Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an underwater living facility that allows a person to experience normal life underwater.

``Conventional technology'' Recently, it has been proposed to establish underwater living facilities for the purpose of underwater observation and leisure sports in the sea, lakes, rivers, etc., and some have been experimentally created in Japan. There is. This underwater living facility is designed to allow people to experience the same life underwater as they do on land for a certain amount of time, and it allows them to experience a change in their way of thinking due to a marked change in their living environment. It is intended to enable

This underwater habitat is constructed by injecting high-pressure air into an airtight space made up of walls and maintaining the interior at a pressure higher than the water pressure, allowing the entrance and exit in the bottom wall to remain open. The system is designed to prevent water from entering even when the air is injected, and excess air generated as a result of the air injection is discharged into the water from the above-mentioned inlet/outlet.

``Problem that the invention aims to solve'' However, the exhaust noise of excess air is relatively loud, and since the entrance is located in a part of the room, this exhaust noise becomes noise inside the room. Ta. In particular, if the person inside the room suddenly stands up or falls down, the internal pressure increases and more air than usual is exhausted, making the exhaust noise louder and disturbing daily life, as well as interfering with conversation and sleep. It was hot.

Also, one of the major meanings of this underwater living facility is that it allows you to observe the ecology of underwater organisms such as fish and shellfish, plankton, etc. while you are living your normal life. , the fish and shellfish may become wary and run away, resulting in the dissatisfaction of not being able to observe them sufficiently.

This invention was devised to solve the above-mentioned problems, and aims to minimize the noise of excess air being discharged inside an underwater residential facility, making it possible to live comfortably inside the facility. The purpose is to

``Means for Solving the Problems'' This invention consists of a top wall, side walls, and a bottom wall.The bottom wall has an entrance and exit, is installed underwater, and pressurized with high-pressure air to keep the interior airtight. An exhaust pipe communicating with the air chamber space is protruded outward from the lower part of the side wall of the house body formed in the room space, the tip of the exhaust pipe is closed, and an exhaust hole is formed in the lower wall portion. It is established and configured.

"Function" With the above-mentioned configuration, the house body installed underwater is composed of a top wall, side walls, and bottom wall, and the interior is formed into an airtight air chamber space by pressurizing high-pressure air. Therefore, you can have the same experience of living inside as you would on the ground. In this case, entry and exit from the interior will be done through the entrance/exit provided in the bottom wall, but as mentioned above, high-pressure air is constantly injected into the interior, so even if it is left open,
Water will not enter through this doorway.

In addition, the excess dirty air in the room is pushed out into the water through the exhaust pipe by the pressurized fresh air. Since the tip of this exhaust pipe is closed and the exhaust hole is opened in the lower wall, excess air is exhausted from the exhaust hole, and water does not enter the room. Therefore, the exhaust sound from the exhaust hole is emitted from the part that protrudes into the water and is away from the living area, so the noise does not bother you.

Furthermore, since the excess air is discharged through the exhaust hole, it becomes small bubbles, and does not create a large air pocket when discharged from a large opening such as a doorway, so the exhaust noise itself is small. Therefore, it will not affect surrounding seafood.

"Embodiment" The drawing shows an embodiment of the underwater living facility of the present invention, in which a house body 1 installed underwater has a top wall 2,
It is composed of a side wall 3 and a bottom wall 4, and an entrance 5 is opened in the bottom wall 4.The internal size is selected depending on the purpose of use, etc., and it can be either cylindrical or rectangular. The above hierarchical structure may also be used.

As an air supply means for this house body 1 whose interior is formed into an airtight air chamber space, for example, high-pressure air may be injected from an external compressor (not shown) on water or on the ground, or a predetermined amount of air may be injected into the interior. A high pressure cylinder (not shown) may be provided.

Further, although the entrance/exit 5 is always open, if the internal air pressure is kept higher than the water pressure, there is no risk of water entering from here.

Next, an exhaust pipe 6 communicating with the air chamber space is provided at the lower part of the side wall 3 of the house body 1 so as to project outward. The number of exhaust pipes 6 is determined by the capacity of the entire house body 1, the amount of pressurized air, and the like.

The tip of the exhaust pipe 6 is closed to prevent water from entering, and for the same reason, the exhaust hole 7 is opened in the lower wall portion thereof.

The number of exhaust holes 7, their diameter, etc. are also determined by the overall capacity of the house body 1, the amount of pressurized air, etc., but from the viewpoint of suppressing exhaust noise, it is better to open a large number of small diameter ones. would be good.

Note that the house body 1 is anchored to an anchor material 9 on the bottom of the water via a chain 8 or the like.

"Effects of the invention" Since the present invention has the configuration described above, it is possible to minimize the exhaust noise of surplus air discharged by pressurizing air into underwater accommodation facilities, and therefore, There are many excellent benefits such as the fact that the living inside the facility is not bothered by the noise of the exhaust, and the fish and shellfish are not alarmed by the noise of the exhaust, so it is possible to observe the natural ecology near the underwater facility. It exerts its action and effect.
