The mounting box 3 and a protective cover 4 are positioned between the two support frames 5. The protective cover 4 is located on the top plate of the mounting box 3. A support plate 11 is slidably mounted inside the mounting box 3. The support plate 11 has multiple mounting holes for installing equipment from the energy storage power station. A sealing plate 301 is provided on the outside of the support plate 11. By using the sealing plate 301 to slide the support plate 11 into the mounting box 3, the equipment can be moved inside for storage. The protective cover 4 then descends to contact the mounting box 3. The protective cover 4, the mounting box 3, and the sealing plate 301 form a fireproof isolation chamber, which can safely isolate the internal energy storage power station equipment.

The connecting column 12 is elastically installed on the mounting box 3 through an elastic element. The elastic element pulls the connecting column 12 and the protective cover 4 downward by elastic force, so that when the mounting box 3 is in the initial position (at this time, the fixing column 15 is not in contact with the top plate 13), the protective cover 4 contacts the top of the mounting box 3 to seal the top of the mounting box 3. The guide rail 2 has a sliding groove 201 on its outside. Inside the sliding groove 201, a movable block 18 and a support block 17 are slidably arranged.

Figure 4The scissors structure shown, when the support block 17 is driven by external force and slides along the guide rail 2, the scissors structure expands or shrinks, which can drive the sliding block 14 to move in the guide groove 302, thereby controlling the movement of the fixed column 15. In normal use state: when the equipment (or counterweight block) is placed in the box 3 at the lowermost layer of the guide rail 2, the self-weight of the equipment drives the support block 17 to move downward along the guide rail 2, so that the two groups of support blocks 17 move away from each other, the scissors mechanism expands synchronously, the sliding block 14 is pushed by the hinge rod 221 to slide to the center along the guide groove 302, and the two groups of fixed columns 15 move close to each other and lift the top plate 13 upward, so that the protective cover 4 is lifted to the maximum opening, facilitating the equipment to be taken out and placed in, and the gap above the installation box 3 forms a convection heat dissipation channel, and the heat generated by the equipment during operation can be discharged outward; in isolation state: after the fire sensor is triggered, the driving mechanism drives the two groups of support blocks 17 to move towards each other, the scissors structure shrinks, the sliding block 14 drives the fixed column 15 to separate from the top plate 13, and the protective cover 4 seals the installation box 3 under the action of the elastic member, forming a fireproof isolation cabin, and multiple fireproof isolation cabins move close to each other, facilitating subsequent equipment disassembly and maintenance. The driving mechanism is arranged on the guide rail 2 and isolates the equipment by moving the multiple installation boxes 3 close to each other.

The energy storage device is fixed through the mounting holes of the support plate 11. Pushing the sealing plate 301 causes the support plate 11 to slide into the mounting box 3. The weight of the bottom mounting box 3 causes the support block 17 to move downwards along the guide rail 2. The scissor mechanism unfolds, and the fixing column 15 lifts the protective cover 4 to form a heat dissipation channel.
