DETAILED DESCRIPTION

[0020] An integrated photovoltaic power generation management system includes a stretching and gathering structure and a management and control structure. There are multiple sets of the stretching and gathering structure and the management and control structure, and each set has the same structure and function. Only one set is used as an example below. like Figure 1 and Figure 2 As shown, the stretching and gathering structure includes two columns 1, and the columns 1 are opposite to each other. A fixed plate 2 is fixed between the columns 1, and a sliding groove 3 is opened in the middle of the fixed plate 2. The sliding groove 3 is in a horizontal state. A sliding column 4 is provided in the sliding groove 3. Photovoltaic panels 5 are evenly arranged on the surface of one side of the sliding groove 3, and gears 15 are evenly arranged on the surface of the other side of the sliding groove 3. The side surface of the photovoltaic panel 5 is fixedly connected to one end of the sliding column 4, and the center surface of the gear 15 is fixedly connected to the other end of the sliding column 4.

[0021] The surface of the sliding column 4 is also provided with an upper rotating shaft 6 and a lower rotating shaft 7, which are located between the photovoltaic panel 5 and the fixed plate 2. The upper rotating shaft 6 and the lower rotating shaft 7 can rotate around the surface of the sliding column 4. The surface of the upper rotating shaft 6 is fixed with an upper fork plate 8, and the surface of the lower rotating shaft 7 is fixed with a lower fork plate 9. The upper fork plate 8 and the lower fork plate 9 are placed obliquely and crosswise, and the two ends of the upper fork plate 8 and the lower fork plate 9 are hinged.

[0022] A rotating shaft A 10 and a rotating shaft B 11 are provided on the surface of one of the columns 1. The rotating shaft A 10 and the rotating shaft B 11 are arranged in concentric circles. The lower fork plate 9 is fixedly connected to the side of the rotating shaft B 11. The upper fork plate 8 and the driving rod 13 are fixedly connected to the side of the rotating shaft A 10. The upper fork plate 8 and the driving rod 13 are relatively distributed on both sides of the rotating shaft A 10. A driving rotating shaft 12 is also provided at the end of the driving rod 13. A hydraulic cylinder 14 is provided under the driving rotating shaft 12. The hydraulic cylinder 14 and the driving rotating shaft 12 are connected by a connecting rod.

[0023] A rack 17 is further provided below the gear 15 . The rack 17 is fixed to the surface of the column 1 . Teeth are evenly distributed on the upper surface of the rack 17 . The gear 15 and the rack 17 are meshed with each other through the teeth.

[0024] A wind speed sensor 16 is also fixed to the upper end of one of the columns 1. The wind speed sensor 16 is used to detect the wind speed at the photovoltaic panel 5. Normally, the upper fork plate 8 and the lower fork plate 9 are in a stretched state on one side of the fixed plate 2, and the photovoltaic panel 5 is in a flat state. The photovoltaic panel 5 receives sunlight. When the wind speed sensor 16 detects that the wind speed value at the photovoltaic panel 5 is greater than the set value for a period of time, the hydraulic cylinder 14 starts to extend upward, driving the drive rod 13 to make a circular motion upward along the A rotation axis 10, and the upper fork plate 8 to make a circular motion downward along the A rotation axis 10. The lower fork plate 9 and the upper fork plate 8 are hinged at both ends to each other, causing the angle between the lower fork plate 9 and the upper fork plate 8 to gradually become smaller, that is, causing the lower fork plate 9 and the upper fork plate 8 to slide along the groove 3. The column 1 on one side of the hydraulic cylinder 14 gathers and moves, and the photovoltaic panel 5 also moves toward the column 1 on the side of the hydraulic cylinder 14. While the photovoltaic panel 5 moves, the gear 15 connected through the sliding column 4 also follows the photovoltaic panel 5 to move on the other side of the fixed plate 2. Since the gear 15 and the rack 17 are engaged with each other through the teeth, the gear 15 will also rotate while moving toward the column 1 on the side of the hydraulic cylinder 14, causing the photovoltaic panel 5 connected through the sliding column 4 to flip over. When the hydraulic cylinder 14 extends upward into position, the lower fork plate 9 and the upper fork plate 8 gather and fold into position, and the photovoltaic panel 5 flips into a vertical state. The photovoltaic panels 5 are gathered together to prevent the photovoltaic panel 5 from being damaged by the splash of sand and gravel due to excessive wind speed at the photovoltaic panel 5.

[0025] When the wind speed sensor 16 detects that the wind speed at the photovoltaic panel 5 is less than the set value for a period of time, the hydraulic cylinder 14 moves downward to reset, driving the drive rod 13 to make a circular motion downward along the A rotation axis 10, and the upper fork plate 8 to make a circular motion upward along the A rotation axis 10. The angle between the lower fork plate 9 and the upper fork plate 8 gradually increases, which prompts the lower fork plate 9 and the upper fork plate 8 to extend along the sliding groove 3 toward the column 1 on the side away from the hydraulic cylinder 14. The photovoltaic panel 5 also moves toward the column 1 on the side away from the hydraulic cylinder 14. The gear 15 and the rack 17 engage with each other through the teeth, and the photovoltaic panel 5 flips to a horizontal state to continue to receive sunlight.

