Abstract

The invention relates to a door capable of automatically draining indoor flood. The door comprises a pass door having a door frame, a door leaf, a door closer, a handle lock and hinges. The bottom of the door leaf is provided with a flood discharge door. The flood discharge door comprises a flood discharge door leaf and a flood discharge door frame. The flood discharge door leaf is hinged onto the flood discharge door frame by means of flood discharge door hinges. The bottom of the flood discharge door leaf is provided with a hidden door closer. A flood discharge actuator is arranged on the flood discharge door leaf and comprises a metal floating ball, a connecting rod and a lock tongue. When indoor water level rises to the metal floating ball at one end of the connecting rod, the metal floating ball upwardly floats. The lock tongue at the other end of the connecting rod is separated from a fixing block. The flood discharge door leaf is opened up under effect of water pressure for discharging flood. After discharging flood, the flood discharge door leaf restores to an initial position under effect of the hidden door closer. The lock tongue has an oblique plane where the fixing block can slide under the effect of restoring force of the flood discharge door leaf and the flood discharge door leaf is fixed.

Description

technical field [0001] The invention relates to a door capable of automatically discharging indoor flood, which is used for flood discharge in a nuclear power plant and belongs to the technical field of indoor flood discharge. Background technique [0002] The value of the equipment in the nuclear power plant is high. Once flooding occurs, it will cause great losses. The existing nuclear power plant is generally required to have a flood gate. The flood gate is generally an independently designed door located at a specific position in the nuclear power plant. Similar doors have immature technology and high design costs. Contents of the invention [0003] The technical problem to be solved by the present invention is that the development and design of the floodgate in the nuclear power plant building is still relatively backward in the prior art, and the design and development for this field is still very insufficient at present. In view of the fact that there is no similar...
