Description

The present invention relates to the field of fire fighting equipment and can be used as a means of extinguishing forest fires.

A vehicle for extinguishing fires is known (RF patent No. 2438740 C1, IPC: А62С 27/00, А62С 3/02, publ. 01/10/2012 bull. No. 1 - analogue), containing a traction chassis and two autonomous trailed chassis connected in series by coupling devices with water tanks, medium and high pressure pumps, connecting hoses, barrels and equipment for creating a fire barrier and removing obstacles in the form of metal pipes and trees from the route.

The disadvantage of the analogue is the high energy intensity, as well as low maneuverability and mobility of the vehicle, which makes it inappropriate to use it in situations requiring a quick response.

The well-known forest fire pump (Fire fighting equipment. K.N. Stepanov, Ya.S. Povzik, I.V. Rybkin. Reference: M .: ZAO "Special equipment", 2003, 400 pp. Pages - 102, 103 - prototype), containing a vehicle (motorcycle), a motor pump, a suction hose with a filter in the form of a mesh, connecting hoses (sleeves) and fire barrels for supplying water to the fire fighting zone.

The disadvantage of this motor pump is the inability to extinguish forest fires in places where there are no open water sources. Also, with the help of the prototype under consideration, it is impossible to extinguish a ground fire while moving on a vehicle along the line of propagation of fire. In addition, when lowering the suction hose with the net to the bottom of the reservoir along with water, the motor pump draws in silt, sand and bottom sediments, and when the filter is located near the surface of the water, its mesh becomes clogged with leaves, garbage and branches, which generally negatively affects the operation of the equipment and leads to to his premature wear.

An object of the invention is to expand the functionality by providing the ability to extinguish a fire in the absence of open water sources, as well as providing the ability to extinguish bottom fires by moving along the ignition line on a vehicle, and, in addition, reduce the likelihood of bottom sediment entering through the filter and eliminate clogging of the filter element with leaves and debris.

The objective is achieved in that in a mobile fire extinguishing complex containing a vehicle, a motor pump, a suction hose with a filter, connecting hoses and fire barrels, where according to the invention the vehicle in the form of an ATV is connected via a coupling device to a uniaxial trailer on which a water tank is placed, moreover, a hole is made in the upper base of the container, in which a filter made in the form of a hollow metal the cylinder, the free end of which is perforated with holes of the same diameter, and the float is rigidly fixed to the second end of the filter connected to the suction sleeve, in addition, by means of a check valve the motor pump is connected to the pressure pipe, the cavity of which is connected to the hydraulic accumulator and distributor with taps, which are connected via connecting hoses are connected with fire barrels, the pressure pipe is also equipped with a bypass valve, which is connected to an overflow pipe that communicates with the cavity for water, in addition, in the hole made in the upper base of the tank, a rubber ring cleaning the cylindrical surface of the filter is fixed, and an additional front frame is installed on the ATV, which has an articulated axis in the lower part on which lateral fire barrels are connected by means of two rods, forming a four-link mechanism, a sliding screw strut is also pivotally mounted on the axis, the second end of which is connected to the rods, in addition, a lift is installed in the upper part of the frame second spacers, which is pivotally connected to a fixed part of the sliding thrust on the front of the ATV rack mounted, on which a reel with a hose connection, and in its upper part fixed manual fire barrel.

The difference between the proposed fire extinguishing complex and the prototype lies in the fact that it is equipped with a transportable water tank, which allows the complex to be used to extinguish fires in the absence of open water sources, and the presence of side fire barrels makes it possible to extinguish ground fires by moving on a vehicle along the line of fire. Moreover, with the help of a sliding and lifting screw spacer, you can change the position of the side fire barrels, thereby regulating the range of the jet.

Also, the filter through which water is drawn is installed in a container with the possibility of extraction, which allows it to be used for water intake from water bodies. At the same time, water pumped from an open reservoir can be used both for fire extinguishing (in case the burning center is near a reservoir) and for refueling a tank with water.

Since a float is installed in the upper part of the filter, the lower end of the filter, on which the holes for water intake are located, will always be immersed in water, which will prevent clogging of the filter element with leaves and debris floating on the surface of the water. Moreover, the float also does not allow the filter to sink to the bottom, which reduces the likelihood of bottom sediments, silt or sand entering the filter.

Due to the fact that a rubber ring is installed in the hole in the upper base of the container for placing the filter, the cylindrical surface of the filter is cleaned both when it is installed in the container and when it is removed from the container.

In addition, a distributor with cranes allows you to economically consume water due to the possibility of involving one, two or three fire barrels during fire fighting, depending on the situation.

