Description

Technical Field

[0001] The present invention relates to the technical field of solar power generation, and in particular to a dual-axis automatic tracking solar power generation device. Background Art

[0002] The rapid rise of global science and technology has led us to a new era of clean energy development. The three major energy types that currently dominate new energy are solar energy, wind energy, and nuclear energy [5]. The trajectory of solar power generation technology is actually a foreshadowing of the future development path of the global energy sector. It is gradually showing its characteristics as a clean and recyclable energy technology with the greatest development potential. Among the many solar power generation methods, photovoltaic power generation and thermal power generation are the most mainstream.

[0003] A solar panel is configured with multiple solar cells, but the overall efficiency is usually not as good as that of a single cell. The main reason is that the panel may be affected by the external environment and only part of it is exposed to the sun. In this case, the photoelectric conversion in the panel is not balanced, and the shaded part needs to transfer energy to the part that normally receives light. This situation leads to high resistance and voltage drop inside some solar panels. Over time, this can cause a lot of heat to be generated, which damages the cells. This heat leaves spots in the panel, which shortens the service life of the panel and can even cause serious damage to the entire photovoltaic system. Therefore, in order to prevent this situation, bypass diodes are often used to avoid blockage and power loss caused by solar cells in the enclosed area of ​​the panel, which in turn damages the solar cells in the series circuit.

[0004] In addition to the research on the battery itself, photovoltaic power generation also plays a key role in solar power generation. The construction and research of the system model of photovoltaic brackets, the optimization design of the structure, the selection of materials, etc. are highly valued by relevant scholars and the industry. In order to meet the installation and use needs of different places, the types of solar photovoltaic brackets on the market have begun to increase gradually. When choosing, users can choose the most suitable bracket according to the local environmental characteristics. If you want to improve the utilization rate of solar energy, you can choose a bracket equipped with a tracking device, which can track the position of the sun in real time to further improve the power generation efficiency.

[0005] In the prior art, the axis tracking system of a conventional solar power generation device is a system that can rotate on an axis in one dimension, allowing the photovoltaic panel to receive sunlight at the most suitable angle. Although it only tracks the sun in one direction, this means that in a unit of time, only part of the sunlight can shine vertically on the photovoltaic panel, while most of the other light is mostly oblique. Therefore, the tracking accuracy of the single-axis tracking device is not high enough, resulting in a relatively low solar energy collection efficiency. In addition, the solar panel has a large area and is easily damaged in an environment with high wind speed, making it unsafe to use. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 6 A dual-axis automatic tracking solar power generation device comprises a bottom plate 1, a box body 2 is fixedly mounted on the upper surface of the bottom plate 1, a lifting mechanism 3 is fixedly mounted on the upper and lower inner walls of the box body 2 near the left position, a first mounting frame 4 is fixedly mounted on the upper surface of the lifting mechanism 3, a horizontal rotation mechanism 5 is mounted on the upper side wall of the first mounting frame 4, a second mounting frame 6 is fixedly mounted on the upper surface of the horizontal rotation mechanism 5, a vertical rotation mechanism 7 is arranged on the rear side wall of the second mounting frame 6, and a fixing plate 8 is fixedly mounted on the rear side surface of the output shaft of the vertical rotation mechanism 7 A solar panel assembly 9 is fixedly installed on the left side of the fixing plate 8, and a protective mechanism 10 is fixedly installed on the upper surface of the bottom plate 1 corresponding to the solar panel assembly 9. A battery 11 is installed on the lower inner wall of the box body 2 near the left side, and a mounting plate 12 is fixedly installed on the front and rear inner walls of the box body 2 near the upper side. A control mechanism 13 is fixedly installed on the upper surface of the mounting plate 12, and the control mechanism 13 is wirelessly connected to the terminal device 14. A box door 15 is hingedly installed on the right side of the box body 2, and the box door 15 is locked and fixed to the box body 2 by a hidden lock 16.

