Figure 11 shows a diagram of emergency evacuation from a high-rise building using an evacuation capsule located in a ground-based room.

Common to the proposed devices and methods of evacuation is the presence of an evacuation capsule (EC) equipped with doorways, seats with belts and airbags, windows, a parachute with the possibility of forced withdrawal and a self-braking system.

The evacuation capsule 1, used to evacuate people from high-rise buildings, contains doorways, seats with seat belts and airbags, windows, a parachute and a self-braking system. EC 1 is located on retractable rails 2 in a special room 3 of a high-rise building 4 (Fig. 1), and part of the bottom of EC 1 is the so-called anchor plate 5, lowered on cables 6 after it is separated from the capsule. Anchor plate 5 is used to increase the stability of the capsule 1 during its descent, and also contributes to a faster landing and reduces the likelihood of a collision with other high-rise structures. At least one winch type device can be located in EC 1 for selecting the cables 6 connecting the capsule 1 to the anchor plate 5. The winch for selecting the cables 6 can be located in the anchor plate itself 5. Winches, depending on the drive, can be electric, turbine, with an internal combustion engine, run on compressed air, etc. EC 1 is equipped with its on-board computer that regulates the stages of evacuation.

Consider one of the options for evacuating people. In the event of an emergency, fire or terrorist attack in the building, an alarm is announced and people go to the special room 3. Access to EC 1 is opened, people go into the evacuation capsule and take places. Next, close the doorways of the capsule 1, the guides 2 are pulled out (figure 2). Then release the outward route of the capsule 1, and EC 1 along the guides 2 is displayed outside. As soon as EC 1 is brought out, at the command of the computer capsule 1, the parachute 7 is forcibly (using a mini-rocket), the soft landing stage begins (Fig. 3). The angle of inclination of the floor of the evacuation capsule 1 is automatically adjusted. Then, the anchor plate 5 is separated from the capsule 1 (Fig. 4). When the ground reaches the anchor plate 5, winches are turned on, which select the cables 6, thereby pulling the capsule 1 to the anchor plate 5 (Fig. 5). Before the landing of EC 1, the already known self-braking system is activated (patent RU No. 2171209, dated July 27, 2001, B 64 D 1/14, 17/78, G.Yu. Khalidov). Capsule 1 lands (Fig. 6), doorways open, and people go outside.

To evacuate people from the viewing platforms of television towers, the following evacuation method is provided. The specific location of the viewing platform 8 in the television tower 9 allows you to display the evacuation capsule 10 in the "down" direction, in contrast to the evacuation method in a conventional structure, when the evacuation capsule 1 (Fig. 2) is led in the "side" direction.

The design of the EC 10 is similar to the design of the EC 1 and contains doorways, seats with belts and airbags, windows, a parachute, a self-braking system and a computer that controls the stages of evacuation. EC 10 may have a floor with an adjustable angle. EC 10 is placed on vertical rails 11 in a special room 12 under the viewing platform 8 of the television tower 9. Vertical rails 11 are located at an angle to the conventional vertical axis of the television tower 9 in order to withdraw the capsule 10 to the greatest distance from the television tower 9 and safely withdraw and open the parachute 14. In the lower part of the housing of the viewing platform 8 is a sliding floor 13 (Fig.7). The evacuation capsule 10 can be placed directly on the observation deck 8 itself.

Consider one of the options for evacuating people. In the event of an emergency, fire or terrorist attack, an alarm is issued and people go to a special room 12 of the observation deck 8. Access to the EC 10 is opened, people enter the evacuation capsule and take places. Then, the doorways of the capsule 10 are closed. Then, the capsule 10 is released outward, the sliding floor 13 is moved apart, and the EC 10 along the guides 11 is angled outward. As soon as the EC 10 is brought out and moves away from the tower to the distance required for safe parachute withdrawal, at the command of the capsule 10 computer, the parachute 14 is forcibly (using a mini-rocket) and the soft landing stage begins (Fig. 8). Then, the anchor plate 15 is separated from the capsule. Upon reaching the ground, the anchor plate includes winches that select the cable, thereby pulling the capsule to the anchor plate. Before the landing of EC 10, the already known self-braking system is activated. Capsule 10 lands, doorways open, and people go outside.

For the evacuation of people from high-rise buildings, in which the power was turned off during an accident, the following evacuation method is provided.

The design of the evacuation capsule 16 is similar to the design of EC 1 and contains doorways, seats with belts and airbags, windows, a parachute, a self-braking system and a computer that controls the stages of evacuation. EC 16 may have a floor with an adjustable angle. EC 16 is placed on the rails 17 in a special room 18 of the high-rise building 19. The capsule 16 is connected to the ground room 21 using at least two guide ropes 20. The guide rods 20 pass through the casing of the capsule 16 along its walls (Fig. 9).

