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] In this embodiment, the present invention is further clarified by taking the bird-preventing nest-building device suitable for the middle part of the cross arm and the fixed position of the electric pole as an example.

[0041] Such as figure 1 , figure 2 As shown, the device is composed of two sheaths that can be docked together. In the middle of the two sheaths is a vertical semi-cylindrical body 7 that is used to fit closely with the pole. All the gaps are blocked to effectively prevent birds from building nests here.

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

[0043] The sides of the two...

Embodiment 2

[0049] In this embodiment, the present invention is further clarified by taking the bird-preventing nest-building device applicable to the fixed position of the end of the cross arm and the electric pole as an example.

[0050] Such as image 3 , Figure 4 , the sides of the two sheaths and the ends of the cross-arm match the fixed position of the pole, one side of the two sheaths is a seal 11 at the fixed end of the cross-arm, and the others are the same as in Embodiment 1.

Embodiment 3

[0052] This embodiment is to further clarify 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 to climb the pole. After verifying that the double name of the line is correct, check that the climbing tools such as safety belts and foot buckles are qualified. The connection with the insulator;

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

[0056] ①Transfer materials by the ground crew under the pole, including the side shield of the cross arm and a section of aluminum strand for temporary binding;

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

[0058] ③The ground crew under the pole passes the U-shaped screw side shield;

[0059] ④ The staff on the pole removes the U-shaped screw side shield and installs it with the cross arm side shield....

Abstract

The invention discloses an electric pole cross arm device capable of preventing nesting of birds and an installation method thereof. The device comprises two protective sleeves which can be butted together, wherein the two protective sleeves are provided with outward bulges which are used for tightly fitting an electric pole, notches are formed in the contact parts between the side edges of the two protective sleeves and the bottom of an insulator, and the shapes of the notches are matched with the bottom contact parts of the insulator; the edges provided with the notches serve as baffles, thebaffles are used for tightly fitting the bottom contact parts of the insulator, a fixing device is arranged on the butt joint surfaces of the two protective sleeves, and the two protective sleeves are installed and butted on the electric pole separately in the direction of a cross arm fixing device and the direction of a cross arm. The installation method of the electric pole cross arm device issimple in procedure, and only one person needs to work on the electric rod. The electric pole cross arm device can simultaneously block all the gaps in the joint parts between the cross arm and the electric pole and the joint parts between the cross arm and the insulator, wherein birds often build nests at the joint parts, between the cross arm and the electric rod, on the electric pole; the electric pole cross arm device is firmly fixed, so that the safe operation of a power transmission line is ensured.

Description

technical field [0001] The invention relates to an electric pole cross-arm bird prevention 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 on the reliability level of power supply. At present, on 35kV poles, birds build many nests. Because the nests contain conductive objects such as iron wires, or when it rains, the rainwater wets the nests and turns the nests into conductive objects, which may cause the line to trip and affect the reliability of power supply. . The nesting of birds has the greatest impact on the lines erected by cross-arm insulators. Through our long-term operation and maintenance experience, we know that when birds build nests, they are mainly inserted into the gaps between the cross-arm and the pole, and between the cross-arm and the insulator. Branches or wires support the bird's ...
