Abstract
The utility model relates to an end fresh air intake device. The air inlet of an air interchanger is moved to the outside of the end of a carriage body, and the imported fresh air is led to the underside of a carriage through an in-floor air duct and directly connected with the fresh air inlet of the air interchanger, so that the fresh air inlet of the air interchanger can be positioned at a far end far from the accumulated dust, so the maintenance period of a fresh air filter net can be effectively prolonged. An end fresh air duct is arranged on the outside of an end wall of the carriage body. The upper end of the end fresh air duct is provided with a rainproof air inlet; the lower end of the end fresh air duct is connected with the in-floor air duct positioned on the bottom of the carriage body; and the in-floor air duct is connected with the fresh air inlet of the air interchanger through a bottom connecting air duct. The end fresh air duct is directly fixed on the outside of the end wall by bolts. The in-floor air duct, which is connected with the outer end of the end fresh air duct, is connected with the end wall by airtight spot welding. The lower end of the end fresh air duct is provided with a plug-in filter net. An end fresh air duct inspection door is arranged on the side of the middle section of the end fresh air duct. The rainproof air inlet has a bilateral maze type air inlet structure.
Description
Technical field
The utility model relates to a kind of end that is applied to the high-speed track vehicle and advances aeration device, belongs to mechanical manufacturing field.
Background technology
The speed per hour of place in operation reaches the motor train unit more than 200 kilometers at present, and using in every joint compartment has a/c system.For preventing that the guest room outside pressure variation from having influence on the guest room internal environment, the guest room is installed in existing motor train unit car body bottom ventilates with for, exhaust integrated continuous air interchanger.
Above-mentioned existing continuous air interchanger adopts electronic bellows to carry out continuously after a period of time, all occurring stained, the phenomenon of blocking in paper filter air port at on-line running to, exhaust.Increasing the weight of gradually of, latch up phenomenon stained along with paper filter air port, the resh air requirement that air interchanger is supplied with to inside, guest room also reduces gradually, and then causes inside, guest room to produce bigger negative pressure gradually.
When the motor train unit high-speed cruising enters the tunnel, high slow down or cross phase-splitting and stop when opening car door, directly cause the acute variation of guest room air pressure inside and easily make the passenger produce the sensation of tinnitus, be unfavorable for improving travelling comfort.
If cleaning or replacing paper filter air port had both increased the maintenance workload that equipment uses on schedule, also correspondingly increased operation cost.
The utility model content
The utility model provides a kind of end to advance aeration device, its design goal is to address the above problem and the ventilation inlet of air interchanger is moved to the outside, end of car body, the fresh air that is imported into cause under the car by air channel in the floor and with the fresh wind port direct connection of air interchanger, make the fresh wind port of air interchanger be positioned at the far-end that gathers away from dust, thereby can prolong the maintenance intervals of new wind filter screen effectively.
For realizing above-mentioned design goal, described end is advanced aeration device and is mainly had:
The headwall outside at car body is provided with fresh flue, an end.
Upper end, fresh flue, end is provided with the rain proof type air port, and its lower end connects the air channel, floor that is arranged in the car body bottom, and the air channel is connected with the air interchanger fresh wind port in the connection air channel down by car in the floor.
As above-mentioned scheme feature, the fresh air that is imported into enters into pipeline from the fresh flue, end, and the wind passage mouth that the fresh wind port of air interchanger enters away from new wind, so the air port of air interchanger is difficult for by stained and obstruction.
Further refinement scheme is, fresh flue, described end directly is fastened on the headwall outside by bolt.
For improving the air-tightness that new wind enters pipeline, the fresh flue connects the outer end of fresh flue, end in the described floor, is connected by airtight spot welding with headwall.
For improving to entering the strainability of fresh air, reduce the quantity that dust enters the car body pipeline, be provided with the plug-in type filter screen in the bottom of fresh flue, end.
For improving cleaning and maintenance, be provided with fresh flue, end inspection door at the stage casing of fresh flue, end sidepiece to the fresh flue, end.
For preventing that rainwater and dust storm from entering in the aeration device of end, described rain proof type air port has the labyrinth type tuyere structure of both sides.
As mentioned above, the utility model end is advanced the advantage that aeration device has and is, the ventilation inlet of air interchanger is moved to the outside, end of car body, and the fresh wind port of air interchanger is positioned at the far-end that gathers away from dust, can prolong the maintenance intervals of new wind filter screen effectively.Neither can have influence on air interchanger to the resh air requirement of guest room internal feed, help improving travelling comfort, also help control convenience maintenance workload and operation cost.
Description of drawings
Now in conjunction with the following drawings the utility model is described further;
Fig. 1 is the structural representation of car body bottom;
Fig. 2 is the sectional structure chart of fresh flue, end;
Fig. 3 is the side cut-away view of Fig. 2;
As shown in Figure 1 to Figure 3, be air interchanger fresh wind port 1, car connects air channel 2 down, and the air channel 3 in the floor, fresh flue, end 4, rain proof type air port 5, plug-in type filter screen 6, fresh flue, end inspection door 7, car body 10, headwall 11.
The specific embodiment
4 upper ends, fresh flue, end are provided with rain proof type air port 5, and rain proof type air port 5 has the labyrinth type tuyere structure of both sides, has functions such as dustproof, rainproof, and near the fluctuation of pressure the ventilation inlet is less.
The lower end of fresh flue, end 4 connects the air channel, floor 3 that is arranged in car body 10 bottoms.The new wind that enters from the end enters air interchanger through the fresh flue, end, and the bonded assembly air channel is to be connected air channel 2 under the car between the fresh flue 3 in air interchanger fresh wind port 1 and floor.
In the floor in the interlayer on floor, 3 position, air channel, air channel 3 need the airtight welding of the property advanced in a joint air channel of stretching out headwall 11 in the floor, guarantees the air-tightness of car body.Just, the outer end that fresh flue 3 connects fresh flue, end 4 in the floor is connected by airtight spot welding with headwall 11.
Be provided with plug-in type filter screen 6 in the bottom of fresh flue, end 4, thereby have convenient disassembly, be convenient to advantages such as cleaning.
Be provided with fresh flue, end inspection door 7 at the stage casing of fresh flue, end 4 sidepiece, both can overhaul emergent Dump valve, also play cleaning air channel in-to-in effect.
Fresh flue, end 4 is fixed on headwall 11 outsides by bolted connection, its outside between windscreen and the interior windscreen.When crossing small curve radius, the position of 4 both sides, fresh flue, end and inside and outside windscreen can guarantee the maximum secting area in air channel in fresh flue, end 4, and then guarantees the resh air requirement requirement of air interchanger.
