RU170374U1 - SECTIONAL EVACUATION DEVICE - Google Patents

Abstract

The utility model relates to rescue equipment used to evacuate one or a group of people from the upper floors of buildings (structures). The essence of the utility model is that for the evacuation of people from the upper floors of buildings (structures), a set of sections with a shape close to a funnel with a turned outlet is used as a rescue device, the number of which increases (hooks up) depending on the height of the work. The device allows for the evacuation of people with an average speed of 1.5-2 m / s vertically. In addition, the design is designed for the simultaneous evacuation of up to 5 people in the device, observing the minimum safe distance between them. The technical result is the simplicity of the device, high throughput, as well as providing the ability to use crane technology for evacuation, which frees up special ladders and articulated lifts for point evacuation from other floors of buildings. 3 s.p. f-ly, 9 ill.

Description

The utility model relates to labor protection and special equipment used in extreme situations to evacuate people from the upper floors of buildings (structures) in settlements where there is no special evacuation equipment:

The well-known "System for the evacuation of people from high-rise buildings" (see RF patent No. 2243013, A62B 1/20 publ. December 27, 2004), in which a tensioned inclined tubular sleeve is proposed, the evacuation of which is carried out by sliding down. In this design, a tension cable is used as the sole holding means of the sleeve.

The disadvantages of this system are:

- the need for pre-installation of tubular sleeve elements on each floor of the building, where in case of emergency it is necessary to carry out evacuation work;

- it is required to train the building staff for the correct installation of the tubular sleeve, to spend time on its installation;

- a small "throughput" of the system, and as a result, a longer evacuation time.

The design of the EUROACE S-1 vertical lifeguard is also known (project report No. 5126, “Improving the Methods of Analysis and Risk Management in a Higher Professional Education Institution,” of the Analytical Departmental Targeted Program “Developing the Scientific Potential of Higher Education (2009-2011), Akatiev V. A.), consisting of a cylindrical trough, an entrance frame and an exit capsule, which allows you to evacuate one in five minutes of rescued people at a speed of 1 m / s.

The design under consideration, adopted as a prototype, does not allow for the evacuation of a large number of people in a short time interval, since the cylindrical sleeve groove is designed to simultaneously contain 1-2 evacuated people and a high evacuation time of five minutes per person. In addition, preliminary preparation and briefing of evacuees on the braking method in the rescue arm for its planned movement is required.

The objective of the utility model is to expand the range of evacuation tools to accelerate the evacuation of people for shorter time intervals from a height by increasing the speed of evacuation of one person and the possibility of being in one evacuation device at the same time up to 5 people.

The problem is solved in that the device for evacuation is made in the form of a set of sections, in a shape close to a funnel with a turned outlet at an angle of 135º, sequentially multidirectionally interconnected depending on the floor on which people need to be evacuated, with a metal hoop at the base of the section, to give shape and rigidity to the structure, and a refractory fabric with the above form is attached to the base, to give elasticity, the base and the outlet are connected by a stretching element (rubber rope or a metal spring), and the diameter of the section receiving device is 1.2 m, the output is 0.6 m, and the height of one section is 1.5 m, based on two sections per floor, while the sections are interconnected in four at the points with nylon ropes with a diameter of 0.8 cm, the ends of which are equipped with fire hooks of the DIN5299D type, while the supporting ropes of the device are designed for a load of at least 350 kg, and the upper section of the device for a more snug fit to the building has a square base with ribs 1.2 m long, where do you the running section ends with a lifeguard with a diameter of 0.6 m and a length of 4 m. Completeness in the assembled state, is based on one floor in two sections, and bringing the device into working condition is carried out using crane-type technology, which allows quick and widespread use of sectional devices for evacuation in emergency and emergency situations, while deploying the device and controlling the layout is carried out by at least 4 people.

FIG. 1 intermediate, starting from the second section, except the first and final, each of which is a shape close to the funnel with the outlet turned at an angle of 135º. At the base of the section is a metal hoop 1, for example, aluminum, to give shape and rigidity to the structure, a dense refractory fabric with the above form 2 is attached to this base, to give elasticity, the base and the outlet are connected by a stretching element 3 (rubber band or metal spring). The diameter of the receiving device is 1.2 m in size and the outlet is 0.6 m. The height of one section is 1.5 m, calculated as two sections per floor, since the average height of one floor of typical buildings is three m.

In FIG. 2 shows a complete assembly, where sections 4 are connected to each other at four points by kapron ropes 5 with a diameter of 0.8 cm ending with standard fire carbines 6, for example DIN5299D carbine, so that the direction of the subsequent funnel is turned in the opposite direction relative to the previous one. Such a connection reduces the speed of a person in them due to the constant change in the trajectory of movement and the occurrence of friction forces on the material of the section. From evacuees are required to group and get into the central part of the upper section.

An evacuated person who gets into the device moves with a constantly changing trajectory with an average speed of 1.5-2 m / s vertically, and the supporting structural elements are made of refractory rope capable of holding a load of at least 350 kg based on 5 evacuated each on average 70 kg .

Depending on the height of the floor at which it is necessary to carry out work on the evacuation of people, the corresponding number of sections is being built up (hooked up). The sections are connected to each other at four points using a refractory rope, at the ends of which carbines are located on both sides for quick building and uncoupling of the segments (Fig. 3).

The upper section of the control system for a more snug fit to the building is proposed to perform with a square base with ribs 1.2 m long (Fig. 4a). The last (closing) section 7 (Fig. 4b) is a standard section with a 4 m long rescue arm attached to the outlet in order to minimize the speed of the evacuated evacuator at the end point and adjust the exit location from the device at a safe distance from the building.

For deployment and installation of the proposed device using a ladder, articulated boom or any industrial truck crane (Fig. 5).

In order to reduce the swinging of the sectional rescue device in the established mode, the ropes 8 are connected to the closing section with carabiners at one end, and the firefighters hold the other end in a taut position (Fig. 6 end section).

The sectional rescue device is located in the box in an assembled compact state and is easily transported by fire or other vehicles. The time to bring into working condition is 5-10 minutes.

This rescue device is supposed to be used to evacuate people from the upper floors of buildings in small towns and villages where there is no special equipment. At the same time, up to 5 people are allowed in the device, however, it is necessary to observe the minimum safe distance between them, which is achieved by delaying the time that evacuees get into the receiving opening of the SEC for at least 2 seconds.

Ease of installation and deployment, high “throughput” allow more efficient evacuation of people from emergency buildings. In addition, this device allows you to use any crane-type equipment, which frees up special ladders and articulated lifts for point evacuation from other floors of buildings.

The novelty of the useful model is the shape of the sections and the order of their connection in the form of a prefabricated sleeve design, which provides a zigzag trajectory of the evacuated extinguishing to a safe speed of their movement in the device.
