    SWIMMING POOL WITH WATER CIRCULATION SYSTEM
    The present invention relates to a training pool, in particular a swimming training pool with a water circulation system.
    Hereby, a reference to a patent document or other subject that is given as a prior art should not be considered as an admission that this document or subject was known or that the information contained therein form part of the general knowledge on the priority date of any one of the claims.
    Training pool manufacturers have dedicated themselves to developing a relatively smaller training pool / athletic / physiotherapy training pool or rehabilitation training, in response to increasing demand for training. aquatic reeducation, and a restriction of standard pools that occupy a large area, and the like. Such swimming pools generally adopt an axial flow pump which uses a rotor with vanes which direct the flow axially.
    Chinese patent application CN 103206100 A discloses a fluid steering device or a water pushing device used for a swimming pool, comprising a pool body to which a pipe is connected, a water inlet at the pool level is configured at one end of the pipe, and a water outlet is disposed at the other end of the pipe; an axial flow pump, which is connected to a motor, is installed on the pipe, a flow direction device being disposed on the water outlet. In addition, the flow direction device is a cell flow direction device formed by the combination of a plurality of tubes having the same length, or a cellular component having a plurality of holes; the tubes can be adhered to each other, and the flow direction device is adapted to the pipe.
    Chinese patent CN 202611285 U discloses a water push device for a water circulation pool, comprising a pool body and a water tank disposed in the lower part of the pool body. The bottom of the water tank is in fluid communication with the bottom portion of the pool body, an axial flow pump is mounted between an upper portion of the water tank and an upper portion of the pool body, that is, i.e. an outlet end of the axial flow pump is connected to the pool body via an upper flange and the inlet end of the axial flow pump is connected to the water tank by the intermediate of a lower flange; a motor drives the axial flow pump by means of a coupling.
    US Patent Application 20100058528 A1 discloses an apparatus for generating a current in a swimming pool, comprising: a) a hull comprising an upwardly extending inlet chamber, in fluid communication with the pool, the intake chamber having a liquid inlet zone located in a lower end of the inlet chamber; b) an axial pump having an upstream suction side and a downstream discharge side, the pump having guide means arranged to cause a liquid to flow longitudinally in the discharge side channel substantially without swirling, the guide means being located downstream of the pumping element, and c) driving means arranged to drive the drive shaft, the driving of the drive shaft producing a liquid discharge through the discharge side outlet, to create a running in the swimming pool against which the swimmer is swimming.
    However, for example, in the tug experiment, if the tug and the towed vessel have an inadequate short distance between them, the water pushed by a tug rotor will impact the tug, whereby a backward force is generated in the water and towing efficiency is reduced. Similarly, the mentioned pool has such a disadvantage that since the pool has a relatively short length, the flow of water from a front end of the pool can be pushed backwards. by a rear end thereof, so that the thrust of the axial pump is countered. Thus, the actual water flow is less than a predetermined value that is set by the user using a switch.
    Therefore, it would be desirable to provide a training pool with a water circulation system to alleviate the problems described above, for example, so that the pool can provide unobstructed water flow. without bubbles and provide the user with a desired flow of water and a desired water speed.

    The present invention has the following advantages over the prior art: (1) In the present invention, the axial flow pump is operated to generate a powerful flow of water, the user can swim against the water flow in a small training pool that can be constructed without requiring a large area; (2) the present invention provides a more stable, bubble-free, powerful water flow so that a trainer outside the pool can clearly see swimmer movements and thus provide better guidance; (3) the variable frequency motor can provide variable flow / water speed, to suit the needs of the user.
    To better illustrate the object of the present invention will be described below, by way of illustration and not limited to, a particular embodiment, with reference to the accompanying drawing.
    In this drawing: Figure 1 is a perspective view of a drive pool according to the present invention; Figure 2 is a perspective view of the drive pool shown in Figure 1 rotated horizontally 180 degrees; Figure 3 is a schematic top view of the drive pool shown in Figure 1; Figure 4 is a schematic side view of the drive pool shown in Figure 1; Figure 5 is a schematic view of an overflow weir according to the present invention; and Figure 6 is an explosive view of an axial flow pump according to the present invention.
    In the following description, identical parts and positions will be numbered with the same reference numerals. All parts and positions shown in a specific figure will not necessarily be detailed in conjunction with this figure.
    Figures 1 to 4 show an embodiment of the present invention.
