Description

Technical Field

[0001] The present invention relates to the field of photovoltaic power generation, and in particular to a photovoltaic power station. Background Art

[0002] A photovoltaic power station with energy storage is a new type of power station that combines photovoltaic power generation and energy storage technology, and achieves efficient operation and management of the power station through intelligent technology. The main components of an intelligent photovoltaic power station include a photovoltaic power generation system, an energy storage system, power conversion and distribution facilities, and an intelligent monitoring and control system. The photovoltaic power generation system converts sunlight into electrical energy, and the energy storage system establishes efficient energy storage facilities, such as lithium batteries, to store excess electrical energy. Power conversion and distribution facilities ensure that electrical energy can effectively enter the power grid and be supplied to users when needed, while the intelligent monitoring and control system implements intelligent technology to monitor energy production and consumption, and make real-time adjustments and management.

[0003] The photovoltaic power generation system installs multiple solar photovoltaic panels and uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. When there is sunlight, the solar photovoltaic panels absorb light energy, and opposite charges accumulate at both ends of the panels, generating an electromotive force, which is then stored in batteries.

[0004] When solar photovoltaic panels use light energy to generate electricity, the intensity of sunlight directly determines the power generation efficiency of the photovoltaic panels. The higher the light intensity, the more photons will hit the solar panels per unit time, and the greater the current generated, the higher the power generation efficiency will naturally be. Therefore, during the power generation process of photovoltaic panels, it is necessary to ensure that the solar panels are facing the sun. Solar power generation is generally carried out in areas with rich solar energy resources, such as Gobi and deserts. These areas have a lot of sand and dust. After a period of power generation, dust will accumulate on the surface of the photovoltaic panels, which will also reduce the light received by the photovoltaic panels.

[0005] Therefore, in the process of power generation by photovoltaic panels, it is necessary to change the orientation of the solar panels according to the position of the sun, which is generally achieved through solar trackers. However, when there is a lot of dust on the surface of the photovoltaic panels, resulting in low light intensity, the lighting effect cannot be guaranteed simply by changing the orientation. The surface of the photovoltaic panels must be cleaned regularly to ensure the light intensity received by the photovoltaic panels. At this time, the visual inspection method is generally used, that is, to manually check whether the photovoltaic panels have dust and stains. This is time-consuming and labor-intensive, and is not very practical for large quantities of photovoltaic panels in photovoltaic power stations. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] The photovoltaic power generation system of the intelligent photovoltaic storage power station installs multiple solar photovoltaic panels, uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy, and stores the electrical energy through batteries. The electricity can be used for daily scheduling. When solar photovoltaic panels use light energy to generate electricity, the intensity of sunlight directly determines the power generation efficiency of the photovoltaic panels. The higher the light intensity, the more photons hit the solar panels per unit time, and the greater the current generated, and the power generation efficiency will naturally increase. After a period of normal solar panels generating electricity, dust will accumulate on the surface of the photovoltaic panels, which will also reduce the light received by the photovoltaic panels, so the dust on the surface needs to be cleaned.

[0032] A photovoltaic power station, such as Figure 1-11 As shown, it includes a base 1, a steering mechanism is installed on the top of the base 1, the steering mechanism controls the steering of the photovoltaic panel 2, the steering mechanism includes a first motor 3, the first motor 3 is installed on the top of the base 1, a fixed column 5 is rotatably set on the top of the base 1, the photovoltaic panel 2 is fixedly set on the surface of the fixed column 5, a bevel gear set 4 is installed between the first motor 3 and the fixed column 5, the first motor 3 controls the rotation of the fixed column 5 through the bevel gear set 4, the photovoltaic panel 2 is fixedly set on the outer wall of the fixed column 5, when the photovoltaic panel 2 needs to be rotated to face the sun, the first motor 3 is started, the first motor 3 drives the bevel gear set 4 to rotate, and the fixed column 5 rotates synchronously at the same time, driving the photovoltaic panel 2 fixed on the surface of the fixed column 5 to rotate synchronously, so as to adapt to different light angles and ensure that the light intensity on the surface of the photovoltaic panel 2 is not affected.

[0033] When there is a lot of dust on the surface of the photovoltaic panel 2 and only rotating the photovoltaic panel 2 cannot obtain a better light intensity, it is necessary to use a cleaning mechanism to clean the dust on the surface of the photovoltaic panel 2.

[0034] The cleaning mechanism is composed of a group of brushes 10, a brush head rotating mechanism and a group of brush head cleaning mechanisms. The brush head rotating mechanism controls the rotation of the brush 10 to sweep away the dust on the surface of the photovoltaic panel 2. The brush head rotating mechanism includes a second motor 7. The second motor 7 is installed on the back of the photovoltaic panel 2. The output end of the second motor 7 is connected to the first synchronous belt mechanism 8. One end of the brush 10 is connected to a connecting column 9. The bottom end of one of the connecting columns 9 extends to the bottom surface of the photovoltaic panel 2 and is connected to the first synchronous belt mechanism 8. When it is necessary to clean the dust on the surface of the photovoltaic panel 2, the second motor 7 is started, and the second motor 7 drives the first synchronous belt mechanism 8 to rotate. Then the first synchronous belt mechanism 8 drives the connecting column 9 and the brush 10 to rotate, and the brush 10 cleans the dust on the surface of the photovoltaic panel 2.

