Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of photovoltaic modules, and particularly relates to a flat and firm solar photovoltaic panel aluminum profile frame. BACKGROUND

[0002] The solar photovoltaic panel aluminum profile frame is a component of a solar panel, usually made of aluminum alloy, used for protecting the edges of the solar panel and enhancing the structural strength thereof.

[0003] The existing frame is generally composed of two long frames and two short frames, and the frame assembly can be achieved in the following ways: first, glue is applied to the inner side of the frame, and the frame is clamped on the side of the photovoltaic panel, which is simple in operation but troublesome in subsequent disassembly; second, the opposite corners of the frame are fixed by using bolts and nuts, which is low in disassembly efficiency; third, a toothed corner code is used to form a fixed state by extruding the inner wall of the frame through interference fit of the corner code with the two frames, which is poor in stability and is prone to loosening at the connection, and the inner wall of the frame is easily damaged after disassembly, so that the frame cannot be reused; and fourth, the frame is installed by using a combination of a bolt and a corner code, which is low in disassembly efficiency. In summary, the above-mentioned assembly methods are low in efficiency and are prone to damage to the frame, so that the frame cannot be reused. SUMMARY

[0005] The object of the application can be achieved by the following technical scheme:

[0006] A flat and firm solar photovoltaic panel aluminum profile frame, comprising a long side and a short side, which are collectively referred to as a frame body, and the two ends of the frame body are inclined surfaces, and the frame further comprises:

[0007] A corner code, a partition plate is arranged in the frame body, a space between the partition plate and the end of the frame body forms a mounting groove, the two ends of the corner code are respectively mounted in the mounting grooves of the two frame bodies, and the end of the corner code abuts against the partition plate;

[0009] The inner wall of the frame body is provided with a movable groove, and a locking assembly is installed in the movable groove and connected with the rotating rod.

[0010] The locking assembly comprises a ratchet wheel and a ratchet tooth.

[0011] The installation groove is provided with a plurality of limiting blocks, the limiting blocks are perpendicular to the corner code, and the part of the corner code located in the installation groove is provided with a plurality of limiting grooves.

[0012] The end of the rotating rod is fixedly connected with a connecting plate, the other end of the connecting plate on the rotating rod at the two ends of the frame body is connected with a cover plate, the connecting plate and the cover plate are connected in a rotating mode, the cover plate is L-shaped, and the cover plate is used for pressing the photovoltaic plate body.

[0013] The inner side of the cover plate is provided with a pressing plate, and the pressing plate abuts against the surface of the photovoltaic plate body.

[0014] The cover plate is provided with an air cavity, a piston is movably installed in the air cavity, an elastic member one is connected between the piston and the air cavity, a vertical portion is arranged at the top of the frame body, a push plate is fixed at the top of the vertical portion, the push plate penetrates through the cover plate and extends into the air cavity and abuts against the piston, an air flow channel is further arranged in the cover plate, an L-shaped air bag is installed on the inner side of the cover plate, and the air flow channel is connected with the air bag.

[0015] The side, close to the partition, of the corner code is provided with an inclined slope, 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, and the bottom of the top plate is an inclined surface and abuts against the inclined slope.

[0016] The side, far from the vertical portion, of the top of the frame body is provided with a supporting portion.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] 1. In this invention, during assembly, the two long sides and two short sides are first arranged into a rectangle. Then, corner brackets are installed at the four corners, with the two ends of the corner brackets abutting against the partitions inside the adjacent frame bodies. Next, the two long sides and two short sides are pushed to move towards each other, causing the corner brackets to move towards the rotating rod. This allows the rotating rod inside the frame body to be inserted into the through hole on the corner bracket, while the guide block is inserted into the guide groove. The corner bracket continues to move. Since the guide groove is a spiral groove, the guide block drives the rotating rod to rotate. When the inclined surfaces at the ends of two adjacent frame bodies are in contact, the locking component locks the rotating rod, restricting its rotation. Since the guide block is located in the guide groove, if the rotating rod does not rotate, the position of the guide block remains unchanged. This allows the guide block to restrict the corner bracket through the guide groove, 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 body during assembly and disassembly.

