Description

Technical Field

[0001] This invention relates to the field of photovoltaic power plant technology, specifically to a distributed photovoltaic power plant. Background Technology

[0002] Currently, photovoltaic power stations mainly convert light energy into electrical energy through photovoltaic modules and store the electrical energy. The photovoltaic modules are installed through photovoltaic brackets. At present, distributed photovoltaic power stations are mainly concentrated on rooftops, carports, building facades, and unused land around buildings. The characteristics of distributed photovoltaic power stations are that they require less material and have a smaller amount of engineering work.

[0003] Among the existing technologies, the distributed photovoltaic power station proposed in the patent announcement number CN221408716U includes a support frame, a frame assembly installed on the top of the support frame, and multiple photovoltaic panel assemblies installed on the top of the frame assembly. Multiple screws are threadedly connected to the support frame. A rotating ring is installed on the top of each screw, a drill bit is fixed to the bottom of each screw, and a limiting mechanism for limiting the screw is installed on the screw.

[0004] Existing technologies often employ fixed protective covers or lack effective protection, making the equipment susceptible to damage and shortening its lifespan in severe weather conditions such as rain, snow, and hail. The fixed or inaccurate tilt angle of photovoltaic panels prevents the maximization of solar resources, resulting in low power generation efficiency. The cleaning process typically relies on manual labor or requires multiple drive units, leading to low efficiency, high costs, and poor stability, failing to meet the operational requirements of high efficiency and low maintenance. Therefore, we propose a distributed photovoltaic power station. Summary of the Invention

[0005] The technical problem to be solved by this invention is to overcome the shortcomings of existing technologies and provide a distributed photovoltaic power station that automatically deploys to resist rain, snow and hail in severe weather, protects the equipment and extends its lifespan, and automatically retracts after sunny weather to avoid blocking sunlight. It optimizes the angle of the photovoltaic panels in real time to maximize the absorption of sunlight and improve power generation efficiency. A single motor synchronously completes cleaning and movement, and the self-locking design ensures stable operation. It significantly reduces the need for manual maintenance and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a distributed photovoltaic power station, comprising a base plate, a protection unit, an adjustment and support unit, and a cleaning unit;

[0007] Base plate: A protective unit and an adjustment and support unit are installed at the upper end, and a cleaning unit is installed at the upper end of the adjustment and support unit;

[0008] The protective unit comprises a dovetail-shaped slide, a threaded rod, a motor, a sliding frame, and a fixing plate. Two dovetail-shaped slides are formed on the upper left and right sides of the base plate. The inner front and rear ends of the right dovetail-shaped slide are rotatably connected to the outer front and rear ends of the threaded rod. The motor is fixedly connected to the rear right side of the base plate, and its output shaft is fixedly connected to the rear end of the threaded rod. A fixing plate is fixedly connected to the upper rear side of the base plate. The lower ends of the sliding frame are slidably connected to the inner sides of the two dovetail-shaped slides, and the lower end of the sliding frame is threadedly connected to the threaded rod. The protective unit controls the sliding frame to slide horizontally along the dovetail-shaped slides on both sides of the base plate by driving the threaded rod with the motor. The fixing plate provides rear-end support. The rotation of the threaded rod causes the sliding frame to translate within the limits of the dovetail slides. The motor provides power input, the dovetail structure prevents detachment, the dovetail slides ensure the stability of the sliding frame's movement, and the threaded transmission achieves precise displacement control, providing a mechanical basis for the extension and retraction of the protective cover.

[0009] Furthermore, the protective unit also includes a stacked silicone protective cover. The front and rear ends of the stacked silicone protective cover are fixedly connected to the outer sides of the sliding frame and the fixed plate. The surface of the stacked silicone protective cover is coated with a nano-hydrophobic coating, and the interior of the stacked silicone protective cover is embedded with aramid mesh fabric. The stacked silicone protective cover connects the sliding frame and the fixed plate, has a hydrophobic coating on its surface, and an aramid mesh fabric embedded inside. When the sliding frame moves, it stretches or compresses the stacked protective cover. The hydrophobic coating repels moisture, the aramid mesh fabric enhances tear resistance, the stretchable protective cover adapts to different deployment states, the hydrophobic and stain-resistant properties extend its lifespan, and the aramid structure improves mechanical strength, providing protection against weather conditions such as hail.

