The present invention relates to a damper device installed in the ventilation chamber ratio of a building,

In particular, it is installed in the right place of the duct to control the air flow and block the air flow to maintain a completely closed state, but the structure is not complicated structure.

In more detail,

Wings that control the flow of air are operated in the concave indents on the sides of the devices, and the mutually adjacent wings allow the two ends to overlap each other to improve the sealing effect. It is an object of the present invention to provide such a damper device that can be operated more smoothly by bearing through a bearing.

As is well known, dampers are generally used to supply fresh air into a building's interiors in normal times, and in the event of a building's fire, it is possible to discharge smoke such as fumes and toxic gases to the outside, and flames spread along the duct. It is used to prevent it.

1 is an exemplary view showing a conventional damper apparatus 1.

The wing 2 for opening and closing the duct 6 is operated by the motor 4 and on the outside side the auxiliary wing 3 is separately provided so that the wing 2 does not leak out of the building wall 8. It is installed.

In such a state, when the air in the room, for example, smoke or toxic gas from the fire is to be discharged, the blades 2 are operated by the motor 4 to open the passage of the duct 6. Although not shown as is to suck the smoke by the blowing fan to be discharged.

However, the damper device 1 is pointed out as the following problems.

In the state in which the wings 2 are normally closed, outside air (outside air) flows in through the auxiliary blades 3, so that the upper and lower sides of the wings 2 and the device of the damper device 1 pass through the gap between the devices. There is a problem that a phenomenon that the flow back into the room (7) flows into the room occurs,

Dust or foreign matter is introduced from the outside between the wing 2 and the device, and the dust and foreign matters are accumulated and solidified due to prolonged inactivity. There was also a problem that occurred until the phenomenon that the wing (2) detained by the laminated dust is not operated smoothly,

In particular, since touching the blade (2) actuated by the motor (4) is a burden on the motor (5) separate auxiliary wings (to prevent the touch of the blade (2) from the outside of the building wall (5) 3) there is a problem of having to install and thus the production cost increases.

In addition, the damper device, which is not specifically shown to be developed by the wind power, there was a problem that the wing is unreasonably open when the wind power of the blowing fan is too strong, the wing is not open.

The damper device 10 is known as shown in FIG. 2 to solve these problems.

In the center of the support frame 11, the shaft rod 13 in which the blade 14 is integrated is compressed, and flanges 15-1, 16-1, 17-1 ( Curved sealed portions 15, 16, 17 and 18 having 18-1 are provided, but curved sealed portions 15, 17 and 16 are formed on both ends of the same wing 14, respectively. ) Is formed in the opposite direction, and the sealing packing shaft rod 19 is condensed between the curved sealing portions 16 and 17 overlapping when the wings 14 adjacent to each other are folded, and the upper surface 11-1 and the bottom are condensed. On the surface 11-2, stoppers 12 and 12-1 are provided so that the flange portions 15-1 and l8-1 of the wings 14 positioned on the upper and lower sides are brought into contact with each other. The wing 14 is connected to the connecting rod 22 through the connecting member 21.

In the conventional damper device 10 as described above, when the connecting rod 22 is operated up and down by any means, the blade 14 is opened and closed while being rotated forward and backward by 90 ° with respect to the shaft 13. Each wing 14 is in a horizontal state (shown in solid line) and when closed, each wing 14 is in a vertical state (shown in phantom line).

Particularly, in the closing, the wing 14 positioned on the upper side is the wing 15 positioned on the lower side after the flange portion 15-1 of the curved airtight portion 15 is connected to the stopper 12 on the upper surface 11-1. 14, the flange portion 18-1 of the curved sealing portion 18 is connected to the stopper 12-1 of the bottom surface 11-2 and stopped, and the curved sealing portion of the adjacent blade 14 ( 16) and (17) are softened as if enveloping the sealed packing shaft bar (19) and overlap each other facing each other.

The conventional damper device 100 operated in this way is pointed out as a disadvantage as follows.

When the damper device 10 is in a closed state, the curved sealing portions 16 and 17 of the wings 14 are abutted as overlapping the sealed packing shaft rod 19, so that air flow is somewhat blocked, but the wings ( 14) because both sides of the support frame 11 and the side is spaced apart from the outside air (outdraft) is introduced between these gaps there was a problem that backflow into the room,

Since the overlapping curved sealing portions 16 and 17 of the wings 14 are curved outwardly as opposed to the tongue, the overlapping curved sealing portions 16 and 17 are connected to the sealed packing shaft rod 19. There was also a problem that the production time and costs are high due to the manufacturing hassle to transverse the sealed packing shaft rod 19 in order to lose,

Since the shaft bar 13 of the wing 14 is simply installed in the side of the support frame 11 is simply inserted, there is a problem that the left and right fluctuations occur between the shaft bar 13 and thus cannot operate smoothly.

In addition, since the curved sealing portions 15, 17 and 16, 18 formed at both ends of the wing 14 are curved in opposite directions, it is easy to form a press mold for forming the wing 14. That's not good.

