[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly to an adjustable distributed photovoltaic power generation device and a using method thereof. Background Technique

[0002] Photovoltaic technology is a technology that converts solar energy into electrical energy. A distributed photovoltaic power generation device is generally a type of photovoltaic power generation. By using a support structure to install photovoltaic panels in a distributed manner, it can receive solar energy to the greatest extent for photovoltaic power generation and is applied to various photovoltaic power generation production occasions.

[0003] At present, on cloudy days, rainy days or when the solar radiation intensity fluctuates, it will have a significant impact on the power generation effect and power quality of the photovoltaic panels. Therefore, when arranging and installing a photovoltaic power generation device on site, it is necessary to adjust the position of the photovoltaic panels according to the requirements of the region or terrain. When adjusting the photovoltaic panels, the adjusting support structure usually makes hard contact with the photovoltaic panels, resulting in poor seismic resistance and being extremely easy to cause damage and deformation when the photovoltaic panels are affected by external forces; during the long-term use of the photovoltaic panels, dust and impurities will inevitably adhere to their surfaces, which will affect the absorption of light energy and regular cleaning work is required. However, the laying range of photovoltaic power generation is wide and the area is large, which brings inconvenience to the cleaning work, and it is easy to have cleaning dead corners. Moreover, some impurities will adhere to the photovoltaic panels, further increasing the cleaning difficulty. Summary of the Invention

[0008] As a further solution of the present invention, sliding cylinders are respectively rotatably connected to both sides of the top of the support plate through pin shafts. A sliding rod is slidably connected inside the sliding cylinder. The top end of the sliding rod is rotatably connected to the upper side of one side of the adjusting plate through a pin shaft.

[0009] As a further solution of the present invention, the driving component includes a motor. The motor is fixed to the top of the inner wall of the groove. A lead screw is fixed on the output shaft of the motor.

[0011] As a further solution of the present invention, a sliding hole is provided on one side of the inner wall of the groove.

The gear is meshed and connected with the gear. The gear ring is clamped outside the hollow shaft. The gear is meshed with the teeth inside the groove.

[0012] As a further solution of the present invention, a water pump is connected to the bottom end of the water guide pipe. The water pump is fixed on one side of the support frame. A baffle is provided above the hollow shaft and the cleaning brush. The baffle is designed in an L shape and is fixed on the top of the support frame.

[0013] A usage method of an adjustable distributed photovoltaic power generation device, the usage method includes the following steps:

[0014] When adjusting the photovoltaic power generation device, control the multi-stage electro-hydraulic rod to extend so that it drives the support plate to move upward. The support plate is limited by two slideways to improve the stability of the vertical movement of the support plate. During the upward movement of the support plate, multiple sliding cylinders will be pushed by the pin shaft. When the sliding cylinder drives the sliding rod to move, the bottom end of the sliding cylinder rotates on the top of the support plate through the pin shaft, and the top end of the sliding rod rotates above one side of the adjusting plate through the pin shaft. When the adjusting plate is pressed, the top of the adjusting plate drives the rotating shaft to rotate inside the support frame, that is, the adjusting plate drives the photovoltaic panel to adjust the angle, so that the photovoltaic panel receives solar energy to the greatest extent for photovoltaic power generation;

[0015] When the adjusting plate or the photovoltaic panel is affected by an external force due to the fall of a heavy object, the adjusting plate squeezes the sliding rod through the pin shaft, and the sliding rod slides inside the sliding cylinder. At the same time, the guide rod at the bottom end of the sliding rod slides in the chute inside the sliding cylinder, playing a role in limiting the sliding rod and improving the stability of the sliding rod's support for the adjusting plate. And during the movement of the sliding rod, the spring is squeezed, and the elastic force of the spring supports the sliding rod, providing an upward force to the sliding rod and supporting the adjusting plate, playing a role in supporting and buffering the photovoltaic panel inside the adjusting plate, preventing the photovoltaic panel from being severely damaged and deformed due to external forces, and thus improving the anti-seismic protection effect on the photovoltaic panel;

