This is a clean and renewable energy solution, usually using energy storage devices to convert and store energy from solar energy for later use.

[0003] In traditional photovoltaic energy storage devices, solar panels (photovoltaic panels) are located on the top of the device to capture sunlight and convert it into electrical energy. Photovoltaic panels are usually composed of multiple solar cells, which convert solar energy into electric current through the photon effect. The energy storage system is the part that stores the electrical energy converted from solar energy.

[0024] Specifically, the starting motor 1 3 drives the worm 5 to rotate, and the worm 5 meshes with the worm wheel 9, so that the worm wheel 9 rotates in the connecting frame 8. The side wall of the connecting frame 8 is connected to the fixed plate 10, and the fixed plate 10 can rotate accordingly, thereby changing the horizontal angle of the photovoltaic panel. At the same time, the starting motor 2 6 drives the connecting column 7 to rotate, and the top of the connecting column 7 is connected to the connecting frame 8. Through this structure, the vertical angle of the photovoltaic panel can be adjusted. This multi-angle adjustment design enables the photovoltaic system to maintain efficient operation under different sunlight conditions to obtain the best light angle, thereby maximizing the absorption of solar energy.

[0025] Reference Figure 3The opening and closing component includes a warehouse platform 11, which is fixedly connected to the side wall of the base 1. A plurality of connecting plates 12 are fixedly connected to the side wall of the warehouse platform 11. A top plate 13 is fixedly connected to the top of the connecting plate 12. A cylinder 14 is fixedly connected to the bottom of the top plate 13. An output plate 15 is fixedly connected to the output end of the cylinder 14. A straight groove 18 is provided inside the connecting plate 12. Side plates 16 are fixedly connected on both sides of the output plate 15. A plurality of pulleys 17 are rotatably connected to the side wall of the side plate 16. The outer wall of the pulley 17 is slidably connected to the inside of the straight groove 18. A plurality of connecting rods 19 are rotatably connected to the side wall of the pulley 17. One end of each connecting rod 19 is rotatably connected to a pull platform 20.

This structure realizes multi-angle adjustment of the photovoltaic panel, and can absorb solar energy to the maximum extent according to the lighting conditions, thereby improving the efficiency of this device. Energy storage efficiency. When it is necessary to open the internal space of the device to take out the internal battery, start the cylinder 14. The cylinder 14 outputs a push-pull force on the output plate 15 at the bottom of the top plate 13 to drive the output plate 15 to move vertically. The side plates 16 at both ends of the output plate 15 are pulled, and the side plates 16 can move vertically smoothly through the sliding of the pulley 17 in the straight groove 18. At this time, multiple connecting rods 19 on the side walls of the side plates 16 rotate inside the pull table 20 and change the inclination angle. After the pull table 20 is subjected to force, the bin cover 21 can be pulled to slide out from the inside of the bin table 11, thereby realizing the rapid opening and closing of the internal space of the device and improving maintenance efficiency.
