Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrified railway application technology, and in particular to a multi-functional bird cover for electrified railways. Background Technology
[0002] With the continuous expansion of electrified railway networks, the safety and reliability of overhead lines have become crucial factors in ensuring the efficient operation of railway systems. In particular, insulator strings installed along railway lines serve to isolate current and ensure the safety of power transmission. However, these critical components face various threats from the natural environment, one of which is bird activity. In practice, bird nests are frequently found at the junctions between overhead line supports and insulator strings. Because birds frequently move from their nests to the insulator string skirts, where they perch or move about, a large amount of bird droppings accumulates on these skirts. Bird droppings contain conductive substances that can significantly reduce the insulation performance of the insulator strings, thereby increasing the risk of short circuits in the power system and, in severe cases, potentially causing power outages and disrupting the normal operation of the railway system. Summary of the Invention
[0003] This utility model addresses the problems of existing technologies by providing a multifunctional bird shield for electrified railways. Its novel structure reduces the frequency of birds moving or perching on the skirts of insulator strings, decreases the amount of bird droppings on the skirts, reduces the impact of bird droppings on the insulation performance of the insulator strings, improves the reliability and safety of overhead lines on electrified railways, provides some shielding, and reduces external corrosion, thus giving this utility model a multifunctional effect.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model provides a multi-functional bird cover for electrified railways, which includes a first mounting sleeve and a second mounting sleeve arranged opposite each other. The first mounting sleeve and the second mounting sleeve are detachably connected to each other on one side. Both the first mounting sleeve and the second mounting sleeve are hollow, and a mounting cavity is formed between the first mounting sleeve and the second mounting sleeve. One end of the first mounting sleeve extends forward and is provided with an arc-shaped cover.
[0006] The first mounting sleeve has a first arc-shaped connecting plate on the side near the second mounting sleeve, and the second mounting sleeve has a second arc-shaped connecting plate on the side near the first mounting sleeve. The first arc-shaped connecting plate and the second arc-shaped connecting plate are directly opposite each other and are detachably connected.
[0007] The first arc-shaped connecting plate and the second arc-shaped connecting plate are respectively provided with a first connecting ear and a second connecting ear. The first connecting ear is provided with a first connecting hole, and the second connecting ear is provided with a second connecting hole. The first connecting hole and the second connecting hole are provided correspondingly, and a first locking component is connected between the first connecting hole and the second connecting hole.
[0008] The first locking assembly includes a first screw and a first nut. The first screw includes a first nut and a first screw rod. The first screw rod passes through the first connecting hole and the second connecting hole in sequence and is threadedly connected to the first nut.
[0009] The first mounting sleeve has a first semi-circular extension plate extending from its outer side wall, and the second mounting sleeve has a second semi-circular extension plate extending from its outer side wall. The first semi-circular extension plate and the second semi-circular extension plate abut against each other at their respective end faces to form a circular plate. The first semi-circular extension plate and the second semi-circular extension plate are detachably connected.
[0010] The first semicircular extension plate has a third connecting ear at each end of its inner sidewall, and the second semicircular extension plate has a fourth connecting ear at each end of its inner sidewall. The third connecting ear is provided with a third connecting hole, and the fourth connecting ear is provided with a fourth connecting hole. The third connecting hole and the fourth connecting hole are provided correspondingly, and a second locking component is connected between the third connecting hole and the fourth connecting hole.
[0011] The second locking assembly includes a second screw and a second nut. The second screw includes a second nut and a second screw rod. The second screw rod passes through the third connecting hole and the fourth connecting hole in sequence and is threadedly connected to the second nut.
[0012] The arc-shaped cover is vertically arranged on the first semi-circular extension plate, and multiple reinforcing ribs are provided between the arc-shaped cover and the first semi-circular extension plate.
[0013] The first semi-circular extension plate, the arc-shaped cover, and the reinforcing rib are integrally formed.
