Description

Technical Field

[0001] This invention relates to the field of live-line working technology, and specifically to a stable telescopic insulating support rod. Background Technology

[0002] Live-line working is an important task in the power industry, and the tools used for live-line working are crucial to ensuring its safety. To ensure uninterrupted power supply to users, it is essential to strengthen the maintenance of power grid distribution lines. To prevent phase-to-phase short circuits and tripping of 10 kV lines, it is necessary to maintain safe distances between phases of 10 kV lines to ensure safe and reliable line operation. Insulated struts are commonly used to separate adjacent lines to a safe distance. However, most existing insulated struts can only withstand vertical forces. When encountering windy or other weather conditions, they cannot withstand forces in other directions besides vertical forces, resulting in unstable operations.

[0003] Chinese Patent Publication No. CN113161962B, Publication Date: September 29, 2023, discloses a Chinese patent entitled "An Adjustable Angle Spacer for Live-Line Operation," comprising three insulating rods, a central fixing mechanism, and three wire fixing mechanisms. All three insulating rods are mounted on the central fixing mechanism, and the three wire fixing mechanisms are respectively installed at one end of each of the three insulating rods. The central fixing mechanism includes two clamping plates, each with three first through holes arranged in a triangular pattern. Because the three insulating rods of this spacer are located on the same horizontal plane, it can only withstand vertical forces, making it unsuitable for use in harsh weather conditions and exhibiting poor stability. Summary of the Invention

[0004] This invention provides a stable telescopic insulating support rod. By setting a fixed rod and a connecting rod in the shape of a triangular pyramid frame, the stability of the insulating support rod is improved, and it can withstand forces in all directions and adapt to operation in harsh weather.

[0005] A further objective of this invention is to achieve a simple structure, light weight, reduced manufacturing costs, easy portability, and suitability for high-altitude live-line work.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stable telescopic insulating support rod, comprising a plurality of connecting rods arranged in a triangle and connected by a connector, wherein a telescopic rod is provided on the connector, and a plurality of fixed rods are provided above the plurality of connecting rods, the tail ends of which are respectively fixed to the connector; the head ends of the plurality of fixed rods are all fixed on a connecting sleeve, and the connecting sleeve is located above the plane formed by the plurality of connecting rods.

[0007] Preferably, several connecting rods and telescopic rods are on the same plane, with the connecting sleeve above the center of this plane. The insulating support rod has a centrally symmetrical design, the connecting sleeve is circular, and every two adjacent fixed rods and their connected connecting rods form a triangle. This design makes the force on the entire insulating support rod more even, better distributing forces in all directions and further enhancing its stability. At the same time, the centrally symmetrical structural design makes the insulating support rod easier to install and use, allowing for quick finding of the balance point and improving work efficiency.

[0008] Preferably, the fixing rods are arc-shaped and evenly arranged in an umbrella shape above several connecting rods. The umbrella opening faces downwards, and the fixing rods are Y-shaped, arranged symmetrically around the connecting sleeve, with the same angle between any two adjacent fixing rods. The arc-shaped fixing rods and umbrella-shaped arrangement can better adapt to different working environments, increasing the stability and adaptability of the insulating support rod. The Y-shaped fixing rod design can further improve its supporting strength, enabling it to withstand greater forces. At the same time, the evenly distributed angles ensure balanced force in all directions, further improving the stability of the insulating support rod.

[0009] Preferably, the included angle between the plane formed by the fixed rod and several connecting rods is 8 to 20 degrees. This included angle is preferably 15 degrees. By precisely controlling the included angle between the fixed rod and the connecting rods, the mechanical properties of the insulating strut can be optimized. A 15-degree included angle, verified through multiple experiments, is the optimal angle design, enabling the insulating strut to maintain stability while minimizing material usage and reducing manufacturing costs, while also improving its wind resistance and deformation resistance in harsh environments.

[0010] Preferably, several fixing rods are evenly distributed around the circumference of the connecting sleeve, and a connecting ring is provided on the upper surface of the connecting sleeve. The tail end of the fixing rod is fixed to the connecting member, and the tail end is located above the two connecting rods. The even distribution of the fixing rods ensures that the overall force of the insulating support rod is balanced, avoiding structural deformation or damage caused by uneven force. The tail end of the fixing rod being located above the two connecting rods allows for better utilization of the supporting force of the connecting rods, further improving the stability of the insulating support rod.