[0016] When cleaning the surface of the photovoltaic panel, control the multi-stage electric hydraulic rod to contract and pull the pallet downward. The pallet then pulls the adjusting plate to deflect through the sliding cylinder and the sliding rod, so that the bottoms of the two adjusting plates approach each other until they contact the side plate on one side of the multi-stage electric hydraulic rod. The side plate supports and limits the adjusting plate, keeping the adjusting plate and the photovoltaic panel always in a vertical state, which is conducive to the falling of dust and impurities. Control the motor to work and drive the screw rod to rotate. During the rotation of the screw rod inside the nut, the nut will drive the sliding seat on one side to slide inside the groove. The two sliding seats are sleeved with the two ends of the hollow shaft through the shaft sleeve, so that the two sliding seats will drive the hollow shaft to move downward. During the downward movement of the sliding seat, the gear is driven to move. When the gear meshes with the tooth teeth, the gear will rotate counterclockwise. The gear drives the hollow shaft to rotate clockwise through the tooth ring, so that the hollow shaft drives the external cleaning brush to rotate clockwise and contact the photovoltaic panel inside the adjusting plate during the downward movement, achieving the purpose of scraping the photovoltaic panel. During the downward movement of the hollow shaft driving the cleaning brush, the cleaning brush rotates clockwise, so as to increase the friction between the cleaning brush and the photovoltaic panel, and the cleaning brush scrapes the photovoltaic panel from top to bottom, improving the scraping effect;

[0017] At the same time, control the water pump to work. The water pump pumps water from the water source and conducts the water into the water guide pipe. The water guide pipe conducts the water into the hollow shaft through the rotary joint. The hollow shaft is connected to the water guide pipe through the rotary joint. The normal conduction work between the water guide pipe and the inside of the hollow shaft will not be affected while the hollow shaft rotates, ensuring that the water inside the hollow shaft continuously sprays out from the external water outlet holes. The water sprayed out from the water outlet holes will wet the cleaning brush, improving the scrubbing ability of the cleaning brush. At the same time, the water sprayed out from the water outlet holes will soften the dust and impurities attached to the surface of the photovoltaic panel. Cooperating with the continuous rotation of the cleaning brush, and the lengths of the hollow shaft and the cleaning brush are greater than the width of the photovoltaic panel. During the up and down movement of the hollow shaft, the cleaning brush will fully cover the surface of the photovoltaic panel, further improving the cleaning effect and cleaning efficiency of the photovoltaic panel. Moreover, the photovoltaic panel is in a vertical state at this time, and the dirt generated by the cleaning will flow down along the photovoltaic panel, preventing the dirt from adhering to the photovoltaic panel and causing secondary pollution to it. When the hollow shaft drives the cleaning brush to move below the adjusting plate, control the motor to work in the reverse direction. Similarly, the sliding seat will drive the hollow shaft and the cleaning brush to move upward and be located above the adjusting plate, so that the hollow shaft and the cleaning brush are located inside the baffle with an L-shaped design, protecting the hollow shaft and the cleaning brush when no cleaning work is carried out, and at the same time not affecting the normal adjustment work of the adjusting plate and the photovoltaic panel.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In the present invention, two sliding seats drive the hollow shaft to move downward. During the downward movement of the sliding seats, the gears are driven to move. When the gears mesh with the teeth, the gears rotate counterclockwise. The gears drive the hollow shaft to rotate clockwise through the toothed ring, so that the hollow shaft drives the external cleaning brush to rotate clockwise and contact the photovoltaic panel in the adjusting plate during the downward movement, achieving the purpose of scraping the photovoltaic panel. During the downward movement of the hollow shaft driving the cleaning brush, the cleaning brush rotates clockwise, thereby increasing the friction between the cleaning brush and the photovoltaic panel, enabling the cleaning brush to scrape the photovoltaic panel from top to bottom and improving the scraping effect. The water pump pumps water from the water source and conducts the water into the water conduit. The water conduit conducts the water into the hollow shaft through the rotary joint. The water sprayed out from the water outlet holes wets the cleaning brush, improving the scrubbing ability of the cleaning brush. At the same time, the water sprayed out from the water outlet holes softens the dust and impurities attached to the surface of the photovoltaic panel. Cooperating with the continuous rotation of the cleaning brush, and the lengths of the hollow shaft and the cleaning brush are greater than the width of the photovoltaic panel. During the up and down movement of the hollow shaft, the cleaning brush will fully cover the surface of the photovoltaic panel, without cleaning dead corners. Moreover, the photovoltaic panel is in a vertical state at this time, and the dirt generated during cleaning will flow down along the photovoltaic panel, preventing the dirt from adhering to the photovoltaic panel and causing secondary pollution, further improving the cleaning effect and cleaning efficiency of the photovoltaic panel.

