Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation, and specifically relates to a photovoltaic support device made of basalt composite material for tidal flats and its installation method. Background Technology

[0002] Solar photovoltaic (PV) power generation, as a form of clean energy utilization, has been widely applied in plains, mountainous areas, and some coastal regions. Common PV support structures are mostly made of metal materials such as steel and aluminum alloys, and are fixed to the ground or water surface via pile foundations to form a stable PV array structure. Regarding the cleaning of the PV panel surface, some installations are equipped with manual or simple electrically driven cleaning tools to ensure the light transmittance of the PV panel surface and maintain power generation efficiency. However, in environments with high salt spray, high humidity and heat, strong ultraviolet radiation, and strong winds, such as tidal flats and saline-alkali land, the adaptability and durability of traditional PV support structures and their cleaning devices are clearly insufficient.

[0003] Existing technologies have the following drawbacks in tidal flat environments: First, when metal supports are exposed to high salinity and humidity for extended periods, their surface passivation layer is easily damaged, leading to severe corrosion, a gradual decrease in structural strength, and a shortened service life. Second, strong winds in tidal flat areas can easily cause photovoltaic supports to loosen, tilt, or even collapse entirely, affecting the safe operation of the power station. Third, most existing cleaning devices rely on manual or electric operation, lacking automation and energy-saving design, making it difficult to promptly clean salt spray, dust, and bird droppings from the photovoltaic panel surface, resulting in decreased light transmittance, reduced power generation efficiency, and increased operation and maintenance costs. Therefore, existing technologies have not yet provided a support device and its installation method that can withstand harsh environmental corrosion and wind damage while automatically cleaning photovoltaic panels and ensuring power generation efficiency. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a photovoltaic support device made of basalt composite material for tidal flats, the support device comprising a photovoltaic panel, a cement pile, a support mechanism, and a cleaning mechanism.

[0005] The photovoltaic panel is connected to a plurality of linearly arranged purlins, which are mounted on a support plate. The support plate is connected to a cement pile via a support mechanism. The purlins and the support plate are made of basalt material.

[0006] The support mechanism includes a front support assembly and a rear support assembly, which are located on both sides of the cement pile. The photovoltaic panel is stabilized above the cement pile by the front support assembly and the rear support assembly.

[0007] The cleaning mechanism is installed between the photovoltaic panel and the support plate. The cleaning mechanism is used to clean the side of the photovoltaic panel facing the sun in order to improve the efficiency of photovoltaic power generation.

[0008] Furthermore, the front support assembly includes a front column and a front support rod. One end of the front column and the front support rod are rotatably connected to a connecting plate on the support plate, and the other end of the front column and the front support rod are connected to a locking assembly. The front column and the front support rod are made of basalt fiber composite material.

[0009] Furthermore, the rear support assembly includes a rear support rod and a rear column, one end of which is connected to a connecting plate on the support plate, and the other end of which is connected to a locking assembly.

[0010] Furthermore, the locking assembly includes two clamps arranged along the central axis of the cement pile, which are fixed to the cement pile by bolts. Two symmetrically arranged crossbeams are provided between the two clamps and are fixed to the cement pile by bolts. The ends of the front support rod and the rear support rod away from the support plate are connected to the clamps located below, and the ends of the front support rod and the rear support rod near the clamps are rotatably connected to the crossbeams. The ends of the front column and the rear column away from the support plate pass through the two clamps and are connected to the two clamps by bolts. The rear support rod and the rear column are made of basalt fiber composite material.

[0011] Furthermore, the support mechanism also includes two column top support rods, one end of which is rotatably mounted on a connecting plate located above the cement pile, and the other end of which is rotatably mounted on the connecting plates where the front column and the rear column are located, respectively. The clamps and connecting plates are made of basalt fiber composite material.

[0012] Furthermore, the cleaning mechanism includes a scraper with arc-shaped holes. The scraper is fixedly connected to a central shaft, which is rotatably mounted on a support plate. Blades and a rotating block are fixedly mounted on the central shaft. The rotating block has a spiral groove. A flexible brush is provided on the side of the scraper that contacts the photovoltaic panel. When wind blows and the blades rotate, the blades drive the central shaft to rotate, so that the central shaft drives the scraper to rotate and wipes the surface of the photovoltaic panel through the brush on the scraper.

