[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0051] Example 1

[0052] like Figure 1 , Figure 2 As shown, a photovoltaic storage and charging integrated system includes:

[0053] At least one charging station for charging electric vehicles;

[0054] The busbar is connected to the charging pile and used to transmit electric energy;

[0055] At least one photovoltaic module for absorbing sunlight;

[0056] At least one photovoltaic inverter is provided between the photovoltaic module and the busbar, and is used to convert light energy into electrical energy and transmit the electrical energy to the busbar;

[0057] At least one battery module is used to store the electric energy transmitted by the busbar or transmit the electric energy to the busbar;

[0058] At least one energy storage inverter is arranged between the battery module and the busbar, and is used to transmit the electric energy on the busbar to the battery module, or transmit the electric energy on the battery module to the busbar;

[0059] The photovoltaic assembly includes two groups of solar panels 10 , and the solar panels 10 have a horizontal working state and a vertical relative distribution state.

[0060] The technical solution provides an integrated photovoltaic, storage and charging system, in which photovoltaic modules and photovoltaic inverters are power generation modules, battery modules and energy storage inverters are energy storage modules, and charging piles are charging modules, integrating photovoltaic, storage and charging to realize the storage and utilization of solar energy.

[0061] In the present technical solution, a photovoltaic integrated system is provided, and when there is sunlight during the day, the solar panel 10 is adjusted to a horizontal working state, such as Figure 7 As shown, at night or during bad weather, the solar panels 10 are folded up, that is, the two solar panels 10 are adjusted to a vertical relative distribution state, such as Figure 8 , Fig. 9 As shown, the solar panel 10 is protected to reduce the possibility of damage to the solar panel 10 and ensure the power generation efficiency of the integrated photovoltaic storage and charging system.

[0062] like Figure 2 As shown, the photovoltaic assembly further includes two groups of retractable components 30 and a group of limiting components 40. The two groups of retractable components 30 are adapted to the two groups of solar panels 10, and the limiting components 40 are located between the two groups of retractable components 30.

[0063] The retractable component 30 includes a longitudinally arranged electric push rod 1 31 and an electric push rod 2 32, and the solar panel 10 is hinged to the output end of the electric push rod 1 31; the limiting component 40 includes a transversely arranged double-headed sleeve 41, and both ends of the double-headed sleeve 41 are movably connected with a long rod 43, and a spring 42 is connected between the long rod 43 and the double-headed sleeve 41.

[0064] The photovoltaic components in this technical solution, such as Figure 7 As shown, when the solar panel 10 is in a horizontal working state, the output end of the second electric push rod 32 supports the lower end of the solar panel 10. At this time, the second electric push rod 32 is in an initial position, and the movable end of the long rod 43 contacts the upper end of the solar panel 10.

[0065] like Figure 8 , Fig. 9As shown, when the solar panel 10 is to be folded, the solar panel 10 is first adjusted to a vertical relative distribution state, and the working surfaces of the two solar panels 10 are arranged relative to each other. At this time, the overall length of the second electric push rod 32 is first controlled to extend, and the solar panel 10 is pushed to rotate until the output end of the second electric push rod 32 and the active end of the long rod 43 respectively contact the two sides of the solar panel 10; then the overall length of the first electric push rod 31 is controlled to shorten, and the solar panel 10 is driven to move downward. In the process of the solar panel 10 moving downward, the overall length of the second electric push rod 32 can be controlled to shorten to the initial position at the same time;

[0066] like Figure 7 , Fig. 9 As shown, when the solar panel 10 is released, the overall length of the electric push rod 1 31 is controlled to extend first, driving the solar panel 10 to move upward into position. During the movement, due to the setting of the spring 42 in the limit member 40, the long rod 43 conflicts with the solar panel 10. After the solar panel 10 passes over the electric push rod 2 32, it rotates in the direction of the electric push rod 2 32, and the lower end surface of the solar panel 10 contacts the output end of the electric push rod 2 32.

[0067] In the technical solution, a photovoltaic storage and charging integrated system is configured with photovoltaic components. When there is sunlight during the day, the solar panel 10 is adjusted to a working state, and when it is bad weather at night or during the day, the solar panel 10 is folded up. That is, two solar panels 10 are arranged opposite to each other to protect the solar panels 10, reduce the possibility of damage to the solar panels 10, and ensure the power generation efficiency of the photovoltaic storage and charging integrated system.

[0068] To reduce the possibility of damage to the solar panel 10, Figure 2 As shown, the output end of the second electric push rod 32 is rotatably matched with the roller 1 321, and the sliding contact between the output end of the second electric push rod 32 and the solar panel 10 is changed to a rolling contact between the roller 1 321 and the solar panel 10, and when the second electric push rod 32 supports or limits the solar panel 10, the friction between the second electric push rod 32 and the solar panel 10 is reduced;

[0069] The movable end of the long rod 43 is rotatably matched with the roller 2 44, which changes the sliding contact between the movable end of the long rod 43 and the solar panel 10 into a rolling contact between the roller 2 44 and the solar panel 10. When the long rod 43 limits the upper end or side of the solar panel 10, the friction between the long rod 43 and the solar panel 10 is reduced, thereby reducing the possibility of damage to the solar panel 10.