[0011] Preferably, several connecting rods are connected by connectors, and locking elements are provided at the connection points between the connecting rods and the connectors. These locking elements are tightened during assembly. During assembly, the locking elements at both ends of one connecting rod are simultaneously tightened, locking the connecting rod under the limiting effect of the connection operation. The other two connecting rods are locked in the same way, forming a stable triangular structure. The locking element design ensures a more secure connection between the connecting rods and the connectors, effectively preventing loosening due to vibration or external forces during use. By simultaneously tightening the locking elements, the stability of the triangular structure is ensured, allowing it to maintain good working condition in various complex environments, thus improving the safety and reliability of the insulating support rod.

[0012] Preferably, the connector has a through-hole at its center, and one end of the telescopic rod is positioned within this hole. The telescopic rod is electrically controlled. The connector is a T-junction with a through-hole at its center. The telescopic rod is extended and retracted using an electric remote control. This electrically controlled design makes the extension and retraction of the insulating support rod more convenient and faster, allowing for quick adjustment of the rod length according to actual operational needs, thus improving work efficiency. The T-junction design better distributes stress, improving the strength and stability of the connector. Simultaneously, the mounting hole ensures a more secure installation of the telescopic rod, further enhancing the overall performance of the insulating support rod.

[0013] Preferably, the other end of the telescopic pole is equipped with a latch, which includes a retaining frame with a groove. The retaining frame has a certain thickness to prevent the triangular support from twisting under stress. The groove has openings at both ends for placing three-phase conductors. The design of the latch and retaining frame ensures that the telescopic pole will not twist or deform under stress, improving the stability and reliability of the insulating support. The design of the groove with openings at both ends facilitates the placement of three-phase conductors, better meeting the needs of power operations. At the same time, the thickness of the retaining frame effectively prevents damage caused by excessive stress, extending the service life of the insulating support.

[0014] Preferably, the mounting bracket has a pull rod at the top opening, which can move within the bracket. One end of the pull rod has a pull ring on the outside of the bracket for easy operator access; pulling the ring removes the pull rod from the groove. The design of the pull rod and pull ring makes it easier for operators to maneuver the mounting bracket, improving work efficiency. The mobility of the pull rod can be adjusted according to actual needs, further enhancing the flexibility and adaptability of the insulating support rod, enabling it to better meet different working environments and requirements.

[0015] Preferably, a safety rope is provided on the connecting ring, with a hook at one end of the safety rope, and the telescopic rod adopts a sleeve telescopic structure. The sleeve is located at the end near the telescopic rod connector. The connecting sleeve is fixed with a connecting fixture, ensuring that the three connecting rods can be locked in place without displacement or disintegration. The hook can be easily hung on the crossarm. The design of the safety rope and hook ensures the safety of the insulated support rod during use, preventing falls due to unexpected situations. The telescopic rod with a sleeve telescopic structure can better adapt to different operational needs, improving the flexibility of the insulated support rod. The use of the connecting fixture ensures a more secure fixation of the connecting sleeve, preventing displacement or disintegration during use, further improving the stability and reliability of the insulated support rod.

[0016] The beneficial effects of the present invention are as follows: The present invention provides a stable telescopic insulating support rod. By setting a fixed rod and a connecting rod in the shape of a triangular pyramid frame, the stability of the insulating support rod is improved. It can withstand forces in all directions, adapt to operation in harsh weather, has a simple structure, is lightweight, reduces manufacturing costs, is easy to carry, and is suitable for high-altitude live-line work.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0024] Live-line working is a crucial task in the power industry, and live-line working tools are key to ensuring safety during such work. To ensure the safety, reliability, and efficiency of live-line working tools, basic technical requirements and design guidelines apply. Live-line working tools must possess excellent insulation properties to effectively isolate voltage and prevent electric shock accidents. Simultaneously, the structure of live-line working tools should be compact and robust to prevent safety hazards such as breakage and deformation. Live-line working tools should be suitable for various environments and working conditions, meeting the needs of different operations. Furthermore, live-line working tools should have good operability, facilitating use by operators; they should possess good durability and resistance properties, enabling long-term stable use. Additionally, live-line working tools should have good corrosion resistance to prevent corrosion in humid environments; they should comply with relevant standards and specifications, and be manufactured strictly according to quality requirements. Finally, live-line working tools should undergo rigorous quality inspection to ensure their quality meets standards.

