FIREFIGHTERS DRONE ARRANGEMENT Description of the Invention
Technical Field of Invention
This invention relates to an arrangement for a set of drones to be used in fighting fires in high buildings, or unreachable forests.
Firefighting is an act of extinguishing fires, the firefighter is a highly trained proffessional with high technical skills, adopting firefighting techniques. A fire can rapidly spread and endanger many lives; major hazards associated with fires are: smoke, Oxygen deficient atomosphere, elevated temperatures (immense heats until far destances), and toxic atomospheres, all of these are creating difficulties for fire fighters to operate smoothly, it also make the working environment dangerous for them, and creating situations that are sometimes unexpectable, or hard to control.
There are two differrent types of fires that are hard to reach. First: burnt flats in high rise buildings that are blowing down burned materials, and sending up heat and smoke, spreading the fire up, and dropping hot materials, which set fire in lower sides. Second: Fires that are unreachable inside forests, where the terrain is too rugged, or too remote for the firefighters to get access to them, in addition to the heat and smoke spread, and the danger that fire surrounds the firefighters.
The solution for the first type was to use a pressurized fire hydrant, bumping a straight spray toward the high burning flat, or using a boom to guide the hose up toward it, while the solution for the second one was via areial fire fighting, which uses fixed-wing (airtankers, water bombers) carrying until 90,000 liters like in super tankers, or helicopters (manned aircraft) carrying a water tank (3,000 liters) to drop water ahead of the moving fire, or along its edge to create an artificial firebreaks. Helicopters are fitted with tanks (helitanks) or carrying buckets, or outfitted with a front mounted foam cannon. Even these fire fighting tools are successful, but it can not provide a contineous water spray against a
fire, sometimes it lacks the control, or the water can spread and evaporate, also water can not be sprayed toward the front side or seat of the fire.
Due to the risk, security, safety, and dangers of the firefighting processes; remotely controlled fire fighting is not yet taking place, drones are suggested to be used in fire fighting, but that was based on simple tasks, using a camera for normal or thermal imaging of the fire locations that are difficult to be viewed from the ground, while others are suggesting simply that a drone carry a water hose to excute a special fire fighting task.
But this still obvious for a person skilled in the art, even drones are not used yet, because similar firefighting systems to be used by helicopters or drones were invented. German Patent DE20315789 is disclosing a Forest fire-fighting blanket to be deployed over the heart of the fire by a helicopter or unmanned drone. A fire fighting helicopter is disclosed too in US patent No. 4090567.
The closest to art, is US patent No. 5135055, titled Ground and airborne fire fighting system and method of fighting high rise building fires, a helicopter is carrying a hose up from a ground vehicle, to face the floor into which the fire is located, to direct the water into the flat, until a fire crew can arrive at the scene. This last invention requires tbringing a manned helicopter from its base, to have an access in-between the buildings (landing and flying), while ignoring the dangers of the highly propelled air by the propeller of the helicopter, which will blow the hot smeke and the burnt material around, increasing the chances for creating extra fires around, unforgetting the installation and removal procedures for the hose into the helicopter will be a time consuming.
Drones can be more compact fire fighting apparatuses, but if one drone alone carried hardly a hose for fire fighting task in a flat or a floor, the extension of the hose of water under the drone can bent toward the building for many reasons, where it can become in contact with a heated surface, damaging the hose.
Inside forests, a drone can not alone carry a water hose, neither it can prevent it from arcing (bending down) toward the trees, where it will either get stuck, or get overheated and damaged.
But still a set of drones with a suitable arrangement, can carry out a fire fighting task smoothly, safely, and efficiently. This is disclosed in this invention.
Disclosure of Invention
To provide an arrangement for a set of drones to carry out a remotely controlled unmanned fire fighting process, against a far to reach burning flats in high rise buildings, or a terrain inside a forest.
The arrangement used to carry out extinguishing of a fire in a flat in a high rise building, is based on four drones fixed and installed conventionally over a firefighting tanker, wherein each two drones are launched together up, by releasing them from their bases over the tank, each two drones are carrying the hydrant up such that one of them is the leader drone carrying the tip of the hydrant toward the fire, while the second drone is the supporting drone, carrying the extension of the hydrant behind the leading drone, such that the hose would not bend toward the building and face a high chance of being burned and damaged. Two sets of drones are arranged in parallel toward the fire to compensate for the lower diameter of carried hoses, but with providing an attack toward the fire from different angles or sides.
