It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are made of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0015] Compared with the prior art, the present invention has the following beneficial effects: Firstly, the overall height of the present invention is reduced, and the photovoltaic panel is installed by four abutment components.

When the wind is too strong, the lifting plate is driven downward by the driving mechanism, and the lifting plate drives the lateral angle adjustment mechanism, the longitudinal angle adjustment mechanism, the clamping and fixing mechanism, and the photovoltaic panel to retract into the circular protective cover.

[0019] Fifthly, when the wind force is too strong, the shaking force of the present invention will also increase. The shaking force can not only increase the amplitude of the reciprocating movement of the first movable handle in the sliding cavity, but also increase the amplitude of the reciprocating movement of the second movable handle in the telescopic cylinder. This will cause the speed of gas entering the air compression tank to be accelerated. The gas flow rate monitor can detect this situation in time, so that the airbag can perform exhaust operation in time. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-8 , the above technical solutions will be described in detail by the following embodiments of the present invention: A distributed rooftop photovoltaic structure includes a photovoltaic panel 1, a bottom plate 2, and a circular ring protective cover 3. A controller 21 is provided on the top of the bottom plate 2. A lifting plate 31 and a driving mechanism for driving the lifting of the lifting plate 31 are provided inside the circular ring protective cover 3. A cleaning mechanism 4 for cleaning the surface of the photovoltaic panel 1 and a lateral angle adjustment mechanism 5 for adjusting the angle of the photovoltaic panel 1 are provided on the top of the lifting plate 31. A longitudinal angle adjustment mechanism 6 for adjusting the angle of the photovoltaic panel 1 is provided on the lateral angle adjustment mechanism 5. A clamping and fixing mechanism for clamping and fixing the photovoltaic panel 1 is provided on the longitudinal angle adjustment mechanism 6. The clamping and fixing mechanism includes a circular frame body 7 and four abutting members 8 with a buffering function. The circular frame body 7 is fixedly connected to the top of the longitudinal angle adjustment mechanism 6. The four abutting members 8 are arranged on the circular frame body 7 at equal angles along the circumference of the circular frame body 7. The photovoltaic panel 1 is fixedly connected to the four abutting members 8. The driving mechanism, the circular frame body 7, and the four abutting members 8 are all connected to the cleaning mechanism 4.

[0024] The overall height of the present invention is reduced. The photovoltaic panel 1 is installed through the four abutting members 8. Since the abutting members 8 have a buffering function, they can offset the shaking force of the photovoltaic panel 1, invisibly improving the stability. When the wind force is too large, the driving mechanism drives the lifting plate 31 to move downward. The lifting plate 31 drives the lateral angle adjustment mechanism 5, the longitudinal angle adjustment mechanism 6, the clamping and fixing mechanism, and the photovoltaic panel 1 to retract into the circular ring protective cover 3. The circular ring protective cover 3 can protect the photovoltaic panel 1 and prevent the photovoltaic panel 1 from being accidentally damaged.

[0025] The present invention can also adjust the placement angle of the photovoltaic panel 1 in real time through the cooperation of the lateral angle adjustment mechanism 5 and the longitudinal angle adjustment mechanism 6. The lateral angle adjustment mechanism 5 includes a bottom rotating seat 51, a first motor 52, and a top plate 53. A vertically arranged rotating shaft 511 is rotatably provided on the bottom rotating seat 51. A driven gear 512 is provided on the rotating shaft 511. A driving gear 521 is provided on the output end of the first motor 52. The bottom rotating seat 51 and the first motor 52 are both provided on the top of the lifting plate 31. The first motor 52 is located beside the bottom rotating seat 51. The driven gear 512 meshes with the driving gear 521. The top plate 53 is provided on the top of the rotating shaft 511. The longitudinal angle adjustment mechanism 6 is provided on the top plate 53.

