[0020] Reference Figures 1 to 5 As shown, the present invention provides an automatic dust shielding protective cover for photovoltaic panels at night, comprising: a protective cover body 1, the protective cover body 1 comprises a first cover 11 and a second cover 12, and the first cover 11 and the second cover 12 are symmetrically mounted on the outer side of a mounting plate 5 on the lower side of a photovoltaic panel 6, respectively, and a support rod is connected to the lower side of the mounting plate 5, and a control box 3 is mounted on the outer side of the support rod, and a light sensor 4 is mounted on the outer wall of the control box 3, a pull-out plate 111 is slidably connected to one side of the first cover 11, and a plug-in slot 121 is provided at the opposite end of the second cover 12 and the first cover 11, a driving assembly 2 is arranged on the outer side of the mounting plate 5, and the driving assembly 2 comprises a dual-axis motor 20, and driving shafts 21 are connected to both ends of the dual-axis motor 20.

[0021] In this embodiment, the protective cover body 1 and the driving assembly 2 constitute the main structure of the photovoltaic panel nighttime automatic dust shielding protective cover involved in this application.

[0022] Specifically, when the first cover 11 and the second cover 12 are flipped to the same horizontal plane, there is a gap space between the first cover 11 and the second cover 12. Secondly, the lower end of the first cover 11 is connected to the drive shaft 21. When the connected part is closed, it shields and protects the outer side of the photovoltaic panel 6. At the same time, the connection method between the second cover 12 and the transmission rod involved below is consistent with that of the first cover 11 and the drive shaft 21.

[0023] Specifically, the mounting plate 5 is rotatably connected to the support rod at the lower side to achieve angle adjustment of the photovoltaic panel 6 .

[0024] As a preferred implementation, the light sensor 4 senses the brightness of the light in the external environment, so that the drive component 2 can be automatically started at night.

[0025] like Figure 2 , Figure 3 and Figure 4 In the figure, the first cover 11 and the second cover 12 are both set to an L-shaped structure, and a guide groove 114 is opened on the upper side of the first cover 11, and a connecting block 113 is slidably connected in the guide groove 114, an electric push rod 112 is installed on the upper side of the first cover 11, and the piston rod end of the electric push rod 112 is connected to the connecting block 113, and the inner end of the connecting block 113 is connected to the pull-out plate 111, and the pull-out plate 111 includes a horizontal plate slidably inserted in the first cover 11, and vertical plates are connected at both ends of the lower side of the horizontal plate, and the vertical plates are slidably connected to the lower side of the first cover 11.

[0026] Specifically, a groove cavity identical to the insertion groove 121 is formed inside the first cover 11 , and the groove cavity is communicated with the guide groove 114 , so that the pull-out plate 111 can be easily stored.

[0027] Specifically, when the pull-out plate 111 is plugged into the plug-in slot 121, the outer ends of the two vertical plates, i.e., the side close to the drive shaft 21, are connected with elastic cloth, so that when the pull-out plate 111 is inserted into the plug-in slot 121, the vertical plate moves to the lower side of the second cover 12 and the head is flush with the photovoltaic panel 6 on this side. At this time, the elastic cloth is stretched to achieve dust protection for the side of the photovoltaic panel 6 on the lower side of the first cover 11.

[0028] like Figure 1 , Figure 2 and Figure 5 In the embodiment, the outer end of the driving shaft 21 is connected to the first gear 23, and the rear side of the first gear 23 is meshed with the second gear 24, and the second gear 24 is fixed to the side wall of the mounting plate 5, and a pulley 25 coaxially connected thereto is provided on the outer side of the second gear 24, the lower end of the second cover 12 is connected to a transmission rod, and the transmission rod is rotatably connected to the outer side of the mounting plate 5, and the outer end of the transmission rod is connected to the pulley 25, and the pulley 25 is connected to the pulley 25 on the outer side of the second gear 24 through a belt 26 transmission connection, the plug-in slot 121 is matched and plugged with the pull-out plate 111, and when the pull-out plate 111 is plugged with the plug-in slot 121, the vertical plates on both sides of the pull-out plate 111 are located on the outer side of the photovoltaic panel 6, and the outer sides of the driving shaft 21 and the transmission rod are rotatably connected with the shaft sleeve 22, and the shaft sleeve 22 is fixed to the outer wall of the mounting plate 5.

[0029] As a preferred embodiment, by providing the first gear 23 and the second gear 24 , the drive shaft 21 and the transmission rod can be synchronously rotated in opposite directions through the pulley 25 and the belt 26 , thereby achieving the opening and closing effect of the protective cover body 1 .

[0030] During use, during the day, the first cover and the second cover are in an open state, and the pull-out plate is retracted into the first cover by the electric push rod. At this time, the first cover and the second cover are both on the outside of the photovoltaic panel, and will not block the sunlight on the upper side of the photovoltaic panel, thereby ensuring the light energy utilization rate of the photovoltaic panel during the day; at night, through the sensing of the external environment by the photosensitive sensor, the dual-axis motor is started by the control box, and then connected to the lower end of the first cover through the drive shaft, and through the first gear, the second gear and the pulley and the belt, the drive transmission rod is connected to the lower end of the second cover, and then the first cover and the second cover are driven to rotate close to each other at the same time. When they are in the same horizontal plane, the electric push rod is started to push the pull-out plate out and plug it into the plug-in slot of the second cover, thereby achieving a dust-proof effect on the photovoltaic panel at night.

[0031] The automatic nighttime dust shielding protective cover for photovoltaic panels of the present invention can effectively solve the problems that existing solar photovoltaic panel protective covers affect the utilization rate of solar energy and are too large to be stored. It is based on the existing technology of automatic nighttime dust shielding protective covers for photovoltaic panels and can automatically achieve dust-proof protection for photovoltaic panels at night, while opening it during the day can ensure the utilization rate of solar energy.
