Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically to an industrial plant photovoltaic support with a TPO waterproof connection structure. Background Technology

[0002] With the accelerated global energy structure transformation, photovoltaic power generation, as a core form of clean and renewable energy utilization, is seeing a continuous increase in its application penetration rate in the industrial sector. Industrial plants, due to their large roof areas and stable sunlight conditions, have become the primary installation carriers for distributed photovoltaic systems. As the connection hub between photovoltaic modules and the plant roof, the structural stability and waterproof sealing of the photovoltaic bracket directly determine the safe operating life of the photovoltaic system and the normal functionality of the plant. However, existing photovoltaic brackets have the following shortcomings in actual use: Most existing photovoltaic (PV) brackets have a fixed tilt angle, making it inconvenient to adjust the angle of the PV modules according to the latitude of the installation location, roof slope, and seasonal changes in sunlight. This results in a significant reduction in the effective irradiance received by the PV modules, directly reducing the power generation of the PV system. At the same time, strong wind loads and rain and snow impacts in the outdoor environment also cause dynamic impacts on the PV brackets. The lack of vibration damping structure design in existing PV brackets means that vibrations and impacts are directly transmitted to the frame of the PV modules, glass panels, and bracket connection nodes. This causes the bolts at the connection nodes between the bracket and the TPO waterproof roof to loosen and the sealant to crack under repeated vibrations, increasing the risk of roof leakage. Furthermore, when the tilt angle of the PV bracket increases, the windward area of ​​the PV modules and the wind load moment also increase, requiring higher anti-overturning and vibration resistance capabilities of the bracket. When the tilt angle decreases, the proportion of vertical load borne by the bracket increases, and the vibration transmission path and amplitude also change. Even if a fixed damping structure is added to the existing brackets, the damping intensity cannot be adjusted according to the tilt angle, resulting in poor damping effect.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0004] The purpose of this invention is to provide an industrial plant photovoltaic support with a TPO waterproof connection structure to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an industrial plant photovoltaic support with a TPO waterproof connection structure, comprising a support body, a chassis at the bottom of the support body, a fixing plate fixed at the top of the support body, and a TPO waterproof sleeve on the outer side of the support body; an mounting plate is provided above the fixing plate; it also includes connecting plates, two of which are symmetrically fixedly connected to the upper surface of the chassis; a tilt adjustment assembly is provided inside the lower part of the support body, and the tilt adjustment assembly includes a worm gear, the worm gear bearing being connected inside the lower part of the support body; a rotating shaft is penetratingly connected to the outer surface of the lower end of the support body, and a worm gear is fixedly sleeved on the outer side of the rotating shaft; a transmission rod is connected to the internal bearing of the support body, and the bottom end of the transmission rod is connected to the outer side of the rotating shaft via a bevel gear set; cylinders are bolted to the upper surface of the fixing plate, and piston cylinders are penetratingly connected to the top of the inner wall of the four cylinders; a shock-absorbing spring is fixed to the top of the inner wall of the piston cylinder; and a shock-absorbing adjustment assembly is provided inside the fixing plate.

[0006] Preferably, the support body is rotatably connected between two connecting plates via a rotating shaft, and the support body is sealed and bonded to the roof of the factory building via a TPO waterproof sleeve, forming a seamless integrated waterproof connection structure.

[0007] Preferably, one end of the worm penetrates the outer surface of the support body and the TPO waterproof sleeve, and the worm is distributed above the worm wheel, and the worm and the worm wheel are meshed together.

[0008] Preferably, the four cylinders are distributed at equal angles around the upper surface of the fixing plate, the outer side of the piston cylinder is connected to the inner wall of the cylinder in a sealed sliding manner, and the lower surface of the mounting plate is fixedly connected to the top of the four piston cylinders by shock-absorbing plates and bolts.

[0009] Preferably, the shock absorption adjustment assembly includes threaded rods, four of which are bearing-connected inside the fixed plate. A driven gear is fixedly fitted on the outer side of the lower end of the threaded rod, and a threaded sleeve is fitted on the outer side of the upper end of the threaded rod. A drive gear is fixedly fitted on the outer side of the upper end of the transmission rod. The upper surface of the fixed plate has grooves at equal angles, and sliders are slidably connected inside the four grooves. The four sliders are connected to the mounting plate via movable plates. A connecting plate is fixedly connected at equal angles to the outer side of the upper end of the transmission rod. Buffer magnets are provided on the opposite surfaces of the four connecting plates and the four sliders.

