Problems solved by technology

[0005] The purpose of the patent of the present invention is to provide a bird-proof device and a bird-proof method for transmission lines, which solves the technical problem of how to install the bird-proof device in a charged state, and uses SMC materials to make a fiberglass core as a supporting and connecting structure. It is covered with a layer of aging-resistant silicone rubber and fixed on the cross-arm of the transmission line tower insulator through the connection structure. It can not only protect the lower insulator from bird droppings, but also increase the air gap and prevent bird droppings from flashover. Operation Convenient, strong applicability, large protection area and long service life

Embodiment 1

[0037] see figure 1 , figure 2 and image 3 , a bird-proof device and bird-proof method for transmission lines, which are arranged on a transmission tower, a cross-arm 3 is arranged on the upper end of the transmission tower, and an insulator 5 is arranged below the cross-arm 3, including a contact connection with the cross-arm 3 and used for preventing bird droppings The shielding plate 4, the anti-skid pressure plate 2 arranged on the upper end surface of the shielding plate 4 and the T-shaped bolt 1, the T-shaped bolt 1 passes through the anti-skid pressure plate 2 and fixes the shielding plate 4 on the cross arm 3;

[0038] see Figure 5 The baffle plate 4 includes a core frame and elastic silicone rubber coated on the outside of the core frame. The core frame is made of SMC material, and the elastic silicone rubber is vulcanized at high temperature. Silicone rubber reinforcement 6.

[0039] The shading plate 4 is in contact with the cross arm 3 , and the shading plat...

Embodiment 2

[0059] see Figure 4 The T-bolt 1 passes through the shielding plate 4 and rotates 90°, the groove at the lower end of the T-bolt 1 is buckled on one side of the angle steel of the cross-arm 3, and the shielding plate 4 is fixed on the cross-arm 3 by the anti-slip pressure plate 2.

[0060] In the installation method in this embodiment, after the T-shaped connecting bolt passes through the anti-bird droppings shielding plate 4, it is rotated 90°, and the groove at the lower end of the T-shaped connecting bolt is buckled on one side of the angle steel of the cross arm 3, and then the Anti-bird droppings shielding plate 4 is fixed on the top of cross arm 3. The anti-guano shielding plate 4 is composed of multiple pieces assembled, and can be combined arbitrarily according to the length of the cross-arm 3 .

Abstract

The invention provides an anti-bird device for a power transmission line and an anti-bird method of the device. The device is arranged on a power transmission tower, a cross arm is arranged at the upper end of the power transmission tower, an insulator is arranged under the cross arm, the device comprises a baffle plate which is in contact connection with the cross arm and used for preventing birddroppings, an anti-skid pressing plate arranged on the upper end face of the baffle plate and a T-shaped bolt, and the T-shaped bolt penetrates through the anti-skid pressing plate and fixes the baffle plate to the cross arm; the shielding plate comprises a core framework and elastic silicon rubber wrapping the core framework, the core framework is made of an SMC material, and the elastic siliconrubber is formed through high-temperature vulcanization. According to the anti-bird device for the power transmission line and the anti-bird method of the anti-bird device, the anti-bird device can be installed in an electrified state, the insulator under the anti-bird device can be protected against bird droppings, the effects of enlarging air gaps and preventing bird droppings from flashover can be achieved, operation is convenient, applicability is high, the protection area is large, and the service life is long.

Description

technical field [0001] The patent of the present invention belongs to the technical field of utility poles, and in particular relates to a bird-proof device for power transmission lines and a bird-proof method thereof. Background technique [0002] With the improvement of the ecological environment and the enhancement of people's awareness of the protection of wild animals, the species and number of birds continue to increase. However, birds often build their nests above the insulators of overhead transmission lines, and breed and survive on them. During this period, they produce a large amount of feces, which cause two types of short-circuit faults on the transmission lines. One is that a large amount of bird droppings will drip along the insulators, seriously polluting the insulators, and because the bird droppings contain salts, which are conductors, when there are too many bird droppings, the insulation performance of the insulators will fail, causing the line to trip. ...
