Abstract

This invention relates to an energy-saving and environmentally friendly cable for green buildings, applied in the field of cable-related technology. Through the installation of a self-regulating protective tube, a protective layer can be formed on the exterior of multiple bundled cable bodies. This allows for monitoring of the temperature of multiple cable bodies. When the temperature is too high, the temperature-sensing capsule changes from a solid to a liquid state. Under magnetic attraction, two sensing strips move closer together, causing a significant change in the data on the laser emitter. At this point, the temperature-regulating plate can cool the cable until the temperature is restored, thus achieving automatic temperature control and maintaining it at a relatively low temperature for operation. This effectively ensures stable power transmission from multiple cable bodies, while also protecting the cable bodies from prolonged operation at high temperatures, minimizing the impact on their lifespan and significantly reducing safety hazards. Compared to existing technologies, it has stronger environmental adaptability and better heat dissipation for the cable.

Description

Technical Field

[0001] This invention relates to an energy-saving and environmentally friendly cable, and more particularly to an energy-saving and environmentally friendly cable for green buildings applied in the field of cable-related technologies. Background Technology

[0002] For ease of tidy wiring, cables in green buildings are typically routed uniformly. With a large number of cables clustered together, the cables are prone to overheating during power transmission. This heat accumulation, especially when many cables are clustered together, makes heat dissipation difficult and leads to abnormally high temperatures. This accelerates the aging of the cable sheath, affecting the cable's lifespan. Furthermore, excessive heat accumulation can pose safety hazards such as fires. Current technologies generally address this by improving the sheath material and structure to enhance thermal conductivity and facilitate heat dissipation into the air. Examples include the heat-dissipating charging cable disclosed in Chinese Patent Publication No. CN106887283B and the underground heat-dissipating cable disclosed in Chinese Patent Publication No. CN110400657B.

[0003] However, the above-mentioned heat dissipation method is passive and is greatly affected by the environment. When the ambient temperature is higher than the cable temperature, the material with good thermal conductivity not only does not facilitate heat dissipation, but also causes heat to accumulate in the opposite direction on the cable surface. Furthermore, the heat dissipation effect is more limited, the protection effect on the cable is lower, and the effect on eliminating safety hazards is also poor. Summary of the Invention

[0004] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that cables tend to accumulate heat when laid in clusters, which leads to accelerated aging, affects the service life of the cables, and in severe cases may even pose a fire hazard.

[0005] To address the aforementioned problems, this invention provides an energy-saving and environmentally friendly cable for green buildings, comprising multiple cable bodies. Each cable body has a self-adjusting protective tube fitted to its outer end. A monitoring center is installed on the self-adjusting protective tube. The self-adjusting protective tube includes multiple series-connected rings and multiple long protective tubes connected between adjacent series-connected rings. Each series-connected ring includes a double-ended section and two external connecting pipes connected to the left and right ends of the double-ended section. The external connecting pipes are threaded to the long protective tubes. A temperature-controlled cavity is formed inside the long protective tube. Multiple temperature-regulating plates arranged in a ring array are electrically connected to the inner wall of the temperature-controlled cavity, and the temperature-controlled cavity is saturated with... The tube is filled with deionized water, and a solar panel is fixedly installed on the top of the external connecting tube. The solar panel is electrically connected to the temperature control plate. A temperature sensing hole is also drilled inside the long protective tube. The temperature sensing hole is located outside the temperature control cavity. A temperature sensing unit is set inside the temperature sensing hole. The temperature sensing unit includes two sensing strips that move through the left and right sides of the temperature sensing hole, a temperature-following capsule located between the two sensing strips, and two monitoring tubes that are fixedly embedded at the two ends of the long protective tube. The ends of the monitoring tubes are opposite to the openings of the temperature sensing holes, and a laser emitter is installed inside the monitoring tubes. The laser emitter is coaxially arranged with the sensing strips.

[0006] In the aforementioned energy-saving and environmentally friendly cables for green buildings, the self-regulating protective tube can form a protective layer on the outside of multiple bundled cable bodies. This allows for monitoring of the temperature of multiple cable bodies. When the temperature is too high, it can automatically regulate the temperature to maintain it at a relatively low temperature, thereby effectively ensuring the stable power transmission of multiple cable bodies. At the same time, it effectively protects the cable bodies from prolonged operation at high temperatures, minimizing the impact on their service life and significantly reducing safety hazards.

[0007] As a further improvement of this application, the temperature-regulating capsule is made of an elastic material and is saturated with a hot-melt material inside. The hot-melt material has a hot-melt temperature of not less than 45°C and the temperature-regulating capsule takes the shape of a capsule when not under force.

