Description

refuge device

technical field

The present invention relates to refuge devices.

Background technique

Usually, in the event of a fire, a separation method is generally adopted in which smoke from the fire space is sucked in and air is supplied to the non-fire space to prevent the smoke from the fire space from spreading to the non-fire space.

In addition, the method of temporarily suppressing the spread of smoke by using the smoke control partition wall installed on the ceiling and cutting off the smoke in the fire space by using the shielding plate is assisted by adopting the following method. At this time, the evacuees in the fire space must move to the non-fire space faster than the smoke diffusion speed, so as to protect themselves from the poisonous gas.

However, the evacuation method using the smoke control partition wall is not suitable for all places because there is no smoke control partition wall in wide open spaces such as large waiting rooms or subway halls; The interior is quickly filled with smoke, and the evacuees in the fire space need to move to other spaces at a faster speed, and there is no other means of protection before the evacuees move to other areas.

And, in the event of a toxic gas terror without thermal buoyancy, it is difficult to properly control the toxic gas only by the exhaust vents provided on the ceiling. Therefore, there is a need for an evacuation device that can continuously protect evacuees regardless of the buoyancy of the toxic gas and the fire area.

Here, the detector 10 can generate a control for selectively driving the screen portion 20, the air inflow portion 30, the water spray portion 40, and the emergency lighting 50 described later when a fire occurs or a toxic gas leaks. Signal. The detector 10 is not only arranged on the inner ceiling of the evacuation passage 20a shown in the figure, but also can be arranged in multiple places such as the inner side of the evacuation passage 20a.

As shown in Fig. 2, the screen part 20 includes: a pair of support rods 21, which extend long toward the safety zone on the ceiling of the escape passage 20a; on the rod 21, and can be unrolled; the drive motor 23 is respectively connected with the pair of support rods 21 for winding or unwinding the roller blind 22; and the weight bar 24 is fixed on the pair of roller blinds 22 lower end.

Preferably, one end of the pair of supporting rods 21 is connected to the rotating shaft of the driving motor 23, and is rotatable in two directions, and is formed into a rod shape so as to facilitate winding and unwinding of the roller blind 22 .

The whole or lower end of the roller curtain 22 is made of transparent material, and vertical lines 22a can be formed at a certain interval along the longitudinal direction, so that refugees can freely enter the interior of the escape passage 20a from the outside of the escape passage 20a. In addition, an evacuation guide sign 22b indicating the evacuation direction along the width direction of the roller screen 22 may be provided to guide the evacuee to move easily.