[0019] 2. In this invention, since the solar photovoltaic panel may be affected by vibration during use, the rotating rod is restricted from rotating. When the frame body is vibrated, the rotating rod will not rotate. The guide block on the rotating rod restricts the corner bracket, so that the position of the corner bracket relative to the two adjacent frame bodies remains unchanged, thereby ensuring the stability of the connection between the two adjacent frame bodies. This ensures that the two long sides and two short sides remain stable after assembly, and avoids the photovoltaic panel body from shaking and being damaged due to loosening at the connection.

[0020] 3. In this invention, the ratchet is locked by the ratchet and the ratchet teeth. The ratchet can only rotate forward and cannot rotate backward. Since the corner bracket cannot continue to move after the inclined surfaces at the ends of the two adjacent frame bodies are attached, the rotating rod cannot continue to rotate forward, and thus the ratchet cannot rotate forward either. Since there is no driving source to make the rotating rod rotate backward, and the ratchet cannot rotate backward, the rotating rod remains stationary, and thus the corner bracket remains stationary. This installation method is not only quick and convenient, but also ensures that the position of the corner bracket relative to the position of the two adjacent frame bodies remains unchanged after installation, thereby ensuring the stability of the connection between the two adjacent frame bodies, and thus ensuring that the two long sides and two short sides remain stable after assembly.

[0021] 4. In this invention, as the corner bracket moves toward the rotating rod, the limiting groove on the corner bracket gradually approaches the limiting block, and the limiting block eventually gets stuck in the limiting groove. This enhances the stability of the corner bracket after installation and prevents displacement. Simultaneously, if the frame body is pulled outwards while assembled, the corner bracket is restrained by both the rotating rod and the limiting block and limiting groove. Furthermore, the restraint by the limiting block and limiting groove is more robust than that by the rotating rod. This effectively prevents the rotating rod from bending and deforming due to pressure from the corner bracket when the frame body is pulled outwards, thus ensuring the stability and strength of the corner bracket and rotating rod after installation. This ensures that the two long sides and two short sides remain stable after assembly, preventing loose connections that could cause the photovoltaic panel to shake and be damaged.

[0022] 5. In this invention, the method of fixing the photovoltaic panel body by moving the cover plate down and removing the A-side frame structure at the top of the frame body can effectively prevent dust and water accumulation at the edge of the photovoltaic panel body, thereby preventing the reduction of the photoelectric conversion efficiency of the photovoltaic panel body.

[0023] 6. In this invention, during the downward movement of the cover plate, the push plate on the vertical part enters the air cavity and slowly pushes the piston upward, thereby causing the piston to squeeze the air in the air cavity into the airbag through the airflow channel. This causes the airbag to expand and come into contact with the surface of the photovoltaic panel body, thus ensuring that the photovoltaic panel body maintains a good sealing state at the edge position after installation. This effectively prevents moisture from entering the various functional layers 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 subjected to vibration, thus preventing damage to the photovoltaic panel body.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0037] The specific implementation of the present application is described in detail below in combination with specific examples.

[0038] As Figures 1-7 shown, a flat and firm solar photovoltaic panel aluminum profile frame for installation, including long side 2 and short side 3, long side 2 and short side 3 are collectively referred to as frame body 4, both ends of frame body 4 are inclined surface, the frame further comprises:

[0039] corner code 5, frame body 4 is provided with partition 42, the space between partition 42 and the end of frame body 4 forms mounting groove 41, both ends of corner code 5 are installed in mounting groove 41 of two frame bodies 4, respectively, the end of corner code 5 abuts against partition 42;

[0040] rotating rod 6, the outer surface of frame body 4 is rotatably installed with rotating rod 6, rotating rod 6 extends into mounting groove 41, the part of corner code 5 located in mounting groove 41 is provided with through hole 51, rotating rod 6 is sleeved in through hole 51, rotating rod 6 is provided with guide block 61 around, helical guide groove 511 is formed in through hole 51, guide block 61 is located in guide groove 511;

[0041] The locking assembly 8 is arranged in the movable groove 43 in the inner wall of the frame body 4, and is connected with the rotating rod 6.

