Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module installation technology, specifically relating to a lightweight photovoltaic module positioning device. Background Technology

[0002] Photovoltaic modules, also known as solar panels, are the core component of a photovoltaic (PV) power generation system. They mainly consist of solar cells, tempered glass, encapsulating film, backsheet, junction box, and frame. Their function is to convert solar energy into electrical energy. Based on the encapsulation method, they can be divided into crystalline silicon modules and thin-film modules, among others. Crystalline silicon modules are currently the most widely used type on the market, characterized by stable conversion efficiency and long lifespan, and are mostly used in ground-mounted power stations, distributed PV, and building-integrated photovoltaic (BIPV) projects. Lightweight PV modules are a sub-type of PV modules, characterized by their lighter weight. This is mostly achieved by simplifying or replacing the heavy components of traditional modules, such as using ultra-thin glass and frameless designs. They are more suitable for residential buildings with limited roof load-bearing capacity and lightweight mobile facilities, expanding the application scenarios of PV power generation.

[0003] Lightweight photovoltaic (PV) modules, due to their lighter weight, are suitable for installation on the roofs of residential buildings, providing electricity to households while reducing their carbon emissions. However, existing positioning devices for PV modules are typically fixed structures. In the face of severe weather such as typhoons, existing positioning devices cannot adjust lightweight PV modules. PV modules on the roof are more susceptible to damage from flying debris. Furthermore, the inability to adjust the tilt angle of PV modules according to the sun's angle in different seasons is also a problem. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a lightweight photovoltaic module positioning device.

[0005] The technical solution adopted to solve the above technical problems is: to provide a lightweight photovoltaic module positioning device, including an overall protective shell and two mounting base rods, with an I-shaped connecting plate fixedly connected to the bottom between the two mounting base rods, and a U-shaped sleeve mechanism fixedly connected to the top of each of the two mounting base rods; Each of the two U-shaped housing mechanisms is equipped with a front adjustment mechanism and a rear adjustment mechanism, and a limiting round rod is fixedly connected between the tops of the two rear adjustment mechanisms; A photovoltaic module is disposed between the two U-shaped housing mechanisms and the limiting round rod. A retraction and adjustment mechanism is installed at the top center of the I-shaped connecting plate. The retraction and adjustment mechanism is used to drive the front-end adjustment mechanism and the rear-end adjustment mechanism.

[0006] Furthermore, the U-shaped housing mechanism includes a U-shaped limiting housing, with a front connecting housing and a rear connecting housing fixedly connected to the front and rear ends of the U-shaped limiting housing, respectively. A first auxiliary spring and a second auxiliary spring are respectively provided inside the front connecting housing and the rear connecting housing.

[0007] The above technical solution uses a U-shaped limiting shell to limit the adjustment of the front and rear adjustment mechanisms. At the same time, the first and second auxiliary springs are compressed during the retraction of the photovoltaic module. When the photovoltaic module is extended, the compressed first and second auxiliary springs can assist in the unfolding of the front and rear adjustment mechanisms, thereby increasing the overall height of the photovoltaic module.

[0008] Furthermore, strip-shaped limiting holes are provided at both the front and rear ends of the U-shaped limiting shell.

[0009] Through the above technical solution, the strip-shaped limiting hole provides space for the first auxiliary extension plate and the second auxiliary extension plate to extend, enabling them to compress the first auxiliary spring and the second auxiliary spring.

[0010] Furthermore, the front-end adjustment mechanism includes a dual-axis support square tube slidably connected to the front end of the U-shaped limiting shell. A first auxiliary extension plate is fixedly connected to the bottom of the front end face of the dual-axis support square tube. A first dual-axis adjustment square tube is rotatably connected to the bottom of the dual-axis support square tube. A first rotating connector is rotatably connected to the bottom of the first dual-axis adjustment square tube.

