Abstract

The fire extinguisher has an engine (1), a tank for petrol (1a) and water (6) on one side and a protective shield (21) on the other side, with two carrying bars (26) for strapping on the shoulders. The drive shaft (2) has a protective pipe (3) forming fresh air supply for the bucket wheel (7) sucking up fresh air to inside the protective shield which extends up to shoulder height so that the fresh air protects the feet and head of the operator. A second bucket wheel (8) sucks in ash etc. through the independently movable steel tube (11). Through the high temperature of the sucked-up mass water turns to steam producing excess pressure and the mixture is spun at high pressure through the intake part of a pipe bend (9a) and outlet tube (12) to the fire place. An automatically controlled valve (4a) controls the exhaust gas flow.

Description

This is a local fire-fighting device. You go with one Protective shield protected against the fire and steers an independently steerable pipe made of steel over the fire. The paddle wheels are connected to the drive shaft with a Motor (e.g. petrol) driven. The flame ash and the like are over the Intake pipe and sucked over the manifold into the paddle wheel. This mass comes with enriched with a little water. The mixture expands due to the heat out and is with high pressure over the manifold into the steerable outlet pipe and last led to the source of the fire. As a result, oxygen will no longer catch fire stove, and by doing so, the fire is suffocated (with very little Water expenditure).

The device is carried with two shoulder brackets and with two steering arms the two pipes are controlled. These are located on these steering arms Dosing handles for water and engine speed.

The other paddle wheel sucks through an opening in the protective tube of the drive shaft Fresh air, distributes and cools the protective shield from the inside. This is enough down to calf height, up to shoulder height. The overflowing Fresh air takes over the protective function for the feet and head of the person. You also have a better view of the work and you always have fresh ones Oxygen. Under certain circumstances, a separate hose (over several meters Length) for the fresh air supply.

The exhaust gases are also directed to the source of the fire via the intake pipe.

In the event of a steppe fire, the fire can also be started without water if necessary Clear. The suction pipe mainly sucks flame (carbon dioxide), ash, Earth etc. to the manifold. The solids are created by the centrifugal force in one Secondary pipe in front of the paddle wheel to the exit part of the exit steel pipe without Water directed to the source of the fire. The redirection of the solids is said to damage prevent the paddle wheel.

Claims (1)

A double grille is attached to the inlet of the intake pipe. The front grille can be moved with an articulated slide shoe and with diagonally inward-pointing pins. If the steel pipe is lifted slightly from the floor, the diagonally inward-pointing pins wipe off the coarse dirt and the grille is clean again. If the water is used up, new water can be pumped into the tank with the water pump, which is driven by the engine, and a hose, characterized by : The fire extinguisher consists of an engine ( 1 ), a tank compartment for petrol ( 1 a) and water ( 6 ) on one side. On the other hand, from the protective shield ( 21 ), which is connected to 2 carrying brackets ( 26 ) (with which the extinguishing device is carried on the shoulders) and the drive shaft ( 2 ) with the protective tube ( 3 ) (fresh air supply for the paddle wheel ( 7 )). The paddle wheel ( 7 ) sucks fresh air through an opening ( 3 a) on the protective tube ( 3 ) to the inside of the protective shield ( 21 ). This is distributed laterally downwards ( 23 ) and upwards ( 22 ). The protective shield ( 21 ) extends down to the calf, up to shoulder height. The overflowing fresh air protects the feet and head of the person. The second paddle wheel ( 8 ) sucks over the independently steerable steel tube ( 11 ). The front part consists of two independently steerable steel tubes ( 11/12 ) with a sliding joint ( 10 ). This slide joint ( 10 ) is attached to the elbows ( 9/9 a). A double grille ( 14/15 ) on the intake pipe ( 11 ) prevents coarse dirt from entering the intake pipe ( 11 ), the outer grille ( 15 ) having a slide foot ( 17 ) joint ( 17 a) and inwardly directed pins ( 16 ) when lifting the intake pipe ( 11 ) cleans the inlet grille ( 14 ) (see Fig. 2). The paddle wheel ( 8 ) sucks in flame, ash, etc. via the intake steel pipe ( 11 ) and the intake part of the elbow ( 9 ). At the entrance (inlet) of the bucket wheel housing ( 20 ), some water, which can be controlled with a metering handle on the steering arm ( 25 ), is passed into the bucket wheel ( 8 ) via a steel tube ( 26 ). The high temperature of the sucked-in mass turns the water into steam. There is an overpressure, and the mixture is thrown at high pressure over the intake part of the manifold ( 9 a) and the outlet pipe ( 12 ) to the source of the fire. Coarse dirt ( 19 ) such as rock etc. is guided by the centrifugal force of the solid mass to a side path on the manifold ( 19 a) to the outlet part of the manifold ( 9 a). This prevents the paddle wheel ( 8 ) from being damaged. In addition, the exhaust gases ( 4 ) from the engine ( 1 ) via the elbow ( 9 a) and the outlet pipe ( 12 ) to the source of the fire. An automatically controlled valve ( 4 a) controls the exhaust gas flow. With a switchable tensioning V-belt ( 5 a) you can refill the water tank ( 6 ) with the water pump ( 5 ), which is driven by the motor.
