[0015] In order to better achieve the purpose of the present invention, the present invention also provides a method for prefabricating a modular electric energy box, comprising the following steps: Step 1: Fix the container body on the ground, lift another device, move the lower support bracket on the lower side of the container body of the upper device toward the locking assembly on the upper side of the lower container body, and push the sliding buckle back into the upper support square tube when the lower support bracket approaches the sliding buckle of the locking assembly. The sliding buckle moves toward the upper support square tube to drive the rack to move. The movement of the rack compresses the spring. When the lower support bracket moves to the lower side of the upper support square tube, the sliding buckle is not blocked by the lower support bracket at this time. The compressed spring recovers and pushes the sliding buckle back to the initial position. The sliding buckle is fixed between the lower support bracket and the container body, and the upper and lower container bodies are stacked and locked. Step 2: When the lithium battery of the energy storage device is to be taken, the height is adjusted by adjusting the scissor lift to take the lithium batteries of different heights. If the lithium battery to be taken is on the right side of the container body, the controller needs to be moved to the left side of the container body. If the lithium battery to be taken is on the left side of the container body, the controller does not need to be moved. All the lithium batteries in front of the adjacent position of the lithium battery to be taken are pushed toward the front of the container body. The movable plate on the lower side of the support base of all the lithium batteries in front of the adjacent position of the lithium battery to be taken is moved, so that the sliding rail moves away from the fixed rail, and the gas spring is stretched. At this time, a certain space appears on the right side of the lithium battery to be taken. The support base is rotated, and the rotation of the support base drives the lithium battery to rotate. The lithium battery rotates to the appropriate position, the buckle is opened, and the lithium battery is pulled out. Stop pushing all the lithium batteries in front of the adjacent position of the lithium battery to be taken, and the stretched gas spring recovers to push the lithium battery back to the initial position. Step 3: Move back and forth between the upper container body and the lower container body with the aid of the ladder and auxiliary rod of the up-and-down moving device; Step 4: When the equipment is started, the controller controls the energy storage unit and the power system to realize the storage and release of electric energy. At the same time, the controller controls the cooling fan of the heat dissipation device to start and extract the hot air in the container from the main louver vents, and the air with lower external temperature enters the container from the auxiliary louver vents to realize the cooling of the container. Step 5: When disassembling the stacked container bodies, use the Allen wrench to rotate the connecting rod. The rotation of the connecting rod drives the gear to rotate. The rotation of the gear drives the rack to move away from the lower support bracket. The spring is compressed and the sliding buckle leaves the lower support bracket and the container body. At this time, the upper container body can be lifted.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The free space in the container body is small. When the lithium battery of the energy storage device is to be taken out, if the lithium battery to be taken out is on the right side of the container body, the controller needs to be moved to the left side of the container body. If the lithium battery to be taken out is on the left side of the container body, the controller does not need to be moved. All the lithium batteries in front of the adjacent positions of the lithium battery to be taken out are pushed toward the front side of the container body. The movable plate on the lower side of the support base of all the lithium batteries in front of the adjacent positions of the lithium battery to be taken out moves, so that the sliding rail moves away from the fixed rail, and the gas spring is stretched. At this time, a certain space appears on the right side of the lithium battery to be taken out, and the support base is rotated. The rotation of the support base drives the lithium battery to rotate. The lithium battery rotates to a suitable position, the buckle is opened, the lithium battery is pulled out, and the pushing of all the lithium batteries in front of the adjacent positions of the lithium battery to be taken out is stopped. The stretched gas spring recovers and pushes the lithium battery back to the initial position, which is conducive to taking out the lithium battery in a small space, does not affect the taking and maintenance of the lithium battery, and increases the number of lithium batteries in the container body; 2. The height can be adjusted by adjusting the scissor lift, so that workers of different heights can inspect and maintain lithium batteries at all heights; 3. Lift the upper equipment and place it on the lower equipment. The lower support bracket on the lower side of the upper container body moves toward the locking assembly on the upper side of the lower container body. The lower support bracket approaches the sliding buckle of the locking assembly, and pushes the sliding buckle back into the upper support square tube. The sliding buckle moves toward the upper support square tube to drive the rack to move. The movement of the rack compresses the spring. When the lower support bracket moves to the lower side of the upper support square tube, the sliding buckle is not blocked by the lower support bracket at this time. The compressed spring recovers, pushing the sliding buckle back to the initial position. The sliding buckle is fixed between the lower support bracket and the container body, which is conducive to quickly locking the stacked container body. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting rod 82 rotates to drive the gear 87 to rotate. The gear 87 rotates to drive the rack 85 to move away from the lower support bracket 81. The spring 86 is compressed, and the sliding buckle 88 leaves the space between the lower support bracket 81 and the container body 1. At this time, the upper container body 1 can be lifted.

The lower support bracket (81) on the lower side of the container body (1) of the upper device moves toward the locking assembly on the upper side of the lower container body (1). The lower support bracket (81) approaches the sliding buckle (88) of the locking assembly, and the sliding buckle (88) is pushed back into the upper support square tube (83). The sliding buckle (88) moves toward the upper support square tube (83) to drive the rack (85) to move. The movement of the rack (85) causes the spring (86) to be compressed. When the lower support bracket (81) moves to the lower side of the upper support square tube (83), the sliding buckle (88) is not blocked by the lower support bracket (81), and the compressed spring (86) is restored, pushing the sliding buckle (88) back to the initial position.

Step 2: When the lithium battery (58) of the energy storage device is to be taken, the height is adjusted by adjusting the scissor lift (42) to take the lithium batteries (58) at different heights. If the lithium battery (58) to be taken is on the right side of the container body (1), the controller (6) needs to be moved to the left side of the container body (1). If the lithium battery (58) to be taken is on the left side of the container body (1), the controller (6) does not need to be moved. All the lithium batteries (58) in front of the adjacent position of the lithium battery (58) to be taken are pushed toward the front side of the container body (1). All the lithium batteries (58) in front of the adjacent position of the lithium battery (58) to be taken are The movable plate (53) at the lower side of the support base (57) moves, so that the sliding rail (55) moves in a direction away from the fixed rail (52), and the gas spring (56) is stretched. At this time, a certain space appears on the right side of the lithium battery (58) to be taken out, and the support base (57) is rotated. The rotation of the support base (57) drives the lithium battery (58) to rotate, and the lithium battery (58) is rotated to a suitable position. The buckle (59) is opened, and the lithium battery (58) is pulled out. The pushing of all lithium batteries (58) in front of the adjacent position of the lithium battery (58) to be taken out is stopped, and the stretched gas spring (56) is restored to push the lithium battery (58) back to the initial position; Step 3: With the assistance of the ladder (72) and the auxiliary rod (73) of the up-and-down moving device (7), the container moves back and forth between the upper container body (1) and the lower container body (1); Step 4: When the device is started, the controller (6) controls the energy storage unit and the power system to be dispatched to achieve the storage and release of electric energy. At the same time, the controller (6) controls the cooling fan (32) of the cooling device (3) to start and draw the hot air in the container body (1) from the main louver air outlet (31), and the air with a lower external temperature enters the container body (1) from the auxiliary louver air outlet (33), thereby achieving cooling inside the container body (1); Step 5: When the stacked container bodies (1) are to be disassembled, the connecting rod (82) is rotated by an inner hexagonal wrench. The connecting rod (82) rotates to drive the gear (87). The gear (87) rotates to drive the rack (85) to move away from the lower support bracket (81). The spring (86) is compressed, and the sliding buckle (88) leaves the space between the lower support bracket (81) and the container body (1). At this time, the upper container body (1) can be lifted.
