Sealing type screen door device

Abstract

The present invention relates to a sealing type screen door device, wherein a screen door is provided so as to be encompassed by a door of a train entering a station building, and an adsorption means is provided at the screen door so as to allow the screen door to be completely sealed and fixed to the body of the train, thereby completely blocking a change in air pressure (pressure wave) generated by the entering of the train so as to prevent the inflow of pressure waves into the station building. According to the present invention, the screen door device comprises: a sliding unit provided at a screen so as to cover a screen door; and an adsorption unit provided at the sliding unit so as to be adsorbed on an outer surface of a train.

1 . A sealing type screen door device comprising;
 a sliding unit provided on a screen so as to cover a screen door; and   an adsorption unit provided at the sliding unit so as to be adsorbed on an outer surface of a train.   
     
     
         2 . The sealing type screen door device of  claim 1 , wherein the sliding unit includes a sliding member having a passageway formed at a center portion thereof and an installation space formed at an interior side of a front edge thereof. 
     
     
         3 . The sealing type screen door device of  claim 2 , wherein the sliding member further includes an airtightness maintaining member provided at an open rim of the installation space. 
     
     
         4 . The sealing type screen door device of  claim 2 , wherein the sliding member has a first inlet formed therein to allow the air to be supplied to and exhausted from the installation space and a pressurization device supplying and exhausting the air through the first inlet. 
     
     
         5 . The sealing type screen door device of  claim 4 , further comprising a filter provided between the pressurization device and the first inlet. 
     
     
         6 . The sealing type screen door device of  claim 4 , wherein the plurality of first inlets and the plurality of pressurization devices are provided on the sliding member. 
     
     
         7 . The sealing type screen door device of  claim 2 , wherein the adsorption unit includes a fixing member positioned in the installation space of the sliding member of the sliding unit and having a second inlet formed therein, the adsorption is provided with a vacuum pump connected to the second inlet to supply and exhaust the air. 
     
     
         8 . The sealing type screen door device of  claim 7 , further comprising a filter provided between the vacuum pump and the second inlet. 
     
     
         9 . The sealing type screen door device of  claim 7 , wherein a plurality of second inlets and a plurality of the vacuum pumps are provided. 
     
     
         10 . The sealing type screen door device of  claim 7 , wherein the fixing member has an adsorption member provided at an end thereof. 
     
     
         11 . The sealing type screen door device of  claim 10 , wherein the adsorption member provided on the fixing member is separated from the fixing member. 
     
     
         12 . The sealing type screen door device of  claim 2 , wherein the sliding unit is formed in the shape of a rectangular tube. 
     
     
         13 . The sealing type screen door device of  claim 7 , wherein the sliding unit is formed in the shape of a rectangular tube. 
     
     
         14 . The sealing type screen door device of  claim 7 , wherein the sliding member further includes an airtightness maintaining member provided at an open rim of the installation space. 
     
     
         15 . The sealing type screen door device of  claim 7 , wherein the sliding member has a first inlet formed therein to allow the air to be supplied to and exhausted from the installation space and a pressurization device supplying and exhausting the air through the first inlet.