[0008] As a further improvement of this application, the two monitoring tubes are in contact with the ends of the two sensing strips respectively, and the two sensing strips are simultaneously in contact with the temperature-following capsule. The external connecting tube is made of electromagnetic material, and the double-headed tube is made of magnetic shielding material.

[0009] As a further improvement of this application, the sensing strip includes a limiting section near the monitoring tube, a spherical end near the temperature-following capsule, and a magnetic section fixedly connected between the limiting section and the spherical end. The magnetic section is made of magnetic material, and the magnetic poles of the two magnetic sections are opposite at their respective ends. When energized, the external connecting tube generates a magnetic attraction force on the adjacent magnetic section.

[0010] As a further improvement of this application, the external connecting pipe is fixedly connected to the double-headed tube, the temperature regulating plate is fixed to the inner wall of the temperature control cavity, the temperature regulating plate is a semiconductor cooling plate, and the end of the semiconductor cooling plate facing the axis of the self-adjusting protective tube is the cooling end.

[0011] As a further improvement of this application, the external connecting pipe is connected to the double-headed section pipe via an electric rotating shaft. The inner wall of the temperature control cavity on the side away from the axis of the self-adjusting protective pipe is chiseled with multiple evenly distributed hook-shaped grooves, and the multiple hook-shaped grooves are matched with multiple temperature regulating plates respectively. The two ends of the temperature regulating plates are located in the temperature control cavity and the hook-shaped groove respectively.

[0012] As another improvement of this application, guide rods are fixedly connected to both ends of the temperature regulating plate, and the two guide rods are diagonally distributed. Multiple arc-shaped holes corresponding to multiple guide rods are also drilled at the left and right ends of the long protective tube. The guide rods move through the corresponding arc-shaped holes and are fixedly connected to the external connecting pipe.

[0013] As a further improvement to this application, the temperature control plate includes multiple central shafts, multiple dual temperature control strips respectively fixedly connected between two adjacent central shafts, and two cylindrical surface plates respectively fixedly connected to the ends of the two outermost central shafts. Two guide rods are fixed to the two cylindrical surface plates respectively. The dual temperature control strips are semiconductor cooling plates, and the central shafts are made of elastic material.

[0014] As a further improvement to this application, the two external connecting pipes corresponding to the long protective pipe rotate in the same direction each time, and the rotation directions of two adjacent rotations are opposite, and the angle of each rotation is not greater than the span of the arc hole.

[0015] In summary, by setting up a self-regulating protective tube, a protective layer can be formed on the outside of multiple bundled cable bodies. The temperature of multiple cable bodies can be monitored. When the temperature is too high, the temperature-sensing capsule will change from a solid to a liquid state. Under the action of magnetic attraction, the two sensing strips will move closer to each other, causing a significant change in the data on the laser emitter. At this time, the temperature-regulating plate can cool down until the temperature is restored, thereby achieving automatic temperature regulation and maintaining it in a relatively low temperature state for operation. This effectively ensures the stable power transmission of multiple cable bodies, while effectively protecting the cable bodies from prolonged operation at high temperatures, thus minimizing the impact on their service life and significantly reducing safety hazards. Compared with existing technologies, it has stronger environmental adaptability and better heat dissipation for the cables. Attached Figure Description

Detailed Implementation

[0031] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0032] First implementation method:

[0033] Figure 1-2 This invention discloses an energy-saving and environmentally friendly cable for green buildings, comprising multiple cable bodies 1, each cable body 1 having a self-adjusting protective tube 2 fitted at its outer end. The self-adjusting protective tube 2 is equipped with a monitoring center. The self-adjusting protective tube 2 includes multiple series rings and multiple long protective tubes 23 respectively connected between two adjacent series rings. Each series ring includes a double-ended section tube 21 and two external connecting tubes 22 respectively connected to the left and right ends of the double-ended section tube 21. The external connecting tubes 22 are threadedly connected to the long protective tubes 23.

[0034] Figure 3-4 As shown, a temperature control cavity 202 is carved inside the long protective tube 23. Multiple temperature-regulating plates 6 arranged in a ring array are electrically connected to the inner wall of the temperature control cavity 202. The temperature control cavity 202 is saturated with deionized water. A solar cell 101 is fixedly installed on the top of the outer connecting tube 22. The solar cell 101 is electrically connected to the temperature-regulating plates 6 and supplies power to the temperature-regulating plates 6, enabling them to turn on for cooling, thereby regulating the external temperature of the cable body 1. A temperature-sensing elongated hole 201 is also carved inside the long protective tube 23, located outside the temperature control cavity 202. Figure 5 The temperature sensing elongated hole 201 is equipped with a temperature sensing unit. The temperature sensing unit includes two sensing strips 3 that move through the left and right sides of the temperature sensing elongated hole 201 respectively, a temperature-following capsule 5 located between the two sensing strips 3, and two monitoring tubes 4 that are fixedly embedded at the two ends of the long protective tube 23 respectively. The ends of the monitoring tubes 4 are opposite to the opening of the temperature sensing elongated hole 201.

