Description

Technical Field

[0001] This invention relates to the field of overhead line technology, specifically to a safe overhead line that prevents icing. Background Technology

[0002] Overhead lines refer to power transmission / distribution lines that use poles, insulators, and other supporting structures to erect conductors in the air. Their core function is to achieve long-distance power transmission or regional power distribution. They are the most basic and widely used form of power transmission in the power system. Overhead lines are the most basic and economical form of power transmission in the power system. Through the core combination of "conductor-insulator-pole-fittings", they realize the transmission of power from power plants to users. Their core value lies in low cost and convenient construction and maintenance, making them suitable for most scenarios. For this purpose, a Chinese patent discloses a cable with anti-icing function, application number CN201810698819.8. The cable in this patent has the functions of preventing icing and de-icing.

[0003] However, due to the limitations of its own structure, overhead lines can only be passively protected against freezing and de-iced through the external protective layer material during use. This leads to the accumulation of ice on the outside of the overhead line during use, which reduces the overall antifreeze performance and service life of the overhead line. Summary of the Invention

[0004] This invention provides a safe overhead power line that prevents icing, which can effectively solve the problem mentioned in the background art that overhead power lines are limited by their own structure during use, and can only be passively protected against freezing and de-iced by the external protective layer material. This leads to the accumulation of ice on the outside of the overhead power line during use, which reduces the overall antifreeze performance of the overhead power line and shortens its service life.

[0006] The limiting bundle sleeve is equipped with a temperature-sensing deformation adjustment mechanism. The temperature-sensing deformation adjustment mechanism adjusts the shape of the overhead line according to the temperature difference between the inside and outside, and changes its heat dissipation method during the change of the shape of the overhead line to prevent icing from occurring on the outside of the overhead line.

[0026] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0027] 1. A temperature-sensing deformation adjustment mechanism is installed. Through the cooperation of the various components inside the temperature-sensing deformation adjustment mechanism, the anti-freezing and de-icing process of the overhead line in the cold environment is optimized. By using the deformable design of each structure on the deformable installation strip, the temperature difference between the inside and outside of the overhead line is used to drive the thermo-bimetallic strip to control the active deformation of the overhead line. The active deformation of the overhead line breaks and removes the ice shell that has initially condensed on its outside. In this way, the deformation of the overhead line shape achieves de-icing, thereby preventing the accumulation of ice on the outside of the overhead line from the source. At the same time, the triangular structure formed by the deformation of the overhead line changes the stress on the snow and ice shell at the top of the overhead line, making it easier for the snow and ice shell at the top of the overhead line to fall off, thus preventing the accumulation of snow on the top of the overhead line during use.

[0028] Meanwhile, the flexible deformable structure spliced ​​on both sides of the support deformation strip ensures that all components inside the overhead line can deform synchronously during the deformation of the driving hot bimetallic sheet. At the same time, the changes in the telescopic buffer airbag and its side components change the overall heat dissipation path of the overhead line. Furthermore, by taking advantage of the uneven heat dissipation characteristics on the outside of the overhead line, the local high temperature on the outside of the overhead line is used to locally melt the ice shell covering the outside of the overhead line. This effectively uses heat to destroy the stability of the ice shell structure on the outside of the overhead line, making it easier for the ice shell covering the outside of the overhead line to fall off under the action of gravity, further improving the antifreeze and de-icing effect of the overhead line.

[0029] Furthermore, by utilizing the cooperation between the telescopic fluid-conducting bladder and the arc-shaped telescopic elastic bladder, when the shape of the driving heat bimetallic strip and the overhead line changes, the heat-conducting oil inside the telescopic fluid-conducting bladder and the arc-shaped telescopic elastic bladder is transferred to fill the gaps on the outside of the internal insulation layer. This ensures that the internal structure of the overhead line remains unchanged during the deformation and de-icing process, effectively preventing abnormal torsion and bending of the internal power supply conductors that would affect the normal use of the overhead line. This further improves the overall stability of the overhead line and extends its service life.

