Description

A system for combating forest fires
The present invention relates to a system for combating forest fires, especially in hard-to-reach places.
The equipment that is usually used has a small capacity both in terms of water supply and the way hoses and other equipment are driven out. For forest fires in "land-hill" areas, systems with lighter vehicles such as ATVs and iron horses are often used. Where there are passable roads, fertilizer wagons from agriculture are also used. These have a limited ability to leave forest roads, and thus the extinguishing capacity is limited to a few tens of meters from the roadside. Furthermore, a patent for a pickup with a water tank, hose reel and motor-driven pump mounted on the loading platform is known from US patent 4593855. Here, neither accessibility nor water volume will be sufficient in roadless areas. US 2005/0126631 Al discloses a similar device in which the vehicle is divided into a two-wheeled tractor and a two-wheeled truck which are interconnected by a universal joint and a mechanical drive shaft for transmitting power to the rear wheels. The truck includes a fixed, prismatic water tank. A water pump, a generator for operating the water pump and a hose reel are mounted thereon. The device has limited capacity, as it must be light enough to be transported by helicopter to the place of operation.
The object of the invention is to remedy the above-mentioned shortcomings. This is achieved with a system as defined in the patent claims.
For a better understanding of the invention, it is illustrated in the following by means of exemplary embodiments illustrated in the appended, partly schematic drawings, in which
Figure 1 is an elevation of a loading tractor provided with a part of the equipment in the system according to the invention;
Figure 2 is a section of Figure 1 on a larger scale;
Figure 3 is a perspective view of a loading tractor provided with another part of the equipment in the system according to the invention; and Figure 4 shows a helicopter handling a further part of the equipment in the system according to the invention.
Figure 5 is a diagram of the water system for the equipment shown in Figures 1 and 2.
Figure 6 shows an alternative embodiment of the equipment shown in Figure 1.
Figure 7 is a partly exploded perspective view of the embodiment in Figure 6.
Figure 1 shows a timber log loading tractor 1 which has a towing vehicle 2 and a trailer 3 provided with a loading crane 4 for loading logs onto the trailer's loading section 5. The loading tractor has driving power on all four pairs of wheels for maximum maneuverability. An extinguishing rig 6 is arranged on the loading section 5 and has a first platform 7 which carries a water tank 8. The volume of the tank can be approximately 10 m3. The platform 7 also carries a hydraulically driven hose reel 9, which in the example shown is arranged behind the water tank 8.
Other locations on the extinguishing rig may also be suitable. An additional hose reel 10 is mounted on the front of the towing vehicle 2.
Figure 2 shows more details of the platform 7. A water cannon 11 is mounted on the water tank 8 and can be remotely controlled to cover the entire area around the loading tractor 1. Thereby, the loading tractor can move close to the fire and have the possibility to escape if it should be trapped by an unexpected development of the fire. With some additional equipment the water cannon can also be used for screening.
A water pump 12 is further mounted on the platform 7, which supplies extinguishing water to a manifold 13 for connection to fire hoses and to the water cannon 11. The pump is driven by a hydraulic motor which is powered by the hydraulic system of the towing vehicle 2. The pump can be self-priming and used to fill the water tank 8 from a nearby source, such as a pond, a stream, or a river. A separate pump may also be installed for this purpose.
Figure 3 shows another part of the equipment according to the invention. Here, the loading section 5 of the loading tractor 1 is provided with a hose rig 14, which comprises a second platform 15 which carries a plurality of hose reels 16 and their control equipment. Figure 4 shows a helicopter 17 carrying a special hose reel 18, which is arranged such that the hose can be pulled off the reel by means of the helicopter. This is useful in situations the loader tractor 1 with the hose rig 14 cannot reach.
Figure 5 is a diagram of the water system on the first platform 7. Here is shown a water pump 12 driven by a motor 19, preferably hydraulic. The pump receives water from the water tank 8 and can supply it to the fire hose manifold 13, to the water cannon 11, or back to the tank, depending on how the valves 20-23 and the valve of the water cannon (not shown) are set. If only the valves 20 and 22 are open, the water is sent only to the manifold 13. If only the valves 21 and 23 are open and the pump is self-priming, it will suck water from the source 24 and fill the tank 8.
Figure 5 also schematically shows the hose reel 9 with hose 25. The reel is rotated with a reversible motor 26, so that the hose can be paid out or retracted. The motor shaft can be engaged by a brake 27.
In Figures 6 and 7 showing the alterative embodiment, similar parts are given the same reference characters as in Figure 1. Here, the water tank is replaced by six cubical tanks 28, preferably made of a polymer material and reinforced by a metal cage 29. The tanks 28 are placed in a frame 30 which rests like a platform on the loading section 5. Underneath the tanks 28 the frame 30 has a main tank 31 to which the outlets of the tanks 28 are connected via valves. The main tank feeds the water pump. The tanks 28 are filled through an opening 32 in the top thereof, preferably provided with a non-return valve. The tanks 28 may be loaded onto the frame 30 by means of the crane 4 in either empty or filled condition. The openings 32 may be arranged to permit filling by a helicopter.
The extinguishing rig 6 is further provided with a compressor 33 for loading air bottles 34 for firemen combatting e.g. a tunnel fire. The platform also comprises a fan 35 for clearing smoke from the operator area or tunnel opening. Both the compressor and fan are connected to flexible hydraulic lines 36 to permit suitable positioning thereof. A foam extinguisher may be provided as well.
It will be understood that the term "platform" 7 used here and in the claims is not intended to be limited to a planar object but is to cover any kind of load-bearing frame or chassis for the equipment and is preferably adapted to the distance between the ordinary log bunks of the loading section 5. It will also be understood that the protection provided by the patent is not limited to the exemplifying embodiments above but is defined by the terms of the claims and equivalents thereof.
