Description

Supply damper automatic switch {Automatic damper modulator}

The present invention protects human life by preventing the suffocation by smoke in case of fire by opening the DAMPER installed in the duct of the building in case of fire and introducing fresh air into the evacuation stairs to prepare for evacuation passage. The present invention relates to an automatic switch of an air supply damp wave to provide an evacuation time and an evacuation space.

In case of fire in high-rise buildings, it is common to suffocate first by the smoke and toxic gas generated along with the flame before the direct damage by the flame.

Therefore, the building law stipulates that buildings with more than six floors should be provided with air supply facilities. The air supply should have a structure that can be opened automatically by smoke detectors or heat detectors. The law stipulates that opening must have a structure that cannot be closed by airflow generated by air supply.

The present invention relates to an air supply dam breaker for automatically opening and closing the air supply dam installed in the duct of the building, and in particular, to set the opening angle of the air supply dam wave arbitrarily.

That is, a blower for supplying air to the duct is installed on the roof of the building, and fresh air is introduced in the event of a fire through a supply air inlet, that is, an air supply dam, installed on each floor of the building through the duct, but a blower installed on the roof In the high floor near to the high pressure, a large amount of air flows in, but in the lower floor far from the blower, the air flowed into the duct from the blower causes a loss of air pressure in the middle, resulting in a high air pressure as in the high floor. Will not be.

Therefore, when supplying fresh air to the evacuation stairs in the building through the air duct from the blower installed on the roof through the duct in case of fire, the opening angle of the air supply dam is reduced on the high floor to reduce the amount of high-pressure inlet air. In the lower floors, the opening angle of the supply dam should be increased to increase the amount of inlet air.

The present invention is inserted into the drive shaft for driving the air supply dam wave, so that the opening angle of the air supply dam wave can be arbitrarily adjusted so that when the air pressure flowing in the high floor is high, the opening angle is adjusted small. If the air pressure is weak, the air supply damper automatic switchgear can be arbitrarily adjusted so that the opening angle of the air supply dam is maintained to keep the amount of air flowing into the evacuation step of each floor constant by increasing the opening angle. It is about.

In the damper opening and closing device is fixed to the drive plate 21 is connected to the reduction gear 32 and the motor 33 by the power output shaft gear 31,

The drive plate 21 inserted and fixed to the pivoting hole 12 is formed in a circular shape, and partially forms the drive gear 22 on the circular edge thereof, and the edge of the drive plate 21 on which the drive gear 22 is not formed. The first and second grooves 23 and 24 for activating the first limit switch 18 attached to the lower bay 16 are formed therein,

A plurality of angle setting holes H1 to H17 and a plurality of small topper pin holes S1 and S2 are formed on the surface of the driving plate 21, and a stopper 28 is inserted into one of them.

Insert the angle adjusting shaft 41 to the outside of the rotation hole 12, the lower end of the angle adjusting shaft 41 is engaged with one of the angle setting holes (H1) ~ (H17) of the drive plate 21 (45) ) To fix the angle adjustment plate 42 inserted into the bottom to protrude,

The angle adjusting plate 42 forms a second limit switch 19 operating groove 43 and a stopper guide groove 44 attached to the lower plate 16,

A spring 51 is inserted into the angle adjusting shaft 41 and an angle adjusting groove 46 and an angle display guide 47 are formed at the end to adjust the angle by rotating the angle adjusting shaft 41. The opening and closing angle scale 75 to display the opening and closing angle is formed on the surface.

In the drawings, reference numeral 72 designates an input terminal, 73 a manual connection connector, and 74 a dip switch.

The present invention having such a configuration will be described in more detail and at the same time as follows.

The air supply damping wave drive shaft 71 inserted into the rotating hole 12 is fixed by the fixing bolt 12-1 of the rotating hole 12,

The supply air damping drive shaft is rotated by the rotation of the rotation hole 12 to open the supply air damping wave.

That is, the gear 22 partially formed on the edge of the drive plate 21 inserted into the pivoting hole 12 meshes with the output shaft gear 31 of the reducer 32 and is formed on the drive plate 21. The second grooves 22 and 23 operate the first limit switch 18 fixed to the lower plate 18.

The position of the driving plate 21 at the position where the first limit switch 18 is inserted into the first recess 23 of the driving plate 21 corresponds to the initial state in which the driving plate 21 is not rotated. When the driving plate 21 is rotated in the counterclockwise direction to rotate the pivoting hole 12) This corresponds to the state of the normal dam wave in which no fire has occurred.

