Emergency exit guidance device provided on a cable tray for apartment complexes {EMERGENCY EXIT GUIDE APPARATUS WITH CABLE TRAY FOR APARTMENT HOUSE}

The present invention relates to an emergency exit guidance device provided in an electric wire tray for an apartment complex. More specifically, the present invention relates to an emergency exit guidance device installed on the ceiling of an underground space of an apartment complex and on which power supply lines, internet optical cables, and other signal lines are wired. An emergency exit guidance device provided in an apartment wire tray that can easily guide evacuees to the emergency exit in the event of an emergency such as a fire, and can supply power and transmit/receive signals using the power supply and signal lines wired to the wire tray. It's about.

In general, an emergency exit is an exit that allows evacuees within a building to quickly evacuate in the event of a fire or other emergency.

An emergency exit guidance device is provided at the top of this emergency exit. As shown in Figure 1, the emergency exit guidance device includes a case installed in the upper area of the emergency exit or a hallway, a lamp provided in the case to emit light, and the letters and arrows for 'emergency exit' due to the emission of a fluorescent lamp on the front of the case. It consists of a light-transmitting panel that emits light.

However, this general emergency exit guidance device had a problem in that it was difficult for evacuees in the building to identify the emergency exit guidance device in the event of a fire or other emergency because the light from the fluorescent lamp was rapidly reduced as the light transmitted through the light transmitting panel.

To solve these problems, various emergency exit guidance devices that have improved the identification of emergency exit guidance devices have been developed.

As a conventional technology for emergency exit guidance devices, an emergency exit guidance light is disclosed in Korea Registered Utility Model Publication No. 20-329023. The emergency exit guide light of the prior art improves visibility by illuminating the thickness of a transparent or translucent sign board with a plurality of light emitting diodes on at least one side of which a guide sign guiding the emergency exit is carved or printed. However, in the event of a fire, there was still a problem of poor visibility due to the smoke generated.

As another prior art, Republic of Korea Patent Publication No. 10-0734475 discloses an emergency exit guidance light with a built-in guidance speaker. The prior art emergency exit guidance light with a built-in guidance speaker has an emergency exit guidance light installed on the floor of the building and is equipped with a voice output unit that informs the location of the emergency exit by voice, allowing people in the building to recognize the location of the emergency exit by hearing rather than by sight. . However, since the emergency exit guidance light was installed on the floor of the building, it was inconvenient to keep it clean at all times to ensure visibility, and it was difficult to recognize the location of the emergency exit by using voice guidance to people visiting the building for the first time. .

As shown in Figures 2 to 4, the emergency exit guidance device 200 provided in the electric wire tray for an apartment complex according to the present invention is installed on the wire tray 100 and is used in the underground space (S) including the parking lot of the apartment complex. In the event of a disaster such as an earthquake, fire, or flood, a laser beam is used to detect the emergency exit (E) location and the escape route (guide beam) to the emergency exit (E) on the floor, walls, and/or ceiling of the underground space (S). This is to ensure that evacuees can easily escape. That is, the control module 240 operates the laser beam generator 234 based on the detection signal from the detection unit 242 to generate a guide beam (L) to guide evacuees to the emergency exit (E) in the underground space (S). It is intended for irradiating the floor, wall or ceiling. In addition, wiring for power and data transmission and reception required for the operation of the emergency exit information device 200 is made in the wire tray 100, or wiring in another space is performed by using wires or data cables wired in the wire tray 100. This is to make it unnecessary.

This will be explained in more detail.

As shown in Figures 2 to 4, the emergency exit guide device 200 provided in the electric wire tray for an apartment complex according to the present invention has a coupling hole 212 formed on the front, and is located in an underground space (including the parking lot of the apartment complex) It is electrically connected to the server 300 by a coupling support 210 mounted on the side rail 110 of the wire tray 100 installed in S) and a data cable W wired to the wire tray 100. A connection port 220 is configured to enable data transmission and power supply and is provided on the coupling support 210, and a locking piece 232A is provided on the back of the case 232 to be detachably fastened to the coupling hole 212. It is formed and is equipped with a laser beam generator 234 on the front, a guidance module 230 with a connection terminal 236 connected to the connection port 220, and installed in the wire tray 100 in the underground space (S ) and transmits the detection signal detected by the detection unit 242 to the server 300 and operates the laser beam generator 234 based on the detection signal to detect smoke, heat, and flame generated from ). It includes a control module 240 that is configured to form an escape path with a laser beam and includes a control unit 244 built into the guidance module 230.

