Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic power generation equipment technology, and in particular to a high-efficiency integrated solar photovoltaic power generation device. Background Technology

[0002] Solar photovoltaic (PV) power generation modules, as core equipment for clean energy power generation, are widely used in many fields such as off-grid power supply, distributed power stations, photovoltaic agriculture, and municipal lighting. Photovoltaic energy collection and power generation is the most basic and most frequent process in the operation of PV power generation equipment. Therefore, maintaining the light energy collection efficiency of PV panels is the core condition for ensuring the overall power generation performance of PV power generation devices.

[0003] Currently, the photovoltaic (PV) power generation industry generally uses fixed PV panel installations combined with water spray for simple cleaning. However, after the PV panels are washed, fine water droplets easily remain on the surface. These residual water droplets, under strong sunlight, form micro-convex lenses that focus light and amplify ultraviolet intensity, easily causing localized hot spots, surface burns, and yellowing and aging of the surface film. After long-term operation, the power of the PV modules will be severely degraded, and power generation losses will continue to increase. Moreover, traditional PV cleaning only focuses on water rinsing. After rinsing, the water will air dry and mix with dust, forming a large number of water stains. This is not only incomplete and continuously reduces efficiency, but also repeatedly focuses sunlight and damages the panel surface. This is a long-standing hidden defect in the industry. Existing simple cleaning equipment relies on a single rotating brush for cleaning without a linked water suction and removal structure. This results in incomplete water removal and cannot fundamentally avoid the problem of water droplet-focused damage. Furthermore, it is not effective at cleaning stubborn stains, and the dust accumulation on the panels blocks sunlight, further reducing photoelectric conversion efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that water droplets and water stains are easily left on the surface of the panel after water washing. This not only concentrates and amplifies ultraviolet rays, causing the photovoltaic panel to age hot spots and reduce power, but also the scale and white spots left after the water dries will block the light and reduce the light transmittance. To this end, we propose a high-efficiency solar photovoltaic power generation integrated device.

[0005] To achieve the above objectives, this application employs the following high-efficiency solar photovoltaic power generation integrated device, including an embedded foundation, a circular shell installed on the top of the embedded foundation, a toothed ring plate fixedly connected to the top of the circular shell, a photovoltaic panel installed in the middle of the toothed ring plate, a shaft shell fixedly connected to the middle of the inner wall of the circular shell, a base rotatably connected to the top of the shaft shell, a brush cylinder installed on one side of the base, and an absorbent sponge provided at the bottom of the brush cylinder; The circular shell is equipped with a mechanism to prevent damage from concentrated light. The mechanism includes a first motor fixed to the bottom of the circular shell and a sleeve that meshes with the first motor. The surface of the sleeve has two arc grooves. The motor drives the base to rotate and lift through the arc groove trajectory, thereby lifting the water-absorbing sponge to fit the photovoltaic panel surface and complete the wiping and water removal. The self-drainage mechanism is connected to the anti-focusing damage mechanism. The self-drainage mechanism includes a rotating shell rotatably connected to the surface of the shaft housing and a mesh push plate. The rotating shell rotates synchronously with the base, driving the mesh push plate to periodically lift and squeeze the absorbent sponge, automatically discharging the water absorbed inside the absorbent sponge, and continuously ensuring the cleaning performance of the absorbent sponge. The cleaning effect enhancement mechanism is connected to the anti-focusing damage mechanism. Relying on the meshing transmission of the toothed ring plate, it drives the brush cylinder to rotate and clean while completing axial reciprocating movement.

[0006] Preferably, the integrated high-efficiency solar photovoltaic power generation device further includes: A self-adjusting mechanism for tracking light, wherein the self-adjusting mechanism for tracking light is disposed between the embedded foundation and the circular shell; The wind-resistant self-retracting mechanism is located inside the embedded foundation.

[0008] Preferably, the self-draining mechanism includes: One end of the L-shaped plate is slidably connected to one side of the rotating shell. A raised ring plate is fixedly connected to the bottom of the inner wall of the circular shell. The rotating shell is rotatably connected to the surface of the raised ring plate. A collection shell is fixedly connected to the top of the rotating shell. A lifting slide plate is slidably connected inside the rotating shell. A second spring is fixedly connected to all four sides of the lifting slide plate. The bottom of the second spring is fixedly connected to the bottom of the inner wall of the rotating shell. The mesh push plate is fixedly connected to the top of the lifting slide plate by a slide rod and passes through the collection shell.

