Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel support application technology, and particularly relates to a photovoltaic panel support with automatic angle adjustment. Background Technology

[0002] Photovoltaic panel brackets are important components used in solar photovoltaic power generation systems for placing, installing, and fixing solar panels. There are many types of photovoltaic brackets, which can be classified into various categories according to different classification methods.

[0003] Existing technologies disclose several invention patents in the field of photovoltaic panel support applications. Among them, patent CN118508858B discloses a photovoltaic panel support, including a support base. A U-shaped mounting bracket is fixed to the top of the support base. A shaft seat is rotatably connected to the top of the U-shaped mounting bracket. A rotating rod is rotatably connected inside the shaft seat. A transmission block is fixed to the outside of the rotating rod. A mounting plate is fixed to the end of the transmission block away from the rotating rod. A photovoltaic panel is slidably connected to the top of the mounting plate. U-shaped cleaning frames are slidably connected to both sides of the mounting plate. The inner side of the U-shaped cleaning frames is slidably connected to the photovoltaic panel. This design effectively adjusts the photovoltaic panel and rotating rod according to the sun's trajectory in multiple directions, maximizing the absorption of light energy by the photovoltaic panel and significantly improving the device's performance. While this technical solution offers practicality and flexibility, it still has some shortcomings in practical application. To make it easier for installers to position, fix, and connect the photovoltaic panels, reducing installation time and costs, and to make it easier for maintenance personnel to inspect, clean, and replace faulty photovoltaic panels to ensure the stable operation of the photovoltaic system, multiple photovoltaic panels are often installed in a neat arrangement. Since photovoltaic panels are mostly installed in open areas with abundant wind resources, the large interception surface formed by the neatly arranged photovoltaic panels results in significant wind resistance, which in turn places high demands on the stability of the photovoltaic panel support. This leads to higher production and installation costs for the photovoltaic panel support, and in strong winds, the panels are easily overturned, causing damage to a large number of photovoltaic panels.

[0004] Based on this, the present invention designs a photovoltaic panel bracket with automatic angle adjustment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the problem of photovoltaic (PV) system stability. This is because PV panels are often installed in neat rows, and since they are typically installed in open areas with abundant wind resources, the large interception surface created by the neatly arranged panels results in significant wind resistance. This places high demands on the stability of the PV panel supports, leading to higher production and installation costs. Furthermore, strong winds can easily cause the panels to be overturned, damaging a large number of PV panels. Therefore, this invention proposes an automatically adjustable angle PV panel support.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

A wing plate is provided below the photovoltaic panel body at the ventilation point inside the support component. The wing plate adopts a convex-flat-top airfoil design. A connecting shaft connects the wing plate and the photovoltaic panel body. The wing plate generates a downward force to pull the photovoltaic panel body down through the support component. Multiple photovoltaic panels are misaligned to reduce wind resistance.

The top of the rainwater collection hopper is a sloping structure, and its inclination is equal to the installation angle of the photovoltaic panel body.

A lifting shaft is sleeved in each lifting slot, and a first spring is connected to the end of the lifting shaft. The lifting shaft is elastically supported and connected to the bottom of the lifting slot through the first spring. The top ends of the multiple lifting shafts are connected to the same upper support member.

[0011] As a further description of the above technical solution:

[0012] The upper support includes an upper support frame connected to the top of multiple lifting shafts. Two sliding grooves are opened on the inner side of the upper support frame. A plug is fitted at the opening of the sliding groove. A slider is slidably connected in the sliding groove. A second spring is connected to the end of the slider. The slider is elastically supported and connected to the end of the plug through the second spring. The photovoltaic panel body is connected to the opposite surface of the two sliders.

[0013] As a further description of the above technical solution:

[0014] The photovoltaic panel body is provided with a dustproof component, which includes a multifunctional film attached to the photovoltaic panel body. One end of the multifunctional film is wound and connected to a first winding member connected to a lower support frame, and the other end of the multifunctional film is wound and connected to a second winding member.

