Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of photovoltaic integration, and in particular to an assembled photovoltaic integration module and a photovoltaic system. Background Art
[0002] Steel structures are primarily used in industrial plants, stadiums, and transportation facilities such as airports and high-speed rail. They are typically single-story buildings with large footprints, wide spans, and large individual building areas. However, new construction, expansions, and renovations, as well as energy-saving retrofits of existing buildings, require energy-efficient design, which means installing photovoltaic power generation systems on the roofs of steel structures. However, adding a photovoltaic system to the roof requires an increase in the dead load, which in turn increases the overall steel usage of the steel structure, contradicting the need for building energy efficiency. Therefore, it is necessary to ensure that the roof can support the photovoltaic modules without requiring additional roof modifications.
[0003] Currently, photovoltaic modules are generally first fixed to the crests of the color steel tiles on the roof using metal clamps through bolts, metal purlins are fixed to the metal clamps, and then the photovoltaic modules are fixed and locked using metal pressure blocks and bolts to achieve the fixation of the photovoltaic modules on the color steel tiles. However, with this installation method, the fixed connection between the metal clamps and the crests of the roof color steel tiles is easily deformed by wind. In addition, the metal clamps and the crests of the color steel tiles will produce a friction effect, resulting in damage to the waterproof and anti-corrosion coatings of the crests of the color steel tiles. However, the service life of ordinary color steel tile roofs does not match that of photovoltaic modules. How to extend the service life of the color steel tile roofs of existing steel structure buildings, reduce the risk of replacing tiles and disassembling photovoltaic modules, and ensure their coexistence.
[0004] Furthermore, such photovoltaic panels have poor compressive strength and are easily broken by external forces such as hail. During the assembly of photovoltaic panels, workers inevitably have to walk on them. To improve efficiency, existing technologies also employ modular photovoltaic module designs and use automated assembly equipment to walk on them to install and assemble the panels.
[0005] Existing photovoltaic / solar thermal (PV / T) technology is an integrated product, combining photovoltaic power generation technology and a solar collector. Primarily composed of photovoltaic modules and heat exchangers, it can generate both electricity and heat. Because the efficiency of PV panels decreases as the cell temperature rises, circulating fluid through the solar collector cools the panels, minimizing power generation losses, improving solar energy utilization, and better meeting building energy efficiency requirements. However, integrating these two technologies increases costs and limits their application scenarios. Therefore, a split, composite system product design is needed to achieve a balance between cost reduction and energy conservation, meet the needs of a wider range of applications, and reduce the difficulty of market promotion and technology popularization. Summary of the Invention
[0006] Based on this, the purpose of the present invention is to provide an assembled photovoltaic integrated module and photovoltaic system, aiming to solve the problem in the prior art of the lack of an assembled photovoltaic integrated module product with light weight, strong pressure resistance, good waterproof performance, support plate and photovoltaic component with the same service life, high solar energy utilization rate and high assembly efficiency, to realize factory industrial prefabrication production and manufacturing, and reduce the problem of difficult quality control of on-site assembly and gluing.
[0007] According to an embodiment of the present invention, an assembled photovoltaic integrated module includes a photovoltaic component, a support plate arranged at the bottom of the photovoltaic component, a support connecting sleeve and a support seat arranged below the support plate, the support seat is used to connect with the roof color tile steel purlin, the support plate is in a five-shaped wavy shape, the support connecting sleeve is arranged at the bottom of the wave crest of the support plate, and is located between the support plate and the support seat for auxiliary support, the middle part of the wave crest of the support plate is recessed downward to form a glue groove, so that the photovoltaic component and the support plate are fixedly connected by glue.
