Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a UV-resistant photovoltaic cable. Background Technology

[0002] Photovoltaic cables are cables specifically designed for transmitting electrical energy in the DC side circuit of solar photovoltaic power station systems. They are typically composed of tin-plated copper core conductors and cross-linked polyethylene insulation material. They are characterized by small size, light weight, good mechanical properties, and strong chemical stability. They also have properties such as resistance to high and low temperatures, protection against ultraviolet radiation, water resistance, salt spray resistance, resistance to weak acids and alkalis, aging resistance, and flame retardancy. They are widely used and play an important role in solar power generation systems.

[0003] In existing technologies, many outdoor cables are affected by the cable route, making it difficult to keep the cable installation points on the same line. This causes some cables to be twisted during installation, and the twisted parts are prone to cracking of the cable sheath, which can easily affect the protective effect of the cable surface. Moreover, long-term outdoor use requires the cable surface to have strong UV resistance. Utility Model Content

[0004] This utility model mainly provides a UV-resistant photovoltaic cable that is easy to install and has good protective performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a UV-resistant photovoltaic cable, comprising a cable core and a cable protective sleeve, wherein the cable protective sleeve is fixedly wrapped around the outer surface of the cable core, and a fixable mounting sleeve is movably fitted on the outer surface of the cable protective sleeve, and a fixable fixing plate is rotatably connected to the side of the mounting sleeve.

[0006] The cable protection sleeve includes an insulating fixing sleeve, an insulating and waterproof interlayer, a heat insulation spacer layer, an ultraviolet-resistant and corrosion-resistant sleeve, and an ultraviolet-resistant coating. The outer surface of the cable core is wrapped and fixed with an insulating fixing sleeve. The outer surface of the insulating fixing sleeve is wrapped and fixed with an insulating and waterproof interlayer. The outer surface of the insulating and waterproof interlayer is fixed with a heat insulation spacer layer. The outer surface of the heat insulation spacer layer is fixed with an ultraviolet-resistant and corrosion-resistant sleeve. The outer surface of the ultraviolet-resistant and corrosion-resistant sleeve is coated with an ultraviolet-resistant coating.

[0007] Preferably, a fixing block is slidably sleeved inside the mounting sleeve on the side away from the fixing plate. A fixing screw is rotatably connected to the side of the fixing block away from the cable protection sleeve via a bearing. The fixing screw is threaded inside the side wall of the mounting sleeve. During installation, the position of the mounting sleeve is first adjusted according to the installation requirements. After the adjustment is completed, the fixing screw can be directly turned to drive the fixing block to clamp the cable core and the cable protection sleeve, thereby fixing the mounting sleeve to the cable core and the cable protection sleeve.

[0008] Preferably, an anti-slip pad is glued to the side of the fixing clamp near the cable protective sleeve to increase the friction between the fixing clamp and the outer surface of the cable protective sleeve. The side of the anti-slip pad and the fixing clamp away from the fixing screw are both set to be arc-shaped to cooperate with the cable protective sleeve, so as to facilitate the fixing screw and the anti-slip pad to fit with the outer surface of the cable protective sleeve.

[0009] Preferably, the fixing screw is configured as a horizontally placed T-shape, which facilitates the tightening of the fixing screw. The mounting and fixing sleeve has a threaded hole in the side wall away from the fixing plate that mates with the fixing screw, which facilitates the tightening of the fixing screw and drives the fixing clamp to move.

[0010] Preferably, the fixing plate has a plurality of fixing holes equidistantly arranged inside. A connecting screw is fixed to the side of the fixing plate near the mounting sleeve, and a rotating block is fixed to the side of the connecting screw away from the fixing plate. A connecting sleeve block is rotatably fitted on the rotating block. The connecting sleeve block is fixed to the outer surface of the mounting sleeve. A fixing nut is threaded onto the connecting screw between the connecting sleeve block and the fixing plate. Through the rotatable design of the fixing plate, the angle between the fixing plate and the cable protection sleeve can be adjusted according to the angle of the installation point during installation, thereby improving the applicability of photovoltaic cable installation.

[0011] Preferably, the connecting sleeve has a horizontally placed T-shaped rotating groove inside, which cooperates with the rotating block and the connecting screw to prevent the rotating block from separating from the connecting sleeve. The thickness of the connecting screw is greater than the thickness of the fixing nut, ensuring that the fixing nut can rotate to separate from the connecting sleeve, thereby allowing the fixing plate to rotate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the rotatable mounting sleeve allows for adjustment of the installation position and the angle of the fixing plate according to the installation location requirements. This solves the problem of existing UV-resistant photovoltaic cables that are easy to install and have good protective performance, improves the convenience of outdoor cable installation, avoids cable twisting leading to breakage, and ensures the applicability of the cable during installation.

