Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel support technology, and in particular to an adjustable photovoltaic panel support. Background Technology

[0002] In the field of photovoltaic energy utilization, the photovoltaic panel bracket, as the core structure supporting photovoltaic modules, directly determines the power generation efficiency and long-term operation and maintenance cost of the photovoltaic system through its angle adjustment flexibility and structural load-bearing stability. It is a key technical link in the construction of photovoltaic power plants.

[0003] Chinese utility model patent CN220234541U discloses an adjustable photovoltaic module. This adjustable photovoltaic module includes a fixed bracket and an adjustment mechanism installed next to the fixed bracket for angle adjustment. The adjustment mechanism is equipped with a screw for angle adjustment and a support rod for support. The surface of the fixed bracket has a bottom groove, and the support rod is slidably connected inside the bottom groove. A rotating rod is rotatably connected to the top of the support rod, and pulleys are rotatably connected to both sides of the rotating rod. The pulleys are slidably connected to an upper groove, which is located at the bottom of the photovoltaic panel. A baffle is fixedly connected next to the upper groove, and the support rod is threadedly connected to the screw. This adjustable photovoltaic module can change the position of the support rod, thereby changing the angle of the photovoltaic panel, allowing the photovoltaic panel to adjust according to the angle of the sun, greatly increasing energy conversion efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Although the above-mentioned patent can change the angle of the photovoltaic panel through the screw adjustment structure, its core adjustment component, the screw, is exposed to harsh outdoor environments such as high temperature, high humidity, and sandstorms for a long time. Sand and dust can easily penetrate into the thread gap of the screw, and the thread surface is easily eroded by rainwater and worn by wind and sand friction, which shortens the service life of the screw and causes jamming or jamming during angle adjustment, disrupting the smoothness of the adjustment operation. In severe cases, the screw damage can also cause the bracket adjustment function to fail, requiring shutdown for maintenance, further causing power generation loss and affecting the photovoltaic panel's efficiency in receiving solar radiation. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an adjustable photovoltaic panel support.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable photovoltaic panel support, comprising a base and a photovoltaic panel body, wherein a connecting rod assembly that rotates and cooperates with the photovoltaic panel body is installed on the top of the base, two limiting shells are installed on the top of the base, and an installation shell is installed between the two limiting shells, a driving assembly is provided inside the installation shell, and a translation assembly that cooperates with the driving assembly is provided inside each of the two limiting shells, two connecting blocks are installed on one side of the photovoltaic panel body, and the two connecting blocks respectively rotate and cooperate with the corresponding translation assemblies, a transmission assembly is provided between the driving assembly and the translation assembly, and the transmission assembly is located inside the installation shell, a sliding groove is provided inside the limiting shell, and a flexible dustproof component is slidably fitted in the sliding groove, and the flexible dustproof component is fixedly connected to the translation assembly.

[0007] By adopting the above technical solution, the drive component transmits power synchronously to the translation components on both sides through the transmission component. The translation components push the photovoltaic panel body through the connecting block, and the photovoltaic panel body rotates around the connecting rod component to achieve angle adjustment. At the same time, the flexible dustproof component moves with the translation component and always closes the sliding groove of the limiting shell to protect the internal components.

[0008] Furthermore, the linkage assembly includes a fixing member installed on the top of the base, with L-shaped plates rotatably fitted on both sides of the fixing member, and fixing rods rotatably connected to the L-shaped plates on both sides of the photovoltaic panel body.

[0009] By adopting the above technical solution, when the angle of the photovoltaic panel body is adjusted, the fixing rod rotates around the end of the L-shaped plate, and at the same time the L-shaped plate rotates around the top of the fixing component, forming a double rotation fulcrum structure, which supports the weight of the photovoltaic panel body and allows it to rotate around the fulcrum.

[0010] Furthermore, the transmission assembly includes a main synchronous pulley and a secondary synchronous pulley, and a synchronous belt is fitted on the main synchronous pulley and the secondary synchronous pulley. The main synchronous pulley cooperates with the drive assembly, and the secondary synchronous pulley cooperates with the translation assembly. The main synchronous pulley and the secondary synchronous pulley have the same number of teeth.