The coupling support body 210 is for mounting the case 232 of the guide module 230 on the wire tray 100, and as shown in FIGS. 2 to 5, there is a locking piece of the case 232 on the front ( A coupling hole 212 is formed so that 232A) is inserted. The coupling hole 212 is formed in a horizontal direction in the insertion portion 212A so that the insertion portion 212A formed larger than the locking piece 232A and the locking piece 232A inserted into the insertion portion 212A move in the horizontal direction. The extended moving part 212B and the locking part 212C extending directly downward from the end of the moving part 212B so that the locking piece 232A moved to the end of the moving part 212B moves directly downward and is caught. ).

And, as shown in FIGS. 4 and 5, locking grooves 212C-1 are formed concavely on both sides of the inner surface 212C-2 of the locking portion 212C. This locking groove 212C-1 is used to prevent the locking piece 232A from being released arbitrarily by engaging the locking protrusions 232A-1 protruding from both sides of the inner surface of the locking piece 232A. At this time, the locking groove 212C-1 is formed with a curved edge, and the locking protrusion 232A-1 is also formed in a curved hemispherical shape, so the locking protrusion 232A-1 is inserted into the locking groove 212C-1 without interference. It can be. In addition, since the middle part of the locking piece 232A is integrated with the case 232 and both ends are free ends, the locking piece 232A generates elasticity when the locking protrusion 232A-1 is inserted into the locking groove 212C-1. Since it is deformed while being pressed, the locking protrusion 232A-1 can be elastically inserted into the locking groove 212C-1.

The coupling support body 210 has coupling ends 214 formed by bending both ends, and is detachably mounted on the side of the side rail 110 using bolts or the like.

The connection port 220 is electrically connected to the server 300 provided in the management room of an apartment complex, etc., and is connected to the server 300 by a data cable including a power supply line wired to the wire tray 100. In this way, since the access port 220 is electrically connected to the server 300 by a data cable, etc. wired to the wire tray 100, the wiring for connecting the access port 220 to the server 330 is wired to a separate location. Since there is no need to do so, the installation and construction of the emergency exit guidance device 200 according to the present invention can be carried out quickly and easily, as well as the construction period can be shortened and a lot of costs can be saved.

And the connection port 220 is electrically connected to a plurality of detection units 242 installed on the wire tray 100 by a data cable. That is, each detection unit 242 and server 300 are connected to the connection port 220 by a data cable.

The connection port 220 applied to this embodiment may be a USB PORT (Universal Serial Bus Port) capable of transmitting data and supplying power.

This connection port 220 is provided on the front or side of the coupling support 210.

The guidance module 230 is configured to be connected to the connection port 220 and electrically connected to the server 300 and the detection unit 242, is installed on the coupling support 210, and is detachable from the coupling hole 212. It includes a case 232 with a locking piece 232A formed on the back, a laser beam generator 234 provided on the front of the case, and a connection terminal 236 configured to be connected to the connection port 220. It is composed by:

The case 232 forms an internal space so that the laser beam generator 234 and the control module 240 are built in, and a locking piece 232A for attachment and detachment from the coupling hole 212 is formed on the rear side. The middle part of the locking piece 232A is formed integrally with the case 232, and both sides of the middle part have a predetermined distance from the back surface. The gap is formed to be equal to or slightly larger than the thickness of the plate forming the engaging portion 212C. This is to ensure that the locking piece 232A is press-fitted into the locking portion 212C to prevent random separation.

