Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to a stacked-wing photovoltaic power generation and energy storage device. Background Technology

[0002] Photovoltaics, or photovoltaic power generation systems, are power generation systems that utilize the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy source of photovoltaic power generation systems is inexhaustible.

[0003] Patent CN219436936U discloses a solar power generation device, particularly a foldable photovoltaic panel. It includes a storage box; a detachable cover at the top and a base and movable parts at the bottom, with a storage chamber inside; a motor at the bottom of the storage chamber; a lead screw on the motor's main shaft; a lifting frame threaded onto the lead screw; mounting frames on both sides; a rotating groove on one side of the mounting frame, with the photovoltaic panel at its center; the lifting frame extends into the rotating groove and is rotatably connected to the mounting frame. This invention uses the rotation of the lead screw to raise the lifting frame. The mounting frames simultaneously move to the top of the storage chamber, allowing the photovoltaic panel to unfold. The photovoltaic panel is easy to store and move, improving the compactness, functionality, and flexibility of the structure, facilitating solar energy collection in the field. While this device solves the aforementioned problems, it still presents the challenge of cleaning and protecting the photovoltaic power generation device. Therefore, a stacked-wing photovoltaic power generation and energy storage device is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a stacked-wing photovoltaic power generation and energy storage device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a stacked-wing photovoltaic power generation and energy storage device, including a photovoltaic panel, a protective shell rotatably connected to the front of the photovoltaic panel, an angle adjustment mechanism provided at the bottom of the photovoltaic panel, the photovoltaic panel including a fixing block, a shaft, a gear, a rack, a locking strip, and a positioning groove, the fixing block being disposed at the rear of the photovoltaic panel, the shaft being rotatably connected inside the fixing block, the gear being fixedly connected to the outer circumferential surface of the shaft, the rack being fixedly connected to the outer surface of the photovoltaic panel, and the locking strip being fixedly connected to the photovoltaic panel. At the rear, the positioning groove is formed at the front of the fixing block. A motor is located on the right side of the shaft. The photovoltaic panel also includes a brush strip, a bevel gear, a limiting block, a limiting groove, and a limiting rod. The brush strip is fixedly connected to the bottom of the photovoltaic panel. The bevel gear is fixedly connected to the front of the shaft. The limiting block is located at the front of the photovoltaic panel. The limiting groove is formed at the rear of the limiting block. The limiting rod is fixedly connected to the front of the photovoltaic panel. The gear meshes with the rack. The locking strip is slidably connected to the inner wall of the positioning groove. The brush strip contacts the surface of the photovoltaic panel. The limiting rod... The rod slides along the inner wall of the limiting groove. When the device is placed at the bottom of the sun, the motor starts and drives the shaft to rotate. The rotation of the shaft drives the gear to rotate, and the gear meshes with the rack, causing the photovoltaic panel to slide and unfold. At this time, the locking strip slides inside the positioning groove under the translational movement of the photovoltaic panel. When the photovoltaic panel is fully unfolded, the locking strip stops moving inside the positioning groove, providing support for the photovoltaic panel and preventing it from shaking during operation, thus avoiding damage to the device. After the photovoltaic panel is unfolded, the contact area between the photovoltaic panel and sunlight can be greatly increased, increasing the power generation efficiency of the photovoltaic panel. When the device needs to be retracted, the drive motor reverses, and the shaft drives the gear to reverse. At this time, the three photovoltaic panels are stacked together, which facilitates the movement of the photovoltaic panels and saves the space required for the photovoltaic panels when idle. When the photovoltaic panel is unfolded or retracted, the gear meshes with the rack, causing the photovoltaic panel to move horizontally. At this time, the outer surface of the photovoltaic panel will make full contact with the brush strip, removing impurities from the surface of the photovoltaic panel and preventing excessive accumulation of impurities from affecting the working efficiency of the photovoltaic panel. It also saves the cost of manual cleaning.

