A tensile anti-breakage overhead insulated conductor

Abstract

This invention belongs to the field of power equipment technology, specifically a tensile-resistant and fracture-resistant overhead insulated conductor, comprising a U-shaped conductor body with a base on its inner side. Positioning plates are rotatably mounted at both ends of the base, and the two positioning plates are parallel to each other. A torsion spring shaft is installed between each positioning plate and the base. A fixing component A is located at the end of each positioning plate away from the torsion spring shaft, and the fixing component A is used to fix the conductor body. When the conductor body is stretched, the tension first acts on the fixing component A, which drives the positioning plates to rotate around the torsion spring shaft, causing the two positioning plates to unfold outwards. This process achieves dynamic release of the conductor body, distributing the tension originally concentrated at a single point to a longer section of the conductor body, reducing the tension per unit length of the conductor body, and effectively preventing the conductor body from breaking due to excessive local stress.

Description

Technical Field

[0001] This invention belongs to the field of power equipment technology, specifically a tensile-resistant and fracture-resistant overhead insulated conductor. Background Technology

[0002] Overhead insulated conductors, as a key component of power transmission and distribution systems, are widely used in urban power distribution networks, rural power grid upgrades, and industrial park power supply, among many other fields. With their excellent insulation performance, ability to effectively reduce electric shock accidents and short-circuit risks, and improved power supply reliability, they play an irreplaceable role in modern power infrastructure construction. Compared to traditional bare conductors, overhead insulated conductors not only enhance the safety of power transmission but also better adapt to complex urban environments and diverse electricity demands, providing a solid power guarantee for the stable operation of society and economic development.

[0003] In practical use, overhead insulated conductors face complex, variable, and harsh environmental conditions. In terms of the natural environment, there are significant climate differences in different regions, and extreme weather such as strong winds, heavy rain, blizzards, and hail occurs frequently. For example, in coastal areas, strong typhoons are often accompanied by strong winds and heavy rain. The powerful winds will generate huge tensile forces on overhead insulated conductors, subjecting them to stresses far exceeding those of normal operation. Currently, existing overhead insulated conductors on the market have obvious limitations in terms of tensile strength. Most traditional overhead insulated conductors are designed primarily to focus on the conductivity and insulation performance of the conductors, with relatively insufficient consideration given to tensile strength. Their structure is usually relatively simple, mainly consisting of conductive core wires and an outer insulation layer, lacking specialized tensile reinforcement structures or components.

[0004] Therefore, the present invention provides an overhead insulated conductor that is resistant to tension and breakage. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides an overhead insulated conductor that is tensile and fracture resistant, comprising a conductor body, the conductor body being U-shaped, a base being provided on the inner side of the conductor body, positioning plates being rotatably mounted at both ends of the base, the two positioning plates being arranged in parallel, a torsion spring shaft being installed between the positioning plates and the base, and a fixing component A being provided at the end of the positioning plate away from the torsion spring shaft, the fixing component A being used to fix the conductor body.

[0007] Preferably, the fixing component A includes a fixing plate, and a clamping plate A is attached to the outer wall of the fixing plate. The clamping plate A and the fixing plate are fixedly installed on the outer wall of the line by screws.

[0008] Preferably, a receiving plate is attached to the end of the positioning plate away from the torsion spring shaft, a connecting component is provided between the receiving plate and the positioning plate, a mounting base is attached to the top of the receiving plate, the fixing plates are respectively fixedly installed on the outer wall of the mounting base, a set of sliding plates are fixedly installed on the outer wall of the mounting base, the positioning plate and the receiving plate are slidably connected to the corresponding sliding plates, and an elastic component is provided inside the positioning plate.

[0009] Preferably, the elastic component includes an extrusion plate, which is fixedly installed between one end of each set of slide plates. The outer wall of the extrusion plate is slidably connected to the inner wall of the positioning plate, and an elastic element A is fixedly installed between the extrusion plate and the receiving plate.