And, as shown in FIGS. 4 and 5, locking protrusions 232A-1 are formed to protrude on both sides of the inner surface of the locking piece 232A corresponding to the locking groove 212C-1 of the locking portion 212C. This ensures that when the locking piece 232A is located in the locking portion 212C, each locking protrusion 232A-1 is inserted into the locking groove 212C-1 to prevent the locking piece 232A from being released arbitrarily.

Meanwhile, among the attached drawings, FIG. 6 is a partially enlarged cross-sectional view showing another embodiment of the locking piece and coupling portion shown in FIG. 5.

As shown in FIG. 6, the locking piece 232A and the locking portion 212C according to another embodiment have locking pieces 232A on both sides of the case 232 corresponding to the inside of the locking piece 232A. It is the same as the above-described embodiment except that magnets 232B are provided to generate magnetic force so that when inserted into the locking portion 212C, the hooked state is maintained and arbitrary separation is prevented.

In this way, the case 232 is provided with a magnet 232B, so that when the locking piece 232A is inserted and caught in the locking portion 212C of the coupling hole 212, the locking portion 212C is moved by the magnetic force of the magnet 232B. Since it remains in close contact with the inner wall, random separation can be prevented.

At this time, the magnet 232B may be applied to the locking piece 232A and the locking portion 212C in which the locking groove 212C-1 and the locking protrusion 232A-1 are formed.

The laser beam generator 234 built into the above-described case 232 is configured to radiate a laser beam simultaneously to the wall, floor, and/or ceiling of the underground space (S), but is configured to radiate a laser beam to the wall. The generator, a laser beam generator for irradiating the floor, and a laser beam generator for irradiating the ceiling may be separately provided and operated simultaneously.

The connection terminal 236 is configured to be connected to the connection port 220 and is electrically connected to the control module 240 through a data cable.

As shown in FIG. 9, the control module 240 is configured to control the operation of the laser beam generator 234 based on the detection signal detected by the detection unit 242 and transmit a monitoring signal to the server 300. It is built into the case 232 of the guidance module 230, and is installed on the wire tray 100 to detect smoke, heat, and flame generated in the underground space (S), a detection unit 242, and a detection unit ( It includes a control unit 244 configured to transmit the detection signal detected by 242 to the server 300 and operate the laser beam generator 234 based on the detection signal to form an escape path into a laser beam.

As shown in FIGS. 2 to 9, the detection unit 242 includes at least one smoke detector 242A installed on the wire tray 100 to detect smoke, and at least one smoke detector 242A installed on the wire tray 100 to detect smoke. It consists of at least one heat detector 242B for detecting and at least one flame detector 242C installed on the wire tray 100 to detect a flame.

Each smoke detector 242A, heat detector 242B, and flame detector 242C are installed at various positions on the wire tray 100 and are electrically connected to the connection port 220 by a data cable.

Meanwhile, the detection unit 242 is installed on the wire tray 100 to detect a change in the distance between the floor of the underground space (S) and the wire tray 100, as shown in FIG. 8, and transmit it to the control unit 244. It further includes a submersion detection sensor (242D). That is, the flooding detection sensor 242D is configured to detect that the distance L1 between the floor and the wire tray 100 is reduced when the underground space S is flooded and filled with water, and transmits this to the control unit 244. That is, when the water level rises as water flows into the underground space (S) and the distance (L2) between the water surface and the wire tray (100) becomes shorter than the previously stored distance (L1) between the floor and the wire tray (100), the control unit 244 ) is detected by flooding in the underground space (S).

The submersion detection sensor 242D may be configured to measure the distance to an object by irradiating a laser or sound wave and receiving the reflected laser or sound wave.

Meanwhile, the control unit 244 compares the distance change data received from the flood detection sensor 242D with the previously stored distance data, and when it is determined that water is rising in the underground space (S), the control unit 244 sends the flood detection data to the server 300. It is configured to transmit to and operate the laser beam generator 234 to generate a guide beam (L).

