Abstract

The invention relates to fire fighting equipment and improves the ease of operation and the efficiency of collecting fluids from shallow ponds. The container with elastic columns is connected to the helicopter by means of a cargo cable, control cable, upper ring element and flexible tons. In a rigid base there is a valve, and on the outer side there is an annular support with water intakes, which are fixed on the base and connected to elastic walls and flexible tami elastic elements. When filling the container, the elastic elements, bending, increase the height of the vessel wall. 5 il.

Description

The invention relates to fire fighting machinery and can be used in extinguishing fires from a helicopter.

The purpose of the invention is to improve the convenience of operation and the efficiency of the intake of fluid from shallow water bodies.

FIG. I shows a fire extinguishing device from a helicopter, a general view during the transportation of a liquid; in fig. 2 - capacity for liquid, in the position of its intake, cut, side view; in fig. 3 - the same, top view; in fig. 4 shows a container for a liquid in a transported position, side view; in fig. 5 - the same, top view.

The device for extinguishing a fire from a helicopter contains a container 1 connected by a cable suspension in the form of a cargo cable 2 with a helicopter 3, and a control cable 4. The container I is made in the form of a thicket with a rigid base 5 in the form of a disk and a wall 6 of elastic material (for example, from rubber). Wall 6 is connected with radial elastic elements in the form of narrow strip plates (arcs) 7 of elastic material (for example, steel) to re-load the wall to the outside. The spring plates 7 are fixed on a rigid base 5, and their free ends are connected by flexible t g (halyard) 8 with an annular element 9, which is fixed coaxially at the lower end of the cable 2. The plates 7 are arranged with uniform angular pitch relative to the vertical axis of the tank 1 and between them, in the peripheral part, the wall 6 has corresponding folds 10 retracting inside the container, which is adapted to change its height by transforming the shape. In the base 5, a central opening 11 is made, in which the valve 12 is installed, H is an example, in the form of a disk to provide access. : ia from the outside into the cavity of the container 1, connected to the control cable 4. The weight of the container 1 exceeds the elasticity of the spring plates 7, therefore, in a suspended state, its shape has a greater height than in the case of fluid intake. Bottom

The vessel I is provided with an annular support 13 with water intake openings for providing good access from the outside to the opening 1 I and for a stable fit to the bottom of the reservoir.

A fire extinguishing device from a helicopter works with / in a tight manner.

When water (liquid) is taken, the tank 1 with the open valve 12 is lowered to the surface of the reservoir, the tension of the cargo cable 2 of the helicopter suspension 3 is virtually eliminated, the flexible rods 8 sag and the weight of the tank itself is compensated (balanced). under the influence of the elasticity of the plates 7, its wall 6 is pressed (deflection). When approaching the fire site by means of the control cable 4, the valve 12 is opened and the water from the tank 1 is poured out through the opening 11 into the fire center.

Claims (1)

Invention Formula A fire extinguishing device from a helicopter containing a container with a wall of elastic material attached to a rigid base 10, connected to the walls of the container with a cable suspension comprising cargo and control cables and flexible bars, an annular element characterized in that increase in convenience) to the outer side and the capacity of the exploitation and efficiency of the intake takes the form of a bowl with a small height. Liquid from shallow reservoirs, the device through the valve 12 enters the central unit with elastic elements, When approaching the fire site by means of the control cable 4, the valve 12 is opened and the water from the tank 1 is poured through the opening 11 into the fire center. Invention Formula The main part of the tank and it sinks into the reservoir, and with the transition of the edge of the tank beyond the boundary of the surface of the reservoir, the process of filling the tank is accelerated. After the container 1 is filled with water, the valve 12 is closed with the help of the control cable 4 and the container for the cable 2 and the tensioned flexible rods 8 are removed from the reservoir, while due to the weight of the container itself and the weight of the collected water 7, the forced-release plate 7 the wall 6 of the container 1 is accordingly transformed with the folding of the folds 10, i.e., the capacity takes the form of a thicket with a greater height much greater than the depth of the reservoir. one end that is radially mounted in a rigid base and connected by free ends with flexible rods, a ring 20 with water intake holes attached below to a rigid base, the elastic wall is made as an annular cup-shaped element and the external part is connected with elastic elements in the center the rigid base has an opening in which a shut-off valve connected to the control cable is installed in the device, the elastic elements being arranged with a uniform angular pitch, and associated with gib3Q kimi connecting rods through the upper annular member. 25 FIG. g Yu FIG. five /// /// /// /// /// /// /// // X /// / 7 / Phage.ch Make up.
