DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0040] In the embodiments of the present disclosure, words such as "first", "second", "third", and "fourth" are used to distinguish between identical or similar items with substantially the same functions and effects. This is only for the purpose of clearly describing the technical solutions of the embodiments of the present disclosure and shall not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0041] In the embodiments of the present disclosure, “plurality” means two or more than two, and “at least one” means one or more than one, unless otherwise clearly and specifically defined.

[0042] In the embodiments of the present disclosure, the orientation or positional relationship indicated by the terms "upper" and "lower" etc. is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure.

[0043] The embodiments of the present disclosure provide a photovoltaic power generation system, which may be a stand-alone photovoltaic power generation system (Stand-alone PV System) or a grid-connected photovoltaic power generation system (Grid-connected PV System).

[0044] The photovoltaic power generation system includes a photovoltaic module, which includes a laminated module having a light-receiving surface and a light-receiving surface that are arranged opposite to each other, and the light-receiving surface of the laminated module is used to receive solar radiation.

[0045] Exemplarily, the laminate assembly includes a backplane, an adhesive, a battery cell, and a glass cover plate stacked in sequence, the side of the backplane away from the battery cell can be the backlight side of the laminate assembly, and the side of the glass cover plate away from the battery cell is the light-receiving side of the laminate assembly. Of course, the embodiment of the present disclosure does not limit the structure of the laminate assembly.

[0046] The laminate assembly includes a long side and a short side, and the size of the long side is greater than the size of the short side. Exemplarily, the laminate assembly is rectangular as a whole, the long side of the laminate assembly refers to the length of the rectangle, and the short side of the laminate assembly refers to the width of the rectangle.

[0047] In actual application, a photovoltaic power generation system may include multiple photovoltaic modules, and the multiple photovoltaic modules constitute a photovoltaic module array.

[0048] The photovoltaic power generation system also includes a photovoltaic bracket, through which the photovoltaic assembly is fixed in an open area to facilitate the light-receiving surface of the laminated assembly to receive solar radiation. The open area can be land, water, or the top of a building or structure. For example, when the open area is land, the photovoltaic bracket can be fixed to the ground; when the open area is water, the photovoltaic bracket can be fixed to a pontoon; when the open area is the top of a building or structure, the photovoltaic bracket is fixed to the top of the building or structure.

[0049] In actual application, the photovoltaic power generation system may also include other components, which are not limited in the embodiments of the present disclosure. For example, when the photovoltaic power generation system is an independent photovoltaic power generation system, the photovoltaic power generation system also includes a battery pack, a charging controller, an inverter, etc., the solar radiation is converted into electrical energy by the photovoltaic components, and then the inverter is used to power the load, and the excess electrical energy is stored in the battery pack in the form of chemical energy after passing through the charging controller; when the photovoltaic power generation system is a grid-connected photovoltaic power generation system, the photovoltaic power generation system also includes a high-frequency DC boost circuit, an inverter, and a system monitoring device, etc., the solar radiation is converted into electrical energy by the photovoltaic components, and then converted into high-voltage DC by the high-frequency DC boost circuit, and then the inverter is inverted to output a sinusoidal AC current with the same frequency as the grid voltage to the grid.

[0050] Figure 1 FIG. 2 shows a side view of a photovoltaic module in the related art. Figure 1 As shown, in the related art, the backlight surface of the laminate assembly 1 is connected to a reinforcement 3 through a double-sided silicone strip 2, and the reinforcement 3 extends along the length direction of the photovoltaic assembly, thereby increasing the structural strength of the photovoltaic assembly. Among them, the reinforcement 3 is a high yield strength galvanized steel strip or stainless steel, which is formed by a stamping process and is in the shape of a "J" as a whole. The side wall of the reinforcement 3 away from the laminate 1 is provided with an opening, and a rivet nut 4 is riveted on the opening by a specific stamping die. When installing the photovoltaic assembly to the photovoltaic bracket, it is necessary to pass the bolt through the photovoltaic bracket and threadedly connect it with the rivet nut 4 on the reinforcement 3, which is time-consuming and labor-intensive.

[0051] In view of this, the embodiments of the present disclosure provide a reinforcing beam, a photovoltaic assembly and a photovoltaic power generation system, which can realize the rapid installation of the photovoltaic assembly and the photovoltaic bracket.

[0052] Figure 2 A partial structural diagram of a photovoltaic module is shown as an example. Figure 3 for Figure 2 A-direction view. Figure 2 and Figure 3 As shown, the laminate assembly 10 includes a light-receiving surface 10 a and a backlight surface 10 b that are disposed opposite to each other, and the reinforcing beam 20 is fixedly connected to the backlight surface 10 b of the laminate assembly 10 .

