Title:
水位差調整構造
Document Type and Number:
Japanese Patent JP7185917
Kind Code:
B2
Abstract:
To provide water level difference adjustment structure that makes opening/closing of the door for going back and forth the space not delay by adjusting the water level difference between two partitioned spaces.SOLUTION: The water level difference adjustment structure has: a partition for separating two space and restraining going back and forth of water between two spaces; a door that is included in the partition and opens to one space side, and that does not open due to water pressure of water existing in the one space side when a water level of the one space side becomes higher than a predefined height; first water level detection means for detecting the fact that the one space side water level reaches a first height; and a first apparatus that is included in the partition, and that prevents water inflow from the one space side to the other side when not detecting the fact that the one space side water level reaches the first height by the first water level detection means and makes water of the one space side flow into the other space side when the one space side water level becomes the first height.SELECTED DRAWING: Figure 1
