[0002] Driven by the national energy transition strategy, my country's distributed photovoltaic industry is experiencing unprecedented rapid development. Its cumulative installed capacity has achieved a significant leap in a short period of time, accounting for nearly half of the country's total photovoltaic power generation capacity, and has become the core driving force for promoting energy structure transformation.

[0003] However, with the rapid expansion of rooftop distributed photovoltaic (PV) installations, bottlenecks in project construction have become increasingly prominent. Among these, the efficiency and reliability of cable tray installation have become key factors restricting the overall project progress and quality. Currently, for fixing cable trays on corrugated steel roofs, traditional methods often use ordinary metal cable ties or dovetail screws for direct connection. This approach is not only inefficient but also highly prone to causing physical damage to the cables and the cable trays themselves. Therefore, it is difficult to guarantee the long-term stable operation of PV power plants, necessitating technological innovation and optimization. Utility Model Content

[0031] This utility model proposes a rooftop photovoltaic cable laying device 100.

[0032] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the roof photovoltaic cable laying device 100 is applied to a corrugated steel roof 200, the corrugated steel roof 200 having corrugated peaks 210. The roof photovoltaic cable laying device 100 includes a mounting clamp 1, a crossbeam 2, and a cable tray 3. The mounting clamp 1 includes a first clamping member 11 and a second clamping member 12 that are detachably connected to each other. A first clamping groove 11a is formed on the first clamping member 11, and a second clamping groove 12a is formed on the second clamping member 12. The inner wall of the first clamping groove 11a and the inner wall of the second clamping groove 12a enclose a clamping space 1a, which is used to clamp the corrugated peaks 210. The crossbeam 2 is detachably connected to the end of the first clamping member 11 away from the clamping space 1a, or the crossbeam 2 is detachably connected to the end of the second clamping member 12 away from the clamping space 1a. The cable tray 3 is detachably connected to the crossbeam 2.

[0033] In this embodiment, the mounting fixture 1 includes a first clamping member 11 and a second clamping member 12 that are detachably connected to each other. Optionally, the detachable connection between the first clamping member 11 and the second clamping member 12 is a snap-fit ​​connection. One end of the first clamping member 11 has a snap hole, and one end of the second clamping member 12 has a snap fastener that matches the snap hole. Quick connection and disassembly are achieved through the cooperation of the snap hole and the snap fastener. Alternatively, the first clamping member 11 and the second clamping member 12 can also be connected by fasteners such as pins or bolts. Through holes can be provided on the first clamping member 11 and the second clamping member 12 respectively, and pins or bolts can be passed through the first clamping member 11 or the second clamping member 12 in sequence. When a pin is used, a wedge-shaped pin hole is provided at the end of the pin. When another wedge-shaped workpiece is inserted into the pin hole, the first clamping member 11 and the second clamping member 12 are gradually clamped together as the wedge-shaped workpiece gradually enters the pin hole. When bolts are used, they are used in conjunction with nuts. As the bolts and nuts are gradually tightened, the first clamping member 11 and the second clamping member 12 gradually clamp together. The first clamping member 11 has a first clamping groove 11a, and the second clamping member 12 has a second clamping groove 12a. The inner walls of the first clamping groove 11a and the second clamping groove 12a enclose a clamping space 1a. The shape of the clamping space 1a is adapted to the corrugated peaks 210 of the corrugated roof 200, which can tightly clamp the corrugated peaks 210, thereby firmly fixing the installation clamp 1 to the corrugated roof 200. Soft pads can be provided on the inner walls of the first clamping groove 11a and the second clamping groove 12a. The soft pads can be made of rubber. Rubber has good elasticity and can provide a certain cushioning when clamping the corrugated peaks 210, avoiding damage to the corrugated peaks 210, and also increasing the stability of the clamping. The main structure of the first clamping member 11 and the second clamping member 12 can be made of high-strength aluminum alloy material. Aluminum alloy material has the advantages of light weight, high strength and corrosion resistance, which can ensure the stability and reliability of the installation clamp 1 during long-term use, while reducing the weight of the whole device and making it easy to install and transport.

[0034] The connection between the crossbeam 2 and the mounting clamp 1 is detachable. Optionally, one end of the crossbeam 2 has a connecting hole, and the end of the first clamping member 11 or the second clamping member 12 away from the clamping space 1a has a connecting post that matches the connecting hole. The connection between the crossbeam 2 and the mounting clamp 1 is achieved by inserting the connecting post into the connecting hole and fixing it with bolts. This connection method ensures the stability of the connection and facilitates disassembly and replacement. Alternatively, the crossbeam 2 and the mounting clamp 1 can also be connected by bolts or other fasteners. The main structure of the crossbeam 2 can be made of high-strength steel, which has high strength and rigidity and can withstand large loads, providing stable support for the cable tray 3. The cross-sectional shape of the crossbeam 2 is rectangular, and its dimensions are designed according to the weight and size of the cable tray 3 to ensure that it can meet the load-bearing requirements in actual use. The length of the crossbeam 2 can be customized according to the actual size of the roof to adapt to roofs of different sizes.

