[0027] Reference Figure 1-Figure 2According to an embodiment of an energy storage cabinet for outdoor use of the utility model, the cabinet comprises a cabinet body 11, the upper side of the cabinet body 11 is connected to a fixed plate 12 through a bracket, the upper side of the fixed plate 12 is provided with two mounting plates 13 distributed front and back, a first rotating shaft 14 is rotatably connected between the mounting plates 13, and a movable plate 15 is fixed on the first rotating shaft 14, photovoltaic panels 16 are respectively installed in the fixed plate 12 and the movable plate 15, the movable plate 15 can be flipped to the upper side of the fixed plate 12 so that the two photovoltaic panels 16 are shielded, at which time the photovoltaic panels 16 do not work and are protected, and the movable plate 15 can be flipped to the right side of the fixed plate 12, at which time the two photovoltaic panels 16 are in an open state and can work;

[0028] In addition, when the photovoltaic panel 16 is in an open state, the movable panel 15 is flipped to the right side of the cabinet 11 and can serve as a sunshade.

[0029] In order to control the angle of the movable plate 15 relative to the fixed plate 12, the cabinet 11 is connected with a rack 18 through a lifting mechanism 101, and the No. 1 rotating shaft 14 is provided with a No. 1 gear 19 that can mesh with the rack 18, and the rack 18 is located on the right side of the No. 1 gear 19. When the rack 18 moves upward, the movable plate 15 will rotate counterclockwise under the action of the No. 1 gear 19 and the No. 1 rotating shaft 14 until it covers the fixed plate 12, so that the photovoltaic panel 16 is shielded. When the slide plate 17 and the rack 18 move downward, the movable plate 15 will rotate half a circle clockwise until it is supported. At this time, the photovoltaic panel 16 is in an open working state.

[0030] Furthermore, in order to ensure stable movement, two racks 18 are provided, which are distributed front and back. The first rotating shaft 14 extends to the front and back sides of the mounting plate 13 . Two first gears 19 are provided and are located on the front and back sides of the mounting plate 13 .

[0031] In the second embodiment of the energy storage cabinet for outdoor use, in order to enable the photovoltaic panel 16 to be wiped and avoid excessive dust on it, which will lead to a decrease in power generation, each of the mounting plates 13 is rotatably connected to a No. 2 rotating shaft 20, and the No. 2 rotating shaft 20 is located on the upper side of the No. 1 rotating shaft 14. The No. 2 rotating shaft 20 is equipped with a No. 2 gear 21 that can mesh with the rack 18. The left side of the mounting plate 13 is rotatably connected to a threaded shaft 22, and the threaded shaft 22 is connected to the No. 2 rotating shaft 20 on the same mounting plate 13 through a bevel gear set 23. A scraper 24 is commonly connected to the two threaded shafts 22, and the scraper 24 is used to scrape the photovoltaic panel 16. The upper and lower distance between the No. 1 rotating shaft 14 and the No. 2 rotating shaft 20 is not less than the length of the rack 18.

[0032] The specific operation process is:

[0033] In the initial state, the movable plate 15 extends to the right side of the cabinet 11 so that the two photovoltaic panels 16 are in working state. When the photovoltaic panel 16 needs to be protected, the rack 18 originally at the bottom moves upward. In this process, the rack 18 will mesh with the No. 1 gear 19 and drive the No. 1 gear 19 to rotate, and the movable plate 15 is turned over. The upper side of the fixed plate 12 is provided with a top plate 25, and the thickness of the top plate 25 is consistent with the thickness of the scraper 24. When the movable plate 15 turns over half a circle until it abuts against the top plate 25, the rack 18 is separated from the No. 1 gear 19 and is on the upper side of the No. 1 gear 19. At this time, the photovoltaic panel 16 is shielded, and the two photovoltaic panels 16 are attached to the scraper 24;

[0034] After that, the slide plate 17 continues to move upward so that the rack 18 engages with the second gear 21. At this time, the longitudinal movement of the rack 18 will pass through the bevel gear set 23 to cause the threaded shaft 22 to rotate, thereby driving the scraper 24 to move left and right. That is, when the rack 18 moves upward, the scraper 24 originally on the far right will move to the left, and when the rack 18 moves downward, the scraper 24 will move to the right. In this process, both photovoltaic panels 16 will be wiped by the scraper 24.

[0035] When the scraper 24 is at the far right and the second gear 21 is not engaged with the rack 18, in order to prevent the cabinet 11 from vibrating and causing the threaded shaft 22 to rotate and the scraper 24 to move freely, an elastic protrusion is provided on the upper side of the fixed plate 12 for positioning the scraper 24 at the far right, and the elastic protrusion will not affect the threaded shaft 22 being driven to rotate by the rack 18.

[0036] In order to prevent the scraper 24 from bending due to weight, a support plate 26 is provided on the upper side of the cabinet 11 , and the left end of the threaded shaft 22 is rotatably connected to the support plate 26 .

[0037] In an embodiment of the lifting mechanism 101, the lifting mechanism 101 includes a slide plate 28 provided on the cabinet 11, the rack 18 is attached to the left side of the slide plate 28 and can slide up and down, and a motor is provided in the cabinet 11, and the output shaft in the motor is connected to a lifting shaft threadedly connected to the rack 18, that is, the motor can drive the output shaft to rotate and thereby cause the rack 18 to move up and down.

[0038] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
