When any one of the first alarm button 3 and the second alarm button 7 is actuated due to misoperation of personnel or other reasons, a common alarm signal is sent to a monitoring room, and a person on duty arranges the personnel to carry out on-site recheck.
When a large amount of water leaks into the factory building due to pipeline burst or other reasons, the leaked water can flow to the self-flowing water drainage hole at the lowest part of the factory building firstly. At the moment, the water level outside the self-flowing drainage hole can be continuously raised along with the inflow of seepage water. After the water level rises to the height of the second locking rods 9, the floating balls 9-3 at the tail ends of the second locking rods 9 start to rotate around the second fixing shafts 8 under the action of the floating force, and as the two sets of secondary drainage systems are symmetrically arranged, the two second locking rods 9 are separated from the corresponding second locking grooves 10 simultaneously in the process of continuously rising the water level, so that the two sub door leaves 2-1 are opened. When the water leakage flow is not large, the sub door leaf 2-1 can quickly remove the water entering the plant after being opened and ensure that the water level cannot reach the position of the second alarm button 7; when the water leakage flow is larger than the overflow of the sub-door leaf 2-1 when the water level reaches the position of the second alarm button 7, the water level continuously rises, the 2 second locking rods 9 are all rotated to the vertical position to trigger the second alarm button 7, then a secondary alarm signal is sent to the monitoring room, and an alarm for evacuating the low point of the plant is sent to personnel in the plant. When the water level rises further to the level of the first locking bar 5, the first locking bar 5 will also be released from the first locking groove 6 by the buoyancy, thereby opening the main door leaf 2. At this moment, if the water leakage flow is less than the overflow of the main door leaf 2 when the water level reaches the position of the first alarm button 3, the first alarm button 3 will not be triggered, so a time interval can be set, and after the time interval, if the first alarm button 3 is not triggered, the on-site emergency repair work can be carried out by the personnel in the factory.
