Description
Technical field
The utility model relates to locomotive equipment and makes the field, is specially a kind of sidepiece static pressure air delivery duct.
Background technology
The mode of bottom or sidepiece static pressure is generally adopted in static pressure air delivery duct on the existing urban rail transit vehicles, from the static pressure principle, removes the gravity of air own; The former is as broad as long with the latter's static pressure effect; But,, adopt the mode of sidepiece static pressure can more make full use of the space because vertically limited space is many for rail traffic vehicles; Bigger plenum chamber can be set, obtain better static pressure effect.
On urban rail transit vehicles; Because the restriction of top ceiling superjacent air space, if in general plenum chamber is less in the air delivery duct of employing bottom static pressure, the effect of static pressure air-supply is insufficient; In addition; The layout of beam can interrupt the bottom plenum chamber of part air delivery duct owing to adorn in length and breadth in the vehicle again, thereby causes the air-supply zone of part the air-supply dead angle to occur, and these have all influenced the air-supply homogeneity of air delivery duct.
Summary of the invention
For the air-supply zone that overcomes existing static pressure air delivery duct is prone to the air-supply dead angle, or the bad deficiency of air-supply homogeneity, the utility model aims to provide a kind of sidepiece static pressure air delivery duct; The mode of perforation in the middle of adopt this static pressure air delivery duct; Can crossbeam be arranged in the top, air delivery duct, middle perforate is in order to pass through beam Connection Block in length and breadth, and so the plenum chamber of the sidepiece of air delivery duct is just bigger; Static pressure air-supply better effects if more is prone to evenly and not blow the dead angle.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of sidepiece static pressure air delivery duct; Comprise the wind pushing cavity of forming by air channel top board and air channel base plate, the vertical air channel framed side wallboard of arranging and the air channel end plate of lateral arrangement; Its constructional feature is, in wind pushing cavity, is provided with two vertical stationary. platen of arranging, this stationary. platen is separated into main air-supply passage and the plenum chamber that is positioned at main air-supply passage both sides with wind pushing cavity; Have a plurality of static apertures on the said stationary. platen, have exhaust vent on the base plate of said air channel, and this exhaust vent be positioned at plenum chamber under; Said air channel top board is provided with the transition air channel that is used for air intake, and this transition air channel be positioned at main air-supply passage directly over.
Thus, air-supply is blown into from position, transition air channel, and ahead running in main air-supply passage under hydrostatic pressure, through the static aperture entering sidepiece plenum chamber of side plate stationary. platen, is seen off then.
Have the longeron hole on said air channel top board and the air channel base plate; Be provided with intermediate hsg and internal partition around the said longeron hole; The two ends up and down of this intermediate hsg and internal partition are connected to air channel top board and air channel base plate, and longeron hole and wind pushing cavity are isolated, and seal between wind pushing cavity and the longeron hole; Thereby the main air-supply passage that makes wind pass through wind pushing cavity gets into plenum chamber through static aperture, is seen off by exhaust vent then.
Static aperture on the said stationary. platen is more than the quantity near the position of air outlet near the quantity of the position of ventilation inlet, can be so that the wind speed that gets in the plenum chamber is more even.
For the ease of installing, on the framed side wallboard of said air channel protruding bracket is housed.Further, between said air channel framed side wallboard and protruding bracket, be provided with heat insulation foam.
In order to guarantee to connect firmly, said intermediate hsg links to each other through connecting panel with internal partition.
By said structure; The utility model air delivery duct mainly contains air channel top board, connecting panel, air channel base plate, air channel framed side wallboard, air channel end plate, end flange and protruding bracket and forms; Be provided with intermediate hsg and internal partition in the centre; With the sealing of perforate part in the middle of guaranteeing, isolate the sidepiece plenum chamber through stationary. platen at main air-supply passage side.Through choosing suitable air delivery duct sectional dimension, enter the mouth out wind speed in the reasonable scope to guarantee the air delivery duct; The homogeneity of sending before and after the mode that static aperture on the inside static pressure plate of air channel is dredged through preceding close back guarantees; Through the air channel test, front portion, air delivery duct still wind speed is less, and a small amount of deflecting plate of anterior layout can transfer to wind speed evenly in the air delivery duct.
Compared with prior art, the beneficial effect of the utility model is:
1, the utility model is suitable for the railcar installation of beam in length and breadth; Still have air-supply in beam mounting portion in length and breadth, the air-supply dead angle still less;
2, the sidepiece plenum chamber size of the utility model is bigger, the static pressure better effects if;
3, the utility model adopts independently air delivery duct design, has cancelled distribution box and flat air delivery duct, has reduced the air delivery duct resistance, and air channel design and adjustment are simpler, and cost is lower.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.
