It is possible to enter in the middle of 16. In addition, it is possible to attach the aqualung and descend in the underwater cylinder 10 to enter the pressurizing chamber 6, and to swim in the waterway 16 with the aqualung attached, or to remove the aqualung and swim. . In this case, since the upper portion of the water channel 16 is the space 17 filled with the pressurized air, it is possible to freely breathe.

Explaining the operation of this embodiment, the compressor 30
The air pressurized to about 1.5 atm is supplied into the pressurizing chamber 6 from the supply port 40 provided at the tip of the air supply pipe 38. Pressurized air in the pressurizing chamber 6 is taken in through the suction port 44,
It is supplied from the delivery port 45 through 43 into the connection body 15 and the branch body 13, and forms the space 17 above the water channel 16 in each connection body 15 and the branch body 13. In this case, the excess air is one end of the space 17, that is, the dirty air sucked from the suction port 46 at the upper part of the discharge conduit 49 arranged on the submersible cylinder 10 side is the exhaust port 48 provided at the other end of the discharge conduit. The air is circulated because it is discharged into the submersible cylinder 10 from the inside, and the lower surface of the space is adjusted so as to maintain the substantially same surface as the exhaust port 48.

The pressure in the water channel 16 and the pressurizing chamber 6 is about 5 times the height in the water column 10.
Since the water pressure at the depth of ~ 8m is applied and the pressure is about 1.3 ~ 1.5atm, swimming in the waterway 16 can experience the same water pressure as swimming in the water at the bottom of 5 ~ 8m.

When the compressor 30 breaks down and the air supply is cut off, the water in the water channel 16 first enters the air supply pipe 38, and the pressurized air in the pressurizing chamber 6 and the air chamber 17 suddenly goes out. Prevent it from leaking into. In the unlikely event that a part of the air supply pipe 38 is destroyed and the check valve 39 does not operate, the pressure in the pressurizing chamber 6 and the space 17 is gradually decreased and the water level rises, and the air supply pipe It is safe for swimmers in the waterway 16 to prevent water from leaking until the water enters the water 38 and the water level in each submersible cylinder 10 and the connecting body 15 falls below the supply portion 40 of the air supply pipe 38. .

Space in the pressurizing chamber 6 and on the water channel 16 in the connector 15 and branch body
Since the temperature of the exhaust gas discharged from the body of the swimmer is high, it rises in the inside of the swimmer 17, sucks it through the suction port 44 arranged on the ceiling, and discharges it from the sending port 45. That is, the air sent from the air supply pipe 38 into the pressurizing chamber 6 is sent to the air chamber 17 from the suction port 44 installed on the ceiling, through the air sending pipe 43, and then the discharge conduit 49.
Since it is taken in through the suction port 46 and discharged through the exhaust port 48 into the submersible cylinder 10, convection of air in the pressurizing chamber 6 and the space 17 is promoted, and fresh air always flows in.

The height difference between the supply port 40 of the air supply pipe and the outlet port 45 of the air supply pipe 43 is set so that the position of the outlet port 45 is lower than the position of the supply port 40 by 50 to 100 mm or more and the air pressure in the pressurizing chamber 6 is slightly increased. This prevents the entry of water into the pressurizing chamber 6, and further supplies air so that the air flows into the space 17 in the connector 15.

The pressurizing chamber 6 is used not only as a resting room when swimming in the waterway 16, but because the pressurizing chamber 6 is filled with pressurized air of about 1.5 atm, various exercises, aerobics, etc. It is possible to further promote metabolism and enhance the shape-up effect by breathing pressurized air while having a drink or enjoying an underwater coffee or watching a record.

When the wall surface of the space body 2 is damaged, the pressure is released and the water level in the water channel 16 rises, which is dangerous. Therefore, the space body 2 should be located at the center of the housing 1 so that the vehicle etc. will not collide. I am doing it. Further, the waterway 16 can be reached by descending the inside of the underwater cylinder 10 using a diving equipment.

"Effect of Invention" The present invention has the following effects.

Since there is a space with pressurized air above the water channel provided in the connecting body and the branch body, and breathing is possible, it is possible to enjoy diving swimming for a long time without using diving equipment.

Since the space body with the pressure chamber inside, the submersible cylinder, the branch body, and the connection body are formed in a size that can be transported by a large truck, they can be easily transported. In addition, it has the advantages that water channels can be added or changed and that construction can be done in a short time.

To improve the shape-up effect in a short period of time by spending a lot of time in the pressurized room inside the space that is connected to the connection body, such as various exercises and listening to music in a pressurized air atmosphere. Can be done.

By confirming bubbles generated from the discharge port of the discharge conduit in the underwater cylinder, it is possible to safely maintain the air supply state.
