Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic support component for desert areas with adjustable angle. Background Technology

[0002] Photovoltaic brackets are specialized structures used to fix and support photovoltaic modules in solar photovoltaic power generation systems, ensuring that photovoltaic panels can be installed stably and receive sunlight at the optimal angle. In desert areas, the tilt angle of traditional fixed brackets remains unchanged throughout the year, which cannot match the difference in solar altitude angle between winter and summer. By adjusting the angle, the power generation can be significantly improved. Therefore, a photovoltaic bracket module with an adjustable angle for desert areas is used. To this end, patent CN217590673U discloses a flexible photovoltaic support system suitable for tidal flats and desert areas, comprising: a rectangular frame; an adjustment mechanism on the rectangular frame, on which a solar panel is fixed, the adjustment mechanism being used to adjust the tilt angle of the solar panel; a stabilizing mechanism at the bottom of the rectangular frame for stabilizing the rectangular frame; the adjustment mechanism including two sets of parallel sub-adjustment mechanisms; a slide rail with several equidistant mounting holes, a slider sliding on the slide rail, the slider having screw holes adapted to the mounting holes; one end of a first connecting arm hinged to the slider, the other end of the first connecting arm hinged to one end of a second connecting arm, the other end of the second connecting arm hinged to a fixing block, the fixing block being disposed on the rectangular frame, bolts inserted into the screw holes and mounting holes to fix the slider on the slide rail; and the solar panel being fixed on two second connecting arms. This utility model achieves adjustment of the solar panel angle, which is beneficial to improving the conversion efficiency of sunlight. While the aforementioned flexible photovoltaic support system suitable for tidal flats and desert areas is beneficial for improving the conversion efficiency of sunlight, its applicability is limited due to the difficulty in cleaning it, removing accumulated sand and dust from the photovoltaic panel surface, and addressing the problem of power generation efficiency degradation in windy and sandy environments. Utility Model Content

[0003] The purpose of this invention is to provide an angle-adjustable photovoltaic support assembly for desert areas, in order to solve the problem that existing angle-adjustable photovoltaic support assemblies for desert areas are inconvenient to clean.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an angle-adjustable photovoltaic support assembly for desert areas, including a fixing plate; A solar photovoltaic panel is embedded at the top of the fixing plate, a storage battery is installed at the bottom of the fixing plate, and an adjustment structure is fixed on both sides of the bottom of the fixing plate. Cleaning structures are provided on both sides of the fixing plate; The cleaning structure includes a first fixing frame fixed to one side of a fixing plate, and a second fixing frame fixed to the other side of the fixing plate. A threaded rod is provided inside the first fixing frame, and a movable seat is threadedly connected to the outer side of the threaded rod. A support rod is fixed inside the second fixing frame, and a movable seat is sleeved on the outer side of the support rod. A top plate is provided above the fixing plate, and a second electric push rod passes through the inside of the top plate. A movable plate is fixed to the bottom end of the second electric push rod, and a scraper is fixed to the bottom end of the movable plate.

[0005] Preferably, the adjustment structure includes a fixed frame, a first electric push rod, a guide rod, a support body, a hinge seat, a fixed rod, and a slide. The fixed frame is located on one side below the fixed plate, and the support body is located on the other side below the fixed plate. Hinges are hinged to both sides of the top of the support body. The first electric push rod passes through the top of the fixed frame, and a slide is hinged to the top of the first electric push rod. Fixed rods are evenly distributed throughout the interior of the slide, and guide rods pass through the interior of the fixed frame on both sides of the first electric push rod. When the first electric push rod moves the slide, the slide slides outside the fixed rod, and simultaneously, the slide drives the guide rod to slide inside the fixed frame. Under the guidance of the guide rod and the fixed rod, the stability of the slide during movement is enhanced. After moving, the slide drives the fixed plate to move via the fixed rod, causing the fixed plate to rotate the hinge seat at the top of the support body, thereby changing the angle of the solar photovoltaic panel.

[0006] Preferably, the guide rod and the fixing frame form a sliding structure. The top end of the guide rod is hinged to the bottom end of the slide block, and the top end of the hinge block is fixedly connected to the bottom end of the fixing plate. Connecting plates are fixed to both ends of the fixing rod, and the fixing rod is fixedly connected to the bottom end of the fixing plate through the connecting plates. The slide block and the fixing rod constitute a sliding structure. When the fixing plate is raised, the tilt angle of the solar photovoltaic panel increases, maximizing sunlight reception in winter. When the fixing plate is leveled, the tilt angle of the solar photovoltaic panel decreases, reducing the windward area and wind load impact during sandstorms and strong winds.

