Description

Technical Field

[0001] This invention relates to the field of overhead power transmission conductor technology, specifically a high tensile strength and wear-resistant overhead conductor. Background Technology

[0002] Overhead conductors, as a key component of power transmission systems, are widely used in high-voltage transmission, long-distance power supply in the field, and power grid construction in mountainous areas. Their structural strength and wear resistance directly affect the safe and stable operation of transmission lines. Traditional overhead conductors are mostly made of materials such as steel-cored aluminum stranded wire and high-strength aluminum alloy. They rely on the conductor's own structure to bear the tension and power transmission tasks. Some conductors will achieve basic wear resistance protection through surface coating or simple sheaths. They are the most commonly used transmission carriers in the current power transmission and distribution field.

[0003] However, existing overhead conductors have significant shortcomings in practical use. Conventional wear-resistant structures are mostly fixed and non-adjustable, making it impossible to dynamically adjust the protection points according to line wear and stress concentration. This can easily lead to excessive wear in some areas and over-protection overall. At the same time, traditional conductors have limited functions, lack self-powered and intelligent maintenance capabilities, and require external power to operate their auxiliary devices. This limits their application in the field, and external photovoltaic components are prone to dust accumulation and shading, leading to reduced efficiency. Manual maintenance is difficult and costly, making it difficult to meet the requirements for long-term stable service in complex environments. Therefore, we propose a high-tensile-strength wear-resistant overhead conductor. Summary of the Invention

[0004] The purpose of this invention is to provide a high tensile strength and wear-resistant overhead conductor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high tensile strength and wear-resistant overhead conductor, comprising an overhead conductor assembly, wherein the outer side of the overhead conductor assembly is provided with a wear-resistant component for axially sliding and adjusting the protective point position, and the interior of the wear-resistant component is provided with a moving component for driving the wear-resistant component to move along the conductor axis, wherein a photovoltaic panel for providing electrical energy is installed on the outer surface of the overhead conductor assembly, and a cleaning component for cleaning the surface of the photovoltaic panel and preventing dust from obstructing the power generation efficiency is provided on the outer side of the photovoltaic panel surface.

[0006] Preferably, the overhead conductor assembly includes an overhead conductor body, and a sliding groove is provided through both ends of the outer center of the overhead conductor body, with limit blocks fixedly connected to both ends of the two sliding grooves.

[0007] Preferably, the wear-resistant component includes two sliding sleeves, which are slidably fitted into two sliding grooves respectively. The outer sides of the two sliding sleeves are fixedly connected to the wear-resistant sleeve body, and the photovoltaic panel is installed in a ring on the outer side of the wear-resistant sleeve body. The inner wall of the end of the wear-resistant sleeve body near the cleaning component is rotatably connected to a toothed ring through a bearing.

[0008] Preferably, the moving component includes two right-angle connecting plates, which are respectively fixedly connected to the two ends of the center of one side of the wear-resistant sleeve body. A motor is fixedly connected to the center of the end of the two right-angle connecting plates closer to the cleaning component. A worm gear is fixedly connected to the rotating end of the motor, and a first gear is fixedly connected to the end of the worm gear away from the motor.

[0009] Preferably, the upper sliding sleeve has two first connecting blocks fixedly connected to the center of both sides near the two ends, and the interiors of the two first connecting blocks on the same side are rotatably connected to the outer sides of the worm gear through bearings. The upper sliding sleeve has two second connecting blocks fixedly connected to the ends near the gear ring on both sides.

[0010] Preferably, each of the two second connecting blocks has a fixed shaft fixedly connected to the side away from the worm gear, and each of the two fixed shafts has a second gear rotatably connected to the end away from the second connecting block, and the second gear and the first gear mesh with each other.

