[0017] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Please refer to Figures 1 to 8 As shown, a high-protection seamless sliding contact line for wind towers according to the present invention includes a movable frame, a flexible current collection mechanism, a seamless sliding contact line 12, a mounting frame 6, and a protective component. One side of the movable frame is connected to the upper part of the flexible current collection mechanism, and the lower part of the flexible current collection mechanism is slidably connected to the upper part of the seamless sliding contact line 12. The mounting frame 6 is installed on the lower part of the seamless sliding contact line 12, and the protective component is detachably connected to the mounting frame 6. The flexible current collection mechanism includes a slide table 5, a flexible connecting component, a guiding component, a flexible sliding contact component, and a power receiving component 17. The slide table 5 has a first sliding groove in its middle. The lower part of the flexible connecting component is slidably connected to the first sliding groove. The movable frame is connected to the upper part of the flexible connecting component. The slide table 5 has several power receiving grooves. One flexible sliding contact component is disposed in each power receiving groove. All flexible sliding contact components are connected to the power receiving component 17. The guiding components are disposed on both sides of the slide table 5. The slide table 5 is slidably connected to the upper part of the seamless sliding contact line 12 through the guiding components. The flexible sliding contact component is slidably connected to the upper part of the seamless sliding contact line 12.

[0019] The working principle of this invention is as follows: During the actual installation of the wind tower, the seamless sliding contact line 12 can be installed on the inner wall of the wind tower through the mounting frame 6. Then, the power supply line of the elevator is connected to the power receiving component 17, 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 12 through the moving frame. At the same time, the protective component protects the elastic current collection mechanism and the seamless sliding contact line 12. When the sliding contact power is collected, the elastic connecting component presses the sliding table 5 towards the seamless sliding contact line 12, so that the elastic sliding contact component can better contact the seamless sliding contact line 12. At the same time, the guiding component guides the sliding table 5 to prevent the sliding table 5 from deviating. Meanwhile, the elastic sliding contact component supplies power to the power supply line of the elevator through the power receiving component 17.

[0020] Furthermore, the elastic connection assembly includes a sliding block 9, a return spring 20, and a limiting component 15. The upper part of the sliding block 9 is provided with a mounting hole 16, and the movable frame is connected to the mounting hole 16. The return spring 20 is disposed at the bottom of the first slide groove, and the lower part of the sliding block 9 is slidably connected to the first slide groove. The lower part of the sliding block 9 abuts against the outside of the return spring 20. The limiting component 15 is disposed on the first slide groove, and the limiting component 15 is used to limit the movement range of the sliding block 9.

[0021] As can be seen from the above description, the upper part of the sliding block 9 is slidably connected to the moving frame through the mounting hole 16, which facilitates the sliding adjustment of the sliding block 9 on the moving frame. At the same time, the lower part of the sliding block 9 is connected to the first slide groove through the return spring 20. When the seamless sliding contact line 12 fluctuates, the seamless sliding contact line 12 squeezes the return spring 20 through the elastic sliding contact component and the slide table 5. At the same time, the return spring 20 collapses to adapt to the fluctuations and the fluctuation range is limited by the limiting component 15.

[0022] Furthermore, the guiding assembly includes a rotating seat 13, a rotating shaft 14, and a guide wheel 4. The rotating seat 13 is connected to the slide table 5, the guide wheel 4 is rotatably connected to the rotating seat 13 via the rotating shaft 14, and the guide wheel 4 is slidably connected to the seamless sliding contact line 12.

[0023] As can be seen from the above description, the slide table 5 is slidably connected to the seamless sliding contact line 12 via the guide wheel 4, which helps to prevent the slide table 5 from deviating.

[0024] Furthermore, the elastic sliding contact assembly includes a carbon brush 18 and a torsion spring 11. The lower surface of the carbon brush 18 is slidably connected to the contact groove. One side of the torsion spring 11 is connected to the slide table 5 via a pin, and the other side of the torsion spring 11 is pressed against the upper surface of the carbon brush 18. The upper part of the carbon brush 18 is connected to the contact assembly 17 via a contact post 10.

[0025] As can be seen from the above description, it is beneficial for the carbon brush 18 to always maintain contact with the seamless sliding contact line 12 under the action of the torsion spring 11, and to draw power through the carbon brush 18.

[0026] 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, and 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 passes through the mounting hole 16.

[0027] 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 sliding block 9 through the connecting part 2, and slides in the mounting hole 16 through the connecting part 2, so that the sliding block 9 can adapt to the lateral offset of the seamless sliding contact line 12.

[0028] Furthermore, the mounting bracket 6 is detachably connected to the lower part of the seamless sliding contact line 12 by bolts.

[0029] As can be seen from the above description, it is beneficial for the seamless sliding contact line 12 to be better installed on the mounting bracket 6.

[0030] Furthermore, the protective assembly includes a left protective plate 7 and a right upper protective plate 3. The lower part of both the left protective plate 7 and the right upper protective plate 3 is provided with a slot. The two sides of the mounting bracket 6 are provided with a locking block that matches the slot. One side of the mounting bracket 6 is detachably connected to the slot at the lower part of the left protective plate 7 through the locking block, and the other side of the mounting bracket 6 is detachably connected to the slot at the lower part of the right upper protective plate 3 through the locking block.

[0031] As can be seen from the above description, it is beneficial to better protect the seamless sliding contact line 12 and the flexible current collection mechanism through the left protective plate 7 and the upper right protective plate 3.

[0032] Furthermore, a passage gap is provided between the upper part of the left protective plate 7 and the upper part of the right upper protective plate 3, and the connecting part 2 passes through the passage gap.

[0033] As can be seen from the above description, it is beneficial for the connecting part 2 to move flexibly through the gap.

[0034] Furthermore, a flexible baffle 8 is provided on the upper part of the left protective plate 7 and the upper part of the right upper protective plate 3.

[0035] As can be seen from the above description, the flexible baffle 8 helps to prevent dust from entering the left protective plate 7 and the upper right protective plate 3 through the gap.

[0036] Furthermore, the left protective plate 7, the upper right protective plate 3, the mounting bracket 6, and the two flexible baffles 8 together form a protective frame, and the seamless sliding contact line 12 and the elastic current collection mechanism are disposed inside the protective frame.

[0037] As can be seen from the above description, this arrangement is beneficial for better protection of the seamless sliding contact line 12 and the flexible current collection mechanism within the protective frame. Example 1
