用的でない。2. Description of the Related Art In order to investigate and research microorganisms on the seabed, it is planned to collect and culture mud samples on the seabed using a submersible. In this case, the mud sample collected in the mud sampler must be kept at the pressure and temperature of the sampling sea area until it is carried into the culture device on the ground. Of these, the pressure is structured so that the pressure in the sampling area is maintained by keeping the inside of the mud collector at a high pressure. For temperature, the mud collector is generally kept in a cool box. As a heat insulating material forming a cool box, for example, syntactic foam (a product name is a micro hollow glass ball cemented with a synthetic resin) has been developed as a material with a cool effect that can withstand high pressure in the deep sea. However, since the pressure-resistant cold insulating material has a large specific gravity, the weight exceeds the loading capacity of the submarine to obtain the required cold insulating capacity, and it is difficult to design a practical cold insulating box. In addition, ice, an endothermic material utilizing a chemical reaction, and the like are conceivable, but in any case, the total weight is large due to the lack of the endothermic capacity per unit weight, which is not practical.

が要求されていた。At present, the loading capacity of a submersible is 50 kg in air weight, and the total design weight of the mud collector is limited to about 30 kg. Therefore, the design weight of the cold insulation box must be kept within 20 kg, but the design weight of the above-mentioned syntactic foam is about 50 kg, which cannot satisfy the requirement. Therefore, it has been required to develop a cooler device having a lighter structure.

なものになる。The cold storage device of the present invention is mounted on the outer wall of a submersible, and when the submersible reaches a predetermined seabed, the check valve opens due to the seawater pressure, and seawater on the seabed flows into the air source tank. To do. When the submarine rises to a certain extent after sampling, the pressure of the surrounding seawater is reduced, which closes the check valve and traps the high-seawater pressure of the seabed in the air source tank. It becomes compressed air. This compressed air is made to flow into a cold air bladder via a pressure control valve, and a mud collector is wrapped in a multi-layered air layer to keep cold. At this time, the set pressure of the pressure control valve is set so that the air layer expands in order from the inside, and by setting it so as to correspond to the decompression due to the rising of the submarine, each air layer is set to the seawater depth. Corresponding substantially uniform thickness. For this reason, unlike the single-layer air bag, the unevenness of the air pool does not occur, so that the cold insulation effect is improved.
In addition, the natural circulation in the air bag can be made independent for each layer, which improves the cold insulation effect. Since the air source tank, the cooling air bag, and the like described above can be made of plastic, the cooling device is lightweight.

Is provided with a check valve 3, a vent valve 4 and a drain valve 5 on the outer surface. The air bag 2 is connected by a pipe 6, and the other end thereof is connected to a pair of cold air bags 9 via a stop valve 7 and pressure control valves 8 1 , 8 2 , ... 8 n . The cooling air bag 9 is folded so as to face both sides of the support frame 11, and expands into a cylindrical shape during cooling to support the support frame 1.
It is designed to surround the mud collector 10 mounted on the top 1. Each cold air bladder 9 is composed of a cylindrical portion 91 and a disc portion 92, and each portion 91, 92 is divided into thin films so as to form a multi-layered air layer. Further, pressure adjusting valves 8 1 , 8 2 , ... 8 n are attached so as to sequentially send air to the respective air layers (this will be described later).

[Fig. 3] is a side view showing a state of the cold insulating device before diving. That is, the air source tank 1 is filled with the air in the air bag 2, and the cooling air bag 9 is opened on both sides. FIG. 3 is a state diagram when reaching a predetermined deep sea. At this time, the check valve 3 is opened by the pressure of the seawater, the seawater flows into the air source tank 1, and the air bag 2 is compressed by the pressure. The air bag 2 has a volume inversely proportional to the diving depth, and high-pressure compressed air can be obtained. In addition, a mud sample on the seabed is collected in the mud collector 10 by using a manipulator equipped on the submersible vessel, and is maintained at a high pressure.

包み込む。FIG. 4 shows a state in which the submersible has started to ascend after the sampling and reaches a certain depth on the way. At this time, the pressure of the surrounding seawater decreases, but since the check valve 3 closes, the inflowing seawater cannot flow out and the pressure is confined in the air source tank 1. As a result, the air in the air bag 2 cannot be expanded, and the air pressure due to the enclosed seawater pressure is accumulated in the air source tank 1. This air pressure is applied to the stop valve 7 of the pipe 6.
When opened, first, a pressure difference is generated between the pressure regulating valve 8 1 of the first air layer 9 1 of the cold air bladder 9 and the ambient seawater pressure. Then, when a predetermined differential pressure is reached, the valve membrane is broken and the pressure adjusting valve 8 1 is opened, and the compressed air in the air bag 2 flows into the first air layer 9 1 of the cold air bag 9 to cause the pressure of the surrounding seawater. Inflate this until it is balanced. As a result, the folded cylindrical portions 91 of the cooling air bag 9 extend in the directions opposite to each other, the open ends abut, and the mud collector 10 is wrapped therein.

包み込まれ保冷される。At a shallower depth, as shown in FIG. 5, the first air layer 9 1 of the cooling bladder 9 reaches the expansion limit, and when the air pressure at that time exceeds a certain set pressure, the same as above. The valve membrane of the pressure regulating valve 8 2 of the second air layer 9 2 ruptures,
The pressure regulating valve 8 2 opens and air flows into the second air layer 9 2 to inflate it until it balances the pressure of the surrounding seawater. After that, similarly, as the submersible ascends, the pressure regulating valves 8 3 , 8 4 , ... Open one after another, and the air flows in the order of the third air layer 9 3 , the fourth air layer 9 4 ,. Inflate. The last air layer 9 n is inflated as shown in FIG. 6 until the submarine floats above the sea surface.
The mud collector 10 is completely wrapped in a plurality of air layers 9 1 , 9 2 , ... 9 n and kept cool.
【００１３】このように空気層を多層にする理由は次の
とおりである。 （１）各層ごとに深度に対応した略均等な厚さの空気層
を形成させるためである。単一層の空気袋では空気量が
袋の容量近くに達するまでの間に空気溜りの偏りが生じ
保冷効果が落ちるからである。 （２）空気袋内の自然循環が各層ごとに独立に行われる
ので保冷効果が上がる。The reason why the air layer is multi-layered in this way is as follows. (1) This is to form an air layer having a substantially uniform thickness corresponding to the depth for each layer. This is because in a single-layer air bag, the air pool is biased until the amount of air reaches near the capacity of the bag, and the cold insulation effect drops. (2) Since the natural circulation in the air bag is performed independently for each layer, the cooling effect is improved.

In addition, the measured value of seawater temperature is also entered. The inner diameter of the air layer was 1 m, and the amount of enclosed air was 1 Nm 3 .
The seawater temperature θ is approximately 1 to 2 ° C. up to about 1000 m, but the temperature rises as it becomes shallower and shows a tendency similar to the change in the thickness T (mm) of the air layer. Therefore, also in this embodiment, the pressure regulating valves 8 1 , 8 2 , ... 8 n change the thickness of the air layer in accordance with the depth of seawater as shown in FIG.

In this embodiment, since the cold air bag 9 can be folded while lying down, the workability at the time of sampling is improved. In this case, an air layer 9 first root pass, as shown in FIG. 11 is formed on the guide ring so as not from hooking on bottom sampler 10, to cover the bottom sampler 10 in the next layer after (see FIG. 12 ).