[0008] The present invention provides a wavy support plate for supporting photovoltaic modules, and adjusts the distance between adjacent wave peaks so that the distance between adjacent wave peaks is less than the width of a construction worker's foot or less than the width of the wheels of the construction equipment, so as to ensure that the support plate provides sufficient support force to improve the compressive strength of the photovoltaic panel and prevent the photovoltaic panel from breaking. In addition, by providing a glue groove, the photovoltaic module is connected to the support plate, and a support connecting sleeve connected to the support plate is provided, and adjacent photovoltaic modules are connected to each other through the support connecting sleeve. This connection and fixing method avoids the friction and tearing effect of the clamp on the roof and the photovoltaic panel, thereby improving the service life of the photovoltaic module. In addition, the bent wave-shaped support plate used to support the photovoltaic module and connect to the roof is lighter than a horizontal whole panel or a panel that requires additional clamps for fixing. Semi-flexible crystalline silicon lightweight photovoltaic modules can be used to further reduce the weight of the photovoltaic module. In addition, by rationally adjusting the position of the supporting connection sleeve, the connecting support sleeve and the support plate cooperate with each other, thereby strengthening the mechanical structural strength of the longitudinal spacing, reducing the deformation of the photovoltaic integrated modular product when subjected to trampling pressure and hail impact pressure, and preventing the hidden cracks of the photovoltaic module crystalline silicon cell. In addition, through the socket-type connection of the supporting connection sleeve and sufficient pressure resistance, automatic assembly equipment can be used to improve the assembly efficiency. Therefore, the present invention solves the problem in the prior art of the lack of an assembled photovoltaic integrated module product with light weight, strong pressure resistance, good waterproof performance, support plate and photovoltaic module with the same service life, high solar energy utilization rate and high assembly efficiency.

[0038]
[0039] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION
[0040] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.
[0041] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0043] See also Figures 1 to 8 , which shows an assembled photovoltaic integrated module in one embodiment of the present invention, including a photovoltaic module 10, a support plate 20 disposed at the bottom of the photovoltaic module 10, a support connection sleeve 30 and a support base 40 disposed below the support plate 20, wherein:
[0044] The support seat 40 is used to connect with the roof colored tile steel purlins. The support plate 20 is in a five-shaped wavy shape. The support plate 20 connecting sleeve is set at the bottom of the crest of the support plate 20, and is located between the support plate 20 and the support seat 40 for auxiliary support. The middle part of the crest of the support plate 20 is concave downward to form a glue groove 21, so that the photovoltaic module 10 and the support plate 20 are fixedly connected by glue, and the drying equipment is used to accelerate the curing.
[0045] It is understandable that by providing a wavy support plate 20 for supporting the photovoltaic module 10, the support plate can be made of a metal corrugated plate or other non-metallic composite material, and the distance between adjacent wave peaks is adjusted so that the distance between adjacent wave peaks is less than the width of the construction worker's foot or less than the width of the construction equipment's driving wheel, so as to ensure that the support plate 20 provides sufficient support force to improve the compressive strength of the photovoltaic panel and prevent the photovoltaic panel from breaking. In addition, by providing a glue groove 21, the photovoltaic module 10 is connected to the support plate 20, and a support connection sleeve 30 connected to the support plate 20 is provided, and adjacent photovoltaic modules are connected to each other through the support connection sleeve 30. This connection and fixing method avoids the friction and tearing effect of the clamp on the roof and the photovoltaic panel, thereby improving the service life of the photovoltaic module 10. In addition, the bent wave-shaped support plate 20 is used to support the photovoltaic module 10 and is used to connect to the roof. Compared with a horizontal whole panel and the need for additional clamps to fix it, it is lighter. Semi-flexible crystalline silicon lightweight photovoltaic modules can be used to further reduce the weight of the photovoltaic module. In addition, by rationally adjusting the position of the support connecting sleeve 30, the connecting support sleeve and the support plate 20 cooperate with each other, thereby strengthening the mechanical structural strength of the longitudinal spacing, reducing the deformation of the photovoltaic integrated modular product when subjected to trampling pressure and hail impact pressure, and preventing hidden cracks in the crystalline silicon cells of the photovoltaic module 10. In addition, the socket-type connection of the support connecting sleeve 30 and sufficient pressure resistance allow the use of automatic assembly equipment, thereby improving assembly efficiency. Therefore, the present invention solves the problem in the prior art of the lack of an assembled photovoltaic integrated module that is lightweight, has strong pressure resistance, high service life, and high assembly efficiency.
