Description

Technical Field

[0001] The invention relates to the technical field of high-voltage overhead line construction, and in particular to a device and method for preventing flying birds from building nests on cement poles. Background Art

[0002] As human beings become more aware of the protection of the natural ecological environment, the number of birds is gradually increasing. Bird nests can be seen everywhere on overhead line fittings. Even the traditional bird repellents on some towers can no longer prevent the construction of bird nests. Line faults caused by flying birds are increasing day by day, which has a great impact on line operation and production. Bird nests built on high-voltage overhead lines directly cause line grounding, quick disconnection and other faults, causing substation protection to operate and line power outages, affecting the normal production of oil wells. It has been observed that birds begin to build nests, lay eggs and hatch on transmission line towers in spring. Most of them are magpies, crows and other birds. They like to build nests on the double cross arms of the line's tension poles, corner poles, terminal poles and other pole types. After observing the birds building nests on the double cross arms of cement poles, it is necessary to first choose the gap of the double cross arms as the starting point, and the gap is only available at the M washers and double-threaded screws of the double cross arms. When building the nest, first insert branches, iron wires, etc. into the M washers or double-threaded screws of the double cross arms to fix them, and then gradually strengthen and make them bigger. When there are thunderstorms and strong winds, the loose bird's nest will cause the line to be grounded and short-circuited.

[0003] Most of the existing power line fittings use the following traditional bird repellent devices:

[0004] 1) Pneumatic reflective bird repeller: Based on the principle that birds are afraid of light and colors, it uses intermittent reflected light to repel birds and prevent them from nesting in dangerous parts of line towers. However, pneumatic bird repellers have significant defects and a high failure rate. In windless weather, the wind bowl cannot rotate, thus losing the ability to repel and scare birds. They also suffer from severe wear, a short service life, and a high cost.

[0005] 2) Ultrasonic bird repeller: Once the device senses birds flying close, it will sound a warning to drive the birds away from roosting and nesting in dangerous areas on the towers. However, after a period of use, the birds adapt to and get used to the eagle model and screams of the bird repeller, and start to build nests in dangerous parts of the line towers again, thus failing to effectively control the occurrence of bird damage and having a high cost.

[0006] 3) Bird repellent spikes: Since they are made of metal, they are easily corroded, damaged and fall off, causing the bird protection device itself to damage the line and cause grounding faults. Summary of the invention

Bird nests can be seen everywhere on overhead line fittings. Even the traditional bird repellents on some towers can no longer prevent the construction of bird nests.

[0040] In some optional embodiments, the fixing component 5 includes a first fixing plate, a second fixing plate and a plurality of fixing elements, the second opening of the fastening sleeve 4 is arranged corresponding to the first opening of the insulating body 3, the first fixing plate is arranged along one side of the first opening and the second opening, and the second fixing plate is arranged along the other side of the first opening and the second opening.

[0041] Optionally, the fixing element is a bolt assembly, and the bolt assembly includes a bolt and a nut. The multiple mounting holes of the first fixing plate are evenly arranged. The multiple mounting holes of the second fixing plate are evenly arranged.

[0042] In some optional embodiments, the radius of the fastening sleeve 4 increases from the end portion far from the insulating body 3 to the direction close to the insulating body 3 .

[0043] Specifically, in the height direction of the cement pole 1, the diameter of the cement pole 1 changes with the height. Generally, the bottom diameter of the cement pole 1 is larger than the top diameter of the cement pole 1. As the height of the cement pole 1 increases, the diameter of the cement pole 1 gradually decreases. The fastening sleeve 4 is truncated cone-shaped, which can better adapt to the diameter change of the cement pole 1, so that it can better fit the cement pole 1.

[0044] In some optional embodiments, the angle between the radius of the circular ring formed by the end edge of the fastening sleeve 4 away from the insulating body 3 and the generatrix of the side wall of the fastening sleeve 4 is 100° to 110°.

