The rotation points of two adjacent rotating plates 2 are rotatably connected with self-rotating disks 3, and the self-rotating disks 3 are fixedly connected with fan blades 4. The conveyor belt 5 is in transmission cooperation with the plurality of self-rotating disks 3. The inner wall of the housing of the energy storage box 1 is movably cooperated with a plurality of movable plates 6 that drive the movable plates 2 to move.

The edge of the rotating disk 7 is rotatably connected with a pressure rod 8 that presses against the rotating plate 2. The pressure rod 8 cooperates with the movable part to pull the movable plate 6 to move.

[0037] A method for using an energy storage device for a power grid, using the above-mentioned energy storage device for a power grid, the specific method includes the following steps;

[0038] S1, start the motor 16 to make the rotating disc 3 and the fan blades 4 at the bottom rotate, and under the action of the conveyor belt 5, make the other rotating discs 3 and the fan blades 4 rotate, so as to ventilate and cool the energy storage box 1;

[0039] S2, the motor 16 rotates, driving the rotating disk 7 to rotate slowly, and under the action of the connecting plate 10, the movable plate 6 moves back and forth along the limit frame 9, so that the rotating plate 2 and the fan blades 4 at the top move back and forth up and down, and the rotating plates 2 and the fan blades 4 at the left and right sides move back and forth, thereby increasing the action range of the fan blades 4;

[0040] S3, the rotating disk 7 drives the pressing rod 8 to rotate, so that the pressing rod 8 acts on the two rotating plates 2 at the bottom with a gap, so that the two rotating plates 2 at the bottom can change their tilt angles adaptively, and the sliding frame 19 slides along the U-shaped plate 18, so that the multiple rotating plates 2 reciprocate with the output shaft of the motor 16 as the rotating shaft, switching the angle, and increasing the range of action of the multiple fan blades 4;

[0041] The self-adaptive function of the adjusting member ensures that the conveyor belt 5 is always in a straight state, so that the conveyor belt 5 and the rotating disk 3 are closely matched, ensuring that the multiple blades 4 always work synchronously and uninterruptedly;

[0042] In this application, if Figure 2 In the embodiment, a plurality of through holes are provided on the casing of the energy storage box 1, and a plurality of matching holes are also provided on the side of the casing of the energy storage box 1. The matching holes and the through holes cooperate with each other so that the rotating fan blades 4 replace the hot air in the energy storage box 1, so that the air flows and the cooling effect is ensured.

[0043] The movable part includes a limit frame 9 and a matching part that are movably sleeved with the movable plate 6. The limit frame 9 moves on the housing of the energy storage box 1 through the matching part. The middle part of the movable plate 6 is rotatably connected to the end of the rotating plate 2. The bottom of the movable plate 6 is rotatably connected to a connecting plate 10 connected to the pressing rod 8. The rotating plate 2 is provided with a fixed plate 11, one of the fixed plates 11 is provided with an adjusting part that cooperates with the movable rotating plate 2 to make the conveyor belt 5 closely fit the rotating disk 7, and a power part is provided at the position of the fan blade 4 below;

[0044] Under the action of the power component, multiple fan blades 4 rotate to perform ventilation, and at the same time, the rotating disk 7 rotates slowly. Under the action of the pressure rod 8, the connecting plate 10 rotates back and forth at a certain angle, and the movable plate 6 makes a relative reciprocating motion along the limit frame 9, driving the ends of the two rotating plates 2 on the top to reciprocate up and down, thereby changing the position of the fan blades 4 located at the top, and adjusting the position of the fan blades 4 located on both sides, thereby increasing the range of action of the fan blades 4 and ensuring the ventilation and cooling effect.

[0045] The adjusting member includes a slider 12, a sliding groove 13 slidably matched with the slider 12 is provided on the fixed plate 11, an adjusting rod 14 passing through the sliding groove 13 and connected and fixed to the rotating disk 3 is rotatably connected to the slider 12, and a compression spring 15 is hung between the slider 12 and the sliding groove 13;

[0046] When the movable plate 6 moves up and down, the spacing between the multiple fan blades 4 located at the upper and lower relative positions and the spacing between the multiple fan blades 4 located at the left and right relative positions are changed. At this time, in order to ensure that the conveyor belt 5 is always in contact with the rotating disk 3, the slider 12 is moved along the sliding groove 13 through the cooperation of the compression spring 15, driving the adjustment rod 14 and the fan blade 4 at this position to adjust the position. On the one hand, it helps to change the position of the fan blade 4, and on the other hand, it ensures that the conveyor belt 5 is always in contact with the rotating disk 3, so that the multiple fan blades 4 work, and ventilate and cool the energy storage cabinet.

[0047] The power part includes a motor 16 connected and fixed to the housing of the energy storage box 1, the output shaft of the motor 16 passes through the rotating plate 2 and is connected and fixed to the self-rotating disk 3 located at the bottom, and the self-rotating disk 3 and the fan blades 4 located at the bottom are driven to rotate by the operation of the motor 16, and the output shaft of the motor 16 will not affect the movement of the rotating plate 2;

[0048] The power member also includes a connecting disk 17 connected and fixed to the output shaft of the motor 16. The connecting disk 17 is meshed with the rotating disk 7 for transmission. The radius of the rotating disk 7 is larger than the radius of the connecting disk 17. When the motor 16 runs, the connecting disk 17 is driven to rotate rapidly, and the rotating disk 7 is driven to rotate at a low speed, thereby driving the movable plate 6 and the pressure rod 8 to move.

[0049] The rotating disk 7 and the connecting disk 17 preferably adopt a gear structure to ensure the meshing effect and the stability effect.

[0050] The matching part includes a U-shaped plate 18 connected and fixed to the housing of the energy storage box 1, a sliding frame 19 rotatably connected to the limit frame 9 is slidably matched in the middle of the U-shaped plate 18, and elastic compression parts 20 are hung and matched between the two sides of the sliding frame 19 and the U-shaped plate 18;

[0051] When the rotating disk 7 rotates, it drives the pressure rod 8 to rotate. The gap between the pressure rod 8 acts on the two rotating plates 2 at the bottom, so that the rotating plate 2 rotates back and forth and tilts with the output shaft of the motor 16 as the rotating axis. The other rotating plates 2 move adaptively (multiple rotating plates 2 form a parallelogram), and the sliding frame 19 moves along the U-shaped plate 18 (the elastic compression member 20 is used for resetting, so that the sliding frame 19 always has a tendency to reset to the middle of the U-shaped plate 18). At this time, the limit frame 9 rotates an angle on the sliding frame 19, and the movable plate 6 is in a tilted state, thereby increasing the activity area of ​​the fan blades 4 and ensuring the ventilation and cooling effect.

[0052] A brush plate 21 is fixedly connected to the connecting plate 10 (the brush plate 21 is distributed at an angle to facilitate dust falling into the ash box 22). The brush plate 21 cooperates with the through holes on the casing of the energy storage box 1. An ash box 22 is provided above the rotating disk 7. The reciprocating connecting plate 10 drives the brush plate 21 to reciprocate the through holes in the casing of the energy storage box 1 to avoid dust accumulation and affect the ventilation and cooling effect of the fan blades 4, and the scraped dust is collected by the ash box 22.