[0046] It should be noted that the existing building photovoltaic integration technology solution using structural adhesive to glue photovoltaic modules 10 is to first press color steel tiles at the project construction site using a high-altitude tile press, and then fix the photovoltaic modules 10 on the color steel tiles with structural adhesive. The gluing process is greatly affected by external environmental factors (temperature, humidity). It generally takes 24-72 hours for the structural adhesive to dry and cure to reach the standard bonding strength, and there is a curing and curing time of 14-21 days. Under low temperature and low humidity, the curing speed of the structural adhesive will be slower, and the curing period after gluing will be longer in winter. In order to ensure the bonding performance, it is even necessary to place heavy objects on the photovoltaic modules 10. During this period, the photovoltaic modules 10 are prone to displacement, loosening and false adhesion, and the construction quality is difficult to control. In the photovoltaic integrated module of the present application, the support plate 20, the photovoltaic assembly 10 and the support connecting sleeve 30 are all assembled and connected, and then transported to the construction unit as independent individual parts for construction. That is, the step of fixing the photovoltaic assembly 10, the support connecting sleeve 30 and the support plate 20 with structural adhesive has been completed in the dust-free workshop of the factory. Therefore, the present application eliminates the problems existing in the on-site construction of the above-mentioned structural adhesive.
[0047] In addition, an auxiliary tube 50 is provided at one end of the support and connection sleeve 30. The outer contour of the auxiliary tube 50 is smaller than the inner contour of the support and connection sleeve 30. Slots 51 are provided on both sides of the auxiliary tube 50. A through slot 31 is provided at the other end of the support and connection sleeve 30 to match the slot 51. A block 32 is provided in the through slot 31, which is inclined toward the inner side of the support and connection sleeve 30. The block 32 cooperates with the slot 51 to connect adjacent prefabricated photovoltaic integrated modules in the length direction of the support and connection sleeve 30. In a specific implementation, the support and connection sleeve 30 is connected to the support plate 20 by welding, gluing, or mechanical metal fitting. The support and connection sleeve 30 can be formed of metal or non-metallic materials. By providing the auxiliary tube 50, the slot 51, and the block 32, adjacent prefabricated photovoltaic integrated modules can be quickly assembled and connected by fitting the end of the support and connection sleeve 30 without the auxiliary tube 50 onto the auxiliary tube 50 and inserting the block 32 into the slot 51. In addition, glue grooves 21 can be provided on both sides of the slot 51 of the auxiliary tube 50, so that the two supporting connecting sleeves 30 are not only connected by the mortise and tenon joints, but also reinforced and fixed by structural glue to enhance the connection strength. In addition, the length of the supporting connecting sleeve 30 is equal to the spacing between the two roof purlins and the truss support system. It is installed on the roof purlin or truss support system. The combination of the supporting connecting sleeve 30 and the supporting corrugated metal plate strengthens the mechanical structural strength of the longitudinal spacing, reduces the deformation of the photovoltaic integrated modular product when subjected to trampling pressure and hail impact pressure, and prevents the hidden cracking of the photovoltaic module 10 crystalline silicon cell. The number of supporting connecting sleeves 30 installed at the bottom of the supporting corrugated metal plate crest can be increased or decreased according to the actual needs of structural strength. By installing the supporting connecting sleeve 30 at the bottom of the supporting corrugated metal plate crest, the material optimization of the thickness of the supporting corrugated metal plate and the thickness of the supporting connecting sleeve 30 is achieved, thereby reducing the amount of steel or non-metallic supporting plate materials used, achieving the purpose of energy saving and consumption reduction in buildings.
[0048] Specifically, the plurality of support and connection sleeves 30 are evenly distributed at the bottom of the crest of the support plate 20. The sizes of the support and connection sleeves 30 are consistent, and the lengths of the support and connection sleeves 30 extending from one side of the photovoltaic module 10 are inconsistent. By way of example and not limitation, in some optional embodiments, the sizes of the support and connection sleeves 30 are consistent, and the lengths of adjacent support and connection sleeves 30 extending from the photovoltaic module 10 are different, so that the contact points between adjacent support and connection sleeves 30 and the auxiliary tube 50 are not in the same plane, thereby preventing stress concentration and enhancing the overall compression, tension, and shear resistance of the device.