[0026] The management and control structure includes a transmitting circuit, a stabilizing circuit and a telescoping circuit; like Figure 3 and Figure 4 As shown, the transmitting circuit includes module U1 and module U2. Module U1 is a wireless transmitting module, model LORA-MODBUS-4AO, and module U2 is an inverter module, model SUN-M160G4-EU-Q0. Pin 1 of module U2 is connected to the DC negative pole V-, and pin 2 of module U2 is connected to the source of MOS tube Q2. The drain of MOS tube Q2 is connected to the collector of transistor Q3, one end of resistor R8 and DC positive pole V+, and the other end of resistor R8 is connected to one end of resistor R9, The base of the transistor Q3 and the cathode of the Zener diode D1, the other end of the resistor R9 and the anode of the Zener diode D1 are connected to the ground wire. The emitter of the transistor Q3 is connected to one end of the resistor R10 and the gate of the MOS tube Q2. The other end of the resistor R10 is connected to the ground wire. Pin 3 of the module U2 is connected to the AC live wire L, and pin 4 of the module U2 is connected to the AC live wire N. An AC transformer U5 is also provided on the surface of the AC live wire L. The AC transformer U5 is an AC precision micro current transformer with model GL-CT226A.

[0027] The DC positive electrode V+ and the DC negative electrode V- come from the DC power generated by the photovoltaic panel, which is then input into the module U2 through the MOS tube Q2, inverted into AC power, and incorporated into the municipal power grid. The AC transformer U5 is used to measure the current in the AC live wire L and then convert it into a DC current signal. When the DC positive electrode V+ generated by the photovoltaic panel is greater than the set voltage value, the voltage value between the resistor R9 and the resistor R8 increases, and the voltage regulator diode D1 is turned on, so that the base voltage of the transistor Q2 is maintained at a constant value, preventing the DC voltage generated by the photovoltaic panel from suddenly increasing, causing the voltage at the AC output end of the module U2 to increase, thereby ensuring the voltage stability when the electricity generated by the photovoltaic panel is incorporated into the municipal power grid.

[0028] Pin 1 of the module U1 is connected to the power supply +3.3V, pins 2 and 6 of the module U1 are connected to the ground, pin 7 of the module U1 is connected to pin 1 of the AC transformer U5, pin 8 of the module U1 is connected to pin 2 of the AC transformer U5, pin 9 of the module U1 is connected to the positive wind speed signal FS+, pin 10 of the module U1 is connected to the negative wind speed signal FS-, pin 11 of the module U1 is connected to the ground, pin 12 of the module U1 is connected to one end of the inductor L1 and one end of the capacitor C2, the other end of the inductor L1 is connected to the antenna, and the other end of the capacitor C2 is connected to the ground.

[0029] like Figure 5 As shown, the stabilization circuit includes chip U3 and chip U4. Chip U3 and chip U4 are integrated operational amplifiers. The models of chip U3 and chip U4 are UA741. Pin 3 of chip U3 is connected to pin 5 of module U1 and one end of resistor R1, pin 2 of chip U3 is connected to one end of resistor R3, the other end of resistor R3 and pin 7 of chip U3 are connected to ground, pin 4 of chip U3 is connected to power supply +3.3V, pin 6 of chip U3 is connected to one end of resistor R4 and one end of capacitor C1, the other end of capacitor C1 is connected to ground, the other end of resistor R4 is connected to one end of resistor R5 and pin 3 of chip U4, and the other end of resistor R5 and pin 7 of chip U4 are connected to ground.

[0030] The other end of the resistor R1 is connected to pin 2 of the chip U4 and one end of the resistor R2, the other end of the resistor R2 is connected to pin 6 of the chip U4 and the base of the transistor Q1, pin 4 of the chip U4 is connected to the power supply +3.3V, the collector of the transistor Q1 is connected to the power supply +3.3V, the emitter of the transistor Q1 is connected to one end of the resistor R6, and the other end of the resistor R6 is connected to the ground wire.

[0031] The telescopic circuit includes chip U6, which is an optocoupler. The model of chip U6 is 817C. Pin 1 of chip U6 is connected to one end of resistor R7, and the other end of resistor R7 is connected to the emitter of transistor Q1. Pin 2 of chip U6 is connected to the ground wire, pin 3 of chip U6 is connected to the power supply +24V, and pin 4 of chip U6 is connected to the hydraulic cylinder power supply DC.

[0032] The wind speed sensor detects the real-time wind speed and inputs it through pins 9 and 10 of module U1. When module U1 receives a wind speed signal greater than the set value, pin 5 of module U1 outputs a certain DC current signal, which is input through pin 3 of chip U3 and then passes through the time integration circuit composed of chip U3 and chip U4. When the time integration circuit detects that the DC current signal output from pin 5 of module U1 reaches the set value for a certain time, that is, the wind speed signal is greater than the set value for a certain time, the time integration circuit composed of chip U3 and chip U4 is turned on, pin 6 of chip U4 outputs a high level, and then transistor Q1 is turned on, and the emitter current of transistor Q1 flows into the ground through resistor R6. At this time, resistor The current input terminal of R6, that is, the emitter terminal of transistor Q1, is at a high level, so the chip U6 connected to the emitter terminal of transistor Q1 through resistor R7 is turned on, the power supply terminal of the hydraulic cylinder is energized and extends upward, and the photovoltaic panels gather and fold to prevent the wind speed from being too high at a certain moment, which affects the misjudgment of the management and control structure. When the wind speed signal is less than the set value for a certain period of time, the time integration circuit composed of chip U3 and chip U4 is turned off, and pin 6 of chip U4 outputs a low level. The power supply terminal of the hydraulic cylinder is powered off and reset downward, and the photovoltaic panel is stretched and flat. Module U1 will also send the wind speed, inverter current and working status of the hydraulic cylinder at this part of the photovoltaic panel to the upper-level receiving terminal, so that the operator can grasp the working status of the photovoltaic panel in real time.
