Description

Technical Field

[0001] The utility model belongs to the field of fire protection technology, and more specifically, particularly relates to a fire protection system for energy storage box-type substations. Background Art

[0002] With the continuous development of new energy, energy storage devices are changing with each passing day. The market share of energy storage box-type substations using batteries as energy storage carriers has been increasing year by year. Since the battery is a high-energy carrier, chemical reactions can still occur and a large amount of heat can be released without oxygen, thus triggering a fire or explosion.

[0003] Currently, gas fire protection is mostly used in the market, such as heptafluoropropane, 1230 gas, etc., or high-pressure fine water mist fire protection. However, with the repeated reignition of faulty batteries and the continuous release of energy, gas or fine water mist fire protection cannot achieve a good fire protection effect and still cannot prevent the further spread of accidents. Water immersion fire protection is currently recognized as the best fire protection method for batteries in the world. In the stage of abnormal temperature or the initial stage of a fire, the battery is directly put into water and completely immersed to avoid the further deterioration of the accident. However, due to the limitation of the internal structure of the box-type substation, battery water fire protection cannot be well applied to energy storage devices.

[0004] After retrieval, the upper-level patent with the patent publication number CN210813611U discloses a fire protection system for energy storage box-type substations, including a prefabricated cabin body. A fire protection battery rack is arranged inside the prefabricated cabin body. A fire protection water tank is arranged below the bottom of the prefabricated cabin body. An anti-condensation isolation device separated from the fire protection water tank is arranged on one side of the bottom of the prefabricated cabin body where the fire protection battery rack is located. A corridor telescopic pedal device is arranged above the anti-condensation isolation device. An explosion-proof pressure relief device is arranged on the top of the prefabricated cabin body.

[0005] In the above-mentioned disclosed patent, the batteries on the battery rack can be pushed into the water through a certain device to quickly extinguish the fire. However, during the fire extinguishing process, the batteries need to be pushed into the water tank one by one, which is slow and difficult to recover from the water tank. Therefore, a fire protection system for energy storage box-type substations is designed to solve the above problems. Summary of the Utility Model
