Description

The invention relates to a device for transporting fire extinguishing agents and fire extinguishing equipment according to the preamble of claim 1.

These are liquid containers of all sizes in round, square or oval shapes, as well as fire extinguisher containers that are used by the fire service as tank fire engines, and external fire water loading containers for helicopter use.

These liquid containers refer to a round, oval or square shape.

In contrast, cuboid containers are used as internationally standardized transport containers for general cargo, preferably in the form of so-called ISO containers.

On the other hand, it is unknown to build liquid containers in the form of an ISO container and use them as transportable liquid containers on the road, rail and on the ship in the size of a 20-foot ISO container. Only liquid containers in round, square or oval shapes are used, whereby even a square tank has unmistakable curves. The reason for the aversion to square containers is mainly their lack of stability, especially when transporting the fire extinguisher container filled with liquid, so that the liquid in the container can

Braking or when lying sideways on winding roads and rough terrain, the air only flows into the bulkhead with low pressure.

It is well known that fires are fought primarily with water and foam extinguishing agents, but the firefighter cannot have enough water on hand at the fire.

The method of firefighting that is still practiced today is that when a house fire breaks out in the city, the water hose is connected to the hydrant and the water jet is directed at the fire using a jet pipe (monitor). Depending on the size of the fire, additional water connections are added.
15

In the villages, fire fighting is carried out in a similar way, except that here the water is sucked in from the nearest pond or cistern using portable pumps and is then pushed through water hoses to the source of the fire at around 8-10 bar. The fire brigades are well equipped for this type of fire fighting.

However, in the event of a disaster, such as an earthquake, forest, moor or steppe fire, the firefighting teams are powerless in the face of this firestorm. The past has shown how many square kilometres of nature have been destroyed by fire, and all because the firefighting teams did not have sufficient fire-fighting equipment at their disposal.

The laid out, kilometer-long water hoses provided the firefighter with a water pressure

WASlOl Page 7

of 3-5 bar. This means that there was only a 20-4Om water jet instead of 70-8Om. However, the fire-fighting crew had to stay 100 m away from the fire at wind force 3, as they had to fight against the wind, to avoid being suffocated by the hot air, and the treetops above them were also burning. Here too there was a risk of being killed by burning falling branches.

The fire-fighting teams had no choice but to only carry out a limited extinguishing operation. This meant that the fire-fighting team had to flee from the blaze if they did not want to be trapped by the fire. In most cases, the equipment fell victim to the fire, and even human lives were lost.

With all these firefighting operations that take place all over the world in midsummer, it is unheard of to load the water in a container coupled with the pump onto a vehicle and transport it to the source of the fire, where the firefighting teams can tackle the fire from the driver's cab using a monitor on the roof. Although the fire service has fire engines, most of them are not suitable for such an operation. Firstly, the water tanks are mounted on the chassis of the truck, so they cannot be removed. In addition, the tanks are designed to hold 3,000 to 6,000 liters of water, and secondly, most of these trucks are not equipped for off-road use.

The object of the present invention is to create a transportable container for transporting fire extinguishing agents and fire extinguishing equipment, which contains an autonomous fire extinguishing system and can be transported to fire sources using conventional means of transport without additional transport devices.

This object is achieved by the characterizing features of claim 1.

The solution according to the invention ensures an autonomous fire extinguishing system for the transport of fire extinguishing agents and for the use of fire extinguishing equipment at the source of the fire, whereby the fire extinguishing system is transported by means of conventional means of transport, i.e.

can be transported by trucks, tracked vehicles, helicopters or ships without additional structures being required to accommodate the device. The device according to the invention is particularly suitable as a heel roll-tilt system in conjunction with trucks and tracked vehicles that are equipped with a suitable device for accommodating an ISO container.

As a result of the use of a container with standardized dimensions, the basic possibility arises of using the device according to the invention in connection with rail, road and waterway vehicles that can accommodate and transport standard 20-foot ISO containers. In this case, the basic possibility exists of either working at the source of the fire with fire extinguishing equipment provided separately on the container or of using the container as a means of transport for fire extinguishing agents that can be

WASlOl Page 9

Can be connected to the fire extinguishers provided on the vehicle and can be used in this connection at the source of the fire.

