Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pool with a circulating water tank in which a part of the pool body is a part of the circulating water tank.

Conventionally, a commonly used pool is a so-called still water type aquarium, which is simply a pool tank filled with water. For this reason, during swimming practice, the only thing left to do is turn and swim several times, and when it comes to strengthening the swimmer's swimming or giving guidance on correcting form, at least an instructor must walk along the poolside with the swimmer. Therefore, they are forced to adopt an inefficient teaching method.

Also, in recent years, so-called flowing pools have appeared as swimming pools, but it is not possible to carry out swimming strengthening training in these pools (of course, in this type of pool, the speed of the flowing water cannot be adjusted freely). (impossible to change), the emergence of a swimming pool with a circulating water tank is desired.

The present invention was developed in view of the above circumstances, and focused on the fact that if one corner of an ordinary pool could be used as a circulating water tank, it would provide great benefits to those skilled in the art without having to create a circulating water tank exclusively for training. be.

That is, the present invention installs the main body of the circulation water tank (a closed channel equipped with a flow propeller), which serves as the water flow engine, on the lower surface of the pool side, which is generally a space (dead space for equipment installation), and the circulation tunnel body. Both ends of the main body part facing the water nozzle mouth and suction mouth part provided on the side wall which becomes the corner part of the pool body, and the corner part of the pool body part is partitioned with a partition member to form an open channel, and the open water A waterway and a closed waterway form a horizontal circulation type recirculation tank, and this open waterway is used as a swimming channel.

Hereinafter, the present invention will be explained with reference to drawings of embodiments.

Reference numeral 1 denotes a pool body, and a circulation cavity body 6, which serves as a closed waterway 5 equipped with a flow propeller 4 in a diff user part 3, is installed on the lower surface of the pool side 2, and one end of the circulation cavity body 6, which becomes the flow side. is connected to a running water nozzle port 7 provided on the side wall 1a of the corner a of the pool body 1, and the other end is connected to a suction port 8 provided on the other side wall 1b. A partition member engaging fitting 9 is attached to the mouth edges of the water nozzle opening 7 and the suction opening 8, and the partition member 10, which serves as a membrane connected to the engaging fitting 9, is spaced at a predetermined distance from the side wall 1b. The corner part a of the pool body 1 is partitioned into a swimming path course by extending the swimming pool at a position between the pool body 1 and the pool body 1. In this case, the partitioning position of the partitioning member 10 is arranged at a location separated by at least one course width from the side wall 1b. Further, in the middle of this partition member 10, a plurality of support columns 1 are installed from the pool bottom 1c.
1 and partially fixed. The distal end of the partition member 10 is bent to face the mouth edge of the suction port 8 via the bending guide column 11', and the engagement fitting 9 similar to the above is attached.
Lock it by holding it. The inner side divided by the partition member 10 is an open water channel 13 which becomes the swimming path section 12, and the open water channel 13 and the closed water channel 5 form a horizontal circulation type recirculation water tank 14. 15 is a rectifier made of a grid, punched metal, etc. attached to the water nozzle opening 7; 16 is a safety net stretched at the rear end of the swimming path 12 on the suction port 8 side; 17 is a frame-shaped circuit as a whole. The four corner parts 14 of the circulating water tank 14
The deflection wing 17 is formed by combining a plurality of arc-shaped plates. Also, open waterway 1
Since the corner portion 14a in 3 has an assembled configuration in which the open water channel 13 itself has the partition member 10,
The deflection blade 17 has a support arm 18 protruding from the pool side 2 side and a receiving metal fitting 19 arranged on the pool bottom 1c.
Secure by engaging the top and bottom ends.

To explain this function now, first of all, when this pool body 1 is used for normal swimming pool use, the pool body 1 will not be partitioned unless a removable partition member 10 is placed in the corner. Since the swimming path section 12 is not configured, a predetermined pool can be created without any problems.

Here, when the pool water is flowing and the swimmer wants to practice while remaining in one place, for example, for strength training, form correction, swimming method research, etc.
A hook member 20 provided at one end of the partition member 10 of the membrane body is hung on an engaging metal fitting 9 made of an eye bolt or the like arranged on the edge of the water nozzle opening 7 provided on the side wall 1a, and the partition member 10 is fixedly fixed from the side wall 1b. The pool body 1 can be attached to the side wall 1b by tensioning them at intervals (positions separated by at least one course) and securing the ends to the engagement fittings 9 protruding from the mouth edge of the suction port 8 of the side wall 1b. A swimming path section 12 is formed by dividing a certain width along the partition member 10, and an open water channel 13 is formed inside the partition member 10. Of course, the water in the pool body 1 also fills the closed waterway 5 through the water nozzle opening 7 and the suction opening 8. Note that since the reinforcing wire 21 is laid in the partition member 10, the partition member 10 does not bend even if a water flow occurs in the open channel 13 portion.

