Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a dual-axis photovoltaic support system based on intelligent tracking technology. Background Technology

[0002] With the advancement of the "dual carbon" strategy, photovoltaic power generation, as an important component of green energy, has developed rapidly. However, its efficiency is limited by the fact that traditional fixed photovoltaic brackets cannot dynamically track the sun's trajectory.

[0003] Traditional photovoltaic (PV) tracking systems suffer from significant drawbacks under low-light conditions (such as cloudy days, early morning, and dusk): insufficient light intensity leads to a substantial reduction in PV panel output power, and existing tracking systems, relying on single light intensity detection or lacking dynamic prediction capabilities, struggle to effectively adjust their angles to capture weak light energy. Furthermore, existing systems largely employ static control strategies, failing to integrate weather forecast data and thus unable to anticipate changes in cloud cover or severe weather, further reducing energy conversion efficiency under low-light conditions. While PV technology has made progress in conversion efficiency and cost control, intelligent control technology for low-light environments still faces technical bottlenecks, necessitating system optimization through the integration of sensor technology and real-time monitoring and prediction algorithms. Utility Model Content

[0004] To overcome the significant reduction in photovoltaic panel output power caused by insufficient light intensity, and the shortcomings of existing tracking systems that rely on single light intensity detection or lack dynamic prediction capabilities and are difficult to effectively adjust the angle to capture weak light energy, this utility model provides a dual-axis photovoltaic support system based on intelligent tracking technology.

[0005] The technical solution is as follows: A dual-axis photovoltaic support system based on intelligent tracking technology includes a base, a fixed seat, a first motor, a PLC controller, a support, a second motor, a mounting plate, and a photovoltaic panel; the fixed seat is rotatably connected to the base; the first motor is installed inside the base, and the output shaft of the first motor is fixedly connected to the fixed seat; the PLC controller is installed on the upper left side of the base; the support is rotatably connected to the fixed seat; the second motor is bolted to the upper left side of the fixed seat, and the output shaft of the second motor is fixedly connected to the support; the mounting plate is fixedly connected to the upper side of the support; the photovoltaic panel is installed on the upper side of the mounting plate; and a monitoring light is also included. The system comprises a photosensitive sensor, a connecting base, a telescopic rod, a protective film, a connecting ring, connecting balls, and a pulling mechanism. A photosensitive sensor is bolted to the center of the front side of the mounting plate. Several connecting bases are fixedly connected to the lower side of the mounting plate. Each connecting base is hinged to a telescopic rod. A protective film, capable of deformation, is fixedly connected between every two adjacent telescopic rods. A connecting ring is slidably connected to the upper part of the mounting base and is fixedly connected to the protective film. Several connecting balls are fixedly connected to the connecting ring and are rotatably connected to one end of the telescopic rod. A pulling mechanism is connected to the base and is connected to the connecting ring.

[0006] Preferably, the pulling mechanism includes an electric push rod and a retaining ring; an electric push rod is bolted to the front and rear sides of the base; all the telescopic parts of the electric push rods are fixedly connected to the retaining ring, and the retaining ring is slidably connected to the connecting ring.

[0007] Preferably, the device also includes a striking rod, a first spring, and a second spring; several striking rods are slidably connected to the front and rear of the bracket; a first spring is fixedly connected to the lower part of each striking rod, and one end of the first spring is fixedly connected to the bracket; a second spring is fixedly connected to the lower side of each striking rod, and one end of the second spring is fixedly connected to the protective film, and the elastic coefficient of the first spring is lower than that of the second spring.

[0008] Preferably, the striking bar is made of rubber.

[0009] Preferably, the mounting plate also includes a slide block, a slider, a cleaning plate, and a sponge block; a slide block is fixedly connected to the upper left and upper right sides of the mounting plate; a slider is slidably connected to each slide block; a cleaning plate is fixedly connected to all the sliders; and a sponge block is fixedly connected to the lower side of the cleaning plate.

[0010] The beneficial effects of this utility model are:

[0011] The PLC controller undertakes the main program control tasks, uses a monitoring photosensitive sensor to collect the light intensity difference in various directions, and calculates the optimal illumination angle through the program. Then, under the instructions of the PLC controller, it controls the first and second motors to adjust the photovoltaic panel to the optimal illumination angle. By integrating cloud cover and weather forecast data into the PLC controller monitoring system to predict changes in sunlight and correspondingly assist the system operation, it can maximize the capture of weak light energy and significantly improve the photoelectric conversion rate.

[0012] The sponge block will contact the surface of the photovoltaic panel and clean the dust on the surface of the photovoltaic panel, thereby preventing the photovoltaic panel from accumulating too much dust and affecting the absorption of sunlight. At the same time, in rainy or snowy weather, the cleaning board will scrape off the rain and snow on the surface of the photovoltaic panel, thereby preventing rain and snow from easily sticking to the surface of the photovoltaic panel over a long period of time, which would affect the subsequent absorption of sunlight by the photovoltaic panel.

