Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of photovoltaic power plant operation and maintenance channels, and in particular to a photovoltaic power plant operation and maintenance channel integrated with a cable tray. Background Technology
[0002] Traditional rooftop photovoltaic (PV) power generation systems typically involve installing photovoltaic panels on the roof of a building to generate electricity from sunlight. Before installing the PV panels, walkways must be constructed on the roof to serve as platforms for subsequent installation and maintenance, preventing workers from directly stepping on the roof and causing structural damage. Cable trays must also be installed on one side of the walkways to store and manage the PV panel cables, ensuring efficient power transmission and preventing environmental corrosion of the cables.
[0003] For example, Chinese utility model patent CN220440336U discloses a photovoltaic cable channel for a corrugated steel roof, including a connecting cylinder, a cable tray, and a base. Cable trays are inserted into the front and rear sides of the connecting cylinder, and the bottom surface of the connecting cylinder is slidably connected to the base. The base is fixedly connected to the corrugated steel roof. Power cables and cleaning pipes are placed inside the cable tray. This utility model, through its modular installation structure, facilitates initial installation and subsequent maintenance. Its layered structure allows cleaning pipes and cables to be collected in the same cable tray. However, the connection between the base and the roof is only achieved through connecting grooves and connecting rails, which are insufficient to withstand large loads. Separate maintenance channels and cable trays need to be built, consuming significant manpower and resources, and increasing the construction cost of the power station. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stable and easy-to-install integrated photovoltaic power station operation and maintenance channel with cable trays.

[0006] Further, the fixture member includes a first clamping plate fixedly connected to the guide rail, a second clamping plate hinged to the first clamping plate, and a compression screw for connecting the first clamping plate and the second clamping plate. A clamping cavity is formed at the lower end of the second clamping plate, and clamping teeth are formed at the lower end of the first clamping plate. The clamping cavity and the clamping teeth cooperate to clamp and fix the roof. Tightening teeth that fit the lower surface of the guide rail are formed on the upper surface of the first clamping plate.
[0007] Further, the bottom of the bridge is fixedly connected to the corresponding guide rail by screws, and the outer walls on both sides of the bridge are in close fit with the support frame.
[0008] Further, the support frame is provided with a support plate and two fixing plates. Each fixing plate is fixedly connected to a corresponding end of the support plate, and each fixing plate is fixedly connected to the corresponding guide rail. The upper surface of the support plate is fixedly connected to the cover plate.
[0009] Further, the support plate is in a "U" shape.
[0010] Further, a plurality of reinforcing grooves are equidistantly arranged on the cover plate. The lower surface of each reinforcing groove is in contact with the support plate, and each reinforcing groove is fixedly connected to the support plate by bolts. A plurality of anti-slip embossments are arranged on the upper surface of the cover plate.
[0011] Further, the cover plate is in the shape of a city wall.
[0012] The beneficial effects of the present utility model are as follows: The present utility model adopts a nested design of the bridge and the support frame, integrating the operation and maintenance passage and the cable bridge, reducing the materials and installation costs required for independent setting, and at the same time reducing the later maintenance cost. The fixture member, the bridge, the support frame and the cover plate are mainly fixedly connected by bolts.

[0020] like Figures 1 to 2 As shown, in this embodiment, the present invention includes several clamping components 2, all fixedly connected to the roof 1; several guide rails 3, equally spaced above the roof 1, each guide rail 3 corresponding to two sets of horizontally arranged clamping components 2 fixedly connected; a cable tray 4, the lower end of which is fixedly connected to several guide rails 3 for laying electrical wires; a support frame 5, sleeved above the cable tray 4, with both sides of the support frame 5 fixedly connected to several guide rails 3; and a cover plate 6, fixedly connected above the support frame 5 for supporting stepping.