[0030] 2. An internal dynamic telescopic stabilization mechanism is set up. Through the cooperation between the various components of the internal dynamic telescopic stabilization mechanism, the adjustment method during the de-icing process of the overhead line is optimized. By utilizing the movable characteristics of the telescopic rolling ball, the kinetic energy of the overhead line during the vibration process can be consumed by the local reciprocating rolling of the telescopic rolling ball. The impact process of the telescopic rolling ball is buffered by the telescopic guide plate and the buffer spring. The kinetic energy of the telescopic rolling ball movement cancels out the kinetic energy of the overhead line vibration, ensuring that the vibration of the overhead line can be quickly recovered during the de-icing process, effectively improving the stability of the overhead line.

[0031] Meanwhile, by utilizing the cooperation between the snap-fit ​​mounting ring and the positioning magnetic block, and through the magnetic attraction between the positioning magnetic block and the telescopic rolling ball, the overhead line can be quickly reset after it has regained stability. At the same time, the arc splicing structure design of the snap-fit ​​mounting ring effectively improves the overall structural strength of the overhead line.

[0032] In summary, by coordinating the components within the temperature-sensing deformation adjustment mechanism and the internal dynamic telescopic stabilization mechanism, and utilizing the temperature distribution characteristics of overhead lines operating in cold environments, the overhead lines can actively deform during de-icing. This deformation adjusts the heat dissipation method of the overhead lines, thereby actively disrupting the integrity of the ice shell structure on their outer surface. This allows the ice shell on the outer surface of the overhead lines to quickly separate and fall off, effectively improving the overall anti-freezing and de-icing effect of the overhead lines. Simultaneously, the movable nature of the telescopic rolling balls inside the triangular mounting strip transfers and dissipates the kinetic energy generated during the shaking of the overhead lines, ensuring stability during de-icing and further enhancing the overall stability and extending the service life of the overhead lines.

[0048] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0049] Example: Figure 1-10 As shown, the present invention provides a technical solution, a safe overhead line for preventing icing, including an internal power supply conductor 1, an internal insulation layer 2 tightly wrapped around the outside of the internal power supply conductor 1, and a limit bundle sleeve 3 wrapped around the outside of the internal insulation layer 2.

[0050] The limiting bundle sleeve 3 is equipped with a temperature-sensing deformation adjustment mechanism 4. The temperature-sensing deformation adjustment mechanism 4 adjusts the shape of the overhead line according to the temperature difference between the inside and outside, and changes its heat dissipation method during the change of the shape of the overhead line to prevent icing from occurring on the outside of the overhead line.

[0051] The temperature-sensing deformation adjustment mechanism 4 includes a support deformation rubber strip 401, an internal support cable 402, a thermally conductive silicone inner sheet 403, a deformation mounting soft strip 404, an outer rectangular mounting groove 405, a central fixed rectangular strip 406, a driving heat bimetallic sheet 407, an elastic silicone thermally conductive sheet 408, an internal reinforcing metal wire 409, a telescopic porous silicone sheet 410, a telescopic buffer airbag 411, a flexible connecting rubber strip 412, a rubber mounting sleeve 413, a telescopic fluid-guiding round bag 414, an arc-shaped telescopic elastic bag 415, an internal support sponge strip 416, and an outer rubber protective layer 417.

[0052] The outer side of the limiting strapping sleeve 3 is evenly covered with support deformation rubber strips 401 at equal intervals along the circumference. An internal support cable 402 is inserted and installed in the middle of the outer side of the support deformation rubber strip 401. A thermally conductive silicone inner sheet 403 is attached to the outer side of the limiting strapping sleeve 3 at the position corresponding to the side of the support deformation rubber strip 401.