[0010] Preferably, a fixing component B is provided on each of the two positioning plates on the side away from each other. The structure of the fixing component B is the same as that of the fixing component A. An extension plate is symmetrically fixedly installed on the outer wall of the fixing component B. A slider is fixedly installed on the outer wall of the extension plate. A slide block is symmetrically fixedly installed on the outer wall of each of the two positioning plates. The inner wall of the slide block is slidably connected to the outer wall of the corresponding slider. An elastic supplementing component is provided on the outer side of the base.

[0011] Preferably, the elastic supplementary component includes four clamping plates B, which are respectively fixedly installed on the outer wall of the extension plate. An elastic rope is provided between two corresponding extension plates, and the elastic rope is fixedly connected to the extension plate through the clamping plates B.

[0012] Preferably, the connecting assembly includes connecting blocks symmetrically fixedly installed on the outer wall of the receiving plate, a connecting rod is fixedly installed at the bottom of each connecting block, an elastic ball is fixedly installed at one end of each connecting rod, and connecting seats are symmetrically fixedly installed on the outer wall of the positioning plate, with the connecting rod and the elastic ball slidably connected to the corresponding connecting seat.

[0013] Preferably, a slide rod is slidably installed on the inner wall of the base, a circular plate is fixedly installed at one end of the slide rod, an elastic element B is fixedly installed between the circular plate and the base and on the outside of the slide rod, a positioning ring is fixedly installed on the side of the circular plate away from the elastic element B, and the thread passes through the inside of the positioning ring.

[0014] Preferably, elastic buffer blocks are fixedly installed on the sides of the two positioning plates that are close to each other, and the two elastic buffer blocks abut against each other.

[0015] The beneficial effects of this invention are as follows: 1. The overhead insulated conductor with tensile strength and anti-breakage properties described in this invention, when the conductor is stretched, the tension first acts on the fixing component A. The fixing component A drives the positioning plate to rotate around the torsion spring shaft, causing the two positioning plates to unfold outward. This process realizes the dynamic release of the conductor, dispersing the tension originally concentrated at a certain point to a longer section of the conductor, reducing the tension per unit length of the conductor, and effectively preventing the conductor from breaking due to excessive local stress. The conductor between the two fixing components A is in a relaxed state. When the positioning plates are not unfolded, this relaxed conductor does not bear tension or bears a small tension. When the conductor is stretched and the positioning plates unfold, the relaxed conductor is gradually stretched, absorbing and dispersing the tension, providing additional buffer space for the conductor, and enhancing the overall tensile strength.

[0016] 2. The overhead insulated conductor with tensile strength and anti-breakage properties described in this invention allows for further release of the conductor by the continued movement of the fixing component A when the two positioning plates are fully extended. This process further releases the conductor, disperses the tension, and works in conjunction with the first-stage buffering mechanism of the positioning plates rotating around the torsion spring axis to form a multi-stage buffering system. This significantly enhances the conductor's resistance to tension and effectively prevents damage to the conductor. This graded buffering design enables the conductor to adapt to different levels of tension, effectively protecting the conductor whether in normal working conditions or encountering sudden large tension situations, thus improving the conductor's adaptability and flexibility.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 5As shown in the embodiment of the present invention, an overhead insulated conductor with tensile strength and fracture resistance includes a conductor body 1, which is U-shaped. A base 2 is provided on the inner side of the conductor body 1. Positioning plates 3 are rotatably mounted on both ends of the base 2. The two positioning plates 3 are arranged in parallel. A torsion spring shaft 4 is installed between the positioning plates 3 and the base 2. A fixing component A is provided at the end of the positioning plate 3 away from the torsion spring shaft 4. The fixing component A is used to fix the conductor body 1. The conductor body 1 is fixed at two positions by fixing components A, and the conductor body 1 between the two fixing components A is in a U-shape. The U-shaped distribution is in a relaxed state. The two positioning plates 3 are connected to the base 2 via a torsion spring shaft 4. In their natural state, the two positioning plates 3 are parallel. When the line 1 is pulled, the line 1 will pull the two fixed components A to move. When the fixed components A move, they will drive the corresponding positioning plates 3 to rotate around the torsion spring shaft 4, thereby causing the two positioning plates 3 to unfold outward. When the positioning plates 3 unfold, they will release the line 1. In summary, when the line 1 is pulled, the tension first acts on the fixed components A, and the fixed components A drive the positioning plates 3 to rotate around the torsion spring shaft 4. Rotating around the torsion spring shaft 4 causes the two positioning plates 3 to unfold outwards. This process achieves dynamic release of the line 1, distributing the tension originally concentrated at a certain point to a longer section of the line 1, reducing the tension per unit length of the line 1, and effectively preventing the line 1 from breaking due to excessive local stress. The line 1 between the two fixing components A is in a slack state. When the positioning plates 3 are not unfolded, this slack line 1 does not bear tension or bears a small tension. When the line 1 is stretched and the positioning plates 3 unfold, the slack line 1 is gradually stretched, absorbing and distributing tension. The tension is dispersed, providing additional buffer space for the cable body 1 and enhancing the overall tensile strength. The torsion spring shaft 4 plays an elastic role during the rotation of the positioning plate 3. When the tension of the cable body 1 disappears, the elastic force of the torsion spring shaft 4 will cause the positioning plate 3 to automatically return to a parallel state, allowing the cable body 1 to return to its initial U-shaped relaxed state, preparing for the next possible tension. This achieves the self-resetting and reuse of the structure. Through effective tensile and anti-breakage design, this invention reduces the damage to the cable body 1 caused by tension and greatly extends the service life of the conductor.

