It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0020] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 The present invention provides a retractable solar power generation device, including an articulated mounting frame 17, a support and adjustment device 7, a protection box 1 and a control base 5; the support and adjustment device 7 is arranged at the bottom of the articulated mounting frame 17, the protection box 1 is arranged below the support and adjustment device 7, and the control base 5 is arranged below the protection box 1.

[0021] Among them, at least two solar power generation modules 6 are arranged on the articulated mounting frame 17 from top to bottom, the support and adjustment device 7 includes a lifting frame 703, and the top of the lifting frame 703 is hingedly mounted with the articulated mounting frame 17 through an articulated seat 702, and a first push rod 701 is hingedly mounted on the lifting frame 703, and the output end of the first push rod 701 is hingedly mounted with the rear end of the articulated mounting frame 17 and is used to adjust the inclination angle of the articulated mounting frame 17. The lifting height of the lifting frame 703 is adjusted by a pair of symmetrically arranged lifting devices 9 in the protection box 1, and the anemometer 13 and the sun tracker 14 are fixedly installed on the outside of the protection box 1. The inclination angle of the articulated mounting frame 17 relative to the ground can be adjusted by the first push rod 701, so that the sunlight at different heights can be vertically irradiated to the solar power generation module 6, and the lifting device 9 can lift the articulated mounting frame 17 and the support and adjustment device 7 from the protection box 1 or retract it into the protection box 1 as needed. Specifically, when there is strong wind, in order to prevent the solar power generation module 6 from being damaged by the strong wind, the solar power generation module 6 can be retracted into the protective box 1 for protection through the lifting device 9; and when the external strong wind disappears, the solar power generation module 6 can be lifted to a suitable position again through the lifting device 9 to generate electricity.

[0022] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig. 9The control base 5 includes a sealed shell 503 fixed on the ground, and an energy storage device 501, a main motor 502 and a controller 504 are fixedly installed in the sealed shell 503. The energy storage device 501 is electrically connected to the solar power generation module 6 and the controller 504 respectively, and the controller 504 is electrically connected to the first push rod 701, the anemometer 13, the solar tracker 14 and the main motor 502 respectively. The output end of the main motor 502 is fixedly installed at the bottom of the protection box 1 and is used to drive the protection box 1 to rotate. The wind speed in the environment can be measured by the anemometer 13, so that the solar power generation module 6 can be sent into the protection box 1 for protection in strong wind weather. The energy storage device 501 can be a lithium battery pack or a storage battery pack, and the controller 504 can be a PLC controller. The main motor 502 can be a stepper motor. At the same time, in order to better utilize the electric energy generated by the solar power generation module 6, the solar power generation module 6 can also be directly connected to the power grid through a photovoltaic inverter. The solar tracker 14 is used to locate the position of the sun, thereby using the main motor 502 to adjust the direction of the solar power generation module 6, and then adjusting the inclination angle of the solar power generation module 6 through the first push rod 701, so as to ensure that the sunlight can always be received by the solar power generation module 6 in a vertical manner, thereby improving the efficiency of power generation.

