Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic bridge installation, in particular to a bridge installation structure in a square array of a rooftop distributed photovoltaic power station. Background Art

[0002] Photovoltaic power generation is an industry that uses solar energy to generate electricity. By converting solar energy into electrical energy, it provides clean energy and renewable energy, which has important economic, social and environmental significance. In addition to important factors such as solar energy intensity and photovoltaic components that affect power generation efficiency, the transmission of electricity is also very important. As the main carrier of cables, photovoltaic bridges play a vital role in the entire photovoltaic system and are an indispensable part of the photovoltaic power generation system. It can not only ensure the stability and safety of photovoltaic components, but also make the entire system more tidy and beautiful, and improve the efficiency and economic value of photovoltaic power generation. The importance of bridges cannot be ignored.

[0003] At present, many rooftop distributed photovoltaic projects adopt the installation method of placing photovoltaic bridges directly above the purlins. Although this installation method is simple to construct, it will affect the walking of the cleaning robot equipment and increase the risk of downtime of the cleaning robot equipment. When the cleaning robot equipment of the photovoltaic power station is running, the height difference between the photovoltaic module array and the photovoltaic bridge will cause the cleaning robot equipment to stop when climbing the slope. This problem occurs frequently on site, greatly increasing the workload of operation and maintenance.

[0004] To this end, the present application designs a bridge installation structure within a square array of a rooftop distributed photovoltaic power station to solve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] Figure 1-Figure 5This is a specific embodiment of the utility model, which is a bridge installation structure in a rooftop distributed photovoltaic power station array. The photovoltaic bridge of this embodiment is installed below the photovoltaic module array, and is fastened with a bridge support plate and purlins. The bridge support plate plays the role of fixing the bridge and sharing the weight of the cables, and the support plate and the purlins are firmly connected by welding. The novelty of the photovoltaic bridge is that circular holes are set on the side to increase the heat dissipation capacity inside the bridge. Partitions are added inside the bridge, and the partitions are fixed on the bottom plate of the bridge by welding to distinguish the cable laying positions of different arrays. Photovoltaic modules are arranged above the purlins, and the height of the entire array above the modules is consistent. When the photovoltaic cleaning equipment is running, it does not affect the movement of the equipment.

[0023] As shown in the figure, circular holes are evenly arranged on the side of the photovoltaic bridge 1, and a partition 2 is added in the middle part of the bridge 1 to distinguish the square array cables on both sides for easy maintenance. The photovoltaic bridge 1 is mainly fixedly connected to the purlin 3 through the bridge support plate 5 and is suspended below the purlin 3. The connection method can be welding connection or bolt connection. Circular holes are evenly arranged on the surface of the partition 2 for heat dissipation. The partition and the photovoltaic bridge are connected by spot welding and fixed, and anti-corrosion treatment is performed after tightening.

[0024] Waist-shaped bolt holes are evenly distributed on the purlin 3, and the purlin 3 and the roof 6 are fixed by a clamp 4, and the fixing method is bolt fastening. The clamp 4 is mainly used to connect the roof and the purlin 3, and the connection is fastened by bolts. Its characteristic is that the clamp 4 adopts a heightened design. The bridge support plate 5 is designed in the form of a groove, and the bridge is placed inside the groove. The bridge support plate is firmly connected to the purlin 3 by welding using a fixing piece 7, and anti-corrosion treatment is performed after fixing.

[0025] Photovoltaic bridge 1 has strong heat dissipation. Adding small circular holes on both sides of the bridge can enhance the heat dissipation function. The cable will heat up sharply during normal operation. Adding small circular holes can increase air circulation and reduce the temperature inside the bridge, thereby optimizing the working environment of the cable and improving the power generation efficiency of the power station. The use function of the bridge itself is guaranteed and the performance of the entire photovoltaic power station is optimized.

[0026] In this embodiment, the photovoltaic bridge is installed under the purlin to keep the upper plane of the photovoltaic array consistent, avoiding the disadvantage of the cleaning robot equipment running on the component shutting down due to climbing problems, increasing the service life of the cleaning robot and reducing the number of operation and maintenance inspections.

[0027] The bridge support plate 5 is welded to the purlin, which is more firm and more convenient to construct. The bridge support plate 5 itself has a certain supporting capacity, which can assist the photovoltaic bridge to bear the weight of the cable and reduce the deformation of the photovoltaic bridge.

[0028] The overall installation structure of the photovoltaic bridge 1 is below the photovoltaic modules, which reduces the exposure of the cables to sunlight, further reduces the operating temperature of the cables in the entire array, and reduces the probability of accidents caused by overheating of the cables.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