[0013] Furthermore, the cleaning mechanism also includes a collection tank that passes through and is fixedly connected to the photovoltaic panel. The collection tank is fixedly connected to the support plate, and two sets of symmetrically arranged holes are provided inside the collection tank. Each set of holes includes a water inlet and a water outlet. The water inlet and water outlet are respectively connected to one end of the water inlet pipe and the water outlet pipe. The other end of the water inlet pipe and the water outlet pipe are connected to a water tank. The water outlet pipe is connected to a spray pipe located above the collection tank. Spray holes are provided at both ends of the spray pipe. The water tank is fixedly installed below the support plate. A piston plate is slidably installed inside the water tank. The piston plate is fixedly connected to a lifting rod. The lifting rod is slidably installed on the water tank. A return spring is provided between the lifting rod and the water tank. A protruding rod is fixedly installed on the end of the lifting rod away from the water tank. The protruding rod is slidably engaged with a spiral groove.

[0014] Furthermore, the cleaning mechanism also includes two symmetrically arranged drain pipes, one end of which is connected to a water tank and the other end of which is connected to a moving pipe. Both moving pipes are connected to water tanks and are slidably mounted on a guide plate.

[0015] Furthermore, the support device also includes two symmetrically arranged fan blades, which are rotatably mounted on the crossbeam. One end of a swing arm is connected to the fan blade, and the other end of the swing arm is rotatably connected to a slider on the guide plate. The slider is slidably engaged with the guide plate and is fixedly connected to the moving tube.

[0016] On the other hand, the present invention provides an installation method for a photovoltaic support device made of basalt composite material for tidal flats, comprising the following steps: S1: The cement piles are fixed to the mudflats by burying them, and the two clamps and the crossbeam are fixed to the cement piles with bolts.

[0017] S2: Based on the required angle of the photovoltaic panels, select the appropriate front column, front support rod, rear support rod, rear column, and column top support rod, and connect the front column, front support rod, rear support rod, rear column, and column top support rod to the clamps and crossbeams through connectors.

[0018] S3: Select an appropriate number of purlins, install the purlins linearly on the support plate, install the photovoltaic panels on the purlins, and then connect the support plate to the front column, front support rod, rear support rod, rear column and column top support rod through the connecting plate.

[0019] S4: Connect the cleaning unit between the photovoltaic panels and the cement pile.

[0020] The beneficial effects of this invention compared with the prior art are: (1) This invention uses a column, a front support rod, a rear support rod, a rear column and a column top support rod to fix the photovoltaic panel and the support plate stably on the cement pile, and makes the column, the front support rod, the rear support rod, the rear column and the column top support rod form multiple triangular structures, which improves the stability and firmness of the installation and extends the service life of the support device; (2) In this invention, the column, the front support rod, the rear support rod, the rear column and the column top support rod are made of basalt fiber composite material, which has excellent salt spray corrosion resistance and damp heat resistance in the tidal flat environment, and has a longer service life than traditional metal material brackets; moreover, the basalt fiber composite photovoltaic bracket profile has better UV resistance than metal materials in the tidal flat environment and can be used for a longer time in the tidal flat environment; (3) In this invention, by setting a cleaning mechanism, the photovoltaic panel can be automatically cleaned by a scraper to remove corrosive residues on the surface of the photovoltaic panel, thereby improving the service life and power generation efficiency of the photovoltaic panel.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example: Figures 1-10 The diagram shows a photovoltaic support device made of basalt composite material for tidal flats. The support device includes a photovoltaic panel 1, a cement pile 30, a support mechanism, and a cleaning mechanism. The photovoltaic panel 1 is connected to a plurality of linearly arranged purlins 2, which are mounted on a support plate 3. The support plate 3 is connected to the cement pile 30 through the support mechanism.

[0038] like Figure 1 , Figure 2 , Figure 9 As shown, the photovoltaic panel 1 and purlin 2 are connected together by a clamping block. The self-weight of the photovoltaic panel 1, as well as external loads such as wind, snow, and sand, are transferred to the purlin 2, and then to the cement pile 30 through the purlin 2 and the support mechanism, ensuring the stability and firmness of the entire support device. The purlin 2 is designed as a hollow structure, which reduces its self-weight. Furthermore, multiple purlins 2 can be selectively used as needed; the specific number of purlins 2 used can be selected by those skilled in the art based on actual requirements. The span of the purlin 2 is 1.5 meters to 4.0 meters, and the purlins 2 are spaced 1.4 meters apart. The purlin 2 can bear the self-weight of the photovoltaic panel and possible variable loads such as wind, snow, and sand. Under the pressure of the photovoltaic panel, the maximum deflection of the purlin 2 at its mid-span and far-end is ι / 250 (ι is the purlin overhang length or purlin span).

