Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic modules, and particularly relates to an aluminum alloy frame for a flat, firm and easily installed solar photovoltaic panel. Background Art

[0002] The aluminum alloy frame of a solar photovoltaic panel is a component of a solar panel, usually made of aluminum alloy, used to protect the edges of the solar panel and enhance its structural strength.

[0003] Existing frames generally consist of two long frames and two short frames. There are the following several ways to assemble the frames. The first is to apply glue inside the frame and clamp the frame on the side of the photovoltaic panel. Although this method is simple to operate, it is more troublesome to disassemble later. The second is to use bolts and nuts to fix the diagonals of the frame. This method has a low disassembly and assembly efficiency. The third is to use a toothed corner piece. By making the corner piece have an interference fit with the two frames, the teeth on the corner piece squeeze the inner wall of the frame to form a fixed state. This connection method has poor stability, and the connection part is prone to looseness. Moreover, the corner piece is likely to damage the inner wall of the frame after disassembly, resulting in the frame being unable to be reused. The fourth is the combination of bolts and corner pieces for installation. This installation method requires the cooperation of bolts and nuts, and the disassembly and assembly efficiency is low. In summary, the above assembly methods have low efficiency and are likely to damage the frame, resulting in the frame being unable to be reused. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum alloy frame for a flat, firm and easily installed solar photovoltaic panel, aiming to solve the technical problems of low efficiency of the existing assembly methods and easy damage to the frame.

The long side and the short side are collectively referred to as the frame body. Both ends of the frame body are inclined surfaces. The frame further includes: A corner piece. A partition is arranged inside the frame body. The space between the partition and the end of the frame body forms an installation groove. Both ends of the corner piece are respectively installed in the installation grooves of the two frame bodies, and the end of the corner piece abuts against the partition. A rotating rod. The rotating rod is rotatably installed on the outer surface of the frame body and extends into the installation groove. A through hole is formed in the part of the corner piece located in the installation groove. The rotating rod is sleeved in the through hole.

[0006] Preferably, as the above technical solution, the locking assembly includes a ratchet wheel and a ratchet tooth. The periphery of the rotating rod is fixed with the ratchet wheel. The ratchet wheel is located in the movable groove. A ratchet tooth is also rotatably installed in the movable groove. The movable end of the ratchet tooth abuts in the tooth groove of the ratchet wheel. An elastic member II is connected between one side of the ratchet tooth and the movable groove. A dial is arranged on one side of the ratchet tooth. A through groove is formed on the surface of the frame body, and the through groove is communicated with the movable groove. The dial extends out of the frame body from the through groove.

[0007] Preferably, as the above technical solution, a plurality of limiting blocks are arranged in the installation groove. The limiting blocks are perpendicular to the corner fitting. A plurality of limiting grooves are formed in the part of the corner fitting located in the installation groove, and the limiting blocks are stuck in the limiting grooves.

[0008] Preferably, as the above technical solution, the end of the rotating rod is fixedly connected with a connecting plate. The other ends of the connecting plates on the rotating rods at both ends of the frame body are connected with a cover plate. The connecting mode between the connecting plate and the cover plate is a rotating connection. The cover plate is L-shaped and is used to press the photovoltaic panel body.

[0009] Preferably, as the above technical solution, a pressing plate is arranged on the inner side of the cover plate, and the pressing plate abuts on the surface of the photovoltaic panel body.

[0010] Preferably, as the above technical solution, an air cavity is formed in the cover plate. A piston is movably installed in the air cavity. An elastic member I is connected between the piston and the air cavity. A vertical part is arranged at the top of the frame body. A push plate is fixed at the top of the vertical part. The push plate penetrates through the cover plate and extends into the air cavity to abut against the piston. An air flow channel is also formed in the cover plate. An L-shaped airbag is installed on the inner side of the cover plate, and the air flow channel is connected with the airbag.

[0011] Preferably, as the above technical solution, a slope is formed on the side of the corner fitting that fits the partition plate. A T-shaped top plate is installed through the top of the frame body. The bottom of the top plate extends into the installation groove. The bottom of the top plate is an inclined surface and abuts against the slope.

