Description

Technical Field

[0001] The present invention relates to a transportation method and a transportation system, and more specifically, to a method and a system for transporting a fire extinguishing agent used in wildfires and high-rise building fires that occur frequently worldwide by an aircraft.

Background Art

[0002] Conventionally, the fire extinguishing method has always been to extend a fire hose from a fire truck and for a person to approach the fire and extinguish the fire with a hose held by hand. Therefore, there was a risk to the lives of firefighters as they tried to approach the fire. Also, in the case of the automatic nozzle installed on the fire truck, since there is a distance between the water and the fire, there is a drawback that the water atomizes and the fire extinguishing ability decreases.

[0003] As a method of extinguishing a fire without a person, it has been proposed to drop a fire extinguishing agent from an unmanned aircraft such as a helicopter or a drone (see Patent Document 1 below), or to connect a fire hose to a drone and lift a nozzle to a high place of a building and discharge water (see Patent Document 2 below).

Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, in the fire fighting technology according to the prior art, it was almost impossible to extinguish a large wildfire. Also, there was a risk to firefighters as they tried to approach the fire. For this reason, there was no effective fire extinguishing method, and a vast natural environment was being destroyed by wildfires.

[0006] Specifically, attaching a parachute to a fire extinguishing agent dropped from a helicopter as in Patent Document 1 is considered to have a certain significance for extinguishing wildfires. However, since helicopters have difficulty in flying speed, it is difficult to quickly transport the fire extinguishing agent. Also, lifting a nozzle with a drone as in Patent Document 2 may be useful for dealing with high places such as building fires. However, a water source for fire extinguishing water needs to be present nearby, and it is impossible to deal with wildfires where it is difficult for vehicles to enter.

[0007] Although the extinguishment of wildfires was used as an example above, in addition to that, it is desired to quickly deliver relief supplies and rescue team members to the disaster area.

[0008] The present invention has been made in view of such points, and its object is to quickly transport a large-weight object to be transported even to a destination where ground transportation is difficult.

Means for Solving the Problem

[0009] The present invention is a method of transporting an object to be transported by an airplane, wherein the object to be transported has a holding part, the airplane has a capturing part that can be connected to the holding part, when the airplane flying in the traveling direction at a speed higher than that of the preliminary acceleration device overtakes the preliminary acceleration device on the ground traveling in the predetermined traveling direction with the object to be transported mounted thereon, the holding part of the object to be transported is connected to the capturing part to transfer the object to be transported from the preliminary acceleration device to the airplane, and the transferred object to be transported is transported by the airplane.

[0010] Also, the present invention is a transportation system for transporting an object to be transported by an airplane, a preliminary acceleration device on which the object to be transported is mounted and traveling on the ground in a predetermined traveling direction, and the airplane that can fly at a speed higher than that of the preliminary acceleration device and can transport the object to be transported, the object to be transported has a holding part, The airplane has a catching part that can be connected to the holding part. When the airplane flying in the traveling direction at a speed higher than that of the preliminary acceleration device overtakes the preliminary acceleration device, the holding part of the object to be conveyed is connected to the catching part to transfer the object to be conveyed from the preliminary acceleration device to the airplane, and the transferred object to be conveyed is conveyed by the airplane.

Advantages of the Invention

[0011] According to the conveying method and the conveying system of the present invention, an object to be conveyed preliminarily accelerated by a preliminary acceleration device is connected to an airplane in flight and conveyed thereby. Therefore, even an object to be conveyed with a large weight can be quickly conveyed to a destination by the airplane.

Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, corresponding components are given common reference numerals, and overlapping explanations are omitted as appropriate.

[0014] FIG. 19 is a diagram for explaining the transport system of the present embodiment. Specifically, it shows a state in which the carrier 110 at the front of the preliminary acceleration device (vehicle 108) traveling at high speed accelerates the fire extinguishing unit 53, which is the object to be transported. It also shows a state in which the object to be transported (fire extinguishing unit 53) is connected to an airplane (jet airplane 98) that overtakes the preliminary acceleration device (vehicle 108).

[0015] That is, the present embodiment is a transport system (hereinafter, may be referred to as "this system") for transporting an object to be transported (fire extinguishing unit 53) by an airplane (jet airplane 98). This system includes a preliminary acceleration device (vehicle 108) and an airplane (jet airplane 98). The preliminary acceleration device (vehicle 108) travels on the ground in a predetermined traveling direction with the object to be transported (fire extinguishing unit 53) mounted thereon. The airplane (jet airplane 98) has a propulsion force that can fly faster than the preliminary acceleration device (vehicle 108) and can transport the object to be transported (water tank 50). The object to be transported (water tank 50) has a holding part (kite 76 and pickup cable 74), and the airplane (jet airplane 98) has a capturing part (detachable hook 72) that can be connected to this holding part (kite 76 and pickup cable 74). When an airplane (jet airplane 98) flying in the traveling direction of the preliminary acceleration device at a speed higher than that of the preliminary acceleration device (vehicle 108) overtakes the preliminary acceleration device (vehicle 108), this system connects the holding part (kite 76 and pickup cable 74) of the object to be transported (water tank 50) to the capturing part (detachable hook 72) to transfer the object to be transported (fire extinguishing unit 53) from the preliminary acceleration device (vehicle 108) to the airplane (jet airplane 98). Then, the transferred object to be transported (fire extinguishing unit 53) is transported by the airplane (jet airplane 98).

