Grating type metro platform screen door climate switching device

Abstract

The invention belongs to the technical field of ventilation equipment, and particularly relates to a grating type metro platform screen door climate switching device. The grating type metro platform screen door climate switching device comprises an air valve body, a grating panel assembled on an air outlet of the air valve body and a temperature compensation and control mechanism used for temperature compensation and intelligent control. According to the grating type metro platform screen door climate switching device, through adopting a grating structure, ventilation can be more uniform, andmeanwhile a decoration effect can be achieved; furthermore, environment temperature of a station can be monitored in real time, and cold air and hot air can be provided in a self-adaptive mode according to different environment temperatures, so that experience feeling of passengers is better; in addition, more energy is saved, sound energy can be weakened to a great extent, and the purpose of noise elimination is achieved through layer-by-layer weakening of noise sound waves, so that a comfortable waiting environment is provided while air is ventilated; and finally, the concentration of carbondioxide in station environment can be monitored in real time, and an alarm is given when the concentration of carbon dioxide reaches the maximum value, so that workers is capable of conveniently adjusting the working condition of a public area in time, the air quality of the station is always in a good state, and physical and psychological health of the passengers is facilitated.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment, in particular to a climate conversion device for a grid-type subway screen door. Background technique [0002] The subway screen door is a high-tech product integrating construction, machinery, materials, electronics and information, and is used on subway platforms. The screen door separates the platform from the train running area, and is automatically opened by the control system. Subway screen doors are divided into closed type, open type and half-height type. Among them, the open type and half-height type are usually called "safety doors", which only play the role of safety and beauty. The closed type is usually called "screen door", and it is also the most commonly used one. [0003] In order to ensure the ventilation effect of the subway platform, a climate conversion device is usually installed on the top of the screen door to circulate the air and provide a comfortable wai...

Problems solved by technology

[0008] Aiming at the deficiencies in the prior art, the present invention provides a grid-type subway screen door climate conversion device, which solves the problem that the existing subway screen door climate conversion device has a single structure, poor ventilation uniformity, and insufficient functionality. Adaptive cold and hot air supply for different ambient temperatures on the platform, the passenger experience is not good, and there is no sound attenuation effect. Due to the serious noise pollution caused by train traffic, the discomfort caused to passengers is aggravated.
