Description

Technical Field

[0001] This utility model relates to the field of sliding contact power generation technology, and in particular to an anti-detachment sliding contact power generation mechanism. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current. A wind turbine typically consists of components such as a rotor, generator, directional control unit (tail fin), tower, speed limiting safety mechanism, and energy storage device.

[0003] Wind towers typically have elevators installed inside, and these elevators are usually powered by sliding contact lines due to their height. However, traditional wind tower sliding contact lines have seams, and the unevenness of the seams and the fact that the inner surface of the wind tower is not completely flat cause the current collector to be easily vibrated when it moves, causing the current collector to temporarily separate from the sliding contact line, resulting in unstable power transmission.

The upper part of the following limit rod 13 is fixedly connected to the lower part of the slide table 5, and the lower part of the following limit rod is slidably connected to the limit groove 10.

[0016] The working principle of this utility model is as follows: During the actual installation of the wind tower, the seamless sliding contact line 6 can be installed on the inner wall of the wind tower through the mounting frame 11. Then, the power supply line of the elevator is connected to the power receiving component 4, and the other side of the moving frame is installed on the outside of the elevator. When the elevator moves, the elevator drives the elastic current collection mechanism to slide and collect power on the seamless sliding contact line 6 through the moving frame. When the sliding contact power is collected, the elastic sliding contact component is in close contact with the seamless sliding contact line 6 through its own elasticity. At the same time, the slide table 5 always follows the seamless sliding contact line 6 through the following limit rod 13, and the slide table 5 is prevented from deviating under the action of the guiding component.

[0017] Furthermore, a limiting slider is provided at the lower part of the limiting rod, and the limiting slider is slidably connected to the limiting groove 10. The limiting slider and the limiting groove 10 together limit the distance between the slide table 5 and the seamless sliding contact line 6.

[0018] As can be seen from the above description, it is beneficial to prevent the lower part of the limiting rod from disengaging from the limiting groove 10 by using the limiting slider.

The rotating seat 8 is connected to the slide table 5, the guide wheel 9 is rotatably connected to the rotating seat 8 via the rotating shaft 7, and the guide wheel 9 is slidably connected to the seamless sliding contact line 6.

[0020] As can be seen from the above description, the slide table 5 is slidably connected to the seamless sliding contact line 6 via the guide wheel 9, thus preventing the slide table 5 from deviating.

[0021] Furthermore, the elastic sliding contact assembly includes a carbon brush 14 and a torsion spring 12. The lower surface of the carbon brush 14 is slidably connected to the contact groove 15. One side of the torsion spring 12 is connected to the slide table 5 via a pin, and the other side of the torsion spring 12 is pressed against the upper surface of the carbon brush 14. The upper part of the carbon brush 14 is connected to the contact assembly 4 via a contact post 17.

[0022] As can be seen from the above description, it is beneficial for the carbon brush 14 to always maintain contact with the seamless sliding contact line 6 under the action of the torsion spring 12, and to draw power through the carbon brush 14.

[0023] Furthermore, the movable frame includes a mounting part 1 and a connecting part 2. One side of the connecting part 2 is provided with an external thread. One side of the connecting part 2 is detachably connected to the mounting part 1 by a nut. The other side of the connecting part 2 is slidably connected to the connecting lug 3.

[0024] As can be seen from the above description, it is advantageous for the mounting part 1 to be installed on the outside of the elevator. At the same time, the mounting part 1 is connected to the connecting lug 3 through the connecting part 2, and the connecting part 2 is slidably connected to the connecting lug 3, so that the connecting lug 3 can adapt to the lateral offset of the seamless sliding contact line 6.

[0025] Furthermore, the mounting bracket 11 is detachably connected to the lower part of the seamless sliding contact line 6 by bolts.

[0026] As can be seen from the above description, it is beneficial for the seamless sliding contact line 6 to be better installed on the mounting bracket 11.

[0027] Furthermore, a limiting half-groove 16 is provided on the outer side of the carbon brush 14, and an anti-detachment block is provided in the electrical connection groove 15. The anti-detachment block is slidably connected to the limiting half-groove 16, and the limiting half-groove 16 and the anti-detachment block together restrict the carbon brush 14 from detaching from the electrical connection groove 15.

[0028] As can be seen from the above description, this helps to prevent the carbon brush 14 from detaching from the contact slot 15. Example 1