Consider one of the options for evacuating people. In the event of an emergency, fire or terrorist attack in the building, an alarm is issued and people go to the special room 18. Access to EC 16 is opened, people go into the evacuation capsule and take places. Next, the doorways of the capsule 16 are closed. Then, the capsule 16 is released to the outside path, and the EC 16 is guided outward along the guides and descends along the guiding cables under the influence of gravity. As soon as the EC 16 is brought out, at the command of the on-board computer of the capsule 16 the parachute 22 is forcibly (using a mini-rocket), the soft landing stage begins (Fig. 9). Before the landing of EC 16, the already known self-braking system is activated. The capsule 16 lands in the ground space 21. Then the doorways of the EC 16 open, and people go outside.

To evacuate people from very high buildings (for example, skyscrapers), the following evacuation method is provided. The specifics of very high structures is that when evacuating from the last floors in the case of using an evacuation capsule mounted on guiding cables directed to the ground premises (as described in the previous method), the ground premises themselves must be at a sufficiently large distance from the structure otherwise the descent angle will be unsafe. And with a high density of construction of high structures, it will be inefficient to locate ground premises, into which after evacuation evacuation capsules should descend, at a great distance. In addition, the guide cables can interfere with other structures or objects of the village. For such cases, we propose the following method of evacuating people.

The design of the evacuation capsule 23 is similar to that of the EC 1 and contains doorways, seats with belts and airbags, windows, a parachute, a self-braking system and a computer that controls the stages of evacuation. EC 23 may have a floor with an adjustable angle. EC 23 is placed on rails 24 in a special room 25 of a high-rise structure 26. The capsule 23 is connected to at least two guiding cables 27 with a special room 28 of a neighboring high-rise structure 29 (Fig. 10). Guide cables 27 may extend through the skin of the capsule 23 along its walls. This is done so that the cables do not interfere with the conclusion of the parachute 30 EC 23. The placement of the so-called “reception point” - a special room 28 in the adjacent high-rise structure 29 can significantly reduce the descent angle of the evacuation capsule 23, which will increase the efficiency of rescuing people from very high structures . A special room 28 can be located both on the roof of the high-rise structure 29, and directly inside the high-rise structure 29.

Consider one of the options for evacuating people. In the event of an emergency, fire or terrorist attack in the building, an alarm is announced and people go to the special room 25 of the high-rise structure 26. Access to the EC 23 is opened, people go into the evacuation capsule 23 and take places. Next, the doorways of the capsule 23 are closed. Then, the capsule 23 is released outwardly, and the EC 23 guides outward along the guides and descends along the guiding cables under the influence of gravity. As soon as the EC 23 is brought out, at the command of the on-board computer of the capsule 23, the parachute 30 is forcibly withdrawn (Fig. 10). This reduces the speed of movement of the capsule 23 towards the special room 28 of the adjacent high-rise structure 29. If necessary, adjust the angle of inclination of the floor of the capsule 23. Immediately before the entrance of the EC 23 to the special room 28 of the adjacent high-rise structure 29, the already known self-braking system is activated in the capsule 23. The capsule 23 "lands" in a special room 28. Next, the doorways of the EC 23 open, and people go outside.

For the evacuation of people from high-rise buildings, in which it is not possible to place a special room with an evacuation capsule, the following evacuation method is provided.

The evacuation capsule 31 is similar to the design of EC 1 and contains doorways, seats with belts and airbags, windows, a parachute, a self-braking system and a computer that regulates the stages of evacuation. Due to the fact that EC 31 during evacuation is at an angle to a horizontal surface, its floor 39 is made with an adjustable angle. This will allow people to conveniently take places, which will increase the efficiency of the process of evacuating people. EC 31 is located in a special ground room 32 located at a certain distance from the high-rise structure 33. The capsule 31 is connected to the high-rise structure 33 using the guide cables 34. The guide cables 34 pass through the casing of the capsule 31 along its walls. On the side of the special ground room, the so-called air sleeve 35 is tightly attached to the evacuation capsule 31, fixed, like the capsule 31, on the guide ropes 34. On the other hand, the air sleeve 35 is tightly attached to the powerful fan 36 located in the special ground room 32 (Fig. .eleven). The air sleeve 35 is an "accordion" of strong material (for example, Kevlar), which is able to withstand heavy loads.

Consider one of the options for evacuating people. In the event of an emergency, fire or terrorist attack in building 33, an alarm is raised and people go to the special room 37 of the high-rise structure 33. At the same time, the fan 36 is turned on in the special ground room 32. Under its action, the air sleeve 35 begins to fill up, stretch out in length and extend the EC 31 up the guide ropes 34. As soon as the EC 31 reaches the high-rise structure 33, the EC 31 is fixed with safety ropes 38 to the high-rise structure 33. The doorways of the EC 31 and the special room 37 open, people enter the evacuation tion capsule 31 and take up space. Next, the doorways are closed. Regulating the release of air from the air hose 35, etching the safety ropes 38, EC 31 on the guide ropes 34, slowly lower them back to the special ground room 32. In case of unforeseen situations when lowering the EC 31, open the parachute and turn on the capsule self-braking system. As soon as the capsule 31 has entered the ground premises 32, the doorways of the EC 31 open and people go outside.
