Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and more specifically, to a convenient assembly-type photovoltaic module fixing device. Background Technology

[0002] A photovoltaic (PV) module is a power generation device that uses semiconductor materials (such as silicon) to convert light energy into direct current (DC). Its core principle is based on the photovoltaic effect, achieving stable power generation through a solid-state structure with no moving parts. It is suitable for powering small electronic devices, building surface integration, and grid-connected power systems. PV modules require a fixing device for placement.

[0003] Traditional fixed installation devices are mostly rigid frame structures, which are cumbersome to assemble and require a large number of bolts. This not only consumes manpower and time but also requires highly skilled installers, making them unsuitable for the rapid construction needs of large-scale photovoltaic power plants. Furthermore, this rigid structure cannot be folded, taking up a lot of space during transportation, increasing transportation costs, and requiring large storage areas, causing inconvenience to logistics and warehousing. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a convenient assembled photovoltaic module fixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient assembly-type photovoltaic module fixing device, comprising two horizontal bars, with folding rods symmetrically and rotatably connected to both ends of the horizontal bars. A first connecting plate is rotatably connected to the opposite sides of the two folding rods on the same side. During transportation and storage, the folding rods can be folded towards the horizontal bars, significantly reducing the device volume. In use, the folding rods are unfolded to form a stable frame structure, providing a support frame for the photovoltaic module. The first connecting plate connects the two folding rods on the same side into a whole, enhancing the connection strength between the folding rods and preventing them from shaking or deforming during use, thus ensuring the stability of the frame structure. Support slots are provided at the top of both the horizontal bars and the folding rods. These slots accommodate the edges of the photovoltaic module, providing initial positioning and lateral constraint to prevent the photovoltaic module from sliding left and right on the frame structure. A rubber strip is fixedly connected to the top of the inner cavity of the support slot to further fix the photovoltaic module and prevent it from shaking up and down. Fixing blocks are symmetrically fixedly connected to both ends of one side of one of the horizontal bars.

[0006] A rotating block is provided on one side of the fixed block, and a first rotating connecting block is fixedly connected to one side of the rotating block. The rotating block is rotatably connected to the fixed block through the first rotating connecting block. A threaded rod is inserted into the middle of the rotating block, and a first supporting base plate is fixedly connected to the bottom of the threaded rod. Two nuts are sleeved on the middle of the threaded rod. The first supporting base plate facilitates installation and fixation in a preset position. By adjusting the height of the two nuts, the height of the rotating block on the threaded rod can be adjusted for easy adjustment and use.

[0007] The other crossbar has a first connecting seat symmetrically arranged on both sides of its bottom. The top of the first connecting seat is fixedly connected to a second rotating connecting block, and the bottom of the first connecting seat is rotatably connected to a telescopic support mechanism. The first connecting seat and the crossbar are rotatably connected by the second rotating connecting block, which makes it easy to adjust the rotation direction of the telescopic support mechanism and improve the performance.

[0008] Preferably, the folding rods and crossbars are perpendicular to each other, and multiple folding rods and two crossbars form a frame structure. The support slot is set inside the frame structure, and the cross-sectional shape of the rubber strip is set as a triangle. The folding rods and crossbars form a stable frame, which facilitates the support of the photovoltaic module. The support slots limit the support of the photovoltaic module, and the rubber strip limits its vertical movement to prevent it from swaying.

[0009] Preferably, one of the crossbars is fixedly connected to a handle and two ropes on one side. The ropes are located on both sides of the handle, which facilitates hand handling and movement. The ropes can be used to bind the folded telescopic support mechanism and its folded state, making it convenient for transportation and movement.

[0010] Preferably, the cross-sectional shape of the first rotating connecting block is set to "T" shape, the first rotating connecting block is embedded in the middle of the fixed block, the rotating block is located on both sides of the crossbar, and the fixed block and the rotating block are rotatably connected by the first rotating connecting block.

[0011] Preferably, the diameter of the threaded rod is smaller than the diameter of the through hole of the rotating block, the two nuts are located on the upper and lower sides of the rotating block, and the surface of the first support base plate is provided with mounting holes so that the threaded rod can slide in the middle of the rotating block, which facilitates the adjustment of the height of the rotating block in the middle of the threaded rod.

[0012] Preferably, the second rotating connecting block is embedded at the bottom of the corresponding crossbar, and the cross-sectional shape of the second rotating connecting block is set to "T" shape, so that the first connecting seat and the crossbar are rotatably connected through the second rotating connecting block.