[0035] The connection between the cable tray 3 and the crossbeam 2 is also detachable. Optionally, the bottom of the cable tray 3 has mounting holes, and the upper surface of the crossbeam 2 has mounting posts that match the mounting holes. The cable tray 3 and the crossbeam 2 are connected by inserting the mounting posts into the mounting holes. This connection method facilitates the installation and removal of the cable tray 3, and also facilitates the maintenance and repair of the cables inside the cable tray 3. Alternatively, bolts can be inserted through the bottom of the cable tray 3, passing through the crossbeam 2, and tightened with nuts to secure the crossbeam 2 to the bottom wall of the cable tray 3. The cable tray 3 can be made of flame-retardant PVC material. PVC material has good insulation and flame-retardant properties, which can effectively protect the cables and prevent them from being damaged during laying, while also meeting fire safety requirements. The cable tray 3 can also be made of corrosion-resistant metal materials such as stainless steel. The inside of the cable tray 3 can also be equipped with multiple partitions extending along the length of the cable tray 3, dividing the cable tray 3 into multiple independent channels. One or more cables can be laid in each channel, which can avoid mutual interference between cables and improve the laying quality and reliability of cables.

[0036] The rooftop photovoltaic cable laying device 100 of this embodiment uses an installation clamp 1 to quickly clamp the device onto the corrugated peaks 210 of the corrugated steel roof 200 via clamping grooves on the first clamping member 11 and the second clamping member 12 of the installation clamp 1, achieving rapid fixation of the device on the roof. The detachable connection of the installation clamp 1, as well as the detachable connection of the crossbeam 2 and the cable tray 3, makes the installation and disassembly process of the entire device more convenient and greatly improves the installation efficiency. The crossbeam 2 expands the support area and distributes the weight of the cable tray 3, making the fixation of the entire device on the roof more stable and improving the reliability of the device. Through the cooperation of the above technical means, the rooftop photovoltaic cable laying device 100 of this utility model not only has high installation efficiency but also provides stable support and has high reliability.

[0037] Please see Figure 2 In one embodiment of the present invention, the end of the first clamping member 11 away from the clamping space 1a is bent and forms a bearing portion 111; the crossbeam 2 is detachably connected to the bearing portion 111, and the end of the second clamping member 12 away from the clamping space 1a abuts against the side of the bearing portion 111 facing the clamping space 1a.

[0038] In this embodiment, the end of the first clamping member 11 furthest from the clamping space 1a is bent to form a support portion 111. This support portion 111 is primarily designed to increase the support area of ​​the entire device, thereby enhancing its stability on the roof. Considering the large load that the bent portion of the support portion 111 will bear, higher requirements are placed on its structural strength and stability. Therefore, the bent portion of the support portion 111 can be thickened, and a smooth transition is implemented at the bend to avoid structural damage caused by stress concentration. The end of the second clamping member 12 furthest from the clamping space 1a is in close contact with the side of the support portion 111 facing the clamping space 1a. This design aims to strengthen the support; the contact action of the second clamping member 12 with the support portion 111 effectively disperses the load borne by the support portion 111, thereby enhancing the load-bearing capacity and stability of the entire device. The end shape of the support portion 111 matches the shape of the bottom wall of the cable tray 3, ensuring a tight fit and good support effect; for example, one portion may protrude while the other is recessed.

[0039] Please see Figure 2 In one embodiment of the present invention, a bearing plane 1111 is formed on one side of the bearing part 111 facing away from the clamping space 1a, and an abutting plane is formed on the bottom wall of the cable tray 3. The bearing plane 1111 abuts and fits against the abutting plane.

[0040] In this embodiment, to ensure good contact and support with the bottom wall of the cable tray 3, the top wall of the supporting part 111 has a supporting plane 1111, and the bottom wall of the cable tray 3 correspondingly has an abutment plane. When the cable tray 3 is installed on the supporting part 111, the supporting plane 1111 and the abutment plane can fit tightly together. This plane-to-plane contact method, compared with other contact methods, such as point contact or curved surface contact, is advantageous in directly controlling the level of the supporting plane 1111 to ensure that the position of the cable tray 3 remains horizontal.

