Based on 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.

[0032] like Figure 1 , Figure 2 As shown, the present invention provides a solar photovoltaic power generation system, including a support frame 1, a controller 11 is arranged on one side of the support leg on the support frame 1, and a support rod 12 is fixedly arranged on the upper part of the support frame 1, and a rotating sleeve 13 is sleeved on both ends of the support rod 12, and a photovoltaic panel 14 is fixedly connected to the top of the rotating sleeve 13; an angle adjustment mechanism 2 is arranged on the lower end surface of the photovoltaic panel 14; a snap mechanism 3 is arranged on the upper part of the support frame 1; a moving mechanism 4 is arranged on the top of the support frame 1; and a cleaning mechanism is directly opposite to the upper end surface of the photovoltaic panel 14.

[0033] like Figure 2 , Figure 3 As shown, the angle adjustment mechanism 2 includes a base plate 21, a first electric cylinder 22 is fixedly connected to one side of the upper end surface of the base plate 21, a first push rod 23 is connected to the output end of the first electric cylinder 22, the first push rod 23 is rotatably connected to the photovoltaic panel 14 through a first rotating frame 141, a deployment plate 24 is rotatably connected to one side of the lower end surface of the photovoltaic panel 14 through a second rotating frame 142, a sliding groove 211 is slidably matched at the lower part of the deployment plate 24, and the sliding groove 211 is opened in the middle of the upper end surface of the base plate 21, a first push rod 25 and a second push rod 26 are fixedly connected to the two side surfaces of the photovoltaic panel 14, and the outer side of the second push rod 26 abuts against a push groove 271 opened on one side of the push plate 27.

[0034] The above scheme is adopted: the first electric cylinder 22 drives the first push rod 23 to move upward, and one side of the photovoltaic panel 14 is subjected to force through the transmission of the first rotating frame. The photovoltaic panel 14 is subjected to force and rotates counterclockwise on the outside of the support rod 12 through the rotating sleeve 13. During the rotation of the photovoltaic panel 14, the other side of the photovoltaic panel 14 is pressed downward on the expansion plate 24 through the second rotating frame 142. The expansion plate 24 is subjected to force and its lower part slides to one side along the sliding groove, so that the expansion plate 24 is gradually folded downward, which effectively ensures that the photovoltaic panel 14 is more stable and protected during rotation, and will not cause serious damage due to the impact of foreign objects.

[0035] like Figure 4 , Figure 5As shown, the snap mechanism 3 includes a snap shell 31 fixedly connected to the upper part of the supporting leg on the supporting frame 1, guide rails 311 are provided on both sides of the snap shell 31, and a first rotating circular plate 32 is rotatably connected to the inside of the snap shell 31 through a first fixed rod, a V-shaped plate 321 is fixedly connected to the upper part of the outer ring surface of the first rotating circular plate 32, and a first tooth 322 is provided at the lower part of the outer ring surface of the first rotating circular plate 32, a second rotating circular plate 33 is rotatably connected to the inside of the snap shell 31 through a second fixed rod, the outer ring surface of the second rotating circular plate 33 is provided with second teeth 331, and a clamping plate 332 is fixedly connected to the lower part of the second rotating circular plate 33, one side of the clamping plate 332 abuts against a pressure plate 34, a buckle groove 341 is provided on the inner side surface of the pressure plate 34, and a first spring body 35 is fixedly connected to the outer side surface of the pressure plate 34, and one end of the first spring body 35 is fixedly connected to the inner wall of the snap shell 31.