The present invention is to provide a damper device that can solve the above problems.

The object of the present invention is to provide a damper device to further improve the sealing effect to prevent the inflow of outside air backflow.

Another object of the present invention is to provide a damper device for forming a frame to form a concave portion for guiding and supporting the wing on the inner side of the side plate so that the wing can operate smoothly without fluctuation, and thus can be operated smoothly even in a closed state. To provide.

Another object of the present invention is to provide a damper device that enables to achieve a sealing effect without easily laying a separate packing shaft rod, and to be easily manufactured.

Still another object of the present invention is to provide a damper device that is maintained in a closed state (closed) by the self-weight of the long side wings by biasing the shaft rod 42 fixed to the wing 41, the present invention Still another object is to provide a damper device that can be operated more smoothly by placing the shaft of the wing on the side plate through the bearing through the bearing.

The above and other objects of the present invention,

The stoppers 33 and 34 are fixed to the inner side surfaces of the upper plate 31 and the lower plate 32 of the apparatus frame 30-1 so that the wings 41 are fixed to the opposite side plates 36. In the shaft bar 42 is laid in multiple stages, but adjacent wings 41 are arranged so that the curved airtight portions formed in opposite directions on both ends thereof overlap each other,

The wing plate 37 and 36 are repeatedly connected to the side plate 36 in the up and down direction of the shaft bearing hole groove 39, and the wing blades 37 and 36 are adjacent to each other. The vertical contact surfaces 37-2 and 36-2 overlap and communicate with each other in the communication section 38,

It is achieved by the adapter 30, which is formed by forming the connecting portions 43 and 44 formed at both ends of the blade 41 in the same direction.

Since the present invention is constructed as described above, the wings 41 which are constructed by interposing the shaft bearings 40 in the shaft bearing insertion grooves 39 are limited to be opened only in the blade insertion portions 36 and 37, When the bearing force is removed in the horizontally rotated open state, the deflection is deflected, and when the bearing force is removed in the horizontally rotated open state, the long side wing part 41 is formed in the blade 41 by the shaft rod 42 fixedly deflected. -1) while being rotated in an upright state by the weight of self, the connecting portions 43 and 44 of the adjacent blades 41 are connected to each other on the line of the communicating portion 38 and overlapped, and are sealed. The front and rear surfaces of both side ends are in close contact with the vertical contact surfaces 36-2 and 37-2 to block the outside air introduced to the outside.

Hereinafter, the above and other objects, features, and effects of the present invention will be more clearly understood by the following detailed description based on the accompanying drawings.

3 to 5 are exemplary views of the damper device 30 in a specific embodiment according to the present invention.

The inside was made into the space part 30-2 and the open rectangular parallelepiped apparatus frame 30-1 was formed. The apparatus frame 30-1 is made of the upper plate 31, the lower plate 32 and the side plate 35 as an integral type, and can be separately manufactured to be integrated by a method such as welding. The recessed portion formed on the inner side of 35 may press the steel sheet or mold the mold.

In the frame 30-1, the stoppers 33 and 34 are fixed to the inner surfaces of the upper plate 31 and the lower plate 32 in the longitudinal direction, but the side plate 36, which will be described in detail later, has a shaft bearing recess groove. As fixed to maintain a slight deviation back and forth on the same line as (39), as shown in Fig. 5 specifically, the fixed stopper 33 of the upper plate 31 is fixed slightly to the left side and the lower plate ( The stopper 33 fixed to 32 is fixed slightly to the right side.

In particular, the stopper 33 on the top plate 31 is formed in the same shape as the connection portion 43 in consideration of the connection portion 43 formed on both ends of the wing 41 which will be described later in detail, but the stopper 33 Concave-convex portions formed in the connecting portion 43 of the wing 41 is to be connected to each other while wrapped outside.

The stoppers 33 and 34 of the upper and lower plates 31 and 32 are in an upright state so as to close the space part 30-2, that is, the wing 41 which is fixed to the side plate 35 is closed. When the connection part 43 of the blade 41 which is affixed to the uppermost side and the connection part 44 of the blade 41 which is affixed to the lowermost side are respectively connected, the space part 30-2 is reversed up and down. It blocks the outside air to be introduced.

As shown in FIGS. 3 and 5, the side plate 35 is provided with a shaft bearing indentation groove 39 at equal intervals so that the shaft rod 42 of the wing 41 can be easily compressed. The shaft bearing indentation part 39 is formed in the main body so as to be in communication with the shaft bearing inlet groove 39, but the wing indentation part 37 is formed on the upper right side, and the wing indentation part 36 is formed on the lower left side. Considering the rotation of 41), it was formed into quadrant circles.