[0013] Preferably, the telescopic support mechanism includes a support rod that rotates at the bottom end of the first connecting seat, an insert rod inserted at the bottom of the support rod, a limit slider and a connector respectively fixedly connected at both ends of the insert rod, a fastening bolt inserted on one side of the bottom of the support rod, and the limit slider is located in the middle of the support rod.

[0014] Preferably, a second connecting seat is provided at the bottom of the connector, and a third rotating connecting block is fixedly connected to the bottom of the connector. The cross-sectional shape of the third rotating connecting block is set to "T" shape. The third rotating connecting block is embedded in the middle of the second connecting seat. A second connecting plate is rotatably connected to the bottom of the second connecting seat, and a second supporting base plate is fixedly connected to the bottom of the second connecting plate. Mounting holes are opened around the second supporting base plate. The insert rod can move up and down along the supporting rod, thereby adjusting the overall length of the telescopic support mechanism. The movement range of the insert rod is limited by the limiting slider to prevent the insert rod from completely dislodging from the supporting rod. When the insert rod is adjusted to a suitable position, the fastening bolt is tightened to fix the insert rod to the supporting rod, ensuring the stability of the length of the telescopic support mechanism. The rotation angle of the second connecting seat and the insert rod can be adjusted by rotating the second connecting seat and the second connecting plate through the third rotating connecting block, and the second supporting base plate can be used to easily support and fix it in a preset position.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model firstly reduces the size of the device by folding the folding rod towards the horizontal bar, thereby reducing the space occupied during transportation and lowering transportation costs. It also saves storage space and facilitates management during storage. When in use, unfolding the folding rod forms a stable frame structure, providing a support frame for the photovoltaic modules. The photovoltaic modules can be directly inserted into the support slots without the need for complex bolt connections, which greatly shortens the installation time, reduces the technical requirements for installers, and improves installation efficiency.

[0017] 2. This utility model also features a rotating block and a fixed block that are rotatably connected. By adjusting the height of the threaded rod, the height of one end of the frame can be adjusted, making it convenient and flexible to use. The telescopic support mechanism can support the other end of the frame, and the support length can be adjusted and fixed by pulling the plug rod and rotating the fastening bolt. This allows it to adapt to different installation foundation heights and flexibly adjust the tilt angle of the photovoltaic modules to adapt to different regional sunlight conditions, thereby improving the performance.

[0018] In summary, through the interaction of the above-mentioned multiple functions, the device can be easily folded to significantly reduce its size and transportation costs. It can also be unfolded to form a stable frame structure, providing a support frame for photovoltaic modules. This eliminates the need for complex bolt connections, greatly shortens installation time, reduces the technical requirements for installers, improves installation efficiency, and can adapt to installation foundations of different heights, allowing for flexible adjustment of the tilt angle of the photovoltaic modules.

During transportation and storage, the folding rods 2 can be folded towards the horizontal bars 1, greatly reducing the size of the device. When in use, the folding rods 2 are unfolded to form a stable frame structure, providing a support frame for the photovoltaic module. The first connecting plate 3 connects the two folding rods 2 on the same side into a whole, enhancing the connection strength between the folding rods 2 and preventing the folding rods 2 from shaking or deforming during use, thus ensuring the stability of the frame structure. Support slots 4 are provided at the top of both the horizontal bars 1 and the folding rods 2. The support slots 4 are used to accommodate the edge of the photovoltaic module, playing a role in the initial positioning and lateral constraint of the photovoltaic module, preventing the photovoltaic module from sliding left and right on the frame structure. A rubber strip 5 is fixedly connected to the top of the inner cavity of the support slot 4 to further fix the photovoltaic module and prevent it from shaking up and down.

Two nuts 13 are sleeved in the middle of the threaded rod 11. The first supporting base plate 12 facilitates installation and fixation in a preset position. By adjusting the height of the two nuts 13, the height of the rotating block 9 on the threaded rod 11 can be adjusted for easy adjustment and use.

[0028] The bottom of the other crossbar 1 is symmetrically provided with a first connecting seat 14 on both sides. The top of the first connecting seat 14 is fixedly connected to a second rotating connecting block 15, and the bottom of the first connecting seat 14 is rotatably connected to a telescopic support mechanism. The first connecting seat 14 and the crossbar 1 are rotatably connected by the second rotating connecting block 15, which can facilitate the adjustment of the rotation direction of the telescopic support mechanism and improve the use effect.