[0023] See also Figure 3 The lifting device 9 includes a lifting and adjusting motor 904 fixedly installed inside the protection box 1, and the output end of the lifting and adjusting motor 904 drives a second driving wheel 902, a first moving seat 705 is fixedly installed at the bottom of the lifting frame 703, and a main screw rod 901 for driving the first moving seat 705 to perform lifting and lowering movement is rotatably installed in the protection box 1, and a second driven wheel 903 is fixedly installed at the bottom of the main screw rod 901, the second driving wheel 902 and the second driven wheel 903 are meshed and connected, and the lifting and adjusting motor 904 is electrically connected to the controller 504. The lifting and adjusting motor 904 can drive the second driving wheel 902 to rotate, and then use the second driving wheel 902 to drive the second driven wheel 903 to rotate, so that the main screw rod 901 coaxially installed with the second driven wheel 903 can rotate, and the simultaneous rotation of the two main screw rods 901 can drive the lifting frame 703 to lift and lower, thereby controlling the lifting and lowering of the solar power generation module 6.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4A pair of second screw motors 18 are fixedly mounted on the protection box 1, and the output ends of the two second screw motors 18 are respectively driven by screws to have a limit sealing plate 19, and an elastic sealing film 20 for sealing the top of the protection box 1 is arranged between the limit sealing plate 19 and the top of the protection box 1, and the front and rear sides of the lifting frame 703 are provided with limit matching grooves 704 that are clamped and sealed with the limit sealing plate 19, and the second screw motor 18 is electrically connected to the controller 504. The cooperation between the limit sealing plate 19 and the elastic sealing film 20 can be used to prevent dust in the air from entering the protection box 1, and can also provide additional support for the lifting frame 703. Specifically, when the articulated mounting frame 17 is completely stored in the protection box 1 by the lifting device 9, the two limiting sealing plates 19 can be tightly fitted together on the top of the protection box 1 through the driving of the two second screw motors 18. At this time, the two limiting sealing plates 19 can be used in conjunction with the elastic sealing film 20 to completely seal the top of the protection box 1. When the articulated mounting frame 17 is pushed out of the protection box 1 by the lifting device 9 and the lifting frame 703 is moved to a specified height, the two second screw motors 18 can drive the two limiting sealing plates 19 to be clamped into the limiting matching grooves 704 on the front and rear sides of the lifting frame 703, thereby effectively utilizing the limiting sealing plates 19 to clamp and support the lifting frame 703, thereby improving the structural strength of the lifting frame 703 and the articulated mounting frame 17, and preventing the solar power generation module 6 from shaking in the wind. At this time, the top of the protection box 1 will be sealed by the lifting frame 703, the limiting sealing plates 19 and the elastic sealing film 20, which can effectively prevent dust from entering the interior of the protection box 1.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Fig.10 , Fig.11 , Fig.12 and Fig.13The solar power generation module 6 is installed on the articulated mounting frame 17 through the fixing device 3, and the solar power generation module 6 includes a solar cell panel 601, and the solar cell panel 601 is provided with a limit hole 602 and a limit connection groove 604, the fixing device 3 includes a connecting shell 302 rotatably installed on the articulated mounting frame 17 through a rotating shaft, and the end of the rotating shaft is coaxially installed with a first driven wheel 301, a second rack 15 meshing with the first driven wheel 301 is slidably installed on the articulated mounting frame 17, and a second push rod 16 for driving the second rack 15 to move and thereby drive the first driven wheel 301 to rotate is fixedly installed on the articulated mounting frame 17, a connecting plate 307 is integrally formed on the connecting shell 302, and a connecting plate 307 is fixedly installed with a limit hole 6 inserted into the limit hole 6 along the front and rear directions. 02, a limiting column 306 for limiting the solar panel 601 is slidably installed in the connecting shell 302, and an insertion block 303 is inserted into the limiting connecting groove 604 along the left and right directions to limit the solar panel 601, and a fastening operation device 2 for driving the insertion block 303 to move is provided in the connecting plate 307, the second push rod 16 is electrically connected to the controller 504, and the left and right ends of the articulated mounting frame 17 are fixed with a protective shell 21 by bolts, and the protective shell 21 and the articulated mounting frame 17 are jointly formed with a mounting cavity 22 for accommodating and closing the second rack 15 and the first driven wheel 301, and the protective shell 21 can prevent external dust from interfering with the normal meshing between the second rack 15 and the first driven wheel 301, thereby improving the service life of the equipment.

[0026] When the solar power generation module 6 needs to be installed, the solar panel 601 is first attached to the connecting shell 302 from the front end of the connecting shell 302, so that the limiting column 306 can be inserted into the limiting hole 602, and then the insertion block 303 is driven by the fastening operation device 2 to be inserted into the limiting connection groove 604, so that the solar power generation module 6 and the connecting shell 302 can be fixed, and then the solar power generation module 6 can be driven to rotate by the second push rod 16, so as to facilitate the adjustment of the solar panel 601 to a position perpendicular to the sunlight, thereby improving work efficiency. Both the first push rod 701 and the second push rod 16 can use electric push rods. In addition, the use of the second push rod 16 to adjust the inclination angle of the solar power generation module 6 can also help to resist strong wind weather. Specifically, by adjusting the inclination angle of the articulated mounting frame 17 by the first push rod 701 and adjusting the inclination angle of the solar power generation module 6 by the second push rod 16, the solar panel 601 can still form an angle with the articulated mounting frame 17 while maintaining verticality with the sunlight, thereby forming a gap between each solar power generation module 6 and the articulated mounting frame 17 for convenient airflow, thereby reducing the area pushed by wind and effectively reducing wind interference.

[0027] The retractable solar power generation device designed in this embodiment can effectively use the first push rod 701 and the second push rod 16 to assist the solar panel 601 to rotate to a position perpendicular to the sunlight to improve work efficiency. At the same time, the solar power generation module 6 can be stored in the protective box 1 through the lifting device 9 in strong wind weather to reduce damage. Moreover, since the articulated mounting frame 17 can be stored, it only needs to occupy less horizontal space on the ground after storage, so it is not necessary to reserve additional space for maintenance during installation. At the same time, by increasing the vertical height of the articulated mounting frame 17 and the number of solar power generation modules 6, a larger area for receiving sunlight can be obtained without the need to reserve enough horizontal space for storage, so that multiple devices can be arranged in an array more densely, so as to make full use of sunlight. It solves the problems of large footprint, low resistance to strong winds, low power generation efficiency, and inconvenient installation of existing solar power generation equipment, and can effectively enhance the protection and power generation efficiency of the equipment.

