Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a circulating water tank type experimental pool in which the air pressure of the Δ-bun waterway section for practice can be freely adjusted.

<Prior Art> Conventionally, a commonly used swimming pool is a static running water pool in which a vertically long aquarium is filled with water and divided into courses. For this reason, when it is desired to give corrective guidance to the swimmer's frame during swimming practice, or to photograph and scientifically analyze the swimmer's swimming style, the instructor or cameraman has to move along with the swimmer, which is troublesome. In recent years, in order to improve the above-mentioned drawbacks, aquariums have been made into circulation aquariums (so-called running water pools), which allows swimmers to swim while remaining essentially in one spot. For example, as described in Japanese Patent Publication No. 52-13331, a circulating water tank is used and the swimmer swims in this open waterway. However, in the case of swimmers, the method of powering up is very complicated because they use all the functions of their bodies.
It can be divided into external power-up, which comes from a body shape with little resistance and a streamlined swimming style, and internal power-up, which repeatedly stimulates the lungs and muscles. At present, the high altitude 1~training method is known as a training method for internal strengthening, but it is not possible to go on an expedition to the desired high altitude one by one to practice, and it is usually limited to simply swimming in a waterway, which is a training method for external strengthening. , the effect of comprehensive power-up could not be expected.

<Problems to be Solved by the Invention> In view of the above-mentioned circumstances, the present invention provides a recirculation water tank type experimental pool in which the open waterway part of the recirculation water tank can have a B-9 oxygen concentration condition equivalent to that at high altitudes. The purpose is to provide the following.

Means for Solving the Problems> The present invention provides an open waterway for practice in which a part of a circulating water tank equipped with a sending propeller for creating running water is used as a running water pool, and an oven waterway section including this pool night. The entire area is covered with a capsule-shaped airtight chamber, and a separately provided pressure/reduction generator is connected to one end of the airtight chamber, and this airtight chamber is used as a pressure/reduction adjustment chamber.

<Function> In the case of the above (M-sized experimental pool), the water supply valve placed in a part of this recirculation aquarium is driven, and the flow water flows through the entire recirculation aquarium, and swimmers are directed to this open waterway position. As the swimmers enter and swim, the airtight chamber covering the A-Pun waterway is driven by a pressurization and depressurization generator to create a pressure condition suitable for high altitudes, adapting the swimmer's lung and metabolic functions and strengthening them internally. be.

<Example> The present invention will be described below based on the drawings of the example.

Reference numeral 1 denotes a recirculation water tank with vertical circulation, and a flow propeller 2 is provided at one end of the lower part 1a of the recirculation water tank 1 and rotated by a drive motor 21 disposed outside, and the central position of the upper part 11 of the recirculation water tank 1 is In addition to providing an open waterway 3 for practice, the entire upper part of the open waterway 3 including the pool side 4 is covered with a capsule-shaped airtight chamber 5, and one end of the airtight chamber 5 is equipped with a pressure generator connected to a pressure reduction generator 6. The pipe 8 of the receiver tank 7 faces the airtight chamber 5, and the entire inside of the airtight chamber 5 becomes a training chamber 9 for adjusting the pressure and depressurization. Also, inside this airtight room 5 there is a safety monitoring television camera 10. Lighting equipment 11, contact telephone 12. It is equipped with a measuring trolley 13 and the like, and an operation panel 15 is installed outside a viewing window 14 provided on one end wall, and a sub-chamber 1 for pressure regulation is installed outside the other end wall.
6, and the auxiliary chamber 1G and the airtight chamber 5 are configured to communicate with each other by opening and closing an airtight door 17 arranged on the #i wall.

Now, when training to strengthen the internal and external aspects of swimmers using this open waterway 3, first, inside this airtight room 5,
The pressurization/depressurization generator 6 is driven as appropriate to create atmospheric pressure and oxygen concentration equivalent to those at high altitudes (for example, high altitudes of 2000 m or higher). For example, a reduced pressure state with low oxygen concentration (q).

In this case, when swimmer A enters the airtight chamber 5, which is the adjustment chamber 1 to 1 and the noning chamber 9, he does not directly enter the airtight chamber 51, but first stays in the auxiliary chamber 16, which is the adjacent room, for a predetermined period of time. When the pressure is gradually reduced from the human pressure state and the state is such that decompression sickness does not occur, the door 17 serving as an entrance is opened to enter the airtight room 5 in the reduced pressure state. Of course, the auxiliary chamber 16 also faces the piping 8 of the pressure reduction generator 6, and the air pressure can be adjusted freely by opening and closing an appropriate valve (not shown).

In this state, if the swimmer enters the open channel 3 and swims against the flowing water B, he or she can swim while remaining in a fixed position. By doing swimming training in this way, swimmer Δ's lung and metabolic functions will be able to adapt to high-altitude conditions, leading to improved abilities. Furthermore,
These conditions are gradually increased until the atmospheric pressure and oxygen concentration are at an altitude of about 5,000 meters, giving the maximum stimulation.

In addition, external strengthening will be done by correcting swimming form in the open waterway 3 as before. At this time, the instructor (not shown) may be in the same room as swimmer A in the airtight room 5, or may be outside the airtight room 5 and look directly through the viewing window 14 or watch the monitor 18 from the television camera 10. The instructor gives indirect instruction through a microphone (not shown) while watching the video. Of course, this data of swimmer A is recorded in a measuring device 19 installed outside the airtight chamber 5. still,
In the figure, 20 is a control device for the drive motor 21, 22 is a lattice rectifier section, 23 is a contraction nostle section, 24 is a filter, and 25 is a dryer. The pressure receiver unit 7 is composed of a pressure reducing tank and a pressurizing tank, and the pressure reduction generating device O is composed of a predetermined compressor and a vacuum pump.

<Effects of the Invention> As described above, the circulating water tank type experimental pool of the present invention uses the entire open channel of the circulating water tank as a pressure adjustment training room, thereby changing the air pressure to the swimmers and exerting effects on the lungs and muscles. anaerobic and aerobic stimulation (continuously or in between)
Repeat this like 3t+ to gain internal power-up. In this case, swimmers can receive maximum internal stimulation by practicing culm twice in the morning and evening. Furthermore, as for external power-up, we can use direct corrective instruction on swimming form or scientifically analyze it while watching a video monitor to improve the technique, and in conjunction with the above-mentioned internal power-up, we can provide maximum strengthening training. It is possible to bind. Moreover, this device is designed to record various data! It is also useful for pure exercise physiology research.
