Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panels, and more specifically, to a solar photovoltaic panel frame. Background Art

[0002] A solar panel is a device that absorbs sunlight and directly or indirectly converts solar radiant energy into electrical energy through the photovoltaic effect or the photochemical effect. Most solar panels are mainly made of "silicon", but due to the high production cost, its widespread use still has certain limitations.

[0003] Chinese Patent No. CN111934603B discloses a highly secure solar photovoltaic panel frame for high places. By adjusting the adjusting bolts at the two hinge joints, the angles between the mounting base and the receiving rod and between the frame and the telescopic rod can be conveniently adjusted, facilitating the convenient adjustment of the angle of the entire frame. The buffer springs between the telescopic rod and the receiving rod and the adjusting springs provided between the slider and the adjusting chamber can both play a certain buffering role, buffering the pressure caused by factors such as flying birds landing on the frame or wind force, achieving multi-directional pressure dispersion, preventing the frame from deforming or breaking, and having relatively high security.

[0004] Although this highly secure solar photovoltaic panel frame for high places can prevent the frame from deforming or breaking and has relatively high security, like the traditional frame installation method, it uses bolts for fixation. Currently, common solar photovoltaic panels usually come with a single metal frame, which is directly fixed to the mounting bracket through connectors such as bolts during installation. This design, while providing basic structural support, also has some deficiencies. During installation, multiple sets of connectors are required to ensure that the frame is firmly fixed to the bracket, which increases the complexity and time cost of installation. In addition, when disassembly or maintenance is required, this process is also cumbersome and inconvenient because each connection point needs to be processed one by one. Such an installation method is not only inefficient but also poses challenges in long-term maintenance, especially when it is necessary to quickly replace or repair individual components. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a solar photovoltaic panel frame that can achieve convenient installation.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A solar photovoltaic panel frame includes a frame body. An inner cavity is formed inside the frame body. At the four corners of the lower side of the frame body, there are first support legs respectively. The lower end of each first support leg is hinged with a support member. The lower end of the support member is fixedly installed with a fixing plate. Multiple fixing holes are formed on the upper end surface of the fixing plate. A first slot is formed at the upper end of the first support leg. A folding mechanism is arranged inside the inner cavity. The folding mechanism includes adjusting and fixing members at the four corners inside the inner cavity. The adjusting and fixing member includes fixing members fixedly installed on both inner side walls of the inner cavity. A fixing tube is fixedly installed between the two fixing members. The outer surface of the fixing tube is rotatably connected with an outer shell. The outer surface of the outer shell is fixedly installed with a second support leg. A notch is formed on the lower end surface of the frame corresponding to the second support leg. A handle is fixedly installed on the lower end surface of the second support leg. The adjusting and fixing member further includes a first baffle and a second baffle arranged inside the outer shell. The first baffle is fixedly connected with the fixing tube. The second baffle is fixedly connected with the inner wall of the outer shell.

[0008] An airbag is fixedly installed between the first baffle and the second baffle. An air inlet is communicated with the outer surface of the second baffle and the airbag. An air outlet pipe is communicated between the airbag and the fixing tube.

[0009] One end of the fixing tube is slidably connected with a piston rod. One end of the piston rod is fixedly installed with a transmission plate. A plug rod is eccentrically installed on the front end surface of the transmission plate. Multiple second slots are formed on the inner wall of the inner cavity corresponding to the plug rod. A limiting column is slidably connected to the outer edge of the front end surface of the transmission plate. The limiting column is fixedly connected with the outer shell.

[0010] Multiple second slots are dispersedly arranged in a ring around the fixing tube. Buffer grooves are formed on the inner wall of the inner cavity corresponding to the multiple second slots. The depths of the multiple second slots increase gradually in sequence. The depths of the buffer grooves also increase gradually in sequence.

[0011] The folding mechanism further includes an unlocking and retracting member arranged inside the fixing tube. The unlocking and retracting member includes an air outlet pipe fixedly installed at the right end of the piston rod. The air outlet pipe is arranged inside the fixing tube. A transmission shaft is arranged inside the air outlet pipe.

[0012] A cavity is formed inside the transmission shaft. A second communication groove is formed on the outer surface of the transmission shaft. A first communication groove is formed on the outer surface of the air outlet pipe.