[0009] Preferably, the cleaning effect enhancement mechanism includes: A sleeve rod is fixedly connected to the inside of the brush cylinder. Two protrusions are fixedly connected to both ends of the sleeve rod. A central shaft is slidably connected to the inner wall of the sleeve rod. A third gear is fixedly connected to one side of the central shaft. The surface of the third gear meshes with the top of the gear ring plate. A guide cylinder is fixedly connected to one side of the base and one side of the water spray device. The protrusions are slidably connected to the inner wall of the guide cylinder.

[0010] Preferably, the self-adjusting light-tracking mechanism includes: A disc has support plates fixedly connected to both sides of its top. The top of the support plates is rotatably connected to the bottom of the disc. A hydraulic rod is rotatably connected to the top of the disc, and the other end of the hydraulic rod is rotatably connected to the bottom of the disc. A support column is rotatably connected to the middle of the disc. A transmission gear is fixedly connected to the top of the support column. A servo motor is fixedly connected to the bottom of the disc. An output gear is fixedly connected to the output end of the servo motor, and one side of the output gear meshes with the surface of the transmission gear.

[0011] Preferably, the wind-resistant self-closing mechanism includes: A limiting sleeve is fixedly connected to the middle of the embedded foundation. A second motor is fixedly connected to the top of the inner wall of the embedded foundation. A drive gear is installed on the top of the inner wall of the embedded foundation. The output end of the second motor is fixedly connected to the drive gear. The surface of the drive gear meshes with the tooth groove on the side of the support column.

[0012] Preferably, a blade power generation device is installed on the surface of the circular shell, and an energy storage battery is installed inside the embedded foundation.

[0013] Preferably, one side of the limiting block is a plane, and the front end of the limiting block is an arc surface structure.

[0014] The technical effects and advantages of this invention are as follows: In this invention, by setting up a linkage trajectory sequence action for the anti-concentration damage mechanism, the operation logic of first washing and cleaning the photovoltaic panel with water, and then raising the water-absorbing sponge to completely wipe away residual water is realized. Relying on the lifting and rotation sequence of the circular groove and the lifting groove trajectory groove limit control component, water droplets and residual water film on the photovoltaic panel surface are thoroughly removed, eliminating the problems of water droplets concentrating and forming hot spots, panel burns, and film aging and degradation under strong light. At the same time, it avoids the accumulation of scale and white spots after the water dries and blocks light, effectively stabilizing the light transmittance and photoelectric conversion efficiency of the photovoltaic panel, significantly reducing the long-term power decay rate of the module, and extending the overall service life of the equipment.

[0015] In this invention, the rotation stroke of the anti-concentration damage mechanism is linked to the synchronous operation of the self-draining mechanism, realizing automatic water squeezing and drainage without additional power. During the base rotation, the raised ring plate pushes the lifting slide plate and the mesh push plate to move up and down repeatedly, continuously squeezing and dehydrating the water-absorbing sponge, and removing the water adsorbed inside the water-absorbing sponge in real time. This avoids the decline in cleaning and water removal performance after the water-absorbing sponge becomes saturated with water. No manual disassembly, cleaning and maintenance are required, ensuring that the water removal effect of each photovoltaic panel wipe is uniform and stable. It realizes the integrated sequential automatic operation of cleaning, water absorption and drainage, and is suitable for unattended continuous operation and maintenance scenarios in the field.

[0016] In this invention, the cleaning effect enhancement mechanism is linked with the cleaning action. The toothed ring plate meshing transmission causes the brush cylinder to rotate while moving axially back and forth. This changes the limitations of traditional single circumferential cleaning. It can deeply scrape and loosen the solidified dust, stubborn stains and particulate impurities on the surface of photovoltaic panels, effectively solving the problems of dirt accumulation on the surface of photovoltaic panels blocking light and incomplete cleaning. It can continuously maintain the high light transmittance of the photovoltaic panel surface, steadily improve the photovoltaic power generation efficiency, and reduce the frequency of operation and maintenance cleaning and labor costs.