[0036] The above scheme is adopted: as the photovoltaic panel 14 continues to rotate, the first push rods 25 on both sides of the photovoltaic panel 14 will enter the guide track 311 and continue to rotate along the guide track 311. During the rotation of the first push rod 25, the outer side of the first push rod 25 is first pressed against the inner side wall of the V-shaped plate 321, so that the V-shaped plate 321 is subjected to force transmission to the first rotating circular plate 32. The first rotating circular plate 32 is subjected to force to rotate counterclockwise on the outer side of the first fixed rod. The first rotating circular plate 32 passes through the first fixed rod. The first tooth 322 is meshed with the second tooth 331 on the second rotating circular plate 33. The second rotating circular plate 33 is rotated clockwise on the outer side of the second fixing rod under the force. The second rotating circular plate 33 drives the clamping plate 332 to rotate toward the inner side of the pressure plate 34 in the clockwise direction. As the clamping plate 332 gradually rotates clockwise, one side of the clamping plate 322 is pressed against the inner side of the pressure plate 34. After the pressure plate 34 is pressed, the pressure plate 34 is pressed to one side against the first spring body 35. As the V-shaped plate 321 continues to rotate, the clamping plate 322 is pressed against the inner side of the pressure plate 34. The V-shaped groove of the V-shaped plate 321 completely clamps the outer side of the first push rod 25 and the V-shaped plate 321 rotates to a vertical state, and then the clamping plate 332 rotates clockwise to press into the buckle groove 341. At the same time, the second push rods 26 on both sides of the photovoltaic panel 14 also rotate with the photovoltaic panel 14, so that the second push rods 26 are pressed into the push groove 271 on the push plate 27, thereby achieving the work of being fixed to the first push rod 25 and the second push rod 26, which is conducive to the setting of the V-shaped plate 321. Not only does the first resisting rod 25 get stuck inside the V-shaped plate 321, but the resisting force is also transmitted to the clamping plate 332, thereby fixing the first resisting rod 25 inside the V-shaped plate 321. By positioning the V-shaped plate 321, the photovoltaic panel 14 is permanently kept at the angle for cleaning dust, and the photovoltaic panel 14 is prevented from rotating too much. Furthermore, the photovoltaic panel 14 is effectively prevented from being unstable or shaking on both sides during cleaning, thereby improving functionality.

[0037] like Figure 5As shown, the interior of the guide track 311 guides the exterior of the first push rod 25 , and the exterior of the first push rod 25 presses against the interior of the V-shaped plate 321 .

[0038] By adopting the above solution, the V-shaped plate 321 is provided to not only allow the first push rod 25 to be stuck inside the V-shaped plate 321 , but also transmit the resisting force to the clamping plate 332 to fix the first push rod 25 inside the V-shaped plate 321 .

[0039] like Figure 5 As shown, one side of the clamping plate 332 is clamped in the clamping groove 341 .

[0040] The above solution is adopted: the V-shaped plate 321 is fixed to the outer side of the first push rod 25 by setting the clamping plate 332 and the buckling groove 341 .

[0041] like Figure 6 , Figure 7 As shown, the moving mechanism 4 includes a second electric cylinder 41 fixedly connected to a side wall of the bottom plate 21, the output end of the second electric cylinder 41 is connected to a second push rod 42, one end of the second push rod 42 is fixedly connected to a first transmission plate 43, the upper end surface of the first transmission plate 43 is fixedly connected to a tripod 44, a side surface of the tripod 44 is fixedly connected to a fixed frame plate 45, the lower end surfaces of both sides of the fixed frame plate 45 are connected to sliding blocks 451, the sliding blocks 451 are slidably matched with sliding rails 46, the lower end surface of the sliding rails 46 is connected to a bearing plate 461, one side of the bearing plate 461 is fixedly connected to a side surface of a supporting leg at the upper end of the support frame 1, a contact sensor 462 is arranged on a wall surface of one side of the sliding rail 46, a side surface of the fixed frame plate 45 is fixedly connected to a fixing frame 47, the upper part of the fixing frame 47 is fixedly connected to a fixed arc shell 471, the lower end surface of the tripod 44 is fixedly connected to a water storage tank 48, and a drainage outlet 481 is provided on one side of the outer surface of the water storage tank 48.