[0012] Preferably, as the above technical solution, a support part is arranged on one side of the top of the frame body away from the vertical part.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, during assembly, first, two long sides and two short sides are arranged in a rectangular shape, and then corner connectors are installed at the four corners, with both ends of the corner connectors respectively abutting against the partitions inside the adjacent frame bodies. Then, the two long sides and two short sides are pushed towards each other, causing the corner connectors to move towards the rotating rods, thereby also inserting the rotating rods inside the frame bodies into the through holes on the corner connectors, and at the same time inserting the guiding blocks into the guiding grooves. As the corner connectors continue to move, since the guiding groove is a spiral groove, the guiding blocks drive the rotating rods to rotate. When the inclined surfaces at the ends of two adjacent frame bodies are in contact, the locking assembly locks the rotating rods to restrict their rotation. Since the guiding blocks are located inside the guiding grooves, if the rotating rods do not rotate, the positions of the guiding blocks remain unchanged all the time, thereby enabling the guiding blocks to restrict the corner connectors through the guiding grooves, and thus assembling the two long sides and two short sides together. This assembly method does not require tools, is simple to operate, has high assembly efficiency, and does not damage the frame bodies during the disassembly and assembly process; 2. In the present invention, since the solar photovoltaic panel may be affected by vibrations during use, due to the restricted rotation of the rotating rods, when the frame bodies are subjected to vibrations, the rotating rods will not rotate either. The guiding blocks on the rotating rods restrict the corner connectors, causing the positions of the corner connectors relative to two adjacent frame bodies to remain unchanged, thereby ensuring the stability of the connection between two adjacent frame bodies, and further enabling the two long sides and two short sides to always maintain a stable state after assembly, avoiding damage to the photovoltaic panel body caused by loosening at the connection; 3. In the present invention, through the cooperation of the ratchet and the ratchet teeth, the ratchet is stuck and can only rotate in one direction and cannot rotate in the reverse direction. Since the corner connectors cannot move further after the inclined surfaces at the ends of two adjacent frame bodies are in contact, the rotating rods cannot continue to rotate in one direction, thereby also preventing the ratchet from rotating in one direction. Since there is no driving source to rotate the rotating rods in the reverse direction and the ratchet cannot rotate in the reverse direction, the rotating rods remain stationary, and thus the corner connectors also remain stationary all the time. This installation method is not only fast and convenient, but also the position of the corner connectors relative to two adjacent frame bodies remains unchanged after installation, thereby ensuring the stability of the connection between two adjacent frame bodies, and further enabling the two long sides and two short sides to always maintain a stable state after assembly; 4. In the present invention, during the movement of the corner connectors towards the rotating rods, the limiting grooves on the corner connectors gradually approach the limiting blocks, and the limiting blocks finally get stuck in the limiting grooves, which can enhance the stability of the corner connectors after installation and prevent the corner connectors from shifting after installation; at the same time, if the frame bodies are pulled outwards when the assembly of the frame bodies is completed, on the one hand, the corner connectors are restricted by the rotating rods, and on the other hand, they are restricted by the limiting blocks and the limiting grooves, and the restriction of the limiting blocks and the limiting grooves is more firm than that of the rotating rods. This can effectively prevent the rotating rods from being squeezed and bent by the corner connectors when the frame bodies are pulled outwards, thereby ensuring the stability and strength of the corner connectors and the rotating rods after installation, and further enabling the two long sides and two short sides to always maintain a stable state after assembly, avoiding damage to the photovoltaic panel body caused by loosening at the connection; 5. In the present invention, the method of fixing the photovoltaic panel body by moving the cover plate downward and removing the A-side frame structure at the top of the frame body can effectively avoid dust accumulation and water accumulation at the edge position of the photovoltaic panel body, thereby preventing the reduction of the photoelectric conversion efficiency of the photovoltaic panel body. 6. In the present invention, during the process of the cover plate moving downward, the push plate on the vertical part enters the air chamber and slowly pushes the piston upward, so that the piston squeezes the air in the air chamber into the airbag through the air flow channel, causing the airbag to expand and abut against the surface of the photovoltaic panel body, so that the edge position of the photovoltaic panel body maintains a good sealing state after installation, effectively preventing water vapor from entering each functional layer of the photovoltaic panel body and causing damage to the photovoltaic panel body. At the same time, the airbag can buffer the photovoltaic panel body and prevent the photovoltaic panel body from shaking and squeezing the cover plate when being vibrated, resulting in damage to the photovoltaic panel body.