[0011] Through the above technical solution, during contraction, the retraction and expansion adjustment mechanism drives the first rotating connector, which in turn pulls the first dual-axis adjustment square tube to rotate, causing the dual-axis support square tube to begin to descend, ultimately achieving the descent of the front end of the photovoltaic module.

[0012] Furthermore, the rear adjustment mechanism includes a single-axis support square tube slidably connected to the rear end of the U-shaped limiting shell, a second auxiliary extension plate fixedly connected to the bottom of the rear end face of the single-axis support square tube, a second dual-axis adjustment square tube rotatably connected to the bottom of the single-axis support square tube, a second rotating connector rotatably connected to the bottom of the second dual-axis adjustment square tube, and a round rod connecting block fixedly connected to the top of the single-axis support square tube.

[0013] Through the above technical solution, during shrinkage and adjustment, the shrinkage and adjustment mechanism drives the second rotating connector to pull the second dual-axis adjustment square tube to rotate, causing the single-axis support square tube to begin to descend, and finally the shrinkage or tilt angle adjustment is achieved by the descent of the rear end of the photovoltaic module.

[0014] Furthermore, the round rod connecting blocks in both of the rear adjustment mechanisms are fixedly connected to the limiting round rod.

[0015] Through the above technical solution, two rear adjustment mechanisms are connected by a limiting rod. During contraction and adjustment, the limiting rod will adaptively slide and adjust inside the photovoltaic module.

[0016] Furthermore, the photovoltaic module includes a photovoltaic panel assembly, and a bottom fixing square tube and a fixing adjustment groove plate are fixedly connected to the bottom of the photovoltaic panel assembly, and a third rotating connector is fixedly connected to both sides of the bottom of the bottom fixing square tube.

[0017] The above technical solution connects the two rear-end adjustment mechanisms through a fixed adjustment slot plate and a limiting round rod, and connects the two front-end adjustment mechanisms through two third rotating connecting parts.

[0018] Furthermore, the bottom of the fixed adjustment groove plate is provided with a groove corresponding to the limiting round rod.

[0019] The above technical solution ensures that the grooves allow for connection with the two rear adjustment mechanisms via the limiting rods during the overall shrinkage and adjustment of the photovoltaic module.

[0020] Furthermore, the retraction and adjustment mechanism includes a square protective shell mounted on the top of the I-shaped connecting plate, two rotating shaft seats, a drive motor assembly, and an electric rod assembly. A first threaded rod and a second threaded rod are rotatably connected to the two rotating shaft seats, and the rear end of the second threaded rod is fixedly connected to the output end of the drive motor assembly. A transmission rod is screwed onto both the first and second threaded rods, and a square connecting block is fixedly connected to both ends of the two transmission rods. A fixed circular tooth block is fixedly connected to the outer wall of the rear end of the first threaded rod, and an extension connecting circular rod is fixedly connected to the center of the rear end of the first threaded rod. A fixed circular block is fixedly connected to the outer wall of the front end of the second threaded rod, and a movable circular tooth block is slidably connected to the outer wall of the fixed circular block. A connecting bearing is provided on the outer wall of the movable circular tooth block, and a drive sleeve is provided between the outer wall of the connecting bearing and the output end of the electric rod assembly.

[0021] Through the above technical solution, when adjusting the tilt angle of the photovoltaic module, the electric rod assembly pulls the drive sleeve plate, which in turn drives the movable circular tooth block to disengage from the fixed circular tooth block via the connecting bearing. Then, the drive motor assembly is started, which drives the second threaded rod to rotate. Since the fixed circular tooth block and the movable circular tooth block are not engaged, only the second threaded rod is driven to rotate. This, in turn, moves the corresponding transmission rod, which in turn moves the second rotating connecting parts in the two rear adjustment mechanisms. This, in turn, pulls the two second dual-axis adjustment square tubes to rotate, and the two single-axis support square tubes also descend accordingly, thereby adjusting the overall tilt angle of the photovoltaic module. In response to severe weather, the drive motor assembly reverses its rotation, causing the second threaded rod to rotate. This, in turn, moves the transmission rod, resetting the single-axis support square tube and the second dual-axis adjusting square tube to their vertical positions. Then, the electric rod assembly pushes the drive sleeve plate, engaging the movable and fixed circular tooth blocks. This activates the drive motor assembly, causing the first and second threaded rods to rotate simultaneously. The two transmission rods retract towards the center until the two first and two second rotating connectors are brought to their minimum distance. At this point, the entire photovoltaic module retracts inside the protective shell, effectively protecting it.