[0042] The above scheme is adopted: the second electric cylinder 41 drives the second push rod 42 to move to one side, the second push rod 42 is driven by the first transmission plate 43 to move to one side, the first transmission plate 43 is driven by the tripod 44 to move to one side, the tripod 44 is pulled by the fixed frame plate 45, and the fixed frame plate 45 is forced to slide through the sliding block 451 on the inside of the sliding track 46 to move to one side until one side of the sliding block 451 contacts the contact sensor 462. At this time, the contact sensor 462 receives a signal and transmits it to the controller 11. After receiving the signal, the controller 11 stops the operation of the second electric cylinder 41, and then reaches the position where the photovoltaic panel 14 is cleaned. Through the setting of the sliding track 46 and the sliding block 451, the cleaning mechanism and the moving mechanism 4 will not block the upper surface of the photovoltaic panel 14, so that the photovoltaic panel 14 can receive the maximum sunlight.

[0043] like Figure 7 As shown, the cleaning mechanism 5 includes a third electric cylinder 51 fixedly connected to the inner side of the fixed arc shell 471, the output end of the third electric cylinder 51 is connected to a third push rod 52, one end of the third push rod 52 is inserted with a guide hole 452, the guide hole 452 is opened in the middle of the fixed frame plate 45, one end of the third push rod 52 is fixedly connected to a connecting plate 53, and both sides of the connecting plate 53 are fixedly connected to a first adjusting and clamping assembly 54 and a second adjusting and clamping assembly 55.

[0044] The above scheme is adopted: after the photovoltaic panel 14 is fixed by the first support rod 25 and the second support rod 26, the third electric cylinder 51 is started to drive the third push rod 52 to move to the downward side, and the third push rod 52 is driven by the connecting plate 53. In order to ensure the stable movement of the third push rod 52, a guide hole 452 is provided, and the third push rod 52 is more stable through the guidance of the guide hole 452.

[0045] like Figure 8 As shown, the first adjusting and clamping assembly 54 includes a moving block 541 fixedly connected to one side of the connecting plate 53, the moving block 541 has a receiving groove 542 on the upper part, and a spiral hole 543 on the upper end surface of the moving block 541, the lower end of the spiral hole 543 passes through the inner upper part of the receiving groove 542, a spiral rod 544 is meshed with the inside of the spiral hole 543, a pressing hole 5441 is formed on the lower end surface of the spiral rod 544, a pressing rod 545 is pressed against the top surface of the pressing hole 5441, the upper part of the pressing rod 545 is fixedly connected to a limiting plate 546, the lower end surface of the limiting plate 546 is fixedly connected to a second spring body 5461, the lower end of the second spring body 5461 is fixedly connected to the inner bottom of the receiving groove 542, and the moving block 541 is located in the overlapping openings 453 opened on both sides of the fixed frame plate 45.

[0046] The above scheme is adopted: first adjust the height of the scraper member 5482, and manually twist the spiral rod 544 to engage with the inside of the spiral rod 544, so that the spiral rod 544 gradually moves downward, and the pressure hole 5441 on the spiral rod 544 presses against the upper end of the pressing rod 545, and the pressed rod 545 under force drives the limit plate 546 downward, and the limit plate 546 is forced to drive the second transmission plate 548 downward, and the second transmission plate 548 is forced to slide downward in the sliding hole 547. At the same time, the limit plate 546 is pressed downward on the second spring body 5461, and the second transmission plate 548 is driven downward on the tilting rod 5481, and the tilting rod 5481 is forced to drive the scraper member 5482 to move downward until the scraper member 5481 completes the contact with the upper end surface of the photovoltaic panel 14, and stops twisting the spiral rod 544 (adjustment is sufficient once), and through customized adjustment, the scraper member 5482 is better in contact with the upper surface of the photovoltaic panel 14.

[0047] like Fig. 9As shown, a sliding hole 547 is opened in the middle of the lower part of the moving block 541, and the upper end of the sliding hole 547 passes through the inner bottom of the accommodating groove 542.

[0048] The above scheme is adopted: the third push rod 52 continues to move, causing the moving block 541 and the scraper member 5482 to move to one side, and the end point of the scraper member 5482 scrapes the upper surface of the photovoltaic panel 14 that has been flushed with water. Because the photovoltaic panel 14 has been flushed with water in advance, the scraper member 5482 can more easily scrape off dust or bird droppings, which is beneficial to keep the photovoltaic panel clean and can be cleaned automatically without human intervention, thereby improving the efficiency of photovoltaic power generation and improving functionality.

