[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] according to Figure 1 、 2 As shown in Figures 3 and 4, a transmission tower grounding device is proposed in this embodiment, including a pile body 1 and a copper busbar frame 2. A plurality of grounding bodies 7 are arranged in the copper busbar frame 2. Two adjacent grounding bodies 7 are connected to each other through a conductive wire 8. The copper busbar frame 2 is connected to the grounding body 7 through the conductive wire 8.

[0024] The copper busbar frame 2 and the grounding elements 7 are buried deep underground. Conductive wires 8 connect the grounding elements 7 in series, forming a mesh-like structure. This grounding network effectively prevents lightning strikes from damaging the power system. In the event of a lightning strike, the grounding network directs the lightning into the earth, preventing damage to power equipment and transmission lines. It also reduces static electricity accumulation, preventing accidents caused by electrostatic discharge.

[0025] A galvanized flat steel 3 is provided between the pile body 1 and the copper busbar frame 2. One end of the galvanized flat steel 3 is fixedly connected to the copper busbar frame 2, and the other end of the galvanized flat steel 3 is fixedly connected to the frame structure provided at the upper end of the pile body 1.

[0026] The pile body 1 is buried deep underground, and the frame structure at the upper end of the pile body 1 is exposed and fixed to the support legs at the bottom of the transmission tower. The current transmitted from the upper end of the frame structure can be introduced into the grounding network through the galvanized flat steel 3, so that the current is quickly conducted into the earth.

[0027] The copper busbar frame 2 and the galvanized flat steel 3 both include multiple plate segments 31 that are spliced ​​together. Two adjacent plate segments 31 are welded and fixed. The overlap of the plate segments 31 on the grounding device is completed by welding. Since the welding points are located at the seams between the plate segments 31 and the plate segments 31, if the welded plate segments 31 collide during laying, the welding points are likely to break, which in turn affects the safety of the entire grounding device. A fastening sleeve is provided at the seam between the two plate segments 31, and the fastening sleeve is detachably connected to the plate segment 31. The fastening sleeve is placed at the seam between the two plate segments 31 to protect the plate segment 31 and keep the two plate segments 31 in a tightly attached state at all times. The detachable installation method of the fastening sleeve makes it easy to disassemble and replace.

[0028] See also Figure 3 It should be further explained that one end of the plate segment 31 is placed on the upper end surface of the other plate segment 31, and the joints of the two plate segments 31 are fixed by welding.

[0029] More specifically, the fastening sleeve includes a rectangular hoop 9 that is sleeved on the outside of two adjacent plate sections 31. A first fastener is provided at the upper end of the rectangular hoop 9, a second fastener is provided on one side of the rectangular hoop 9, and a hoop notch 12 is opened on the side of the rectangular hoop 9 away from the second fastener.

[0030] After the plate segments 31 are welded together, the rectangular hoop 9 is placed on the outside of the plate segments 31. The first fastener is used to press the two plate segments 31 together from the upper end surface of the plate segments 31. The second fastener is used to secure the plate segments 31 again from the side. The hoop notch 12 on the other side of the rectangular hoop 9 allows the user to easily observe the weld condition at the joint between the plate segments 31.

[0031] About the first fastener:

[0032] The first fastener includes at least one first positioning bolt 13, which is installed at the upper end of the rectangular hoop 9. The first positioning bolt 13 penetrates into the rectangular hoop 9 and is threadedly connected to the rectangular hoop 9. After the two plate segments 31 are spliced ​​together, the rectangular hoop 9 is placed on the outside of the two plate segments 31, and the first positioning bolt 13 at the upper end of the rectangular hoop 9 is tightened. The first positioning bolt 13 squeezes the plate segments 31 from the upper end, firmly fixing the plate segments 31 to each other.

[0033] Regarding the second fastener:

[0034] The second fasteners include two second fixing bolts 14, which are installed on the side of the rectangular hoop 9 away from the hoop notch 12. The second fixing bolts 14 penetrate into the rectangular hoop 9 and are threadedly connected to the rectangular hoop 9. After the two plate segments 31 are spliced ​​together, the rectangular hoop 9 is placed on the outside of the two plate segments 31, and the two second fixing bolts 14 on the sides of the rectangular hoop 9 are tightened. The two second fixing bolts 14 respectively squeeze the plate segments 31 from the sides of the two plate segments 31, so that the plate segments 31 remain in a close contact with the rectangular hoop 9.

[0035] In a preferred embodiment, a reinforcing plate 10 is provided at the upper end of the rectangular hoop 9. The reinforcing plate 10 is fixedly connected to the side of the rectangular hoop 9 away from the hoop notch 12. A triangular rib 11 is provided at the connection between the reinforcing plate 10 and the rectangular hoop 9. The reinforcing plate 10 and the triangular rib 11 fixedly connected to the side of the rectangular hoop 9 act as reinforcing ribs, which can effectively improve the deformation resistance of the bend of the rectangular hoop 9 and strengthen the structural strength of the rectangular hoop 9.

[0036] About the frame structure:

[0037] The frame structure includes a bolt plate bracket 4, with multiple diagonal bracing plates 5 provided at the upper end of the bolt plate bracket 4. The lower end of the diagonal bracing plates 5 has several bolt holes, which are threadedly connected to the fixing bolts 6 assembled on the bolt plate bracket 4. The bolt plate bracket 4 is fixedly connected to the upper end of the pile body 1, and the bottom of the bolt plate bracket 4 is deeply buried in the pile body 1. The diagonal bracing plates 5 are fixed to the bolt plate bracket 4 by bolt connection, which is used to facilitate the staff to assemble the frame structure.

[0038] How this application works:

[0039] The copper busbar frame 2 and each grounding body 7 are buried deep underground, and each conducting wire 8 connects each grounding body 7 in series to form a grounding body with a mesh structure.

[0040] The pile body 1 is buried deep underground, and the frame structure at the upper end of the pile body 1 is exposed and fixed to the support legs at the bottom of the transmission tower. The current transmitted from the upper end of the frame structure can be introduced into the grounding network through the galvanized flat steel 3, so that the current is quickly conducted into the earth.

[0041] The overlap of the upper plate section 31 of the grounding device is completed by welding. The fastening sleeve is sleeved on the joint of the two plate sections 31, which can protect the plate sections 31 and keep the two plate sections 31 in a close contact state at all times. The fastening sleeve is detachable for installation, which is convenient for disassembly and replacement.
