Description

Technical Field

[0001] This invention relates to the field of power line operation and maintenance technology, and more specifically, to a method and device for deterring birds from the crossarms of 10kV distribution network towers. Background Technology

[0002] 10kV distribution lines are a crucial link in the power system's supply of electricity to users, and their reliability directly affects social welfare and economic production. However, the nesting of birds on pole crossarms poses a serious threat to the safe operation of distribution lines: twigs, weeds, and other materials from bird nests can easily cause short circuits and tripping of lines, leading to power outages, equipment damage, and potentially fires in dry seasons or forest areas. Furthermore, faults caused by bird nests significantly increase the number of households experiencing power outages, affecting the achievement of power supply reliability indicators. Line tripping caused by bird nests accounts for 20.69% of the total number of trips throughout the year, and the number of households experiencing power outages during these outages accounts for 12.21% of the total number of households experiencing outages due to faults throughout the year.

[0003] Traditional methods for dealing with bird nests on power distribution lines have many shortcomings and fail to meet the needs for efficient, economical, and sustainable bird control. For example, manually removing bird nests is a remedial measure that cannot prevent birds from nesting again. It also requires a large amount of manpower for inspection and removal, resulting in high maintenance costs. In addition, there is a possibility that the power will trip the day after the bird nest is removed, making the bird control effect minimal. Reflective bird deterrents rely on a single optical bird deterrent principle, which birds can easily adapt to. Their bird control effect decreases significantly after long-term use and cannot fundamentally stop nesting behavior. Existing bird control technologies also have problems such as the risk of material conductivity, the need for close contact with live equipment during installation, and high costs that limit their widespread adoption. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a method and device for deterring birds from nesting on the crossarms of 10kV distribution network towers. By using two sets of insulated triangular prisms of different specifications installed non-parallel, birds are physically prevented from nesting without causing harm. Magnetic connections, combined with modified insulated operating rods, enable safe and convenient installation with strong stability and adaptability. The synergistic effect of materials, structure, and magnetic attraction, along with a lightweight design that simplifies the process, eliminates the need for tower modifications, significantly reduces power outages caused by bird nests, improves power supply reliability, and has significant potential for widespread adoption.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A method for deterring birds from crossarms on 10kV distribution network towers includes the following steps:

[0007] S1. Use insulating materials to integrally form two triangular prisms with different specifications according to the design drawings. The two triangular prisms with different specifications form a set of bird repellers. Open at least 3 magnet holes on the installation surface of the triangular prism, and fix the N52 magnets in the magnet holes with special magnet glue.

[0008] Manufacture an experimental cross arm that is the same as the existing cross arm of the 10kV distribution network line pole. Place the manufactured triangular prism on the experimental cross arm, simulate the actual wind force environment with different wind directions outdoors, and conduct thrust tests on the triangular prism in the horizontal, vertical, and 45° angle directions of the cross arm. Combine the common maximum wind force levels outdoors to set the equivalent thrust values in the above three directions. Ensure that when the triangular prism is under the action of this equivalent thrust, the moving distance is less than the set threshold, and the triangular prism is considered qualified.

[0009] S2. Modify the insulating operating rod, and fix an iron sheet on its top. The iron sheet is divided into a fitting part and an adjusting part with the connecting part as the boundary. The fitting part is used to adsorb the triangular prism, and the adjusting part is used to adjust the installation position of the triangular prism.

[0010] S3. Adsorb the triangular prism through the modified insulating operating rod. The operator lifts the triangular prism to the predetermined installation position in the safe area, makes the other magnet at the other end of the triangular prism fit with the surface of the cross arm to achieve stable adsorption, and then adjusts the position of the triangular prism until the triangular prism is completely adsorbed on the surface of the cross arm. The two triangular prisms with different specifications are arranged non-parallel after installation, reducing the effective support area of the cross arm and preventing birds from placing nesting materials.

[0011] As a preferred solution of the present invention, the bottom surface of one triangular prism is an equilateral triangle with a side length of 3 - 5 cm, and the bottom edge of the other triangular prism is 3 - 5 cm, and the side length of the isosceles triangle is 5.8 - 7 cm. The length of the triangular prism is 35 - 50 cm.

[0012] As a preferred solution of the present invention, the insulating material is modified polyethylene terephthalate PETG, and the color is orange.

[0013] As a preferred solution of the present invention, the equivalent thrust value in S1 is calculated by the following formula: ;

[0014] Where, is the equivalent thrust value; is the wind force correction coefficient; is the common maximum wind speed outdoors; is the windward area of the triangular prism; is the air density.

