Description

The invention relates to the field of fire fighting equipment, in particular, to universal fire engines.

The level of technology

At the moment, the problem of creating a fire engine with an expanded arsenal of technical means, with the possibility of rapid transfer to remote and hard-to-reach areas of wildfires, has not been solved. Existing machines have limited functionality and are not fully capable of solving a set of technical problems that arise when extinguishing natural fires.

Multipurpose self-propelled fire complex (RU 2 396 097).

A device containing a base machine with a platform, equipped with mechanized fire extinguishing equipment and monitoring of the state of the terrain in fire areas placed on this platform, with independent overcoming, if necessary, water barriers, conducting reconnaissance of places and fires, delivery of water, fire extinguishing mixtures to fires , the creation of cut-off lines on the paths of the spread of fires by creating lines of water curtains.

The lack of a fire-fighting complex is limited functionality (it cannot lay a protective strip), the complexity of mobile delivery to a remote burning center.

Multifunctional robotic platform “Pelets 300-MRP” http://www.pelec.ru/mnogofunkcionalnaya-robotizirovannaya-platforma-pelec-300-mrp.

Depending on the modification, the tracked amphibious all-terrain vehicle, equipped with a remote control unit, is designed to extinguish fires, deliver equipment and can operate in manual control mode.

The lack of a platform - limited functionality (can not lay a protective strip).

MRK-RP is a mobile robotic complex for reconnaissance and fire fighting (http://niism.bmstu.ru/otdelyi-nii-sm/sm4-1/79).

It is intended for carrying out visual and instrumental reconnaissance and fire extinguishing operations during the elimination of local foci.

The lack of a complex is limited functional capabilities (it cannot lay a protective strip, it is intended primarily for extinguishing local foci on special objects, it does not possess amphibious properties).

Mobile robotic complex of localization of forest fires (RU 29857 U1).

The remote controlled complex contains a flamethrower and three-section rotary-screw propellers with the possibility of tilting and rotating at different speeds of one relative to the other, with one section providing for the movement of the complex, and the other two provide for the barrier line. The mobile robotic complex locates a forest fire by annealing the forest combustible materials with a flame thrower in the opposite direction to the front of the fire from the barrier line dredged with rotor-screw propellers.

The disadvantage of the utility model is the technical complexity of the implementation of three-section rotary screw propellers, two of which must have three-dimensional positioning with the possibility of tilting and rotating with different speeds of one relative to the other. The description does not indicate information revealing how a utility model can be implemented with the implementation of the purpose and the achievement of a technical result, while these two sections are actually not movers, but cutters. The disadvantage is also limited functionality, which consists only in the localization of the fire (can not extinguish the fire, there is no manual control).

Mobile robotic complex is taken as an analogue (prototype) of the proposed utility model.

Disclosure of the utility model.

The task of the utility model is to expand the arsenal of technical means of combating grassroots fires in predominantly remote and inaccessible areas, allowing to increase the efficiency and safety of firefighters.

The technical result is the use of a multifunctional fire engine with an expanded arsenal of technical means to combat ground fires and increase the safety of firefighters by remotely controlling the machine.

This technical result is achieved by the fact that the proposed universal remotely controlled machine, assembled for a specific type of work performed during fire fighting. Depending on the type of component, the universal machine performs the functions of:

- vehicles for the delivery of fire extinguishing equipment and firefighters to the fire chamber,

- cars for laying of protective strips,

- machines for cutting trees and bushes,

- Machines for supplying water from the source of water supply to the hearth of burning and extinguishing a fire.

All machines have a common, identical part — the base machine; and the individual component for each machine is a specific work unit.

FIG. 1 shows a base machine; in fig. 2 - view along arrow A;

in fig. 3 - vehicle for delivery of fire extinguishing equipment and firefighters to the fire chamber; in fig. 4 - sleighs;

in fig. 5 - machine for laying protective strips; in fig. 6 - view along arrow B;

in fig. 7 - machine for sawing trees and shrubs;

in fig. 8 - a machine for supplying water from the water supply source to the fire source and extinguishing the fire.