[0025] In the power industry, for high-altitude live-line work and various scenarios requiring insulated support, the performance of insulating struts directly affects the safety and efficiency of the work. Traditional insulating struts often fall short in terms of stability, portability, and cost control, making it difficult to meet the demands of increasingly complex working environments. The stable, retractable insulating strut of this invention, with its innovative structural design, successfully solves these problems, bringing a new solution to related fields.

[0026] Example 1.

[0027] like Figure 1 As shown, this stable telescopic insulating support mainly consists of connecting rods, telescopic rods 1, fixed rods 9, and connecting sleeves 10. Several connecting rods are arranged in a triangular pattern, with telescopic rods 1 installed at the joints. The length of the support can be flexibly adjusted using the telescopic rods 1 to adapt to different working distance requirements. Above the connecting rods, several fixed rods 9 are arranged, with their tail ends fixed to the joints of the connecting rods and their heads all fixed to the connecting sleeves 10. Through this structural design, the fixed rods 9 and the connecting rods together form a triangular pyramid frame, giving the insulating support excellent stability.

[0028] like Figure 1 and Figure 3As shown, several connecting rods and telescopic rods 1 are located on the same plane, with the connecting sleeve 10 positioned above the center of this plane. This layout results in a centrally symmetrical design of the insulating support rod, providing excellent balance. The connecting sleeve 10 is designed as a circle, with each pair of adjacent fixed rods 9 and their connected connecting rods forming a triangle. In actual production, the choice of material for the connecting rods is crucial, typically employing high-strength carbon fiber composite materials with excellent insulation properties. This material is not only lightweight, effectively reducing the overall weight of the support rod and facilitating its portability, but also possesses outstanding strength, ensuring that the support rod will not deform or be damaged under significant external forces. In a simulated high-altitude operation experiment, the insulating support rod using connecting rods made of carbon fiber composite materials maintained its structural integrity without showing any signs of damage when subjected to wind and gravity equivalent to twice that of actual operations. In contrast, the support rod using traditional metal connecting rods exhibited significant bending deformation under the same conditions.

[0029] like Figure 1 and Figure 2 As shown, the telescopic pole 1 is designed to meet the varying length requirements of the support pole in different work scenarios. The telescopic pole 1 employs a multi-level nested structure design. The diameter and wall thickness of each level of the telescopic pole 1 are precisely calculated to ensure both sufficient strength and flexible extension / retraction. During extension and retraction, the built-in locking device can fix the telescopic pole 1 at the desired length. For example, in a power maintenance operation, the insulated support pole needs to be extended to a length of 5 meters to support live equipment. The operator can easily extend the support pole to the specified length by operating the control button on the telescopic pole 1 and secure it using the locking device. Throughout the entire operation, the telescopic pole 1 remains stable without any retraction, ensuring the smooth progress of the operation.

[0030] like Figure 1 and Figure 3 As shown, the fixing rod 9 is arc-shaped and evenly arranged in an umbrella shape above several connecting rods, with the umbrella opening facing downwards. The fixing rod 9 is Y-shaped and centrally symmetrically arranged around the connecting sleeve 10, with the same included angle between any two adjacent fixing rods 9. This unique design has multiple advantages. The arc-shaped fixing rod 9 can better distribute the force it bears. When subjected to external forces from different directions, the arc structure can evenly distribute the force along the curve of the rod, avoiding stress concentration. The umbrella shape increases the stability of the support rod, making it better adaptable to different working environments. For example, in strong winds, the umbrella structure can effectively reduce wind resistance and improve the wind resistance of the support rod. The Y-shaped fixing rod 9 design further improves its support strength. The Y-shaped structure has good mechanical stability and can withstand greater forces. In laboratory pressure tests, the insulating support rod using the Y-shaped fixing rod 9 can withstand 30% more maximum pressure than the traditional straight rod design.

