[0001] The present application relates to the technical field of photovoltaic support, in particular to a photovoltaic support with adjusting structure and adjusting method thereof. BACKGROUND

[0002] Solar cells, or photovoltaic cells, are a kind of power equipment that converts light energy into electrical energy through photovoltaic effect, which is a physical and chemical phenomenon, and is a form of photocell, defined as a device whose electrical properties such as current, voltage or resistance change when exposed to light. Photovoltaic panels are usually installed using photovoltaic panel installation supports during installation and construction.

[0003] Photovoltaic panels need to be erected on photovoltaic supports to receive solar radiation. Since the angle of incidence of the sun changes, the angle of the photovoltaic panel also needs to be adjusted accordingly. The existing photovoltaic panel installation supports usually have the ability to fix the photovoltaic panel or adjust its angle. Users usually manually control the angle of the photovoltaic panel according to the angle of incidence of the sun, thereby facilitating the use of the device.

[0004] However, the photovoltaic support has poor practicality when in use. Although it can adjust the angle of the photovoltaic panel to achieve better use effect, manual adjustment is required when adjusting the photovoltaic panel, which makes the photovoltaic panel unable to automatically adjust the direction of the photovoltaic panel according to the different temperatures on both sides of the photovoltaic support, thereby affecting the use effect of the device. In addition, the surface of the photovoltaic panel on the photovoltaic support may be contaminated with dust and impurities when in use, thereby affecting the use effect of the device.

[0019] Preferably, it includes the following steps:

[0020] S1. First, the tilt direction of the support plate is opposite to the position of the inflatable airbag. As the day goes by, when the sun moves to the opposite direction of the tilt direction of the support plate, the inflatable airbag is heated and expands, causing the moving plate to move. The moving plate moves the contact rod to squeeze the first switch, and the motor rotates at this time.

[0021] After the motor rotates in S2 and S1, it will drive the rotating rod to rotate. The rotation of the rotating rod will drive the first screw to rotate.

At this time, the hinge rod at the upper end of the moving sleeve moves upward, causing the bracket plate to tilt.

[0022] When the motors in S3 and S1 rotate, they drive the first rotating rod to rotate, which in turn drives the second rotating rod to rotate, which in turn drives the second screw to rotate.

[0023] Compared with the prior art, the present invention provides a photovoltaic support with an adjustable structure and its adjustment method, which has the following beneficial effects:

[0024] 1. The photovoltaic support with an adjustable structure and its adjustment method are designed to facilitate the adjustment of the tilt angle of the support plate by setting an adjustment device. When the sun moves to the opposite direction of the tilt of the support plate, the expansion bladder expands due to heat, causing the moving plate to move. The moving plate moves the contact rod to press the first switch. At this time, the motor rotates and drives the upper moving sleeve to move upward. The hinge rod at the upper end of the moving sleeve moves upward, causing the angle of the support plate to tilt. Thus, the device can automatically adjust the direction of the photovoltaic panel according to the different temperatures on both sides of the photovoltaic support.

[0025] 2. The photovoltaic bracket with an adjustable structure and its adjustment method are equipped with a cleaning device to facilitate the cleaning of the photovoltaic panels on the upper part of the bracket plate. When the motor rotates, it drives the first rotating rod to rotate, which in turn drives the second rotating rod to rotate, which in turn drives the second screw to rotate. The rotation of the second screw drives the threaded sleeve and its lower connecting rod to move left and right, thereby causing the cleaning plate at the lower end of the connecting rod to move back and forth, thus facilitating the cleaning of the photovoltaic panels without requiring the user to perform the cleaning work separately.

[0026] 3. The photovoltaic support with an adjustable structure and its adjustment method are designed with a moving groove, a compression spring, a sliding plate, and a compression rod to facilitate the adjustment of the cleaning position of the cleaning plate. The user can pull the cleaning plate upward to move it upward. At this time, the compression rod at the top of the cleaning plate moves upward to compress the compression spring and enter the moving groove, so that the cleaning plate can be moved upward to adjust its position. This allows the device to clean photovoltaic panels of different thicknesses. Attached Figure Description

Two switches 67 are compatible. A device frame 610 is provided at the lower end of the support plate 5. A bearing 611 is fixedly connected to the inner wall of the device frame 610. A first screw 612 is rotatably connected to the upper end of the bearing 611. A movable sleeve 613 is threadedly connected to the surface of the first screw 612. The upper end of the movable sleeve 613 passes through the device frame 610 and is fixedly installed with a hinge rod 614. A sliding groove is opened at the lower end of the support plate 5. The upper end of the hinge rod 614 is slidably connected inside the sliding groove. A rotating rod 615 is rotatably connected to the inner wall of the device frame 610.

