Description

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

L Background Technology J 41! Swimming is a sport that many people do in order to maintain and improve their health, but in addition to the large area required for a normal large pool, it also requires a huge amount of energy to heat the pool in the winter. There is a problem with this.

Therefore, in order to save energy and space, a small running water pool has been developed in which a water current is generated from one end of the small pool and the swimming pool is configured so that the swimmer swims against the water flow.

As shown in FIG. 7, an example of such a small running water pool is one that is an application of circulating water [50] for hydraulic experiments on ships. A swimming part 51 with a width of 2 m, a water depth ILI, and a length of about 5 mm is provided in the water WJ 50, and a water flow with a uniform cross section is generated by a water flow generating propeller 52 and a rectifying part 53 arranged in the water tank 50. It was designed to let you do so. In this case, a uniform flow is preferable for swimming, but in such a recirculation water tank 50, the rectifying part 53 is thick, so the installation area becomes large, and it is difficult to maintain a uniform flow over the entire cross section. It is not sufficient because it requires a large amount of power to generate electricity and is expensive.

Therefore, as shown in FIGS. 8 to 9, a nozzle 10 for discharging water into the pool body 1 is attached to one end gA of the pool body 1, and a circulating water outlet 3 is installed at the other end of the pool body 1. A flowing water pool is provided in which a nozzle 10 and a circulating water outlet 3 are connected by a circulating hose 4, and water is spouted from the nozzle 10 into the pool body 1 by driving a pump 5 attached to the circulating hose 4. being developed. In this pool, the water spouted into the pool body 1 from the nozzle 10 generates a surface flow 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 straightening section 53 is also unnecessary, which is advantageous in terms of cost and installation location. However, because of the localized jet flow from the nozzle 10, the velocity distribution is too large, making it difficult for swimmers, especially beginners, and making it extremely difficult to adjust the flow velocity.

[Object of the Invention] The present invention has been made in view of the above points, and in addition to being able to save energy and save space for swimming with one trowel, the present invention allows water to flow into the pool with a uniform width. The purpose of the present invention is to provide a running water pool in which even beginners can easily swim.

[Disclosure of the Invention] That is, the flowing water pool according to the present invention includes a pool body 1
A water flow generator l that discharges water into the pool body 1 at one end of the! At the same time, a circulating water outlet 3 is provided at the other end of the pool body 1, and a circulating water outlet 3 is connected to the water flow generating device 2 and the circulating water outlet 3 with a circulating hose 4, and a pump 5 is attached to the circulating hose 4. 5, the water flow generation device 2 is connected to a nozzle header provided with a long slit nozzle 6 in the horizontal direction. 7, the nozzle header 7 is installed near the water surface of the pool body 1, and the slit nozzle 6 is connected to the pool body 1.
It is characterized by having a water inlet 8 that opens to the side and allows water to flow into the nozzle hair goo 7 at both ends of the nozzle hair goo 7, so that a flow is generated only on the surface of the water of the pool body 1, and the surface layer is By forming an iF, the power is reduced, and water is introduced into the nozzle header 7 from the water inlets 8 at both ends, and the water is ejected from the horizontally long slit nozzle 6. is made to flow uniformly into the pool body 1 in the width direction.

The present invention will be described in detail below based on examples. As shown in FIGS. 1 and 5, the pool body 1 is formed of concrete, a steel plate, an aluminum plate, or stainless steel, and the size of the pool body 1 is not limited, but for example, the width is 2.
2ffi, length 4.5m.

It can be formed with a water depth of 0.9 m and a volume of about 9 m'. A water flow generator 2 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 generating device 2 is comprised of a nozzle hair goo 7 formed in a cylindrical shape. As shown in FIGS. 2 to 4, an opening 11 with a width of about 5 to 10 mm that continues in the longitudinal direction is bored on the circumferential surface of the nozzle header 7, and an id protrusion 12 is protruded from the edge of the opening 11. A slit nozzle 6 is formed by opening the guide protrusion 12.12. The slit nozzles 6 are arranged in parallel in multiple rows above and below.

