Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, specifically to a photovoltaic panel module and a photovoltaic panel mounting structure. Background Technology

[0002] Photovoltaic modules, also known as solar cell modules, refer to the smallest indivisible assembly of photovoltaic cells that is encapsulated and internally connected, capable of independently providing direct current (DC) output. A photovoltaic power generation system mainly consists of the following components: Solar panels (photovoltaic modules): Solar panels are the core component of a photovoltaic power generation system, used to convert sunlight into electrical energy. They are composed of multiple solar cells, typically made of silicon, and can convert the light energy in sunlight into DC electrical energy.

[0003] For example, Chinese patent publication number "CN120474451B" discloses "a photovoltaic panel module and a photovoltaic panel installation structure". Its main structure includes a base, a mounting frame, a photovoltaic frame assembly, and a drive mechanism. The mounting frame is installed on the base. The photovoltaic frame assembly includes a first frame and a second frame arranged on the mounting frame. The drive mechanism includes a drive plate installed on the mounting frame. The actuating end of the drive plate is connected to the second frame. When the drive plate drives the second frame away from the first frame, an air duct is opened in the mounting frame. When strong winds are depressurized and discharged towards the sunny side of the roof through the exhaust space, most of them are intercepted by the secondary depressurization component and blown back onto the back of the photovoltaic panel on the first frame. Under the guidance of the secondary depressurization component and the back of the photovoltaic panel, they are released towards the lower side of the sunny side of the roof. Even if the strong winds are quickly degraded and unloaded, the strong winds are discharged in a reasonable manner, thereby reducing the damage of strong winds to the roof. The depressurization structure is more reasonable.

[0004] However, in the initial installation process of the aforementioned photovoltaic panel components and photovoltaic panel installation structure, since the photovoltaic panel can only be adjusted at one angle, the direction of its deviation from the rotation axis cannot be adjusted. Therefore, it is necessary to ensure that the installation base plate of the equipment is in a horizontal state when the foundation is poured. In fact, when the poured cement is solidifying, the installation base plate is very likely to tilt, resulting in poor horizontal reference during the installation of the equipment, which affects the actual angle installation of the photovoltaic panel. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a photovoltaic panel module and a photovoltaic panel installation structure that enables three-dimensional angle adjustment of the photovoltaic panel after the foundation has solidified. It has low requirements for the horizontal reference accuracy of the base, thereby improving the accuracy of angle control after installation. Furthermore, the device can adaptively buffer vibrations generated in the installation area, improving the equipment's anti-interference capability and reducing the negative impact of vibrations on the photovoltaic panel, thus solving the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic panel assembly, comprising multiple photovoltaic panels installed inside a rectangular support, and four elastic buffer support mechanisms, the structure of which includes an upper limit plate located below the corner of the rectangular support, a lower limit plate located directly below the upper limit plate and providing support for the upper limit plate, a limit rope that generates a downward pulling force on the upper limit plate, a second helical spring located between the upper limit plate and the lower limit plate and providing elastic support, and a first helical spring placed inside the lower limit plate and generating a downward preload force on the limit rope.

[0011] Preferably, the ball joint angle control mechanism further includes a second docking plate for fixing the embedded block and the fixed sphere. The center of the spherical hollow disk is provided with a spherical mounting cavity sleeved around the central area of ​​the fixed sphere. The spherical hollow disk is provided with an annular storage cavity around the central area of ​​the spherical mounting cavity. A locking airbag is embedded in the spherical hollow disk at the junction of the annular storage cavity and the spherical mounting cavity. One side of the upper surface of the spherical hollow disk is provided with an inflation channel for filling the annular storage cavity with gas and a valve installed inside. The other side of the upper surface of the spherical hollow disk is provided with a first docking channel connecting the annular storage cavity. Four horizontal support frames are installed on the outer circumference of the spherical hollow disk. Each horizontal support frame has a horizontal mounting plate at its end. Each horizontal mounting plate has a bolt hole in its center for placing the middle part of the bolt rod. The nut is installed on the outer periphery of the bolt rod below the bolt hole.

[0012] Preferably, the structural radius of the spherical surface of the spherical mounting cavity is adapted to the structural radius of the fixed sphere, and the diameter of the openings at the top and bottom of the spherical mounting cavity is greater than the structural radius of the fixed sphere and less than the structural diameter of the fixed sphere.