[0017] In this invention, a self-adjusting mechanism for tracking sunlight is set up to achieve automatic adjustment of the azimuth and pitch angles of the photovoltaic panel in two dimensions. It can dynamically calibrate the orientation of the entire circular shell panel in real time by following the trajectory of sunlight. The pitch angle is adjusted by the extension and retraction of the hydraulic rod, and the horizontal orientation is adjusted by the meshing and rotation of the output gear and the transmission gear. This ensures that the working surface of the photovoltaic panel always maintains the optimal angle of sunlight reception, maximizing the reception of solar radiation. This overcomes the shortcomings of traditional fixed brackets, such as low light energy utilization and high power generation loss, and significantly improves the overall power generation capacity and environmental adaptability of the device.

[0018] In this invention, under severe wind conditions, the second motor and drive gear transmission can drive the support column to slide along the limiting sleeve, causing the entire shell to automatically descend and be stored, reducing the windward area of ​​the photovoltaic panel, effectively weakening the impact load of strong winds, and preventing the photovoltaic panel from bending, structural shaking, deformation and damage. This achieves automatic protection against severe weather, and automatically resets and resumes power generation after the wind stabilizes. At the same time, the whole machine adopts single-power linkage timing control of the first motor, with multiple processes linked synchronously, eliminating the need for multiple sets of sensors to trigger step by step. The control logic is simple, the failure rate is low, and the degree of automation integration is high, which greatly reduces the equipment manufacturing cost and operation and maintenance difficulty.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0022] Reference Figure 1 - Figure 12 As shown, the present invention provides an integrated high-efficiency solar photovoltaic power generation device, including an embedded foundation 1, a circular shell 2 installed on the top of the embedded foundation 1, a toothed ring plate 3 fixedly connected to the top of the circular shell 2, a photovoltaic panel 4 installed in the middle of the toothed ring plate 3, a shaft shell 5 fixedly connected to the middle of the inner wall of the circular shell 2, a base 6 rotatably connected to the top of the shaft shell 5, a brush cylinder 7 installed on one side of the base 6, and an absorbent sponge 8 provided at the bottom of the brush cylinder 7.

[0023] Furthermore, refer to Figure 1 - Figure 9 As shown, the inside of the circular shell 2 is provided with a mechanism to prevent light-focusing damage. The mechanism includes a first motor 9 fixed to the bottom of the circular shell 2 and a sleeve 13 that meshes and drives with the first motor 9. Two arc grooves 14 are opened on the surface of the sleeve 13. The output end of the first motor 9 is fixedly connected to the first gear 10. The bottom of the base 6 is fixedly connected to the column 11. Both sides of the bottom of the column 11 are fixedly connected to the protruding rods 12. The sleeve 13 is slidably connected to the surface of the column 11. The protruding rods 12 are slidably connected to the inner wall of the arc groove 14. The bottom of the sleeve 13 is fixedly connected to the second gear 15. One side of the second gear 15 is meshed with the first gear 10. A water spraying device 16 is fixedly connected to one side of the base 6. The brush cylinder 7 is installed on the water spraying device 16. At the bottom of base 6, an L-shaped plate 17 is fixedly connected to one side of the base 6. A limiting block 18 is slidably connected in a groove on one side of the L-shaped plate 17. Two first springs 19 are fixedly connected to one side of the limiting block 18. The other end of the first spring 19 is fixedly connected to the inner wall of the L-shaped plate 17. Two circular grooves 20 are opened on the inner wall of the circular shell 2. The two circular grooves 20 are distributed vertically. A lifting groove 21 is opened between the two circular grooves 20 for communication. A triangular stop block 22 is fixedly connected to one side of the inner wall of each of the two circular grooves 20.

