Description

Technical Field

[0002] At present, photovoltaic power stations fix photovoltaic modules on the bracket by top installation (using fixings such as middle pressure blocks) or side installation (using fixings such as side pressure blocks), so there is a certain distance between photovoltaic modules. The current waterproofing measures are to install a horizontal water tank under the gap between two adjacent photovoltaic modules in the horizontal direction, and install a main water tank under the gap between two adjacent photovoltaic modules in the vertical direction. The water flow in the horizontal water tank will be collected and flowed out into the main water tank.

[0003] However, due to the height difference and gap between the water tank and the photovoltaic module, when encountering heavy rain, the water flow is too large, the water volume at the intersection of the horizontal water tank and the main water tank surges, and the flow rate increases, causing water to splash or overflow from the main water tank, and flow from the gap between the main water tank and the photovoltaic module to the bottom of the bracket, thus causing water leakage in the photovoltaic power station.

[0040] The utility model provides a photovoltaic power station 10.

[0041] See also Figure 1 In one embodiment of the utility model, the photovoltaic power station 10 includes a plurality of photovoltaic modules 200 and a mounting bracket 100, the mounting bracket 100 includes a plurality of first beams 110, the photovoltaic modules 200 are mounted on the first beams 110, the upper surface of the first beams 110 is provided with a drainage groove 113, and the two side surfaces of the first beams 110 in the width direction of the drainage groove 113 are respectively abutted against different photovoltaic modules 200.

[0042] Specifically, the photovoltaic power station 10 is a green energy facility that converts solar energy into electrical energy, and mainly includes a photovoltaic module 200 (solar panel), a mounting bracket 100, and a series of supporting systems, such as an inverter, a power distribution cabinet, a monitoring system, etc. Among them, the photovoltaic module 200 is the energy conversion unit in the photovoltaic power station 10, and is mainly composed of solar cells, packaging materials, glass panels, frames, and junction boxes. The mounting bracket 100 is a basic structure that supports and fixes the photovoltaic module 200. The material of the mounting bracket 100 is mostly aluminum alloy or stainless steel with good corrosion resistance to ensure that the structure of the mounting bracket 100 is safe and stable.

[0043] The mounting bracket 100 is a supporting structure for supporting and fixing the photovoltaic assembly 200, and can be a horizontal beam or a longitudinal beam. A drainage groove 113 is provided on the upper surface of the first beam body 110, and rainwater can be drained along the extension direction of the drainage groove 113. In the width direction of the drainage groove 113, photovoltaic assemblies 200 are provided on both sides of the first beam body 110. Since the two side surfaces of the first beam body 110 in the width direction of the drainage groove 113 are respectively abutted against the corresponding photovoltaic assemblies 200, the side surfaces of the first beam body 110 and the photovoltaic assemblies 200 are tightly connected, thereby eliminating the gap formed in the height direction between the first beam body 110 and the photovoltaic assemblies 200, and the rainwater in the drainage groove 113 cannot splash out of the drainage groove 113 from the gap between the first beam body 110 and the photovoltaic assemblies 200 in the height direction. Even in heavy rain weather, the rainfall increases sharply, and it can effectively prevent rainwater from splashing from the gap to the bottom of the mounting bracket 100, thereby preventing rain from leaking under the mounting bracket 100, thereby improving the anti-leakage performance of the photovoltaic power station 10.

[0044] The technical solution of the present invention eliminates the gap formed between the two in the height direction by abutting the side of the first beam 110 against the photovoltaic component 200, thereby preventing rainwater from splashing from the gap to the bottom of the mounting bracket 100, thereby improving the anti-leakage performance of the photovoltaic power station 10.

[0045] In one embodiment, a plurality of first beams 110 are spaced apart along a first direction, the first beams 110 extend along a second direction and form an angle with a horizontal plane, and the drainage grooves 113 extend along the second direction; between every two adjacent first beams 110, a plurality of photovoltaic components 200 are connected in sequence along the second direction, and a water-proof structure is provided at the connection between every two adjacent photovoltaic components 200.

