While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0047] like Figures 1 to 13 As shown, an embodiment of this utility model proposes a weeding device for an ultra-high voltage converter station, comprising:

[0048] The main frame 1 has a knife groove 11 at one end and an insulating rod connected to the other end.

[0049] The sickle 2 is disposed at one end of the main frame 1 and located on one side of the blade groove 11;

[0050] The cutting blade 3 is located at one end of the main frame 1 and on the other side of the blade groove 11. One end of the cutting blade 3 is rotatably connected to the main frame 1, and the other end is connected to the end of the insulating rod through a movable component.

[0051] In this embodiment, during use, the main frame 1 is extended to the weeds to be cut via an insulating rod. The retractable insulating rod then drives the sickle 2 on the main frame 1 to cut the weeds. When encountering grasses or trees with thicker roots (greater than a certain preset value), the roots are placed in the blade groove 11. Pulling the movable component at the end of the insulating rod rotates the cutting blade 3, causing it to be cut by the pressure of the blade and the groove 11. This weeding device for UHV converter stations solves the problem of incomplete protection during weeding by workers in fenced areas. It enables rapid clearing of grasses and trees within the UHV converter station area, improves the safety of personnel during weeding, ensures the safe and stable operation of the power grid, significantly shortens operation time, increases safety, and saves labor.

[0052] In an optional embodiment of this invention, the active component includes:

[0053] A movable arm 4 is positioned on one side of the cutting blade 3 and is rotatably connected to one end of the main frame 1;

[0054] One end of the movable arm 4 is connected to the end of the insulating rod via a pulling assembly.

[0055] In this embodiment, when in use, the movable arm 4 is pulled by the pulling component to rotate, thereby driving the cutting blade 3 to rotate, thus achieving the cutting of grass and tree roots and stems.

[0056] In an optional embodiment of this invention, the active component further includes:

[0057] Spring 5, one end of which is fixedly connected to one end of the main frame 1, and the other end of which is fixedly connected to one end of the movable arm 4.

[0058] In this embodiment, the spring 5 is used to rotate the movable arm 4 by rebounding after the cutting blade 3 cuts the rootstock, thereby driving the cutting blade 3 to reset.

[0059] In an optional embodiment of this utility model, the pulling component includes:

[0060] A first pulley assembly 61 is disposed at one end of the movable arm 4;

[0061] A second pulley 62 is provided at the other end of the main frame 1;

[0062] An insulating rope 63, one end of which is connected to the first pulley assembly 61, and the other end passes through the second pulley 62 and the first pulley assembly 61 in sequence and is connected to the end of the insulating rod.

[0070] One side of the sleeve 7 is clamped on the other end of the main frame 1 and is fixedly connected to the main frame 1 by a first screw. The other side of the sleeve 7 is sleeved on the insulating rod and is fixed to the insulating rod by a second screw passing through the first through hole 71 on the sleeve 7.

[0071] In this embodiment, the sleeve 7 is used to detachably fix the insulating rod.

[0072] In an optional embodiment of this utility model, the weeding device for ultra-high voltage converter stations further includes:

[0073] The spiked rake 8 is located at one end of the main frame 1.

[0074] The spiked rake 8 includes: a connecting rod 81 detachably connected to one end of the main frame 1 and spiked teeth 82 fixedly connected to the other end of the connecting rod 81.

[0075] In this embodiment, the spiked rake 8 is detachably connected to the main frame 1. The spiked rake 8 is used to remove the cut grass, preventing grass seeds from continuing to reproduce and preventing the cut weeds from falling onto the equipment due to strong winds or other factors, thus maintaining the cleanliness and aesthetics of the factory area.