[0053] A deformable mounting strip 404 is inserted and installed in the middle of the inner side of the support deformable rubber strip 401. An outer rectangular mounting groove 405 is evenly and equidistantly opened on one side of the deformable mounting strip 404 along the axial direction. A central fixed rectangular strip 406 is fixedly connected to the middle of one side of the outer rectangular mounting groove 405. A driving heat bimetallic strip 407 is inserted and installed in the middle of one end of the central fixed rectangular strip 406. The driving heat bimetallic strip 407 passes through the interior of the central fixed rectangular strip 406. The driving heat bimetallic strip 407 and the internal support cable 402 are positioned corresponding to each other. An arc-shaped groove is opened in the middle of both ends of the driving heat bimetallic strip 407.

[0054] Elastic silicone heat-conducting sheets 408 are bonded to both sides of the outer side of the support deformable rubber strip 401. An internal reinforcing metal wire 409 is embedded in the middle of the outer side of the elastic silicone heat-conducting sheet 408. The outer side of the internal reinforcing metal wire 409 is flush with the outer side of the elastic silicone heat-conducting sheet 408. The outer arc surface of the elastic silicone heat-conducting sheet 408 is flush with the outer arc surface of the support deformable rubber strip 401. The heat-conducting silicone inner sheet 403 is tightly attached to the limiting strap sleeve 3 and the elastic silicone heat-conducting sheet 408 respectively. The positions of the heat-conducting silicone inner sheet 403 and the internal reinforcing metal wire 409 correspond to each other.

[0055] On both sides of the support deformable rubber strip 401, at the outer position of the elastic silicone heat-conducting sheet 408, there are telescopic porous silicone sheets 410 arranged in the circumferential direction. A telescopic buffer airbag 411 is snapped into the gap between the two telescopic porous silicone sheets 410. The telescopic buffer airbag 411 corresponds to the internal reinforcing metal wire 409. The outer arc surface of the telescopic buffer airbag 411 is flush with the outer arc surface of the telescopic porous silicone sheet 410.

[0056] A flexible connecting strip 412 is inserted into the inner part of the limiting strap sleeve 3, corresponding to the deformable mounting strip 404. A rubber mounting sleeve 413 is equidistantly inserted into the inner part of the flexible connecting strip 412, corresponding to the gap on the side of the inner insulation layer 2. A telescopic fluid-guiding bladder 414 is inserted into the inner part of the rubber mounting sleeve 413. Arc-shaped telescopic elastic bladders 415 are fixedly connected to both sides of the telescopic fluid-guiding bladder 414, corresponding to the outer parts of the rubber mounting sleeve 413. The telescopic fluid-guiding bladder 414 contains… The inner support sponge strip 416 is filled with a flexible connecting strip 412 that is tightly fitted to the outer side of the rubber mounting sleeve 413. The inner cavities of the telescopic fluid-conducting round bladder 414 and the arc-shaped telescopic elastic bladder 415 are interconnected, and both the inner cavities of the telescopic fluid-conducting round bladder 414 and the arc-shaped telescopic elastic bladder 415 are filled with heat-conducting oil. The rubber mounting sleeves 413 are connected to each other by connecting auxiliary strips. There is a gap between the outer arc surface of the arc-shaped telescopic elastic bladder 415 and the inner insulation layer 2 and the limiting binding sleeve 3.

[0057] The outer side of the support deformation strip 401 is tightly covered with an external rubber protective layer 417. Through the cooperation between the various components inside the temperature-sensing deformation adjustment mechanism 4, the antifreeze and de-icing process of the overhead line in the cold environment is optimized. Through the deformable design of each structure on the deformable installation strip 404, the temperature difference between the inside and outside of the overhead line is used to drive the hot bimetallic strip 407 to control the overhead line to actively deform. The active deformation of the overhead line breaks and removes the ice shell that has initially condensed on its outside. The deformation of the overhead line shape achieves de-icing, thereby preventing the accumulation of ice on the outside of the overhead line from the source. At the same time, the triangular structure formed by the deformation of the overhead line changes the stress on the snow and ice shell at the top of the overhead line, making it easier for the snow and ice shell at the top of the overhead line to fall off, thus preventing the accumulation of snow at the top of the overhead line during use.

