Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, and in particular to a steel-framed photovoltaic module and its production apparatus. Background Technology

[0002] Currently, aluminum alloy profiles are mainly used to support the frames of photovoltaic modules. However, aluminum alloy profiles are expensive, and large-sized aluminum frames have poor mechanical load-bearing capacity, making it difficult to meet the requirements for protecting the photovoltaic unit laminates. Therefore, in some cases, steel frames are used instead of aluminum alloy profiles as the main frame for photovoltaic module installation.

[0003] In the prior art, Chinese invention patent applications with publication numbers CN116232204A, CN116365986A, and CN116365984A disclose different types of steel frames for mounting photovoltaic modules. These steel frames all have cavities for inserting corner brackets. Adjacent steel frames are fixedly connected by the locking teeth between the corner brackets and the cavities, or by using fasteners such as rivets and screws. However, the cavities in the steel frames increase the material usage, increasing both production costs and weight, thus increasing the overall weight of the photovoltaic module and hindering its handling and installation. Furthermore, when using fasteners such as locking teeth, screws, and rivets to connect adjacent steel frames, with increased use, the photovoltaic module is affected by outdoor environmental factors such as sun, rain, wind, and vibration, causing the fasteners to loosen and reducing the structural stability of the photovoltaic module.

[0004] Therefore, it is necessary to improve the existing steel-framed photovoltaic modules. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects in the prior art and provide a steel-framed photovoltaic module and its production device that reduces the amount of production materials used to reduce weight and cost while ensuring long-term structural stability.

[0006] To address the aforementioned technical problems, the present invention provides a steel-framed photovoltaic module, comprising: A photovoltaic unit, wherein the photovoltaic unit has a light-receiving surface and a back-lighting surface arranged opposite to each other along its own thickness direction; A frame assembly, comprising steel profiles connected end to end, each steel profile having an assembly groove extending along its own length and sealed to the outer circumferential sidewall of the photovoltaic unit. A sliding strip slides along the length of the steel section and surrounds the steel section to form a casting channel. Among the casting channels corresponding to two adjacent steel sections, the two casting channels are connected to form a bent forming channel. The forming channel is used to inject a curable liquid material so that the curable liquid material is solidified and formed into a rigid corner connector to fix and connect two adjacent steel sections.

[0007] Preferably, in order to strengthen the connection between the slide bar and the steel section, the slide bar is a groove facing the steel section, and the groove includes a first space and a second space. The first space and the second space are respectively adjacent to the bottom and the opening of the groove. The width of the first space is greater than the width of the second space. One side of the steel section passes through the opening of the groove and enters the first space.

[0008] Preferably, in order to ensure structural compactness, reduce the amount of solidifiable liquid material overflowing when injecting solidifiable liquid material into the molding channel, and reduce the area occupied by the installation, the outer side wall of the steel profile includes a backlight side wall, which is disposed on the side of the backlight surface away from the light-receiving surface, and the slide bar is sealed to the backlight side wall.

[0009] Preferably, in order to reduce the amount of production materials used in the steel profile, lower production costs, reduce weight, and facilitate transportation and installation, the steel profile includes an integrally connected U-shaped part and a guide part. Both the U-shaped part and the guide part extend along the length direction of the steel profile. The guide part is located on the side of the U-shaped part away from the light-receiving surface and slides in cooperation with the slide bar.

[0010] Preferably, in order to facilitate the curing and molding of the corner connector, both ends of the molding channel are set upwards during the casting and molding of the corner connector.

[0011] To address the aforementioned technical problems, the present invention also provides a production apparatus for steel-framed photovoltaic modules, comprising: frame; The rotating assembly and the clamping assembly are connected to the frame via the rotating assembly. The clamping assembly is used to clamp the steel frame assembly described in any of the above technical solutions from the outside. The rotating assembly drives the clamping assembly to rotate intermittently so that each pair of adjacent steel sections slides downwards to a sealed fit. When the two slides are sealed fit, the pouring channels corresponding to the two adjacent steel sections are connected to form a bent forming channel with both ends facing upwards.

