[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] A solar panel with adjustable lighting angle, such as Figures 1 to 5 As shown, it includes a base plate 100, a vertical shaft 140 is rotatably provided at the center position of the top of the base plate 100, a substrate 130 is fixedly sleeved on the outer wall of the vertical shaft 140, a photovoltaic panel 110 is rotatably installed on the substrate 130, a driven disk 141 is fixed at the top of the vertical shaft 140, a plurality of groups of paddles 142 are fixed at the top edge position of the driven disk 141, a cleaning plate 120 is fixed at the top of the base plate 100 near the left side, a mounting groove 123 is provided at the bottom end of the cleaning plate 120, two groups of brush strips 121 are horizontally slidably provided in the mounting groove 123, a force strip 124 is longitudinally slidably provided at one side of the end of the brush strip 121 in the mounting groove 123, and a force rod 126 extending to the bottom of the cleaning plate 120 is fixed at the bottom end of the force strip 124;

[0024] A first spring 122 fixed to the inner wall of the mounting groove 123 is disposed at one end of the brush strip 121 away from the stress strip 124, and a first hemispherical body 127 is fixed to one end of the brush strip 121 close to the stress strip 124;

[0025] Both ends of the stress bar 124 are provided with second springs 125 fixed to the inner wall of the mounting groove 123 . A plurality of groups of second hemispheres 128 are fixed to one side of the stress bar 124 close to the brush bar 121 , and a certain distance exists between every two groups of second hemispheres 128 .

[0026] When the vertical shaft 140 rotates, the fixed base plate 130 of the outer wall rotates accordingly, so that the photovoltaic panel 110 can always be aligned with the sun to achieve a better sunlight absorption effect;

[0027] The ring piece 102 is fixedly connected to the base rod 131, so it can move along the ring groove 101 in a circular track, and can prevent dust from entering to cause additional resistance, which can reduce the additional load on the driving device in the device and further increase its service life;

[0028] When the photovoltaic panel 110 is about to rotate and pass under the cleaning plate 120 as the substrate 130 rotates, the remote terminal will control the photovoltaic panel 110 to be lowered to the lowest state (control the telescopic end of the electric push rod 150 to shorten). At this time, the photovoltaic panel 110 will pass under the cleaning plate 120 as the substrate 130 rotates, and then the dust on the surface of the photovoltaic panel 110 is cleaned by the brush strip 121. When the photovoltaic panel 110 passes under the cleaning plate 120, the paddle 142 on the top of the vertical shaft 140 will continue to contact the force bar 126, which will push the force bar 124 to move, and the second hemisphere 128 on one side Contact with the first hemisphere 127 will squeeze the brush strip 121 to move laterally and compress the first spring 122. When the paddle 142 is separated from the force-bearing rod 126, the second spring 125 will restore the force-bearing strip 124, and the second hemisphere 128 will be separated from the first hemisphere 127. Under the action of the first spring 122, the brush strip 121 will continue to shake laterally, so that the dust attached to the brush strip 121 will fall off. Because there are multiple paddles 142, the brush strip 121 can be shaken multiple times, so that the residual dust will fall off when it cleans the photovoltaic panel 110, ensuring that the photovoltaic panel 110 is cleaned more efficiently next time.

[0029] Please refer to Figure 2 and Figure 4 The top of the base 100 is located on the outer wall of the vertical shaft 140, and a shell is connected to it through a bearing sleeve. A motor 160 is installed in the shell at the top of the base 100. The output end of the motor 160 is connected to a worm 161. The outer wall of the vertical shaft 140 is fixed with a worm wheel 143 that is meshed with the worm 161.

[0030] The housing is used to protect the motor 160, the worm 161 and the worm wheel 143 to prevent foreign objects from winding around them and affecting their normal transmission.

[0031] Please refer to Figure 2 and Figure 3The bottom end of the base plate 130 is provided with a base rod 131 extending into the base plate 100, and an annular groove 101 is opened at the contact position between the top of the base plate 100 and the base rod 131. The outer wall of the base rod 131 is sleeved with an annular piece 102 movably arranged in the annular groove 101, and the annular piece 102 is arranged in the annular groove 101 for fixed point rotation.

[0032] A hidden groove is provided at the center of the top of the substrate 130, in which an electric push rod 150 is installed. The output end of the electric push rod 150 is fixedly slidably arranged on a driven seat 151 in the hidden groove. A support arm 111 is rotatably provided on the top of the driven seat 151 and is rotatably connected to the bottom end of the photovoltaic panel 110. The bottom end of the support arm 111 on one side away from the support arm 111 is rotatably arranged with the top of the substrate 130.

[0033] The telescopic end of the electric push rod 150 pulls the driven seat 151 to move, thereby changing the bottom position of the support arm 111, so that the photovoltaic panel 110 rotates around the rotation point with the substrate 130, thereby changing the angle at which the photovoltaic panel 110 is set, and can better receive sunlight. The base rod 131 constrains the substrate 130 to make it move in a circular trajectory along the annular groove 101, so that the substrate 130 can achieve a rotation effect, so that the photovoltaic panel 110 is always aimed at the sun to achieve a better absorption rate.

[0034] When in use, when the vertical shaft 140 rotates, the fixed base plate 130 of the outer wall rotates accordingly, so that the photovoltaic panel 110 can always be aligned with the sun, achieving a better sunlight absorption effect;

[0035] The ring piece 102 is fixedly connected to the base rod 131, so it can move along the ring groove 101 in a circular track, and can prevent dust from entering to cause additional resistance, which can reduce the additional load on the driving device in the device and further increase its service life;

[0036] When the photovoltaic panel 110 is about to rotate and pass under the cleaning plate 120 as the substrate 130 is about to rotate, the remote terminal will control the photovoltaic panel 110 to be lowered to the lowest state (control the telescopic end of the electric push rod 150 to shorten). At this time, the photovoltaic panel 110 will pass under the cleaning plate 120 as the substrate 130 rotates, and then the dust on the surface of the photovoltaic panel 110 is cleaned by the brush strip 121. When the photovoltaic panel 110 passes under the cleaning plate 120, the paddle 142 on the top of the vertical shaft 140 will continue to contact the force rod 126, which will push the force bar 124 to move, and the second hemisphere 128 on one side will contact the first hemisphere 127, which will squeeze The brush strip 121 moves laterally and compresses the first spring 122. When the paddle 142 is separated from the force-bearing rod 126, the second spring 125 will restore the force-bearing strip 124, and the second hemisphere 128 will be separated from the first hemisphere 127. Under the action of the first spring 122, the brush strip 121 will continue to shake laterally, so that the dust attached to the brush strip 121 will fall off. Because there are multiple paddles 142, the brush strip 121 can be shaken multiple times to make the residual dust fall off when it cleans the photovoltaic panel 110, ensuring that the photovoltaic panel 110 is cleaned more efficiently next time. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