[0053] Exemplarily, the photovoltaic assembly includes a plurality of reinforcing beams 20, and the reinforcing beams 20 extend along the long side 11 of the laminate 10, and the plurality of reinforcing beams 20 are arranged at intervals along the short side 12 of the laminate assembly 10. The long side 11 of the laminate assembly 10 is the third direction Z, and the short side 12 of the laminate assembly 10 is the second direction Y.

[0054] The laminate assembly 10 has a relatively weak deformation resistance along the long side 11 , so the reinforcing beam 20 extending along the long side 11 of the laminate assembly 10 can improve the overall load resistance of the photovoltaic assembly, making the photovoltaic assembly less prone to deformation.

[0055] Among them, the number of reinforcing beams 20 can be two, three, four, etc. In actual application, the number of reinforcing beams 20 can be determined according to the size of the laminate 10 along the short side 12 and the distance between two adjacent reinforcing beams 20. The larger the size of the laminate assembly 10 along the short side 12, the greater the number of reinforcing beams 20. Figure 2 and Figure 3 In the description, the photovoltaic assembly including two reinforcing beams 20 is taken as an example for exemplary description.

[0056] Exemplarily, when the photovoltaic module includes two reinforcing beams 20, the spacing P between the two reinforcing beams 20 is 0.5-0.6 times the dimension of the laminate 10 along the short side 12, for example, the spacing P between the two reinforcing beams 20 is 0.5 times, 0.52 times, 0.55 times, 0.58 times or 0.6 times the dimension of the laminate 10 along the short side 12. The length L1 of the reinforcing beam 20 is 0.4-0.8 times the dimension of the laminate 10 along the long side 11, for example, the length L1 of the reinforcing beam 20 is 0.4 times, 0.5 times, 0.6 times, 0.7 times or 0.8 times the dimension of the laminate 10 along the long side 11.

[0057] Figure 4 The structure diagram of a purlin is shown as an example. Figure 5 Shows Figure 4 B-direction view. Figure 4 and Figure 5 As shown, the photovoltaic support further includes a purlin 30 , and the purlin 30 is used to connect the reinforcing beam 20 , so that the laminated assembly 10 is fixed on the photovoltaic support through the reinforcing beam 20 and the purlin 30 .

[0058] The purlin 30 may include a bottom wall 32 and two side walls 31 . The two side walls 31 are opposite to each other and spaced apart. The bottom wall 32 is connected between the two side walls 31 . The bottom wall 32 and the two side walls 31 enclose an accommodation space 30 a .

[0059] Exemplarily, the cross section of the purlin 30 is U-shaped. The open end of the U-shape is the opening of the accommodating space 30a of the purlin 30.

[0060] Of course, the cross section of the purlin 30 may also be in an I-shape, that is, the bottom wall 32 is connected to the middle position of the two side walls 31, so that the purlin 30 forms two accommodating spaces 30a, and each accommodating space 30a includes an opening.

[0061] The purlin 30 may be in the shape of a long strip. When the purlin 30 is connected to the reinforcing beam 20 , the extending direction of the purlin 30 is the same as the extending direction of the reinforcing beam 20 , and the opening of the accommodating space 30 a faces the backlight surface 10 b of the laminate assembly 10 .

[0062] Figure 6 An exemplary installation diagram of a photovoltaic module is shown. Figure 6 As shown, the photovoltaic power generation system may further include a clamp 40, and the reinforcing beam 20 is connected to the purlin 30 through the clamp 40. For example, the photovoltaic bracket of the photovoltaic power generation system may be a fixed bracket or a tracking bracket. When the photovoltaic bracket is a fixed bracket, the reinforcing beam 20 is connected to the purlin 30 through the clamp 40.

[0063] Fixed brackets are used to fix photovoltaic modules on the ground, roof or water surface in open areas at a fixed angle and position to fully receive solar radiation and achieve photovoltaic power generation. Tracking brackets are brackets that can automatically adjust the angle between photovoltaic modules and the ground according to the position of the sun and the lighting conditions. By tracking the movement of the sun, tracking brackets can maximize the energy output of photovoltaic modules.

[0064] Figure 7 The structure diagram of a card clip is shown as an example. Figure 7 As shown, the clamp 40 is provided with a clamping groove 42, and a stop hook 41 is provided in the clamping groove 42. Exemplarily, the notch of the clamping groove 42 is expanded to facilitate the installation with the reinforcing beam 20.

