Description

Technical Field

[0001] This invention belongs to the field of photovoltaic installation devices, specifically a stable rooftop photovoltaic panel support that is resistant to strong winds. Background Technology

[0002] Solar photovoltaic (PV) panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Currently, many factories or farms install solar PV panels on their roofs to save on electricity costs or meet low-carbon and environmental protection requirements, in order to replace or supplement grid power. PV panels installed on factory roofs effectively utilize unused roof space without occupying valuable factory area, and have fewer obstructions and better sunlight conditions. However, the lack of obstructions also means that PV panels are easily overturned by strong winds, causing significant economic losses. Therefore, rooftop PV panels usually need to consider the need for strong wind protection.

[0003] For example, Chinese patent CN120150604A discloses a windproof photovoltaic support and its construction method, including a support assembly and a sealing plate. The support assembly includes longitudinal beams, purlins, and waterproof strips, with multiple longitudinal beams, purlins, and waterproof strips. The sealing plate is installed around the perimeter of the roof surface and is also sealed to the photovoltaic panel located at the edge of the roof surface, so that the sealing plate can seal the gap between the photovoltaic panel located at the edge of the roof surface and the roof surface. This application seals the gap between the photovoltaic panel located at the edge of the roof surface and the roof surface by setting a sealing plate, preventing airflow from entering between the roof surface and the photovoltaic panel through the gap, thereby reducing the probability of the photovoltaic panel being blown away by the wind and improving the wind resistance of the photovoltaic panel.

[0004] However, the aforementioned patents still have the following drawbacks:

[0005] 1. In actual strong wind environments, not only can strong winds blow into the gap between the photovoltaic panels and the roof, lifting and overturning the photovoltaic panels, but also, due to the limited roof area, the photovoltaic panels are arranged relatively closely and have a smooth surface. When high-speed strong winds flow across the surface of the photovoltaic panels, especially when the strong winds flow parallel to the surface of the photovoltaic panels, they will be affected by the Bernoulli effect, which will generate a strong lifting force on the photovoltaic panels. The aforementioned patent cannot solve this problem.

[0006] 2. In actual strong wind environments, strong winds can easily carry hard debris such as sand, gravel, and dead branches. These debris can easily cause damage to the photovoltaic panels by hard collision or scratching, which can also cause economic losses. The aforementioned patents are unlikely to provide effective protection for the photovoltaic panels.

[0007] 3. Although the above-mentioned patent reduces the gap between the roof and the photovoltaic panel by setting a sealing plate to indirectly improve the wind resistance of the photovoltaic panel, it cannot directly improve the connection stability between its support and the roof. Therefore, in strong wind environment, its installation and connection structure still have to bear a large load, which may loosen after a long time and lead to failure to be firmly fixed, ultimately causing the photovoltaic panel to be overturned by strong wind. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, this invention addresses the technical problem by incorporating a shielding layer. In the event of strong winds, the shielding layer slides along a chain from the bottom of the inner support plate to above the photovoltaic panel, covering it. The pressure-induced wrinkles in the shielding layer disrupt the smoothness of the photovoltaic panel surface, reducing the wind velocity and thus decreasing the lifting force caused by the Bernoulli effect, thereby stabilizing the panel. The flexible shielding layer provides cushioning protection, preventing direct damage to the photovoltaic panel surface from sand, gravel, twigs, and other hard debris carried by strong winds. The wrinkles formed by the pressure on the photovoltaic panel surface further enhance the shielding layer's energy absorption effect, improving its protective capabilities. This is achieved by incorporating a deceleration mechanism. The machine-driven winding sleeve winds up the pull rope, pulling the shielding layer from the bottom of the inner support plate to the top of the photovoltaic panel. After the shielding layer is pulled into place, the tensioned pull rope provides additional tension, which further resists the lifting force of strong winds at the bottom of the inner support plate during strong winds. This distributes the load to the horizontal and side support plates, ensuring the connection stability between the horizontal and side support plates and preventing them from loosening and becoming unstable. By setting vents and grid plates, the heat dissipation effect is improved. When strong winds flow from the bottom of the inner support plate, the grid plates guide the airflow into the cable housing and finally out through the vents, further reducing the lifting force of strong winds on the inner support plate and photovoltaic panel when strong winds flow at the bottom of the inner support plate, thus stabilizing the photovoltaic panel.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a stable, wind-resistant rooftop photovoltaic panel support, comprising:

[0010] A plurality of horizontal support plates are evenly spaced and installed at a designated location on the roof, with multiple sets of photovoltaic modules arranged side by side between each two horizontal support plates.

