Description

Technical Field

[0001] This utility model relates to the field of power transmission line protection technology, and in particular to a power transmission line protection device. Background Technology

[0002] In power transmission systems, wild animals climbing poles or conductors can cause short circuits, equipment damage, or even large-scale power outages. To prevent such accidents, the power industry commonly uses metal anti-climb spikes as protective devices. These spikes prevent animals from contacting the conductors through their sharp physical structure and have advantages such as low cost and easy installation.

[0003] Referring to the case "A Rotary Protective Device for Transmission Lines" (Publication No. CN217720654U), this utility model discloses a rotary protective device for transmission lines, belonging to the field of transmission line protection. It includes a spike wheel body, with an upright placement frame fitted at each end of the spike wheel body, and an anti-contact baffle between the upright placement frames. This utility model's rotary protective device for transmission lines, through the upright placement frames, allows the rotating spike wheel to be placed upright. The closed upright placement frames increase the upright support area of ​​the spike wheel body, improving the difficulty of placing the rotating spike wheel. The anti-contact baffles surround the spike components, reducing the risk of the spike components touching the ground after the rotating spike wheel tilts when placed upright. Furthermore, during installation, it prevents contact with the spike components, reducing the risk of injury to operators who touch the spike components while installing the rotating spike wheel at height.

[0004] While the aforementioned device can prevent animals from climbing, it still has the following drawbacks: some small animals, such as squirrels, can use the gaps between the spikes to bypass the protected area, and snakes can use their flexible bodies to wrap around the spikes to climb up. Therefore, the protective effect is limited, and using sharp structures as protective structures may also cause harm to animals. Utility Model Content

[0005] Therefore, it is necessary to provide a power transmission line protection device to address the problem that the above-mentioned power transmission line protection devices have limited protective effects and are also prone to causing harm to animals.

[0006] A protective device for power transmission lines includes: a sleeve fitted onto the end of the transmission line;

[0007] Protective component, wherein the protective component is disposed on the surface of the sleeve;

[0008] The protective components include a guide plate disposed on the surface of the sleeve.

[0009] In one embodiment, multiple guide plates are arranged in a rectangular array, with the size of the multiple guide plates gradually increasing from the inside to the outside.

[0010] In one embodiment, the protective assembly further includes a groove formed on the surface of the sleeve, in which a slide block is slidably connected, and the slide block is fixedly connected to the side of the guide plate near the sleeve.

[0011] In one embodiment, magnetic blocks are provided on the front and rear sides of the two guide plates on opposite sides, and the two magnetic blocks attract each other.

[0012] In one embodiment, perforations are formed on the surface of multiple guide plates, and insert rods are inserted between the perforations on the surfaces of multiple guide plates. The insert rods are J-shaped, and slots are formed at both ends of the sleeve. The bent end of the insert rod is inserted into the slot, and a nut is threaded onto the other end of the insert rod.

[0013] In one embodiment, a locking element is provided between the surfaces of the two bushings, the locking element being used to close the two bushings and position them on the surface of the transmission line.

[0014] In one embodiment, the inner walls of both sleeves are bonded with an insulating layer. Beneficial effects

[0015] 1. The guide plate in the protective component gradually expands from the inside to the outside, which can not only block the animal from the end, but also form a dynamic sliding surface when rotating, so that snakes cannot be wrapped and fixed. Moreover, when animals such as squirrels come into contact with the guide plate, the guide plate will rotate in the sliding groove through the sliding seat, which can make the animal unstable and fall off, thus improving the protection effect for the animal.

[0016] 2. By setting magnetic blocks, the connection effect between the guide plates can be ensured when personnel connect two sets of protective components. At the same time, by using the plug rod, the stability of multiple guide plates on the bushing surface can be ensured when personnel place the protective components on the surface of the transmission line, providing convenience for personnel installation work.

[0029] The following is combined Figures 1-4 This invention describes a power transmission line protection device.

[0030] In one embodiment, a power transmission line protection device includes: a sleeve 1 fitted onto the end of the transmission line;

[0031] Protective component 2 is disposed on the surface of sleeve 1;

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the protective component 2 includes a guide plate 201 disposed on the surface of the sleeve 1; multiple guide plates 201 are arranged in a rectangular array, and the size of the multiple guide plates 201 gradually increases from the inside to the outside.