[0013] A button is arranged on one side of the frame body. One end of the button extends into the inner cavity and is fixedly connected with the transmission shaft. A first spring is fixedly installed between the button and the transmission plate. The second support leg is inserted into the first slot on the first support leg.

[0014] The folding mechanism further includes an auxiliary support group arranged on the upper side of the second support leg. The auxiliary support group includes an extrusion block fixedly installed on the outer surface of a fixed tube. The extrusion block is arranged inside a housing. A cavity is formed inside the second support leg, and the cavity communicates with the housing.

[0015] A slide plate is slidably connected inside the cavity. A slide rod is fixedly installed on the left end surface of the slide plate. The slide rod extends into the housing and is in close contact with the extrusion block. A second spring is fixedly installed between the slide rod and the inner wall of the cavity.

[0016] A transmission rod is fixedly installed on the right end surface of the slide plate. A limiting cavity is formed inside the second support leg. A shape memory alloy is slidably connected inside the limiting cavity. One end of the shape memory alloy extends into the inner cavity and is fixedly connected to the inside of the inner cavity. The other end of the shape memory alloy extends into the cavity and is fixedly connected to the transmission rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) By setting the folding mechanism in this solution, the support component is combined with the frame. When installation is required, the support component can be pulled out for free installation, and the deflection angle of the support component can be adjusted according to actual needs, increasing the practicability of the device.

[0019] (2) By setting the auxiliary support group in this solution, the support strength for the photovoltaic panel frame is enhanced, the load is effectively dispersed, and the stability of the overall structure is improved. This method not only avoids the deformation of the frame caused by uneven load but also extends the service life of the photovoltaic panel. By optimizing the support design, the maintenance frequency and cost are reduced, and at the same time, the installation and disassembly processes are simplified, improving the construction efficiency. In this way, both the stable operation of the photovoltaic system can be ensured and the long-term maintenance cost can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 9, a solar photovoltaic panel frame, including a frame body 1. An inner cavity 2 is provided inside the frame body 1. Support legs one 3 are provided at the four corners of the lower side of the frame body 1. The lower end of the support leg one 3 is hinged with a support member 4. The lower end of the support member 4 is fixedly installed with a fixing plate 5. Multiple fixing holes 6 are provided on the upper end surface of the fixing plate 5. A slot one 7 is provided at the upper end of the support leg one 3. A folding mechanism is provided inside the inner cavity 2. The folding mechanism includes adjusting and fixing members arranged at the four corners inside the inner cavity 2. The adjusting and fixing member includes fixing members 8 fixedly installed on both inner walls of the inner cavity 2. A fixing tube 9 is fixedly installed between the two fixing members 8. The outer surface of the fixing tube 9 is rotatably connected with an outer shell 10. A support leg two 11 is fixedly installed on the outer surface of the outer shell 10. A notch 12 is provided on the lower end surface of the frame corresponding to the support leg two 11. A handle 13 is fixedly installed on the lower end surface of the support leg two 11. The adjusting and fixing member further includes a baffle one 14 and a baffle two 15 arranged inside the outer shell 10. The baffle one 14 is fixedly connected with the fixing tube 9. The baffle two 15 is fixedly connected with the inner wall of the outer shell 10.

[0033] An airbag 16 is fixedly installed between the baffle one 14 and the baffle two 15. An air inlet 17 is provided on the outer surface of the baffle two 15 and is communicated with the airbag 16. An air outlet pipe 18 is provided between the airbag 16 and the fixing tube 9 and is communicated therewith.

[0034] One end of the fixing tube 9 is slidably connected with a piston column 19. One end of the piston column 19 is fixedly installed with a transmission plate 20. A plug rod 22 is eccentrically installed on the front end surface of the transmission plate 20. Multiple slot two 23 are provided on the inner wall of the inner cavity 2 corresponding to the plug rod 22. A limiting column 21 is slidably connected to the outer edge of the front end surface of the transmission plate 20. The limiting column 21 is fixedly connected with the outer shell 10.

[0035] Multiple slot two 23 are arranged in a ring and are dispersed around the fixing tube 9. A buffer groove 24 is provided on the inner wall of the inner cavity 2 corresponding to the multiple slot two 23. The depths of the multiple slot two 23 increase gradually step by step, and the depth of the buffer groove 24 also increases gradually step by step.

