DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a middle-layer floating reef which is moored in a floating state in a middle part of the sea via a mooring line at an anchor portion submerged on the sea floor, and which drifts due to breakage of the mooring line. A middle floating fish reef that issues a warning.

[0002]

2. Description of the Related Art Conventionally, for a reef floating on a sea surface, which is moored on a sea surface via a mooring line at an anchor portion sunk on the sea floor, a radio wave transmitter is provided above the reef, and a fixed radio wave transmitter is provided from the radio wave transmitter. 2. Description of the Related Art It has been practiced to catch a radio wave transmitted every time on land via a communication satellite, for example, so that the position of a sea surface reef can be constantly monitored. This is in preparation for drifting of the sea reef due to breakage of the mooring line, and when the mooring line breaks and the sea reef drifts,
Since the position of the sea surface reef caught on land shifts, drifting can be detected by this, and the drifting position can be determined, so that the recovery can be facilitated.

[0003]

However, in the case of a sea surface reef equipped with the above-mentioned radio wave transmitter, since the radio wave transmitter has to be activated at regular intervals, the power source must be replaced at regular intervals. It is necessary to charge the battery with sunlight or the like, and there is a problem that it takes time to manage the power supply. Also,
Since the radio wave transmitter is located on the sea surface exposed to wind waves, there is also a problem that the radio wave transmitter is easily damaged.

[0004] On the other hand, an intermediate floating fish reef moored in a floating state in the middle part of the sea via a mooring line at an anchor portion submerged on the seabed also drifts when the mooring line breaks. For this reason, it is conceivable that a floating body such as a buoy connected to the middle floating reef by a connecting cable is floated on the sea surface, and a radio wave transmitter is attached to this floating body. With this configuration, when the mooring line breaks and the middle floating fish reef drifts, the floating body connected by the connecting rope also drifts and the position changes, so that the drift is detected in the same manner as the conventional sea surface floating fish reef. be able to.

[0005] However, even if the drifting of the middle reef fish reef can be detected as described above, the problem that the power supply management is troublesome and the radio wave transmitter is easily damaged remain.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and relates to a power supply management for a middle-level floating reef which is moored in a floating state in a middle level in the sea via a mooring line at an anchor section submerged in the sea floor. It is an object of the present invention to enable drift detection by a radio transmitter while solving the problem that the radio transmitter is troublesome and easily damaged.

[0007]

For this purpose, the first aspect of the present invention is described.
The present invention provides a drift-detectable middle floating fish reef which has a radio wave transmitter that does not transmit at a mooring position and that transmits when the mooring is released and rises.

A second aspect of the present invention is a radio wave transmitter attached to a middle-level floating reef, which does not transmit at the mooring position of the middle-level floating reef, but operates when the mooring is released after the mooring is released. An object of the present invention is to provide an intermediate floating fish reef capable of detecting drifting, comprising: a radio wave receiver that detects transmission of a transmitter and notifies the floating of the intermediate floating fish reef.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the present invention will be described with reference to FIGS.

[0010] In the figure, reference numeral 1 denotes a middle floating fish reef, which is moored on an anchor portion 4 which is a heavy object such as a concrete structure while floating in a middle layer area between the sea surface 2 and the sea floor 3 as shown in the figure. Moored at

The middle floating fish reef 1 has a floating body 7 attached inside a fish reef main body 6.

The reef main body 6 is provided with a plurality of framing cords 9 by connecting a plurality of supporting rings 8 located at required intervals in the central axis direction, and the supporting ring 8 and the framing cords 9 are provided.
And a tubular body to which the net 10 is attached. The support ring 8 is an annular body made of, for example, fiber-reinforced plastic or a metal subjected to anticorrosion treatment, and forms a radial skeleton of the fish reef main body 6. The skeleton cord 9 is
For example, it is a wire made of a synthetic fiber rope, a metal wire subjected to anticorrosion treatment, or the like, and forms a skeleton in the longitudinal direction of the fish reef main body 6. The net-like material 10 is like a fishing net, and gives the reef main body 6 a surface area for promoting the growth of algae and microorganisms.

