[0033] Example:

[0034] Reference Figure 1-Figure 7 An adjustable photovoltaic power generation device includes a mounting base plate 3 and a flippable solar panel connected to the mounting base plate 3, wherein the solar panel includes a first photovoltaic panel 1 and two groups of second photovoltaic panels 2, and the second photovoltaic panels 2 are symmetrically slidably connected to the first photovoltaic panel 1.

[0035] In this embodiment, a flippable solar panel is provided on the mounting base plate 3. At the same time, two groups of second photovoltaic panels 2 which can be slidably connected to the first photovoltaic panel 1 are provided. The second photovoltaic panels 2 can be flipped according to the angle of sunlight exposure, thereby ensuring sufficient exposure time and area as much as possible, improving the utilization rate of the photovoltaic power generation device, and expanding the area of ​​the entire solar panel for easy storage, disassembly and transportation.

[0036] A flip assembly, the flip assembly includes a diagonal brace 7 pinned between the solar cell panel and the mounting base plate 3;

[0037] Specifically, two groups of diagonal braces 7 are symmetrically arranged between the first photovoltaic panel 1 and the mounting base plate 3, and the inclination angle of the diagonal braces 7 is controlled to change the angle between the first photovoltaic panel 1 and the mounting base plate 3, thereby achieving the angle adjustment function of the solar cell panel.

[0038] It should be noted that, in this embodiment, a photoresistor type measuring instrument is used to monitor the sunshine angle, and the preferred model is: ZH6674. Its specific operation is that the photoresistor type measuring instrument utilizes the characteristic that the resistance of the photoresistor changes with the light intensity, uses the photoresistor as a measuring element, outputs an electrical signal to measure the light intensity, and thus calculates the sunshine angle.

[0039] The driving assembly includes a screw rod 5, one end of a diagonal support 7 is slidably arranged on the surface of the screw rod 5, the screw rod 5 is rotatably installed on the mounting base plate 3, and one end of the screw rod 5 is transmission-connected to a motor 41, one side of the moving block 6 is connected to a driving block 19, an internal threaded sleeve 20 is rotatably connected inside the driving block 19, and the internal threaded sleeve 20 and the screw rod 5 are threadedly connected.

[0040] In this embodiment, after the photoresistance measuring instrument converts data through PLC, the electrical signal is connected to the motor 41, thereby controlling the solar cell panel to flip.

[0041] Specifically, the motor 41 is started to drive the screw 5 to rotate, and the screw 5 drives the internal threaded sleeve 20 on its surface. The internal threaded sleeve 20 is rotatably connected to the driving block 19 through a bearing, so that the driving block 19 can slide on the surface of the screw 5.

[0042] Second pin-connected supports 9 are provided at the four corners of the bottom surface of the first photovoltaic panel 1, a moving block 6 is slidably provided in the mounting base plate 3, the diagonal support 7 is pinned between the moving block 6 and the second pin-connected support 9 through the first pin-connected support 8, the moving block 6 and the screw 5 are slidably connected, and two groups of legs 4 are symmetrically provided on the mounting base plate 3, and the top of the legs 4 are pinned to the bottom surface of the first photovoltaic panel 1 through the second pin-connected support 9.

[0043] In this embodiment, a moving block 6 is connected to one side of the driving block 19, and a diagonal brace 7 is pinned between the moving block 6 and the second pin-connected support 9. The moving block 6 moves in the mounting base plate 3, driving one end of the diagonal brace 7 to move on the mounting base plate 3. Since one side of the first photovoltaic panel 1 is pinned to the top of the mounting base plate 3 through the support leg 4 and the second pin-connected support 9 on the other side is pinned to the diagonal brace 7, the first photovoltaic panel 1 uses the pinned position at the top of the support leg 4 as the fulcrum, and changes the position of one end of the diagonal brace 7 by moving the moving block 6, thereby changing the angle between the diagonal brace 7 and the mounting base plate 3, thereby realizing the flipping of the first photovoltaic panel 1.

[0044] A spacing adjustment component is connected between the two groups of second photovoltaic panels 2, and the spacing adjustment component includes an adjustment sleeve 24, in which a left-hand screw rod 25 and a right-hand screw rod 26 are symmetrically threaded, and one end of the left-hand screw rod 25 and the right-hand screw rod 26 are respectively rotatably connected to the two groups of second photovoltaic panels 2.

[0045] In the present embodiment, a spacing adjustment component is provided between the two groups of second photovoltaic panels 2. Specifically, an adjustment sleeve 24, a left-hand screw 25 and a right-hand screw 26 are sequentially provided between the two groups of second photovoltaic panels 2. Since one end of the left-hand screw 25 and the right-hand screw 26 are rotatably connected to one side of the second photovoltaic panel 2, when the adjustment sleeve 24 rotates forward / reverse, it can push the two groups of second photovoltaic panels 2 closer or apart, thereby changing the area of ​​the solar cell panel.