[0070] Furthermore, in order to avoid damage to the solar panels during deployment and retraction, which would affect the power generation efficiency, Figure 2 , Figure 3 , Figure 4 As shown, the solar panel 10 includes a panel body 11 and a housing 12 with an upper opening, the panel body 11 is assembled inside the housing 12; the output end of the electric push rod 1 31 is hinged to the housing 12; and the roller 2 44 has two thickened head ends 441.

[0071] During the operation of the solar panel 10 , the roller 1 321 contacts the panel body 11 , and the thickened head end 441 on the roller 2 44 contacts and cooperates with the outer shell 12 . External components do not directly contact the panel body 11 , thereby reducing the possibility of damage to the panel body 11 .

[0072] To further protect the photovoltaic modules and avoid damage to them caused by bad weather, such as Figure 2 As shown, the photovoltaic component also includes a substrate 20. In this embodiment, the substrate 20 can be adjusted according to actual conditions. For example, the upper end surface of the substrate 20 is adjusted to a high and low end setting, so that the solar panel 10, which was originally in a horizontal working state, is set as a whole facing the sun. A protective shell 21 is set on the substrate 20, and the retractable component 30 is set inside the protective shell 21; that is, when the solar panel 10 is not in use and is retracted, it enters the interior of the protective shell 21, and the protective shell 21 isolates the solar panel 10 from the outside, thereby achieving the effect of protecting the solar panel 10.

[0073] In order to solve the assembly problem of the limiting member 40 , a longitudinally distributed central axis 22 is provided inside the protective shell 21 , and the central axis 22 supports the limiting member 40 .

[0074] To further ensure the stability of the solar panel 10 after installation, Figure 2 , Figure 5 As shown, the photovoltaic assembly also includes a fixing member 50;

[0075] The fixing member 50 includes a frame 51, on which a lap joint 52 is provided. When the solar panel 10 is in a horizontal working state, the movable end of the solar panel 10 is placed on the lap joint 52. The setting of the lap joint 52 supports the movable end of the solar panel 10 and adds a supporting point to ensure the stability of the movable end of the solar panel 10 when it is in a horizontal working state (working state).

[0076] like Figure 2 , Figure 5 As shown, a cavity 53 is provided in the frame 51, and an arc rod 54 is provided inside the cavity 53. The arc rod 54 is slidably sleeved with an arc sleeve 55, and the arc rod 54 and the arc sleeve 55 are concentrically arranged; a gear 56 and a power part driving the gear 56 to rotate are provided inside the cavity 53, and the power part can be set as a motor with forward and reverse rotation, and the gear 56 is meshed with the gear teeth provided on the arc sleeve 55.

[0077] When the solar panel 10 is in a horizontal working state, the movable end of the solar panel 10 is placed on the overlapping portion 52, the motor is powered on and started, and the arc sleeve 55 is driven to rotate through the gear 56, until one end of the arc sleeve 55 extends to the outside of the cavity 53 and contacts the upper end surface of the solar panel 10, and the solar panel 10 is clamped and fixed by the arc sleeve 55 and the overlapping portion 52.

[0078] The fixing member 50 and the overlapping portion 52 in the present technical solution support the solar panel 10, and the arc sleeve 55 that is extended outwardly rotates contacts the upper end surface of the solar panel 10. The arc sleeve 55 and the overlapping portion 52 cooperate to clamp and fix the solar panel 10, thereby ensuring the position stability of the solar panel 10.

[0079] Furthermore, to ensure the power generation efficiency of photovoltaic modules, such as Figure 2 , Figure 6 As shown, the photovoltaic assembly further includes a cleaning member 60 ; the cleaning member 60 is provided to clean the photovoltaic assembly during the process of folding the photovoltaic assembly, thereby ensuring the cleanliness of the solar panel 10 , thereby ensuring the power generation effect of the solar panel 10 .

[0080] The cleaning part 60 includes a shell 61 assembled between the limit part 40 and the central axis 22. A unwinding roller 62, a winding roller 64, two supporting rollers 63 and a cleaning cloth 65 are arranged inside the shell 61. One end of the cleaning cloth 65 is connected to the unwinding roller 62, and the other end is connected to the winding roller 64 after passing through the two supporting rollers 63.

[0081] like Figure 6 As shown by the arrows in the figure, the unwinding roller 62 rotates to release the cleaning cloth 65, and the rewinding roller 64 rotates to rewind the cleaning cloth 65, so as to change the contact position between the cleaning cloth 65 and the plate body 11. The two supporting rollers 63 support the cleaning cloth 65, respectively corresponding to the two plate bodies 11, and the two sides of the cleaning cloth 65 are in contact with the two plate bodies 11 respectively.

[0082] like Fig. 9 As shown, the solar panels 10 are in a vertical relative distribution state. During the process of moving in the up and down directions, the solar panels 10 are in contact with the cleaning cloth 65, that is, the solar panels 10 are cleaned twice during the process of being retracted and released. At the same time, the solar panels 10 are in a vertical relative distribution state, so that the solar panels 10 are always in contact with the cleaning cloth 65 to ensure the cleaning effect.

[0083] To realize the rotation setting of the unwinding roller 62 and the winding roller 64, as shown in FIG. Figure 6 As shown, a power component is disposed inside the housing 61 to drive the unwinding roller 62 and the winding roller 64 to rotate.

[0084] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
