DETAILED DESCRIPTION

[0021] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-4 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.

[0022] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] Embodiment 1, a wind turbine anti-climbing device, includes a main frame 1 and a control box 2, characterized in that:

[0024] The main frame 1 is slidably connected to a control box 2, the main frame 1 is provided with a telescopic rod 3 that cooperates with the control box 2, and the control box 2 is provided with a control handle 4 and two groups of control buttons 5;

[0025] The control box 2 is rotatably connected with a first guardrail 6 and a second guardrail 7, the first guardrail 6 is hingedly connected to the control box 2, and the second guardrail 7 is fixedly connected to the control box 2;

[0026] The first guardrail 6 is provided with two groups of sliding grooves 8, one group of the sliding grooves 8 is provided with a first electromagnet 9, and the other group of the sliding grooves 8 is provided with a second electromagnet 10, and the two groups of sliding grooves 8 are slidably provided with a positioning block 11, one end of the positioning block 11 is provided with an armature 12, and a return spring 13 is provided between the armature 12 and the electromagnet, and the second guardrail 7 is provided with a positioning hole 14 that cooperates with the positioning block 11;

[0027] One group of buttons cooperates with the first electromagnet 9, and the other group of buttons cooperates with the second electromagnet 10. Both the first electromagnet 9 and the second electromagnet 10 are electrically connected to the controller.

[0028] When in use, two groups of control buttons 5 are pressed at the same time. Through the controller, the first electromagnet 9 and the second electromagnet 10 are energized to generate magnetism, which attracts the armature 12 and disengages the positioning block 11 from the positioning hole 14. Since the first guardrail 6 is hinged to the control box 2, the first guardrail 6 can be moved to move, and the operator enters the main frame 1. After entering, the first guardrail 6 is reset, and the two groups of control buttons 5 are released. The electromagnet loses power. Under the action of the reset spring 13, the positioning block 11 cooperates with the positioning hole 14. Under the action of the first guardrail 6 and the second guardrail 7, the operator is restricted to a certain range of the main frame 1. The operator uses a safety lock to further fix the guardrail to ensure the safety of the operator.

[0029] According to the height of the operator, the telescopic rod 3 can be activated to adjust the height of the control box 2 until it is suitable for the height of the operator, which is easy to adjust;

[0030] Through the above working method, the utility model can unlock the first guardrail 6 and the second guardrail 7 by pressing two groups of control buttons 5, avoiding accidental touch resulting in separation of the first guardrail 6 and the second guardrail 7, thereby causing life danger to the operator.

[0031] Embodiment 2, on the basis of embodiment 1, a shock absorbing block 15 is provided at the bottom of the main frame 1, and a shock absorbing spring 16 is connected between the shock absorbing block 15 and the main frame 1; two groups of shock absorbing blocks 15 are provided at the bottom, and wear-resistant plates are provided at the bottom of the two groups of shock absorbing blocks 15; sponge pads are provided on the inner walls of the first guardrail 6 and the second guardrail 7; and an anti-slip foot pedal 17 is provided on the main frame 1.

[0032] When descending, the shock absorbing block 15 and the shock absorbing spring 16 can reduce the vibration force of the main frame 1 when it descends, thereby ensuring the stability of the equipment when it descends and further improving the safety of the equipment.

[0033] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
