Abstract

A projection escape device for fire fighting is mounted in an indoor site, and is especially mounted in a large-size public place (such as a hospital, a supermarket, a hotel, an underground parking lot, or a subway station), and supplies a clearer and more definite excavation and escape direction instruction to a person who is excavated and escapes in fire, an earthquake, a terrorist attack or another emergency, and also provides safety insurance to the person who is excavated and escapes. The projection escape device for fire fighting consists of two parts, namely, a projection apparatus part and a fire-fighting spraying apparatus part. In an emergency, the projection device part projects an image to the ground by using some projection technologies; the image forms a large arrow pattern on the ground; an arrow in a pattern points to a safety exit, a quick passageway, an excavation and rally site or another emergency excavation direction. The fire-fighting spraying apparatus 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, thereby providing safety insurance to a person in escape.

Description

Fire projection escape

Technical field

The present invention relates to projection technologies 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 have been produced and may be generated in the future. And fire sprinkler technology.

Background technique

Different places in different places, whether 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 The logo is usually installed on the wall of the building or pasted on the ground. Some are in the form of flat luminous, some are light box or other forms. The "emergency exit" sign or other emergency evacuation guide sign in the form of flat luminous, the general area is small, the distance can not be seen clearly from the distance, and under normal circumstances, it does not emit light and does not sound, usually it is not easy to cause People's attention. In the event of a fire, earthquake, terrorist attack or other emergency, due to people's confusion, nervousness, or dim caused by power outages, or low visibility of smog, or densely blocked lines of sight, or other uncertainties, It is even more difficult to attract people's attention, even those who are difficult to escape by evacuation, it is difficult to provide accurate and effective clear and clear guidance on evacuation and escape directions for people evacuated in emergency and complex situations.

The "emergency exit" sign or other emergency evacuation guide sign in the form of a light box is to install lighting equipment inside it to make it shine, so as to get people's attention in peacetime, and to be discovered by people in the dark. Although the "emergency exit" sign or other emergency evacuation guide sign in the form of a light box is compared with the form of a flat luminous form, there is a certain amount of attention in terms of attracting attention, especially in emergency and complex situations. Advantages, but their advantages are limited. In the event of unforeseen fires, earthquakes, terrorist attacks or other emergencies, there may still be dim caused by people's panic, nervousness, or power outages, or low visibility of smoke, or densely blocked lines of sight, or Other uncertainties, which are difficult to attract people's attention, and even difficult to be discovered by people who escape and evacuate, are also difficult to provide clear and clear evacuation and escape directions for people evacuated in emergency and complex situations. Guidelines.

Especially in many large supermarkets, due to the complexity of the merchandise placement, the complicated internal roads in the supermarket, the first time entering the supermarket or people who are not familiar with the route, under normal circumstances, even according to the exit signs, or other evacuation guidance The guidelines for the logo are also difficult to find the export accurately and smoothly. Or in museums and large exhibition halls, due to the huge size of the site, the "emergency exit" sign or other emergency evacuation guide signs on the ground or wall, but for the huge site area, can be in any place The visitors of the location found these signs in time, and the ordinary flat luminous form and the logo mark in the form of light boxes were not so timely and effective. Even many of the signs on the ground are only circular devices with a diameter of 20cm. It is impossible to see the evacuation indicated above. Direction and other information.

Either way, these "emergency exit" signs or other emergency evacuation guide signs have the same shortcomings that are not effective enough to draw attention. This leads to the timely and effective discovery of emergency exits or other evacuation escape signs that are not easily disturbed by complex situations in the event of a fire, earthquake, terrorist attack or other emergency, often due to confusion, panic, etc. This requires a new product that, in an emergency and complex situation, can quickly, accurately and effectively provide directions for evacuating evacuated personnel, while at the same time providing the necessary security protection.

Summary of the invention

Fire Projection Escapes are designed to help people evacuate quickly, accurately, and safely in hazardous, emergency, and complex situations.