[0011] Preferably, both sides of the wear-resistant sleeve body are fixedly connected to a fixing frame, and both fixing frames are rotatably connected to a pulley. The upper ends of both pulleys are fixedly connected to a connecting shaft, and the upper outer sides of both connecting shafts are fixedly fitted with worm gears, and the worm gears mesh with the worm.

[0012] Preferably, the cleaning component includes a second right-angle connecting plate, which is fixedly connected to the side of the toothed ring away from the motor. A cleaning shaft is fixedly connected to the side of the second right-angle connecting plate close to the motor, and a plurality of cleaning brush heads arranged in a ring array are fixedly connected to the outer side of the cleaning shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting axially sliding wear-resistant components on the outside of the overhead conductor assembly and using moving components to achieve automatic drive, the protection points can be adjusted in real time according to line wear and stress concentration during long-term operation, and targeted coverage of easily scratched and damaged areas can be achieved, thereby realizing dynamic and precise wear-resistant protection and significantly improving the service life and environmental adaptability of overhead conductors.

[0014] 2. By adopting worm gear and worm wheel meshing transmission, and with pulley and slide groove guiding structure, the movement of the wear-resistant sleeve body is stable and smooth. Moreover, by utilizing the self-locking characteristics of the worm gear and worm wheel, the position of the wear-resistant component can be locked after the motor stops, effectively preventing the wear-resistant sleeve from slipping accidentally and improving the stability and safety of the conductor operation.

[0015] 3. By setting a ring-shaped photovoltaic panel on the outside of the wear-resistant sleeve body and matching it with a cleaning component driven by gears and gear rings, the photovoltaic panel can autonomously convert solar energy into electrical energy to power the system. At the same time, the cleaning brush head can automatically remove surface dust and blockages, ensuring long-term and stable power generation efficiency and achieving long-term autonomous operation without external power supply or manual maintenance.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-6As shown, the present invention provides a technical solution: a high tensile strength and wear-resistant overhead conductor, including an overhead conductor assembly 1. The outer side of the overhead conductor assembly 1 is provided with a wear-resistant component 2 for axial sliding and adjustment of the protective point. The inside of the wear-resistant component 2 is provided with a moving component 3 for driving the wear-resistant component 2 to move along the conductor axis. A photovoltaic panel 4 for providing electrical energy is installed on the outer surface of the overhead conductor assembly 1. A cleaning component 5 is provided on the outer surface of the photovoltaic panel 4 for cleaning the surface of the photovoltaic panel 4 and avoiding dust obstruction that affects the power generation efficiency.

[0020] Furthermore, the overhead conductor assembly 1, as the main body of power transmission, has high tensile strength to meet the requirements of long-distance, high-tension power transmission. The wear-resistant assembly 2 can move flexibly along the conductor axis to cover easily worn and scratched parts, thereby improving the wear resistance life of the conductor. The moving assembly 3 provides stable power to the wear-resistant assembly 2, enabling automatic adjustment of the protective position without the need for manual climbing. The photovoltaic panel 4 generates its own power using solar energy, providing clean energy for the moving and cleaning mechanism, enabling operation without external power supply. The cleaning assembly 5 cleans the surface of the photovoltaic panel 4 of dust, bird droppings, and sand, preventing shading from reducing power generation efficiency and ensuring long-term stable self-power supply for the entire device.

[0021] In the preferred embodiment of this technical solution, please refer to Figure 3 As shown, the overhead conductor assembly 1 includes an overhead conductor body 101. Slide grooves 102 are provided through the outer center of the overhead conductor body 101 at both ends. Limiting blocks 103 are fixedly connected to both ends of the two slide grooves 102.

[0022] Furthermore, the chute 102 is opened through the conductor axis and the inner wall is smooth to provide a stable sliding track for the wear-resistant component 2, reduce sliding resistance, and the limit block 103 is firmly fixed at both ends of the chute 102 to limit the movement stroke of the wear-resistant component 2, prevent excessive sliding from causing slippage, misalignment or structural damage, ensure that the wear-resistant component 2 moves back and forth within a safe range, and improve the overall operational safety and reliability.

