Description

Technical Field

[0001] The invention relates to a cable, in particular to an ultraviolet-resistant cable for photovoltaic power generation applied in the cable field. Background Art

[0002] With the adjustment of the global energy structure and the rapid development of renewable energy, photovoltaic power generation technology has been widely used and popularized due to its clean, efficient and sustainable characteristics. In the photovoltaic power generation system, the cable is the link between the solar panels and the inverter, energy storage equipment and other key components. Its performance will directly affect the efficiency and stability of the photovoltaic power generation system.

[0003] Since photovoltaic power generation systems are usually set up in the open outdoors, part of the cable body is exposed to the sun for a long time and is directly exposed to ultraviolet rays. Ultraviolet rays will accelerate the aging of the cable, causing the insulation performance and service life of the cable to be significantly reduced, which will lead to uneven aging of the cable, that is, the aging degree of the part of the cable body exposed to the sun will be much higher than that of the part of the cable body not exposed to the sun.

[0004] This uneven aging phenomenon will cause great trouble to the maintenance and replacement of cables. When the part of the cable body that has been exposed to the sun for a long time is seriously aged and needs to be replaced, since the other part of the cable body is still within its service life, directly replacing the entire cable will cause a great waste of resources. Replacing only the severely aged part of the cable body not only requires cutting and reconnecting the cable, which is complicated, time-consuming and labor-intensive, but may also affect the overall performance and stability of the photovoltaic power generation system. Therefore, we propose a UV-resistant cable for photovoltaic power generation. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to prevent the cable from aging unevenly due to long-term exposure of part of the cable body to ultraviolet rays.

[0006] In order to solve the above problems, the present invention provides a UV-resistant cable for photovoltaic power generation, comprising a cable body and a plurality of UV-resistant protective kits, wherein the cable body is composed of a wire core, an insulating layer coated on the outside of the wire core, and a sheath layer coated on the outside of the insulating layer, and the UV-resistant protective kit comprises a breathable support sleeve matching the cable body, the breathable support sleeve is sleeved on the cable body and slidably connected to the cable body, a matching UV-resistant sheath is sleeved on the outer wall of the breathable support sleeve, a connecting screw is fixedly installed on the breathable support sleeve, and a rod hole matching the connecting screw is provided on the UV-resistant sheath, and the connecting screw passes through the rod hole. A fixing screw barrel is sleeved on the outer wall of the connecting screw and is threadedly connected to it. A compression strip matching the purple-resistant sheath is arranged between the purple-resistant sheath and the fixing screw barrel. The two ends of the compression strip are respectively against the purple-resistant sheath and the fixing screw barrel. The end of the compression strip close to the purple-resistant sheath is arranged to be an arc surface matching the purple-resistant sheath. The connecting screw passes through the compression strip and is slidably connected to the compression strip. The purple-resistant sheath is a circular tubular structure formed by a rectangular UV-resistant sheet curled along the outer wall of the breathable support sleeve.

The new purple-resistant sheath can be fixed on the breathable support sheath, thereby completing the replacement of the purple-resistant sheath.

[0015] As a further improvement of the present application, the breathable support sleeve consists of a support tube body and a pair of breathable ring bodies, and the pair of breathable ring bodies are respectively fixedly installed at both ends of the support tube body. The support tube body is a porous mesh structure, and the inner diameter of the support tube body is larger than the diameter of the cable body, which is beneficial to the heat dissipation of the cable body.

[0016] As another improvement of the present application, a blowing and heat dissipation component is also provided on the cable body, and the blowing and heat dissipation component includes a support frame, a close-connecting plate, and a guide plate which are sleeved on the cable body. The close-connecting plate and the guide plate match the support frame, and the close-connecting plate and the guide plate are respectively fixedly mounted on both ends of the support frame. A close-connecting hole matching the cable body is opened in the middle of the close-connecting plate, and an air guide hole is opened in the middle of the guide plate.

