Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to a drainage structure used in a high-multiplicity foam fire fighting system. Background Art

[0002] The main functions of a natural gas station are to receive natural gas, pressurize pipeline natural gas, distribute natural gas, distribute gas, and store gas for peak load regulation. In order to achieve the delivery of natural gas to villages and households, it is necessary to lay natural gas pipelines in mountainous areas and set up multiple natural gas stations along the way to achieve the transmission of natural gas. In natural gas stations, natural gas is generally stored in natural gas tanks and isolated by isolation walls. When a natural gas tank leaks, a high-multiplicity foam fire-fighting device is used to produce a large amount of water and foam mixture to flood the leakage area, thereby isolating the leakage point from the outside air and preventing the detonation of natural gas. Since the quality of fire fighting needs to be ensured, the foam produced by the high-multiplicity foam fire-fighting device is generally required to reach the height of the isolation wall. When the risk of natural gas leakage is handled, the water and foam mixture needs to be drained, and the existing drainage device generally takes the form of a canal. Since the canal is easily accumulated with debris such as leaves and plastic bags, the canal is blocked, thereby reducing the drainage efficiency of the water and foam mixture. Utility Model Content