[0011] By adopting the above technical solution, when the drive component drives the main synchronous pulley to rotate, the synchronous belt transmits power synchronously to the auxiliary synchronous pulleys on both sides. Since the number of teeth is the same, the rotation speed of the auxiliary synchronous pulleys on both sides is completely consistent, thereby driving the screws of the translation components on both sides to rotate synchronously.

[0012] Furthermore, the drive assembly includes a worm gear rotatably fitted at the bottom of the inner cavity of the mounting housing. A knob is installed at one end of the worm gear located outside the mounting housing. The surface of the knob is provided with anti-slip ridges. A rotating rod is rotatably fitted on the side of the inner cavity of the mounting housing. The axis of the rotating rod is perpendicular to the axis of the worm gear. A worm wheel that meshes with the worm gear is installed on the side of the rotating rod. The inner side of the main synchronizing pulley is fixedly connected to the rotating rod, and the main synchronizing pulley and the rotating rod are coaxially arranged.

[0013] By adopting the above technical solution, when the knob is turned, the worm rotates and meshes with the worm wheel. Due to the deceleration characteristics of the worm and worm wheel, the power is transmitted to the rotating rod after deceleration. The rotating rod drives the main synchronous pulley to rotate. At the same time, the self-locking characteristics of the worm and worm wheel can keep the adjusted position fixed and prevent loosening.

[0014] Furthermore, the translation component includes a square groove formed on the top of the limiting shell, a sliding groove formed on the periphery of the square groove, the square groove communicating with the sliding groove, a screw rotatably fitted inside the sliding groove, the surface of the screw being galvanized for rust prevention, the side of the screw being rotatably connected to the mounting shell, the auxiliary synchronous pulley being installed at the end of the screw located inside the mounting shell, a slider threadedly fitted on the side of the screw, the inner wall of the slider having an internal thread matching the screw, the slider slidably fitting within the sliding groove, a support block slidably connected to the square groove being installed on the top of the slider, the top of the support block rotatably fitting with a connecting block, and the flexible dustproof component being fixedly connected to the support block.

[0015] By adopting the above technical solution, when the auxiliary synchronous wheel drives the screw to rotate, the slider moves linearly along the screw under the guidance of the slide groove, and the support block slides synchronously with the slider in the square groove, thereby pushing the photovoltaic panel body through the connecting block.

[0016] Furthermore, the flexible dustproof component is an accordion-style dust cover, with one end of the flexible dustproof component fixedly connected to the inner wall of the sliding groove and the other end fixedly connected to the side wall of the support block, and the width of the flexible dustproof component is adapted to the width of the sliding groove.

[0017] By adopting the above technical solution, when the support block moves along the square groove, the accordion-style dustproof component extends and retracts with it, always completely sealing the sliding groove and preventing sand, rainwater, dew and other substances from entering the interior of the limiting shell.

[0018] Furthermore, the bottom of the base is equipped with a number of fixing anchors, which are evenly distributed along the length of the base, and the bottom end of the fixing anchors is provided with a conical tip.

[0019] By adopting the above technical solution, during installation, the conical tip can be quickly inserted into the soil or concrete foundation, and the evenly distributed anchors firmly connect the base to the ground, resisting the overturning force generated by wind load, snow load and the weight of the support itself.

[0020] Furthermore, the edge of the photovoltaic panel body is equipped with a protective frame, which is made of aluminum alloy. The inner side of the protective frame is provided with a buffer pad, which is attached to the edge of the photovoltaic panel body.

[0021] By adopting the above technical solutions, the aluminum alloy frame can withstand collisions and impacts during transportation and installation, preventing damage to the edges of the photovoltaic panel; the buffer pad absorbs vibration and impact energy, avoiding surface scratches caused by direct friction between the photovoltaic panel body and the aluminum alloy frame.

[0022] In summary, this utility model has the following beneficial effects: 1. In this application, the adjusting core component screw is placed inside the limiting shell, and the flexible dustproof part, the sliding groove and the square groove form a closed space, thereby avoiding the screw from directly contacting the harsh outdoor environment. The flexible dustproof part adopts an accordion structure, which expands and contracts synchronously with the support block, always sealing the sliding groove and the square groove, completely blocking sand and rainwater from entering the thread gap. The screw surface is galvanized for rust prevention, further enhancing its resistance to rainwater erosion and corrosion.

