Description

Technical Field

[0001] This utility model relates to the technical field of bird-proof protective covers, and in particular to a bird-proof insulating protective cover for power distribution lines that can be installed quickly. Background Technology

[0002] Currently, birds are frequently active on power distribution lines, often perching or nesting near pole crossarms, insulators, and conductors. When birds land on poles and build nests, they not only bring twigs, weeds, and other foreign objects that fall onto the conductors, but also leave droppings on insulators and metal components. These foreign objects and contaminants can easily degrade the surface insulation performance of insulators, leading to discharges, flashovers, short circuits, and grounding accidents. In severe cases, this can cause power outages or even damage to electrical equipment, posing a significant threat to the safe and stable operation of the power system. Therefore, power departments generally install bird-proof devices to prevent birds from perching and nesting on power equipment. These protective covers are typically made of weather-resistant insulating materials such as modified engineering plastics, possessing properties such as high-temperature resistance, low-temperature resistance, UV aging resistance, and corrosion resistance. However, there are significant shortcomings in their installation.

[0003] Existing bird guards for power distribution lines generally require bolt fasteners for reinforcement during installation. While this ensures stability to some extent, the installation process is cumbersome, especially when working at heights on utility poles. Workers must carry multiple tools and tighten each bolt individually, resulting in numerous steps, time-consuming operations, increased labor intensity and safety risks at heights, and the need to repeat the same tedious fixing steps during later maintenance or replacement. This severely impacts construction efficiency and maintenance convenience. Therefore, existing bird guards still have significant shortcomings in terms of ease of installation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a bird-proof insulating protective cover for power distribution lines that can be installed quickly, so as to solve the problem that when installing the existing protective cover, the construction personnel need to carry a variety of tools and tighten the bolts one by one, which not only involves many operation steps and is time-consuming, but also increases the labor intensity and safety risks of working at height.

[0005] To achieve the above objectives, this utility model provides a bird-proof insulating protective cover for power distribution lines that can be installed quickly. It includes a support column, with a crossarm for supporting insulators fixedly connected to the top of the support column. A first protective cover and a second protective cover are respectively placed on the top of the crossarm near the support column to prevent birds from standing on the top of the crossarm. The first and second protective covers are triangular in shape. A fixing mechanism for fixing the first and second protective covers to the top of the crossarm is provided at the bottom of each cover. Connecting holes are provided on both sides of the outer walls of the first and second protective covers. A bird-repelling mechanism is provided on the inner sidewalls of the first and second protective covers near the connecting holes.

[0006] Preferably, the fixing mechanism includes a threaded rod rotatably connected to the inner walls of the first and second protective covers. A rotating handle for the user to drive the threaded rod to rotate is fixedly connected to the outer wall of the threaded rod. A threaded sleeve is threaded onto the outer wall of the threaded rod. A fastener is fixedly connected to the outer wall of the threaded sleeve. The fastener is U-shaped. Guide blocks are fixedly connected to both sides of the first and second protective covers respectively. The two ends of the fastener pass through the top of the guide blocks respectively.

[0007] Preferably, the first protective cover and the second protective cover are both fixedly connected to the opposite surfaces of the fixed plate. The outer wall of the fixed plate on the side wall of the first protective cover is provided with a slot. The outer wall of the fixed plate on the side wall of the second protective cover is fixedly connected to a plug. The plug passes through the slot. The top of the plug is provided with a sliding groove. A spring is fixedly connected inside the sliding groove. A limit block is fixedly connected to the top of the spring. The limit block is slidably connected inside the sliding groove.

[0008] Preferably, the bird-repelling mechanism includes a reflector for reflecting light and repelling birds rotatably connected to the inner sidewall of the first and second protective covers near the connecting hole, and the outer sidewall of the first and second protective covers near the connecting hole is provided with a wind guide groove for guiding the wind to the reflector.

[0009] Preferably, a transparent cover is fixedly connected between the inner walls of the connecting holes, and the transparent cover allows light to pass through and shine onto the reflector.

[0010] Preferably, the side wall of the limiting block is provided with an inclined surface. When the sliding groove drives the limiting block to move upward by its own elasticity, the top of the limiting block extends out of the interior of the sliding groove and fits against the outer wall of the side wall fixing plate of the first protective cover.

[0011] Preferably, ventilation openings for ventilation are provided on the opposite sides of both the first and second protective covers.