[0014] The beneficial effects of this utility model are:
[0015] This utility model features a novel structure and ingenious design. In use, it is applied to overhead lines on electrified railways. Before installation, the first and second mounting sleeves are disassembled, and then the utility model is installed on the insulator strings of the overhead line. During installation, the first and second mounting sleeves are placed on either side of the insulator string, and then fitted onto both sides of the insulator string, so that the first and second mounting sleeves abut against each other to form a mounting cavity that covers the insulator string. The first and second mounting sleeves are then connected. Furthermore, the first mounting sleeve is positioned above the second mounting sleeve, i.e., the arc-shaped cover is positioned above. Preferably, this utility model is installed at the connection point between the overhead line support and the insulator string, which can prevent birds from entering from the overhead line. The nests at the connection point between the line support and the insulator string are moved to the skirts of the insulator string, thereby reducing the frequency of birds moving or perching on the skirts. Since birds are less frequently seen on the skirts, bird droppings are less likely to accumulate, reducing the amount of bird droppings and thus lessening their impact on the insulation performance of the insulator string. This improves the reliability and safety of overhead lines on electrified railways. Simultaneously, because one end of the first mounting sleeve extends forward with the arc-shaped cover, and the arc-shaped cover is located on top, this embodiment of the application also provides a certain degree of shielding. Furthermore, the arc-shaped cover can also guide rainwater, reducing damage to the connection point between the overhead line support and the insulator string caused by prolonged exposure to sunlight or rainwater, and reducing external corrosion. Therefore, this embodiment of the application achieves a multi-functional effect. Attached Figure Description

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.
[0023] A multi-functional bird cover for electrified railways, such as Figures 1 to 4As shown, it includes a first mounting sleeve 1 and a second mounting sleeve 2 arranged opposite each other. The first mounting sleeve 1 and the second mounting sleeve 2 are detachably connected to each other on one side. Both the first mounting sleeve 1 and the second mounting sleeve 2 are hollow. An mounting cavity is formed between the first mounting sleeve 1 and the second mounting sleeve 2. One end of the first mounting sleeve 1 extends forward and is provided with an arc-shaped cover 3. Specifically, this utility model has a novel structure and ingenious design. In use, this embodiment is applied to overhead lines on electrified railways. Before installation, the first mounting sleeve 1 and the second mounting sleeve 2 are first disassembled, and then this embodiment is installed on the insulator string of the overhead line. During installation, the first mounting sleeve 1 and the second mounting sleeve 2 are respectively placed on both sides of the insulator string of the overhead line, and the first mounting sleeve 1 and the second mounting sleeve 2 are respectively fitted onto both sides of the insulator string of the overhead line, so that the first mounting sleeve 1 and the second mounting sleeve 2 abut against each other to form a mounting cavity that covers the insulator string. Then the first mounting sleeve 1 and the second mounting sleeve 2 are connected together. Further, the first mounting sleeve 1 is located above the second mounting sleeve 2, that is, the arc-shaped cover 3 is located above. Preferably, this embodiment is installed at the connection point between the overhead line support and the insulator string. This design prevents birds from moving from their nests at the connection point between the overhead line support and the insulator string to the insulator string's skirts, thereby reducing the frequency of birds moving or perching on the skirts. Since birds are less frequently seen on the skirts, bird droppings are less likely to accumulate, reducing the amount of droppings and thus lessening their impact on the insulation performance of the insulator string. This improves the reliability and safety of overhead lines on electrified railways. Simultaneously, because one end of the first mounting sleeve 1 extends forward with the arc-shaped cover 3 positioned above, this embodiment also provides some shielding. Furthermore, the arc-shaped cover 3 also acts as a rainwater guide, reducing damage to the connection point between the overhead line support and the insulator string from prolonged exposure to sunlight or rain, and minimizing external corrosion. Therefore, this embodiment offers multiple benefits.
