Description

Technical Field

[0001] This utility model relates to the field of energy storage boxes, specifically a long-lasting fireproof partition for energy storage boxes. Background Technology

[0002] Energy storage systems are characterized by long combustion times and high temperatures after thermal runaway, which poses a significant safety hazard to the surrounding environment. This could lead to more energy storage products experiencing thermal runaway, affecting public safety and the personal safety of maintenance personnel, resulting in substantial economic and property losses. Current energy storage boxes (containers or sheet metal cabinets) only have a certain density of insulating rock wool or rock wool sandwich panels inside the door panels and other surface sealing structures. When the temperature is high, the rock wool will ignite and burn, damaging the box frame structure. The heat inside the box will leak out, causing other nearby energy storage boxes or the surrounding environment to catch fire, posing a great risk to the surrounding environment. Utility Model Content

[0003] The purpose of this utility model is to provide a long-lasting fireproof partition for energy storage boxes, which can prevent the fire inside the energy storage box from overflowing for a longer period of time, giving on-site personnel more reaction time to extinguish the fire or prevent the fire from spreading.

[0004] The technical solution adopted in this utility model is as follows: it includes a steel plate one, a steel plate two, heat insulation material A, and heat insulation material B; heat insulation material A and heat insulation material B are disposed between steel plate one and steel plate two, and are arranged in the order of steel plate one, heat insulation material A, heat insulation material B, and steel plate two; steel plate one and heat insulation material A, heat insulation material A and heat insulation material B, and heat insulation material B and steel plate two are respectively bonded together by adhesive layers; the heat insulation material A and heat insulation material B are sealed between steel plate one and steel plate two by welding steel strips around the perimeter of steel plate one and steel plate two; heat insulation material A is made of ceramic fiber composite material.

[0005] Furthermore, a second layer of insulation material A is provided between the insulation material B and the steel plate; the insulation material A has adhesive layers on both sides for bonding and connecting with the insulation material B and the steel plate respectively; the insulation materials A and A can achieve better insulation effect.

[0006] Furthermore, the ceramic fiber composite material of the heat insulation material A includes a ceramicizable polymer layer and a mica tape. The ceramicizable polymer layer is uniformly coated and adhered within the two mica tapes. The ceramicizable polymer layer will only be heated and hardened at high temperatures to provide fire resistance. Normally, the ceramic fiber composite material is within the flexible mica tape, so there is no need to worry about impact or vibration.

[0007] Furthermore, the first steel plate is a bent steel plate, the second steel plate is a corrugated steel plate, and the steel bar is either a square tube or an I-beam. The first steel plate is located close to the heat source and inside the energy storage box; the second steel plate is located away from the heat source and outside the energy storage box.

[0008] Furthermore, the thickness of the bent steel plate is between 0.5 and 2 mm, and the thickness of the corrugated steel plate is between 0.5 and 2 mm.

[0009] Furthermore, the heat insulation material B is made of rock wool, and the heat insulation material A2 is the same ceramic fiber composite material as heat insulation material A.

[0010] The adhesive layer is a fire-resistant adhesive, and the heat insulation material A and the steel plate are further reinforced by spot welding studs.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The heat insulation material A of this technology is made of ceramic fiber composite material and heat insulation material B rock wool material in combination. The ceramic fiber composite material of heat insulation material A includes a ceramicizable polymer layer and mica tape. The ceramicizable polymer layer is evenly coated and pasted into the mica tape. This makes the long-lasting fireproof partition not only resistant to daily vibration and collision during transportation, but also allows the ceramicizable polymer layer to ceramicize and provide long-lasting fire protection when high temperature is out of control.