In this way, when flooding occurs in the underground space (S), the flooding detection sensor (242D) of the detection unit (242) quickly detects it, transmits it to the server (300), and radiates a guide beam (L) for evacuation. As a result, it is possible to quickly detect emergency evacuation situations due to flooding as well as fire in the underground space (S) and guide evacuees to quickly and easily evacuate to the emergency exit.

The above-described control unit 244 is electrically connected to the detection unit 242 and the server 300 as the connection terminal 236 is connected to the access port 220 to transmit and receive data and receive power.

As shown in FIGS. 7 to 9, the control unit 244 transmits the detection signal detected by the detection unit 242 to the server 300 and generates a laser beam based on the detection signal detected by the detection unit 242. It is configured to form an escape path as a laser beam by operating (234), and may further include a memory and a timer for storing reference data, and operates and controls speakers, warning lights, etc. provided in the case 232. It can be configured to do so.

In particular, the control unit 244 may control the laser beam generator 234 so that the guide beam (L) forming the escape route blinks or moves in the direction of the emergency exit (E).

The operation of the emergency exit guidance device 200 according to the present invention configured as described above will be described.

As shown in FIGS. 7 to 9, with the coupling support 130 having the connection port 220 mounted on the side rail 110 of the wire tray 100, the guide module 230 is configured. The locking piece 232A of the case 232 is inserted into the coupling hole 212.

Then, the connection terminal 236 is connected to the connection port 220.

Through this process, the control unit 244 of the control module 240 and the server 300 are electrically connected to transmit and receive data and receive power.

Additionally, the control unit 244 is electrically connected to the detection unit 242 and can receive a detection signal detected by the detection unit 242.

Meanwhile, when a fire occurs in the underground space (S), each detection unit 242 installed in the wiring tray 100 detects smoke, heat, and flame and transmits a detection signal to the control unit 244.

The control unit 244 determines whether the detected signal is valid by performing a process such as comparing the signal detected by the detection unit 242 with previously stored data.

When the control unit 244 determines that the detection signal detected by the detection unit 242 is valid, the control unit 244 first transmits the detection signal to the server 300 and operates the laser beam generator 234.

The laser beam generator 234 radiates a laser onto the floor, ceiling, and/or wall of the underground space (S) and displays a path to the emergency exit (E), that is, a guide beam (L).

In this way, when a fire occurs in the underground space (S), the detection unit 242 of the wire tray 100 installed throughout the underground space (S) can detect it in advance, and the control unit 244 operates the laser beam generator 234. By activating it to irradiate and display the guide beam (L), which is the escape route to the emergency exit (E), evacuees can quickly and easily recognize the escape route to the emergency exit (E) and escape.

Meanwhile, when flooding occurs in the underground space (S), the flooding detection sensor 242D detects this and transmits it to the control unit 244, and the control unit 244 determines the pre-stored standard distance value between the floor and the wire tray 100 and The measured distance value between the floor and the wire tray 100 detected by the flooding detection sensor 242D is compared and calculated, and if the measured distance value is small, flooding is determined.

Next, a flood detection signal is transmitted to the server 300 and the laser beam generator 234 is operated to emit a guide beam (L) for evacuation.

In this way, emergency evacuation situations due to flooding as well as fire in the underground space (S) can be quickly detected and evacuees can be quickly and easily guided to evacuate to the emergency exit, thereby preventing safety accidents in advance.

As described above, since the emergency exit guide device 200 is provided on the wire tray 100, it is easy for evacuees to identify the location of the emergency exit (E) and the escape route to the emergency exit (E) in the event of an emergency such as an earthquake, fire, or flood. I can guide you.

In addition, since the emergency exit guidance device 200 is provided on the wire tray 100, separate wiring construction for electrical connection for power supply and data transmission and reception is unnecessary, making installation and construction of the emergency exit guidance device 200 quick and easy. This can be done and the installation period and cost can be significantly saved.

Although specific embodiments of the present invention have been described and shown above, it is known in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. This is self-evident to those who have it. Accordingly, such modifications or variations should not be understood individually from the technical idea or viewpoint of the present invention, and the modified embodiments should be regarded as falling within the scope of the claims of the present invention.