[0022] like Figures 3 to 5As shown, the fixing component A includes a fixing plate 5, and a clamping plate A6 is attached to the outer wall of the fixing plate 5. The clamping plate A6 and the fixing plate 5 are fixedly installed on the outer wall of the line body 1 by screws. The line body 1 is placed in the mounting hole of the fixing plate 5 at a suitable position, and then the clamping plate A6 is attached to the fixing plate 5. After that, the clamping plate A6 and the fixing plate 5 are fixed by screws, thus fixing the fixing component A to the line body 1. The entire installation process is clear and does not require complicated tools or professional skills. Ordinary workers can quickly complete the installation after simple training, which greatly improves the installation efficiency and reduces the installation time and labor costs. After the fixing component A is fixed to the line body 1, when the line body 1 is pulled and moved, the line body 1 will drive the fixing component A to move, providing conditions for subsequent buffering work.

[0023] like Figures 1 to 6As shown, a receiving plate 7 is attached to the end of the positioning plate 3 away from the torsion spring shaft 4. A connecting component is provided between the receiving plate 7 and the positioning plate 3. A mounting base 8 is attached to the top of each receiving plate 7. Fixing plates 5 are fixedly installed on the outer wall of the mounting base 8. A set of sliding plates 9 are fixedly installed on the outer wall of each mounting base 8. The positioning plate 3 and the receiving plate 7 are slidably connected to the corresponding sliding plates 9. An elastic component is provided inside each positioning plate 3. When the two positioning plates 3 are extended to be in a straight line with the base 2, this is the maximum extension of the positioning plate 3. At this time, the line 1 between the two fixing components A is still in a slack state. If the positioning plate 3 is extended to its maximum value, it still cannot offset the tension on the line 1. When force is applied, the pulling of the cable 1 causes the two fixed components A to continue moving away from each other. As the fixed components A move, they drive the mounting base 8 to move, which in turn causes the sliding plate 9 to extend outwards towards the positioning plate 3. The elastic component is then compressed and contracts. The continued movement of the fixed components A further releases the cable 1, dispersing the tension. This, combined with the first-stage buffering mechanism of the positioning plate 3 rotating around the torsion spring shaft 4, forms a multi-stage buffering system, greatly enhancing the cable's resistance to tension and effectively preventing damage to the cable 1. The elastic component inside the positioning plate 3 can... The contraction converts tension into stored elastic potential energy. As the tension changes, the elastic component can dynamically adjust its contraction degree, continuously buffering the tension. This elastic buffering method features fast response and good buffering effect, reacting to tension instantaneously, reducing the impact force on line 1, and protecting the structural integrity of line 1. The elastic component not only buffers but also resets the fixed component A through its reverse elastic force. When the tension on line 1 disappears, the elastic potential energy stored in the elastic component is released, pushing the mounting base 8, fixed component A, and other components back to their initial positions. The positioning plate 3 also returns to a parallel state under the action of the torsion spring shaft 4, ensuring the entire... The conductor structure returns to its initial relaxed state, preparing for the next possible tension. This automatic reset function requires no manual intervention, improving the efficiency and reliability of the conductor. The design can automatically adjust the buffering method according to the magnitude of the tension on the conductor 1. When the tension is small, buffering can be achieved simply by rotating the positioning plate 3 around the torsion spring shaft 4. When the tension is large, the second-level buffering mechanism of extending the slide plate 9 and retracting the elastic component is activated. This graded buffering design allows the conductor to adapt to different intensities of tension. Whether in normal working conditions or encountering sudden large tension, it can effectively protect the conductor 1, improving the conductor's adaptability and flexibility.