[0013] Preferably, the adaptive pressure control mechanism further includes a horizontal movable cavity disposed inside a horizontal hollow tube. The center of the horizontal movable cavity is divided into two by a limiting protrusion ring, forming a second pressure control cavity on the side closer to the spherical hollow disk and a first pressure control cavity on the side farther from the spherical hollow disk. One end of the horizontal hollow tube is provided with a second docking channel connecting the second pressure control cavity and a first docking channel. The other end of the horizontal hollow tube is provided with an internal threaded hole and an exhaust hole connecting the external space and the first pressure control cavity. An internal valve plate capable of moving along its axial direction is placed in the second pressure control cavity, and an internal limiting plate capable of moving along its axial direction is placed in the first pressure control cavity. A third helical spring in a compressed state is placed between the internal valve plate and the internal limiting plate. The circumferential surfaces of the internal valve plate and the internal limiting plate are provided with multiple gas flow grooves for gas flow. An external threaded rod is installed in the internal threaded hole through a threaded structure, and one end of the external threaded rod is connected to one end of the internal limiting plate through a bearing.

[0014] Preferably, the distance between the gas flow channel and the center line of the horizontal hollow tube is less than the distance between the limiting protrusion and the center line of the horizontal hollow tube.

[0015] Preferably, when the built-in limiting plate abuts against one end of the internal threaded hole, the gas sealing resistance formed by the built-in valve plate is sufficient to keep the rectangular bracket in a static state when not subjected to manual torsion; when the built-in limiting plate abuts against one end of the second docking channel, the gas sealing resistance formed by the built-in valve plate is sufficient to keep the rectangular bracket in a static state when subjected to manual torsion.

[0016] Compared with the prior art, the present invention provides a photovoltaic panel module and a photovoltaic panel mounting structure, which have the following beneficial effects: 1. The device enables three-dimensional angle adjustment of photovoltaic panels after the foundation has solidified, with low requirements for the horizontal reference accuracy of the base, thereby improving the accuracy of angle control after installation and fixing of photovoltaic panels. In addition, the device can adaptively buffer vibrations generated in the installation area to improve the anti-interference ability of the equipment and reduce the negative impact of vibration on photovoltaic panels.

[0017] 2. An elastic buffer support mechanism is set up, with the upper limit plate and lower limit plate as the main body, and the No. 1 and No. 2 helical springs compressed and tightened and the tension limit rope forming a composite elastic buffer system. The No. 2 helical spring attenuates vertical vibration, and the No. 1 spring pulls the limit rope to drive the built-in movable plate to quickly reset the upper limit plate. The dual elastic structure can continuously absorb ground vibration and suppress aftershock swaying, effectively isolate the vibration from being transmitted to the photovoltaic panel, reduce the risk of module cracking and line damage, and the support is arranged at four corners with uniform force distribution, resulting in stronger vibration reduction stability.

[0018] 3. Equipped with a ball-joint angle control mechanism, it adopts a universal ball-joint structure consisting of a pre-embedded block, a fixed sphere, and a spherical hollow disk. Combined with the built-in locking airbag in the annular storage cavity for friction locking, the sphere can be twisted arbitrarily within the spherical installation cavity. Precise leveling of the concrete base is not required beforehand. Even after the foundation has solidified, the three-dimensional pitch and deflection angles of the photovoltaic panel can still be freely adjusted. The inflated airbag achieves reliable locking by increasing friction through air pressure. It is equipped with four sets of horizontal support frames that are bolted to the support mechanism, resulting in a stable overall connection and multi-angle adjustment without dead angles, significantly reducing the difficulty of leveling on-site.

[0019] 4. An adaptive pressure control mechanism is provided. The horizontal hollow tube has a limiting protrusion ring that separates two pressure control chambers. The compression of the No. 3 helical spring is changed by adjusting the position of the internal limiting plate by the external threaded rod, thereby controlling the sealing resistance of the internal valve plate on the air passage. When the spring is loosened, the air passage flow resistance is small and the airbag locking friction is low, making it easy to manually twist the ball joint to fine-tune the photovoltaic angle. After the spring is tightened, the sealing air pressure of the valve plate is stronger and the airbag locking friction is greatly improved, making it difficult for external forces to shake the bracket. One set of structures can switch between two working pressures: angle adjustment and permanent locking, which can accurately match the two stages of photovoltaic installation and simplify the inflation and locking operation process.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1 and Figure 2 A photovoltaic panel assembly includes multiple photovoltaic panels 2 installed inside a rectangular bracket 1. The multiple photovoltaic panels 2 are installed side by side in the rectangular bracket 1. The angle of the multiple photovoltaic panels 2 can be controlled by controlling the orientation of the rectangular bracket 1.

