Description

The invention relates to fire fighting equipment, in particular, to fire extinguishing devices in tanks with petroleum products, in which foam is used as a fire extinguishing agent.

A device for extinguishing a fire in an oil product tank is known, which contains telescopic tubes for supplying a solution, at one end of the inner tube of which a foam generator and means for its extension are fixed.

A disadvantage of the known device is its inconvenience due to its low technology and design complexity, due to the presence of manual actuators, consisting of rockers, levers and flexible joints, for controlling the valve and the brake, which means. on labor intensity and time to bring the device into action.

The purpose of the invention is to improve the usability.

This goal is achieved by the fact that in a fire extinguishing device in an oil product tank containing telescopic tubes for feeding the solution, at one end of the inner tube of which the foam generator and means for its extension are fixed, the latter has a closing flange placed at the end of the inner telescopic tpy6bi a sealed chamber covering the lateral surface and the end of the outer telescopic tube, and holes are made on the lateral surface of the inner telescopic tube at its other end.

The drawing shows the device, a longitudinal section.

The device has telescopic tubes for supplying the solution (external i and internal 2) and means for moving the foam generator 3, consisting of a closing

flange 4, placed on the end of the inner pipe and sealed chamber 5, covering the side surface and the end of the outer pipe. The holes 6 are made at the opposite end of the inner tube. The outer tube 1 and the sealed chamber 5 are fixed to the reservoir 8 by means of brackets 7.

The device works as follows.

The liquid flows under pressure into the fixed pipe 1. Under the action of the hydrostatic pressure of the liquid acting on the flange 4, the movable internal pipe 2 rises upwards. The extended position of the movable pipe 2 corresponds to the working position of the foam generator 3, which is necessary for supplying foam to the combustion chamber. The holes 6 in the extended position of the pipe 2 emerge from the fixed pipe 1 and open the flow of fluid from the pipe I through the annular cavity of the chamber 5 into the movable

pipe 2 and foam generator 3. The foam formed in foam generator 7 is supplied to the hot surface of the oil product in the reservoir. After stopping the supply of an aqueous solution of the foaming agent, the elements of the device occupy the initial position.

The proposed device makes it possible to more effectively extinguish fires by increasing ease of use, reducing labor intensity and shortening the time for putting the device into action.
