  However, in the invention described in Patent Document 1, the mooring rope 33 is divided by the cutting device 45 attached to the mooring rope 33 after the underwater measurement is finished, and floats on the water surface by the buoyancy of the buoyancy bodies 13 and 40. Only the underwater observation device 41 and the lifting device 1 are collected, and the dividing device 45, the weight 46, and the mooring rope 33 that connects the dividing device 45 and the weight 46 remain on the bottom of the water, and the lifting device 1 is recovered. There was a problem that could not be.

  Further, in the invention relating to the underwater vehicle A equipped with the equipment necessary for the investigation or observation described in Patent Document 2, the main body 1 of the underwater vehicle A after completion of various underwater investigations or observations. The buoy 30 is released from the rope 31 connecting the main body 1 and the buoy 30, and a four-forked hook 53 attached to the tip of the rope 54 is placed by the operator's hand placed on the mother ship B.

In the present embodiment, the crane 3 is installed on the mother ship 2, but the present invention is not limited to this. For example, when the underwater observation device 10 is collected near the land, the crane 3 is collected on the land. It can also be done.

As shown in at least one of FIGS. 1 to 3, the underwater observation device 10 includes a (small) communication buoy 13, an underwater observation device main body 11, an underwater observation device 10, as shown in at least one of FIGS. 1 to 3. The observation device collection device 12 is combined.
The communication buoy 13 includes an antenna 21, a satellite communication device 22, a controller 23, a communication means having an optical communication device (optical communication modem: communication device) 27, a secondary battery 24, a recording device 25, and the like. The non-contact charger 26, the buoyancy body 28, and the pressure resistant shell 29 are provided.
In addition to the communication buoy 13, the underwater observation equipment collection device 12 includes a non-contact charger 31, an optical communication device (communication device) 34, a reel 35, a storage cylinder 37, and a housing 38.
The underwater observation device main body 11 includes a battery 32, a controller 33, a recorder 36, and various sensors A, B.
In the present embodiment, an optical communication device is applied as a communication device provided in the communication buoy 13 and the underwater observation equipment collection device 12, but the present invention is not limited to this, and a wireless communication device or an infrared communication device is used. Etc. are also possible.

The buoyancy body 28 is formed by forming a buoyancy material such as a syntactic foam into a hydrodynamic shape, and an antenna 21 is attached to the top of the buoyancy body 28.
The pressure-resistant shell 29 is a pressure-resistant containment vessel (pressure vessel), which includes a satellite communication device 22, a controller 23, a secondary battery 24, a recorder 25, and a light / signal converter (not shown). A levitation detector such as a pressure gauge and an accelerometer is housed.
The outer shape of the communication buoy 13 is formed by the outer shape of the buoyancy body 28 and the outer shape of the pressure-resistant shell 29.

The storage cylinder 37 is a cylindrical member that accommodates the communication buoy 13 therein, and a guide 39 that guides the communication buoy 13 into the accommodation cylinder 37 when the communication buoy 13 is accommodated is provided at the top. The non-contact charger 26 of the communication buoy 13 is guided to the non-contact charger 31 provided at the lower end of the housing cylinder 37 when the communication buoy 13 is accommodated at the lower end portion in the interior thereof. A seat 40 on which the lower surface (bottom surface) of the communication buoy 13 is seated is provided while the communication devices 27 and 34 are guided closer to each other.
The casing 38 accommodates a reel 35 and a motor / tensioner 44.

A cable 41 made of Kevlar, carbon fiber, or the like is wound around the reel 35 for a predetermined length. One end of the cable 41 is fixed to the swivel 42, and the other end of the cable 41 is fixed to the reel 35.
In addition, when the communication buoy 13 floats on the sea surface (water surface) 51, and the communication buoy 13 transmits data to the communication satellite 43, an aircraft (not shown), a ship, etc. on the water surface 51, the communication satellite 43 or an aircraft (not shown), When receiving data transmitted from a ship or the like, the tension received from the ocean current (water current) or the like so that the cable 41 does not get entangled or the buoyancy of the communication buoy 13 exceeds the allowable strength of the cable 41 The reel 35 is rotated so as not to be applied, and the cable 41 can be fed out with free or moderate tension. Here, the allowable strength of the cable 41 is a value that is sufficiently smaller than the buoyancy of the communication buoy 13 and that the cable does not loosen. The cable 41 is a thin wire with a diameter of several millimeters (for example, about 1 mm) not accompanied by a power line. By using such a thin wire, even if twisting occurs, the cable 41 is more tolerable than the power line. Underwater resistance can be reduced, and a large tension does not act on the communication buoy 13 via the cable 41. As a result, the communication buoy 13 can be reduced in size.

