[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Examples, such as Figures 1-6 As shown, this utility model provides a photovoltaic-storage-charging system for green buildings, comprising a solar power generation system, an energy storage system, and a charging system. The solar power generation system includes photovoltaic modules, an inverter, a photovoltaic grid-connected cabinet, and a distribution cabinet. The energy storage system includes a battery, an energy storage converter, a battery management system, and an energy management system. The charging system includes a charging pile and a charging rack 1. The solar power generation system, energy storage system, and charging system are existing technologies and will not be described in detail in this embodiment. This utility model applies a photovoltaic-storage-charging system to green buildings, which can improve the overall utilization rate of electricity in green buildings and alleviate grid pressure.

[0022] Considering that the canopy 1 can be used as the installation base for photovoltaic modules in green buildings, in order to ensure that the surface dust of the photovoltaic modules can be automatically cleaned regularly, this utility model provides an automatic cleaning device 2 on the top of the canopy 1. Specifically, the canopy 1 provided by this utility model has a T-shaped structure. The automatic cleaning device 2 includes a canopy box 21 set in the middle of the top of the canopy 1. A U-shaped movable frame 22 is set on the outside of the canopy box 21. The left and right spacing of the movable frame 22 is half the width of the canopy 1, and the front and back spacing of the movable frame 22 is equal to the length of the canopy 1. Side brushes 23 are set on both the left and right sides of the movable frame 22. Racks 24 are set on both the front and back sides of the movable frame 22. Gears 25 meshing with racks 24 are set on the transmission side of racks 24. A gear motor 26 is set on the power input end of gear 25. Among them, the geared motors 26 are arranged in pairs at the front and rear ends of the roof box 21, and are used to drive the gears 25 and racks 24 connected to them respectively. The gears 25 and racks 24 are used to drive the moving frame 22 to move back and forth on the top of the roof frame 1, and the left and right movement range of the moving frame 22 does not exceed the maximum left and right distance of the roof frame 1. The moving frame 22 carries a side brush 23 to clean the photovoltaic modules on the top of the roof frame 1. The side brush 23 can effectively cover the front and rear distance of the roof frame 1 in its unit working length of left and right reciprocating movement, which is conducive to the regular automatic cleaning of dust accumulation and avoids the impact of untimely dust cleaning on the performance of photovoltaic modules.

[0023] Furthermore, the canopy box 21 provided by this utility model has mounting slots 211 at both the front and rear ends for mounting the reduction motor 26. By mounting the reduction motor 26 in the mounting slots 211, on the one hand, it provides concealed installation conditions for the reduction motor 26, and on the other hand, it provides sufficient transmission distance for the meshing of the rack 24 and the gear 25. This is beneficial to improving the spatial compactness from the reduction motor 26 to the inner side of the moving frame 22, and to ensuring that the moving frame 22 has a stable moving path at both the front and rear ends of the canopy box 21, thereby improving the actual working performance of the automatic cleaning device 2.

[0024] In order to improve the cleaning efficiency of the automatic cleaning device 2, the roof box 21 provided by this utility model is provided with air vent slots 212 on both the left and right sides. Multiple pairs of air outlets 213 are provided in the air vent slots 212, which are distributed along their length and communicate with the interior of the roof box 21. Multiple air blowers 27 are provided on the side of the roof box 21 at intervals. The air blowers 27 are used to blow air into the roof box 21 and exhaust the air through the air outlets 213. As the moving frame 22 carries the side brush 23 towards the roof box 21, the dust on the surface of the photovoltaic modules on one side of the roof box 21 is cleaned by the side brush 23, while some of the dust on the surface of the photovoltaic modules on the other side of the roof box 21 is scraped towards the roof box 21. The blower 27 provides air pressure to the interior of the roof box 21, and the air pressure is output from the air outlet 213. This air pressure can blow away the dust that has moved to the bottom of the air vent 212. Some of the dust is blown directly away from the photovoltaic modules, while the other part of the dust is carried away from the photovoltaic modules by the side brush 23 as it moves in the opposite direction, thereby improving the cleaning effect of the automatic cleaning device 2 on the surface of the photovoltaic modules.

[0025] To improve the utilization rate of the side brush 23, the side brush 23 provided by this utility model adopts a design that is detachable from the moving frame 22. Specifically, the vertical height of the left and right sides of the moving frame 22 is less than the vertical height of the front and rear ends of the moving frame 22. The side brush 23 includes an H-shaped brush holder 231, which is connected to the moving frame 22 by screws. Several bristles 232 are provided on the inner bottom of the brush holder. The front and rear ends of the moving frame 22 can move against the top surface of the frame 1 to improve the balance of the moving frame 22. The left and right sides of the moving frame 22 provide installation conditions for the brush holder and allow a certain amount of working deformation allowance for the bristles 232, which is convenient for the bristles 232 to clean accumulated dust. The upper groove of the brush holder 231 is used to insert into the side plate of the moving frame 22, the lower groove of the brush holder is used to bond the bristles 232, and the side of the brush holder 231 is effectively fixed to the moving frame 22 by screws. In this way, if the quality of the bristles 232 significantly affects the cleaning effect, the brush holder 231 can be replaced together with the bristles 232, which helps to ensure the actual cleaning quality of the automatic cleaning device 2.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
