Description

Technical Field

[0001] The utility model belongs to the technical field of lightning protection for distribution line poles, and in particular relates to a lightning protection distribution line pole tower structure. Background Art

[0002] Distribution line towers are supports used to support transmission lines in overhead transmission lines. Pole towers are mostly made of steel or reinforced concrete and are the main supporting structures of overhead transmission lines. They can erect high-voltage distribution lines to a specific height to lift them off the ground, reduce the impact of electricity on the underlying buildings and people, and ensure the safety of power distribution work. Distribution line towers are erected higher and use more metal, making them more susceptible to lightning strikes. In order to reduce the damage caused by lightning strikes to distribution line tower structures, lightning rod structures are usually used to guide lightning.

[0003] At present, the existing lightning rods for distribution line towers have poor stability when in use. When encountering strong winds, they are prone to swaying, which increases the friction between the lightning rod and the fixed structure, making the gap larger, causing the lightning rod to fall. In addition, the shaking of the lightning rod is also prone to cause a lightning strike when attracting lightning, causing damage to the structure on the distribution line tower, affecting the use effect of the lightning rod for lightning protection of the distribution line tower. To this end, we provide a lightning protection distribution line tower structure to solve the above problems. Utility Model Content

The outer surface of each mounting bolt 312 is sleeved with a gasket 313, and the bottom surface of each gasket 313 is in contact with the upper surface of the mounting plate 311. The gasket 313 can increase the friction between the mounting bolt 312 and the mounting plate 311, making it difficult for the mounting bolt 312 to loosen, thereby improving the firmness of the fit between the mounting bolt 312 and the mounting plate 311.

[0028] See also Figure 2 As shown, the bottom end of the lightning rod 2 is fixedly connected with a fixing plate 314, and the internal thread of the fixing plate 314 is connected with six fixing bolts 315, and the bottom end of each fixing bolt 315 passes through the fixing plate 314 and extends to the inside of the base 1, and each fixing bolt 315 is threadedly connected with the base 1. The fixing bolts 315 cooperate with the fixing plate 314 to fix the lightning rod 2 to the base 1, ensuring that the lightning rod 2 can be smoothly installed in place.

[0029] See also Figure 3 and Figure 4 As shown, the outer surface of each connecting tube 302 is sleeved with a rotating sleeve 304, the upper surface of each rotating sleeve 304 is fixedly connected with a threaded tube 305, each threaded tube 305 is threadedly connected to the screw 303, and the outer surface of each connecting seat 301 is fixedly connected with two reinforcing blocks 316, the bottom surface of each reinforcing block 316 is fixedly connected to the upper surface of the base 1, and the reinforcing blocks 316 can increase the connection firmness between the connecting seat 301 and the base 1 to prevent the connecting seat 301 and the base 1 from loosening.

[0030] See also Figure 2 , Figure 3 and Figure 4 As shown, the top of each screw rod 303 is fixedly connected to a connecting rod 306, and the top of each connecting rod 306 is movably hinged to a fixing seat 307 through a pin shaft, and the inner wall of each fixing seat 307 is fixedly connected to the outer surface of the lightning rod 2.

The sliding ring 317 can limit the position of the rotating sleeve 304 without affecting the smooth rotation of the rotating sleeve 304, so that the rotating sleeve 304 can be located at a suitable position outside the connecting tube 302.

[0031] See also Figure 1 and Figure 2As shown, the upper surface of the ceramic plate 308 is fixedly connected with an arc-shaped rubber disk 309, the inner wall of the arc-shaped rubber disk 309 contacts the outer surface of the lightning rod 2, the outer surface of the lightning rod 2 is fixedly connected with a limiting disk 310, the upper surface of the limiting disk 310 contacts the bottom surface of the ceramic plate 308, and four limiting bolts 318 are clamped inside the arc-shaped rubber disk 309.

[0032] The specific working principle and method of use of the utility model are as follows: when in use, first fix the base 1 on the distribution line tower structure in conjunction with the mounting plate 311, the mounting bolts 312 and the gasket 313 to prepare for the subsequent installation of the lightning rod 2, and then use the fixing bolts 315 to cooperate with the fixing plate 314 to fix the lightning rod 2 to the base 1.

Finally, through the limitation of the ceramic plate 308 in conjunction with the limiting plate 310 and the limiting bolt 318, the insulation of the ceramic plate 308 can be used to further reduce the risk of winding strike of the lightning rod 2, and the arc-shaped rubber plate 309 can further increase the insulation effect of the ceramic plate 308, so that the lightning current will only flow through the lightning rod 2, and it is not easy to cause lightning damage to the distribution line tower. At the same time, the arc of the arc-shaped rubber plate 309 can also prevent too much rain from staying on the ceramic plate 308, so that when lightning strikes the lightning rod 2, it is not easy to be diverted due to rain, which further improves the use performance of the lightning protection lightning rod 2 for the distribution line tower.