[0046] The upper surface of the first beam 110 is provided with a drainage groove 113 extending in the second direction, so that rainwater can be directly discharged in the drainage groove 113 along the second direction. On the one hand, since the two side surfaces of the first beam 110 in the width direction of the drainage groove 113 are respectively in contact with the corresponding photovoltaic module 200, the rainwater in the drainage groove 113 cannot splash out of the drainage groove 113 from the gap between the first beam 110 and the photovoltaic module 200 in the height direction; on the other hand, since the influx of rainwater from the first direction is reduced, the flow rate and flow velocity of rainwater in the drainage groove 113 are avoided to surge, and the risk of rainwater splashing under the mounting bracket 100 is reduced, thereby improving the anti-leakage performance of the photovoltaic power station 10. In addition, there is no need to set a water groove extending in the first direction, which simplifies the overall structure of the mounting bracket 100 and reduces the production cost.

[0047] At the same time, the photovoltaic modules 200 are orderly installed between two adjacent first beams 110, and the extension direction and distribution direction of the panel of the photovoltaic modules 200 are the same. In the second direction, the connection between each two adjacent photovoltaic modules 200 is provided with a water-proof structure, which can prevent rainwater from leaking from the connection between the two adjacent photovoltaic modules 200 to the bottom of the mounting bracket 100. Therefore, the photovoltaic modules 200 abut against the side of the first beam 110 in the first direction, thereby preventing the photovoltaic power station 10 from leaking in the first direction due to splashing of rainwater in the drainage groove 113; the photovoltaic modules 200 are provided with a water-proof structure at the connection between the two adjacent photovoltaic modules 200 in the second direction, thereby preventing the photovoltaic power station 10 from leaking in the second direction due to rainwater leaking from the connection, so that the risk of water leakage of the photovoltaic power station 10 can be effectively reduced in both the first direction and the second direction, thereby further improving the water-proof performance of the photovoltaic power station 10.

[0048] The anti-leakage structure may be formed by coating waterproof glue at the connection between two adjacent photovoltaic modules 200, or by providing waterproof ribs at the connection.

[0049] In one embodiment, the photovoltaic assembly 200 includes a photovoltaic panel and a frame arranged around the photovoltaic panel, the frame includes a first frame portion 210 and a second frame portion 220 connected to each other, the edge of the first frame portion 210 protrudes from the edge of the second frame portion 220 and abuts against the edge of the notch of the drainage groove 113, and the side wall surface of the first beam body 110 abuts against the second frame portion 220.

[0050] See also Figure 3The photovoltaic assembly 200 includes a photovoltaic panel and a frame. The frame is mostly made of metal materials such as aluminum and aluminum alloy to provide greater mechanical strength to protect the edge of the photovoltaic panel and facilitate installation and fixing. The photovoltaic panel is provided with a first frame 210 and a second frame 220 on two opposite sides in the first direction, and the first frame 210 and the second frame 220 extend along the second direction. The first frame 210 abuts against the upper surface of the first beam 110 and the edge of the notch of the drainage groove 113, and the second frame 220 abuts against the side wall of the first beam 110, thereby increasing the abutment area between the frame and the first beam 110, which not only further reduces the risk of rainwater splashing or overflowing from the gap between the first beam 110 and the photovoltaic assembly 200, but also improves the stability and reliability of the connection between the photovoltaic assembly 200 and the first beam 110.

[0051] In one embodiment, the mounting bracket 100 further includes a sealing layer 140 disposed between the first frame portion 210 and the edge of the notch of the drain groove 113 to seal the gap between the first frame portion 210 and the edge of the notch of the drain groove 113 .

[0052] See also Figure 3 By providing a sealing layer 140 between the first frame 210 and the edge of the notch of the drain groove 113, rainwater can be further prevented from penetrating from the gap between the first frame 210 and the edge of the notch of the drain groove 113, thereby further improving the anti-leakage effect of the photovoltaic power station 10. The sealing layer 140 can be made of a material with good sealing effect such as a rubber pad, or can be filled with waterproof glue.

