Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation equipment, and in particular to a photovoltaic power generation equipment with an intelligent cleaning function. Background Art

[0002] Photovoltaic power generation refers to a power generation method that uses solar photovoltaic cells to directly convert solar radiation energy into electrical energy. Photovoltaic power generation is the mainstream of solar power generation today. Photovoltaic power generation has the advantages of making full use of local solar energy resources and replacing and reducing fossil energy consumption. Since photovoltaic panels are mostly installed outdoors and there are many impurities such as fallen leaves and dust outdoors, which will affect the normal use of photovoltaic panels, a cleaning component is required to spray water on the surface of the photovoltaic panels and clean them back and forth, which can effectively clean the dirt adsorbed on the surface of the photovoltaic panels; since the cleaning brush in the cleaning component fits the surface of the photovoltaic panel, the cleaning brush pushes back a small amount of impurities on the photovoltaic panel after each push back, resulting in a small amount of impurities pushing back to cause secondary pollution to the surface of the photovoltaic panel, resulting in some areas on the photovoltaic panel being cleaned, while some places are still dirty, requiring extra time to clean the dirt on the surface of the photovoltaic panel, increasing the cleaning time of the photovoltaic panel. Summary of the invention

[0003] The purpose of the present invention is to provide a photovoltaic power generation equipment with an intelligent cleaning function. Through the setting of the cleaning component, the cleaning roller brush can be lifted on the photovoltaic panel, which can prevent the cleaning roller brush from contacting the surface of the photovoltaic panel when pushing back, and avoid the cleaning roller brush pushing back a small amount of impurities on the photovoltaic panel after each push back, thereby reducing secondary pollution to the surface of the photovoltaic panel, thereby improving the cleaning effect of dirt on the surface of the photovoltaic panel, reducing the cleaning time of dirt on the surface of the photovoltaic panel, so as to solve the above-mentioned deficiencies in the technology.

[0004] In order to achieve the above object, the present invention provides the following technical solution: a photovoltaic power generation device with intelligent cleaning function, comprising:

[0005] Photovoltaic panels and photovoltaic brackets, the photovoltaic brackets are symmetrically mounted with two movable rails on the outside, the movable rails are mounted with movable cleaning roller brushes, and the cleaning roller brushes are used to clean the surface of the photovoltaic panels;

[0006] Two groups of cleaning components are used to reset and lift the cleaning roller brush on the moving rail and separate the cleaning roller brush from the photovoltaic panel. Each group of the cleaning components includes a geometric frame slidably installed in the moving rail and a connecting column rotatably connected to one end of the cleaning roller brush, and one side of the geometric frame is recessed downward to form a movable cavity. A connecting column is installed on the outside of the connecting column. A liquid receiving component for blocking the moving block is provided on the connecting column. One end of the connecting column extends into the movable cavity and is installed with a moving block. The bottom of the geometric frame is provided with a connecting rod group that drives the moving block to move up and down Parts; and the liquid receiving assembly and the connecting rod assembly are adapted to each other. When the connecting rod assembly moves upward on the driving connection column, the distance between the cleaning roller brush and the photovoltaic panel is constantly increasing, and then the liquid receiving assembly moves to the bottom of the cleaning roller brush, forming a short gap between the bottom of the cleaning roller brush and the photovoltaic panel. When the connecting rod assembly moves downward on the driving connection column, the distance between the cleaning roller brush and the photovoltaic panel is constantly decreasing, and then the liquid receiving assembly slides over the bottom of the cleaning roller brush, removing the gap between the bottom of the cleaning roller brush and the photovoltaic panel, making it easier for the cleaning roller brush to clean the surface of the photovoltaic panel.

[0007] Preferably, the liquid receiving assembly includes a liquid receiving plate arranged on the outside of the cleaning roller brush, a rack installed at the bottom of the connecting column and a gear sleeved on the outside of the connecting column, and the gear is meshed with the rack, a rotatable connecting ring is installed at one end of the gear, and the bottom of the connecting ring is fixed to the top of the geometric frame, a connecting arm is jointly installed between the gear and the liquid receiving plate, a stabilizing assembly is provided on the outside of the connecting column, and the stabilizing assembly is used to keep the liquid receiving assembly stable on the connecting column; and the liquid receiving plate can collect water seeping from the bottom of the cleaning roller brush to prevent excess water from directly dripping on the surface of the photovoltaic panel when the cleaning roller brush is reset, and the liquid receiving plate can discharge excess water inside it to the outside when it is tilted, so that the water is directly discharged from the surface of the cleaning roller brush, but the interior of the connecting ring and the gear are both hollow structures, which facilitates the connecting column to move upward or downward along the connecting ring and the gear, and the bottom of the connecting column is recessed inward to form a hollow cavity, which can prevent the connecting column, the connecting ring and the gear from interfering with each other.

[0008] Preferably, a detachable absorbent sponge is also installed on the top of the liquid receiving plate, and the liquid receiving plate is a U-shaped structure, and the shape of the absorbent sponge is consistent with the liquid receiving plate; and the U-shaped structure of the absorbent sponge enables the absorbent sponge to absorb the water collected in the liquid receiving plate, which can alleviate the situation where water overflows due to movement in the liquid receiving plate, and further ensure the cleanliness of the surface of the photovoltaic panel.

[0010] Preferably, the connecting rod assembly includes a servo motor installed at the bottom of the geometric frame and a guide block fixed at the bottom of the moving block, and the output end of the servo motor extends into the active cavity and is fixed with a cam, one end of the cam is installed with a connecting shaft, the outer sleeve of the connecting shaft is provided with a connecting rod arm, a slide is fixed to the top of the connecting arm, a slide groove is provided at one end of the slide, and the slide groove and the guide block are slidably connected; and the slide slides along the outside of the guide block under the action of the slide groove, and the length of the guide block is matched with the slide to prevent the slide from sliding off the guide block, which can ensure that the connecting column slides up or down stably in the active cavity, and at the same time, the connecting rod assembly can lift the cleaning roller brush when pushing it back, which can reduce the wear of the cleaning roller brush itself, improve the service life of the cleaning roller brush, and reduce the maintenance cost of the cleaning roller brush.

[0011] Preferably, a sleeve is also fixed to the top of the connecting column, and the sleeve is sleeved on the outside of the connecting column. A limiting ring is fixed in the sleeve, and a limiting groove for the limiting ring to rotate is opened on the outside of the connecting column; through the setting of the sleeve, mutual interference between the connecting column and the connecting column can be prevented, so that the connecting column can be moved upward or downward by the connecting column, and at the same time, the connecting column can be rotated along the sleeve, so that the cleaning roller brush rolls along the surface of the photovoltaic panel.

[0012] Preferably, a first screw hole is provided at the bottom of the connecting column, a second screw hole is provided at the top of the moving block, a threaded column is screwed on the connecting column, and the first screw hole is screwed into the second screw hole corresponding to the first screw hole through the first screw hole.

[0015] 2. Through the setting of the liquid receiving component, the liquid receiving plate can be moved to the bottom of the cleaning roller brush when the cleaning roller brush is lifted, so that a temporary barrier can be formed between the bottom of the cleaning roller brush and the surface of the photovoltaic panel, thereby preventing excess water at the bottom of the cleaning roller brush from dripping directly onto the surface of the photovoltaic panel when the cleaning roller brush is reset, thereby further improving the dirt cleaning effect on the surface of the cleaning roller brush.

[0016] 3. By setting up the stabilizing components, the load on the connecting column can be dispersed and balanced, part of the force on the connecting column can be borne, and additional auxiliary support can be ensured for the connecting column, thereby extending the service life of the connecting column.