[0015] As a preferred embodiment of the present invention, the set threshold in S1 is calculated by the following formula: ;

[0016] in, To set a threshold; The total magnetic attraction force of the triangular prism is given, and , The number of magnets. The rated attractive force of a single N52 type magnet. This is the adsorption and adhesion correction factor; The coefficient of friction is the friction coefficient between the triangular prism and the surface of the crossarm.

[0017] As a preferred embodiment of the present invention, the installation process in S3 is as follows:

[0018] S31. The bottom surface of the triangular prism is attached to the bonding area, and one of the magnets is magnetically fixed to the bonding area.

[0019] S32. Then move the insulating operating rod so that the bottom surface of the other end of the triangular prism is attached to the top surface of the tower crossarm. Then adjust the insulating operating rod so that more magnets are magnetically attracted to the top surface of the tower crossarm. Then remove the insulating operating rod.

[0020] S33. Use the adjustment part to push the inclined surface of the triangular body adsorbed on the crossarm of the tower, and fine-tune the position of the triangular prism to ensure that the mounting surface of the triangular body is completely attached to the crossarm of the tower, and all magnets are magnetically attracted to the top surface of the crossarm of the tower.

[0021] As a preferred embodiment of the present invention, it also includes S4: after installation, using a drone to check the position of the installed triangular prism; in the later maintenance stage, the installation status of the triangular prism and the bird-repelling effect are observed through the imaging equipment carried by the drone.

[0022] This invention also provides a bird deterrent device for the crossarm of a 10kV distribution network tower, comprising:

[0023] The first triangular prism and the second triangular prism, wherein the cross-section of the first triangular prism is an equilateral triangle and the cross-section of the second triangular prism is an isosceles triangle, wherein the vertex angle of the isosceles triangle is less than 60° and the side length of the base of the isosceles triangle is equal to the side length of the equilateral triangle;

[0024] The first triangular prism and the second triangular prism are integrally molded from insulating material;

[0025] The magnet is installed in the mounting grooves opened on the mounting surfaces of the first triangular prism and the second triangular prism, and the magnet is fixed to the first triangular prism and the second triangular prism using magnet-specific glue.

[0026] As a preferred embodiment of the present invention, after the first triangular prism and the second triangular prism are installed as a group, the sharp edges at the top of the two are arranged in a staggered manner.

[0027] As a preferred embodiment of the present invention, the first triangular prism and the second triangular prism are made of orange modified polyethylene terephthalate (PETG) by 3D printing; there is a 1mm installation gap between the magnet and the wall of the mounting groove.

[0028] The beneficial technical effects of this invention are:

[0029] This invention employs two sets of triangular prisms of different specifications, installed vertically and horizontally without parallelism, which significantly reduces the effective support area of ​​the pole crossarm, making it impossible for birds to stably place branches or other nesting materials. This invention repels birds through physical barriers without using designs that harm birds, thus blocking nesting behavior at the source. The warning color properties of the orange PETG material provide a visual warning to birds, further enhancing the bird deterrence effect.

[0030] This invention replaces traditional bolt connections with magnetic fixing. Combined with a modified insulating operating rod with an added iron plate on top, operators can install and adjust the bird deterrent device in a safe area without close contact with the crossarm and live equipment, effectively reducing the risk of working at height and electric shock. The 1mm gap between the magnetic attraction and the installation slot, along with the special adhesive, ensures installation stability and simplifies the installation process, achieving a 100% installation compatibility rate.

[0031] This invention optimizes and upgrades the entire installation process through the deep synergy of material properties, structural design, and magnetic connection. The selected orange PETG material combines lightweight and toughness, and when combined with two sets of standardized triangular prism structures of different specifications, the overall weight of the bird repeller is significantly reduced, ensuring that the total suction force of the four N52 magnets is sufficient to achieve a stable fit with the crossbar. This lightweight advantage, combined with the magnetic connection method and the modified insulated operating rod that allows for quick attachment of the bird repeller, along with its lightweight nature, allows operators to easily lift and adjust its position. The inclined structure of the triangular prisms also assists in positioning, eliminating the need for close contact with the crossbar; a single person can complete the installation process. This ensures installation stability and completely solves the pain points of traditional installation methods, such as cumbersome procedures and high safety risks.

[0032] This bird deterrent device requires no modification to the existing tower structure, meets the standard construction requirements of the distribution area, and can be widely used on the crossarms of various 10kV distribution network lines. Its application significantly reduces line tripping caused by bird nests, effectively reduces the number of households affected by power outages, helps power supply companies achieve their annual power outage time targets, improves power supply reliability, and provides stable power security for social welfare and economic production. It has significant social benefits and industry promotion value. Attached Figure Description

[0038] In order to clearly understand the technical means of the present invention and implement it according to the content of the specification, the following further describes the specific embodiments of the present invention in detail with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention but not to limit the scope of the present invention.

