Openable-closeable ventilation device matched with urban rail transit platform safety door

Abstract

The invention discloses an openable-closeable ventilation device matched with an urban rail transit platform safety door. The openable-closeable ventilation device is arranged on the upper part of the platform safety door to form a closing state and a ventilating state for a platform rail interval. In order to improve a ventilation effect, the openable-closeable ventilation device is arranged in the door body of a platform fixed door. The openable-closeable ventilation device comprises a plurality of strip-shaped ventilation openings; a plurality of electric air valves are arranged in the ventilation openings; and ventilation shutters are arranged on the outside surfaces of the ventilation openings. The openable-closable ventilation device matched with the urban rail transit platform safety door has the advantages that: when air conditioners are used in summer, the closing state for the platform rail interval is formed by closing the electric air valves; and in non-air-conditioning seasons, the ventilating state is formed by opening the electric air valves. Therefore, by using the openable-closeable ventilation device, an effect of saving energy can be achieved in both air-conditioning seasons and non-air-conditioning seasons; the openable-closeable ventilation device is not only suitable to be used in the north, but also suitable to be used in the south; and a remarkable effect of saving the energy can be achieved when the openable-closeable ventilation device is used together with the urban rail transit platform door.

Description

technical field [0001] The invention relates to the technical field of subway safety doors, and relates to an openable and closable ventilation device matched with the safety doors of urban rail transit platforms. Background technique [0002] At present, urban rail transit platform safety door facilities are more commonly used in subways. It includes platform safety doors that separate subway lanes from platforms. In hotter regions abroad and in China, most of the subway stations built use screen doors between the subway lane and the platform to shield and separate the subway lane from the platform; the screen door can provide a more comfortable environment for the subway station platform. When the air conditioner is used in summer, it also saves energy for the operation of the ventilation and air conditioning system, because the screen door basically separates the space between the subway platform and the subway lanes on both sides, enclosing the platform into a small spac...

Problems solved by technology

The disadvantage is that the cooling load of the air conditioner in summer is also responsible for the heat dissipation of part of the tunnel area, so the power consumption of the air conditioner in summer is relatively high; in other times, it is more energy-saving. Taking the Beijing area as an example, calculations show that the ventilation and air-conditioning system with safety doors can save about 20% of electricity consumption throughout the year compared with screen doors.