[0024] To achieve the buffer support function for photovoltaic panel 2, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 Four elastic buffer support mechanisms 3 need to be installed. These mechanisms include an upper limit plate 31 located below the corner of the rectangular support 1; a lower limit plate 34 located directly below the upper limit plate 31 and supporting it; a limiting rope 310 that exerts a downward pulling force on the upper limit plate 31; a second helical spring 39 located between the upper and lower limit plates 31 and providing elastic support; and a first helical spring 38 placed inside the lower limit plate 34 and exerting a downward preload on the limiting rope 310. During equipment operation... Once vibration occurs in the installation area, the vibration will be transmitted upward through the lower limit plate 34. When the vibration is transmitted upward along the second helical spring 39, the elasticity of the second helical spring 39 will reduce the intensity of the vibration. At the same time, the first helical spring 38 will generate a timely downward pulling force on the limit rope 310, which can quickly reset the moving upper limit plate 31 to directly above the lower limit plate 34, thereby reducing the residual vibration phenomenon caused by the vibration. This achieves the buffer support function for the photovoltaic panel 2, so as to reduce the negative impact of vibration on the photovoltaic panel 2 and its internal components.

[0025] For details regarding the specific structure of the elastic buffer support mechanism 3, please refer to [link / reference]. Figure 3 and Figure 4 It also includes a first docking plate 32 integrally disposed on the top of the upper limit plate 31 and fixedly installed at the bottom of the corner of the rectangular bracket 1. The bottom of the lower limit plate 34 is provided with a longitudinal support rod 33 integrally disposed therewith. The interior of the lower limit plate 34 is provided with a longitudinal movable cavity 35. The top of the lower limit plate 34 is provided with a wire hole 36 communicating with the top of the longitudinal movable cavity 35. A second helical spring 39 is fixedly installed between the bottom of the upper limit plate 31 and the top of the lower limit plate 34. The interior of the longitudinal movable cavity 35 is provided with an internal movable plate 37 capable of moving along its axial direction. The upper surface of the internal movable plate 37 is embedded with a limiting pull rope 310 that passes through the wire hole 36. The top end of 310 is fixedly embedded in the bottom center of the upper limit plate 31. A first helical spring 38 that exerts downward pressure on the built-in movable plate 37 is installed in the longitudinal movable cavity 35. A limit contact plate 311 is installed at the bottom end of the longitudinal support rod 33. A bolt rod 312 with an integral structure is provided at the bottom of the limit contact plate 311. A nut 313 is installed on the outer periphery of the bolt rod 312 through a threaded structure. The top opening end of the wire hole 36 is provided with a rounded corner structure to facilitate the movement of the limit pull rope 310 after bending. In the working state, the limit pull rope 310 is in a taut state, and both the first helical spring 38 and the second helical spring 39 are in a compressed state.

[0026] To implement the angle adjustment function in three-dimensional space, please refer to [link / reference]. Figure 1 , Figure 2, Figure 5 and Figure 6 A ball-joint angle control mechanism 4 needs to be installed. Its structure includes an embedded block 41 that can be embedded inside a concrete base, a fixed sphere 43 located above the embedded block 41, a spherical hollow disc 44 that is sleeved around the central area of ​​the fixed sphere 43 and can be twisted, and a locking airbag 47 that can lock the spherical hollow disc 44 and the fixed sphere 43 under air pressure. The embedded block 41 is embedded in the uncured concrete base. After the concrete base has solidified, an inflation device is used to fill the annular storage cavity 45 with gas through the inflation channel 48. When the gas first passes through the exhaust port 513... During discharge, the inflation of the inflation device is paused. At this time, the frictional locking force of the locking airbag 47 on the fixed ball 43 will keep the rectangular support 1 in a stationary state. Then, a torsional force is manually applied to the rectangular support 1. When the torsional force is greater than the above-mentioned frictional locking force, the fixed ball 43 will undergo an adaptive angular rotation, and the rectangular support 1 will change its angle accordingly until the angle of the rectangular support 1 matches the working angle of the photovoltaic panel 2. Then, gas can be replenished into the annular storage cavity 45 through the inflation device to achieve complete locking of the fixed ball 43, thereby realizing the angle adjustment function in three-dimensional space.

