In this embodiment, the user inputs the position information of the local sun at each time point into the controller 6, and the controller 6 calculates the required rotation angle of the photovoltaic panel 5 at each time period according to the input position information of the sun at each time point; of course, the position of the sun at each time point is different according to the season, for example, in winter, sunrise, evening, sunset, and early, the illumination time is short, in summer, sunrise, early, sunset, late, and the illumination time is long, so when inputting the position information of the sun at each time point into the controller 6, the seasonality also needs to be considered, and usually three modes, a spring/autumn mode, a summer mode, and a winter mode, are set, and of course, if it is desired to be more accurate, twelve modes can be input according to the month, and the selection is performed by the user according to the needs of the client. After a user inputs position information of the sun at each time point into the controller 6, the time relay 7 transmits the time information at the time point into the controller 6, wherein the time information comprises a month, a day and the time point, and the controller 6 matches the position information of the sun at the time point according to the time information transmitted by the time relay 7 and then converts the position information into an angle required by the photovoltaic panel 5 to rotate at the time point; finally, the controller 6 controls the driving assembly to drive the photovoltaic panel 5 to rotate to a corresponding angle. Wherein each mode comprises a point of time of operation of the photovoltaic panel 5, for example in summer mode, the photovoltaic panel 5 is operated for a long time due to the long sunshine duration, and correspondingly in winter mode, the photovoltaic panel 5 is operated for a short time due to the short sunshine duration. Meanwhile, when the photovoltaic panel 5 finishes working, the controller 6 controls the driving assembly to drive the photovoltaic panel 5 to reset, when the sun rises on the next day, sunlight can vertically irradiate on the photovoltaic panel 5, and of course, when the sun rises on the next day, the controller 6 controls the driving assembly to drive the photovoltaic panel 5 to reset. Because of the nature of the sun east rising west fall, when the whole device is placed in the corresponding position, it should be ensured that the length direction of the main shaft 4 is parallel to the north-south direction, so that the photovoltaic panel 5 can be rotated in the east-west direction. The device combines the position information of the sun at each time point, the real-time point is transmitted to the controller 6 by the time relay 7, and then the controller 6 controls the driving mechanism to drive the photovoltaic panel 5 to rotate, so that the sunlight can be directly emitted onto the photovoltaic panel 5, and the power generation efficiency of the photovoltaic panel 5 is improved.
Referring to fig. 1, the driving assembly includes a stepping motor 8, a reduction gearbox 9, a driving gear 10, a driven gear 11 and a chain 12, the stepping motor 8 and the reduction gearbox 9 are respectively and fixedly connected to the base 1, the stepping motor 8 is in transmission connection with the reduction gearbox 9, the driving gear 10 is fixedly connected to an output shaft of the reduction gearbox 9, the driven gear 11 is connected to the spindle 4, the chain 12 is sleeved between the driving gear 10 and the driven gear 11, and the stepping motor 8 is electrically connected to the controller 6.
In this embodiment, the operating principle of the driving assembly is that the controller 6 transmits the rotating direction and the rotating angle of the stepping motor 8 to the stepping motor 8, the stepping motor 8 starts to rotate after receiving a command, and the reduction gearbox 9 drives the driving gear 10 to rotate, so as to drive the driven gear 11 and the spindle 4 to rotate through the chain 12, and when the spindle 4 rotates, the turntable 3 and the photovoltaic panel 5 are driven to rotate, so that the photovoltaic panel 5 rotates to a corresponding position.
Referring to fig. 1, the maximum rotation angle of the turntable 3 is 120 °.
In the present embodiment, since the sunlight is small at the beginning of sunrise and at the end of sunset, the power generation efficiency of the photovoltaic panel 5 is not high, and therefore, the photovoltaic panel 5 does not start to operate at this stage. Through a plurality of tests, when the rotation angle of the turntable 3 is set to be 120 degrees, the total power generation amount of the photovoltaic panel 5 is the highest every day.
Referring to fig. 1 and 2, a first pressure sensor 13 and a second pressure sensor 14 are arranged on the main shaft 4, an included angle formed by a connecting line between the first pressure sensor 13 and a central point of the main shaft 4 and a connecting line between the second pressure sensor 14 and a central point of the main shaft 4 is 120 °, a pressing block 15 is arranged on the connecting column 2, and when the main shaft 4 rotates to one of limit angles, the pressing block 15 abuts against the first pressure sensor 13; when the main shaft 4 rotates to another limit angle, the pressing block 15 abuts against the second pressure sensor 14.
