Make full use of the available space and light angles of the building, lay photovoltaic panels, and build photovoltaic building integrated power generation and grid-connected storage and charging system equipment.

[0003] At present, in the process of designing storage and charging systems for photovoltaic building integrated power generation and grid connection, in order to improve the photovoltaic panels to receive stronger light, photovoltaic panel mounting frames with adjustable angles are used to adjust the inclination of photovoltaic panels. However, when used in an integrated structure with a building, the following problems often exist: when installing photovoltaic panels with adjustable inclination angles, the installation spacing between adjacent photovoltaic panels is generally large, to avoid the adjacent photovoltaic panels receiving light and generating reflected light, which affects the structure of the adjacent photovoltaic panels themselves; in addition, since the space available for the layout of the photovoltaic system in the building is limited, the layout of the photovoltaic panels is more limited, which in turn leads to a low storage and charging efficiency of the storage and charging system for photovoltaic building integrated power generation and grid connection.

DETAILED DESCRIPTION

[0023] Reference Figure 1-6The present invention provides a technical solution: a storage and charging device applied to photovoltaic building integrated power generation and grid connection, comprising a mounting frame 1 and a rotating frame 32, wherein a storage and charging module 2 is mounted at the bottom of the mounting frame 1, and a concave shell plate 3 distributed front and rear is mounted on the upper end of the mounting frame 1, and the left and right ends of the rotating frame 32 are rotatably connected to the left and right ends of the concave shell plate 3 respectively, and a motor 31 for adjusting the rotation angle of the rotating frame 32 is mounted on the right end of the concave shell plate 3, a photovoltaic panel 4 is mounted on the upper end of the rotating frame 32, and a reflection mechanism 5 is mounted on the lower end of the rotating frame 32, and the reflection mechanism 5 is used to reflect the light reflected by the adjacent photovoltaic panel 4 toward the photovoltaic panel 4 again, thereby making full use of the strong light from the sun.

[0024] In this embodiment, the reflection mechanism 5 includes a fixed shaft 51, a slave gear 52 and a second motor 54. The fixed shaft 51 is symmetrically installed at the front and rear ends of the rotating frame 32, and the slave gear 52 is symmetrically installed at the center of the left and right ends of the rotating frame 32. A swing plate 55 is fixed to the slave gear 52. A second rotating shaft 57 is rotatably installed at the lower end of the swing plate 55 and on the plate surface close to the upper side. The second rotating shaft 57 is symmetrically arranged front and back. A third motor 58 for regulating the rotation of the second rotating shaft 57 is installed at the lower end of the swing plate 55, and a flexible reflecting sheet 59 is wound on the second rotating shaft 57. The outer end of the flexible reflecting sheet 59 is connected to the fixed shaft 51. The second motor 54 is installed at the right end of the rotating frame 32. A main gear 53 meshing with the slave gear 52 is installed on the output shaft of the second motor 54. That is to say, when the photovoltaic panel is adjusted to tilt to receive vertical strong light, the light reflected on the photovoltaic panel will have local light emitted to the adjacent On the back of the photovoltaic panel, these local light rays (the light reflected from the photovoltaic panel, there will be local light rays directed to the back of the adjacent photovoltaic panel) will heat up the adjacent photovoltaic panel, thereby damaging the internal structure of the photovoltaic panel and reducing the photoelectric conversion efficiency of the photovoltaic panel; therefore, by arranging the reflection mechanism on the back of the photovoltaic panel, these local light rays are reflected by the reflection effect of the flexible reflection sheet, so as to have an interception effect, thereby preventing these local light rays from being directed to the back of the adjacent photovoltaic panel, preventing the adjacent photovoltaic panel from being heated up after being irradiated by these local light rays, and further reducing the influence of the temperature rise on the structure of the adjacent photovoltaic panel itself, thereby greatly reducing the distance between adjacent photovoltaic panels, thereby increasing the layout density of photovoltaic panels, and further increasing the layout quantity of photovoltaic panels, thereby fully improving the utilization rate of the storage and charging space of photovoltaic building integrated power generation and grid connection on the building, and improving the storage and charging capacity of photovoltaic building integrated power generation and grid connection;

[0025] In addition, specifically, the main gear is controlled by motor 2 to drive the slave gear to rotate, and the slave gear drives the pendulum plate to swing. At the same time, two groups of motors 3 cooperate to control the rotation of shaft 2 to reel in and unreel the flexible reflective sheet, and adjust the inclination angle of the flexible reflective sheet so that the light reflected by the flexible reflective sheet is reflected again toward the surface of the photovoltaic panel, thereby improving the utilization rate of light by the photovoltaic panel.