[0053] In one embodiment, a receiving groove is provided at the edge of the notch of the drainage groove 113 , and the sealing layer 140 is disposed in the receiving groove. The upper surface of the sealing layer 140 is flush with the notch of the drainage groove 113 .

[0054] See also Figure 3 The edge of the notch of the drainage groove 113 is provided with a receiving groove, which is used to receive the sealing layer 140, thereby improving the stability and reliability of the installation of the sealing layer 140. The upper surface of the sealing layer 140 is flush with the notch of the drainage groove 113, ensuring the tight connection between the sealing layer 140 and the first frame 210, and effectively preventing rainwater from penetrating into the gap between the photovoltaic module 200 and the first beam body 110.

[0055] In one embodiment, the first beam body 110 is fixed to the second beam body 120 by fastening or welding.

[0056] See also Figure 3 and Figure 4The first beam body 110 and the second beam body 120 are fixed by fastening or welding, which ensures the structural stability and strength of the mounting bracket 100, so that it can withstand the weight of the photovoltaic module 200 and the influence of the external environment (wind and rain), ensuring the safe operation and long-term use of the photovoltaic module 200.

[0057] The fastening connection can be fastened together by bolts, screws, rivets or other fasteners to fix the first beam body 110 and the second beam body 120 together, which is not only easy and quick to install, but also convenient for on-site adjustment and later maintenance, and has high flexibility. At the same time, the fastening connection can also effectively absorb certain structural stresses and reduce the deformation caused by thermal expansion and contraction.

[0058] The welding connection can directly weld the first beam body 110 and the second beam body 120 into one body by arc welding, gas shielded welding or other welding techniques. The welding connection has extremely high structural strength and stability, can withstand large loads and external environmental pressure, and is particularly suitable for photovoltaic power stations 10 that are exposed to harsh weather conditions for a long time. The continuous structure formed by the welding connection is conducive to uniform load transmission and reduces local stress concentration.

[0059] In one embodiment, the mounting bracket 100 also includes a connecting member 150, which includes a first connecting portion 151, a second connecting portion 152 and a third connecting portion 153. The first connecting portion 151 and the second connecting portion 152 are connected to opposite ends of the third connecting portion 153 at an angle and extend away from each other; the first connecting portion 151 abuts against the lower surface of the first beam body 110 and is locked with the first beam body 110 by a first fastener, the second connecting portion 152 is locked to the lower surface of the photovoltaic component 200 by a second fastener, and the third connecting portion 153 abuts against the side wall of the first beam body 110.

[0060] See also Figure 3, the connector 150 is used to strengthen the stable connection between the first beam 110 and the photovoltaic assembly 200. The first connecting portion 151 is used to connect the first beam 110, and by cooperating with the first fastener (such as a bolt and a nut combination), the two can be tightly fixed. The second connecting portion 152 is used to be directly connected to the photovoltaic assembly 200, and the photovoltaic assembly 200 is firmly connected to the connector 150 through the second fastener (such as a bolt and a nut combination), which ensures the installation accuracy of the photovoltaic assembly 200 and reduces the displacement caused by vibration or external force. The third connecting portion 153 is used to directly contact or cling to the side wall surface of the first beam 110, which can more accurately locate the position of the first beam 110 and ensure the alignment between the photovoltaic assembly 200 and the first beam 110, so that no additional calibration steps are required during the installation process, because the third connecting portion 153 directly cooperates with the side wall surface of the first beam 110 to naturally guide the photovoltaic assembly 200 into the correct position, thereby simplifying the on-site construction procedures and improving work efficiency.

[0061] In one embodiment, the mounting bracket 100 further includes a support frame 130 and a plurality of second beam bodies 120 extending along the first direction, and the plurality of second beam bodies 120 are spaced apart between the support frame 130 and the first beam body 110 along the second direction.

