The underwater sightseeing and experience manned submersible 100 according to the embodiment of the present invention having such a configuration is used as follows to provide underwater sightseeing and experience to passengers.

First, as shown in FIG. 6a, the buoyancy of the buoyancy bag 41 is increased or decreased through the ascending / descending system 40 so that a person can easily board the crew room of the underwater sightseeing and experience manned submersible craft 100 of the present invention. Although the submersible is positioned on the surface of the water, a large amount of power is wasted when diving again with the submersible fully exposed to the outside, so that about 2/3 of the see-through window 10 is exposed at the top. Then, a person is guided to get on between the see-through window 10 and the main body 1.

Thereafter, as shown in FIG. 6b, when boarding is completed, the buoyancy of the buoyancy bag 41 is reduced through the ascending / descending system 40, and the underwater sightseeing and experience of the manned submersible 100 for experience naturally Guide to descend.

At this time, the illumination lamp 130 is turned on so that the surrounding environment in the water can be easily classified.

Thereafter, when the descent of the submersible is completed, as shown in FIG. 6c, the propulsion system 30 is operated to start the underwater operation, and the passenger can easily tour the submarine from the perspective window 10. Can do.

At this time, since the water is infiltrated into the space between the main body 1 and the see-through window 10, the passenger is not only in simple visual sightseeing, but substantially in contact with water and body. And enjoy a high-level leisure experience that stimulates the five senses.

Here, as shown in FIG. 6c, the buoy 121 of the job classification means 120 is transferred together on the surface of the water by the operation of the submarine, so that the current position of the submarine can be easily recognized from the outside.

In addition, as shown in FIG. 6d, in the operation process of the submersible craft, the image information captured by the imaging system 80 is not only captured and stored around the operation area of the submersible through the imaging system 80. It can be confirmed and monitored externally from the video monitor 92 of the real-time monitoring system 90.

On the other hand, when the submarine is tilted to any one side in the course of operation, as shown in FIG. 6e, the level maintaining system 60 detects this and the control box 50 that receives the sensing information is positioned on the tilted side. Oxygen is supplied to the buoyancy bag 41 to increase the buoyancy, compensate the tilt of the submersible craft appropriately, and maintain the level stably.

On the other hand, as shown in FIG. 6f, when the submersible is operated for a long time, the oxygen concentration in the interior space of the see-through window 10 decreases. At this time, the interior space of the see-through window 10 through the oxygen supply system 70 is reduced. In order to maintain the oxygen concentration directly, oxygen is continuously supplied to the inside of the viewing window 10 so that the breathing of the passenger is stably maintained.

On the other hand, when a scuba diving experience is required by a passenger during the sightseeing tour of underwater, as shown in Fig. 6g, stop the operation of the submersible craft, wear scuba equipment, and easily enjoy the scuba diving experience. Can do.

As described above, when the experience such as underwater sightseeing and scuba diving is completed, as shown in FIG. 6h, after increasing and decreasing the buoyancy of the buoyancy bag 41 through the ascending / descending system 40 and positioning the submersible on the water surface, Get the passengers off and complete the underwater sightseeing experience.