[0016] Hereinafter, this system will be described more specifically.

[0017] The transport destination to which the object to be transported is transported by this system is not particularly limited to a fire site such as a mountain fire, but may also be a disaster area affected by natural disasters, an accident site, etc. In the present embodiment described below, the case where the transport destination is a fire site is exemplified. The object to be transported is not particularly limited and can be an object and / or a person. In this embodiment, the object to be transported to the fire site includes a fire extinguishing agent container containing a fire extinguishing agent. The fire extinguishing agent may be a fluid liquid such as water, or may be in a foam form or a powder form. More specifically, the object to be transported in this embodiment is a fire extinguishing unit 53, which includes a fire extinguishing agent container (water tank 50) for containing a fire extinguishing agent (water), a fire hose 6 connected to the fire extinguishing agent container (water tank 50), and a nozzle portion 16 provided at the tip of the fire hose 6 for injecting the fire extinguishing agent (water). The fire extinguishing unit 53 will be described in detail later.

[0018] As an example of the airplane, a jet plane 98 is illustrated, but a propeller plane may also be used. Since an airplane having a cargo hold such as the Kawasaki C-2 transport plane is expensive, a small light airplane such as a normal passenger plane or a Cessna plane may be used. According to this embodiment, such an airplane can also transport the water tank 50 and the cargo to the transport destination.

[0019] Generally, a speed of 250 km / h to 300 km / h is required for the airplane to take off. However, since the propulsion force of the airplane is limited, if a heavy object to be transported is loaded on the airplane from takeoff, sufficient acceleration cannot be obtained, and a long takeoff roll distance and a large amount of fuel are required. In contrast, in this system, a preliminary acceleration device (vehicle 108) is used to sufficiently accelerate the object to be transported, and the object to be transported in this accelerated state is picked up by the airplane. Therefore, the airplane can take off from a normal short runway and can transport a heavy object to be transported over a long flight distance without requiring excessive fuel.

[0020] That is, the conveying method realized by the conveying system of the present embodiment (hereinafter may be referred to as "this method") is a method of conveying an object to be conveyed by an airplane. When a preliminary acceleration device (vehicle 108) on which the object to be conveyed is mounted and travels on the ground in a predetermined traveling direction is overtaken by an airplane (jet plane 98) flying in the traveling direction at a higher speed than this preliminary acceleration device, the holding part (kite 76 and pickup cable 74) of the object to be conveyed (fire extinguishing unit 53) is connected to the capturing part (detachable hook 72) to transfer the object to be conveyed from the preliminary acceleration device to the airplane, and the transferred object to be conveyed is conveyed by the airplane.

[0021] The jet plane 98 is provided with a suspension cable 112 of sufficient length that can be wound up and paid out. A detachable hook 72 is attached to the tip of the suspension cable 112.

[0022] The preliminary acceleration device is a means for accelerating the object to be conveyed by traveling on the ground and reducing the relative speed with the jet plane 98. Here, traveling on the ground includes not only traveling on the ground or road surface by wheels, but also traveling on a track (rail) installed on the ground or traveling in the vicinity of the ground in a magnetic levitation manner.

[0023] The preliminary acceleration device of the present embodiment is a vehicle with a large horsepower, or a carrier 110 is installed at the front or rear of a vehicle 108 equipped with a jet engine 102 or a rocket engine, and travels on tires 109. The water tank 50 loaded on this carrier 110 can be picked up by an aircraft (jet plane 98) at a high speed.

[0024] The holding part is a part of the object to be conveyed and may be rigid or flexible. The holding part may be a part of the water tank 50 or a separate member.

[0025] The holding part of this embodiment has a floating member that rises into the air by the lift force due to the wind pressure received when the preliminary acceleration device travels on the ground. In this embodiment, as the floating member, a kite 76 fixed to the water tank 50 by a rope and a pickup cable 74 provided on the kite 76 are exemplified. The capturing part is a part provided on the airplane and connectable to the holding part. In this embodiment, it is the detachable hook 72. When the capturing part (detachable hook 72) captures the floating member (kite 76 and pickup cable 74) in the air, the holding part is connected to the capturing part. When the detachable hook 72 hanging down from the airplane catches on the pickup cable 74 connected to the kite 76 that has risen into the air, the holding part (pickup cable 74) is connected to the capturing part (detachable hook 72). Here, "connect" includes various modes such as when members catch on each other like in this system, when one member grips the other member, and when members are locked to each other like a connector.

[0026] When the airplane connected to the water tank 50 accelerates, the buoyancy of the kite 76 further increases, and the water tank 50 can be carried into the sky.