[0036] When the frame needs to be installed, first fix and install the first support leg 3, the support member 4 and the fixed plate 5 at the predetermined positions. The support member 4 is hinged to the first support leg 3, and the angle between the support member 4 and the first support leg 3 can be adjusted according to the usage situation. Subsequently, manually hold the handle 13 on the second support leg 11 and pull out the second support leg 11 from the inside of the notch 12. The second support leg 11 deflects around the fixed tube 9. While the second support leg 11 deflects, it drives the housing 10 to deflect synchronously. The baffle two 15 fixedly installed on the inner wall of the housing 10 deflects synchronously. There is an airbag 16 fixedly installed between the baffle one 14 and the baffle two 15. Therefore, when the baffle two 15 deflects, it squeezes the airbag 16, and the gas inside the airbag 16 enters the fixed tube 9 through the one-way output valve opened inside the air outlet pipe 18, thereby pushing out the piston column 19. The limit column 21 fixedly installed on the housing 10 is slidably connected to the transmission plate 20. Therefore, the transmission plate 20 drives the insertion rod 22 to deflect synchronously. At the same time, the transmission plate 20 at one end of the piston column 19 drives the insertion rod 22 to insert into the corresponding slot two 23 under the action of the piston column 19, thereby locking the second support leg 11. Different deflection angles can be selected according to different terrains to insert into different slot two 23s, and different slot two 23s are arranged in a stepped ring shape and decrease.

[0037] The folding mechanism further includes an unlocking and retracting member arranged inside the fixed tube 9. The unlocking and retracting member includes an air release pipe 39 fixedly installed at the right end of the piston column 19. The air release pipe 39 is arranged inside the fixed tube 9, and a transmission shaft 25 is arranged inside the air release pipe 39.

[0038] A cavity 26 is opened inside the transmission shaft 25, a second communication groove 28 is opened on the outer surface of the transmission shaft 25, and a first communication groove 27 is opened on the outer surface of the air release pipe 39.

[0039] One side of the frame body 1 is provided with a button 29. One end of the button 29 extends into the interior of the inner cavity 2 and is fixedly connected to the transmission shaft 25. A first spring 30 is fixedly installed between the button 29 and the transmission plate 20.

[0040] When it is necessary to release the fixation, by pressing the button 29, the transmission shaft 25 slides inside the air release pipe 39, so that the first communication groove 27 communicates with the second communication groove 28, and then the gas inside the fixed tube 9 enters the interior of the cavity 26 through the first communication groove 27 and the second communication groove 28 and is discharged from the device, thereby retracting the piston column 19 into the fixed tube 9, and the limit on the second support leg 11 can be released.

[0041] The folding mechanism further includes an auxiliary support group arranged on the upper side of the second support leg 11. The auxiliary support group includes an extrusion block 31 fixedly installed on the outer surface of the fixed tube 9. The extrusion block 31 is arranged inside the housing 10. A cavity 36 is opened inside the second support leg 11, and the cavity 36 communicates with the housing 10.

[0042] A slide plate 32 is slidably connected inside the cavity 36. A slide rod 33 is fixedly installed on the left end face of the slide plate 32. The slide rod 33 extends into the interior of the housing 10 and is in close contact with the extrusion block 31. A second spring 35 is fixedly installed between the slide rod 33 and the inner wall of the cavity 36.

[0043] A transmission rod 34 is fixedly installed on the right end face of the slide plate 32. A limiting cavity 38 is formed inside the second support leg 11. A shape memory alloy 37 is slidably connected inside the limiting cavity 38. One end of the shape memory alloy 37 extends into the interior of the inner cavity 2 and is fixedly connected to the interior of the inner cavity 2. The other end of the shape memory alloy 37 extends into the interior of the cavity 26 and is fixedly connected to the transmission rod 34.

[0044] When the second support leg 11 deflects, it synchronously drives the components inside the cavity 36 to deflect. The slide rod 33 inside the cavity 36 is in close contact with the extrusion block 31. Therefore, as the deflection angle of the second support leg 11 gradually increases, the sliding depth of the slide rod 33 under the action of the extrusion block 31 gradually increases. The slide rod 33 descends and then squeezes the shape memory alloy 37, causing the shape memory alloy 37 to extend out of the limiting cavity 38. The length of the shape memory alloy 37 extending out is different according to the rotation angle. The shape memory alloy 37 then provides auxiliary support for the second support leg 11. After the adjustment is completed, insert the second support leg 11 into the first slot 7 on the first support leg 3 and fix it with bolts.