A motor 618 is installed at the upper end of the support plate. The output shaft of the motor 618 is fixedly connected to the port of the rotating rod 615. A cleaning device 7 is provided on the surface of the support plate 5.

[0039] Specifically, the adjustment device 6 of the present invention includes: a support plate 61, a baffle 62, an inflatable airbag 63, a movable plate 64, a device slot 65, a first switch 66, a second switch 67, a contact rod 68, a contact plate 69, a device frame 610, a bearing 611, a first screw 612, a movable sleeve 613, a hinge rod 614, a rotating rod 615, a first bevel gear 616, a second bevel gear 617, a motor 618, and a cleaning device 7.

[0040] In one embodiment of the present invention, a support plate 61 is fixedly installed on the side wall of a long support 1. A baffle 62 is fixedly installed on the upper end of the support plate 61, and an inflatable airbag 63 is fixedly installed on the side wall of the baffle 62. A movable plate 64 is slidably connected to the surface of the support plate 61. When the inflatable airbag 63 is exposed to direct sunlight, it expands. After the inflatable airbag 63 expands, it can only push the movable plate 64, thereby causing the movable plate 64 to move. When the temperature of the inflatable airbag 63 decreases due to direct sunlight, it shrinks, thereby causing the movable plate 64 to return to its original position. A device groove 65 is provided inside the long support 1. A first switch 66 is provided on the inner wall of the device groove 65, and a second switch 67 is provided on the inner wall of the upper end of the device groove 65. The movable plate 64 is away from the baffle. A contact rod 68 is fixedly installed at one end of 62. A contact plate 69 is provided at the upper end of the contact rod 68. The contact rod 68 is located inside the device slot 65 and is adapted to the second switch 67. When the inflatable airbag 63 is heated and expands, it drives the moving plate 64 to move. After the moving plate 64 moves, it will drive the contact rod 68 on its side wall to move and squeeze the first switch 66 inside the device slot 65. When the first switch 66 is squeezed, the motor 618 rotates in the forward direction. When the moving plate 64 returns to the center, the contact plate 69 at the upper end of the contact rod 68 will squeeze the second switch 67, thereby causing the motor 618 to reverse. This facilitates the subsequent adjustment of the position of the support plate 5. A device frame 610 is provided at the lower end of the support plate 5. A bearing 611 is fixedly connected to the inner wall of the mounting frame 610. A first screw 612 is rotatably connected to the upper end of the bearing 611. A movable sleeve 613 is threaded onto the surface of the first screw 612. The upper end of the movable sleeve 613 passes through the mounting frame 610 and is fixedly mounted with a hinge rod 614. A groove is provided at the lower end of the support plate 5. The upper end of the hinge rod 614 is slidably connected inside the groove. A rotating rod 615 is rotatably connected to the inner wall of the mounting frame 610. A first bevel gear 616 is fixedly mounted at one end of the rotating rod 615, and the other end of the rotating rod 615 passes through the mounting frame 610. A second bevel gear 617 is fixedly connected to the lower surface of the first screw 612. A support plate is fixedly mounted on the side wall of the mounting frame 610. A motor 618 is mounted on the upper end of the support plate. The output shaft of motor 618 is fixedly connected to the port of rotating rod 615. When motor 618 rotates, it drives rotating rod 615, which is fixedly connected to its output shaft, to rotate. Rotating rod 615 drives first bevel gear 616 to rotate. Rotating first bevel gear 616 drives second bevel gear 617, which meshes with it, and first screw 612 inside it to rotate. Rotating first screw 612 drives the upper movable sleeve 613 to move upward. At this time, hinge rod 614 at the upper end of movable sleeve 613 moves upward, causing the angle of bracket plate 5 to tilt. This allows the device to automatically adjust the direction of photovoltaic panel according to the different temperatures on both sides of the photovoltaic bracket. Cleaning device 7 is provided on the surface of bracket plate 5.

[0041] Please continue reading.Figures 1-10The cleaning device 7 includes a cleaning frame 71, which is fixedly installed on the side wall of the support plate 5.