[0049] For example and non-limiting examples, see Figures 10 to 12 as well as Figure 15 and Figure 16As shown, in some optional embodiments, a first clip 24 and a second clip 25 are provided at both ends of the support plate 20, respectively, which are adapted to each other. The first clip 24 includes a cylindrical portion 241 provided on the support plate 20 and a flange portion 242 provided on the top of the cylindrical portion 241. The second clip 25 includes a fixed flange 251 provided on the support plate 20 and a spring clip 252 provided within the fixed flange 251. The spring clip 252 is adapted to the cylindrical portion 241 and is fixed by rivets 26 to securely connect the support plates 20 on both sides. In addition, the tightness of the connection between the support plates 20 is further enhanced, so that the integrity of the multiple assembled photovoltaic integrated modules is high. When subjected to a large range of forces, the multiple assembled photovoltaic integrated modules can quickly and evenly distribute the forces as a whole, thereby enhancing wind resistance and preventing localized force concentration damage. In addition, a snap 27 is provided on the cylindrical portion 241 to enhance the tightness of the connection between the spring clip 252 and the flange portion 242, thereby further strengthening the connection strength between adjacent support plates 20. Furthermore, in a specific implementation, the cylindrical portion 241, flange portion 242, and fixed flange 251 can be formed by punching and turning a portion of the support plate 20, and then the first and second clips 24, 25 are formed using the existing spring clip 252, snap 27, and rivet 26. This reduces the difficulty of manufacturing the first and second clips 24, 25. Furthermore, compared to simply providing two connecting holes connected by rivets 26, the additional flange portion 242, fixed flange 251, snap 27, and spring clip 252 locally strengthen the clip connection, thereby preventing localized force concentration at the clip connection, which could lead to deformation and damage. After adopting this connection method, the connection between photovoltaic modules 10 is more tightly connected and the spacing is smaller. Furthermore, by installing a stepped waterproof plate 28 below each side of the photovoltaic module 10, after the two support plates 20 are overlapped and locked together, the two waterproof plates 28 will also overlap each other. This allows the waterproof plate 28 to replace the breathable waterproof component 80, further reducing the overall weight and cost of the photovoltaic module. In addition, when adopting this connection method, the rivets 26 can be used to directly connect to the roof tile steel purlins, thereby eliminating the need for the support base 40, further reducing the overall weight of the photovoltaic module, and reducing the additional load and cost of the building.
[0050] In addition, the support plate 20 is provided with a first connector 22 and a second connector 23 that cooperate with each other on both sides. The first connector 22 includes a first horizontal portion 221, a first L-shaped portion 222 perpendicularly connected to one end of the first horizontal portion 221, and a vertical portion 223 perpendicularly connected to the other end of the first L-shaped portion 222. The second connector 23 includes a second horizontal portion 231, a second L-shaped portion 232 perpendicularly connected to the other end of the second horizontal portion 231, and a third L-shaped portion 233 perpendicularly connected to the other end of the second L-shaped portion 232. The second connector 23 is sleeved on the first connector 22 so that the second L-shaped portion 232 and the third L-shaped portion 233 are respectively abutted against the first L-shaped portion 222 and the vertical portion 223. In a specific implementation, the second connector 23 is sleeved on the first connector 22 so that two adjacent assembled photovoltaic integrated modules can be quickly assembled and connected, and the first connector 22 and the second connector 23 interact with each other to at least limit the movement of the assembled photovoltaic integrated module in the left and right directions. In addition, by way of example and not limitation, in some optional embodiments, the transverse section of the third L-shaped portion 233 can be bent toward the vertical portion 223, thereby enabling interaction between the first connector 22 and the second connector 23. This can also limit the movement in the up and down directions between the assembled photovoltaic integrated modules, thereby retaining only the degrees of freedom in the front and back directions for assembly, further improving the connection strength between the assembled photovoltaic integrated modules, and making the multiple assembled photovoltaic integrated modules highly integrated. When subjected to a larger range of forces, such as a large area of wind of a certain intensity, the multiple assembled photovoltaic integrated modules can quickly and evenly share the forces as a whole, thereby enhancing wind resistance and preventing localized concentrated force damage.
