Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an evacuation guidance apparatus for a rack-type warehouse having a light source section that can be easily identified,

The present invention relates to an evacuation guidance apparatus for a rack-type warehouse having a light source section easily distinguishable, and more particularly, to an evacuation guidance apparatus for a shelter type warehouse, To a shelter type warehouse evacuation guidance apparatus having an easy light source unit.

Generally, along with the development of industries, large buildings that can accommodate a large number of people for residential or business use are increasing, so that the damage caused by a fire or a power outage becomes unimaginable. Accordingly, it is obligatory to install an emergency lighting system in a large building to assist the evacuation in case of a fire.

Especially, along with the development of logistics, large warehouses and warehouse type marts are emerging. The characteristics of these warehouses are to elevate the space utilization by vertically stacking objects through racks. Due to the nature of the building that vertically stacks objects through racks, ceilings are high, and maze-like paths are naturally formed by the racks on which the objects are placed.

However, in the current Fire Prevention Law, the guiding light for evacuation is installed at the entrance or the front of the ceiling. Therefore, in the warehouse having such a rack structure, since the high ceiling and the structure of the rack do not show the evacuation guidance light easily, . In addition, in the case of a rack-type warehouse, the naked eye is naturally hardly distinguished because of the rack in which the object is loaded, and it is excluded from the legal installation of the emergency light which operates during a power failure.

On the other hand, the emergency lighting lamp is designed to inform the direction of evacuation so that evacuees who have to get out of the facility promptly in case of power outage due to fire occur safely and smooth evacuation activities, do. Such an emergency lighting lamp is an emergency evacuation lamp which is built by an emergency power source and is normally turned on by a commercial power supply and is automatically turned on by an emergency power supply by a built-in accumulator when a power failure occurs in an emergency such as a fire. Such an evacuation lamp uses a fluorescent lamp, an incandescent lamp, or an LED.

However, when a fire occurs, the visibility distance that can identify the evacuation guidance light due to smoke is drastically shortened, so that the evacuee can not easily identify the evacuation guidance light. In addition, since the evacuation lamp is located near the stairway entrance or the emergency door rather than the position of the element such as the pillars in the middle, it is located near the stairway or the emergency door There is a problem that it is difficult to recognize easily as an evacuator located between the racks. In the case of a rack-type warehouse in which corridors and labyrinth-shaped passages are generated naturally due to the racks, an evacuation lamp is almost useless, so an emergency evacuation device applicable to the asle between the racks and the racks is required Do.

In addition, in a rack-type warehouse having a resident worker who is familiar with the structure of a building as well as a rack-type warehouse-type warehouse, there is a danger of evacuation due to a panic phenomenon occurring in a fire. Therefore, there is a need for an evacuation device installed at a certain height of the columns of the rack to properly guide evacuation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an evacuation guidance apparatus for a rack-type warehouse having a light source section which is easy to identify according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 (a) is a schematic view showing a state in which an evacuation guidance apparatus for a rack type warehouse having a light source section easy to identify according to a first preferred embodiment of the present invention is installed on a column, and Fig. 1 (b) Is a view schematically showing a state in which an evacuation guidance apparatus for a rack type warehouse having a light source section easy to identify according to a first preferred embodiment of the present invention is deployed on a column.

Referring to FIG. 1, an evacuation guidance apparatus 100 for a rack-type warehouse having an easy-to-identify light source unit according to a first preferred embodiment of the present invention includes a main body 110, a rotation unit 120, 2), and a control unit 190 (see FIG. 2). The first and second fire detectors 130 and 132 (see FIG. 2) and the control unit 190 (see FIG.

The main body 110 is installed on a column of a building, and the building is composed of, for example, a rack-type warehouse. In the case of a rack-type warehouse, objects are loaded, and in the case of a conventional emergency light installed at an entrance, it may be covered by objects. Since the present invention is installed in an element such as a column instead of an entrance due to a lateral coupling structure that is coupled to a side of a column, it can not be covered by objects and can easily identify an evacuee in case of a fire, There is an effect to be made.

The main body 110 is formed in a vertically long shape along the longitudinal direction of the column, and the receiving portion 112 is formed concavely at one side not facing the column.