[0046] It should be noted that guide strips are symmetrically arranged on the inner side of the first photovoltaic panel 1, and notches matching the guide strips are opened on both sides of the second photovoltaic panel 2 to ensure the structural stability of the second photovoltaic panel 2 during movement;

[0047] A through groove is provided at the bottom of the first photovoltaic panel 1 to provide space for the meshing of the first bevel gear 22 and the second bevel gear 23 without affecting the normal operation of the photovoltaic panel.

[0048] A rack 18 is connected to one side of the driving block 19, and a driving wheel 17 is meshed with one side of the rack 18. A support rod 16 is rotatably connected to the mounting base plate 3, and the driving wheel 17 is fixedly mounted on the bottom end of the support rod 16. A hollow tube 15 is slidably connected to the top of the support rod 16, a spring 21 is arranged in the hollow tube 15, a first bevel gear 22 is fixedly mounted on the top of the hollow tube 15, and a second bevel gear 23 is fixedly mounted on the surface of the adjustment sleeve 24, and the first bevel gear 22 and the second bevel gear 23 are meshed.

[0049] In this embodiment, a rack 18 is installed on one side of the driving block 19, and a support rod 16 is rotatably installed on the mounting base plate 3. The bottom end of the support rod 16 is fixedly connected to a driving wheel 17. During the movement of the driving block 19, the rack 18 can be driven to move. The movement of the rack 18 drives the driving wheel 17 to rotate. The rotation of the driving wheel 17 drives the support rod 16 to rotate. The top of the support rod 16 is keyed and slidably inserted into the hollow tube 15. The top of the hollow tube 15 and the surface of the adjusting sleeve 24 are respectively provided with a meshing first bevel gear 22 and a second bevel gear 23. Therefore, the diagonal support 7 can expand the area of ​​the first photovoltaic panel 1 while adjusting the angle of the first photovoltaic panel 1, and improve the efficiency of the lighting effect as much as possible during the tilting effect.

[0050] It should be noted that the key connection between the hollow tube 15 and the support rod 16 can not only ensure the sliding connection between the hollow tube 15 and the support rod 16, but also the rotation of the support rod 16 can drive the first bevel gear 22 at the top of the hollow tube 15 to rotate. The setting of the spring 21 ensures that when the first photovoltaic panel 1 and the second photovoltaic panel 2 are flipped, the first bevel gear 22 and the second bevel gear 23 always maintain contact within the flipping angle range of the first photovoltaic panel 1 and the second photovoltaic panel 2.

[0051] A spray assembly is arranged on one side of the installation base plate 3, and the spray assembly includes a water tank 12 and a water pipe 10 connected to the top of the water tank 12, a valve 11 is arranged in the water pipe 10, and the top of the water pipe 10 is connected to a spray chamber 13, the spray chamber 13 is connected to a high-pressure spray nozzle 14 on the side close to the first photovoltaic panel 1, and a photoelectric control switch 40 is arranged at the bottom of the spray chamber 13, and the photoelectric control switch 40 and the valve 11 are electrically connected.

[0052] In this embodiment, a group of spray components is arranged on one side of the solar power generation panel. When the first photovoltaic panel 1 is in a tilted state, the valve 11 in the water pipe 10 is triggered by the photoelectric control switch 40 to spray the first photovoltaic panel 1 and the second photovoltaic panel 2 to flush their surfaces and remove dust in time.

[0053] Specifically, the water tank 12 is connected to an external water pump. When the solar panel is flipped to the extreme position, the unfolded second photovoltaic panel 2 triggers the photoelectric control switch 40. The photoelectric control switch 40 starts the valve 11 and the external water pump. The water in the water tank 12 flushes the first photovoltaic panel 1 and the second photovoltaic panel 2 through the high-pressure spray nozzle 14.

[0054] It should be noted that when the spray assembly is turned on when the solar panel is tilted, the water flow can quickly and smoothly remove the dust in a timely manner.

[0055] In addition, the high-pressure spray nozzles 14 located on both sides of the spray chamber 13 are connected by a universal self-sealing pipe joint. The spray direction of the high-pressure spray nozzles 14 is adjusted according to the area of ​​the first photovoltaic panel 1 and the second photovoltaic panel 2, so as to flush the surface of the first photovoltaic panel 1 and the second photovoltaic panel 2 as comprehensively as possible.

[0056] The cleaning assembly includes a bellows 27 and a column 31 pinned to one end of the bellows 27 , and one end of the column 31 is rotatably connected to the mounting base plate 3 .

[0057] A first ear plate 30 is fixedly connected to the top of the column 31 . The first ear plate 30 is pin-connected to one end of the bellows 27 . A fan 29 is connected to one side of the bellows 27 . A cleaning brush roller 28 is rotatably installed in the bellows 27 .

[0058] In this embodiment, a bellows 27 is provided above the installation base plate 3 and away from the side of the water tank 12. The bellows 27 is initially on one side of the first photovoltaic panel 1 and the second photovoltaic panel 2. As the first photovoltaic panel 1 and the second photovoltaic panel 2 are flipped, the bellows 27 is synchronously flipped to blow and clean the solar panels.