This fire extinguishing system based on an integrated handling, storage and transport system makes it possible to fight forest, moor and steppe fires more effectively and cost-effectively.

In addition, it is possible to load or unload this heavy load onto a truck using a roll-on-roll-tipper system, whereby the 20 ton liquid slowly distributes the pressure on the rear wall. This effectively prevents this fire extinguisher container filled with extinguishing water or other liquids from bursting.

Figure 2 is a partially sectioned plan view of the fire extinguisher container;

Figure 3 is a partially sectioned view of the rear of the fire extinguisher tank;

WHAT 101

Figure 4 is a schematic view of the front of the fire extinguisher container;

Figure 5 is a section through the fire extinguisher container along the line A-A according to Figure 2;

Figure 6 is an enlarged detail view X according to Figure 1 and

Figure 7 is an enlarged detail view of detail Y according to Figure 1.

The fire extinguisher container 1 shown in Figure 1 in a side view and in Figure 2 in a top view is cuboid-shaped, in particular as an ISO container, and has two side surfaces 11, 12, a top surface 13 and a bottom surface 14 and two end surfaces 15, 16.

The container 1 is divided into six chambers I to VI by a longitudinal bulkhead 30 and two transverse bulkheads 32, 33 and a front wall 31 and rear wall 34. The chambers I to VI are connected to one another by openings 71 to 73 in the longitudinal bulkhead 30 and, as shown in Figure 5, by openings 74 to 76 in the transverse bulkheads 32, 33, so that an extinguishing agent, preferably water, filled into the chambers I to VI can flow from one chamber to another without the water being able to slosh back and forth unhindered inside the container during travel movements and thus impair the transport stability of the container 1.

WASlOl Page 11

A lifting and pulling bracket 3 is provided on the front side of the container 1, which can be connected to a suitable lifting device so that the container 1 can be pulled onto any transport vehicle. Longitudinal supports 35, 36 arranged on the bottom surface 14 of the container 1 according to Figure 5 are used for the sliding movement of the container 1 over rollers arranged at the rear of a transport vehicle, which at the same time increase the stability of the container against bending.

On the rear side of the container 1, a machine room 2 is provided in which a suction fire extinguishing pump 7 according to Figure 1 can be arranged, which enables autonomous operation of the fire extinguishing container. On the top surface of the machine room 2, a device 8 for receiving a portable pump (monitor) is provided and is connected to the suction fire extinguishing pump 7 via a connecting line 65.

Two openings 51, 52 are provided in the cover surface 13 of the container 1, which can be closed with access hatches 53, 54, so that a maintenance person can access the interior of the container via this manhole. At the same time, filler necks (not shown in detail) are provided in the access hatches 53, 54, through which the fire extinguishing agent can be filled into chambers I to VI.

Additional connecting, filling and removal nozzles 61, 62, 63 are arranged on the front and rear sides of the container 1, through which fire extinguishing agents are fed into the container 1

WASlOl Page 12

can be filled into or removed from chambers I to VI of the container.

Additional stiffeners 21 to 25 serve to increase the stability of the vessel 1 and are attached to the deck and side surfaces of the vessel 1 as well as to the longitudinal and transverse bulkheads.

Figure 3 shows a rear side view of the fire extinguisher container and illustrates the arrangement of the suction fire extinguishing pump 7 in the engine room 2 as well as the arrangement of the filling and discharge nozzles 62 to 66 and two foam extinguishing tanks 81, 82 arranged in the floor area of the engine room 2.

Figure 4 shows a front view of the fire extinguisher container with the lifting and pulling bracket 3 for receiving the container by means of a lifting device on a transport vehicle wherein parts of the chambers I and IV are arranged to the right and left of the lifting and pulling bracket 3, which extend to the front of the fire extinguisher container. Longitudinal beams 35, 36 are arranged on the bottom of the fire extinguisher container as support and sliding rails, which serve to receive the fire extinguisher container on a transport vehicle and at the same time increase the stability of the fire extinguisher container.

