The altitude sensor 8 in FIG. 1 includes a two-core conductor 48 electrically connected to the rocket ignition device 7, an electrode switch 49 connected to the lower end of the two-core conductor 48, and an upper part of the electrode switch 49. And a weight 50 that is attached to suspend the conductor 48. The electrode switch 49 conducts when it comes into contact with the sea surface, closes an ignition circuit formed by the two-core conductive wire 48 and a circuit in the rocket ignition device 7, and causes the rocket ignition device 7 to perform ignition operation. In the altitude sensor 8 having such a configuration, the drooping length of the conducting wire 48 determines the altitude at which the rocket 6 is ignited. The altitude sensor 8 is appropriately set according to the mass of the entire rescue device, the descent speed of the parachute 1 and the like. Is set.
[0022]
Next, the operation of the aircraft drop-type indirect rescue apparatus having the above configuration will be described.
First, as shown in FIG. 8, when the entire rescue device is dropped from the aircraft 60 in the vicinity of the maritime victim A, the setting of the parachute 1 itself is performed in a state where the guided rescue device 4 is suspended below the parachute 1. Descent at speed. When the electrode switch 49 in the altitude sensor 8 comes into contact with the sea surface after descending to near the sea surface, the ignition circuit is closed and the rocket igniter 7 is activated, and the ignition signal is transmitted to the ignition part of the rocket 6. The rocket 6 is injected.
[0023]
Since the descent speed is decelerated by the injection of the rocket 6, the entire apparatus reaches the sea surface at a low speed, and the impact acting on the rescue apparatus 4 is sufficiently mitigated. At the time of landing, a reaction force acts on the rescue device 4 from the sea surface. By using this reaction force, the rescue device holding mechanism 5 of FIG. 1 is detached as described above, so that the rescue device 4 is automatically disconnected from the parachute 1 and the drop device main body 3.
[0024]
When the rescue device 4 is disconnected from the parachute 1 and the dropping device main body 3, the rocket 6 is still in an operating state. Therefore, the load of the rescue device 4 is released and the parachute 1 and the dropping device main body 3 lightened. The rocket 6 is launched upward by receiving the propulsive force of the rocket 6 and is separated far away. Thereby, the tangle between the parachute 1 and the rescue device is prevented. On the other hand, the separated rescue device 4 floats on the sea.
[0025]
Thus, the rescue apparatus 4 that has levitated to the sea receives the radio signal from the aircraft 60 by the radio transceiver 13 through the antenna 19. First, the linear actuator 30 in the lifting mechanism 12 is moved through the propulsion unit controller 14. Stretch operation. As the linear actuator 30 extends, the bendable link 31 is bent as shown by the phantom line in FIG. 5, and the rotary shaft 22 is rotated around its axis. As a result, the propulsion unit 11 is displaced in the direction of the arrow X in FIG. 5, protrudes to the lower part of the propulsion unit storage chamber 10, and develops on both the left and right sides. At this time, the lower door 26 of the propulsion unit storage chamber 10 opens downward in conjunction with the displacement of the propulsion unit 11 via the support arm 11a and the link 28. On the other hand, the upper door 24 is pushed out by the propulsion device 11 against the urging force of the spring 27 and opened outward, and when the propulsion device 11 protrudes outside, the upper door 24 is returned to its original position by the elastic force of the spring 27. Automatically recovers.
[0026]
In this way, the propulsion device 11 is deployed outside after the rescue device 4 floats on the sea, and is stored inside the rescue device 4 at the time of landing, so there is no possibility of being damaged by an impact at the time of landing.
[0027]
Next, a radio signal is sent from the aircraft 60 side while looking at the radar scope 61 installed in the aircraft 60 of FIG. 8 and displaying the position of the victim A, the falling position of the rescue device 4 and the wind direction, etc. By controlling the rotation (forward rotation, reverse rotation, rotation speed, etc.) of the propulsion device 11 via the propulsion device control unit 14, the rescue device 4 is brought closer to the victim A.
[0028]
When the rescue device 4 approaches the distress A and sends instructions by radio from the aircraft 60 side, the instructions are received by the wireless transceiver 13 in FIG. It is transmitted to the victim A. In addition, the words of the distress A and the like are transmitted to the aircraft 60 side of FIG. 8 through the transmitter / receiver 20 so that the situation of the distress A can be grasped on the aircraft 60 side.
[0029]
Next, when a life buoy leaving command signal is sent from the aircraft 60, the rotary actuator 39 in the detaching device 15 in FIG. 4 is rotated, and each of the rotation actuators 39 via the links 40, 41, the rod 42, the branch plate 36 and the rod 38 in FIG. As shown by the phantom line in FIG. 6, the hook 35 rotates to a position where it is detached from the holding metal fitting 33. Thereby, the said cylindrical storage case 17 will detach | leave from the conveyance body 9, and will be in a free state. Thereby, the front opening 17a of the storage case 17 of FIG. 4 is opened, and the lifebuoy 16 can jump out.
[0030]
At this time, in conjunction with the rotation of the branch plate 36, that is, in conjunction with the detaching operation of the detaching device 15, the operating cord 46 of FIG. 7 is pulled to open the air cylinder 43, and accordingly, the air cylinder 43 is opened. High-pressure air is jetted into the life buoy 16 from 43, and the life buoy 16 is rapidly expanded and expanded as shown in FIG. Victim A gets into the inflated lifeboat 16 and waits for rescue.
[0031]
In addition, although the said Example demonstrated what rescued the apparatus near the victim using the aircraft 60, you may drop from a ship. In that case, the parachute 1 or the rocket 6 is not required. In the type of dropping from a ship, a wired remote operation can be used instead of the wireless remote operation as in the above embodiment.
[0034]
【The invention's effect】
As described above, according to the invention of claim 1, the propulsion unit is deployed outside the conveyance unit by remote operation in a state where the dropped conveyance unit floats on the water, and the propulsion unit is propelled by remote operation. It is possible to control, and the entire rescue device can be quickly brought close to the victim. Moreover, the rescue kit can be taken out of the transport body by remote control when reaching the vicinity of the victim and the rescue for the victim can be executed. Therefore, even if the dropping position on the water is slightly shifted, the rescue kit should be approached quickly and reliably to the victims regardless of the wind strength or direction, and the reliability of the rescue operation should be significantly increased. Can do. In addition, the life buoy can be rapidly inflated by the high-pressure gas ejected from the gas cylinder in conjunction with the detachment operation of the storage case from the carrier, so that the victim can be rescued reliably.
[0036]
According to the invention of claim 2 , when the rescue device is dropped from the aircraft, the descent speed is reduced to reduce the impact at the time of landing and prevent the propulsion unit and the rescue kit from being damaged or destroyed. Thus, a predetermined rescue function can be surely exhibited.