[0065] Figure 8 A cross-sectional view of a reinforcing beam is shown as an example. Figure 8 As shown, the reinforcing beam 20 includes a fixed wall 22 and a clamping wall 21. The clamping wall 21 has a first end and a second end opposite to each other. The first end is fixedly connected to the fixed wall 22, and the second end is suspended, so that the clamping wall 21 is a cantilever structure relative to the fixed wall 22. Figure 6 When the reinforcing beam 20 is connected to the clamp 40 , the second end of the clamping wall 21 is inserted into the clamping groove 42 along the first direction X.

[0066] The fixing wall 22 is used to be fixedly connected to the backlight surface of the laminate assembly 10. For example, the fixing wall 22 can be connected to the backlight surface 10b of the laminate assembly 10 by bonding. Exemplarily, the fixing wall 22 is bonded to the backlight surface 10b of the laminate assembly 10 by a double-sided silicone strip or a structural adhesive.

[0067] The side of the fixing wall 22 facing the laminate assembly 10 is a bonding surface, and the bonding surface is used to bond with the backlight surface 10b of the laminate assembly 10. In order to improve the bonding firmness, the bonding surface can be provided with a concave-convex structure. For example, the bonding surface is formed into a rough surface by stamping or sandblasting, thereby increasing the contact area between the bonding surface and the structural adhesive or double-sided silicone strip.

[0068] Continue to refer Figure 8 The clamping wall 21 is provided with a stop groove 20a. After the clamping wall 21 is inserted into the clamping groove 42 of the clamp 40, the stop hook 41 of the clamp 40 is clamped into the stop groove 20a to prevent the clamping wall 21 from coming out of the clamping groove 42. Specifically, after the stop hook 41 is clamped into the stop groove 20a, it is not easy to come out of the stop groove 20a, so that the clamping wall 21 is not easy to come out of the clamping groove 42. The clamp 40 is connected to the reinforcing beam 20 by the cooperation of the stop hook 41 and the stop groove 20a, which has a simple structure and improves assembly efficiency.

[0069] Continue to refer Figure 7 and Figure 8 The reinforcing beam 20 may further include a connecting wall 23, which is connected between the fixed wall 22 and the clamping wall 21. The clip 40 includes a butting area 43, which is located at the periphery of the notch of the clamping groove 42. After the clamping wall 21 is inserted into the clamping groove 42, the butting area 43 butts against the connecting wall 23, thereby preventing the reinforcing beam 20 from rotating relative to the clamp 40, so that the connection between the reinforcing beam 20 and the clamp 40 is more secure.

[0070] The clamping wall 21, the connecting wall 23 and the fixing wall 22 can be bent sheet metal of an integral structure. The bent sheet metal of an integral structure here refers to a sheet metal structure formed by bending or stamping a whole sheet metal piece for multiple times, which is different from an integral structure connected by welding, riveting, bolting, etc.

[0071] The clamping wall 21 , the connecting wall 23 and the fixing wall 22 may be a single-layer sheet metal structure or a multi-layer sheet metal structure (eg, double-layer, triple-layer, etc.). The more sheet metal layers there are, the higher the strength and rigidity of the reinforcing beam 20 . Figure 8 Shown in FIG is a double-layer sheet metal structure.

[0072] The fixed wall 22 may include a first fixed wall 221 and a second fixed wall 222 which are stacked. The first fixed wall 221 and the first connecting wall 231 are an integral structure, and the second fixed wall 222 and the second connecting wall 232 are an integral structure.

[0073] When the reinforcing beam 20 is a double-layer structure of a bent sheet metal, the two ends of the bent sheet metal can be located at the second end of the fixed wall 22 or the clamping wall 21. The two ends of the bent sheet metal refer to the two ends of the sheet metal part that are opposite to each other along the direction perpendicular to the fold. After the bending is completed, the two ends of the bent sheet metal can be aligned or adjacent ( Figure 8 20b shows the situation where both ends of the bent sheet metal are aligned).

[0074] The fixed wall 22 is fixedly connected to the backlight surface of the laminate assembly 10, and the backlight surface of the laminate assembly 10 is relatively flat, so the connection between the fixed wall 22 and the connecting wall 23 is easily subjected to bending force, while the inside of the fixed wall 22 is not easily subjected to bending force. In view of this, the two ends of the bent sheet metal can be located at the fixed wall 22, so that the two ends of the bent sheet metal and the structural rigidity of the reinforcing beam 20 are less affected.