[0020] 2. In the present invention, the support plate moves upward and presses multiple sliding cylinders. During the process of the sliding cylinders driving the sliding rods to move, the bottom ends of the sliding cylinders rotate on the top of the support plate through the pin shafts, and the top ends of the sliding rods rotate above one side of the adjusting plate through the pin shafts. When the adjusting plate is pressed, the top of the adjusting plate drives the rotating shaft to rotate inside the support frame, that is, the adjusting plate drives the photovoltaic panel to adjust the angle, enabling the photovoltaic panel to receive solar energy to the greatest extent for photovoltaic power generation. When the adjusting plate or the photovoltaic panel is affected by an external force due to the fall of a heavy object, the adjusting plate presses the sliding rod through the pin shaft, and the sliding rod slides inside the sliding cylinder. At the same time, the guide rod at the bottom end of the sliding rod slides in the chute inside the sliding cylinder, playing a role in limiting the sliding rod, improving the stability of the sliding rod in supporting the adjusting plate, and squeezing the spring during the movement of the sliding rod. The elastic force of the spring supports the sliding rod, providing an upward force to the sliding rod and supporting the adjusting plate, playing a role in supporting and buffering the photovoltaic panel inside the adjusting plate, preventing the photovoltaic panel from being severely damaged and deformed under the action of external forces, and thus improving the anti-seismic protection effect on the photovoltaic panel.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0034] Please refer to Figures 1 - 9 , the present invention provides a technical solution:

[0035] An adjustable distributed photovoltaic power generation device includes a support frame 1. A base 2 is fixedly connected to the bottom of the support frame 1. Rotating shafts 5 are rotatably installed on both sides inside the support frame 1 through bushings. An adjusting plate 3 is clamped outside the rotating shafts 5. A photovoltaic panel 4 is fixedly installed inside the adjusting plate 3. An adjusting component 6 is fixedly installed at the bottom inside the support frame 1. Both sides of the adjusting component 6 are connected to the opposite surfaces of the two adjusting plates 3 to support and adjust the rotation of the adjusting plates 3 along the rotating shafts 5 to realize unfolding or folding. Grooves 8 are respectively formed on both sides of the front and back of the support frame 1. Driving components 9 are respectively fixedly installed in the two grooves 8 on the same side in the front and back. The bottom end of the driving component 9 is installed at the bottom of the inner wall of the groove 8 through a bushing. A sliding component 10 is slidably connected in each of the two grooves 8 in the front and back. The driving component 9 penetrates through one end of the sliding component 10. The other end of the sliding component 10 penetrates and slides on a vertical rod 11. Both ends of the vertical rod 11 are fixed in the groove 8 far from the driving component 9. The driving component 9 drives the sliding component to slide up and down along the vertical rod 11. A hollow shaft 14 is rotatably connected inside the sliding component 10 through a bushing. A plurality of water outlet holes 15 are formed outside the hollow shaft 14. The water outlet holes 15 are communicated with the inside of the hollow shaft 14. A cleaning brush 16 is fixed outside the hollow shaft 14.

[0036] One end of the hollow shaft 14 penetrates through the sliding component 10 and is clamped with a rotary joint 17. A water guide pipe 18 is sleeved inside the rotary joint 17. The hollow shaft 14 is communicated with the water guide pipe 18 through the rotary joint 17. While the hollow shaft 14 rotates, it will not affect the normal conduction work between the water guide pipe 18 and the inside of the hollow shaft 14, ensuring that the water inside the hollow shaft 14 continuously sprays out from the external water outlet holes 15.

[0037] As a further solution of the present invention, the adjusting component 6 includes a support plate 601. Slideways 7 are respectively formed on both sides of the inner wall of the support frame 1. The left and right sides of the support plate 601 are slidably connected in the two slideways 7. A multi-stage electric hydraulic rod 602 is fixedly installed at the bottom of the support plate 601. Side plates 603 are respectively fixed on both sides of the multi-stage electric hydraulic rod 602. The side of the side plate 603 far from the multi-stage electric hydraulic rod 602 is lapped with the adjusting plate 3. Limiting rods 604 respectively penetrate and slide on both sides of the support plate 601. Both ends of the limiting rods 604 are fixed at the top and bottom of the inner wall of the support frame 1.

[0038] During operation, the multi-stage electric hydraulic rod 602 extends to drive the support plate 601 to move upward. The support plate 601 is limited by the two slideways 7, and the support plate 601 can slide outside the two limiting rods 604. The support plate 601 is limited by the limiting rods 604, thereby improving the stability of the vertical movement of the support plate 601.

[0039] Control the multi-stage electric hydraulic rod 602 to contract and pull the pallet 601 to move downward. The pallet 601 then pulls the adjusting plate 3 to deflect through the sliding cylinder 605 and the sliding rod 606, so that the bottoms of the two adjusting plates 3 approach each other until they contact the side plate 603 on one side of the multi-stage electric hydraulic rod 602. The side plate 603 supports and limits the adjusting plate 3, so that the adjusting plate 3 and the photovoltaic panel 4 always remain vertical, which is beneficial to the falling of dust and impurities.

[0040] As a further solution of the present invention, both sides of the top of the pallet 601 are respectively rotatably connected with sliding cylinders 605 through pin shafts. A sliding rod 606 is slidably inserted into the sliding cylinder 605. The top end of the sliding rod 606 is rotatably connected to the upper part of one side of the adjusting plate 3 through a pin shaft. A guide rod 607 is fixed to the bottom end of the sliding rod 606. A chute 608 is opened at the bottom of the inner wall of the sliding cylinder 605. The guide rod 607 is slidably inserted into the chute 608. A spring 609 is sleeved outside the guide rod 607;

[0041] During operation, the adjusting plate 3 squeezes the sliding rod 606 through the pin shaft. The sliding rod 606 then slides inside the sliding cylinder 605. At the same time, the guide rod 607 at the bottom end of the sliding rod 606 slides inside the chute 608 of the sliding cylinder 605, which plays a role in limiting the sliding rod 606 and improves the stability of the sliding rod 606 in supporting the adjusting plate 3. And the spring 609 is squeezed during the movement of the sliding rod 606;

[0042] The sliding rod 606 is supported by the elastic force of the spring 609, which provides an upward force to the sliding rod 606 and supports the adjusting plate 3, playing a role in supporting and buffering the photovoltaic panel 4 inside the adjusting plate 3, preventing the photovoltaic panel 4 from being severely damaged and deformed under external forces, and thus improving the anti-seismic protection effect on the photovoltaic panel 4.

[0043] As a further solution of the present invention, the driving assembly 9 includes a motor 902. The motor 902 is fixed to the top of the inner wall of the groove 8. A lead screw 901 is fixed to the output shaft of the motor 902. The lead screw 901 penetrates and is threadedly connected to the sliding assembly 10, and the bottom end of the lead screw 901 is rotatably connected to the bottom of the inner wall of the groove 8 through a bushing; the sliding assembly 10 includes two sliding seats 101. The two sliding seats 101 are respectively slidably connected to two grooves 8 on the same surface. Two ear plates 102 are fixed to the sides of the two sliding seats 101 away from each other. A sliding sleeve 103 and a nut 104 are respectively fixed between the two ear plates 102 on the same side. The lead screw 901 is threadedly connected to the nut 104. The vertical rod 11 passes through and slides inside the sliding sleeve 103;

[0044] During operation, when the lead screw 901 rotates inside the nut 104, the nut 104 drives the slide block 101 on one side to slide inside the groove 8. The two slide blocks 101 are sleeved with the two end parts of the hollow shaft 14 through a bushing, so that the two slide blocks 101 drive the hollow shaft 14 to move downward, facilitating the free adjustment of the position of the hollow shaft 14. Moreover, the vertical rod 11 supports and guides the sliding sleeve 103, improving the stability of the synchronous movement of the two slide blocks 101.

