Fire-fighting projection escape device

Abstract

The invention discloses a fire-fighting projection escape device which can supply a clearer and more definite excavation and escape direction instruction to people who want to be excavated and escape in fire, earthquake, terrorist attack or other emergencies in a large-size public place (such as a hospital, a supermarket, a hotel, an underground parking lot and a metro station) and also supply safety insurance to people who want to be excavated and escape. The fire-fighting projection escape device consists of two parts, namely a projection device part and a fire-fighting spraying device. In an emergency, the projection device part projects an image to the ground by some projection technologies; the image forms a large arrow pattern on the ground; an arrow in the pattern points to a safety exit, a quick passageway, an excavation rally point or other emergency excavation directions; and the fire-fighting spraying device sprays a large amount of water around and to the ground so as to realize functions of extinguishing the fire, absorbing the air heat, reducing the surrounding temperature, adsorbing smoke particles and adsorbing and dissolving toxic and harmful gas. The safety insurance is supplied to people who want to escape.

Description

technical field [0001] The present invention relates to projection technology, such as 3LCD technology, DLP technology, LCD technology, LCoS technology, SXRD technology, D-ILA technology, etc., but is not limited to the above six projection technologies, including some other projection technologies that already exist and may be produced in the future. and fire sprinkler technology. Background technique [0002] In different places and places, whether it is small public places or large public places (such as hospitals, supermarkets, hotels, underground parking lots, subway stations, etc.), the most common "emergency exit" signs, or other emergency evacuation guidance Signs are usually installed on the walls of buildings or pasted on the ground. Some are in the form of flat luminous lights, some are in the form of light boxes or other forms. The "emergency exit" sign or other emergency evacuation guide signs in the form of flat luminous light generally have a small area, and...

AI Technical Summary

Problems solved by technology

Even many signs installed on the ground are only circular devices with a diameter of 20cm. If you are a little far away, you cannot see the information such as the evacuation direction indicated on it.

[0005] Regardless of the form, these "emergency exit" signs or other emergency evacuation guidance signs have a common disadvantage of being small in size and cannot effectively attract people's attention.

As a result, when fires, earthquakes, terrorist attacks or other emergencies occur, often due to confusion, panic, etc., emergency exits or other evacuation guidance signs are not easy to be found in a timely and effective manner by people who evacuate and evacuate under the interference of complex situations.
