The lithium battery 2 is provided on the mounting plate. A recovery frame 38 is provided below the mounting plate. The power cylinder 18 is installed on the energy storage cabinet 1. The sand in the storage bin 4 is recovered into the recovery frame 38 after the fire extinguishing work is completed.

By adjusting the adjusting bolt 29, the first support plate 21 positions the storage bin 4 at a corresponding height, keeping the bottom surface of the storage bin 4 in contact with the first fixed plate 5 and the second fixed plate 6, but the storage bin 4 will not be completely loaded on the first fixed plate 5 and the second fixed plate 6, so that the power cylinder 18 can more easily control the displacement of the sealing plate 7; similarly, each second load-bearing rod 20 in the second load-bearing rod layer is located directly above two adjacent first load-bearing rods 19 in the first load-bearing rod layer, and the width of the second load-bearing rod 20 is greater than the gap between the two adjacent first load-bearing rods 19, so that the sand in the storage bin 4 will be loaded on the first load-bearing rod 19 and the second load-bearing rod 20, thereby avoiding that all the sand is loaded on the sealing plate 7; after pressing down the first slider 34 so that the second slider 33 completely enters the second groove 32, one end of the first support plate 21 is installed in the first installation groove on the first limit seat 23, and the first slider 34 is loosened, which is convenient for installation.