In particular, adjacent wing recesses 36 and 37 are formed so as to overlap each other, except for the wing recess 37 at the uppermost stage and the wing recess 16 at the lowermost stage, and the overlapping portion communicates with the communication section 38. When the wing 41 is in a closed upright state, the connecting portion 44 and the connecting portion 43 of the upper and lower sides of the wing 41 can be easily connected to each other, and each wing recess 37 Settle groove 37-3 on the outer side of the horizontal contact surface (37-1) in the) to accommodate the protruding connecting portion 43 when the wing 41 is in a horizontal state,

In the lower wing indentation portion 36, a lower recess 36-3 is formed at the lower side of the vertical contact surface 36-2 to accommodate the connecting portion 44 protruding when the wing 41 is in a vertical state. I could do it.

The shaft bearing insertion groove 39 of the side plate 35 formed as described above is inserted into the shaft bearing 40 so as to lose the shaft 42 of the wing 41, and the shaft 42 is in the shaft bearing 40. In order to be rotated in a smooth operation (rotation) and to minimize the left and right fluctuations, in particular, both ends of the wing 41 is built in the state accommodated in the wing indentation (36, 37).

The wing 41 is formed in the same direction in consideration of being connected to each other in the wings recessed portion 36, 37 formed in the concave-convex portion 43, 44 at the front and rear side ends, shaft rod 42 ) To be deflected to one side to coincide with the wing indenters 36 and 37 so that when the force is removed in the horizontal state, the frame itself is rotated downward by the weight of the long wing 41-1. The space part 30-2 of) was made to be closed.

The effect will be described below.

The damper device 30 according to the present invention is opened and closed as shown in (a) and (b) of FIG. 4.

The state shown in (a) is an exemplary view showing a state in which the space part 30-2 of the apparatus frame 30-1 is closed, and shows a normal state.

The wing 41 which has been built up is kept in an upright state by its own weight of the long side wing portion 4l-1 with the long side wing portion 41-1 downward and the short side wing portion 41-2 upward. will be.

When the wing 41 maintains the upright state, the connecting portion 43 of the wing 41 which is arranged at the top end is connected to the stopper 33 of the upper surface plate 31 to block external air from entering the upper end, Since the connecting portion 44 of the blade 41 arranged at the lower end is connected to the stopper 34 of the lower plate 32 in a state where it is placed in the settling groove 36-3 of the vertical contact surface 36-2. It will block the outside air that wants to flow to the bottom.

In particular, when the blade 41 is in an upright position, the short-wing blade portion 4l-2 is in a state where the left and right sides thereof are connected to the vertical contact surface 37-2 of the blade recess portion 37, and the long-axis blade portion 41-1 is provided. The left and right sides are kept in contact with the vertical contact surface 36-2 of the wing indentation 36, so that the outside air to be introduced to both sides of the space portion 30-2 is blocked.

In addition, when the wing 41 is in an upright state, the wing 41 adjacent to the upper and lower sides is maintained in the state in which the connecting part 44 and 43 are connected by repositioning on the line of the communicating part 38, The outside air to be introduced is blocked.

(B) of FIG. 4 is an exemplary view showing a state in which the damper device 30 is operated.

Each wing 41 is not shown in detail but is opened by the pressure of the strong wind of the fan, which is not shown or operated by a power connection such as a motor and a conventional connecting member.

When the blade 41 is rotated by the power means or power, the shaft 42 is rotated in the shaft bearing 40 so that it is rotated very smoothly, the shaft bearing 40 is operated in a state in which the left and right swing is extremely limited ( Rotation).

As shown in (b), the long side blade portion 41-1 of each blade 41 when rotated in a horizontal state and The side wing portions 41-2 are respectively connected to the horizontal tight surfaces 36-1 and 37-1 of the wing recesses 36 and 37, and the joint 43 is a horizontal tight surface 37-. Since the wing 41 is placed in the car recess 37-3 of 1), the blade 41 is too rotated to be opened and thus is easily rotated when the power of the power means is removed.

Particularly, when the blade 41 is rotated between the side plates 35, both ends thereof are accommodated in the blade recesses 36 and 37 and the shaft 42 is built up in the shaft bearing 40. Left and right fluctuations are suppressed as much as possible, and when the power or wind power is removed, each wing 41 is rotated downward by the weight of the long side wing portion 41-1, as shown in (a) of FIG. 30-2) will be closed.

As described above, according to the present invention, when the wings 41 are in a vertical state, each of the wings 41 is connected to each other by connecting the joints 43 and 44 with each other, and both sides are vertically contact surfaces 36-2 and 37-. 2), the upper and lower ends of the stopper 33, 34 and the connecting portion 43, 44 is in close contact with the sealing force is greatly improved, the shaft 42 is built in the shaft bearing (40) Since both ends of the wing 41 are operated in the state of being accommodated in the wing indents 36 and 37, the fluctuation of the wing 41 is suppressed and is operated very smoothly. When the wing 41 is in a horizontal state, the horizontal contact Since the angle rotated by the planes 36-1 and 37-1 is suppressed, when the pressure is removed, the space 30-2 is closed by being directly rotated by its own weight. They are completely shut off and open immediately in an emergency to maximize the efficiency of the actual cost as well as overlapping blades. Since it is cut off from the outside by a dog, it is possible to reduce the manufacturing cost because it does not have to have a separate auxiliary wing for protection.