[0010] Preferably, the four driven gears are distributed at equal angles with respect to the center point of the drive gear inside the fixed plate, and all four driven gears are meshed with the drive gear.

[0011] Preferably, the top of the threaded rod extends into the interior of the piston cylinder, and the threaded rod is rotatably connected to the cylinder body. The threaded sleeve is threadedly connected to the threaded rod, and the top of the threaded sleeve is fixedly connected to the end of the shock-absorbing spring away from the piston cylinder. The outer side of the threaded sleeve is slidably connected to the inner wall of the piston cylinder.

[0012] Preferably, the four connecting plates are distributed at equal angles on the outside of the transmission rod, and the positions of the buffer magnets on the connecting plates correspond to the positions of the buffer magnets on the slider, and the magnetic poles of the buffer magnets on the connecting plates and the buffer magnets on the slider are the same.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention relies on the meshing transmission structure of worm gear and worm wheel. Rotating the worm gear can drive the photovoltaic support chassis to achieve precise tilt angle deflection, which can flexibly adapt to industrial factory roofs with different slopes. At the same time, by utilizing the self-locking characteristics of worm gear and worm wheel, the tilt angle of the support body can be maintained stably for a long time after adjustment, without the need for additional locking components, which simplifies the support body structure and reduces assembly and maintenance costs.

[0014] 2. In this invention, after the tilt angle is adjusted to the correct position, the base on the main body of the support is mechanically fixed by anchor nails. Then, the TPO waterproof sleeve is seamlessly bonded to the roof TPO waterproof membrane and the base on the main body of the support through a hot air hot melt process, forming an integrated sealed structure. This not only ensures the structural stability of the main body of the support installation, but also eliminates the risk of leakage at the connection nodes, realizes the integrity and continuity of the roof waterproof system, and improves the waterproof reliability of the photovoltaic system in roof applications.

[0015] 3. In this invention, when photovoltaic modules sway due to strong winds, the damping plate can directly absorb and attenuate some of the vibration energy, reducing the transmission efficiency of vibration to the support body; the reverse elastic force generated by the piston cylinder driving the damping spring compression can further offset the vibration impact; combined with the sliding of the movable plate driving the slider, the like pole repulsion between the slider and the magnet built into the groove forms a reverse repulsive force. Through the synergistic dissipation of elastic force and magnetic repulsion, the vibration resistance stability of the support is greatly improved, effectively protecting the photovoltaic modules and the support connection structure, and extending the service life of the equipment.

[0016] 4. This invention enables adaptive adjustment of vibration damping performance based on the inclination angle of the support. When the chassis inclination angle is adjusted, the rotating shaft drives the transmission rod to rotate through the bevel gear set. On one hand, this drives the circumferentially distributed threaded rod to rotate synchronously, driving the threaded sleeve to move axially to precisely compress the vibration damping spring, changing the spring preload to adapt to the load distribution characteristics of the support after the inclination angle is adjusted. On the other hand, it drives the connecting plate to deflect, causing the buffer magnet to move to the corresponding position, increasing the magnet contact area to enhance the magnetic repulsion strength, ensuring that the support has the optimal vibration damping effect under different inclination angle conditions, and enhancing the adaptability of the photovoltaic support to complex roof environments.

[0019] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0020] Please see Figures 1-9This invention provides a technical solution: an industrial plant photovoltaic support with a TPO waterproof connection structure, comprising a support body 1, a base plate 3 at the bottom of the support body 1, a fixing plate 4 fixed to the top of the support body 1, and a TPO waterproof sleeve 2 fitted on the outer side of the support body 1. The support body 1 is rotatably connected between two connecting plates 6 via a rotating shaft 803. The support body 1 is sealed and bonded to the roof of the plant through the TPO waterproof sleeve 2, forming a gapless integrated waterproof connection structure. An mounting plate 5 is provided above the fixing plate 4. It also includes connecting plates 6, two connecting plates 6 are symmetrically fixedly connected to the upper surface of the chassis 3, the upper surface of the fixing plate 4 is bolted with cylinders 10, and piston cylinders 11 are connected through the top of the inner wall of the four cylinders 10. The top of the inner wall of the piston cylinders 11 is fixed with shock-absorbing springs 12. The four cylinders 10 are distributed at equal angles around the upper surface of the fixing plate 4. The outer side of the piston cylinder 11 and the inner wall of the cylinder 10 are sealed and slidably connected. The lower surface of the mounting plate 5 is fixedly connected to the top of the four piston cylinders 11 by shock-absorbing plates 14 and bolts.