[0024] The photovoltaic panel 4 directly faces the sun to capture light energy and convert it into electrical energy, which is stored in the energy storage battery inside the embedded foundation 1. After long-term use, dust and foreign objects will be absorbed on the surface of the photovoltaic panel 4. The first motor 9 will run to drive the first gear 10 to rotate, which will drive the second gear 15 to make the casing 13 rotate synchronously. like Figure 4 As shown, when the second gear 15 and the housing 13 rotate counterclockwise, the protruding rod 12 is at the bottom of the inner wall of the arc groove 14. At this time, the rotation of the housing 13 will drive the column 11, the base 6, the L-shaped plate 17 and the limiting block 18 to rotate synchronously. This makes the limiting block 18 slide counterclockwise along the circular groove 20 from the bottom of the initial position lifting groove 21, so that the brush cylinder 7 rotates counterclockwise on the surface of the photovoltaic panel 4 to brush. The water spraying device 16 first runs and sprays water from both sides onto the surface of the photovoltaic panel 4 to rinse and remove floating dust. Then the brush cylinder 7 adheres to the surface of the water-absorbing sponge 8 and rotates to brush stubborn dirt. At the same time, the water spraying device 16 continuously rinses the surface of the photovoltaic panel 4 to remove dirt. When the second gear 15 and the sleeve 13 are rotated counterclockwise to... Figure 9 When the limit block 18 is on the right side of the bottom circular groove 20, it will contact the right triangular stop 22. The inclined surface of the triangular stop 22 guides the limit block 18 to move inward into the L-shaped plate 17 and compresses the first spring 19 to store energy. When the limit block 18 rotates about past the triangular stop 22, the first spring 19 will rebound and push the limit block 18 back to the bottom area of ​​the lifting groove 21. After the base 6 and the brush cylinder 7 rotate multiple times to clean the surface of the photovoltaic panel 4, the dust on the surface of the photovoltaic panel 4 is completely removed. However, at this time, the surface of the photovoltaic panel 4 will have moisture due to water washing. When the limiting block 18 and the base 6 rotate to the initial angle position, the first motor 9 will run in the opposite direction to drive the second gear 15 and the sleeve 13 to rotate clockwise. At this time, the protruding rod 12 is at the bottom of the inner wall of the arc groove 14, while the limiting block 18 is at the bottom of the inner wall of the circular groove 20. The position of the limiting block 18 is restricted by the right triangular stop block 22, so that the L-shaped plate 17 and the limiting block 18 cannot rotate clockwise. This causes the sleeve 13 to first drive the protruding rod 12 to passively spiral up along the bottom of the inner wall of the arc groove 14 to the top of the inner wall of the arc groove 14 when it rotates clockwise, so as to raise the height of the base 6 and the L-shaped plate 17, and the limiting block 18 rises synchronously with the L-shaped plate 17. This causes the limiting block 18 to rise along the lifting groove 21 until it is flush with the top of the circular groove 20. Then, the right side of the limiting block 18 is unrestricted. At this point, the column 11, the protruding rod 12, the base 6, and the L-shaped plate 17 have completed their rising motion. The right side of the limiting block 18 is unrestricted, and the protruding rod 12 slides to the top of the inner wall of the arc groove 14. Subsequently, the sleeve 13 continues to rotate clockwise, restricting the height of the protruding rod 12 and the column 11, causing the column 11 and the base 6 to rotate clockwise along with the sleeve 13. This also causes the limiting block 18 to rotate clockwise along the circular groove 20 in the top area. At this time, the L-shaped plate... 17 completes the upward movement, and the water-absorbing sponge 8 is on top of the photovoltaic panel 4. When the L-shaped plate 17 and the water-absorbing sponge 8 rotate clockwise, the water-absorbing sponge 8 slides along the surface of the photovoltaic panel 4. The water-absorbing sponge 8 is a high-performance sponge. The water-absorbing sponge 8 will absorb the moisture on the surface of the photovoltaic panel 4 to remove the water droplets on the surface of the photovoltaic panel 4 after being washed by the water flow. The removal of this moisture by the water-absorbing sponge 8 is used to avoid the formation of countless micro-convex lenses on the surface of the photovoltaic panel 4 due to water droplets adhering to the surface, which would focus sunlight and cause a sudden increase in local temperature of the photovoltaic panel 4, forming a hot spot effect and causing damage to some areas of the photovoltaic panel 4. When the limiting block 18 rotates clockwise once and contacts the triangular stop 22 on the left side of the top circular groove 20, the limiting block 18 will retract and push the first spring 19 to store force. After the limiting block 18 passes the triangular stop 22, the first spring 19 rebounds and pushes the limiting block 18 back to the top area of ​​the lifting groove 21. At this time, the sleeve 13 will rotate counterclockwise by the first motor 9. At this time, the left side of the limiting block 18 is restricted by the triangular stop 22 on the top side of the lifting groove 21. At this time, the limiting block 18 cannot rotate counterclockwise to pass the top triangular stop 22. This causes the protruding rod 12 to slide down the arc groove 14 to the bottom, which reduces the height of the base 6 and the L-shaped plate 17 and resets the initial position. Then the base 6 and the L-shaped plate 17 can rotate clockwise by the operation of the first motor 9 to drain the water-absorbing sponge 8 using the self-draining mechanism. The water-absorbing sponge 8 rises, absorbs water and wipes once, then moves down to its original position to drain the water, and rises again to absorb water and wipe. This process removes moisture from the surface of the photovoltaic panel 4. After repeated wiping, the moisture on the surface of the photovoltaic panel 4 is completely removed, preventing damage to the photovoltaic panel 4 due to water droplets. The surface of the photovoltaic panel 4 is also cleaned, ensuring that dirt and foreign objects do not affect its light reception efficiency.