A connecting piece is used to connect the fire extinguisher container with a fire extinguisher that is installed in the transport vehicle, so that via this connection the fire extinguisher, for example a monitor arranged on the roof of the driver's cab of a truck, can be monitored via

WASlOl Page 13

a suitable connection can be made to the connecting piece 61, which sucks the fire extinguishing agent from the chambers I to VI of the fire extinguisher container.

Figure 5 shows a section through the fire extinguisher container along the line A-A according to Figure 1 and illustrates the stable construction of the fire extinguisher container with additionally attached stiffeners 21, 23 and the support rails 35, 36 on the base 14 of the container. Openings 74, 75, 76 provided in the cross protection serve to equalize the liquid between the individual chambers I to VI of the fire extinguisher container.

The details shown in Figures 6 and 7 illustrate the structural design of the fire extinguisher container in the floor area of the front and rear sides of the fire extinguisher container.

Figure 6 shows an enlarged detail X according to Figure 1 with an intermediate piece 93 and bottom supports 91, 92 as well as a rib for stiffening the bottom of the container.

Figure 7 shows an enlarged detail Y according to Figure 1 of the front corner area of the base of the fire extinguisher container with a front plate 95, a longitudinal beam 96 and connecting plates 97, 98. A stiffener 99 serves to increase the stability of the construction and a node 100 for corner connection. A base plate 101 serves to delimit the interior of the fire extinguisher container in the area of chamber IV according to Figure 2.

The fire extinguisher container is divided into 6 chambers by two transverse and one longitudinal bulkhead, which are connected to one another. This prevents the water from pressing with full force against the front wall of the fire extinguisher container when the truck brakes hard. The same pressure equalization is achieved when the fire extinguisher container is removed from the truck, which is done using a multi-lift process. The longitudinal bulkhead used in the fire extinguisher container prevents it from tipping over sideways on winding roads and uneven terrain.

The fire extinguisher container is divided into three parts: 5000 mm as a water tank, capacity approx. 20,000 litres, with a screw wall, 1010 mm as the engine room. A foam extinguisher tank approx. 500 mm wide, approx. 500 mm high, approx. 1000 mm deep is installed at the bottom of the rear. The filling opening is on the left side. In the engine room there is 1 air grille on each side. The engine room has 2 lockable doors. A portable pump is attached to the foam extinguisher tank in a U-frame.

There are two access hatches on top of the cover plate of the fire extinguisher container. In the covers of the access hatches

WASlOl Page 16

Filling nozzles are attached to the tanks in the size of an α-pipe. The extinguishing water is pumped into the tank using a suction and extinguishing pump. A compensating valve ensures that the tank does not burst or be crushed by a vacuum when the extinguishing water is sucked out.

There are filling connections with ball valves at the front and rear of the fire extinguisher container, to which other fire extinguisher containers can be connected.

The fire department's standardized portable pump can be integrated into the rear of the fire extinguisher container if necessary. Connections from the water tank allow the extinguishing water to be pushed out through a monitor mounted on the roof of the fire extinguisher container. The firefighter has the option of fighting the fire without laying out water hoses, with full power pressure of 8-10 bar and a water throw range of 70 - 80 m.

A water shut-off valve for the intake pipe size A is on the inner machine wall. Hose connection to the intake fire pump. A B-pipe goes from the machine room to the container roof. A removable monitor is attached to the fire extinguisher container roof. 2 B-hoses go from the portable pump to a monitor T-piece. Both pressure hoses size B combine to form a pressure hose on the monitor. The monitor can be operated manually by a person on the roof of the fire extinguisher container. A device for handling by remote control is planned. Climbing onto the fire extinguisher container is via a collapsible ladder, which is hooked onto the fire extinguisher container if necessary.

