Description

I102 The invention relates to means of rescuing people in case of fires to evacuate them from multi-storey buildings. A device for rescuing people in case of fires is known, comprising an evacuation trunk mounted parallel to the wall of the building and a means for braking 1. The disadvantage of the known device. For saving people at. fires are its low performance properties due to the low-tech design, as a result of which a person, depending on the build, can either hang in the trunk or fly through it without delay and be broken. The purpose of the invention is to improve the performance properties. This goal is achieved by the fact that in the device for rescuing people during fires containing an evacuation barrel installed parallel to the building wall and a means for braking, receiving holes are made in the evacuation barrel, and the means for braking consists of elastic chambers located inside the trunk between the receiving holes and an expansion chamber in communication with the cavities of the elastic chambers. Figure 1 shows the device, a longitudinal section; figure 2 - the use of the device by people; in FIG. 3, an embodiment of an expansion chamber; in fig. - section A-A in FIG. -1. The device for rescuing people in case of fires contains an evacuation barrel of square section, made of fireproof material, rigid or elastic. Into the trunk within each floor there are receiving openings 2. To the inside: the inner surface of the barrel walls at distances from each other, approximately equal to the height of the floor, attached hemispherical elastic hermetic chambers 3, interconnected. The hole formed on top of the hemispherical chambers is somewhat less than the thickness of the thinnest person. The chambers 3 are connected to the common pipeline 5, which is connected to the expansion chamber 6, with piston 7, rod 8 and spring (compression pressure 9). In the lower part of the barrel 1 there is elastic material 10, for example, porous rubber, to see the impact. with a free fall of a person from the lower chamber. At the top of 098, the barrel 1 ends with a deflector 11 through which vents are produced. Figure 3 shows another variant of the expansion chamber, which consists of an accordion-shaped chamber 12, ballast 13. A trumpeter is connected to the lower part of the chamber 12 5. Chambers 3, tubes k, piping 5 and expansion chamber b are interconnected and completely sealed from the surrounding atmosphere.The air pressure in the system and chamber - expansion chamber is equal to the atmospheric pressure, i.e. about 1 kg / cm. The camera 3 is in the straightened position. The device operates as follows: To evacuate a person down, the access opening hatch 2 opens, the person enters the trunk, sits on the elastic chamber 3, lowers the legs in the opening between the cameras and slides down. . Due to the fact that the hole formed by the surfaces of the hemispherical chambers is somewhat less than the thickness of the thinnest person, the chambers will be slightly crushed and the excess pressure in them will be due to the weight of the person. This pressure is transmitted through pipe 5 to the expansion chamber 6. From overpressure, the piston 7 moves to the right, compressing the spring 9, wearing the rod 8. After the person has passed the chambers of one floor; (i.e., he has ceased to put pressure on them); compressed Lug 9 returns the piston 7 to its original position. The air from the expansion chamber 6 is displaced by conduit 5 into the sealed chambers 3 and rectifies them. The person falls further onto the following lower chambers 3. The chambers inhibit the free fall of the person and immediately, mincing, pass it further down to the next lower chambers 3. Thus, the person gets to the bottom of the barrel 1, falls onto the elastic material 10 and leaves trunk. find. In another embodiment, the air overpressure from the weight of the humes is transmitted through conduit 5 to the accordion-like chamber 12. Chamber 12 is straightened, lifting the ballast 13. When a person stops pressing on chamber 3, the accordion-shaped chamber is compressed by the action of ballast 13 and pushes air back into the chamber 3, which in this case is distributed.

 OHO does not require any people

Thus, the device allows for preliminary training and it greatly improves the operation of people of any performance properties for cost estimates. can be used in the evacuation trunk of elastic carts.
