[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and examples.

[0020] Example 1

[0021] like Figure 1-Figure 4 A wind turbine tower deformation monitoring system shown includes a magnetic support body 1, a bracket 2, a through hole 3, a connecting rod 4, a counterweight 5, a magnetic seat 6, a camera device 7 and a target mark 8.

[0022] The magnetic support body 1 is in a concave hemispherical or bowl-shaped shape, the magnetic seat 6 is in the magnetic support body 1 and is in a state of repulsion with the magnetic support body 1, so that it is suspended in the magnetic support body 1, the magnetic support body 1 has a through hole 3, the bottom of the magnetic seat 6 is connected to a connecting rod 4 passing through the through hole 3, the connecting rod 4 is connected to a counterweight 5, and the counterweight 5 is a suspended ball or a suspended cone. A camera device 7, such as a camera or a camera, is installed on the top of the magnetic seat 6. A position mark, such as a crosshair 9, is set at the lens of the camera device 7, and a target mark 8 is set in the direction opposite to the lens of the camera device 7.

[0023] For new wind turbines, the verticality of each tower section is defined as 90 degrees. In this way, the device is installed on the ground of each floor of the wind turbine tower, and the camera device 7 takes photos. The photos contain the initial position of the position mark on the target mark 8. Then the camera device 7 takes photos regularly. When the position of the position mark on the target mark 8 moves, it means that the wind turbine tower is tilted. The tilt angle of the wind turbine tower can be calculated according to the trigonometric function based on the moving distance and the distance between the camera device 7 and the target mark 8. The direction of the wind turbine tower tilt is the opposite of the moving direction of the target mark 8. The camera device 7 is connected to a smart storage device, such as a mobile phone or a computer, so that the tilt condition of the wind turbine tower can be obtained remotely.

[0024] In this embodiment, Figure 1 As shown, the lens of the camera device 7 is arranged vertically upward, but it can be understood by those skilled in the art that it can be arranged toward the left side or the right side, etc., so as to detect the inclination of the wind turbine tower.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