[0025] Furthermore, refer to Figure 5 and Figure 6 As shown, the high-efficiency solar photovoltaic power generation integrated device also includes a self-draining mechanism, which is connected to the anti-concentration damage mechanism. The self-draining mechanism includes a rotating shell 23 rotatably connected to the surface of the shaft housing 5, and a mesh push plate 28. One end of the L-shaped plate 17 is slidably connected to one side of the rotating shell 23. A raised ring plate 24 is fixedly connected to the bottom of the inner wall of the round shell 2. The rotating shell 23 is rotatably connected to the surface of the raised ring plate 24. A collection shell 25 is fixedly connected to the top of the rotating shell 23. A lifting slide plate 26 is slidably connected inside the rotating shell 23. A second spring 27 is fixedly connected to all four sides of the lifting slide plate 26. The bottom of the second spring 27 is fixedly connected to the bottom of the inner wall of the rotating shell 23. A mesh push plate 28 is fixedly connected to the top of the lifting slide plate 26 through a slide rod and passes through the collection shell 25.

[0026] When the base 6 rotates counterclockwise in the unraised state, the L-shaped plate 17 is embedded in one side of the rotating shell 23, causing the rotating shell 23 to rotate synchronously along the surface of the shaft shell 5. This causes the rotating shell 23 to rotate counterclockwise along the surface of the raised ring plate 24, while the lifting slide plate 26 slides along the surface of the raised ring plate 24. When the rotating shell 23 and the lifting slide plate 26 rotate to the protrusion of the raised ring plate 24, the inclined surface of the protrusion of the raised ring plate 24 will guide the lifting slide plate 26 to move upward, thereby raising the height of the lifting slide plate 26 and pulling the second spring 27 to store force. After the lifting slide plate 26 rotates past the protrusion of the raised ring plate 24, the second spring 27 will pull the lifting slide plate 26 back to the bottom. When the lifting slide plate 26 moves upward, it will push the mesh push plate 28 upward. Since the rotating shell 23 rotates synchronously with the L-shaped plate 17, the mesh push plate 28 is always at the bottom of the water-absorbing sponge 8. When the water-absorbing sponge 8 is not in the rising state, the rising of the mesh push plate 28 will squeeze the water-absorbing sponge 8 to squeeze out the water inside the water-absorbing sponge 8. The water will flow downward into the interior of the collection shell 25 to keep the water-absorbing sponge 8 dry after use. Thus, the drying treatment of the water-absorbing sponge 8 and the water absorption treatment of the photovoltaic panel 4 can be switched by the forward and reverse rotation mode of the first motor 9.

[0027] Furthermore, refer to Figure 5 and Figure 7As shown, the high-efficiency solar photovoltaic power generation integrated device also includes a cleaning effect enhancement mechanism, which is connected to the anti-concentration damage mechanism. Cleaning effectiveness enhancement mechanisms include: The sleeve rod 29 is fixedly connected to the inside of the brush cylinder 7. Two protrusions 30 are fixedly connected to both ends of the sleeve rod 29. A central shaft rod 31 is slidably connected to the inner wall of the sleeve rod 29. A third gear 32 is fixedly connected to one side of the central shaft rod 31. The surface of the third gear 32 meshes with the top of the gear ring plate 3. A guide cylinder 33 is fixedly connected to one side of the base 6 and one side of the water spray device 16. The protrusions 30 are slidably connected to the inner wall of the guide cylinder 33.

