Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a high-pressure experimental tank applied to long-term breeding, culturing, and the like of deep-sea organisms.

[Conventional technology]

For example, the marine life field is a field that is expected to greatly contribute to industry, as the dyes have promoted the development of liquid crystal technology. Above all, deep-sea creatures are not just contributors to life, but as a living entity that has been completely shielded from light and has survived under poor conditions, from the perspective of exploring the mechanisms of the birth and evolution of life. It is gaining attention as a valuable resource. However, when deep-sea organisms are brought back to the sea, environmental conditions change drastically, causing them to die in a short period of time, making it impossible to continue research under normal conditions. I have.

[Problems to be solved by the invention]

The above-mentioned conventional research on deep-sea organisms has the following problems to be solved.

That is, even if a deep-sea research vessel or the like collects deep-sea creatures, if the deep-sea research vessel floats on the sea, the environmental conditions, especially the pressure, may change, and the deep-sea creatures may die. . As a means for utilizing the deep-sea creatures to float on the sea, proposals have been made to collect deep-sea creatures in pressure-resistant vessels.

However, the shape and weight of the pressure vessel are limited due to the fact that the pressure vessel is transported to the deep sea by a deep sea research vessel. However, even if deep-sea organisms are collected in a small pressure vessel, it is difficult to breed and culture them for a long time.

In order to solve this problem, the present invention provides a high-pressure experimental water tank that allows organisms collected in a pressure-resistant container in the deep sea to be transferred from the pressure-resistant container without changing environmental conditions, and that allows long-term breeding and cultivation as it is. With the goal.

[Means for solving the problem]

The present invention provides a disk-shaped pressure-resistant wall rotatably provided around the center of a circular surface and partitioning the inside of a pressure-resistant container into a main chamber and a sub-chamber, and the pressure-resistant wall is provided outside the rotation center as a means for solving the above problem. A main chamber opening provided to be openable and closable by the main chamber opening lid and communicating between the main chamber and the sub-chamber; and a sub-chamber opening provided to the above-mentioned sub-chamber to be openable and closable by the sub-chamber lid and communicating with the outside. And a manipulator provided to be able to reach both the main room and the sub-room and to be remotely controllable from the outside, and a monitoring window provided to be able to observe inside the main room and the sub-room from the outside. It is intended to provide a high-pressure experimental water tank characterized by the following.

[Action]

The present invention has the following effects because it is configured as described above.

That is, a pressure-resistant container containing deep-sea organisms is put into the sub-chamber through the sub-chamber opening of the high-pressure experimental tank, and the sub-chamber is sealed with the sub-chamber lid,
Seawater is injected to create a deep-sea environment, and the deepwater organisms are carried out from the inside of the pressure-resistant container through a monitoring window using a manipulator. The main chamber opening lid is opened, the pressure-resistant wall is rotated so that the opened main chamber opening comes directly above the main chamber, and the deep-sea organisms are carried into the main chamber by the manipulator, so that there is no change in the environment. The organism can be transferred to a high-pressure experimental water tank with the organism alive, and can be bred or cultured for a long period as it is.

A multi-joint manipulator 9 that can reach any part of the sub-chamber 3 is provided inside, and is used for gripping, moving, and the like of deep-sea creatures to be bred. At this time, a main room monitoring window 20 for operating the manipulator 9 and breeding conditions of the deep-sea organisms and other internal observations is provided on a side wall of the main room 2 and a sub-room monitoring window 12.
Are provided on the side walls of the sub chamber 3 respectively. At the bottom of the main chamber 2, bottom mud 19 is formed by mud on the seabed that has been introduced as a medium for deep-sea organisms.

Next, a procedure for carrying the deep-sea creature 1 will be described with reference to FIG. 2 to 4, the fine members shown in FIG. 1 are omitted for the sake of simplicity. Sub-room 3
The sub-chamber lid 4 attached to the sub-chamber lid is lowered into the sub-chamber 3 by rotating the sub-chamber lid raising / lowering handle 5, and the sub-chamber lid 4 is horizontally rotated by the sub-chamber lid rotation handle 6 to open the sub-chamber. The part 7 is opened, and a pressure-resistant container 8 containing deep-sea creatures collected by a deep-sea research vessel or the like is carried in from the sub-chamber opening 7 (the carrying-in is performed manually or any other means). At this time, the manipulator 9 is rotated by a manipulator rotating mechanism so as not to hinder the loading of the pressure-resistant container 8.
Rotate and move to a position that does not interfere with 10.

Next, as shown in FIG. 3, the sub-chamber cover 4 is rotated and moved back to the original position by the sub-chamber cover rotation handle 6, and the sub-chamber cover 4 is raised by the sub-chamber cover raising / lowering handle 5, and the sub-chamber opening is opened. Close 7 and sub room 3
The inside is filled with seawater from the sub-room seawater inlet 11 and pressurized to make it the same as the deep sea condition. The manipulator 9 is rotated to the working position by the manipulator rotation mechanism 10 and the manipulator 9 is moved.
While observing from the sub-room monitoring window 12, the pressure vessel 8 is opened to take out deep-sea creatures.

Finally, as shown in FIG. 4, seawater (not shown) is introduced into the main chamber 2 from the main chamber seawater inlet 13 so as to be the same as the deep sea condition.

Arrives on the main room 2, and the manipulator 9 is operated to place the deep-sea creature 01 on the bottom mud portion 19 provided at the bottom of the main room 2 while observing from the main room monitoring window 20.

After that, the manipulator 9 is pulled up from the main chamber 2,
The main chamber lid 16 is rotated back to the original position, the main chamber opening lid 14 is raised, and the interior of the main chamber 2 is sealed. In main room 2, deep-sea creatures
While observing the situation of 01 from the main room monitoring window 20, long-term breeding or culturing is performed.

In addition, long-term reared or cultured deep-sea creatures 01
When taking it out from inside, take it out by the reverse procedure of loading.

The manipulator 9 is a multi-joint manipulator that is driven by remote control from outside the high-pressure experimental water tank 1. Signal lines for operating each joint and the manipulator rotation mechanism 10 are provided.
Reference numeral 21 is configured to be taken out from the axis of the main chamber cover rotating mechanism 17.