Reference numeral 44 in FIGS. 1 and 2 denotes a motor / tensioner that rotates the reel 35 (with a tachometer or a ratchet), and can appropriately control the motor rotation speed while measuring the tension of the cable 41. .
Furthermore, a restraining mechanism 46 that is opened and closed (on / off) by a drive mechanism 45 is provided at the upper end portion of the storage cylinder 37 located on the guide 39 side.
Furthermore, the underwater observation apparatus 10 is provided with a receiver (not shown) that receives an acoustic command (acoustic signal) sent from the mother ship 2, and the receiver receives an acoustic signal sent from the mother ship 2. When a command (acoustic signal) is received, a command (signal) for raising the communication buoy 13 to the sea surface 51 is sent (output) from the receiver to the controller 33, and the communication buoy 13 rises to the sea surface 51. ing. Further, the reel 35 can be rotated to wind the cable 41.

  Now, in the underwater observation equipment collection device 12 according to the present embodiment, the underwater observation equipment main body 11 is accommodated in the state shown in FIGS. 1 and 3, that is, in the state where the communication buoy 13 is accommodated in the accommodation cylinder 37. An optical communication device 27 that is charged from the battery 32 to the secondary battery 24 accommodated in the pressure-resistant shell 29 via the non-contact chargers 26 and 31 and attached to the lower end of the communication buoy 13; Data exchange (communication) is performed with the optical communication device 34 provided at the lower end of the housing cylinder 37. In addition, as the battery 32, a primary battery, a secondary battery, a fuel cell etc. are used, for example.

Next, when a predetermined amount of data collected by the underwater observation equipment main body 11 installed on the seabed 52 is accumulated, the communication buoy 13 is started to float as shown in FIG.
Subsequently, as shown in FIG. 5, when the communication buoy 13 emerges on the sea surface 51, communication with the communication satellite 43, an aircraft (not shown), a ship, and the like is started.

Next, as shown in FIG. 6, when communication with the communication satellite 43, an aircraft (not shown), a ship, or the like is completed, or the cable 41 is fully extended (extends), tension (tension) is applied to the cable 41. When this happens (begins to join), the motor / tensioner 44 (see FIGS. 1 and 2) is rotated in the reverse direction, and the communication buoy 13 is recovered as shown in FIG.
Further, when the communication buoy 13 ascends to the sea surface 51, since the levitation stops, the tension is expected to change greatly. Therefore, the measurement is performed by the motor / tensioner 44, and the ascent timing and the communication buoy 13 are measured. The floating time may be set, and when the set time is reached, the reel may be driven to collect the communication buoy 13.

  When the communication buoy 13 rises on the sea surface 51 and communicates with the communication satellite 43, an aircraft (not shown), a ship, etc. on the sea surface 51, the motor / tensioner 44 is connected to the communication buoy 13 as shown in FIG. The buoyancy center and the center of gravity of the communication buoy 13 are (almost) kept on the same vertical line, and the cable 41 is in accordance with the tension received from disturbance such as ocean current so that the cable 41 does not get entangled. In addition, the cable is fed out so that the communication buoy 13 can be rotated so that a tension greater than the buoyancy of the communication buoy 13 is not applied.

Next, a method for recovering the underwater observation device 10 laid on the seabed 52 using the underwater observation device recovery apparatus 12 according to the present embodiment will be described with reference to FIGS. 9 to 14.
First, as indicated by (1) in FIG. 9, communication is performed from the mother ship 2 toward the underwater observation device 10 (more specifically, an acoustic signal receiver (not shown) provided in the underwater observation device 10). An acoustic command for causing the buoy 13 to float on the sea surface 51 is transmitted. Then, a command to lift the communication buoy 13 to the sea surface 51 is sent from the receiver of the underwater observation device 10 that has received the acoustic command to lift the communication buoy 13 to the sea surface 51, and the motor / tensioner from the controller 33. 44, a command to raise the communication buoy 13 to the sea surface 51 is sent, and the cable 41 wound around the reel 35 is fed out, and the communication buoy 13 starts to rise as shown by (2) in FIG. .

Next, as shown by (3) in FIG. 10, when the communication buoy 13 rises to the sea surface 51, information (data) on the position coordinates measured by the communication buoy 13 with GPS is sent to the mother ship 2 via the communication satellite 43. Sent.
Subsequently, as indicated by (4) in FIG. 10, in the mother ship 2, the position of the communication buoy 13 is confirmed (specified) based on the information regarding the position coordinates of the communication buoy 13 sent from the communication satellite 43, The mother ship 2 is directed to the sea area where the communication buoy 13 exists, and the communication buoy 13 is collected on the deck of the mother ship 2.
Since the communication buoy 13 is small and light, even when the waves are severe, the cable 41 and the communication buoy are hooked on the cable 41 by, for example, a hook provided at the tip of the boat hook and the operator on the deck. The communication buoy 13 can be easily collected by pulling 13 without difficulty.

