Technical Field
[0001] This invention relates to the field of power transmission line technology, and in particular to a bird droppings prevention device for power transmission line insulators. Background Technology
[0002] With the continuous improvement of the natural environment, bird activity has become more frequent. Insulators on high-voltage transmission lines are often exposed to unprotected natural environments, and birds frequently land on them, resulting in bird droppings covering the insulators. This can easily lead to safety accidents such as flashover, leakage, and short circuits, increasing the risk of tripping due to bird droppings. The work of controlling bird damage to transmission lines is becoming increasingly important. Nowadays, some insulator products are equipped with similar protective covers, but these are composed of two connected cover pieces, requiring two hands to operate simultaneously during installation. Since the insulators are at a high height off the ground, this inevitably increases the risk factor for workers. How to effectively reduce bird droppings falling on cables has become an important task in the management of transmission lines.
[0003] Traditional fiberglass bird covers use two semicircles spliced together. When the power transmission line is repaired or maintained, workers must remove the entire bird cover. Because it is at a high altitude, there is nowhere to put the temporarily removed fiberglass bird cover. This greatly increases the difficulty and danger of the workers' task. Even if there is a place to put it, it may fall to the ground because it is not secured, and it will need to be retrieved. This is time-consuming and laborious, and it may also break directly when it falls to the ground, causing damage to the power company's property. Summary of the Invention
[0004] The main objective of this invention is to provide a bird droppings prevention device for power transmission line insulators. The first bird-proof cover can be mounted on the second bird-proof cover under the action of gravity, which solves the problem of increased work difficulty caused by the obstruction of the bird-proof cover when working at heights. It also solves the problem of having nowhere to put the bird-proof cover when it is temporarily disassembled. While improving efficiency, it also greatly reduces the safety problems caused by the bird-proof cover.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A bird droppings prevention device for transmission line insulators includes a shaft and a bird-proof cover. The bird-proof cover includes a first bird-proof cover and a second bird-proof cover. The first bird-proof cover is connected to the shaft via a first fixing component. The second bird-proof cover is staggered vertically from the first bird-proof cover and is fixed to the shaft. The fixing component is used to prevent the first bird-proof cover from rotating relative to the shaft when tightened.
[0007] Furthermore, the fixing component includes a first semi-circular tube clamp and a second semi-circular tube clamp, which are fixed to the shaft by bolts. The first semi-circular tube clamp and the first bird guard are fixedly connected.
[0008] Furthermore, it also includes a shield located between the first bird shield and the second bird shield to seal the gap between the first bird shield and the second bird shield.
[0009] Furthermore, baffles are fixed to the opposite sides of the first and second bird-proof covers, with the upper end of the baffles fixed to the baffle of the first bird-proof cover and the lower end of the baffles in contact with the baffle of the second bird-proof cover.
[0010] Furthermore, the second bird shield is fixed to the shaft by a fixing assembly, and a slot is provided at the bottom of the shield, in which the second semi-circular tube of the fixing assembly that fixes the second bird shield is located.
[0011] Furthermore, the first and second bird shields have the same structure, and the bird shield body is circular with its center arched upwards.
[0012] Furthermore, both the first and second bird guards are provided with strip-shaped reinforcing ribs at the top.
[0013] Furthermore, the bottom of the first and second bird shields is provided with a semi-circular reinforcing rib and a triangular reinforcing rib, and the triangular reinforcing rib penetrates through the semi-circular reinforcing rib.
[0014] Furthermore, the shield is made of an elastic material.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The first bird cover of the present invention can rotate around the axis when disassembled, so that the first bird cover is above the second bird cover, and thus the first bird cover can be mounted on the second bird cover under the action of gravity. This solves the problem of the increased difficulty of work caused by the obstruction of the bird cover when working at heights, and also solves the problem of where to put the bird cover when it is temporarily disassembled. While improving efficiency, it also greatly reduces the safety problems caused by the bird cover.
[0017] 2. The shield of the present invention can seal the gap between the first bird shield and the second bird shield, thereby preventing bird droppings from falling onto the insulator through this gap.
[0018] 3. The baffles of the present invention are in contact with the baffles of the first bird cover and the second bird cover respectively, so they can prevent the first bird cover and the second bird cover from rotating relative to each other when the bird cover body is fixed on the shaft, thereby improving the splicing stability of the first bird cover and the second bird cover.