[0011] The photovoltaic module includes two symmetrically arranged side support plates, each side support plate is fixedly connected to an adjacent horizontal support plate, an inner support plate is fixedly connected between the two side support plates, and a photovoltaic panel is fixedly connected to the top of each inner support plate;

[0012] Each of the side support plates is slidably connected to a chain on its inner side, and a flexible covering layer is fixedly connected between two chains. The covering layer can be moved from below the inner support plate to above the photovoltaic panel to shield the photovoltaic panel.

[0013] Furthermore, the chain is formed by hinged connections of multiple first links, second links, and link pins. Each side support plate has a U-shaped groove on its inner side. The ends of each link pin extending from the first and second links extend into the corresponding groove and slide in connection with the groove. Multiple links are evenly distributed and embedded in the covering layer. The two ends of each link are fixedly connected to the extension of the second link.

[0014] Furthermore, the covering layer is made of elastic rubber material, the surface of the covering layer is implanted with a brush layer, and the covering layer is squeezed to form wrinkles between every two sections.

[0015] Furthermore, a sprocket shaft is rotatably connected between the two side support plates at the rotation position of the slide groove. Two sprockets are fixedly connected to both ends of the sprocket shaft, and each sprocket is engaged with the adjacent chain for transmission.

[0016] Furthermore, an inner support wheel is rotatably connected to the sprocket shaft, and brackets sleeved on the outside of the sprocket shaft are respectively provided at both ends of the inner support wheel. The inner support wheel is in contact with the inner side of the covering layer.

[0017] Furthermore, a bracket is fixedly connected between the two side support plates at the location between the sprocket shaft and the inner support plate. Two baffles are fixedly connected to the side of the bracket near the sprocket shaft. The inner support wheel is located between the two baffles. Each baffle is connected to the adjacent sprocket by a torsion spring that surrounds the outside of the sprocket shaft.

[0018] Furthermore, pulleys are rotatably connected to the inner ends of the two side support plates away from the sprocket shaft, and a pulley seat is fixedly connected to each side support plate near the pulley. Each pulley is rotatably connected to its corresponding pulley seat, and a connector is hinged to one end of each chain. A tension steel rope is fixedly connected to the connector, and each tension steel rope passes around the outside of the corresponding pulley.

[0019] Furthermore, each inner support plate is provided with multiple bearing seats below it, and a winding shaft is rotatably connected between the multiple bearing seats in the same row. A winding sleeve is fixedly connected to each winding shaft at the corresponding position of each pulling steel rope. The end of each pulling steel rope away from the connector is wound and fixed with the corresponding winding sleeve. A reduction motor is drivenly connected to one end of each winding shaft.

[0020] Furthermore, a hollow cable cover is fixedly connected between the two side support plates at one end of the inner support plate, and each side support plate has a through cable opening at the corresponding position of the cable cover.

[0021] Furthermore, the cable cover has an opening on one side that communicates with the bottom side of the inner support plate, and multiple ventilation holes are evenly distributed on the upper surface of the cable cover. Two sets of grid plates are evenly distributed on the bottom side of the inner support plate, and the two sets of grid plates are symmetrical to each other and point towards the cable cover.

[0022] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) By setting a shading layer, when encountering strong winds, the shading layer can slide from the bottom of the inner support plate to the top of the photovoltaic panel with the chain to cover the photovoltaic panel. The shading layer, which is squeezed and forms wrinkles, makes the surface of the photovoltaic panel no longer smooth, thereby reducing the flow rate of strong winds on the surface of the photovoltaic panel, thereby reducing the lifting force on the photovoltaic panel caused by the Bernoulli effect, and achieving the effect of stabilizing the photovoltaic panel.

[0024] (2) The flexible covering layer can buffer and protect the surface of the photovoltaic panel. When strong winds carry sand, gravel, dead branches and other hard debris to the photovoltaic panel, the debris will not directly damage the surface of the photovoltaic panel. The wrinkles formed by the covering layer on the surface of the photovoltaic panel due to compression can make the covering layer achieve better buffering and energy absorption effect, and improve the protection of the photovoltaic panel.