However, when a fire occurs, when the fire occurrence signal is applied to the main body through the input terminal 72 by the fire detector or the smoke detector, the motor 33 is driven to operate and rotate the reducer 32, The output shaft gear 31 rotates the drive gear 22 of the drive plate 21 meshed with the output shaft gear 31 to rotate the drive plate 21 and the rotational hole 12 fixed thereto. The air supply dam wave driving shaft 71 is rotated to open the dam wave to supply fresh air to the emergency exit provided with the evacuation step in case of fire.

As described above, the rotation angle of the driving plate 21 rotated by the rotation of the speed reducer output shaft gear 31 includes a plurality of angles formed on the driving plate 21 into which the ball 45 protruding from the bottom of the angle adjusting plate 42 is inserted. The driving plate 21 is rotated by an angle corresponding to the setting holes H1 to H17.

When the bottom surface of the angle adjusting plate 42 is inserted into the holes H1 to H17 corresponding to an arbitrary angle among the plurality of angle setting holes H1 to H17 formed in the driving plate 21, The driving plate 21 is rotated by an angle to rotate the air supply damping wave drive shaft 71 inserted into the rotational opening 12 integrated with the driving plate 21 by the angle.

Looking at the operation relationship with the angle control plate 42 for setting the rotation angle of the drive plate 21 as follows.

The case where the ball 45 of the angle adjustment plate 42 is located in the hole H2 which is a hole which rotates the drive plate 21 by 90 degrees among the angle setting holes H1-H17 of the drive plate 21 is demonstrated. Is as follows.

As shown in the figure, when the drive plate 21 is to be rotated by 90 °, the ball 45 of the bottom of the angle adjustment plate 42 is inserted into the 90 ° opening / closing setting hole H2 on the outside of the drive plate 21. Will be inserted.

When driving the output shaft 31 clockwise at this position, the gear 22 of the drive plate 21 engaged with the output shaft 31 rotates the drive plate 21 counterclockwise, and counterclockwise. The driving plate 21 and the angle adjusting plate 42 inserted thereon are rotated counterclockwise at the same time, and the second limit switch 19 is inserted into the second limit switch operating groove 43 formed in the angle adjusting plate 42. When positioned, the drive plate 21 stops rotating.

That is, when the second limit switch 19 is located in the operating groove 43 of the second limit switch 19 of the angle adjusting plate 42, the power to drive the motor 33 is cut off to stop the output shaft gear 31. As a result, the driving plate 21 is stopped.

In the above, when the driving plate 21 starts to rotate, the first limit switch 18 inserted into the first recess 23 of the driving plate 21 operates to detect the operation, and then rotates the second limit switch 18. When the limit switch 19 is inserted into the groove 43 of the angle control plate 42, the power is cut off to stop the rotation after a certain angle rotation.

When the drive plate 21 is rotated counterclockwise by the clockwise rotation of the output shaft gear 31 as described above, the damper drive shaft 71 inserted into the rotational hole 12 fixed to the drive plate 21 is rotated. By rotating the closed dam wave will be opened.

If the damping wave is closed, that is, if the damping wave is manually operated or checked, the return signal is inputted to the input terminal 72, and the output shaft gear 31 is rotated counterclockwise. ) And the angle adjustment plate 42 integrated therewith in a clockwise direction, and after the first limit switch 18 is rotated until the first recess 23 is positioned at the initial position, the power is cut off to output the gear shaft. Since the 31 stops, the driving plate 21 stops after being rotated by a predetermined angle clockwise.

When the driving plate 21 is rotated in the clockwise direction, the air supply dam wave driving shaft 71 is rotated in the clockwise direction to close the dam wave.

As such, the rotation of the driving plate 21 is sensed by the first limit switch 18 operated by the first recess 23 formed in the driving plate 21, and the angle is adjusted according to the position of the angle adjusting plate 42. Since the position of the second limit switch operating groove 43 formed in the adjustment plate 42 is changed, the rotation angle of the driving plate 21 can be arbitrarily set.

In the above description, the dam wave shaft is opened when the damp wave shaft is operated in a counterclockwise direction, and the dam wave is opened and closed when the clock is rotated in a clockwise direction. It can be seen that it has a structure that is closed when rotated in the direction.

As such, the present invention is provided with a configuration for operating a dam wave operating in reverse.