[0028] Example 2: Please refer to Figure 1 , Figure 3 and Figure 8 On the basis of the first embodiment, a flushing device 8 is provided in the protection box 1, and the flushing device 8 includes a guide rail 802 fixedly installed inside the protection box 1, and a first screw motor 801 is fixedly installed at the end of the guide rail 802, and the output end of the first screw motor 801 is driven by a screw to have a second movable seat 804 sliding along the guide rail 802, and a nozzle 803 for spraying water to the surface of the solar power generation module 6 is fixedly installed on the second movable seat 804, the nozzle 803 is connected to an external water supply device through an inlet pipe 805, and the inlet pipe 805 is connected to a solenoid valve 11 for controlling the water flow rate in the inlet pipe 805, and a drain pipe 12 for discharging waste water inside the protection box 1 is provided at the bottom of the protection box 1, and the solenoid valve 11 is electrically connected to the controller 504.

[0029] In this embodiment, the flushing device 8 can be used to flush the surface of the solar panel 601, so as to clean the dust on the surface of the solar panel 601, so that the sunlight can be effectively received by the solar panel 601 normally, thereby ensuring the working efficiency of the solar panel 601. When the solar panel 601 needs to be flushed, the articulated mounting frame 17 is first completely stored in the protection box 1, and the two limit sealing plates 19 are adjusted to the non-working position, so that the top of the protection box 1 can be completely exposed, and then the articulated mounting frame 17 is lifted to the outside of the protection box 1 at a specified speed by the lifting device 9. At this time, the solenoid valve 11 is opened, and at the same time, under the push of the first screw motor 801, the second movable seat 804 will move back and forth along the guide rail 802, so that the water flow sprayed by the nozzle 803 can repeatedly flush the surface of each solar power generation module 6 in turn, so that the surface of each solar power generation module 6 can be cleaned. It further solves the problems of existing solar power generation equipment such as large footprint, low resistance to strong winds, low power generation efficiency, and inconvenient installation, and can effectively enhance the protection and power generation efficiency of the equipment.

[0030] Example 3: Please refer to Fig.11 , Fig.12 and Fig.13 On the basis of the second embodiment, the fastening operation device 2 includes an operating rod 201 screwed on the connecting shell 302, and the bottom of the operating rod 201 is coaxially fixedly installed with a non-circular insertion rod 202, the interior of the connecting shell 302 is rotatably installed with a rotating docking seat 203, and the rotating docking seat 203 is coaxially plugged and installed with the non-circular insertion rod 202, the end of the rotating docking seat 203 is coaxially installed with a first driving wheel 204, and the insertion block 303 is fixedly installed with a first rack 304 meshingly connected with the first driving wheel 204. When the operating rod 201 is rotated, the operating rod 201 is screwed with the connecting shell 302, so the operating rod 201 will drive the non-circular insertion rod 202 to slide along the central axis of the rotating docking seat 203. At the same time, since the cross section of the non-circular insertion rod 202 is non-circular, the non-circular insertion rod 202 can also drive the rotating docking seat 203 to rotate together, so that the rotating docking seat 203 can drive the first driving wheel 204 to rotate, and the rotation of the first driving wheel 204 can drive the first rack 304 to move, so that the first rack 304 is used to push the insertion block 303 to be inserted into the limiting connection groove 604 or pulled out from the limiting connection groove 604, so that the assembly and disassembly process between the fixing device 3 and the solar power generation module 6 can be controlled by the fastening operating device 2. It further solves the problems of large footprint, low resistance to strong winds, low power generation efficiency, and inconvenient installation of existing solar power generation equipment, and can effectively enhance the protection and power generation efficiency of the equipment.

[0031] Example 4: Please refer to Figure 6 , Fig.11 and Fig.12 On the basis of the third embodiment, an arc-shaped matching groove 23 coaxially arranged with the first driven wheel 301 is provided on the articulated mounting frame 17, and a limiting device 4 inserted into the arc-shaped matching groove 23 and sliding along the arc-shaped matching groove 23 is fixedly installed on the connecting shell 302, and the limiting device 4 includes a sliding column 403 fixedly installed with the connecting shell 302, and a limiting groove 401 is provided in the sliding column 403, a ball head rod 406 is slidably installed in the limiting groove 401, and the non-ball head end of the ball head rod 406 is connected to the bottom of the limiting groove 401 through a reset spring 402, the ball head end of the ball head rod 406 is clamped and installed with the arc-shaped clamping groove set in the arc-shaped matching groove 23, an annular limiting groove 405 is provided on the ball head rod 406, and a limiting ring 404 is provided inside the limiting groove 401, which is sleeved with the annular limiting groove 405 and is used to limit the movement position of the ball head rod 406.