[0021] In one embodiment of the present invention, the operator first completes the positioning and layout work on the factory roof to determine the precise installation points of the photovoltaic brackets, and simultaneously measures the actual slope parameters of the roof. Then, using the tilt adjustment component, the tilt angle of the bracket base 3 is adaptively adjusted to perfectly match the roof slope, ensuring the flatness of the bracket installation reference surface. Based on this, the operator lays the TPO waterproof sleeve 2 and sequentially inserts the anchor bolts on the base 3 through the TPO waterproof sleeve 2 and the pre-fabricated installation holes on the roof, anchoring and securing them to the roof load-bearing structure (such as steel purlins or...). A concrete base layer is used to ensure the load-bearing stability of the support. Then, a hot air gun is used to heat the bottom of the TPO waterproof sleeve 2 until its surface reaches a molten state. The TPO waterproof sleeve 2 is then heat-fused to the original TPO waterproof membrane on the roof, forming a seamless and sealed structure between the TPO waterproof sleeve 2 and the support base 3. This eliminates the risk of leakage at the connection between the support and the roof and ensures the integrity and continuity of the roof waterproofing system. Finally, the photovoltaic support bracket and the mounting plate 5 are fastened together to complete the assembly of the main support structure 1.

[0022] An inclination adjustment assembly is provided at the lower part of the support body 1. The inclination adjustment assembly includes a worm gear 801. The worm gear 801 is connected to the lower part of the support body 1 by a bearing. A rotating shaft 803 is connected through the outer surface of the lower end of the support body 1. The worm gear 801 is fixedly sleeved on the outer side of the rotating shaft 803. A transmission rod 7 is connected to the bearing inside the support body 1. The bottom end of the transmission rod 7 is connected to the outer side of the rotating shaft 803 by a bevel gear set 13. One end of the worm 802 passes through the outer surface of the support body 1 and the TPO waterproof sleeve 2. The worm 802 is distributed above the worm gear 801, and the worm 802 and the worm gear 801 are meshed.

[0023] In one embodiment of the present invention, by rotating the worm gear 802, the worm wheel 801 meshing with it is driven to rotate synchronously. The worm wheel 801 drives the connected rotating shaft 803 to rotate in conjunction, thereby causing the base 3 of the photovoltaic support to produce a precise tilt angle deflection to adapt to industrial factory roofs with different slopes. At the same time, thanks to the self-locking property of the worm gear 802 and the worm wheel 801, the tilt angle of the adjusted support body 1 can be stably maintained without the need for additional locking parts.

[0024] The fixed plate 4 houses a shock-absorbing adjustment assembly, which includes threaded rods 907. Four threaded rods 907 are bearing-connected to the inside of the fixed plate 4. A driven gear 906 is fixedly fitted onto the outer side of the lower end of each threaded rod 907, and a threaded sleeve 908 is fitted onto the outer side of the upper end of each threaded rod 907. The top of each threaded rod 907 extends into the piston cylinder 11, and the threaded rod 907 is rotatably connected to the cylinder body 10. The threaded sleeve 908 is threadedly connected to the threaded rod 907, and the top of the threaded sleeve 908 is fixedly connected to the end of the shock-absorbing spring 12 away from the piston cylinder 11. The outer side of the threaded sleeve 908 is slidably connected to the inner wall of the piston cylinder 11. A drive gear 909 is fixedly fitted onto the outer side of the upper end of the transmission rod 7, and the four driven gears 906 are related to the drive gear 909. The center points are evenly distributed inside the fixed plate 4, and the four driven gears 906 and the drive gear 909 are all meshed. The upper surface of the fixed plate 4 is provided with sliding grooves 904 at equal angles, and the sliding blocks 902 are slidably connected inside the four sliding grooves 904. The four sliding blocks 902 are connected to the mounting plate 5 through movable plates 903. The outer side of the upper end of the transmission rod 7 is fixedly connected with connecting plates 901 at equal angles. The opposite surfaces of the four connecting plates 901 and the four sliding blocks 902 are provided with buffer magnets 905. The four connecting plates 901 are evenly distributed on the outer side of the transmission rod 7, and the positions of the buffer magnets 905 on the connecting plates 901 and the buffer magnets 905 on the sliding blocks 902 are corresponding, and the magnetic poles of the opposite surfaces of the buffer magnets 905 on the connecting plates 901 and the buffer magnets 905 on the sliding blocks 902 are the same.