[0025] (3) By setting a geared motor to drive the winding sleeve to wind up the pulling steel rope, the action of pulling the covering layer from the bottom of the inner support plate to the top of the photovoltaic panel is realized. After the covering layer is pulled into place, the pulling steel rope is tightened and can provide additional tension. In the event of strong wind, it can further resist the lifting force of the strong wind at the bottom of the inner support plate, share the load for the horizontal support plate and side support plate, and ensure the connection stability of the horizontal support plate and side support plate, so as to avoid the problem of loosening and failure to be firmly fixed.

[0026] (4) By setting up ventilation holes and grid plates to improve heat dissipation, and when strong winds flow from the bottom side of the inner support plate, the grid plates guide the airflow into the cable cover and finally discharge it from the ventilation holes, which further reduces the lifting force of strong winds on the inner support plate and photovoltaic panel when they flow at the bottom of the inner support plate, thus stabilizing the photovoltaic panel.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] Example 1:

[0039] like Figure 1-9 As shown, a sturdy, wind-resistant rooftop photovoltaic panel support includes horizontal support plates 10 and multiple sets of photovoltaic modules. The multiple horizontal support plates 10 are evenly spaced and fixedly connected to the roof. A photovoltaic module is fixedly connected between every two adjacent horizontal support plates 10. Each set of photovoltaic modules includes two symmetrical side support plates 11. An inner support plate 12 is fixedly connected between the two side support plates 11. A photovoltaic panel 13 is fixedly connected to the top of the inner support plate 12.

[0040] The photovoltaic modules can be fixed to the roof by setting the horizontal support plate 10. Different lengths and numbers of horizontal support plates 10 can be selected according to the actual installation conditions and needs to achieve modular installation and adapt to different scenarios.

[0041] like Figure 1-9As shown, each side support plate 11 has a chain 20 on its inner side. Each chain 20 is formed by hinged connections of multiple first chain links 17, second chain links 18 and chain link pins 19. Each side support plate 11 has a U-shaped groove 16 on its inner side. One end of each chain link pin 19 extends out of the first chain link 17 and the second chain link 18 and enters the corresponding groove 16 and slides in connection with the groove 16. A flexible covering layer 22 is fixedly connected between the two chains 20. A brush layer is embedded on the outer surface of the covering layer 22. Multiple links 21 are evenly distributed and embedded in the covering layer 22. The two ends of each link 21 are fixedly connected to the extension of each second chain link 18. The covering layer 22 is squeezed to form folds between the links 21.

[0042] By setting up a shading layer 22, when encountering strong winds, the shading layer 22 can slide along the chain 20 from the bottom of the inner support plate 12 to the top of the photovoltaic panel 13 to cover the photovoltaic panel 13. The shading layer 22, which is squeezed and forms wrinkles, makes the surface of the photovoltaic panel 13 no longer smooth, thereby reducing the flow rate of strong winds on the surface of the photovoltaic panel 13, thus reducing the lifting force on the photovoltaic panel 13 caused by the Bernoulli effect and stabilizing the photovoltaic panel 13.

[0043] Meanwhile, the flexible covering layer 22 can buffer and protect the surface of the photovoltaic panel 13. When strong winds carry sand, gravel, dead branches and other hard debris towards the photovoltaic panel 13, the debris will not directly damage the surface of the photovoltaic panel 13. The wrinkles formed by the compression of the covering layer 22 on the surface of the photovoltaic panel 13 can make the covering layer 22 have a better buffering and energy absorption effect, and improve the protection of the photovoltaic panel 13.

[0044] Furthermore, the brush layer embedded on the surface of the shielding layer 22 can further absorb and slow down the airflow when strong winds blow across the surface of the shielding layer 22. The brush layer itself can also play a buffering and protective role. Combined with the flexible shielding layer 22 and its pleats, it can provide good protection for the photovoltaic panel 13 in strong winds.

[0045] like Figure 1-9 As shown, each covering layer 22 is fixedly connected to a connector 28 at its upper end, and the connector 28 is connected to a tension steel rope 29. A pulley 30 is rotatably connected to the inner side of each side support plate 11 away from the sprocket shaft 14. A pulley seat 31 is fixedly connected to the corresponding position of each side support plate 11 at the pulley 30. Each pulley 30 is rotatably connected to the pulley seat 31. A bearing 33 fixed to the roof is provided below each tension steel rope 29. A winding shaft 34 is rotatably connected between the bearings 33 in the same row. A winding sleeve 32 is fixedly connected to each winding shaft 34 at the corresponding position of the tension steel rope 29. Each tension steel rope 29 passes around the outside of the corresponding pulley 30 and is wound and fixedly connected to the winding sleeve 32. A reduction motor 35 is drivenly connected to one end of each winding shaft 34.