Also, fixing pieces 13 are provided at both ends of the puffer 7 to the nozzle, and a mounting hole 14 is bored in the fixing pieces 13. This nozzle header 7 is disposed within a recessed step 15 recessed in the end of the pool body 1, and is connected to an introduction pipe 16 fixed to the pool body 1. An O-ring 17 is interposed between the introduction pipe 16 and the mounting hole 14, and the nozzle header 7
is rotatably supported by the introduction tube 16. Furthermore, a rotation adjustment ratchet 18 that comes into contact with the side surface of the nozzle header 7 is provided at the end of the introduction pipe 16 .

Further, in front of the slit nozzle 6 in the nozzle header 7, a current plate 19 having a through hole is provided. In the figure, 20 is a header formed in a cylindrical shape, both ends of the header 20 are closed, and the header 20 is provided with two connection parts 22 and three connection parts 21.

On the other hand, a circulating water outlet 3 is provided at the other end of the pool body 1.
1! i&? It is connected to the connecting portion 21 of the header 20 with a circulation hose 4. A pump 5 is attached to each of the circulation hoses 4, and a water flow regulating valve 2 is attached to each of the circulation hoses 4.
3 is provided. And the connection ff of the header 20
1S22 and the introduction pipe 16 are connected by a 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 header 20 to the introduction pipe. It flows into the nozzle header 7 through 16 inlets 8 .

In this way, since the water flows in from the inlets 8, 8 on opposite sides of the nozzle header 7, the water is discharged from the slit nozzles 6 of the nozzle header 7 into the pool body 1 with a uniform width without being biased. Therefore, it is possible to attach a plurality of pumps 5 to the circulation hose 4 to send water in the circulation hose 4, and by using a small pump 5, it is possible to send water through the circulation hose 4. This eliminates the need to use , making it possible to reduce manufacturing costs. Further, as shown in FIG. 5, this nozzle header 7 is placed near the water surface in the pool body 1, and can direct flow only to the surface layer of the water in the pool body 1.
Therefore, by swimming against the surface current F, there is no need to flow the entire amount of water in the pool body 1 as in the past, and it is possible to reduce the power and enjoy swimming economically. . Here, the flow rate and flow velocity of the water can be adjusted using the regulating valve 23 provided on the circulation hose 4, or the flow velocity of the surface flow F can be increased or decreased by changing the direction of the slit nozzle 6. By balancing the resistance (flow velocity) of this water with the propulsive force (swimming speed) of the swimmer, the swimmer can be kept at a nearly constant position within the pool body 1. people can now swim while stopped;
This means that you can swim continuously, just like in a large swimming pool. In addition, the water ejected from the slit nozzle 6 spreads in layers on the ice surface, but by configuring two rows of slit nozzles 6 to eject water from each other, water can be spread on the ice surface. The ripples become smaller and the flow speed increases accordingly, making it possible to obtain smooth water flow. The connection between pump 5 and Hefugu-20 is shown in Figure 6 (
As shown in b), the circulation hose 4 from the pump 5 may be connected to one location of the header 20.

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 to the nozzle header 7. In addition, the return pipe 32
A heat exchanger 25 is connected to the pool body 1, and the water can be heated appropriately by fabricating a valve 30. Sao 711! The adjustment pipe 36 is an overflow port.

[Effects of the Invention] As described above, in the present invention, a nozzle header having a horizontally long slit nozzle is installed near the water surface of the pool body to discharge water into the pool body.
It can generate a surface flow in the pool water, so there is no need to flow the water throughout the pool, and less power is required for swimming.Furthermore, since it is a horizontally long slit nozzle, it can be used in the width direction of the pool. It is possible to obtain a surface flow with a substantially uniform velocity distribution, and even beginners can easily enjoy swimming. In addition, water inlets are provided at both ends of the nozzle header to allow water to flow into the nozzle and into the rudder, so even if multiple circulation hoses and nozzles are connected to the rudder, water can be discharged at a uniform flow rate into the pool body. Therefore, it is possible to attach a small pump to each circulation hose, and the cost for manufacturing a flowing pool can be reduced compared to the case where a large pump is attached.