[0006] Preferably, the angle adjustment mechanism includes a base, a track column, a helical rod, a device plate, a plate, an L-shaped rod, a slide block, a crank rod, a slider, and a positioning block. The L-shaped rod is rotatably connected to the bottom of the limiting block, the slider is slidably connected to the outer surface of the L-shaped rod, the crank rod is rotatably connected to the outer wall of the slider, the positioning block is rotatably connected to the outer wall of the crank rod, the plate is fixedly connected to the rear of the positioning block, the track column is fixedly connected to the rear of the plate, the device plate is slidably connected to the circumferential surface of the track column, the slide block is fixedly connected to the top of the device plate, and the helical rod is rotatably connected to the plate. Inside the device, the base is fixedly connected to the rear of the track column. The angle adjustment mechanism also includes a roller brush, a lubrication chamber, a protrusion, a spring, an oil groove, and an oil inlet. The roller brush is fixedly connected to the rear of the device plate, the lubrication chamber is fixedly connected to the front of the device plate, the protrusion is slidably connected to the inner wall of the lubrication chamber, the oil groove is opened on the outer wall of the protrusion, one end of the spring is fixedly connected to the top of the protrusion, the other end of the spring is fixedly connected to the inner wall of the top of the lubrication chamber, the oil inlet is opened on the top of the lubrication chamber, the protrusion contacts the screw rod, and the device plate is movably connected to the outer circumference of the screw rod. On the surface, the roller brush contacts the spiral rod, and the fixing block is fixedly connected to the top of the L-shaped rod. When the photovoltaic panel needs to find an angle with the largest contact area with sunlight, the motor at the rear of the spiral rod drives the spiral rod to rotate, causing the device plate to move. The movement of the device plate causes the slide block on the top of the device plate to move, and the movement of the slide block simultaneously drives the L-shaped rod to move. Simultaneously, the movement of the L-shaped rod drives the crank rod and the slider to perform circular motion, causing the slider to slide on the outer wall of the L-shaped rod, thus driving the photovoltaic panel to perform circular motion and achieving the effect of adjusting the angle of the photovoltaic panel. While the device plate moves, it also drives... The movement of the lubrication chamber causes the protrusion to move as well. When the protrusion slides into the spiral groove of the auger, the spring force is released, driving the protrusion to move downwards. At the same time, the oil groove moves downwards, and the lubricating oil inside the lubrication chamber drips down the oil groove onto the surface of the auger, providing lubrication and preventing rust from forming on the auger during long-term storage, which would affect the normal operation of the device. Simultaneously, the movement of the device plate causes the roller brush to roll back and forth on the surface of the auger, cleaning the surface of the auger and evenly spreading the lubricating oil dripping from the lubrication chamber for better lubrication.

[0007] Preferably, the protective shell includes a protective plate, a reflective surface, a second bevel gear, and a rotating rod. The rotating rod is fixedly connected to both ends of the limiting block. The protective plate is rotatably connected to the outer circumferential surface of the rotating rod. The second bevel gear is fixedly connected to the inner wall of the protective plate. The reflective surface is fixedly connected to the inner wall of the protective shell. The protective shell also includes a limiting groove, a limiting circle, a first support rod, a supporting spiral rod, a limiting triangle, and a fixing strip. The limiting groove is fixedly connected to the outer wall of the plate. The limiting circle is slidably connected to the inner wall of the limiting groove. The first support rod is fixedly connected to the outer circumferential surface of the limiting circle. The supporting spiral rod is threadedly rotatably connected to the inner wall of the first support rod. The limiting triangle is fixedly connected to the top of the supporting spiral rod. The fixing strip is fixedly connected to the bottom outer wall of the protective plate. The second bevel gear meshes with the first bevel gear. The limiting triangle contacts the fixing strip. When the photovoltaic panel unfolds, the shaft rotates, driving bevel gear one to rotate. At this time, bevel gear one meshes with bevel gear two, driving the protective plate to rotate and unfold. At this time, the reflective surface inside the protective plate comes into contact with sunlight, and the protective plate and the photovoltaic panel are at a certain angle, reflecting the sunlight falling on the reflective surface onto the surface of the photovoltaic panel, achieving the effect of concentrating light and improving the power generation efficiency of the photovoltaic panel. At this time, by manually unfolding the support rod one and rotating the support screw rod, the limiting triangle block is locked at the bottom of the fixing strip at a suitable height, which plays a supporting role for the protective shell. At the same time, the angle of the reflective surface can be adjusted by multiple fixing strips. When the device is retracted, the shaft drives bevel gear one to reverse, meshing with bevel gear two to drive the protective plate to rotate, thereby covering the top of the photovoltaic panel, so that the photovoltaic panel can be covered and protected when it is not in use.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This stacked-wing photovoltaic power generation and energy storage device, through the cooperation of photovoltaic panels, gears, transmission racks, and brushes, enables the photovoltaic panels to move horizontally when they are unfolded or retracted. At this time, the outer surface of the photovoltaic panel will make full contact with the brushes, removing impurities from the surface of the photovoltaic panel and preventing excessive accumulation of impurities from affecting the working efficiency of the photovoltaic panel. It also saves the cost of manual cleaning.