Next, swimming in the swimming path section 12 in this state is as follows:
If the sending propeller 4 located in the closed channel 5 section is rotated by the drive of the variable speed motor 22 attached to the sending propeller 4, the water flow A accelerated by the sending propeller 4 will flow through the closed channel. 5, the water flows through the flowing water nozzle opening 7 to the side of the swimming path section 12 which becomes the open water channel 13, and circulates throughout the circulating water tank 14.

After that, swimmer B enters the swimming path section 12 and swims toward this water flow A (swims against the water flow).At this time, if the swimming speed and the water flow speed are equal, swimmer B can remain at a fixed location in the swimming path section 12. Therefore, the instructor can instruct the form from a fixed position. Of course, the side wall 1 of the pool body 1 which becomes this swimming path section 12
If a viewing window 23 made of a transparent member such as glass is formed in a, the side or bottom surface of the swimmer B can be monitored through the viewing window 23.

In this case, the water flow A in the swimming path section 12 is created by disposing a rectifying device 15 at the flowing water nozzle mouth section 7 and disposing deflection blades 17 at each corner section 14a.
The water flow is arranged and the flow velocity distribution is equal, making it appear as if you are swimming on the surface of still water, which is suitable for prescribed instruction or strengthening training.

Furthermore, even if swimmer B gets tired of swimming and gets swept away by the water current A, there is a safety net 1 at the rear end of the swimming path section 12.
6, there is no risk that the swimmer B will be sucked into the suction port 8. In this case, the safety net 16
The section is equipped with an emergency stop limit switch (not shown) that stops the drive of the flow propeller 4 when an unnecessarily large load is applied.

FIG. 5 shows another embodiment of the swimming path section. In this case, the swimming path section 12 divided into the pool body 1 is configured to fill the width of the pool body 1 (if necessary, the entire length of one course may be used as the swimming path section). . That is, in this case, the running water nozzle opening 7 and the suction opening 8, which are the opposite end positions of the closed water channel 5 disposed on the lower surface of the pool side 2, are installed on opposite side walls, and the running water nozzle opening 7 and the suction opening 8 are connected to each other in the same manner as described above. If the mouth portions 8 are partitioned by tensioning the partition member 10, one side of the pool body 1 is partitioned, and a long swimming path portion 12 that becomes an open waterway 13 is formed, and the closed waterway 5
This creates a horizontal circulation type recirculation water tank 14. In such a long swimming path section 12, two or three swimmers can swim at once. Also, at this time, swimming path section 1
2, rectifiers 15 are arranged at regular intervals,
The flow velocity distribution in each divided swimming path section 12 is made uniform.

As described above, the swimming pool with a circulating water tank of the present invention divides the pool body into an open waterway by disposing a removable partition member (membrane body, wall body, etc.) at the corner of the pool body (for example, near the diving board). In addition to creating a swimming path section,
By connecting the closed water channel end, in which flow propellers are arranged in parallel on the lower surface of the pool side, to the flowing water nozzle mouth and suction port of the side wall, which are both ends of the open water channel, a horizontal circulation type recirculation water tank is constructed. Only when using a circulating water tank, a part of the pool can be divided into a circulating swimming path, and swimming exercises can be performed while staying in a certain spot, so it can be used not only for strengthening training, but also for observing form, corrective instruction, and swimming techniques. The instructions themselves are easy to follow. Of course, this swimming path section is only used as a part of the pool, so it becomes an environment where you can swim comfortably just like in a normal pool practice. In addition, the good thing about this circulation water tank pool is that the closed waterway that serves as the circulation operation mechanism is built into the lower surface of the poolside, which creates a space, so there is no need to secure a special installation space (it can be used in any pool facility, The poolside area is used for space purposes), making it an economical land use, and since the entire recirculation water tank uses a horizontal circulation system, the structure is simple and can be manufactured at low cost, and maintenance is relatively low. It's easy. Moreover, since the recirculation operation engine section is installed underground at the poolside and is separated from the pool body, no noise is transmitted to the swimmers, which also provides the effect of allowing swimmers to swim with peace of mind.
