Description

 The invention relates to fire fighting equipment, and in particular to machines for fighting forest fires, and can be used in hard-to-reach areas.

 A well-known forest fire unit containing a caterpillar vehicle on which a device for feeding extinguishing agent, a control panel and a mounted working tool for removing soil is installed (see RF patent N 1729526, class A 62 C 3/02, 1992).

 A disadvantage of the known forest fire unit is its low efficiency in extinguishing large forest fires.

A fire engine based on a forest tractor or conversion tracked or wheeled vehicles is also known, on the frame of which fire-fighting equipment is mounted - a catapult with a drive, a hopper for soil, equipment mounted on the back to remove a layer of soil and a three-toed cultivator in front of a hydraulic control machine, as well as a cab the driver, the place of the working fighter-operator and the motor - power unit (see RF patent N 2069577, CL A 62 C 3/06, 35/00, 1996)
The disadvantages of the known fire engines are low cross in dense forest, obstruction of water barriers, and low efficiency in extinguishing a fire.

 The problem solved by this invention is to increase the efficiency when extinguishing a fire with increased cross in the forest and cross water barriers.

 The solution to this problem is provided by the fact that the forest fire unit containing the vehicle on which the device for supplying the extinguishing agent is installed, a control panel, attached working equipment for clearing the strip, including a plow for feeding soil into the catapult, is additionally equipped with cutting bodies for cutting trees and cutting shrubs approach with the ability to change the angle of attack, composite pontoons mounted on the sides of the unit, made with the possibility of folding along ag regatta, a plow made controlled relative to the blade installed behind the unit body, as well as a fire monitor for supplying extinguishing fluid to the combustion zone, as well as the fact that the pontoons serve as containers for water and extinguishing fluid.

 In FIG. 1 shows a general view of a forest fire unit, an assembly view (cutting knives in front and a blade in the back are not shown); in FIG. 2 - general view, top view; in FIG. 3 is a general view, a front view (cutting knives and a cultivator in front of the unit are not shown).

 Fire-fighting unit 1 consists of a base vehicle of a forest or conversion tracked or wheeled vehicle (Fig. 1), on the frame of which fire-fighting equipment is mounted. A fire monitor 3 is installed on the main cabin 2 to supply extinguishing fluid to the combustion zone. The gun monitor 3 is controlled from the remote control by a fighter operator from the cockpit 2.

 Behind the main cabin 2 there is an additional cabin 4 for the fire brigade fighters. The engine 5 (Fig. 2) is located on the side of the main cabin 2 in the middle of the base machine 1. The pontoons 6 are made integral. In the transport position, the pontoons 6 are stacked on both sides of the machine on top of each other. Using hydraulic cylinders, pontoons 6 are extended on both sides of the machine from transport position I (Fig. 3), to working position II (position shown by a dashed line), and then laid out along the unit in such a way that the forest fire unit acquires buoyancy to overcome water barriers on the way movement to the fire.

 Between the pontoons there is a tank 7 for damping additives added to the water, as well as a platform 8 (Fig. 2) for placing additional portable equipment: motor pumps, hoses, hoses, shovels, etc.

 Behind the forest fire unit 1 is a catapult 9 with a hopper 10 and a feeder 11 for feeding soil. The feeder 11 is a scraper conveyor with blowers 12.

 The catapult 9 (Fig. 1) consists of rollers made of rubber or tires of vehicles, while the upper rollers have a smaller diameter and are spring-loaded relative to the lower rollers. The upper roller has the ability to move relative to the lower roller, which allows you to change the firing sector vertically. The catapult 9 can rotate about a vertical axis and thereby changes the horizontal firing sector.

 To mineralize the fire strip behind the forest fire unit 1 mounted dump 13 (Fig. 2). The blade 13 includes a plow 14 for feeding soil into the zone of the heaters 12 of the catapult feeder 11. The plow 14 is movable by means of hydraulic cylinders relative to the blade 13. The catapult 9 is controlled from an additional cabin 4.

 Ahead the forest fire truck is equipped with cutting bodies in the form of knives 15 (see Fig. 2), forming a wedge, and a ripper 16.

 In front and side of cabs 2 and 4 of unit 1, a fence 17 is installed to protect fallen trees from falling on it.

 Forest fire unit operates as follows.

 The head of the crew of the forest fire unit is tasked with a route of movement. At the same time, the need to overcome the forests, their localization from a moving, especially fast, horse fire, which is especially difficult to extinguish (to date, does not extinguish such fires), as well as crossing over water barriers and the place of water collection, is determined. If it is necessary to fill the water after passing through the water barrier, the driver sets the pontoons 6 in transport position I and, using motor pumps, fill the pontoons 6 with water.

 A fully equipped unit moves to the fire and the driver directs it along the front of the fire or to its source. Simultaneously with this movement, the fighter operator switches on the fire monitor 3, ripper 16, plow 14, feeder 11 with heaters 12 and catapult 9. If necessary, pontoons 6 are installed on both sides of the unit. The soil, loosened by the cultivator 16, freed from large lump roots, the upper organic layer by the blade 13 and cut off with a plow 14, is guided by a shield to the feeder 11, and then to the catapult 9 storage bin. The upper and lower catapult rollers 9, rotating at high speed, throw out the soil into the combustion zone. At the same time, directing the fire extinguishing liquid from the gun barrel 3, formed by adding to the water from the pontoons 6, the extinguishing additives from the tank 7, the fighter operator creates a flight of the fire extinguishing liquid together with the flight of the soil into the combustion zone, achieving the greatest fire extinguishing effect. If necessary, you can draw a new portion of water from a nearby reservoir, and so on, until the fire is extinguished.

 To extinguish small foci of ignition not in the main area of the fire, you can use hand-held portable motor-pumps, hoses, shovels, etc.

 At the end of the fire extinguishing, all the fire-fighting equipment of the forest fire-fighting unit is stopped, put in the transport position and moved to the place of deployment.

 The fire-fighting unit is not tied to a water source, it works autonomously, having a sufficient number of fighters, fire-fighting equipment and water, effectively using local soil moistened with fire extinguishing fluid from a fire monitor for extinguishing.

 The fire-fighting unit can be successfully used if necessary in forestry, construction and military affairs.
