Abstract

The fire-extinguishing equipment has accessories (1) with a separate drive shaft of a petrol engine, at which two wheels (7, 8) are attached. An elbow joint and an intake area (9) is provided having an output (9a). In addition, mobile steel tube joints (11, 12) are attached to allow the equipment to be steered. Ash or earth is sucked in via pipe (11) and discharged for suffocating a fire. The mass i.e. of fire, may also be subjected to water where steam is developed with high pressure, which can be used for fire fighting.

Description

in this connection it is a near fire fighting device. It is protected by a protective shield Fire up and steer independently steerable steel pipe over the fire. The paddle wheels be over the PTO shaft is driven by an engine (eg gasoline). The Flame ash and the like be over the intake pipe and over the manifold sucked into the paddle wheel. This mass is mixed with a little water (dosed) enriched. By the heat The mixture expands and is at high pressure over the elbow in the steerable output pipe and finally passed to the fire. It gets through it no more oxygen to the fire, and through This approach stifles the fire (with very little water).

The Device becomes worn with two shoulder straps, and two steering arms control the two tubes. At this Steering arms are the dosing handles for water and engine speed.

The other paddle wheel sucks over an opening on the protective tube of the drive shaft fresh air, distributed and thereby cools inside the protective shield. This extends down to calf height, after up to shoulder height. The overflowing fresh air takes over the protective function for the feet and the Head of the person. Furthermore you have a better view for the work and has constantly fresh oxygen under certain circumstances can a separate hose (over several meters in length) for the Fresh air supply to be connected.

Also the exhaust gases are over the intake pipe led to the fire.

at If necessary, even without water supply the steppe fire can Delete the fire. The intake pipe sucks mainly flame (carbon dioxide), Ash, earth, etc. to the manifold. The solids are due to the centrifugal force in a secondary pipe before the paddle wheel to the output part of the starting steel tube without Water directed to the fire. The diversion of solids should the damage prevent the paddle wheel.

At the Input of the intake pipe is a double grid attached. The front Lattice is with a joint-Gleitschuh and with obliquely inward movable pins. Will the steel pipe be slightly off the ground raised, the diagonally stripes inwardly directed pens from the coarse dirt down, and the grid is clean again. Is the water consumed, can with the water pump driven by the engine and a hose new water to be pumped into the tank.

The fire extinguisher consists of a motor ( 1 ), Tank space for gasoline ( 1a ) and water ( 6 ) on the one hand. On the other side from the shield ( 21 ), with 2 mounting brackets ( 26 ) (with which the extinguisher 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 over an opening ( 3a ) on the protective tube ( 3 ) Fresh air to the inside of the shield ( 21 ). This is distributed laterally downwards ( 23 ) and up (22). The protective shield ( 21 ) reaches down to the calf, up to shoulder height. The overflowing fresh air protects the feet and the head of the person. The second paddle wheel ( 8th ) sucks over the independently steerable steel pipe ( 11 ). The front part consists of two independently steerable steel tubes ( 11 / 12 ); with sliding joint ( 10 ) Mistake. This slip joint ( 10 ) is at the manifolds ( 9 / 9a ) appropriate. A double grid ( 14 / 15 ) on the intake pipe ( 11 ) prevents coarse dirt from entering the intake manifold ( 11 ), wherein the outer grid ( 15 ) with a Gleitfuß- ( 17 ) Joint ( 17a ) and inwardly directed pens ( 16 ) when lifting the intake pipe ( 11 ) the inlet grille ( 14 ) cleans (see 2 ). The paddle wheel ( 8th ) sucks over the suction steel pipe ( 11 ) and the intake part of the manifold ( 9 ) Flame, ashes, etc. At the inlet (inlet) of the paddle wheel housing ( 20 ) is passed over a steel tube ( 26 ) some water with a dosing handle on the steering arm ( 25 ) can be controlled into the paddle wheel ( 8th ). Due to the high temperature of the sucked mass, the water becomes steam. It creates an overpressure, and the mixture is at high pressure over the intake of the manifold ( 9a ) and the output tube ( 12 ) thrown to the source of the fire. Coarse dirt ( 19 ) such as rock, etc. is due to the centrifugal force of the solid mass to a byway on the manifold ( 19a ) to the output part of the manifold ( 9a ). This allows the paddle wheel ( 8th ) are not damaged. In addition, the exhaust gases ( 4 ) from the engine ( 1 ) over the manifold ( 9a ) and the output tube ( 12 ) to the fire. An automatically controlled valve ( 4a ) controls the exhaust gas flow. With a switchable tensioning belt V-belt ( 5a ) you can with the water pump ( 5 ), which is driven by the engine, the water tank ( 6 ) to refill.

Claims (9)

As a result, the fire extinguisher consists of a gasoline engine incl. Accessories 1 with a separate drive shaft, on the two paddle wheels 7 + 8th are attached. Characterized gekkizeichnet that the manifold from a suction 9 and an output part 9a consists. At each of these are manually controlled, movable (joints) steel pipes 11 + 12 appropriate. Characterized gekkzeichnet that the resulting solids in a fire (ash / soil / fire) on a pipe 11 with a paddle wheel 8th sucked and ejected to suffocate the fire again. If necessary, this mass can be supplied with water, resulting in steam and the result of a high pressure, which can be used for fire fighting. This marked, at the bottom of the intake manifold 11 There is a double grid, consisting of a fixed inlet grille 14 , with a movable cleaning grid 15 , The (pre-grid) cleaning grid 15 consists of a sliding shoe 17 and obliquely inwardly directed pins 16 and a joint 17a , If you lift the intake pipe 11 Slightly push the slanted inward cleaning pins 16 the coarse dirt down and the inlet grille 14 is clean again (s. 2 Page 2). This marked, the drive shaft 2 in the protective tube 3 is stored, is over the V-belt 5c driven. Marked thereby, so that the person is protected from the heat, is a protective shield 21 intended. To cool this, the inner paddle wheel sucks 7 via an opening on the protective tube 3 Fresh air on. The air is distributed halfway up and down. The protective shield is enough for the person to walk well 21 down to calf height only. And so that you can still see well, it is only enough to shoulder height. With the overflowing air up and down, the person is sufficiently protected from heat. At the inlet opening 3a on the protective tube 3 a hose can also be connected. This fresh air can be sucked from far away. Thereby marked, with an emptied water tank 6 can the water pump 5 be turned on and over a hose 5b be refueled. The water can be taken from a variety of supplies. The water requirement (generally very low), which is needed to extinguish the fire, can be achieved with a dosing lever on the steering arm 24 to be controlled. The appropriate amount of water is in the manifold intake 9 directed and ejected. This marked the exhaust gases from the petrol engine 1 be in the manifold exit part 9a guided. A pressure regulator controls the inlet. Thereby gekkzeichnet, in a one-man use, the device with two carrying straps 26 be worn on the shoulders. Otherwise, the fire extinguisher can be attached to all common means of transport.
