Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, and more specifically, to a method for preparing a flexible photovoltaic module with high mechanical strength. Background Technology

[0002] Flexible photovoltaic (PV) modules are the core and most important component of solar power generation systems. Currently, flexible PV modules are lightweight and bendable during the manufacturing process, making them suitable for applications in PV power plants, solar buildings, vehicles, and outdoor equipment. This greatly expands the application of PV modules and has attracted widespread attention.

[0003] Currently, flexible photovoltaic modules on the market often face the following technical problems during the manufacturing, assembly, and installation processes:

[0004] When transporting existing flexible photovoltaic modules to some remote areas, the assembled flexible photovoltaic modules are transported to the area where they need to be installed in advance. However, the large size of the assembled flexible photovoltaic modules makes them difficult to move, which affects the transportation process. In addition, the assembly process of existing flexible photovoltaic modules often requires the use of some external equipment to assemble the frame, making the assembly process too cumbersome and causing inconvenience to the workers installing and assembling them. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a method for manufacturing high mechanical strength flexible photovoltaic modules that can replace the frame assembly method of the frame assembly machine with a simple snap-fit ​​method, so that the flexible photovoltaic modules can be disassembled and transported. This method facilitates the frame assembly and binding of high mechanical strength flexible photovoltaic modules by workers in the absence of a frame assembly machine, and brings certain convenience to workers.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for manufacturing a flexible photovoltaic module with high mechanical strength includes a body module, wherein a sealing component is fitted onto the outer surface of the body module.

[0008] The main body assembly includes two symmetrically arranged first frame members, two second frame members that snap together between the two first frame members, two plug-in members that slide inside the first frame members, a photovoltaic element installed between the first frame members and the second frame members, and fasteners threadedly connected to the first frame members.

[0009] The first frame component includes a rectangular frame with a mounting groove on its side. Rectangular insertion frames are fixed to opposite ends of the rectangular frame. Two symmetrical base plates are fixed to the inner wall of the mounting groove. A pivot is fixed to the top of each of the two base plates. A rocker arm extending into the rectangular insertion frame is rotatably fitted to the circumference of the pivot arm via a torsion spring. Sliding grooves for sliding cooperation with insertion components are provided on opposite sides of the rectangular insertion frame. A positioning hole for insertion cooperation with insertion components is provided on one outer side of the rectangular insertion frame.

[0010] The second frame component includes an adjacent frame, and each of the two opposite ends of the adjacent frame is fixed with a snap-fit ​​frame that engages with the rectangular plug-in frame. A locking hole is provided through one outer side of the snap-fit ​​frame to engage with the plug-in component.

[0011] The present invention is further configured such that: the plug-in component includes two symmetrical sliding plates, a support plate is fixed between the two sliding plates, a plug rod is slidably fitted through the top of the support plate and is plugged into the positioning hole and the locking hole, both ends of the plug rod are dome-shaped, a positioning ring is fixed on the periphery of the plug rod above the support plate, a return spring is fixed between the positioning ring and the support plate and sleeved on the periphery of the plug rod, and the two sliding plates are slidably fitted with two sliding grooves respectively.

[0012] The invention is further configured such that: an L-shaped plate is fixed to the inner wall of the mounting groove between the two base plates, and an internally threaded cylinder is connected through the side of the L-shaped plate.

[0013] The fastener includes a rotating plate, a rotating column fixed to the side of the rotating plate, a first threaded groove rotatably connected to the internal threaded cylinder on the circumferential side of the rotating column, a limit groove at the bottom of the rotating column, a second threaded groove below the first threaded groove on the circumferential side of the rotating column, a sliding ring slidably fitted on the circumferential side of the rotating column, two symmetrical limit rails fixed on the inner wall of the sliding ring, the two limit rails slidably fitted with the limit grooves on the rotating column respectively, and a fixing nut rotatably connected to the second threaded groove.

