DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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. The present invention is further described below in combination with the embodiments.

[0036] See also Figure 1-5 In one embodiment of the present application, an adjustable photovoltaic panel for agricultural automated power generation includes a base 1, a support column 2, a mounting seat 5 and a plurality of photovoltaic panel bodies 6, wherein the support column 2 is movably arranged on the base 1, the mounting seat 5 is hinged to the support column 2 through a rotating shaft, and the plurality of photovoltaic panel bodies 6 are all arranged on the mounting seat 5, and further includes:

[0037] A photometric system 15, disposed on the mounting base 5, for measuring the angle of sunlight; and

[0038] The first adjustment module is arranged between the mounting seat 5 and the support column 2, and is used to adjust the angle between the support column 2 and the mounting seat 5 in real time according to the angle of the sun's rays measured by the photometric system 15;

[0039] The light measuring system 15 comprises:

[0040] A photometric box 151 is disposed on the mounting base 5, and a circular arc portion 154 is provided on the photometric box 151; and

[0041] There are several photosensitive modules evenly arranged on the light measuring box 151 . Each group of photosensitive modules extends from the arc portion 154 with a margin. The photosensitive modules are connected to the first adjustment module.

[0042] In this embodiment, each group of photosensitive modules includes a photometric tube 152, a piston 159, a light collecting glass 155, a heat collecting plate 156 and an air bag 158;

[0043] The light measuring tube 152 is arranged in the light measuring box 151 and passes through the arc portion 154 with a margin. The light collecting glass 155 and the heat collecting plate 156 are both arranged in the light measuring tube 152. The heat collecting plate 156 is located on one side of the light collecting glass 155. The piston 159 is movably arranged in the light measuring tube 152 and is connected to the No. 1 adjustment module. The piston 159 is connected to the heat collecting plate 156 through the air bag 158, and the sizes of adjacent light measuring tubes 152 change evenly.

[0044] It should be additionally explained that a heat insulating plate 157 is provided on one side of the heat collecting plate 156 , and the heat insulating plate 157 is connected to the piston 159 via an air bag 158 .

[0045] It should be noted that the heat collecting plate 156 can be made of iron, copper or aluminum, which will not be described in detail here.

[0046] In actual application, as the sun rises, the angle of the sun's rays is constantly changing, so that in different time periods, the light measuring tubes 152 at different positions on the light measuring box 151 receive sunlight. When the sunlight shines into the light measuring tube 152, the light collecting glass 155 can be used to concentrate the sunlight on the heat collecting plate 156, so that the surface of the heat collecting plate 156 is at a high temperature. By setting the heat insulating plate 157, the air bag 158 can be effectively prevented from directly contacting the heat collecting plate 156, reducing the damage to the surface of the air bag 158. In addition, under the principle of thermal expansion and contraction, the air bag 158 expands with the heat collecting plate 156. The movable piston 159 moves along the collector tube. Since the sizes of the collector tubes at different positions are different, the moving distances of the piston 159 are different. The piston 159 moves different distances according to different light irradiation angles, and the mounting seat 5 is controlled by the No. 1 adjustment module to rotate along its hinge to a corresponding angle, so that the photovoltaic panel body 6 is always vertically irradiated by sunlight. Compared with traditional fixed photovoltaic panels, this device not only has a high degree of automation and does not require manual adjustment by staff, but also can ensure that the photovoltaic panel body 6 is always in the best solar energy receiving position, thereby ensuring power generation efficiency.

[0047] See also Figure 1 , Figure 3 , Figure 4 as well as Figure 5 , as another preferred embodiment of the present application, the first adjustment module includes a telescopic element, an adjustment seat 18 and a driving arm 17;

[0048] The adjustment seat 18 is movably arranged on the support column 2, and the adjustment seat 18 is movably connected to the mounting seat 5 through the driving arm 17. The telescopic element is arranged between the adjustment seat 18 and the support column 2. The telescopic element includes a fixed end and an output end. The fixed end of the telescopic element is connected to the cavity 153 formed on the light measuring box 151, and the light measuring tube 152 is also connected to the cavity 153. The cavity 153, the light measuring tube 152 and the fixed end of the telescopic element are filled with a transmission medium.

[0049] It should be particularly noted that the telescopic element can be a cylinder 16 or a hydraulic cylinder. In the present embodiment, the telescopic element is preferably a cylinder 16, and the cylinder 16 is connected between the support column 2 and the adjustment seat 18. Correspondingly, the transmission medium is preferably gas. As for the specific composition of the gas, it is not specifically limited here.

[0050] When sunlight at different angles directly shines into the light measuring tube 152, it can drive the piston 159 to move. Since the space available for the movement of the piston 159 in the light measuring tube 152 at different positions is different, the volume of gas input into the cylinder 16 is different. The cylinder 16 telescopes and drives the adjustment seat 18 to move a corresponding distance on the support column 2 and drives the mounting seat 5 to rotate along the hinge between it and the support column 2 through the driving arm 17, thereby adjusting the angle of the photovoltaic panel 6.

