Description

[Detailed Description of the Invention] [Technical Field J] The present invention generates a water flow from one end of a small pool body, and swims against this water flow, allowing swimming to be enjoyed in a space-saving and energy-saving manner. This relates to a flowing pool.

[Background technology] Swimming is a sport that many people do in order to maintain and improve their health. Therefore, in order to save space, a water current is generated from one end of a small pool, and the swimmer swims against this swimming force. A small dry running water pool is being developed.

As shown in Figure @7, such a small running water pool is an application of the circulating water MI50 for hydraulic experiments on ships. It is 2m wide and 1m deep.

A swimming part 51 with a length of about 5 m is provided in the water tank 50, and a water flow generating propeller 52 and a rectifying part 5 are provided in the water tank 50.
3 to generate a uniform water flow on the r surface. In this case, a uniform flow is preferable for swimming, but such a recirculation water tank 50
However, since the rectifying section 53 is thick, the installation area becomes large, and in addition, large power is required to generate a uniform flow over the entire cross section, and the cost is high, which is not sufficient.

Therefore, as shown in FIGS. 8 and 9, a nozzle 1 is installed at one end of the pool body 1 to discharge water into the pool body 1.
0, a circulating water outlet 3 is provided at the other end of the pool body 1, the nozzle 10 and the circulating water outlet 3 are connected by a circulating hose 4, and a pump 5 is attached to the circulating hose 4.
A running water pool has been developed in which water is continuously caused to flow into the pool body 1 from seven nozzles 10 by driving.

In this pool, the water spouted into the pool body 1 from the nozzle 10 generates a surface flow F in which only the surface layer of the pool body 1 flows, and as shown in FIG. Since there is no need to flow the fluid, the power of the pump 5 can be reduced, and the rectifier 53 is also unnecessary, which is advantageous in terms of cost and installation location. However, this flowing pool has a drawback in that the water ejected from the nozzle 10 forms a localized current, making it difficult to swim.

[Object of the Invention] The present invention has been made in view of the above points, and provides a flowing water type that not only requires less power but also allows a stream of uniform width to flow into the pool, making it easier to swim. The purpose is to provide a swimming pool.

[Disclosure 1 of the Invention That is, the flowing water pool according to the present invention includes a pool body 1
A water flow generator 2 for discharging water into the pool body 1 is installed at one end of the pool body 1, and a circulating water outlet 3 is provided at the other end of the pool body 1 to generate water flow *! 2 and the circulating water outlet 3 are connected with a circulation hose 4, and a pump 5 is attached to the circulation hose 4, and the pump 5 is driven to generate a water flow *W
This is a running water pool in which water flows continuously into the pool body 1 from a water flow generating device 2, and a horizontal discharge pipe 6 provided in the water flow generating device 2 is disposed near the water surface of the pool body 1. At the same time, the discharge nozzle 6 is opened toward the pool body 1 side to allow a flow of uniform width to flow into the pool body 1 from the discharge nozzle 6, and the flow velocity of this surface flow F is set to 0.7 to 1 from the discharge nozzle 6. .5 The speed is set to 0.5 to 1.5 m/sec at a distance from the discharge nozzle, and the width W of the surface flow F is set to about the width of a person's shoulders at a distance of 0.7 to 1.5 m from the discharge nozzle. It is characterized by the fact that it generates water flow only on the surface of the pool body 1 to form a surface flow F, which reduces power consumption, and also allows the water to flow uniformly within a certain range of speed. The above object is achieved by allowing the water to flow into the pool body 1.

The present invention will be described in detail below based on examples. As shown in Figures 1 and 3, the pool body 1 is formed of concrete or metal plates such as iron plates, aluminum plates, and stainless steel plates, or synthetic resin plates such as FRP, and the size of the pool body 1 is limited. Although it is not a thing, for example, width 2.2 theory,
Length 4.5m.

It can be formed with a water depth of 0.9 m and a capacity of about 9 aff. A water flow generator RA2 is installed at one end of the pool body 1 in the longitudinal direction, and a plurality of circulating water outlets 3 are bored at the other end of the pool body 1. The water flow generation device 2 is formed in a cylindrical shape, and as shown in FIGS. 4 to 6, an opening 11 having a width of about 5 to 101 mm and continuous in the longitudinal direction is bored in the circumferential surface of the water flow generation device 2. A guide protrusion 12 is provided protruding from the edge of the opening 11.
A slit-shaped discharge nozzle 6 is formed between the angles 12 and 12. *Also, the discharge nozzles 6 may be arranged in a plurality of vertical rows in parallel. Further, fixing pieces 13 are provided at both ends of the water flow generating device 2, and mounting holes 14 are bored in the fixing pieces 13. The water flow generator 2 is disposed in a recess 15 formed in a side wall at one end of the pool body 1, and an introduction pipe 16 fixed to the side wall of the pool body 1 is connected to a mounting hole of the water flow generator 2. 14 , and the water flow generator 2 is supported by this introduction pipe 16 . An O-ring 17 is interposed between the introduction pipe 16 and the attachment hole 14, and the water flow generator 2 is rotatably supported by the introduction pipe 16 and water-tight by the O-ring 17. In addition, a rectifying plate 19 having a water passage port is provided in front of the discharge/slip 6 in the water flow generation device 2, and a rotation adjustment ratchet that comes into contact with the side surface of the water flow generation device 2 is provided at the end of the introduction pipe 16. In the figure, 20 is a header formed in a cylindrical shape, both ends of the header 20 are closed, and the header 20 has two connection parts 22 and three connection parts 21.
is provided.