[0041] Further, please refer to Figure 3 In one embodiment of the present invention, a hinge groove 11b is provided on the side of the first clamping member 11 facing the second clamping member 12, and the hinge groove 11b is located at the end of the first clamping member 11 away from the clamping space 1a; a hinge shaft 121 is provided on the side of the second clamping member 12 facing the first clamping member 11, and the hinge shaft 121 is located at the end of the second clamping member 12 away from the clamping space 1a; both the hinge groove 11b and the hinge shaft 121 are arranged parallel to the corrugated crest 210, and the hinge shaft 121 is hinged to the inner wall of the hinge groove 11b.

[0042] In this embodiment, the hinge shaft 121 and the second clamping member 12 are integrally formed, which can be achieved by machining or integral casting on the second clamping member 12. To facilitate smoother rotation of the first clamping member 11 relative to the second clamping member 12, the end of the second clamping member 12 can be bent towards the first clamping member 11, and the hinge shaft 121 is provided at the end of the second clamping member 12. By hingedly connecting the first clamping member 11 and the second clamping member 12, this embodiment avoids the problem of low assembly efficiency caused by scattered parts. In actual installation, clamping can be achieved simply by rotating the first clamping member 11 and the second clamping member 12, without any extra alignment steps, making it simpler and faster. This design significantly improves installation efficiency, especially in situations requiring rapid installation and disassembly, effectively saving time and labor. Furthermore, the hinged design enhances the flexibility and adaptability of the device, allowing it to better adapt to corrugated peaks 210 of different shapes and sizes, further improving the versatility and reliability of the device.

[0043] Further, please refer to Figure 4 In one embodiment of the present invention, the roof photovoltaic cable laying device 100 further includes a leveling component 4, which is disposed on the top wall of the crossbeam 2. The top wall of the leveling component 4 has an adjusting plane 41, which is horizontally arranged. The bottom wall of the cable tray 3 forms an abutting plane, and the adjusting plane 41 abuts and fits against the abutting plane.

[0044] In this embodiment, considering the inclined installation of the corrugated steel roof, to ensure the horizontal placement of the cable tray 3, the leveling component 4 is installed on the top wall of the crossbeam 2, and its top wall has a horizontally positioned adjusting plane 41. The bottom wall of the cable tray 3 forms an abutment plane. When the cable tray 3 is installed on the leveling component 4, the adjusting plane 41 and the abutment plane are tightly abutted and fitted together. This design ensures that the cable tray 3 remains horizontal during installation, thereby improving the quality and reliability of cable laying. Optionally, the leveling component 4 can adopt a prefabricated block structure with multiple angles. During actual installation, the appropriate angle of the leveling component 4 can be selected according to the horizontal deviation of the on-site installation. The leveling component 4 can be made of high-strength steel or other materials to ensure its durability and stability during long-term use. If the prefabricated angle still cannot meet the leveling requirements, the angle of the leveling component 4 can be further adjusted by simple on-site processing and grinding to meet the on-site installation requirements. Through the combined use of the above-mentioned technical means, the rooftop photovoltaic cable laying device 100 of this embodiment not only improves installation efficiency, but also effectively solves the problems of poor reliability and easy damage to cables and trunking in traditional laying methods, providing more reliable technical support for the development of the rooftop distributed photovoltaic industry.

[0045] Further, please refer to Figure 5 In one embodiment of the present invention, the cable tray 3 includes a bottom box 31 and a cover 32. The bottom box 31 has a receiving groove 31a for accommodating cables. The cover 32 is detachably connected to the bottom box 31 and closes the opening of the receiving groove 31a. The bottom box 31 is detachably connected to the crossbeam 2.

[0046] In this embodiment, the cable tray 3 is further subdivided into two parts: a base box 31 and a cover 32. The base box 31 has a receiving slot 31a for placing cables. The top of the base box 31 can be inserted into the cover 32 for a detachable connection. The cover 32 can close the opening of the receiving slot 31a, thereby protecting the cables from external environmental influences. Simultaneously, the base box 31 and the crossbeam 2 can also be detachably connected via bolts, facilitating installation and maintenance. This split design not only facilitates cable laying and maintenance but also enhances the protective performance of the cable tray 3.

[0047] Further, please refer to Figure 1 In one embodiment of the present invention, the roof photovoltaic cable laying device 100 further includes a binding member, which is arranged around the bottom box 31 and the box cover 32.

[0048] In this embodiment, the rooftop photovoltaic cable laying device 100 further incorporates binding members to enhance the overall stability of the cable tray 3. The binding members are positioned around the base box 31 and the cover 32, ensuring a more secure connection between them and preventing the cover 32 from loosening or falling off due to external forces, thus better protecting the cables inside the cable tray 3. This design significantly improves the reliability of the cable tray 3 in the face of severe weather conditions or roof vibrations.

[0049] Further, please refer to Figure 6 In one embodiment of this utility model, the binding component is a self-locking stainless steel cable tie 5.