[0021] Specifically, the clamp 2 is connected and fixed to the roof 1 by clamping screws 23. The clamps are evenly spaced on the roof 1. Each guide rail 3 is connected and fixed to two clamps 2 by bolts. The clamp 2 ensures the stable installation of the guide rail 3. The guide rail 3 provides reliable support for the cable tray 4, enabling the cable tray 4 to lay cables stably. At the same time, the guide rail 3 is made of aluminum alloy, which has the advantages of light weight and corrosion resistance, reducing the overall weight and maintenance cost of the system. The cover plate 6 is made of specially treated profiled steel plate, which is made of GD350-ZM275. Combined with the wall-like structure design, it has high support rigidity and serves as both the cover of the cable tray 4 and the bearing surface of the maintenance channel, realizing the integrated design of the maintenance channel and the cable tray.
[0022] The cable tray 4 and support frame 5 are nested together, which integrates the operation and maintenance channel and the cable tray, reducing the material and installation costs required for independent installation, and also reducing the later maintenance costs. The clamp 2, cable tray 4, support frame 5 and cover plate 6 are mainly fixed by bolts. The connection between each component is firm, the installation is simple and efficient, the stress is reasonable, the overall stability of the system is improved, and the occurrence of failures caused by structural instability is reduced.
[0023] like Figure 3As shown, in this embodiment, the fixture member 2 includes a first clamping plate 21 fixedly connected to the guide rail 3, a second clamping plate 22 hinged to the first clamping plate 21, and a pressing screw 23 for connecting the first clamping plate 21 and the second clamping plate 22. A clamping cavity 24 is formed at the lower end of the second clamping plate 22, and a clamping tooth 25 is formed at the lower end of the first clamping plate 21. The clamping cavity 24 and the clamping tooth 25 cooperate to clamp and fix the roof 1. A fitting tooth 26 that fits the lower surface of the guide rail 3 is formed on the upper surface of the first clamping plate 21.
[0024] Specifically, the fixture member 2 is a standing seam clamp. There are two groups of pressing screws 23, and each group is an M8 bolt. The connecting bolt between the first clamping plate 21 and the guide rail 3 is M8*25, and flat washers, elastic washers and nuts are provided.
[0025] As Figures 1 to 2 shown, in this embodiment, the bottom of the bridge 4 is fixedly connected to the corresponding guide rail 3 by screws, and the outer walls on both sides of the bridge 4 are in tight fit with the support frame 5.
[0026] Specifically, the bridge 4 is fixed by screws, which simplifies the installation process and facilitates the laying of cable circuits.
[0027] As Figure 5 shown, in this embodiment, the support frame 5 is provided with a support plate 51 and two fixing plates 52. Each fixing plate 52 is fixedly connected to a corresponding end of the support plate 51, and each fixing plate 52 is fixedly connected to the corresponding guide rail 3. The upper surface of the support plate 51 is fixedly connected to the cover plate 6.
[0028] Specifically, the support plate 51 is the main load-bearing carrier. The inner side wall of the support plate 51 is in tight fit with the outer side wall of the bridge 4 to enhance the connection strength and further improve the support force.
[0029] In this embodiment, the support plate 51 is in a "U" shape.
[0030] As Figure 6 shown, in this embodiment, the cover plate 6 is provided with a number of reinforcing grooves 61 at equal intervals. The lower surface of each reinforcing groove 61 is in fit with the support plate 51, and each reinforcing groove 61 is fixedly connected to the support plate 51 by bolts. The upper surface of the cover plate 6 is provided with a number of anti-slip embossments 62.
[0031] Specifically, the cover plate 6 has high strength and stiffness through a special profiled structure. It can not only serve as the upper cover of the bridge 4 to protect the cables, but also serve as the bearing surface of the operation and maintenance passage to bear the walking load of personnel.
[0032] In this embodiment, the cover plate 6 is in a city wall shape.
[0033] The working principle of this utility model:
[0034] Multiple clamping components 2 are clamped and fixed to the roof 1 at their lower ends. The guide rail 3 is installed on the upper end of the corresponding clamping component 2 by bolts. The cable tray 4 is fixed on the guide rail 3. The support frame 5 is sleeved on the top of the cable tray 4. Together with the cover plate 6 fixed on the top, a stable integrated system for supporting the cable tray 4 and providing a maintenance channel is formed.
[0035] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
