Abstract
The utility model relates to an emergency ventilating system of a railway car. Independent emergency ventilators are arranged on the end walls of a car body, and by means of emergency storage batteries, the emergency ventilating system can directionally import the air into the car body and exhaust the air out of the car body, so that the interior of the car body can always be ventilated, which can help improve riding comfort. The emergency ventilating system is mainly provided with the two emergency ventilators which are symmetrically arranged on both longitudinal ends of the car body, and each emergency ventilator comprises a ventilating frame which penetrates the end walls of the car body. An emergency blower is arranged inside each ventilating frame, and an emergency release valve which is used to close or open the emergency ventilator is arranged outside the ventilating frame. An air supply pipeline which can import the compressed air is connected with an air cylinder arranged inside the emergency release valve, the piston rod of the air cylinder is connected with a holddown plate which is closed on the ventilating frame, and a holddown spring is connected with the holddown plate.
Description
Technical field
The utility model relates to a kind of Emergency Venting System that is applied to the high-speed track vehicle, belongs to mechanical manufacturing field.
Background technology
The high-speed track vehicle speed per hour of place in operation has reached more than 300 kilometers at present, and using in every joint compartment has a/c system and fresh air-changing device.When guideway vehicle et out of order and when having a power failure, compound ventilation air-changing device is in outage, readiness for action in the process of moving, thereby cause the inner resh air requirement deficiency of car body, brought certain human discomfort to the passenger.
The Emergency Venting System of existing guideway vehicle adopts the blower fan of air-conditioning unit to carry out induced ventilation and the mechanical type drafting apparatus is not set separately at large.When guideway vehicle broke down or have a power failure, the air-conditioning unit also can correspondingly cut off the power supply and can't carry out induced ventilation, and the emergency ventilation of therefore handling this type of emergency situation becomes the technical barrier of being badly in need of solution.
The utility model content
The utility model provides a kind of guideway vehicle Emergency Venting System, its design goal is to address the above problem and independently emergency ventilation device is set at car body headwall place, emergent electric power storage by configuration is to realize to car body inner orientation importing and air-out, make car body inside be in ventilation state, help improving travelling comfort.
For realizing above-mentioned design goal, described guideway vehicle Emergency Venting System mainly has:
Be arranged on 2 emergency ventilation devices at the vertical two ends of car body symmetrically, each emergency ventilation device includes and runs through the ventilating frame that the car body headwall is installed.
In ventilating frame inside one emergency ventilator is set, is used to seal or open the emergent Dump valve of emergency ventilation device in ventilating frame outer setting one.
As above-mentioned scheme feature, Emergency Venting System can pass through storage battery power supply, and drives 2 emergency ventilation devices simultaneously, makes that maintenance car body in-to-in air is unobstructed under abnormal condition.
2 emergency ventilation devices are arranged on the vertical two ends of car body symmetrically, and to the car body inner blower, the opposite side headwall has formed more favourable air guided flowing to the wind circulation path of the outside air draft of car body from a side wall outside in formation.
Emergent Dump valve is in sealing usually and compresses the state of ventilating frame, drives the logical ventilating frame of opening of emergent Dump valve by standby electricity when guideway vehicle breaks down, and forms air flue.
For further improving the maneuvering performance that emergent Dump valve sealed or opened the emergency ventilation device, can take following improvement project:
Import compressed-air actuated supply air line, be connected in emergent Dump valve in-to-in cylinder, the piston rod of cylinder is connected in the pressing plate that is enclosed on the ventilating frame, is socketed with holddown spring on the pressing plate.
For improving the fresh-air ventilation performance of guideway vehicle, ventilating frame is arranged in the air interchanger of car body end, and the emergent air channel in the air interchanger is connected in emergency ventilator.
For improving the air-tightness between emergency ventilation device and the car body headwall, described ventilating frame is installed in the car body headwall by airtight welding.
For further guaranteeing the normal operation and maintenance of emergency ventilation device, one inspection door and air grid are set at emergency ventilation device sidepiece.
As mentioned above, the advantage that the utility model guideway vehicle Emergency Venting System has is, break-through car body headwall and the independent emergency ventilation device that is provided with, can break down or during the outage of other fresh air-changing devices at guideway vehicle, rely on back-up source to open air flue, realization is to car body inner orientation importing and air-out, and emergency ventilation mode dependable performance, effective helps improving travelling comfort.
Description of drawings
Now in conjunction with the following drawings the utility model is described further;
Fig. 1 is the generalized section of car body part;
Fig. 2 is that A among Fig. 1 is to structural representation;
Fig. 3 is that B-B among Fig. 2 is to cut-away view;
Have car body 1, headwall 11, emergency ventilation device 2, ventilating frame 3, emergent Dump valve 4, cylinder 41, pressing plate 42, holddown spring 43, emergency ventilator 5, supply air line 6, emergent air channel 7, inspection door 8, air grid 9 as shown in Figure 1 to Figure 3.
The specific embodiment
In each emergency ventilation device 2, ventilating frame 3 is installed in the car body headwall 11 by airtight welding.
In ventilating frame 3 inside one emergency ventilator 5 is set, is used to seal or open the emergent Dump valve 4 of ventilating frame 3 in ventilating frame 3 outer setting one.
Import compressed-air actuated supply air line 6 from the outside, be connected in emergent Dump valve 4 in-to-in cylinders 41, the piston rod of cylinder 41 is connected in the pressing plate 42 that is enclosed on the ventilating frame 3, is socketed with holddown spring 43 on the pressing plate 42.
Ventilating frame 3 is arranged in the air interchanger of car body 1 end, and the emergent air channel 7 in the air interchanger is connected in emergency ventilator 5.
At emergency ventilation device 2 sidepieces one inspection door 8 and air grid 9 are set.
Above-mentioned Emergency Venting System passes through storage battery power supply, and drives 2 emergency ventilation devices simultaneously, makes that maintenance car body in-to-in air is unobstructed under abnormal condition.
Under normal conditions, emergent Dump valve 4 is in off-position, and supply air line 6 does not import pressurized air to cylinder 41, by holddown spring 43 pressing plate 42 is pressed on the ventilating frame 3, and emergency ventilation device 2 is in air-tight state.
When guideway vehicle breaks down or during the outage of air-conditioning, fresh air-changing device, storage battery is to 2 power supplies of emergency ventilation device, emergent Dump valve 4 powers on and conducting supply air line 6, the cylinder rod that pressurized air promotes cylinder 41 overcomes the pressure of holddown spring 43 and pressing plate 42 is broken away from ventilating frame 3, emergency ventilation device 2 is opened, and forms the air flue between car body 1 vertical two ends.