[0026] Furthermore, the longitudinal angle adjustment mechanism 6 includes two first rotating seats 61, an adjustment shaft 62, a second motor 63, a worm gear 64, a worm 65, two arc-shaped plates 66, and two clamping transmission components 67. A vertically arranged fixed plate 531 is provided on the side wall of the top plate 53, and two symmetrically arranged second rotating seats 532 are provided in the middle of the top plate 53. The two first rotating seats 61 are symmetrically arranged on the top of the top plate 53. The adjustment shaft 62 is rotatably arranged on the two first rotating seats 61. The second motor 63 is horizontally arranged on the fixed plate 531. The worm gear 64 is arranged on the adjustment shaft 62. The worm 65 is rotatably arranged on the two second rotating seats 532. The worm 65 meshes with the worm gear 64. The output end of the second motor 63 is fixedly connected to the worm 65. The two arc-shaped plates 66 are symmetrically arranged at the bottom of the circular frame 7. The two clamping transmission components 67 are symmetrically arranged on both sides of the adjustment shaft 62. The two clamping transmission components 67 are respectively in transmission connection with the two arc-shaped plates 66.

[0027] Still further, the clamping transmission component 67 includes an arc-shaped rack 671, a transmission gear 672, and a side plate 673. Two symmetrically arranged rotating holes are formed in the side plate 673. A roller shaft 6731 is rotatably arranged in one of the rotating holes. An abutting wheel 6732 is arranged on the roller shaft 6731. A connecting rod 6733 is arranged on the back of the side plate 673. The arc-shaped rack 671 is arranged on the side wall of the arc-shaped plate 66. The adjustment shaft 62 is rotatably arranged in the other rotating hole. The transmission gear 672 is arranged on the adjustment shaft 62. The transmission gear 672 meshes with the arc-shaped rack 671. The connecting rod 6733 is arranged on the side wall of the first rotating seat 61. The abutting wheel 6732 abuts against the outer wall of the arc-shaped rack 671.

[0028] The first motor 52 drives the driving gear 521 to rotate. The driving gear 521 drives the driven gear 512 to rotate. The driven gear 512 drives the rotating shaft 511 to rotate. The rotating shaft 511 drives the top plate 53 to rotate. The top plate 53 drives the longitudinal angle adjustment mechanism 6, the circular frame 7, the four abutting components 8, and the photovoltaic panel 1 to rotate synchronously, thereby realizing the adjustment of the lateral angle of the photovoltaic panel 1. The second motor 63 drives the worm 65 to rotate. The worm 65 drives the worm gear 64 to rotate. The worm gear 64 drives the adjustment shaft 62 to rotate. The adjustment shaft 62 drives the two transmission gears 672 to rotate synchronously. The transmission gear 672 and the arc-shaped rack 671 cooperate to drive the arc-shaped plate 66 to rotate longitudinally around the center of the arc-shaped plate 66. The arc-shaped plate 66 drives the circular frame 7 and the photovoltaic panel 1 to adjust the longitudinal angle. While the arc-shaped rack 671 is rotating, the abutting wheel 6732 also rolls on the outer wall of the arc-shaped rack 671, so that the transmission gear 672 and the abutting wheel 6732 always form clamping and limiting.

[0029] This device can clean the photovoltaic panel 1 through the cleaning mechanism 4. The cleaning mechanism 4 includes an air compression tank body 41, a vertical rod 42, and a jet head 43. An air outlet pipe is provided at the top of the air compression tank body 41, and a first electromagnetic valve 411 is provided on the air outlet pipe. An installation sleeve 421 is provided at the top of the vertical rod 42. The air compression tank body 41 is arranged on the top of the bottom plate 2, the vertical rod 42 is arranged on the top of the lifting plate 31, and the jet head 43 is fixedly connected to the installation sleeve 421. The jet head 43 is communicated with the air outlet pipe through a pipeline.

[0030] When the first electromagnetic valve 411 works to open the air outlet pipe, the gas in the air compression tank body 41 can flow into the jet head 43. Then, the jet head 43 can blow air on the photovoltaic panel 1, and the surface of the photovoltaic panel 1 can be automatically cleaned by using high-pressure gas. Of course, when cleaning the photovoltaic panel 1, the photovoltaic panel 1 is first adjusted to a horizontal state through the longitudinal angle adjustment mechanism 6. When the jet head 43 is blowing air, the transverse angle adjustment mechanism 5 works synchronously, so that the surface of the photovoltaic panel 1 can be thoroughly cleaned.