[0039] The support mechanism includes a front support assembly and a rear support assembly, which are located on both sides of the cement pile 30. The photovoltaic panel 1 is stabilized above the cement pile 30 by the front support assembly and the rear support assembly.

[0040] The front support assembly includes a front column 4 and a front support rod 5. One end of the front column 4 and the front support rod 5 are rotatably connected to the connecting plate 10 on the support plate 3, and the other end of the front column 4 and the front support rod 5 are connected to the locking assembly.

[0041] The rear support assembly includes a rear support rod 6 and a rear column 7. One end of the rear support rod 6 and the rear column 7 are connected to the connecting plate 10 on the support plate 3, and the other end of the rear support rod 6 and the rear column 7 are connected to the locking assembly.

[0042] The locking assembly includes two clamps 9 arranged along the central axis of the cement pile 30. The clamps 9 are fixed to the cement pile 30 by bolts. Two symmetrically arranged crossbeams are provided between the two clamps 9. The two crossbeams are fixed to the cement pile 30 by bolts. The ends of the front support rod 5 and the rear support rod 6 away from the support plate 3 are connected to the clamps 9 located below. The ends of the front support rod 5 and the rear support rod 6 near the clamps 9 are rotatably connected to the crossbeams. The ends of the front column 4 and the rear column 7 away from the support plate 3 pass through the two clamps 9 and are connected to the two clamps 9 by bolts.

[0043] like Figure 1 , Figure 7 , Figure 8 , Figure 10 As shown, during installation, two clamps 9 are fixed to the cement pile 30 with bolts, and then two crossbeams are fixed to the cement pile 30 with bolts, with the crossbeams located between the two clamps 9. Depending on the required angle of the photovoltaic panels 1, select appropriate lengths for the front column 4, front support rod 5, rear support rod 6, rear column 7, and column top support rod 8. Then, connect one end of the front column 4 and the front support rod 5 to the connecting plate 10 below the support plate 3 using bolts or pins. Simultaneously connect the front support rod 5 to the crossbeam and the clamps 9, and connect the front column 4 to the clamps 9 and the crossbeams using bolts. The rear support rod 6 and rear column 7 are connected to the front support rod 5 and front column 4 in the same way. Finally, after connecting the two column top support rods 8 to the front column 4 and rear column 7 respectively, connect the two column top support rods 8 to the connecting plate 10 on the cement pile 30.

[0044] In this embodiment, a positioning groove 29 can be provided on the connecting plate 10. Sliding rods adapted to the positioning groove 29 can be provided on the front column 4, front support rod 5, rear support rod 6, rear column 7 and column top support rod 8 connected to the connecting plate 10. The positioning groove 29 and the sliding rods are used to position the front column 4, front support rod 5, rear support rod 6, rear column 7 and column top support rod 8 and facilitate their installation.

[0045] It is worth noting that after the front column 4, front support rod 5, rear support rod 6, rear column 7 and column top support rod 8 are completed, the rear support rod 6, rear column 7 and support plate 3, as well as the front column 4, front support rod 5 and support plate 3, all form a triangular shape. Triangles have stability, which can greatly improve the stability and firmness of the photovoltaic panel 1 installation. Similarly, the two ends of the front column 4 and column top support rod 8, and the two ends of the rear column 7 and column top support rod 8 also form a triangle.

[0046] The support mechanism also includes two column top support rods 8. One end of the two column top support rods 8 is rotatably installed on the connecting plate 10 located above the cement pile 30, and the other end of the two column top support rods 8 is rotatably installed on the connecting plate 10 where the front column 4 and the rear column 7 are located, respectively.

[0047] In this embodiment, the purlin 2, support plate 3, front column 4, front support rod 5, rear support rod 6, rear column 7, and column top support rod 8 are made of basalt fiber composite material. The manufacturing process is a fiber composite material pultrusion process, in which continuous basalt fibers and a numerical matrix are formed through a mold with a designed cross-sectional shape, and then cured. Basalt fiber composite material itself has the characteristics of being lightweight, high-strength, and resistant to seawater and salt spray corrosion, making it more suitable for the construction of coastal photovoltaic power stations.