[0009] 2. In this stacked-wing photovoltaic power generation and energy storage device, with the cooperation of springs, protrusions, screw rods, and oil grooves, when the protrusions slide into the screw grooves of the screw rods, the spring force is released, driving the protrusions to move downwards. At the same time, the oil grooves move downwards, and the lubricating oil inside the oil tank drips down the oil grooves onto the surface of the screw rods, which lubricates the screw rods and prevents rust from forming on the screw rods when the device is not used for a long time, thus affecting the normal operation of the device.

[0010] 3. In this stacked-wing photovoltaic power generation and energy storage device, with the cooperation of the rotating shaft, bevel gear one, bevel gear two, and photovoltaic panel, when the device is retracted, the rotating shaft drives bevel gear one to reverse, and the meshing transmission bevel gear two drives the protective plate to rotate, thereby covering the top of the photovoltaic panel, so that the photovoltaic panel can be covered and protected when it is idle and not in use.

The retaining strip 106 is slidably connected to the inner wall of the positioning groove 107. The brush strip 105 contacts the surface of the photovoltaic panel 1. The limiting rod 111 is slidably connected to the inner wall of the limiting groove 110. The angle adjustment mechanism 2 includes a base 201, a track column 202, a helical rod 203, a device plate 204, a plate 205, an L-shaped rod 206, a slide block 207, a curved rod 208, a slider 209, and a positioning block 211. The L-shaped rod 206 is rotatably connected to the bottom of the limiting block 109, the slider 209 is slidably connected to the outer surface of the L-shaped rod 206, the curved rod 208 is rotatably connected to the outer wall of the slider 209, the positioning block 211 is rotatably connected to the outer wall of the curved rod 208, the plate 205 is fixedly connected to the rear of the positioning block 211, the track column 202 is fixedly connected to the rear of the plate 205, the device plate 204 is slidably connected to the circumferential surface of the track column 202, the slide block 207 is fixedly connected to the top of the device plate 204, the helical rod 203 is rotatably connected to the inside of the plate 205, and the base 201 is fixedly connected to the track column. At the rear of 202, the angle adjustment mechanism 2 also includes a roller brush 210, a lubrication chamber 212, a protrusion 213, a spring 214, an oil groove 215, and an oil inlet 216. The roller brush 210 is fixedly connected to the rear of the device plate 204, the lubrication chamber 212 is fixedly connected to the front of the device plate 204, the protrusion 213 is slidably connected to the inner wall of the lubrication chamber 212, the oil groove 215 is formed on the outer wall of the protrusion 213, one end of the spring 214 is fixedly connected to the top of the protrusion 213, and the other end of the spring 214 is fixedly connected to the top inner wall of the lubrication chamber 212. The oil inlet 216 is formed on the top of the lubrication chamber 212. The protrusion 213 contacts the spiral rod 203, the device plate 204 is movably connected to the outer circumferential surface of the spiral rod 203, the roller brush 210 contacts the spiral rod 203, and the fixing block 101 is fixedly connected to the top of the L-shaped rod 206. Working principle: When the device is placed at the bottom of the sun, the motor is started, driving the shaft 102 to rotate. The rotation of the shaft 102 drives the gear 103 to rotate, and at the same time, the gear 103 meshes with the rack 104, causing the photovoltaic panel 1 to move and unfold. At this time, the retaining strip 106 slides inside the positioning groove 107 under the translational movement of the photovoltaic panel 1. When the photovoltaic panel 1 is fully unfolded, the retaining strip 106 stops moving inside the positioning groove 107, providing support for the photovoltaic panel 1 and preventing the photovoltaic panel 1 from shaking during operation, thus avoiding damage to the device. After the photovoltaic panel 1 is unfolded, the contact area between the photovoltaic panel 1 and sunlight can be greatly increased, increasing the photovoltaic effect. The power generation efficiency of panel 1 is improved by reversing the drive motor when the device needs to be recycled. At this time, shaft 102 drives gear 103 to reverse, and the three photovoltaic panels 1 are stacked together, which facilitates the movement of photovoltaic panels 1 and saves the placement area required when photovoltaic panels 1 are idle. When photovoltaic panels 1 are unfolded or retracted, gear 103 meshes with transmission rack 104 to drive photovoltaic panels 1 to move horizontally. At this time, the outer surface of photovoltaic panels 1 will make full contact with brush strip 105 to remove impurities from the surface of photovoltaic panels 1, preventing excessive accumulation of impurities on the surface of photovoltaic panels 1 from affecting the working efficiency of photovoltaic panels 1, and also saving the cost of manual cleaning. When the photovoltaic panel 1 needs to find an angle that maximizes its contact area with sunlight, the motor at the rear of the drive screw 203 rotates the screw 203, causing the device plate 204 to move. The movement of the device plate 204 moves the slide block 207 at its top, which in turn moves the L-shaped rod 206. Simultaneously, the movement of the L-shaped rod 206 drives the crank rod 208 and the slider 209 in a circular motion, causing the slider 209 to slide on the outer wall of the L-shaped rod 206, thus causing the photovoltaic panel 1 to move in a circular motion and achieving the effect of adjusting the angle of the photovoltaic panel 1. Simultaneously, the movement of the device plate 204 also moves the lubrication chamber 212, which in turn moves the belt... As the movable protrusion 213 moves, when it slides into the spiral groove of the spiral rod 203, the spring 214 releases its elastic force, driving the protrusion 213 to move downward. At the same time, the oil groove 215 moves downward. At this time, the lubricating oil inside the lubrication chamber 212 drips down the oil groove 215 onto the surface of the spiral rod 203, providing lubrication for the spiral rod 203 and preventing rust from forming on the spiral rod 203 during long-term storage, which would affect the normal operation of the device. Meanwhile, as the device plate 204 moves, the roller brush 210 rolls back and forth on the surface of the spiral rod 203, cleaning the surface of the spiral rod 203 and evenly spreading the lubricating oil dripping from the lubrication chamber 212 for better lubrication.