[0025] In one embodiment of the present invention, when the photovoltaic module sways due to strong winds, the damping plate 14 first absorbs and attenuates part of the vibration energy, reducing the transmission efficiency of vibration to the support body 1. At the same time, the piston cylinder 11 slides downward inside the cylinder 10 with the vibration, and the damping spring 12 arranged inside the cylinder 10 is compressed to generate a reverse elastic force, further offsetting the vibration impact. During this process, the movable plate 903 rotates synchronously and pushes the slider 902 to slide smoothly along the preset slide groove 904. Combined with the principle of like pole repulsion between the slider 902 and the buffer magnet 905 on the connecting plate 901, a repulsive force opposite to the vibration direction is formed. Through the synergistic effect of elastic force and magnetic repulsion, multi-stage dissipation of vibration is achieved, greatly improving the vibration resistance stability of the support body 1. When the chassis 3 is tilted according to the slope of the factory roof, the rotating shaft 803 connected to the chassis 3 rotates synchronously and passes through the bevel gear. The meshing transmission of wheel set 13 drives the transmission rod 7 to rotate; the transmission rod 7 drives the drive gear 909 at its end to rotate synchronously, which in turn meshes with and drives the four circumferentially distributed driven gears 906 to rotate synchronously, causing the threaded rod 907 coaxially connected to the driven gears 906 to rotate accordingly. At the same time, the rotation of the threaded rod 907 drives the threaded sleeve 908 that is threadedly engaged with it to move axially upward, forming a precise compression on the damping spring 12 at the bottom of the threaded sleeve 908, thereby changing the preload of the damping spring 12 and adapting to the load distribution characteristics of the support after the tilt angle is adjusted; at the same time, the rotation of the transmission rod 7 synchronously drives the four circumferentially arranged connecting plates 901 to deflect at an angle, causing the buffer magnet 905 on the connecting plate 901 to move to the corresponding position of the buffer magnet 905 on the slider 902, increasing the contact area of ​​the two buffer magnets 905, thereby increasing the strength of the magnetic repulsion force and realizing the adaptive adjustment of the damping performance with the tilt angle of the support.

[0026] Working Principle: When using this industrial photovoltaic support with a TPO waterproof connection structure, the operator first completes the positioning and layout on the roof of the factory building, determines the installation point of the support body 1, and measures the roof slope. Then, rotating the worm gear 802 drives the meshing worm wheel 801 to rotate. The worm wheel 801 drives the rotating shaft 803 in conjunction, causing the base plate 3 on the support body 1 to precisely deflect to an angle matching the roof slope. Utilizing the self-locking characteristics of the worm gear 802 and worm wheel 801, the adjusted tilt angle can be stably maintained without the need for additional locking components, ensuring... The mounting base surface of the support body 1 is flat. After laying the TPO waterproof sleeve 2, the anchor bolts on the base plate 3 are penetrated through the TPO waterproof sleeve 2 and the pre-fabricated installation holes on the roof, and anchored and tightened to the roof load-bearing structure. The bottom of the TPO waterproof sleeve 2 is heated with a hot air gun until its surface melts, and then it is thermally bonded to the original TPO waterproof membrane on the roof. At the same time, it forms a seamless sealing structure with the base plate 3 on the support body 1, which not only ensures the load-bearing stability of the support body 1, but also eliminates the risk of leakage at the connection nodes, and achieves the integrity of the roof waterproofing system. Finally, the photovoltaic... The support bracket is fastened to the mounting plate 5, completing the assembly of the support body 1. When the photovoltaic module is shaken by strong winds, the damping plate 14 first absorbs and attenuates part of the vibration energy; at the same time, the piston cylinder 11 slides down in the cylinder 10, compressing the damping spring 12 to generate a reverse elastic force to offset the impact; during this process, the movable plate 903 drives the slider 902 to slide along the slide groove 904, and the like pole repulsion between the slider 902 and the buffer magnet 905 on the connecting plate 901 forms a reverse repulsive force. Through the synergistic effect of elastic force and magnetic repulsion, multi-stage vibration dissipation is achieved. The damping effect is enhanced by adjusting the tilt angle of the chassis 3. When the tilt angle of the chassis 3 is adjusted, the rotating shaft 803 drives the transmission rod 7 to rotate through the bevel gear set 13. On the one hand, it drives the circumferential threaded rod 907 to rotate, and drives the threaded sleeve 908 to move axially to precisely compress the damping spring 12, change the spring preload, and adapt to the load distribution after the tilt angle is adjusted. On the other hand, it drives the connecting plate 901 to deflect, so that the buffer magnet 905 is displaced to the corresponding position, increases the magnet contact area to enhance the magnetic repulsion strength, and realizes the adaptive adjustment of the damping performance with the tilt angle of the support.