On the other hand, a circulating water outlet 3 is provided at the other end of the pool body 1.
m holes are formed, and each circulating water outlet 3 is connected to a connecting portion 21 of the header 20 with a circulating hose 4.

A bow 5 is attached to each of the circulation hoses 4, and a regulating valve 23 for adjusting the water flow is provided. Then, the connecting portion 22 of the header 20 and the introduction pipe 16
and are connected by a 7 flexible hose 24.

Next, to explain the flow of water, water in the circulation hoses 4 flows by driving the pump 5, enters the header 20 from each circulation hose 4, and then passes through the hose 24 from the connection part 22 of the gamma goo 20 to the header 20. The water flows into the water flow generator 2 from the inlet 8 of the inlet pipe 16 .

At this time, as shown in FIG. 1, this water flow generating device 2 is placed in a position near the water surface inside the pool body 1 and is long in the horizontal direction.
Since the discharge/spool 6 is open to the pool body 1 side,
The water discharged from the discharge nozzle 6 flows only on the surface layer of the water in the pool body 1. Therefore, by swimming against this surface flow F, the water in the pool body 1 flows as usual. There is no need to flow the entire amount of water, and it requires less power, allowing you to enjoy swimming economically. The depth of this surface flow F from the water surface may be such that the water flow hits the swimmer's body, for example, about 30 cm from the water surface. Here, the flow velocity of the surface flow F discharged from the discharge/spool 6 into the pool body 1 is 0.
．． 0.5-1.5m at a distance of 7-1.5m
/second. In other words, when swimming in a pool, it is best to position the swimmer's chest within 0.7 to 1.5 m from the discharge jet 6 to prevent hands from hitting the side walls of the pool body 1. In addition, the flow of the surface flow F can be effectively applied to the eyebrows and chest area where water resistance is large, and the distance L1 from the discharge 7 nozzle 6 is 0.
If it is less than 7m, your hands may touch the spout/slip 6 or the full wall of the pool body 1 when swimming.
Further, if the distance L2 from the discharge nozzle 6 exceeds 1.5 m, the flow velocity of the surface flow F becomes low, and it is necessary to increase the flow velocity of the surface flow F, which is not preferable from the viewpoint of energy saving.

Then, within the range from Ll to L2, the surface flow F
By setting the flow rate to 0.5 to 1.5 ω/sec,
This is the most preferred exercise for swimmers, calculated from the desired heart rate during exercise. Next, the relationship between swimming speed and oxygen intake in each swimming style of breaststroke, crawl, backstroke, and butterfly is shown in Figure 2, and the flow rate of surface flow F is 0.5 to 1 By setting the speed to .5 m/sec, it is possible to correspond to each swimming style.

In other words, if the speed of each direction of play and the speed of the surface flow F are made to almost match, swimmers can swim while stopping at a nearly constant position within the pool body 1, and Not only does it allow continuous swimming just like in a pool, but it also allows for the most suitable exercise depending on the swimmer's swimming style and ability. In addition, in the f52 diagram, 0 indicates the case where the swimmer used the hands and feet, K indicates the case where only the feet were used, and P indicates the case where only the hands were used.

Also, at a position similarly 0.7・-1.5 m away from the discharge/slip 6, the width W of the surface flow F is the shoulder I width of a person (30 to 8
By setting the pool to approximately 0 co+), the surface flow F can be effectively applied to the human body with less power, and there is no need to generate the surface flow F throughout the pool, resulting in energy savings.

The flow rate of this surface flow F can be adjusted by rotating the regulating valve 23 provided on the circulation hose 4 or the water flow generator 2. Since the water current generating device 2 is provided on the surface of the pool body 1, the water current generating device 2 can be easily rotated by hand, allowing swimmers to adjust the water current generating device 2 according to their swimming style. It is possible to freely change the flow velocity of the surface flow F. In addition, since the water ejected from the discharge nozzle 6 spreads in a uniform layer on the ice surface, the velocity distribution of the surface flow F in the width direction of the pool body 1 is small, making it easy to swim. .

In the figure, 25 is a heat exchanger that heats water in the pool, and 26 is a filter. The filtration pump 27 of the filter 26 and the filtrated water outlet 28 provided at the end of the pool body 1 are connected by a hose 29, and the filtration pump 27 of the filter 26, the five-way valve 30, and the sand filter 31 are connected. They are connected to each other, and the filtered water is returned and sent into the water flow generator 2. Also, return pipe 3
A heat exchanger 25 is connected to 2, and the water can be heated appropriately by operating a valve 30. In the figure, 34 is a water collection bit, 35 is an adjustment pipe for adjusting the height of the water surface provided at the rear of the pool body 1, 36 is an over 70-ro,
45 is 7 lunges.

[Effects of the Invention 1] As described above, the present invention has a water flow generating device having a horizontally long discharge nozzle installed at the end of the pool body to discharge water into the pool body. It is possible to generate a surface flow in the width direction of the pool, requiring less power for swimming, and because the discharge nozzle is long in the horizontal direction, it is possible to obtain a surface flow with an almost uniform velocity distribution in the width direction of the pool. , even beginners can easily enjoy swimming. In addition, the flow velocity of the surface flow on the ice surface discharged from the discharge nozzle into the pool body was set to 0.5 to 1.5 at a position 0.7 to 1.5 minutes away from the discharge nozzle.
m/sec, and the width of the surface flow is set to about the width of a person's shoulders, so the surface flow generated with a small amount of power can be effectively applied to the swimmer, and exercise physiology can be achieved in a small space and with less power. This is something that can achieve the effects of swimming.