[0027] For details regarding the specific structure of the ball joint angle control mechanism 4, please refer to [link / reference]. Figure 5 and Figure 6 It also includes a second docking plate 42 for fixing the pre-embedded block 41 and the fixed sphere 43. The spherical hollow disk 44 has a spherical mounting cavity 46 at its center, which is sleeved around the central area of ​​the fixed sphere 43. The spherical hollow disk 44 has an annular storage cavity 45 around the central area of ​​the spherical mounting cavity 46. A locking airbag 47 is embedded in the spherical hollow disk 44 at the junction of the annular storage cavity 45 and the spherical mounting cavity 46. One side of the upper surface of the spherical hollow disk 44 has an inflation channel 48 for filling the annular storage cavity 45 with gas and equipped with a valve. The other side of the upper surface of the spherical hollow disk 44 has a channel connecting to the annular storage cavity 45. The first docking channel 49 of 5 has four horizontal support frames 410 installed on the outer circumference of the spherical hollow disk 44. Each horizontal support frame 410 has a horizontal mounting plate 411 at its end. Each horizontal mounting plate 411 has a bolt hole 412 in its middle for placing the middle part of the bolt rod 312. The nut 313 is installed on the outer periphery of the bolt rod 312 below the bolt hole 412. The structural radius of the spherical surface of the spherical mounting cavity 46 is adapted to the structural radius of the fixed sphere 43. The diameter of the opening at the top and bottom of the spherical mounting cavity 46 is larger than the structural radius of the fixed sphere 43 and smaller than the structural diameter of the fixed sphere 43.

[0028] To achieve air pressure control under different operating conditions, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 7 and Figure 8 An adaptive pressure control mechanism 5 needs to be set up. Its structure includes a horizontal hollow tube 51 located on one side of the spherical hollow disk 44 and with a hollow internal structure, an internal valve plate 58 located inside the horizontal hollow tube 51 and capable of controlling the gas flow state, a No. 3 helical spring 510 that generates elastic pressure on the internal valve plate 58, and an external threaded rod 512 that can change the elastic strength of the No. 3 helical spring 510. During the initial inflation, the external threaded rod 512 needs to be rotated in a directional manner. Under the influence of the threaded structure, when the internal limiting plate 511 abuts against one end of the internal threaded hole 57, the No. 3 helical spring 510 is in a primary compression state, the internal valve plate 58 is not fully pressed against the limiting protrusion ring 53, and the gas passage is in a throttling and conducting state. At this time, the initial air pressure is maintained inside the locking airbag 47. The static friction torque generated by it on the fixed ball 43 is greater than the self-weight off-center load torque of the rectangular bracket 1, keeping it stationary in its natural state. When the applied external torque overcomes the static friction torque, the rectangular bracket 1 can be rotated to adjust the angle. After the angle adjustment is completed, the external thread rod 512 is screwed in the opposite direction, so that the built-in limiting plate 511 abuts against one end of the second docking channel 56. The third helical spring 510 reaches its maximum compression, and the built-in valve plate 58 is fully compressed and blocks the air passage. The locking airbag 47 achieves peak pressure maintenance, and the ultimate friction torque generated by it is greater than the set maximum human torque and wind load torque, achieving overall static locking. At this time, the locking airbag 47 can achieve the final locking effect on the fixed ball 43. This effect can ensure the working angle of the rectangular bracket 1, thereby realizing the air pressure control function under different working conditions.