[0048] The basalt fiber used in the production of profiles is continuous basalt fiber and basil fiber chopped strand mat. The specifications of continuous fiber include, but are not limited to, BC13-4800 and BC17-4800. The specifications of chopped strand mat include, but are not limited to, 300g / m2 / 450g / m2. The fiber content of the profile is 65%-85%, for example, 65%, 68%, 70%, 71%, 75%, 80%, but not limited to the listed values. Other values ​​within the range are also applicable.

[0049] The resin matrix used in the production of profiles includes, but is not limited to, epoxy resin (including modified epoxy resin), unsaturated resin, vinyl resin, etc., with a resin content of 15%-35%, for example, 15%, 16%, 17%, 20%, 28%, 30%, but not limited to the listed values, and other values ​​within the range are also applicable.

[0050] The fillers used in the production of profiles include, but are not limited to, one or more of heavy calcium carbonate, light calcium carbonate, aluminum hydroxide, etc., and the filler content is 0%-15%, for example, it can be 0%, 2%, 4%, 6%, 14%, 15%, but is not limited to the listed values. Other values ​​within the range are also applicable.

[0051] The additives used in the production of profiles include, but are not limited to, UV stabilizers (including but not limited to one or more of benzotriazoles, benzophenones, and triazines) and anti-aging agents (including one or more of antioxidants, light stabilizers, and heat stabilizers). The amount of UV stabilizers added is 0.5%-1%, for example, 0.5%, 0.6%, or 0.9%, but not limited to the listed values; other values ​​within this range are also applicable. The amount of anti-aging agents added is 1%-5%, for example, 1%, 2%, 2.5%, 4%, or 5%, but not limited to the listed values; other values ​​within this range are also applicable.

[0052] In this embodiment, the resin matrix used to produce the clamp 9 and the connecting plate 10 includes, but is not limited to, epoxy resin, unsaturated resin, vinyl resin, etc., and the resin content is 35%-65%, for example, it can be 35%, 40%, 42%, 48%, 65%, but is not limited to the listed values, and other values ​​within the range are also applicable.

[0053] The fillers for the clamps 9 and connecting plates 10 used in the production of basalt fiber composite materials include, but are not limited to, one or more types of heavy calcium carbonate and light calcium carbonate, with a filler content of 0%-35%, for example, 0%, 10%, 12%, 25%, 27%, 35%, but not limited to the listed values, and other values ​​within the range are also applicable.

[0054] A cleaning mechanism is installed between the photovoltaic panel 1 and the support plate 3. The cleaning mechanism is used to clean the side of the photovoltaic panel 1 facing the sun in order to improve the power generation efficiency of the photovoltaic panel 1.

[0055] The cleaning mechanism includes a scraper 11 with an arc-shaped hole 12. The scraper 11 is fixedly connected to a central shaft 13, which is rotatably mounted on a support plate 3. A blade 31 and a rotating block 14 are fixedly mounted on the central shaft 13. A spiral groove 15 is provided on the rotating block 14. A flexible brush is provided on the side of the scraper 11 that contacts the photovoltaic panel 1. When the wind blows the blade 31 to rotate, the blade 31 drives the central shaft 13 to rotate, so that the central shaft 13 drives the scraper 11 to rotate and wipes the surface of the photovoltaic panel 1 through the brush on the scraper 11.

[0056] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, when the wind blows the blades 31, the blades 31 will drive the central shaft 13 to rotate. At this time, the scraper 11, which is fixedly connected to the central shaft 13, will also rotate. The brush on the scraper 11 will clean the dust, frost, snow, etc. on the surface of the photovoltaic panel 1, thereby improving the power generation efficiency of the photovoltaic panel 1. The scraper 11 is provided with arc-shaped holes 12. During the rotation of the scraper 11, the arc-shaped holes 12 on the scraper 11 allow the water spray pipe 22 to pass through, that is, the rotation of the scraper 11 will not be interfered with by the water spray pipe 22.

[0057] The cleaning mechanism also includes a collection tank 21, which passes through and is fixedly connected to the photovoltaic panel 1. The collection tank 21 is fixedly connected to the support plate 3, and has two sets of symmetrically arranged holes inside. Each set of holes includes a water inlet and a water outlet. The water inlet and water outlet are respectively connected to one end of the water inlet pipe 19 and the water outlet pipe 20. The other ends of the water inlet pipe 19 and the water outlet pipe 20 are connected to the water tank 18. The water outlet pipe 20 is connected to the water spray pipe 22 located above the collection tank 21. The water spray pipe 22 has spray holes at both ends. The water tank 18 is fixedly installed below the support plate 3. A piston plate is slidably installed inside the water tank 18. The piston plate is fixedly connected to the lifting rod 16. The lifting rod 16 is slidably installed on the water tank 18. A return spring 17 is provided between the lifting rod 16 and the water tank 18. A protruding rod is fixedly installed on the end of the lifting rod 16 away from the water tank 18. The protruding rod is slidably engaged with the spiral groove 15.