[0039] Combined with Figure 1-4 , the present invention provides the following embodiments:

[0040] A method for driving birds away from the cross arm of a 10 kV distribution network line tower includes the following steps:

[0041] S1. Prepare two triangular prisms of different specifications integrally formed with insulating materials according to the design drawings. The two triangular prisms of different specifications form a set of bird repellers. Open at least 3 magnet holes on the installation surface of the triangular prism, and fix the N52 type magnets in the magnet holes with special magnet glue;

[0042] Make an experimental cross arm the same as the existing 10 kV distribution network line tower cross arm. Place the made triangular prism on the experimental cross arm, simulate the actual wind force environment in different outdoor wind directions, and conduct thrust tests on the triangular prism in the horizontal direction, vertical direction and 45° angle direction of the cross arm respectively; Combine the equivalent thrust values in the above three directions according to the common maximum wind force level outdoors, and ensure that the movement distance of the triangular prism is less than the set threshold under the action of the equivalent thrust, and the triangular prism is regarded as qualified;

[0043] S2. Modify the insulating operating rod, fix an iron sheet on its top, and divide the iron sheet into a fitting part 51 and an adjustment part 52 with the connecting part as the boundary. The fitting part 51 is used to adsorb the triangular prism, and the adjustment part 52 is used to adjust the installation position of the triangular prism;

[0044] S3. The modified insulated operating rod is used to adsorb the triangular prism. The operator lifts the triangular prism to the predetermined installation position in a safe area, so that the other magnet at the other end of the triangular prism is attached to the surface of the crossarm to achieve stable adsorption. Then the position of the triangular prism is adjusted until the triangular prism is completely adsorbed on the surface of the crossarm. The two triangular prisms of different specifications are arranged in a non-parallel manner after installation, which reduces the effective support area of ​​the crossarm and prevents birds from placing nesting materials.

[0045] Furthermore, one of the triangular prisms has an equilateral triangle base with a side length of 3-5cm, and the other triangular prism has an isosceles triangle base with a side length of 3-5cm and a side length of 5.8-7cm. The length of the triangular prisms is 35-50cm. Preferably, there is a triangular prism with a 4cm equilateral triangle cross-section and a length of 45cm, and a triangular prism with a 4cm base, 6cm side lengths, and a length of 45cm. This combination of specifications allows the two prisms to form a better non-parallel angle after installation, further improving the bird-proofing effect.

[0046] The magnet is provided in four pieces. The preferred magnet size is 15mm. 10 With a thickness of 2mm, four magnets are evenly distributed on the triangular prism mounting surface, providing a total suction force of up to 2.4kg. This ensures that the bird repeller remains firmly attached even under outdoor wind and other environmental influences, eliminating the need for secondary reinforcement.

[0047] Furthermore, the insulating material is modified polyethylene terephthalate (PETG) and is orange in color.

[0048] PETG material is high in strength, tough and durable, easier to process and mold, and has a lower cost. The cost of a single bird deterrent can be controlled within 10 yuan. Its insulation resistance is greater than 5000M ohms, which is fully compatible with the insulation requirements of 10kV distribution network lines. The orange warning color not only provides a visual warning to birds, but also makes it easy for operators to quickly locate the installation position in complex outdoor environments.

[0049] Furthermore, the equivalent thrust value described in S1 is calculated using the following formula: ;

[0050] in, This is the equivalent thrust value; This is a wind correction factor, ranging from 0.6 to 0.8, calibrated based on meteorological data of the area where the 10kV distribution network line is located; This represents the maximum wind speed commonly seen outdoors. The windward area of ​​the triangular prism; The value is for air density, taken at standard atmospheric pressure and 20°C.

[0051] Based on the principle of wind force on solid objects in fluid mechanics, using the square term of wind speed... Characterizing the nonlinear relationship between wind force and wind speed, the windward area is introduced. Quantify the effective area of ​​the triangular prism affected by wind force using a wind correction factor. It adapts to the impact of meteorological differences in different regions such as mountains and plains on actual wind force, and finally accurately calculates the ultimate thrust that the triangular prism needs to withstand in complex outdoor wind conditions, providing a quantitative basis for subsequent stability testing.

[0052] Furthermore, the threshold value set in S1 is calculated using the following formula: ;

[0053] in, For setting a threshold, the unit is mm; The total magnetic attraction force of the triangular prism is given, and , This represents the number of magnets; in this embodiment, it is set to 4. The rated attractive force of a single N52 type magnet. This is the adsorption and adhesion correction factor, with a value ranging from 0.9 to 1.0, determined based on the actual degree of adhesion between the magnet and the crossarm surface; The coefficient of friction between the triangular prism and the crossbeam surface is 0.3-0.5.

