[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0023] like Figures 1 to 7 In the embodiment of the integrated photovoltaic storage and charging system of the utility model shown, the integrated photovoltaic storage and charging system includes a truss 1, a photovoltaic control module, an energy storage module, an inverter boost module, a transformer rectifier module, a charging pile, a distribution management module and a power grid. The truss 1 is used to install the photovoltaic panel 7, the photovoltaic control module controls the inclination angle of the photovoltaic panel 7, the input end of the energy storage module is electrically connected to the photovoltaic panel 7 and the distribution management module respectively, the output end of the energy storage module is electrically connected to the distribution management module, the input end of the inverter boost module is electrically connected to the distribution management module, the output end of the inverter boost module is electrically connected to the power grid, the power grid is electrically connected to the input end of the transformer rectifier module, the output end of the transformer rectifier module is electrically connected to the distribution management module, and the management module is electrically connected to the charging pile.

[0024] Specifically, the photovoltaic control module adjusts the inclination angle of the photovoltaic panel 7 according to the solar altitude angle, and stores the electric energy converted by the photovoltaic panel 7 by electrically connecting the input end of the energy storage module. When the stored electric energy exceeds a certain capacity, it is distributed to the charging pile or the inverter boost module through the distribution management module, and then connected to the power grid after being distributed to the inverter boost module. When the power consumption is low, the energy storage is insufficient, or the charging pile load is large, the electric energy of the power grid is transformed and rectified and then enters the distribution management module for distribution to the energy storage module or the charging pile. The photovoltaic control module controls the inclination angle of the photovoltaic panel 7 to improve the light conversion efficiency, and the photovoltaic generated electricity is stored and supplied to the charging pile or connected to the grid according to demand through the distribution management module, thereby improving the operating efficiency of the integrated light storage and charging system.

[0025] In one embodiment of the present application, preferably, a pair of parallel grooves 2 are fixedly connected to the truss 1, a slide groove 3 is provided on one side of the groove 2, a wheel axle 4 is slidably connected in the slide groove 3, a running wheel 5 is fixedly connected to the wheel axle 4, a base 6 is provided on the running wheel 5, a photovoltaic panel 7 is mounted on the base 6, a telescopic push rod 8 is hinged on the top of the back of the photovoltaic panel 7, and the other end of the telescopic push rod 8 is hinged on the truss 1. Specifically, the running wheel 5 is placed in the groove 2, so that the running wheel 5 moves in the groove 2, and after walking to one end of the slide groove 3, the length of the telescopic push rod 8 is adjusted according to the altitude angle of the sun, so that the angle of sunlight irradiating the photovoltaic panel 7 becomes larger, the light conversion efficiency is improved, and the power generation ratio of photovoltaic power generation in the integrated light storage and charging system is improved.

[0026] In one embodiment of the present application, preferably, there are multiple groups of slide grooves 3, axles 4, walking wheels 5 and bases 6 on a pair of grooves 2, and each group of bases 6 is mounted with photovoltaic panels 7. The bases 6 and axles 4 are rotatably connected. Specifically, the number of groups of photovoltaic panels 7 that can be placed can be designed according to the solar altitude angle of the power station location and the length of the grooves 2. The lower the latitude of the power station location, the more groups that can be placed. Conversely, the higher the latitude, the fewer groups that can be placed.

[0027] In one embodiment of the present application, preferably, a rotating column 9 is fixedly connected to the side of the photovoltaic panel 7, and a linkage piece 10 is rotatably connected to the rotating column 9, so that multiple groups of photovoltaic panels 7 can be adjusted simultaneously when adjusting the angle of the photovoltaic panel 7, thereby avoiding mutual influence caused by inconsistent inclination angles of each photovoltaic panel 7.

[0028] In one embodiment of the present application, preferably, a reversible motor 11 is fixedly mounted on the base 6 , and a driving shaft of the reversible motor 11 is fixedly connected to the wheel axle 4 for driving the walking wheel 5 to move forward and backward in the groove 2 .

[0029] In one embodiment of the present application, preferably, a rack 12 is fixedly connected in the groove 2, a gear 13 is fixedly connected on the walking wheel 5, and the gear 13 is engaged with the rack 12 to drive the base 6 to move forward and backward in the groove 2 to avoid slipping. The photovoltaic panel 7 is heavy to avoid unpowered sliding and sliding when the wind blows.

[0030] In one embodiment of the present application, preferably, the length of the slide groove 3 is equal to the length of the linkage piece 10 between adjacent photovoltaic panels 7, so as to ensure that the adjacent photovoltaic panels 7 are arranged in parallel to avoid mutual blocking.

[0031] To sum up, the integrated photovoltaic storage and charging system in the above-mentioned embodiment of the utility model, specifically, designs the number of photovoltaic panels 7 according to the latitude of the power station and the length of the groove 2, installs the base 6 of multiple photovoltaic panels 7 and the gear 13 of the walking wheel 5 on the rack 12 in the groove 2, starts the reversible motor 11 to make the gear 13 drive the base 6 of the photovoltaic panel 7 to move toward one end of the slide 3, and under the action of the telescopic push rod 8, the inclination angle of the photovoltaic panel 7 gradually decreases. When the reversible motor 11 moves to one end of the slide 3, the telescopic push rod 8 is in the initial position. At this time, the inclination angle of the photovoltaic panel 7 is the smallest, and the illuminated area of ​​the photovoltaic panel 7 is slightly larger than the floor area; the reversible motor 11 drives the gear 13 in reverse to move to the other end of the slide 3, starts the telescopic push rod 8 to extend, and makes the inclination angle of the photovoltaic panel 7 gradually increase. When it runs until the sunlight can cover all the photovoltaic panels 7 without dead angles, the illuminated area of ​​the photovoltaic panel 7 is the largest. This device utilizes a movable photovoltaic panel base and a telescopic push rod to adjust the working angle of the photovoltaic panel according to the altitude angle of the sun, while increasing the number of photovoltaic panels, so that the illumination angle of the photovoltaic panel is better and the illumination area of ​​the photovoltaic panel is increased, which not only improves the light conversion efficiency but also increases the amount of photovoltaic panels laid per unit area of ​​land, and ultimately can improve the power generation ratio of photovoltaic power generation in the integrated light-storage-charging system.