[0012] Preferably, in order to increase the length of the corner connector to strengthen the fixed contact area between the corner connector and the two adjacent sliders and enhance the structural stability of the photovoltaic module, when the two sliders are sealed together, the two ends of the forming channel are located on the same horizontal plane.

[0013] Preferably, in order to facilitate the placement and removal of photovoltaic modules on the production device, an adjustment component is also provided between the clamping component and the frame. The adjustment component drives the clamping component to rotate between the first station and the second station. At the first station, the clamping component is horizontally positioned with the backlight facing upwards, corresponding to the fixed frame component.

[0014] Preferably, in order to increase the amount of curable liquid material injected into the molding channel, enhance the contact area between the cured corner connector and the two adjacent slides, and thus strengthen the structural strength of the photovoltaic module, in the second station, the backlight surface of the frame component corresponding to the clamping component is parallel to the vertical direction.

[0015] Preferably, in order to enhance the clamping effect on the photovoltaic module and prevent the photovoltaic module from detaching from the clamping assembly, the clamping assembly includes a clamping member for clamping the profile steel. The clamping member includes a first clamping plate and a second clamping plate. When the clamping assembly clamps and fixes the frame assembly, the first clamping plate abuts against one of the side walls of the profile steel away from the photovoltaic unit, and the second clamping plate abuts against one of the side walls of the profile steel near the backlight surface of the photovoltaic unit.

[0016] In summary, compared with the prior art, the steel frame photovoltaic module and its production device of the present invention form a molding channel by interconnecting two adjacent steel profiles and corresponding sliding strips to form a casting channel. A curable liquid material is injected into the molding channel to form a corner connector, which connects the two adjacent steel profiles as a whole. This ensures the long-term stability of the photovoltaic module structure and avoids abnormalities such as loosening of the photovoltaic module under long-term use after it is fixed by fasteners such as clips and screws.

Detailed Implementation

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] like Figures 1-6 As shown, the steel-framed photovoltaic module of the present invention includes: Photovoltaic unit 100, having a light-receiving surface 101 and a backlighting surface 102 arranged opposite to each other along its own thickness direction; The frame assembly includes steel profiles 200 connected end to end, each steel profile 200 having an assembly groove 201 extending along its own length and sealed to the outer circumferential sidewall of the photovoltaic unit 100. A slide bar 300 slides along the length of the steel section 200 and encloses the steel section 200 to form a casting channel 301. The casting channels 301 corresponding to two adjacent steel sections 200 are connected to form a bent forming channel. The forming channel is used to inject a curable liquid material so that the curable liquid material is solidified into a rigid corner connector 400 to fix the two adjacent steel sections 200 together.

[0020] In the steel-framed photovoltaic module of the present invention, the photovoltaic unit 100 includes a cover plate 103, a first encapsulant layer 104, a battery layer 105, a second encapsulant layer 106, and a back plate 107 that are stacked in sequence. Both the cover plate 103 and the back plate 107 are glass plates. The side of the cover plate 103 away from the battery layer 105 is the light-receiving surface 101 of the photovoltaic unit 100, that is, the front side of the photovoltaic unit 100, while the side of the back plate 107 away from the battery layer 105 is the back side 102 of the photovoltaic unit 100, that is, the back side of the photovoltaic unit 100.

[0021] The photovoltaic unit 100 is generally a flat cuboid. Therefore, there are four steel profiles 200 in the frame assembly. The four steel profiles 200 are connected in sequence to form a rectangular frame. Of course, the photovoltaic unit 100 can also be a triangular prism, pentagonal prism, or other structural form of the frame. Correspondingly, the number of steel profiles 200 is adjusted so that the number of steel profiles 200 is equal to the number of sidewalls on the outer periphery of the photovoltaic unit 100 and corresponds one-to-one. The steel profiles 200 are connected end to end to form a closed loop frame surrounding the photovoltaic unit 100. The mounting groove 201 on the steel profile 200 is used for inserting one sidewall of the photovoltaic unit 100. In order to ensure the sealing between the photovoltaic unit 100 and the frame assembly, an elastic sealing strip 900 is provided between the inner wall of the mounting groove 201 and the photovoltaic unit 100. The sealing strip 900 is preferably made of rubber or silicone.

