A touch switch 7 is fixedly installed at one end of the support frame plate 6 located in the sleeve frame 5. The trigger button of the touch switch 7 is in a state of being detached from the protective tube 4. The protective tube 4 is provided with a control circuit cabinet connected to the touch switch 7. The inner wall of the protective tube 4 is fixedly connected with a liquid storage cylinder 9 on one side of the four supporting structures. The liquid storage cylinder 9 corresponds to a side of the protective tube 4 in a hollow state. A telescopic device 11 connected to the control circuit cabinet is fixedly installed on the inner wall of the top surface of the liquid storage cylinder 9. The telescopic device 11 adopts a telescopic motor. The transmission shaft of the telescopic device 11 is fixedly connected with a piston 10 inserted into the inner wall of the liquid storage cylinder 9. The interior of the liquid storage cylinder 9 is filled with hydraulic oil below the piston 10. The liquid storage cylinder 9 is connected to the elastic pad 8 at the corresponding position through a pipeline.

[0023] The bottom ring 3 is nested with the outer wall of the tower body 1, an annular groove is cut on the inner edge of the bottom surface of the top ring 2, a sliding hole 17 is opened on the front of the top ring 2, an annular protrusion is provided on the inner edge of the top surface of the protective tube 4 and is nested with the top ring 2, and a toggle plate 12 is fixedly connected to the annular protrusion and is nested with the sliding hole 17, and the side of the toggle plate 12 is connected to the sliding hole 17 through a spring.

[0024] An electromagnet 13 is fixedly mounted on the front of the top ring 2 . The electromagnet 13 is connected to a control circuit cabinet on the protective tube 4 . When the electromagnet 13 is energized to generate magnetic force, it attracts the toggle plate 12 .

[0025] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5On the basis of the first embodiment, the difference between the second embodiment and the first embodiment is that the supporting structure is composed of a supporting frame plate 14 and an elastic pad 15, and the number of the supporting frame plate 14 and the elastic pad 15 are both multiple. The supporting frame plate 14 is a trapezoidal body with a hollowed-out side corresponding to the protective tube 4. Several supporting frame plates 14 are arranged from top to bottom and inserted into the sleeve frame 5. One end of the supporting frame plate 14 located in the sleeve frame 5 is connected to the outer wall of the protective tube 4 through a spring, and the spring is in a semi-compressed state. Several elastic pads 15 are respectively connected to the hollowed-out surfaces of several supporting frame plates 14, and several elastic pads 15 are connected to each other through pipes. The liquid storage cylinder 9 is connected to the lowest supporting frame plate 14 through a pipe, and one end of several supporting frame plates 14 located in the sleeve frame 5 is fixedly installed with a touch switch 7.

[0026] A touch switch 16 is fixedly installed at one end of the support frame plate 14 located inside the sleeve frame 5. The trigger button of the touch switch 1 7 is in a state of being separated from the protective tube 4, and the trigger button of the touch switch 16 is in a state of being in contact with the protective tube 4.

[0027] During use, when the outer wall of the tower body 1 is deformed and bulged, the outer wall on one side of the bulge applies pressure to the support frame plate 6, and the support frame plate 6 shrinks into the sleeve frame 5 and squeezes the button of the touch switch 7. The touch switch 7 triggers the transmission shaft of the telescopic device 11 on the corresponding side to descend and inject the hydraulic oil in the liquid storage cylinder 9 into the elastic pad 8. The elastic pad 8 expands when the hydraulic oil is injected and uses the hydraulic pressure to push the support frame plate 6 to fit tightly with the outer wall of the tower body 1, and then uses the support frame plate 6 to squeeze the outer wall of the tower body 1 to avoid more serious deformation of the tower body 1, thereby ensuring the normal operation of the wind turbine and preventing more serious deformation.

[0028] The distribution position of the supporting structure can be adjusted by toggling the toggle plate 12, and by energizing and de-energizing the electromagnet 13, the protective tube 4 is driven to reciprocate by magnetic attraction and the rebound of the spring on the toggle plate 12, thereby continuously adjusting the positions of the four supporting structures to achieve the effect of cyclic detection of the outer wall of the tower body 1. When the raised position is detected, the position is maintained by the friction force generated by the close fit between the support frame plate 6 and the outer wall of the tower body 1.

[0029] Through the vertical arrangement of several supporting frame plates 14, when the outer wall of the tower body 1 appears to be concave, the two ends of the protective tube 4 at the corresponding position extend from the sleeve frame 5 through the rebound of the spring and trigger the touch switch 16. The touch switch 16 starts the telescopic device 11 on the corresponding side and injects hydraulic oil into the elastic pad 15. The supporting frame plate 14 is tightly fitted with the outer wall of the tower body 1 under the hydraulic pressure of the elastic pad 15, thereby achieving a supporting effect.