[0045] As a further solution of the present invention, a sliding hole 13 is formed on one side of the inner wall of the groove 8. The protruding end of the ear plate 102 penetrates and slides inside the sliding hole 13. Inside the slide block 101, a gear ring 105 and a gear 106 are rotatably connected through a bushing. The gear 106 is meshed and connected with the gear 106. The gear ring 105 is clamped outside the hollow shaft 14. A plurality of teeth 12 are fixed on the inner wall of the groove 8. The gear 106 is meshed and connected with the teeth 12 inside the groove 8.

[0046] During operation, the ear plate 102 is limited through the sliding hole 13, improving the movement stability of the slide block 101. During the meshing process of the gear 106 and the teeth 12, the gear 106 rotates counterclockwise. Then the gear 106 drives the hollow shaft 14 to rotate clockwise through the gear ring 105, so that during the downward movement of the hollow shaft 14, the external cleaning brush 16 is driven to rotate clockwise and contact the photovoltaic panel 4 inside the adjusting plate 3. The hollow shaft 14 is rotatably connected inside the two slide blocks 101 through a bushing, and the bushing is clamped inside the slide block 101. The hollow shaft 14 is limited and supported through the bushing, enabling the hollow shaft 14 to move synchronously with the slide block 101.

[0047] During the process of the slide block 101 driving the hollow shaft 14 to move downward, one end of the water guide pipe 18 is connected with the end part of the hollow shaft 14 through a rotary joint 17, enabling the water guide pipe 18 to move along with the slide block 101. The water guide pipe 18 can be a corrugated pipe or a rubber hose. The corrugated pipe or the rubber hose has good flexibility and stretchability, and can adapt to the movement and bending deformation of the slide block 101 to a certain extent, so that the water guide pipe 18 will not cause the water flow channel to be severely squeezed or blocked due to folding.

[0048] The adjusting plate 3 is supported and limited through the side plate 603, so that the adjusting plate 3 and the photovoltaic panel 4 always remain in a vertical state. Only when the photovoltaic panel 4 is in a vertical state and parallel to the support frame 1, the hollow shaft 14 will drive the cleaning brush 16 to clean the photovoltaic panel. When the photovoltaic panel 4 is in an inclined state, no cleaning work is carried out. Moreover, the hollow shaft 14 is located in front of the support frame 1 and there is no direct connection relationship. When the photovoltaic panel 4 is in a vertical state, it does not affect the normal downward movement of the hollow shaft 14.

[0049] During the process of the hollow shaft 14 driving the cleaning brush 16 to move downward, the cleaning brush 16 rotates clockwise to increase the frictional force between the cleaning brush 16 and the photovoltaic panel 4, so that the cleaning brush 16 scrapes the photovoltaic panel 4 from top to bottom, improving the scraping effect.

[0050] As a further solution of the present invention, a water pump 19 is connected to the bottom end of the water guide pipe 18. The water pump 19 is fixed on one side of the support frame 1. A baffle 20 is provided above the hollow shaft 14 and the cleaning brush 16. The baffle 20 is designed in an L shape and fixed on the top of the support frame 1. The sliding seat 101 drives the hollow shaft 14 and the cleaning brush 16 to move upward and be located above the adjusting plate 3, so that the hollow shaft 14 and the cleaning brush 16 are located within the L-shaped baffle 20. When the cleaning work is not carried out, the hollow shaft 14 and the cleaning brush 16 are protected.

