Description

The invention relates to the field of technical means used in fire fighting, and is intended for dismantling roofs, walls, partitions, rafters and other parts of burning buildings in case of fire, as well as for pulling away burning materials during and after a fire.

Known hookers, consisting of a wooden or metal handle more than a meter long, with a tip in the form of a spike connected to a hook bent back [A.G. Ahanchenok. Primary fire extinguishing agents. - M .: 1963, p. 5-7 .; Website: "http://ru.wikipedia.org/wiki].

The hooks are mainly used with a wooden handle and a metal tip. Being on the ship, it is used to get objects out of the water or to moor. It can be used to work with sails. On land, hooks are used to pull boats ashore from the water, or, for example, to pull logs from the river.

Combat hooks are also known, which are weapons with a pole several meters long, combining the functions of a spear and a hook to pull riders off their horses. Such hooks were successfully used by the Novgorodians against the Germans in the Battle of Ice.

The main disadvantage of known hooks is their limited functionality.

The closest in technical essence to the claimed object is a fire all-metal hook, consisting of a steel hook with a spear, planted on a pipe segment, and a grip ring welded to the pipe [Dobrovolsky A.A., Pereslitsky F.F. Fire fighting equipment (Handbook). - Kiev: Technika, 1981, p. 178-179; Website: http: www.supernicolass.narod.ru/Bagor.htm. PROTOTYPE].

The main disadvantage of the known construction of the hook, and other designs, too, is their limited functionality. That is, all known hooks do not carry other functions in themselves except pulling, dragging, or pulling objects with a hook from somewhere.

The technical result from the use of the claimed technical solution is to expand the functionality of the hook.

The technical result is achieved by the fact that in the well-known firebreaker containing a steel hook with a spear planted on a gas pipe segment and a handle made on the other end of the pipe, made in the form of a ring, the spear on the hook contains a longitudinal channel communicating with the pipe cavity and equipped with a spray at the outlet while the pipe on the handle side contains a shut-off body with a fitting for connecting with a flexible hose to an external fire extinguishing device, for example, a backpack fire extinguisher.

The technical result is achieved by the fact that the sprayer is made in the form of a hole with a conical socket at the outlet and is placed in the front of the spear, or made in the form of several holes placed concentrically around the perimeter of its base.

The technical result is also achieved by the fact that the locking body with the fitting, the hook and the handle are placed in the same plane, while the locking body with the fitting are placed at a distance of 45-50 cm from the near edge of the handle.

The first figure (figure 1) shows a general view of the fire hook, and the second figure (figure 2) shows a fragment of a hook with a spray placed concentrically on the side surface of the spear.

The hook consists of a steel hook 1 with a spear 2, mounted on a piece of gas pipe 3, and placed on the other end of the pipe handle 4, made in the form of a ring from a steel bar with a diameter of 20 mm The hook 1 and the handle 4 are welded to a piece of gas pipe 3 (hereinafter the pipe). Pipe 3 can be solid, as shown in Fig. 1, or consisting of separate pieces of pipe connected by connecting sleeves (this version of pipe 3 is not shown in the figures). The length of the pipe 3, depending on the purpose, may be different. The spear 2 on the hook 1 contains a longitudinal channel 5 connected to the cavity of the pipe 3, which is equipped with a spray at the outlet 6. The pipe 3 on the handle 4 side contains a shut-off element (valve) 7 with a fitting 8, for connecting with a flexible hose to an external fire extinguishing device , for example, to a backpack fire extinguisher (a backpack fire extinguisher and a flexible hose are not shown in the figure).

To increase the efficiency of extinguishing fire, the atomizer 6 is made in the form of a single hole with a conical bell at the outlet and is placed in the front of the spear (Fig. 1), or made in the form of several holes placed concentrically around the perimeter of its base (Fig. 2).

To ensure convenience during operation, the handle 4, the locking member 7 with the fitting 8 and the hook 1 are placed in the same plane, while the locking member 7 with the fitting 8 are placed at a distance of 45-50 cm from the proximal edge of the handle 4.

As an external fire extinguishing device, a backpack fire extinguisher with various extinguishing agents, for example water, carbon dioxide and other means, can be used. When parsing the rubble of a burning building, or structure, a firefighter can use hook 1 to pull away burning materials and building elements and simultaneously extinguish the fire at its local points. When extinguishing the fire, the firefighter opens the valve 7 and the flame-retardant liquid from the backpack fire extinguisher through a flexible hose and pipe 3 enters through the channel 5 of the spear 2 into the spray gun 6 and extinguishes the fire.

The technical solution extends the functionality of the fire hook, as it provides the possibility of combining the functions of the hook and fire extinguishing agents at the same time. The indicated capabilities of the hook allows you to quickly and efficiently solve problems when fighting fires in places that are difficult to access with ordinary heavy fire fighting equipment placed on special vehicles.
