DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a large energy storage electric box, comprising: a box body 1, a plurality of support seats 2 are fixedly connected to the base of the box body 1, a frame 3 is fixedly connected to the support seat 2, four symmetrically distributed supporting plates 4 are slidably connected in the frame 3, and an energy storage battery 5 is arranged on the supporting plate 4, two first positioning blocks 12 are fixedly connected to the surface of the middle of the frame 3, and second positioning blocks 13 are rotatably connected to the two sides of the frame 3 at the horizontal position of the first positioning blocks 12, and a fixing column 14 is rotatably connected to the first positioning block 12 through the second positioning block 13, and a fixing column 14 is near the first positioning block 12. A fixing block 16 is fixedly connected to the side, and a spring 15 is fixedly connected to the outside of the fixing column 14 on one side of the fixing block 16. Four supporting plates 4 are slidably connected to the inside of the frame 3. The sliding supporting plate 4 can slide out from the inside of the frame 3 and place the energy storage battery 5 on the supporting plate 4. By rotating the second positioning block 13 to make it parallel to the first positioning block, and by pressing the handle on the fixing column 14 on one side of the second positioning block 13, the spring 15 is compressed, driving the fixing block 16 to clamp the energy storage battery 5. At the same time, the other end of the fixing column 14 is clamped on the first positioning block 12 to fix the energy storage battery 5.

[0021] The supporting plate 4 is a double-M-shaped hollow structure, which can help the energy storage battery 5 to better dissipate heat and ventilate.

[0022] Both sides of the box body 1 are symmetrically provided with air holes 6 distributed in a uniform linear array, the upper ends of the outer sides of the air holes 6 are fixedly connected with rain screens 7, and the inner sides of the air holes 6 are fixedly connected with rainproof curtains 8. A total of eight symmetrical air holes 6 are provided on both sides of the box body 1. When it is in bad weather outdoors, the external rain screens 7 can prevent other objects from entering the inside of the box body 1 through the air holes 6. When heavy rain enters the inside of the air holes 6 with the wind, the rainproof curtains 8 can block the rainwater outside without affecting the ventilation function of the air holes 6.

[0023] Bolts 9 are rotatably connected to one side of the supporting plate 4 on both sides of the frame 3, and fixing bolts 10 are fixedly connected to the bolts 9. Since the supporting plate 4 can be slid out from the frame 3, when the supporting plate 4 needs to be fixed on the frame 3, the fixing bolts 10 are driven by rotating the bolts 9 to contact and fix the supporting plate 4.

[0024] A rotating block 11 is rotatably connected to one side of the supporting plate 4 in the middle of the frame 3. When the supporting plate 4 needs to be fixed to the frame 3 for a second time, the rotating block 11 is rotated so that both sides of the supporting plate 4 are fixed, thereby increasing the stability of the entire device.

[0025] The top of the energy storage battery 5 is located on the frame 3 and is fixedly connected to a top plate 17, the bottom surface of the top plate 17 is fixedly connected to an electric hydraulic telescopic rod 18, and the end of the electric hydraulic telescopic rod 18 is fixedly connected to a fixed plate 19. When the energy storage battery 5 is placed on the supporting plate 4, the fixed plate 19 is adsorbed on the top surface of the energy storage battery 5 by adjusting the extension and contraction of the electric hydraulic telescopic rod 18, thereby providing all-round protection for the energy storage battery 5.

[0026] Working principle: When a large energy storage box is used, four supporting plates 4 are slidably connected inside the frame 3. The sliding supporting plates 4 can slide out from the inside of the frame 3 to place the energy storage battery 5 on the supporting plates 4. Since the supporting plates 4 can be slid and pulled out from the frame 3, when it is necessary to fix the supporting plates 4 on the frame 3, the fixing bolts 10 are driven by rotating the bolts 9 to contact and fix the supporting plates 4. When it is necessary to fix the supporting plates 4 on the frame 3 for a second time, the rotating block 11 is rotated so that both sides of the supporting plates 4 are fixed, thereby increasing the stability of the entire device. The second positioning block 13 is rotated to make it parallel to the first positioning block, and the second positioning block 13 is pressed on one side. The handle on the fixing column 14 and the spring 15 are compressed accordingly, driving the fixing block 16 to clamp the energy storage battery 5. At the same time, the other end of the fixing column 14 is clamped on the first positioning block 12 to fix the energy storage battery 5. When the energy storage battery 5 is placed on the supporting plate 4, the fixing plate 19 is adsorbed on the top surface of the energy storage battery 5 by adjusting the extension and contraction of the electric hydraulic telescopic rod 18, so as to provide all-round protection for the energy storage battery 5. The entire energy storage box can perform multiple fixations on the internal energy storage battery 5 to prevent the energy storage battery 5 from moving. Sufficient fixation of the battery assembly can not only ensure its safe operation, but also reduce the probability of failure. The entire device is highly practical.

[0027] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