[0024] like Figures 5 to 6As shown, the elastic component includes a compression plate 10, which is fixedly installed between one end of each set of slide plates 9. The outer wall of the compression plate 10 is slidably connected to the inner wall of the positioning plate 3. An elastic element A11 is fixedly installed between the compression plate 10 and the receiving plate 7. When the slide plate 9 extends to the outside of the positioning plate 3, the slide plate 9 will drive the compression plate 10 to move. When the compression plate 10 moves, it will squeeze the elastic element A11 to make it contract. The reverse elastic force of the elastic element A11 can buffer the tension, effectively reducing the instantaneous impact force on the line 1 and preventing the line 1 from being damaged due to excessive tension. When the tension disappears, the elastic force accumulated by the contraction of the elastic element A11 will be released and thus elongated. When the elastic element A11 elongates, it will push the compression plate 10 to reset, thereby resetting the fixed component A.

[0025] like Figures 1 to 7 As shown, a fixing component B12 is provided on each of the two positioning plates 3 on opposite sides. The structure of the fixing component B12 is the same as that of the fixing component A. An extension plate 13 is symmetrically fixedly installed on the outer wall of the fixing component B12, and a slider 14 is fixedly installed on the outer wall of the extension plate 13. A slide block 15 is symmetrically fixedly installed on the outer wall of each of the two positioning plates 3. The inner wall of the slide block 15 is slidably connected to the outer wall of the corresponding slider 14. An elastic supplementary component is provided on the outer side of the base 2. A fixing component B12 is provided on each side of the two positioning plates 3. The structure of the fixing component B12 is the same as that of the fixing component A. Therefore, the line 1 can be fixed in the same way. When the fixing component B12 fixes the line 1, it will make the line 1 between the fixing component B12 and the fixing component A slack. At the same time, the line 1 between the two fixing components B12 is also slack. This multi-segment slack design provides more buffer space for the line 1. Through the cooperation of the extension plate 13 and the slider 14, the fixing component B12 can slide along the slide block 15. When the skateboard 9 extends outward, the line 1 between the fixed component A and the fixed component B12 will perform a buffering function. When this section of line 1 is taut, the continuous tension of line 1 will pull the two fixed components B12 to move away from each other. When the fixed components B12 move, the line 1 between the two fixed components B12 will continue to be released, thereby further protecting line 1. Each slack section of line 1 can be stretched in sequence, dispersing the tension on line 1 and avoiding breakage of line 1 due to excessive local tension, effectively protecting the structural integrity of line 1. When the two fixed components B12 move away from each other, the elastic supplementary component will be stretched. The elastic supplementary component can supplement the elastic force of elastic element A11. When the elastic force of elastic element A11 weakens due to repeated buffering, the elastic supplementary component can provide additional elastic force to ensure that the entire buffering system always maintains sufficient buffering capacity. This elastic supplementary mechanism enables the buffering system to play a stable and effective role under different working conditions, improving the reliability and adaptability of the buffering system.