DETAILED DESCRIPTION

[0034] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-6A UV-resistant cable for photovoltaic power generation is shown, comprising a cable body 001 and a plurality of UV-resistant protective kits 002, wherein the cable body 001 is composed of a wire core 101, an insulating layer 102 coated on the outside of the wire core 101, and a sheath layer 103 coated on the outside of the insulating layer 102, and the UV-resistant protective kit 002 comprises a breathable support sleeve 201 matching the cable body 001, the breathable support sleeve 201 is sleeved on the cable body 001 and is slidably connected to the cable body 001, a matching UV-resistant sheath 202 is sleeved on the outer wall of the breathable support sleeve 201, a connecting screw 203 is fixedly mounted on the breathable support sleeve 201, a through-rod hole 206 matching the connecting screw 203 is provided on the UV-resistant sheath 202, the connecting screw 203 penetrates the through-rod hole 206, and a threaded connection with the connecting screw 203 is sleeved on the outer wall of the connecting screw 203 The fixing screw barrel 205 is provided with a compression strip 204 matching the purple-resistant sheath 202 between the purple-resistant sheath 202 and the fixing screw barrel 205, and the two ends of the compression strip 204 are respectively against the purple-resistant sheath 202 and the fixing screw barrel 205. The end of the compression strip 204 close to the purple-resistant sheath 202 is set to an arc surface matching the purple-resistant sheath 202, and the connecting screw 203 passes through the compression strip 204 and is slidably connected thereto. The purple-resistant sheath 202 is a tubular structure formed by a rectangular UV-resistant sheet 207 curled along the outer wall of the breathable support sleeve 201, a pair of semicircular openings 208 are opened on the UV-resistant sheet 207, and the rod hole 206 is surrounded by a pair of semicircular openings 208. The UV-resistant sheet 207 is made of UV-resistant material (such as cross-linked polyethylene), and the purple-resistant protection kit 002 is provided with a variety of specifications according to different lengths.

[0037] Assume that after the cable is laid, there will be L meters of cable body 001 exposed to the sun, and this part of the cable body 001 is recorded as A. Before laying the cable, L is calculated according to the cable laying plan. According to L, the corresponding number and specification of ultraviolet-resistant protection kits 002 are taken and these ultraviolet-resistant protection kits 002 are put on the cable body 001. When laying the cable, these ultraviolet-resistant protection kits 002 are slid to A. The ultraviolet-resistant sheath 202 in the ultraviolet-resistant protection kit 002 can provide effective protection for this part of the cable body 001. To prevent the aging speed of this part of the cable body 001 from being accelerated due to long-term exposure to ultraviolet rays, and with the use of the cable, when the ultraviolet-resistant sheath 202 needs to be replaced, first, turn and unscrew the fixing screw 205 and remove the pressing strip 204, then the old ultraviolet-resistant sheath 202 can be removed, and then a new ultraviolet-resistant sheet 207 is taken, and the ultraviolet-resistant sheet 207 is curled along the outer wall of the breathable support sleeve 201 to form a new ultraviolet-resistant sheath 202, and finally, the pressing strip 204 is re-set on the connecting screw 203, and then the fixing screw 205 is removed. The fixing screw barrel 205 is screwed back onto the connecting screw rod 203 until the fixing screw barrel 205 is abutted against the pressing strip 204, so that the pressing strip 204 abuts against the new purple-resistant sheath 202, and the new purple-resistant sheath 202 can be fixed on the breathable support sleeve 201. In this way, the replacement of the purple-resistant sheath 202 can be completed, making the purple-resistant sheath 202 easy to replace. Therefore, through the setting of the purple-resistant protection kit 002, the purple-resistant protection kit 002 can provide effective protection for the part of the cable body 001 exposed to the sun, significantly improving The UV resistance of this part of the cable body 001 is improved, and the accelerated aging of this part of the cable body 001 due to long-term exposure to ultraviolet rays is avoided, thereby not only improving the service life of the cable, but also effectively avoiding the uneven aging of the cable, and the ultraviolet-resistant sheath 202 is very convenient to replace, making the ultraviolet-resistant protection kit 002 easy to maintain, which not only improves the practicality and reliability of the ultraviolet-resistant protection kit 002, but also improves the protective effect of the ultraviolet-resistant protection kit 002, thereby further improving the service life of the cable body 001.

