Technical Field

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

The photovoltaic power generation and energy storage conversion device is provided with a mounting frame, and the mounting frame is set as a U-shaped structure, so that the mounting rods on both sides of the cleaning roller can move in the middle of the mounting frame, thereby increasing the convenience of daily cleaning of the upper end of the solar photovoltaic panel. At the same time, the screw rod and the mounting rod are threadedly connected. When the screw rod is driven by the motor to rotate the transmission rod, the positioning bolt can be passed through the assembly plate and the mounting frame to fix them together to prevent the screw rod from shaking due to external influences.

[0027] like Figure 1-Figure 4As shown, a photovoltaic energy storage conversion device proposed by the utility model includes a bracket 1, a driving component 4, a rack 8, a slider 9, a protective cover 11, a transmission component 13 and a control component. The bracket 1 is rotatably connected to a frame 3, a photovoltaic panel 301 is arranged on the frame 3, and dust discharge holes 302 are arranged on both sides of the photovoltaic panel 301 on the frame 3; a vertical pole 2 is arranged on the bracket 1, a fixing seat A is arranged at the bottom of the frame 3, the fixing seat A is rotatably connected to a rotating shaft A, and the rotating shaft A is rotatably connected to the vertical poles 2 on both sides. A reinforcing plate for improving the stability of the vertical pole 2 is tiltedly arranged on the bracket 1. The driving component 4 is connected to the bracket 1 and drives the frame 3 to flip to adjust the pitch angle of the photovoltaic panel 301; the driving component 4 includes but is not limited to a hydraulic cylinder; a fixed shaft is set between the two side vertical poles 2, the cylinder barrel of the hydraulic cylinder is rotatably connected to the fixed shaft, and the outer end of the push rod of the hydraulic cylinder is rotatably set with a rotating shaft B, and the rotating shaft B is rotatably connected to the fixed seat B, and the fixed seat B is connected to the bottom of the frame 3. The rack 8 is connected to the bottom surface of the frame 3, and the convex teeth of the rack 8 face downward, and a sliding rod 7 parallel to the rack 8 is set at the bottom of the frame 3; two downward-opening slide grooves 303 are set in parallel on the frame 3, and the slide groove 303 is perpendicular to the ash discharge hole 302, and the sliding rod 7 and the rack 8 are both located in the slide groove 303, wherein the downward-opening slide groove 303 can effectively prevent the gear 10 and the rack 8 from being eroded by rainwater, thereby extending their service life. The slider 9 is slidably connected with the slide bar 7, and the slider 9 is rotatably connected with the gear 10, and the gear 10 is meshed with the rack 8; the protective cover 11 is connected with the sliders 9 on both sides, and the protective cover 11 is suspended above the frame 3, and the cleaning roller 12 is rotatably arranged inside the protective cover 11, and the cleaning roller 12 is in flexible contact with the frame 3 and the photovoltaic panel 301; the transmission assembly 13 is located in the slider 9 and is transmission-connected with the gear 10 and the cleaning roller 12. The transmission assembly 13 includes a sprocket A, a sprocket B and a chain, and the outer diameter of the sprocket A is greater than the outer diameter of the sprocket B; the slider 9 is rotatably connected with the rotating shaft C, the rotating shaft C is connected with the gear 10, the sprocket A is connected with the rotating shaft C, the sprocket B is connected with the roller shaft of the cleaning roller 12, and the chain transmission connects the sprocket A and the sprocket B. The control assembly includes a timer switch and a controller, the controller is electrically connected with the timer switch, and the timer switch is electrically connected with the hydraulic cylinder.

[0028] In this embodiment, the controller is first used to set the start time interval of the time switch and the telescopic length of the hydraulic cylinder to adjust the light angle of the photovoltaic panel 301 at an appropriate time node, so that the photovoltaic panel 301 receives light at a better angle, thereby improving the photovoltaic power generation efficiency. For example, when the sun rises and before the sun sets, the light angle deviation is large. At this time node, the hydraulic cylinder is started, and the hydraulic cylinder drives the frame 3 to flip so that the photovoltaic panel 301 faces the sun. At this time, due to the gradual inclination of the frame 3, the slider 9 and the protective cover 11 slide down under the action of gravity. During the sliding process of the slider 9, the gear 10 rolls along the rack 8, and its rolling direction is opposite to its moving direction. Since the gear 10 and the cleaning roller 12 are driven by the sprocket and the chain, the rotation direction of the cleaning roller 12 is consistent with the rotation direction of the gear 10, but its rotation speed is higher than the rotation speed of the gear 10. The cleaning roller keeps rotating during the sliding process of the protective cover 11, and sweeps the dust and other debris on the photovoltaic panel 301 in the moving direction of the protective cover 11 until the dust and other impurities are discharged from the dust discharge hole 302. The cleaning structure is automatically completed when the angle of the photovoltaic panel 301 changes, and there is no need to set a separate program or start it with power consumption, and the structure is simple.