Next, the communication buoy 13 attached to the tip of the cable 41 is removed, and the cable attached to the tip of the high-strength cable 4 wound around the drum constituting the crane 3 as shown by (5) in FIG. A connecting tool (coupling) 47 is attached to the tip of the cable 41, and the cable 41 and the high-strength cable 4 are connected via the cable connecting tool 47.
At this time, it is preferable that the communication buoy 13 and the cable 41 are employed as a mechanism that can be easily attached and detached with a hook (not shown) having a swivel function. On the other hand, it is more preferable to attach a hook (not shown) that can be connected to the hook of the cable 41 to the high-strength cable 4.
The high-strength cable 4 is, for example, a cable made of Kevlar having a diameter of about 1 cm (such as a Kevlar cable), and can lift a heavy object of 1 to 20 tons, and has a higher tensile strength (allowable) than the cable 41. Tensile strength). In addition, as long as a high intensity | strength cable is a cable which has the intensity | strength which can pull up the underwater observation apparatus 10, a material and a cable structure may be used.

  In the present embodiment, the communication buoy 13 is removed and the cable connector 47 is separately attached. However, the present invention is not limited to this, and for example, the communication buoy 13 also serves as the cable connector 47. In this way, the high-strength cable 4 and the communication buoy 13 may be directly connected via a connection tool such as a swivel provided at the upper end of the communication buoy 13. Since the communication buoy 13 also serves as the cable connector 47 in this way, it is not necessary to remove the communication buoy 13 and attach the cable connector 47 instead. The number of man-hours can be reduced, and the underwater observation device 10 can be collected more efficiently.

  Subsequently, an acoustic command for winding the cable 41 around the reel 35 is transmitted from the mother ship 2 toward the underwater observation device 10 (more specifically, an acoustic signal receiver provided in the underwater observation device 10). Then, a command for winding the cable 41 on the reel 35 is sent from the receiver of the underwater observation device 10 that has received the acoustic command for winding the cable 41 to the reel 35, and the motor / tensioner is sent from the controller 33 to the reel 35. A command for winding the cable 41 around the reel 35 is sent to 44, and the cable 41 is wound around the reel 35 as indicated by (6) in FIG.

  Next, as shown in FIG. 14, when the winding of the cable 41 onto the reel 35 is completed, a command for closing the restraining mechanism 46 is sent from the controller 33 to the drive mechanism 45, and the restraining mechanism 46 is closed. As shown by (7) in FIG. 12, the cable connector 47 attached to the tip of the high-strength cable 4 does not come out from the housing cylinder 37 of the underwater observation equipment collecting device 12. The cable 4 (more specifically, the cable connector 47) is fixed (connected) to the underwater observation device 10.

Subsequently, as shown by (8) in FIG. 13, the drum constituting the crane 3 is rotated to wind up the high-strength cable 4, and the underwater observation device 10 is collected on the deck of the mother ship 2.
In addition, the underwater observation device 10 can be laid on the seabed (water bottom) 52 by following the procedure opposite to the procedure described above.

According to the method for collecting the underwater observation device 10 according to the present embodiment, the communication buoy 13 is levitated on the sea surface 51, and the communication buoy 13 levitated on the sea surface 51 is collected on the deck of the mother ship 2 and installed on the deck. The cable connecting tool 47 attached to the tip of the high-strength cable 4 wound around the drum constituting the crane 3 is connected to the tip of the cable 41, and the cable 41 is wound around the reel 35, and the inside of the storage cylinder 37 After the cable connector 47 is restrained by the underwater observation device collection device 12 so that the cable connector 47 accommodated in the tube does not come out of the storage cylinder 37, the drum is rotated to wind up the high-strength cable 4, and underwater observation The device 10 is collected on the deck.
Thereby, all of the underwater observation devices 10 can be safely recovered without throwing the diver into the water.

It is more preferable that the battery charger 64 is provided with an electric wire 65 that supplies electric power from the mother ship 2 to the contactless charger 64 instead of the high-strength cable 4. That is, it is built in the underwater observation equipment (more specifically, the underwater observation equipment incorporating the underwater observation equipment collection device 61) from the mother ship 2 through the electric wire 65, the noncontact charger 62, and the noncontact charger 64. More preferably, the battery 32 (see FIG. 3) can be charged.
As a result, the underwater observation device can be charged without collecting the underwater observation device, the operation time of the underwater observation device can be extended, and the running cost can be reduced.