[0028] When the base 6 and the water spray device 16 rotate counterclockwise to clean the surface of the photovoltaic panel 4, the counterclockwise rotation of the water spray device 16 causes the third gear 32 to rotate counterclockwise along the surface of the gear ring plate 3. The third gear 32 is driven to rotate by meshing with the surface of the gear ring plate 3. The rotation of the third gear 32 and the central shaft 31 drives the sleeve rod 29 to rotate synchronously. Although the sleeve rod 29 rotates with the central shaft 31, it can also slide back and forth a short distance along the surface of the central shaft 31. This causes the protrusion 30 to slide along the inner wall of the guide cylinder 33 when the sleeve rod 29 rotates. The inner wall of the guide cylinder 33 has a concave-convex annular structure. When the sleeve rod 29 rotates, the guide cylinder 33 guides the protrusion 30, so that the sleeve rod 29 rotates with the central shaft rod 31 and moves continuously and repeatedly along the surface of the central shaft rod 31 for a certain distance. This drives the brush cylinder 7 to rotate and reciprocate axially, shaking off and loosening the particulate impurities adsorbed on the surface of the brush cylinder 7 during the brushing process. At the same time, the repeated movement can also improve the scraping and cleaning effect on the surface of the photovoltaic panel 4, further ensuring the cleanliness of the surface of the photovoltaic panel 4 and maintaining the light energy conversion efficiency of the photovoltaic power generation panel. Furthermore, a dustproof shell is fixedly connected to the outside of the water spraying device 16. The dustproof shell is placed outside the third gear 32, and its structure matches the size of the gear ring plate 3. When the water spraying device 16 is at the initial height, the dustproof shell merges with the surface of the gear ring plate 3 to protect the top of the gear ring plate 3 from dust. When the water spraying device 16 rises, the dustproof shell separates from the top of the gear ring plate 3.

[0029] Further preferred options are those that refer to... Figure 10 and Figure 11 As shown, the high-efficiency solar photovoltaic power generation integrated device also includes a light-tracking self-adjusting mechanism, which is located between the embedded foundation 1 and the circular shell 2.

[0030] The self-adjusting mechanism for tracking light includes: The disc 34 has support plates 35 fixedly connected to both sides of its top. The top of the support plates 35 is rotatably connected to the bottom of the circular shell 2. The top of the disc 34 is rotatably connected to a hydraulic rod 36, and the other end of the hydraulic rod 36 is rotatably connected to the bottom of the circular shell 2. The middle of the disc 34 is rotatably connected to a support column 37. The top of the support column 37 is fixedly connected to a transmission gear 38. The bottom of the disc 34 is fixedly connected to a servo motor 39. The output end of the servo motor 39 is fixedly connected to an output gear 40, and one side of the output gear 40 meshes with the surface of the transmission gear 38.

[0031] A disc 34 has support plates 35 fixedly connected to both sides of its top. The top of the support plates 35 is rotatably connected to the bottom of the circular shell 2. A hydraulic rod 36 is rotatably connected to the top of the disc 34, and the other end of the hydraulic rod 36 is rotatably connected to the bottom of the circular shell 2. A support column 37 is rotatably connected to the middle of the disc 34. A transmission gear 38 is fixedly connected to the top of the support column 37. A servo motor 39 is fixedly connected to the bottom of the disc 34. An output gear 40 is fixedly connected to the output end of the servo motor 39. One side of the output gear 40 is connected to the transmission gear 38. The photovoltaic panel 4 is connected by a surface meshing connection. A light-tracking sensor installed at the top center of the base 6 collects the light difference values ​​in various directions. Then, the orientation and angle of the photovoltaic panel 4 are changed according to the data. The operation of the hydraulic rod 36 pushes the circular shell 2 to rotate along the top of the support plate 35, changing the tilt angle of the circular shell 2. Then, the servo motor 39 starts and drives the output gear 40 to rotate. The disc 34 is rotatably connected to the top of the support column 37. When the output gear 40 rotates, it meshes with the surface of the transmission gear 38. The output gear 40 causes the disc 34 to rotate, thereby changing the orientation angle of the circular shell 2. This enables real-time self-adjustment of the angle of the photovoltaic panel 4, ensuring that the working surface of the photovoltaic panel 4 always faces the sun, improving the overall light reception efficiency, reducing power generation loss caused by light angle deviation, solving the problem that the photovoltaic device cannot automatically adjust the angle with changes in light and has low power generation efficiency, and thus improving the overall power generation performance of the integrated photovoltaic power generation device.