[0015] As a further description of the above technical solution:

[0016] The first winding component includes two first winding frames connected to the lower support frame. A first winding shaft is fitted between the two first winding frames. A first winding roller is rotatably connected to the first winding shaft. Both ends of the first winding roller are provided with torsion grooves. A spring is fitted at both ends of the first winding shaft corresponding to the two torsion grooves. The first winding shaft is elastically connected to the inner end face of the two torsion grooves through the two springs respectively.

[0017] As a further description of the above technical solution:

[0018] The second winding component includes two second winding frames connected to the lower support frame. The two second winding frames are rotatably connected to the same second winding shaft. A second winding roller is mounted on the second winding shaft. A gear is mounted on the second winding shaft. A toothed plate meshes on the tooth surface of the gear. An elbow is supported and connected between the toothed plate and the lower support frame.

[0019] As a further description of the above technical solution:

[0020] A pressing assembly is connected to the photovoltaic panel body corresponding to the multifunctional film. The pressing assembly includes a right-angle frame connected to the photovoltaic panel body. Multiple rotating shafts are rotatably connected to the inner side of the right-angle frame. Each of the multiple rotating shafts is fitted with a pressing wheel, and the multiple pressing wheels are rotatably connected to the multifunctional film.

[0021] As a further description of the above technical solution:

[0022] A filter plate is embedded in the port at the top of the water receiving hopper, a water receiving pipe is connected to the bottom of the water receiving hopper, and the other end of the water receiving pipe is connected to a water storage tank.

[0023] As a further description of the above technical solution:

[0024] The cleaning assembly includes two adapter frames connected to the upper support frame, and a cleaning tube is rotatably connected between the two adapter frames. The outer wall of the cleaning tube has two sets of spray holes facing the multifunctional membrane. Each set of spray holes has multiple holes, and the openings of the two sets of spray holes face both sides of the multifunctional membrane.

[0025] A piston cylinder is connected to the lower support frame. The piston rod of the piston cylinder is connected to the upper support frame. A discharge pipe is connected to the piston cylinder. The other end of the discharge pipe is connected to a cleaning pipe. An inlet pipe is connected to the piston cylinder. The other end of the inlet pipe is connected to a water storage tank. A one-way valve is installed on both the inlet pipe and the discharge pipe.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, when strong winds flow over the wingplates, the wingplates generate a downward force. The wingplates apply this downward force to the photovoltaic panel body via a connecting shaft. On one hand, the photovoltaic panel body slides in the sliding groove via a slider and undergoes elastic deformation based on a second spring. On the other hand, the photovoltaic panel body applies the downward force to the upper support frame via the slider. The upper support frame sinks in multiple lifting slots via multiple lifting shafts and simultaneously compresses multiple first springs to cause elastic deformation. This allows the photovoltaic panel body to slide sideways and sink when subjected to the downward force. Since the wind direction and wind force of the strong winds act on the multiple wingplates to a certain extent, misalignment will occur between the arranged photovoltaic panels, reducing resistance to strong winds and improving the stability of the photovoltaic system to a certain extent.

[0028] 2. In this invention, rainwater in the piston cylinder flows into the cleaning pipe through the discharge pipe, and is finally sprayed out towards both sides of the multifunctional membrane through two sets of spray holes to rinse and clean the surface of the multifunctional membrane. When the wind weakens, the photovoltaic panel body rises under the elastic restoring force of the first and second springs, the one-way valve on the discharge pipe closes, and the one-way valve on the inlet pipe opens. The piston cylinder draws rainwater from the water storage tank through the inlet pipe for subsequent use. The rainwater is used to clean the surface of the multifunctional membrane, so that the multifunctional membrane on the top of the photovoltaic panel body is in a clean state, ensuring the light transmittance of the multifunctional membrane and improving the photovoltaic power generation efficiency of the device.

