Description

Technical Field

[0001] The invention relates to the technical field of power transmission lines, and in particular to a bird droppings prevention device for an insulator of a power transmission line. Background Art

[0002] With the improvement of the natural environment, bird activities are becoming more frequent. The insulators on high-voltage transmission lines are in an unobstructed natural environment for a long time. Birds often land on them, causing bird droppings to cover the insulators, which can easily lead to safety accidents such as insulator flashover leakage and short circuit. This increases the risk of tripping due to bird droppings. The work of bird damage control on transmission lines is becoming increasingly serious. Nowadays, some insulator products are installed with similar protective covers, but they are composed of two pieces of cover bodies connected together, and both hands are required to operate at the same time during installation. Since the insulator is at a high height from the ground, it is bound to increase the risk factor for operators. How to effectively reduce the scattering of bird droppings on cables has become an important task in transmission line management.

[0003] Traditional fiberglass bird-proof covers are made of two semicircles. Every time the transmission line is repaired or maintained, workers must remove the entire bird-proof cover. Because it is at high altitude, there is nowhere to put the temporarily removed fiberglass bird-proof cover, which greatly increases the difficulty and danger of the workers' tasks. Even if there is a place to put it down, it may fall to the ground because it is not fixed, and it is necessary to go down and pick it up again, which is time-consuming and laborious, and it may fall to the ground and break directly, causing property losses to the power supply company. Summary of the invention

[0004] The main purpose of the present invention is to provide a transmission line insulator bird droppings protection device, wherein the first bird-proof cover can be mounted on the second bird-proof cover under the action of gravity, so as to solve the problem that the work difficulty of personnel is increased due to the obstruction caused by the bird-proof cover during high-altitude operations, and also solve the problem that the bird-proof cover has nowhere to be placed when it is temporarily disassembled. While improving the efficiency, it also greatly reduces the safety problems caused by the bird-proof cover.

[0005] To achieve the above object, the technical solution adopted by the present invention is: A bird droppings prevention device for an insulator of a power transmission line comprises a shaft and a bird-proof cover, wherein the bird-proof cover comprises a first bird-proof cover and a second bird-proof cover, wherein the first bird-proof cover is connected to the shaft through a first fixing assembly, and the second bird-proof cover is arranged in an upper and lower staggered manner with the first bird-proof cover and fixed to the shaft, and the fixing assembly is used to prevent the first bird-proof cover from rotating relative to the shaft when tightened.

[0006] Furthermore, the fixing assembly includes a first semicircular tube clamp and a second semicircular tube clamp, the first semicircular tube clamp and the second semicircular tube clamp are fixed to the shaft body by bolts, and the first semicircular tube clamp is fixedly connected to the first bird-proof cover.

[0007] Furthermore, it also includes a shielding plate, which is located between the first bird-proof cover and the second bird-proof cover to block the gap between the first bird-proof cover and the second bird-proof cover.

[0008] Furthermore, baffles are respectively fixed on the opposite sides of the first bird-proof cover and the second bird-proof cover, the upper end of the baffle is fixed to the baffle of the first bird-proof cover, and the lower end of the baffle is in contact with the baffle of the second bird-proof cover.

[0009] Furthermore, the second bird-proof cover is fixed on the shaft body through a fixing assembly, a slot is provided at the bottom of the shield, and a second semicircular tube in the fixing assembly for fixing the second bird-proof cover is clamped in the slot.

[0010] Furthermore, the first bird-proofing cover and the second bird-proofing cover have the same structure, and the bird-proofing cover body formed therefrom is circular with the center of the circle arched upward.

[0011] Furthermore, strip reinforcement ribs are provided on the tops of the first bird-proof cover and the second bird-proof cover.

[0012] Furthermore, the bottoms of the first bird-proof cover and the second bird-proof cover are provided with semi-annular reinforcement ribs and triangular reinforcement ribs, and the triangular reinforcement ribs penetrate through the semi-annular reinforcement ribs.

[0013] Furthermore, the shield is made of elastic material.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The first bird-proof cover of the present invention can rotate around the shaft body when disassembled, so that the first bird-proof cover is located above the second bird-proof cover, and then the first bird-proof cover can be carried on the second bird-proof cover under the action of gravity, so as to solve the problem that the work difficulty of personnel is increased due to the obstruction caused by the bird-proof cover during high-altitude operations, and also solve the problem that the bird-proof cover has nowhere to be placed when it is temporarily disassembled. While improving efficiency, it also greatly reduces the safety problems caused by the bird-proof cover.

[0015] 2. The shield of the present invention can block the gap between the first bird-proof cover and the second bird-proof cover, thereby preventing bird droppings from falling onto the insulator through the gap.

[0016] 3. The shielding plate of the present invention contacts the baffle plate of the first bird-proof cover and the baffle plate of the second bird-proof cover respectively, so it can prevent the first bird-proof cover and the second bird-proof cover from rotating relative to each other when the bird-proof cover body is fixed on the shaft body, thereby improving the splicing stability of the first bird-proof cover and the second bird-proof cover.

