As shown in FIG. 5, when an inspector (not shown) operates the inspection tool 140 and wirelessly transmits an “inspection signal” from the inspection tool 140 to the communication unit 130 of the damper 101, the “inspection signal” is communicated. The data is transmitted from the transmission / reception unit 131 of the unit 130 to the control unit 105. The control unit 105 that has received the “inspection signal” transmits a “heating signal” to the heater 108, whereby the heater 108 generates heat and heats the temperature sensor 106.

  When it is detected that the temperature of the temperature sensor 106 has increased to a predetermined value (preset operating temperature) due to the heat generated by the heater 108, a “temperature increase signal” is transmitted from the temperature sensor 106 to the control unit 105.

  The control unit 105 that has received the “temperature rise signal” transmits an “operation signal” to the battery 109, whereby the operation voltage is supplied from the battery 109 to the solenoid 111, the solenoid 111 is activated, and the lock mechanism 113 is released. Therefore, the blades 102 of the damper 101 are instantly closed by the urging force.

  When the closing of the blades 102 is completed, an “operation completion signal” is transmitted from the control unit 105 to the transmission / reception unit 131 of the communication unit 130, and the communication unit 130 wirelessly transmits an “operation completion signal” toward the inspection tool 140. Therefore, the operator can confirm that the “operation is complete” by visually checking the inspection tool 140.

  Next, a return method for returning the blades 102 of the damper 101 that has been closed by the inspection work of the disaster prevention equipment 100 to the fully open state (normal state) will be described with reference to FIG. As illustrated in FIG. 6, when a “return signal” is wirelessly transmitted from the inspection tool 140 to the communication unit 130, the transmission / reception unit 131 of the communication unit 130 that has received the “return signal” transmits a “return signal” to the control unit 105.

  When the disaster prevention equipment 300 is inspected, the heater 108 is heated by transmitting an “inspection signal” from the inspection tool 140 or the disaster prevention panel 150 to the control unit 105 via the transmission / reception unit 131 of the communication unit 130, thereby causing the SMA fuse 301 to generate heat. Heat the heat sensitive part. When the temperature of the SMA fuse 301 rises to a set value due to the heating of the heater 108, the SMA fuse 301 is activated and the lock mechanism 113 is released, so that the blade 102 of the damper 101 is closed. The closing of the blades 102 of the damper 101 can be visually confirmed on the disaster prevention panel 150 or the inspection tool 140. The heater 108 is not particularly limited, and for example, a heating wire or a warm air generator can be used.

  Next, the disaster prevention equipment 400 shown in FIG. 9 includes a stepping motor 402 as the opening / closing mechanism 401 of the blade 102 of the damper 101. When the temperature in the air conditioning duct rises to the set value due to the heat at the time of the fire, the temperature sensor 106 senses it and a “blade closing signal” is transmitted to the control unit 105, and “operation” is performed from the control unit 105 to the battery 109. Signal "is transmitted. The battery 109 that has received the “operation signal” supplies an operation voltage to the stepping motor 402, and the stepping motor 402 quickly rotates to close the blades 102 of the damper 101.

  When the “blade closing signal” is transmitted from the temperature sensor 106 to the control unit 105, the “closed display signal” is wirelessly transmitted from the control unit 105 to the disaster prevention panel 150 via the transmission / reception unit 131 of the communication unit 130. An “operation indicator lamp” (not shown) provided on 150 is lit.

  When the “return signal” is wirelessly transmitted from the disaster prevention panel 150 to the communication unit 130, the “return signal” is transmitted to the control unit 105 via the transmission / reception unit 131 of the communication unit 130, and the stepping motor 402 is reversed from the above. And the blades 102 of the damper 101 return to the fully open state.

  When inspecting the disaster prevention equipment 400, when an “inspection signal” is transmitted from the inspection tool 140 or the disaster prevention panel 150 to the control unit 105 via the transmission / reception unit 131 of the communication unit 130, the stepping motor 402 rotates and the damper 101 is rotated. The blade 102 is closed. The closing of the blades 102 of the damper 101 can be visually confirmed on the disaster prevention panel 150 or the inspection tool 140.

  Since the disaster prevention equipment 400 uses the stepping motor 402 as the opening / closing mechanism 401 of the blade 102, the lock mechanism 113 using the fuse pin shown in FIG.