[0062] See also Figure 4 The mounting bracket 100 strengthens the stability and load-bearing capacity of the entire photovoltaic power station 10 by adding a support frame 130 and a second beam 120. The support frame 130 provides the necessary vertical support and stability to ensure that the photovoltaic module 200 can be firmly installed on the ground or on the roof. By adding a second beam 120 to increase the support structure of the middle level, the rigidity and load distribution capacity of the entire mounting bracket 100 are significantly enhanced. The second beam 120 can effectively disperse the weight and reduce the pressure on the single support point of the support frame 130, especially in large photovoltaic power stations 10, which can better cope with dynamic load changes under different weather conditions and ensure the safe and stable operation of the photovoltaic module 200.

[0063] In another embodiment, the mounting bracket 100 may not be provided with the support frame 130, and the first beam body 110 is installed along the slope or the sloped roof, which is adapted to local conditions, reduces production materials, and reduces production costs. In another embodiment, the mounting bracket 100 may not be provided with the second beam body 120, and the first beam body 110 is directly installed on the support frame 130.

[0064] In one embodiment, the connection between every two adjacent photovoltaic modules 200 is glued together with waterproof glue or sealed with a sealing strip to form a water-proof structure.

[0065] The connection between each two adjacent photovoltaic modules 200 is smoothly connected, and waterproof glue is set at the connection. On the one hand, the connection between the two adjacent photovoltaic modules 200 is tighter and more stable. On the other hand, the gap between the two adjacent photovoltaic modules 200 is filled with waterproof glue, which can effectively prevent rainwater from leaking from the gap and causing water leakage. The waterproof glue can use a silicone-based sealant dedicated to the photovoltaic module 200, which has excellent weather resistance, UV resistance, temperature change resistance, and can adapt to large thermal expansion and contraction.

[0066] A sealing strip can also be provided at the connection of two adjacent photovoltaic modules 200. The sealing strip made of polymer material can be pre-installed on the edge of the photovoltaic module 200. When the photovoltaic module 200 is installed, the sealing strip will be compressed to form a tight seal. Moreover, this method is easy to install and can quickly form a sealing effect. The sealing strip is usually made of elastic material, such as EPDM (ethylene propylene diene monomer rubber), which has good weather resistance and anti-aging properties.

[0067] Furthermore, a built-in waterproof groove may be provided in the frame of the photovoltaic module 200 , and a waterproof glue or a sealing strip may be embedded therein to enhance the waterproof performance of the connection between two adjacent photovoltaic modules 200 .

[0068] In one embodiment, the photovoltaic component 200 includes a photovoltaic panel and a frame arranged at the periphery of the photovoltaic panel, and the frame includes a main body 230 and mating surfaces distributed on the periphery of the main body 230 on opposite sides in the second direction, one of the mating surfaces is provided with a first clip structure 260, and the other mating surface is provided with a second clip structure 270. At the mating point of two adjacent photovoltaic components 200, the two mating surfaces are abutted and matched, the upper side surfaces of the main body 230 of the two frames are smoothly connected, and the first clip structure 260 is engaged with the second clip structure 270.

[0069] See also Figure 5 and Figure 8 The photovoltaic panel is responsible for directly converting sunlight into electrical energy. In order to protect the photovoltaic panel and provide a stable installation interface, a frame is provided around the photovoltaic panel. The frame not only protects the photovoltaic panel, but also realizes the connection between adjacent photovoltaic modules 200.

[0070] Two adjacent photovoltaic modules 200 are engaged with each other through the first engaging structure 260 and the second engaging structure 270, so that the adjacent photovoltaic modules 200 can be quickly, conveniently and firmly connected. The first engaging structure 260 and the second engaging structure 270 can be specifically a mechanism such as a slot and a plug-in portion, a slot and a convex portion, a convex portion and a latch that cooperate with each other, and the adjacent photovoltaic modules 200 can be tightly connected through simple alignment and pressing actions, without the need for additional tools or fasteners, which greatly simplifies the installation process.