[0051] It should be noted that, by way of example and not limitation, in some optional embodiments, the support plate 20 is formed by integrally pressing a metal plate. The size of the metal plate is usually fixed, and after the metal plate is pressed into a wavy shape, the width of the metal plate becomes smaller, that is, the size becomes smaller. To ensure that the size of the metal plate after pressing is as large as possible and to reduce the number of metal plates required, the number of wave peaks is usually as small as possible, that is, the spacing between the wave peaks is as large as possible while ensuring the requirements. This may result in the structural strength after pressing not meeting the requirements. If the spacing between the wave peaks is reduced and the spacing is not adjusted properly, the size of the two sides of the corrugated metal plate will not be suitable for forming another wave peak. Therefore, by providing a support connecting sleeve 30, multiple support connecting sleeves 30 are used to assist in adjusting the overall structural strength of the support plate 20. The support connecting sleeve 30 can also be formed by integrally pressing a metal plate and has adjustable size. By adjusting the position and number of the support connecting sleeve 30, the structural strength of the metal plate and the support connecting sleeve 30 as a whole can be adjusted, and metal plates of different thicknesses can be used. In addition, the first connecting member 22 and the second connecting member 23 are also integrally formed with the support plate 20 and are all formed by pressing a metal plate. Since the first connecting member 22, the second connecting member 23 and the support plate 20 are arranged as one piece, the structural strength between the first connecting member 22, the second connecting member 23 and the support plate 20 is further ensured.
[0052] Specifically, the first horizontal portion 221 and the second horizontal portion 231 form the trough of the support plate 20. The length of the first horizontal portion 221 is greater than the second horizontal portion 231, so that the position where the first connector 22 and the second connector 23 are fixed together is offset from the midpoint of the trough. Since the first connector 22, the second connector 23, and the support plate 20 are pressed and formed from the same metal sheet, and the second connector 23 is mounted on the first connector 22, the length of the first horizontal portion 221 needs to be greater than the second horizontal portion 231 to ensure that there is sufficient metal sheet size to form a second L-shaped portion 232 that is larger than the first L-shaped portion 222, so that the second L-shaped portion 232 can be mounted on the first L-shaped portion 222. The combination of the first L-shaped portion 222 and the second L-shaped portion 232 forms a space for accommodating the DC cable connecting the photovoltaic module electrical series. In addition, in a specific implementation, the support plate 20 is fixedly connected to the support base 40 via rivets. The rivet is set in the center of the trough of the support plate 20, and the position where the first connecting member 22 and the second connecting member 23 are attached and fixed is offset from the midpoint of the trough, which can avoid stress concentration and enhance the overall structural strength.
[0053] In addition, a heat dissipation pipe 60 is provided between the photovoltaic assembly 10 and the support base 40, which is provided between the peaks or troughs of the support plate 20. A heat exchange medium is provided in the heat dissipation pipe 60 and is connected to an external driving device, and the heat exchange medium is driven to flow in the heat dissipation pipe 60 by the driving device. By providing the heat dissipation pipe 60, the heat in the photovoltaic assembly 10 is quickly lost, thereby improving the power generation efficiency of the photovoltaic assembly 10. In addition, the heat exchange medium can be water, and the driving member can be a water pump, which drives the unheated water into the heat dissipation pipe 60 continuously by the water pump, and flows out after being heated in the heat dissipation pipe 60, and is introduced into the lithium bromide refrigeration unit to achieve preheating of the water, improve the utilization efficiency of solar energy, better achieve building energy conservation, and reduce the power generation loss caused by the excessive temperature of the photovoltaic power generation system. In addition, the heat exchange medium can also be air, and the cold air is introduced into the heat dissipation pipe 60 by a fan, and in winter, the air heated by the heat dissipation pipe 60 can be passed into the building interior, improving the indoor comfort, reducing the energy consumption of air conditioning, achieving building energy conservation, and killing two birds with one stone.