[0019] 4. When the first bird cover of the present invention is located above the second bird cover, the baffle will contact the baffle of the second bird cover. Since the position of the second bird cover is fixed, the first bird cover will not be able to rotate due to the baffle, thereby avoiding the situation where the first bird cover rotates itself after being mounted on the second bird cover.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0029] like Figure 1-7As shown, a bird droppings prevention device for transmission line insulators includes a shaft 3 and a bird-proof cover. The bird-proof cover 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 3 through a first fixing component 4. The second bird-proof cover 2 is arranged vertically staggered with the first bird-proof cover 1 and is fixed to the shaft 3. The first fixing component 4 is used to prevent the first bird-proof cover 1 from rotating relative to the shaft 3 when tightened.
[0030] In this embodiment, such as Figure 1 and Figure 2 As shown, the first bird shield 1 and the second bird shield 2 have the same structure. The bird shield body composed of the two is circular with its center arched upwards. The first bird shield 1 and the second bird shield 2 are semi-circular fiberglass bird shields. When installing the bird shield body, first fix the shaft 3 to the insulator, and then fix the first bird shield 1 and the second bird shield 2 to the shaft 3 respectively through the first fixing component 4 and the second fixing component, so that the installation height of the first bird shield 1 is higher than that of the second bird shield 2, and they are installed in a staggered manner. At this time, the first bird shield 1 and the second bird shield 2 cooperate, as... Figure 1 As shown, this can prevent bird droppings from falling onto the insulators, thereby avoiding safety accidents such as insulator flashover, leakage, and short circuits caused by bird droppings covering the insulators.
[0031] 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 semi-circular pipe clamp 402 and a second semi-circular pipe clamp 401. The first semi-circular pipe clamp 402 and the second semi-circular pipe clamp 401 are fixed to the shaft 3 by bolts 403, which are spur bolts. The first semi-circular pipe clamp 402 of the first fixing component 4 is fixedly connected to the first bird cover 1, and the first semi-circular pipe clamp 402 of the second fixing component is fixedly connected to the second bird cover 2.
[0032] Therefore, when maintenance is required on the transmission line, personnel can first rotate the bolts 403 of the first fixing component 4, so that the first semi-circular pipe clamp 402 and the second semi-circular pipe clamp 401 of the first fixing component 4 are no longer fastened to the shaft 3, but the first semi-circular pipe clamp 402 and the second semi-circular pipe clamp 401 remain connected. This allows the first bird cover 1 to be rotated by personnel around the shaft 3, thereby positioning the first bird cover 1 above the second bird cover 2. This allows the first bird cover 1 to be supported on the second bird cover 2 under the influence of gravity. At this time, the bird cover cannot completely cover the insulator, facilitating maintenance of the transmission line. Figure 7 As shown, this invention solves the problem of increased work difficulty caused by bird shields during high-altitude operations, and also solves the problem of nowhere to put bird shields when they are temporarily disassembled. While improving efficiency, it also greatly reduces the safety problems caused by bird shields.
[0033] Among them, such as Figure 1 , Figure 2 and Figure 3 As shown, this device also includes a shield 5, which is located between the first bird shield 1 and the second bird shield 2. Specifically, baffles 9 are fixed to the opposite sides of the first bird shield 1 and the second bird shield 2, respectively. The upper end of the shield 5 is fixed to the baffle 9 of the first bird shield 1, and the lower end of the shield 5 contacts the baffle 9 of the second bird shield 2. The shield 5 is a plate made of PVC plastic or epoxy resin and has a certain deformation capability. When the upper and lower parts of the shield 5 are respectively in contact with the baffle 9 of the first bird shield 1 and the second bird shield 2... After the baffle 9 comes into contact, the shield 5 will tightly adhere to the two baffles 9, thereby sealing the gap between the first bird cover 1 and the second bird cover 2, preventing bird droppings from falling onto the insulator through this gap. Furthermore, since the shield 5 is in contact with the baffles 9 of the first bird cover 1 and the second bird cover 2 respectively, it can prevent the first bird cover 1 and the second bird cover 2 from rotating relative to each other when the bird cover body is fixed on the shaft 3, thereby improving the splicing stability of the first bird cover 1 and the second bird cover 2.
[0034] like Figure 3 and Figure 5 As shown, a slot 501 is provided at the bottom of the cover plate 5. When the cover plate 5 contacts the baffle 9 of the second bird cover 2, the second semi-circular tube clip 401 of the second fixing component is located in the slot 501, thereby avoiding the second fixing component from obstructing the position of the cover plate 5.
[0035] Among them, such as Figure 1 and Figure 6 As shown, the top of the first bird shield 1 and the second bird shield 2 are provided with strip-shaped reinforcing ribs 6, and the bottom of the first bird shield 1 and the second bird shield 2 are provided with semi-circular reinforcing ribs 8 and triangular reinforcing ribs 7. The triangular reinforcing ribs 7 penetrate the semi-circular reinforcing ribs 8, thereby improving the strength of the first bird shield 1 and the second bird shield 2 themselves.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