[0014] The present invention is further configured such that: the photovoltaic component includes a polymer backsheet, a first grid plate is hot-pressed onto the top of the polymer backsheet, a second grid plate is hot-pressed onto the top of the first grid plate, a first encapsulation plate is hot-pressed onto the top of the second grid plate, a photovoltaic array plate is hot-pressed onto the top of the first encapsulation plate, a second encapsulation plate is hot-pressed onto the top of the photovoltaic array plate, and a polymer cover plate is hot-pressed onto the top of the second encapsulation plate.

[0015] The present invention is further configured such that: the grids of the first grid plate and the second grid plate are intersected; the polymer back plate and the polymer cover plate are made of one or more of PET, PE, PVDF, PVF or nylon; and the first encapsulation plate and the second encapsulation plate are made of one of EVA, PVB or TPO.

[0016] The present invention is further configured such that the sealing assembly includes a sealing element and a cover plate element that snaps onto the sealing element.

[0017] The sealing element includes a sealing frame, and a sealing groove is provided on the top of the outer side of the sealing frame.

[0018] The cover plate component includes a cover plate frame, and a sealing rail that engages with the sealing groove is fixed at the bottom of the cover plate frame.

[0019] The present invention is further configured such that: a sealing rubber frame is fixed to the inner wall of the cover frame, and a cross-shaped fixing plate is fixed to the inner wall of the sealing rubber frame.

[0020] The cover frame has isosceles trapezoidal plates fixed on both opposite sides, and the isosceles trapezoidal plates have insertion holes on both opposite inclined surfaces.

[0021] The present invention is further configured such that: two sets of symmetrical side baffles are fixed on both outer sides of the sealing frame, each set of side baffles consists of two baffles, and the two side baffles are symmetrically arranged.

[0022] Each set of side baffles has a slidingly fitted insertion rod that engages with the insertion hole. One end of the insertion rod is fixed with a pull plate, and an elastic spring is fixed between the pull plate and the side baffle, which is sleeved on the circumferential side of the insertion rod. The insertion rod is dome-shaped relative to the other end face.

[0023] The advantages of this invention are: 1. This invention uses a rotating ring to synchronously rotate and fit together on the sides of the two rocker plates, causing the two insert rods to slide on the two support plates respectively. Finally, the round top end of the insert rod is inserted into the positioning hole and the locking hole in sequence, thereby interlocking the two parallel rectangular frames and the two adjacent frames to form a rectangular frame. In the whole process, the simple interlocking method replaces the frame assembly method of the frame assembly machine, making the flexible photovoltaic module detachable for transportation. This makes it convenient for workers to assemble and bind the high mechanical strength flexible photovoltaic module frame without a frame assembly machine, bringing certain convenience to the workers.

[0024] 2. This invention utilizes the sliding engagement between the two inclined surfaces of an isosceles trapezoidal plate and the rounded tips of two insert rods to stretch the elastic spring fixed between the pull plate and the side baffle. This causes the two insert rods to move away from each other in a linear motion until the rounded tips of the two insert rods align with the two insertion holes. At this point, the stretched elastic spring begins to return to its original position, causing the rounded tips of the insert rods to be inserted into the insertion holes. This facilitates the assembly and sealing of the photovoltaic components, which have undergone heat pressing and peripheral encapsulation, before installation. Throughout the process, it is convenient for workers to assemble the entire photovoltaic module, and the scattered components before assembly are easier to handle and transport, providing convenience to the workers.

[0042] Example 1, please refer to Figure 1-13 The present invention provides the following technical solutions:

