Abstract
A self-adjusting ventilating system relates to the field of train ventilation systems and comprises a negative pressure air tap, a negative pressure ventilation pipe, a vehicle roof device cabin, a positive pressure ventilation pipe, a waterproof cover plate, a waterproof cover plate magnetic clip, a compartment and a vehicle roof skin. The self-adjusting ventilating system is characterized in that the upper part of the negative pressure ventilation pipe is connected with the negative pressure air tap; the top of the negative pressure air tap is provided with a flow line arc-shaped surface outwardly projecting; the top end of the negative pressure air tap is arranged on the vehicle roof; the negative pressure ventilation pipe passes through the lower part of the vehicle roof device cabin and is disposed in the compartment; the top end of the positive pressure ventilation pipe is connected with the vehicle roof; the lower end of the positive pressure ventilation pipe passes through the lower part of the vehicle roof device cabin and is disposed in the compartment; and the top end pipe port of the positive pressure ventilation pipe is aligned to a horizontal plane of the vehicle roof skin. The negative pressure air tap is provided with the flow line arc-shaped surface outwardly projecting, so high-speed air flows generate negative pressure and foul air of the vehicle can be sucked out and fresh air can be supplied via the positive pressure ventilation pipe; air can be exchanged; and the self-adjusting ventilating system is simply structured and requires low cost.
Description
Technical field
Self-regulation ventilation system, relates to train field of ventilation.
Background technology
China railways network spreads all over the country, and railway transport of passengers is still main stream traffic instrument.For a long time, railway transport of passengers passenger flow volume is large, and particularly in the spring transportation summer transportation phase, common attending a banquet is usually full or overcrowding delivery, and crowded passenger is in narrow compartment, and air quality can decline.Regulating for utilizing natural wind makes fresh air enter compartment, the Chinese patent CN202006797U patent of prior art, due to its fresh wind tube 1 and the version of exhaust duct 2, two-way confession 10 place's bending, the pressure reduction between fresh wind tube 1 and exhaust duct 2, by the local resistance loss of 10 bendings, almost approach exhaustion, ventilation effect is very poor, unless fresh wind tube 1 is enough large with the pipe diameter of exhaust duct 2, thus, vehicle operating resistance will increase greatly.By also finding out in its specific embodiment that " be set as by the cross sectional dimensions of exhaust duct (1): 800mm × 300mm, the cross sectional dimensions of fresh wind tube (2) is set as: 500mm × 150mm." will higher than roof 1200 ~ 1400mm, this has highly exceeded the railway clearance standard of China and world's most countries, serious harm traffic safety.According to the regulation of " People's Republic of China's railway technology code " accompanying drawing 2, the height in compartment is less than 4800mm from railroad track end face to vehicle roof equipment vertex.The height of the main flow passenger vehicle 25G type vehicle that China railways is current is 4433mm, if use the height of this equipment vehicle will more than 5633mm, this will overturn the rolling stock clearance standard of China, to cannot implement in China and world's most countries at all, such technical scheme, redesign existing vehicle (if change height of car comprehensively, entire vehicle intensity will be affected, must all redesign), improve the height of railway auxiliary building, as: tunnel, bridge, platform canopy, contact system (electric locomotive high voltage supply line) and garage door etc.
The Chinese patent of prior art: CN2811045Y, is only applicable to automobile, is not suitable for the two-way train started.
Summary of the invention
Present common car is less, is mostly air-conditioned coach, only regulates air by air-conditioning, obviously not enough.Even if passenger train has air-conditioning to exist, it is also very necessary for supplementing as motorless new wind for subsequent use, do not catch fire and really want standing fire distinguisher, but the passenger train of prior art does not but have this backup ventilation system.Namely such as, compartment powers in short supply, once tripping operation of powering, when also electric power system has a fault in car, must ensure in compartment have enough fresh airs.In recent years, air-condition faults happens occasionally, and as 12:27 on May 8th, 2011 divides, to D94 motor train unit train of Hongqiao, stop because a/c system et out of order is forced in station, rivers and mountains in Nanchang; On July 19th, 2009, K226 the train in Lanzhou was left for because of a/c system fault in Guangzhou, can not provide fresh air at about 8 pm, and cause passenger uncomfortable because of unhappy in compartment, what have goes into hospital.This is train fault together, causes visitor to hinder accident owing to not pulling at that time to stop.Such accident is too numerous to enumerate.
Therefore, for overcoming the deficiency that prior art exists
One of object of the application will be invented a kind of motorless energy conversion principle of fluid that utilizes and be supplemented the self-regulation ventilation system of fresh air for compartment;
Two of the object of the application ensures that the rainy day does not leak;
Three of the object of the application ensures train traffic safety;
The application adopts following technical scheme for achieving the above object:
