Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic bracket applications, and in particular relates to an autonomous cleaning mechanism for photovoltaic module intelligent cleaning robot replacement vehicle for solar panels. Background Technology

[0002] Currently, the photovoltaic modules used by the intelligent cleaning robot for photovoltaic modules to power itself are usually exposed to places with large wind and sand. Because they do not have a self-cleaning function, the photovoltaic modules they carry will be covered with dust and dirt over time, resulting in low photoelectric conversion efficiency and seriously affecting the working efficiency of the intelligent cleaning robot for photovoltaic modules. Manual dust removal is also inconvenient and difficult to operate. Summary of the Invention

[0003] In view of this, the technical problem to be solved by this utility model is to provide an autonomous cleaning mechanism for the solar panels of a photovoltaic module intelligent cleaning robot with a simple structure and convenient fixing, thereby solving the problem of the inability to self-clean.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an autonomous cleaning mechanism for solar panels of a photovoltaic module intelligent cleaning robot for a replacement vehicle, which cleans the solar panels of the replacement vehicle, including a movable frame with a brush at one end, a fixed frame, a brush placement plate installed on the side of the solar panel, a rotating shaft and a limiting support angle steel. The other end of the movable frame is rotatably connected to one end of the fixed frame through the rotating shaft. The other end of the fixed frame is fixedly installed at the end of the track of the replacement vehicle. The limiting support angle steel is fixedly installed on the fixed frame and supports the movable frame. The height of the brush is adapted to contact the solar panel.

[0005] The active frame adopts an H-shaped structure, and the H-shaped structure and the brush form an O-shaped structure that does not obstruct the solar panel.

[0006] A tension spring is installed between the movable frame and the fixed frame at the rotating joint.

[0007] The surface of the solar panel is set to be either tilted or horizontal; when the surface is tilted, the height near the brush end is lower than the height of the other end where the brush placement plate is installed, and the height of the brush is closely matched with the height of the lower end of the solar panel.

[0008] A limiting angle steel is also installed above the pivot of the fixed frame.

[0009] The working principle of this utility model is to use gravity or gravity and spring tension to make the brush closely adhere to the photovoltaic module and clean the surface. Its structure is simple and easy to use. No manual operation or external power is required. The combination of H-shaped structure and brush can avoid blocking the photovoltaic module after cleaning and prevent hot spots from burning the photovoltaic module.

[0010] The advantages of this utility model are that it has a simple structure, is easy to use, requires no manual operation or external power, and not only ensures the power generation efficiency of the self-powered photovoltaic modules (battery panels) of the vehicle, but also reduces maintenance costs.

[0016] The preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] Implementation, for example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides an autonomous cleaning mechanism for photovoltaic module intelligent cleaning robot swapping carts of solar panels, which cleans the surface of photovoltaic modules, i.e., solar panels 7. It includes a movable frame 3 with a brush 2 at one end, a fixed frame 5, a brush placement plate 1 installed on the side of the solar panel, a rotating shaft 4, a limiting angle steel 8, and a limiting support angle steel 6. The other end of the movable frame 3 is rotatably connected to one end of the fixed frame 5 via a rotating shaft 4 with a bolt structure. The other end of the fixed frame 5 is fixedly installed at the end point of the swapping cart's travel track. The limiting support angle steel 6 is fixedly installed below the rotating shaft 4 of the fixed frame 5 to support the movable frame 3. The limiting angle steel 8 is fixedly installed above the rotating shaft 4 of the fixed frame 5 to safely limit the movable frame 3. The height of the brush 2 is adapted to contact the solar panel 7.

[0018] In this embodiment, the brush placement plate 1 is fixed to the end of the photovoltaic module, and the brush 2 is fixed to the front end of the movable frame 3 of the H-shaped frame structure. The movable frame 3 and the brush 2 form an O-shaped structure that does not obstruct the photovoltaic module. When the brush 2 is in a stationary state on the brush placement plate 1, the O-shaped structure does not obstruct the surface of the photovoltaic module. The end of the movable frame 3 is rotatably connected to the fixed frame 5 via a pivot 4, and the range of the movable frame 3's descent is limited by a limiting support angle steel 6. Before the trolley returns to the initial position at the end, the movable frame 3 is stopped in a fixed position by the limiting support angle steel. When the trolley returns to the initial position at the end, the surface of the photovoltaic module and the brush 2 directly contact each other due to gravity. Alternatively, a tension spring can be connected and installed between the movable frame and the fixed frame at the rotatable connection to increase the gravity of the movable frame 3 and improve the cleaning effect.

[0019] In this embodiment, the surface of the photovoltaic module is set in an inclined state. Since the brush placement plate end of the photovoltaic module is higher than the height of the end closest to the brush, this tail-high-head-low setting allows the brush 2 to move along the surface of the photovoltaic module and brush the photovoltaic module under the action of gravity. The movable frame 3 is gradually raised until the transfer trolley reaches the initial position of the end point, and the brush 2 reaches the highest point and stops on the brush placement plate 1. Conversely, when the transfer trolley leaves the initial position of the end point, the brush 2 leaves the brush placement plate 1 and moves downward along the photovoltaic module under the action of gravity until the transfer trolley leaves and the movable frame 3 is lifted by the limiting support angle steel 6 and stops falling.

[0020] The main advantage of this embodiment is that it is used for the autonomous cleaning of the solar panels of the photovoltaic module intelligent cleaning robot. It has a simple structure, is easy to use, requires no manual operation or external power, and not only ensures the power generation efficiency of the photovoltaic modules powered by the robot, but also reduces maintenance costs.