[0043] A method for manufacturing a flexible photovoltaic module with high mechanical strength, specifically including a body component 1, with a sealing component 2 fitted onto the outer surface of the body component 1; the body component 1 includes two symmetrically arranged first frame members 3, two second frame members 4 snapped together between the two first frame members 3, two plug-in members 5 slidably disposed inside the first frame members 3, a photovoltaic component 6 installed between the first frame members 3 and the second frame members 4, and fasteners 7 threadedly connected to the first frame members 3; the first frame members 3 include a rectangular frame 301, with a mounting groove 302 opened on the side of the rectangular frame 301, and rectangular plug-in frames 303 fixed to opposite end faces of the rectangular frame 301, the inner wall of the mounting groove 302... Two symmetrical base plates 304 are fixed, and a rotating shaft 305 is fixed to the top of each base plate 304. The rotating shaft 305 is rotated and engaged by a torsion spring on its circumferential side with a rocker plate 306 extending into the interior of a rectangular insertion frame 303. The rectangular insertion frame 303 has sliding grooves 307 through which it slides and engages with the insertion piece 5 on both opposite sides. A positioning hole 308 through which it engages with the insertion piece 5 is provided on one outer side of the rectangular insertion frame 303. The second frame member 4 includes an adjacent frame 401. A snap-fit ​​frame 402 is fixed to each of the opposite end faces of the adjacent frame 401 and engages with the rectangular insertion frame 303. A locking hole 403 through which it engages with the insertion piece 5 is provided on one outer side of the snap-fit ​​frame 402.

[0044] Furthermore, the connector 5 includes two symmetrical sliding plates 501, with a support plate 502 fixed between the two sliding plates 501. A rod 503, which is slidably fitted through the top of the support plate 502 and engages with the positioning hole 308 and the locking hole 403, is attached to the top of the support plate 502. Both ends of the rod 503 are dome-shaped. A positioning ring 504 is fixed to the periphery of the rod 503 above the support plate 502. A return spring 505, which is sleeved between the positioning ring 504 and the support plate 502, is fixed to the periphery of the rod 503. The two sliding plates 501 are slidably fitted with two sliding grooves 307 respectively. An L-shaped plate 309 is fixed to the inner wall of the mounting groove 302 between the two base plates 304. The side of the L-shaped plate 309... The internally threaded cylinder 310 is connected through the fastener 7, which includes a rotating plate 701. A rotating column 708 is fixed on the side of the rotating plate 701. A first threaded groove 702 is opened on the circumferential side of the rotating column 708, which is threadedly rotatably connected to the internally threaded cylinder 310. A limiting groove 703 is opened at the bottom of the rotating column 708. A second threaded groove 704 is opened on the circumferential side of the rotating column 708 below the first threaded groove 702. A sliding ring 705 is slidably fitted on the circumferential side of the rotating column 708. Two symmetrical limiting rails 706 are fixed on the inner wall of the sliding ring 705. The two limiting rails 706 are slidably fitted with the limiting grooves 703 on the rotating column 708 respectively. A fixing nut 707 is threadedly rotatably connected to the second threaded groove 704.