[0031] The lifting plate 31 can be driven to lift through the driving mechanism. The driving mechanism includes an air bag 9. An air inlet pipe 91 and an exhaust pipe 92 are provided on the air bag 9. Second electromagnetic valves 93 are provided on both the air inlet pipe 91 and the exhaust pipe 92. A guide block 311 is provided on the outer wall of the lifting plate 31, and a guide groove that is slidably matched with the guide block 311 is provided on the inner wall of the circular ring protective cover 3. The air bag 9 is arranged on the bottom plate 2, and the air bag 9 is located directly below the lifting plate 31. The air inlet pipe 91 and the exhaust pipe 92 both penetrate through the circular ring protective cover 3, and the air inlet pipe 91 is communicated with the air compression tank body 41.

[0032] When the second electromagnetic valve 93 on the air inlet pipe 91 is opened, the compressed gas in the air compression tank body 41 can flow into the air bag 9. The air bag 9 can gradually expand, and the air bag 9 can abut against the lifting plate 31 to move it upward. The lifting plate 31 drives the transverse angle adjustment mechanism 5, the longitudinal angle adjustment mechanism 6, the clamping and fixing mechanism, and the photovoltaic panel 1 to move upward synchronously. The photovoltaic panel 1 can be completely exposed from the circular ring protective cover 3. Then, the second electromagnetic valve 93 on the air inlet pipe 91 is closed. When the wind force is too strong, the second electromagnetic valve 93 on the exhaust pipe 92 is opened. The gravity of the lifting plate 31, the transverse angle adjustment mechanism 5, the longitudinal angle adjustment mechanism 6, the clamping and fixing mechanism, and the photovoltaic panel 1 can exert pressure on the air bag 9. The gas in the air bag 9 can be quickly discharged through the exhaust pipe 92. Then, the transverse angle adjustment mechanism 5, the longitudinal angle adjustment mechanism 6, the clamping and fixing mechanism, and the photovoltaic panel 1 can retract into the circular ring protective cover 3. The circular ring protective cover 3 can protect the photovoltaic panel 1. The cooperation between the guide block 311 and the guide groove can improve the stable balance of the lifting plate 31 during the lifting process.

[0033] The four abutting components 8 can provide buffering forces for the photovoltaic panel 1 in the front, back, left, and right directions, improving the installation stability of the photovoltaic panel 1. The abutting component 8 includes a first movable handle 81 and a mounting post 82. A first spring 83 is provided at the tail end of the first movable handle 81, a first telescopic rod 84 is provided at the head end of the first movable handle 81, an L-shaped bearing plate 85 is provided at the head end of the first telescopic rod 84, a sliding cavity 821 that is slidably engaged with the first movable handle 81 is formed at the tail end of the mounting post 82, and a telescopic groove 822 that is slidably engaged with the first telescopic rod 84 is formed at the head end of the sliding cavity 821. The mounting post 82 is horizontally and fixedly connected to the inner wall of the circular frame 7, and the photovoltaic panel 1 is fixed to the four L-shaped bearing plates 85.

[0034] The circular frame 7 includes an upper ring plate 71 and a lower ring plate 72. The vertical cross-sections of the upper ring plate 71 and the lower ring plate 72 are both L-shaped. A plurality of second telescopic rods 711 that are arranged at equal angles around its circumference are provided on the inner top wall of the upper ring plate 71. A second spring 712 is sleeved on the second telescopic rod 711, and a second movable handle 713 is provided at the bottom of the second telescopic rod 711. A plurality of guide holes that are slidably engaged with the second telescopic rods 711 are formed on the inner bottom wall of the lower ring plate 72. An expansion and contraction activity cavity 73 is formed between the upper ring plate 71 and the lower ring plate 72. The two ends of the second spring 712 are respectively in contact with the inner top wall of the upper ring plate 71 and the inner bottom wall of the lower ring plate 72. The mounting post 82 is horizontally and fixedly connected to the upper ring plate 71.

[0035] In the case of wind, when the wind acts on the photovoltaic panel 1 and generates a swaying force in the front, back, left, or right direction, the swaying force can be transmitted to the first telescopic rod 84 through the L-shaped bearing plate 85. The first telescopic rod 84 transmits the force to the first movable handle 81, and the first movable handle 81 then transmits the force to the first spring 83. The elastic force of the first spring 83 can offset most of the swaying force. When the wind acts on the photovoltaic panel 1 and generates a swaying force in the up and down direction, the swaying force can be transmitted to the upper ring plate 71 through the L-shaped bearing plate 85, the first telescopic rod 84, and the mounting post 82. The upper ring plate 71 transmits the force to all the second springs 712. The elastic force of the second springs 712 can offset most of the swaying force, thereby improving the installation stability of the photovoltaic panel 1.