Fire projection escapes are installed indoors, especially in large public places (such as hospitals, supermarkets, hotels, underground parking lots, subway stations, etc.). As shown in Figure 1, in the event of a fire, earthquake, terrorist attack, or other emergency, the Fire Projection Escaper projects an image onto the ground that forms a large arrow pattern on the ground or other directional pattern. Arrow patterns or other patterns with directional orientation, pointing in the direction of a safe exit, fast track, evacuation rendezvous, or other emergency evacuation directions. Provide clear and clear guidelines for evacuation and escape directions for evacuation and escape. At the same time, a large amount of water is sprayed around to achieve the effects of extinguishing fire, lowering temperature, adsorbing soot particles, and adsorbing and toxic and harmful gases.

detailed description

The fire projection escaper consists of two parts. They are the projection unit section and the fire sprinkler section.

The projection device part uses some projection technologies (such as 3LCD technology DLP technology LCD technology LCoS technology SXRD technology D-ILA technology, etc., but not limited to the above six projection technologies, including some other projection technologies that have been produced and may be generated in the future. ), when an emergency occurs, as shown in Figure 1, an image is projected onto the ground, which forms a large surface on the ground. Arrow pattern, or other pattern with directional orientation. The direction of the arrow in the pattern, or other pattern with directional orientation, pointing in the direction of a safe exit, fast track, evacuation rendezvous, or other emergency evacuation direction. The image can also display the floor, the distance to the security exit, the flat map, or other information content around the arrow pattern or other directional orientation patterns. For example, the pattern information of "F4" is displayed next to the arrow pattern, indicating that it is the fourth floor. Or display the pattern information of "10M" next to the arrow pattern, indicating that the distance from the safety exit is ten meters.

As shown in Figure 2, there are several fire projection escapes in a site that form a system. The arrow pattern projected by each fire projection escape, or other directional directing pattern, is single, or red or yellow or green. All fire-fighting projection escapes installed in a site, each fire-projection escape device is projected at an angle different from the location of the emergency evacuation (such as a safe exit, fast track, evacuation point, etc.), or Other colors with directional directivity are also different.

As shown in Figure 3, the farther away from the emergency evacuation site (such as safety exits, fast lanes, evacuation points, etc.), the fire projection escape, the projected arrow pattern or other directional pattern, the color is red To indicate where to evacuate from an emergency.

Fire-fighting projection escapes that are closer to emergency evacuation locations (such as security exits, expressways, evacuation points, etc.), projected arrow patterns or other directional-directed patterns, the color is yellow to indicate proximity , or have been evacuated to an emergency location.

Close to an emergency evacuation location (such as a safe exit, fast track, evacuation rendezvous, etc.), or a fire projection escape near an emergency evacuation location, a projected arrow pattern or other directional pattern, the color is Green, to indicate that the emergency evacuation location is here, or nearby.

When the fire-fighting projection escape device starts working, the fire sprinkler device partially sprays a large amount of water around the ground and the ground to extinguish the fire, lower the temperature, adsorb the soot particles, and adsorb and dissolve the toxic and harmful gases.

The fire sprinkler system of the fire projection escape device can be divided into three types according to the function. One is to spray only the water column type to the surrounding area and the ground, and the other is to spray only the water mist type to the surrounding area and the ground, and the other is to the surrounding area and the ground. At the same time, the water column is sprayed with water mist. The jet water column type fire projection escape device is more suitable for use in places with frequent fires. The water column sprayed around the ground and the ground is more conducive to extinguishing the fire. The spray mist type fire projection escape device is more suitable for use in crowded, production and processing places. The water spray sprayed around the ground and the ground is more conducive to absorbing air heat, reducing ambient temperature, adsorbing soot particles, and adsorbing dissolved toxic and harmful gases. Escapers provide security. At the same time, the water column water mist type fire projection escape device is more suitable for use. The water mist water column sprayed to the surrounding area and the ground can not only help to extinguish the fire but also absorb the air heat to reduce the surrounding temperature, adsorb the soot particles, and adsorb. Dissolve toxic and harmful gases to provide safer protection for people who escape.

All the fire-fighting projection escapes in a place, the number of them can be very close to each other, for example, one every three meters, or a small distance, such as one every twenty meters. The more the number of fire escape projection escape systems, the closer they are to each other, the more favorable it is for people to accurately move along the direction of their safe escape, and it is more conducive to providing safer protection for those who escape.