[0023] 2. In this application, the linkage assembly forms a double rotation fulcrum through the fixing member, L-shaped plate and fixing rod, which not only disperses the weight load of the photovoltaic panel body, but also restricts its rotation trajectory, ensuring a smooth angle adjustment process and reducing the reduction of the solar radiation receiving area of ​​the photovoltaic panel due to unstable adjustment. The worm gear and worm wheel of the drive component have self-locking characteristics, which can firmly lock the angle of the photovoltaic panel after adjustment, preventing angle deviation caused by external forces such as wind load and vibration, ensuring that the photovoltaic panel maintains the optimal receiving angle for a long time, maximizing the solar radiation absorption efficiency and improving the energy conversion rate of the photovoltaic system.

[0027] like Figure 1-7 As shown in the figure, this application discloses an adjustable photovoltaic panel support, including a base 1 and a photovoltaic panel body 4. The top of the base 1 is equipped with a connecting rod assembly that rotates with the photovoltaic panel body 4. The top of the base 1 is equipped with two limiting shells 6, and a mounting shell 7 is installed between the two limiting shells 6. A driving assembly is provided inside the mounting shell 7. A translation assembly that cooperates with the driving assembly is provided inside each of the two limiting shells 6. Two connecting blocks 5 are installed on one side of the photovoltaic panel body 4. The two connecting blocks 5 rotate with the corresponding translation assemblies respectively. A transmission assembly is provided between the driving assembly and the translation assembly, and the transmission assembly is located inside the mounting shell 7. A sliding groove 14 is provided inside the limiting shell 6. A flexible dustproof component 13 is slidably fitted in the sliding groove 14. The flexible dustproof component 13 is fixedly connected to the translation assembly.

[0028] By adopting the above technical solution, the drive component transmits power synchronously to the translation components on both sides through the transmission component. The translation components push the photovoltaic panel body 4 through the connecting block 5. The photovoltaic panel body 4 rotates around the connecting rod component to achieve angle adjustment. At the same time, the flexible dustproof component 13 moves with the translation component and always closes the sliding groove 14 of the limiting shell 6 to protect the internal components.

[0029] Furthermore, the linkage assembly includes a fixing member 2 installed on the top of the base 1, with L-shaped plates 3 rotatably fitted on both sides of the fixing member 2, and fixing rods rotatably connected to the L-shaped plates 3 installed on both sides of the photovoltaic panel body 4.

[0030] By adopting the above technical solution, when the angle of the photovoltaic panel body 4 is adjusted, the fixing rod rotates around the end of the L-shaped plate 3, and at the same time the L-shaped plate 3 rotates around the top of the fixing member 2, forming a double rotation fulcrum structure, which supports the weight of the photovoltaic panel body 4 and allows it to rotate around the fulcrum.

[0031] Furthermore, the transmission assembly includes a main synchronous pulley 19 and a secondary synchronous pulley 20. A synchronous belt 21 is fitted on the main synchronous pulley 19 and the secondary synchronous pulley 20. The main synchronous pulley 19 cooperates with the drive assembly, and the secondary synchronous pulley 20 cooperates with the translation assembly. The main synchronous pulley 19 and the secondary synchronous pulley 20 have the same number of teeth.

[0032] By adopting the above technical solution, when the drive component drives the main synchronous pulley 19 to rotate, the synchronous belt 21 transmits power synchronously to the auxiliary synchronous pulleys 20 on both sides. Since the number of teeth is the same, the rotation speed of the auxiliary synchronous pulleys 20 on both sides is completely consistent, thereby driving the screws 10 of the translation components on both sides to rotate synchronously.

[0033] Furthermore, the drive assembly includes a worm gear 16 rotatably fitted at the bottom of the inner cavity of the mounting housing 7. A knob 17 is installed at one end of the worm gear 16 located outside the mounting housing 7. The surface of the knob 17 is provided with anti-slip textures. A rotating rod 15 is rotatably fitted on the side of the inner cavity of the mounting housing 7. The axis of the rotating rod 15 is perpendicular to the axis of the worm gear 16.

The inner side of the main synchronizing pulley 19 is fixedly connected to the rotating rod 15, and the main synchronizing pulley 19 is coaxially arranged with the rotating rod 15.