[0022] Each steel profile 200 has two sliding strips 300. The material of the sliding strips 300 is not limited; they can be metal alloys, plastics, glass, etc. The sliding strips 300 and the steel profile 200 enclose a casting channel 301. As the sliding strips 300 slide on the steel profile 200, their positions change, and the positions of the casting channels 301 also change. When the two sliding strips 300 on each steel profile 200 slide to the point where their ends are flush with the two ends of the steel profile 200, in this photovoltaic module, for any two adjacent steel profiles 200, the ends of the two sliding strips 300 corresponding to the contact ends of the two steel profiles 200 seal against each other. At this time, the two casting channels 301 enclosed by the two sliding strips 300 and the two steel profiles 200 form a bent molding channel. Specifically, the molding channel is an L-shaped or V-shaped molding channel with an angle. At this time, a curable liquid material can be injected into the molding channel, so that the liquid material... The liquid material is filled into the molding channel and, after solidification into a rigid fixing material, forms a rigid corner connector 400. The corner connector 400 is also filled between the two slide bars 300 and the two profiles 200, thereby fixing the two adjacent slide bars 300 together. Since the sliding directions of the two slide bars 300 are not consistent, after the corner connector 400 is solidified, the two slide bars 300 can no longer slide on the two profiles 200 they originally corresponded to, thus fixing the two adjacent profiles 200 corresponding to the two slide bars 300. Compared with using screws, rivets, or clips to fix the corner bracket to the cavity of the profile 200 to connect the two adjacent profiles 200, in this invention, after the corner connector 400 is solidified, it is integrally connected with the two adjacent slide bars 300, thereby avoiding loosening after long-term use and ensuring the structural stability of the steel frame photovoltaic module for long-term use.

[0023] It should be noted that the corner connector 400 can be made of various curable liquid materials, such as liquid curing adhesives, resins, concrete slurry, polyurethane, etc., with polyurethane being the preferred choice. Polyurethane is initially liquid before foaming, and after foaming, it forms a solid, rigid polyurethane within the molding channel formed by the two pouring channels 301. Polyurethane is corrosion-resistant, lightweight, and has high structural strength. While ensuring the secure connection of two adjacent steel profiles 200, it also reduces the overall weight of the photovoltaic module compared to concrete. Furthermore, the cost of rigid polyurethane foam is lower. Compared to steel, this is cheaper. In addition, when the slider 300 is made of metal materials such as aluminum alloy or steel, the surface of the foamed rigid polyurethane can form a tight bond with the metal surface to a certain extent, thereby providing good adhesion and bonding strength. In this way, the cured corner connector 400 is fixedly connected to the inner wall of the molding channel. Specifically, the cured foamed polyurethane is firmly connected to two adjacent sliders 300 and two adjacent steel profiles 200, so that the two adjacent steel profiles 200 are connected as one, thereby ensuring the structural strength of the steel frame photovoltaic module of the present invention.

[0024] A further improvement is that the slide bar 300 is a slide groove facing the steel section 200. The groove space includes a first space and a second space. The first space and the second space are adjacent to the bottom and opening of the groove, respectively. The width of the first space is greater than the width of the second space. One side of the steel section 200 passes through the opening of the groove and enters the first space.

[0025] With the above structure, the slider 300 is slid from the end of the steel section 200 into the middle of the steel section 200, so that one side of the steel section 200 enters the first space through the groove. Since the width of the first space is greater than the width of the second space, the slider 300 and the steel section 200 cannot separate from each other along the length direction perpendicular to both of them, thus realizing the limiting connection between the slider 300 and the steel section 200. The slider 300 can only slide along the end of the steel section 200 and separate from the end of the steel section 200. When the four steel sections 200 are connected end to end to form a rectangular frame structure, the two ends of the steel section 200 are closed, so that the slider 300 cannot separate from the steel section 200.

[0026] A further improvement is that the outer wall of the steel profile 200 includes a backlight sidewall 202, which is located on the side of the backlight surface 102 away from the light-receiving surface 101, and the slide bar 300 is sealed to the backlight sidewall 202.

