Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recovery type sonar device, and more particularly to a recovery type sonar device which enables separation and operation of a sensor unit from a helicopter.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional recovery sonar device for a helicopter includes a control recorder 16 for detecting, controlling, instructing, displaying, and recording, and a hoist 17 for hoisting and lowering a cable 18. And a wave transmitter / receiver 19 which is connected to the cable and transmits / receives an acoustic signal.

When operating a conventional helicopter hoisting and sonar system, the helicopter is flown to a desired point, hovering there, suspending the transducer in the sea to collect detection information, and then The operation was ended by collecting the transducers.

[0004]

With this conventional helicopter sonar device, the helicopter must hover at that point during operation, not only during detection information collection but also during suspension collection of the transducer. Since the sonar device must be operated, it is difficult to move while the sonar device is in operation, which makes it vulnerable to attack. Further, since the sonar device is fixed to the body of the helicopter, there is a problem that a single machine can only collect detection information at one point at a time.

[0005]

An object of the present invention is to improve the inconvenience of the conventional example, and particularly, to obtain the sonar detection information simultaneously over a wide area at a plurality of locations, and at the same time, to recover the buoyancy body to another deployment location. The sole purpose is to provide a sonar device.

[0006]

SUMMARY OF THE INVENTION In the present invention, a buoy body equipped with a floating side transmitter for outputting a detected signal and sonar detection information to a flying body for detection, and a buoy body via a cable. It is equipped with a suspended sonar transducer and a controller that is installed in this buoyancy body and sends the detection information collected by the sonar transducer to the floating side transmitter. The structure is such that it has a combined structure. This is intended to achieve the above-mentioned object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The embodiment shown in FIGS. 1 to 6 is a buoy body 12 equipped with a floating side transmitter 8 that outputs a detected signal and sonar detection information to an aircraft for detection such as a helicopter, and the buoy body 12 Cable 13
The sonar transmitter / receiver 14 suspended via the controller 1 and the controller 1 that is installed in the buoyant body 12 and sends the detection information collected by the sonar transmitter / receiver 14 to the floating side transmitter 8.
It has 0 and. Further, the buoyant body 12 is provided with an engaging structure that functions at the time of recovery. On the other hand, the flying body 7 such as a hexcopter is equipped with a recovery mechanism 50 for recovering the buoyant body 12, a receiver 3 for receiving and recording a detected signal and sonar detection information from the buoyant body 12, and a control recorder 1. ing. This will be described in more detail with reference to FIGS. 1 to 6 above.

[0008]

EXAMPLE In the example, a helicopter unit 7 for transmitting / receiving, controlling, and recording signals between the buoy portion 12, a cable 13 suspended in the sea, a transducer 14 connected by the cable 13, and the buoy portion 12. Composed of and.

According to the instruction from the control recorder 1, the submarine portion 15 is suspended at a desired depth from the buoyant portion 12 dropped on the sea.
Collect detection information. The detection information collected from the transducer 14 on the buoy portion is transmitted to the receiver 3 on the helicopter side using the transmitter 9 on the buoy portion. The detection information received by the receiver 3 on the helicopter side is sent to the control recorder 1 and used for detection. After the completion of the detection information collection, a hoisting instruction from the control recorder 1 is sent to the controller 10 through the transmitter 2 and the receiver 9, and the hoisting device 11 hoists the undersea portion 15.

FIG. 3 is an external view of another embodiment of the present invention. The embodiment shown in FIG. 3 shows the state of the recovery work of the buoy portion 12, and the underwater portion 15, the buoy portion 12 wound up inside the buoy portion, and the central portion of the hinge portion under the control of the control recorder 1. A collector 6 that fixes and collects the narrowed part in the center of the buoyant part 12 by sandwiching it by opening and closing the number.
It has a cable 5 which is used to wind the recovery device 6 inside the helicopter.

In accordance with an instruction from the control recorder 1, the cable 5 is hung from the winder, and the collector 6 opened below 180 degrees is floated on the sea and towed at a slow speed (FIG. 5). By opening the collector 6 and pulling it, the frontage for receiving the buoy portion 12 becomes wider, and when the buoy portion 12 reaches the engraved part of the recess for holding the collector 6, the control recorder 1 The collector 6 is closed according to the instruction, whereby the collector 6 sandwiches and fixes the buoy portion 12 (FIG. 6). After that, the cable 5 is wound up by a winder to be collected inside the helicopter.

[0012]

As described above, according to the present invention, by using the buoy portion for suspending and collecting the undersea portion and the helicopter portion having the collector for collecting the buoy portion, the sonar device can be separated and operated. It enables easy recovery, enables operation of multiple suspended sonar sensors in a single helicopter, and eliminates the need for hovering during operation, significantly expanding the area that can be handled by a single helicopter. It is possible to provide a superior fixed-type sonar device that is not possible in the conventional example.
