Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a high-pressure experimental aquarium used for long-term rearing, cultivation, etc. of deep-sea organisms.

[Prior Art] For example, just as squid pigments have encouraged the development of liquid crystal technology, the field of marine biology is a field that is expected to greatly contribute to industry. In particular, deep-sea organisms are not only a material contribution, but also a life form that has survived under conditions of poor nutrition and being completely cut off from light. It is also attracting attention as a valuable resource.

However, when deep-sea organisms are brought back to sea, they die in a short period of time due to drastic changes in environmental conditions, making it impossible to continue research under normal conditions.Therefore, there is a desire for technology to raise or cultivate them in an observable state. There is.

[Problems to be Solved by the Invention] The above-mentioned conventional research on deep sea organisms had the following problems to be solved.

In other words, even if deep-sea organisms were collected by a deep-sea research vessel, if the deep-sea research vessel surfaced, the environmental conditions, especially the pressure, would change and the deep-sea organisms could die. . As a means of surfacing to the surface using deep-sea organisms, a proposal has been made to collect deep-sea organisms in pressure-resistant containers.

However, the shape and weight of the pressure vessel are limited because the pressure vessel is transported to the deep sea by a deep-sea research vessel. However,
Even if deep-sea organisms are collected in small pressure-resistant containers, it is difficult to raise and cultivate them for long periods of time.

In order to solve this problem, the present invention provides a high-pressure experimental aquarium that allows living organisms collected in a pressure-resistant container in the deep sea to be transferred from the pressure-resistant container without changing the environmental conditions, and at the same time allows for long-term rearing and cultivation. With the goal.

[Means for Solving the Problems] As a means for solving the above problems, the present invention provides a disc-shaped pressure wall that is rotatably provided around the center of a circular surface and partitions the inside of a pressure container into a main chamber and a sub-chamber; The pressure-resistant wall has a main chamber opening that can be opened and closed by a main chamber opening cover outward from its rotation center and communicates between the main chamber and the sub-chamber, and a main chamber opening that can be opened and closed by a sub-chamber cover in the sub-chamber. A manipulator is provided to allow access to both the main chamber and the sub-chamber and to be remotely controlled from the outside, and a manipulator is provided to allow the interior of the main chamber and the sub-chamber to be observed from the outside. An object of the present invention is to provide a high-pressure experimental water tank characterized by being equipped with a monitoring window.

[Effect]

Since the present invention is configured as described above, it has the following effects.

That is, a pressure-resistant container containing deep-sea organisms is placed into the sub-chamber through the sub-chamber opening of a high-pressure experimental aquarium, and after the sub-chamber is sealed with a sub-chamber lid, seawater is injected to create a deep-sea environment. While looking through the observation window, the creature is removed using a manipulator.
Similarly, open the main chamber opening cover of the pressure wall that slowly closes the main chamber, which is already in a deep sea environment by injecting seawater, and rotate the pressure wall so that the opened main chamber opening is directly above the main chamber. However, by transporting deep-sea organisms into the main chamber using a manipulator, it becomes possible to transfer the living deep-sea organisms to a high-pressure experimental aquarium without changing the environment, where they can be reared or cultured for long periods of time.

[Example] High-pressure experimental water tank according to an example of the present invention Fig. 1~
This will be explained with reference to FIG.

FIG. 1 is a longitudinal sectional view of the high-pressure experimental water tank l of this embodiment, and FIGS. 2 to 4 are diagrams for explaining its function (operating procedure). First, the outline of the configuration will be explained with reference to FIG. 1, and the detailed explanation will also be given along with the explanation of the operation in FIGS. 2 to 4.

In FIG. 1, a high-pressure experimental water tank 1 consists of a main chamber 2 in which deep-sea organisms (not shown) can be kept and cultured for a long period of time, and a sub-chamber 3 in which deep-sea organisms are carried in and out of the main chamber 2. The main chamber 2 is provided with a main chamber lid 16 that can be rotated to open and close by operating the main chamber/lift handle 15 and the main chamber lid rotation mechanism 17, and the sub chamber 3 can also be opened/closed by operating the sub chamber lid lift handle 5, etc. A possible secondary chamber lid 4 is provided. Note that the main chamber lid 16 also serves as a pressure-resistant wall that partitions the main chamber 2 and the sub-chamber 3. Further, a multi-joint manipulator 9 that can reach any part of the main chamber 2 or the sub-chamber 3 is provided inside, and is used for gripping, moving, etc. the deep sea creatures to be reared.

