Since the diving training water tank having the above-described structure is equipped with three systems, that is, a circulation filtration system, a movable floor system, and a monitoring system, it is very convenient for a diver who conducts training. That is, because of the circulation filtration system, the diver can always comfortably train in clean water. Also, since there is a movable floor system, the depth of training can be set arbitrarily, that is, for example, it can be set shallow for beginners and deep for skilled workers, and the diver can train at the optimum depth for himself. In addition, since there is a monitoring system, divers can train with the peace of mind that they will be able to cope immediately in the event of an accident, etc. Moreover, since they can talk with the instructor at all times, they can receive detailed instruction. .

In cleaning the water in the water tank body 10,
Chlorine concentration is of particular importance. In the circulation filtration system having the above configuration, the water returned into the water tank body 10 is
The air is blown out not only from the air outlet 93a provided at the upper end but also from the air outlet 93b provided at the middle in the depth direction. For this reason, the chlorine added to the filtered water diffuses not only from the upper end but also from the middle in the water tank body 10. Therefore, the diffusion rate becomes faster, and the uniformization of the chlorine concentration is quickly achieved and sufficiently maintained.

The movable floor system configured as described above operates as follows. When the control unit 70 sends a current for normal rotation to the motor 68 of each drive unit 60, the motor 68 will move to the arrow A
Rotating in the direction, the short link chain 51 is pulled up, and thus the movable floor 30 rises. When the movable floor 30 reaches a desired depth position, the control unit 70 cuts off the current sent to the motor 68. As a result, the brake of the motor 68 is actuated, the rotation of the motor 68 is reliably stopped, and the movable floor 30 is stopped and maintained at the desired depth position. When lowering the movable floor 30, the control unit 70 may send a current for reverse rotation to the motor 68 of each drive unit 60. If the frequency of the current supplied to the motor 68 is changed, the rotation speed of the motor 68 changes and the up-and-down speed of the movable floor 30 changes.

In the above operation, the control unit 70 detects that the movable floor 30 has reached the desired depth position based on a signal from an encoder that detects the rotation speed of the motor 68. That is, the control unit 70 can calculate the depth position of the movable floor 30 from the rotation speed of the motor 68.

The movable floor 30 moves in the vertical direction while rotating the roller 32a which is in contact with the inner wall of the water tank body 10 and the roller 32b which is in contact with the vertical pipe 12a of the handrail 12. At this time, the handrail 12 functions to guide the movable floor 30. Moreover, the devices provided in the water tank body 10, that is, the camera 121, the underwater microphone 142, the terminal 14
Since 3 is provided on the inner wall of the water tank body 10 inside the handrail 12, it does not interfere with the movement of the movable floor 30. Therefore, the movable floor 30 moves smoothly in a stable state.

The short link chain 51 is more resistant to twisting than a roller chain, for example, and is therefore difficult to break.
Therefore, the movement of the movable floor 30 in the vertical direction is performed with high safety. Further, since the movable floor 30 is suspended by the four short link chains 51, it is stable in a horizontal state. Further, since the short link chain 51 is difficult to cut, there is no possibility that a plurality of short link chains will be cut at once, and even if one is cut, the remaining 3
The book keeps the movable floor 30 sufficiently stable.

When the short link chain 51 is broken during the above operation or stop, the lower sprocket 62 is
Becomes lower, and the load applied to the load cell 71 becomes extremely small. This change is transmitted to the control unit 70,
The current sent to the motor 68 is shut off by the control unit 70. Therefore, the operation is stopped and the accident is prevented from spreading.

In the monitoring system having the above structure, the entire monitoring system is controlled by the monitoring monitor section 100.
For example, when the movable floor 30 is at a depth of 10 m, the monitoring monitor unit 100 operates the camera 122 at a depth of 10 m while zooming and the like.
The camera 121 at a depth of 8 m is operated. Then, the shadow image is displayed on the monitor of the monitor monitor unit 100 and, if necessary, also displayed on the enlargement monitor for monitoring.
Further, the diver can use the underwater microphone 142 and the terminal 143 at a depth of 10 m as the conversation device. Even if the underwater speaker 141 is located at a depth of 5 m, the depth of 1
The diver at the 0 m position can fully hear the sound from the underwater speaker 141. Furthermore, a person outside the aquarium body 10 can observe the training of the diver using the second viewing window 130 from the top. As a matter of course, the illuminating device is provided with a ceiling light 111 and a lateral illuminating lamp 11 at a predetermined position so as to obtain the brightness required for diver training, photographing and observing the diver.
2 works.

Further, in the water tank for diving training having the above construction, since the water tank body 10 is provided in a non-contact manner with the building, even if an earthquake occurs, it will not be shaken from the building, and the damage due to the earthquake will be almost eliminated. It never happens.

Further, for example, urethane is sprayed on the outer surface of the water tank body 10, so that heat retention and dew condensation prevention can be achieved.

[0028]

[Other Embodiments] On the back surface of the movable floor 30, a bucket containing a chlorine agent in a water-permeable state may be provided so that the chlorine agent is directly eluted into the water tank body 10. Combined with the configuration of the outlets 93a and 93b in the above-described embodiment, the chlorine concentration can be made uniform more quickly.

Further, the depth position for setting the photographing device, the lighting device, the conversation device, etc. is not limited to the position in the above-mentioned embodiment, but may be arbitrarily set at a position which is frequently used in training.

The position of the outlet 93b is not limited to the middle as long as it is below the outlet 93a.