[0031] like Figure 3 As shown, the included angle of the plane formed by the fixed rod 9 and several connecting rods is 8–20 degrees. After extensive experimental verification, the preferred included angle is 15 degrees. During the experiment, comprehensive mechanical performance tests were conducted on the insulating struts with different included angles. When the included angle is 15 degrees, the strut maintains stability while minimizing material usage. The stress conditions of the strut under different included angles were simulated using finite element analysis software. The results show that the stress distribution inside the strut is most uniform and the material utilization rate is highest at an included angle of 15 degrees. In practical applications, the insulating strut with a 15-degree included angle exhibits excellent wind resistance and deformation resistance in harsh environments, such as strong winds and heavy rain. In a power emergency repair operation during strong winds, the work team using the 15-degree included angle insulating strut successfully completed the support and repair work on the live equipment, while the team using struts with other included angles had to interrupt the operation due to insufficient strut stability.

[0032] Selection of Insulation Materials: High-quality insulation materials are selected for this insulating support rod to ensure excellent insulation performance. Commonly used insulation materials include polypropylene, polyurethane, and polyethylene. The structure has been optimized to ensure good stability and robustness. At the same time, overly complex design is avoided to allow operators to easily master it. A lightweight design is adopted. Using a small number of modules, the insulating support rod achieves high precision, stable performance, simple structure, and low cost while meeting requirements. The connection between modules is simple, and rapid assembly and disassembly facilitate transportation and storage. The manufacturing of the insulating support rod is subject to precision control to ensure its quality. Simultaneously, environmental protection requirements are considered during the manufacturing process to protect the environment.

[0033] like Figure 1 As shown, several fixing rods 9 are evenly distributed around the circumference of the connecting sleeve 10, and a connecting ring 11 is provided on the upper surface of the connecting sleeve 10. The tail end of the fixing rod 9 is fixed to the connecting piece 2, and the tail end is located above the two connecting rods. The even distribution of the fixing rods 9 ensures that the overall force of the insulating support rod is balanced, avoiding structural deformation or damage caused by uneven force. During the production process, the connecting sleeve 10 is made of high-strength insulating plastic, which not only ensures good insulation performance, but also has sufficient strength to fix the fixing rods 9. The design of the connecting ring 11 facilitates the connection with other equipment. For example, in some special operation scenarios, it is necessary to connect the insulating support rod to the lifting equipment. The connection operation can be quickly achieved through the connecting ring 11. The tail end of the fixing rod 9 is located above the two connecting rods, which can better utilize the supporting force of the connecting rods and further improve the stability of the insulating support rod. In the tensile test of the connecting sleeve 10, the connecting sleeve 10, made of high-strength insulating plastic, can still maintain the stable connection of the fixing rods 9 when subjected to a tensile force of more than 1000N, without loosening or breaking.

[0034] like Figure 1 As shown, several connecting rods are connected by connectors 2. To ensure the stability of the connection, locking elements 5 are provided at the connection between the connecting rod and connector 2. In the actual assembly process, taking one connecting rod as an example, the operator needs to simultaneously tighten the locking elements 5 at both ends of the connecting rod. The locking elements 5 are usually made of high-strength bolts, used in conjunction with specially designed nuts. As the nuts are gradually tightened, the axial tension generated by the bolts will cause the connecting rod and connector 2 to fit tightly together. Since connector 2 has a limiting effect on the connection of the connecting rod, the connecting rod is firmly locked as the locking elements 5 are tightened. Using the same method, the other two connecting rods can also be stably connected, thus forming a stable triangular structure. In the test of simulating a strong wind environment, the insulating support rod using the traditional connection method began to show signs of loosening at the connection between the connecting rod and connector 2 when the wind force reached level 8, while the insulating support rod designed with locking elements 5 of this invention remained as stable as ever at the connection point when the wind force reached level 12. The design of locking component 5 greatly enhances the connection strength between the connecting rod and connecting component 2, effectively preventing loosening of the connection due to vibration or external force during use, ensuring that the triangular structure can maintain good working condition in various complex environments, and significantly improving the safety and reliability of the insulating support rod.

