Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and particularly relates to a photovoltaic system. Background Art

[0002] With the increasing global emphasis on renewable energy and the growing demand for low-carbon transformation in the transportation field, how to efficiently utilize solar energy resources on transportation infrastructure has become a research hotspot, and transportation energy integration technology has emerged. Installing photovoltaic facilities on the slopes of highways is a typical application of energy integration.

[0003] Currently, photovoltaic modules on highway slopes are usually installed with pressing blocks. When installing the pressing blocks, screws need to be repeatedly tightened and adjusted. The installation process is complex, the installation progress is slow, the installation efficiency is low, and the consumption of installation materials is large. Moreover, there is a certain gap between the pressing blocks and the photovoltaic modules, and rainwater is likely to flow down from the gap when the photovoltaic modules are installed on the highway slope, which impacts the photovoltaic support and shortens the service life of the installation bracket for the photovoltaic modules. In addition, as Figure 5 shown, traditional photovoltaic modules adopt a "field" - shaped installation method, and the junction box is set in the middle of the photovoltaic module. The wiring cables between the photovoltaic modules are long, and the material cost is high. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a photovoltaic system with a simple and stable structure, a simple installation process, and a long service life.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A photovoltaic system includes a plurality of photovoltaic modules, and further includes an installation mechanism. Adjacent photovoltaic modules are connected through the installation mechanism to combine the plurality of photovoltaic modules;

[0007] The installation mechanism includes a cross beam and installation frames connected to both sides of the cross beam. The installation frame includes a frame body, and a first card slot is provided on the frame body for clamping one side edge of the photovoltaic module in the frame body. A waterproof cover plate is provided on at least one side of the first card slot, and the waterproof cover plate overlaps on the first card slot on the other side.

[0008] As a further improvement of the above technical solution:

[0009] Clamping parts are provided on both sides of the cross beam, and a second card slot is further provided on the frame body. The clamping parts are clamped in the second card slot.

[0010] The cross beam is U - shaped, and the clamping parts are provided at both ends of the U - shaped cross beam.

[0011] The first card slot is located at the upper part of the frame, and the second card slot is located at the lower part of the frame.

[0012] A plurality of the photovoltaic modules are arranged in an inclined manner.

[0013] The upper surface of the photovoltaic module is provided with a hydrophobic coating.

[0014] The photovoltaic system further comprises a self-cleaning mechanism, wherein the self-cleaning mechanism comprises a water collecting tank, and the water collecting tank is located below the photovoltaic assembly at the bottom.

[0015] The self-cleaning mechanism also includes a spray device, which is used to extract water from the water collection tank to spray and clean the photovoltaic components.

[0016] A junction box is provided below the long side of the photovoltaic assembly, the long side of the photovoltaic assembly is clamped in the first clamping slot, and a plurality of photovoltaic assemblies are combined in the longitudinal direction.

[0017] The photovoltaic system also includes a frame arranged below the photovoltaic assembly, and the crossbeam is detachably connected to the frame.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The photovoltaic system of the present invention adopts the installation frame clamping method instead of the pressing block for installation, so the installation process is simple and the installation efficiency is high. Compared with the pressing block installation, the structure of the installation frame is simple. When the installation frame is clamped with the photovoltaic module, there is no need to use bolts and other fasteners for secondary fastening, and the amount of installation material used is small. After multiple photovoltaic modules are clamped with the installation frame, they are combined through the crossbeam, and the structure is simple and stable. Since the photovoltaic modules are combined and connected by the installation mechanism, there is a gap for arranging the crossbeam between adjacent photovoltaic modules. By arranging a waterproof cover plate overlapped on the first clamping groove on both sides of the crossbeam, it can prevent moisture penetration, reduce the impact of rainwater, and extend the service life of the photovoltaic system.

[0020] 2. In the photovoltaic system of the present invention, the U-shaped crossbeam is connected to the installation frames on both sides, the load is evenly distributed, and the structure is stable.