[0022] Furthermore, the thread pitch of the threaded grooves on the outer walls of the first threaded rod and the second threaded rod is different. The front end of the second threaded rod is provided with a circular groove corresponding to the extended connecting circular rod. The inner wall of the movable circular tooth block is fixedly connected with multiple limiting blocks, and the outer wall of the fixed circular block is provided with multiple limiting grooves corresponding to the limiting blocks.

[0023] Through the above technical solution, the pitch of the first threaded rod is smaller than that of the second threaded rod. When rotating one revolution, the transmission rod on the second threaded rod moves a greater distance than the other transmission rod, so that the overall height of the rear adjustment mechanism is greater than that of the front adjustment mechanism. The circular groove ensures that when the fixed circular tooth block and the movable circular tooth block are not engaged, although the first threaded rod and the second threaded rod do not affect the rotation, they can still achieve a rotational connection through the extended connecting rod. The limiting block on the inner wall of the movable circular tooth block plays a limiting role in the sliding of the movable circular tooth block.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention, through the design of an overall protective shell, a U-shaped shell mechanism, a front-end adjustment mechanism, a rear-end adjustment mechanism and a retraction adjustment mechanism, can independently drive the second threaded rod to rotate by disengaging the movable round tooth block from the fixed round tooth block when adjusting the tilt angle of the photovoltaic module, thereby independently controlling the rear-end adjustment mechanism to realize the tilt angle adjustment of the photovoltaic module. In the event of severe weather, the movable round tooth block and the fixed round tooth block re-engage, thereby driving the first threaded rod and the second threaded rod to rotate simultaneously through the drive motor assembly, thereby realizing the simultaneous retraction of the front-end adjustment mechanism and the rear-end adjustment mechanism, thereby enabling the photovoltaic module to descend and reduce the tilt angle, and then retract into the overall protective shell for protection. Compared with the existing positioning device, it can not only realize the tilt angle adjustment, but also adjust according to the sun angle in different seasons, and can also retract for protection in the face of severe weather such as typhoons; (2) The present invention By designing the pitch of the first threaded rod to be smaller than that of the second threaded rod, when rotating one revolution, the transmission rod on the second threaded rod moves a greater distance than the other transmission rod, so that the overall height of the rear adjustment mechanism is greater than that of the front adjustment mechanism, so that the front adjustment mechanism and the rear adjustment mechanism with different heights can be synchronized when shrinking and unfolding; (3) By designing the first auxiliary spring and the second auxiliary spring, during the shrinking process of the photovoltaic module, the dual-axis support square tube and the single-axis support square tube will be compressed by the first auxiliary extension plate and the second auxiliary extension plate respectively during the continuous descent of the photovoltaic module. When the photovoltaic module is extended in the future, the compressed first auxiliary spring and the second auxiliary spring can play an auxiliary pushing role for the rise of the dual-axis support square tube and the single-axis support square tube respectively. This also makes the rotation angle of the dual-axis support square tube and the single-axis support square tube larger, and the overall height of the photovoltaic module is greater.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention.