A connecting rod 76 is fixedly connected to the side wall of the threaded sleeve 75. A positioning plate 77 is fixedly installed at the lower end of the connecting rod 76. A cleaning plate 78 is provided at the lower end of the positioning plate 77. A rotating device 8 is provided inside the cleaning frame 71. The rotating device 8 includes a first rotating rod 81, which is rotatably connected to the inner wall of the device frame 610. A third bevel gear 82 is fixedly installed at one end of the first rotating rod 81, and the other end of the first rotating rod 81 passes through the device frame 610 and is fixedly installed with... A first pulley has a second rotating rod 83 penetrating the inner wall of a slot 72. A second pulley is fixedly mounted on the outer end of the second rotating rod 83. A synchronous belt 84 connects the first and second pulleys. A fourth bevel gear 85 is fixedly mounted on the inner end of the second rotating rod 83 within the slot 72. Two sets of second screws 74 penetrate the slot 72 and are each fixedly mounted with a fifth bevel gear 86. When the first screw 612 rotates, it drives the second bevel gear 617 on its surface to rotate. The rotation of the second bevel gear 617 drives the third bevel gear 82 meshing with it to rotate. The rotation of the third bevel gear 82 drives the first rotating rod 81 to rotate. The rotation of the first rotating rod 81 drives the first pulley to rotate, and the rotation of the first pulley drives the synchronous belt 84. The belt 84 drives the second pulley to rotate, which in turn drives the second rotating rod 83 to rotate. The rotation of the second rotating rod 83 drives the fourth bevel gear 85 fixedly connected to its surface to rotate, which in turn drives the two sets of fifth bevel gears 86 meshing with the fourth bevel gear 85 and the second screw 74 inside to rotate. The rotation of the two sets of second screws 74 drives the threaded sleeve 75 connected to its surface to move left and right. The left and right movement of the threaded sleeve 75 drives the two sets of connecting rods 76 to move, which in turn drives the cleaning plate 78 at the lower end of the two sets of connecting rods 76 to move and clean both sides of the photovoltaic panel. The support plate 61 has a sliding opening 9 inside, and a sliding rod 10 is fixedly installed on the inner wall of the sliding opening 9. The surface of the sliding rod 10 is slidably connected to a sliding plate. A return spring 12 is fixedly mounted on the surface of the sliding block 11 and the sliding rod 10. The other end of the return spring 12 is fixedly connected to the side wall of the sliding block 11. A fixed rod is fixedly mounted on the upper end of the sliding block 11. The upper end of the fixed rod is fixedly connected to the lower end of the moving plate 64. The motor 618 is electrically connected to the second switch 67 and the first switch 66. A moving groove 13 is opened on the inner wall of the lower end of the positioning plate 77. A compression spring 14 is fixedly mounted on the inner wall of the moving groove 13. A sliding plate 15 is fixedly mounted on the lower end of the compression spring 14. A compression rod 16 is fixedly mounted on the lower end of the sliding plate 15. The lower end of the compression rod 16 is fixedly connected to the upper end of the cleaning plate 78. The first bevel gear 616 and the second bevel gear 617 mesh. The contact rod 68 is located inside the device groove 65 and is adapted to the second switch 67.When a user needs to fix photovoltaic panels of different thicknesses, the user can pull the cleaning plate 78 upwards to move it upwards. At this time, the pressing rod 16 at the upper end of the cleaning plate 78 moves upwards and presses the pressing spring 14, thus entering the moving groove 13. This allows the cleaning plate 78 to move upwards and adjust its position, enabling the device to clean photovoltaic panels of different thicknesses. The surface of the cleaning frame 71 has a sliding opening that matches the moving trajectory of the connecting rod 76.

[0042] Includes the following steps:

[0043] S1. First, the tilt direction of the support plate 5 is opposite to the position of the inflatable airbag 63. As the day goes by, when the sun moves to the opposite tilt direction of the support plate 5, the inflatable airbag 63 is heated and expands, which drives the moving plate 64 to move. The movement of the moving plate 64 drives the contact rod 68 to move and squeeze the first switch 66. At this time, the motor 618 rotates.

[0044] In S2 and S1, the rotation of motor 618 will drive the rotating rod 615 to rotate. The rotation of rotating rod 615 will drive the first screw 612 to rotate. The rotation of the first screw 612 will drive the moving sleeve 613 on its surface to move upward. At this time, the hinge rod 614 at the upper end of the moving sleeve 613 moves upward, causing the angle of the support plate 5 to tilt.