[0016] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0018] As Figures 1-7 shown, a flat, firm and easily installable aluminum profile frame for a solar photovoltaic panel includes a long side 2 and a short side 3. The long side 2 and the short side 3 are collectively referred to as the frame body 4. The two ends of the frame body 4 are inclined surfaces. The frame further includes: A corner fitting 5. A partition board 42 is arranged inside the frame body 4. The space between the partition board 42 and the end of the frame body 4 forms an installation groove 41. The two ends of the corner fitting 5 are respectively installed in the installation grooves 41 of the two frame bodies 4, and the end of the corner fitting 5 abuts against the partition board 42; A rotating rod 6. The rotating rod 6 is rotatably installed on the outer surface of the frame body 4. The rotating rod 6 extends into the installation groove 41. A through hole 51 is provided in the part of the corner fitting 5 located in the installation groove 41. The rotating rod 6 is sleeved in the through hole 51. A guide block 61 is arranged on the periphery of the rotating rod 6, and a spiral guide groove 511 is provided in the through hole 51. The guide block 61 is located in the guide groove 511; A locking assembly 8. A movable groove 43 is provided in the inner wall of the frame body 4. The locking assembly 8 is installed in the movable groove 43. The locking assembly 8 is connected to the rotating rod 6, and the locking assembly 8 is used to lock the rotating rod 6.

[0019] In actual application of this embodiment, first, two long sides 2 and two short sides 3 are arranged in a rectangular shape, and then corner brackets 5 are installed at the four corners, with both ends of the corner brackets 5 respectively abutted against the partitions 42 inside the adjacent frame bodies 4. Then, the two long sides 2 and the two short sides 3 are pushed to move towards each other, causing the corner brackets 5 to move towards the rotating rod 6, thereby also inserting the rotating rod 6 inside the frame body 4 into the through holes 51 on the corner brackets 5. At the same time, the guiding blocks 61 are inserted into the guiding grooves 511. The corner brackets 5 continue to move. Since the guiding groove 511 is a spiral groove, this causes the guiding block 61 to drive the rotating rod 6 to rotate. When the inclined surfaces at the ends of two adjacent frame bodies 4 are in contact, the locking assembly 8 locks the rotating rod 6 to restrict the rotation of the rotating rod 6. Since the guiding block 61 is located in the guiding groove 511, if the rotating rod 6 does not rotate, the position of the guiding block 61 remains unchanged all the time, thereby enabling the guiding block 61 to restrict the corner bracket 5 through the guiding groove 511, so that the two long sides 2 and the two short sides 3 are assembled together. This assembly method does not require tools, is simple to operate, has high assembly efficiency, and will not damage the frame body 4 during the disassembly and assembly process; Since the solar photovoltaic panel may be affected by vibrations during use, due to the restricted rotation of the rotating rod 6, when the frame body 4 is vibrated, the rotating rod 6 will not rotate either. The guiding block 61 on the rotating rod 6 restricts the corner bracket 5, so that the position of the corner bracket 5 relative to the two adjacent frame bodies 4 remains unchanged, thereby ensuring the stability of the connection between the two adjacent frame bodies 4, and further enabling the two long sides 2 and the two short sides 3 to always maintain a stable state after assembly, avoiding loosening at the connection and causing the photovoltaic panel body 1 to shake and be damaged.

[0020] Further, the locking assembly 8 includes a ratchet 81 and a ratchet tooth 82. A ratchet 81 is fixed on the outer periphery of the rotating rod 6. The ratchet 81 is located in the movable groove 43. A ratchet tooth 82 is also rotatably installed in the movable groove 43. The movable end of the ratchet tooth 82 abuts in the tooth groove of the ratchet 81. A second elastic member 821 is connected between one side of the ratchet tooth 82 and the movable groove 43. A dial 822 is arranged on one side of the ratchet tooth 82. A through groove 47 is formed on the surface of the frame body 4. The through groove 47 communicates with the movable groove 43. The dial 822 extends out of the frame body 4 from the through groove 47.

[0021] In one case of this embodiment, the second elastic member 821 can be a spring or other components that can elastically expand and contract.

