Technical Field

[0001] This utility model relates to the field of wind farm collector lines technology, specifically a single-phase grounding device for wind farm collector lines. Background Technology

[0002] As is well known, in wind farms, wind turbines transmit the generated electricity to the power grid through collector lines. To ensure the safe and stable operation of the power system, effective grounding protection measures must be taken. Single-phase grounding is one of the most common faults in power systems, which can lead to equipment damage, power outages, and even personal injury accidents. Therefore, a reliable and efficient single-phase grounding protection device is crucial for the collector lines of wind farms. Some traditional devices may require a large operating space and additional tools or manpower during installation, increasing installation difficulty and time costs. Especially in complex terrain conditions, such as mountainous areas, traditional devices struggle to guarantee sufficient stability. Displacement can affect the grounding effect and even create safety hazards. If it is necessary to reorganize the lines or move the installation box, the disassembly process is complex and time-consuming, affecting work efficiency. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model relates to a single-phase grounding device for a wind farm collector line, comprising a mounting box 1. The bottom of the mounting box 1 is provided with a positioning mechanism. A mounting hole is formed at the bottom of the mounting box 1, and an adjusting tube 2 is provided on the mounting hole. A spiral nail 3 is provided at the bottom end of the adjusting tube 2. A sealed bearing 4 is provided between the adjusting tube 2 and the mounting box 1. An adjusting gear 5 is provided on the adjusting tube 2. An adjusting hole is formed at the top of the mounting box 1, and an adjusting column 6 is provided on the adjusting hole. An mounting gear 7 and a fixing bevel tooth 8 are provided on the adjusting column 6. Gear 7 meshes with the adjusting gear 5. A toothed ring 9 is provided between the adjusting hole and the top of the inner wall of the mounting box 1. The fixed bevel gear 8 meshes and abuts against the toothed ring 9. A bearing seat 10 is provided at the bottom of the adjusting column 6. An elastic support mechanism is provided between the bearing seat 10 and the interior of the mounting box 1. A wiring conduit 11 is provided at the top of the mounting box 1. In this embodiment, the column is placed on the ground at a designated location using a positioning mechanism. The wiring is fixed to the adjusting pipe 2 using a wiring conduit. Then, the spiral nail 3 is aligned with the ground, and the adjusting column 6 is pushed downwards. The adjusting column 6 drives the fixed bevel gear 8 and the mounting gear 7 to move. The fixed bevel gear 8 disengages from the gear ring 9, while the mounting gear 7 remains engaged with the adjusting gear 5. Rotating the adjusting column 6 causes the mounting gear 7 to rotate the adjusting gear 5, which in turn rotates the adjusting tube 2. The spiral nail 3 rotates and inserts into the ground, thus firmly anchoring the mounting box 1 to the ground. The spiral nail 3, located in the ground, is positioned by a positioning mechanism to ensure the mounting box 1 remains stable on the ground. This allows the line to be connected to the ground through the adjusting tube 2 and the spiral nail 3, providing single-phase grounding protection for the wind farm's collector lines. Releasing the adjusting column 6 provides an upward elastic support mechanism, allowing the fixed bevel gear 8 to engage with the gear ring 9, ensuring the adjusting column 6 does not shift at an angle and guaranteeing the stability of the spiral nail 3. The spiral nail 3 is firmly inserted into the soil, ensuring the mounting box 1 is securely fixed to the ground. Installation is convenient. When it is necessary to remove the mounting box 1 to tidy up the lines, pressing the adjusting column 6 and rotating it in the opposite direction causes the spiral nail 3 to rotate in the opposite direction and leave the ground, facilitating quick removal.

[0024] In this solution, the elastic support mechanism includes an elastic component 12, which is installed at the bottom of the inner side of the mounting box 1. A lifting plate 13 is provided between the top of the elastic component 12 and the bearing seat 10. A guide mechanism is provided between the lifting plate 13 and the inner wall of the mounting box 1. The elastic component 12 provides elastic support for the lifting plate 13, which in turn provides elastic support for the adjusting column 6 through the bearing seat 10. This allows the bevel teeth 8 to be securely engaged against the toothed ring 9. The guide mechanism further improves the linear lifting stability of the lifting plate 13.

[0025] In this solution, the guiding mechanism includes a guide hole and a guide post 14. The guide hole is opened on one side of the lifting plate 13, and the guide post 14 is installed on the inner wall of the mounting box 1. The guide post 14 passes through the guide hole. By passing the guide post 14 through the guide hole of the lifting plate 13, the linear lifting stability of the lifting plate 13 can be improved.

[0026] In this design, both the guide hole and the guide post 14 are T-shaped. The T-shaped guide post 14 and the guide hole prevent the guide post 14 from detaching from the guide hole and improve the stable guiding performance between the guide post 14 and the guide hole.

[0027] In this design, a sealing sleeve 15 is provided between the adjusting column 6 and the adjusting hole, which can improve the sealing performance between the adjusting column 6 and the adjusting hole.

[0028] In this design, a mounting bearing 16 is provided between the top end of the regulating tube 2 and the interior of the mounting box 1, which can further improve the rotational stability of the regulating tube 2.

[0029] In this solution, the positioning mechanism includes positioning posts 17, which are installed at the bottom of the mounting box 1. Multiple positioning posts 17 are provided. By using multiple positioning posts 17 at the bottom of the mounting box 1, the stability of the mounting box 1 when inserted into the ground can be improved.

[0030] In this design, the bottom end of the positioning post 17 is provided with a conical groove, which facilitates the insertion of the positioning post 17 into the ground.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
