They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] Example:

[0027] Please see Figure 1-6 The present invention provides a technical solution:

[0028] A portable photovoltaic lithium battery energy storage and power generation device includes a carrying case 1. The left and right ends of the upper side of the carrying case 1 are provided with strip-shaped cavities. The left and right ends of the carrying case 1 are fixed with lifting mechanisms. The upper ends of the two lifting mechanisms are fixed with symmetrical U-shaped blocks 2. The symmetrical U-shaped blocks 2 are rotatably connected to the mounting plate 3 by a pivot pin. The mounting plate 3 is fixed with a solar panel 4. The front and rear sides of the mounting plate 3 are provided with limit mechanisms. When the solar panel 4 is damaged after long-term use, it can be disassembled and replaced. When not in use, it can be stored inside the carrying case 1. When needed, it can be moved out from inside the carrying case 1 and rotated to a horizontal position to facilitate receiving sunlight.

[0029] The bottom of the carrying case 1 is fixed with a base plate 5 by bolts. The top of the base plate 5 is fixed with a mounting bracket 6 by bolts. The top of the base plate 5 is fixed with a storage battery 7 by the mounting bracket 6. The top of the mounting bracket 6 is fixed with a power conversion device 8. The top of the power conversion device 8 is fixed with a controller 9. The solar panel 4 is electrically connected to the storage battery 7 through the power conversion device 8 and the controller 9. The specific working principle of this part is the prior art in this application, so it is not described in detail in this application.

[0030] The lifting mechanism includes a lead screw 10. The lower end of the lead screw 10 is rotatably connected to the lower end of the inner wall of the carrying case 1 via a bearing. The upper end of the lead screw 10 extends to the upper end of the carrying case 1 and is fixed with a rotating handle 11. The lifting plate 12 is threadedly connected to the rod wall of the lead screw 10. The side wall of the lifting plate 12 is slidably connected to the inner wall of the carrying case 1. The lower side of the U-shaped block 2 is fixedly connected to the upper side of the lifting plate 12. By rotating the rotating handle 11, the rotating handle 11 drives the lead screw 10 to rotate. The lead screw 10 drives the lifting plate 12, which is threadedly connected to the rod wall, to move. The lifting plate 12 drives the mounting plate 3 on the side wall and the solar panel 4 to move.

[0031] The limiting mechanism includes a limiting rod 13, which is fixedly connected to the side wall of the mounting plate 3. A first limiting block 14 is fixed to the other end of the limiting rod 13. A first moving rod 15 is slidably connected to the outside of the limiting rod 13. A square insert rod 16 is fixed to the side wall of the first moving rod 15. A square slot is opened on the side wall of the U-shaped block 2. The other end of the square insert rod 16 is inserted into the square slot. A first spring 17 is sleeved on the outside of the limiting rod 13. One end of the first spring 17 is fixedly connected to the side wall of the mounting plate 3. The other end of the first spring 17 is fixedly connected to the side wall of the first moving rod 15. Regardless of whether the solar panel 4 is in a vertical or horizontal state, the limiting mechanism is needed to limit and fix the mounting plate 3 and the U-shaped block 2.

[0032] The front and rear sides of the mounting plate 3 are threaded with symmetrical fastening bolts. The other end of the fastening bolts is engaged with the side wall of the solar panel 4. A sealing plate 18 is fixed on the upper side of the mounting plate 3. A sealing strip 19 is fixed on the side wall of the sealing plate 18. The side wall of the sealing strip 19 contacts the inner wall of the strip cavity. When the solar panel 4 needs to be replaced, the fastening bolts can be removed directly to replace it. When the sealing plate 18 is moved into the inside of the strip cavity, the sealing effect between the cavity and the sealing plate 18 can be ensured by the sealing strip 19.

[0033] The carrying case 1 has a first support plate 20 fixed on its left and right sides. A second support plate 21 is slidably connected inside the first support plate 20. A symmetrical first support base 22 is fixed on the lower side of the second support plate 21. A fastening bolt is threaded to the side wall of the first support plate 20. One end of the fastening bolt extends into the interior of the first support plate 20 and engages with the second support plate 21. A symmetrical second support base 23 is fixed on the lower left and right ends of the carrying case 1. During use, the second support plate 21 needs to be moved out from inside the first support plate 20 to support the entire power generation device.

[0034] A wiping mechanism is fixed to the upper part of the inside of the carrying case 1. The wiping mechanism includes a strip plate 24. The upper side of the strip plate 24 is fixedly connected to the upper part of the inner wall of the carrying case 1. Cavities are opened at the left and right ends of the inside of the strip plate 24. A moving block 25 is slidably connected inside the cavity. A second spring 26 is fixed to one side of the moving block 25. The other end of the second spring 26 is fixedly connected to the inner wall of the cavity. A second moving rod 27 is fixed to the side of the moving block 25 away from the second spring 26. The second moving rod 27 is slidably connected to the side wall of the strip plate 24. A wiping cotton strip 28 is fixed to one end of the second moving rod 27 that extends to the outside of the strip plate 24. The wiping cotton strip 28 contacts the side wall of the solar panel 4. After use, when the mounting plate 3 moves the solar panel 4 from the outside to the inside of the carrying case 1, the wiping cotton strip 28 can contact the side wall of the solar panel 4 to wipe the dust on its surface, so as to avoid excessive accumulation of dust on the surface and affect its photoelectric conversion.

[0035] A symmetrical first limiting plate 29 is fixed to the lower side of the strip plate 24. A second limiting block 30 is slidably connected inside the first limiting plate 29. A second limiting plate 31 is fixed to the lower side of the second limiting block 30. The second limiting plate 31 is slidably connected to the lower side of the first limiting plate 29. The lower side of the second limiting plate 31 is fixedly connected to the upper side of the mounting bracket 6. When it is necessary to plug the external power cord into the socket at the front end of the storage battery 7, the bottom plate 5 can be lowered. The bottom plate 5 drives the upper storage battery 7 to move to the lower end of the carrying case 1 and is limited by the first limiting plate 29, the second limiting plate 31 and the second limiting block 30.

[0036] Working principle:

[0037] When in use, carry the carrying case 1 to the location where power generation is needed, move the second support plate 21 inside the two first support plates 20, and support it by contacting the ground through the first support base 22 on the lower side of the second support plate 21. By rotating the rotating handle 11, the rotating handle 11 drives the lead screw 10 to rotate, and the lead screw 10 drives the lifting plate 12 connected to the rod wall threaded to move upward. The lifting plate 12 drives the U-shaped block 2, the mounting plate 3, and the solar panel 4 on the side wall to move to the outside of the carrying case 1.

[0038] The mounting plate 3 and solar panel 4 are rotated from a vertical position to a horizontal position, and the mounting plate 3 is fixed by the limiting mechanism. The limiting effect of the base plate 5 is released, and the base plate 5 drives the upper storage battery 7, power conversion device 8 and controller 9 to move downward until they move to the lower end of the carrying case 1. The solar panel 4, storage battery 7, power conversion device 8 and controller 9 are activated. Through their cooperation, they perform photoelectric conversion and store the energy inside the storage battery 7 for use.

[0039] After use, move the base plate 5, the energy storage battery 7, the power conversion device 8, and the controller 9 into the carrying case 1. Fix the base plate 5 to the carrying case 1 with the bolts on the side wall of the base plate 5. Rotate the mounting plate 3 and the solar panel 4 from horizontal to vertical and move them into the carrying case 1 again. During the movement, the wiping cotton strip 28 contacts the side wall of the solar panel 4 to wipe away the dust adhering to its side wall.