[0028] like Figures 1-9 As shown, a lightweight photovoltaic module positioning device of this embodiment includes an overall protective shell 1 and two mounting base rods 2. An I-shaped connecting plate 3 is fixedly connected to the bottom between the two mounting base rods 2. A U-shaped sleeve mechanism 4 is fixedly connected to the top of each of the two mounting base rods 2. The U-shaped sleeve mechanism 4 includes a U-shaped limiting shell 401. A front connecting shell 402 and a rear connecting shell 403 are fixedly connected to the front and rear ends of the U-shaped limiting shell 401, respectively. A first auxiliary spring 404 and a second auxiliary spring 405 are respectively provided inside the front connecting shell 402 and the rear connecting shell 403. The U-shaped limiting shell 401 plays a limiting role by adjusting the front adjustment mechanism 5 and the rear adjustment mechanism 6, respectively. Meanwhile, during the retraction of the photovoltaic module 8, the first auxiliary spring 404 and the second auxiliary spring 405 are compressed. When the photovoltaic module 8 is extended, the compressed first auxiliary spring 404 and the second auxiliary spring 405 can play an auxiliary role in pushing the front adjustment mechanism 5 and the rear adjustment mechanism 6 respectively, thereby making the overall photovoltaic module 8 rise and fall to a greater height. The front and rear ends of the U-shaped limiting shell 401 are provided with strip-shaped limiting holes, which provide extension space for the first auxiliary extension plate 502 and the second auxiliary extension plate 602, so that they can compress the first auxiliary spring 404 and the second auxiliary spring 405.

[0029] like Figures 1-9As shown, both U-shaped housing mechanisms 4 are equipped with a front adjustment mechanism 5 and a rear adjustment mechanism 6. The front adjustment mechanism 5 includes a dual-axis support square tube 501 slidably connected to the front end of the U-shaped limiting shell 401. A first auxiliary extension plate 502 is fixedly connected to the bottom of the front end face of the dual-axis support square tube 501. A first dual-axis adjustment square tube 503 is rotatably connected to the bottom of the dual-axis support square tube 501. A first rotating connector 504 is rotatably connected to the bottom of the first dual-axis adjustment square tube 503. During retraction, the retraction adjustment mechanism 9 drives the first rotating connector 504, thereby pulling the first dual-axis adjustment square tube 503 to rotate, causing the dual-axis support square tube 501 to begin to descend, ultimately achieving the descent of the front end of the photovoltaic module 8. The rear adjustment mechanism 6 includes a single-axis support square tube 601 slidably connected to the rear end of the U-shaped limiting shell 401. A first auxiliary extension plate 502 is fixedly connected to the bottom of the rear end face of the single-axis support square tube 601. The second auxiliary extension plate 602, the bottom of the single-axis support square tube 601 is rotatably connected to the second dual-axis adjustment square tube 603, the bottom of the second dual-axis adjustment square tube 603 is rotatably connected to the second rotating connector 604, and the top of the single-axis support square tube 601 is fixedly connected to the round rod connecting block 605. During contraction and adjustment, the contraction and adjustment mechanism 9 drives the second rotating connector 604 to pull the second dual-axis adjustment square tube 603 to rotate, causing the single-axis support square tube 601 to begin to descend. Finally, the contraction or tilt angle adjustment is achieved by the descent of the rear end of the photovoltaic module 8. The round rod connecting blocks 605 in the two rear end adjustment mechanisms 6 are fixedly connected to the limiting round rods 7. The two rear end adjustment mechanisms 6 are connected by the limiting round rods 7. During contraction and adjustment, the limiting round rods 7 will adaptively slide and adjust inside the photovoltaic module 8. The limiting round rods 7 are fixedly connected between the tops of the two rear end adjustment mechanisms 6.

[0030] like Figures 1-10 As shown, a photovoltaic module 8 is arranged between the two U-shaped housing mechanisms 4 and the limiting round rod 7. The photovoltaic module 8 includes a photovoltaic panel assembly 801. The bottom of the photovoltaic panel assembly 801 is fixedly connected to a bottom fixed square tube 802 and a fixed adjustment groove plate 803. The bottom sides of the bottom of the bottom fixed square tube 802 are fixedly connected to third rotating connectors 804. The fixed adjustment groove plate 803 and the limiting round rod 7 are used to connect with the two rear adjustment mechanisms 6, and the two third rotating connectors 804 are used to connect with the two front adjustment mechanisms 5. The bottom of the fixed adjustment groove plate 803 has a groove corresponding to the limiting round rod 7. The groove ensures that the photovoltaic module 8 can be connected to the two rear adjustment mechanisms 6 through the limiting round rod 7 during the shrinkage and adjustment process.