[0010] Furthermore, the adjustment and support unit includes a mounting frame, a second dovetail-shaped slide groove, a second threaded rod, and a second motor. The mounting frame is fixedly connected to the upper end of the base plate. A rotating shaft is fixedly connected to the inner front side of the mounting frame. The second dovetail-shaped slide groove is fixedly connected to the middle inner side of the mounting frame. The front and rear ends of the second dovetail-shaped slide groove are fixedly connected to the front and rear ends of the second threaded rod. The second motor is fixedly connected to the middle rear end of the mounting frame. The output shaft of the second motor is fixedly connected to one end of the second threaded rod. The mounting frame is fixed to the base plate, and its inner side is provided with the second dovetail-shaped slide groove and the second threaded rod. The second motor drives the threaded rod to rotate, causing the threaded rod to rotate within the dovetail slide groove, driving the sliding block to move horizontally. The dovetail slide groove design ensures transmission stability and provides a power source for adjusting the tilt angle of the photovoltaic panel.

[0011] Furthermore, the adjustment and support unit also includes connecting blocks, a rotating shaft, and a photovoltaic panel mounting frame. Two connecting blocks are fixedly connected to the lower left and right sides of the front end of the photovoltaic panel mounting frame. The inner side of the connecting blocks is rotatably connected to the outer side of the rotating shaft. The lower front end of the photovoltaic panel mounting frame is an inclined surface. The front end of the photovoltaic panel mounting frame is connected to the rotating shaft via connecting blocks, and the lower end is an inclined surface. The hinged structure allows the mounting frame to rotate around the shaft. The inclined surface matches the movement trajectory of the connecting rod, allowing for stepless tilt adjustment of the rotating shaft. The inclined surface also enables rapid guidance of water flow.

[0012] Furthermore, the adjustment and support unit also includes a connecting rod and a connecting fixing block. A connecting fixing block is fixedly connected to the middle of the lower rear end of the photovoltaic panel mounting frame. The inner side of the connecting fixing block is rotatably fixedly connected to the upper end of the connecting rod. A sliding block is slidably connected to the inner side of the dovetail-shaped slide groove two. The inner side of the sliding block is threadedly connected to the inner side of the threaded rod two. The lower end of the connecting rod is rotatably connected to the upper inner end of the sliding block. Driven by the threaded rod two, the sliding block moves along the dovetail slide groove two, pushing the rear end of the photovoltaic panel mounting frame to rise and fall through the connecting rod. The horizontal displacement of the sliding block causes the tilt angle of the connecting rod to change, which in turn causes the connecting fixing block to rise and fall, controlling the tilt angle of the photovoltaic panel mounting frame. The threaded transmission and four-bar linkage achieve precise angle adjustment, and the dovetail slide groove eliminates motion offset.

[0013] Furthermore, the cleaning unit includes a limiting groove, a sliding frame, and a mounting box. Two limiting grooves are formed on the left and right sides of the photovoltaic panel mounting frame. The left and right sides of the sliding frame are slidably connected to the inner sides of the limiting grooves. The mounting box is fixedly connected to the lower end of the sliding frame. The sliding frame is connected to the photovoltaic panel mounting frame via the limiting grooves on both sides, and the mounting box is fixed at the lower end. The sliding frame moves horizontally along the limiting grooves on the edge of the photovoltaic panel, causing the mounting box to cover the surface of the photovoltaic panel. The double-track limiting ensures the parallel movement of the cleaning components. The mounting box integrates the cleaning execution components.

[0014] Furthermore, the cleaning unit also includes a rotating shaft and a cleaning disc. Multiple rotating shafts are rotatably connected to the lower inner side of the mounting box, and the lower end of each rotating shaft is engaged with a cleaning disc. The rotating shaft, with the cleaning disc engaged at its lower end, is rotatably connected to the inside of the mounting box. The rotating shaft drives the cleaning disc to rotate and rub against the surface of the photovoltaic panel. The modular engagement design facilitates the replacement of the cleaning disc, and the multi-axis layout covers the cleaning area.

