Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage and charging technology, and in particular to an adjustable-angle integrated photovoltaic energy storage and charging pile and its solar panel tracking system. Background Technology

[0002] Photovoltaic-storage-charging integration refers to the integration of photovoltaic power generation technology and equipment, energy storage technology and equipment, and charging technology and equipment into a single device for comprehensive energy utilization. Chinese invention patent application number 202421046793.6 provides a new energy charging pile integrating photovoltaic, energy storage, and charging. This patent describes a system where "after the servo motor starts, it drives multiple photovoltaic panels to move towards the bottom center of a cover plate. The photovoltaic panels are then blocked by the cover plate, preventing damage from severe weather such as snow and hail, thus extending their lifespan." However, it has several shortcomings: First, the photovoltaic panels lack angle adjustment capabilities, maintaining only a single angle and failing to adapt to varying latitudinal light angles, thus hindering efficient power generation. Second, the photovoltaic panels lack automatic light tracking capabilities, making it difficult to flexibly adapt to different light angles and further limiting efficient power generation. Third, it lacks a cleaning mechanism for the photovoltaic panels, which easily accumulate dust after long-term use, reducing power generation efficiency. These shortcomings highlight the deficiencies of the existing technology. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable-angle integrated photovoltaic, energy storage, and charging pile and its solar panel tracking system to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-angle integrated solar-energy storage and charging pile includes an integrated charging pile with a vertical support cylinder and a first servo motor fixed at the top. The first servo motor has a braking function and is located inside the support cylinder. The support cylinder is rotatably connected to a rotating seat, which is coaxially fixed to the rotating shaft of the first servo motor. A second servo motor with a braking function is fixed at the front end of the rotating seat. The rotating shaft of the second servo motor is rotatably connected to the rotating seat and a worm gear is coaxially fixed to its rotating shaft. A support shaft is rotatably connected to the upper part of the rotating seat in a horizontal direction. A worm wheel is coaxially fixed to the support shaft, and a support seat is radially fixed thereto. The worm wheel meshes with the worm gear. A telescopic mechanism and a protective plate are installed at the top of the support seat. The telescopic mechanism is equipped with multiple solar panels and is used to control the horizontal convergence and diffusion of the solar panels. The protective plate is located at the top of the solar panels and is used to shield the converged solar panels. The first servo motor, the second servo motor, and the solar panels are electrically connected to the electronic control system of the integrated solar-energy storage and charging pile.

[0005] Based on the above technical solution, the telescopic mechanism includes a guide seat, a lead screw, a driven bevel gear, a No. 3 servo motor, a driving bevel gear, and a slider. Multiple horizontal guide seats are fixed at the top circumference of the support seat in a centripetal configuration. Each guide seat is rotatably connected to a lead screw, which is arranged at a centripetal angle to the same virtual center. Driven bevel gears are coaxially fixed at adjacent ends. A vertical No. 3 servo motor is fixed to the support seat, and a driving bevel gear is coaxially fixed to the shaft of the No. 3 servo motor. Each guide seat is slidably connected to a slider along the axial direction of its corresponding lead screw. Each slider is threadedly connected to the lead screw. A horizontal solar panel is fixed to the top of each slider. The No. 3 servo motor is electrically connected to the electronic control system of the integrated charging pile.

[0006] Based on the above technical solution, the No. 3 servo motor is fixed with a support member, which is fixed to the protective plate. The protective plate is parallel to the solar panel, and multiple elongated cleaning brushes are fixed at the bottom of the protective plate. Each cleaning brush is eccentrically positioned at an equal angle relative to the rotating shaft of the No. 3 servo motor. The bristles of the cleaning brushes are in contact with the upper surface of the solar panel. When the No. 3 servo motor rotates forward and backward, the active bevel gear and the driven bevel gear enable each lead screw to rotate forward and backward. During forward and backward rotation, the support member and the protective plate enable each cleaning brush to move forward and backward in the circumferential direction. When each lead screw rotates forward and backward, the slider enables each solar panel to move closer to each other and further away from each other. When the solar panels move closer to each other, the tangential direction of the circumferential movement of each cleaning brush is further away from the rotating shaft of the No. 3 servo motor than when the solar panels move further away from each other.

[0007] Based on the above technical solution, the support base and the top of the integrated charging pile are both fixed with bamboo tubes, and the bamboo tubes are intermittently inserted into the support cylinder, the second servo motor, the worm gear and the worm wheel.

[0008] Based on the above technical solution, a solar panel tracking system is provided for an adjustable-angle integrated solar-energy storage and charging pile. The support component is a support frame with open top and bottom. A vertical protective cover is fixed at the top of the support base. The top of the protective cover is dome-shaped and the bottom is cylindrical. The top of the protective cover is transparent and the bottom is opaque. Two sets of photosensitive sensors are fixed at a horizontal cross angle at the bottom of the protective cover. Each set of photosensitive sensors contains two photosensitive sensors arranged horizontally and correspondingly. Each photosensitive sensor is located at the left, rear, right, and front of the protective cover, respectively. Each photosensitive sensor is electrically connected to the electronic control system of the integrated solar-energy storage and charging pile.