[0035] The connector 2 is a three-way structure with a central mounting hole 3. This three-way design better disperses forces from different directions. In actual stress analysis, when the insulating support rod is subjected to external pressure, the three-way connector 2 can evenly distribute the force to the two connecting rods and the fixed rod 9, increasing its load-bearing capacity by approximately 30% compared to the traditional connector 2. One end of the telescopic rod 1 is set in the mounting hole 3, the size of which precisely matches the diameter of the telescopic rod 1 with tolerances controlled within a very small range, ensuring that the telescopic rod 1 will not wobble after installation. Simultaneously, the telescopic rod 1 can be operated electrically via remote control. In actual operation, operators can easily control the extension and retraction of the telescopic rod 1 using only a remote control. For example, in a power emergency repair operation, it is necessary to quickly adjust the length of the insulating support rod to support the faulty equipment. Using the electrically controlled telescopic rod 1 of this invention, the operator can adjust the support rod to the required length within 5 seconds, while a work team using the traditional manual adjustment method would take nearly 1 minute to complete the same operation, greatly improving work efficiency.

[0036] like Figure 1As shown, the other end of the telescopic rod 1 is equipped with a latch 6, which includes a fixing frame 7 with a groove. The fixing frame 7 has a certain thickness, a design to prevent the triangular support from twisting under stress. In the mechanical performance test of the fixing frame 7, when the thickness of the fixing frame 7 is 10mm, under a pressure equivalent to 1.5 times the maximum force in actual operation, the fixing frame 7 still maintains structural integrity and does not show any twisting deformation. The groove is open at both ends and is specifically designed to place the three-phase conductors. In power operation scenarios, placing the three-phase conductors in the groove can ensure the stability of the conductors and prevent them from shifting due to wind or other external forces, thus affecting operational safety. For example, in the maintenance of a high-voltage transmission line, the team using the insulating support rod of this invention was able to keep the three-phase conductors stably placed in the groove in strong wind conditions, allowing the operation to proceed smoothly, while the team using other support rods had to interrupt the operation and readjust due to conductor shifting.

[0037] The mounting bracket 7 has a pull rod 8 at its top opening, which can move on the mounting bracket 7. One end of the pull rod 8 has a pull ring on the outside of the mounting bracket 7, a design that greatly facilitates operation. In actual operation, the operator only needs to pull the pull ring to easily remove the pull rod 8 from the groove. For example, when it is necessary to place or remove three-phase conductors, the operator, standing in a safe position, can complete the removal or installation of the pull rod 8 in a very short time by pulling the pull ring, greatly improving work efficiency. The mobility of the pull rod 8 allows the operator to flexibly adjust it according to actual needs, further improving the flexibility and adaptability of the insulating support. In different power operation environments, such as working in confined spaces or scenarios requiring rapid conductor replacement, the movable design of the pull rod 8 can well meet the operational requirements, enabling the insulating support to better adapt to various complex operating environments and requirements.

[0038] A safety rope 12 is attached to the connecting ring 11, with a hook 13 at one end. In actual use, the hook 13 can be easily attached to the crossarm. The safety rope 12 is made of high-strength insulating material, and its breaking strength has been rigorously tested, capable of withstanding a weight of at least 1000 kg. In a simulated accidental fall test, when the insulated support pole unexpectedly lost its support, the safety rope 12 and hook 13 successfully prevented the pole from falling, ensuring the safety of the workers below. The design of the safety rope 12 and hook 13 provides additional safety assurance for the insulated support pole during use, effectively preventing falls due to unexpected situations and greatly improving operational safety.

[0039] The telescopic pole 1 adopts a sleeve 4 telescopic structure, with the sleeve 4 located at the end near the connector 2 of the telescopic pole 1. The sleeve 4 telescopic structure exhibits excellent stability and flexibility. In multiple telescopic tests, after 1000 telescopic operations, the sleeve 4 still functioned smoothly without any jamming or damage. The connecting sleeve 10 is fixed using a connecting fixture. This fixture employs a special clamp design to firmly secure the connecting sleeve 10, ensuring that the support will not shift or disintegrate when the three connecting poles are locked. During actual installation, operators can quickly and accurately fix the connecting sleeve 10 in place using the connecting fixture, ensuring the overall structural stability of the insulating support pole. In stability tests conducted on the insulating support pole fixed with the connecting fixture, even under simulated earthquake conditions, the insulating support pole remained stable without any displacement or disintegration, further demonstrating the important role of the connecting fixture in improving the stability and reliability of the insulating support pole.

[0040] Installation process.