  Next, the disaster prevention equipment 500 shown in FIG. 10 is constructed by attaching the retrofit unit 20 to an existing fire prevention and smoke prevention damper (SFD) 10. The retrofit unit 20 detects the temperature in the battery 109 that can be charged by the regular power source 120, the transmission / reception unit 131 that can wirelessly transmit and receive signals between the disaster prevention panel 150, the limit switch 202, and the temperature in the air conditioning duct. Temperature sensor 106a. Although the temperature sensor 106a is provided in the damper 101, the temperature sensor 106a can be provided in the vicinity of the damper 101 in the air conditioning duct of the system in which the damper 101 is installed.

  The retrofit unit 20 is installed in the vicinity of the SFD 10, the terminal block 11 provided in the SFD 10 and the transmission / reception unit 131 of the retrofit unit 20 are connected by electrical wiring, and the electrical wiring between the fuse 201 and the lock mechanism 113. In addition, electrical wiring from the limit switch 202 of the retrofit unit 20 is connected. Further, the temperature sensor 106a and the transmission / reception unit 131 of the retrofit unit 20 are connected by electric wiring.

  In the disaster prevention equipment 500 shown in FIG. 10, when the temperature in the air conditioning duct rises to a set value due to heat at the time of the fire, the solder fuse 201 is melted and the lock mechanism 113 is released. Closed. Further, when the solder fuse 201 is melted, the limit switch 202 is activated, and a “closed display signal” is transmitted from the control unit 105 to the disaster prevention panel 150 via the terminal block 11 and the transmission / reception unit 131. The provided “operation indicator” (not shown) is lit.

  On the other hand, if the temperature sensor 106a detects that a predetermined time has elapsed after the temperature in the air conditioning duct is equal to or higher than a predetermined temperature, a fire has occurred and an operation signal is sent from the retrofit unit 20 to the SFD 10. Is supposed to send. Even when the SFD 10 is operated along this route, an operation signal is transmitted from the transmission / reception unit 131 toward the disaster prevention panel 150. The predetermined temperature may be set to, for example, an operating temperature of the solder fuse 201 (72 ° C. in a general air-conditioning duct) or more, and the predetermined time may be set to a time of 1 minute or more on the program, for example. it can.

  The operation of returning the blade 102 in the closed state to the fully opened state can be performed manually or by the motor 107. When using the motor 107, the motor 107 is operated by transmitting a “return signal” from the disaster prevention panel 150 to the control unit 105 via the transmission / reception unit 131 and the terminal block 11, and the blade 102 is returned to the fully opened state. Can do.

  In the case of the disaster prevention equipment 500, when it is activated by the occurrence of a fire (when the blade 102 is closed), it is necessary to replace the blown solder fuse 201 with a new solder fuse 201. Further, when the disaster prevention equipment 500 is inspected, “operation return” by remote operation from the disaster prevention panel 150 is possible, but the state of the solder fuse 201 needs to be visually confirmed.

  Since the disaster prevention equipment 500 can be constructed by installing the retrofit unit 20 in the vicinity of the existing SFD 10 and performing predetermined electrical wiring with the SFD 10, the installation work is easy. In addition, it is possible to reduce the burden of inspection work that is necessary only for the existing SFD 10. In addition, since the solder fuse 201 on the SFD 10 side is not essential, the retrofit unit 20 can also be applied to an existing SD (smokeproof damper) without a fuse. When applied to an SD (smoke damper) without a fuse, it is not necessary to replace the fuse, so that remote recovery after operation is possible. On the other hand, even when applied to the SFD 10, if the solder fuse 201 after the operation is replaced, the remote return after the operation is possible.

  Further, in the general SFD 10, even when the solder fuse 201 is not operated, it can be electrically operated by a route from the disaster prevention panel 150. Thus, since the damper 101 can be operated by either the solder fuse 201 or the temperature sensor 106a, the SFD 10 can be reliably operated when a fire occurs. Further, the retrofit unit 20 is not necessarily provided in a one-to-one relationship with the damper 101, and a plurality of dampers 101 can be connected to one retrofit unit 201 for each system of the damper 101.

  In addition, the disaster prevention equipment 100, 200, 300, 400, 500 described based on FIGS. 1 to 10 exemplifies the disaster prevention equipment of the present invention, and the disaster prevention equipment of the present invention is the disaster prevention equipment 100, 200, It is not limited to 300,400,500.

  The disaster prevention equipment of the present invention can be widely used in the field of construction industry as one of disaster prevention means installed for preventing fire damage expansion in various buildings.