Basic machine contains: frame; 2 auger supporting and running elements 1 (Fig. 2); engine with power supply system 2 (Fig. 1); the control unit of the engine and the working apparatus 3 (Fig. 1), the remote control system and telemetry, the secondary power supply unit 4 (Fig. 1); navigation system and positioning 5 (Fig. 1); duplicate manual control system 6 (Fig. 1); a place to accommodate at least one machine operator 7 (Fig. 1). Screw elements are cylinders with a solid screw edge. The movement of the machine is carried out by rotating rotor-screw elements, acting as propulsion. Screw elements have stationary, removable or folding cutters. The machine is controlled by the control unit through the remote control system through a remote control or manually by the operator. The navigation and positioning system is used when working offline.

The machine for the delivery of fire extinguishing equipment and firefighters to the fire chamber contains attachment points for fire extinguishing means 8 and locations of members of the fire brigade 9 (Fig. 3) installed on the base machine. Also, trailed sled trailers (Fig. 4) are additionally used as the location for the placement of fire extinguishing agents.

The machine for laying protective strips has screw elements with stationary fixed, removable or folding mills mounted along the axial length of the screws along the axes of the cylinders 10 (Fig. 5). Thus, unlike the prototype, the screws simultaneously perform the function of thrusters and tools for laying of barrier strips. In addition, the cutters can be solid or fragmentary. To improve the quality of the protective strip, the machine has a primer or plow 11 (Fig. 6). To increase amphibious reliability, screw elements are filled with foam material. Screw support-running elements with cutters can be part of the base machine.

The machine for cutting trees and shrubs contains a circular or chainsaw 12 (Fig. 7) mounted on the base machine. In addition, the machine has a device for skidding woody vegetation with fibers, in a semi-submerged or semi-suspended state 13 (Fig. 7).

The machine for supplying water from the water supply source to the fire center and extinguishing the fire contains a water pump 14 (Fig. 8), a fire monitor 15 (Fig. 8), a set of fire hoses and a water tank 16 (Fig. 8) installed on the base machine . In addition, a blower-sprayer 17 (FIG. 8) can be mounted on the extinguishing machine.

All machines are equipped with a telemetry system for visual monitoring and control of machines when working with a remote control in places dangerous to humans.

Implementation of a universal radio-controlled machine to fight ground fires

Radio-controlled multifunctional fire engines work as follows.

All cars to remote work sites are delivered by aviation and dropped by parachute along with a fire assault force. If possible, cars are delivered by road. The fire brigade can include the whole range of machines and several units, or it can consist of selective machines depending on the assigned tasks.

A car for the delivery of fire extinguishing equipment and firefighters to the fire chamber delivers fire extinguishing equipment and firefighters to the work site through difficult-to-passable places and reservoirs where the standard fire fighting equipment is not able to pass.

The machine for laying protective strips with cutters mounted on auger thrusters cuts off and folds the soil in different directions along the direction of travel. The primer cuts and discards the soil layer between the augers, so the machine creates a protective mineralized strip that prevents the spread of bottom fire. Protective strip can be created by radio control or by manual control.

The machine for cutting trees and shrubs cuts wood vegetation with a circular or chain saw. After the skidding mechanism moves the trees with shrubs from the fire hazard zone to a safe distance. The machine is controlled by radio control or directly by the operator.

The machine for supplying water from the water supply source to the combustion chamber can operate in three modes. In the first mode, the machine enters the reservoir, pumps water into the tank and delivers it to the work site. In the second mode, the machine from the reservoir pumps water through the fire hoses to the work site. In the third mode, the machine extinguishes the fire by spraying water from the tank or using a blower to knock the flame out with a powerful stream of air while spraying water.

Machines can be manufactured using conventional factory equipment and well-known construction materials. As part of the components of some units and machines can be used commercially available products (for example: motor motors, chainsaws, motor pumps, flamethrowers, blower sprayers, radio control equipment).