[0015] Please see Figures 1-11 Based on the above embodiments, in another embodiment of the present invention, the protective shell 3 includes a protective plate 301, a reflective surface 302, a second bevel gear 303, and a rotating rod 304.

The protective shell 3 also includes a limiting circular groove 305, a limiting circle 306, a first support rod 307, a supporting spiral rod 308, and a third limiting circle. Angle 309, fixing strip 310, limiting groove 305 are fixedly connected to the outer wall of plate 205, limiting circle 306 is slidably connected to the inner wall of limiting groove 305, support rod 1 307 is fixedly connected to the outer circumference of limiting circle 306, support screw rod 308 is threadedly rotatably connected to the inner wall of support rod 1 307, limiting triangle 309 is fixedly connected to the top of support screw rod 308, fixing strip 310 is fixedly connected to the bottom outer wall of protective plate 301, bevel gear 2 303 meshes with bevel gear 1 108, limiting triangle 309 contacts fixing strip 310; Working principle: When the photovoltaic panel 1 unfolds, the shaft 102 rotates, driving the bevel gear 108 to rotate. At this time, the bevel gear 108 meshes with the transmission bevel gear 303, driving the protective plate 301 to rotate and unfold. At this time, the reflective surface 302 inside the protective plate 301 comes into contact with sunlight, and the protective plate 301 and the photovoltaic panel 1 are at a certain angle, reflecting the sunlight falling on the reflective surface 302 onto the surface of the photovoltaic panel 1, achieving the effect of concentrating light and improving the power generation efficiency of the photovoltaic panel 1. At this time, the support rod 307 is manually unfolded and the support screw rod 308 is rotated out, and the limiting triangular block 309 is locked at the bottom of the appropriate height fixing strip 310, which plays a supporting role for the protective shell 3. At the same time, the angle of the reflective surface 302 can be adjusted through multiple fixing strips 310. When the device is retracted, the shaft 102 drives the bevel gear 108 to reverse, meshing with the transmission bevel gear 303, which then drives the protective plate 301 to rotate, thereby covering the top of the photovoltaic panel 1, so that the photovoltaic panel 1 can be covered and protected by the protective plate 301 when it is not in use.