[0022] In actual application of this embodiment, when the rotating rod 6 rotates, the ratchet wheel 81 also rotates accordingly. When the inclined surfaces at the ends of two adjacent frame bodies 4 are in contact, the assembly of the two frame bodies 4 is completed. At this time, the rotating rod 6 stops rotating, and the ratchet wheel 81 also stops rotating. At this time, due to the elasticity of the second elastic member 821, the ratchet teeth 82 are stuck in the tooth grooves of the ratchet wheel 81, so that the ratchet wheel 81 can only rotate in one direction and cannot rotate in the reverse direction. Since the corner fitting 5 cannot move further after the inclined surfaces at the ends of two adjacent frame bodies 4 are in contact, the rotating rod 6 cannot continue to rotate in one direction, so that the ratchet wheel 81 cannot rotate in one direction either. Since there is no driving source to rotate the rotating rod 6 in the reverse direction and the ratchet wheel 81 cannot rotate in the reverse direction, the rotating rod 6 remains stationary, and further the corner fitting 5 always remains stationary. This installation method is not only fast and convenient, but also the position of the corner fitting 5 remains unchanged relative to the positions of two adjacent frame bodies 4 after installation, thus ensuring the stability of the connection between two adjacent frame bodies 4, and further enabling the two long sides 2 and the two short sides 3 to always maintain a stable state after assembly; When disassembly is required, just move the dial 822 to move the ratchet teeth 82 out of the tooth grooves of the ratchet wheel 81, so that the ratchet wheel 81 can rotate, and thus the rotating rod 6 can rotate. In this way, the frame body 4 can be pulled outwards to slowly move the corner fitting 5 out of the rotating rod 6, thus completing the disassembly; during installation, just push the frame body 4 inwards, and during disassembly, just move the dial 822 and then pull the frame body 4 outwards. The disassembly and installation processes are convenient and fast, improving the disassembly and installation efficiency; The locking assembly 8 is composed of the ratchet wheel 81, the ratchet teeth 82 and the second elastic member 821. On the one hand, this structure has strong self-locking ability and can securely fix the rotating rod 6, effectively preventing the rotating rod 6 from rotating in the locked state; on the other hand, this structure has fewer components, is simple in structure, and has low processing precision requirements, which can reduce the manufacturing cost, and can be conveniently installed in the limited space inside the frame body 4.

[0023] As Figure 5 、 Figure 6 、 Figure 7 and Figure 9 shown, a number of limiting blocks 46 are arranged in the installation groove 41. The limiting blocks 46 are perpendicular to the corner fitting 5. A number of limiting grooves 52 are formed in the part of the corner fitting 5 located in the installation groove 41, and the limiting blocks 46 are stuck in the limiting grooves 52.

[0024] In actual application of this embodiment, during the process of the corner fitting 5 moving towards the rotating rod 6, the limiting grooves 52 on the corner fitting 5 gradually approach the limiting blocks 46, and finally the limiting blocks 46 are stuck in the limiting grooves 52, which can enhance the stability of the corner fitting 5 after installation and prevent the corner fitting 5 from shifting after installation; Meanwhile, if the frame body 4 is pulled outward when the assembly is completed, on the one hand, the angle code 5 is restricted by the rotating rod 6, and on the other hand, it is restricted by the limiting block 46 and the limiting groove 52. Moreover, the restriction of the limiting block 46 and the limiting groove 52 is firmer than that of the rotating rod 6. This can effectively prevent the rotating rod 6 from being squeezed and bent by the angle code 5 when the frame body 4 is pulled outward, thus ensuring the stability and strength of the angle code 5 and the rotating rod 6 after installation. Furthermore, the two long sides 2 and the two short sides 3 always maintain a stable state after assembly, avoiding loosening at the connection and causing damage to the photovoltaic panel body 1 due to shaking.

[0025] As Figure 2 , Figure 3 , Figure 4 and Figure 8 shown, a connecting plate 62 is fixedly connected to the end of the rotating rod 6. The other ends of the connecting plates 62 on the rotating rods 6 at both ends of the frame body 4 are connected to a cover plate 7. The connection mode between the connecting plate 62 and the cover plate 7 is a rotational connection. The cover plate 7 is L-shaped, and the cover plate 7 is used to press the photovoltaic panel body 1.

[0026] In actual application of this embodiment, during installation, when the rotating rod 6 rotates, the two rotating rods 6 at both ends of the frame body 4 rotate through the two connecting plates 62. Thus, the two connecting plates 62 drive the cover plate 7 to displace obliquely downward until the cover plate 7 presses on the surface of the photovoltaic panel body 1, thereby fixing the photovoltaic panel body 1. Here, the top of the frame body 4 is a border structure without an A surface. Since the traditional frame has an A surface, after the photovoltaic panel body 1 is installed, there is a gap between the A surface and the photovoltaic panel body 1. As a result, dust and water are likely to accumulate between the A surface and the photovoltaic panel body 1, causing part of the area of the photovoltaic panel body 1 to be blocked by dust, reducing the light absorption rate of the photovoltaic panel body 1 and resulting in a decrease in power generation. The accumulated dust can form an uneven water film, causing light refraction or reflection and further reducing the photoelectric conversion efficiency. Here, the method of fixing the photovoltaic panel body 1 by moving the cover plate 7 downward and removing the border structure with an A surface at the top of the frame body 4 can effectively prevent dust and water from accumulating at the edge position of the photovoltaic panel body 1, thus avoiding a reduction in the photoelectric conversion efficiency of the photovoltaic panel body 1.