[0031] like Figures 1-18As shown, a retraction adjustment mechanism 9 is installed at the top center of the I-shaped connecting plate 3. The retraction adjustment mechanism 9 is used to drive the front adjustment mechanism 5 and the rear adjustment mechanism 6. The retraction adjustment mechanism 9 includes a square protective shell 901 installed on the top of the I-shaped connecting plate 3, two rotating shaft seats 902, a drive motor assembly 907, and an electric rod assembly 914. A first threaded rod 903 and a second threaded rod 904 are rotatably connected to the two rotating shaft seats 902 respectively, and the rear end of the second threaded rod 904 is fixedly connected to the output end of the drive motor assembly 907. A transmission rod 905 is screwed onto both the first threaded rod 903 and the second threaded rod 904. A square connecting block 906 is fixedly connected to both ends of the two transmission rods 905. The outer wall of the rear end of the first threaded rod 903... A fixed circular tooth block 908 is fixedly connected. An extension connecting circular rod 909 is fixedly connected to the center of the rear end of the first threaded rod 903. A fixed circular block 910 is fixedly connected to the outer wall of the front end of the second threaded rod 904. A movable circular tooth block 911 is slidably connected to the outer wall of the fixed circular block 910. A connecting bearing 912 is provided on the outer wall of the movable circular tooth block 911. A drive sleeve 913 is provided between the outer wall of the connecting bearing 912 and the output end of the electric rod assembly 914. When adjusting the tilt angle of the photovoltaic module 8, the electric rod assembly 914 pulls the drive sleeve 913, which in turn drives the movable circular tooth block 911 to disengage from the fixed circular tooth block 908 through the connecting bearing 912. Then, the drive motor assembly 907 is started, which drives the second threaded rod 904 to rotate. The fixed circular tooth block 908 and the movable circular tooth block 911 are not meshed, so they only drive the second threaded rod 904 to rotate. This, in turn, drives the corresponding transmission rod 905 to move, which in turn pulls the second rotating connecting piece 604 in the two rear adjustment mechanisms 6 to move. This, in turn, pulls the two second dual-axis adjusting square tubes 603 to rotate, and the two single-axis supporting square tubes 601 will also descend accordingly. As a result, the tilt angle of the entire photovoltaic module 8 changes. In the event of severe weather, the drive motor assembly 907 reverses the rotation of the second threaded rod 904, which in turn drives the transmission rod 905 to move, causing the single-axis supporting square tube 601 and the second dual-axis adjusting square tube 603 to return to vertical position. Then, the electric rod assembly 914 pushes the drive sleeve 913, which in turn causes the movable circular tooth block 911 and the fixed circular tooth block 904 to move. The circular toothed block 908 engages, activating the drive motor assembly 907, which in turn drives the first threaded rod 903 and the second threaded rod 904 to rotate simultaneously. This causes the two transmission rods 905 to retract towards the center simultaneously until the two first rotating connectors 504 and the two second rotating connectors 604 approach each other to their minimum distance. At this point, the entire photovoltaic module 8 retracts inside the overall protective shell 1, effectively protecting the photovoltaic module 8. The thread pitches of the threaded grooves on the outer walls of the first threaded rod 903 and the second threaded rod 904 are different. The front end of the second threaded rod 904 has a circular groove corresponding to the extended connecting circular rod 909. The inner wall of the movable circular toothed block 911 is fixedly connected with multiple limiting blocks, and the outer wall of the fixed circular block 910 has multiple limiting grooves corresponding to the limiting blocks.The pitch of the first threaded rod 903 is smaller than that of the second threaded rod 904. During one rotation, the transmission rod 905 on the second threaded rod 904 moves a greater distance than the other transmission rod 905, ensuring that the overall height of the rear adjustment mechanism 6 is greater than the overall height of the front adjustment mechanism 5. The circular groove ensures that even when the fixed circular tooth block 908 and the movable circular tooth block 911 are not engaged, the first threaded rod 903 and the second threaded rod 904, while not affecting rotation, can still achieve a rotational connection through the extended connecting rod 909. The limiting block on the inner wall of the movable circular tooth block 911 limits its sliding.