The rotation part 120 is formed in a long shape to be received in the receiving part 112 and is rotatably coupled to the lower side of the receiving part 112 by a hinge pin (not shown) or the like. The control unit 190 controls the fixing unit 140 so that the rotation unit 120 can be rotated by the rotation unit 120. The rotation unit 120 rotates the rotation unit 120, And is rotated downward so as to be perpendicular to the longitudinal direction of the main body 110. Since the rotation unit 120 is configured to be accommodated within the main body 110, it is possible to manufacture the rotation unit 120 with a small size that does not take up a large volume, thereby preventing the operation of the forklift and the pallet running inside the rack- . In addition, since the rotary part 120 is normally housed in the main body 110, it can be manufactured in a small size that does not take up a large volume, so that it is not limited by the installation position, There is an effect that it can be installed easily.

The main body 110 and the rotation part 120 may be formed of a steel material resistant to flames.

The rotation unit 120 is configured so that the first and second evacuation guide units 160 and 162 are wound around the first and second evacuation guide units 160 and 162, respectively. The first evacuation guide unit 160 is made of a flexible material such as cloth and has an image printed on one surface thereof indicating the direction of evacuation in the first direction. The second evacuation guidance unit 162 (shown in FIG. 4) is made of a flexible material such as cloth, and an image is printed on one surface of the evacuation direction in the second direction. The first and second evacuation guiding parts 160 and 162 are normally installed inside the rotary part 120. However, when the fire occurs, the first and second evacuation guiding parts 160 and 162 spread out to the outside of the rotary part 120 to form a large area, The evacuation directions printed on the first and second evacuation guidance sections 160 and 162 can be easily recognized.

The illumination unit 170 is provided along the lower longitudinal direction of the rotation unit 120 when the rotation unit 120 is rotated so as to be perpendicular to the main body 110. For example, Since the first and second evacuation guide portions 160 and 162 are brightly illuminated by the illuminating portion 170 when the fire occurs, the evacuator can easily identify the first and second evacuation guiding portions 160 and 162, It is possible to recognize the direction quickly. Further, the extra sub illumination (not shown) around the illumination unit 170 illuminates the periphery of the dark corridor so that the evacuator can easily recognize the evacuation direction.

FIG. 2 is a block diagram of an evacuation guidance apparatus for a rack-type warehouse having a light source section that can be easily identified according to a first preferred embodiment of the present invention.

Referring to FIG. 2, the fixing unit 140 allows the rotation unit 120 to be normally housed in the main body 110, and guides the rotation unit 120 to rotate by the control unit 190 when a fire occurs. For example, the fixing means 140 may include a spring (not shown) provided in a recess (not shown) formed to be recessed in the inside of the accommodating portion 112 opposed to the rotation portion 120, (Not shown) that receives the elasticity of the spring and presses the rotation part 120, a locking part (not shown) positioned between the rotation part 120 and the pressing part, And a valve member (not shown) having a solenoid valve (not shown) for moving the part up and down. When the control unit 190 transmits a control signal to the solenoid valve, the solenoid valve raises the latching portion to cause the latching portion to be spaced apart from the upper portion of the pressing portion. When the latching portion is separated from the upper portion of the pressing portion, And the pressing portion is configured to press the rotating portion 120 downward by the elasticity of the spring.

The first light source unit 180 is disposed at a lower side of the rotation unit 120 when the rotation unit 120 is rotated by the main body 110 so as to face the paper surface so as to project an arrow image directed to the first direction onto the hologram . A hologram implements an image three-dimensionally using the principle of holography, and generally uses a laser. That is, the first light source unit 180 implements an arrow image directed toward the first direction by projecting the first laser onto the ground, that is, the hologram on the floor.

The second light source unit 182 is provided on the lower side of the rotation unit 120 when the rotation unit 120 is rotated by the main body 110 so as to face the ground surface and projects an arrow image directed to the second direction onto the hologram . That is, the second light source unit 182 projects an image of the second laser beam onto the hologram on the ground to realize an arrow image directed to the second direction.

The first fire detector 130 includes a sensor for detecting a fire generated in the building. Such sensors include, for example, an illuminance sensor for converting the intensity of light by the flame into a voltage, a temperature sensor including a thermistor for measuring the temperature by the flame, or an ionization type smoke sensor for detecting smoke using ions . The second fire sensor 132 detects a fire generated in the building using the detection sensor. Here, the first fire detector 130 is positioned closer to the first light source unit 180 than the second light source unit 182, and detects the first fire detection value. The second fire detector 132 is positioned closer to the second light source unit 182 than the first light source unit 180 and detects a second fire detection value. The first and second fire detection values sensed by the first and second fire detectors are transmitted to the control unit 190 through wireless communication or wire communication.

