LIQUID IMMERSION PREVENTION GATE

摘要

PROBLEM TO BE SOLVED: To provide a liquid immersion prevention gate which is interposed in an immersion prevention line for preventing immersion of water unexpectedly flowing out and liquid such as an organic solvent and can avoid a passage obstacle when a movable body such as a vehicle passes the immersion prevention line.SOLUTION: An inventive liquid immersion prevention gate (flood prevention gate G) includes a liquid stopping wall member (cut-off wall member 1) displaced to a first position for preventing immersion of liquid (water) and to a second position so that the liquid stopping wall member is pushed by a movable body M from the first position and the movable body M can pass. When the liquid stopping wall member is released from the pushing force of the movable body M, it is displaced from the second position to the first position by self-restitutive force thereof.