[0058] Meanwhile, the flexible deformable structure spliced ​​on both sides of the support deformation strip 401 ensures that all components inside the overhead line can deform synchronously during the deformation of the driving hot bimetallic strip 407. At the same time, the changes in the telescopic buffer airbag 411 and its side components change the overall heat dissipation path of the overhead line. Then, by taking advantage of the uneven heat dissipation characteristics on the outside of the overhead line, the local high temperature on the outside of the overhead line is used to locally melt the ice shell covering the outside of the overhead line. This effectively uses heat to destroy the stability of the ice shell structure on the outside of the overhead line, making it easier for the ice shell covering the outside of the overhead line to fall off under the action of gravity, further improving the antifreeze and de-icing effect of the overhead line.

[0059] Furthermore, by utilizing the cooperation between the telescopic fluid-conducting bladder 414 and the arc-shaped telescopic elastic bladder 415, when the shape of the driving heat bimetallic strip 407 and the overhead line changes, the heat-conducting oil inside the telescopic fluid-conducting bladder 414 and the arc-shaped telescopic elastic bladder 415 is transferred to fill the gap on the outside of the inner insulation layer 2. This ensures that the internal structure of the overhead line remains unchanged during the deformation and de-icing process, effectively preventing abnormal torsion and bending of the internal power supply conductor 1 from affecting the normal use of the overhead line, further improving the overall stability of the overhead line structure, and extending the service life of the overhead line.

[0060] An internal dynamic telescopic stabilizing mechanism 5 is provided in the middle of the inner side of the limiting bundle sleeve 3. The internal dynamic telescopic stabilizing mechanism 5 is used to convert the kinetic energy during the swing of the overhead line to ensure the stability of the overhead line during use.

[0061] The internal dynamic telescopic stabilizing mechanism 5 includes a connecting triangular rubber strip 501, a triangular mounting strip 502, an internal isolation bladder 503, an elastic support guide 504, a telescopic guide plate 505, a buffer spring 506, a telescopic rolling ball 507, a snap-fit ​​mounting ring 508, and a positioning adsorption magnetic block 509.

[0062] The inner side of the limiting strap sleeve 3 is evenly provided with connecting triangular rubber strips 501 at equal intervals. The end of the connecting triangular rubber strip 501 is fixedly connected with a triangular mounting strip 502. An internal isolation bladder 503 is snapped into the triangular mounting strip 502. An elastic support guide 504 is snapped into the internal isolation bladder 503.

[0063] Both ends of the elastic support guide 504 are provided with telescopic guide plates 505. A buffer spring 506 is fixedly connected to the middle of one side of the telescopic guide plate 505. A telescopic rolling ball 507 is movably engaged in the middle of the inner side of the elastic support guide 504. The outer arc surfaces of the connecting triangular rubber strip 501 and the triangular mounting strip 502 are tightly slidably attached to the outer side of the inner insulation layer 2. The end of the buffer spring 506 corresponds to the telescopic rolling ball 507.

[0064] An engagement ring 508 is snapped onto the outer side of the outer rubber protective layer 417. A positioning magnetic block 509 is snapped onto the middle of the side of the engagement ring 508. The outer side of the telescopic ball bearing 507 is tightly slidably attached to the inner arc surface of the elastic support guide 504. The positioning magnetic block 509 and the telescopic ball bearing 507 correspond to each other, and the telescopic ball bearing 507 is attracted by the magnetic force of the positioning magnetic block 509. Through the mutual cooperation between the components inside the internal dynamic telescopic stabilizing mechanism 5, the adjustment method during the de-icing process of the overhead line is optimized. Utilizing the movable characteristics of the telescopic ball bearing 507, the kinetic energy during the vibration of the overhead line can be consumed by the local reciprocating rolling of the telescopic ball bearing 507. The impact process of the telescopic ball bearing 507 is buffered by the telescopic guide plate 505 and the buffer spring 506. The kinetic energy of the telescopic ball bearing 507 is offset by the kinetic energy of the vibration of the overhead line, ensuring that the vibration of the overhead line during the de-icing process can be quickly recovered, effectively improving the stability of the overhead line.