[0029] 3. In this invention, the photovoltaic panel body achieves a better cleaning effect with a smaller amount of water or rainwater. The function of the multifunctional film is to reduce the physical adsorption or adhesion between dust and the surface of the photovoltaic panel body, including van der Waals forces, capillary forces and electrostatic attraction, which can significantly reduce the impact of dust on the light transmittance of the photovoltaic panel, thereby improving power generation efficiency and reducing operation and maintenance costs.

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.

[0043] Please see the attached Figure 1 -Attached Figure 10 The present invention provides a technical solution: an automatic angle-adjustable photovoltaic panel support, including a support component 1 with telescopic function, a photovoltaic panel body 2 connected to the inner side of the top of the support component 1, and a wing plate 4 provided below the photovoltaic panel body 2 corresponding to the ventilation area inside the support component 1. The wing plate 4 adopts an airfoil design with a convex bottom and a flat top. A connecting shaft 5 connects the wing plate 4 and the photovoltaic panel body 2. The wing plate 4 generates a downward force to pull the photovoltaic panel body 2 down through the support component 1, and multiple photovoltaic panel bodies 2 are misaligned to reduce wind resistance.

[0044] The support component 1 has a water collection hopper 7 connected to the lower edge of the photovoltaic panel body 2 on its side end. The top of the water collection hopper 7 is a sloping structure, and its inclination is equal to the installation angle of the photovoltaic panel body 2. The support component 1 has a cleaning component 11 connected to the upper edge of the photovoltaic panel body 2 to utilize rainwater for cleaning.

[0045] Specifically, the support assembly 1 includes a lower support frame 101. The top of the lower support frame 101 has multiple lifting slots 102. Lifting shafts 103 are sleeved within the lifting slots 102. A first spring 104 is connected to the end of each lifting shaft 103. The lifting shaft 103 is elastically supported and connected to the bottom of the lifting slot 102 via the first spring 104. The tops of the multiple lifting shafts 103 are connected to the same upper support member 105. The upper support member 105 includes an upper support frame 1051 connected to the tops of the multiple lifting shafts 103. Two sliding grooves 105 are formed on the inner side of the upper support frame 1051. 2. A plug 1053 is fitted at the opening of the groove 1052. A slider 1054 is slidably connected inside the groove 1052. A second spring 1055 is connected to the end of the slider 1054. The slider 1054 is elastically supported and connected to the end of the plug 1053 near the second spring 1055. The photovoltaic panel body 2 is connected to the opposite surfaces of the two sliders 1054. A dustproof component 3 is provided on the photovoltaic panel body 2. The dustproof component 3 includes a multifunctional film 301 attached to the photovoltaic panel body 2. One end of the multifunctional film 301 is wound and connected to a first... connected to the lower support frame 101. A first take-up member 302 is connected to a second take-up member 303 at the other end of a multifunctional film 301. The first take-up member 302 includes two first take-up frames 3021 connected to the lower support frame 101. A first take-up shaft 3022 is fitted between the two first take-up frames 3021. A first take-up roller 3023 is rotatably connected to the first take-up shaft 3022. Both ends of the first take-up roller 3023 are provided with torsion grooves 3024. A spring spring 3025 is fitted at both ends of the first take-up shaft 3022 corresponding to the two torsion grooves 3024. 2. The second winding member 303 includes two second winding frames 3031 connected to the lower support frame 101, which are elastically connected to the inner end faces of the two torsion grooves 3024 respectively by two spring springs 3025. The two second winding frames 3031 are rotatably connected to the same second winding shaft 3032. A second winding roller 3033 is mounted on the second winding shaft 3032. A gear 3034 is mounted on the second winding shaft 3032. A toothed plate 3035 meshes on the tooth surface of the gear 3034. An elbow 3036 is supported and connected between the toothed plate 3035 and the lower support frame 101.