[0026] In this embodiment, a rotating shaft 56 is rotatably installed at the lower end of the swing plate 55 and on the plate surface close to the lower side. The rotating shaft 56 is symmetrically arranged front to back, and the flexible reflective sheet 59 bypasses the lower axial surface of the rotating shaft 56; wherein the center of the circle formed by the rotating shaft 56 and the fixed shaft 51 is concentrically arranged with the center of the gear 52; this is beneficial to adjusting the incident angle and reflection angle of these local light rays directed toward and emitted from the flexible reflective sheet, thereby facilitating the increase of the amount of light that can be emitted to the surface of the photovoltaic panel again after these local light rays are reflected by the flexible reflective sheet, and facilitating the adjustment of emitting light to the surface of the photovoltaic panel again at a smaller incident angle.

[0027] In this embodiment, a cleaning roller 510 is rotatably installed at the lower end of the swing plate 55 and on the lower side of the plate surface. The cleaning roller 510 is arranged between two sets of rotating shafts 56, and the cleaning roller surface of the cleaning roller 510 is in contact with the reflecting surface of the flexible reflecting sheet 59. A motor 511 for regulating the rotation of the cleaning roller 510 is installed at the lower end of the swing plate 55, so that the cleaning roller can better clean the surface of the flexible reflecting sheet, thereby ensuring the reflection effect of the flexible reflecting surface.

[0028] In the present embodiment, a reflective surface positioning system is also included, and the reflective surface positioning system includes an angle monitoring module 1 and an angle monitoring module 2. The angle monitoring module 1 is used to monitor whether the photovoltaic panel is tilted, and judge the tilt direction of the photovoltaic panel, and determine the flexible reflective sheet of the reflective surface that needs to be adjusted. The angle monitoring module 2 is used to monitor whether the reflective surface that needs to be adjusted is vertical, and feedback the reflection mechanism to adjust the reflective surface to be in a vertical state. The judgment process of whether the photovoltaic panel is tilted is as follows: when the front end of the rotating frame is lower than or higher than the upper end of the concave shell plate, the photovoltaic panel is in a tilted state; the judgment process of the tilt direction of the photovoltaic panel is as follows: when the front end of the rotating frame is lower than the upper end of the concave shell plate, the photovoltaic panel tilts forward, and when the front end of the rotating frame is higher than the upper end of the concave shell plate, the photovoltaic panel tilts backward;

[0029] In this embodiment, when the photovoltaic panel is adjusted to tilt, the angle monitoring module 1 monitors and obtains the angle α between the photovoltaic panel and the horizontal plane at the first time. Since the center of the circle formed by the rotating shaft 56 and the fixed shaft 51 is concentric with the center of the slave gear 52, the reflecting surfaces of the two flexible reflecting sheets are in a vertical state, and the angle β between the primary reflecting surface and the photovoltaic panel is 90°-α. The angle monitoring module 2 monitors and determines whether the angle γ between the reflecting surface to be adjusted and the photovoltaic panel is equal to β, and the reflecting mechanism quickly adjusts and positions the reflecting surface to be adjusted to be in the primary reflecting surface state (i.e., γ=β).

[0030] In this embodiment, a first temperature sensor 6 and a second temperature sensor 7 are also included. The first temperature sensor 6 and the second temperature sensor 7 are respectively installed at the front and rear ends of the rotating frame 32. The first temperature sensor 6 monitors and records the real-time temperature T1, and the second temperature sensor 7 monitors and records the real-time temperature T2. The primary reflecting surface is regulated by the reflecting mechanism to perform fluctuation regulation of tilting forward and tilting backward. The state of the reflecting surface at (T1+T2)max is recorded as the secondary reflecting surface, and the reflecting mechanism regulates the primary reflecting surface to be converted into the secondary reflecting surface; that is, after the state of the primary reflecting surface is completed, and the position of the photovoltaic panel maintains a certain state for a short time , then the positioning adjustment of the secondary reflection surface state is performed, otherwise, the reflection surface needs to be adjusted to the primary reflection surface state; wherein, by fine-tuning the inclination angle of the reflection surface, a flexible reflection sheet in the secondary reflection surface state is formed, which can further change the incident angle and reflection angle of these local light rays directed to and emitted from the adjacent photovoltaic panels, as well as the incident angle of these local light rays reflected by the flexible reflection sheet and emitted again to the photovoltaic panel, wherein the secondary reflection surface obtained by the cooperation of the first temperature sensor and the second temperature sensor can make these local light rays act on the photovoltaic panel again to the maximum extent and be utilized by the photovoltaic panel, thereby further improving the utilization rate of light by the photovoltaic panel.

[0034] S3: Obtain a primary reflection surface or a secondary reflection surface through a reflection surface positioning system.

[0035] The above description is only a preferred specific implementation manner of the invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the invention, which should be covered by the protection scope of the present invention.
