Problems solved by technology

However, the device only protects the joint between the cross arm and the utility pole, and cannot protect the joint between the cross arm and the insulator. At the same time, the device contains stainless steel pipe clips and magnets, which are relatively heavy materials, which are not easy to carry outdoors. At the same time, due to the complex use environment , used in relatively humid areas especially affected by acid rain, stainless steel pipe clamps are susceptible to corrosion

Embodiment 1

[0040] This embodiment further illustrates the present invention by taking an anti-bird nesting device suitable for the middle part of the cross arm and the fixed position of the electric pole as an example.

[0041] like figure 1 , figure 2 As shown in the figure, the device is composed of two sheaths that can be butted together. The middle of the two sheaths is a vertical semi-cylindrical body 7 for closely fitting with the pole, which can connect the cross arm to the pole. All the gaps are blocked, effectively preventing birds from building nests here.

[0042] The sheath installed from the direction of the U-shaped screw of the electric pole is provided with a groove 8 that is protruding outwards that fits with the U-shaped screw, and the sheath installed from the direction of the cross arm of the electric pole is provided with an outwardly protruding groove that fits with the cross arm. slot 10. The outwardly protruding grooves 8 and 10 can ensure the firmness of the ...

Embodiment 2

[0049] This embodiment further illustrates the present invention by taking an anti-bird nesting device suitable for the fixed position of the end of the cross arm and the electric pole as an example.

[0050] like image 3 , Figure 4 , the side of the two sheaths and the end of the cross arm are matched with the fixed position of the electric pole, one side of the two sheaths is the seal 11 at the fixed end of the cross arm, and the other is the same as the embodiment 1.

Embodiment 3

[0052] The present embodiment is to further illustrate the installation method of the anti-bird nest building device, including the following steps:

[0053] (1) Apply for a work ticket and fill in the work ticket according to the power outage plan and maintenance plan;

[0054] (2) Start climbing the pole. After verifying that the double name of the line is correct, check that the climbing tools such as seat belts and foot buckles are qualified. Under the supervision of a special person, carry the transfer rope to the cross arm, fasten the seat belt, and hang the pulley on the upper wire. connection with the insulator;

[0055] (3) Install anti-bird nesting device

[0056] ①The ground crew under the pole transmits materials, including the side shield of the cross arm and a section of aluminum stranded wire for temporary binding;

[0057] ②The staff on the pole temporarily binds the side shield of the cross arm to the cross arm;

[0058] ③The ground crew under the pole pass...

Abstract

The invention discloses an electric pole cross arm anti-bird nest building device and an installation method. The device includes two sheaths that can be butted together, the two sheaths are provided with outward protrusions for closely fitting with the electric pole, and the side edges of the two sheaths are provided with a gap at the contact part of the bottom of the insulator, The shape of the gap is matched with the contact part of the bottom of the insulator, the edge with the gap is a baffle plate, and the baffle plate is used to closely fit the contact part of the bottom of the insulator. Install the butt on the pole from the direction of the cross-arm fixing device and the direction of the cross-arm respectively. The installation method of the device is simple in steps, and only needs one person to work on the pole. The device can simultaneously seal the parts where birds often build their nests on the pole, that is, the joint between the cross arm and the pole, and the gap between the cross arm and the insulator. The device is firmly fixed and ensures the transmission line. safe operation.

Description

technical field [0001] The invention relates to an electric pole cross-arm anti-bird nest building device and an installation method, which belong to the field of electric equipment manufacturing. Background technique [0002] With the rapid development of economy and society, users have put forward higher requirements for the reliability of power supply. At present, birds build more nests on 35kV poles. Because the nests contain conductive objects such as iron wires, or when it rains, the bird's nest becomes a conductive object due to the rain, which may cause circuit tripping and affect the reliability of power supply. . Birds' nest building has the greatest impact on the line erected by the cross-arm insulator pole tower. From our long-term operation and maintenance experience, we know that when birds build their nests, they are mainly inserted in the gaps between the cross-arm and the pole, and the cross-arm and the insulator. Twigs or iron wires prop up the bird's nes...