[0032] The working principle of this embodiment is as follows: After installation, the dual-axis support square tube 501 and the first dual-axis adjustment square tube 503 in the front adjustment mechanism 5 are in a vertical state, and the single-axis support square tube 601 and the second dual-axis adjustment square tube 603 in the rear adjustment mechanism 6 are also in a vertical state. At this time, the photovoltaic module 8 is at the maximum tilt angle. When adjusting the tilt angle of the photovoltaic module 8, the electric rod assembly 914 pulls the drive sleeve 913, which in turn drives the movable circular tooth block 911 to disengage from the fixed circular tooth block 908 through the connecting bearing 912. Then, the drive motor assembly 907 is started, which drives the second thread. The rod 904 rotates, and since the fixed circular tooth block 908 and the movable circular tooth block 911 are not meshed, the second threaded rod 904 is driven to rotate alone. This drives the corresponding transmission rod 905 to move, thereby pulling the second rotating connecting piece 604 in the two rear adjustment mechanisms 6 to move. This, in turn, pulls the two second dual-axis adjustment square tubes 603 to rotate, and the two single-axis support square tubes 601 will also descend. As a result, the tilt angle of the entire photovoltaic module 8 changes. At the same time, during the adjustment process, the limiting circular rod 7 slides inside the fixed adjustment slot plate 803 until it slides to the appropriate angle and then stops. When facing severe weather, the drive motor assembly 907 reverses the rotation of the second threaded rod 904, which in turn moves the transmission rod 905, causing the single-axis support square tube 601 and the second dual-axis adjusting square tube 603 to return to vertical position. Then, the electric rod assembly 914 pushes the drive sleeve 913, which in turn engages the movable round tooth block 911 and the fixed round tooth block 908, starting the drive motor assembly 907 and causing the first threaded rod 903 and the second threaded rod 904 to rotate simultaneously. This causes the two transmission rods 905 to retract towards the center at the same time. Since the pitches of the first threaded rod 903 and the second threaded rod 904 are different, the transmission rod 905 on the second threaded rod 904 moves a greater distance than the other transmission rod 905 when rotating one revolution. This ensures that the overall height of the rear adjustment mechanism 6 is greater than the overall height of the front adjustment mechanism 5, until the two first rotating connectors 504 and the two second rotating connectors 604 approach each other to the minimum distance. At this point, the entire photovoltaic module 8 retracts inside the overall protective shell 1, which can effectively protect the photovoltaic module 8. During the retraction of the photovoltaic module 8, the dual-axis support square tube 501 and the single-axis support square tube 601 in the front-end adjustment mechanism 5 and the rear-end adjustment mechanism 6 continuously descend. During the descent, the first auxiliary spring 404 and the second auxiliary spring 405 are compressed by the first auxiliary extension plate 502 and the second auxiliary extension plate 602, respectively. When the photovoltaic module 8 extends later, the compressed first auxiliary spring 404 and the second auxiliary spring 405 can play an auxiliary role in pushing the dual-axis support square tube 501 and the single-axis support square tube 601 to rise, respectively. This also makes the rotation angle of the dual-axis support square tube 501 and the single-axis support square tube 601 larger, and the overall height of the photovoltaic module 8 is greater.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
