1 shows a separate hybrid fire safety system 1 according to an embodiment of the present invention.

The system 1 according to the present invention may include a disaster occurrence detection means disposed in a ceiling, a wall surface, or the like in the space 3 to detect the occurrence of a disaster. The disaster detection means senses the occurrence of a disaster and transmits a signal to the control unit 28, and the control unit 28 can select a facility to be operated next in accordance with the type of disaster.

For example, the disaster occurrence detecting means can be operated by a sound sensor that detects a noise of a predetermined decibel or more, for example, by a vibration sensor that detects vibration caused by natural disaster such as an earthquake, explosion, collapse or the like And can be operated by an image sensor which senses a disaster as an image and can be operated by the fire occurrence detector 2. [ It may also be a combination of the illustrated sensors or detectors.

For example, the disaster occurrence detection means may be a fire occurrence detector 2. The fire occurrence detector 2 senses the occurrence of a fire and transmits a signal to the control unit 28 and activates the alarm apparatus 2a.

The specific type of fire detection sensor 2 includes all known fire detection sensors. For example, a fire detector that detects the occurrence of a fire due to a temperature change may be a differential fire detector that operates when the room temperature rises rapidly, or a warm fire detector that operates when a certain temperature is reached. In addition, for example, the fire occurrence detector 2 is a smoke detector that operates by detecting smoke. The fire detection sensor 2 is an ionization type detector that uses a change in ion current due to smoke or a photoelectric type detector that uses a change in incident light amount by smoke Lt; / RTI > In addition, the fire occurrence detector 2 may be a flame detector such as an ultraviolet detector.

The fire occurrence detector 2 may be installed alone or in combination with one or more of the above-described detectors, and may include one or more detectors. In addition, the fire occurrence detector 2 of the present invention can be installed in a single space, such as an area of the space, according to design requirements, and the installation place is not limited to a wall surface, a ceiling, and the like.

The present invention relates to a fire extinguishing module (14) for extinguishing a fire, comprising a fire extinguishing agent storage container (4) in which an extinguishing agent is stored and a fire extinguishing agent (8) for injecting the extinguishing agent into the space (3). The extinguishing agent supply pipe 6 is provided with a fire extinguishing valve 10 controlled by the control unit 28 and the extinguishing agent spraying means 8 is installed on a wall surface or a ceiling in the space 3.

The control unit 28 controls the extinguishing agent to be injected into the space 3 in response to the signal received from the fire occurrence detector 2. In an embodiment of the fire suppression in the present invention, the fire extinguishing valve 10 is opened when the control unit 28 operates the fire extinguishing valve driver 12, for example, for driving the fire extinguishing valve 10. When the extinguishing valve 10 is opened, the extinguishing agent flows from the extinguishing agent storage container 4 and is supplied into the space 3 by the extinguishing agent spraying means 8.

The extinguishing agent according to the present invention may be any known extinguishing agent, particularly preferably a compressed gas, and more preferably, it may be carbon dioxide. The extinguishing agent spraying means 8 according to the present invention includes all known available spraying means capable of uniformly spraying the extinguishing agent in the space 3. [ In addition, the extinguishing valve 10 according to the present invention includes all available valves known to those of ordinary skill in the art, and may in particular be a selection valve.

Although FIG. 1 shows one or a certain number of elements, this is for simplification of the drawings, and each element can be used singularly or in plural, considering various factors in design.

1 and 2, the individual hybrid fire safety system 1 according to the present invention can be applied to a case where an emergency exit is not opened due to breakage due to an external force such as collapse of a building or malfunction of an exit And an airbag module 24 that can forcibly open the door of the exit. One or more airbag modules 24 may be embedded in the doors of the exit 16. [

2, the airbag module 24 according to the present invention includes an inflating gas generating means 20 and an airbag 22. The inflating gas generating means 20 receives a signal from the control unit 28 to generate an inflator for inflating the airbag 22, whereby the airbag 22 is operated to open the door. Specifically, for example, when the inflation gas generating means 20 receives a signal from the control unit 28, a chemical reaction is generated in which the nitrogen or argon gas is rapidly generated by the igniter, whereby the air bag 22 Is expanded. Thus, the emergency exit port 16 is forcibly opened, the escape space can be secured, and when the surrounding environment is difficult to detect visually and audibly due to a power failure or the like, As shown in FIG.