[0026] like Figure 3 and Figure 7 As shown, the elastic supplementary component includes four clamping plates B16, which are fixedly installed on the outer wall of the extension plate 13. Elastic ropes 17 are provided between corresponding two extension plates 13, and the elastic ropes 17 are fixedly connected to the extension plates 13 through the clamping plates B16. Through the cooperation between the extension plates 13 and the clamping plates B16, two elastic ropes 17 are connected between the two fixed components B12. During the buffering process, when the two fixed components B12 move away from each other, the elastic ropes 17 are stretched. The elastic ropes 17, through their inherent elasticity, supplement the elastic force of the elastic element A11, ensuring that the entire buffering system always maintains sufficient buffering capacity. The elastic cord 17 effectively disperses the tension on the wire 1. When the tension disappears, the elastic cord 17 contracts, thereby resetting the two fixed components B12 and preparing for the next possible tension. At the same time, the contraction of the elastic cord 17 also helps to restore the elasticity of the entire buffer system, ensuring that it can maintain good buffering performance in subsequent use. The elastic cord 17 and the elastic element A11 work together to form a double buffer protection system, ensuring that the buffer system always maintains sufficient buffering capacity. This double protection mechanism greatly improves the reliability of the buffer system, reduces the probability of failure such as wire 1 breakage due to buffer failure, and extends the service life of the conductor.

[0027] like Figure 4 and Figure 8 As shown, the connecting assembly includes connecting blocks 18 symmetrically fixedly installed on the outer wall of the receiving plate 7. Connecting rods 19 are fixedly installed at the bottom of each connecting block 18, and elastic balls 20 are fixedly installed at one end of each connecting rod 19. Connecting seats 21 are symmetrically fixedly installed on the outer wall of the positioning plate 3. The connecting rods 19 and elastic balls 20 are slidably connected to their corresponding connecting seats 21. The receiving plate 7 is positioned at the end of the positioning plate 3 via the connecting assembly. When the sliding plate 9 extends outward from the positioning plate 3, the compression plate 10 moves accordingly and cooperates with the receiving plate 7 to compress the elastic element A11. When the elastic element A11 is compressed to its limit, it can no longer align with the line. The tension on body 1 is buffered, and body 1 can no longer be released. If the tension on body 1 is still not offset, conventional methods fail, and the tension on body 1 will act on the support plate 7 through the elastic element A11. The tension on the support plate 7 will be transmitted to the elastic ball 20 through the connecting block 18 and the connecting rod 19. The elastic ball 20 will be compressed and slide out from the inside of the connecting seat 21. The support plate 7 can no longer restrict the movement of the slide plate 9 by limiting the elastic element A11, thereby completely releasing body 1. This is to deal with extreme situations and provides a reliable guarantee for dealing with extreme tension situations, effectively preventing body 1 from breaking due to excessive tension.

[0028] like Figures 1 to 2 and Figure 9 As shown, a slide rod 22 is slidably installed on the inner wall of the base 2. A circular plate 23 is fixedly installed at one end of the slide rod 22. An elastic element B24 is fixedly installed between the circular plate 23 and the base 2, and on the outside of the slide rod 22. A positioning ring 25 is fixedly installed on the side of the circular plate 23 away from the elastic element B24. The thread 1 passes through the inside of the positioning ring 25. When the elastic ball 20 slides out from the inside of the connecting seat 21 to completely release the thread 1, the elastic element A11 can no longer play a buffering role. The thread 1 released at the end will pass through the elastic element A11 during the straightening process. The positioning ring 25 and the circular plate 23 compress the elastic element B24. When the elastic element B24 contracts, it can provide final buffering for the line 1. This design constructs a multi-level buffering system, from the initial buffering of the elastic element A11, to the transition after the elastic ball 20 triggers the release mechanism, and then to the final buffering of the elastic element B24. Each level has its specific buffering function and range of action, which can comprehensively meet the needs of the line 1 at different stress stages and ensure that the line 1 can be effectively buffered and protected throughout the entire stress process.

[0029] like Figures 2 to 3 As shown, elastic buffer blocks 26 are fixedly installed on the side of the two positioning plates 3 that are close to each other, and the two elastic buffer blocks 26 abut against each other. In the initial state, the two elastic buffer blocks 26 abut against each other, and the two positioning plates 3 can be kept in a parallel state by the action of the elastic buffer blocks 26. At the same time, when the line body 1 is subjected to reciprocating tension and the two positioning plates 3 are frequently unfolded and reset, the elastic buffer blocks 26 can buffer the impact force generated when the two positioning plates 3 are reset by their own elasticity, so as to prevent the device from being damaged.
