Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable technology, specifically a new energy photovoltaic cable. Background Technology

[0002] New energy photovoltaic cables are cables specifically designed for solar photovoltaic power generation systems. They carry the task of transmitting electricity from solar panels to inverters and other system equipment, and meet the requirements for long-term, stable and reliable operation of photovoltaic power generation systems.

[0003] In existing technologies, photovoltaic cables are partially exposed during use and are not adequately protected. When external forces collide with them, the cables cannot effectively absorb the impact, potentially leading to damage. Furthermore, the design of existing photovoltaic cables does not consider the ease of fault location. When a cable breaks, it is difficult for workers to visually locate the damaged area, increasing the difficulty of maintenance and troubleshooting.

[0004] Therefore, those skilled in the art provide a new energy photovoltaic cable to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a new energy photovoltaic cable to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A new energy photovoltaic cable includes an outer protective layer, with a rubber block fixedly connected to the outer side of the outer protective layer along the axial direction. A pH-sensitive fiber layer is compositely connected to the inner circumferential surface of the outer protective layer, and an inner protective layer is compositely connected to the inner circumferential surface of the pH-sensitive fiber layer. Four reinforcing ribs are fixedly connected at equal intervals to the inner circumferential surface of the inner protective layer. The other side of each of the four sets of reinforcing ribs is fixedly connected to a positioning support block. Four sets of mounting grooves are equally spaced on the inner side of the positioning support block, and a cable core is provided on the inner side of each of the four sets of mounting grooves. A filling isolation layer is compositely connected between the positioning support block and the inner protective layer.

[0008] As a further embodiment of this utility model: anti-slip grooves are equidistantly provided on the surface of the four sets of rubber blocks, and the rubber blocks are made of polyurethane material.

[0009] As a further improvement of this utility model: buffer columns are fixedly connected at equal intervals through the inner side of the outer protective layer, and the buffer columns are made of polyethylene rubber material.

[0010] As a further improvement of this invention, the pH-sensitive fiber layer is made of a mixture of bromocresol green, phenolphthalein and fiber layer material.

[0011] As a further improvement of this utility model, the outer protective layer and the inner protective layer are made of polyvinyl chloride material, aluminum alloy mesh reinforcement material, and woven protective material.

[0012] As a further improvement of this invention, the filling and insulating layer is made of a mixture of glass fiber and resin.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses rubber blocks, built-in buffer columns, reinforcing ribs and positioning support blocks to enable new energy photovoltaic cables to directly absorb external impact forces (such as construction misoperation, falling rocks, hail) during use, protect the internal structure of the cable, extend the service life of the cable, and the anti-slip groove greatly increases the friction coefficient to prevent the cable from shifting or slipping when installed on the bracket or roof, especially to ensure long-term fixation in slope or vibrating environments.

[0015] 2. This utility model uses a pH-sensitive layer made of a mixture of bromocresol green and phenolphthalein. When the outer protective layer is damaged and the inside is exposed to the external environment, the layer will turn yellow when in contact with acidic substances and red when in contact with alkaline substances. This obvious color change allows staff to find and accurately locate the cable damage point from a distance without the need for complicated instruments, greatly simplifying the troubleshooting and repair process and shortening downtime.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and 2 As shown, this utility model embodiment provides a new energy photovoltaic cable, including an outer protective layer 1. A rubber block 2 is fixedly connected to the outer side of the outer protective layer 1 along the axial direction. A pH-sensitive fiber layer 3 is compositely connected to the inner circumferential surface of the outer protective layer 1. An inner protective layer 4 is compositely connected to the inner circumferential surface of the pH-sensitive fiber layer 3. Four reinforcing ribs 6 are fixedly connected at equal intervals to the inner circumferential surface of the inner protective layer 4. The other side of each of the four sets of reinforcing ribs 6 is fixedly connected to a positioning support block 7. Four sets of mounting grooves 71 are equally spaced on the inner side of the positioning support block 7. A cable core 8 is provided on the inner side of each of the four sets of mounting grooves 71. A filling isolation layer 5 is compositely connected between the positioning support block 7 and the inner protective layer 4.

