DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-8 , the utility model provides a technical solution:

[0024] A stacked energy storage device comprises an energy storage box 1 and a cover 2. The upper end of the energy storage box 1 is provided with the cover 2. The lower end of the energy storage box 1 is fixedly connected with a foot seat 3. The foot seat 3 is fixedly connected with a bolt 5 by installing a fixing plate 4. The lower end of the bolt 5 is fixedly connected with a fixing ring washer 6. The lower end of the fixing ring washer 6 is fixedly connected with a damper 7. The lower end of the damper 7 is fixedly connected with a shaft column 8. The inner side of one end of the shaft column 8 is rotatably connected with a side rotating column 9. The outer side of the side rotating column 9 is fixedly connected with a roller 10. The outer side of the side rotating column 9 is fixedly connected with a clamping rod 12. The clamping rod 12 is clamped in the inner side of a clamping hole 13. The clamping hole 13 is provided on the inner side of a protective shell 14. The inner side of the protective shell 14 is provided with a clamping groove 11. The inner side of the protective shell 14 is fixedly connected with a limited slider 15. The outer side of the limited slider 15 slides on the inner side of the limited groove 16. The inner side of the protective shell 14 is provided with an operating window 17.

[0025] There are four feet 3, and the number of mounting plates 4 is the same as that of the feet 3. The middle end of the mounting plate 4 is in the same vertical line as the feet 3. Four threaded holes are provided on the inner side of the feet 3 to facilitate the disassembly of the mounting plate 4, thereby facilitating the maintenance of the roller 10 and reducing the space occupied. The outer side of the bolt 5 is spirally fitted on the mounting plate 4 and the inner side of the feet 3. There are four groups of bolts 5, and each group of bolts 5 has four bolts, which can stabilize the mounting plate 4 at the lower end of the feet 3. The shape of the fixing ring washer 6 is cylindrical, and the center point of the upper end of the fixing ring washer 6 is aligned with the mounting plate 4. The middle ends are on the same vertical line, and the center point of the lower end of the fixed ring pad 6 and the upper end of the damper 7 are on the same vertical line, which has the effect of reducing shock to the energy storage box 1 and reducing damage to the equipment inside the energy storage box 1. The inner side of the protective shell 14 is hollow, and the protective shell 14 is sleeved on the outside of the shaft column 8. The shaft column 8 is divided into two cylindrical bodies, which are rotatably connected to each other. There are two card holes 13 in each group, and the shape of the card hole 13 is a cylindrical body. The outer side of the card rod 12 slides on the inner side of the card slide groove 11, which has the effect of protecting the shaft column 8 and is convenient for the protective shell 14 to be installed on the outside of the shaft column 8.

[0026] Working process: when the device is used and needs to be installed, the cover body 2 is opened, the installation fixing plate 4 is fixed to the lower end of the foot seat 3 by the bolt 5, and then the protective shell 14 is slid on the outside of the shaft column 8. When the protective shell 14 slides, the limiting slider 15 fixedly connected to the inner side of the protective shell 14 is slid on the inner side of the limiting slide groove 16 opened on the inner side of the shaft column 8, so as to limit the installation of the protective shell 14. At the same time, the clamping rod 12 fixedly connected to the outer side of the rotating column 9 slides on the inner side of the clamping slide groove 11. The clamping slide groove 11 facilitates the installation of the protective shell 14. At the same time, when the clamping rod 12 slides on the inner side of the clamping slide groove 11, the protective shell 14 undergoes a certain deformation. When the clamping rod 12 is aligned with the clamping hole 13, the clamping rod 12 is clamped on the inner side of the clamping hole 13, and the protective shell 14 restores its shape. At this time, the installation of the protective shell 14 can be completed. The protective shell 14 prevents external impact from damaging the shaft column 8 when the roller 10 is in use. When the energy storage box 1 is moved, the roller 10 rolls on the ground, and the roller 10 drives the shaft column 8 to rotate. When encountering a pothole, the damper 7 has the effect of absorbing shocks on the energy storage box 1, reducing damage to the equipment inside the energy storage box 1, and the operation window 17 is convenient for observing and maintaining the inside of the shaft column 8.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