[0007] Preferably, a protective layer is provided on the outer side of the scraper, connecting seats are fixed on both sides of the bottom end of the top plate, movable rods penetrate through the interior of the top plates on both sides of the second electric push rod, a servo motor is installed at one end of the first fixed frame, and protective curtains are fixed on both sides of the bottom of the movable seat and the movable seat. Activating the second electric push rod causes the movable plate to extend and retract, and the movable plate causes the movable rod to slide inside the top plate. Under the action of the movable rod, the stability of the movable plate during movement is enhanced. After moving, the movable plate causes the scraper to descend, so that the bottom end of the scraper is tightly attached to the surfaces of the solar photovoltaic panel, the fixed plate, the first fixed frame, and the second fixed frame.

[0008] Preferably, the movable rod and the top plate form a sliding structure. The bottom end of the movable rod is fixedly connected to the top end of the movable plate. The protective layer is actually an antistatic superhydrophobic composite coating. The bottom ends of the movable seat and the moving seat extend to the outside of the first fixed frame and the second fixed frame, respectively, and are fixedly connected to the bottom of the connecting seat. The servo motor is started, causing the threaded rod to rotate. The threaded rod drives the moving seat to move, and the moving seat drives the top plate to move through the connecting seat. Simultaneously, the top plate drives the movable seat to move outside the support rod through the connecting seat.

[0009] Preferably, one end of the threaded rod extends to the outside of the first fixed frame and is fixedly connected to the output end of the servo motor, while the other end extends to the inside of the first fixed frame and forms a rotating structure with the first fixed frame. The side of the protective curtain away from the movable seat and the moving seat is fixedly connected to the inner walls of the first and second fixed frames, respectively. The movable seat and the support rod form a sliding structure. Under the action of the protective curtain, sand and dust are prevented from entering the interior of the first and second fixed frames. The moved top plate will drive the scraper to uniformly scrape the surfaces of the solar photovoltaic panel, the fixed plate, the first fixed frame, and the second fixed frame. The protective layer is actually an antistatic superhydrophobic composite coating. Under the action of the protective layer, it can prevent the electrostatic adsorption and adhesion of desert fine sand to the scraper, thereby solving the problem of power generation efficiency degradation in windy and sandy environments.

[0010] Preferably, the output end of the solar photovoltaic panel is electrically connected to the input end of the battery through a photovoltaic controller.

[0011] The present invention provides an adjustable-angle photovoltaic support module for desert areas, the advantages of which are: By incorporating a cleaning structure, when the second electric push rod drives the movable plate to extend or retract, the stability of the movable plate during movement is enhanced under the action of the movable rod. After moving, the movable plate drives the scraper to descend, ensuring that the bottom end of the scraper tightly adheres to the surfaces of the solar photovoltaic panel, the fixed plate, the first fixed frame, and the second fixed frame. When the movable seat moves outside the threaded rod, the movable seat drives the top plate to move through the connecting seat. Simultaneously, the top plate drives the movable seat to move outside the support rod through the connecting seat. Under the action of the protective curtain, sand and dust are prevented from entering the interior of the first and second fixed frames. After moving, the top plate drives the scraper to uniformly scrape the surfaces of the solar photovoltaic panel, the fixed plate, the first fixed frame, and the second fixed frame. Under the action of the protective layer, it can prevent the electrostatic adsorption and adhesion of desert fine sand to the scraper, thereby solving the problem of power generation efficiency degradation in windy and sandy environments. With an adjustable structure, when the first electric push rod moves the slide block, the slide block slides on the outside of the fixed rod. At the same time, the slide block moves the guide rod inside the fixed frame. Under the guidance of the guide rod and the fixed rod, the stability of the slide block during movement is enhanced. After moving, the slide block moves the fixed plate through the fixed rod, causing the fixed plate to rotate the hinge seat on the top of the bracket body. This changes the angle of the solar photovoltaic panel. When the fixed plate is raised, the tilt angle of the solar photovoltaic panel increases, maximizing the reception of sunlight in winter. When the fixed plate is flat, the tilt angle of the solar photovoltaic panel decreases, reducing the windward area and wind load impact during sandstorms and strong winds.
