[0020] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-3 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0021] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0022] Embodiment 1, a monitoring device applied to a wind turbine tower base, comprises a base 1 and a camera 2, and is characterized in that:

[0023] The base 1 is rotatably connected to a rotating seat 3, and the rotating seat 3 is driven by a first power device;

[0024] The rotating cylinder is provided with a telescopic rod 4, the extended end of the telescopic rod 4 is provided with a mounting plate 5, the mounting plate 5 is slidably connected with a sliding plate 6, and the sliding plate 6 is driven by a second power device;

[0025] The sliding plate 6 is provided with a sliding groove 7, in which a sliding block 8 is matched, and a camera 2 is provided on the bottom plate of the sliding block 8. The sliding plate 6 is threadedly connected with a locking screw 9 matched with the sliding block 8;

[0026] The first power device comprises a first motor 10 provided on the base 1, the rotating base 3 is driven by the first motor 10, and the first motor 10 is electrically connected to the controller;

[0027] The second power device includes a sliding groove 7 provided on the mounting plate 5, the sliding groove 7 is rotatably connected to a screw 11 threadedly connected to the sliding plate 6, a second motor 12 is provided on the mounting plate 5, the screw 11 is driven by the second motor 12, and the second motor 12 is electrically connected to the controller;

[0028] The sliding groove 7 and the sliding block 8 are provided by a dovetail groove and a dovetail block;

[0029] The base 1 is C-shaped, and a placement plate 13 that matches the first motor 10 is detachably connected to the bottom plate;

[0030] The telescopic rod 4 is an electric telescopic rod or a hydraulic telescopic rod.

[0031] When in use, by starting the first motor, the rotating seat can be driven to rotate along the circumferential direction to adjust the rotation angle of the camera. The length of the mounting plate determines the range of rotation detection;

[0032] When adjusting the height distance of the camera, the height adjustment of the camera is achieved by driving the telescopic rod;

[0033] By driving the second motor to drive the lead screw to rotate, the sliding plate moves along the sliding slot, thereby adjusting the camera monitoring position, facilitating adjustment, and increasing the monitoring range;
