〔Example〕

An embodiment of the deep-sea organism collecting device according to the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of the deep-sea organism collecting apparatus 1, and FIG. 2 is a side sectional view of a collecting container.

The deep-sea organism collecting apparatus 1 includes a base 2, a collecting container 3 fixed on the base 2, a trap 4 arranged in front of the collecting container 3, and a holding container for holding the pressure in the collecting container 3. And a pressure device 5.

More specifically, the base 2 is for landing on the seabed, and is equipped with a battery inside. A sampling container 3 and a support frame 6 formed as a cylindrical pressure-resistant shell are mounted on the base 2.
The buoyancy member 7 is attached via. A lid 8 that can be opened to the outside is arranged at the opening 3a at one end of the collection container 3, and a sealing lid 9 that is normally closed and can be opened as necessary is arranged at the other end.

The lid 8 is rotatably supported by a disk 11 attached to the tip of an L-shaped arm 10, and the L-shaped arm 10 is pivoted upward by a pin 12 about the pin 12. It is attached to the support base 13. A motor 14 is attached to the support 13 and is supported by a guide 15 so as to be slidable in the left and right directions.

The arm 10 is provided with a motor 16 (driving means) for rotating the lid 8. A sliding member 17 is arranged in the rear of the inside of the collection container 3, and inside the sliding member 17 and the sealing lid 9, a lid 18 into which pressure holding water is made to flow by the pressure holding device 5 is arranged.

The pressure holding device 5 is a high pressure cylinder 19, a control device 20 and a regulator.
When the sampling container 3 is pulled up from the deep sea area, the sampling container 3 is inflated by the pressure difference and the pressure increasing mechanism 22 expands the internal pressure to decrease the internal pressure. It is supplied to correct the pressure drop.

A trap 4 is arranged at the tip of the collection container 3. Specifically, the trap 4 is formed of a mesh having an inlet 24 and is supported by a holding frame 25. Then, the wire 27 wound around the roller 26 is wound around the roller 26 by operating a driving device (not shown) to pull the trap 4 toward the collection container 3 side. That is, the trap 4 is extensible and supported in front of the opening 3a of the collection container 3. A biological outlet 28 is provided in the lower middle part of the collection container 3, and a service lock 29 is provided above it.

A seawater circulation device 30 (which also serves as a purification device) is provided to prevent the seawater in the collection container 3 from deteriorating or accumulating and killing the captured organisms. Further, a hanging wire 31 is connected to suspend the deep-sea organism collecting apparatus 1 from a research ship or the like.

In such a configuration, the deep-sea organism sampling apparatus 1 opens the lid 8 outwardly, makes the trap 23 project to the front of the opening of the sampling container 3, and suspends it by the suspending wire 31 fed from the observation ship. Place on the bottom of the sea. At this time, food is appropriately placed in the trap 4. Aquatic organisms are guided by this bait and enter the trap 4 through the inlet 24. When aquatic organisms enter the trap 4, the wire 27 is wound around the roller 26 to shrink the trap 4 and move the aquatic organisms into the collection container 3.

After that, the L-shaped arm 10 is rotated to lower the lid 8 to fit it into the fitting portion provided in the opening of the sampling container 3, and drive the motor 14 to move the support base 13 to the right. The collection container 3 is closed by closing the opening of the collection container 3, and the motor 16 is operated to rotate the lid 8 to tighten it for sealing.

After capturing the aquatic organisms in the collection container 3 in this way,
The deep-sea organism collecting apparatus 1 is pulled up to the sea or land by the hanging wire 31. At this time, the collection container 3 expands due to the pressure difference between the inside and outside of the collection container 3 and the internal pressure tends to decrease. At this time, the pressure holding device 5 automatically operates to prevent the decrease in the internal pressure.

Then, after the deep-sea organism collecting device 1 is pulled up to the sea or land, the seawater circulation device 30 collects the collecting container 3 if necessary.
The seawater inside can be purified and circulated to prevent the death of aquatic life. Further, the organism outlet 28 is connected to a separately prepared high-pressure water tank, and aquatic organisms can be moved into this high-pressure water tank for breeding and observation.