[0042] In actual application, first, the two long sides 2 and the two short sides 3 are arranged into a rectangular shape, and then the corner code 5 is installed at the four corners, so that the two ends of the corner code 5 are respectively abutted against the partition plates 42 in the adjacent frame bodies 4. Then, the two long sides 2 and the two short sides 3 are pushed to move towards each other, so that the corner code 5 moves towards the rotating rod 6, and the rotating rod 6 in the frame body 4 is inserted into the through hole 51 in the corner code 5, and the guide block 61 is inserted into the guide groove 511. The corner code 5 continues to move, and since the guide groove 511 is a spiral groove, the guide block 61 drives the rotating rod 6 to rotate. When the inclined surfaces at the ends of the adjacent two frame bodies 4 are abutted, the locking assembly 8 locks the rotating rod 6 to limit the rotation of the rotating rod 6. Since the guide block 61 is located in the guide groove 511, if the rotating rod 6 does not rotate, the position of the guide block 61 remains unchanged, so that the guide block 61 limits the corner code 5 through the guide groove 511, so that the two long sides 2 and the two short sides 3 are assembled together. This assembly method does not need to use tools, is simple to operate, and has high assembly efficiency, and the frame body 4 is not damaged in the disassembly process.

[0043] Since the solar photovoltaic panel may be affected by vibration in use, since the rotating rod 6 is limited to rotate, when the frame body 4 is vibrated, the rotating rod 6 also does not rotate. The guide block 61 on the rotating rod 6 limits the corner code 5, so that the position of the corner code 5 relative to the adjacent two frame bodies 4 remains unchanged, thereby ensuring the stability of the connection of the adjacent two frame bodies 4, and further ensuring that the two long sides 2 and the two short sides 3 always remain in a stable state after assembly, avoiding loosening of the connection to cause the photovoltaic panel body 1 to shake and be damaged.

[0044] Further, the locking assembly 8 comprises a ratchet wheel 81 and a ratchet tooth 82. The ratchet wheel 81 is fixed to the periphery of the rotating rod 6 and located in the movable groove 43. The ratchet tooth 82 is also rotatably arranged in the movable groove 43. The movable end of the ratchet tooth 82 abuts against the tooth groove of the ratchet wheel 81. The elastic member two 821 is connected between one side of the ratchet tooth 82 and the movable groove 43. The ratchet tooth 82 is provided with a push piece 822. The through groove 47 is arranged on the surface of the frame body 4 and communicates with the movable groove 43. The push piece 822 extends out of the frame body 4 from the through groove 47.

[0045] In one case of the embodiment, the elastic member two 821 can be a spring, or other components capable of elastic expansion and contraction.

[0046] The embodiment is applied in practice. When the rotating rod 6 rotates, the ratchet wheel 81 also rotates. When the inclined surfaces of the ends of the two adjacent frame bodies 4 are attached, the two frame bodies 4 are assembled. At this time, the rotating rod 6 does not rotate, and the ratchet wheel 81 also does not rotate. At this time, the ratchet wheel 81 is clamped in the tooth groove of the ratchet wheel 81 due to the elasticity of the elastic member two 821. Thus, the ratchet wheel 81 can only rotate forward and cannot rotate backward. Since the corner brace 5 cannot continue to move after the inclined surfaces of the ends of the two adjacent frame bodies 4 are attached, the rotating rod 6 cannot continue to rotate forward, so that the ratchet wheel 81 also cannot rotate forward. Since there is no driving source to rotate the rotating rod 6 backward, and the ratchet wheel 81 cannot rotate backward, the rotating rod 6 remains stationary, and the corner brace 5 also remains stationary. This installation method is not only fast and convenient, but also ensures that the position of the corner brace 5 relative to the positions of the two adjacent frame bodies 4 remains unchanged after installation, thereby ensuring the stability of the connection between the two adjacent frame bodies 4, and further ensuring that the two long sides 2 and the two short sides 3 remain in a stable state after assembly.