A main room monitoring window 20 is provided on the side wall of the main room 2, and an auxiliary room monitoring window 12 is provided on the side wall of the auxiliary room 3, for operating the manipulator 9 at that time, observing the rearing status of deep sea creatures, and other internal observations. . At the bottom of the main chamber 2, a bottom mud section 19 is formed of mud from the seabed, which has been added as a culture medium for deep-sea organisms.

Next, the procedure for transporting the deep sea creatures 1 will be explained with reference to FIG. In addition, to avoid complications, please refer to Figures 2 to 4.
In the figure, the minute members shown in FIG. 1 are omitted. Rotate the sub-chamber lid lifting handle 5 to lower the sub-chamber lid 4 attached to the sub-chamber 3 into the sub-chamber 3, and use the sub-chamber lid rotation handle 6 to lower the sub-chamber lid 4.
Rotate horizontally to open the antechamber opening 7, and carry in the pressure container 8 containing deep-sea organisms collected by a deep-sea research vessel or the like through the antechamber opening 7. (by means). At this time, the manipulator 9 is rotated to a position where it does not become an obstacle by the manipulator rotation mechanism 10 so that it does not become an obstacle to carrying in the pressure-resistant container 8.

Next, as shown in FIG. 3, use the sub-chamber cover rotation handle 6 to rotate the sub-chamber cover 4 and return it to its original position, and use the sub-chamber cover lift handle 5 to raise the sub-chamber cover 4, opening the sub-chamber opening. 7 is closed, and seawater is poured into the subchamber 3 from the subchamber seawater inlet 11 to increase the pressure to the same as deep sea conditions. The manipulator 9 is rotated to the working position by the manipulator rotation mechanism 10, and the pressure vessel 8 is opened and the deep sea organisms are taken out while observing through the subchamber monitoring window 12 using the manipulator 9.

Finally, as shown in FIG. 4, seawater (not shown) is poured into the main chamber 2 from the main chamber seawater inlet 13 to maintain the same conditions as deep sea conditions. Next, move the main chamber opening lid 14 to the main chamber lid lifting handle 1.
5 to connect the main chamber 2 and auxiliary chamber 3, the main chamber 116 is rotated by the main chamber lid rotation mechanism 17, and the main chamber opening 18 is connected to the main chamber 2.
The deep-sea creature O1 is placed on the bottom mud section 19 provided at the bottom of the main chamber 2 by operating the manipulator 9 while observing it through the monitoring window 20 inside the main chamber.

Thereafter, the manipulator 9 is pulled up from inside the main chamber 2, the main chamber lid 16 is rotated and returned to its original position, the main chamber opening lid 14 is raised, and the inside of the main chamber 2 is sealed. In the main room 2, the deep sea creatures 01 are kept or cultivated for a long period of time while observing their condition through the main room monitoring window 20.

In addition, long-term rearing or cultured deep-sea organisms O1 are stored in the main room 2.
If you want to take it out from inside, take it out by reversing the loading procedure.

The manipulator 9 is a multi-joint manipulator that is driven by remote control from outside the high-pressure experimental water tank 1, but the signal cotton 21 for operating each joint and the manipulator rotation mechanism 10 is taken out from within the shaft of the main chamber lid rotation mechanism 17. It is configured as follows.

As described above, according to this embodiment, the high-pressure experimental aquarium 1 is configured to be divided into two chambers, the main chamber 2 and the sub-chamber 3, and communicated with each other, so that even when carrying in and out of deep-sea organisms, the main chamber 2 is always kept in the deep sea. It has the advantage of being able to maintain considerable pressure conditions. Furthermore, since the Mayubinilator 9, which can be remotely controlled from the outside, is provided inside, there is an advantage that deep-sea organisms can be freely handled, such as grasping and moving, while maintaining high pressure conditions.