[0015] Furthermore, the cleaning unit also includes a worm gear, a worm, and a self-locking motor. A worm gear is fixedly connected to the upper end of the rotating shaft, and a worm is rotatably connected to the front inner side of the sliding frame. The worm engages with the worm gear. A self-locking motor is fixedly connected to the left end of the sliding frame, and the output shaft of the self-locking motor is fixedly connected to the left end of the worm. The worm gear is fixed to the upper end of the rotating shaft and meshes with the worm. The self-locking motor drives the worm to rotate, which in turn drives the worm gear to rotate. The rotating shaft drives the cleaning disc to rotate and rub against the surface of the photovoltaic panel. The self-locking characteristic of the worm gear prevents deviation during shutdown, and the high torque adapts to the conditions of stain cleaning.

[0016] Furthermore, the cleaning unit also includes gears and racks. Racks are fixedly connected to the upper left and right sides of the photovoltaic panel mounting frame, and two gears are fixedly connected to the outer left and right ends of the worm gear, meshing with the racks. Gears are fixed at both ends of the worm gear, meshing with the racks on both sides of the photovoltaic panel mounting frame. The worm gear rotates, and the gears roll along the racks, simultaneously driving the entire sliding frame to move horizontally. The gears and racks convert rotational motion into linear motion, synchronously driving the cleaning and walking functions.

[0017] Furthermore, it also includes threaded fixing blocks, photovoltaic panels, and light incident detectors. A photovoltaic panel is fixedly connected to the inner front end of the photovoltaic panel mounting frame, and a light incident detector is fixedly connected to the middle of the front end of the photovoltaic panel mounting frame. Four threaded fixing blocks are fixedly connected to the four corners of the lower end of the base plate. The threaded fixing blocks are installed at the four corners of the base plate, the photovoltaic panel is fixed to the inner side of the mounting frame, and the light incident detector is located at the middle of the front end. The threaded fixing blocks provide ground anchoring, the light detector monitors the incident angle of sunlight, and the four-point fixing ensures wind resistance stability. Real-time sunlight data assists in automatic tilt angle adjustment.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This distributed photovoltaic power station has the following advantages:

[0019] 1. This distributed photovoltaic power station uses a protective unit consisting of a layered silicone cover combined with an aramid-reinforced mesh. A motor-driven sliding mechanism enables rapid expansion and contraction of the cover. The surface features a nano-hydrophobic coating that actively repels rain and snow, while the internal aramid structure resists hail impacts. It automatically deploys to form a physical barrier in severe weather and retracts compactly when the weather clears. This dynamic protection mode significantly enhances the equipment's survivability in extreme environments while avoiding the continuous shading of sunlight caused by traditional fixed covers, thus extending the equipment's lifespan.

[0020] 2. This distributed photovoltaic power station uses a four-bar tilt adjustment mechanism based on real-time light detection to precisely control the tilt angle of the photovoltaic panels through threaded transmission, maximizing the capture of sunlight resources. The unique front-end inclined design simultaneously optimizes the rainwater diversion path, reducing the impact of water accumulation on power generation, and achieving simultaneous improvement in energy collection efficiency and environmental adaptability.

[0021] 3. In this distributed photovoltaic power station, when a single self-locking motor drives the worm gear to rotate, it simultaneously drives the cleaning disc to rotate at high speed to remove dirt. The entire cleaning frame is also propelled forward by the gears at both ends rolling along the rack on the side of the photovoltaic panel. The rotating brush disc efficiently removes surface dirt, while the gears roll along the rack on the edge of the photovoltaic panel, causing the entire cleaning component to move horizontally. The single motor synchronously drives the cleaning and walking actions, and the self-locking feature ensures operational stability and significantly reduces the need for manual maintenance.

The motor 44 drives the threaded rod 43 to move the sliding block 45 horizontally, and pushes the photovoltaic panel mounting frame 48 to adjust the tilt angle through the connecting rod 49. In case of severe weather such as hail or snow, the motor 33 of the protection unit 3 drives the threaded rod 32 to rotate.

Its aramid mesh reinforcement layer resists impact, and the nano-hydrophobic coating accelerates drainage. After the weather clears up, the sliding frame retracts and retracts the protective cover, compressing and storing it between the fixed plate 36 and the sliding frame. The linkage stacked silicone protective cover 35 can be unfolded or retracted to cope with severe weather. During cleaning, the self-locking motor 510 drives the worm gear 57 to rotate, and the gears 58 at both ends roll along the rack 59 to drive the sliding frame 52 to move horizontally.