[0038] See also Figure 6 The breathable support sleeve 201 is composed of a support tube body 209 and a pair of breathable ring bodies 210. The pair of breathable ring bodies 210 are fixedly installed at both ends of the support tube body 209. The support tube body 209 is a porous mesh structure. The inner diameter of the support tube body 209 is larger than the diameter of the cable body 001, which is beneficial to the heat dissipation of the cable body 001.

[0039] The second implementation method:

[0040] Figure 7-11A UV-resistant cable for photovoltaic power generation is shown. Different from the first embodiment, a blowing and heat dissipation component 003 is also provided on the cable body 001. The blowing and heat dissipation component 003 includes a support frame 301, a close connection plate 302, and a guide plate 303 which are sleeved on the cable body 001. The close connection plate 302 and the guide plate 303 match the support frame 301, and the close connection plate 302 and the guide plate 303 are respectively fixedly installed at both ends of the support frame 301. A close connection hole 304 matching the cable body 001 is opened in the middle of the close connection plate 302, and an air guide hole 305 is opened in the middle of the guide plate 303. The close connection plate 302 is slidably and sealedly connected to the cable body 001 through the close connection hole 304. The diameter of the air guide hole 305 is larger than the diameter of the cable body 001 and Smaller than the inner diameter of the support tube body 209, a pair of connecting plates 211 are fixedly installed on the compression strip 204, a connecting hole 212 is opened in the middle of the connecting plate 211, a connecting block 306 is penetrated on the guide plate 303, a threaded hole 307 matching the connecting hole 212 is opened in the middle of the connecting block 306, a support box 308 is arranged on one side of the support frame 301, an air duct 309 is connected between the support box 308 and the support frame 301, a heat dissipation fan 310 and a heat dissipation controller 004 are fixedly installed in the support box 308, a temperature sensor 311 for detecting the temperature of the cable body 001 is fixedly installed in the support frame 301, the temperature sensor 311 is connected to the heat dissipation controller 004 signal, and the heat dissipation controller 004 is connected to the heat dissipation fan 310 signal.

[0041] When laying the cable, all the purple-resistant protection kits 002 are placed on the side of the guide plate 303 away from the close-connected plate 302, and the adjacent purple-resistant protection kits 002 are fixedly connected by bolts, connecting plates 211, and connecting holes 212, and the blowing and cooling component 003 and the purple-resistant protection kit 002 closest to the blowing and cooling component 003 are fixedly connected by screws, connecting plates 211, connecting holes 212, connecting blocks 306, and threaded holes 307. During the use of the cable, the temperature sensor 311 can detect the temperature of the cable body 001, and the temperature data detected by the temperature sensor 311 will be fed back to the cooling controller 004. Those skilled in the art can reasonably set a temperature threshold value according to the actual situation and the normal operating temperature range of the cable body 001, and input this temperature threshold value to the cooling controller 004. When the temperature of the cable body 001 reaches the temperature threshold value, the cooling controller 004 will start the cooling fan 310 to dissipate the heat. After the hot air blower 310 is started, wind will be generated, and the wind will be blown toward the purple-resistant protection kit 002 through the air duct 309, the support frame 301, and the connecting block 306. Due to the porous mesh structure of the breathable ring body 210, the wind can pass through the breathable ring body 210 and blow toward the inner side of the support tube body 209 and the outer surface of the cable body 001, thereby having a heat dissipation effect on the cable body 001 and reducing the temperature of the cable body 001. After the temperature of the cable body 001 returns to normal, the heat dissipation controller 004 will automatically turn off the heat dissipation fan 310. Therefore, through the joint setting of the purple-resistant protection kit 002 and the blowing heat dissipation component 003, when the temperature of the cable body 001 inside the purple-resistant protection kit 002 is too high, the blowing heat dissipation component 003 can dissipate heat and cool this part of the cable body 001 to prevent the cable body 001 from being damaged due to excessive temperature, which can not only further improve the service life of the cable, but also improve the stability and reliability of the cable.

[0042] See also Fig.10 An air intake dustproof net 312 is embedded through the outer wall of the support box 308 at one end away from the support frame 301, and air can enter the support box 308 through the air intake dustproof net 312, and the air intake dustproof net 312 can intercept dust in the air.

Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
