The subway station is constructed to ensure the quality of air in the station and the fire safety, and various ventilation equipment systems are arranged, wherein the subway platform door not only plays a role in protecting life safety, but also contributes greatly in the aspect of maintaining the hot environment in the station.
At present, a screen door system is generally adopted for subway platform doors in China, and when full-height screen doors are adopted, although physical isolation between a rail running area and a platform area is guaranteed, natural ventilation and air exchange are difficult to carry out on the internal space of a station by utilizing the piston action of a train. Therefore, some cities adopt a non-full-height platform door form, and aim to maximally utilize the piston effect of the train to introduce fresh air into the station in a transition season to ensure good air quality of the station, but the non-full-height platform door has a fatal defect, and a rail area and a platform area are spatially connected together due to the arrangement of the non-full-height platform door, so that a large amount of outdoor cold air can be introduced into the station by the piston effect generated by the train in a severe cold season, the temperature of the station is very low, and the phenomenon that the temperature of the station is abnormally severe and even a plurality of citizens complain about the station is too cold due to high wind speed in the station caused by the piston effect. In order to solve this problem, some researches have proposed to install an electric or manual air valve above the non-full-height platform door, and the practice has not been paid due to the complex control of FAS and BAS systems.

The unpowered movable blind window is simple in manufacturing process, but large in function, capable of obviously improving air quality and thermal comfort of a station, greatly reducing energy consumption of a ventilation and air conditioning system, solving the problem of supercooling of the station in severe cold seasons, and worthy of wide popularization.
Example 2
The embodiment provides a working method of a subway unpowered adjusting venetian blind, which specifically comprises the following steps:
s1, transition season working condition: the ventilation state passes through spacer pin 8 at ordinary times in transition season and fixes activity spacing stake 7 on shutter frame 1, and hinge 6 angle of expansion is 180, and the spacing route of angle of activity tripe 2 is opened, but the track district is with platform district wind pressure balance this moment, and the activity tripe is in the closed condition because of the fixed action of last torsional spring 4 and lower torsional spring. When subway trains enter the station, because of the powerful piston wind blowing pressure effect that the train produced, the interim wind pressure in rail row district is greater than the platform district far away, because of last axis of rotation 3 and lower axis of rotation setting are in 2 thirds of activity tripes department, so the activity tripe atress is different for activity tripe 2 opens to platform district direction, and opening angle can reach 60, thereby makes the outdoor new wind pressure that rail row district and piston wind shaft exchanged station district, like figure 3. After the train stops, the temporary high wind pressure in the rail running area is reduced, the wind pressure in the station area and the wind pressure in the rail running area gradually reach balance, and the movable louver 2 is restored to a closed state under the action of the torques of the upper torsion spring 4 and the lower torsion spring, as shown in fig. 4. And when the train leaves the station, similar with the entering station, the train can produce powerful piston wind suction effect, produces the negative pressure that is less than the platform district far away in the track district, and movable tripe 2 is opened to track district direction to take away the waste gas in platform district, discharge through the piston wind shaft, outdoor new trend will be followed station access & exit, station room, stair opening will be mended the platform district simultaneously, as figure 5.
S2, working condition in severe cold seasons: in cold seasons, due to the low outdoor temperature, if a large amount of fresh air is introduced into a station, the thermal environment inside the station is very poor, and therefore the piston effect of the train must be weakened. The movable limiting pile 7 turns 90 degrees towards the groove of the louver window frame 1 by using the hinge 6 through removing the action of the limiting pin 8, so that the movable limiting pile 7 completely seals the rotating path of the movable louver 2, the movable louver 2 keeps a closed state no matter how large the piston wind pressure between a rail area and a platform area is, at the moment, the device disclosed by the invention is matched with a non-full-height platform door to form a fully-closed shielding door system, as shown in figure 6, the rail area can be completely isolated from the platform area, and by combining a roundabout air valve and a piston air valve which are arranged at two ends of a subway ventilation system, the subway station can realize that the influence of a train piston effect is reduced to the maximum extent, and the thermal comfort degree in the station is improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
