Description

Intelligent ventilation control device for subway train Technical Field The utility model relates to the technical field of subway train ventilation, in particular to an intelligent ventilation control device for a subway train. Background The subway ventilation system is a key facility for guaranteeing the air quality of underground space and the comfort level of passengers, mainly realizes air circulation in a mode of combining mechanical ventilation and natural ventilation, utilizes a piston wind effect (pushing airflow during train operation), an axial flow fan and a wind shaft structure to ventilate, is equipped with a smoke exhaust system to cope with emergency situations such as fire and the like, ensures that the temperature, the humidity and the concentration of harmful gases in a tunnel accord with safety standards, and is designed to comprehensively consider energy conservation and environmental protection, airflow organization uniformity and emergency requirements of sudden accidents. The patent discloses a ventilation system and a control method of a subway train, wherein a first air inlet pipe, a second air inlet pipe and an air supply pipe are arranged in a gap between an inner train shell and an outer train shell, so that the space between the inner train shell and the outer train shell is effectively utilized, an air conditioning component with larger weight is arranged at the bottom of the outer train shell, the gravity center of a train body is greatly reduced, the roof space of the train body is prevented from being occupied, the net height of the inner train shell can be further improved, and the daily overhaul and maintenance of a heat pump device, an air supply adjusting device and an air exhaust adjusting device of the air conditioning component are facilitated for train maintenance staff, and the train maintenance staff can conveniently clean a refrigerating air duct and a heating air duct so as to ensure the ventilation system of the subway train to supply air cleaning. In the prior art, the ventilation equipment is very important because the subway train is arranged underground. In the prior art, ventilation in the train is realized mainly by adopting a central air conditioner mode. However, the central air conditioner has a limited ventilation effect and expensive equipment, and requires additional power consumption during ventilation, so improvement is required. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides an intelligent ventilation control device for a subway train. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides an intelligent ventilation control device for subway train, includes the subway shell, still includes: The tunnel blast assembly comprises an air inlet box, a screen plate is installed on one side of the air inlet box in a covering mode, and a lower air opening is formed in the bottom of the air box. According to a further technical scheme, the air inlet box is of a trapezoid structure. According to a further technical scheme, a roof is arranged on one side of a lower air opening of the tunnel air blast assembly in a butt joint mode, and a hole site is arranged on a position, corresponding to the lower air opening, of the roof. Further technical scheme, tunnel blast subassembly still includes the butt joint and installs the gas box in air outlet one side down, and the both sides of gas box are provided with the bearing hole, and the internally mounted in bearing hole has the bearing.