[0027] The traveling speed of the preliminary acceleration device when connecting the holding part to the capturing part is greater than the relative speed between the preliminary acceleration device and the airplane. In other words, the traveling speed of the preliminary acceleration device exceeds half of the flying speed of the airplane. In the system shown in FIG. 19, the vehicle 108 is traveling to the left, and the jet plane 98 is flying in the same direction and trying to overtake the vehicle 108. The detachable hook 72 is provided with a vertical fin 77 protruding in the direction opposite to the bending direction of its tip (leftward in FIG. 19) (rightward in the same figure). When the jet plane 98 flies, the vertical fin 77 faces backward, and for this reason, the detachable hook 72 faces forward. Thereby, when the jet plane 98 overtakes the vehicle 108, the detachable hook 72 can stably catch the pickup cable 74.

[0028] Conventionally, systems for retrieving people on the ground using airplanes, such as Fulton recovery systems and skyhooks, have been proposed. These systems involve a lifting rope attached to an airplane that a person on the ground grabs and is lifted up by. However, in this case, since the person being transported is substantially stationary, the relative speed with the airplane is equal to the flight speed of the airplane and is extremely high. For this reason, it is difficult for a person to grab the lifting rope, and since the airplane has to accelerate a stationary object being transported, it is difficult to continue stable flight. Therefore, it is only possible to retrieve objects with a weight equivalent to that of one person. In contrast, in this system, while running a preliminary acceleration device at a speed of at least half of the flight speed of the airplane, preferably at a speed comparable to the flight speed, to move the object being transported forward, the capturing part of the airplane is connected to the holding part of the object being transported. For this reason, the load applied in the direction opposite to the flight direction to the airplane at the moment of connection is small, and the airplane can continue stable flight and transport the object being transported to the destination. The airplane further accelerates to increase lift and raise the water tank 50, transports it to above the fire, which is the destination, releases the connection between the capturing part and the holding part, and drops the object being transported from the airplane.

[0029] The floating member (kite 76) receives lift from the wind pressure received by the object being transported dropped from the airplane and decelerates the object being transported. As a result, the object being transported falls to the destination such as a fire site in a state decelerated more than free fall. Also, a dropping parachute 52 is provided in the water tank 50. After the water tank 50 is dropped from the airplane, by operating an operating device (not shown) in the air to deploy the dropping parachute 52, the object being transported can be further decelerated and safely dropped to the destination.

[0030] The kite 76 may be singular or plural. When the kite 76 is singular, the pickup cable 74 may be fixed to both ends thereof and looped. Also, when there are multiple kites 76 (two), the pickup cable 74 may be stretched between them (see Fig. 13). Alternatively, without providing the pickup cable 74, the kite 76 may be hooked and captured by the capture part (detachable hook 72).

[0031] The detachable hook 72 will be further described. The detachable hook is a variable hook, and the hooking mode and the dropping mode can be selectively set.

[0032] Fig. 21 is a diagram showing the ON state of the detachable hook 72, i.e., the hooking mode. The detachable hook 72 is fixed to the lower end of the suspension cable 112 hanging from the airplane, and the hook control shaft 126 is extended and moved downward by the hook control unit 132. The hook control shaft 126 is the drive shaft of a hydraulic cylinder, and the hook control unit 132 is the control device of the cylinder. When the hook control shaft 126 extends, the link mechanism operates to lift the detachable hook 72 and hook the pickup cable 74.

[0033] Fig. 22 is a diagram showing the OFF state of the detachable hook 72, i.e., the dropping mode. When the hook control unit 132 is activated to shorten and raise the hook control shaft 126 from the hooking mode, the tip of the detachable hook 72 faces downward due to the operation of the link mechanism and the pickup cable 74 drops.

[0034] Hereinafter, the fire extinguishing unit 53 will be described in detail.

[0035] Fig. 12 is an explanatory diagram of the fire extinguishing unit 53. The fire extinguishing unit 53 of the present embodiment is a water tank 50 to which a fire hose 6 provided with a nozzle part 16 having a self-propelled head 19 is connected at the tip. The water tank 50 with the self-propelled head 19 is equipped with a dropping parachute 52, which is dropped in the mountain fire area at the destination and can land in the fire with the dropping parachute 52. An underwater pump 60 is built into the water tank 50 and operates after landing. Water is sprayed from the self-propelled head 19, and the self-propelled head 19 moves upward while extinguishing the fire. The underwater pump 60 is operated by an internal combustion engine or a combination of a battery and a motor (not shown), pumps up the water in the water tank 50, and discharges it from the nozzle portion 16. A camera (not shown) may be built into the water tank 50, or the movement of the self-propelled head 19 may be controlled while observing the fire scene with a drone to extinguish the fire. One or more fire hoses 6 provided with the self-propelled head 19 can be provided on the water tank 50.

[0036] The fire hose 6, which is part of the object to be conveyed, will be described. FIG. 1 is a perspective view of the fire hose 6 provided with the alternating valve 26.

