Fig.

1 to 3, a duct air volume adjusting apparatus 100 according to an embodiment of the present invention includes an insertion rod 10 into which a part is inserted into a duct 11 (see FIG. 5) A plurality of rotating blades 20 radially rotatably installed in the insertion rod 10 and extending in a circular shape in the interior of the duct 11 and a plurality of rotating blades 20 connected to the edges of the rotating blades 20, And a wire member (30) for expanding the wire member (30).

The duct 11 has an air passage 11a (see Fig. 5) through which air is moved. The insertion rod 10 is inserted into the air flow path 11a of the duct 11.

The insertion rod 10 can be fixed in a state where a part of the insertion rod 10 in the length direction is inserted into the inside of the duct 11. For this, an insertion hole into which the insertion rod 10 is inserted may be formed in the side surface of the duct 11. The insertion hole can be formed by a worker setting a predetermined position of a side surface of the duct 11 and performing a drilling operation.

4 is a cross-sectional view taken along the line IV-IV of the insertion rod of FIG.

As shown in FIG. 4, an insertion space 10a into which the wire member 30 is inserted may be formed inside the insertion rod 10. This will be described in more detail below while explaining the wire member 30.

On the other hand, the insertion rod 10 is rotatably installed so that the rotary blade 20 is foldable.

The rotary blade 20 can be positioned inside the duct 11 through the insertion hole of the duct 11 while being installed on the insertion rod 10. [ The insertion of the rotary blade 20 into the duct 11 is for regulating the air volume of the air flowing through the air passage 11a of the duct 11. [ In other words, the rotary blade 20 can be circularly expanded in a state of being inserted into the duct 11 to vary the air flow rate.

More specifically, the rotary blade 20 includes a plurality of first blades 21 rotated in the first direction by the wire member 30 with reference to the rotation center position of the insertion rod 10, And a plurality of second blades 23 rotated in the second direction by the wire member 30 based on the rotational center position of the first blade 10.

The first blades 21 can be rotatably installed on the insertion rod 10 in a state in which a plurality of the blades 21 are foldable. The first blades 21 may be formed in a fan shape so as to be radially spread with respect to the rotational center position of the insertion rod 10. [

In the present embodiment, the first blades 21 can be rotatably installed in the insertion rod 10 in a plurality of directions so as to be spread in the first direction A (see Fig. 3). The insertion bar 10 may be provided with the second blade 23 at an opposed position where the first blade 21 is installed with respect to the rotation center position.

The second blade 23 may be rotatably mounted on the insertion rod 10 so as to be spread in a second direction B (see FIG. 3). The second blades 23 can be rotatably installed on the insertion rod 10 in a plurality of foldable states.

The second blades 23 may be formed in a fan shape so as to be radially spread with respect to the rotational center position of the insertion rod 10. [

Thus, the insertion bar 10 can be provided with the first blade 21 and the second blade 23 so as to be extended along the first direction and the second direction, respectively. This makes it possible to smoothly adjust the amount of air flowing through the internal air flow path 11a of the duct 11. [

On the other hand, the first blade 21 and the second blade 23 can be unfolded by the pulling operation of the wire member 30.

The wire member 30 may include a first wire 31 for rotating a part of the rotating blade 20 and a second wire 33 for rotating the remaining part of the rotating blades 20. [

The first wire 31 may be connected to the first blade 21 among the rotating blades 20 so that the first blade 21 is spread along the first direction. The first wire 31 may be drawn to the outside of the insertion rod 10 through the inside of the insertion rod 10 in a state where one end of the first wire 31 is connected to the first blade 21. Therefore, the operation of deploying the first blade 21 is enabled by the operation of the operator pulling the first wire 31.

The second wire 33 may be connected to the second blade 23 among the rotating blades 20 so that the second blade 23 is spread along the second direction. In the present embodiment, the first direction means counter-clockwise direction and the second direction means clockwise direction.

The second wire 33 may be drawn to the outside of the insertion rod 10 through the inside of the insertion rod 10 while one end of the second wire 23 is connected to the second blade 23. Therefore, the work of pulling the second wire 33 by the worker enables the unfolding operation of the second blade 23. That is, the operator can pull the first wire 31 and the second wire 33 together so that the first blade 21 and the second blade 23 can be deployed in a circular shape inside the duct 11 Do.

Meanwhile, the insertion rod 10 may be provided with a sealing member 40 for sealing between the insertion rod 10 and the duct 11.

The sealing member 40 may include a sealing block 41 provided in the insertion rod 10 and a sealing pad 43 attached to the sealing block 41 to contact the surface of the duct.

The sealing block 41 may be installed at a position close to the rotary blade 20 in a state where the sealing block 41 protrudes outside the insertion rod 10. The sealing block 41 can be fixed to the duct 11 by a fastening member (not shown) such as a bolt in a state where a part of the insertion rod 10 is inserted into the duct 11. A sealing pad 43 may be attached to the sealing block 41.

The sealing pad 43 may be attached to the side surface of the sealing block 41 so as to contact the outer surface of the duct 11. The sealing pad 43 is made of a rubber material and is capable of sealing a portion between the sealing block 41 and the duct 11. Therefore, it is possible to seal the air through the perforated portion of the duct 11 so that the air does not flow out of the duct 11.

On the other hand, the insertion rod 10 may be provided with a fixing member 50 for fixing the wire member 30.

The fixing member 50 can be applied as a bolt member which is installed in the radial direction of the insertion rod 10. [ Hereinafter, the same reference numerals are used for the fixing member and the bolt member.

The bolt member 50 is screwed in the radial direction of the insertion rod 10 so that the wire member 30 can be pressed and fixed in the insertion rod 10. Accordingly, the rotary blade 20 can be stably fixed in a deployed state inside the duct 11 by the stable fixing action of the wire member 30. [

FIG. 5 is a cross-sectional view of the main part schematically showing a state in which the rotating blade portion of the duct air volume adjusting device of FIG. 2 is inserted into the duct, and FIG. 6 is a cross-sectional view of the rotating blade of the duct air volume adjusting device of FIG. And Fig.

Hereinafter, the operation of the duct air volume adjusting device having the above-described configuration will be described in detail with reference to the drawings.

First, as shown in Fig. 5, the operator inserts the rotary blade 20 into the duct 11 through the insertion hole drilled in the duct 11, with the rotary blade 20 folded. That is, the operator can place a portion of the insertion rod 10 into the interior of the duct 11 through the insertion hole while holding the insertion rod 10.

6, the operator pulls the wire member 30 so that the rotary blade 20 is deployed inside the duct 11. Here, the worker can fix the wire member 30 to the insertion rod 10 by using the bolt member 50, thereby stably maintaining the unfolded state of the rotary blade 20.

Next, the operator can selectively adjust the angle at which the rotary blade 20 is installed on the duct 11 by rotating the insertion rod 10 in one direction.

That is, when the size of the air volume to move the duct 11 is increased, the insertion rod 10 can be rotated to rotate the rotary blade 20 in a direction parallel to the air flow path 11a of the duct 11 .

When the size of the air volume to move the duct 11 is reduced, the insertion rod 10 can be rotated to rotate the rotary blade 20 in the direction to close the duct 11.

As described above, the duct air volume adjusting apparatus 100 of the present invention easily adjusts the air volume of the air moving through the duct 11 by inserting the rotating blade 20 into the duct 11 and expanding it It is possible to do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
