Description

Technical Field

[0001] This utility model relates to the field of overhead power transmission line technology, specifically to an overhead power transmission line conductor sag adjustment device. Background Technology

[0002] With the continuous advancement of my country's power technology, high-voltage transmission lines are used to transmit power to areas with high electricity consumption. These transmission lines are located at high altitudes, at a certain height from the ground.

[0003] When using overhead power transmission, the distance between two adjacent high-voltage transmission towers is long and the span of the transmission line is large, causing the middle section of the transmission line to sag in an arc. Therefore, it is necessary to straighten the transmission line as much as possible during the laying process. However, the transmission line will experience thermal expansion and contraction during the changing seasons, which will cause the transmission line to sag excessively or shrink. The already fixed transmission line cannot be effectively adjusted. If the force at both ends of the transmission line is too great, it will put too much tension on the transmission tower. If it is too small, it will cause the transmission line to sag excessively, which is not conducive to the transmission of electricity. Utility Model Content

[0004] The purpose of this utility model is to provide a device for adjusting the sag of overhead transmission line conductors. The transmission line passes through a rotating shaft from one side, winds up and down around the surface of a support plate on two connecting shafts, and then exits from the rotating shaft on the other side. When the transmission line expands or contracts, the main motor can be started to rotate the left rotating plate and the right rotating plate of the connecting shaft, thereby winding or loosening the transmission line and adjusting its length. In addition, an electric rod and a support plate are provided on the connecting shaft. After the electric rod is started, the distance between the support plate and the connecting shaft can be changed, thereby further adjusting the transmission line on the support plate with a larger adjustment range.

There are two connecting shafts 402, which are symmetrically distributed front and back. The electric rod 403 and the insulating sleeve 404 are fixedly connected to the circumference of the connecting shaft 402. The electric rod 403 is located inside the insulating sleeve 404. The end of the electric rod 403 away from the connecting shaft 402 is fixedly connected to the support plate 405. The end of the insulating sleeve 404 away from the connecting shaft 402 is connected to the support plate 405.

Multiple electric rods 403, insulating sleeves 404, and support plates 405 are provided and evenly distributed on the outside of the connecting shaft 402. A left-turning plate 406 is fixedly connected to the left side wall of the connecting shaft 402. The power transmission line runs around the surface of the support plate 405 of the front and rear connecting shafts 402. When the right-turning plate 401 and the left-turning plate 406 rotate, the power transmission line on the surface of the supporting plate 405 can be further wound or loosened, thereby adjusting the power transmission line. The electric rod 403 can also be activated to change the distance between the support plate 405 and the connecting shaft 402, thereby further adjusting the sag of the power transmission line.

[0023] The left side of the left-turning plate 406 is provided with a main motor 407 and an insulation box 408. The main motor 407 is located inside the insulation box 408.