The same arrangement is used to carry out extinguishing of a fire in a far terrain, but with extra number of drones carrying each hose, such that each set of these drones, create nearly an arced hose over the blocking terrain until reaching the front edge of the fire, these arrangements can go deeply for hundreds of meters inside a forest, to provide a continuous pressurized water against the fire, multiple arrangements depending on trucks providing tens of cubic meters of water, can work together too.
These drones which are carrying cameras, for assessing the fire conditions, are controlled either autonomously by broad computers, or by remote control of a pilot on the ground or in a vehicle, they are too can be launched automatically from their bases over the tanks.

Best Mode for Carrying out the Invention:
In order to make it easy to carry out the invention, a detailed description of the parts of the invention, supported with figures, is provided here, wherein the main parts are arranged sequentially, according to the importance of the part, we made it easy to read, by referring to each feature, with a number included in the parts description text, and in the parts numbering list, the numbering of parts features is indicated here, by starting it sequentially from number 20, whenever a part feature appears in a text, it will be directly assigned its required serial number. As example in FIG. 1, the parts' features are arranged sequentially from number 20, 21, 22...
1- Extinguishing fire out of a flat in a High rise building (Fig.s 1, 2, 3, 4):
The firefighters drones arrangement 20 used to carry out
extinguishing of a fire in a flat in a high rise building, is based on four drones 21, wherein each two drones 21 are installed after the other, from the rear toward the front, over a firefighter truck's 22 tank 23, and the two sets 24 are installed parallel to each other. Each drone 21 is fixed and installed conventionally over a firefighting tanker 22, wherein each two drones 21 are launched together up, by releasing them from their bases over their installation locations (base) 25 over the top surface of the tank 23, each two drones 21 are carrying the hydrant 26 up through a ring carrier 27, installed on their body bottom side, while a monitoring camera 28 too is installed on the bottom of each drone 21 to view and monitor the firefighting procedure.
For each set of drones 21 carrying one hydrant 26, one of them is to be the leader drone 29 carrying the tip of the hydrant 26 toward the fire, while the second drone is the supporting drone 30, carrying the extension of the hydrant 26 behind the leading drone 29, such that the hydrant hose 26, would not bend toward the building, and as a result faces a high chance of being burned and damaged due to getting in touch with a hot surface. Two sets of drones 21 per truck 22 are arranged toward the fire, to compensate for the small diameter of each of the carried hoses 26, but this arrangement provides an efficient attack toward the fire from different angles or sides.
- Extinguishing of a fire in a far terrain (Figs. 5, 6): in the same like in point one, but with bigger drones 21, but with extra number of drones installed and arranged in one line, along the top surface of the firefighting tank 23, each truck 22 carries one arrangement of drones 20, such that they are carrying one hose 26, wherein these drones 21 create nearly an arced hose 26 in the air, over the blocking terrain, until reaching the front edge of the fire, multiple sets of arrangements provided by multiple no. of trucks 22, can go deeply for hundreds of meters inside a forest, to provide a continuous pressurized water 31 against the fire, multiple arrangements 20 depending on trucks 22 providing tens of cubic meters of water, can work together.
Note: The hydrant (hose) 26 is carried up by each drone by passing it through a ring carrier 27, installed at the bottom of the drone 21.
Cameras 28 fixed on drones 21 can replace the so-called Air Attack, who is a Tactical Group Supervisor, usually flying at an altitude above other resources assigned to the fire. The cameras 28 can be used for assessing the fire conditions, cameras are controlled either autonomously by broad computers, or by remote control of a pilot on the ground or in a vehicle, they are too can be launched automatically from their bases over the tanks 23.
Note: the drones 21 can be installed from down side by having conventionally a connection locked to inside a suitable cylindrical housing 32 (Fig. 2), being protruding or grooved in the on-tank support base 33, wherein the ring carrier 27, and camera 28, are inserted inside this housing 32, while the drone 21 is not in use.
1- Multiple sets of drones arranged sequentially and conventionally to carry and support a hydrant toward a fire.
2- These drones, hoses, installations are made from available tools, parts, mechanisms, with applicable modifications.
3- Arrangements of drones suitably installed and fixed on the top surface of tankers without the need for special trucks to ship or transport them.
4- Arrangements of drones while in use, such that a hard to approach fire source, can be approached smoothly, fast, safely, with an efficient firefighting procedure without losing the pressure of the water or foam, and with extra capability to maneuver against the fire from many sides and many angles.
5- These drones arrangement can be connected directly to hydrants inside the forest, without the need for a tanker.
6- Multiple shapes of arrangements can be created based on the use of multiple drones, to carry out different specific civil service tasks.
7- Arrangement of drones for multiple use options in irrigation, agriculture...etc
