[0046] Such as Figures 1-3An adjustable photovoltaic power generation device as shown. The adjustable photovoltaic power generation device includes a bracket 1, a panel frame 2, a photovoltaic panel 3, and a power mechanism 4. The bracket 1 is the overall load-bearing structure of the adjustable photovoltaic power generation device. The panel frame 2 is rotatably arranged on the bracket 1 and is used to mount and carry the photovoltaic panel 3. Specifically, the panel frame 2 is pivotally connected or hinged to the bracket 1 through a connecting shaft 5. Both ends of the connecting shaft 5 are connected to both sides of the bracket 1 respectively, and the panel frame 2 is rotatably sleeved on the connecting shaft 5, thus forming a rotatable connection between the panel frame 2 and the bracket 1. The photovoltaic panel 3 is arranged on the panel frame 2 and is used for generating electric energy from light energy. The power mechanism 4 is an electric push rod, and the electric push rod is connected to the panel frame 2 to drive the panel frame 2 to rotate. For the photovoltaic power generation device, in the case of being equipped with an energy storage device, the corresponding reserve energy is electric energy. In the utility model, electric energy is used as the energy of the power mechanism 4, and the energy supply is convenient. After the electric energy is supplied, the electric push rod can make telescopic movements, thereby driving the panel frame 2 to rotate in two opposite directions. Specifically, it drives the panel frame 2 to rotate in three angular states as shown in Figure 3 、 Figure 5 、 Figure 6 . Especially, during the process of photovoltaic power generation, the electric push rod can be used to push the panel frame 2 and the photovoltaic panel 3 on the panel frame 2 to rotate with the rising and setting of the sun, so as to adjust the area of the photovoltaic panel 3 facing the sunlight and improve the photovoltaic power generation efficiency.

[0047] In some embodiments of the electric push rod, as shown in Figure 7 、 Figure 8 , the electric push rod includes a long cylindrical housing 41, a motor 42, a lead screw 43, a driving slider 44, and an output rod 45. The long cylindrical housing 41 has a cylindrical cavity inside. The lead screw 43 is arranged inside the long cylindrical housing 41. The driving slider 44 is slidably arranged inside the long cylindrical housing 41. The driving slider 44 is in threaded cooperation with the lead screw 43. The motor 42 is connected to the lead screw 43. The inner end of the output rod 45 extends into the long cylindrical housing 41, and the inner end of the output rod 45 is connected to the driving slider 44. The outer end of the output rod 45 is connected to the panel frame 2. In this embodiment, the motor 42 drives the lead screw 43 to rotate. The driving slider 44 can only move along the axial direction of the long cylindrical housing 41 under the guidance of the long cylindrical housing 41. Driven by the lead screw 43, the driving slider 44 slides inside the long cylindrical housing 41 as the lead screw 43 rotates. The driving slider 44 drives the output rod 45 to make telescopic movements, so that the panel frame 2 can be adjusted through the output rod 45.

[0048] Moreover, the driving slider 44 is driven to rise and fall by the transmission mode of the motor 42 and the lead screw 43. Since the lead screw 43 has good self-locking performance, the electric push rod can be used as a support structure to bear pressure for a long time. The self-locking performance also enables the electric push rod not to contract and extend under external forces and can accurately control the elongation and contraction accuracy.

[0049] Furthermore, for the slidable implementation mode of the driving slider 44, specifically, as shown in Figure 8As described above, after partial sectioning of the long cylindrical housing 41 in the figure, an opening is cut out on the side of the long cylindrical housing 41, so that it can be seen that a guide rail 46 is provided inside the long cylindrical housing 41, and the guide rail 46 extends along the axial direction of the long cylindrical housing 41. A groove 441 is provided on the driving slider 44, and the driving slider 44 is slidably engaged with the guide rail 46 through the groove 441.

[0050] Specifically, one, two, three or more other numbers of guide rails 46 can be provided. A plurality of rows of fastening holes are provided on the surface of the long cylindrical housing 41, and each row of fastening holes extends along the axial direction. A threaded hole is provided on the side of the corresponding guide rail 46 close to the inside, and the guide rail 46 can be locked and fixed by passing a locking screw through the locking hole and extending it into the threaded hole.

[0051] In some embodiments of the output rod 45, such as Figure 8 shown, a connecting flange 451 is provided at the inner end of the output rod 45, and the connecting flange 451 is connected to the driving slider 44. The output rod 45 is locked to the driving slider 44 through the connecting flange 451, and the output rod 45 can move synchronously with the driving slider 44.

[0052] In addition, as Figure 8 shown, an upper hinge joint 452 is further provided at the outer end of the output rod 45, and the upper hinge joint 452 connects to the plate frame 2. Correspondingly, a lower hinge joint 421 is further provided at the lower end of the motor 42. The upper hinge joint 452 is hinged to the plate frame 2, and the lower hinge joint 421 is hinged to the bracket 1.

