Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating fish reef system used as an ocean ranch installed in the sea, and is particularly devised to facilitate maintenance and management of floating fish reefs.

[0002]

2. Description of the Related Art In recent years, floating fish reefs have been moored in the sea,
Realization of a marine ranch is being carried out. Floating reef
It is installed in the sea several tens of meters below the sea level, and is anchored by a wire to the weight, anchor, etc. on the sea floor. In addition, a buoy is floated from the floating reef to the surface of the sea via a wire to indicate its position. Here, the floating fish reef is inspected and maintained, but since it is not possible to work in the sea,
It is performed by levitating above the sea. In order to carry out maintenance inspections and maintenance of floating fish reefs, first, while operating a work boat at sea, look for buoys and confirm the position of floating fish reefs. Next, the tethered wire is cut, and the floating fish reef is raised.
Next, after carrying out maintenance inspections and maintenance of the floating fish reef, it is again pulled into the sea by a tether wire and submerged.

[0003]

[Problems to be solved by the invention] Maintenance inspection of floating fish reef
The above-mentioned work is required for maintenance, which requires a great deal of time, labor and cost. There are also the following problems.

Since the buoy is constantly levitated from the floating fish reef via the wire, the wire hinders navigation of the ship. If a buoy leaks out or a floating fish reef moves to a deep place due to ocean currents, etc., the buoy will not be visible, making search difficult and hindering the navigation of the ship. When floating floating reefs are raised to the surface of the sea during maintenance and inspection, the wires, weights, anchors, etc. are discarded to cut off the wires, resulting in wasted costs and environmental pollution. It takes too much time and money to dive a diver up to tens of meters under the sea for cutting wires. Furthermore, after maintenance and inspection, when it settles down and is fixed again, new wires, weights and anchors are required, which takes time and cost.

The present invention has been made to cope with the above situation, and an object of the present invention is to provide a floating fish reef management system capable of facilitating maintenance inspection / maintenance of floating fish reefs.

[0006]

According to the present invention, there is provided a floating fish reef body, which is anchored in the sea through a wire at a mounting portion on the seabed, and a floating buoy at the tip of which a power connector is attached. It is attached to a power cable that it has, and is attached to the floating fish reef main body and a power cable control device with a remote control function that can unwind and wind the power cable, and can unwind and wind the wire. And a mooring control device capable of floating the floating fish reef body from the sea surface to the sea surface or sinking from the sea surface to the sea surface, and remote control means for remotely controlling the operation of the mooring control device. It is a thing.

[0007]

With the above means, the power cable control device is first remotely controlled to levitate the power cable and supply power to the tether control device, thereby
By remote control, it can float from the sea and sink from the sea surface.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. 100
Is a work boat, and 200 is a floating fish reef body in a state of sinking to a certain depth (for example, several tens of meters) in the sea. The work boat 100 is provided with an ultrasonic direction finding receiver 101, which can receive an ultrasonic wave from an ultrasonic oscillator 201 provided in the floating fish reef main body 200 to confirm the existing position of the floating fish reef main body 200. It is like this. The ultrasonic oscillator 201 is operated by a battery 202 mounted on the floating fish reef body 200. According to the ultrasonic detection system, it can be confirmed within a distance of about 2 km even in a dark night or a thick fog regardless of weather conditions and time. Therefore, the setting position of the floating fish reef main body 200 is once written in the nautical chart at the time of setting, and the work boat is moved to the vicinity thereof.

The work boat 100 includes an underwater communication radio transmitter 1
02 is installed. When a command signal is transmitted from the underwater communication wireless transmitter 102, the command signal is received by the underwater communication wireless command receiver 203 mounted on the floating fish reef main body 200.
This communication system is a system for controlling the power cable control device 204 and the mooring control device 220 mounted on the floating fish reef body 200. When the underwater communication wireless command receiver 203 receives the power cable levitating command signal for levitating the levitating buoy 205, the power cable control device 204
The floating buoy 205 is unlocked and the power connector 206
The power cable 207 having the above is released, and thereby the power cable 207 is levitated to the sea surface.