[0037] In addition to the water tank 50 filled with water 1, which is a fire extinguishing agent, the object to be conveyed by the present system and method further includes one or more propellant containers 51 each filled with one or more types of propellants, and an alternating valve 26 capable of selectively switching the internal flow path. The fire extinguishing agent container (water tank 50), the propellant container 51, and the nozzle portion 16 (see FIG. 2 etc.) communicate with each other via the alternating valve 26 and the fire hose 6. The ejecta ejected from the nozzle portion 16 can be switched to either a fire extinguishing agent or one or more types of gaseous propellants by switching the alternating valve 26.

[0038] Hereinafter, the object to be conveyed will be described in more detail. As shown in FIG. 1, the inner side of the fire hose 6 is branched into five branched hoses, and there are flow paths for water 1, high-pressure gas 2, jet injection gas 3, rocket injection gas 4, and helium gas 5. Water 1 is a fire extinguishing agent, and high-pressure gas 2, jet injection gas 3, rocket injection gas 4, and helium gas 5 are propellants. By switching the alternating valve 26, any one of the flow paths is selectively connected to the fire hose 6, and the fire extinguishing agent or propellant is discharged from the nozzle portion 16 (see FIGS. 12 and 19). The branched hose for water 1 is connected to the water tank 50, and the branched hose for the propellant is connected to the propellant container 51. Specifically, the propellant container 51 is composed of four tanks: a high-pressure gas tank 51a, a jet propellant tank 51b, a rocket propellant tank 51c, and a helium gas tank 51d. The high-pressure gas 2 filled in the high-pressure gas tank 51a is, for example, nitrogen gas or carbon dioxide gas, has a smaller molecular weight than helium gas 5, and is a gas at normal temperature and pressure. The jet propellant tank 51b is filled with jet engine fuel. A combustor (not shown) is provided in the jet propellant tank 51b, and the combustion gas generated by burning the jet engine fuel in the combustor is supplied as the jet injection gas 3 from the jet propellant tank 51b to the alternating valve 26 of the fire hose 6 as the propellant for the nozzle portion 16. The rocket propellant tank 51c is filled with rocket fuel and an oxidizer. A reactor (not shown) is provided in the rocket propellant tank 51c, and the reaction gas generated by chemically reacting the rocket fuel and the oxidizer in the reactor is supplied as the rocket injection gas 4 from the rocket propellant tank 51c to the alternating valve 26 of the fire hose 6 as the propellant for the nozzle portion 16. The helium gas tank 51d is filled with high-pressure helium gas 5, and this helium gas 5 is supplied as the propellant for the nozzle portion 16 to the alternating valve 26 of the fire hose 6. The fire extinguishing agent water 1 is a liquid, and the high-pressure gas 2, jet injection gas 3, rocket injection gas 4, and helium gas 5, which are propellants, are gases. When extinguishing a fire, water 1 is injected from the nozzle portion 16, and when moving the self-propelled head 19 toward the source of the fire, either the high-pressure gas 2, jet injection gas 3, or rocket injection gas 4 (hereinafter, these three gases may be collectively referred to as "reaction gas") is injected from the self-propelled head 19. However, the non-flammable high-pressure gas 2 and helium gas 5 may be used as fire extinguishing agents. Also, water 1 may be used not only as a fire extinguishing agent but also as a propellant. The fire extinguishing agent or propellant supplied to the nozzle portion 16 (self-propelled head 19) at the tip through the fire hose 6 can be arbitrarily and constantly changed by switching the alternating valve 26 built into the fire hose 6. The switching of the alternating valve 26 is performed by a switching control unit (not shown).

[0039] Figure 2 shows an example of the nozzle portion 16 shown in FIGS. 19 and 12. The nozzle portion 16 shown in FIG. 2 is a T-shaped self-propelled head. The T-shaped self-propelled head 19 has right-side rotary nozzles 7 and 8 and left-side rotary nozzles 9 and 10 at the head, and a left-direction nozzle 11, a right-direction nozzle 13, and a front nozzle 12 are installed. Each is valve-controlled, and position movement by the injection of reaction gas and fire extinguishing by water injection are selectively performed. It is also possible to close all the valves and raise the fire hose 6 with helium gas 5 (see FIG. 1).

[0040] When the gaseous propellant (reaction gas) is injected vertically downward from the nozzle portion 16, a part of the fire hose 6 and the nozzle portion 16 can float against their own weight due to the reaction of the injection pressure being injected. Thereby, when the object of fire extinguishing such as a building fire is at a high place, the nozzle portion 16 can be lifted to a high place. Also, in the case of a mountain fire, the injection range of water 1 can be increased by lifting the nozzle portion 16 to a high place.

[0041] The nozzle portion 16 of the present embodiment automatically detects the relative direction in which the combustion site of the fire is located based on the position of the own vehicle, and self-propels toward the combustion site.