[0075] Exemplarily, the two ends of the bent sheet metal are located on the bonding surface. In this way, the two ends of the bent sheet metal are respectively bonded to the laminate assembly 10, so that the two ends of the bent sheet metal are respectively fixed relative to the laminate assembly 10, and relative displacement between the two ends of the bent sheet metal is not easy to occur. In addition, due to the existence of process errors, the two ends of the bent sheet metal may have a step difference along the second direction, and the existence of the step difference can increase the contact area between the bonding surface and the structural adhesive, thereby improving the bonding firmness.

[0076] In actual application, the two ends of the bent sheet metal are in contact along the first direction to prevent the structural adhesive from entering the interior of the fixed wall 22 along the seam between the two ends of the bent sheet metal.

[0077] The second end of the clamping wall 21 is used to be inserted into the clamping groove 42 , so the second end of the clamping wall 21 is not easily subjected to bending force, and the requirement for structural rigidity is relatively low. Fig. 9 The structure diagram of a reinforcing beam 20 is shown as an example. Fig. 9 As shown, the two ends of the bent sheet metal can also be arranged at the second end of the clamping wall 21.

[0078] Exemplarily, one or both ends of the bent sheet metal can be bent to form a guide structure, and when the engaging wall 21 is inserted into the inserting groove, the retaining hook 41 is inserted into the retaining groove 20a under the guidance of the guide structure.

[0079] Since the clamping wall 21 is a cantilever structure as a whole, in order to improve the structural rigidity of the clamping wall 21 and prevent the clamping wall 21 from bending and deforming. Figure 8 and Fig. 9 The clamping wall 21 includes a first clamping wall 211 and a second clamping wall 212, and the second clamping wall 212 covers the side of the first clamping wall 211 facing the stop hook 41. The second clamping wall 212 covers the surface of the first clamping wall 211, so that the clamping wall 21 has a double-layer structure, which improves the structural rigidity of the clamping wall 21 and prevents the clamping wall 21 from being deformed. In addition, the thickness of the clamping wall 21 along the second direction Y increases, so that the clamping wall 21 and the clamping groove 42 are more closely matched, preventing the clamping wall 21 from shaking in the clamping groove 42.

[0080] Continue to refer Figure 8 and Fig. 9 In some embodiments, the second clamping wall 212 includes a supporting area 212a, and a gap is provided between the supporting area 212a and the first clamping wall 211, so that the thickness of the clamping wall 21 along the second direction Y is increased, so that the clamping wall 21 and the clamping groove 42 fit more closely, preventing the clamping wall 21 from shaking in the clamping groove 42.

[0081] For example, along the first direction, the areas on both sides of the support area 212a are in direct contact with the first clamping wall 211, so that the support area 212a is in a bridge-shaped structure as a whole. In actual application, the distance between the support area 212a and the first clamping wall 211 can be slightly larger than the size of the clamping groove 42 along the second direction. When the clamping wall 21 is inserted into the clamping groove 42, the support area 212a is elastically deformed under the extrusion of the clamping groove 42, so that the connection between the clamping wall 21 and the clamping groove 42 is more firmly established.

[0082] After the clamping wall 21 is inserted into the clamping groove 42, the stop hook 41 cooperates with the stop groove 20a. When the clamping wall 21 shakes in the clamping groove 42, the clamping wall 21 usually rotates around the stop groove 20a. Therefore, the closer the area is to the first end, the greater the shaking amplitude. Figure 8 and Fig. 9 The supporting area 212 a is closer to the first end relative to the clamping groove 42 to reduce the shaking amplitude of the clamping wall 21 or eliminate the shaking of the clamping wall 21 .

[0083] The following describes the situation where both ends of the bent sheet metal are located at the fixed wall 22 and the situation where both ends of the bent sheet metal are located at the second end of the clamping wall 21 in conjunction with the drawings.

[0084] First, the situation where both ends of the bent sheet metal are located on the fixed wall 22 is introduced.

[0085] Continue to refer Figure 8 The second clamping wall 212 further includes a recessed area 212b, which is recessed toward the first clamping wall 211 to form a stop groove 20a. At this time, the areas on both sides of the stop groove 20a are smoothly transitioned, and the stop hook 41 is easier to escape from the stop groove 20a, which facilitates the disassembly of the clamping wall 21 and the clamping groove 42.

[0086] The recessed area 212b may extend along the length direction (third direction Z) of the reinforcing beam 20. For example, the recessed area 212b may extend from one end of the reinforcing beam 20 to the other end of the reinforcing beam 20 along the third direction Z. In this way, the size of the anti-retraction groove 20a along the length direction of the reinforcing beam 20 may be increased, thereby increasing the matching area between the anti-retraction hook 41 and the anti-retraction groove 20a, and making the connection between the reinforcing beam 20 and the clamp 40 more secure.

