Description

FIELD OF THE INVENTION The invention relates to fire-fighting equipment, in particular to hand-held water barrels.

The purpose of the invention is to increase the compactness of the barrel during storage.

FIG. I shows the device, the general pid; in fig. 2 - nozzles, longitudinal section; in fig. 3 - spacer unit; on ф (г. 4 - compound nozzles.

The device includes a nozzle 1, the switch can be connected directly to the hose.

The device operates as follows: the free end of the outer pipe 8 of the housing is turned outward and rolls into a roll to the nose of the barrel, the sleeve 10 slides over the internal pipe 9 and shifts deep into the barrel, the sleeve 14 is inserted into the pipe 9, the sleeve 14 is attached to the pipe 9, the sleeve 10 is mixed in reverse direction until it stops 12 into the collar 15 of the sleeve 14, the pipe 8 is rolled out, while covering the sleeve 10 and fastening to it. Fire barrel

The tube into the cylindrical housing 2 also simply contains a water supply channel 19, a ring assembly 3, a hermetically connected threaded dead-end channel 20. A nozzle in a device 4 with a shut-off node 5 connected by a quick-release coupling 6 to a hose line 7 and the nozzle 1 with the housing 2 consists of flexible waterproof and j non-expanding outer pipe 8 and a inner cylindro-suspended pipe 9 of a smaller diameter, which is hermetically interconnected at the outlet and the nozzle, inserted into it, and the power unit 3 contains ginmpnuyu cylindrical A 20-inch long spacer forms an extinguishing torch from it, and another sleeve 10, to which by means of a wire through the gap between bushings 10 and 12

KI I 1 is attached externally flexible pipe 8, fills deadlock channel 20, creates there

its internal coaxially cilidric increased hydrailic pressure, which is an arresting sleeve 12, connected to the 10th region, leads to a stressful state of the giddial ribs 13, spaced in js of pipe 8 and 9. As a result, from the last gap between the sleeves, the central sleeve forms a rigid shaft with feed

ku 14 with collet 15, to which is fixed by the canal 19 in the inner pipe 9.

the flexible tube 9 and which, together with the Formed Barrel, performs the same

A tube 9 is inserted with a slide-like function, which is metallic. After the opening of the sleeve 12 is turned off, the collar 15 of the barrel bore water from the channel 20.

When the fire bore is turned on, the water is fed to the inlet of the sleeve 10, where it is divided into two streams, one of which flows through channel 19 and onto the outlet and is supported on the end of sleeve 12, the free end of sleeve 10 is threaded 4 () For the thread in the shut-off node 5, a gasket 16 is installed between the bushing 10 and the shut-off node. The flexible pipes 8 and 9 co-flow and become flat, which significantly reduces the volume of the barrel and allows it to be folded together with the hose and a compact bay without protruding parts. When the barrel sleeve 10 and 12 and ribs 13

put together a whole - FIG. 2, but 35 can counteract the uncontrolled to be individual - FIG. 4. After the collapse of flexible pipes 8 and 9 at the entrance to the channel 20, this ensures guaranteed filling 20, therefore.

In the latter case, their connection at the exit from the nozzle is carried out by an elastic filling ring 17 inserted between the ends of the pipes and stitched (not shown) together with the Q of the barrel.

The proposed fire barrel makes it possible to increase the compactness of fire fighting equipment, to reduce the area occupied by it.

Equipment can be connected directly to the hose.

When the fire bore is turned on, the water line enters the inlet of the sleeve 10, where it is divided into two streams, the sludge of which moves along channel 19 and is exhausted and becomes flat, which significantly reduces the volume of the barrel and allows it to collapse along with the hose compact bay without protruding parts.