[0054] Specifically, the support sleeve 30 and the support plate 20 are provided with avoidance grooves on their sides, allowing the heat dissipation pipes 60 to be distributed in a serpentine shape beneath the photovoltaic module 10. Since the support plate 20 and photovoltaic module 10 are fixedly connected by structural adhesive, and there are differences in the thermal expansion coefficients between the structural adhesive, the support plate 20, and the photovoltaic module 10, to prevent local overheating that could cause the structural adhesive area to detach or deform, the heat dissipation pipes 60 need to be distributed in a serpentine shape to evenly dissipate heat throughout the module, reduce local temperature differences, and avoid deformation caused by excessive local temperature differences.
[0055] In addition, see Figures 13 and 14 as well as Figure 17 and Figure 18As shown, the support and connection sleeve 30 is filled with a phase change material 90. The phase change material 90 is a modified composite phase change material with organic paraffin, inorganic hydrated salt sodium sulfate decahydrate, calcium chloride hexahydrate, or a eutectic mixture and a porous material such as diatomaceous earth, calcium carbide, or renewable plastic foam as a carrier, or a modified composite phase change material doped with a thermally conductive material. By providing the phase change material 90 to assist in heat absorption, the heat dissipation effect of the device is further improved, thereby avoiding local overheating that causes the structural adhesive area to fall off or deform. In addition, due to the filling of the phase change material 90, the support strength of the support and connection sleeve 30 is increased, and the thickness of the support and connection sleeve 30 can be appropriately thinned to reduce the overall weight of the photovoltaic module. In addition, in a specific implementation, the space outside the support and connection sleeve 30 can also be filled with the phase change material 90, or the support and connection sleeve 30 is not provided and only the phase change material 90 is filled. In addition, a nozzle 62 may be provided on the heat dissipation pipe 60. Specifically, a connecting pipe 61 may be provided locally on the heat dissipation pipe 60, and multiple nozzles 62 may be provided on the connecting pipe 61. This allows the nozzles 62 to spray water in the form of mist when water is used as the heat exchange medium, thereby further improving the heat dissipation effect. Furthermore, in a specific implementation, waterproof grooves 29 are provided at both ends of the support plate 20 near the heat dissipation pipe 60. Waterproof rubber strips may be provided within the waterproof grooves 29. The additional provision of the waterproof grooves 29 and the waterproof rubber strips prevents water from the nozzles 62 and the heat dissipation pipe 60 from entering the photovoltaic module 10.
[0056] In addition, a waterproof cover plate 70 is provided above the first connector 22 and the second connector 23, and a breathable waterproof component 80 is provided above the connection between the two supporting connecting sleeves 30. The tops of the waterproof cover plate 70 and the breathable waterproof component 80 are flush. The breathable waterproof component 80 can be a breathable waterproof film sandwiched between two metal parts. The breathable waterproof film allows cool air to enter to assist in heat dissipation while preventing rainwater from entering, achieving a waterproof function. The waterproof cover plate 70 is provided so that the waterproof cover plate 70, the breathable waterproof component 80, and the top of the photovoltaic module 10 are flush with each other to form a horizontal surface, forming a first layer of physical waterproof structure. After the corrugated metal sheets of the product are overlapped and spliced, a second layer of physical waterproof structure is formed.