[0045] The specific application of this embodiment is as follows: After the photovoltaic component 6 undergoes hot pressing, each component is transported to the area to be installed. Then, the two rectangular frames 301 are placed symmetrically and parallel. After symmetrical parallel placement, the two sliding plates 501 in the connector 5 are slidably inserted into the two sliding grooves 307, thus completing the sliding insertion process of the connector 5. After the sliding insertion process of the connector 5 is completed, one rounded top end of the plug rod 503 in the connector 5 is in a state of contact with the side of the rocker plate 306. Then, the snap-fit ​​frames 402 fixed to the opposite end faces of the adjacent frame 401 are snapped into the rectangular plug-fit frames 303 fixed to one side of the two rectangular frames 301, thus completing the connection between the two adjacent frames 401 and the two symmetrically parallel frames 307. During the edge-sealing and snap-fit ​​assembly process between the rectangular frames 301, and between the two adjacent frames 401 and the two symmetrically parallel rectangular frames 301, the rotating plate 701 is rotated, causing the first threaded groove 702 on the circumferential side of the rotating column 708 to rotate threadedly on the inner wall of the inner threaded cylinder 310. (After the first threaded groove 702 on the circumferential side of the rotating column 708 rotates threadedly on the inner wall of the inner threaded cylinder 310 to a certain distance, the threaded rotation between the second threaded groove 704 on the rotating column 708 and the inner threaded cylinder 310 disappears and is inside the L-shaped plate 309. At this time, the threaded rotation between the first threaded groove 702 and the inner threaded cylinder 310 begins. Subsequently, before continuing to rotate the rotating column 708, the sliding...) Ring 705 is slidably inserted into limiting groove 703 via limiting rail 706, so that the top of limiting rail 706 and the inner top of limiting groove 703 are in a mutually fitting state. Finally, the sliding ring 705 is limited and fixed by the threaded rotation connection between fixing nut 707 and second threaded groove 704, preventing the sliding ring 705 from sliding on the circumferential side of rotating column 708 when the two rocker plates 306 are rotated and squeezed later. This causes the sliding ring 705, which is slidably positioned on the circumferential side of rotating column 708, to synchronously approach the side of the two rocker plates 306, driving the sliding ring 705, which is slidably positioned on rotating column 708, to synchronously rotate and fit together on the side of the two rocker plates 306, thereby driving the two rocker plates 306 to move closer to each other. 6. The two rotating shafts 305, under the action of torsion springs, slowly tilt upwards, creating a compressive force on the two plug-in parts 5. This causes the return springs 505 in the two plug-in parts 5 to stretch synchronously, causing the two insertion rods 503 to slide on the two support plates 502. Ultimately, the rounded top end of the insertion rod 503 is inserted into the positioning hole 308 and the locking hole 403 in sequence, thereby engaging the two parallel rectangular frames 301 and the two adjacent frames 401 to form a rectangular frame. This provides initial engagement and locking of the periphery of the hot-pressed photovoltaic component 6 (the engagement and locking process between the photovoltaic component 6 and the two rectangular frames 301 and the two adjacent frames 401).Specifically, the modules are engaged using insert grooves created on the outer surfaces of the two rectangular frame pieces 301 and the two adjacent frame pieces 401. The thickness of these insert grooves is the same as, or slightly greater than, the thickness of the photovoltaic element 6 after hot pressing. This facilitates subsequent sealing operations, forming a complete, high-mechanical-strength flexible photovoltaic module. Throughout the process, this simple snap-fit ​​method replaces the frame assembly method of a framing machine, allowing the flexible photovoltaic module to be disassembled and transported. This makes it convenient for workers to assemble and bind the high-mechanical-strength flexible photovoltaic module without a framing machine, providing them with greater convenience.

[0046] Example 2, please refer to Figure 1-13 This second embodiment is an improvement on the first embodiment as follows: Specifically, the photovoltaic component 6 includes a polymer backplate 601, a first grid plate 602 hot-pressed onto the top of the polymer backplate 601, a second grid plate 603 hot-pressed onto the top of the first grid plate 602, a first encapsulation plate 604 hot-pressed onto the top of the second grid plate 603, a photovoltaic array plate 605 hot-pressed onto the top of the first encapsulation plate 604, a second encapsulation plate 606 hot-pressed onto the top of the photovoltaic array plate 605, and a polymer cover plate 607 hot-pressed onto the top of the second encapsulation plate 606; the grids of the first grid plate 602 and the second grid plate 603 are intersectingly distributed; the polymer backplate 601 and the polymer cover plate 607 are made of one or more of PET, PE, PVDF, PVF, or nylon; the first encapsulation plate 604 and the second encapsulation plate 606 are made of one of EVA, PVB, or TPO; the sealing assembly 2 includes a sealing element 8 and a cover plate 9 snapped onto the sealing element 8; the sealing element 8 includes a sealing frame 801, and the top of the sealing frame 801 has an opening... The sealing groove 802; the cover plate component 9 includes a cover plate frame 901, the bottom of which is fixed with a sealing rail 902 that engages with the sealing groove 802; a sealing rubber frame 905 is fixed to the inner wall of the cover plate frame 901, and a cross fixing plate 906 is fixed to the inner wall of the sealing rubber frame 905 (the cross fixing plate 906 is used to enhance the structural stability of the sealing rubber frame 905); isosceles trapezoidal plates 903 are fixed to both opposite sides of the cover plate frame 901, and insertion holes 904 are opened on both opposite inclined surfaces of the isosceles trapezoidal plates 903; sealing Two sets of symmetrical side baffles 803 are fixed on the two outer sides of the frame 801. There are two side baffles 803 in each set, and the two side baffles 803 are symmetrically arranged. Each side baffle 803 has a sliding engagement rod 804 that is engaged with the insertion hole 904. A pull plate 805 is fixed to one end of the insertion rod 804. An elastic spring 806 is fixed between the pull plate 805 and the side baffle 803 and is sleeved on the circumferential side of the insertion rod 804. The other end of the insertion rod 804 is dome-shaped.

