Description

Technical Field

[0001] This utility model belongs to the field of foldable photovoltaic panel technology, specifically a cable protection structure for foldable photovoltaic panels. Background Technology

[0002] Solar photovoltaic (PV) systems, also known as photovoltaic systems, are facilities that convert solar energy into direct current (DC) electricity using the photovoltaic effect of photovoltaic semiconductor materials. In recent years, due to the increased construction and investment in my country's power, telecommunications, mobile, and network infrastructure, traditional PV power stations are generally built outdoors and installed on the ground using brackets. Building PV power stations on the ground requires ground preparation, bracket erection, etc., resulting in long construction cycles and heavy workloads. Moreover, the division of labor among ground preparation, bracket installation, and PV panel installation is quite specialized, leading to numerous problems in the professional coordination during on-site construction. This has led to a demand for foldable PV systems that are easy to install and support agricultural and water resource management programs, provide auxiliary power for construction sites, emergency areas, and off-grid charging stations, and can also serve as additional power sources to support existing generators or supply power to remote areas. Their ability to operate in both grid-connected and off-grid environments further expands their utility, meeting the needs of activities, venues, and communities that require reliable and sustainable power solutions.

[0003] Because photovoltaic panels need to be exposed to sunlight for a long time to achieve ideal photoelectric conversion efficiency, and the application scenarios of foldable photovoltaic panels are usually in desert or semi-desert areas such as the Middle East, where the sun is strong and there are often sandstorms, the wires connecting the photovoltaic panels are easily aged under the wind and sun if they are exposed to the outside for a long time. Therefore, protective structures for the cables need to be set up.

[0004] For example, the Chinese utility model patent for photovoltaic cable conduit with publication number CN211720191U includes a first half-tube and a second half-tube, wherein the first half-tube and the second half-tube are arranged opposite each other, one side of the first half-tube is movably connected to one side of the second half-tube, and the first half-tube and the second half-tube are rotatable about the movably connected side as an axis; the other side of the first half-tube and the other side of the second half-tube are shaped to fit together, so that they are locked together after the first half-tube and the second half-tube rotate to form a closed tube. When the photovoltaic cable malfunctions, this photovoltaic cable conduit can be opened at any time as needed for maintenance to locate the fault point of the photovoltaic cable, and can be quickly locked back after maintenance is completed; it effectively protects the photovoltaic cable while improving the convenience of maintenance, thereby extending the service life of the photovoltaic cable.

[0005] However, the aforementioned patents have the following problems: 1. Since foldable photovoltaic panels need to be folded and stored, and cables are usually placed on one side of the photovoltaic panel, the cables and their protective structure need to meet the folding requirements. However, the above-mentioned patent does not have the ability to be folded and stored, and therefore cannot be used on foldable photovoltaic panels.

[0006] 2. The above-mentioned patent has only through space at both ends after being closed. When the cable is completely wrapped by the above-mentioned patent and exposed to strong sunlight, heat will continuously accumulate inside and be difficult to dissipate in time, which will easily cause the cable to overheat and accelerate its aging.

[0007] 3. The protective structure of foldable photovoltaic panels needs to meet the folding requirements, so it is generally consistent with the tilt angle of the photovoltaic panel. If it is the structure of the above patent, rainwater can easily flow into the protective structure during rainfall, which can easily cause short circuit problems or cause corrosion of the cable surface. Utility Model Content

[0008] To overcome the shortcomings of existing technologies, this invention addresses the technical problem of providing cable protection while simultaneously meeting the need for folding and storage by incorporating a cable protection tube and a corrugated protection tube made of deformable material. The corrugated tube connector securely connects the corrugated and cable protection tubes, forming a unified whole that provides comprehensive cable protection, preventing damage from direct sunlight, wind, sand, and rain. Furthermore, the inclusion of baffles, which close together after the corrugated tube connector is inserted into the cable protection tube to form a complete plane, effectively prevents rainwater from entering the cable protection tube from both ends during rainfall. Additionally, the interlocking teeth... The closed, ring-shaped design securely holds the corrugated protective tube in place, preventing it from detaching and sealing the gaps between the tube and its connector to prevent rainwater from entering. This protective tube protects the cables connecting the photovoltaic panels. Ventilation holes connect the tube to the outside, facilitating heat dissipation and preventing heat buildup that could accelerate cable aging. Located at the bottom of the tube, the vents prevent direct sunlight from damaging the cables and causing them to age prematurely. They also prevent rainwater from flowing into the tube during rainfall.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a foldable photovoltaic panel cable protection structure, characterized in that it includes multiple photovoltaic supports, the tops of each photovoltaic support are hinged together by hinges, the bottoms of each photovoltaic support are hinged together by hinge wheels, a photovoltaic panel is fixedly connected to the surface of each photovoltaic support, a hollow cable protection tube is fixedly connected to one side of each photovoltaic support, each cable protection tube is parallel to the corresponding photovoltaic support, adjacent cable protection tubes are connected by corrugated protection tubes, and cables are connected between each photovoltaic panel, the cables passing through the cable protection tubes and the inside of the corrugated protection tubes.