WASlOl Page 17

Filling of liquid fire extinguishing water through two openings on the fire extinguisher container, so-called manholes, 400 and 600 mm, 2 pressure valves on the fire extinguisher container. On the front walls of the fire extinguisher container there is a slide valve for connecting an A-suction hose, intended for connecting several fire extinguisher containers to one another.

The fire extinguishing container is given stability by stiffeners that are installed inside the container at intervals of approximately 500 mm. The foam extinguishing additive is connected to the monitor in the engine room using a suction hose. The foam extinguishing tank is connected to the main tank by a valve. If necessary, the foam extinguishing tank can be filled with fire extinguishing water only.

In the event that the fire extinguisher container does not need to be removed from the truck, the fire-fighting operation can be carried out using the vehicle. During this extinguishing process, the firefighter sits in the driver's cab and operates the monitor on the roof of the driver's cab from inside. The portable pump in the rear is then out of action. A suction and pressure pump installed in the truck then takes over the task as soon as the hose connection between the fire extinguisher container and the truck is established.

When extinguishing a fire using foam, two foam tanks are installed at the rear of the fire extinguisher container. These are connected to the main tank by ball valves.

The engine room of the fire extinguisher container is equipped with air filters. This guarantees that the fire brigade portable pump does not overheat.

WASlOl Page II

Below the fire extinguisher container there is a device for loading it onto a truck using a forklift truck. The fire extinguisher container can also be placed on a container ship or pallet (Fiat) and lifted onto a truck using a roll-off tipping system.

The current fire extinguishing container is designed in such a way that it can be placed on a truck without a Fiat (pallet) or container sled.
10

The walls of the fire extinguisher container are smooth on the outside and painted red.

The 20' fire extinguishing container is equipped with the device that allows the fire extinguishing container to be loaded onto container ships.

The fire extinguisher container invented is designed to hold 20,000 liters of water. It can be pulled onto a truck using a multi-lift. When the truck is empty, the fire extinguisher container is transported to the water source, set down, a full fire extinguisher container is picked up and transported to the source of the fire. Many minutes are saved with this procedure. In addition, depending on the size, a fire extinguisher container costs between a fifth and a tenth of the cost of a fire extinguisher tank vehicle.

If the fire has spread further so that wheeled vehicles cannot operate in the area, the operations manager has the option of ordering level II, i.e. the fire-fighting operation can be carried out using armoured tracked transport vehicles.

WASlOl Page 19

Trakehner vehicles can be used as tracked vehicles. They are designed so that the firefighting teams can drive closer to the source of the fire. The vehicle is equipped with a water sprinkler system so that a constant temperature keeps the vehicle mobile, as well as the operating crew in the driver's cab, which is supplied with fresh air from compressed air machines. With such a Trakehner vehicle it is possible to topple trees up to a diameter of 50 cm.
10

The fire extinguishing operation at level II proceeds as follows:

Fire extinguisher containers are filled at the water intake point. Trucks drive the fire extinguisher containers to the forest fire, where the Trakehners take over the extinguishing water and drive it to the emergency room. The extinguishing process now takes place from the Trakehner's driver's cab. A hose connection is made between the fire extinguisher container and the vehicle via a suction and pressure pump that is installed in the vehicle. The firefighter can now operate the monitor on the roof from the driver's cab. He now has 45 bar water pressure at his disposal with a water surge of 4,500 l per minute.

If the fire extinguisher container is empty, it is parked at the edge of the forest to be filled. If the soil structure allows the Trakehner to carry a fire extinguisher container trailer, this results in a water supply of 80,000 litres. Otherwise, a rotation process takes place, in which, for example, 20 fire extinguisher containers are in use and 20 fire extinguisher containers are empty on their way to the water intake point, while 20

WASlOl Page 2 0

Fire extinguisher containers are filled with extinguishing water at the water point and 20 filled fire extinguisher containers are on their way to the source of the fire. This can be increased in number as required. This ensures flexible fire fighting at the source of the fire.

The invention is not limited in its implementation to the preferred embodiment given above. Instead, a number of variants are conceivable which make use of the solution presented even in fundamentally different designs.
