Description

System cutoff damper fireproof sector used the temperature fuse}

The present invention relates to a temperature-sensitive metal temperature fuse for operating the fire-fighting equipment and fire fighting apparatus, and more particularly to the fire zone by operating the temperature-sensitive metal temperature fuse by the detection operation and the smoke detector signal of the elevated temperature change around the fire. The present invention relates to a fire protection zone damper blocking device using a thermal-metal thermal fuse that prevents smoke from spreading out or spreads flames so that early fire or rapid evacuation of a person in a building and protection of property and life can be protected.

In general, when a fire occurs, a fire damper and a smoke damper which prevents the spread of fire and smoke are operated, or a sprinkler that suppresses the fire, an automatic fire extinguishing facility, an automatic fire extinguisher, and the like operate. However, due to the nature of fire, if a fire occurs, heat is generated by flame after a few minutes after the smoke is generated first. Thus, when the fire occurs, smoke occurs first rather than heat, so if smoke spreads before a person evacuates, there is a problem in that loss of sense of direction due to lack of vision and loss of life due to difficulty in breathing by toxic gases.

In case of fire, sprinkler, fire door, fire shutter, fire damper, and ventilation duct are operated by smoke, but most of them are operated by temperature sensor by heat. In case of fire, first, smoke including toxic gas spreads first, and fire-fighting equipment and fire-fighting equipment are operated by heat detection, so that thick soot containing dust is attached to indoor equipments, interiors, wires, and electronic circuits. And a fatal problem occurs that the fire fighting device does not work.

Therefore, after the fire extinguish, new equipment and wallpaper, which are burned or burned, must be replaced.In addition, new electronic and electrical devices connected to the wires to supply electrical signals and power must be newly installed. There is a problem that economic losses are aggravated.

Looking at the prior art in this field, a fuse that is fixed by a fuse is attached to the upper part of the fire blocking shutter duct of the registered utility model notification No. 0192913 (prior art 1), the fuse is disconnected when reaching a certain temperature. It is to provide a fire blocking shutter that blocks the flow of air in case of fire by enabling the shutter to operate.

That is, the present invention is to construct a conventional duct (2) to allow air to move between the partitions (1),

A pair of guides 3 are installed in the duct 2 to form a slide hole 4, and a foldable shutter 5 is positioned on the slide hole 4 to fix the upper side on the duct 2. And attaching the hooks 6 and 7 to the guide 3 and installing a fuse 8 detached at a temperature of about 70 ° C between these phases so that the shutter 5 can be folded and fixed. It can be seen that the connecting ring 6 allows the pin 9 to be coupled to the guide 3 so that the fuse can be detached when the temperature rises in a fire or the like to block the inside of the duct. 9b)

However, the prior art 1 is configured to separate the fuse (8) holding the guide link in order to operate the collapsible shutter (5) installed in the duct at about 70 ℃ fire occurs so that the air rises to 70 ℃ flame At this time, there is a problem that the smoke spreads to each disaster prevention zone even though the fuse is separated and the shutter is lowered to block the smoke since the smoke has already spread.

As another prior art, the fire damper of Utility Model Publication No. 1988-0000937 (Prior Art 2) has a shield plate (1) arranged horizontally on both side walls of the outer cylinder and a spring on one axis of the shield plate. (2) In the well-known firearm damper, which hangs the lead ring (3) on the other shaft, the same outer cylinder (4) (5) is divided into two and formed into a 'B' shape, but each side end of each outer cylinder is required (6). And the mounting portion 7, and the hanging jaw (8) and the threaded hole (9) and the upper surface is formed with a locking jaw (10) by combining the outer cylinder (4) (5) with each other is composed of a damper It can be seen (see Fig. 10).

In order to operate the shield plate installed in the damper, the prior art 2 is installed so that the spring is pulled on one side, and the other side is hooked to prevent the damper passage from being blocked by the pulling force of the spring and keeps the opening state. It is made up all the time. In the prior art 2 configured as described above, when the lead ring 3 is melted and separated by an elevated temperature in a fire, the shield plate blocks the damper passage by the pulling force of the spring, but this time is also a time point at which the lead ring is separated by heat. Since the smoke spreads due to the fire and is melted by the elevated heat, the prior art 2 also does not operate quickly, but it takes time to reach a predetermined temperature, and thus it takes more than 2 minutes for the shield to operate. There is a problem with failing.

As described above, even if the temperature fuse has a fire and the surrounding temperature reaches the temperature necessary for the operation of the temperature fuse, a considerable time is delayed until the temperature fuse absorbs enough heat for operation and operates. Including smoke spreads to prevent the evacuation quickly and the fire is already spread to the vicinity of the fire fighting equipment firefighting equipment and firefighting equipment is operating, there is a problem that it is difficult to suppress the initial fire or spread.

The present invention is to solve the problems as described above, to operate the blocking device installed in the fire protection damper, smoke control damper, ventilation damper (hereinafter referred to as "fire damper") installed in the ceiling floor wall of the building for each protection area. A molten metal tube made of molten material is installed between the outer tube and the inner tube of the base fuse of the temperature fuse while the thermosensitive metal temperature fuse is operated at the detection of either the thermal temperature or the smoke. A large number of heat collecting plates are installed to absorb early to detect horizontal heat and vertical heat in the early stage of fire, and to separate them in the shortest time at a predetermined temperature. Thermal fuses to protect more people and property from fire To provide any good fire protection zone damper blocking device is aimed.

To achieve the object of the present invention

In the temperature fuse for operating the fire fighting equipment and fire fighting equipment in case of fire,

The appearance of the base tube is characterized in that the movable shaft of the solenoid 17 is fitted in the fixing hole (16a) can be separated by a smoke detection signal in the event of fire.

  The temperature fuse 10 of the present invention configured as described above operates fire prevention damper 20, ventilation damper, and smoke removal damper early by detecting smoke detection or fire temperature in case of fire, thereby extinguishing the fire and causing injury and re-injury. In particular, it is possible to prevent the delayed operation of the fire fighting equipment and the fire fighting equipment due to the late separation of the fuse in case of fire.

Therefore, the present invention provides a temperature-sensitive metal temperature fuse to the fire damper for operating the fire-extinguishing block and fire extinguishing device. It is to provide a fire protection zone damper blocking device using a thermosensitive metal temperature fuse 10 to be controlled to play an important role in the initial fire suppression and spread prevention.

The present invention provides a thermal shock metal short fuse for shortening the operation time of the fire damper in case of fire to be separated by the solenoid operation by the separation or smoke detection by the temperature during the fire to reduce the fire zone closing time of the fire damper ( It is set to be separated at the temperature of 67 ℃ or 72 ℃, respectively, according to the regulations of firefighting: called the predetermined temperature) If the fire occurs within 15 to 20 seconds, the fire damper is shut off more quickly so that the smoke is different. By preventing the spread of fire, the human life and property can be protected from fire.