[0023] In the preferred embodiment of this technical solution, please refer to Figure 4 As shown, the wear-resistant component 2 includes two sliding sleeves 201, which are slidably fitted in two sliding grooves 102 respectively. The outer sides of the two sliding sleeves 201 are fixedly connected to the wear-resistant sleeve body 202. The photovoltaic panel 4 is installed in a ring on the outer side of the wear-resistant sleeve body 202. The inner wall of the end of the wear-resistant sleeve body 202 near the cleaning component 5 is rotatably connected to a toothed ring 203 through a bearing.

[0024] Furthermore, the sliding sleeve 201 and the sliding groove 102 are fitted with a clearance, allowing for smooth sliding without jamming, while also preventing radial wobbling. The wear-resistant sleeve body 202 is made of multi-layer wear-resistant composite material, with an outer layer that is wear-resistant and scratch-resistant, and an inner layer that provides cushioning and shock absorption, forming a full-wrap protection for the conductor body. The annular photovoltaic panel 4 maximizes the reception of sunlight, improves power generation efficiency, and continuously supplies power to the motor 302. The toothed ring 203 is installed through a bearing, ensuring smooth rotation, and is used to transmit power and drive the cleaning component 5 to perform circumferential cleaning motion.

[0025] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, the moving component 3 includes two right-angle connecting plates 301. The two right-angle connecting plates 301 are fixedly connected to the two ends of the center of one side of the wear-resistant sleeve body 202. A motor 302 is fixedly connected to the center of the end of the two right-angle connecting plates 301 closer to the cleaning component 5. A worm gear 303 is fixedly connected to the rotating end of the motor 302. A first gear 304 is fixedly connected to the end of the worm gear 303 away from the motor 302.

[0026] Furthermore, the right-angle connecting plate 301 provides a rigid mounting base for the motor 302 to prevent displacement caused by operating vibration. The motor 302 adopts DC reduction gear, is powered by photovoltaic panel 4, can rotate in both directions, adjust speed, and has a self-locking function. The worm gear 303 is coaxially fixed with the output shaft of the motor 302, ensuring stable power transmission. The first gear 304 rotates synchronously with the worm gear 303, providing power to both the moving component 3 and the cleaning component 5, realizing dual-function drive by a single motor 302, simplifying the structure and reducing the failure rate.

[0027] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, the upper sliding sleeve 201 has two sides with the center of each side fixedly connected to the first connecting block 305. The interior of the two first connecting blocks 305 on the same side is rotatably connected to the outer sides of the worm gear 303 through bearings. The upper sliding sleeve 201 has two sides with the end near the toothed ring 203 fixedly connected to the second connecting block 306.

[0028] Furthermore, the first connecting block 305 is symmetrically arranged and has bearings installed inside to provide support for both ends of the worm gear 303, reducing rotational runout, reducing wear, and extending service life. The second connecting block 306 is positioned corresponding to the gear ring 203 and is used to install the gear transmission structure, ensuring that the transmission center is aligned with the gear ring 203, avoiding meshing deviation, jamming, or tooth skipping, and improving transmission stability.

[0029] In the preferred embodiment of this technical solution, please refer to Figure 5As shown, each of the two second connecting blocks 306 has a fixed shaft 307 fixedly connected to the side away from the worm 303. Each of the two fixed shafts 307 has a second gear 308 rotatably connected to the end away from the second connecting block 306, and the second gear 308 meshes with the first gear 304.

[0030] Furthermore, the fixed shaft 307 provides a stable rotation center for the second gear 308, ensuring stable gear rotation. The second gear 308 meshes with the first gear 304, smoothly transmitting power to the gear ring 203. The gear pair is hardened, wear-resistant, and impact-resistant, suitable for long-term outdoor operation. By matching the gear speed, the cleaning component 5 rotates at a suitable speed to achieve the best cleaning effect.

