Description

Technical Field

[0001] The utility model relates to the technical field of power transmission lines, in particular to a protective structure for an overhead power transmission line. Background Art

[0002] Overhead transmission lines are used to conduct electric current and transmit electrical energy. The conductors should have good electrical conductivity, sufficient mechanical strength and corrosion resistance. Commonly used conductor materials are copper, aluminum and steel. Among them, aluminum is widely used in overhead lines due to its good electrical conductivity, low specific gravity and low price.

[0003] In the prior art, transmission lines are generally fixed by line clips. However, there is a certain distance between two adjacent groups of electric poles, which makes it impossible for the transmission lines to remain straight. They will sink to a certain extent, causing the transmission lines to sway to a certain extent under the action of wind. The swaying can easily cause friction between the transmission lines and the line clips, thereby causing damage to the transmission lines. For this reason, we propose a protective structure for overhead transmission lines. Utility Model Content

[0006] Preferably, the shock absorbing member comprises a damping telescopic member and a spring, the spring is sleeved on the outside of the damping telescopic member, and two ends of the damping telescopic member are movably connected to the first supporting member and the limiting member respectively.

[0007] Preferably, the limit member includes a limit seat and a pulley, the limit seat is a hollow structural member, one side of the limit seat is movably connected to one end of the damping telescopic member, two groups of pulleys are symmetrically installed in the inner cavity of the limit seat, and the transmission line body passes between the two groups of pulleys.

[0009] Preferably, two groups of limiting rods are symmetrically installed at both ends of the clamping block, and the two groups of limiting rods penetrate the second supporting member and are slidably connected thereto.

[0010] Preferably, two groups of positioning holes are symmetrically formed at both ends of the first support member.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model tightens the power transmission line body penetrating the second support member through an adjusting component to prevent it from shaking. Both ends of the power transmission line body pass through the limiter, and the limiter is connected to the first support member through a shock-absorbing member. When the power transmission line body swings, the shock-absorbing member is used to offset the force, so that the connection between the power transmission line body and the second support member is not prone to swing and friction. Compared with the prior art, the wear of the connection between the power transmission line body and the second support member is reduced, and the power transmission line body is not easily damaged, thereby improving the protection effect of the power transmission line body.

[0014] 3. The utility model can adjust the position of the clamp in the inner cavity of the second support member by rotating the adjusting bolt, which is threadedly connected to the second support member so that the bolt can penetrate into the inner cavity of the second support member or gradually detach from the inner cavity of the second support member. The limit rod penetrates the second support member and is slidably connected to the second support member, so as to limit the clamp and improve the sliding stability of the clamp in the second support member.

[0022] In this embodiment, the transmission line body 3 penetrating the second support member 2 is tightened by an adjusting component to prevent it from shaking, and both ends of the transmission line body 3 pass through the limiter 4, and the limiter 4 is connected to the first support member 1 by a shock absorber. When the transmission line body 3 swings, the shock absorber is used to offset the force, so that the connection between the transmission line body 3 and the second support member 2 is not prone to swinging and friction. Compared with the prior art, the wear of the connection between the transmission line body 3 and the second support member 2 is reduced, and the transmission line body 3 is not easily damaged, thereby improving the protection effect of the transmission line body 3.

[0024] In this embodiment, the limit seat 7 is a hollow structural member that can drain water and is not easily affected by rain. Passing the transmission line body 3 between the two sets of rotatable pulleys 8 can reduce the wear between the limit member 4 and the transmission line body 3. The damping telescopic member 5 is provided with a spring 6 on the outside to form a shock-absorbing member that can offset the force generated by the shaking of the transmission line body 3, thereby preventing friction from occurring between the transmission line body 3 and the second support member 2, thereby improving the protection of the transmission line body 3.