[0017] 4. When the first bird-proof cover of the present invention is located above the second bird-proof cover, the shielding plate will contact the baffle plate of the second bird-proof cover. Since the second bird-proof cover is fixed in position, the first bird-proof cover cannot rotate due to the shielding plate, thereby preventing the first bird-proof cover from rotating after being mounted on the second bird-proof cover.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figure 1-7As shown, a transmission line insulator bird droppings prevention device includes a shaft body 3 and a bird-proof cover body, the bird-proof cover body includes a first bird-proof cover 1 and a second bird-proof cover 2, the first bird-proof cover 1 is connected to the shaft body 3 through a first fixing component 4, the second bird-proof cover 2 and the first bird-proof cover 1 are staggered up and down and the second bird-proof cover 2 is fixed on the shaft body 3, and the first fixing component 4 is used to prevent the first bird-proof cover 1 from rotating relative to the shaft body 3 when tightening.

[0028] In this embodiment, if Figure 1 and Figure 2 As shown, the first bird-proof cover 1 and the second bird-proof cover 2 have the same structure. The bird-proof cover body composed of the two is circular and the center of the circle is arched upward. The first bird-proof cover 1 and the second bird-proof cover 2 are semicircular fiberglass bird-proof covers. When installing the bird-proof cover body, first fix the shaft body 3 on the insulator, and then fix the first bird-proof cover 1 and the second bird-proof cover 2 on the shaft body 3 through the first fixing component 4 and the second fixing component respectively, and make the installation height of the first bird-proof cover 1 higher than the second bird-proof cover 2, and install them in staggered order. At this time, the first bird-proof cover 1 and the second bird-proof cover 2 cooperate with each other, as shown in FIG. Figure 1 As shown, bird droppings can be prevented from falling on the insulator, thereby avoiding safety accidents such as insulator flashover leakage and short circuit caused by bird droppings all over the insulator.

[0029] like Figure 3 and Figure 4 As shown, the first fixing component 4 and the second fixing component have the same structure, both including a first semicircular tube clamp 402 and a second semicircular tube clamp 401, the first semicircular tube clamp 402 and the second semicircular tube clamp 401 are fixed to the shaft body 3 by bolts 403, the bolts 403 are horn bolts, the first semicircular tube clamp 402 of the first fixing component 4 is fixedly connected to the first bird-proof cover 1, and the first semicircular tube clamp 402 of the second fixing component is fixedly connected to the second bird-proof cover 2.

[0030] Therefore, when the transmission line needs to be inspected and repaired, the personnel can first rotate the bolt 403 of the first fixing assembly 4, so that the first semicircular tube clamp 402 and the second semicircular tube clamp 401 of the first fixing assembly 4 are no longer fastened to the shaft body 3, but the first semicircular tube clamp 402 and the second semicircular tube clamp 401 still remain connected, so that the first bird-proof cover 1 can be rotated by the personnel around the shaft body 3, and then the first bird-proof cover 1 is located above the second bird-proof cover 2, so that the first bird-proof cover 1 can be carried on the second bird-proof cover 2 under the action of gravity. At this time, the bird-proof cover body cannot completely cover the insulator, which is convenient for personnel to inspect and repair the transmission line. Figure 7 As shown, the problem of increased difficulty in work for personnel due to obstruction caused by bird-proof covers during high-altitude operations is solved, and the problem of having nowhere to put the bird-proof covers when they are temporarily dismantled is also solved. While improving efficiency, it also greatly reduces safety issues caused by the bird-proof covers.

[0031] Among them, Figure 1 , Figure 2 and Figure 3 As shown, the device also includes a shield 5, which is located between the first bird-proof cover 1 and the second bird-proof cover 2. Specifically, baffles 9 are respectively fixed on the sides of the first bird-proof cover 1 and the second bird-proof cover 2 that are arranged opposite to each other. The upper end of the shield 5 is fixed on the baffle 9 of the first bird-proof cover 1, and the lower end of the shield 5 is in contact with the baffle 9 of the second bird-proof cover 2. The shield 5 is a plate made of PVC plastic or epoxy resin and has a certain deformation ability. When the upper and lower parts of the shield 5 are respectively in contact with the baffle 9 of the first bird-proof cover 1 and the baffle 9 of the second bird-proof cover 2 After the baffle plates 9 come into contact, the shield plate 5 will fit tightly with the two baffle plates 9, thereby sealing the gap between the first bird-proof cover 1 and the second bird-proof cover 2, preventing bird droppings from falling onto the insulator through the gap. In addition, since the shield plate 5 is in contact with the baffle plates 9 of the first bird-proof cover 1 and the baffle plates 9 of the second bird-proof cover 2 respectively, it can prevent the first bird-proof cover 1 and the second bird-proof cover 2 from relative rotation when the bird-proof cover body is fixed on the shaft body 3, thereby improving the splicing stability of the first bird-proof cover 1 and the second bird-proof cover 2.

[0032] like Figure 3 and Figure 5 As shown, a card slot 501 is opened at the bottom of the shield plate 5. When the shield plate 5 contacts the baffle 9 of the second bird-proof cover 2, the second semicircular tube card 401 of the second fixing component is located in the card slot 501, thereby avoiding the second fixing component from hindering the position layout of the shield plate 5.

[0033] Among them, Figure 1 and Figure 6 As shown, the tops of the first bird-proof cover 1 and the second bird-proof cover 2 are both provided with strip reinforcement ribs 6, and the bottoms of the first bird-proof cover 1 and the second bird-proof cover 2 are provided with semi-annular reinforcement ribs 8 and triangular reinforcement ribs 7, and the triangular reinforcement ribs 7 penetrate the semi-annular reinforcement ribs 8, thereby improving the strength of the first bird-proof cover 1 and the second bird-proof cover 2 themselves.