[0036] The mounting post 82 is provided with a first air inlet 823 and a first air outlet 824 that communicate with the sliding cavity 821. A first intake check valve is provided in the first air inlet 823, and a first outlet check valve is provided in the first air outlet 824. Two symmetrically arranged arc-shaped rotating air pipes 10 are provided directly below the lower ring plate 72. A plurality of vertically arranged telescopic cylinders 101 that are slidably engaged with the second movable handle 713 are connected to the top of the arc-shaped rotating air pipe 10. A second outlet check valve 103 is provided at the bottom end of the telescopic cylinder 101. A second air inlet 102 that communicates with it is provided on the outer wall of the telescopic cylinder 101. A second intake check valve 104 is provided in the second air inlet 102. A second air outlet 105 is provided at the bottom of the arc-shaped rotating air pipe 10. A gas flow rate monitor 412 that communicates with its interior is provided on the air compression tank body 41. The telescopic cylinder 101 is fixedly connected to the bottom of the lower ring plate 72. The first air outlet 824 is communicated with one of the arc-shaped rotating air pipes 10 through a pipeline. The second air outlet 105 is communicated with the gas flow rate monitor 412 through a pipeline.

[0037] The shaking force in the front-back or left-right direction enables the first movable handle 81 to generate a short-distance displacement within the sliding cavity 821. The first movable handle 81 exerts a squeezing force on the sliding cavity 821, squeezing the air inside the sliding cavity 821. Through the cooperation of the first intake one-way valve and the first outlet one-way valve, the air inside the sliding cavity 821 can be squeezed into the first outlet port 824. Then, the squeezed air enters the arc-shaped rotating air pipe 10 through the pipeline. After that, the arc-shaped rotating air pipe 10 discharges the air from the second outlet port 105. Then, the air passes through the second outlet port 105, the pipeline, and the gas flow rate monitor 412 and enters the air compression tank body 41. When the elastic force of the first spring 83 drives the first movable handle 81 to reset, the first movable handle 81 can generate a pulling force within the sliding cavity 821. Through the cooperation of the first intake one-way valve and the first outlet one-way valve, external air can enter the sliding cavity 821 through the first intake port 823. The shaking force in the up-down direction enables the second movable handle 713 to generate a short-distance displacement within the telescopic cylinder 101. The second movable handle 713 exerts a squeezing force on the inside of the telescopic cylinder 101. Through the cooperation of the second intake one-way valve 104 and the second outlet one-way valve 103, the air inside the telescopic cylinder 101 can be squeezed into the arc-shaped rotating air pipe 10. Then, this air is also squeezed into the air compression tank body 41. When the elastic force of the second spring 712 drives the upper ring plate 71 to reset, the upper ring plate 71 can drive the second telescopic rod 711 and the second movable handle 713 to reset synchronously. The second movable handle 713 generates a pulling force on the telescopic cylinder 101. Through the cooperation of the second intake one-way valve 104 and the second outlet one-way valve 103, external air can enter the telescopic cylinder 101 through the second intake port 102. When the wind force is too strong, the shaking force also increases. The elastic forces of the first spring 83 and the second spring 712 can only offset a small part of the shaking force. The shaking force not only increases the amplitude of the reciprocating movement of the first movable handle 81 back and forth within the sliding cavity 821 but also increases the amplitude of the reciprocating movement of the second movable handle 713 up and down within the telescopic cylinder 101. This causes the speed of the gas entering the air compression tank body 41 to also increase. After the gas flow rate monitor 412 detects this situation, the controller 21 controls the second solenoid valve 93 on the exhaust pipe 92 to open, so that the photovoltaic panel 1 retracts into the circular protection cover 3. After the photovoltaic panel 1 retracts, the photovoltaic panel 1 is adjusted to a horizontal state through the longitudinal angle adjustment mechanism 6.
