Description

(54) RESCUE DEVICE

one

The invention relates to a mining depot and can be used to protect the respiratory organs of the people during sudden gas emissions in the mines.

Apparatuses are known that provide delivery of liquefied conditioned air for breathing to workplaces. The conditioned air is stored in cylinders at a pressure of 1 atm. and during evaporation it increases in volume by a factor of 73O.

The devices are divided into stationary and portable.

The stationary device, having a mass of about 20 kg, provides fresh air per worker during an eight-hour shift.

The portable device is designed to provide several people with fresh air during a shift. Such an apparatus is carried on a trolley with a mechanical or manual drive.

A portable device is necessary for workers who are in constant movement. He wears on the back of the worker. The mass of the device is up to 8 kg. SEQUE action from 2 to 8 h

However, the size and weight of such an apparatus are large, the time of air supply, depending on the volume of air in the baplon, limited, the sector of movement of the worker, depends on the length of the air supply roll, and therefore is also limited. In addition, when using a portable device, it is possible to move in the clearing of the mines with a low power of the developed seams.

Also known is a life-saving apparatus, comprising a case with a normal h ;.j |) test hatch with self-rescuers placed in it and an air breathing system with EGYPA breathing and dosing tips.

However, such an apparatus b1, c:; tro BKf) i.) Read into the self-rescuer pg) and the sudden emergence of an atmosphere unsuitable for breathing.

Claims (2)

D / 1I fast air supply dp d.hzki in case of an accident; the air breathing system r.ix: -:., Of the device under consideration is provided with a release inside the housing with a starting device inserted into the vice housing with seals on and out, and the saddle at the cii inlet .-iC,:; r-; but the membrane has an under-mouth .-. space communicated with taps for breathing, the saddle at the outlet is provided with a valve, and the lid is a spring-loaded box fixedly connected to the cappan, and the taps for breathing are provided with elastic, euscious; diffusers. FIG. 1 shows the intended apparatus; general view; in fig. 2 is a sectional view of the triggering device A-A in FIG. 1} in FIG. 3-section of the outlet for breathing according to BB in FIG. 1. The saasateic device consists of body 1 and cover 2. Insulated self-rescuers are placed in the casing 5. The air supply system has two outlets 4 for breathing with tubes 5 connecting them to the starting device 6. Air from the mine pneumatic network to the starting device enters through the hose 7, which is connected with an air duct 9 with a cap nut 8 A valve 11 is fastened to the lid of the apparatus by means of a spring clip 10, which blocks the opening of the starter. The starting device consists of a housing 12 with a saddle 13 at the inlet and a saddle 14 at the outlet, pressed to the housing with a nut 15. The saddle at the inlet is blocked by a valve consisting of a sealing gasket 16, a disc 17 with a metering orifice and a flexible membrane 18. The breathing device comprises a fitting 19 for connection to the tube 5, a nut and a diffuser consisting of a spring 21 and a lining 22 made of an elastic material. The device works as follows. When the lid 2 is closed, the opening 14 of the seat 14 is blocked by valve 11. The air pressure in chamber B above membrane 18 is equal to the pressure in chamber D under membrane, so that seat 13 is blocked by disc 17c with gasket 16. In case of an accident, an atmosphere is not suitable for breathing , the roof of the apparatus opens, which causes a displacement of the valve 11. At the same time, due to the pressure drop in chamber B, the membrane 18 is raised, releasing the hole of the seat 13. Booiiyx from the pneumatic pneumatic network along the rod 7 and duct 9 enters the chamber T, and from there through pipe 5 - K. diffiff y When the cover is opened, the spring 21 expands. The victim, having come close to the diffuser, gets breathable air, i Then he brings the isolating self-rescuer, which is in the apparatus, to the working position, and then follows the exit to a fresh air flow, In case the exit is difficult, the miner may be located at the diffuser before assistance to it. The presence of devices installed in the rescue niches of each of the ledges of the lava allows miners to take the necessary measures for self-rescue in case of a sudden release of gas and gas for 30-40 seconds. The formula of the invention and the rescue apparatus, including a case with a normally closed lid with self-rescuer and air breather and a breathing outlet system and metering apertures, characterized in that in order to quickly supply air for breathing during an accident, the air supplying system is provided with a trigger device located inside the body, made in the form of a body with inlet and outlet seats, the inlet seat being provided with an elastic membrane, the submembrane space communicated with breathing branches and seat at the outlet provided with a valve, and the cap - a spring clamp is fixedly connected to the valve, wherein the outlets are provided with a breathable elastic elasstichnymi diffusers.