[0030] Specifically, the lifting mechanism 3 includes an electric linear module 301, a support rod 302 and a rubber sealing ring 303. The electric linear module 301 is fixedly installed between the upper and lower inner walls of the box 2. The support rod 302 is fixedly installed on the right side of the slide of the electric linear module 301. The upper surface of the support rod 302 is fixedly connected to the lower surface of the first mounting frame 4. A rubber sealing ring 303 is fixedly installed on the upper side wall of the box 2 corresponding to the support rod 302.

[0031] In this embodiment, the slide of the electric linear module 301 drives the support rod 302 to move up and down, so that the support rod 302 moves up and down to achieve the effect of adjusting the height of the solar panel assembly 9. The rubber sealing ring 303 seals the support rod 302 and the upper side wall of the box body 2 to improve the waterproof performance.

[0032] Specifically, the horizontal rotation mechanism 5 includes a reduction motor 501, a touch block 502 and a travel limit switch 503. The reduction motor 501 is fixedly mounted on the upper inner wall of the first mounting frame 4. The upper surface of the output shaft of the reduction motor 501 is fixedly connected to the lower surface of the second mounting frame 6. The touch block 502 is arranged on the right side of the output shaft of the reduction motor 501. The travel limit switches 503 are arranged at the front and rear positions on the left side of the upper surface of the first mounting frame 4.

[0033] In this embodiment, the output shaft of the reduction motor 501 drives the second mounting frame 6 to rotate in the horizontal direction, so as to adjust the horizontal direction of the solar panel assembly 9. At the same time, the output shaft of the reduction motor 501 drives the touch block 502 to rotate. When the touch block 502 contacts the front and rear travel limit switch 503, the reduction motor 501 stops rotating, and then starts to rotate in the opposite direction, so as to limit the horizontal rotation angle of the solar panel assembly 9. The reduction motor 501 drives the solar panel assembly 9 to rotate in the horizontal direction within a range of 340 degrees. The reduction motor 501 uses a 5840-31ZY worm gear reduction motor as a core component. The 5840-31ZY worm gear reduction motor is an angle servo drive. Since the design requires that the solar panel can receive sunlight with the best incident angle in real time and accurately, the 5840-31ZY worm gear reduction motor is selected as the power source.

[0034] Specifically, the vertical rotation mechanism 7 has the same structure as the horizontal rotation mechanism 5 .

[0035] In this embodiment, the output shaft of the vertical rotation mechanism 7 drives the solar panel assembly 9 to rotate in the vertical direction through the fixed plate 8. The vertical rotation mechanism 7 drives the solar panel assembly 9 to rotate in the vertical direction within a range of one hundred and twenty degrees.

[0036] Specifically, the protective mechanism 10 includes a vertical plate 101, a sponge block 102, a slot 103 and a wind speed sensor 104. The vertical plate 101 is fixedly installed on the upper surface of the base plate 1. The sponge blocks 102 are fixedly installed on the right side of the vertical plate 101 and the left side of the box 2, and a slot 103 is formed between the left and right sponge blocks 102. The fan sensor is installed on the upper surface of the box 2.

[0037] In this embodiment, the wind speed sensor 104 monitors the wind speed and feeds back the information to the control mechanism 13. The single chip microcomputer 131 in the control mechanism 13 receives the information. When the fan reaches the set value, the solar panel assembly 9 is reset and kept vertically above the slot 103. The lifting mechanism 3 drives the solar panel assembly 9 to reset downward, so that the solar panel assembly 9 is inserted into the slot 103, and the sponge block 102 protects the solar panel assembly 9.

[0038] Specifically, the control mechanism 13 includes a single-chip microcomputer 131, a solar trajectory calculation module 132, a wireless communication module 133, an MPPT controller 134, a display screen 135 and a patch photosensor 136. The single-chip microcomputer 131, the solar trajectory calculation module 132, the wireless communication module 133 and the MPPT controller 134 are installed on the upper surface of the mounting plate 12, the inner wall of the box body 2 and the box door 15. The display screen 135 is embedded on the box door 15 corresponding to the MPPT controller 134. The patch photosensor 136 is fixedly installed on the upper surface of the solar panel assembly 9. The single-chip microcomputer 131 is electrically connected to the solar trajectory calculation module 132, the wireless communication module 133, the MPPT controller 134, the display screen 135 and the patch photosensor.