[0029] For details regarding the specific structure of the adaptive pressure control mechanism 5, please refer to [link / reference]. Figure 7 and Figure 8It also includes a horizontal movable cavity 52 disposed inside the horizontal hollow tube 51. The center of the horizontal movable cavity 52 is divided into two by a limiting protrusion ring 53. A second pressure control cavity 54 is formed on the side closer to the spherical hollow disk 44, and a first pressure control cavity 55 is formed on the side farther away from the spherical hollow disk 44. One end of the horizontal hollow tube 51 is provided with a second docking channel 56 connecting the second pressure control cavity 54 and the first docking channel 49. The other end of the horizontal hollow tube 51 is provided with an internal threaded hole 57 and an exhaust hole 513 connecting the external space and the first pressure control cavity 55. An internal valve plate 58 capable of moving along its axial direction is placed in the second pressure control cavity 54. An internal limiting plate 511 capable of moving along its axial direction is placed in the first pressure control cavity 55. A third helical spring 510 in a compressed state is placed between the internal valve plate 58 and the internal limiting plate 511. The circumferential surfaces of the built-in valve plate 58 and the built-in limiting plate 511 are provided with multiple gas flow grooves 59 for gas flow. An external threaded rod 512 is installed in the internal threaded hole 57 through a threaded structure. One end of the external threaded rod 512 is connected to one end of the built-in limiting plate 511 through a bearing. The distance between the gas flow groove 59 and the center line of the horizontal hollow tube 51 is less than the distance between the limiting protrusion ring 53 and the center line of the horizontal hollow tube 51. When the built-in limiting plate 511 abuts against one end of the internal threaded hole 57, the gas sealing pressure formed by the built-in valve plate 58 is sufficient to keep the rectangular support 1 in a static state without being manually twisted. When the built-in limiting plate 511 abuts against one end of the second docking channel 56, the gas sealing pressure formed by the built-in valve plate 58 is sufficient to keep the rectangular support 1 in a static state when being manually twisted.

[0030] In use, the pre-embedded block 41 is embedded in the uncured concrete base. After the concrete base has solidified, the inflation device is used to fill the annular storage cavity 45 with gas through the inflation channel 48. When the gas is first discharged out through the exhaust hole 513, the inflation device is stopped. At this time, the friction locking force of the locking airbag 47 on the fixed ball 43 will keep the rectangular support 1 in a stationary state. Then, a torsional force is manually applied to the rectangular support 1. When the torsional force is greater than the above friction locking force, the fixed ball 43 will undergo an adaptive angular rotation, and the rectangular support 1 will change its angle accordingly until the angle of the rectangular support 1 matches the working angle of the photovoltaic panel 2. Then, the inflation device can be used to replenish the annular storage cavity 45 with gas again to achieve complete locking of the fixed ball 43. During the above-mentioned process, the following steps need to be followed: During the initial inflation, the external threaded rod 512 needs to be rotated in a directional manner. Under the influence of the threaded structure, when the built-in limiting plate 511 abuts against one end of the internal threaded hole 57, the No. 3 helical spring 510 is in a primary compression state, the built-in valve plate 58 is not fully pressed against the limiting protrusion ring 53, and the air passage is in a throttling and conducting state. At this time, the initial air pressure is maintained inside the locking airbag 47. The static friction torque generated by it on the fixed ball 43 is greater than the self-weight off-center load torque of the rectangular bracket 1, so that it remains stationary in its natural state. When the applied external torque overcomes the static friction torque, the rectangular bracket 1 can be rotated to adjust the angle. After the angle adjustment is completed, the external thread rod 512 is screwed in the opposite direction, so that the built-in limiting plate 511 abuts against one end of the second docking channel 56. The third helical spring 510 reaches the maximum compression, and the built-in valve plate 58 is fully compressed and blocks the air passage. The locking airbag 47 achieves peak pressure maintenance. The ultimate friction torque generated by it is greater than the set maximum human torque and wind load torque, so as to achieve overall static locking. At this time, the locking airbag 47 can achieve the final locking effect on the fixed ball 43. This effect can ensure the working angle of the rectangular bracket 1. During equipment operation, if vibration occurs in the installation area, the vibration will be transmitted upward through the lower limit plate 34. When the vibration is transmitted upward along the second helical spring 39, the elasticity of the second helical spring 39 will reduce the intensity of the vibration. At the same time, the first helical spring 38 will exert a timely downward pulling force on the limit rope 310, which will enable the moving upper limit plate 31 to quickly return to the position directly above the lower limit plate 34, thereby reducing the residual vibration phenomenon caused by the vibration. This achieves the buffer support function for the photovoltaic panel 2, thereby reducing the negative impact of vibration on the photovoltaic panel 2 and its internal components.