[0021] 3. The photovoltaic system of the present invention has multiple photovoltaic modules arranged obliquely, and with the sealing effect of the waterproof cover plate, rainwater on the multiple photovoltaic modules can flow downstream and drain to the bottom, preventing rainwater accumulation and achieving better anti-seepage performance.

[0022] 4. In the photovoltaic system of the present invention, the hydrophobic coating helps rainwater to carry away dust and stains deposited on the surface of the photovoltaic module during its flow, thereby achieving self-cleaning.

[0023] 5. The photovoltaic system of the present invention collects rainwater through a water collection tank, and the collected rainwater is utilized by a spraying device to spray and clean the photovoltaic modules, and a hydrophobic coating is combined to achieve double self-cleaning.

[0024] 6. In the photovoltaic system of the present invention, compared with the "field" - shaped combination method of photovoltaic modules, in this embodiment, the long sides of multiple photovoltaic modules are connected and combined longitudinally. The junction box can be wired along the short side of the photovoltaic module, with short wiring cables and low material costs. Among them, the horizontal direction is the long side direction of the photovoltaic module, and the vertical direction is the short side direction of the photovoltaic module.

[0035] like Figures 1 to 4 As shown, the photovoltaic system of this embodiment includes a plurality of photovoltaic modules 1 and a mounting mechanism 2. Adjacent photovoltaic modules 1 are connected by the mounting mechanism 2 to combine the plurality of photovoltaic modules 1.

[0036] The mounting mechanism 2 includes a crossbeam 21 and a mounting frame 22 connected to both sides of the crossbeam 21. The mounting frame 22 includes a frame body 221. The frame body 221 is provided with a first card slot 222 for clamping one side of the photovoltaic component 1 in the frame body 221. A waterproof cover plate 23 is provided on the first card slot 222 on at least one side, and the waterproof cover plate 23 is overlapped on the first card slot 222 on the other side.

[0037] In the photovoltaic system of this embodiment, when installing, the two opposite sides of the photovoltaic assembly 1 are inserted into the first slots 222 of the two mounting mechanisms 2, so that the photovoltaic assembly 1 can be installed and fixed. The two mounting frames 22 of the mounting mechanism 2 are respectively connected with the two photovoltaic assemblies 1, so that a combination of multiple photovoltaic assemblies 1 can be realized. The photovoltaic system of this embodiment adopts the mounting frame 22 to replace the pressing block for installation, so the installation process is simple and the installation efficiency is high. Compared with the pressing block installation, the mounting frame 22 has a simple structure. When the mounting frame 22 is connected with the photovoltaic assembly 1, it is not necessary to use fasteners such as bolts for secondary fastening, and the amount of installation materials used is small. After the multiple photovoltaic assemblies 1 are connected with the mounting frame 22, they are combined by the crossbeam 21, and the structure is simple and stable. Since the photovoltaic assemblies 1 are combined and connected by the mounting mechanism 2, there is a gap between the adjacent photovoltaic assemblies 1 for arranging the crossbeam 21. By setting the waterproof cover plate 23 overlapped on the first slots 222 on both sides of the crossbeam 21, it can prevent moisture penetration, reduce the impact of rainwater, and prolong the service life of the photovoltaic system.

[0038] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, both sides of the crossbeam 21 are provided with a clamping portion 211, and the frame 221 is also provided with a second clamping groove 223, and the clamping portion 211 is clamped in the second clamping groove 223. The crossbeam 21 and the frame 221 are also connected by clamping, which is convenient for installation and disassembly. During installation, the photovoltaic module 1 is first clamped with the installation frame 22, a crossbeam 21 is fixed, the installation frame 22 on one side of the photovoltaic module 1 is clamped with the crossbeam 21, and then the next crossbeam 21 is pre-installed (not locked and fixed), and the next crossbeam 21 is rotated and adjusted so that the installation frame 22 on the other side of the photovoltaic module 1 is clamped with the next crossbeam 21. Repeat the same steps to achieve the rapid assembly and installation of multiple photovoltaic modules 1.