[0010] Furthermore, each of the corrugated protective tubes is fitted with a corrugated tube connector at both ends. Each corrugated tube connector includes a sleeve and a retaining spring. The sleeve is internally connected and extends into the corrugated protective tube. Each end of the sleeve is provided with a set of elastic retaining springs. Each set of retaining springs can close together and wrap around the outside of the corrugated protective tube.

[0011] Furthermore, each set of the retaining springs has interlocking teeth on its inner side. Each interlocking tooth is arc-shaped, and each set of interlocking teeth can close together to form a ring and interlock to fix the outer wall of the corrugated protective tube.

[0012] Furthermore, each of the retaining springs has a baffle fixedly connected to its end. When each set of baffles is closed, it forms a complete plane that completely covers the end of the wire protection tube. The edges of two of the baffles in each set extend beyond the edge of the wire protection tube.

[0013] Furthermore, each of the spring clips has locking teeth on the surface of its contact with the wire protection tube.

[0014] Furthermore, each of the wire-threading protective tubes has multiple ventilation holes evenly distributed on its bottom side, and each of the wire-threading protective tubes is provided with a slope cover at the position corresponding to each ventilation hole, with the slope of each slope cover set along the inclination direction of the corresponding wire-threading protective tube.

[0015] Furthermore, each of the corrugated protective tubes has an easy-tear opening at both ends of its edge.

[0016] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: (1) By setting up a cable protection tube and a corrugated protection tube made of deformable material, the cable can be protected while meeting the need for folding and storage. By setting up a corrugated tube joint, the corrugated protection tube and the cable protection tube can be firmly connected, so that the cable protection tube and the corrugated protection tube form a whole to provide comprehensive protection for the cable and avoid direct sunlight and wind and rain damage to the cable.

[0017] (2) By setting baffles, after the corrugated pipe joint is inserted into the wire protection pipe, they close to each other to form a complete plane, which effectively prevents rainwater from entering the wire protection pipe from both ends during rainfall. In addition, the interlocking teeth close in a ring shape to firmly interlock and fix the corrugated protection pipe, preventing the corrugated protection pipe from falling off, and also sealing the gap between the corrugated protection pipe and the corrugated pipe joint to prevent rainwater from leaking into the corrugated protection pipe.

[0018] (3) By setting up a wire protection tube, the cables connecting the photovoltaic panels can be protected. By setting up a vent hole, the wire protection tube can be connected to the inside and outside, thereby achieving a good heat dissipation effect and avoiding the accumulation of heat in the wire protection tube, which is difficult to dissipate and causes the cables to age faster. The vent hole is set on the bottom side of the wire protection tube, which effectively avoids the direct sunlight from shining on the cable and causing the cable to age due to strong ultraviolet radiation. At the same time, it also prevents rainwater from flowing into the wire protection tube through the vent hole during rainfall. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1-6As shown, a foldable photovoltaic panel cable protection structure includes multiple photovoltaic brackets 10, each photovoltaic bracket 10 with a photovoltaic panel 11 fixedly connected to its surface. The photovoltaic brackets 10 are arranged alternately to form a wave-like undulating structure. The tops of the photovoltaic brackets 10 are hinged together by hinges 12, and the bottoms of the photovoltaic brackets 10 are hinged together by hinge wheels 13. Cables are connected between the photovoltaic panels 11.

[0028] like Figure 1-6 As shown, a wire protection tube 14 is fixedly connected to one side of each photovoltaic bracket 10. Each wire protection tube 14 is parallel to the corresponding photovoltaic bracket 10. After the photovoltaic panel is unfolded, there is an angle between each wire protection tube 14 and the ground. The cable can be directly passed from the photovoltaic bracket 10 into the wire protection tube 14, or the cable can be passed from the end opening of the wire protection tube 14 into the wire protection tube 14. Each wire protection tube 14 has multiple ventilation holes 23 evenly distributed on its bottom side in the direction of inclination. Each wire protection tube 14 is provided with a slope cover 24 at the position corresponding to each ventilation hole 23. Each slope cover 24 is provided along the inclination direction of the wire protection tube 14.