[0029] As attached Figure 1-5As shown, the folding rod 2 is perpendicular to the crossbar 1. Multiple folding rods 2 and two crossbars 1 form a frame structure. The support slot 4 is set inside the frame structure. The cross-sectional shape of the rubber clip 5 is triangular. One side of one of the crossbars 1 is fixedly connected to a handle 6 and two binding ropes 7, which are located on both sides of the handle 6. The cross-sectional shape of the first rotating connecting block 10 is "T" shaped. The first rotating connecting block 10 is embedded in the middle of the fixed block 8. The rotating block 9 is located on both sides of the crossbar 1. The diameter of the threaded rod 11 is smaller than the diameter of the through hole of the rotating block 9. Two nuts 13 are located on the upper and lower sides of the rotating block 9. The surface of the first support base plate 12 has mounting holes. The second rotating connecting block 15 is embedded in the corresponding crossbar. At the bottom of rod 1, the cross-sectional shape of the second rotating connecting block 15 is set to "T". The folding rod 2 and the crossbar 1 form a stable frame to facilitate the support of the photovoltaic module. The photovoltaic module is supported and limited by the support slot 4, and the upper and lower limits are set by the rubber strip 5 to prevent it from shaking up and down. The handle 6 makes it easy to carry and move. The binding rope 7 can bind the folded telescopic support mechanism and the folded state to facilitate transportation and movement. The first rotating connecting block 10 makes the fixed block 8 and the rotating block 9 rotate and connect, so that the threaded rod 11 slides in the middle of the rotating block 9, which makes it easy to adjust the height of the rotating block 9 in the middle of the threaded rod 11. The second rotating connecting block 15 makes the first connecting seat 14 rotate and connect to the crossbar 1.

[0030] As attached Figure 1 , 2 As shown in Figure 5, the telescopic support mechanism includes a support rod 16 rotatably mounted at the bottom of the first connecting seat 14. A plug rod 17 is inserted into the bottom of the support rod 16. Limiting sliders 19 and connecting heads 20 are fixedly connected to both ends of the plug rod 17, respectively. A fastening bolt 18 is inserted into one side of the bottom of the support rod 16. The limiting slider 19 is located in the middle of the support rod 16. A second connecting seat 22 is located at the bottom of the connecting head 20. A third rotating connecting block 21 is fixedly connected to the bottom of the connecting head 20. The cross-sectional shape of the third rotating connecting block 21 is "T"-shaped. The third rotating connecting block 21 is embedded in the middle of the second connecting seat 22. A second connecting plate 23 is rotatably connected to the bottom of the second connecting seat 22. A second support base plate 24 is fixedly connected to the bottom. The second support base plate 24 has mounting holes around its perimeter.

The movement range of the insertion rod 17 is limited by the limiting slider 19 to prevent the insertion rod 17 from completely dislodging from the support rod 16. After the insertion rod 17 is adjusted to the appropriate position, the fastening bolt 18 is tightened to fix the insertion rod 17 to the support rod 16, ensuring the stability of the length of the telescopic support mechanism. The second connecting seat 22 and the insertion rod 17 can be rotated by the third rotating connecting block 21, which can adjust the rotation angle of the second connecting seat 22 and the second connecting plate 23, and the second support base plate 24 can be used to easily support and fix it in the preset position.

[0031] It is worth noting that the connecting shafts of the support rod 16 and the first connecting seat 14, as well as the connecting shafts of the second connecting seat 22 and the second connecting plate 23, are all set with fastening bolts, which can fix the rotation angle and make it flexible for use.

[0032] The working principle of this utility model is as follows: When in use, the folded device is moved to the roof installation position through the handle 6, the binding rope 7 is untied, and the folding rod 2 is rotated outward and unfolded until the folding rod 2 and the crossbar 1 are perpendicular to each other, forming a frame structure. The edge of the photovoltaic module is aligned with the support slot 4 on the crossbar 1 and the folding rod 2, and slowly pushed in so that the edge of the photovoltaic module is in close contact with the rubber clip 5. The elasticity of the rubber clip 5 initially fixes the photovoltaic module in the frame structure.

[0033] The first support base plate 12 is fixed in the preset position by rivets, and the threaded rod 11 is connected through the middle of the rotating block 9. The height of the two rotating blocks 9 can be adjusted by adjusting the height of the two nuts 13, so as to fix the height position of a crossbar 1.

[0034] The second support base plate 24 is fixed in the preset position by rivets, and the distance between the first connecting seat 14 and the second connecting seat 22 can be adjusted by pulling the plug rod 17, thereby adjusting the height of the crossbar 1 connected there, so as to adjust the tilt angle of the photovoltaic module. The arc-rotated fastening bolt 18 squeezes and fixes the plug rod 17, which can fix the height and facilitate installation and use.