[0071] When two adjacent photovoltaic modules 200 are placed on the mounting bracket 100, the first snap-in structure 260 and the second snap-in structure 270 on their frames can be aligned and snapped into each other, so that the upper surface of the photovoltaic module 200 forms a continuous and smooth surface, which not only realizes the limited connection between the photovoltaic modules 200, but also makes the installation of the photovoltaic modules 200 more convenient and quick, greatly improves the installation efficiency, and can effectively reduce the gap between the photovoltaic modules 200, which helps to guide rainwater to flow directly along the second direction, thereby achieving the effect of drainage and waterproofing, and improving the anti-leakage performance of the photovoltaic power station 10.

[0072] The first snap-fitting structure 260 and the second snap-fitting structure 270 are respectively formed on two opposite mating surfaces. At the mating position of two adjacent photovoltaic components 200, the mating surface of one photovoltaic component 200 abuts against the mating surface of the other photovoltaic component 200, and the upper side surfaces 231 of the main body parts of the two frames are smoothly connected.

[0073] See also Figures 8 to 10 During the installation process, the mating surface has a guiding function, and the two mating surfaces of the two adjacent photovoltaic components 200 can slide and cooperate with each other until the first clamping structure 260 of one photovoltaic component 200 is engaged with the second clamping structure 270 of the other photovoltaic component 200. In this way, the photovoltaic component 200 is not only convenient and labor-saving to install, but also can form a limit position of the photovoltaic component 200 in the slope direction. At the same time, the upper side surfaces 231 of the main body of the two frames are smoothly connected, ensuring the close fit of the two frames, which can prevent dust and rainwater from accumulating between the two adjacent photovoltaic components 200, facilitate rapid drainage, and reduce the potential damage caused by water retention, thereby improving the drainage effect of the photovoltaic power station 10.

[0074] In one embodiment, the mating surface extends obliquely relative to the upper surface 231 of the main body.

[0075] See also Figures 8 to 10 The overall structural strength of the frame is better and the pressure bearing capacity is better. Moreover, during the installation process, the sliding fit between the matching surfaces of two adjacent photovoltaic modules 200 is smoother.

[0076] In one embodiment, the mating surface and the photovoltaic assembly 200 are arranged to be inclined upward relative to a horizontal plane in the same direction to form a water-leakage-proof structure.

[0077] See also Fig.10When the mating surface extends obliquely relative to the upper surface 231 of the main body, the mating surface is in the same direction as the photovoltaic module 200 (the same direction here should be understood as along the slope), and the mating surface can be consistent with the second direction or deviate from the second direction, but the overall inclination direction is along the slope. It can be understood that when the photovoltaic module 200 is placed horizontally, the end of the mating surface away from the main body 230 is lower than the other end of the mating surface close to the main body 230; when the photovoltaic module 200 is installed on the mounting bracket 100 and distributed along the second direction, the end of the mating surface away from the main body 230 is higher than the other end of the mating surface close to the main body 230.

[0078] In this way, even if rainwater penetrates into the mating surface from the gap at the connection between the upper surfaces of two adjacent photovoltaic modules 200, since the mating surface is along the slope, the rainwater will flow along the slope due to its own gravity and will not be able to leak from the gap at the connection between the lower surfaces of the two photovoltaic modules 200.

[0079] See also Figure 5 In other embodiments, the mating surface extends parallel to the upper surface 231 of the main body.

[0080] When the mating surface extends parallel to the upper surface 231 of the main body, the mating surface and the photovoltaic assembly 200 extend in the same direction.

[0081] In one embodiment, one of the first locking structure and the second locking structure is a locking groove, and the other is a locking protrusion.