[0035] like Figure 8 The sensing strip 3 includes a limiting section 31 near the monitoring tube 4, a spherical end 33 near the temperature-following capsule 5, and a magnetic section 32 fixedly connected between the limiting section 31 and the spherical end 33. The magnetic section 32 is made of magnetic material, and the magnetic poles of the two magnetic sections 32 are opposite at the ends that are close to each other, so that there is a magnetic attraction between the two sensing strips 3.

[0036] like Figure 7 In the diagram, 'a' represents the laser beam emitted by laser emitter 401. Laser emitter 401 is installed inside monitoring tube 4, and it is coaxially arranged with sensing strip 3. When there is no high temperature, the temperature-sensing capsule 5 is in a normal capsule state. At this time, sensing strip 3 is in contact with the end of monitoring tube 4, or there is only a very small gap between them. At this time, the distance data acquired by laser emitter 401 is minimal. When abnormally high temperatures occur, such as... Figure 6As the thermoplastic material inside the temperature-regulating capsule 5 gradually dissolves, it transforms from a solid to a liquid state. At this time, under the action of magnetic force, the two sensing strips 3 attract each other and stick to the temperature-regulating capsule 5, allowing the temperature-regulating capsule 5 to deform in accordance with the direction of the force, causing the two sensing strips 3 to gradually approach each other. At this time, the distance between the laser emitter 401 and the end of the sensing strip 3 increases, causing a significant change in the data on the laser emitter 401. At this point, it can be determined that multiple cable bodies 1 have experienced abnormal temperature increases. After the monitoring center receives this signal, it can control the temperature regulating plate 6 to start cooling, gradually lowering the temperature of the deionized water, thereby achieving the effect of cooling multiple cable bodies 1. This prevents the cable bodies 1 with clustered wiring from operating at high temperatures for extended periods, allowing them to operate at a relatively suitable temperature. This effectively protects the cable bodies 1 from accelerated aging due to high temperatures, thus effectively ensuring their service life and reducing the safety hazards caused by overheating.

[0037] In the aforementioned energy-saving and environmentally friendly cables for green buildings, the self-regulating protective tube 2 forms a protective layer on the outside of multiple bundled cable bodies 1, which can monitor the temperature of multiple cable bodies 1. When the temperature is too high, it can automatically regulate the temperature to maintain it at a relatively low temperature, thereby effectively ensuring the stable power transmission of multiple cable bodies 1. At the same time, it effectively protects the cable bodies 1 from long-term operation at high temperatures, making their service life less affected and significantly reducing safety hazards.

[0038] The temperature-regulating capsule 5 is made of elastic material and is saturated with hot-melt material. The hot-melt material has a melting temperature of not less than 45°C. When the temperature-regulating capsule 5 is not under force, it takes the shape of a capsule. When the temperature rises to above 35°C, it can trigger temperature regulation to lower the temperature to below 45°C, thus ensuring stable power transmission.

[0039] Two monitoring tubes 4 are in contact with the ends of two sensing strips 3 respectively, and the two sensing strips 3 are simultaneously in contact with the temperature-following capsule 5. The external connecting tube 22 is made of electromagnetic material, and the double-headed tube 21 is made of magnetic shielding material. When the external connecting tube 22 is energized, it generates a magnetic attraction force on the adjacent magnetic segment 32. Each time temperature regulation is started, the two external connecting tubes 22 corresponding to the two sensing strips 3 can be energized first, so that they attract their corresponding sensing strips 3, and then the two sensing strips 3 move away from each other until they contact the corresponding monitoring tube 4. At this time, the temperature-following capsule 5 returns to its capsule shape. As the temperature is regulated, it gradually hardens, so that after each regulation, the sensing strips 3 and the temperature-following capsule 5 can be reset for subsequent monitoring.

[0040] In this embodiment, the external connecting pipe 22 is fixedly connected to the double-headed section pipe 21, and the temperature regulating plate 6 is fixed to the inner wall of the temperature control cavity 202. The temperature regulating plate 6 is a semiconductor cooling plate, and the end of the semiconductor cooling plate facing the axis of the self-adjusting protective pipe 2 is the cooling end, so that it can cool down the multiple cable bodies 1 bundled together after being powered on.