[0049] The working principle and use process of the present invention:

[0050] When the photovoltaic panel 14 needs to be cleaned, first, the second electric cylinder 41 is started to drive the second push rod 42 to move to one side. The second push rod 42 is forced to drive the first transmission plate 43, the tripod 44, and the fixed frame plate 45. The fixed frame plate 45 is forced to slide on the inside of the sliding track 46 through the sliding block 451 and move to one side until one side of the sliding block 451 contacts the contact sensor 462. At this time, the contact sensor 462 receives a signal and transmits it to the controller 11. After the controller 11 receives the signal, The second electric cylinder 41 stops working, and then reaches the position where the photovoltaic panel 14 is cleaned. Then, the first electric cylinder 22 is started to drive the first push rod 23 to move upward, so that one side of the photovoltaic panel 14 is subjected to force. By rotating the sleeve 13 counterclockwise on the outside of the support rod 12, the other side of the photovoltaic panel 14 is pressed downward against the unfolding plate 24 during the rotation of the photovoltaic panel 14. The unfolding plate 24 is subjected to force and its lower part slides to one side along the sliding groove, so that the unfolding plate 24 is gradually retracted downward. As the photovoltaic panel 14 continues to rotate, The first push rods 25 on both sides of the photovoltaic panel 14 will enter the guide track 311 and continue to rotate along the guide track 311. The outer side of the first push rod 25 will first press against the inner side wall of the V-shaped plate 321. The V-shaped plate 321 is transmitted to the first rotating circular plate 32 by force. The first rotating circular plate 32 is forced to mesh with the second teeth 331 on the second rotating circular plate 33 through the first teeth 322 in a counterclockwise direction. The second rotating circular plate 33 drives the clamping plate 332 to rotate toward the inner side of the pressure plate 34 in a clockwise direction. One side of the clamping plate 322 gradually presses against the inner side of the pressure plate 34. After the pressure plate 34 is subjected to pressure, the pressure plate 34 is squeezed to one side on the first spring body 35 until the V-shaped groove of the V-shaped plate 321 completely clamps the outer side of the first push rod 25 and the V-shaped plate 321 rotates to a vertical state, and then one side of the clamping plate 332 presses against the buckle groove 341. At the same time, the second push rods 26 on both sides of the photovoltaic panel 14 are pressed against the push grooves 271 on the push plate 27, thereby achieving the work of being fixed to the first push rod 25 and the second push rod 26.

[0051] After the photovoltaic panel 14 is fixed by the first support rod 25 and the second support rod 26 (after the photovoltaic panel 14 rotates a certain angle, the controller 11 starts the water tank 48 to drain water outward through the drain port 481, so that the photovoltaic panel 14 is flushed by the water, which can effectively wash away some dust or bird droppings, until the photovoltaic panel 14 is fixed, and the water tank 48 stops draining water outward), the third electric cylinder 51 is started to drive the third push rod 52 and the connecting plate 53 to move to one side, and the third push rod 52 is more stable through the guidance of the guide hole 452.

[0052] Prior to this, the height of the scraper member 5482 is adjusted first, and the screw rod 544 and the screw rod 544 are manually twisted to make the pressure hole 5441 press against the upper end of the pressing rod 545, and the pressing rod 545 drives the limit plate 546 and the second transmission plate 548 downward, and the second transmission plate 548 is forced to slide downward inside the sliding hole 547. At the same time, the limit plate 546 is pressed downward on the second spring body 5461, and the second transmission plate 548 drives the tilting plate 548 downward. The inclined rod 5481 and the scraper member 5482 move downward until the scraper member 5481 completely contacts the upper end surface of the photovoltaic panel 14, and the screw rod 544 is stopped from being twisted. The third push rod 52 continues to move, causing the moving block 541 and the scraper member 5482 to move to one side, and the end point of the scraper member 5482 scrapes the upper surface of the photovoltaic panel 14 that has been flushed with water. Because the photovoltaic panel 14 has been flushed with water in advance, the scraper member 5482 can scrape off dust or bird droppings more easily.
