[0002] The primary function of the grounding device at the Shagohuang New Energy Base is to ensure the safe operation of new energy power generation facilities and the stability of the power system. The grounding device connects the metal casing of equipment, cable shielding, etc., to the earth, providing a low-impedance electrical path. This prevents electric shock hazards caused by insulation damage and reduces the impact of electromagnetic interference on the equipment. The grounding device typically consists of a grounding electrode and a grounding wire. The grounding electrode is a buried metal conductor used to form a good electrical connection with the earth; the grounding wire is the conductor connecting the equipment to the grounding electrode. The materials for the grounding device can be angle steel, steel pipe, copper plate, etc., and its depth and number are determined based on soil resistivity and equipment requirements. During installation, it is essential to ensure full contact between the grounding electrode and the earth to minimize contact resistance.

[0003] Referring to Chinese invention patent application publication number CN119482647A, a DC transmission topology for new energy sources in the isolated desert island of Shagolan, which involves the technical field of equipment related to the Shagolan base, the modular multilevel converter includes a positive converter and a negative converter. Each area of ​​the topology is connected to either the positive or negative converter to achieve short-distance collection lines. The positive and negative converters are connected by a 30-50km grounding line. This design fully considers the scenario of a wide distribution of various types of large-scale new energy sources in the Shagolan region. By using the existing grounding lines, a positive and negative polarity separation construction is proposed, which can achieve short-distance collection lines, improve system strength, and enable partial power transmission in the event of a sending-end fault, thereby reducing the power deficit of the receiving-end grid.

[0004] Referring to Chinese invention patent application publication number CN118920218A, a grounding method and device for wind farms in desert areas is disclosed, relating to the technical field of equipment in desert areas. This invention includes the following steps: S1: Surveying: conducting soil resistivity tests; S2: Designing an effective grounding system based on soil resistivity data; S3: Installing grounding components, placing them in predetermined positions; S4: Laying grounding wires: forming a grounding grid and connecting each grounding component. During use, the first movable groove on the limiting block is always positioned away from the ball bearing, ensuring the limiting block's restraining effect on the semi-elliptical movable groove, ensuring the tightness of the connection between the first and second connecting seats, thereby ensuring the wiring effect of the wires and the working effect of the grounding components.

[0043] 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.

[0044] Please see Figures 1-5The existing grounding device for the desert new energy base is inconvenient to adjust its height according to the site conditions or the depth of insertion into the ground. Furthermore, the grounding device is not easy to securely fix to the desert when it is installed on the desert. Also, the two ends of the grounding device are connected to the material, making it difficult to connect the material and the grounding device together. In order to solve this technical problem, this embodiment discloses the following technical content.

[0045] A connecting rod 2 is fixedly connected to the middle of the lower surface of the grounding connection ring 1, and a lifting mechanism is provided at the bottom of the connecting rod 2. The lifting mechanism is composed of a threaded rod 3, a threaded lifting rod 4 and a stabilizing bolt 5. The threaded rod 3 is fixedly connected to the outer end of the lower surface of the connecting rod 2, and the threaded lifting rod 4 is threadedly connected to the outer side of the threaded rod 3. The stabilizing bolt 5 is threadedly connected to the front top of the threaded lifting rod 4.

The rear end of the stabilizing bolt 5 is threadedly connected to the threaded rod 3. A grounding tip 6 is fixedly connected to the bottom surface of the threaded lifting rod 4.

[0046] Before fixing the grounding device to the Shagohuang New Energy Base, the height of the bottom of the grounding device needs to be adjusted according to the site conditions. At this time, rotate the threaded lifting rod 4 so that the threaded lifting rod 4 rotates on the outside of the threaded rod. Adjust the distance between the bottom surface of the threaded lifting rod 4 and the bottom surface of the grounding connection ring 1. After adjusting the distance between the bottom surface of the threaded lifting rod 4 and the bottom surface of the grounding connection ring 1, use the fixing bolt 5 to pass through the top front end of the threaded lifting rod 4 and connect it to the threaded rod 3. The fixing bolt 5 fixes the threaded lifting rod 4 and the threaded rod 3 together. After adjusting the height of the bottom of the grounding device, insert the grounding device into the Shagohuang through the grounding tip 6. By adjusting the height of the bottom of the grounding device, the grounding device can be better installed and fixed according to the site conditions of Shagohuang, so that the installation and use effect of the grounding device is better.

[0047] The bottom of the lifting mechanism is provided with a balance crossbar 7, which is rotatably connected to the threaded lifting rod 4.

The balance crossbar 7 is fixed to the ground through the connecting through hole 9 and screws.

[0048] After inserting the grounding device into the sand dunes, it needs to be stably supported. At this time, rotate the balance bar 7 outward so that the outer surfaces of the balance bar 7 and the T-shaped stabilizing plate 8 contact the sand dune surface. Use a rod or other object to pass through the connecting through hole 9 opened at the middle of the outer end of the balance bar 7 and the middle of the outer end of the T-shaped stabilizing plate 8. Insert the rod through the connecting through hole 9 into the sand dunes to firmly fix the balance bar 7 and the T-shaped stabilizing plate 8 onto the sand dunes. After installing the balance bar 7 and the T-shaped stabilizing plate 8, cover the balance bar 7 and the T-shaped stabilizing plate 8 with sand to complete the installation of the bottom of the grounding device. Setting up the balance bar 7 and the T-shaped stabilizing plate 8 can increase the stability of the grounding device installed on the sand dunes, so that the grounding device can be firmly fixed on the sand dunes and avoid the grounding device being blown over by unstable sand or excessive wind.

Then, one end of the material is inserted into the material connection port 10 opened on the left and right sides of the grounding connection ring 1. Then, the welding connection ring 11 is moved so that the welding connection ring 11 is engaged with the groove opened on the inner side of the outer end of the material connection port 10. Finally, the welding mechanism is used to weld the grounding connection ring 1, the material connection port 10 and the outer end of the welding ring 11 together to make the connection between the grounding device and the material more stable.