[0046] By setting a geared motor 35 to drive the winding sleeve 32 to wind up the pulling steel rope 29, the action of pulling the covering layer 22 from the bottom of the inner support plate 12 to the upper side of the photovoltaic panel 13 is realized. After the covering layer 22 is pulled into place, the pulling steel rope 29 is tightened and can provide additional tension. In the event of strong wind, it can further resist the lifting force of strong wind at the bottom of the inner support plate 12, and share the load for the horizontal support plate 10 and the side support plate 11, so as to ensure the connection stability of the horizontal support plate 10 and the side support plate 11 and avoid the problem of loosening and failure to be firmly fixed.

[0047] Furthermore, this design ensures that the traction steel cable 29 is in a relaxed state when not encountering strong winds, and is only tightened when encountering strong winds. Compared to setting a traction structure that is always taut, this effectively avoids the problem of metal fatigue caused by prolonged tension and stress on the traction structure, which leads to accelerated aging or even breakage, thus improving service life and reliability.

[0048] like Figure 1-9 As shown, a sprocket shaft 14 is rotatably connected between the two side support plates 11 at the rotation position of the slide groove 16. Two sprockets 15 are fixedly connected to both ends of the sprocket shaft 14. Each sprocket 15 is meshed with the corresponding chain 20 for transmission. A bracket 25 is fixedly connected between the two side support plates 11 at the position between the sprocket shaft 14 and the inner support plate 12. Two baffles 26 are fixedly connected to the side of the bracket 25 near the sprocket shaft 14. The sprocket shaft 14 is rotatably connected to the two baffles 26. A torsion spring 27 surrounding the outside of the sprocket shaft 14 is connected between each baffle 26 and the adjacent sprocket 15.

[0049] By setting up the sprocket 15 and the torsion spring 27, when the traction steel rope 29 pulls the chain 20 and the covering layer 22 above the photovoltaic panel 13, the torsion spring 27 can be twisted to store energy. When the winding sleeve 32 reverses to release the traction steel rope 29, the elasticity of the torsion spring 27 is used to drive the sprocket 15 to rotate. The sprocket 15 then drives the chain 20 and the covering layer 22 to reset, so as to facilitate subsequent use.

[0050] like Figure 1-9 As shown, an inner support wheel 23 is rotatably connected to the sprocket shaft 14. Bearings 24 are provided at both ends of the inner support wheel 23 and are sleeved on the outside of the sprocket shaft 14. The inner support wheel 23 is located between two baffles 26, and the surface of the inner support wheel 23 is in close contact with the inner side of the covering layer 22 at the rotation point.

[0051] By setting the inner support wheel 23, the shading layer 22 can be opened at the turning point to eliminate wrinkles, thereby preventing the shading layer 22 from wrinkling inward at the turning point, which would prevent the subsequent shading layer 22 from being unable to move smoothly above the photovoltaic panel 13. At the same time, the inner support wheel 23 eliminates wrinkles at the turning point, making the process of the shading layer 22 changing its moving direction at the turning point smoother.

[0052] like Figure 1-9 As shown, a hollow cable cover 36 is fixedly connected between the two side support plates 11 at one end of the inner support plate 12. Each side support plate 11 has a through cable opening 37 at the corresponding position of the cable cover 36. The cable cover 36 has an opening on one side that communicates with the bottom side of the inner support plate 12. Multiple ventilation holes 38 are evenly distributed on the upper surface of the cable cover 36. Two sets of grid plates 39 are evenly distributed on the bottom side of the inner support plate 12. The two sets of grid plates 39 are symmetrical to each other and point towards the cable cover 36.

[0053] By setting the cable cover 36 and the cable insertion port 37, it is easy to concentrate the wires of the photovoltaic panels 13 in the same row to the outermost side and then bundle them together. The cable cover 36 can also protect the wires and prevent them from being damaged or broken in strong winds. At the same time, the vent 38 can connect the space at the bottom of the inner support plate 12 with the outside, so that the bottom of the inner support plate 12 can fully exchange heat with the outside, and prevent the shading layer 22 from affecting the heat dissipation effect of the photovoltaic panel 13 when it is on the bottom side of the inner support plate 12.