[0027] With the above structure, the slide bar 300 is sealed and fitted to the backlight sidewall 202 of the steel profile 200. Furthermore, the width of the slide bar 300 is less than or equal to the width of the backlight sidewall 202. When the photovoltaic module is installed horizontally, the projection of the slide bar 300 on the horizontal plane is located within the projection of the backlight sidewall 202, thereby reducing the horizontal installation area of ​​the photovoltaic module. This makes it easier to install more photovoltaic modules on a limited installation surface to increase photovoltaic power generation. In addition, since the slide bar 300 is sealed and fitted to the backlight sidewall 202, when injecting curable liquid material into the molding channel, the amount of liquid material overflowing from between the slide bar 300 and the backlight sidewall 202 can be reduced, allowing the liquid material to solidify and form in the molding channel, thus fixing the two adjacent steel profiles 200 together.

[0028] A further improvement is that the profile 200 includes an integrally connected U-shaped portion 203 and guide portion 204. Both the U-shaped portion 203 and guide portion 204 extend along the length direction of the profile 200. The guide portion 204 is located on the side of the U-shaped portion 203 away from the light-receiving surface 101 and slides in cooperation with the slide bar 300.

[0029] Specifically, the steel section 200 consists of two parts: a U-shaped section 203 and a guide section 204, as shown below. Figure 5 and Figure 6 As shown, the U-shaped part 203 has an integrally formed assembly groove 201 for sealing connection with one of the side walls of the photovoltaic unit 100; the guide part 204 has an inverted T-shaped cross section, the guide part 204 is integrally connected with the U-shaped part 203, and forms two clamping grooves arranged back to back; the slide bar 300 has two horizontal arms spaced apart on the side adjacent to the profile steel 200, and the two horizontal arms are sealed to the inner walls of the two clamping grooves, thereby realizing the sliding connection between the slide bar 300 and the profile steel 200, while the slide bar 300 is sealed to the backlight side wall 202. At the same time, the slide bar 300 and the backlight side wall 202 form a casting channel 301. When two adjacent casting channels 301 of two adjacent profile steel 200 are connected to each other to form a forming channel, the end faces of the two adjacent profile steel 200 are sealed and fitted, and the ends of the two adjacent slide bars 300 are sealed and fitted.

[0030] For ease of assembly, in this invention, the planes containing the two end faces of the profile 200 are at an angle of 45° to their own length direction and are perpendicular to each other. The planes containing the two end faces of the slide bar 300 are at an angle of 45° to their own length direction and are perpendicular to each other. When the slide bar 300 is installed on the profile 200 and slidably connected to the profile 200, the two end faces of the slide bar 300 are parallel to the corresponding two end faces of the profile 200, that is, one end face of the slide bar 300 is parallel to one end face of the adjacent profile 200.

[0031] A further improvement is that, during the casting of the corner connector 400, both ends of the molding channel are set upwards.

[0032] When injecting curable liquid material into the molding channel, adjust the spatial position and angle of the photovoltaic module so that both ends of the molding channel are facing upwards. This makes it convenient to inject the curable liquid material into the molding channel from either end or from both ends. After the liquid material has cured and formed into a corner connector 400, fix two adjacent steel profiles 200 together. In this way, when injecting the curable liquid material, there is no need to seal the ends of the molding channel, making the operation more convenient.

[0033] like Figures 7-13 As shown, the present invention also provides a production apparatus for steel-framed photovoltaic modules, comprising: 500 racks; The rotating assembly 600 and the clamping assembly 700 are connected to the frame 500 via the rotating assembly 600. The clamping assembly 700 is used to clamp the aforementioned steel frame assembly from the outside. The rotating assembly 600 drives the clamping assembly 700 to rotate intermittently, so that each pair of adjacent steel profiles 200 slides downwards to a sealed fit with the corresponding two adjacent slide bars 300. When the two slide bars 300 are sealed fit, the pouring channels 301 corresponding to the two adjacent steel profiles 200 are connected to form a bent forming channel with both ends facing upwards.