[0042] The self-propelled head 19 of the nozzle section 16 has a plurality of injection ports (right rotating nozzles 7, 8, left rotating nozzles 9, 10, leftward nozzle 11, forward nozzle 12, and rightward nozzle 13) that inject projectiles in different directions, opening and closing means (switching valve 27) for individually controlling the opening and closing of these plurality of injection ports, and a heat-sensitive sensor 31 for detecting the temperature around the nozzle section 16. The right rotating nozzles 7, 8 and the left rotating nozzles 9, 10 can be individually rotated about the rotation axis in the arrangement direction of the leftward nozzle 11 and the rightward nozzle 13 (the left-right direction in FIG. 2). When the control unit 32 determines the direction in which the fire extinguishing agent or the propellant should be injected, it rotates the right rotating nozzles 7, 8 and the left rotating nozzles 9, 10 around the rotation axis as necessary to achieve the desired injection direction. This system includes a control unit 32 that identifies the direction in which a high-temperature heat source exists among the surroundings of the nozzle section 16 from the temperature information acquired by the heat-sensitive sensor 31, and based on the identification result, controls the opening and closing means (switching valve 27) to selectively open a part of the plurality of injection ports and inject a projectile from the injection port.

[0043] The heat-sensitive sensors 31 are provided at a plurality of locations near the surface of the self-propelled head 19. The plurality of heat-sensitive sensors 31 and the control unit 32 are electrically connected to each other. Among the temperature information respectively acquired from the plurality of heat-sensitive sensors 31, the control unit 32 determines that there is a heat source, that is, a combustion site of a fire, in the direction in which the heat-sensitive sensor 31 showing a significantly high temperature exceeding a predetermined noise threshold value is arranged.

[0044] The fire extinguishing method according to this method will be described. When extinguishing a fire, the control unit 32 selects the injection port that it determines is facing the combustion site in the nozzle section 16, and the switching valve 27 opens this to inject water 1. However, the fire extinguishing by this method is not limited to this. When a fire occurs indoors in a building such as a building, in some cases, it may be more efficient to exhaust the air in the room and make it oxygen-deficient rather than spraying water 1 on the combustibles. Therefore, after the propellant is ejected from the self-propelled head 19 and the self-propelled head 19 breaks through the window glass from outside the building and enters the room, the control unit 32 may control the switching valve 27 so that water 1 is ejected toward the outside of the building through the window on the side opposite to the combustion products in the room, that is, the window through which it has entered. In other words, the control unit 32 controls the switching valve 27 so that water 1 (fire extinguishing agent) is ejected in a direction opposite to the heat source as viewed from the nozzle unit 16, and selectively opens an ejection port that opens in a direction opposite to the direction in which the heat source exists with respect to the nozzle unit 16 among the plurality of ejection ports.

[0045] In this way, the fire extinguishing unit 53 used in the present system and the present method, in addition to the first flow path switching means (alternating valve 26) that selects and switches either the flow path of the fire extinguishing agent or the propellant ejected from the nozzle unit 16, has a second flow path switching means (switching valve 27) that selects and switches the ejection ports of the fire extinguishing agent or the propellant ejected from the self-propelled head 19 from a plurality of nozzles (right rotating nozzles 7, 8, left rotating nozzles 9, 10, leftward nozzle 11, front nozzle 12, and rightward nozzle 13).

[0046] When ejecting the fire extinguishing agent (water) by this method, only the fire extinguishing agent may be continuously ejected, or the fire extinguishing agent and the propellant may be alternately switched and ejected in a short time. That is, the propellant may be ejected vertically downward, and the alternating valve 26 (see FIG. 1) may be switched in a short time with the nozzle unit 16 stationary above the fire to intermittently discharge the flow path with water 1 and the propellant (for example, rocket injection gas 4) obliquely downward, that is, toward the fire. Thereby, the mass of water 1 can be flown far by the rocket injection gas 4 to perform the fire extinguishing operation.

[0047] Next, a modified example of the nozzle unit 16 will be described.

[0048] An example of the nozzle section 16 shown in FIG. 3 is the self-propelled ball head 14. The valve nozzles 15 are arranged in a dimpled shape of a golf ball in all directions, and a propellant is jetted from one or a plurality of valve nozzles 15 selectively opened by a built-in switching valve 27 (see FIG. 2), causing the self-propelled ball head 14 to move. Further, a fire extinguishing agent is jetted from one or a plurality of valve nozzles 15 selectively opened by the switching valve 27 to extinguish the fire. Aerial floating fire extinguishing is effective for indoor fire extinguishing. Since the self-propelled ball head 14 is spherical, it can enter narrow places. The fact that the self-propelled ball head 14 has a heat sensor 31 and a control unit 32 is common to the above-described T-shaped self-propelled head 19 (see FIG. 2).

[0049] <Modification example of the object to be conveyed> In the conventional fire extinguishing by an aircraft, there was a drawback that when water was dropped from a high altitude, it atomized and the fire extinguishing effect could not be sufficiently obtained. On the other hand, when the water tank was dropped as a whole onto the fire site, water could not be sprayed over a wide area, and the fire extinguishing effect could not be sufficiently obtained either.