[0034] By adopting the above technical solution, when the knob 17 is turned, the worm 16 rotates and meshes with the worm wheel 18. Due to the deceleration characteristics of the worm 16 and the worm wheel 18, the power is transmitted to the rotating rod 15 after deceleration. The rotating rod 15 drives the main synchronous wheel 19 to rotate. At the same time, the self-locking characteristics of the worm 16 and the worm wheel 18 can keep the adjusted position fixed and prevent loosening.

[0035] Furthermore, the translation component includes a square groove 8 formed on the top of the limiting shell 6, which is connected to the sliding groove 14. A sliding groove 9 is formed on the periphery of the square groove 8. A screw 10 is rotatably fitted inside the sliding groove 9. The surface of the screw 10 is galvanized for rust prevention. The side of the screw 10 is rotatably connected to the mounting shell 7. A secondary synchronous wheel 20 is installed at one end of the screw 10 located inside the mounting shell 7. A slider 11 is threadedly fitted on the side of the screw 10. The inner wall of the slider 11 is provided with an internal thread that matches the screw 10. The slider 11 is slidably fitted in the sliding groove 9. A support block 12 is installed on the top of the slider 11 and is slidably connected to the square groove 8. The top of the support block 12 is rotatably fitted to the connecting block 5. A flexible dustproof component 13 is fixedly connected to the support block 12.

[0036] By adopting the above technical solution, when the auxiliary synchronous wheel 20 drives the screw 10 to rotate, the slider 11 moves linearly along the screw 10 under the guidance of the slide groove 9, and the support block 12 slides synchronously with the slider 11 in the square groove 8, thereby pushing the photovoltaic panel body 4 through the connecting block 5.

[0037] Furthermore, the flexible dustproof component 13 is an accordion-style dust cover. One end of the flexible dustproof component 13 is fixedly connected to the inner wall of the sliding groove 14, and the other end is fixedly connected to the side wall of the support block 12. The width of the flexible dustproof component 13 is adapted to the width of the sliding groove 14.

[0038] By adopting the above technical solution, when the support block 12 moves along the square groove 8, the accordion-style dustproof component 13 extends and retracts with it, always sealing the sliding groove 14 and the square groove 8, preventing sand, rainwater, dew and other substances from entering the interior of the limiting shell 6.

[0039] Furthermore, the bottom of the base 1 is equipped with several anchor bolts, which are evenly distributed along the length of the base 1, and the bottom of the anchor bolts is provided with a conical tip.

[0040] By adopting the above technical solution, during installation, the conical tip can be quickly inserted into the soil or concrete foundation, and the evenly distributed anchors firmly connect the base 1 to the ground, resisting the overturning force generated by wind load, snow load and the weight of the support itself.

[0041] Furthermore, a protective frame is installed on the edge of the photovoltaic panel body 4. The protective frame is made of aluminum alloy and a buffer pad is provided on the inner side of the protective frame. The buffer pad is attached to the edge of the photovoltaic panel body 4.

[0042] By adopting the above technical solutions, the aluminum alloy frame can resist collisions and impacts during transportation and installation, preventing damage to the edges of the photovoltaic panel; the buffer pad absorbs vibration and impact energy, avoiding surface scratches caused by direct friction between the photovoltaic panel body 4 and the aluminum alloy frame.

[0043] The operating principle of an adjustable photovoltaic panel bracket in this embodiment is as follows: The operator rotates the knob 17 on the outside of the mounting shell 7, which drives the worm gear 16 to rotate. The worm gear 16 meshes with the worm wheel 18, transmitting power to the rotating rod 15. The rotating rod 15 drives the coaxial main synchronous wheel 19. The main synchronous wheel 19 drives the auxiliary synchronous wheels 20 in the two limiting shells 6 through the synchronous belt 21, realizing the synchronous transmission of power on both sides. The auxiliary synchronous wheels 20 drive the screw 10 in the limiting shell 6 to rotate. The slider 11 moves along the screw 10 under the guidance of the sliding groove 9, synchronously driving the support block 12 to slide in the square groove 8. The support block 12 pushes the photovoltaic panel body 4 through the connecting block 5. The photovoltaic panel body 4 rotates around the connecting rod assembly to realize the angle change. When the support block 12 moves, the flexible dustproof part 13 extends and retracts with it, always sealing the sliding groove 14 and the square groove 8 to prevent sand and rainwater from entering the interior of the limiting shell 6. The base 1 is fixed to the ground by the fixing anchor bolts, and the photovoltaic panel body 4 resists external forces through the protective frame.