[0012] Preferably, both the first and second protective covers have wrapping grooves on their opposite surfaces. When the opposite surfaces of the first and second protective covers are fitted together, the wrapping grooves on the first and second protective covers will wrap around the outer wall of the support column.

[0013] The beneficial effects of this utility model are:

[0014] 1. A quick-installable bird-proof insulating cover for power distribution lines. This insulating cover, through the cooperation of threaded rods, threaded sleeves, and fasteners, allows the cover to be quickly clamped to the bottom of the crossarm. Simultaneously, a fixing plate, inserts, slides, springs, and limit blocks achieve automatic positioning and locking between two protective covers. Compared to existing installation methods that require tightening numerous bolts one by one, this significantly simplifies the operation steps, improves installation efficiency during high-altitude work, reduces the labor intensity and safety risks for construction workers, and ensures the stability and reliability of the installed structure. This effectively overcomes the problems of cumbersome installation, low efficiency, and inconvenient maintenance in the prior art.

[0015] 2. This is a quick-installable bird-proof insulating protective cover for power distribution lines. The bird-repelling mechanism of the cover uses wind guide channels to guide the wind to drive the reflector to rotate, and the transparent cover allows external light to shine through, forming a flashing reflected light, thereby stimulating and repelling birds. Compared with existing bird-proofing methods that simply rely on structural barriers, this not only actively forces birds away from the top of the crossarm, effectively preventing birds from staying, nesting, and their excrement from polluting the insulators and lines, but also achieves long-term stable operation of passive bird repellency relying on natural wind and sunlight, making it easy to use.

[0026] like Figures 1 to 5 As shown, a bird-proof insulating protective cover for power distribution lines that can be installed quickly includes a support column 1. A crossarm 2 for supporting insulators is fixedly connected to the top of the support column 1. A first protective cover 3 and a second protective cover 4 for preventing birds from standing on the top of the crossarm 2 are respectively placed on the top of the crossarm 2 near the support column 1. The first protective cover 3 and the second protective cover 4 are triangular in shape. The bottom of the first protective cover 3 and the second protective cover 4 are provided with a fixing mechanism for fixing the first protective cover 3 and the second protective cover 4 to the top of the crossarm 2. The outer walls of the first protective cover 3 and the second protective cover 4 are provided with connecting holes 16 on both sides. The inner side walls of the first protective cover 3 and the second protective cover 4 near the connecting holes 16 are provided with a bird-repelling mechanism.

[0027] Further, see attached document. Figure 4 and Figure 5As shown, the fixing mechanism includes a threaded rod 5 rotatably connected to the inner walls of the first protective cover 3 and the second protective cover 4. A rotating handle 6 for the user to drive the threaded rod 5 to rotate is fixedly connected to the outer wall of the threaded rod 5. A threaded sleeve 7 is threadedly fitted onto the outer wall of the threaded rod 5. A fastener 8 is fixedly connected to the outer wall of the threaded sleeve 7. The fastener 8 is U-shaped. Guide blocks 9 are fixedly connected to both sides of the first protective cover 3 and the second protective cover 4 respectively. The two ends of the fastener 8 pass through the top of the guide blocks 9 respectively. Fixing plates 10 are fixedly connected to the opposite sides of the first protective cover 3 and the second protective cover 4. A slot 11 is opened on the outer wall of the fixing plate 10 on the side wall of the first protective cover 3. An insert 12 is fixedly connected to the outer wall of the fixing plate 10 on the side wall of the second protective cover 4. The insert 12 passes through the slot 11. A sliding groove 13 is opened on the top of the insert 12. A spring 14 is fixedly connected inside the sliding groove 13. A limit block 15 is fixedly connected to the top of the spring 14. The limit block 15 is slidably connected inside the sliding groove 13.

[0028] During the installation process, the first protective cover 3 and the second protective cover 4 are placed on top of the crossbeam 2, and the fastener 8 is fitted onto the outer wall of the threaded rod 5. The threaded rod 5 is rotatably connected to the inner wall of the protective cover. The user drives the threaded rod 5 to rotate by rotating the handle 6. The outer wall of the threaded rod 5 is threaded with a threaded sleeve 7. When the threaded rod 5 rotates, the threaded sleeve 7 drives the fastener 8, which is fixedly connected, to move upward along the guide block 9, thereby gradually clamping the fastener 8 onto the bottom of the crossbeam 2, achieving a stable fixation of the protective cover. At the same time, when the first protective cover 3 and the second protective cover 4 are installed, they are used in conjunction with the fixing plate 10. The insert 12 passes through the slot 11 and is pushed by the spring 14 inside the slide groove 13, causing the top of the limiting block 15 to extend out of the slide groove 13 and fit against the outer wall of the fixing plate 10. This achieves mutual positioning and limiting locking between the two protective covers. Through the above steps, not only is the speed and reliability of the fixing process guaranteed, but the tedious operation of tightening a large number of bolts one by one is also avoided, greatly improving the efficiency and safety of high-altitude installation.