[0050] Therefore, as a first modification example of the object to be conveyed, as shown in FIG. 23, dropping a fire extinguishing agent (water) in small portions into a large number of containers onto the fire site will be described. That is, the fire extinguishing agent container included in the object to be conveyed (fire extinguishing unit 53) according to this modification example includes a plurality of individual containers 114 in which the fire extinguishing agent is individually stored, and an outer packaging member 115 that surrounds these plurality of individual containers 114. Further, such a fire extinguishing agent container includes a receiving means (antenna 116) capable of receiving a trigger signal, and a releasing means (pyrotechnic device 117) that opens the outer packaging member 115 and releases the individual containers 114 from the outer packaging member 115 when the receiving means (antenna 116) receives the trigger signal. The individual container 114 is a capsule made of a resin material. When it is dropped from an airplane at a predetermined altitude and falls to the ground surface, it ruptures due to the falling impact, and the internal fire extinguishing agent (water) scatters around. In addition, the individual container 114 may be made of a water-absorbing polymer material. The outer packaging member 115 may be formed in a shell shape using a hard resin material, or may be formed in a film shape or a net shape using a soft resin material. It is preferable that the individual container 114 and the outer packaging member 115 are made of a biodegradable resin material. This makes it less likely to cause an environmental burden because even if it remains unburned in a fire, it will decompose on the ground. The kite 76 and the pickup cable 74 (not shown) described in the embodiment are attached to the outer packaging member 115, and it is possible to be hooked and connected by a catching part (detachable hook 72) of an airplane (jet plane 98).

[0051] The trigger signal received by the antenna 116 may be transmitted from the control unit 32 (see FIG. 2) of the nozzle unit 16. In this case, when the heat sensor 31 of the nozzle unit 16 detects the heat on the ground in the sky above the fire site, the control unit 32 may transmit a trigger signal to the antenna 116. Alternatively, the pilot may operate the communication means of the airplane (jet plane 98) to confirm that the fire extinguishing unit 53 has dropped to an appropriate height above the fire site and transmit a trigger signal toward the antenna 116. The pyrotechnic device 117 includes gunpowder and an ignition device. Based on the antenna 116 receiving the trigger signal, the ignition device ignites the gunpowder, and the pyrotechnic device 117 explodes to open at least a part of the outer packaging member 115. As a result, the individual containers 114 scattered from the outer packaging member 115 widely fall to the fire site and rupture on the ground, spraying water over a wide area. As the releasing means for opening the outer packaging member 115, in addition to the explosion by the pyrotechnic device 117 exemplified above, various modes such as cutting the outer packaging member 115 with a blade or releasing the locking means can be adopted.

[0052] As a further modification of this modification example, the outer packaging member 115 may be configured to wrap a large number of individual containers 114 by tying a sheet-like net body like a fishing net.

[0053] The second modification example of the object to be conveyed shown in FIG. 4 is an explanatory diagram of a self-propelled long-distance high-altitude hose. The fire extinguishing unit 53 of this modification example has a bobbin 17 provided on a trailer 30 which is a gantry having wheels, and is wound around the fire hose 6 while applying internal pressure thereto, and travels by the propulsive force of the jet engine 18. An intercooler for cooling intake air may be provided in the jet engine 18. A water tank 50 and a submersible pump 60 (see FIG. 2), not shown, are mounted on the trailer 30, and the fire hose 6 is connected thereto, and water pressure is applied to the fire hose 6. The nozzle portion 16 includes a T-shaped self-propelled head 19 (see FIG. 2). As described in the embodiment, the nozzles from which the propellant is ejected in the self-propelled head 19 are selectively switched by the switching valve 27, and it can ascend along a high-rise building or self-propel in a direction approaching a mountain fire.

[0054] The fire hose 6 wound around the bobbin 17 is paid out or wound up depending on the elevating movement along a high-rise building or the distance to a mountain fire. A hose guide (not shown) is provided on the bobbin 17, and winding control for winding up or paying out the fire hose 6 around the bobbin 17 is performed. The hose guide linearly operates according to the winding state of the fire hose 6. The clamped drone 20 shown in FIG. 4 will be described later.

[0055] The T-shaped self-propelled head 19 has a plurality of rotating nozzles at the head, switches the nozzles for ejecting the propellant to move, and extinguishes the fire by ejecting the fire extinguishing agent toward the combustion site of the fire.

[0056] The third modification example of the object to be conveyed shown in FIG. 5 is a roller winding control device. The fire hose 6 wound around the bobbin 17 is wound up or paid out by a bobbin winding device according to the situation. The winding and paying out control of the fire hose 6 is executed by a plurality of roller hose guides 21.

[0057] The roller hose guide 21 moves in parallel by a pair of linear bushings 22 so as to be positioned at the end of the coiled fire hose 6 wound around the bobbin 17.

[0058] FIG. 6 is a view of the clamp drone. The clamp drone 20 is a drone (unmanned helicopter) provided with a hook 28 and a clamp 29. The clamp 29 is used for fixing the fire hose 6. The clamp drone 20 is provided with a plurality of hooks 28, and the respective hooks 28 may have different hanging directions.

