Noise elimination and ventilation type platform door

Abstract

The invention discloses a noise elimination and ventilation type platform door, and relates to the field of platform door systems. A base is arranged, the base and a cross beam at the upper portion of a platform door top box are fixedly installed, and a noise elimination gate air valve is installed on the base. A fixing plate is arranged at the upper portion of the noise elimination gate air valve, a mounting hole is formed in the fixing plate, the mounting hole is connected with a civil engineering beam through an anchor bolt, the noise elimination gate air valve is composed of noise elimination sections at the two ends and a gate section in the middle, a valve body outer frame is arranged to be of an integrated structure, and a gate moves up and down through an electric mechanism and a transmission mechanism. Communication or isolation between a rail-mounted area and a platform public area is achieved. The noise elimination gate air valve is installed on the platform door, opening and closing of the air valve can be adjusted according to outdoor conditions, and then the communication or isolation function of the rail-mounted area and the platform public area is achieved. When the gate ascends and train piston wind is used for ventilating a station, the noise elimination sections arranged in a segmented manner form an impedance composite sound eliminator, and noise generated by a train can be effectively controlled.

Description

technical field [0001] The disclosure of the present invention relates to the field of platform door systems, in particular to a noise-absorbing and ventilated platform door. Background technique [0002] my country has a vast territory, and all provinces and cities from south to north currently have subways in operation. For areas where the ventilation season is long and the public areas of the stations need to be equipped with air conditioners in summer or to prevent the temperature of the stations from being too low in winter and need to isolate the intervals and public areas, ventilation and closed areas should be set up. Convertible platform doors have great energy-saving implications. [0003] When the conversion device adopts the ordinary air valve structure, it will be impacted by the piston wind of the train for a long time when it is closed, resulting in a large amount of air leakage, which greatly increases the load of the air conditioner and increases the operatin...

Problems solved by technology

[0003] When the conversion device adopts the ordinary air valve structure, it will be impacted by the piston wind of the train for a long time when it is closed, resulting in a large amount of air leakage, which greatly increases the load of the air conditioner and increases the operating cost. At the same time, it increases the temperature fluctuation in the public area and affects the comfort of passengers. When it is opened, the noise of the train will be transmitted to the public area of ​​the station, affecting the passenger waiting experience