[0051] During operation, the water guide pipe 18 introduces water into the interior of the hollow shaft 14 through the rotary joint 17, so that the water ejected from the water outlet holes 15 outside the hollow shaft 14 will wet the cleaning brush 16, improving the scrubbing ability of the cleaning brush 16. At the same time, the water ejected from the water outlet holes 15 will soften the dust and impurities adhering to the surface of the photovoltaic panel 4, and cooperate with the continuous rotation of the cleaning brush 16 to improve the cleaning effect on the photovoltaic panel 4.

[0052] A usage method of an adjustable distributed photovoltaic power generation device, the usage method includes the following steps:

[0053] When adjusting the photovoltaic power generation device, control the multi-stage electro-hydraulic rod 602 to extend to drive the support plate 601 to move upward. The support plate 601 is limited by the two sliding ways 7 to improve the stability of the vertical movement of the support plate 601. During the upward movement of the support plate 601, a plurality of sliding cylinders 605 will be pushed by the pin shaft. When the sliding cylinder 605 drives the sliding rod 606 to move, the bottom end of the sliding cylinder 605 rotates on the top of the support plate 601 through the pin shaft, and the top end of the sliding rod 606 rotates above one side of the adjusting plate 3 through the pin shaft. When the adjusting plate 3 is pressed, the top of the adjusting plate 3 drives the rotating shaft 5 to rotate inside the support frame 1, that is, the adjusting plate 3 drives the photovoltaic panel 4 to perform angle adjustment, so that the photovoltaic panel 4 receives solar energy to the greatest extent for photovoltaic power generation.

[0054] When the adjusting plate 3 or the photovoltaic panel 4 is subjected to an external force due to the fall of a heavy object, the adjusting plate 3 squeezes the sliding rod 606 through the pin shaft. The sliding rod 606 then slides inside the sliding cylinder 605. At the same time, the guide rod 607 at the bottom of the sliding rod 606 slides inside the chute 608 inside the sliding cylinder 605, which plays a role in limiting the sliding rod 606, improving the stability of the support of the sliding rod 606 for the adjusting plate 3. And during the movement of the sliding rod 606, the spring 609 is squeezed. The elastic force of the spring 609 supports the sliding rod 606, providing an upward force to the sliding rod 606 and supporting the adjusting plate 3, playing a role in supporting and buffering the photovoltaic panel 4 inside the adjusting plate 3, preventing the photovoltaic panel 4 from being severely damaged and deformed under external forces, and thus improving the anti-seismic protection effect on the photovoltaic panel 4;

[0055] When cleaning the surface of the photovoltaic panel 4, control the multi-stage electric hydraulic rod 602 to contract and pull the tray 601 downward. The tray 601 then pulls the adjusting plate 3 to deflect through the sliding cylinder 605 and the sliding rod 606, so that the bottoms of the two adjusting plates 3 approach each other until they contact the side plate 603 on one side of the multi-stage electric hydraulic rod 602. The side plate 603 supports and limits the adjusting plate 3, keeping the adjusting plate 3 and the photovoltaic panel 4 in a vertical state all the time, which is beneficial to the falling of dust and impurities. Control the motor 902 to work and drive the lead screw 901 to rotate. During the rotation of the lead screw 901 inside the nut 104, the nut 104 will drive the sliding seat 101 on one side to slide inside the groove 8. The two sliding seats 101 are sleeved with the two ends of the hollow shaft 14 through the bushing, so that the two sliding seats 101 will drive the hollow shaft 14 to move downward. During the downward movement of the sliding seat 101, the gear 106 is driven to move. When the gear 106 meshes with the tooth 12, the gear 106 will rotate counterclockwise. The gear 106 then drives the hollow shaft 14 to rotate clockwise through the toothed ring 105, so that the hollow shaft 14 drives the external cleaning brush 16 to rotate clockwise and contact the photovoltaic panel 4 inside the adjusting plate 3 during the downward movement, achieving the purpose of scraping the photovoltaic panel 4. During the downward movement of the hollow shaft 14 driving the cleaning brush 16, the cleaning brush 16 rotates clockwise, so as to increase the friction between the cleaning brush 16 and the photovoltaic panel 4, and the cleaning brush 16 scrapes the photovoltaic panel 4 from top to bottom, improving the scraping effect;