[0039] Furthermore, if Figure 2 As shown, in this embodiment, the cross beam 21 is U-shaped, and the clamping parts 211 are arranged at both ends of the U-shaped cross beam 21. The U-shaped cross beam 21 is connected to the mounting frames 22 on both sides, the load is evenly distributed, and the structure is stable.

[0040] Furthermore, in this embodiment, the first slot 222 is located at the upper part of the frame 221, and the second slot 223 is located at the lower part of the frame 221. After the photovoltaic module 1 is inserted into the first slot 222, the frame 221, the second slot 223, and the beam 21 connected to the second slot 223 can all be located below the photovoltaic module 1, with a compact structure and a reasonable layout.

[0041] Furthermore, if Figure 2 and Figure 3 As shown, in this embodiment, multiple photovoltaic modules 1 are arranged in an inclined structure. The multiple photovoltaic modules 1 arranged in an inclined manner, with the sealing effect of the waterproof cover plate 23, rainwater on the multiple photovoltaic modules 1 can flow down and drain to the bottom, preventing rainwater from accumulating and achieving better anti-seepage performance.

[0042] Furthermore, in this embodiment, a hydrophobic coating is provided on the upper surface of the photovoltaic module 1. The hydrophobic coating helps rainwater to carry away dust and stains deposited on the upper surface of the photovoltaic module 1 during its flow, thereby achieving self-cleaning.

[0043] Furthermore, in this embodiment, if Figure 3 As shown, the photovoltaic system also includes a self-cleaning mechanism 4, which includes a water collection tank 41 and a spray device 42. The water collection tank 41 is located below the photovoltaic module 1 at the bottom, and the spray device 42 is used to extract water from the water collection tank 41 to spray and clean the photovoltaic module 1. Rainwater is collected by the water collection tank 41, and the spray device 42 uses the collected rainwater to spray and clean the photovoltaic module 1, and cooperates with the hydrophobic coating to achieve double self-cleaning.

[0044] In this embodiment, the angle of the spraying device 42 can be automatically and flexibly adjusted. When not in use, the spraying pipeline can be telescoped and folded to avoid forming a shelter and affecting the power generation efficiency of the photovoltaic module 1. The spraying device 42 can control the spraying amount and spraying time to reduce the waste of water resources.

[0045] Further, as Figure 4 shown, in this embodiment, a junction box (not shown in the figure) is provided below the long side of the photovoltaic module 1. The long side of the photovoltaic module 1 is clamped in the first card slot 222, and multiple photovoltaic modules 1 are combined longitudinally. Compared with the "field" - shaped combination method of the photovoltaic modules 1, in the way that the long sides of multiple photovoltaic modules 1 in this embodiment are joined and combined longitudinally, the junction box can be wired along the short side of the photovoltaic module 1. The wiring cable is short and the material cost is low. Especially when installed on a long slope, the cable length can be reduced by about 20%. Moreover, in the combination method of this embodiment, a narrower area can also be utilized, the number of single - string blocks of the photovoltaic module 1 increases, and the power generation power is greater. Among them, the horizontal direction is the long - side direction of the photovoltaic module 1, and the vertical direction is the short - side direction of the photovoltaic module 1.

[0046] Further, in this embodiment, the photovoltaic system further includes a frame 3 provided below the photovoltaic module 1, and the cross - beam 21 is detachably connected to the frame 3. The combined multiple photovoltaic modules 1 are installed on the frame 3 through the cross - beam 21. The frame 3 can be installed in different scenarios such as a high - speed slope, and the structure is stable. Preferably, in this embodiment, the cross - beam 21 is threadedly connected to the frame 3, and the cross - beam 21 is installed on the frame 3 through the connecting bolt 212, with a simple and stable structure.

Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention by using the above - disclosed methods and technical contents, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the technical solution of the present invention still fall within the scope of the protection of the technical solution of the present invention.
