Description

Oxygen passage supply device for fire escape escape {OXYGEN CHANNEL FEEDER FOR FIRE ESCAPE ROUTE}

The present invention relates to an oxygen passage supply apparatus for fire escape routes, and more particularly, by supplying an oxygen passage along a corridor or a central staircase of a building at the time of a fire, the user evacuates out of the building while placing a respirator in the oxygen passage. The present invention relates to an oxygen passage supply device for a fire escape escape that guides the user to evacuate in a direction where a fire will not occur when the user evacuates along the center stairway of the building.

In general, modern building styles are complicated and large in size, and interior materials made of various compounds are used. For example, in case of a fire in a building, evacuated people cannot be identified due to dense smoke and toxic gas, and breathing difficulties may occur. Many people are in an accident because they can't find their way out.

In fact, most of the victims of fire accidents are known to suffocate within the first few minutes of the fire due to smoke and toxic gases rather than by direct flames, and these suffocation causes a large catastrophe in fire.

In particular, when a fire occurs in a subway station or a tunnel where facilities are located underground, smoke flows to the ground through entrance passages and ventilation openings, causing severe oxygen shortages and exposing people evacuated along the entrance passages to smoke. The casualties caused by

However, since underground facilities are usually equipped only with a watering device such as a sprinkler for extinguishing a fire in the event of a fire, it is possible to prevent suffocation due to smoke and toxic gases that occur within minutes after the fire occurs. none.

Moreover, the sprinkler is operated by a heat sensor, which is operated only after the room temperature rises above a certain temperature due to a fire, and even if extinguishing a flame, smoke and toxic gas still remain, so that it does not contribute to the prevention of asphyxiation.

Accordingly, in recent years, various types of emergency oxygen supplies have been proposed to prevent victims of asphyxiation in the event of fire.

For example, the Republic of Korea Utility Model Registration No. 0318438 is a portable oxygen respirator that can be conveniently carried in an emergency such as a fire by integrating an oxygen supply control device and a mouth part to breathe bite into the mouth of the small oxygen tank. Utility Model Registration No. 0321101 is equipped with an oxygen supply hose with a flow control unit and an oxygen mask attached to a lamp in a flat box-type oxygen cylinder, which is used to carry it in a normal condition. Emergency small emergency oxygen mask has been proposed to allow for easy evacuation and quick evacuation while receiving oxygen.

However, these conventional emergency oxygen supplies are portable and can only be used because they are expected to carry a fire in normal times, or when a fire crew carries it and enters a fire site and provides it to the evacuee who suffers from breathing difficulties. Not only does it cause a lot of inconvenience, but it is difficult to expect a particularly effective effect on the prevention of asphyxiation that occurs within a few minutes after the fire, because it takes at least a few minutes before the firemen arrive at the site due to the fire.

However, if these oxygen supplies are provided at appropriate intervals in the building's evacuation route, some effects can be expected, but in this case, there is a problem of ensuring the economic burden of having a large quantity of oxygen supplies in the evacuation route. have.

In order to solve the above problems, an emergency oxygen supply system for underground facilities has been developed, and the acid supply system according to the prior art is an emergency oxygen supply system for supplying rescue oxygen to internal evacuators in the event of a fire in an underground facility. An oxygen supply chamber located outside the underground facility, containing an oxygen tank filled with compressed oxygen, connected to the outlet of the oxygen tank, and an oxygen induction pipeline for supplying oxygen in the tank to the evacuation passage of the underground facility in case of fire; In the event of a fire, on / off valves for opening and closing the oxygen tanks, evacuation passages of underground facilities are arranged at regular intervals, and a plurality of oxygen inhalers connected to the oxygen induction pipelines through hoses and at intervals of oxygen induction pipelines. A water supply pump that supplies coolant to the coolant pipes in the event of a fire It includes a program.

Background art of the present invention is disclosed in Republic of Korea Patent Publication No. 10-0593691 (June 26, 2006, the name of the invention: emergency oxygen supply system of underground facilities).

The oxygen supply system according to the prior art has a problem that the user misses the time to evacuate along the passage where the fire does not occur because the user can use only in a certain space.

In addition, the oxygen supply system according to the prior art, because the user does not have a separate technical configuration that allows the user to check the floor or the passage where the fire does not occur, the user choked by harmful gas while looking for an escape route There is a problem that damage can occur.

Therefore, there is a need for improvement.

The present invention provides an oxygen passage along the corridor or the central staircase of the building in the event of a fire so that the user can evacuate to the outside of the building while placing a respirator in the oxygen passage, when the user evacuates along the central staircase of the building It is an object of the present invention to provide an oxygen passage supply device for fire escape routes to guide the evacuation in a direction where a fire will not occur.

The present invention is provided along the passage of the building, the central staircase or emergency staircase, the supply pipe for supplying oxygen; A discharge hole provided in the supply pipe and configured to discharge oxygen supplied along the supply pipe into the passage, the central staircase, or the emergency staircase and form an oxygen passage; A fluid providing part connected to the supply pipe and supplying high pressure oxygen into the supply pipe; A plurality of temperature sensors configured to maintain a predetermined interval in the supply pipe, and detect a temperature of an internal space in which the supply pipe is installed and transmit a temperature signal; And a controller for determining a fire occurrence zone by determining a temperature signal received from the temperature sensor, and transmitting a driving signal to the fluid supply unit to supply oxygen along the supply pipe.

In addition, in the supply pipe of the present invention, a separate supply pipe is installed in each floor of the building, and each of the supply pipes is characterized in that a separate fluid supply unit is installed.

In addition, the fluid providing unit of the present invention, the supply valve is installed in the supply pipe; And an oxygen cylinder installed in the supply pipe and storing compressed oxygen.

In addition, the present invention is characterized in that it further comprises a direction check unit installed in the supply pipe, and indicating the evacuation direction to guide the user in a direction away from the fire generation zone.

In addition, the direction check unit of the present invention is characterized in that it comprises a guide light emitting unit is provided with a plurality of lamps in the supply pipe to irradiate light by selecting the left and right directions according to the drive signal transmitted from the control unit.
