Description

[Detailed description of the invention] The invention of this application relates to a retractable curtain device for smoke protection.

Conventionally, in the event of an indoor fire, the growth of the fire has been prevented by closing the room where the fire originated, the fire walls around the waxworks, etc.

However, in this case, victims who were trapped at the fire site due to the closure of the firewall had the disadvantage that they were more likely to die of suffocation due to the smoke or toxic combustion gases.

Also, if efforts are made to completely rescue victims from the fire scene, the time to close the firewall will be missed, and the original function of the firewall will not be able to spread the fire or cause smoke to reach other areas other than the site where the fire occurred. The disadvantage was that it was impossible to prevent this.

Particularly in the event of a fire associated with an earthquake, water supply lines or conductive lines are likely to be torn, resulting in a loss of water supply or power transmission, which may result in dependence on water supply as a water source or various equipment driven by motors. There was a problem in that it was extremely dangerous to have one.

In particular, fire protection water curtains equipped with conventional water pipes,
Regardless of the reason, they had the disadvantage that they would lose their functionality completely if water was cut off.

The invention of this application aims to eliminate the above-mentioned drawbacks.

Next, the specific structure of the container for achieving the above purpose will be explained with reference to the drawings. It consists of a liquid-absorbing telescopic curtain and a container for storing the telescopic curtain, and the upper end of the liquid-absorbing telescopic curtain is placed at an appropriate position on the ceiling or in the vicinity thereof. Attach the lower end of the liquid-absorbent telescopic curtain to
A part of the retractable curtain storage container is attached to an appropriate position on the ceiling, and the retractable curtain storage container is attached to the ceiling so that it can be hung down from the ceiling to the floor below. The liquid-absorbing telescopic curtain is made to be rotatable around the center and the container can be tilted, and the liquid-absorbing telescopic curtain is accommodated in the telescopic curtain storage container, and water, water glass, liquid fire extinguishing agent, etc. is placed in the container. A smoke and fire prevention device which stores a liquid together with the liquid-absorbing telescopic curtain, and when the telescopic curtain storage container is tilted, liquid such as water, water glass, or liquid extinguishing agent in the container is supplied to the telescopic curtain. A telescoping curtain device,
A water-absorbent or hygroscopic smoke-proofing retractable curtain 1 is housed in a container 8, and the curtain is made to have a width equal to or larger than the gap between the walls 2 of the room or between the walls 2 under the wax. , the upper part of the curtain is installed so as to be in contact with the ceiling 3, and the lower part of the curtain has a length close to the floor surface or has an area of such a length that it comes into contact with the floor surface 4, and is not in contact with the ceiling 3 in normal times. Using the top of the curtain as the origin, bend it in a zigzag pattern and fold it to detect the smoke detector
, or in response to a signal from a heat detector, fire alarm, etc., the curtain 1 is hung straight down from the ceiling;
Alternatively, a string 6 hanging from the ceiling is lowered and the curtain 1 is made to hang down by the pulling force of the string, and the curtain is constantly sucked with liquid such as water 7, water glass, or extinguishing agent. This is a retractable curtain device for fireworks.

Further, a hollow box-shaped container 8' with holes through which water can enter and exit is attached to appropriate locations on the curtain 1, and when the curtain 1 is in a hanging state, a hollow box-shaped container 8' is placed inside the curtain 1. As the stored water continues to come out of the hole, the curtain 1
can be wetted continuously as long as there is water in the hollow box-shaped container 8'.

Furthermore, by attaching this hollow box-shaped container 8' to an appropriate location on the curtain 1, it is possible to create a structure in which the curtain 1 can be evenly wetted.

To describe the effects of the above configuration, under normal conditions, the water-absorbing expandable curtain for smoke prevention fires is contracted and placed inside a container, and the container is kept in contact with the ceiling, so that there is no problem in using it indoors or under wax. Leave it in a state where it is not present.

When a fire breaks out, the water-absorbing expandable curtain is released from inside the container and hangs down from the ceiling.The water-absorbing expandable curtain absorbs moisture and absorbs the heat of vaporization, reducing the temperature and suppressing the spread of the fire.At the same time, it suppresses the spread of smoke and toxic gas. It has the effect of stopping it with a curtain.

In addition, victims at the scene of a fire can escape to a safe zone by passing through the lower part of the water-absorbing telescopic curtain for smoke and fire prevention in the same way as passing through a mosquito net, and even after that, the water-absorbing telescopic curtain for smoke and fire protection continues to hang down. The shape of it! It also has the effect of being a water-absorbing expandable curtain for smoke and fire protection.