[0032] In this embodiment, when the fixing device 3 is driven to rotate by the second push rod 16, the ball end of the ball head rod 406 will be subjected to a thrust exceeding the preset value and will slide out of the arc-shaped slot in the arc-shaped matching slot 23 until it follows the rotation of the fixing device 3 to a new position in the arc-shaped matching slot 23. At this time, the ball head of the ball head rod 406 will enter the arc-shaped slot at the new position under the push of the reset spring 402, so that the ball head rod 406 is used to further fix the connection shell 302 and the articulated mounting frame 17, thereby avoiding the shaking of the solar power generation module 6 under the action of wind, so as to reduce the wear of the equipment during use and improve the service life of the equipment. It further solves the problems of large footprint, low resistance to strong winds, low power generation efficiency, and inconvenient installation of existing solar power generation equipment, and can effectively enhance the protection and power generation efficiency of the equipment.

The first terminal block 305 and the second terminal block 603 are plugged and fixed and electrically connected. Through this connection method, there is no need to additionally connect the solar panel 601 and the energy storage device 501. When the solar power generation module 6 is normally connected to the fixing device 3, the solar power generation module 6 can be electrically connected to the energy storage device 501 through the correct plugging between the first terminal block 305 and the second terminal block 603. When the solar power generation module 6 is separated from the fixing device 3, the electrical connection between the solar panel 601 and the energy storage device 501 can also be disconnected, thereby realizing the rapid disassembly and assembly of the solar power generation module 6 and facilitating maintenance. A threading tube 10 is fixedly installed on the lifting frame 703, and the cable on the first wiring seat 305 for electrically connecting the energy storage device 501 is inserted into the protection box 1 through the threading tube 10, and the cable on the first push rod 701 and the second push rod 16 for electrically connecting the controller 504 is inserted into the protection box 1 through the threading tube 10. The corresponding cables are inserted into the protection box 1 through the threading tube 10, and then the corresponding cables are connected to the energy storage device 501 or the controller 504 through the bottom of the protection box 1. In this way, the corresponding cables can be effectively prevented from passing through the side of the protection box 1 and colliding with external objects and breaking, thereby improving the reliability of the equipment operation. It further solves the problems of large footprint, low resistance to strong winds, low power generation efficiency, and inconvenient installation of existing solar power generation equipment, and can effectively enhance the protection and power generation efficiency of the equipment.

[0034] Embodiment 6: Based on Embodiment 5, the present invention further provides a method for using a retractable solar power generation device, comprising the following steps: Step 1: First, fix the control base 5 to the ground, then fix the protection box 1 to the output end of the main motor 502, then correctly install the support adjustment device 7 and the articulated mounting frame 17, and then correctly fix each solar power generation module 6 to the corresponding position of the articulated mounting frame 17 through the corresponding fixing device 3; Step 2: When the device is performing normal power generation operation, the controller 504 will obtain the position of the sun in real time through the solar tracker 14, and then adjust the position of the solar panel 601 through the first push rod 701 and the second push rod 16, so that the sunlight can be irradiated vertically on the solar panel 601, so that the solar panel 601 can have the most efficient power generation efficiency. At the same time, the controller 504 will also detect the wind force in the environment through the anemometer 13, so that in strong wind weather, the articulated mounting frame 17 can be retracted into the protection box 1 for protection through the lifting device 9, and the top of the protection box 1 is sealed by the limiting sealing plate 19 and the elastic sealing film 20, so that the solar power generation module 6 can be effectively prevented from being damaged, thereby increasing the service life of the device; Step three: When the solar panel 601 needs to be rinsed, first completely store the articulated mounting frame 17 into the protective box 1, and adjust the two limit sealing plates 19 to the non-working position so that the top of the protective box 1 can be completely exposed, and then use the lifting device 9 to lift the articulated mounting frame 17 to the outside of the protective box 1 at a specified speed. At this time, the solenoid valve 11 is opened, and at the same time, under the push of the first screw motor 801, the second movable seat 804 will move back and forth along the guide rail 802, so that the water flow sprayed by the nozzle 803 can repeatedly flush the surface of each solar power generation module 6 in turn, so that the surface of each solar power generation module 6 can be cleaned.