[0039] In this embodiment, the patch photosensitive sensor 136 monitors the light intensity. When the light intensity is greater than the set value, the photoelectric tracking method is used to check the light through the patch photosensitive sensor 136, and the information is fed back to the single-chip microcomputer 131. The single-chip microcomputer 131 rotates the horizontal rotation mechanism 5 and the vertical rotation mechanism 7 to adjust the direction and angle of the solar panel assembly 9. When the light is poor on a cloudy day, the patch photosensitive sensor 136 detects that the rigid line intensity is less than the set value. The single-chip microcomputer 131 uses the information of the sun trajectory calculation module 132. Before use, the terminal device 14 inputs the longitude and latitude of the solar panel assembly 9. The sun trajectory calculation module 132 rotates the single-chip microcomputer 131 through the horizontal rotation mechanism 5 and the vertical rotation mechanism 7 according to the calculated information to adjust the direction and angle of the solar panel assembly 9. The single-chip microcomputer 131 uses Arduino Nano single chip microcomputer, MPPT controller 134 adopts STM32F103CBT6 version synchronous BUCK solar controller with excellent performance and comprehensive functions, which is an ideal choice for high-efficiency solar energy management. The controller supports a variety of battery types and can adapt to a wide range of application scenarios. Its load output control function is very flexible, supporting manual, automatic, time control and light control modes, so that it can intelligently adjust the power output according to the voltage of the photovoltaic panel. In addition, it also has comprehensive safety protection measures, including over-temperature, over-voltage, over-current and anti-reverse flow protection, to ensure the safety and reliability of system operation. This solar controller is an efficient solution that combines high performance, multi-function and safety. The display screen 135 can display the key parameters of the system, the real-time voltage and current of the solar panel, and the real-time voltage and current charging and discharging of the battery 11 in real time, so that the user can monitor the operating status of the controller at any time. A number of small integrated circuit chips are arranged near the display screen 135. These chips include the main controller and other control logic elements, which are responsible for running the MPPT algorithm, processing input data, and controlling the overall working status of the circuit.

[0040] Specifically, the patch photosensor 136 is integrated by five pairs of patch photoresistor tubes, and the patch photoresistor tubes are respectively located at the top, bottom, left, right and center of the circle.

[0041] In this embodiment, after selecting the photoelectric tracking mode, the patch photosensitive sensor 136 detects the current sunlight intensity. If the light intensity is insufficient and is not caused by human factors, the system determines that it is currently cloudy or night, and enters other modes or standby mode. If the light intensity exceeds the preset value, first, the system enters the initialization phase after startup and starts running. Through the patch photosensitive sensor 136, the system detects the light intensity of the surrounding environment in real time. The patch photosensitive sensor 136 adjusts its resistance value according to the change of light intensity, and the system determines the current lighting conditions by reading these resistance values. When the detected light intensity is greater than the preset threshold, the system further analyzes the direction of the light source and prepares to adjust the position. Next, the system compares the photoresistor readings in the up and down and left and right directions respectively to determine the specific position of the light source. For the up and down directions, the system determines the running direction of the vertical rotation mechanism 7 by comparing the readings of photoresistors No. 1 and No. 2: If the light intensity of photoresistor No. 1 is greater than that of photoresistor No. 2, it indicates that the light source is located above, and the system drives the vertical rotation mechanism 7 to rotate forward; otherwise, the vertical rotation mechanism 7 is driven to reverse. For the left and right directions, the system determines the running direction of the horizontal rotation mechanism 5 by comparing the readings of photoresistors No. 3 and No. 4: if the light intensity of photoresistor No. 3 is greater than that of photoresistor No. 4, it indicates that the light source is on the left, and the system drives the horizontal rotation mechanism 5 to rotate forward; otherwise, it drives the horizontal rotation mechanism 5 to rotate reversely. In addition, the system also uses photoresistor No. 5 at the center of the circle to detect whether the device is aligned with the light source. If the light intensity detected by the photoresistor is equal to or greater than that in other directions, the system will keep the motor from rotating, indicating that the device is in the best position.

