Description
Technical field
The present invention relates to a kind of Ventilation device for bullet train.
Background technology
The air interchanger of existing motor-car is in motor-car operational process, if train is having under the pyrotechnics emergency state, entering of air interchanger outside air can cause pyrotechnics combustion case to aggravate.
The patent No. be 201020129718.8 patent discloses a kind of air changing device of high-speed railway, housing is provided with the new wind entrance be connected with new wind filtering installation, the new wind be connected with vehicle air conditioning unit exports, mouth is entered with vehicle useless that air exhausting duct is connected of giving up, and drain pipe overflow pipe, new wind fan and exhaust blower is provided with in housing, new wind fan and exhaust blower are driven by new wind turbine and exhaust motor respectively, the operating frequency of two motors is independently controlled by control unit, the pressure sensor for inspection vehicle external pressure is provided with in air interchanger, new wind entrance and drain pipe overflow pipe place are provided with temperature sensor, pressure sensor is connected with control unit signal with temperature sensor.Control unit in this air interchanger receives pressure change signal and new wind, the useless temperature information arranged of pressure sensor detection, controls respectively, reach the object of adjustment air quantity, realize the control of interior pressure the operating frequency implementation of new wind fan and exhaust blower.This type air interchanger technology is in motor-car operational process, and the motor in air interchanger is merely able to automatically carry out frequency adjustment according to motor-car running velocity, and the frequency that train can only set according to control unit in operational process provides intrinsic ventilation air quantity; If having under pyrotechnics state in train travelling process, and if air interchanger still can possess service conditions in the case, then still can continue provides air quantity to train, can not ensure the safety traffic of vehicle.
Summary of the invention
The object of the invention is to, for the deficiencies in the prior art, provide a kind of Ventilation device for bullet train, quantity-adjustable blast, and when running into pyrotechnics, isolated extraneous air enters in time, ensures the safe operation of motor-car.
Technical scheme of the present invention is, a kind of Ventilation device for bullet train, comprise housing, be provided with new wind entrance, the waste gas air draft entrance that new wind exports, the air exhausting duct that gives up with motor-car is connected be connected with motor-car air-conditioner set and waste gas wind exhausting outlet on the housing, described new wind entrance installs the air intake valve being regulated intake by air intake control cock, described waste gas wind exhausting outlet installs the valve for air exhaust being regulated waste gas exhaust air rate by air draft control cock, and described air intake control cock and air draft control cock are independently controlled by control unit respectively; Be provided with the smoke-detectors for smog in inspection vehicle in this air interchanger, described smoke-detectors is connected with described control unit.
Described air intake valve comprises the air feed shutter door on air intake valve body and air intake valve body, and described air intake control cock controls the folding of air feed shutter door.
Described valve for air exhaust comprises the air draft blind door on valve for air exhaust body and valve for air exhaust body, and air draft blind door can comprise one or more pieces blades, and can up and down or left-right rotation, and described air draft control cock controls the folding of air draft blind door.
Control unit can control air intake valve by air intake control cock, air draft control cock controls valve for air exhaust; And then regulate air feed shutter door and air draft blind door open size, regulate the airflow pressure of air interchanger; When run in train operation the emergency situation such as to catch fire time, smoke-detectors detects smog, signal is passed to control unit, and air feed shutter door and air draft blind door are closed completely, and air interchanger cuts out automatically, quits work; When smoke signal is removed, air feed shutter door and air draft blind door are opened, and air interchanger is resumed work.
Ventilation device for bullet train of the present invention, by setting up air intake valve and valve for air exhaust, for vehicle ventilation systems provides more windy amount demand; Under train has pyrotechnics state, the signal fed back by smoke detector, close air interchanger air intake valve and valve for air exhaust, isolated extraneous air enters, for train provides important safety control.