[0013] In strong winds, the flat-topped pyramid formed between the telescopic pole, protective membrane, and connecting ring, with its sharp edges and slopes, can effectively divert airflow and disrupt the Karman vortex street (periodic vortex) generated under the photovoltaic panel by the strong wind. This avoids the risk of the airflow generating vortices under the photovoltaic panel when strong winds blow, causing pressure changes that would make the tilted photovoltaic panel more susceptible to being lifted by the wind, thus increasing the risk of the photovoltaic panel falling off or being blown away.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

The PLC controller 4 is installed on the upper left side of the base 1. The bracket 5 is rotatably connected to the fixed seat 2. The second motor 6 is bolted to the upper left side of the fixed seat 2, and the output shaft of the second motor 6 is fixedly connected to the bracket 5. The mounting plate 7 is fixedly connected to the upper side of the bracket 5. The photovoltaic panel 8 is installed on the upper side of the mounting plate 7.

[0024] It also includes a monitoring photosensitive sensor 9, a connecting seat 10, a telescopic rod 11, a protective film 12, a connecting ring 13, a connecting ball 14, and a pulling mechanism; the monitoring photosensitive sensor 9 is bolted to the center of the front side of the mounting plate 7; four connecting seats 10 arranged in a matrix are fixedly connected to the lower side of the mounting plate 7; each connecting seat 10 is hinged to a telescopic rod 11; a protective film 12 is fixedly connected between every two adjacent telescopic rods 11, and the protective film 12 has the ability to deform; a connecting ring 13 is slidably connected to the upper part of the fixed seat 2, and the connecting ring 13 is fixedly connected to the protective film 12; four connecting balls 14 arranged in a matrix are fixedly connected to the connecting ring 13, and the connecting balls 14 are rotatably connected to one end of the telescopic rod 11; a pulling mechanism is connected to the base 1, and the pulling mechanism is connected to the connecting ring 13.

[0025] The pulling mechanism includes an electric push rod 21 and a fixing ring 22; an electric push rod 21 is bolted to the front and rear sides of the base 1; all the telescopic parts of the electric push rods 21 are fixedly connected to the fixing ring 22, and the fixing ring 22 is slidably connected to the connecting ring 13.

[0026] It also includes a striking rod 31, a first spring 32 and a second spring 33; two striking rods 31 are slidably connected to the front and rear of the bracket 5, which are distributed in a front-to-back manner; a first spring 32 is fixedly connected to the lower part of each striking rod 31, and one end of the first spring 32 is fixedly connected to the bracket 5; a second spring 33 is fixedly connected to the lower side of each striking rod 31, and one end of the second spring 33 is fixedly connected to the protective film 12, and the elastic coefficient of the first spring 32 is lower than that of the second spring 33.

[0027] The striking rod 31 is made of rubber to prevent damage to the bracket 5 when the striking rod 31 strikes the bracket 5.

[0028] It also includes a slide block 41, a slider 42, a cleaning plate 43, and a sponge block 44; a slide block 41 is fixedly connected to the upper left and upper right sides of the mounting plate 7; a slider 42 is slidably connected to each slide block 41; a cleaning plate 43 is fixedly connected to all the sliders 42; a sponge block 44 is fixedly connected to the lower side of the cleaning plate 43.

[0029] When using this dual-axis photovoltaic support system based on intelligent tracking technology, firstly, the intensity of sunlight is detected by the monitoring photosensitive sensor 9, and the detected data is transmitted to the PLC controller 4 for analysis and comparison with the preset rated light intensity. If the current light intensity does not match the rated light intensity, the PLC controller 4 will control the first motor 3 to drive the fixed base 2 to rotate. The support 5 and its connected parts will rotate synchronously with the fixed base 2. At the same time, the PLC controller 4 will also control the second motor 6 to drive the support 5 to rotate clockwise or counterclockwise. The mounting plate 7, photovoltaic panel 8, monitoring photosensitive sensor 9, connecting base 10, striking rod 31, first spring 32, second spring 33, slide 41, slider 42, cleaning plate 43, and sponge block 44 will rotate synchronously with the support 5. During this process, due to the action of the connecting ring 13, one end of the telescopic rod 11 will rotate on the connecting ball 14, while the other end of the telescopic rod 11 will rotate on the connecting ball 14. When the mounting base 10 rotates, the corresponding telescopic rod 11 and protective film 12 will stretch and contract, and the photovoltaic panel 8 will change from a horizontal state to a tilted state. It should be noted that the PLC controller 4 can drive the second motor 6 to drive the bracket 5 to rotate according to the light intensity and the angle of the sun, thereby adjusting the tilt angle of the photovoltaic panel 8, so that the photovoltaic panel 8 can obtain the maximum light energy and effectively utilize solar energy. It is explained that by driving the fixed base 2 to rotate through the first motor 3, and at the same time cooperating with the second motor 6 to drive the bracket 5 to rotate, the photovoltaic panel 8 can be adjusted in all directions, so as to ensure that the photovoltaic panel 8 always faces the sun.

