Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel components, in particular to a solar photovoltaic panel component with a self-cleaning function. Background Art

[0002] Solar photovoltaic panels are a device that converts solar energy into electrical energy, which is renewable, clean and environmentally friendly. Its working principle is based on the photoelectric effect, which is the ability of energy to be converted into electrons when light shines on the surface of a specific material. Publication (Announcement) No.: CN220822977U discloses an adjustable solar photovoltaic panel assembly, which is applied in the field of photovoltaic panel assemblies. The utility model has connecting plates fixedly installed on both sides of the top of the base, and a side plate fixedly installed on one side of the connecting plate, and a photovoltaic panel body fixedly installed between the two side plates. When the adjustable solar photovoltaic panel assembly is used, the setting of the connecting plate and the side plate is convenient for installing the photovoltaic panel body on the top of the base, and then the connection between the connecting plate and the base is increased through the connection of bolts and nuts, and then the cover body 1 is preferentially connected and installed with the connecting groove 1, and then the cover body 2 is connected and installed with the connecting groove 2. In the rainy season, when rainwater enters the connecting groove 1, the guide groove can guide the rainwater outward to prevent the rainwater from causing rust to it. At the same time, the rubber ring 1 and the rubber ring 2 increase its sealing performance to prevent the bolts and nuts from being exposed to rain for a long time and causing rust, thereby reducing the inconvenience of later disassembly and maintenance.

[0003] The above-mentioned prior art solutions have the following defects: since the photovoltaic panel body is in an open environment for a long time, the light absorbing surface of the photovoltaic panel body is prone to adhere to a lot of impurities such as dust and bird droppings. Since the adhesion of dust and bird droppings is strong, rain cannot wash them clean. Dust and bird droppings easily block sunlight, thereby reducing the efficiency of converting solar energy into electrical energy. The existing solar photovoltaic panel assemblies do not have a self-cleaning function, and workers are required to climb to a high place to clean impurities, which increases labor intensity and reduces the convenience of maintenance. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a solar photovoltaic panel assembly with a self-cleaning function. A large amount of rainwater is drained to the upper inclined surface of the photovoltaic panel body through a rainwater guiding assembly. The rotating brush roller and the flowing rainwater cooperate to clean the impurities on the inclined surface of the photovoltaic panel body, thereby improving the convenience of maintenance.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a solar photovoltaic panel assembly with a self-cleaning function, comprising: an inclined fixing frame and a photovoltaic panel body connected to the upper end thereof, wherein the front and rear sides of the photovoltaic panel body are respectively connected with guide rail assemblies, and a brush roller assembly connected to the light absorbing surface of the photovoltaic panel body in a rolling manner is connected between the guide rail assemblies; further comprising a rainwater guide assembly and a linear driving mechanism for driving the brush roller assembly to reciprocate along the inclined direction, wherein the rainwater guide assembly is connected to the inclined upper end of the photovoltaic panel body and is suitable for guiding rainwater to fall on the inclined upper end of the light absorbing surface of the photovoltaic panel body;

[0007] By adopting the above technical solution, in rainy weather, more rainwater is guided by the rainwater guiding assembly to fall on the inclined upper end of the light absorbing surface of the photovoltaic panel body, and the rainwater flows downward along the light absorbing surface of the photovoltaic panel body. The rotary drive device drives the brush roller to rotate, and at the same time, the linear drive mechanism drives the brush roller on the brush roller assembly to move back and forth along the light absorbing surface of the photovoltaic panel body. Under the interaction of rainwater and the rotating brush roller, impurities on the light absorbing surface of the photovoltaic panel body are cleaned, and workers do not need to climb to a high place to clean impurities, which reduces the labor intensity of workers and improves the convenience of maintenance.

[0008] In a preferred example, the utility model can be further configured as follows: the guide rail assembly includes an inclined plate and a guide rail connected to the upper surface thereof, a movable plate is connected to the slider of the guide rail, and the movable plate is connected to a corresponding mounting seat.

[0009] By adopting the above technical solution, the movable plate on the guide rail is driven to move in an inclined direction under the action of an external force, that is, the brush roller assembly performs an inclined reciprocating movement along the light absorbing surface of the photovoltaic panel body.

[0011] By adopting the above technical solution, the rotary drive assembly works by driving the movable plate on the guide rail assembly to move through the screw assembly, and the movable plate drives the brush roller assembly to move linearly.

[0012] In a preferred example, the utility model can be further configured as follows: the screw assembly includes a screw body and support seats rotatably connected to both ends thereof, a nut seat spirally connected to the screw body is provided between the support seats, and the nut seat is connected to the movable plate.

[0013] By adopting the above technical solution, the rotary drive assembly drives the screw body to rotate, and the screw body drives the moving plate on the guide rail assembly to move through the nut seat.

[0014] In a preferred example, the utility model can be further configured as follows: the rotation drive assembly includes a fixed plate and a dual-output shaft motor connected to the upper surface thereof, the two sides of the dual-output shaft motor are respectively connected to transmission shafts, the transmission shaft includes a transmission shaft and a coupling, one end of the transmission shaft is connected to the output shaft of the dual-output shaft motor through a coupling, and the other end is sleeved with an active bevel gear, the oblique upper end of the screw rod body is sleeved with a driven bevel gear, the driven bevel gear is meshed with the active bevel gear, the end of the transmission shaft close to the active bevel gear is rotatably connected to an inclined fixing seat, and the inclined fixing seat is connected to the oblique upper end of the photovoltaic panel body.

[0015] By adopting the above technical solution, the dual-output shaft motor drives the transmission shafts on both sides to rotate, the transmission shaft drives the active bevel gear to rotate, the active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the screw body to rotate, that is, the screw body drives the moving plate on the guide rail assembly to move through the nut seat.

[0017] By adopting the above technical scheme, rainwater falling on the inclined guide plate flows obliquely downward, and falls on the oblique upper end of the light absorbing surface of the photovoltaic panel body after passing through the water flow cavity. Rainwater falling on the inclined surface of the V-shaped protective plate flows through the water flow cavity and falls on the oblique upper end of the light absorbing surface of the photovoltaic panel body, so that more rainwater flows from the oblique upper end of the light absorbing surface of the photovoltaic panel body to oblique downward, thereby enhancing the effect of the rotating brush roller in cleaning impurities.

[0018] In a preferred example, the utility model can be further configured as follows: a U-shaped protective cover is provided above the rotation drive device, and the U-shaped protective cover is connected to a corresponding mounting seat.

[0019] By adopting the above technical solution and using the U-shaped protective cover, the damage to the rotary drive device caused by rain and sunlight is reduced, thereby extending the service life of the rotary drive device.
