Description

Descending device positioning system for evacuation in case of building fire}

The present invention relates to a system for determining the location of an elevator for human evacuation in the event of a building fire in the field of firefighting technology. In particular, it prevents casualties caused by not being able to locate the elevator due to the problem of poor visibility during a fire, and prevents accidents occurring around the elevator. This is about an improved fire extinguisher location detection system for human evacuation in the event of a building fire, which has been improved to protect against flames during evacuation by always having a fire extinguisher and to use it for initial suppression.

In general, a descender is used to escape using a rope in the event of an emergency such as a fire in a multi-story building such as an apartment or school. It can prevent accidents due to sudden descent during escape by slowing down the descent speed. Let it happen.

The conventional elevator as described above is a rope winding wheel around which a rope is wound and supported on the body, a brake drum provided on the upper body of the rope winding wheel, and the rope winding wheel are meshed together so that the reduction part side is accommodated in the brake drum. It consists of a reduction wheel and a housing that is coupled to the front of the body to seal the components. The reduction unit is configured to form a brake storage section so that a plurality of centrifugal brakes made of arc-shaped bars can be seated.

In the conventional elevator as described above, during the emergency escape process, the rope winding wheel is rotated by the rope, and the reduction wheel meshed with the rope winding wheel rotated by the rope is rotated. In the process of rotating the reduction wheel, the centrifugal force of the reduction unit is rotated. The brake is centrifugally separated from the brake housing and comes into frictional contact with the brake drum.

In this way, when the centrifugal brake and the brake drum come into frictional contact, the rotation of the reduction wheel is limited, which limits the rotation of the rope winding wheel, so the rope's descending speed is limited to a certain speed range.

However, when a fire breaks out, smoke rises so thick that it is often difficult to see what is ahead.

Therefore, even if you pay close attention to the location of the elevator installation, in an urgent situation, evacuees become embarrassed and have a lot of difficulty in finding the location of the elevator. In fact, there are many cases in which they are unable to evacuate in such situations, leading to fatal accidents.

As shown in the examples of Figures 1 and 2, the system for determining the location of an elevator for human evacuation in the event of a building fire according to the present invention includes a management server 100 mounted in the management room of the building, and a specific signal transmitted by the management server 100. A registration terminal (200) equipped with a dedicated app that runs in response to the elevator, and an elevator controller (300) provided in a elevator box (BOX) that stores the elevator installed on each floor of the building and connected to the management server (100) by wire. and a lamp 310 installed on the elevator box (BOX) to turn on and off according to a control signal from the elevator controller 300, and a lamp 310 installed on the elevator box (BOX) to output a specific sound in response to a control signal from the elevator controller 300. ) includes a speaker 320 installed on the

At this time, the registration terminal 200 is a terminal registered to the management server 100, and the smartphone information owned by the building's residents is registered, and the principle is to have all residents register.

In particular, the registration terminal 200 is activated in an emergency and a dedicated app is installed to guide evacuation, and the activation code is designed to be transmitted from the management server 100.

Additionally, the registration terminal 200 is classified and managed according to the floors occupied in the building, and is configured to communicate through a mobile communication network.

In addition, the management server 100 is configured to analyze fire information obtained through fire detectors installed in various places in the building and control the elevator controller 300 at the corresponding location.

In addition, since the elevator controller 300 is connected to the management server 100 by wire, the management server 100 can immediately control the elevator controller 300 corresponding to the location of the fire.

Meanwhile, a descender is installed at the main window of each floor of the building, and the descender is built into an elevator box (BOX).

At this time, a pair of lamps 310 are installed on both sides of the front of the elevator box, and a speaker 320 is provided at a distance from the lamps 310.

Additionally, the elevator controller 300 is driven by commercial power.

The present invention configured in this way is recognized by the management server 100 through various fire detectors when a fire occurs.

Then, the management server 100 recognizes which floor and part of the building the fire occurred, and as soon as the recognition is completed, it lists the occupants of that floor and identifies the listed occupants to the registration terminal 200. Send code.

Accordingly, the registration terminal 200 of the occupant of the corresponding floor is activated and a dedicated app is executed, and the dedicated app displays and guides the elevator at the nearest location to the corresponding floor.

At the same time, the management server 100 transmits a control signal to turn on or flash the lamp 310 of the elevator box close to the origin of the fire on the floor where the fire occurred, and also announces the location through the speaker 320. Control the warning sound to be output.

Therefore, a resident holding the registration terminal 200 can easily and quickly find the elevator box by hearing the lights and sounds, even if it is difficult to see ahead due to smoke, open the elevator box, and use the elevator box. Just take it out and escape.

In this case, it is preferable that the elevator boxes (BOX) are guided sequentially starting from the closest one based on the registration terminal 200.

On the other hand, a fire extinguisher 400 as shown in FIG. 3 is provided next to each fire extinguisher box (BOX), and the fire extinguisher 400 is mounted on a fire extinguisher stand 420.

In this case, the fire extinguisher stand 420 is configured to be driven using commercial power, and a fire extinguisher control unit 410 is built inside the fire extinguisher stand 420, and the fire extinguisher control unit 410 is connected to the fire extinguisher controller 300 and the wired It is connected to , and a limit switch 450 is connected to the fire extinguisher control unit 410.