The floating body 7 is a hollow airtight container made of, for example, a fiber-reinforced plastic or a textile-treated metal, and has a sufficient buoyancy to float the entire middle floating fish reef 1. .

The mooring line 5 may be a bundle of the above-mentioned framing cords 9 or another wire connected to the framing cords 9.

A radio transmitter 11 is attached to the floating body 7 located above the middle floating fish reef 1. This radio wave transmitter 11 is submerged in the middle part of the sea together with the middle floating fish reef 1 when the middle floating fish reef 1 is at the mooring position, and does not perform transmission operation and is in a rest state. Here, the mooring position refers to an underwater middle-rise area where the middle-level floating reef 1 is to be moored in a floating state.

On the other hand, when the mooring line 5 is broken, the mooring is released from the middle floating fish reef 1 and the buoyancy of the floating body 7 causes the sea surface 2 to float.
(See FIG. 2). The radio wave transmitter 11 attached to the floating body 7 is released from the mooring of the middle-level floating fish reef 1, floats, floats, and operates to transmit, and transmits a radio signal from the antenna 12. The radio wave transmitter 11 is the middle floating fish reef 1
Is mounted at a position where at least its antenna 12 is exposed on the sea surface 2 when it floats on the sea surface 2.

The transmitting operation of the radio wave transmitter 11 associated with the ascent can be performed by, for example, turning on a power switch based on a pressure change caused by the ascent.
In some cases, a power switch can be turned on to perform a transmission operation by sensing light when the user ascends from the middle layer area in the sea to the sea surface 2.

A radio wave transmitter 11 attached to the middle floating fish reef 1 detects a transmission of the radio wave transmitting device 11 and notifies a rising of the middle floating fish reef 1 (not shown).
And a drift detection device.
The radio wave receiver is usually installed on land (can also be installed on a ship), and receives the transmission of the radio wave transmitter 11 directly or via a satellite or the like, and notifies the drift of the middle floating fish reef 1. Things. In addition, if the radio wave receiver notifies not only the drift of the middle floating fish reef 1 but also the drift position, the collection becomes easy.

Next, another example of the present invention will be described with reference to FIGS. 1 and 2 denote the same members.

In the present example, the middle floating fish reef 1 is composed of
The fish reef main body 6 is composed of a fish body 10 and a large number of floating bodies 7 housed in the fish reef main body 6.

In the case of the middle floating reef 1 as in this embodiment, when the mooring line 5 is broken and the mooring is released, the mooring line 5 is deployed on the sea surface 2 as shown in FIG. Also, since the floating body 7 is relatively small, the radio wave transmitter 11 is directly attached to the floating body 7.
Is installed, it is difficult to reliably expose the antenna 12 on the sea surface 2 when the mooring of the middle-level floating reef 1 is released and the surface floats. For this reason, the radio wave transmitter 11 in this example is provided with an auxiliary floating body 14 on the connecting rope 13 connected to the middle floating fish reef 1, and the radio wave transmitter 11 is provided on the auxiliary floating body 14.
Is attached. By doing so,
When the middle floating fish reef 1 drifts, the radio transmitter 11
Can be exposed on the 12 sea surface 2.

Also in this example, the radio wave transmitter 11 transmits when the mooring of the middle floating reef 1 is released and the surface floats, and the radio wave receiver (not shown) detects this transmission and detects the transmission. Is notified in the same manner as in the above example.

[0023]

The present invention is as described above. When the radio wave transmitter 11 is at the mooring position and the transmission is not in operation when the middle floating fish reef 1 is at the mooring position, the mooring of the middle floating fish reef 1 is performed. When the midwater fish reef 1 is at the mooring position, the power is hardly consumed in normal times when the middle reef 1 is at the mooring position, and the trouble of power management is greatly reduced. Further, the radio wave transmitter 11 is usually located in the middle layer in the sea, and is less susceptible to wind waves, so that the risk of damage is small.