[0087] Exemplarily, along the first direction, gaps are provided between the areas on both sides of the recessed area 212b and the first clamping wall 211. Further, the supporting area 212a is connected to the recessed area 212b.

[0088] Continue to refer Figure 8 The connecting wall 23 includes a first connecting wall 231 and a second connecting wall 232. The second connecting wall 232 is located on the side of the first connecting wall 231 facing the clamping wall 21. The first connecting wall 231 and the first clamping wall are an integral structure, and the second connecting wall 232 and the second clamping wall 212 are an integral structure. The overall structural rigidity of the connecting wall 23 is improved, and the connecting wall 23 is not easily deformed.

[0089] Among them, Figure 8 As shown, the first connecting wall 231 and the second connecting wall 232 can be stacked, which improves the structural rigidity of the connecting wall 23 and reduces the volume of the reinforcing beam 20.

[0090] Fig.10 The cross-sectional structure diagram of a reinforcing beam 20 is shown as an example. Fig.11 The cross-sectional structure diagram of a reinforcing beam 20 is shown as an example. Fig.10 and Fig.11 As shown, a gap is provided between the second connecting wall 232 and the first connecting wall 231, so that the reinforcing beam 20 is in a hollow tubular shape, that is, the cross section of the reinforcing beam 20 is a closed figure, thereby improving the load-bearing capacity of the reinforcing beam 20.

[0091] For example, Fig.10 As shown, the fixed wall 22, the first connecting wall 231, the second connecting wall 232 and the first clamping wall 211 form a hollow tube. The embodiment of the present disclosure does not limit the shape of the cross section of the hollow tube. For example, the cross section of the hollow tube can be a rectangle (such as Fig.10 ), squares, triangles and other polygons, circles, ellipses and other irregular shapes (such as Fig.11 shown) etc.

[0092] Exemplarily, when the cross-section of the hollow tube is a rectangle, the short side of the rectangle is 10mm-100mm, for example, 10mm, 20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc., and the long side of the rectangle is 5mm-30mm, for example, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc., and there is a rounded transition between two adjacent side walls of the reinforcing beam 2020, the outer diameter of the rounded corner is 0.5mm-3.5mm, and the side wall thickness of the reinforcing beam 2020 is 0.3mm-3mm.

[0093] The reinforcing beam 20 may be made of steel with a thickness of 0.3 mm to 3.0 mm, such as 0.3 mm, 0.6 mm, 0.9 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, etc.

[0094] Continue to refer Fig.11 In some embodiments, a portion of the second connecting wall 232 is recessed toward the first connecting wall 231 to form a receiving groove 20b, and the abutting area 43 is located in the receiving groove 20b, so that the relative rotation between the reinforcing beam 20 and the clamp 40 is limited by the receiving groove 20b.

[0095] Exemplarily, the depth A4 of the receiving groove 20b is twice the thickness of the sheet metal.

[0096] Exemplarily, the upper surface of the clip 40 is in contact with the side wall of the receiving groove 20 b close to the fixed wall 22 .

Fig.12 As shown, a partial area of ​​the second connecting wall 232 is recessed toward the first connecting wall 231 and fits with the first connecting wall 231, and a gap is provided between the remaining area of ​​the second connecting wall 232 and the first connecting wall 231, so that the depth of the accommodating groove 20b is deeper, thereby limiting the relative rotation between the reinforcing beam 20 and the clamp 40.

Fig.13 As shown, the first clamping wall 211 may also include a reinforcement area 211a, which is located between the first connecting wall 231 and the second connecting wall 232. The reinforcement area 211a is recessed toward the fixed wall 22, and a portion of the structure of the reinforcement area 211a covers the connection between the second connecting wall 232 and the second clamping wall 212, thereby increasing the rigidity of the connection between the clamping wall 21 and the connecting wall 23 and preventing the connection between the clamping wall 21 and the connecting wall 23 from bending and deformation.

[0099] Exemplarily, the radius R1 is 2 mm-3 mm, for example, 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm.

After the end of the first clamping wall 211 is clamped with the stop hook 41, it is more difficult to disengage, so that the connection between the reinforcing beam 20 and the clamp 40 is more secure. In addition, the end of the first clamping wall 211 covers the end of the second clamping wall 212 to form a three-layer sheet metal structure, and the second end of the clamping wall 21 has stronger rigidity.

[0103] Exemplarily, a dimension A3 of a region of the first clamping wall 211 that is covered by the second clamping wall 212 along the first direction is greater than twice the thickness of the sheet metal.