In this embodiment, when the first pressure sensor 13 abuts against the pressing block 15, it is described that the spindle 4 drives the photovoltaic panel 5 to rotate to one of the limit positions, at this time, the first pressure sensor 13 directly cuts off the power supply of the stepping motor 8, which aims to prevent the controller 6 from breaking down, after the photovoltaic panel 5 rotates to the limit position, the stepping motor 8 continues to drive the photovoltaic panel 5 to rotate, and after the photovoltaic panel 5 rotates to a certain position, the photovoltaic panel 5 collides with the connecting column 2, which causes damage to the photovoltaic panel 5. In the same way, the second pressure sensor 14 acts on the first pressure sensor 13 in a consistent manner, all in order to prevent the controller 6 from breaking down, and after the photovoltaic panel 5 rotates to the extreme position, the stepping motor 8 is enabled to continue to drive the photovoltaic panel 5 to rotate, so that the photovoltaic panel 5 is damaged.
Referring to fig. 1, 3 and 4, an angle measuring assembly is arranged between the rotary table 3 and the connecting column 2, the angle measuring assembly includes a slide 16 and a pressure detector, the slide 16 is fixedly connected to an end surface of the rotary table 3 along a circumferential direction, the slide 16 faces the connecting column 2, and a distance between one side of the slide 16 facing the connecting column 2 and the rotary table 3 decreases from one end of the slide 16 to the other end of the slide 16; pressure detector includes casing 17, telescopic link 18, third pressure sensor 19 and spring 20, casing 17 fixed connection be in on the spliced pole 2, be equipped with the first passageway 21 and the second passageway 22 that are linked together in the casing 17, first passageway 21 is followed casing 17 is close to 3 one end of carousel stretches out, telescopic link 18 sliding connection be in first passageway 21, just one of them one end of telescopic link 18 with slide 16 offsets and leans on, third pressure sensor 19 is placed in the second passageway 22, the other end of telescopic link 18 stretch into to in the second passageway 22 with third pressure sensor 19 fixed connection, spring 20 fixed connection be in third pressure sensor 19 with between the bottom of second passageway 22, third pressure sensor 19 with controller 6 electricity is connected.
In this embodiment, in the process that the controller 6 controls the driving assembly to drive the photovoltaic panel 5 to rotate, a certain deviation exists, and the deviation of the photovoltaic panel 5 is increased in the day and the month. The effect of the angle measurement assembly is that the position of the photovoltaic panel 5 can be corrected in real time. Specifically, since the photovoltaic panel 5 is fixedly connected to the turntable 3, the rotation angle of the turntable 3 corresponds to the position of the photovoltaic panel 5. When the rotating disc 3 is located at different positions, the positions of the telescopic rods 18 abutted against the slide ways 16 are also different, and because the distance between one side of the slide way 16 facing the connecting column 2 and the rotating disc 3 is gradually reduced from one end of the slide way 16 to the other end of the slide way 16, when the telescopic rods 18 are abutted against different positions of the slide way 16, the extending distances of the telescopic rods 18 are also different, so that the pressure applied to the third pressure sensors 19 is also different, the weight applied by the third pressure sensors 19 is transmitted to the controller 6 in real time, the extending distances of the telescopic rods 18 are calculated through different weights applied to the third pressure sensors 19, the positions of the slide ways 16 abutted against the telescopic rods 18 are calculated according to the extending distances of the telescopic rods 18, and further the actual rotating angles of the photovoltaic panel 5 are calculated. When calculating the relationship between the output pressure of the third pressure sensor 19 and the photovoltaic panel 5, the photovoltaic panel 5 may be driven to move to a corresponding angle, and then the pressure of the third sensor 19 is recorded, for example, when the photovoltaic panel 5 rotates to 5 °, the output pressure of the third sensor 19 is a, when the photovoltaic panel 5 rotates to 10 °, the output pressure of the third sensor 19 is b, several sets of data are measured, and then the relationship between the output pressure of the third pressure sensor 19 and the photovoltaic panel 5 is calculated. When the deviation between the actual rotation angle of the photovoltaic panel 5 and the theoretical rotation angle of the photovoltaic panel 5 at the real-time point of the time relay 7 by the controller 6 is large, the controller 6 controls the driving assembly to drive the photovoltaic panel 5 to rotate, and the theoretical rotation angle of the photovoltaic panel 5 is corrected, so that the real-time rotation angle of the photovoltaic panel 5 is consistent with the theoretical rotation angle of the photovoltaic panel 5; for example, at 3 pm, the theoretical rotation angle of the photovoltaic panel 5 recorded by the controller 6 is 100 °, but at this time, the actual rotation angle of the photovoltaic panel 5 calculated by the output pressure of the third sensor 19 is 110 °, and at this time, the controller 6 controls the driving assembly to drive the photovoltaic panel 5 to rotate to 100 °.