[0082] See also Figure 5 and Fig.10 Between two adjacent first beams 110, a plurality of photovoltaic modules 200 are arranged in sequence along the second direction, and the distribution of the slots and the protrusions can be that the photovoltaic module 200 has a slot at its lower end in the second direction and a protrusion at its upper end in the second direction, the slot of the photovoltaic module 200 is engaged with the protrusion of another photovoltaic module 200 adjacent thereto, and the protrusion of the photovoltaic module 200 is engaged with the slot of another photovoltaic module 200 adjacent thereto.

[0083] The distribution of the slot and the protrusion can also be that the photovoltaic component 200 is provided with a protrusion at the lower end in the second direction, and a slot is provided at the upper end in the second direction, the protrusion of the photovoltaic component 200 is engaged with the slot of another photovoltaic component 200 adjacent thereto, and the slot of the photovoltaic component 200 is engaged with the protrusion of another photovoltaic component 200 adjacent thereto.

[0084] The design of the locking protrusion and the slot between two adjacent photovoltaic components 200 allows the two adjacent photovoltaic components 200 to be quickly installed in a limited position. Not only is the installation quick and the connection stable, but the protrusion itself can also form a waterproof structure, which can block rainwater and further reduce the risk of rainwater leakage from the mating surface.

[0085] In one embodiment, the two mating surfaces that abut against each other include an upper mating surface 240 and a lower mating surface 250 , the locking groove is provided on the upper mating surface 240 , and the locking protrusion is provided on the lower mating surface 250 and is provided on a side away from the corresponding main body 230 .

[0086] See also Figures 8 to 10 , each frame is provided with a mating surface at both ends in the second direction. When the mating surfaces of the frames of two adjacent photovoltaic modules 200 are in contact, the mating surface of the frame of one photovoltaic module 200 is the upper mating surface 240, and the mating surface of the frame of the other photovoltaic module 200 is the lower mating surface 250. The upper mating surface 240 is in contact with the top of the lower mating surface 250. The upper mating surface 240 is provided with a card slot, and the lower mating surface 250 is provided with a card convex. The shape of the card slot matches the card convex of the lower mating surface 250. The card convex and the card slot can fit tightly to prevent dislocation or falling off. The card convex is provided on the lower mating surface 250, which can block rainwater. The card slot is located on the side close to the main body 230, and the card convex is located on the side away from the main body 230. The card slot and the card convex also have sufficient strength to bear the pressure between the photovoltaic modules 200 and the external load.

[0087] The arrangement of the card slot and the card convex not only ensures a firm connection between the photovoltaic modules 200, but also facilitates installation and disassembly. Adjacent photovoltaic modules 200 are positioned and installed through the card slot and the card convex, making the installation of the photovoltaic modules 200 more convenient and greatly improving the installation efficiency. In addition, the corresponding engagement of the card slot and the card convex between adjacent photovoltaic modules 200 can further improve the waterproof effect, without the need for additional waterproof measures such as rubber strips and waterproof glue, which can further reduce costs.

[0088] In another embodiment, the upper mating surface 240 may be provided with a locking protrusion, and the lower mating surface 250 may be provided with a locking groove, which will not be described in detail here.

[0096] The second clip structure 270 on the second drain board 190 can be clipped and adapted to the photovoltaic assembly 200 near the second mounting rod 180, thereby achieving precise docking of the second drain board 190 with the corresponding photovoltaic assembly 200, thereby positioning the lower end of the photovoltaic assembly 200, and also ensuring a firm connection between the second drain board 190 and the photovoltaic assembly 200.

[0097] The first clamping structure 260 and the second clamping structure 270 can specifically be mechanisms such as a slot and an inserting portion, a clamping slot and a clamping protrusion, a clamping protrusion and a latch that cooperate with each other.

[0101] In one embodiment, one end of the first drain plate 170 away from the first mounting rod 160 is in an arc shape that is bent toward the second end 112 .

[0102] See also Figure 4 The end of the first drain plate 170 away from the first mounting rod 160 is in an arc shape bent toward the second end 112, which can further prevent rainwater from tilting from the rear side of the mounting bracket 100 to the bottom of the mounting bracket 100 and leaking onto the photovoltaic assembly 200.