[0045] When the motor 618 in S3 and S1 rotates, it drives the first rotating rod 81 to rotate, which in turn drives the second rotating rod 83 to rotate, which in turn causes the second screw 74 to rotate. The rotation of the second screw 74 drives the threaded sleeve 75 and its lower connecting rod 76 to move left and right, which causes the cleaning plate 78 at the lower end of the connecting rod 76 to move back and forth.

[0046] In an embodiment of the present invention, in order to facilitate the back-and-forth movement of the connecting rod 76, a sliding opening is provided on the surface of the cleaning frame 71 to match the movement trajectory of the connecting rod 76.

[0047] During operation, when the inflatable airbag 63 is exposed to direct sunlight, it inflates. The inflated airbag 63 can only push the moving plate 64. The moving plate 64, in turn, moves the contact rod 68 on its side wall, pressing the first switch 66 inside the device slot 65. When the first switch 66 is pressed, the motor 618 rotates in the forward direction. The rotation of the motor 618 then drives the rotating rod 615, which is fixedly connected to its output shaft, to rotate. The rotation of the rotating rod 615 drives the first bevel gear 616 to rotate. The rotation of 616 drives the second bevel gear 617 and its internal first screw 612 to rotate. The rotation of the first screw 612 drives the upper movable sleeve 613 to move upward. At this time, the hinge rod 614 at the upper end of the movable sleeve 613 moves upward, causing the bracket plate 5 to tilt. When the first screw 612 rotates, it drives the second bevel gear 617 on its surface to rotate. The rotation of the second bevel gear 617 drives the third bevel gear 82 that meshes with it to rotate. The rotation of the third bevel gear 82 drives the first screw... The first rotating rod 81 rotates, causing the first pulley to rotate. The rotation of the first pulley drives the synchronous belt 84 to rotate, which in turn drives the second pulley to rotate. The rotation of the second pulley drives the second rotating rod 83 to rotate. The rotation of the second rotating rod 83 drives the fourth bevel gear 85 fixedly connected to its surface to rotate, which in turn drives the two sets of fifth bevel gears 86 meshing with the fourth bevel gear 85 and the second screw 74 inside them to rotate. The rotation of the two sets of second screws 74 in turn drives the threaded sleeve 75 threadedly connected to its surface to move left and right. The left and right movement of the 5-axis causes the two sets of connecting rods 76 to move, which in turn causes the cleaning plates 78 at the lower end of the two sets of connecting rods 76 to move and clean both sides of the photovoltaic panel. When the expansion airbag 63 is exposed to direct sunlight and the temperature decreases, it will shrink, causing the moving plate 64 to return to its original position. When the moving plate 64 returns to its original position, the contact plate 69 at the upper end of the contact rod 68 will press the second switch 67, causing the motor 618 to reverse and adjust the bracket plate 5 back to its original position, thus facilitating subsequent adjustment of the position of the bracket plate 5.

[0048] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.

10. A method for adjusting a photovoltaic support with an adjustable structure according to claims 1-9, characterized in that: Includes the following steps: S1. First, the tilt direction of the support plate (5) is opposite to the position of the inflatable airbag (63). As the day progresses, when the sun moves to the opposite tilt direction of the support plate (5), the inflatable airbag (63) expands due to heat, causing the moving plate (64) to move. The moving plate (64) moves, causing the contact rod (68) to move and press the first switch (66). At this time, the motor (618) rotates. After the motor (618) in S2 and S1 rotates, it will drive the rotating rod (615) to rotate. The rotation of the rotating rod (615) will drive the first screw (612) to rotate. The rotation of the first screw (612) will drive the moving sleeve (613) on its surface to move upward. At this time, the hinge rod (614) at the upper end of the moving sleeve (613) moves upward, causing the angle of the support plate (5) to tilt. When the motor (618) in S3 and S1 rotates, it will drive the first rotating rod (81) to rotate, thereby driving the second rotating rod (83) to rotate, which in turn causes the second screw (74) to rotate. The rotation of the second screw (74) drives the threaded sleeve (75) and its lower connecting rod (76) to move left and right, thereby causing the cleaning plate (78) at the lower end of the connecting rod (76) to move back and forth.