[0050] In this embodiment, the self-locking stainless steel cable tie 5 includes a self-locking head 51 and a cable tie body 52. ​​The self-locking head 51 automatically tightens the cable tie body 52 after it passes through, achieving a lock without the need for additional fixing devices, ensuring the cable tie body 52 will not loosen and thus providing a stable binding force. Stainless steel is characterized by high strength, corrosion resistance, and good weather resistance, enabling long-term use in harsh environmental conditions such as humidity, high temperatures, or ultraviolet radiation, ensuring the durability and reliability of the cable tie. The self-locking stainless steel cable tie 5 can be adjusted according to the actual size of the cable tray 3, ensuring the cable tie fits tightly against the bottom box 31 and the cover 32, providing a uniform binding force.

[0051] By using self-locking stainless steel cable ties 5, the overall stability of the cable tray 3 can be effectively enhanced. The fastening effect of the cable ties ensures a more secure connection between the bottom box 31 and the cover 32, preventing the cover 32 from loosening or falling off due to external forces, thus better protecting the cables inside the cable tray 3. The adjustability of the stainless steel cable ties 5 allows them to adapt to cable trays 3 of different sizes, improving the versatility and flexibility of the device. The corrosion resistance and weather resistance of stainless steel allow the cable ties to be used for a long time in harsh environmental conditions, reducing the frequency of maintenance and replacement, and lowering operating costs.

[0052] Further, please refer to Figure 5 In one embodiment of the present invention, the cable tray 3 further includes a first elastic sealing member, which is disposed on the inner wall of the cover 32 and arranged along the extension direction of the cover 32, and the first elastic sealing member elastically abuts against the outer wall of the bottom box 31; and / or, the cable tray 3 further includes a second elastic sealing member, which is disposed on the outer wall of the bottom box 31 and arranged along the extension direction of the bottom box 31, and the second elastic sealing member elastically abuts against the inner wall of the cover 32.

[0053] In this embodiment, in order to prevent moisture, dust and other impurities from entering the inside of the tray, a first elastic seal and a second elastic seal are added to protect the cable from the influence of the external environment.

[0054] Specifically, the first elastic seal is located on the inner wall of the cover 32 and extends along the direction of the cover 32. Its main function is to elastically abut against the outer wall of the bottom box 31, thereby forming a seal between the cover 32 and the bottom box 31. The first elastic seal is made of highly elastic and weather-resistant rubber material, possessing excellent sealing performance and anti-aging capabilities. It is elongated in shape and fits tightly against the inner wall of the cover 32 to ensure a good seal. During installation, the first elastic seal, through its elastic deformation, fits tightly against the outer wall of the bottom box 31, forming an effective sealing layer.

[0055] The second elastic seal is located on the outer wall of the base box 31 and extends along the direction of the base box 31. Its main function is to form an elastic contact with the inner wall of the cover 32, further enhancing the sealing effect. The second elastic seal is also made of highly elastic and weather-resistant rubber material, possessing excellent sealing performance and anti-aging capabilities. It is elongated in shape and fits tightly against the outer wall of the base box 31 to ensure a good seal. During installation, the second elastic seal, through its elastic deformation, fits tightly against the inner wall of the cover 32, forming an effective sealing layer.

[0056] Further, please refer to Figure 1 , Figure 2 and Figure 3 In one embodiment of the present invention, a first through hole is formed on the first clamping member 11 and a second through hole is formed on the second clamping member 12; the mounting fixture 1 further includes a bolt assembly 6, which passes through the first through hole and the second through hole in sequence and connects the first clamping member 11 and the second clamping member 12.

[0057] In this embodiment, the bolt assembly 6 includes a bolt and a nut. The diameter and length of the bolt are designed according to the dimensions of the first and second through holes to ensure that the bolt can pass smoothly through both through holes and has sufficient slack to mate with the nut. The nut is made of a high-strength material to ensure a secure connection. The material selection for the bolt assembly 6 is consistent with that of the first clamping member 11 and the second clamping member 12, using high-strength aluminum alloy or stainless steel to ensure corrosion resistance and durability.

[0058] The use of bolt assembly 6 provides higher connection strength. Compared with traditional snap-fit ​​or hinged connections, bolted connections can withstand greater tensile and shear forces, ensuring the stability of the installation clamp 1 during long-term use. The detachability of bolt assembly 6 makes maintenance and replacement of the installation clamp 1 more convenient. When it is necessary to replace or repair the clamp, simply loosen the bolts to quickly disassemble the first clamping member 11 and the second clamping member 12 for the corresponding operation. Through the connection of bolt assembly 6, the structure of the entire installation clamp 1 is more stable, effectively able to withstand the weight of the cable tray 3 and the influence of external environmental factors, improving the reliability and durability of the entire rooftop photovoltaic cable laying device 100.