[0047] When disassembly is required, the wobble piece 822 is only needed to be waved to move the ratchet wheel 81 out of the tooth groove 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 outward to slowly move the corner brace 5 out of the rotating rod 6, thereby completing the disassembly. During installation, the frame body 4 only needs to be pushed inward. During disassembly, the frame body 4 only needs to be pulled outward after the wobble piece 822 is waved. The disassembly process is convenient and fast, and the disassembly efficiency is improved.

[0048] The locking assembly 8 is composed of the ratchet wheel 81, the ratchet wheel 81, and the elastic member two 821. On the one hand, this structure has strong self-locking ability and can safely fix the rotating rod 6. In the locked state, the rotating rod 6 can be effectively prevented from rotating. On the other hand, this structure has fewer components, a simple structure, and low machining precision requirements, which can reduce manufacturing costs and facilitate installation in the limited space in the frame body 4.

[0049] As shown in Figure 5 , Figure 6 , Figure 7 and Figure 9 , a plurality of limiting blocks 46 are arranged in the installation groove 41. The limiting blocks 46 are perpendicular to the corner brace 5. The portion of the corner brace 5 located in the installation groove 41 is provided with a plurality of limiting grooves 52. The limiting blocks 46 are clamped in the limiting grooves 52.

[0050] In practical application, during the movement of the corner brace 5 towards the rotating rod 6, the limiting grooves 52 on the corner brace 5 gradually approach the limiting blocks 46. The limiting blocks 46 are finally clamped in the limiting grooves 52. In this way, the stability of the corner brace 5 after installation can be improved, and displacement of the corner brace 5 after installation can be avoided.

[0051] Meanwhile, if the frame body 4 is pulled outward in the assembled state, the corner code 5 is limited by the rotating rod 6 on one hand, and by the limiting block 46 and the limiting groove 52 on the other hand, and the limiting of the limiting block 46 and the limiting groove 52 is more firm than the limiting of the rotating rod 6, so that the bending deformation of the rotating rod 6 caused by the extrusion of the corner code 5 when the frame body 4 is pulled outward can be effectively avoided, thereby ensuring the stability and strength of the corner code 5 and the rotating rod 6 after installation, and further ensuring that the two long edges 2 and the two short edges 3 always remain in a stable state after assembly, avoiding loosening of the connection to cause shaking and damage of the photovoltaic panel body 1.

[0052] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 8 , the end of the rotating rod 6 is fixedly connected with a connecting plate 62, and the other end of the connecting plate 62 on the rotating rod 6 at the two ends of the frame body 4 is connected with a cover plate 7, and the connecting plate 62 and the cover plate 7 are connected in a rotating manner, and the cover plate 7 is L-shaped, and the cover plate 7 is used to press the photovoltaic panel body 1.

[0053] In actual application, when the rotating rod 6 is rotated during installation, the two rotating rods 6 at the two ends of the frame body 4 are rotated through the two connecting plates 62, so that the two connecting plates 62 drive the cover plate 7 to move obliquely downward until the cover plate 7 is pressed on the surface of the photovoltaic panel body 1, so that the photovoltaic panel body 1 is fixed;

[0054] Here, the top of the frame body 4 is an A-face-free frame structure. Since the traditional frame has an A-face, there is a gap between the A-face and the photovoltaic panel body 1 after the photovoltaic panel body 1 is installed, which causes dust and water to accumulate between the A-face and the photovoltaic panel body 1, thereby causing some areas of the photovoltaic panel body 1 to be blocked by dust, thereby reducing the light absorption rate of the photovoltaic panel body 1 and reducing the power generation capacity. The accumulated dust can form an uneven water film, causing light refraction or reflection and further reducing the photoelectric conversion efficiency. Here, the cover plate 7 is used to fix the photovoltaic panel body 1 by moving downward, and the A-face frame structure at the top of the frame body 4 is removed, which can effectively avoid the accumulation of dust and water at the edge of the photovoltaic panel body 1, thereby avoiding the reduction of the photoelectric conversion efficiency of the photovoltaic panel body 1.