[0045] Common solar photovoltaic panels currently usually come with a single metal frame, which is directly fixed to the mounting bracket through bolts and other connecting parts during installation. Although this design provides basic structural support, there are also some deficiencies. During the installation process, multiple sets of connecting parts are required to ensure that the frame is firmly fixed to the bracket, which increases the complexity and time cost of installation. In addition, when disassembly or maintenance is needed, this process is also cumbersome and inconvenient because each connection point needs to be processed one by one. Such an installation method is not only inefficient but also poses challenges in long-term maintenance, especially when it is necessary to quickly replace or repair individual components.

[0046] In this solution, by setting up a folding mechanism, the support components and the frame are combined with each other. When installation is required, the support components can be pulled out for free installation, and the deflection angle of the support components can be adjusted according to actual needs, increasing the practicality of the device;

[0047] At the same time, this solution also sets up an auxiliary support group to enhance the support force for the frame of the photovoltaic panel, effectively disperse the load and improve the stability of the overall structure. This method not only avoids the deformation of the frame caused by uneven load but also extends the service life of the photovoltaic panel. By optimizing the support design, the maintenance frequency and cost are reduced, while the installation and disassembly processes are simplified, improving the construction efficiency. This can not only ensure the stable operation of the photovoltaic system but also reduce the long-term maintenance cost.

[0048] Usage method: When border installation is required, first fixedly install the first support leg 3, the support member 4, and the fixing plate 5 at the predetermined positions. The support member 4 is hinged to the first support leg 3, and the angle between the support member 4 and the first support leg 3 can be adjusted according to the usage situation. Subsequently, manually hold the handle 13 on the second support leg 11 and pull out the second support leg 11 from inside the notch 12. The second support leg 11 deflects around the fixed tube 9. While the second support leg 11 deflects, it drives the housing 10 to deflect synchronously. The baffle two 15 fixedly installed on the inner wall of the housing 10 deflects synchronously. An airbag 16 is fixedly installed between the baffle one 14 and the baffle two 15. Therefore, when the baffle two 15 deflects, it squeezes the airbag 16, causing the gas inside the airbag 16 to enter the fixed tube 9 through the one-way output valve opened inside the air outlet pipe 18, thereby pushing out the piston column 19. The limit post 21 fixedly installed on the housing 10 is slidably connected to the transmission plate 20. Therefore, the transmission plate 20 synchronously drives the insertion rod 22 to deflect. At the same time, the transmission plate 20 at one end of the piston column 19 drives the insertion rod 22 to insert into the corresponding second slot 23 under the action of the piston column 19, thereby locking the second support leg 11. Different deflection angles can be selected according to different terrains to insert into different second slots 23. The different second slots 23 are arranged in a stepped circular shape and decrease;

[0049] The deflection of the second support leg 11 synchronously drives the components inside the cavity 36 to deflect. The sliding rod 33 inside the cavity 36 is in close contact with the extrusion block 31. Therefore, as the deflection angle of the second support leg 11 gradually increases, the depth of the sliding rod 33 sliding down under the action of the extrusion block 31 gradually increases. The sliding rod 33 descends and then squeezes the shape memory alloy 37, causing the shape memory alloy 37 to extend out of the limit cavity 38. The length of the shape memory alloy 37 extending out is different according to the rotation angle. The shape memory alloy 37 then provides auxiliary support for the second support leg 11. After the adjustment is completed, insert the second support leg 11 into the first slot 7 on the first support leg 3 and fix it with bolts;

[0050] When it is necessary to release the fixation, press the button 29 to make the transmission shaft 25 slide inside the air release pipe 39, so that the first communication groove 27 and the second communication groove 28 are interconnected. Then, the gas inside the fixed tube 9 enters the inside of the cavity 26 through the first communication groove 27 and the second communication groove 28 and is discharged from the device. Thereby, the piston column 19 retracts into the fixed tube 9, and the limit on the second support leg 11 can be released.

[0051] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical scheme and its improvement concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