[0065] Meanwhile, by utilizing the cooperation between the snap-fit ​​mounting ring 508 and the positioning magnetic block 509, and through the magnetic attraction between the positioning magnetic block 509 and the telescopic rolling ball 507, the overhead line can be quickly reset after it has regained stability. At the same time, the arc splicing structure design of the snap-fit ​​mounting ring 508 effectively improves the overall structural strength of the overhead line.

[0066] The working principle and usage process of this invention: During the cable production process, the connecting triangular rubber strip 501 and the components connected thereon need to be externally assembled. First, the telescopic guide plate 505 and the buffer spring 506 are connected to the end of the elastic support guide 504, and the telescopic rolling ball 507 is movably snapped into the inside of the elastic support guide 504. Then, the elastic support guide 504 is inserted into the inside of the internal isolation bladder 503. Next, the internal isolation bladder 503 is inserted into the inside of the internal isolation bladder 503. Finally, the triangular mounting strips 502 are connected by the connecting triangular rubber strip 501 to complete the production of the cable's internal core material. During the cable production process, the internal power supply conductor 1 and the internal insulation layer 2 are arranged and wrapped around the outside of the connecting triangular rubber strip 501 and the triangular mounting strip 502 to complete the arrangement of the components inside the cable.

[0067] In practical applications, when an overhead line is required, the internal power supply conductor 1 is first connected to a suitable location for power supply. Then, the outer side of the internal power supply conductor 1 is insulated and protected by the internal insulation layer 2. The multiple internal power supply conductors 1 are then bundled and limited by the limiting bundle sleeve 3. The components are installed on the outside of the limiting bundle sleeve 3 by the supporting deformable rubber strip 401 in conjunction with the elastic silicone heat-conducting sheet 408 and the telescopic porous silicone sheet 410. The structural strength of the supporting deformable rubber strip 401 is enhanced by the internal support cable 402. At the same time, the heat dissipation path inside the overhead line is changed by the internal reinforcing metal wire 409.

[0068] When the overhead line is used in low temperature rain and snow weather, the internal power supply conductor 1 naturally heats up during the power transmission process. The heat-conducting oil inside the telescopic fluid-conducting round bladder 414 and the arc-shaped telescopic elastic bladder 415 shrinks in volume in the low temperature environment, which makes the gap between the outer arc surface of the arc-shaped telescopic elastic bladder 415 and the limiting bundle sleeve 3 expand as a whole. Even after the arc-shaped telescopic elastic bladder 415 absorbs heat and expands, it still cannot expand outward and contact the limiting bundle sleeve 3, so as to reduce the overall heat dissipation performance of the overhead line. This ensures that the internal area of ​​the overhead line can maintain a high temperature in the low temperature environment, and ensures that the driving heat bimetallic strip 407 can absorb enough heat and deform.

[0069] This causes a large temperature difference between the inside and outside of the overhead line. The driving heat bimetallic strip 407 is installed on the side of the deformable mounting strip 404 through the outer rectangular mounting groove 405 and the central fixed rectangular strip 406. Then, the deformable mounting strip 404 installs each component into the support deformable rubber strip 401. When the driving heat bimetallic strip 407 is affected by the heat inside the overhead line, due to the different expansion coefficients of the inner and outer metals of the driving heat bimetallic strip 407, the driving heat bimetallic strip 407 gradually bends towards the outside of the overhead line. During the bending process of the driving heat bimetallic strip 407, it drives the support deformable rubber strip 401 to deform in the same way. Thus, the driving heat bimetallic strip 407 actively deforms the outer contour of the overhead line.

