Description

[Detailed Description of the Invention] [Technical Field] The present invention generates a water flow from one end of a small pool body, and swims against this water flow, thereby saving space and energy. This is about a flowing pool that can be enjoyed.

[Background technology] Swimming is a sport that many people engage in 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. The problem is that it requires 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, one example of such a small running water pool is one adapted from a circulating water tank 50 for hydraulic experiments on a ship. This is 2m wide, 1m deep,
A swimming part 51 with a length of about 5 m is provided in the water tank 50, and a propeller 5 for generating water flow is disposed in the water tank 50.
2 and the rectifier 53 to generate a water flow having a uniform cross section. In this case, a uniform flow is preferable for swimming, but in such a circulating water tank 50, the rectifier 5
3 is large, resulting in a large installation area, and in order to generate a uniform flow over the entire cross section, a large amount of power is required, resulting in high costs, which are not sufficient.

Therefore, as shown in FIGS. 8 to 9, a nozzle 10 for discharging water into the pool body 1 is attached to one end of the pool body 1.
A circulating water outlet 3 is provided at the other end of the nozzle 10.
A flowing water pool has been developed in which a circulating water outlet 3 is connected to a circulating water outlet 3 by a circulating hose 4, and water is spouted from a nozzle 10 into the pool body 1 by driving a pump 5 attached to the circulating hose 4. . In this pool, the water jetted 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 a large amount of water is caused to flow as shown in Fig. 7. Since this is no longer necessary, 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, 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 it is possible to swim in an energy-saving and space-saving manner, and also allows water to flow into the pool with a uniform width, making it easy for beginners to swim. The purpose of this project is to provide a flowing pool in which people can easily swim.

[Disclosure of the Invention] That is, the flowing water pool according to the present invention is provided with a water flow generating device 2 that discharges water into the pool body 1 at one end of the pool body 1, and at the other end of the pool body 1. A circulating water outlet 3 is provided at the water flow generating device 2, and the circulating water outlet is connected to the water flow generating device 2 with a circulating water hose 4, and a pump 5 is attached to the circulating hose 4, and the pump 5 is driven to supply water from the water flow generating device 2 to the pool body. 1, the water flow generation device 2 is composed of a nozzle header 7 provided with a horizontally long slit nozzle 6, and this nozzle header 7 is connected to the water surface of the pool body 1. The slit nozzle 6 is installed at a nearby position to open toward the pool body 1 side, and water inlets 8 are provided at both ends of the nozzle header 7 to allow water to flow into the nozzle header 7. By generating a flow only on the surface of the water to form a surface flow F, it is possible to reduce power, and the water is introduced into the nozzle header 7 from the water inlets 8 at both ends, making it longer in the lateral direction. By jetting water from the slit nozzle 6, the water flows uniformly into the pool body 1 in the width direction.

The present invention will be described in detail below based on examples. 1st
As shown in the figure and FIG. 5, the pool body 1 is formed of concrete or a metal plate such as an iron plate, an aluminum plate, or a stainless steel plate, or a synthetic resin plate such as FRP, and the size of the pool body 1 is not limited. No, but for example, width 2.2m, length 4.5m, depth
It can be formed with a length of 0.9m and a capacity of about ^9m3 .
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 provided at the other end of the pool body 1. The water flow generator 2 includes a nozzle header 7 formed in a cylindrical shape. As shown in FIGS. 2 to 4, a longitudinally continuous opening 11 with a width of about 5 to 10 mm is provided on the circumferential surface of the nozzle header 7, and a guide protrusion 12 is provided protruding from the edge of the opening 11. A slit nozzle 6 is formed between the guide protrusions 12, 12. The slit nozzles 6 may be arranged in parallel in a plurality of vertical rows. Further, fixing pieces 13 are provided at both ends of the sozzle header 7, and mounting holes 14 are formed in the fixing pieces 13. The nozzle header 7 is disposed in a recessed step 15 formed in the end of the pool body 1, and an introduction pipe 16 fixed to the pool body 1 is inserted into the attachment hole 14 of the nozzle header 7. An O-ring 17 is interposed between the introduction pipe 16 and the attachment hole 14, and the nozzle header 7 is rotatably supported by the introduction pipe 16. Further, 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. Also,
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 has two connection parts 22 and three connection parts 2.
1 is provided.

On the other hand, three circulating water outlets 3 are provided at the other end of the pool body 1, and are connected to a connecting portion 21 of the header 20 by a circulating hose 4. A pump 5 is attached to each of the circulation hoses 4, and a water flow regulating valve 23 is also provided. The connecting portion 22 of the header 20 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 enters the header 20.
The introduction pipe 1 is passed through the hose 24 from the connection part 22 of 0.
6 flows into the nozzle header 7 from the inlet 8. In this way, since water flows in from the inlets 8, 8 on opposite sides of the nozzle header 7, the water is discharged from the slit nozzle 6 of the nozzle header 7 into the pool body 1 with a uniform width without being biased. Therefore, it is possible to send water in the circulation hose 4 by attaching a plurality of pumps 5 to the circulation hose 4, and by using a small pump 5, it is possible to use a large pump 5 as in the past. This eliminates the need for this, and the manufacturing cost can be reduced. Also, this nozzle header 7 is the fifth nozzle header.
As shown in the figure, it is placed near the water surface in the pool body 1, and allows flow to flow only to the surface layer of the water in the pool body 1, so that the water swims against the surface flow F. Therefore, it is no longer necessary to flow the entire amount of water in the pool body 1 as in the past, and the pool can be enjoyed economically by lowering the power. Here, the flow rate and flow velocity of water can be adjusted using the regulating valve 23 provided on the circulation hose 4, or the direction of the slit nozzle 6 can be changed to allow the surface flow F.
It is possible to increase or decrease the flow velocity of the swimmer, and to change the force with which the swimmer is swept away by the water flow, and to balance this water resistance (flow velocity) with the swimmer's propulsive force (swimming speed). If you match it,
The swimmer can swim while stopping at a substantially constant position within the pool body 1, and can swim continuously as in a large pool. In addition, the water ejected from the slit nozzle 6 forms a layer on the water surface and spreads,
In particular, by configuring water to be ejected from two rows of slit nozzles 6, the ripples on the water surface are reduced, the flow velocity is increased, and a smooth water flow can be obtained. The pump 5 and the header 20 may be connected to each other by connecting the circulation hose 4 from the pump 5 to one location of the header 20, as shown in FIG. 6b.

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 filtered water outlet 28 provided at the end of the pool body 1 are connected by a hose 29,
Further, the filtration pump 27 of the filtration 26 is connected to a five-way valve 30 and a sand filter 31, respectively, so that the filtered water is returned to the nozzle header 7. Further, a heat exchanger 25 is connected to the return pipe 32, and the water is appropriately heated by operating a valve 30. 34 in the diagram

[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 is possible to generate current, there is no need to flow the water throughout the pool, and there is a device that requires less power when swimming, and since it is a horizontally long slit nozzle, the speed is almost constant in the width direction of the pool. It is possible to obtain a surface flow with a uniform distribution, and even beginners can easily enjoy swimming. Also,
Since water inlets are provided at both ends of the nozzle header to allow water to flow into the nozzle header, water can be discharged at a uniform flow rate into the pool body even if multiple circulation hoses are connected to the nozzle header. Therefore, it is possible to attach a small pump to each circulation hose, and the manufacturing cost of the flowing pool can be reduced compared to the case where a large pump is attached.