[0051] See also Figure 1 as well as Figure 2 As another preferred embodiment of the present application, the photovoltaic panel further comprises a cleaning system, which is arranged between the base 1 and the mounting seat 5 and is used to clean the surface of the photovoltaic panel body 6; wherein

[0052] The cleaning system comprises:

[0053] A cleaning execution module, movably arranged on the mounting seat 5;

[0054] The second adjustment module is arranged between the support column 2 and the base 1 and connected to the cleaning execution module, and is used to adjust the position of the photovoltaic panel body 6 relative to the base 1 and the position of the cleaning execution module on the mounting seat 5.

[0055] In a specific case of this embodiment, the cleaning execution module includes a moving seat, a brush 8, a reset seat 9 and a spring 10;

[0056] The movable seat is movably arranged on the mounting seat 5 and connected to the second adjustment module, the brush 8 is slidably arranged on the surface of the photovoltaic panel body 6 and connected to the movable seat, the reset seat 9 is arranged on the mounting seat 5, the spring 10 is arranged on the reset seat 9 and its free end is connected to the movable seat, the reset seat 9 is provided with a guide groove 12, a conductive block 14 is movably arranged in the guide groove 12, and a conductive seat 13 is provided on the reset seat 9 on the moving path of the conductive block 14.

[0057] In another specific case of this embodiment, the second regulating module includes a power element, a winding disk 3 and a belt 7;

[0058] The power element is arranged on the base 1 and its power end is connected to the support column 2. The winding drum 3 is arranged on the base 1 and is connected to the moving seat through a belt 7.

[0059] It should be particularly noted that the power element can be a stepper motor or a servo motor 4. In the present embodiment, the power element is preferably a servo motor 4. The servo motor 4 is arranged on the base 1 and its power end is connected to the support column 2. As for the specific model of the servo motor 4, it can be selected according to the actual size of the photovoltaic panel 6, and no specific limitation is made here.

[0060] In actual application, the staff can control the servo motor 4 to rotate automatically every day according to the local sunshine changes, and the rotation angle corresponds to the sunshine changes. When the servo motor 4 rotates, it can drive the support column 2 to rotate and adjust the direction of the photovoltaic panel 6, so that the photovoltaic panel 6 is always opposite to the direct sunlight direction. When the support column 2 rotates, the belt 7 is automatically wound on the winding disk 3, thereby driving the moving seat and the brush 8 to move along the mounting seat 5 from one end of the photovoltaic panel 6 to the other end, thereby realizing automatic cleaning of the surface of the photovoltaic panel 6. When the brush 8 moves, the spring 10 can be used to drive the conductive block 14 to move synchronously until the conductive block 14 meets the conductive seat 13. At this time, the sun sets, and the servo motor 4 is controlled to reverse and reset, so that the brush 8 and the moving seat are automatically reset, so that not only can the photovoltaic panel 6 be exposed to the front sunlight, but also the surface of the photovoltaic panel 6 can be automatically cleaned every day without the need for manual cleaning by the staff.

[0061] How this application works:

[0062] As the sun rises, the angle of the sun's rays is constantly changing, so that in different time periods, the light measuring tubes 152 at different positions on the light measuring box 151 receive sunlight. When the sunlight shines into the light measuring tube 152, the light collecting glass 155 can be used to concentrate the sunlight on the heat collecting plate 156, so that the surface of the heat collecting plate 156 is at a high temperature. By setting the heat insulating plate 157, the air bag 158 can be effectively prevented from directly contacting the heat collecting plate 156, reducing the damage to the surface of the air bag 158. In addition, under the principle of thermal expansion and contraction, the air bag 158 expands and contracts. The expansion drives the piston 159 to move along the heat collecting tube. Since the sizes of the heat collecting tubes at different positions are different, the moving distances of the piston 159 are different. Since the spaces available for the piston 159 to move in the light measuring tubes 152 at different positions are different, the volumes of gas input into the cylinder 16 are different. The cylinder 16 is telescopically driven to drive the adjustment seat 18 to move a corresponding distance on the support column 2 and drive the mounting seat 5 to rotate along the hinge between the mounting seat 5 and the support column 2 through the driving arm 17, thereby adjusting the angle of the photovoltaic panel 6. Compared with the traditional fixed photovoltaic panel, the present invention The device not only has a high degree of automation and does not require manual adjustment by staff, but also can ensure that the photovoltaic panel body 6 is always in the best solar energy receiving position to ensure power generation efficiency. The staff can control the servo motor 4 to automatically rotate every day according to the local sunshine changes, and the rotation angle corresponds to the sunshine changes. When the servo motor 4 rotates, it can drive the support column 2 to rotate and adjust the direction of the photovoltaic panel body 6, so that the photovoltaic panel body 6 is always opposite to the direct sunlight exposure direction. When the support column 2 rotates, the belt 7 is automatically wound on the winding disk 3, thereby driving the moving seat and the brush 8 to move along the mounting seat 5 from one end of the photovoltaic panel body 6 to the other end, thereby realizing automatic cleaning of the surface of the photovoltaic panel body 6. When the brush 8 moves, the spring 10 can be used to drive the conductive block 14 to move synchronously until the conductive block 14 meets the conductive seat 13. At this time, the sun sets, and the servo motor 4 is controlled to reverse and reset, so that the brush 8 and the moving seat are automatically reset, so that not only can the photovoltaic panel body 6 be exposed to the front of the sun, but also the surface of the photovoltaic panel body 6 can be automatically cleaned every day without manual cleaning by staff.