[0042] Specifically, the terminal device 14 can be a mobile phone APP, a computer or a host computer.

[0043] In this embodiment, a mobile phone APP, a computer or a host computer can perform various settings on the MPPT controller 134 and view the information of the solar panel assembly 9 and the battery 11 through the terminal device 14.

[0044] The working principle of the present invention is as follows: when in use, the lifting mechanism 3 is opened by the single chip microcomputer 131 in the control mechanism 13, and the slide of the electric linear module 301 in the lifting mechanism 3 drives the support rod 302 to move upward, so that the support rod 302 drives the solar panel assembly 9 to move upward through the first mounting frame 4, the horizontal rotation mechanism 5, the second mounting frame 6, the vertical rotation mechanism 7 and the fixed plate 8, and the light intensity is monitored by the patch photosensitive sensor 136. When the light intensity is greater than the set value, the photoelectric tracking method is used to check the light through the patch photosensitive sensor 136. The information is fed back to the single chip microcomputer 131, and the single chip microcomputer 131 rotates the horizontal rotation mechanism 5 and the vertical rotation mechanism 7. The output shaft of the reduction motor 501 in the horizontal rotation mechanism 5 drives the second mounting frame 6 to rotate in the horizontal direction. The second mounting frame 6 drives the fixing plate 8 to rotate in the horizontal direction through the vertical rotation mechanism 7. The fixing plate 8 drives the solar panel assembly 9 to rotate in the horizontal direction. The vertical rotation mechanism 7 drives the solar panel assembly 9 to tilt in the vertical direction through the fixing plate 8, and adjusts the direction and angle of the solar panel assembly 9 so that the solar panel assembly 9 can be directed to the sunlight. Line tracking, when the light is poor on a cloudy day, the patch photosensitive sensor 136 detects that the rigid line strength is less than the set value, and the single chip 131 uses the information of the solar trajectory calculation module 132. Before use, the terminal device 14 inputs the longitude and latitude of the solar panel assembly 9. The solar trajectory calculation module 132 rotates the single chip 131 through the horizontal rotation mechanism 5 and the vertical rotation mechanism 7 according to the calculated information, adjusts the direction and angle of the solar panel assembly 9, monitors the light intensity, and selects the corresponding photoelectric tracking and solar trajectory tracking, combines photoelectric tracking and solar trajectory tracking, takes advantage of each other's strengths and makes up for the shortcomings of a single method, has a dual-axis automatic tracking function, can adjust the solar panel assembly 9 in the horizontal and vertical directions, has higher power generation efficiency, extends the service life of the solar panel assembly 9, and sends cooling to the single chip 131 wirelessly through the terminal device 14. The single chip 131 can set multiple control modes such as light control mode and time control mode through the MPPT controller 134. Users do not need to manually operate the opening and closing of the load equipment, but realize automatic control through a preset schedule, saving time costs for management and operation. This automatic control not only improves the overall efficiency of the system, but also enhances the user experience, making the use of the solar energy system more convenient and reliable. The wind speed is monitored by the wind speed sensor 104 in the protection mechanism 10, and the information is fed back to the control mechanism 13. The single-chip microcomputer 131 in the control mechanism 13 receives the information. When the fan reaches the set value, the solar panel assembly 9 is reset to remain vertically above the slot 103. The lifting mechanism 3 drives the solar panel assembly 9 to reset downward, so that the solar panel assembly 9 is inserted into the slot 103, and the sponge block 102 protects the solar panel assembly 9, so that the solar panel assembly 9 is not easily damaged in special weather.

[0045] To sum up, the dual-axis automatic tracking solar power generation device has a dual-axis automatic tracking function, can adjust the solar panel assembly 9 in the horizontal and vertical directions, and combines photoelectric tracking and solar trajectory tracking to complement each other, make up for the shortcomings of a single method, and have higher power generation efficiency. It also increases the protection function of the solar panel assembly 9, making it less likely to be damaged in special weather.