[0014] 2. In this utility model, the UV-resistant coating and UV-resistant anti-corrosion sheath greatly improve the UV resistance of the cable surface, preventing the cable from aging under prolonged sunlight exposure, thereby improving the overall protective performance of the cable surface. Combined with the internal heat insulation layer, it prevents the core from heating up due to sunlight. Attached Figure Description

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a UV-resistant photovoltaic cable, including a cable core 1 and a cable protective sleeve 2. The cable protective sleeve 2 is wrapped and fixed on the outer surface of the cable core 1. A fixable mounting sleeve 3 is movably fitted on the outer surface of the cable protective sleeve 2. A fixable fixing plate 4 is rotatably connected to the side of the mounting sleeve 3.

[0023] The cable protection sleeve 2 includes an insulating fixing sleeve 21, an insulating and waterproof interlayer 22, a heat insulation spacer 23, an ultraviolet-resistant and corrosion-resistant sleeve 24, and an ultraviolet-resistant coating 25. The outer surface of the cable core 1 is wrapped and fixed with the insulating fixing sleeve 21. The outer surface of the insulating fixing sleeve 21 is wrapped and fixed with the insulating and waterproof interlayer 22. The outer surface of the insulating and waterproof interlayer 22 is fixed with the heat insulation spacer 23. The outer surface of the heat insulation spacer 23 is fixed with the ultraviolet-resistant and corrosion-resistant sleeve 24. The outer surface of the ultraviolet-resistant and corrosion-resistant sleeve 24 is coated with an ultraviolet-resistant coating 25.

[0024] like Figure 3As shown, a fixing clip 5 is slidably sleeved inside the mounting sleeve 3 on the side away from the fixing plate 4. A fixing screw 6 is rotatably connected to the side of the fixing clip 5 away from the cable protection sleeve 2 via a bearing. The fixing screw 6 is threaded into the inside of the side wall of the mounting sleeve 3. During installation, the position of the mounting sleeve 3 is first adjusted according to the installation requirements. After the adjustment is completed, the fixing screw 6 can be directly turned to drive the fixing clip 5 to clamp the cable core 1 and the cable protection sleeve 2, thereby fixing the mounting sleeve 3 to the cable core 1 and the cable protection sleeve 2.

[0025] like Figure 3 As shown, the fixing clamp 5 is glued to the side of the cable protection sleeve 2 with an anti-slip pad 7 to increase the friction between the fixing clamp 5 and the outer surface of the cable protection sleeve 2. The side of the fixing clamp 5 away from the fixing screw 6 is set to be arc-shaped to cooperate with the cable protection sleeve 2, so that the fixing screw 6 and the anti-slip pad 7 can fit into the outer surface of the cable protection sleeve 2.

[0026] like Figure 2 and Figure 3 As shown, the fixing screw 6 is set as a horizontally placed T-shape, which makes it easy to turn the fixing screw 6. The mounting fixing sleeve 3 has a threaded hole in the side wall away from the fixing plate 4 that mates with the fixing screw 6, which makes it easy to turn the fixing screw 6 and drive the fixing clamp 5 to move.

[0027] like Figure 2 As shown, the fixing plate 4 has several fixing holes equidistantly arranged inside. A connecting screw 8 is fixed on the side of the fixing plate 4 near the mounting sleeve 3, and a rotating block 9 is fixed on the side of the connecting screw 8 away from the fixing plate 4. A connecting sleeve block 10 is rotatably sleeved on the rotating block 9. The connecting sleeve block 10 is fixed to the outer surface of the mounting sleeve 3. A fixing nut 11 is threaded on the connecting screw 8 between the connecting sleeve block 10 and the fixing plate 4. Through the rotatable design of the fixing plate 4, the angle between the fixing plate 4 and the cable protection sleeve 2 can be adjusted according to the angle of the installation point during installation, which improves the applicability of photovoltaic cable installation.

[0028] like Figure 3 As shown, the connecting sleeve 10 has a horizontally placed T-shaped rotating groove inside, which cooperates with the rotating block 9 and the connecting screw 8 to prevent the rotating block 9 from separating from the connecting sleeve 10. The thickness of the connecting screw 8 is greater than the thickness of the fixing nut 11, ensuring that the fixing nut 11 can rotate to separate from the connecting sleeve 10, thereby allowing the fixing plate 4 to rotate.

[0029] The usage and working principle of this device are as follows: When it is necessary to install cable core 1, first put the mounting sleeve 3 on the cable protective sleeve 2 from one end of the cable, then pull the mounting sleeve 3 to adjust its position. After adjustment, tighten the fixing screw 6. The fixing screw 6 moves and drives the fixing clamp 5 to move towards the cable protective sleeve 2, cooperating with the mounting sleeve 3 to clamp the cable protective sleeve 2. After the cable protective sleeve 2 is fixed with the mounting sleeve 3, rotate the fixing plate 4 so that the fixing plate 4 fits with the connector with the fixing point. When the fixing plate 4 rotates, the connecting screw 8 drives the rotating block 9 to rotate inside the connecting sleeve block 10. After rotation, tighten the fixing nut 11 so that the fixing nut 11 clamps the connecting sleeve block 10, fixing the fixing plate 4 to the cable core 1. Then, fix the fixing plate 4 to the connector with bolts.