The proposed mobile fire extinguishing complex contains an ATV 1 used as a vehicle, connected by means of a coupling device 2 to a uniaxial trailer 3, on which a water tank 4 is placed. A motor pump 5 and a hydraulic accumulator 6 are installed in the rear part of the ATV 1. A hole is made in the upper base of the tank 4, into which a filter 7 placed inside the cavity of the tank 4 is mounted, made in the form of a hollow metal cylinder, the free end of which is perforated with holes of the same diameter, and at the second end of the filter 7 connected to the suction sleeve 8, the float 9 is rigidly fixed. By means of the check valve 10 (Fig. 2), the pump 5 is connected to the pressure pipe 11, the cavity of which is connected steam with a hydraulic accumulator 6 and a distributor 12 with valves 13, which are connected via connecting hoses 14 to the side fire barrels 15 and to the manual fire barrel 16. The pressure pipe 11 is equipped with a bypass valve 17, which is connected to an overflow pipe 18 that communicates with the cavity of the tank 4. In the hole made in the upper base of the container 4 for the placement of the filter 7, a rubber ring 19 that cleans the cylindrical surface of the filter 7 is fixed.

An additional frontal frame 20 is installed on the ATV 1 (Fig. 3), which has a pivotally mounted axis 21 at the bottom, on which lateral fire trunks 15 are placed, interconnected by two rods 22, forming a four-link mechanism. On the axis 21, a sliding screw strut 23 is also pivotally fixed, the second end of which is connected to the rods 22, and a lifting strut 24 is installed in the upper part of the frame 20 (Fig. 4), which is pivotally connected to the fixed part of the sliding spacer 23.

A rack 25 is mounted on the front of the ATV 1, on which a coil 26 is mounted with one of the connecting hoses 14, and in its upper part, a manual fire barrel 16 is fixed using clamps 27 and 28.

The complex operates according to two schemes.

Extinguishing a forest fire in the event of a significant removal or absence of open water sources in the vicinity of the source of ignition proceeds as follows. ATV 1 filled with water with a capacity of 4 moves to the place of fire. When approaching the combustion zone, the motor pump 5 is started, through the filter 7 along the suction sleeve 8, water is taken from the tank 4. Next, water from the motor pump 5 through the check valve 10 enters the pressure pipe 11 and fills the accumulator cavity 6. When the working pressure in the pressure head is reached in the pipe 11, the bypass valve 17 opens, and the water flows through the overflow pipe 18 into the tank 4. Then, by opening the taps 13 of the distributor 12, pressurized water is supplied through the connecting hoses 14 to the fire stations olam 15 and 16. With the valves 13, depending on the situation when extinguishing can be operated as one, and two lateral shaft 15, together with them can be used and manual shaft 16, which allows to use water sparingly. Also, the latches 27 and 28 allow you to install a manual fire barrel 16 on the rack 25 at various angles to the horizontal and vertical plane, this allows you to extinguish the fire with the barrel 16 and at the same time control the ATV 1.

When extinguishing a ground fire spreading along a road or a clearing, water is supplied to one of the side trunks 15, and the complex moves along the fire propagation line to extinguish it. Also, if necessary, use a manual barrel 16. When extinguishing a fire on both sides of the route of the complex, both side barrels 15 are used.

If the source of fire is intense or localized, then the ATV 1 is stopped and, loosening the latches 27 and 28, the manual fire barrel 16 is removed from the stand 25 and the water stream is manually directed to the burning site.

In the case of the presence of a reservoir in the vicinity of the fire source, the quenching proceeds according to the following scheme. The complex is placed on the shore of the reservoir, after which the filter 7 is removed from the reservoir 4 and immersed in the reservoir as far as possible from the coast, where there is sufficient depth. The motor pump 5 is turned on and water is taken from the reservoir. After loosening the latches 27 and 28, the manual fire barrel 16 is removed from the stand 25, and the connecting hose, which is connected to the manual barrel 16, is unwound from the coil 26. Then the fire is extinguished using the barrel 16. After the work is completed, the filter 7 is installed back into the tank 4 moreover, during its installation, the rubber ring 19 cleans the cylindrical surface of the filter 7.

In the case of filling the tank 4 with water from the reservoir, it is necessary to close the taps 13.

The use of the proposed mobile fire extinguishing complex will allow extinguishing forest fires in conditions of significant removal or absence of open water sources in the area of the fire source, as well as extinguishing ground fires, moving on a vehicle along the fire propagation line, while spending water economically. In addition, the use of the proposed design will reduce the likelihood of ingress of sediment, sludge or sand through the filter, which will increase the service life of the equipment.