[0046] The specific implementation method is as follows: The wing plate 4 is located in a well-ventilated position inside the lower support frame 101. The wing plate 4 adopts an airfoil design with a flat upper surface and a convex lower surface. The lower surface has a larger curvature, while the upper surface is relatively flat. This shape makes the path of air flowing over the wing plate 4 longer on the lower surface and shorter on the upper surface. According to Bernoulli's principle, the pressure is lower in areas with high airflow velocity and higher in areas with low airflow velocity. When strong winds flow over the wing plate 4, the wing plate 4 will generate a downward force. The wing plate 4 applies the downward force to the photovoltaic panel body 2 through the connecting shaft 5. On the one hand, the photovoltaic panel body 2 slides in the slide groove 1052 via the slider 1054 and undergoes elastic deformation based on the second spring 1055. On the other hand, the photovoltaic panel body 2 applies a downward force to the upper support frame 1051 via the slider 1054. The upper support frame 1051 sinks in the multiple lifting grooves 102 via multiple lifting shafts 103 and simultaneously squeezes multiple first springs 104 to cause elastic deformation, so that the photovoltaic panel body 2 can slide sideways and sink when subjected to the downward force.

[0047] Specifically, a pressing component 6 is connected to the photovoltaic panel body 2 corresponding to the multifunctional film 301. The pressing component 6 includes a right-angle frame 601 connected to the photovoltaic panel body 2. Multiple rotating shafts 602 are rotatably connected to the inner side of the right-angle frame 601. Each of the multiple rotating shafts 602 is fitted with a pressing wheel 603. The multiple pressing wheels 603 are rotatably connected to the multifunctional film 301.

[0048] The specific implementation method is as follows: the pressure roller 603 is used to press down the edge of the multifunctional film 301 so that the multifunctional film 301 is tightly attached to the photovoltaic panel body 2.

[0049] Specifically, a filter plate 8 is embedded in the port at the top of the water receiving hopper 7, a water receiving pipe 9 is connected to the bottom of the water receiving hopper 7, and a water storage tank 10 is connected to the other end of the water receiving pipe 9. The cleaning component 11 includes two adapter frames 1101 connected to the upper support frame 1051. A cleaning pipe 1102 is rotatably connected between the two adapter frames 1101. The outer wall of the cleaning pipe 1102 faces the multifunctional membrane 301 and has two sets of spray holes 1103. There are multiple spray holes 1103 in a single set, and the openings of the two sets of spray holes 1103 face both sides of the multifunctional membrane 301.

[0050] A piston cylinder 1104 is connected to the lower support frame 101. The piston rod of the piston cylinder 1104 is connected to the upper support frame 1051. A discharge pipe 1105 is connected to the piston cylinder 1104. The other end of the discharge pipe 1105 is connected to the cleaning pipe 1102. An inlet pipe is connected to the piston cylinder 1104. The other end of the inlet pipe is connected to the water storage tank 10. A one-way valve is installed on both the inlet pipe and the discharge pipe 1105.

[0051] The specific implementation method is as follows: After rainwater drips onto the multifunctional membrane 301, it flows into the water receiving hopper 7 along the inclined surface. The filter plate 8 can filter the rainwater flowing into the water receiving hopper 7. At the same time, the rainwater flowing into the water receiving hopper 7 can wash the inclined filter plate 8. The rainwater collected in the water receiving hopper 7 flows into the water storage tank 10 through the water receiving pipe 9. During the lifting and lowering movement of the upper support frame 1051 in the lifting groove 102 via the lifting shaft 103, it will drive the toothed plate 3035 to move downward on the tooth surface of the gear 3034 through the elbow 3036. Driven by the toothed plate 3035, the gear 3034 moves downward through the second winding shaft 3032 to the two second winding frames. Rotating between 3031, the second take-up roller 3033 rotates under the drive of the second take-up shaft 3032 to take up the multifunctional film 301. The multifunctional film 301 drives the first take-up roller 3023 to rotate and twists the spring spring 3025 to make it elastically deform. During this process, the upper support frame 1051 presses down the piston shaft of the piston cylinder 1104, the hydraulic pressure inside the piston cylinder 1104 increases, the one-way valve on the discharge pipe 1105 opens, and the rainwater in the piston cylinder 1104 flows into the cleaning pipe 1102 through the discharge pipe 1105, and finally sprays out towards both sides of the multifunctional film 301 through two sets of spray holes 1103 to rinse and clean the surface of the multifunctional film.

