Abstract

The invention relates to a flood-proof protection closed partition door. The flood-proof protection closed partition door comprises a door frame with grooves and a door leaf with convex heads. The grooves are provided with communicating holes, and glue plates used for sealing the communicating holes are arranged on the outer surface of the convex heads. The grooves are provided with bevel openingsformed in channels of the communicating holes, the glue plates are obliquely fixed to the convex heads, and the inclined angle of the plane on which the bevel openings are located is equal to that ofthe plane on which the glue plates are located to seal the bevel openings through the glue plates. According to the flood-proof protection closed partition door, the bevel openings are sealed throughthe inclined glue plates, only when the operation is in place, the glue plates are in contact with the grooves, the contact time is greatly shortened, and the possibility of the glue plate being damaged is greatly reduced.

Description

technical field [0001] The invention relates to an anti-flooding protection airtight partition door, more particularly to an anti-flooding protection airtight partition door. Background technique [0002] The layout of the drainage system in the subway section is related to the structure type of the ballast bed. For the integral ballast bed, it is generally the side row; for the special ballast bed, the middle row type is used. No matter what kind of drainage system is used, it is necessary to set a sealing mechanism on the partition door to realize the anti-flooding protection function. [0003] Such as figure 1 As shown, the anti-flooding protective airtight partition door of the side row form in the prior art includes a door frame 1' and a door leaf 2' that can move vertically downwards. Wherein, two grooves 11' are provided on both sides of the bottom end of the door frame 1', and the bottom end of the door leaf 2' is correspondingly provided with a male head 21' that...