[0029] By setting up the cable protection tube 14, the cables connecting the photovoltaic panels can be protected. By setting up the vent hole 23, the cable protection tube 14 can be connected to the inside and outside, thereby achieving a good heat dissipation effect and preventing heat from accumulating inside the cable protection tube 14 and causing the cables to age faster. The vent hole 23 is set on the bottom side of the cable protection tube 14, which effectively prevents the cables from being directly exposed to sunlight and thus aging due to strong ultraviolet rays. At the same time, it prevents rainwater from flowing into the cable protection tube 14 through the vent hole 23 during rainfall.

[0030] Meanwhile, by setting up a slope cover 24 along the inclined direction of the cable protection pipe 14, the edge of the vent 23 is blocked, preventing rainwater from flowing along the bottom side of the inclined cable protection pipe 14 and into the vent 23 during rainfall. This provides a better waterproof effect without affecting the normal heat dissipation of the vent 23. In addition, the slope cover 24 can also effectively block wind and sand, preventing a large amount of wind and sand from directly damaging the cables inside the cable protection pipe 14. Furthermore, the vent 23 allows workers to easily insert tools into the cable protection pipe 14 to assist in cable threading or adjust the cable position during cable threading.

[0031] like Figure 1-6As shown, a corrugated protective tube 15 is connected between the ends of adjacent cable protection tubes 14. The corrugated protective tube 15 is made of a deformable material. Each corrugated protective tube 15 has a corrugated tube connector 16 at both ends. Each corrugated tube connector 16 includes a sleeve 17. The sleeve 17 passes through and enters the end of the corrugated protective tube 15. The cable can pass through the corrugated tube connector 16 and the inside of the corrugated protective tube 15. The end of the sleeve 17 is provided with four elastic retaining springs 18. The retaining springs 18 can be engaged in the end of the cable protection tube 14. The retaining springs 18 can wrap around the outside of the corrugated protective tube 15. The surface of the retaining springs 18 that contacts the cable protection tube 14 is provided with retaining teeth 22.

[0032] By setting a corrugated protective tube 15 made of deformable material, the cable can be protected while meeting the need for folding and storage. By setting a corrugated tube connector 16, the corrugated protective tube 15 can be firmly connected to the cable protection tube 14, so that the cable protection tube 14 and the corrugated protective tube 15 form a whole to provide comprehensive protection for the cable and avoid direct sunlight and wind and rain damage to the cable.

[0033] like Figure 1-6 As shown, each set of retaining springs 18 has a baffle 19 at its end. Each set of baffles 19 can close together to form a complete plane and completely cover the end of the wire protection tube 14. The edges of the two baffles 19 in opposite directions in each set extend beyond the edge of the wire protection tube 14. Each retaining spring 18 has an arc-shaped biting tooth 20 on its inner side. Each set of biting teeth 20 can close together to form an annular biting corrugated protective tube 15 outer wall.

[0034] like Figure 1-6 As shown, by setting baffles 19, after the corrugated pipe joint 16 is inserted into the wire protection pipe 14, they close together to form a complete plane, which effectively prevents rainwater from entering the wire protection pipe 14 from both ends during rainfall. In addition, the interlocking teeth 20 close in a ring shape to firmly interlock and fix the corrugated protection pipe 15, preventing the corrugated protection pipe 15 from falling off, and also sealing the gap between the corrugated protection pipe 15 and the corrugated pipe joint 16 to prevent rainwater from leaking into the corrugated protection pipe 15.

[0035] The design of the baffle 19 extending beyond the edge of the cable protection tube 14 makes it easy to pull out the corrugated tube connector 16 inserted into the cable protection tube 14, thereby facilitating the disassembly and assembly of the corrugated protection tube 15 and making it convenient for cable inspection and maintenance.

[0036] like Figure 1-6As shown, the corrugated protective tube 15 has an easy-tear opening 21 at its end edge. By setting the easy-tear opening 21, the corrugated protective tube 15 can be quickly torn open after aging and damage, so as to quickly remove the corrugated protective tube 15, which is convenient for line maintenance. At the same time, it prevents the damaged and aged corrugated protective tube 15 from being reused due to worker misoperation, thereby ensuring the protection effect on the cable.