When the power cable 207 floats above the sea surface,
The work boat 100 picks up the power cable 207, connects the power connector 206 to the power equipment of the work boat, and the preparation is completed. In the work boat 100, after the preparation is completed, the underwater communication wireless transmitter 102 sends a fish reef floating command signal of the floating fish reef main body 200. Then, supply of large electric power to the mooring control device 220 mounted on the floating fish reef main body 200 is started. Further, the mooring control device 220 unlocks the wire, controls the rotation of the motor, and operates in a direction to unwind the mooring wire 221 that moor the floating fish reef body 200.
Further, the battery 202 is also charged by this power source.

The other end of the tether wire 221 is attached to the weight / anchor 300 hanging on the seabed, and the floating fish reef body 2 is attached.
00 is moored. Therefore, when the mooring wire 221 is unwound, the floating fish reef body 200 floats above the sea surface due to its buoyancy.

The floating fish reef main body 200 that has floated to the surface of the sea is subjected to maintenance and inspection, battery check, and other management. When the work is completed, the work boat 1
00, the underwater communication wireless transmitter 102 sends a fish reef sinking command signal. Then, the anchor wire 221 is wound up this time. As a result, the floating fish reef body 200 is settled down to several tens of meters below the sea level. The motor is stopped and the power supply is stopped when the water is settled to a desired depth. Also, the wire lock is activated.
This lock operation signal is transmitted by the ultrasonic wave transmitter 201. The work boat 100 can confirm that the floating fish reef main body 200 is fixed at a fixed position by receiving the lock operation signal. The sinking depth of the fish reef can be known, for example, from the winding amount of the tether wire 221, and can be set by designating the winding time in advance.

In the work boat 100, when it is confirmed that the floating reef main body 200 is fixed, the power connector 206 connected to the power equipment of the work boat 100 is detached and waterproofed, and the floating buoy 205 and the sea surface are attached. Be taken down by. Next, the underwater communication wireless transmitter 102 sends a floating buoy sinking command signal to the underwater communication wireless command receiver 203. Then, the power cable control device 204 is controlled, the motor is rotated, the power cable 207 is wound, and the floating buoy 2
Along with 05, it was made to sink to the floating fish reef main body 200 side,
The motor is stopped at a predetermined position. And the buoy buoy 205
Is locked and the work is completed. The lock completion signal of the buoy buoy 205 is transmitted from the ultrasonic transmitter 201 and is confirmed by the work boat side. At this time, the electric power is the battery 20.
Will be covered by 2.

According to the system described above, the floating fish reef main body 200 has an ultrasonic transmitter for displaying the position, and constantly oscillates data such as the unique number of the floating fish reef.
Therefore, the position can be easily confirmed by the work boat regardless of time and weather conditions. Further, unlike the conventional case, a position display buoy that is always floating on the sea surface is not necessary, and it does not hinder the navigation of the ship. Since it has an underwater communication wireless command receiver for levitating orders, it is designed to operate the wire mooring motor to levitate fish reefs at the command of the work boat.
As in the past, there is no need for a wire cutting diver, which saves a lot of time and money. Furthermore, re-settling and fixing after maintenance and inspection are performed by operating the wire mooring motor in response to the underwater communication command sent from the work boat, so new wires, weights and anchors are not required, saving costs and preventing environmental pollution. Will be effective. The power source of the floating reef is a small battery that operates only the ultrasonic transmitter and underwater communication receiver, etc., because the power cable is first levitated and supplied from the work boat through this power cable. .

Next, a method of waterproofing the wire 221 mounting portion in the floating fish reef described above will be described. As shown in FIG. 2, the exposed portion of the tether wire 221 is the dome portion 2 provided on the lower surface of the bottom plate 231 of the floating fish reef main body 200.
0a. When the floating fish reef main body 200 is submerged, air accumulates in the dome portion 20a. A motor 22a for winding and unwinding the wire 211 is installed in the space where the air is collected. As a result, the motor 22a and the shaft 22b can be blocked from the seawater.

[0017]
