[0017] The present invention is further described in detail below in conjunction with the accompanying drawings, tables and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] The present invention is further described below by way of examples, but is not limited to the following embodiments.

[0019] Example 1

[0020] like Figure 1 As shown, the large-capacity and easily retractable photovoltaic energy storage container power station of the present invention comprises a photovoltaic storage container, wherein the photovoltaic storage container 1 is provided with an energy storage system and a photovoltaic power generation system.

[0021] Combination Figures 2 to 4 The photovoltaic power generation system includes a folding device 6, a track 7, a photovoltaic folding bracket 4, a photovoltaic module 5 and a photovoltaic inverter. The track 7 is arranged on the outside of the photovoltaic storage container 1. The photovoltaic folding bracket 4 can be slidably arranged on the track 7. The photovoltaic module 5 is arranged on the photovoltaic folding bracket 4. The photovoltaic module 5 is connected to the energy storage system and the EMS energy management system respectively through the photovoltaic inverter, and the photovoltaic folding bracket 4 is connected to the folding device 6.

[0022] The photovoltaic power generation system is used to convert solar light energy into electrical energy, the energy storage system is used to store the converted electrical energy, and the photovoltaic storage container 1 is used as a carrier to assemble the photovoltaic power generation system and the energy storage system.

[0023] During the day, the photovoltaic power generation system converts the light energy generated by the sun into electrical energy. The electrical energy converted by the photovoltaic power generation system has two destinations: on the one hand, it is used to supply electricity for the well team's daily needs; on the other hand, it provides electrical energy for the energy storage system and stores the electrical energy in the energy storage system.

[0024] During the day, the photovoltaic power generation system converts energy. On the one hand, it converts light energy into electrical energy and directly supplies it to the load. On the other hand, at noon, the photovoltaic power generation is higher than the load power consumption. The excess power will be stored in the energy storage system. When the photovoltaic power generation system generates less power than the load power consumption or at night, it will be supplied to the load.

[0025] Solar photovoltaic power generation is based on the photovoltaic effect of semiconductors, using solar cells to directly convert solar energy into DC power. This system uses off-grid photovoltaic power generation, mainly composed of photovoltaic modules and inverters.

[0026] The power generation system composed of a photovoltaic power generation system and the energy storage device composed of energy storage elements form the two major parts of the system. By connecting to the off-grid photovoltaic system, the intelligent microgrid management system (EMS) monitors all loads in the living area in real time. When the power generation of the photovoltaic power generation system is greater than the power consumption, the battery energy storage device stores energy. When the power generation of the photovoltaic power generation system is less than the power consumption or at night, the battery energy storage device releases energy, thereby using the energy storage system to power the loads in the living area.

[0027] In the transport state, multiple groups of photovoltaic modules 5 are installed on the folding photovoltaic support 4 and are retracted into a folded state through the multi-stage steel wire rope 8, and stored in the light storage container 1; in the working state, the telescopic support 10 with a chassis is installed on the track 7 on the open space on both sides of the light storage container 1. The chassis of the telescopic support 10 has a ground screw hole, and the ground screw can be hammered into the ground to increase the wind resistance of the entire device. Then the track 7 is arranged at a suitable position on the open space on both sides, and the height of each telescopic support 10 is adjusted so that the folding photovoltaic support 4 forms an angle with the ground, and is in a downhill shape with the light storage container 1, so that the roller 9 on the folding photovoltaic support 4 is convenient for running and unfolding. The photovoltaic module 5 is installed on the folding photovoltaic support 4, and the length of the multiple groups of steel wire ropes 8 is adjusted by the retracting device 6 to adjust the angle of the photovoltaic module to be in an unfolded state. According to the lighting conditions of each work location, the photovoltaic module 5 is adjusted to a suitable angle to maximize the power generation efficiency of the photovoltaic power generation system. The entire system includes an easily retractable photovoltaic power generation system and energy storage system; the entire equipment is installed in a special container, and the entire system manages energy allocation through the EMS energy management system.

[0028] Example 2

[0030] The photovoltaic folding bracket 4 is connected with a steel wire rope 8 ; the retracting and releasing device 6 includes a motor, and one end of the steel wire rope 8 is wound around the driving end of the motor; two adjacent photovoltaic folding brackets 4 are also connected by the steel wire rope 8 .

[0031] The driving motor can ensure that the steel wire rope 8 pulls the photovoltaic folding bracket 4 to move by controlling the forward and reverse rotation of the motor, so that multiple photovoltaic folding brackets 4 are folded and the angle is adjusted.

[0032] Example 3

[0033] like Figure 5 As shown, different from Example 1, in the large-capacity and easily retractable photovoltaic energy storage container power station of the present invention, between two adjacent photovoltaic folding brackets 4, a positioning ruler 11 is provided on one photovoltaic folding bracket 4, and a plurality of teeth are provided on the lower side of the positioning ruler 11, and a positioning pin 12 is provided on the other photovoltaic folding bracket 4.

[0034] The photovoltaic module 5 is adjusted to a suitable angle, and the angle of the photovoltaic module 5 is fixed by the positioning ruler 11 and the positioning pin 12, so that the photovoltaic power generation system has the highest power generation efficiency.

[0035] The present invention manages the allocation of energy through the EMS energy management system, and folds and arranges the photovoltaic components through the container system. When in use, unfold the folded photovoltaic component array, the photovoltaic system starts to generate electricity, the photovoltaic power generation system is used to supply power during the day, and the energy storage system is charged during the peak power generation period of the photovoltaic power generation system, and the energy storage system is used to supply power when there is insufficient light and at night. First, it reduces the configuration of diesel generators and reduces investment costs; second, the foldable design of the container meets user needs and improves efficiency in moving; third, it saves energy and reduces carbon emissions, making it more environmentally friendly and more environmentally friendly.