The driving plate 21 for inserting and fixing the lower end of the pivoting hole 12 integrally is attached thereto, and is integrally inserted into the lower part of the pivoting hole 12 by a ball 45 protruding from the bottom of the angle adjusting plate 42. The driving plate 21 to be fixed has a plurality of angle setting holes H1 to H17 on the surface thereof, and some of the driving plates 21 rotate the rotation angle of the driving plate 21 when the driving plate 21 is driven clockwise. The hole to be set and the drive plate to be driven in the counterclockwise direction are composed of a combination of holes to set the rotation angle of the drive plate 21.

That is, when the ball 45 protruding from the bottom of the angle adjusting plate 42 is located at the angle setting hole at the left end of the angle setting holes H1 to H17, the driving plate 21 is opened in the counterclockwise direction. When the ball 45 formed on the bottom surface of the angle adjusting plate 42 is located at the angle setting hole at the right end of the angle setting holes H1 to H17, the driving plate 21 is turned clockwise. Will indicate the maximum opening angle of.

When the driving plate 21 is rotated in the forward / reverse direction by the angle adjusting plate 42, the stopper 28 is fixedly inserted into one of the stop pin fixing holes S1 and S2 of the driving plate 21. The forward rotation, reverse rotation direction, and rotation range of the angle adjustment plate 42 are set by the stopper 28 inserted and fixed to the driving plate 21.

In this way, the stopper 28 inserted into one side of the stopper pin holes S1 and S2 of the driving plate 21 to set the forward and reverse rotation directions has a stopper guide groove 44 formed in the angle adjusting plate 42. It is located inside to set the rotation direction of the angle control plate 42 and the driving plate 21.

That is, when the driving plate 21 is to be adjusted in the counterclockwise direction, the stopper 28 is fixed to the first stopper hole S1 of the driving plate 21, and the driving plate 21 is clockwise. In the case of setting adjustment, the stopper pin 28 is fixed to the second stopper pin hole S2 of the drive plate 21.

The ball 45 protruding from the bottom of the angle adjusting plate 42 inserted into the angle setting holes H1 to H17 of the driving plate 21 is formed on the spring 51 inserted to the outside of the angle adjusting shaft 41. After setting the angle by the angle adjusting plate 42 and the driving plate 21 is not easily converted to the angle setting position by the spring elasticity, the angle adjustment of the end of the angle adjusting shaft 41 protruding on the upper surface of the main body 11 The hand tool is inserted into the shaft adjusting groove 46, thereby lifting and rotating the angle adjusting shaft 42 to set a desired rotation angle.

In addition, an angle guide 47 is provided at the end of the angle adjusting shaft 41, and the rotation hole 12 and the air supply dam inserted therein at an angle corresponding to the opening / closing angle scale 75 of the body surface indicated by the guide 47. The rotation angle of the wave drive shaft 71 can be known from the outside, and the angle adjustment shaft 41 is set by using a hand tool for the desired scale rotation angle.

The present invention relates to an air supply damper automatic switchgear that automatically opens and closes the air supply dam installed in a duct of a building. In the event of a fire, the fresh air is supplied from the air blower installed on the roof to the evacuation stairs of each floor through the air supply dam. To prevent choking.

However, the conventional air supply damping wave has only ON / OFF function in case of a fire, and it is only fully open or fully closed, but not partially open. Therefore, in the high floor close to the blower, the amount of air flowing in is high. Although it can be seen that the amount of air introduced is reduced, as in the present invention a plurality of angle setting holes (H1) in the drive plate 21 for rotating the rotating hole 12 for inserting the drive shaft for driving the air supply dam wave When the angle adjusting plate 42 and the driving plate 21 are set by inserting the ball 45 protruding from the bottom of the angle adjusting plate 42 and forming the angle adjusting plate 42 to the desired angle of rotation, the angle adjusting plate is formed. By the groove for operating the limit switch of the 42 and the driving plate 21, the rotating hole 12 is rotated exactly by that angle, and the air supply dam wave driving shaft inserted into the rotating hole 12 is rotated, and at an arbitrary angle. Accurately open the air supply dam at fire It is rotated by the set angle so that the opening angle of the air supply dam wave is arbitrarily adjusted, thereby adjusting the air inflow amount.

In other words, in the high floor close to the blower, the opening angle is decreased to reduce the flow velocity at high speed, and the air is introduced into the room at a suitable pressure. It is a very useful design to supply a large amount of changed air to the room so that fresh air supplied to the blower to all floors of the building can be introduced into the room at an even pressure.