[0057] Specifically, the waterproof cover plate 70 includes a first transverse plate portion 71, vertical plate portions 72 symmetrically arranged on both sides of the first transverse plate portion 71, an inclined plate portion 73 extending inwardly and tilted from the vertical plate portions 72, and a second transverse plate portion 74 connected to the inclined plate portion 73. The two vertical plate portions 72 abut against the sides of the photovoltaic module 10, the inclined plate portion 73 on one side abuts against the hypotenuse on the support plate 20, and the second transverse plate portion 74 on the other side abuts against the second L-shaped portion 232. By the vertical plate portions 72 abutting against the photovoltaic module 10, the waterproof cover plate 70 can be moved left and right. By the inclined plate portion 73 on one side abutting against the hypotenuse on the support plate 20, and the second transverse plate portion 74 on the other side abutting against the second L-shaped portion 232, the waterproof cover plate 70 is restricted from further downward movement after it descends to a certain height under the action of gravity, thereby achieving rapid positioning of the waterproof cover plate 70 and improving the assembly efficiency of the assembled photovoltaic integrated module.
[0058] Also, see Figure 6 and Figure 9 As shown, for purposes of example and not limitation, in some optional embodiments, a metal sheet can be spot-welded between two troughs on the back of the support plate 20. This metal sheet secures the heat dissipation pipe and strengthens the connection strength on the back of the support plate 20, thereby reducing the deformation amplitude of the support plate 20 under stress on the front side and allowing a smoother assembly between the components on the back side and the support plate 20. Furthermore, the support plate 20 is constructed by bending a single piece. When subjected to a compressive force from the front side, it easily unfolds flatly to both sides like origami. Therefore, by providing a metal sheet at the bottom of the wave crest on the back side of the support plate 20 to connect the two troughs, the strength of the trough structure is strengthened to prevent deformation under compressive stress.
[0059] In summary, the present invention provides a wavy support plate 20 for supporting the photovoltaic module 10, and adjusts the distance between adjacent wave peaks so that the distance between adjacent wave peaks is less than the width of the construction worker's foot or less than the width of the construction equipment's driving wheel, so as to ensure that the support plate 20 provides sufficient support force to improve the compressive strength of the photovoltaic panel and avoid the photovoltaic panel from breaking. In addition, by providing a glue groove 21, the photovoltaic module 10 is connected to the support plate 20, and a support connection sleeve 30 connected to the support plate 20 is provided and adjacent photovoltaic modules are connected to each other through the support connection sleeve 30. This connection and fixing method avoids the friction and tearing effect of the clamp on the roof and the photovoltaic panel, thereby improving the service life of the photovoltaic module 10. In addition, the bent wave-shaped support plate 20 is used to support the photovoltaic module 10 and connect to the roof, which is lighter than the horizontal whole panel and the need for additional clamps. Semi-flexible crystalline silicon lightweight photovoltaic modules can be used to further reduce the weight of the photovoltaic module, thereby reducing the amount of steel used in the new steel structure building field. In addition, by rationally adjusting the position of the support connection sleeve 30, the connection support sleeve and the support plate 20 cooperate with each other, thereby strengthening the mechanical structural strength of the longitudinal spacing, reducing the deformation of the photovoltaic integrated modular product when subjected to trampling pressure and hail impact pressure, and preventing the hidden cracks of the crystalline silicon cells of the photovoltaic module 10. In addition, the socket connection of the support connection sleeve 30 and the sufficient pressure resistance allow the use of automatic assembly equipment to improve the assembly efficiency. Therefore, the present invention solves the problem in the prior art of the lack of an assembled photovoltaic integrated modular product that is light in weight, strong in pressure resistance, good in waterproof performance, has a long service life, high in solar energy utilization rate, and high in assembly efficiency.
[0060] In addition, the present invention also provides a photovoltaic system, which includes a plurality of the above-mentioned assembled photovoltaic integrated modules. It should be noted that the photovoltaic system absorbs light energy through a plurality of photovoltaic units, performs photovoltaic power generation, and recycles the heat generated by photovoltaic power generation through heat dissipation pipes, thereby achieving a gradient utilization effect of energy, greatly increasing the efficiency of energy utilization, and meeting the needs of building energy conservation. In addition, since the heat dissipation pipe adopts a detachable split connection method, the heat dissipation pipe and its supporting heat recovery device can be set or not as needed. This allows the photovoltaic system to be adjusted according to customer needs, greatly increasing the scope of application of the photovoltaic system.