    Referring to Figure 1, it can be seen that a drive pool according to the present invention comprises a pool body 1 having a dimension of 5 m (length) x 2.5 m (width) x 1 , 5 m (height). A depth of water is approximately 1.3 m when the pool is used. A water tank 6 is configured in front of the front end F of the body 1. The axial flow pump 2 is configured above the water tank 6 and fluidly connected to the pool body 1 and to the water tank 6 , a powerful flow of water being injected into the pool due to the high speed rotation of a rotor of the axial flow pump 2 so that the user can swim / train in the pool, against the 'water flow. An upper inner side of a rear end R of the body 1 is a vertical plane in which a discharge opening 5 is configured, preferably the discharge opening 5 is defined at a vertical center line of the plane. A number of delivery pipes 10 are connected to the discharge opening 5, while the other ends of the discharge pipes 10 are connected to the water tank 6 or to a return water outlet 4. In this mode of In the embodiment, there are two delivery pipes 10 along both sides of the bottom of the body 1, respectively. A platform, extending from the plane, is located under the discharge opening 5, and a front side of the platform facing the front end of the body 1 is configured as a slope. Two seats, along the inner side of the rear end R of the body 1, are provided on both sides of the discharge opening 5 and the platform. A variable frequency switch 7 is located at the top of the body 1 to adjust the water speed applying to the user.
    Figure 2 is a perspective view of the training pool after horizontal rotation of 180 degrees, and Figure 3 is a top view of the training pool. A water inlet 3, connected to the axial flow pump 2, is configured at an upper inner side of a front end F of the body 1, and a water return outlet 4, connected to the water reservoir. 6, is configured at a lower inner side of the front end F of the body 1, preferably the inlet 3 and the outlet 4 are defined at a vertical center line of the front end F, and even more preferably, the inlet 3 and the discharge opening 5 are horizontally aligned with one another and have the same width. In the inlet 3, a laminar flow fountain technology is adopted, that is to say that water passes through a certain material (not shown), such as a sponge element, in which the bubbles in the water are compressed by a plurality of fine and irregular passages, whereby a bubble-free flow of water can be generated, so that a trainer outside the pool can observe the movements of swimming the user in a clear way and provide better guidance. In this embodiment, since the centers of the water inlet 3 and the discharge opening 5 are aligned with each other horizontally, so that at least a part of the water from the inlet 3 can flow into the discharge opening 5 and then into the discharge pipes 10 directly, a part of the reverse force on the water, which can be caused by an inner surface of the end rear R, is eliminated. Preferably, an area of the return water outlet 4 is three times an area of the water inlet 3, which makes it possible to guarantee that the flow of water pushed back by the platform and the seats can be sucked easily into the water tank 6 via the water return outlet 4.
    As shown in FIGS. 4 and 5, two overflow weirs 8, a length of which corresponds approximately to the length of the body 1, are provided at the upper part of the two inner sides of the body 1, preventing the water stirred by the swimmer from overflow outward. Each overflow weir 8 comprises a plurality of grids and outlets 11 configured at regular intervals, each outlet 11 being connected to a vertical pipe 9 while the other ends of the pipes 9 are connected to the discharge pipes 10.
    As shown in FIG. 6, the axial flow pump 2 comprises a motor 12 which is a variable frequency motor, an upper connector 13, an insulation connector 14, an insulation washer 15, a lower connector 16, a shaft 17 and a rotor 18. The isolation connector 14 can prevent water from coming into contact with electricity and thus eliminates the risk of electric shock. The axial flow pump 2 also comprises a pipe connected to the water tank 6, the shaft 17 and the rotor 18 being configured inside the pipe.
    During use of the drive pool, as shown in Figure 3, a strong water flow is injected into the pool due to the high speed rotation of the rotor 18. Before the water reaches the pool, the water should pass through the sponge (not shown) configured inside the water inlet 3, whereby the bubbles in the water flow are substantially eliminated, and the flow water, with a relatively large cross section, is injected out of the inlet 3 stably. Therefore, the training pool provides a uniform and powerful water flow A, whereby the user can swim / train, walk against the flow of water A. When the water flow A advancing towards the rear end R of the body 1, a portion B of the water of the water flow A remains adjacent to the surface of the water, then flows into the discharge pipes 10 via of the discharge opening 5, and finally returns to the water tank 6; the remainder C of the water of the water flow A can return to the rear when it strikes the rear end R of the body 1, then flows down along the front lateral surface of the platform and seats when it reaches them, and flows back to the front end F of the body 1, and finally enters the water tank 6 via the return water outlet 4. Thus, double water circulations - through the discharge opening 5 and the water return outlet 4, respectively - are formed. Then, the water inside the water tank 6 is injected back into the drive pool, by means of the rotation of the rotor 18. In addition, the user / trainer can use the switch 7 to adjust an output of the variable frequency motor 12 to obtain a desired water flow. In addition, the water stirred by the swimmer can enter the weirs 8 provided at the upper part of the two inner sides of the body 1, then return to the water tank 6 through the outlets 11, the pipes 9 and the discharge pipes 10. This arrangement prevents water inside the pool from overflowing out.
    It should be understood that the embodiment described above is merely a preferred embodiment of the present invention and is not intended to restrict or limit the invention. It will be apparent to those skilled in the art that obvious non-substantial improvements or modifications can be made without departing from the scope of the present invention.
    Throughout the description and claims of this application, the term "understand" and variations thereof, such as "comprising" and "includes", are not intended to exclude other features, components, whole numbers or steps.