The control unit 190 controls the operation of the fixing unit 140 in accordance with whether or not the first fire sensor 130 or the second fire sensor 132 detects a fire so that the rotation unit 120 moves in the longitudinal direction of the main body 110 Let it rotate at right angles. The control unit 190 receives the first fire detection value received from the first fire sensor 130 and the second fire detection value received from the second fire sensor 132, The first light source unit 180 or the second light source unit 182 is controlled to operate using the difference between the first fire detection value and the second fire detection value. When the first fire detector 130 and the second fire detector 132 detect a fire, the controller 190 controls the first fire detector 130 and the second fire detector 130 132 and receives the second fire detection value from the first evacuation guide 160 or the second evacuation guide 162 using the difference between the first fire detection value and the second fire detection value, ). The first solenoid valve 150 and the second solenoid valve 152 are engaged with the first evacuation guide 160 and the second evacuation guide 162, respectively, The control unit 190 sends a control signal to the first solenoid valve 150 or the second solenoid valve 152 to control the first solenoid valve 150 to release the first evacuation guide unit 160 Or the second solenoid valve 152 releases the engagement of the second evacuation guide 162. When the first solenoid valve 150 releases the first evacuation guiding portion 160, the first evacuation guiding portion 160 is automatically withdrawn to the lower portion of the rotary portion 120 by gravity, The guide portion 160 is easily spread to the lower portion of the rotation portion 120. When the second solenoid valve 152 releases the engagement of the second evacuation guiding portion 162, the second evacuation guiding portion 162 is automatically withdrawn to the lower side of the rotary portion 120 by gravity, The guide portion 162 is easily spread to the lower portion of the rotation portion 120.

Hereinafter, the operation of the rack-type warehouse evacuation guidance apparatus having the easy-to-identify light source unit according to the first preferred embodiment of the present invention will be described.

FIG. 3 is a schematic view showing a first evacuation guide portion of a rack-type warehouse evacuation guidance apparatus having an easy-to-identify light source unit according to a first preferred embodiment of the present invention, and FIG. 1 is a view schematically showing a state in which a second evacuation guide portion of a rack-type warehouse evacuation guidance apparatus having an easily distinguishable light source section according to the first embodiment is unfolded.

Referring to FIG. 3, when a fire occurs in a building, first, both the first fire sensor 130 and the second fire sensor 132 detect a fire, and the first fire detection value and the second fire detection Value to the control unit 190. The control unit 190 receives the first fire detection value and the second fire detection value, recognizes that a fire is generated in the building, operates the fire alarm (not shown), and then activates the fire alarm As shown in FIG.

Then, the control unit 190 controls the first evacuation guidance unit 160 or the second evacuation guidance unit 162 to be deployed using the difference between the first fire detection value and the second fire detection value . For example, if the first fire detection value is smaller than the second fire detection value, since the first fire detector 130 is more secure than the second fire detector 132, the controller 190 controls the first solenoid valve 132, The first evacuation guiding unit 160 controls the first evacuation guiding unit 160 to release the engagement of the first evacuation guiding unit 160 so that the first evacuation guiding unit 160 is deployed below the rotation unit 120. Accordingly, the first evacuation guide unit 160 informs the direction of the first fire detector 130, that is, the evacuation direction in the first direction. Thus, the present invention has the effect of promptly guiding the evacuator to the safest escape route.

The control unit 190 controls the first light source unit 180 to operate based on a result that the area around the first fire sensor unit 130 is more secure than the area around the second fire sensor unit 132. The first light source unit 180 projects an image of a first laser beam toward the hologram in a first direction by projecting the first laser beam onto the floor. Since the first laser beam does not spread by smoke but goes straight ahead, And can evacuate more safely.

4, when the second fire detection value is smaller than the first fire detection value, the control unit 190 determines that the second fire detector 132 is more secure than the first fire detector 130, The control unit 190 controls the second solenoid valve 152 to release the engagement of the second evacuation guide unit 162 so that the second evacuation guide unit 162 is deployed below the rotation unit 120. Accordingly, the second evacuation guidance unit 162 informs the direction of evacuation in the direction of the second fire detector 132, that is, the second direction. Thus, the present invention has the effect of promptly guiding the evacuator to the safest evacuation route.

The control unit 190 controls the second light source unit 182 to operate based on a result that the area around the second fire sensor unit 132 is more secure than the surroundings of the first fire sensor unit 130. [ The second light source unit 182 projects an image of a second laser toward the hologram by projecting the second laser onto the ground, and the second laser directly implements the arrow image without spreading by smoke or the like. And can evacuate more safely.
