Abstract

PURPOSE: To make a pool possible to be operated with a pump of a relatively small capacity, to make a building lot area small, and to manufacture the pool in a compact shape, by providing plural pieces of jetting nozzles on a part lower than the partition plate of wall surface on the downstream side of a flow above the partition plate and providing a suction slit above the jetting nozzles further. CONSTITUTION: Water from the pump 37 is jetted from the nozzles 35 and returned to the pump 37 from the suction slit 36. Since a jet stream from the blow-off nozzles 35 is made to flow to the lower part of the partition plate 32, performs the function of a jet pump and forms a negative pressure in a nozzle downstream part, the water present at the upper part of the partition plate 32 is pulled in, turned as indicated by an arrow Rt along the wall surface 30a, made to flow as indicated by the arrow R1 at the lower part of the partition plate 32, turned again along the wall surface 30b on an opposite side, made to go out to the upper part of the partition plate 32 and made to flow at the upper part of the partition plate 32 as indicated by the arrow Ru and a vertical circulation flow is generated holding the partition plate 32 there between. A water amount flowing through a swimmable area 39 at the upper part of the partition plate becomes more than ten times of a flow rate blown out from the nozzles 35. Thus, by the pump of the relatively small capacity, the vertical circulation flow inside a pool main body is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an energy-saving, space-saving swimming pool for swimming training for people and animals.

Traditional Skills Swimming pools may be used for swimming training. At that time, it is common to form a flow by circulation, but if you try to circulate all of the fluid to be circulated, a large amount of power is required.

For example, in the vertical circulation pool 10 shown in FIG. 6, the entire amount is circulated as indicated by arrow H by the axial pump 1. This requires a large capacity trickle pump. In the figure, 2 indicates a rectifying section, and 6 indicates a swimming area.

FIG. 4 shows an example of a conventional circulating pool in which the flow circulates in the R direction in a plane.

In the illustrated example, the water 21 in the circulating pool 20 circulates in the R direction. This means that a portion of the flow is sucked through the suction pipe n and goes to the pump, from where it is blown in the flow direction by the blow pipe 23 to produce a flow in the R direction. Such planar circulating pools have the disadvantage that they require a large area for installation.

Means for Solving the Problems In this invention, in order to eliminate the conventional drawbacks, a partition plate that divides the depth into two is provided in the pool, and this partition plate and the pool wall surfaces on the upstream and downstream sides of the flow By providing an opening between each of the two, and by providing a plurality of jet nozzles below the partition plate on the downstream wall of the flow above the partition plate, and further providing a suction slit above the jet nozzle, the jet Due to the induced action of the jet from the nozzle, the flow above the partition plate is diverted downward along the upstream wall surface and flows in the opposite direction below the partition plate, creating a vertical circulation across the partition plate. This is the result of a vertical circulation pool.

Embodiment FIG. 1 is an explanatory diagram of a vertical circulation pool according to the present invention, in which water 61 is contained inside a pool body 60. A partition plate 62 that divides the depth into two is provided, and a wall surface 30a on the downstream side and a wall surface 3 on the upstream side in the flow direction Ru above the partition plate 52.
Openings 33 and 34 are provided between the partition plate 62 and the partition plate 62, respectively. A plurality of blowout nozzles 35 are provided below the partition plate 62 of the wall surface 30a, and a suction slit 66 is provided above the partition plate 62. The blow-off nozzle 65 and the suction slit 66 are connected by a pipe 68 via a pump 67, and the water from the pump 67 is jetted out from the nozzle 35, and only the jetted plate is returned to the Bonzoro 7 from the suction slit 66.

As described above, the jet from the blowout nozzle 65 flows below the partition plate 62, acts as a jet pump, and forms a negative pressure downstream of the nozzle, so the water above the partition plate 62 is drawn in. , move to the wall 30a and turn as shown by the arrow Rt, and move below the partition plate 62 by the arrow RI! It flows as follows, turns again along the opposite wall tfJ3υb, exits above the partition plate 62, flows above the partition plate 32 as indicated by the arrow Ru, and generates a vertical circulation across the partition plate 32.

The amount of water flowing through the swimmable area 69 above the partition plate is ten times or more the flow rate blown out from the nozzle 55. Therefore, it is possible to generate vertical circulation within the pool body using a relatively small capacity pump.

In 8g2 diagram (a), the central V indicates the velocity distribution,
The flow velocity in the swimmable area 69 is fastest at the water surface DW,
The flow slows down in the depth direction. Therefore, wasted energy loss in the deep part near the partition plate can be reduced.
Enables energy-saving operation.

Next, as shown in FIG. 2, by providing a slope 41 at the bottom of the wall surface 30b opposite to the nozzle installation wall surface 30a, the circulating flow R can be increased more effectively.

FIG. 2(b')K shows an example in which the slope 41' is a straight slope.

Furthermore, as shown in FIG.
The velocity distribution V within the swimmable area 59 can be made into any shape.

Effects The vertical circulation pool of this invention has the above-mentioned configuration and utilizes vertical circulation flow, so it can be operated with a relatively small-capacity pump, and the site area is small (can be made compact). It can be manufactured in any shape.