[0058] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the collection tank 21 is used to collect rainwater and frost and snow that can melt into water. The collected water will enter the water tank 18 for storage through the water inlet and outlet holes, as well as the water inlet pipe 19 and the water outlet pipe 20. Of course, if a lot of water is collected, the water will enter the moving pipe 24 and the water tank 25 for storage through the drain pipe 23.

[0059] A one-way valve is installed between the water inlet pipe 19 and the collection tank 21, meaning that water in the collection tank 21 can flow into the water tank 18 through the water inlet pipe 19, but water in the water tank 18 will not enter the collection tank 21 through the water inlet pipe 19.

[0060] When the central shaft 13 rotates, the rotating block 14 fixed on the central shaft 13 will also rotate, and the spiral groove 15 will rotate relative to the protrusion on the lifting rod 16. The spiral groove 15 is spiral-shaped, so during the rotation of the rotating block 14, the lifting rod 16 will slide up and down relative to the water tank 18, thereby causing the piston plate to slide back and forth. The piston plate will press the water in the water tank 18 into the water spray pipe 22 through the water outlet pipe 20, and spray it onto the photovoltaic panel 1 through the spray holes at both ends of the water spray pipe 22, so that the scraper 11 can clean the surface of the photovoltaic panel 1.

[0061] In this embodiment, the function of the return spring 17 is to assist the return of the lifting rod 16. In addition, with the movement of the piston plate, the water stored in the moving pipe 24 and the water tank 25 can be pumped into the water tank 18 through the drain pipe 23.

[0062] The cleaning mechanism also includes two symmetrically arranged drain pipes 23. One end of the drain pipe 23 is connected to the water tank 18, and the other end of the drain pipe 23 is connected to the moving pipe 24. Both moving pipes 24 are connected to water tanks 25, and the moving pipes 24 are slidably mounted on the guide plate 28.

[0063] The support device also includes two symmetrically arranged fan blades 27, which are rotatably mounted on the crossbeam. One end of a swing rod 26 is connected to the fan blade 27, and the other end of the swing rod 26 is rotatably connected to a slider on the guide plate 28. The slider is slidably engaged with the guide plate 28, and the slider is fixedly connected to the moving tube 24.

[0064] like Figure 1 , Figure 2 , Figure 7 As shown, when there is wind, the wind will blow the fan blade 27 to rotate on the crossbeam. The rotation of the fan blade 27 will drive the swing arm 26 to rotate. The swing arm 26 will drive the slider to slide on the guide plate 28. At the same time, the moving tube 24 and the water tank 25 will also slide and move. The swing arm 26 is a telescopic structure.

[0065] In this embodiment, a damping structure is provided at the connection between the fan blade 27 and the crossbeam, and the contact between the slider and the guide plate 28 is also a frictional contact, that is, the slider and the fan blade 27 will not move easily. The purpose of this is to improve the wind resistance of the entire support device and improve the stability and firmness of the support device. In addition, if the moving pipe 24 and the water tank 25 are in the state of storing water, the stability and firmness can be further improved.

[0066] This invention also discloses an installation method for a photovoltaic support device made of basalt composite material used in tidal flats, comprising the following steps: S1: The cement pile 30 is fixed to the mudflat by burying, and the two clamps 9 and the crossbeam are fixed to the cement pile 30 by bolts.

[0067] S2: Based on the required angle of the photovoltaic panels 1, select the appropriate front column 4, front support rod 5, rear support rod 6, rear column 7 and column top support rod 8, and connect the front column 4, front support rod 5, rear support rod 6, rear column 7 and column top support rod 8 to the clamp 9 and crossbeam through connectors.

[0068] S3: Select an appropriate number of purlins 2, install the purlins 2 linearly on the support plate 3, install the photovoltaic panel 1 on the purlins 2, and then connect the support plate 3 to the front column 4, front support rod 5, rear support rod 6, rear column 7 and column top support rod 8 through the connecting plate 10.

[0069] S4: Connect the cleaning mechanism between the photovoltaic panel 1 and the cement pile 30.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