[0032] The improved wind-resistant self-retracting mechanism is installed inside the embedded foundation 1. Under severe wind conditions, the second motor 42 drives the entire circular shell 2 to automatically descend and retract, reducing the wind-facing area of ​​the photovoltaic panel 4, achieving automatic wind protection, and avoiding panel deformation and structural damage caused by strong wind impact. Further preferred options are those that refer to... Figure 10 - Figure 12 As shown, the high-efficiency solar photovoltaic power generation integrated device also includes a wind-resistant self-retracting mechanism, which is located inside the embedded foundation 1.

[0033] Wind-resistant self-closing mechanisms include: A limiting sleeve 41 is fixedly connected to the middle of the embedded base 1. A second motor 42 is fixedly connected to the top of the inner wall of the embedded base 1, and a drive gear 43 is installed on the top of the inner wall of the embedded base 1. The output end of the second motor 42 is fixedly connected to the drive gear 43, and the surface of the drive gear 43 meshes with the tooth groove on the side of the support column 37. When the wind is strong, in order to avoid damage to the device, the second motor 42 will drive the drive gear 43 to rotate counterclockwise, causing the drive gear 43 to rotate and drive the support column 37 to slide downward along the limiting sleeve 41, thereby reducing the height of the device. This allows the photovoltaic panel 4 to descend into the circular area at the top of the embedded base 1 for storage. It should be noted that the angle of the circular shell 2 is [missing information]. Figure 1 Medium state; The embedded foundation 1 is installed deep underground. The reduced height of the circular shell 2 and toothed ring plate 3 decreases the contact area with strong winds, effectively reducing the impact of strong winds on the device structure, preventing damage to the photovoltaic panels, improving the structural stability and service life of the device in severe wind conditions, and completing the self-protection and storage of the device under severe typhoon weather. After the wind force drops to a safe range, the second motor 42 runs in reverse, driving the drive gear 43 to rotate clockwise, which in turn drives the support column 37 to slide upward along the limit sleeve 41, pushing the photovoltaic panel 4 back to the working height to resume power generation. The entire storage and reset process can be automatically triggered by the wind force sensing module without manual operation, making it suitable for unattended photovoltaic power generation scenarios in the field.

[0034] Furthermore, refer to Figure 2 and Figure 12 As shown, a paddle generator 44 is installed on the surface of the circular shell 2, and an energy storage battery is installed inside the embedded base 1. The electricity generated by photovoltaic power generation is transmitted to the energy storage battery for storage. At the same time, the energy storage battery can provide operating power for the device's electric drive components, eliminating the need for additional external power supply lines and further reducing the deployment cost of the device in the field. The paddle generator 44 is a wind power generation device. When the device is raised to the working state, the paddle generator 44 is driven by the wind to rotate and generate electricity, which can also be transmitted to the energy storage battery for storage. It can combine photovoltaic power generation and wind power generation modes, and can still generate electricity continuously during periods of insufficient sunlight but sufficient wind, improving the overall power generation efficiency and environmental adaptability of the device. It effectively solves the problem of power generation interruption of single photovoltaic power generation in low-light scenarios such as rain, night, etc., allowing the device to continuously output electricity and further improving the practical performance of this integrated device in complex field environments.

[0035] Furthermore, refer to Figure 7 and Figure 8As shown, one side of the limiting block 18 is a plane, and the front end of the limiting block 18 is an arc surface structure. Because one side of the limiting block 18 is an arc surface and the other side is a plane, when the limiting block 18 rotates in a direction that causes its own plane to contact the plane of one side of the triangular stop 22, the limiting block 18 will not be able to continue rotating to that side. When the limiting block 18 rotates and contacts the inclined surface of the triangular stop 22, the limiting block 18 will retract due to the guidance of the inclined surface of the triangular stop 22 and continue to rotate and move.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