[0030] Thus, the PLC controller 4 undertakes the main program control tasks, uses the monitoring photosensitive sensor 9 to collect the light intensity difference in various directions, and calculates the optimal illumination angle through the program. Then, under the instructions of the PLC controller 4, it controls the first motor 3 and the second motor 6 to adjust the photovoltaic panel 8 to the optimal illumination angle. By integrating cloud cover and weather forecast data into the monitoring system of the PLC controller 4 to predict changes in sunlight and correspondingly assist the system operation, it can maximize the capture of weak light energy and significantly improve the photoelectric conversion rate. It should be noted that in order to make the photovoltaic panel 8 better obtain light energy, the monitoring photosensitive sensor 9 will detect the intensity of sunlight every twenty minutes to ensure that the current light intensity is consistent with the rated light intensity, thereby ensuring the efficient utilization of sunlight by the photovoltaic panel 8.

[0031] Meanwhile, as the second motor 6 drives the bracket 5 to rotate clockwise or counterclockwise, the slide block 41 will also change from a horizontal state to an inclined state, so the slider 42 will slide on the inclined slide block 41. The cleaning plate 43 and the sponge block 44 move synchronously with the slider 42. During this process, the sponge block 44 will contact the surface of the photovoltaic panel 8 and clean the dust on the surface of the photovoltaic panel 8, thereby preventing the photovoltaic panel 8 from having too much dust attached to the surface, which would affect the absorption of sunlight by the photovoltaic panel 8. At the same time, when it is rainy or snowy, the cleaning plate 43 will scrape off the rain and snow on the surface of the photovoltaic panel 8, thereby preventing rain and snow from sticking to the surface of the photovoltaic panel 8 for a long time, which would affect the absorption of sunlight by the photovoltaic panel 8 in the future.

[0032] Simultaneously, the arrangement of the telescopic rod 11, the protective membrane 12, and the connecting ring 13 creates a flat-topped pyramidal structure, as shown below. Figure 5 As shown, in strong winds, the flat-topped pyramid formed between 11, the protective film 12, and the connecting ring 13, with its sharp edges and slopes, can effectively divert airflow and disrupt the Karman vortex street (periodic vortex) generated under the photovoltaic panel 8 by the strong wind. This avoids the possibility of vortices being generated under the photovoltaic panel 8 by the airflow when strong winds blow, leading to pressure changes and making the tilted photovoltaic panel more susceptible to being lifted by the wind, thus increasing the risk of the photovoltaic panel 8 falling off or being blown away. At the same time, when there is strong wind and sun showers, the electric push rod 21 can be controlled to move the fixing ring 22 downwards, and the connecting ring 13 and the connecting ball 14 move downwards synchronously with the fixing ring 22. During this process, because the protective film 12 has deformation capabilities, Furthermore, the telescopic rod 11 will deflect downward on the connecting seat 10, thereby stretching the telescopic rod 11 and the protective membrane 12, and thus the tilt of the protective membrane 12 will gradually increase. During this process, the protective membrane 12 will pull the striking rod 31 downward through the second spring 33, the first spring 32 will be compressed, and then the second spring 33 will be stretched. Subsequently, the flat-topped pyramid formed between the telescopic rod 11, the protective membrane 12 and the connecting ring 13 will be stretched, thereby further optimizing the airflow guidance effect and improving the wind resistance performance by stretching the flat-topped pyramid.

[0033] It should be noted that when strong winds blow against the protective film 12, due to its deformation capability, the protective film 12 will thrash back and forth. That is, the strong wind will slightly compress the protective film 12, causing it to dent inwards. During this process, the compressed first spring 32 and the stretched second spring 33 will gradually return to their normal state. Consequently, the striking rod 31 will move upwards on the support 5, striking the support 5. This will subject the photovoltaic panel 8 on the support 5 to a vibration force, causing rainwater adhering to the photovoltaic panel 8 to flow off. This prevents a small amount of rainwater from adhering to the surface of the photovoltaic panel 8 after a solar rain. Since rainwater refracts sunlight, the amount of sunlight absorbed by the photovoltaic panel 8 will decrease, thus affecting the power generation of the photovoltaic panel 8. The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
