Problems solved by technology

[0003] The anti-bird device widely used at present is the anti-bird thorn, which has the following disadvantages during use: 1. The needle needs to be unfolded during installation, and the deployment process is time-consuming and laborious; 2. The protection radius cannot be adjusted, and the protection range is fixed. In some places, multiple anti-bird thorns need to be installed to ensure the protective effect; 3. Since the anti-bird thorns are of an unfolded structure, when the line is powered off for maintenance, the anti-bird thorns will hinder the work of the maintenance personnel when the maintenance personnel repair the wires. Manually bind it temporarily, and after the inspection is completed, it is necessary to re-deploy the anti-bird thorn needle. After re-expanding, the protection radius of the anti-bird thorn will be reduced, which will not only increase labor intensity, but also create new safety hazards

Embodiment 1

[0031] A new type of bird protection device for transmission lines in this embodiment, refer to the attached Figure 1-5 , comprising a central axis 8 with a fixed base 9 at the bottom, an expandable and retractable anti-bird thorn mechanism installed on the height direction of the central axis 8, and an adjusting mechanism for adjusting the protection radius of the anti-bird thorn mechanism.

[0032] Wherein, the adjustment mechanism includes a lancet fixed ring 2 installed on the central shaft 8 and positioned close to the hemisphere 1, and a pricker sliding ring 5 that can slide up and down along the height direction of the central shaft 8. The central shaft 8 is provided with a plurality of The positioning mechanism that fixes the lancet sliding ring 5 at the current position, the positioning mechanism includes a plurality of spaced limit adjustment holes 7 opened on the central axis 8, and pins 6 that can be inserted into the limit adjustment holes 7, the pins The length ...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that: the top of the central axis 8 is equipped with a hemispherical body 1 for preventing birds from staying and nesting, and the hemispherical body 1 is made of metal material.

[0036] working principle:

[0037] When in use, the central shaft 8 is used as a support, the lower end of the central shaft 8 is connected to the fixed base 9, the top of the central shaft 8 is connected to the sphere 1, the needle fixing ring 2 is fixed on the bottom of the hemisphere 1, the top of the central shaft 8, and the needle sliding ring 5 are set on the central axis 8 and can move up and down along the central axis 8. The middle part of the central axis 8 is provided with a limit adjustment hole 7. The limit adjustment hole 7 is a circular hole passing through the central axis 8. The key-shaped pin 6 can Insert the limit adjustment hole 7, when the key-shaped pin 6 is inserted into the limit adjustment hole 7 of different ...

Abstract

The invention relates to a novel bird damage prevention device for an electric transmission line, and belongs to the technical field of bird damage prevention devices for electric transmission lines. By the novel bird damage prevention device for the electric transmission line, repair of the electric transmission line is facilitated. The novel bird damage prevention device for the electric transmission line comprises a central shaft provided with a fixed base, wherein a stretchable and retractable bird stabbing prevention mechanism and an adjusting mechanism are mounted on the central shaft in the height direction; and the adjusting mechanism is used for adjusting the protection radius of the bird stabbing prevention mechanism. The novel bird damage prevention device for the electric transmission line is adjustable in protection range and convenient to mount, and can be closed when repaired.

Description

technical field [0001] The invention relates to a novel anti-bird damage device for power transmission lines, which is convenient for maintenance of power transmission lines and belongs to the technical field of anti-bird damage devices for power transmission lines. Background technique [0002] In order to prevent faults such as guano flashover and bird nest short-circuit caused by birds staying on the transmission line towers, the power department will install bird-proof devices on the crossarms and insulators of the transmission line towers. [0003] The anti-bird device widely used at present is the anti-bird thorn, which has the following disadvantages during use: 1. The needle needs to be unfolded during installation, and the deployment process is time-consuming and laborious; 2. The protection radius cannot be adjusted, and the protection range is fixed. In some places, multiple anti-bird thorns need to be installed to ensure the protective effect; 3. Since the anti-b...