[0056] At the same time, the water pump 19 is controlled to work. The water pump 19 pumps water from the water source and conducts the water into the water guide pipe 18. The water guide pipe 18 conducts the water into the interior of the hollow shaft 14 through the rotary joint 17. Moreover, the hollow shaft 14 is connected to the water guide pipe 18 through the rotary joint 17. While the hollow shaft 14 rotates, it does not affect the normal conduction work between the water guide pipe 18 and the interior of the hollow shaft 14, ensuring that the water inside the hollow shaft 14 continuously sprays out from the external water outlet holes 15. The water sprayed out from the water outlet holes 15 will wet the cleaning brush 16, improving the scrubbing ability of the cleaning brush 16. At the same time, the water sprayed out from the water outlet holes 15 will soften the dust and impurities adhering to the surface of the photovoltaic panel 4. In cooperation with the continuous rotation of the cleaning brush 16, and the lengths of the hollow shaft 14 and the cleaning brush 16 are greater than the width of the photovoltaic panel 4. During the up and down movement of the hollow shaft 14, the cleaning brush 16 will fully cover the surface of the photovoltaic panel 4, further improving the cleaning effect and cleaning efficiency of the photovoltaic panel 4. Moreover, the photovoltaic panel 4 is in a vertical state at this time, and the dirt generated by cleaning will flow down along the photovoltaic panel 4, preventing the dirt from adhering to the photovoltaic panel 4 and causing secondary pollution to it. When the hollow shaft 14 drives the cleaning brush 16 to move below the adjusting plate 3, the motor 902 is controlled to work in the reverse direction. Similarly, the sliding seat 101 will drive the hollow shaft 14 and the cleaning brush 16 to move upward and be located above the adjusting plate 3, so that the hollow shaft 14 and the cleaning brush 16 are located inside the baffle 20 with an L-shaped design. When the cleaning work is not carried out, the hollow shaft 14 and the cleaning brush 16 are protected, and at the same time, it does not affect the normal adjustment work of the adjusting plate 3 and the photovoltaic panel 4.