[0009] Based on the above technical solution, the support frame is made of transparent material, a vertical drive shaft is fixed in the middle of the support frame, the drive shaft is coaxially fixed with the shaft of the No. 3 servo motor, an arc-shaped brush is fixed on the upper part of the support frame, the bristles of the arc-shaped brush are in contact with the top of the upper part of the protective cover, and a horizontal partition is fixed at the bottom of the protective cover. The partition is interlocked with the drive shaft and can rotate relative to the drive shaft.

[0010] Compared with the prior art, the present invention has the following advantages: by controlling the first servo motor to rotate forward and backward, the support base can be rotated horizontally; by controlling the second servo motor to rotate forward and backward, the support base can be swung back and forth, thereby enabling the solar panel to better adapt to the sunlight angle of different latitude regions and improve power generation efficiency. When the solar panel retracts, the circumferentially moving cleaning brush can sweep away the dust on the surface of the solar panel and drive the loose dust outward, thereby achieving the effect of cleaning and dust removal of the solar panel. After cleaning, when the solar panel re-extends, the power generation efficiency can be improved. At the same time, the curved brush can be used to clean the protective cover, thereby ensuring the cleanliness of the protective cover so that the photosensitive sensor can receive light, thus ensuring the tracking function. The partition can reduce the entry of dust. Two sets of cross-shaped photosensitive sensors can sense light. When the protective cover is not pointing towards the sun, sunlight shines through the top of the cover onto some of the photosensitive sensors. This creates a difference in sensing data between the photosensitive sensors and those that are not illuminated. The electronic control system senses this difference and drives the first and second servo motors to rotate accordingly, thereby adjusting the left-right and front-back angles of the protective cover to achieve tracking and reach the optimal angle for receiving sunlight, thus improving power generation efficiency.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-4 As shown, an adjustable-angle integrated photovoltaic energy storage and charging pile includes an integrated energy storage and charging pile 1. A vertical support cylinder 2 and a first servo motor 3 are fixed to the top of the integrated energy storage and charging pile 1. The first servo motor 3 has a braking function and is located inside the support cylinder 2. A rotating seat 4 is rotatably connected to the support cylinder 2. The rotating seat 4 is coaxially fixed to the rotating shaft of the first servo motor 3. A second servo motor 6 with a braking function is fixed to the front end of the rotating seat 4. The rotating shaft of the second servo motor 6 is rotatably connected to the rotating seat 4 through it, and a worm gear 7 is coaxially fixed to its rotating shaft. The upper part of the rotating seat 4 is horizontally aligned with the left and right sides. A support shaft 8 is rotatably connected in the horizontal direction. A worm gear 9 is coaxially fixed to the support shaft 8, and a support seat 10 is radially fixed to it. The worm gear 9 meshes with the worm 7. A telescopic mechanism and a protective plate 12 are installed at the top of the support seat 10. Multiple solar panels 13 are installed on the telescopic mechanism. The telescopic mechanism is used to control the horizontal convergence and diffusion of each solar panel 13. The protective plate 12 is located at the top of the solar panels 13 and is used to shield the converged solar panels 13. The first servo motor 3, the second servo motor 6, and the solar panels 13 are electrically connected to the electrical control system of the integrated energy storage and charging pile 1.

[0018] In use, the solar panel 13 receives sunlight and generates electrical energy, which is stored in the integrated charging pile 1 for powering electrical appliances. By controlling the telescopic mechanism, the solar panels 13 can be brought together and spread out. When the solar panels 13 are spread out, they can extend from under the protective plate 12 to receive sunlight and generate electricity. When they are retracted, the protective plate 12 can protect the solar panels 13. By controlling the first servo motor 3 to rotate forward and backward, the support base 10 can be rotated horizontally. By controlling the second servo motor 6 to rotate forward and backward, the support base 10 can be swung back and forth, so that the solar panel 13 can better adapt to the sunlight angle of different latitude regions and improve the power generation efficiency.

[0019] The telescopic mechanism includes a guide seat 14, a lead screw 15, a driven bevel gear 16, a third servo motor 17, a driving bevel gear 18, and a slider 19. Multiple horizontal guide seats 14 are fixed at the top of the support base 10 in a centripetal shape with equal circumference. Each guide seat 14 is rotatably connected to a lead screw 15, which is arranged in a centripetal shape with equal circumference around a virtual center. Driven bevel gears 16 are coaxially fixed at adjacent ends. A vertical third servo motor 17 is fixed to the support base 10. The driving bevel gear 18 is coaxially fixed to the shaft of the third servo motor 17. Each guide seat 14 is slidably connected to a slider 19 along the axial direction of its corresponding lead screw 15. Each slider 19 is threadedly connected to the lead screw 15. A horizontal solar panel 13 is fixed to the top of each slider 19. The third servo motor 17 is electrically connected to the electrical control system of the integrated charging pile 1.