[0052] Working principle and usage:

[0053] The multifunctional membrane 301 combines the characteristics of both dustproof and self-cleaning membranes. The dustproof membrane focuses on the source of dust accumulation to reduce the amount of dust adsorption, while the self-cleaning membrane focuses on the cleaning efficiency of the photovoltaic panel body 2, enabling the photovoltaic panel body 2 to achieve better cleaning results with less water or rainwater. The function of the multifunctional membrane 301 is to reduce the physical adsorption or adhesion between dust and the surface of the photovoltaic panel body 2.

[0054] The wing plate 4 is located in a well-ventilated position inside the lower support frame 101. The wing plate 4 adopts an airfoil design with a flat upper surface and a convex lower surface. The lower surface has a larger curvature, while the upper surface is relatively flat. This shape makes the path of air flowing over the wing plate 4 longer on the lower surface and shorter on the upper surface. According to Bernoulli's principle, the pressure is lower in areas with high airflow velocity and higher in areas with low airflow velocity. When a strong wind flows over the wing plate 4, the wing plate 4 will generate a downward force. The wing plate 4 applies the downward force to the photovoltaic panel body 2 through the connecting shaft 5. On the one hand, the photovoltaic panel body 2 slides within the slide groove 1052 via the slider 1054. And based on the second spring 1055, it causes elastic deformation. On the other hand, the photovoltaic panel body 2 applies a downward force to the upper support frame 1051 through the slider 1054. The upper support frame 1051 sinks in the multiple lifting grooves 102 through multiple lifting shafts 103, and at the same time squeezes multiple first springs 104 to cause elastic deformation, so that the photovoltaic panel body 2 can slide sideways and sink when subjected to the downward force. Since the wind direction and wind force of the strong wind are different from those of the multiple wing plates 4, misalignment will occur between the photovoltaic panel bodies 2 that are arranged.

[0055] Rainwater drips onto the multifunctional membrane 301 and flows down the inclined surface into the water collection hopper 7. The filter plate 8 filters the rainwater flowing into the water collection hopper 7, and at the same time, the rainwater flowing into the water collection hopper 7 washes the inclined filter plate 8. The rainwater collected in the water collection hopper 7 flows into the water storage tank 10 through the water collection pipe 9. During the lifting and lowering movement of the upper support frame 1051 in the lifting groove 102 via the lifting shaft 103, it drives the toothed plate 3035 to move downward on the tooth surface of the gear 3034 through the elbow 3036. Driven by the toothed plate 3035, the gear 3034 rotates between the two second winding frames 3031 via the second winding shaft 3032. Driven by the second winding shaft 3032, the second winding roller 3033 rotates to wind up the multifunctional membrane 301. The multifunctional membrane 301 drives the first winding roller 3023 to rotate. The spring 3025 is twisted to cause elastic deformation. During this process, the upper support frame 1051 presses down the piston shaft of the piston cylinder 1104, the hydraulic pressure inside the piston cylinder 1104 increases, the one-way valve on the discharge pipe 1105 opens, and the rainwater in the piston cylinder 1104 flows into the cleaning pipe 1102 through the discharge pipe 1105. Finally, it is sprayed out towards both sides of the multifunctional membrane 301 through the two sets of spray holes 1103 to rinse and clean the surface of the multifunctional membrane. When the wind weakens, the photovoltaic panel body 2 rises under the action of the elastic restoring force of the first spring 104 and the second spring 1055. The one-way valve on the discharge pipe 1105 closes, and the one-way valve on the inlet pipe opens. The piston cylinder 1104 draws rainwater from the water storage tank 10 through the inlet pipe for subsequent use. The rainwater is used to clean the surface of the multifunctional membrane 301.