[0027] Furthermore, a pressing plate 71 is provided inside the cover plate 7, and the pressing plate 71 abuts against the surface of the photovoltaic panel body 1.

[0028] Furthermore, an air cavity 73 is formed in the cover plate 7. A piston 74 is movably installed in the air cavity 73. An elastic member 75 is connected between the piston 74 and the air cavity 73. A vertical portion 44 is provided at the top of the frame body 4. A push plate 441 is fixed to the top of the vertical portion 44. The push plate 441 penetrates through the cover plate 7 and extends into the air cavity 73 to abut against the piston 74. An air flow passage 76 is also formed in the cover plate 7. An L-shaped airbag 72 is installed on the inner side of the cover plate 7. The air flow passage 76 is connected to the airbag 72.

[0029] It should be noted that pressing down the photovoltaic panel body 1 by the cover plate 7 may cause ineffective sealing at the edge of the photovoltaic panel body 1, resulting in easy entry of water vapor into each functional layer of the photovoltaic panel body 1, and further damaging the photovoltaic panel body 1. Therefore, relevant structures are proposed to solve the above problems.

[0030] In one case of this embodiment, the elastic member 75 can be a spring or other components that can elastically stretch.

[0031] In actual application of this embodiment, during the downward movement of the cover plate 7, the push plate 441 on the vertical portion 44 enters the air cavity 73 and slowly pushes the piston 74 to move upward. As a result, the piston 74 squeezes the air in the air cavity 73 into the airbag 72 through the air flow passage 76, causing the airbag 72 to expand and abut against the surface of the photovoltaic panel body 1. Thus, the edge position of the photovoltaic panel body 1 maintains a good sealing state after installation, effectively preventing water vapor from entering each functional layer of the photovoltaic panel body 1 and causing damage to the photovoltaic panel body 1. At the same time, the airbag 72 can buffer the photovoltaic panel body 1, avoiding damage to the photovoltaic panel body 1 caused by the shaking and squeezing of the cover plate 7 when the photovoltaic panel body 1 is vibrated. The pressing plate 71 is located outside the airbag 72. The pressing plate 71 serves two purposes. On the one hand, it abuts against the photovoltaic panel body 1 to ensure the stability of the photovoltaic panel body 1. On the other hand, the pressing plate 71 can protect the airbag 72, effectively preventing external sharp impurities from piercing the airbag 72, thus ensuring that the airbag 72 can normally protect the photovoltaic panel body 1.

[0032] As Figure 10 shown, a slope 53 is formed on one side of the angle code 5 that fits the partition plate 42. A T-shaped top plate 9 is installed through the top of the frame body 4. The bottom of the top plate 9 extends into the installation groove 41. The bottom of the top plate 9 is an inclined surface and abuts against the slope 53.

[0033] In actual application of this embodiment, during the movement of the angle code 5 towards the rotating rod 6, the slope 53 on the angle code 5 presses the top plate 9, causing the top plate 9 to move upward, thereby supporting the photovoltaic panel body 1. Cooperating with the cover plate 7 pressing down the photovoltaic panel body 1, the photovoltaic panel body 1 maintains a stable state after installation.

[0034] As Figure 4 and Figure 10As shown, a support portion 45 is provided on one side of the top of the frame body 4 away from the vertical portion 44.

[0035] In actual application of this embodiment, when the frame body 4 is deformed or the photovoltaic panel body 1 needs better protection, glue is applied between the cover plate 7 and the frame body 4 at this time, so that the photovoltaic panel body 1 is better sealed. At this time, the support portion 45 can effectively prevent the glue from overflowing, cooperate with the cover plate 7 to block other positions, so that the glue can fill the air between the cover plate 7, the photovoltaic panel body 1 and the frame body 4, making the photovoltaic panel body 1 have better sealing performance, effectively preventing the photovoltaic panel body 1 from being damaged, and at the same time can make up for the defects of the frame body 4 when it is damaged.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
