を設The present invention relates to a circulating water tank device for swimming practice that allows swimmers to swim while remaining in one spot, and more specifically, the present invention relates to a circulating water tank device for swimming practice that allows swimmers to swim while remaining in one spot. There is a type of circulating water tank device. Recently, 'C/
However, in the currently used instruction on swimming strengthening training, noom correction, swimming method research, etc., instruction 1 is held at the poolside. In some facilities, the swimmers can be seen from the uphill side of the pool, or, depending on the facility, the swimmers can be guided by looking at the swimmer's side or toe through a viewing window installed on the underwater side wall of the pool.
4-It goes without saying that it is difficult to analyze and teach the swimmers, but the biggest problem here is that at least the bfli observer (instructor) has to walk along the poolside with the swimmers, which is cumbersome. ing. In addition, nearby, in order to cover up the defect described in F, a recirculation water tank for swimming has been experimentally developed (manufactured by the applicant), which allows the water to flow so that the swimming hole essentially stays in one place. There is. However, since this recirculation water tank is an experimental water tank for the purpose of making various measurements, it has a completely different tank structure from the m-tier general pool. For this reason, the narrow swimming path is not only deserted, but also far from an environment in which one can swim comfortably without feeling mentally safe. Furthermore, this recirculating water tank uses a vertical circulating water flow system, so the entire tank is 211i! This structure required a solid structure down to the foundation, which increased manufacturing costs and made it difficult to use as a general water tank. The present invention was completed in view of the above-mentioned circumstances, noting that it would be a benefit to everyone in the art if the recirculation water tank were to become a simple facility that could be incorporated into the main body of a general I-ru. In other words, the present invention defines the circulation waterway as a horizontal circulation type, and also constructs a swimming path section that is at least an open waterway by dividing a part of a general swimming pool facility, thereby creating a swimming path that is free from mental stress. This is a water flow tank device for swimming practice. Hereinafter, the present invention will be explained based on the drawings of one embodiment as follows. 1 is 50n+, 25+n nol etc.+7) -M (7)

The recirculation side body 4a, which becomes the closed waterway 4 inside, is installed at the 1-face position of the pool side b, and is placed in front of the flowing water nozzle part 2 at least 1-]-s. A swimming path section 7, which becomes an open water channel 6, is formed by partitioning the swimming path section 7 with a removable partition member 5 with a width of .degree. 8, and the other end of the recirculation side body 4a faces the suction port 8, forming a horizontal circulation type recirculation water tank 3 in which the water channel as a whole has a horizontal frame. 9 is a flow propeller installed at the base of the diffuser part 48' of the recirculation heating body 4a,
The flow propeller 9 has an axial pump type rotation mechanism and its rotation can be controlled by a variable speed motor 10 disposed outside. 11 is a water nozzle 11 part 2 and a suction port part 8
A rectifying member serving as a rectifying grid installed in [ ), the rectifying member 11
are installed diagonally in each coop part 3a of the recirculating water tank 3 to make the flow velocity distribution uniform between the biased current 12 and the flow velocity distribution in the C swimming path section 7. Reference numeral 13 denotes a safety net stretched across the a-end of the swimming path section 7, and the whole constitutes a circulating water tank device 114 for swimming #lR11. One way to remove the cut-out portion 445 that partitions the pool body 1 is to attach a locking member 15 (such as a 1° eye bolt) to the side wall 1a that forms the edge of the flowing water nozzle mouth portion 2. Then, branch receiving fittings 16 are buried at appropriate intervals in the bottom surface 1C of the pool body 1, which is the mounting axis F of the locking fittings 15, and hooks at the end of the partition membrane 5' are provided with tensioned cable ears 17 serving as the bottom material. The part 18 is locked to the first metal fitting 15,
The partition membrane body 5' is expanded parallel to the side wall 1b, and the middle part of the partition is fixed to the support pillar 19 that has been installed in the metal fitting 16 in advance.
The tip is engaged with the engaging 1F metal fitting 15 of the suction port 8 to cut the hand pool body 1. Also, it is necessary to arrange a bias *all 12 on the bent part 58 of the partition part 85 which is the end of the open water channel 6, but at this time, an appropriate number of bias currents w412 are supported by protruding from the L-side b side. - The support provided on the bottom surface 10 (φF) of the frame 20 is referred to as a reinforced support structure provided on the metal fitting 16.Moreover, there may be a plurality of flow propenos 9.To explain this function, first. This circulation water tank device i!
The swimming path section 7 of 114 utilizes the side part of the dark C pool body 1. For this purpose, a roll-shaped partition membrane 5' is developed along the branch 19 on the side of the pool body 1.
The C corner of the pool body 1 is partitioned off to form a swimming path section 7 of an open water channel 6 which becomes a part of the circulating water tank 3. Here, Ht! When the flow propeller 9 is rotated by a variable speed motor driven by 1°, the accelerated water flow passes through the recirculation heating body 4a and is given a constant flow velocity from the water nozzle opening 2 on the side wall 1a of the pool body 1. The water flows out into the swimming path section 7, forming a horizontal circulation waterway as a whole. In this state, swimmer B is in the swimming path section 7, which becomes part of the axis of the /-le.
It is something that enters the water and swims towards this water current (swimming against the water current). In this case, if the swimming speed and the water flow speed are equal, the swimming WB remains at a certain point in the swimming path section 7. Therefore, during swimming strengthening training, the swimming method (form) is monitored either from the poolside b or through the viewing window 21 formed on the side wall 1b of the pool body 1 that is underwater and made of a transparent material such as glass. This allows for easy form correction and swimming instruction. Of course, this water flow can be freely changed by selecting the rotation speed of the flow pump I copella 9 (0 to 2.5 R+ per second). Moreover, the recirculating water jetted through the water nozzle opening 2, which becomes a contracted flow, is controlled by a rectifying member 11 made of a rectifying grid, punched metal, etc. at the outlet, and a plurality of arcuate plates formed on each cop part 3a. Since it is equipped with two axial flow blades 12, the water flow is arranged and the flow velocity distribution is made equal, so that a state of swimming on a stationary water surface (ordinary pool surface) is obtained. Suppose that swimmer IB gets tired of swimming and is swept away by the current.
Also, since the safety net 13 is stretched at the end of the swimming path section 7, you can swim with peace of mind by holding it on the suction port 8 side. An emergency stop limit switch (f, not shown) is provided to stop the flow propeller 9 when a load is applied to it. The swimming path section is formed as a part of the pool body, and a flow propeller connected to the open waterway that becomes the swimming path section is distributed, and a closed channel that becomes the circulating operation engine section is combined in a planar manner to create a so-called horizontal structure. By using a circulating water tank configuration, the installation space is relatively large, but even if the structure itself is simple, it can be used in one minute.
It can be provided at a lower cost than the vertical circulation water flow system, and is easier to maintain and manage. Moreover, the best white swimsuit of the present invention incorporates this swimming path into the main body of the l-le, so you can swim in exactly the same environment as usual, and it does not cause any mental strain. Of course, it is also possible to configure it as part of an existing Knoll facility. Historically, this water flow was produced using a variable-type propeller, so that a flow velocity was obtained that corresponded to the speed of the swimmer, and this water flow itself was regulated by flow regulating members, flow blades, etc., so that a uniform flow velocity distribution was achieved. There are some that have effects such as being able to swim without glare.