[0024] In this embodiment, a first arc-shaped connecting plate 4 is provided on the side of the first mounting sleeve 1 near the second mounting sleeve 2, and a second arc-shaped connecting plate 5 is provided on the side of the second mounting sleeve 2 near the first mounting sleeve 1. The first arc-shaped connecting plate 4 and the second arc-shaped connecting plate 5 are directly opposite each other and are detachably connected. A first connecting lug 6 and a second connecting lug 7 are respectively provided at both ends of the first arc-shaped connecting plate 4 and the second arc-shaped connecting plate 5. A first connecting lug 6 is provided through a first connecting hole 8, and a second connecting lug 7 is provided through a second connecting hole 9. The first connecting hole 8 and the second connecting hole 9 are correspondingly provided, and a first locking assembly 10 is connected between the first connecting hole 8 and the second connecting hole 9. The first locking assembly 10 includes a first screw 11 and a first nut 12. The first screw 11 includes a first nut and a first screw rod. The first screw rod passes through the first connecting hole 8 and the second connecting hole 9 in sequence and is threadedly connected to the first nut 12. Specifically, when the first mounting sleeve 1 and the second mounting sleeve 2 are assembled and connected, they are locked and fixed by the first locking assembly 10. In use, the first mounting sleeve 1 and the second mounting sleeve 2 are respectively fitted onto both sides of the insulator string of the overhead line, so that the first mounting sleeve 1 and the second mounting sleeve 2 abut against each other to form a mounting cavity that covers the insulator string. Then, they are connected between the first connecting hole 8 and the second connecting hole 9 by the first locking assembly 10. The first screw 11 passes through the second connecting hole 9 and the first connecting hole 8 and is threadedly connected to the first nut 12. The first nut 12 abuts against the first connecting lug 6, and the first nut abuts against the second connecting lug 7. After connection, the first nut 12 is tightened so that the first connecting lug 6 and the second connecting lug 7 cooperate to abut against each other. The first mounting sleeve 1 and the second mounting sleeve 2 cooperate to lock the insulator string on the overhead line.
[0025] In this embodiment, a first semi-circular extension plate 13 extends from the outer wall of the first mounting sleeve 1, and a second semi-circular extension plate 14 extends from the outer wall of the second mounting sleeve 2. The end faces of the first semi-circular extension plate 13 and the second semi-circular extension plate 14 abut against each other to form a circular plate. The first semi-circular extension plate 13 and the second semi-circular extension plate 14 are detachably connected. Third connecting ears 15 are respectively provided at both ends of the inner sidewall of the first semi-circular extension plate 13, and fourth connecting ears 14 are respectively provided at both ends of the inner sidewall of the second semi-circular extension plate 14. 6. The third connecting ear 15 is provided with a third connecting hole 17, and the fourth connecting ear 16 is provided with a fourth connecting hole 18. The third connecting hole 17 and the fourth connecting hole 18 are provided correspondingly. A second locking component 19 is connected between the third connecting hole 17 and the fourth connecting hole 18. The second locking component 19 includes a second screw 20 and a second nut 21. The second screw 20 includes a second nut and a second screw rod. The second screw rod passes through the third connecting hole 17 and the fourth connecting hole 18 in sequence and is threadedly connected to the second nut 21. Specifically, after the first mounting sleeve 1 and the second mounting sleeve 2 are connected, the first semi-circular extension plate 13 and the second semi-circular extension plate 14 abut against each other, so that the third connecting ear 15 and the fourth connecting ear 16 abut together. The second locking component 19 is connected between the third connecting hole 17 and the fourth connecting hole 18. The connection method of the second locking component 19 is basically the same as that of the first locking component 10, that is, the second screw passes through the third connecting hole 17 and the fourth connecting hole 18 and is screwed into the second nut 21.
[0026] In this embodiment, the arc-shaped cover 3 is vertically disposed on the first semi-circular extension plate 13, and a plurality of reinforcing ribs 22 are provided between the arc-shaped cover 3 and the first semi-circular extension plate 13. Specifically, the reinforcing ribs 22 improve the connection stability and connection strength between the arc-shaped cover 3 and the first semi-circular extension plate 13.
[0027] In this embodiment, the first semi-circular extension plate 13, the arc-shaped cover 3, and the reinforcing rib 22 are integrally formed. Specifically, this configuration improves structural strength and stability.