[0034] When using the production apparatus of the present invention, the photovoltaic module is placed on the clamping assembly 700. After the photovoltaic module is clamped and fixed from the outside by the clamping assembly 700, the clamping assembly 700 is driven to rotate intermittently by the rotating assembly 600, thereby causing the photovoltaic module to rotate intermittently. The corner positions of the photovoltaic module are adjusted so that the four corners of the photovoltaic module face downwards in sequence. When the photovoltaic module rotates to the point where one of its corners faces downwards and is located at the bottom position, the sliding strips 300 on the two adjacent profiles 200 corresponding to that corner slide downwards along the profiles 200 until they slide to the end of the profiles 200. At this time, the ends of the two sliding strips 300 are sealed and fitted together, so that the two sliding strips 300 and the two profiles 200 enclose a V-shaped forming channel (e.g., Figure 13As shown in the diagram, a curable liquid material is injected into the molding channel. After the liquid material solidifies and forms a corner connector 400, the photovoltaic module is driven to rotate again, causing the other corners of the photovoltaic module to rotate to the bottom position in sequence. This allows the two sliding strips 300 corresponding to the corner to slide down along their respective steel profiles 200 until they are sealed and fitted. The two corresponding pouring channels 301 are connected in sequence to form a V-shaped molding channel for injecting the curable liquid material, which is then solidified and formed into a corner connector 400 that fixes the two steel profiles 200 corresponding to the corner. After this operation is repeated four times, the four steel profiles 200 are finally connected end to end in sequence. The four formed corner connectors 400 strengthen the connection between the steel profiles 200, preventing loosening between adjacent steel profiles 200 after long-term use of the photovoltaic module, which would affect the structural performance of the photovoltaic module.

[0035] A further improvement is that when the two slide bars 300 are sealed together, the two ends of the forming channel are located on the same horizontal plane.

[0036] like Figure 13 As shown, when the rotating component 600 drives the clamping component 700 to rotate, adjusting the position of the photovoltaic module, the slide bars 300 corresponding to the two profiles 200 at one corner of the photovoltaic module slide downwards at their lowest point. The two slide bars 300 seal and fit together, forming a bent forming channel with the two profiles 200. The two ends of the forming channel are located on the same horizontal plane, so that the two ends of the curable corner connector 400 can be flush with the two ends of the forming channel at most. This increases the size of the corner connector 400, thereby increasing the contact area and connection strength between the corner connector 400 and the two profiles 200 and the two slide bars 300, thus strengthening the structural strength of the photovoltaic module.

[0037] A further improvement is that an adjustment component 800 is provided between the clamping component 700 and the frame 500. The adjustment component 800 drives the clamping component 700 to rotate between the first station and the second station. In the first station, the clamping component 700 is horizontally positioned to clamp the fixed frame component with the backlight surface 102 facing upward. In the second station, the backlight surface 102 of the clamping component 700 to clamp the fixed frame component is parallel to the vertical direction.

[0038] Specifically, such as Figure 12 As shown, in Figure 12 In state (a), the clamping component 700 is adjusted to the first position by the adjusting component 800, so that the back surface 102 of the photovoltaic module is facing upward and placed horizontally on the clamping component 700, and then... Figure 12 (b) After the clamping component 700 clamps and fixes the photovoltaic module, as... Figure 12(c) The clamping component 700 is adjusted to the second position by the adjusting component 800 so that the back surface 102 of the photovoltaic module is parallel to the vertical direction. Then, the clamping component 700 is rotated by the rotating component 600 so that each corner of the photovoltaic module is rotated to the lowest position in sequence. At this time, a curable liquid material is injected into the forming channel at the lowest position to ensure that the liquid material fills the entire forming channel and finally solidifies into a corner connector 400 to fix two adjacent steel profiles 200 together. After the four steel profiles 200 are fixedly connected end to end in sequence, the clamping component 700 is adjusted to the first position by the adjusting component 800 so that the photovoltaic module is kept horizontal. Then, the clamping is released so that the photovoltaic module can be taken out.