[0070] By driving the bimetallic strip 407 to bend and deform, the outer diameter and shape of the overhead line are actively changed, so as to physically break apart the small amount of ice shell frozen on the outside of the overhead line, thus preventing the accumulation of ice shell on the outside of the overhead line. At the same time, since the two ends of the bimetallic strip 407 will be far away from the center area of ​​the overhead line after bending, the temperature of the bimetallic strip 407 will drop, so that the bimetallic strip 407 will gradually return to its original position after cooling down. Meanwhile, the load of the overhead line will also change at different times, so that the bimetallic strip 407 will be bent and deformed alternately during normal operation, making the overhead line deform into a triangular structure with a smaller top and a larger bottom. This allows the ice shell on the outside of the overhead line to be broken off and removed in the initial stage of formation, thereby improving the overall antifreeze performance of the overhead line.

[0071] While the driving bimetallic strip 407 causes the supporting deformable rubber strip 401 and the outer rubber protective layer 417 to deform, the deformation of the outer rubber protective layer 417 will simultaneously squeeze the telescopic buffer airbag 411 and the telescopic porous silicone sheet 410 inward. After the telescopic buffer airbag 411 is flattened, the gap between the outer rubber protective layer 417 and the inner reinforcing metal wire 409 is greatly reduced. This allows the heat inside the overhead line to be directly transferred to the outside of the outer rubber protective layer 417 through the thermally conductive silicone inner sheet 403 and the inner reinforcing metal wire 409, thereby changing the overall heat dissipation path of the overhead line. When the driving bimetallic strip 407 bends, the heat is mainly concentrated in the linear area on the side of the inner reinforcing metal wire 409. This utilizes the heat inside the overhead line to locally melt the ice shell formed on the outside of the overhead line, thereby destroying the integrity of the side structure of the overhead line and making it easier for the ice shell on the outside of the overhead line to fall off.

[0072] Furthermore, the rubber mounting sleeve 413 and its external components are installed into the limiting bundle sleeve 3 through the flexible connecting strip 412. During the bending process of the driving hot bimetallic strip 407, the rubber mounting sleeve 413 and the telescopic fluid guiding bladder 414 are also squeezed, so that the heat-conducting oil inside the rubber mounting sleeve 413 is squeezed into the arc-shaped telescopic elastic bladder 415, thereby causing the arc-shaped telescopic elastic bladder 415 to expand and fill the gap between the internal insulation layers 2. This ensures that the internal power supply conductor 1 will not be squeezed and deformed during the deformation of the driving hot bimetallic strip 407, and ensures that the internal structure of the overhead line remains stable during the de-icing process, thereby improving the overall stability of the overhead line structure.

[0073] When the ice shell on the outside of the overhead line falls off, it will cause a sudden change in the weight of the overhead line, causing the overhead line to shake rapidly for a short time due to the sudden change in tension. When it is necessary to maintain the overall stability of the overhead line, the triangular installation strip 502 is installed into the limiting bundle sleeve 3 by connecting the triangular rubber strip 501, and then the elastic support guide 504 and its internal components are installed into the center of the overhead line by the internal isolation bladder 503.

[0074] When the overhead line vibrates, the telescopic ball bearing 507 will slide rapidly along the inside of the elastic support guide 504. During the sliding process, the telescopic ball bearing 507 will collide with the buffer spring 506. The extension and retraction of the buffer spring 506 will consume the kinetic energy of the telescopic ball bearing 507 and cancel out the kinetic energy of the overhead line during the swing. This allows the overhead line to quickly return to stability after the vibration. At the same time, the positioning magnetic block 509 is installed on the outside of the overhead line by the snap-fit ​​mounting ring 508. The positioning magnetic block 509 will attract and position the telescopic ball bearing 507 so that the telescopic ball bearing 507 will reset after the overhead line returns to stability.