[0053] In some embodiments of the electric push rod, such as Figure 8 shown, the electric push rod further includes an upper end cover 47 and a lower end cover 48. The upper end cover 47 is arranged at the upper end of the long cylindrical housing 41, and an upper through hole for the output rod 45 to pass through is provided on the upper end cover 47. The lower end cover 48 is arranged at the lower end of the long cylindrical housing 41, and a lower through hole for the motor 42 to pass through is provided on the lower end cover 48. The upper end opening of the long cylindrical housing 41 is sealed by the upper end cover 47, and the lower end opening is blocked by the lower end cover 48.

[0054] In some embodiments of the lead screw 43 and some output rods 45, such as Figure 8 shown, the output rod 45 is partially sectioned in the figure, and through this figure, it can be seen that a sliding hole 453 is provided inside the output rod 45, a slider 431 is provided at the top end of the lead screw 43, and the upper end of the lead screw 43 extends into the sliding hole 453 of the output rod 45, and at the same time, the slider 431 is slidably engaged with the sliding hole 453.

[0055] In some embodiments of the adjustable photovoltaic power generation device, the adjustable photovoltaic power generation device further includes a control device and an angle sensing component 6. Such as Figure 3 、 Figure 4As shown in the figure, a part of the angle sensing component 6 is arranged on the bracket 1, and another part of the angle sensing component 6 is arranged on the plate rack 2. The control device is electrically connected to the angle sensing component 6, and the control device is also electrically connected to the motor 42. The control device controls the start, stop, forward rotation or reverse rotation of the motor 42. During the process of photovoltaic power generation, the electric push rod is used to push the plate rack 2 and the photovoltaic panel 3 on the plate rack 2 to rotate with the rising and setting of the sun. The angle sensing component 6 can sense the angle of the plate rack 2 and feedback the adjustment result in real time, so as to improve the accuracy of angle adjustment.

[0056] Specifically, the control device can be a single-chip microcomputer, a computer, an industrial control computer, a main board or a processor, etc.

[0057] In some embodiments of the angle sensing component 6, such as Figure 4 As shown in the figure, the angle sensing component 6 includes an angle disk 61 and a scale sensor 62. The angle disk 61 is fixedly connected to the plate rack 2, and the angle disk 61 is also provided with scales. The scale sensor 62 is arranged on the bracket 1 and close to the side of the angle disk 61 with scales. The angle disk 61 is provided with protruding structures radially distributed along the circumferential direction, and the protruding structures are evenly distributed, thus forming the scales of the angle. The scale sensor 62 is a sensor for emitting and receiving electromagnetic signals. When the electromagnetic signal sweeps across the scale, fluctuations in the reflection of the electromagnetic signal will be generated, so as to sense the amplitude of angle adjustment and calculate the cumulative adjustment amount.

[0058] Furthermore, the angle adjustment is a long-term adjustment, and errors are likely to accumulate during the actual adjustment process. Therefore, as Figure 4 As shown in the figure, the angle sensing component 6 further includes an induction sheet 63, an intermediate position sensor 64 and two extreme position sensors 65. The induction sheet 63 is arranged at the edge of the angle disk 61. The intermediate position sensor 64 is arranged on the bracket 1 to locate the intermediate position or horizontal position of the plate rack 2. The intermediate position sensor 64 is close to the movement track of the induction sheet 63. When the induction sheet 63 passes through the intermediate position sensor 64, the intermediate position sensor 64 is triggered to generate an induction. The two extreme position sensors 65 are arranged on both sides of the bracket 1 to locate the flipping extreme positions of the plate rack 2. The intermediate position sensor 64 is the intermediate position of the rotation range of the plate rack 2. When the plate rack 2 is in a horizontal state as a whole, the intermediate position is also the horizontal position. The intermediate position and the extreme positions are fixed positions on the bracket 1, and the induction can only be triggered when the plate rack 2 rotates to the fixed position. By setting the intermediate position sensor 64, the rotation deviation of the plate rack 2 can be calibrated, and the rotation limit and rotation deviation can be calibrated by the extreme position sensors 65.

[0059] Further, the middle position sensor 64 is a photoelectric sensor. The sensing piece 63 rotates with the plate frame 2. When the sensing piece 63 passes the middle position sensor 64, the sensing piece 63 blocks the light of the middle position sensor 64, thereby generating a light change and different photoelectric effects, thus triggering the sensing. The limit sensor is specifically a pressure switch or a photoelectric sensor, etc.

[0060] In addition, to improve the installation convenience of the foregoing sensors, as Figures 4 to 7 shown, the bracket 1 of this embodiment is further provided with a sensor mounting plate 7. The sensor mounting plate 7 is arranged on the bracket 1 and is located on the side of the angle scale 61 with scale. During installation, first set the middle position sensor 64 and the scale sensor 62 on the sensor mounting plate 7, and then install the sensor mounting plate 7 on the bracket 1, so that each sensor can be disassembled and assembled uniformly, improving the disassembly and assembly speed and convenience.

[0061] In the specific structure of some brackets 1, the bracket 1 includes two triangular brackets arranged side by side and a connecting rod arranged between the two triangular brackets. The two ends of each connecting rod are respectively connected to the two triangular brackets.

[0062] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