[0039] In this invention, the frame 500 includes a horizontal base 501, and a support leg 502 is provided below the base 501 to ensure that the base 501 has a certain height so that the corners of the photovoltaic module do not touch the ground when the rotating component 600 drives the photovoltaic module to rotate; a rotating seat 503 is provided at one end of the base 501.

[0040] The steering assembly 800 is disposed above the base 501. The steering assembly 800 includes a steering frame 801, a steering cylinder 802, and a connecting rod 803. A rotating shaft 8011 is fixed on the steering frame 801. The rotating shaft 8011 rotates around its own axis on the rotating seat 503. The cylinder of the steering cylinder 802 is fixed above the base 501. The piston rod is connected to the steering frame 801 through the connecting rod 803. The clamping assembly 700 is connected to the steering frame 801 through the rotating assembly 600.

[0041] The extension and retraction of the piston rod of the directional cylinder 802 acts on the connecting rod 803, which in turn drives the directional frame 801 to rotate around the axis of the rotating shaft 8011, allowing the clamping assembly 700 to flexibly switch and adjust between the first and second working positions.

[0042] The rotating assembly 600 includes a motor 601, a gear 602, a gear ring 603, and a bearing 604. The outer ring of the bearing 604 and the housing of the motor 601 are both fixed on the steering frame 801. The inner ring of the bearing 604 is fixedly connected to the gear ring 603. The clamping assembly 700 is connected to the gear ring 603. The output end of the motor 601 is fixedly connected to the coaxial centerline of the gear 602. The gear 602 meshes with the gear ring 603.

[0043] Motor 601 drives gear 602 to rotate. Gear 602 acts on gear ring 603 that meshes with it. Under the support of bearing 604, gear ring 603 rotates around its own axis, thereby driving clamping component 700 to rotate, changing the angular position of clamping component 700, and thus changing the angular position of the photovoltaic module clamped and fixed by clamping component 700.

[0044] A further improvement is that the clamping assembly 700 includes a clamping member 701 for clamping the profile 200. The clamping member 701 includes a first clamping plate 7011 and a second clamping plate 7012. When the clamping assembly 700 clamps the fixed frame assembly, the first clamping plate 7011 abuts against one of the side walls of the profile 200 away from the photovoltaic unit 100, and the second clamping plate 7012 abuts against one of the side walls of the profile 200 near the backlight surface 102 of the photovoltaic unit 100.

[0045] Specifically, the clamping assembly 700 includes a support frame 702 for placing photovoltaic modules. The support frame 702 is provided with multiple clamping units, which surround the four sides of the photovoltaic modules and are used to clamp the photovoltaic modules from the four sides to fix the photovoltaic modules to the support frame 702. Specifically, the clamping unit includes a clamping cylinder 704 provided on the side of the support frame 702 adjacent to the directional frame 801. The cylinder of the clamping cylinder 704 is fixedly connected to the back of the support frame 702, and the piston rod is fixedly connected to the connecting plate 7031. A slider 703 is fixed on the connecting plate 7031. The support frame 702 is provided with a strip-shaped sliding opening 7021 extending along the axial direction of the clamping cylinder 704. The slider 703 slides inside the sliding opening 7021. The clamping member 701 is fixedly connected to the slider 703 and is provided on the side of the support frame 702 away from the directional frame 801.

[0046] The clamping component 701 is a Z-shaped clamping plate, including an integrally connected second clamping plate 7012, a first clamping plate 7011, and an adhesive plate 7013. The adhesive plate 7013 is attached to the support frame 702 and fixedly connected to the side of the slider 703 away from the connecting plate 7031. When clamping and fixing the photovoltaic module, the first clamping plate 7011 faces the photovoltaic unit 100 and abuts against one of the side walls of the profile 200 away from the photovoltaic unit 100, while the second clamping plate 7012 abuts against the backlight side wall 202 of the profile 200. The side of the second clamping plate 7012 away from the first clamping plate 7011 abuts against the guide part 204, thereby ensuring that the clamping component 700 can firmly clamp and fix the photovoltaic module and prevent the photovoltaic module from falling off the support frame 702.

[0047] The above description is only a preferred embodiment of the present invention.