[0059] Specifically, when the motor 41 is started, the fan 29 is also started, and the column 31 rotates along with the flipping of the solar panel.

[0060] A third ear plate 34 is fixedly connected to one side of the bottom of the bellows 27 , a second ear plate 33 is fixedly installed on the surface of the column 31 , and a tension spring 32 is connected between the second ear plate 33 and the third ear plate 34 .

[0061] In this embodiment, the bellows 27 and the column 31 are pinned by the second ear plate 33, which can ensure that during the flipping of the first photovoltaic panel 1, the bellows 27 is always in close contact with the first photovoltaic panel 1 and the second photovoltaic panel 2 by the tension of the tension spring 32. The bellows 27 is hollow, and the fan 29 blows air and removes dust through the bellows 27 via the installation position of the cleaning brush roller 28.

[0063] In this embodiment, a drive shaft 35 is transmission-connected at one end of the screw rod 5, a third bevel gear 36 is arranged on the surface of the drive shaft 35, the column 31 is rotationally connected to the mounting base plate 3 through a bracket 37, a fifth bevel gear 39 is fixedly connected to the bottom end of the column 31, two sets of symmetrically arranged fourth bevel gears 38 are arranged between the third bevel gear 36 and the fifth bevel gear 39, the two sets of fourth bevel gears 38 rotate synchronously, so that the third bevel gear 36 and the fifth bevel gear 39 are meshed and transmitted, so that during the flipping process of the first photovoltaic panel 1 and the second photovoltaic panel 2, the bellows 27 is driven to rotate around the column 31, the surfaces of the first photovoltaic panel 1 and the second photovoltaic panel 2 are cleaned and blown, and the floating dust on the surface and the dust swept by the brush roller 28 are sucked away.

[0064] In the present invention, a photoresistor type measuring instrument is installed on the mounting base plate 3. According to the data transmitted to the PLC by the photoresistor type measuring instrument, the motor 41 and the fan 29 are started simultaneously according to the environmental requirements after conversion:

[0065] Start the motor 41 to drive the screw 5 to rotate. The screw 5 drives the internal threaded sleeve 20 on its surface. The internal threaded sleeve 20 is rotatably connected to the driving block 19 through the bearing. A moving block 6 is connected to one side of the driving block 19. The moving block 6 moves in the mounting base plate 3. A diagonal brace 7 is pinned between the moving block 6 and the second pin-connected support 9, driving one end of the diagonal brace 7 to move on the mounting base plate 3. Since one side of the first photovoltaic panel 1 is pinned to the top of the mounting base plate 3 through the support leg 4 and the second pin-connected support 9, and the second pin-connected support 9 on the other side is pinned to the diagonal brace 7, the first photovoltaic panel 1 uses the pinned position at the top of the support leg 4 as the fulcrum. The position of one end of the diagonal brace 7 is changed by moving the moving block 6, thereby changing the angle between the diagonal brace 7 and the mounting base plate 3, driving the first photovoltaic panel 1 to flip.

[0066] At the same time, during the movement of the driving block 19, the rack 18 can be driven to move, and the movement of the rack 18 drives the driving wheel 17 to rotate, and the rotation of the driving wheel 17 drives the support rod 16 to rotate, and the top key of the support rod 16 is connected and slidably inserted into the hollow tube 15, and the first bevel gear 22 at the top of the hollow tube 15 drives the second bevel gear 23 to rotate, thereby driving the adjustment sleeve 24 to rotate, pushing the left-hand screw rod 25 and the right-hand screw rod 26 to drive the two groups of second photovoltaic panels 2 to move toward the outside of the first photovoltaic panel 1, thereby expanding the area of ​​the first photovoltaic panel 1;

[0067] When the motor 41 is started, the fan 29 is also started, and the column 31 rotates along with the flipping of the solar panel. During the flipping of the first photovoltaic panel 1 and the second photovoltaic panel 2, the wind box 27 is driven to rotate around the column 31 to clean and blow air to the surfaces of the first photovoltaic panel 1 and the second photovoltaic panel 2, and to remove the floating dust on the surface and the dust cleaned by the cleaning roller 28;

[0068] At the same time, the external water pump is started. When the solar panel is flipped to the extreme position, the unfolded second photovoltaic panel 2 triggers the photoelectric control switch 40. The photoelectric control switch 40 starts the valve 11 and the external water pump. The water in the water tank 12 is flushed to the first photovoltaic panel 1 and the second photovoltaic panel 2 through the high-pressure spray nozzle 14. The spray component is turned on when the solar panel is tilted. The water flow can quickly and smoothly remove the dust in time, ultimately ensuring that the surface of the first photovoltaic panel 1 and the second photovoltaic panel 2 is clean, effectively ensuring the working efficiency of the photovoltaic power generation device.

[0069] It should be noted that the working principle and electrical connection of the solar photovoltaic panel are well known and will not be described in detail in this embodiment.