[0041] In summary, by setting up the self-regulating protective tube 2, a protective layer can be formed on the outside of multiple bundled cable bodies 1, and the temperature of multiple cable bodies 1 can be monitored. When the temperature is too high, the temperature-sensing capsule 5 will change from solid to liquid. Under the action of magnetic attraction, the two sensing strips 3 will move closer to each other, which will cause a significant change in the data on the laser emitter 401. At this time, the temperature regulating plate 6 can cool down until the temperature is restored, thereby realizing automatic temperature regulation and maintaining it in a relatively low temperature state for operation. This effectively ensures the stable transmission of power from multiple cable bodies 1, while effectively protecting the cable bodies 1 from long-term operation at high temperatures, making their service life less affected, and significantly reducing safety hazards. Compared with existing technologies, it has stronger environmental adaptability and better heat dissipation effect for cables.

[0042] Second implementation method:

[0043] This embodiment further adjusts the temperature control plate 6 based on the first embodiment, while the rest remains the same as the first embodiment.

[0044] Figure 9-10 As shown, the external connecting pipe 22 is connected to the double-headed section pipe 21 via an electric rotating shaft. Multiple evenly distributed hook-shaped grooves 203 are carved into the inner wall of the temperature control cavity 202 on the side away from the axis of the self-adjusting protective pipe 2. The corners of the openings of the hook-shaped grooves 203 are arc-shaped, and each hook-shaped groove 203 is matched with a multiple temperature regulating plate 6. The two ends of the temperature regulating plate 6 are located in the temperature control cavity 202 and the hook-shaped grooves 203, respectively. Figure 10 and Figure 13 In the middle, the temperature regulating plate 6 has a cooling end on one end and a heating end on the other end. When adjusting the temperature, the external connecting pipe 22 can be rotated by the electric rotating shaft, which in turn drives the temperature regulating plate 6 to move in and out of the long protective pipe 23, thereby realizing the flipping of the temperature regulating plate 6. This allows the multiple cable bodies 1 inside the self-regulating protective pipe 2 to be cooled or heated, thus adapting to the effects of low winter temperature or high summer temperature on the multiple cable bodies 1.

[0045] like Figure 9 The temperature regulating plate 6 has guide rods 601 fixedly connected to both ends, and the two guide rods 601 are diagonally distributed, such as... Figure 11 The left and right ends of the long protective pipe 23 are also drilled with multiple arc-shaped holes 204 corresponding to multiple guide rods 601. The guide rods 601 move through the corresponding arc-shaped holes 204 and are fixedly connected to the external connecting pipe 22, such as... Figure 12 The temperature regulating plate 6 includes multiple central shafts 62, multiple dual temperature control strips 61 respectively fixedly connected between two adjacent central shafts 62, and two cylindrical surface plates 63 respectively fixedly connected to the ends of the two outermost central shafts 62. Two guide rods 601 are fixed to the two cylindrical surface plates 63 respectively. The dual temperature control strips 61 are semiconductor cooling plates, and the central shafts 62 are made of elastic material, allowing adjacent dual temperature control strips 61 to undergo bending and other angle changes, thereby adapting to the entry and exit of the long protective tube 23. This allows the self-adjusting protective tube 2 to not only regulate the cooling of multiple cable bodies 1 under high temperature abnormalities, but also to regulate the heating under low temperature conditions.

[0046] The two external connecting pipes 22 corresponding to the long protective tube 23 rotate in the same direction each time, and the rotation directions of two adjacent rotations are opposite. The angle of each rotation is not greater than the span of the arc hole 204, which effectively ensures the stable flipping of multiple temperature regulating plates 6.

[0047] In this embodiment, compared to the first embodiment, low temperature control can also be performed, making the cable more adaptable and able to adapt to more extreme environments.

[0048] The third implementation method:

[0049] The temperature-following capsule 5 can also be made of a two-way temperature memory alloy. In this case, the temperature-following capsule 5 is originally in a straight line shape, and its critical temperature is set to 35-45℃. When it is above the critical temperature, it shortens and becomes a spiral spring tube shape, which can also cause the data of the laser emitter 401 to change. Then, the temperature regulating plate 6 can be controlled to work and cool down until the temperature of multiple cable bodies 1 drops. When it is below the critical temperature, it gradually elongates and returns to a straight line shape, so that the sensing strip 3 contacts the monitoring tube 4 again, so that the data of the laser emitter 401 is minimized. That is, the sensing strip 3 returns to the original shape of the temperature-following capsule 5, and the temperature of the cable body 1 can continue to be monitored. At this time, the temperature regulating plate 6 can be controlled to cut off the power and stop the cooling.

[0050] Accordingly, in this embodiment, the sensing strip 3 is not set as a three-section structure, but is set as a whole non-magnetic structure. Similarly, the external connecting tube 22 does not need to be made of electromagnetic material, but can be made of ordinary hard material.

[0051] In practice, the appropriate implementation method can be selected from the three implementation methods mentioned above, based on actual needs.

[0052] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Various changes made within the knowledge of those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
