Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and specifically relates to a modular grounding device for power line towers. Background Technology

[0002] Grounding devices for power transmission line towers are crucial safety equipment in power systems. They primarily connect the tower structure electrically to the earth, ensuring that dangerous currents are promptly conducted to the ground in the event of lightning strikes or faults, protecting equipment and personnel. Traditional grounding devices for power transmission line towers typically employ an integrated structural design, mainly composed of a grounding electrode, connecting conductors, and fixing components. The grounding electrode is often made of steel pipe or angle steel, connected by welding or bolts to form a unified structure. In practical applications, this traditional grounding device structure presents several problems. First, its complex structure and lack of standardized design among components lead to high production costs and difficulties in quality control. Second, installation and maintenance are difficult. Due to the limitations of the integrated structure, on-site installation requires numerous specialized tools and technicians, and maintenance and replacement necessitate complete disassembly, which is time-consuming and labor-intensive. Third, its low modularity prevents flexible configuration and adjustment according to different installation environments and technical requirements. Furthermore, traditional grounding devices have poor adaptability, failing to meet the needs of varying geological conditions and installation requirements. While some modular approaches exist in existing technologies, they primarily focus on the assembly of grounding electrodes, lacking a modular design for the entire grounding system. This results in problems such as complex installation, difficult maintenance, and low standardization. Therefore, there is an urgent need to develop a grounding device for power transmission line towers that is simple in structure, easy to install, highly modular, and adaptable to meet the higher requirements of modern power systems for grounding devices.

[0004] This utility model is implemented as follows: This utility model provides a modular grounding device for power transmission line towers, comprising: a grounding body, a connecting component, a fixing module, a conductive ring, and an adjusting mechanism; the grounding body is a cylindrical structure, with a connecting surface at the top and a threaded hole on the connecting surface, into which a bolt is threaded; the connecting component includes a connecting plate, a connecting rod, and a locking sleeve, the connecting plate being fixedly mounted on the connecting surface of the grounding body, a through hole in the middle of the connecting plate, the connecting rod passing through the through hole, and a locking sleeve threadedly connected to the upper end of the connecting rod; The fixing module includes a fixing seat and a clamping plate. The fixing seat is fixedly installed on the outer wall of the grounding body in a ring structure. The inner side wall of the fixing seat is provided with a guide groove, and the clamping plate is slidably connected in the guide groove. The conductive ring has an annular structure, and its outer diameter is adapted to the inner diameter of the fixed base. The conductive ring is located outside the clamping plate. The adjustment mechanism includes an adjusting screw and an adjusting nut. One end of the adjusting screw is connected to the connecting surface through a bearing, and the other end of the adjusting screw passes through the clamping plate and is threadedly connected to the adjusting nut. The adjusting nut rotates to drive the clamping plate to slide in the guide groove, thereby adjusting the clamping force between the clamping plate and the conductive ring. The depth of the guide groove gradually increases from bottom to top.

[0005] The technical advantages of this utility model for a modular grounding device for power line towers are as follows: By setting up a combined structure of a grounding main body, connecting components, a fixing module, a conductive ring, and an adjusting mechanism, a modular design for the power line tower grounding device is achieved.

The design of the arc-shaped concave surface on the inner surface ensures good fit with the conductive ring, and the cooperation between the guide protrusion and the guide groove of the fixed seat ensures the smoothness and accuracy of the clamping plate movement, thus improving the overall clamping effect and service life.

[0016] Furthermore, the bottom of the grounding body is provided with a conical structure, the cone angle of which is 30 degrees to 60 degrees, and the height of the conical structure is one-quarter to one-third of the total height of the grounding body.

The specific cone angle design ensures sufficient contact area while ensuring convenient insertion. The reasonable setting of the height of the conical structure not only meets the functional requirements but also maintains the coordination of the overall structure, thereby improving the grounding effect and installation efficiency.

[0018] Furthermore, the connecting rod has a hexagonal cross-section in the middle, the length of which is 15 mm to 25 mm and the distance between opposite sides of the hexagon is 8 mm to 12 mm.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a hexagonal cross-section structure in the middle of the connecting rod, it facilitates tool operation during installation and maintenance.

The specific thickness design of the anti-corrosion coating ensures the protective effect while avoiding excessive cost increase. The use of trapezoidal thread improves the strength and wear resistance of the threaded connection. The specific pitch design ensures the accuracy and stability of the adjustment operation, and the overall reliability and durability of the adjusting mechanism are improved.