8. A method for using an adjustable distributed photovoltaic power generation device, which is an adjustable distributed photovoltaic power generation device according to any one of claims 1-7, characterized in that, The using method includes the following steps: When adjusting the photovoltaic power generation device, control the multi-stage electro-hydraulic rod (602) to extend to drive the support plate (601) to move upward. The two sliding ways (7) are used to limit the support plate (601) to improve the stability of the vertical movement of the support plate (601). During the upward movement of the support plate (601), a plurality of sliding cylinders (605) will be pushed by the pin shaft. When the sliding cylinder (605) drives the sliding rod (606) to move, the bottom end of the sliding cylinder (605) rotates on the top of the support plate (601) through the pin shaft, and the top end of the sliding rod (606) rotates above one side of the adjusting plate (3) through the pin shaft. When the adjusting plate (3) is pressed, the top of the adjusting plate (3) drives the rotating shaft (5) to rotate inside the support frame (1), that is, the adjusting plate (3) drives the photovoltaic panel (4) to adjust the angle, so that the photovoltaic panel (4) receives solar energy to the greatest extent for photovoltaic power generation; When the adjusting plate (3) or the photovoltaic panel (4) is subjected to an external force due to the fall of a heavy object, the adjusting plate (3) squeezes the sliding rod (606) through the pin shaft. The sliding rod (606) slides inside the sliding cylinder (605). At the same time, the guiding rod (607) at the bottom of the sliding rod (606) slides inside the chute (608) inside the sliding cylinder (605), playing a role in limiting the sliding rod (606), improving the stability of the support of the sliding rod (606) for the adjusting plate (3), and squeezing the spring (609) during the movement of the sliding rod (606). The elastic force of the spring (609) supports the sliding rod (606), providing an upward force to the sliding rod (606) and supporting the adjusting plate (3), playing a role in supporting and buffering the photovoltaic panel (4) inside the adjusting plate (3), preventing the photovoltaic panel (4) from being severely damaged and deformed under external forces, and thus improving the anti-seismic protection effect on the photovoltaic panel (4); When cleaning the surface of the photovoltaic panel (4), control the multi-stage electric hydraulic rod (602) to contract and pull the support plate (601) to move downward. The support plate (601) then pulls the adjusting plate (3) to deflect through the sliding cylinder (605) and the sliding rod (606), so that the bottoms of the two adjusting plates (3) approach each other until they contact the side plate (603) on one side of the multi-stage electric hydraulic rod (602). The side plate (603) supports and limits the adjusting plate (3), keeping the adjusting plate (3) and the photovoltaic panel (4) always in a vertical state, which is conducive to the fall of dust and impurities. Control the motor (902) to work and drive the lead screw (901) to rotate. During the rotation of the lead screw (901) inside the nut (104), the nut (104) will drive the sliding seat (101) on one side to slide inside the groove (8). The two sliding seats (101) are sleeved with the two ends of the hollow shaft (14) through the bushing, so that the two sliding seats (101) will drive the hollow shaft (14) to move downward. During the downward movement of the sliding seat (101), the gear (106) is driven to move. When the gear (106) meshes with the tooth (12), the gear (106) will rotate counterclockwise. The gear (106) then drives the hollow shaft (14) to rotate clockwise through the toothed ring (105), so that the hollow shaft (14) drives the external cleaning brush (16) to rotate clockwise and contact the photovoltaic panel (4) inside the adjusting plate (3) during the downward movement, achieving the purpose of scraping the photovoltaic panel (4). During the downward movement of the hollow shaft (14) driving the cleaning brush (16), the cleaning brush (16) rotates clockwise, so as to increase the friction force between the cleaning brush (16) and the photovoltaic panel (4), and make the cleaning brush (16) scrape the photovoltaic panel (4) from top to bottom, improving the scraping effect; Meanwhile, the water pump (19) is controlled to work. The water pump (19) pumps water from the water source and conducts the water into the water guide pipe (18). The water guide pipe (18) conducts the water into the inside of the hollow shaft (14) through the rotary joint (17). Moreover, the hollow shaft (14) is connected to the water guide pipe (18) through the rotary joint (17). While the hollow shaft (14) rotates, it will not affect the normal conduction work between the water guide pipe (18) and the inside of the hollow shaft (14), ensuring that the water inside the hollow shaft (14) continuously sprays out from the external water outlet holes (15). The water sprayed out from the water outlet holes (15) will wet the cleaning brush (16), improving the scrubbing ability of the cleaning brush (16). At the same time, the water sprayed out from the water outlet holes (15) will soften the dust and impurities attached to the surface of the photovoltaic panel (4). In cooperation with the continuous rotation of the cleaning brush (16), and the lengths of the hollow shaft (14) and the cleaning brush (16) are greater than the width of the photovoltaic panel (4). During the up-and-down movement of the hollow shaft (14), the cleaning brush (16) will fully cover the surface of the photovoltaic panel (4), further improving the cleaning effect and cleaning efficiency of the photovoltaic panel (4). Moreover, the photovoltaic panel (4) is in a vertical state at this time, and the dirt generated during cleaning will flow down along the photovoltaic panel (4), preventing the dirt from adhering to the photovoltaic panel (4) and causing secondary pollution to it. When the hollow shaft (14) drives the cleaning brush (16) to move below the adjusting plate (3), the motor (902) is controlled to work in the reverse direction. Similarly, the sliding seat (101) will drive the hollow shaft (14) and the cleaning brush (16) to move upward and be located above the adjusting plate (3), so that the hollow shaft (14) and the cleaning brush (16) are located inside the L-shaped baffle (20). When the cleaning work is not carried out, the hollow shaft (14) and the cleaning brush (16) are protected, and at the same time, it does not affect the normal adjustment work of the adjusting plate (3) and the photovoltaic panel (4).