[0047] The specific application of this embodiment 2 is as follows: In the process of hot pressing the photovoltaic component 6, the polymer backplate 601, the first grid plate 602, the second grid plate 603, the first encapsulation plate 604, the photovoltaic array plate 605, the second encapsulation plate 606, and the polymer cover plate 607 are hot pressed layer by layer to form the photovoltaic component 6 that needs to be assembled.

[0048] During the hot pressing process, firstly, multiple solar photovoltaic cells are connected in series to form a photovoltaic array panel 605 (solar photovoltaic cells are existing technology and will not be elaborated on here). Next, a polymer backplate 601, a first grid plate 602, and a second grid plate 603 are stacked sequentially from bottom to top. Then, the photovoltaic array panel 605 formed in the initial series connection is stacked between a first encapsulation plate 604 and a second encapsulation plate 606 to form the required solar heat-absorbing layer. Next, the solar heat-absorbing layer is stacked on top of the second grid plate 603, so that the bottom of the first encapsulation plate 604 in the solar heat-absorbing layer is in contact with the top of the second grid plate 603. After the contact is completed, a polymer cover plate 607 is stacked on top of the solar heat-absorbing layer, so that the bottom of the polymer cover plate 607 is in contact with the second encapsulation plate in the solar heat-absorbing layer. The tops of 606 contact each other to form the required laminate. Finally, after the laminate is stacked, it is flipped so that the original upward side is facing down and placed in a laminator to complete the hot lamination process (the laminator is existing technology and is not shown in the figure, so it will not be described in detail here. During the hot pressing process, the hot pressing temperature is 130 degrees Celsius, the vacuum time is five minutes, the pressure after vacuum is -10 kPa, and the delay is 600-1800 seconds). During the hot pressing process, the first encapsulation plate 604 and the second encapsulation plate 606 fuse together to wrap the photovoltaic array plate 605, thereby isolating moisture and air. During the hot pressing process, the first encapsulation plate 604 will penetrate the first grid plate 602 and the second grid plate 603 and be tightly bonded to the polymer backing plate 601 below.

[0049] After the hot-pressing process is completed, the photovoltaic component 6 is peripherally encapsulated and embedded. After the peripheral encapsulation and embedding are completed, sealing is performed. During the sealing process, the peripherally encapsulated photovoltaic component 6 is placed inside the sealing frame 801. Subsequently, the cover frame 901 is placed on the outer top of the sealing frame 801. During the covering process, the elastic spring 806, which is fixedly connected between the pull plate 805 and the side baffle 803, is stretched through the sliding engagement between the two inclined surfaces of the isosceles trapezoidal plate 903 and the round tops of the two inserted round rods 804. The two plug-in round rods 804 move away from each other in a straight line until the round tips of the two plug-in round rods 804 are aligned with the two plug holes 904. Then, the stretched elastic spring 806 begins to return to its original position, causing the round tips of the plug-in round rods 804 to be inserted into the plug holes 904. This is to assemble and seal the photovoltaic component 6, which has been hot-pressed and has completed peripheral encapsulation, before installation. Throughout the process, it is convenient for staff to assemble the entire photovoltaic module, and the scattered parts before assembly are easy for staff to handle and transport, bringing certain convenience to the staff.