[0055] Further, the inside of the cover plate 7 is provided with a pressing plate 71 abutting against the surface of the photovoltaic panel body 1.

[0056] Further, the cover plate 7 is provided with an air cavity 73, and a piston 74 is movably arranged in the air cavity 73, and an elastic member 75 is connected between the piston 74 and the air cavity 73. The top of the frame body 4 is provided with a vertical portion 44, and the top of the vertical portion 44 is fixed with a push plate 441 which penetrates through the cover plate 7 and extends into the air cavity 73 and abuts against the piston 74. The cover plate 7 is further provided with an air flow channel 76, and an L-shaped air bag 72 is arranged on the inner side of the cover plate 7, and the air flow channel 76 is connected with the air bag 72.

[0057] It should be noted that the cover plate 7 is pressed downward to press the photovoltaic panel body 1, so that the edge of the photovoltaic panel body 1 cannot be effectively sealed, and thus water vapor is easily introduced into each functional layer of the photovoltaic panel body 1, and the photovoltaic panel body 1 is damaged. Therefore, the related structure is proposed to solve the above problem.

[0058] In one case of the embodiment, the elastic member 75 can be a spring, or other components capable of elastic expansion and contraction.

[0059] In actual application, in the process of moving the cover plate 7 downward, the push plate 441 on the vertical portion 44 enters the air cavity 73 and slowly pushes the piston 74 to move upward, so that the piston 74 pushes the air in the air cavity 73 into the air bag 72 through the air flow channel 76, so that the air bag 72 expands and abuts against the surface of the photovoltaic panel body 1, so that the edge of the photovoltaic panel body 1 is kept in a good sealing state after installation, effectively avoiding the introduction of water vapor into each functional layer of the photovoltaic panel body 1 to cause damage to the photovoltaic panel body 1. At the same time, the air bag 72 can buffer the photovoltaic panel body 1, avoiding the photovoltaic panel body 1 from shaking and pressing the cover plate 7 to cause damage to the photovoltaic panel body 1 when the photovoltaic panel body 1 is subjected to vibration.

[0060] The pressing plate 71 is located on the outer side of the air bag 72. The pressing plate 71 has the functions of abutting against the photovoltaic panel body 1 to ensure the stability of the photovoltaic panel body 1, and protecting the air bag 72 to effectively avoid that the air bag 72 is pierced by sharp impurities from the outside, so as to ensure that the air bag 72 can normally protect the photovoltaic panel body 1.

[0061] As shown in Figure 10 The corner code 5 is provided with a slope 53 on one side of the partition plate 42, and a T-shaped top plate 9 is arranged on the top of the frame body 4, the bottom of the top plate 9 extends into the installation slot 41, and the bottom of the top plate 9 is an inclined surface and abuts against the slope 53.

[0062] In actual application, in the process of moving the corner code 5 towards the rotating rod 6, the slope 53 on the corner code 5 presses the top plate 9, so that the top plate 9 moves upward and supports the photovoltaic panel body 1, and the cover plate 7 presses the photovoltaic panel body 1 downward, so that the photovoltaic panel body 1 is kept in a stable state after installation.

[0063] As shown in Figure 4 andFigure 10 As shown, the top of the frame body 4 is provided with a support part 45 away from one side of the vertical part 44.

[0064] In actual application, when the frame body 4 is deformed or the photovoltaic panel body 1 needs better protection, the glue is injected between the cover plate 7 and the frame body 4, so that the photovoltaic panel body 1 is better sealed. At this time, the support part 45 can effectively prevent the glue from overflowing, and 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, so that the photovoltaic panel body 1 has better sealing performance, effectively avoids damage to the photovoltaic panel body 1, and at the same time can make up for the defects of the frame body 4 when damaged.

[0065] The basic principles, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