[0033] When an animal crawls to the end of the power transmission line, because there are multiple guide plates 201 and the multiple guide plates 201 are composed of a flat X-shaped design at the view angle, the guide plate 201 with a larger side can block the animal. At the same time, the guide plate 201 is circular in design. When the animal comes into contact with the guide plate 201, the arc-shaped part of the side of the guide plate 201 cannot provide support for the animal, which will cause the animal to lose stability and slip.

[0034] The protective component 2 also includes a groove 203 formed on the surface of the sleeve 1, and a slide block 202 is slidably connected in the groove 203. The slide block 202 is fixedly connected to the side of the guide plate 201 near the sleeve 1.

[0035] When an animal comes into contact with the guide plate 201, one side of the guide plate 201 is subjected to force, and then it will rotate in the slide groove 203 through the slide block 202. At this time, the animal will lose its support point on the surface of the guide plate 201 and slide off the surface of the guide plate 201.

[0036] Since snakes need static fixed points to climb, and small animals like squirrels will rotate when they come into contact with the guide plate 201, and birds use the power transmission line as a perch, the guide plate 201 cannot provide effective support for them. Therefore, the guide plate 201 is designed to be rotatable, which can prevent various animals from climbing and thus provide effective protection for the power transmission line.

[0037] Two guide plates 201 are provided with magnetic blocks 205 on the front and rear sides of opposite sides, and the two magnetic blocks 205 attract each other; multiple guide plates 201 have perforations on their surfaces, and insert rods 204 are inserted between the perforations on the surfaces of multiple guide plates 201. The insert rods 204 are J-shaped, and slots are provided at both ends of the sleeve 1. The bent end of the insert rod 204 is inserted into the slot, and a nut is threaded onto the other end of the insert rod 204.

[0038] When personnel need to install the entire device on the end surface of the transmission line, the staff first aligns the directions of the multiple guide plates 201, then inserts the rod 204 between the multiple guide plates 201. At this time, the multiple guide plates 201 will be limited by the rod 204. Then, the bent end of the rod 204 is inserted into the slot at the end of the sleeve 1, and the angle of the multiple guide plates 201 will be locked.

[0039] Then the staff put the two sleeves 1 on the surface of the transmission line, one above the other. At this time, the magnetic blocks 205 of the two sets of guide plates 201 will connect with each other, which can achieve the effect of auxiliary positioning.

[0040] A locking element 3 is provided between the surfaces of the two bushings 1. The locking element 3 is used to close the two bushings 1 and position them on the surface of the power transmission line.

[0041] Then the staff will put the locking piece 3 on the middle of the surface of the two sleeves 1 and lock it. At this time, the two sleeves 1 will form a complete pipe and be put on the surface of the power transmission line. Thus, the protective component 2 is installed.

[0042] It should be noted that the locking component 3 consists of two connecting sleeves. One of the connecting points of the two connecting sleeves is movably connected by a rotating shaft. The other connecting point of the two connecting sleeves is provided with a through hole. A bolt is inserted between the through holes of the two connecting sleeves. A nut is threaded onto the surface of the bolt. When connecting the two sleeves 1, first place the two connecting sleeves on the surface of the two sleeves 1 respectively, then insert the bolt between the two through holes, and then screw the nut onto the surface of the bolt until the nut abuts against one of the connecting sleeves, thus completing the locking operation of the two sleeves 1.

[0043] The inner walls of both sleeves 1 are bonded with an insulating layer 4;

[0044] An insulating layer 4 is provided inside the sleeve 1. When an animal touches the sleeve 1 and the adjacent wire at the same time, the insulating layer 4 can block the current path. At the same time, the insulating layer 4 can withstand the impact of a short circuit current of >100kA, which can prevent it from being burned by electric arc and improve the service life of the sleeve 1.

[0045] It should be noted that the above-mentioned overall device is installed horizontally at the end of the power transmission line. By setting the protective device at the end of the power transmission line, animals can be guided away from the end when they climb up the utility pole or surrounding trees to the vicinity of the power transmission line.

[0046] Working principle: When an animal crawls to the end of the power transmission line, multiple guide plates 201 are provided. The larger guide plates 201 can block the animal. At the same time, the guide plates 201 are circular in design. When an animal comes into contact with the guide plate 201, the curved part of the guide plate 201 cannot provide support for the animal, causing the animal to lose stability and slip. Since snakes need a static fixed point to climb, and small animals such as squirrels will rotate when they come into contact with the guide plate 201, and birds use the power transmission line as a perch, the guide plate 201 cannot provide effective support for them. Therefore, the guide plate 201 is designed to be rotatable, which can prevent various animals from climbing and thus provide effective protection for the power transmission line.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