[0045] In some optional embodiments, the angle between the radius of the circular ring formed by the end edge of the fastening sleeve 4 away from the insulating body 3 and the generatrix of the side wall of the fastening sleeve 4 is 105°.

[0046] Specifically, in the height direction of the cement pole 1, the diameter of the cement pole 1 changes with the height. Generally, the bottom diameter of the cement pole 1 is larger than the top diameter of the cement pole 1. As the height of the cement pole 1 increases, the diameter of the cement pole 1 gradually decreases. The fastening sleeve 4 is truncated cone-shaped, which can better adapt to the diameter change of the cement pole 1, so that it can better fit the cement pole 1.

[0047] In some optional embodiments, the ratio between the radius of the circular ring formed by the end edge of the fastening sleeve 4 away from the insulating body 3 and the height of the fastening sleeve 4 is 4:1 to 3:1.

[0048] Specifically, the maximum diameter of the fastening sleeve 4 is equal to the maximum diameter of the cement pole 1, and the minimum diameter of the fastening sleeve 4 is equal to the minimum diameter of the cement pole 1. When using the device for preventing birds from nesting on cement poles, the target position of the cement pole 1 is first determined. Since the radius of the cement pole 1 gradually decreases in its height direction, when the insulating body and the fastening sleeve 4 of the device are mounted on the cement pole 1, the staff is required to confirm whether the current diameter of the fastening sleeve 4 meets the diameter of the cement pole 1. If the diameter of part of the fastening sleeve 4 is slightly smaller than the diameter of the target position, it is necessary to adjust the height of the fastening sleeve 4 on the cement pole 1, and cut a small hole at the end with a smaller diameter of the fastening sleeve 4, so as to better adapt to the diameter of the target position of the cement pole 1.

[0049] In some optional embodiments, combined with Figure 3 , Figure 4 and Figure 5 The fastening sleeve 4 includes a fastening body and a clamp. One end of the fastening body is rotatably connected to the insulating body around the through hole 31, and the other end of the fastening body is connected to the clamp.

[0050] In some optional embodiments, the fastening body includes multiple fastening petals 41 along its circumference, one end of each fastening petal 41 is rotatably connected to the insulating body 3 around the through hole 31, and a clamp is connected to one end of each fastening petal 41 away from the insulating body 3.

[0051] In some optional embodiments, each fastening flap 41 and the insulating body 3 are hingedly connected to the peripheral side of the through hole.

[0052] Specifically, the maximum diameter of the fastening sleeve 4 is equal to the maximum diameter of the cement pole 1, and the minimum diameter of the fastening sleeve 4 is equal to the minimum diameter of the cement pole 1. When using the device for preventing birds from nesting on cement poles, the target position of the cement pole 1 is first determined. Since the radius of the cement pole 1 gradually decreases in its own height direction, when the insulating body and the fastening sleeve 4 of the device are mounted on the cement pole 1, the staff is required to confirm whether the current diameter of the fastening sleeve 4 meets the requirements of the cement pole 1. If the diameter of part of the fastening sleeve 4 is slightly smaller than the diameter of the target position, it is necessary to adjust the angle of each fastening petal 41 relative to the insulating body 3, thereby adjusting the diameter of the fastening sleeve 4, so as to better adapt to the diameter of the target position of the cement pole 1. After the diameter adjustment is completed, the clamp is mounted on each fastening petal 41, so as to fix the fastening sleeve 4.

[0053] In some optional embodiments, a crimping sleeve 42 is provided at one end of the fastening body away from the insulating body 3 , and the clamp is provided on the crimping sleeve 42 .

[0054] On the other hand, the present invention provides a method for preventing birds from building nests, which is achieved by any of the above devices for preventing birds from building nests on cement poles, and the method includes: opening a fixing component and unfolding it along a first opening of the insulating body itself, allowing the cement pole to enter a fastening sleeve through the first opening of the insulating body; setting a clamping assembly on the double crossarm; locking the fixing component; and adjusting the height of the fastening sleeve according to the diameter of the target position of the cement pole.