[0035] Since the surface area of ​​the photovoltaic panel 2 that needs to be cleaned is large, a group of brushes 10 are required for cleaning. The surfaces of the connecting columns 9 are fixedly provided with mutually meshing residual gears 11. When the first synchronous belt mechanism 8 drives one connecting column 9 to rotate, the other connecting column 9 rotates synchronously under the transmission of the residual gear 11, thereby controlling the brush 10 on the other connecting column 9 to perform cleaning work.

[0036] While the first synchronous belt mechanism 8 drives the connecting column 9 and the brush 10 to rotate and clean, a second synchronous belt mechanism 12 is also provided on the outer wall of the connecting column 9. When the connecting column 9 rotates, the second synchronous belt mechanism 12 is synchronously driven to rotate. One end of the second synchronous belt mechanism 12 is connected to the fixed shaft 18. When the second synchronous belt mechanism 12 rotates, it drives the fixed shaft 18 to rotate, so that the fixed seat 13 is changed from a right-angle state to a straight state. The conveyor belt mechanism 15 is located inside the fixed seat 13, and the conveyor belt mechanism 15 is synchronously changed from a bent state to a straight state.

[0037] Therefore, when the brush 10 is performing a scraping process, some dust will be adsorbed on the surface of the brush 10. At this time, the dust needs to be cleaned, otherwise the cleaning effect of the brush 10 will be poor. A brush head cleaning mechanism is installed on the bottom surface of the photovoltaic panel 2, and the brush head cleaning mechanism includes a fixed seat 13, which is fixedly arranged on the bottom surface of the photovoltaic panel 2. A conveyor belt mechanism 15 is installed inside the fixed seat 13. The conveyor belt mechanism 15 is driven by a third motor 14, and the third motor 14 is located inside the fixed seat 13. A scraper 16 is fixedly arranged on the belt surface of the conveyor belt mechanism 15. When it is necessary to clean the dust on the brush 10, the second synchronous belt mechanism 12 has straightened the fixed seat 13 and the conveyor belt mechanism 15. At this time, the third motor 14 is started, and the third motor 14 drives the conveyor belt mechanism 15 to operate, so that the scraper 16 on the surface moves forward accordingly, and the dust on the surface of the brush 10 is scraped off.

[0038] A foldable limit block 17 is fixedly provided on the top of the fixed seat 13, and the scraper 16 slides along the limit block 17. The limit block 17 can serve as a guide structure for the scraper 16, and the scraper 16 extends from the fixed seat 13 and hangs on the limit block 17. At this time, the limit block 17 can also prevent some dust cleaned by the brush 10 from entering the interior of the fixed seat 13.

[0039] Furthermore, a spring is connected between the mounting portion at one end of the conveyor belt mechanism 15 and the fixed seat 13. When the conveyor belt mechanism 15 is in a bent state, the mounting portion at one end of the conveyor belt mechanism 15 will compress the spring inward, thereby reducing the bending stress on the belt of the conveyor belt mechanism 15. When the conveyor belt mechanism 15 is in a straight state, the mounting portion at one end of the conveyor belt mechanism 15 will move outward under the action of the spring, thereby ensuring that the conveyor belt mechanism 15 is in a straight state for subsequent operation.

[0040] In addition, the activation of the above-mentioned steering mechanism and cleaning mechanism is controlled by the detection mechanism 6. The detection mechanism 6 is installed on the top of the fixed column 5. The detection mechanism 6 includes a light intensity monitoring mechanism and a weather signal receiving device. That is, when the light intensity monitoring mechanism detects the intensity and changes of solar radiation, it provides a reference for the positioning and orientation of the steering mechanism. Those skilled in the art can rotate appropriate sensors and measuring circuits to realize the above functions, such as photoresistors, photodiodes or solar cells. These sensors can convert light intensity into electrical signal outputs. When the light intensity monitoring mechanism has detected the best light angle and adjusted the steering mechanism to rotate the photovoltaic panel 2 into the corresponding position, the power generation is still insufficient. At this time, the weather signal receiving device receives the weather information of the day and analyzes it by the processor. When the weather is clear and the light conditions are good, it indicates that there may be too much dust on the surface of the photovoltaic panel 2 blocking the light source from entering. At this time, the cleaning mechanism is started to clean the photovoltaic panel 2, and the cleaning mechanism is not started when the weather is bad and the light conditions are insufficient.

[0041] The above-mentioned processors, controllers and other mechanisms are existing technologies, and suitable devices can be selected to perform the same work, so they are not numbered and described.

[0042] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