The limit switch 450 is installed at the bottom center of the seating groove 430 formed on the upper surface of the fire extinguisher stand 420.

And, the lower surface of the fire extinguisher 400 is inserted into the seating groove 430.

In addition, a location confirmation light 440 is installed on the front and upper surfaces of the fire extinguisher stand 420, and the location confirmation light 410 is electrically connected to the fire extinguisher control unit 410 to control on/off.

That is, when the lamp 310 on the elevator box is turned on, the location confirmation lamp 440 is simultaneously controlled to be turned on.

Therefore, it is configured to automatically notify the location of the fire extinguisher 400, and since the light is emitted twice, it becomes easier to find the location of the fire extinguisher.

In addition, if the limit switch 450 does not recognize the fire extinguisher 400, the fire extinguisher control unit 410 automatically switches and notifies the management server 100 that there is no fire extinguisher 400 through the lowering controller 300. , it is controlled so that it can be managed by the administrator.

In addition, the fire extinguisher stand 420 contains 100 parts by weight of FRP (Fiber Reinforced Plastics), 10 parts by weight of polyarylene, and tricalcium phosphate (Fiber Reinforced Plastics) to enhance fire resistance, heat resistance, corrosion resistance, contamination resistance, and durability. 5.5 parts by weight of Tricalcium Phosphate, 8 parts by weight of cyclomethicone, 10 parts by weight of ethylenediaminetetraacetic acid, 40 parts by weight of expanded graphite, 50 parts by weight of a mixture of aluminum hydroxide and magnesium hydroxide in a weight ratio of 1:1, diaryl phthalate It can be molded into a mixed composition by adding 5 parts by weight of (diarylphthalae) and 5 parts by weight of titanium oxide (Titanium Dioxide).

At this time, FRP (Fiber Reinforced Plastics) refers to resin reinforced with fiber and refers to composite materials of fiber and resin.

In this case, the reinforcing fiber is glass fiber, the base resin mixed with glass fiber is unsaturated polyester resin, and the weight ratio of glass fiber to unsaturated polyester resin is 2:8.

In addition, polyaniline strengthens insulation by lowering the ratio of stress and strain of molded products, and enhances durability, heat resistance, and strength characteristics by enhancing the properties of conductive polymers by increasing dispersion power.

In addition, Tricalcium Phosphate prevents contaminants from attaching to the surface and prevents the surface from being stained or contaminated with dust.

In addition, cyclomethicone has the basic function of preventing static electricity, and in addition, it protects the surface of the molded product and strengthens heat resistance.

Additionally, ethylenediaminetetraacetic acid is added to prevent rancidity due to oxidation and strengthen the corrosion resistance of molded products.

In addition, since Expandable Graphite has a layered structure of graphite, when atoms or small molecules are inserted between the layers and heat is applied, they separate like an accordion and the particles expand hundreds of times, making it flame retardant. Demonstrate. In particular, expanded graphite has flame retardancy by forming a scale-like layer that is stable to heat or chemicals due to the expansion of the graphite. In particular, it is environmentally friendly because it contains no halogen components and does not have the problem of heavy metal leaching.

In addition, aluminum hydroxide is an amphoteric hydroxide of aluminum. When in contact with water for a long time, it tends to gel and solidify, which helps improve insulation. Above all, it is an antacid, so it is effective in increasing flame retardancy by blocking oxygen in the event of a fire. Therefore, it is added.

In addition, magnesium hydroxide is a hydrate of magnesium and does not react with water, but since this component also has antacid properties, it is used as an inorganic flame retardant to increase flame retardancy in the present invention.

In addition, diarylphthalates are added to improve adhesion and toughness between components and increase heat resistance, dimensional stability, and chemical resistance, including suppressing cracking.

Titanium Dioxide is a material corresponding to CAS number 13463-67-7 and is added to block ultraviolet rays and prevent surface acidification of the disc, thereby suppressing durability degradation and deterioration of lifespan.

In addition, as shown in FIG. 4, a buffer unit 500 is provided on the bottom of the seating groove 430 of the fire extinguisher stand 420.

Since the buffer unit 500 is randomly thrown or pushed when seating the fire extinguisher 400 in the seating groove 430, the problem of the seating groove 430 being easily broken or damaged due to the self-load of the fire extinguisher 400 is solved. This is to do it.

For example, an installation hole 530 is formed in the lower part of the seating groove 430 of the fire extinguisher stand 420, and a locking protrusion 540 is formed around the upper end of the installation hole 530. (530) is sealed by a stopper (570).

At this time, the bottom plate 510 is inserted into the installation hole 530, and the bottom plate 510 is caught by the locking protrusion 540 to prevent it from moving upward, and the lower surface of the bottom plate 510 A double spring is installed between the stoppers 570.

In this case, the double spring consists of a first spring 550 of the upper and lower side and a second spring 560 of the upper and lower side built inside the first spring 550, and the bottom plate 510 is a heavy object. It is configured to stably elastically cushion (400).

In particular, a through hole 520 is formed through the center of the bottom plate 510, and a limit switch 450 is stably fixed and installed through the through hole 520.

With this configuration, when the fire extinguisher 400 is placed in the seating groove 430, the elastic buffering function of the bottom plate 510 prevents the area around the seating groove 430 from being cracked or damaged.