[0020] The third servo motor 17 is fixed with a support member, which is fixed to the protective plate 12. The protective plate 12 is parallel to the solar panel 13. Multiple elongated cleaning brushes 21 are fixed at the bottom of the protective plate 12. Each cleaning brush 21 is eccentrically positioned at an equal angle relative to the axis of rotation of the third servo motor 17. The bristles of the cleaning brushes 21 are in contact with the upper surface of the solar panel 13. When the third servo motor 17 rotates forward and backward, the active bevel gear 18 and the driven bevel gear 16 enable each lead screw 15 to rotate forward and backward. During forward and backward rotation, the support member and the protective plate 12 enable each cleaning brush 21 to move forward and backward in the circumferential direction. When each lead screw 15 rotates forward and backward, the slider 19 enables each solar panel 13 to move closer to each other and further away from each other. When each solar panel 13 moves closer to each other, the tangential direction of the circumferential movement of each cleaning brush 21 is further away from the axis of rotation of the third servo motor 17 than the tangential direction of the circumferential movement of each cleaning brush 21 when each solar panel 13 moves further away from each other.

[0021] Furthermore, by controlling the No. 3 servo motor 17 to rotate forward and backward, the solar panel 13 can be extended and retracted. When the solar panel 13 retracts, the circumferentially moving cleaning brush 21 can sweep away the dust on the surface of the solar panel 13 and drive the detached dust outward, thereby achieving the effect of cleaning and dust removal of the solar panel 13. After cleaning is completed, when the solar panel 13 extends again, the power generation efficiency can be improved.

[0022] The support base 10 and the top of the integrated charging pile 1 are both fixed with a bamboo tube 22. The bamboo tube 22 is intermittently inserted into the support cylinder 2, the second servo motor 6, the worm 7 and the worm wheel 9.

[0023] Furthermore, by setting up bamboo joint tube 22 to protect the support cylinder 2, the second servo motor 6, the worm gear 7 and the worm wheel 9, the interference of dust and debris is reduced.

[0024] A solar panel tracking system is used in the adjustable-angle integrated solar-energy storage and charging pile. The support is a support frame 23 with open top and bottom. A vertical protective cover 24 is fixed to the top of the support base 10. The top of the protective cover 24 is dome-shaped and the bottom is cylindrical. The top of the protective cover 24 is transparent and the bottom is opaque. Two sets of photosensitive sensors 25 are fixed at a horizontal cross angle at the bottom of the protective cover 24. Each set of photosensitive sensors 25 contains two photosensitive sensors 25 arranged horizontally and correspondingly. Each photosensitive sensor 25 is located on the left, rear, right and front of the protective cover 24, respectively. Each photosensitive sensor 25 is electrically connected to the electronic control system of the integrated solar-energy storage and charging pile 1.

[0025] Furthermore, the two sets of cross-shaped photosensitive sensors 25 can sense sunlight. When the protective cover 24 is not pointing towards the sun, sunlight shines through the top of the protective cover 24 onto some of the photosensitive sensors 25. At this time, a difference in sensing data is formed between these sensors and the unilluminated photosensitive sensors 25 (usually the one opposite to the illuminated photosensitive sensor 25). The electronic control system senses this data difference and drives the first servo motor 3 and the second servo motor 6 to rotate accordingly, thereby adjusting the left-right and front-back angles of the protective cover 24 (specifically, when there is a difference in sensing data between the photosensitive sensors 25 at the front and back of the protective cover 24, the second servo motor 6 rotates accordingly, causing the support base 10 to swing the solar panel 13 back and forth; when there is a difference in sensing data between the photosensitive sensors 25 at the left and right of the protective cover 24, the first servo motor 3 rotates accordingly, causing the support base 10 to swing the solar panel 13 horizontally), until it points towards the sun, so that the solar panel 13 is directly facing the sun, achieving tracking and reaching the optimal angle for receiving sunlight, thus improving power generation efficiency.

[0026] The support frame 23 is made of transparent material. A vertical drive shaft 26 is fixed in the middle of the support frame 23. The drive shaft 26 is coaxially fixed with the shaft of the No. 3 servo motor 17. An arc-shaped brush 27 is fixed on the upper part of the support frame 23. The bristles of the arc-shaped brush 27 are in contact with the top of the upper part of the protective cover 24. A horizontal partition 28 is fixed at the bottom of the protective cover 24. The partition 28 is interlocked with the drive shaft 26 and can rotate relative to the drive shaft 26.

[0027] Furthermore, when the No. 3 servo motor 17 rotates, it drives the guard plate 12 to rotate through the transmission shaft 26 and the support frame 23, thereby using the arc-shaped brush 27 to clean the protective cover 24, thus ensuring the cleanliness of the protective cover 24, so that the photosensitive sensor 25 can receive light, that is, ensure the tracking function, while the partition 28 can reduce the entry of dust.

[0028] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
