Description

Technical Field

[0001] This utility model relates to the field of power transmission protection, specifically to a composite insulating bird-proof cover. Background Technology

[0002] Bird-related tripping faults account for about one-third of all tripping faults in overhead transmission lines. These faults are mainly caused by bird droppings short-circuiting the air gap at the insulator, with a small number caused by short-circuiting of bird nest materials. Installing bird guards on the insulators is the most economical and practical solution to prevent bird droppings and other bird-related damage.

[0003] Currently, bird shields are mostly made of two semi-circular covers that are joined together and fixed to the hardware position on the upper end of the insulator. After joining, the central hole is used to tightly fit the hardware for a secure fit. Although bird shields achieve the purpose of preventing bird-related faults such as short circuits caused by bird droppings, they are very susceptible to swaying due to their large stress area and high altitude position, especially during strong winds. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a composite insulating bird cover with a simple structure that is less prone to shaking due to wind and has a more secure installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A composite insulating bird shield includes a main body of the bird shield, which is composed of two symmetrically arranged semi-circular combined shields, which are spliced ​​together to form a complete circular main body.

[0007] The top of the main body is provided with a folding component. One end of the folding component is hinged to the main body. The free end of the folding component is connected to an arc-shaped connecting block. At least two anti-loosening nuts are threadedly installed on the hinge axis of the folding component, the main body, and the arc-shaped connecting block. After the folding component is unfolded, several arc-shaped connecting blocks form a connecting ring. The connecting ring is fixed to the outside of the hardware on the upper part of the insulator by a clamping member.

[0008] A design for a folding assembly, wherein the folding assembly is hinged end to end by at least two connecting plates.

[0009] To reduce the risk of birds approaching the insulator, several slots are cut into the surface of the connecting plate, through which blades are connected by rotating shafts; binding shafts are provided on both sides of the blades, and each binding shaft is tied with a ribbon that flutters in the wind.

[0010] To facilitate the storage of the folding components, the folding components are connected end to end by at least two connecting plates. The top of the main body has evenly distributed annular grooves, and the folding components are placed in the grooves.

[0011] To enhance the reinforcement and secure installation of the folding component onto the main body, one end of the folding component is connected to the groove near the outer side of the main body.

[0012] To improve the overall strength of the combined cover, a semi-circular snap-fit ​​groove is opened on the side of the combined cover splicing, and an upwardly extending integral connecting body is provided on the top of the side of the combined cover splicing. The two connecting bodies are connected by a connecting structure.

[0013] To improve the splicing connection of the combined covers, the connection structure includes several connection holes on the connecting body. When two combined covers are spliced ​​into a complete body, the two combined covers are connected together by bolts and nuts passing through the connection holes.

[0014] In summary, when using this device, firstly, the two semi-circular snap-fit ​​slots are snapped onto the hardware on the upper part of the insulator. The two combined covers are then connected together by bolts and nuts passing through the connecting holes, achieving the initial connection between the bird cover and the hardware. Next, the folding assembly is unfolded, and the concave surface of the arc-shaped connecting block is placed against the side of the hardware. Several arc-shaped connecting blocks form a connecting ring. The outer ring of the connecting ring is tightened by straps or clamps to fix the connecting ring to the hardware. Finally, the position of the anti-loosening nut is adjusted, and the anti-loosening nut is used to tighten the hinge shaft to lock the folding assembly at all hinge points, thereby further strengthening the installation of the bird cover. Finally, by tightening the folding assembly, the device can be guaranteed to withstand greater winds. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See attached document Figure 1-7 This utility model is a composite insulating bird cover, including the bird cover body.

[0026] Example 1, refer to Appendix Figure 1 The main body consists of two symmetrically arranged semi-circular combination covers 1. The two semi-circular combination covers 1 are spliced ​​together to form a complete circular main body. Semi-circular snap-fit ​​grooves are opened on the splicing side of the combination covers 1. The top of the splicing side of the combination covers 1 is provided with an upwardly extending integrally formed connector 2. Several connection holes 3 are opened on the connector 2. The top of one of the connector 2s extends towards the side of the mating connector to form a buckle plate 9. The top of the combination covers all form a reinforcing rib along the radial upward direction. When the two combination covers are spliced ​​together to form a complete main body, the two semi-circular snap-fit ​​grooves are snapped onto the hardware 4 on the upper part of the insulator. The connection holes on the two connectors 2 are aligned. The two combination covers are connected together by bolts and nuts passing through the connection holes, realizing the initial connection between the bird cover and the hardware.

[0027] Example 2, refer to Appendix Figure 2-5 The top of the main body has evenly distributed annular grooves, each containing a folding component. One end of the folding component is hinged to the bottom of the groove, and the free end of the folding component is hinged to an arc-shaped connecting block 5. Four anti-loosening nuts 10 are threaded onto the hinge axis connecting the folding component, the main body, and the arc-shaped connecting block 5. These four anti-loosening nuts 10 abut against each other in pairs to prevent the folding component from moving as a whole. When the folding component is unfolded, the concave surface of the arc-shaped connecting block is placed against the side of the hardware. Several arc-shaped connecting blocks 5 form a connecting ring. The outer ring of the connecting ring is fixed to the hardware by a clamping device. Figure 6As shown, the unfolded folding assembly, hardware, and combined cover form a triangular structure. The folding assembly is in a taut state, making the connection between the body and the hardware more stable. The groove also improves the overall torsional strength of the body.

[0028] See attached document Figure 3-7 The folding assembly is connected end to end by four connecting plates 8. One end of the folding assembly is connected to the groove near the outer side of the main body. Several through slots 6 are opened on the surface of the connecting plates. The blades 7 are rotatably connected in the through slots 6 by shafts. The blades 7 can be completely hidden in the corresponding through slots 6. Binding shafts 11 are provided on both sides of the blades 7. Each binding shaft 11 is bound with a ribbon 12 that flutters in the wind. When this device is installed on the upper side of the insulator, the blades 7 can rotate under the action of the wind, thereby increasing the swing amplitude of the ribbons 12, which can scare away birds and reduce birds from approaching the insulator.

[0029] See attached document Figure 7 When using this device, firstly, the two semi-circular snap-fit ​​slots are snapped onto the hardware 4 on the upper part of the insulator. Then, the two combined covers 1 are connected together by bolts and nuts passing through the connecting holes, achieving the initial connection between the bird cover and the hardware. Next, the folding assembly is unfolded, and the concave surface of the arc-shaped connecting block 5 is attached to the side of the hardware. Several arc-shaped connecting blocks form a connecting ring. The outer ring of the connecting ring is tightened by straps or clamps, thus fixing the connecting ring to the hardware. Finally, the position of the anti-loosening nut 10 is adjusted, and the anti-loosening nut 10 is used to tighten the hinge shaft to lock the folding assembly at all hinge points, thereby further strengthening the installation of the bird cover. Finally, by tightening the folding assembly, the device can be guaranteed to withstand greater winds.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