[0023] In this embodiment, the rubber block 2 is fixedly connected along the outer surface of the outer protective layer 1, serving to enhance the buffer protection of the cable. The rubber material is elastic and can effectively absorb external impacts and pressures, reducing the impact of the external environment on the cable. The pH-sensitive fiber layer 3 is coated with a mixture of bromocresol green and phenolphthalein. When the outer protective layer 1 is damaged, external substances come into contact with the pH-sensitive fiber layer 3. Acidic substances turn yellow upon contact with the pH-sensitive fiber layer 3, while alkaline substances turn red, facilitating the inspection of cable damage and timely repair by personnel. The inner protective layer 4 is compositely connected to the inner circumferential surface of the pH-sensitive fiber layer 3. When the outer protective layer 1 is damaged, the inner protective layer 4 protects the internal cable core 8. The reinforcing rib 6 is fixedly connected to the inner circumferential surface of the inner protective layer 4. The reinforcing rib 6 enhances the tensile strength and compressive strength of the cable, improving its durability in harsh environments. The positioning support block 7 is connected to the reinforcing rib 6 to ensure the stability of the internal structure of the cable, maintain the positional relationship of each component, and prevent displacement or deformation during use. The filling isolation layer 5 is compositely connected between the positioning support block 7 and the inner protective layer 4. The function of the filling isolation layer 5 is to prevent current leakage inside the cable, enhance electrical isolation performance, and improve the mechanical stability and resistance to external damage of the cable.

[0024] like Figure 1 As shown, optionally, anti-slip grooves 21 are provided at equal intervals on the surface of the four sets of rubber blocks 2, and the rubber blocks 2 are made of polyurethane material.

[0025] In this embodiment, the anti-slip groove 21 mainly increases the friction on the surface of the rubber block 2, which helps prevent the cable from sliding or slipping during installation. Especially when it is necessary to fix the cable to the equipment or bracket, the anti-slip groove 21 can provide stronger adhesion and prevent the cable from moving due to external vibration or environmental factors.

[0026] like Figure 4 As shown, optionally, buffer columns 11 are fixedly connected through the inner side of the outer protective layer 1 at equal intervals, and the buffer columns 11 are made of polyethylene rubber material.

[0027] In this embodiment, the polyethylene rubber material has good elasticity and flexibility, which can effectively absorb and buffer external impact or vibration. When external objects or the environment apply pressure to the cable, the buffer post 11 will play a buffering role, preventing excessive impact force from being directly transmitted to the inside of the cable, thereby reducing cable damage and extending its service life.

[0028] like Figure 2 As shown, optionally, the pH-sensitive fiber layer 3 is made of a mixture of bromocresol green, phenolphthalein and fiber layer material.

[0029] In this embodiment, the pH-sensitive fiber layer 3 serves to provide a visual indicator by utilizing the properties of the mixed reagent of bromocresol green and phenolphthalein, helping staff to detect cable damage in a timely manner.

[0030] like Figure 2 As shown, optionally, the outer protective layer 1 and the inner protective layer 4 are made of polyvinyl chloride material, aluminum alloy mesh reinforcement material, and woven protective material.

[0031] In this embodiment, polyvinyl chloride (PVC) has good acid and alkali resistance, and can resist the corrosion of various chemicals. Regardless of whether the cable is in an acidic or alkaline environment, PVC material can effectively prevent corrosion, ensuring the long-term stable operation of the cable. The aluminum alloy mesh layer enhances the overall mechanical strength of the cable, resisting external impacts, pressure, or tension, preventing damage when subjected to external forces. It provides additional physical protection against compression, stretching, or other external forces. The braided protective layer typically uses high-strength fibers (such as nylon or polyester fibers), increasing the cable's flexibility and abrasion resistance, making it less prone to breakage during long-term use. It effectively absorbs and disperses external forces, preventing scratches or damage to the cable surface due to friction.

[0032] like Figure 2 As shown, optionally, the filling isolation layer 5 is a mixture of glass fiber and resin.

[0033] In this embodiment, glass fiber can effectively improve the mechanical strength of the filling insulation layer. Its high tensile strength and impact resistance enable the filling layer 5 to withstand external pressure or tension, enhancing the overall structural stability of the cable. Resin can provide a solid base for glass fiber, increasing its durability and rigidity. The hardness of the resin makes the entire insulation layer more robust, effectively preventing damage to the internal components of the cable from external forces.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