[0029] Further, see attached document. Figure 3 and Figure 4 As shown, the bird-repelling mechanism includes a reflector 17 for reflecting light and repelling birds, which is rotatably connected to the inner side wall of the first protective cover 3 and the second protective cover 4 near the connecting hole 16. The outer side wall of the first protective cover 3 and the second protective cover 4 near the connecting hole 16 is provided with a wind guide groove 18 for guiding the wind to blow towards the reflector 17. A transparent cover 19 is fixedly connected between the inner walls of the connecting hole 16. The transparent cover 19 allows light to pass through the transparent cover 19 and shine onto the reflector 17.

[0030] During the bird-proofing process of the protective cover, the bird-repelling mechanism can actively enhance the bird-proofing effect. Specifically, the inner walls of the first protective cover 3 and the second protective cover 4 are rotatably connected to reflectors 17 near the connecting hole 16. When the outside wind blows in through the air guide 18, the airflow is guided to the connecting hole 16 and acts on the reflector 17, causing it to rotate. Since a transparent cover 19 is fixed between the inner walls of the connecting hole 16, external light can penetrate the transparent cover 19 and shine on the reflector 17. The reflector 17 rotates continuously under the action of the wind, thereby forming a flashing reflected light. This reflected light has a stimulating and repelling effect on birds near the pole, forcing the birds away from the top of the crossarm 2. This not only effectively prevents birds from staying and nesting on the power facilities, but also reduces the pollution of insulators and lines by bird droppings or nesting materials. The bird-repelling mechanism relies on natural wind and light to repel birds, requiring no additional energy. It has a simple structure, reliable operation, and can maintain a stable bird-repelling effect for a long time.

[0031] Further, see attached document. Figure 5 As shown, the side wall of the limiting block 15 has an inclined surface. When the slide groove 13 moves the limiting block 15 upward by its own elastic force, the top of the limiting block 15 extends out of the interior of the slide groove 13 and fits against the outer wall of the side wall fixing plate 10 of the first protective cover 3.

[0032] By opening an inclined surface on the side wall of the limiting block 15, the limiting block 15 can be pressed into the slide groove 13 after contacting the slot 11. The elasticity of the slide groove 13 allows the limiting block 15 to extend out of the slide groove 13 and fit against the outer wall of the fixing plate 10 when it moves upward. This enables automatic limiting and locking between the first protective cover 3 and the second protective cover 4. This structure not only avoids the problem of positional deviation during manual docking, but also effectively prevents the two protective covers from loosening due to external vibration or wind after installation. This improves the stability and reliability of the device and ensures the protective effect under long-term use.

[0033] Further, see attached document. Figure 4 As shown, ventilation openings 20 for ventilation are provided on the opposite sides of the first protective cover 3 and the second protective cover 4.

[0034] This design allows for air circulation while ensuring protective functions. It reduces the resistance caused by wind pressure inside the protective cover, and the ventilation opening 20 helps to reduce stress in windy environments, improves the wind resistance of the device under harsh weather conditions, and extends the service life of the overall structure.

[0035] Further, see attached document. Figure 3 As shown, the opposing surfaces of the first protective cover 3 and the second protective cover 4 are provided with wrapping grooves 21. When the opposing surfaces of the first protective cover 3 and the second protective cover 4 are in contact, the wrapping grooves 21 on the first protective cover 3 and the second protective cover 4 will wrap around the outer wall of the support column 1.

[0036] Wrapping grooves 21 are provided on the opposite surfaces of the first protective cover 3 and the second protective cover 4. When the two are attached, the wrapping grooves 21 can wrap the outer wall of the support column 1. This structure enables the protective cover to automatically form a positioning and limiting effect with the support column 1 during installation, avoiding the risk of installation deviation or shaking. Through the support and constraint of the wrapping grooves 21, the attachment between the protective cover and the pole support column 1 is more stable, effectively improving the overall installation reliability and resistance to external forces, thereby further ensuring the bird protection effect of the power line.