The inflation mechanism of the airbag 22 includes all mechanisms well known in the art and may be modified to suit the system according to the present invention. For example, in an airbag system used in the automotive field, an instruction of inflation of the airbag is transmitted by a collision detection means, which receives information mainly from an accelerometer or the like. In the system according to the present invention, the collision sensing means mainly used in the automobile field can be used. However, in order to cope with various possible disasters, a smoke sensor, a collision sensor, a vibration sensor, It would be appropriate to design the airbag to be automatically inflated by the various types of sensing means.

The airbag 22 according to the present invention may also be arranged such that one or more airbags may be arranged in a line along the longitudinal direction of the doorway of the exit 16 and one or more airbags may be installed in the thickness direction of the doorway, At least one airbag along the length direction and at least one airbag along the thickness direction. It is possible to install one or more airbags at the entrance of the exit in order to prevent the malfunction of the airbag and / or to take into consideration the strength, the budget, etc. of the material of the door.

Further, as shown in FIG. 5A, grooves can be formed on the inner side of the door so that the doors of the exit of the emergency exit can be more easily opened due to the expansion of the airbag. For example, the groove on the inner side of the door can be freely formed according to the installation position of the airbag, and can be formed along the central portion of the door. There is no particular limitation on the form in which the groove is formed in the door. Figures 5A and 5B show an exemplary form.

The portion where the groove is not formed is kept attached to the door despite the operation of the airbag, so that it is possible to prevent the damage of the person who may be blown into the space due to the operation of the airbag.

It is also preferable to arrange means for visualizing the airbag opening notification, for example, an alarm, a fluorescent sign, etc., around the exit so as to prevent people near the exit when the airbag is opened from being injured by the opening of the airbag something to do. These airbag opening notifications may be controlled by the control unit to be performed approximately several seconds to several minutes before the airbag is opened.

The airbag according to the present invention can be installed at each door of an installed exit, and can be installed with fewer or more water than necessary.

The hybrid type fire fighting safety system 1 according to the present invention may include at least one fire exit opening detecting means 26 for detecting whether or not the fire exit is opened. The emergency exit opening detection means 26 senses whether or not the emergency exit is opened and transmits a signal to the control unit 28 whether the door is open or closed. The control unit 28 controls the inflation gas generating means 20 of the airbag module 24 to open the airbag 22 when the control unit 28 receives the closing signal of the exit port 16 as described above.

For example, the emergency exit opening detecting means 26 may be any well-known sensor for detecting whether doors and windows are opened or closed. Preferably, the emergency exit opening detecting means 26 may be installed at a door opening of the emergency exit door, The pressure sensor may be a pressure sensor.

1, a control unit 28 for controlling the opening and closing of the oxygen supply valve 36 supplies an oxygen supply valve opening signal to the oxygen supply valve driver 40 The oxygen supply valve 36 is opened and the oxygen stored in the oxygen storage means 32 flows into the oxygen supply pipe 34 and is supplied into the space 3 through the oxygen supply head 42. Thereby, the people in the space 3 can secure the time required for escape.

In addition, the carbon dioxide level sensing means 30 for transmitting a signal to the control unit 28 can determine whether or not oxygen supply is necessary. For example, after the fire is extinguished, the carbon dioxide level sensing means 30 installed in the space 3 measures the carbon dioxide concentration in the space 3. The control unit 28 compares the carbon dioxide concentration tolerance value which does not adversely affect human breath preset in the control unit 28 and the carbon dioxide concentration sensed by the carbon dioxide level sensing means 30 and determines whether oxygen supply is necessary, 3).

The above-mentioned oxygen supply is intended to allow time for the people in the space to escape and enable survival if the exit is not opened.
