedly connected to the third rack 205, and penetrates the first shell 101; the support 210 is slidably connected to the rod body 209, and is rotationally connected to the abutment wheel 202, and is located at one end of the rod body 209; the pressure sensor 211 is fixedly connected to the rod body 209, abuts against the support 210, and is located inside the rod body 209; the pressure sensor 211 is electrically connected to the multiple drive motors 208, and is electrically connected to the multiple drive motors 208. When the abutment wheel 202 abuts against the surface of the tower, the abutment wheel 202 drives the support 210 to move, and the support 210 applies force to the pressure sensor 211, monitors the pressure of the abutment wheel 202 on the tower surface in real time through the pressure sensor 211, and feeds back the pressure value to the drive motor 208. When the pressure value reaches the preset range, it indicates that the abutment wheel 202 is in good contact with the tower surface. When the pressure value exceeds the preset range, it indicates that the contact state between the abutment wheel 202 and the tower surface is abnormal. At this time, the drive motor 208 and the rotating motor 204 receive the signal from the pressure sensor 211 and automatically adjust the working state, such as ensuring that the first shell 101 and the second shell 102 are in a horizontal state, slowing down the lifting speed, suspending work, and other measures to ensure the stability of the device during operation.

4. The wind turbine tower inspection device according to claim 2, characterized in that: The telescopic rod includes a rotating sleeve, a spring and a connecting rod. The rotating sleeve is rotatably connected to the moving seat and is fixedly connected to the driven bevel gear and is located on one side of the driven bevel gear; the spring is connected to the rotating sleeve and is located inside the rotating sleeve; the connecting rod is slidably connected to the rotating sleeve, connected to the spring, and fixedly connected to the cleaning brush.

5. The wind turbine tower inspection device according to claim 1, characterized in that: The blowing pipe includes a first pipe body, a second pipe body and a connecting pipe, wherein the first pipe body is connected to the first shell, communicates with the output end of the blower, and is located inside the first shell; The second tube body is connected to the second shell and is located inside the second shell; both ends of the connecting tube are respectively connected to the first tube body and the second tube body, and the connecting tube communicates the first tube body and the second tube body.

6. The wind turbine tower inspection device according to claim 1, characterized in that: The driving assembly includes a moving rod, an abutment wheel and a moving component. The moving rod is slidably connected to the first shell and penetrates the first shell; the abutment wheel is rotationally connected to the moving rod and is located at one end of the moving rod. The moving component is arranged on the first shell and drives the moving rod to move.

7. A wind turbine tower inspection method, applied to the wind turbine tower inspection device as claimed in any one of claims 1 to 6, characterized in that: The following steps are involved: Placing the first shell and the second shell outside the tower, and connecting the first shell and the second shell by bolts; Starting the plurality of driving components to drive the first shell and the second shell to slowly rise along the outer wall of the tower until they reach a predetermined detection position; During the rising process of the first shell and the second shell, the fan is started to suck in air and transport it to the blowing pipe, and the nozzle on the blowing pipe blows out air to blow off the floating dust and impurities on the outer wall of the tower; When the first shell and the second shell reach a predetermined position, the rotating member is started to move the moving seat, the bracket and the camera along the outer wall of the tower; The moving seat drives the telescopic rod and the cleaning brush to move during the movement, so as to remove impurities and stubborn stains attached to the tower.