[0059] As described above, in order to move the self-propelled head 19 up and down, a propellant is jetted toward the ground to obtain a repulsive force in the vertically upward direction component. When the fluid is switched from the propellant (gas) to the fire extinguishing agent (water) by switching the alternating valve 26 at the position where the self-propelled head 19 has risen, a suddenly large gravity is applied to the fire hose 6. For this reason, the floating force of the clamp drone 20 that supports the fire hose 6 by the clamp 29 prevents the fire hose 6 from falling due to its own weight during fire extinguishing. Alternatively, the fire hose 6 may be hooked on a window frame or the like of a building by the hook 28 of the clamp drone 20 to hold the fire hose 6 in the air. As another usage of the clamp drone 20, while placing a water tank 50 (see FIG. 19) or a cargo on a roller conveyor (pre-acceleration device) and allowing it to run up, the pickup cable 74 (the same as above) can be lifted by the clamp drone 20 and hooked by the landing hook 72 (the same as above) of the airplane at an appropriate position.

[0060] FIG. 7 is a fourth modification of the object to be conveyed, and is a view showing the connection structure between the nozzle portion 16 and the folding hose shown in FIG. 2. The folding hose of this modification is mounted on the trailer 30 as shown in FIG. 8. The metal hose body 24a and the metal hose body 24b adjacent to each other are hermetically joined and rotated by the L-shaped pipe 23. Since the metal hose body 24 can be folded by this rotation mechanism, long-distance fire extinguishing is possible by hermetically joining a number of metal hose bodies 24a to 24c with the L-shaped pipe 23 to form a folding structure. The police box 25 has a built-in water tank and a propellant container, and the water (fire extinguishing agent) stored in the water tank or the propellant stored in the propellant container is selectively supplied to the metal hose body 24 by the switching operation of the police box 25. Since the metal hose body 24 is made of metal and has excellent heat resistance, fire extinguishing work can be carried out even in a high-temperature fire.

[0061] Even when jet injection gas 3 or rocket injection gas 4 (see Fig. 1) is injected as the propellant, since these gases become high-temperature, it is preferable to use the metal hose body 24. It is effective to prepare an intercooler for cooling in the middle of the metal hose body 24. In addition to the metal hose body 24, a pipe body may be made of carbon, ceramic carbon composite material, etc. to form a fire extinguishing hose 6. These are heat-resistant materials, and the pipe body can be maintained during a fire, which is appropriate.

[0062] Although the pipe body of the metal hose body 24 itself has a certain weight, since the rocket injection gas 4 has a strong thrust, theoretically it is possible to raise the self-propelled head 19 by more than 1000 m.

[0063] The nozzle part 16 is a variable-direction nozzle including right-side rotating nozzles 7, 8, left-side rotating nozzles 9, 10, left-direction nozzle 11, front nozzle 12, and right-direction nozzle 13. The rocket injection gas 4 is injected from one or more of them to break the window of the building and enter inside, and the police box 25 switches from the rocket injection gas 4 to water 1 to start fire extinguishing. This rocket injection method is also effective for long-distance mountain fires, and the rocket injection can move in the air toward a distant mountain fire by adjusting the direction of the nozzle part 16.

[0064] Fig. 9 is a fifth modification of the object to be conveyed, and is a view showing an infinitely driven fire extinguishing hose. The object to be conveyed in this modification is one in which a fire extinguishing hose 6 is attached to an infinitely driven body 35. A water tank 50 (see Fig. 12) is connected to the fire extinguishing hose 6. The infinitely driven body 35 has a built-in underwater pump 60 (Fig. 12), and sufficient water discharge can be carried out from the nozzle part 16 even when the length of the fire extinguishing hose 6 increases. The left and right infinitely driven units 40 move independently.

[0065] Figure 10 shows a sixth modification example of the object to be conveyed, and is a diagram showing an intermediate endless drive vehicle. The nozzle portion 16 of the intermediate endless drive vehicle has a self-propelled head 19 with a fire hose 6. The self-propelled head 19 has a plurality of nozzles in the radial direction, and by injecting a fire extinguishing agent or a propellant by an internal pump (not shown), it floats up, injects the fire extinguishing agent downward from above the flame, and can also inject it laterally.

[0066] The endless drive vehicle 36 may be driven by a fuel engine, or may also be motor-driven by a power line passing through the fire hose 6. The left and right endless drives 40 can move independently and turn in different directions. It is effective to prepare a plurality of such endless drive vehicles 36 and surround the fire from all sides to extinguish the fire all at once.

[0067] Figure 11 shows a seventh modification example of the object to be conveyed, and is a diagram showing a turret-type endless drive vehicle. In the turret-type endless drive, a fire hose 6 is fixed to a turret 48 and travels by an endless drive 40. By rotating the turret 48, the extending direction of the fire hose 6 can be changed. The endless drive 40 can move the turret-type endless drive vehicle in a direction orthogonal to the hose length of the fire hose 6 and approach the target fire.

[0068] <Modification Example of Pre-Acceleration Device> Next, a modification example of a pre-acceleration device for assisting the object to be conveyed (fire extinguishing unit 53) to run will be described.