[0041] Assembly of connecting rods and connector 2: First, initially connect the three connecting rods to the tee connector 2 respectively, ensuring the connection positions of the connecting rods and connector 2 are accurate. Then, using locking pieces 5, simultaneously tighten the locking pieces 5 at both ends of each connecting rod. Under the limiting action of connector 2, the connecting rods are firmly locked, forming a stable triangular structure. During this process, use a torque wrench to ensure that the tightening torque of the locking pieces 5 reaches the specified value to guarantee the firmness of the connection.

[0042] Installation of Telescopic Rod 1: Insert one end of the telescopic rod 1 into the mounting hole 3 in the center of the connector 2, adjust the position of the telescopic rod 1, and ensure that it is securely installed. Then, connect the wiring of the electric remote control device and test the telescopic rod 1 to ensure that its telescopic function is normal. During the testing process, check whether the telescopic rod 1's telescopic speed, stroke, and locking function meet the requirements.

[0043] Lock 6 and mounting bracket 7 installation: Install the mounting bracket 7 with the groove on the other end of the telescopic rod 1, ensuring that the mounting bracket 7 is securely installed. Then, install the pull rod 8 at the top opening of the mounting bracket 7, and adjust the flexibility of the pull rod 8 to ensure that the operator can easily pull the ring to move the pull rod 8.

[0044] Safety rope 12 and connecting fixture installation: Hook 13 at one end of safety rope 12 onto connecting ring 11, ensuring hook 13 is securely connected. Then, use the connecting fixture to fix connecting sleeve 10, adjusting the position of the connecting fixture to ensure that the support will not shift or disintegrate when the three connecting rods are locked. When installing the connecting fixture, carefully check its fixing effect to ensure that connecting sleeve 10 is tightly secured.

[0045] Usage Procedure: Before using the insulated support rod, adjust the length of the telescopic rod 1 according to the work requirements, extending or retracting it to the appropriate size, and secure it with the locking buckle 6. When working with live electricity at height, the operator connects the fixing frame 7 of the insulated support rod to the working equipment, ensuring a secure connection. When the support rod is subjected to external force, the operator closely monitors its condition. If any abnormality is found, stop work immediately and conduct inspection and adjustment. During use, regularly maintain and inspect the insulated support rod, including checking whether the connecting rod and fixing rod 9 are deformed or damaged, whether the telescopic function of the telescopic rod 1 is normal, and whether the connection parts are loose. If any problems are found, repair or replace the parts in a timely manner to ensure the performance and safety of the insulated support rod.

[0046] Example 2.

[0047] like Figure 4 and Figure 5 As shown, the other components of this embodiment are the same as those in Embodiment 1, except that the fixing rod 9 is straight and lies in the same plane as the connecting rod. This creates a simpler and more compact structural layout. Such a layout not only helps optimize space utilization but also improves the stability and rigidity of the overall structure to a certain extent. The three fixing rods 9 are connected by a T-joint connector. This connection method not only ensures a firm and reliable connection between the fixing rods 9 but also facilitates the coordinated work between the fixing rods 9 and the connecting rod. The design of the T-joint connector allows the force between the components to be evenly transmitted, thereby further enhancing the load-bearing capacity and deformation resistance of the entire structure.

[0048] Application environment of this invention: Applicable conductor type: JKLYJ-16~JKLYJ-240; Calculated cross section (mm2): 17.03~254.47; Calculated outer diameter (mm): 13.0~26.8; Operating voltage level: 10kV; Electrical performance: 100kV / 1min / 0.4m.

[0049] The stable, retractable, insulated support pole of this invention, through its unique triangular pyramid frame structure and stable architecture composed of a fixed pole 9 and connecting poles, can withstand forces in all directions and adapt to operations in harsh weather. In multiple tests simulating severe weather conditions, the insulated support pole remained stable in strong winds, heavy rain, and blizzards. Furthermore, the use of lightweight insulating materials, such as carbon fiber composites, for the connecting and fixed poles 9 reduces the pole's weight and manufacturing cost by approximately 40% compared to traditional metal insulated support poles. In actual carrying and use, operators can easily carry the support pole to the work site, making it ideal for high-altitude live-line work. For example, in a power emergency repair operation in a mountainous area, workers need to carry insulated support poles to climb to the mountaintop. Using the insulated support pole of this invention, workers can easily complete the climb and successfully finish the repair task, while teams using traditional, heavier insulated support poles expend a great deal of energy during the climb, affecting subsequent work efficiency.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
