By moving the exhaust hood 5, the damper blades 31 are sequentially opened and closed, and the hood blowing port provided in the ceiling panel 51 communicates with the damper blade opening portion of the duct, so that the exhaust hood 5 is connected to the duct 1
It can be exhausted inward at any position. 3 is an enlarged side view showing a portion A of FIG. 2, FIG. 4 is a sectional view taken along line XX of FIG. 2, and 1 is a duct, and a rail mounting plate 11 fixed to the duct 1 is used. The rail 12 is attached to the duct, and the hood ceiling panel 51 is attached to the rail 12 via the roller 54.
The ceiling panel 51 can be moved along the duct 1 by pressing the handle 55 fixed to the unit 1. Damper blade 31
A cam plate 33 is attached to one end of the rotating shaft 32 of the seat plate 22 at a position corresponding to the cam plate 33 of the hood ceiling panel 51.
The cam drive plate 21 is attached via. In the illustrated example, the roller 23 provided on the peripheral edge of the cam drive plate 21 and the cam plate are engaged with each other. The cam drive plate 21 is a seat plate 22.
Since the bolt 25 is attached to the cam drive plate 21 through the long hole 24, the position of the cam drive plate 21 can be adjusted slightly in the vertical direction. Reference numeral 52 denotes a hood blowing port that extends from the hood ceiling panel 51 to the lower end of the duct 1 and exhausts air from the hood 5 into the duct 1, and moves along the lower end of the duct 1 as the hood 5 moves. As shown in FIG. 3, the upper end of the front part of the hood blow-in port 52 (the same applies to the rear part) is a tip elastic part 53 such as a vinyl chloride plate for sealing. Furthermore, damper blade 3
1 has a tip sealing plate 34 at its tip, and when the damper blade 31 is closed, the lower end of the tip sealing plate 34 engages with the silicon packing 35 as shown by the chain double-dashed line 31 ′ to ensure airtightness. To keep.

ことができる。As an example, when cleaning an air conditioner installed on the roof of a train, a duct 1 having damper blades continuously arranged in parallel is provided on the lower surface, and one end of the duct communicates with a dust collector.
A vehicle is placed below the duct 1, and an exhaust hood 5 covering the roof of the vehicle is moved between the vehicle and the duct 1.
Then, the cam plate is flipped up at a position where the roller 23 of the cam drive plate 21 and the cam plate 33 are engaged with each other, and the damper blade 31 is also opened by the rotation thereof. (Solid line in FIG. 3) Thereby, the damper blade above the hood blow-in port 52 is opened, and when the cam drive plate 21 passes, it is closed again. (Two-dot chain line in FIG. 3) In cleaning, if the pressure air pipe is pushed from between the hood 5 and the pressure air is blown to the cleaning location, the damper blades above the hood are opened, so dust and air are removed. It is sucked into the duct 1 and sent to the dust collector connected to the duct. In the present invention, since the duct in which the damper blades are continuously provided is used, it is possible to communicate with the duct by moving the exhaust hood 5 even if the position of the cleaning portion such as the air conditioner is different each time. Can be exhausted at the position. Further, by appropriately setting the shape of the cam plate and the inclination of the cam drive plate, it is possible to rotate the cam plate even if the intake / exhaust means such as the exhaust hood is moved in either direction. .