[0054] Furthermore, by setting up the grille plate 39 to increase the contact area between the bottom side of the inner support plate 12 and the air, the heat dissipation effect is further improved. At the same time, the inclined grille plate 39 can guide the airflow. When encountering strong winds and the covering layer 22 moves above the photovoltaic panel 13, and the strong wind blows from the bottom side of the inner support plate 12, the grille plate 39 guides the airflow into the cable cover 36 and finally discharges it from the vent 38. This further reduces the lifting force of the strong wind on the inner support plate 12 and the photovoltaic panel 13 when the strong wind flows at the bottom of the inner support plate 12, thus stabilizing the photovoltaic panel 13.

[0055] In this embodiment, during installation, the construction workers first install the required horizontal support plates 10 at intervals on the roof, and then install the pre-assembled photovoltaic modules between the horizontal support plates 10 in sequence. At the same time, the winding sleeves 32, shaft seats 33 and winding shafts 34 are installed, and the pulling steel ropes 29 are wound and fixed on each winding sleeve 32. The wires of the photovoltaic panels 13 are passed through the cable cover 36 and the wire through hole 37 and concentrated to the outermost side before being bundled together. Finally, after the main body is installed, the reduction motor 35 is installed and connected to the power supply and control system, thus completing the installation of this device.

[0056] When there is no strong wind, the shading layer 22 is located below the inner support plate 12 and the tension steel cable 29 is in a slack state. All photovoltaic panels 13 are fully exposed to sunlight to convert light energy for power generation. When there is a light breeze in the environment, the airflow blows into the cable cover 36 through the vent 38 and finally into the bottom side of the inner support plate 12, which cools down the bottom side of the inner support plate 12 and prevents the photovoltaic panels 13 from overheating and affecting the power generation efficiency.

[0057] When encountering strong winds, the operator can start each reduction motor 35 through the control system. The reduction motor 35 drives the winding shaft 34 and winding sleeve 32 to rotate and wind up the traction steel rope 29. The traction steel rope 29 pulls the upper end of the section 21 to move towards the pulley 30. Due to the guiding effect of the slide groove 16, the section 21 and the covering layer 22 slide along the contour of the slide groove 16 until the covering layer 22 completely covers the photovoltaic panel 13 and forms wrinkles.

[0058] When strong winds flow over the uneven surface of the shielding layer 22, their velocity is reduced by the shielding layer 22 and the brushes on its surface. This makes it difficult for the strong winds to generate a Bernoulli effect and lift the photovoltaic panel 13. At the same time, once the shielding layer 22 is pulled into place, it cannot move further. The tensioning steel cable 29 provides additional tension to share the lifting force of the strong winds under the inner support plate 12. Furthermore, when the strong winds flow under the inner support plate 12, they are guided by the grid plate 39 to flow into the cable cover 36 and finally exit from the vent 38. This further reduces the lifting force of the strong winds on the bottom side of the inner support plate 12, making the device more robust against strong winds.

[0059] During the movement of the chain 20 and the covering layer 22 under the traction of the steel cable 29, the sprocket 15 is driven by the chain 20 to rotate, causing the torsion spring 27 to twist and store energy. When the strong wind dissipates, the operator drives the reduction motor 35 in the opposite direction to release the steel cable 29. Then, the torsion spring 27 uses the stored elastic potential energy to drive the sprocket 15 to reverse, thereby driving the chain 20 and the covering layer 22 to reset.

[0060] Each photovoltaic module in this device is relatively independent. Therefore, if one group of photovoltaic modules is damaged, the damaged photovoltaic module can be directly replaced as a whole, which facilitates maintenance.

[0061] Example 2:

[0062] Compared to Embodiment 1, in this embodiment, the shielding layer 22 has brush layers on both its front and back sides. The brush on the side of the shielding layer 22 away from the photovoltaic panel 13 is longer and stiffer, while the brush on the side of the shielding layer 22 closer to the photovoltaic panel 13 is shorter and finer. When the steel cable 29 pulls the shielding layer 22 to cover the photovoltaic panel 13, the fine brush on the inner side of the shielding layer 22 will brush and clean the surface of the photovoltaic panel. Thus, when there is a lot of dust on the surface of the photovoltaic panel, or after rain, the operator can control the shielding layer 22 to move once or multiple times to clean the surface of the photovoltaic panel, avoiding the impact of dust and rainwater on the power generation efficiency of the photovoltaic panel.