[0031] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, both sides of the wear-resistant sleeve body 202 are fixedly connected to a fixing bracket 309. The inside of each fixing bracket 309 is rotatably connected to a pulley 3010. The upper end of each pulley 3010 is fixedly connected to a connecting shaft 3011. The upper outer side of each connecting shaft 3011 is fixedly fitted with a worm gear 3012, and the worm gear 3012 meshes with the worm 303.

[0032] Furthermore, the fixed brackets 309 are symmetrically installed to provide positioning support for the pulleys 3010 and worm gears 3012. The pulleys 3010 are made of wear-resistant material and roll in close contact with the surface of the wire, greatly reducing sliding resistance. The connecting shaft 3011 rigidly connects the pulleys 3010 and worm gears 3012 to achieve synchronous rotation. The worm gears 3012 mesh with the worm 303 for transmission, which has a large reduction ratio and self-locking properties. The position can be locked when the motor 302 stops rotating, preventing the wear-resistant components 2 from sliding freely and achieving accurate positioning of the protection point.

[0033] In the preferred embodiment of this technical solution, please refer to Figure 6 As shown, the cleaning component 5 includes a right-angle connecting plate 501, which is fixedly connected to the toothed ring 203 on the side away from the motor 302. A cleaning shaft 502 is fixedly connected to the side of the right-angle connecting plate 501 close to the motor 302. Multiple cleaning brush heads 503 arranged in a ring array are fixedly connected to the outer side of the cleaning shaft 502.

[0034] Furthermore, the right-angle connecting plate 501 and the toothed ring 203 rotate synchronously, driving the cleaning shaft 502 to make a circular motion. The cleaning shaft 502 is lightweight and high-strength, and does not deform when rotating at high speed. The cleaning brush head 503 is made of flexible and wear-resistant fiber, which can remove dust and bird droppings without scratching the surface of the photovoltaic panel 4. Multiple brush heads are distributed in a ring, cleaning without dead corners, maintaining the high light transmittance and high power generation efficiency of the photovoltaic panel 4.

[0035] Working principle: When this device is working, the overhead conductor body 101 serves as the load-bearing and power transmission foundation. The wear-resistant component 2 is sleeved on the outside of the overhead conductor body 101 through the cooperation of the sliding sleeve 201 and the sliding groove 102. The electric energy generated by the photovoltaic panel 4 drives the motor 302, which drives the worm gear 303 to rotate. The worm gear 303 meshes with the worm wheel 3012, which drives the pulley 3010 to rotate, so that the wear-resistant sleeve body 202 moves smoothly along the axial direction of the overhead conductor body 101. It can automatically adjust to the critical protection point according to the line wear and stress conditions. The limit block 103 limits the sliding stroke of the sliding sleeve 201 to prevent the wear-resistant sleeve body 202 from slipping off, thereby realizing dynamic and fixed-point wear-resistant protection for the overhead conductor body 101 and greatly improving the conductor's resistance to scratches, tension and aging.

[0036] Meanwhile, the photovoltaic panel 4, which is installed in a ring on the outside of the wear-resistant sleeve body 202, continuously converts solar energy into electrical energy, providing self-powered power to the motor 302 without the need for an external power source. The rotation of the worm gear 303 synchronously drives the first gear 304 to rotate, and through the meshing transmission of the second gear 308 and the gear ring 203, it drives the cleaning component 5 to make a circular motion around the photovoltaic panel 4. The cleaning brush head 503 continuously cleans the surface of the photovoltaic panel 4 of dust, bird droppings and sand, avoiding the reduction of power generation efficiency due to sunlight blockage, and ensuring the long-term stable operation of the moving component 3 and the cleaning component 5. This gives the conductor multiple effects, including high tensile strength, wear resistance, autonomous movement, photovoltaic power generation and automatic cleaning.