[0069] Figure 13 is a diagram showing pinch tire acceleration according to a first modification example of the pre-acceleration device. The conveying system according to the modification example includes acceleration means installed on the ground to accelerate the pre-acceleration device. Specifically, tires 80 are provided on the lower surface of the water tank 50 so that it can travel on the road surface. At the bottom of the water tank 50, parallel rails, i.e., acceleration plates 82, that protrude downward are provided so as to extend along the traveling direction (front-rear direction). On the road surface, power-rotating clamping tires 84 that rotate at high speed around a vertical axis are provided as driving rotors. A large number of power-rotating clamping tires 84 are arranged in two rows on the left and right and are rotationally driven in opposite directions to each other as indicated by the arrows. When the acceleration plate 82 is clamped between a pair of power-rotating clamping tires 84, the acceleration plate 82 is pushed forward by the rotational force. The preliminary acceleration device in this modification example is the acceleration plate 82, and the accelerating means for accelerating it is the power-rotating clamping tire 84.

[0070] The power-rotating clamping tires 84 are initially rotated at a low speed, and as the water tank 50 accelerates, they are rotated at a high speed. Finally, the water tank 50 is accelerated to 300 km / h or more. Fixed parts 83 are provided on the left and right sides of the water tank 50, and a pair of kites 76 are connected to the fixed parts 83 via wires. A pickup cable 74 is suspended between the pair of kites 76. When the jet plane 98 overtakes the water tank 50 that has been accelerated at high speed from behind, the water tank 50 is connected to the jet plane 98 and conveyed by hooking the pickup cable 74 with the detachable hook 72. A drop parachute 52 is provided on the water tank 50. The water tank 50 dropped from the jet plane 98 is decelerated by the kites 76 and the drop parachute 52 catching the wind and is conveyed to the conveyance destination such as the site of a fire.

[0071] FIG. 14 is a diagram of the left and right bobbin cable water tank acceleration according to the second modification example of the preliminary acceleration device. The water tank 50 to be accelerated is installed on a carrier vehicle (not shown) equipped with tires with straight - ahead control. A cable 86 is arranged so as to loop around behind the water tank 50. The bobbins on both front sides, the right - hand bobbin 85a rotates clockwise to wind up the cable 86, and the left - hand bobbin 85b rotates counter - clockwise to wind up the cable 86. Thereby, a driving force in the forward direction is applied to the water tank 50. The left and right bobbins may be driven by a motor or by an internal combustion engine.

[0072] The water tank 50 is launched by the principle of an arrow by the cable 86. When speed is gained, the kite 76 rises and is caught by the pickup cable 74 coming down from the aircraft and rises.

[0073] Figure 15 is an explanatory diagram of straight - ahead control according to a third modification example of the preliminary acceleration device. As straight - ahead control when the water tank 50 accelerates, front wheels supporting the water tank 50 are provided with front forks 90 at the upper part of the tires. The straight - ahead control motor 94 moves the straight - ahead control arm 92 left and right via gears etc. to make it go straight.

[0074] Figure 16 is a diagram showing a method of accelerating a water tank using a high - speed jet plane according to a fourth modification example of the preliminary acceleration device. A cable 49 is attached to the rear part of the jet plane 98a and the water tank 50 is connected. The jet engine of the jet plane 98a is used to accelerate the water tank 50 to nearly 300 km / h.

[0075] As shown in Figure 12, a kite 76 is attached to the water tank 50. When the water tank 50 is accelerated at high speed by the jet plane 98a, the kite 76 rises and is hooked and connected by the detachable hook 72 of another jet plane 98 as shown in Figure 19. Immediately before that, when the water tank 50 is sufficiently accelerated, the cable 49 is cut, and the jet plane 98a flies away at high speed.

[0076] Figure 17 is a diagram showing a rail according to a fifth modification example of the preliminary acceleration device. Place the freight car 100 on the rail 105, load the water tank 50, and accelerate it with the jet engine 102 or the Shinkansen carriage. At high speed, the kite 76 of the water tank 50 rises and is caught by the landing hook 72 of the airplane (see Fig. 19) and rises.

[0077] Fig. 18 is a diagram showing a straight-ahead vehicle using a laser light source according to a sixth modification of the preliminary acceleration device. Install a laser light source 95 as a travel target on a flat and well-maintained place such as an airport. A jet engine 102 or a rocket engine is installed on a carrier 110 with tires 109, and a water tank 50 is placed on the carrier 110. The steering device of the carrier 110 controls the traveling direction of the carrier 110 with a stepping motor targeting the position of the laser light source 95. After picking up the kite 76 with an airplane and transferring the water tank 50 from the carrier 110 to the airplane, stop the carrier 110 with a brake.

[0078] Fig. 20 is a diagram showing a pickup using a tower according to a seventh modification of the preliminary acceleration device. In this modification, potential energy is used as an accelerating means for accelerating the preliminary acceleration device. The fire extinguishing unit 53, which is the object to be conveyed, has a water tank 50 and is placed on a carrier 110, which is a preliminary acceleration device. Then, when the water tank 50 slides down the downward slope 123 from the top 125 of the tower 120 for acceleration, the kite 76 rises. The water tank 50 continues to slide down, and when it reaches the maximum speed near the ground and leaves the tower 120, the kite 76 is hooked on the landing hook 72 of the airplane (see Fig. 19). According to this method, contact troubles between the landing hook 72 and the tower 120 can be avoided.
