Description

Firewall safe motor controller {Fire wall safe controller}

The present invention relates to a safety control device for a firewall driving motor, and more particularly, to a safety control device for a firewall driving motor which prevents the operation of the forced raising button of the control device without pressing the reset button to enable a stable function of the firewall.

In general, the firewall is used to block the fire by section in the event of a fire so that the fire does not spread anymore. For example, as shown in FIG. 1, the guide rail 1 installed vertically on the walls on both sides such that the firewall is guided, the firewall 2 moving up and down on the guide rail 1, and the firewall 2 are wound up and down. A shaft 3, a motor 5 for rotating the shaft 3 by a pulley or a chain 4 or the like, a drive motor controller 10 for controlling the driving of the motor 5, and the motor 5 ) And a firewall box 5 'that houses the shaft 3.

FIG. 2 is a perspective view illustrating main parts of a coupling configuration with a driving motor controller 10 which controls the driving of the motor 5. FIG. 3 is a horizontal sectional view of FIG. 2, which blocks rotation of the motor 5 and causes a fire. The drive lever 6 to be driven only at the time, and the drive motor controller 10 to enable the rotation of the motor 5 by pushing the drive lever 6 to the push lever 15 in case of fire. The driving lever 6 is shot with a spring 7 and configured to be guided by an electromagnet 8 serving as a guide so as to be returnable upon operation of the push lever 15.

FIG. 4 is a front view in which the cover of the drive motor controller 10 shown in FIG. 2 is omitted, the drive motor controller 10 includes a first solenoid 12 receiving DC power output from a controller in the event of a fire; The base lever 14 rotates counterclockwise around the first hinge 13 during the telescopic operation of the first solenoid 12, and the hook spring is normally coupled to one end of the base lever 12 and the ball spring is released when the hook is released. 16 is pushed in the direction of the arrow by the force of the force coupled to the solenoid lever 18-1 to form a state of Fig. 5 and the push lever 15 is provided when the firewall 2 in the extended state of the push lever 15 The second solenoid 1 8 which expands and contracts with the charging power to return the push lever 15 to perform the brake function and the second solenoid by turning off the contact of the micro switch 17 when the push lever 15 is extended. Second hinge to turn off the applied power of 18 It comprises a micro switch lever 20 to rotate around the 19). The first solenoid 12 expands and retracts the solenoid lever 12-1 in which the tip stayed at the stopper 12-2 to rotate the base lever 14 counterclockwise. 15-1 is a hook groove, which functions to fix the upper end of the base lever 14. Numeral 16-1 is a lever guide for supporting the bullet spring 16 and guiding the solenoid lever 18-1. (14-1) is a spring installed at the lower end to maintain the initial state by pulling the force lever 14 in the clockwise direction, (20-1) one end of the first hinge 13, the other end of the micro switch lever ( 20 is a spring provided to the micro switch lever 20 to provide a tension force to rotate in the counterclockwise direction.

FIG. 6 is a diagram illustrating a circuit configuration of a general driving motor controller 10. The first solenoid 12 which receives an output through the output terminals a1 and a2 of the firewall controller 2-1 and turns on the contact s1. ), The capacitor (C1) is charged when the contact (s1) is turned on, in conjunction with the micro-switch (17), is normally on and off during operation, and operates in turn on in conjunction with the operation of the first solenoid (12) The brake function of the motor 5 is released by the micro switch 17 having the micro switch contacts bb1 and bb2, the push lever 15 extending and the micro switch 17 are actuated, so that the firewall 2 is lowered and lowered. When the contact point (cc) to be turned on in conjunction with the output signal at the completion point is turned on to receive the power charged in the capacitor (C1) to block the rotation of the motor (5) to prevent damage to the lower end of the firewall (2) Consisting of a second solenoid 18 enabling the function It is.

The general configuration as described above forms a wound state when there is no fire due to the characteristics of the initial firewall. Then, when a fire occurs, the firewall controller 2-1 shown in FIG. 6 recognizes the output of the sensor that recognizes the fire, and the first solenoid 12 of the drive motor controller 10 is opened through the output terminals a1 and a2. Drive (FIG. 5 state). Then, the contact s1 is turned on, and since the contacts bb1 and bb2 are normally turned on, the power is charged to the capacitor c1 instantaneously. The second solenoid 18 is turned on by the contact (cc) function which is turned on in response to the signal output from the motor 5 by the firewall descending, and when the push lever 15 is pulled out, the initial state is stopped and the rotation of the motor is stopped. To prevent damage to the bottom of the firewall (2).