[0054] Based on the principle of static equilibrium, utilizing the total magnetic attraction force With coefficient of friction The product of the two forces represents the maximum static friction between the triangular prism and the crossarm, and is expressed in conjunction with the equivalent thrust value. The ratio determines the moving distance threshold. Essentially, it is the critical equilibrium state where magnetic friction resists wind thrust, where the adsorption and adhesion correction coefficient is... This is used to compensate for the decrease in attractive force caused by imperfect fit between the magnet and the crossarm during actual installation, ensuring that the threshold setting meets the outdoor stability requirements while avoiding material waste caused by over-design.

[0055] Furthermore, the installation process in S3 is as follows:

[0056] S31. The bottom surface of the triangular prism is attached to the bonding area, and one of the magnets is magnetically fixed to the bonding area.

[0057] S32. Then move the insulating operating rod so that the bottom surface of the other end of the triangular prism is attached to the top surface of the tower crossarm. Then adjust the insulating operating rod so that more magnets are magnetically attracted to the top surface of the tower crossarm. Then remove the insulating operating rod.

[0058] S33. Use the adjustment part to push the inclined surface of the triangular body adsorbed on the crossarm of the tower, and fine-tune the position of the triangular prism to ensure that the mounting surface of the triangular body is completely attached to the crossarm of the tower, and all magnets are magnetically attracted to the top surface of the crossarm of the tower.

[0059] The step-by-step adsorption process first ensures that the bird deterrent device does not fall off during installation by fixing it at a single point. Then, the insulated operating rod is moved to allow more magnets to adhere to the top surface of the tower crossarm, improving stability and facilitating the removal of installation tools. Finally, by utilizing the force characteristics of the inclined plane of the triangular prism and making precise fine adjustments through the adjustment unit, the problems of difficult alignment and poor fit in traditional installation are solved, achieving safe and efficient installation.

[0060] Furthermore, this also includes S4, after installation, using drones to check the position of the installed triangular prisms; in the later maintenance phase, using imaging equipment carried by drones to observe the installation status of the triangular prisms and their bird-repelling effect.

[0061] Drones can perform inspections and monitoring remotely without the need for manual climbing, which reduces the risks of working at heights and improves maintenance efficiency. At the same time, they can promptly detect problems such as bird deterrents falling off or shifting, enabling efficient management throughout the entire lifecycle and ensuring the continuous and stable effectiveness of bird deterrence.

[0062] This invention also provides a bird deterrent device for the crossarm of a 10kV distribution network tower, comprising:

[0063] The first triangular prism and the second triangular prism, wherein the cross-section of the first triangular prism is an equilateral triangle and the cross-section of the second triangular prism is an isosceles triangle, wherein the vertex angle of the isosceles triangle is less than 60° and the side length of the base of the isosceles triangle is equal to the side length of the equilateral triangle;

[0064] The first triangular prism and the second triangular prism are integrally molded from insulating material;

[0065] The magnet is installed in the mounting grooves opened on the mounting surfaces of the first triangular prism and the second triangular prism, and the magnet is fixed to the first triangular prism and the second triangular prism using magnet-specific glue.

[0066] Furthermore, when the first and second triangular prisms are installed as a group, their sharp top edges are arranged in a staggered, layered manner. This structure further disrupts the smooth support surface of the crossbeam, making it impossible for birds to find a stable footing or nesting location. Combined with the non-parallel arrangement, the bird-proofing effect is significantly improved.

[0067] Furthermore, the first and second triangular prisms are made of orange modified polyethylene terephthalate (PETG) using 3D printing. 3D printing enables standardized mass production, further reducing the probability of defective products. The orange PETG material possesses multiple characteristics, including environmental friendliness, durability, and warning properties, making it suitable for long-term outdoor use. A 1mm installation gap exists between the magnet and the wall of the mounting groove. This gap facilitates the insertion and fixation of the magnet and allows for fine-tuning of its position during installation, ensuring a complete fit between all magnets and the crossarm, thus improving adsorption stability.

[0068] In practice, the purchase price of traditional optical bird deterrents, which are widely used, is 50-60 yuan per unit. Two deterrents are typically installed on a double-crossarm pole, so the cost per pole is 100-120 yuan. However, the cost of this bird deterrent is only 10 yuan per unit. Based on installing two per pole, the cost per pole is only 20 yuan, a difference of 80-100 yuan per unit. Therefore, the large-scale and widespread application of this bird deterrent will significantly reduce costs. Furthermore, improved power supply reliability means fewer households will be affected by power outages, and electricity bill losses due to power outages in the Liangzihu area will be effectively controlled.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