Referring to fig. 4, a plurality of limiting rods 23 are fixedly connected to the second channel 22 along the length direction of the second channel 22, and the limiting rods 23 are respectively close to the side surfaces of the third pressure sensor 19.
In the present embodiment, the limiting rod 23 is used to stabilize the moving direction of the third pressure sensor 19, and prevent the angle deviation of the third pressure sensor 19 from being too large, which causes the deviation of the force applied by the telescopic rod 18 on the third pressure sensor 19.
Referring to fig. 1, two oil cylinders are fixedly connected to the two rotating discs 3, each oil cylinder includes a cylinder body 24 and a piston rod 25, the piston rod 25 is slidably connected in the cylinder body 25, an accommodating cavity 26 is formed in an end of the rotating disc 3 facing the photovoltaic panel 5, the cylinder body 24 is fixedly connected in the accommodating cavity 26, the end of the piston rod 25 extends out of the cylinder body 25 and is hinged to the bottom of the photovoltaic panel 5, and the oil cylinders are electrically connected to the controller 6.
In this embodiment, the oil cylinder is used for adjusting the north-south angle of the photovoltaic panel 5. Due to the problem of the irradiation angle of the sunlight, particularly in summer solstice and winter solstice, the irradiation angle deviation of the sunlight is the largest, so that the oil cylinder is used for adjusting the angle of the photovoltaic panel 5 in the north-south direction, and the sunlight can directly irradiate on the photovoltaic panel 5. Therefore, the user can adjust the north and south angles of the photovoltaic panel 5 by the oil cylinder at intervals, for example, at intervals of one month, or at intervals of one quarter. The oil cylinder is used for adjusting the north-south angle of the photovoltaic panel 5, specifically, the north-south angle of the photovoltaic panel 5 is controlled by controlling the stretching amount of the two piston rods 25, when the stretching amounts of the two piston rods 25 are consistent, the north-south angle of the photovoltaic panel 5 is 0 degree, and when the stretching amount of the piston rod 25 positioned on the south side is smaller than that of the piston rod 25 positioned on the north side, the photovoltaic panel 5 is deviated to the south, wherein the specific deviation angle is determined by the difference value of the stretching amounts of the two piston rods 25, the larger the difference value is, the larger the deviation angle is, the smaller the difference value is, and the smaller the deviation angle is; similarly, when the amount of expansion of the piston rod 25 located in the north side is smaller than the amount of expansion of the piston rod 25 located in the south side, the photovoltaic panel 5 is biased to the north side.
Referring to fig. 1, the time relay 7 sends time information to the controller 6 every hour.
In the present embodiment, the time relay 7 sends time information to the controller 6 once an hour has elapsed, that is, the controller 6 will adjust the angle of the photovoltaic panel 5 once an hour has elapsed. If the time for adjusting the angle of the photovoltaic panel 5 by the two adjacent controllers 6 is too short, the electricity consumption cost of the driving assembly is increased; if the angle of the photovoltaic panel 5 is adjusted by the controller 6 twice in a row for too long time, the efficiency of the photovoltaic panel 5 receiving sunlight will be lower and lower as time goes on.
Referring to fig. 1, the area of the base 1 is larger than that of the photovoltaic panel 5, and a plurality of balancing weights 27 are uniformly placed at the edge of the base 1.
In this embodiment, the area of the base 1 is larger than the area of the photovoltaic panel 5, and a plurality of counterweights 27 are uniformly placed at the edge of the base 1, all with the purpose of increasing the stability of the whole device. Especially the device is usually put on spacious ground, often can touch strong wind weather, increases the stability of whole device, can guarantee that whole device can not be blown by strong wind the emergence displacement. If the angle of the whole device is deviated, the generating efficiency of the photovoltaic panel 5 is affected.