That is, when the first solenoid 12 operates in a fire, the solenoid lever 12-1, which is extended so as to contact the end of the stopper 12-2, is pulled out, and accordingly, the lower end of the solenoid lever 12-1 is pulled out. The combined base lever 14 rotates counterclockwise around the first hinge 13 in the center, and hooks at the hook groove 15-1 of the push lever 15 through an upper end of the base lever 14. The coupled push lever 15 is released by the hook and the push lever 15 is extended by the action of the spring spring 16. As the push lever 15 extends, it means that the motor shaft 5-1 can be freely rotated by pushing the drive lever 6 which has pushed the motor shaft 5-1 to perform the brake function as shown in FIG. 3. It means that the firewall goes down. As the push lever 15 extends as described above, the micro switch lever 20 abutting against the tapered protrusion 15-2 of the push lever 15 rotates counterclockwise about the second hinge 19. When the contact is turned on, charging is instantaneously performed in the capacitor c1 shown in FIG. In this state, when a signal is output from the motor 5 designed to send a signal at a position where the firewall is lowered, the contact point cc shown in FIG. 6 is turned on so that the power charged in the capacitor c1 is supplied to the second solenoid 18. ), Which pushes the push lever 15 back and forth, thereby pushing the drive lever 6 with the elastic force of the spring spring 7 coupled to the electromagnet 8 inside the motor 5, FIGS. As shown in FIG. 3, the driving lever 6 is moved from the dotted line to the solid line to block rotation of the motor shaft 5-1.

However, in this method, when the charge of the capacitor c1 shown in FIG. 6 is discharged due to external noise or foreign matter, the operation of the second solenoid 18 becomes unstable and the brake function of the firewall 2 is lost. As a result, if the side door of the firewall is not crushed and opened due to the damage of the firewall, it may cause a fire.

Meanwhile, the general firewall driving device detects a fire through the sensor S as shown in FIG. 7, and as a detection output through the firewall control unit 2-1 based on the detected signal (through the output terminals P1 and P2). The direct current output, for example 24 volts, activates the first solenoid 12 (in this case the first micro switch 17-1 which constitutes the micro switch 17 is in the normal on state), so that the firewall It descends and acts as a firewall. However, if you want to stop the operation of the firewall due to obstacles or unstable events while the firewall is falling, stop the operation of the control unit (2-1) even though the sensor (S) is being detected by a reset button (not shown), Pressing the rising button 31 allows the second solenoid 18 to operate to allow the motor 5 to rise. However, users do not press the reset button in panic or inexperienced operation and immediately press the forced rising button 31. Since the reset button is not pressed, the DC output is applied to the output terminals P1 and P2 through the firewall control unit 1 so that the first solenoid 12 is driven (the first micro switch 17-1 is in the off state from the normal on state. The second micro switch 17-2 is turned on from the normal off state. The push lever 15 is extended to enable the driving of the motor 5 (the lowering of the firewall), but the forced rising button 31 ), The second solenoid 18 is activated and the micro switch 17 is operated in the normal state (the first micro switch 17-1 is in the normal on state, and the second micro switch 17-2 is operated). Drives the first solenoid 12 in a normal off state. Then, the push lever 15 again extends to the elastic force of the spring 16, and accordingly, the micro switch 17 is operated in the normal state, and in this state, if the user keeps pressing the forced raising button 31 again, 2 The solenoid 18 is repeated to operate again. Therefore, the first and second solenoids 18 are repeatedly operated and burned or damaged.

The present invention is to solve this problem, an object of the present invention is to provide a firewall safety control device to protect the control device to prevent the forced rise without pressing the reset button for the firewall drive to the drive control device of the general type firewall. I will.

To this end, the present invention allows the first solenoid to operate when the fire is detected to release the push locking of the push lever to enable the driving of the motor to lower the firewall, and the second solenoid to expand and contract the push lever to raise the motor when the lowering is completed. And a micro switch that is turned on when the first solenoid is driven and serves as a switch for applying power for driving the second solenoid. When the second solenoid is driven in conjunction with the reset button, the motor is raised by a forced rising button operation. In the general type firewall control device, a relay coil is added to both ends of the output terminal of the firewall control unit in parallel, and a line in which the AC power is applied to the second solenoid through a forced rising button is connected to the normal sole state driven by the relay coil. Configure the contacts to be connected.
