Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF THE INVENTION The present invention relates to a water flow rate regulating pool in which the water flow rate within the pool can be adjusted in accordance with the ability of swimmers.

Prior Art Conventionally used pools require a certain size for exercise, so with the exception of some personal pools, they are large and land acquisition costs are high.

Particularly with large pools, in order to make the pool warm enough for swimming in the winter, it would require building and equipment to cover the entire pool, as well as heating costs, making it impossible to use the pool at a low cost.

Furthermore, in the small personal pools mentioned above, it is not possible to enjoy sufficient exercise, and as a result, the use is limited to sunbathing during the warm season.

Purpose of the Invention Therefore, the present invention is a compact device that can adjust the water flow according to the swimming speed of the swimmer, does not take up much space, allows the swimmer to enjoy swimming according to the exercise ability of the swimmer, and is applicable to competitive swimming practice and rehabilitation. The purpose of the present invention is to provide a water flow rate adjusting pool that can be used as a water flow rate control pool.

Structure of the Invention According to the water flow rate adjusting pool according to the present invention, the pool is provided with a water outlet and a water intake, a water flow is generated by a pump connected to both of these ports, and a position detector installed in the pool is used to detect swimmers. The present invention is characterized in that it includes a control device configured to detect the position of the swimmer, operate the pump, and adjust the water flow speed in the pool in accordance with the movement of the swimmer.

EXAMPLES The present invention will be explained below with reference to illustrated examples of the present invention. As shown in the attached schematic diagram of the embodiment of the present invention, a water intake port A and a discharge port B are formed at both longitudinal ends of the waterway type pool 1. A main line 11 equipped with a pump 3 connects the water inlet A to the outlet B of this pool 1.
By operating the pump 3, it is possible to circulate water through the main line 11 and cause a water flow from the discharge port B in the pool 1 to the suction (3) water port A side.

The pool 1 is also provided with a sub-line 12 that branches off from the main line 11 and includes a pump 3, a purifier 7, and a water temperature regulator 8.

A purifier 7 provided in this sub-line 12 filters water using a filter and activated carbon, and a water temperature regulator 8 is configured to heat the water as required. This sub-line 12 uses a pump 31 to constantly circulate water within the sub-line 12 to filter the water in the pool and adjust the water temperature. The water flow is about 1/10 to 1/20. Therefore, it can be treated as having almost no influence on any amount of water flow adjustment in the main line 11, which will be described in detail later.

In addition, in front of the water intake port A and the discharge port B in the pool 1, there is a mesh-shaped rectifying plate 2 extending in the width direction of the pool 1.
2 is provided. These rectifying plates 2, 2 are the water intake port A.
(4) and appropriately diffuses and rectifies the water flow discharged from the discharge port B to create a substantially uniform water flow from the discharge port B to the water intake port A of the pool 1. .

Furthermore, position detectors 4, 5°6 are provided at six points in the longitudinal direction that define a predetermined section between the water intake port A and the discharge port B. These position detectors 4.5.6 each have a detection end 4°51,6 mounted above the water surface in the longitudinal direction of the pool 1.
It is equipped with +. These position detection ends 41.51, 6
1 is an improved version of the photoelectric switch used in automatic doors, etc., and can detect objects up to 20 degrees below the water surface.

The intervals between these detection ends 4° and 5゛ and 5' and 6'' are formed to the length of the standard swimmer's height plus a predetermined allowance, and these detection ends 41.sl, 61. When a swimmer is located within the section provided with the swimmer, at least one detection end 4°, 5° or 6" is activated to detect the position of the swimmer. In addition, a water velocity meter 10 is placed at a predetermined position base ζ in the section where the detection ends 41, 5°, and 61 are provided, and the detection end 101 installed underwater It is possible to detect the velocity of flowing water in the provided section.

In addition, this embodiment is equipped with a control device 9 consisting of an arithmetic device with a built-in program, and a position detector 4,
5.6 and the detected value of the flow velocity meter 10 are input, and after processing the detected value according to a predetermined algorithm, an appropriate command signal is sent to the pump 3 to operate it.

Further, the pump 61 of the sub-line 12 is also controlled by a separate control device 9.

In the above-described configuration, a swimmer can access the water outlet B from the water intake port A side.
When the swimmer starts swimming toward the side, the detection end 41 first detects the swimmer. Therefore, the control device 9 operates the pump 3 to generate a predetermined water flow within the pool 1. Here, if the swimming speed of the swimmer and the speed of the water flow are approximately equal, the swimmer will continue to be detected by either one or both of the detection ends 41, 51, and the control device 9 will detect the water flow. The pump 3 is driven and controlled so as to maintain .

Further, when the swimmer's swimming speed exceeds the water flow speed in the pool 1, the swimmer moves further toward the discharge port B side and is detected by the detection end 61 from the detection end 5''.

Therefore, the control device 9 increases the amount of water discharged by the pump 3 stepwise or continuously, and controls the pump 6 so that the water flow speed in the pool 1 exceeds the swimming speed of the swimmer.

Conversely, when the swimmer's swimming speed is lower than the water flow speed in the pool 1, the swimmer is swept away by the water flow and approaches the water intake port A side, and is detected by the detection end 5" to 41. Here,
The control device 9 controls the pump 6 to reduce the amount of water discharged by the pump 3 stepwise or continuously until the swimming speed of the swimmer exceeds the water flow speed in the pool 1.

By repeating the above operations, the swimmer can roughly reach the detection end 41.5 of the position detector 4.5. You will continue swimming in the section where the SL is installed.

Here, if the swimmer is detected at the detection edge 4°ζ, if it is detected at the detection edge 41, sl, if it is detected at the detection edge 51, it is detected at the detection edge 5°, 6'l. When the water flow is detected at the detection end 6', the water flow velocity is varied at each point in time when the water flow is detected at the detection end 6'. The pump 5 can also be controlled so that the water flow is at an intermediate speed when the detection end 61 detects the water flow, and the water flow is at the highest speed when the detection end 61 detects the water flow.

In addition, a signal indicating the water flow speed in the pool 1 is inputted into the control device 9 from the flow velocity meter 6, and the distance swam by the swimmer within a given time can be determined by integration.

In this embodiment, the six detection ends 41, 51, and 6+ are constructed with improved photoelectric switches, and each detection end is connected to the emitter/receiver and the reflector plate arranged across the width direction l of the pool. It is also possible to use a light wave detection type.

Furthermore, the water flow is caused in the pool 1 after the detection end 41 on the side of the water inlet A detects a swimmer, but a predetermined amount of water flow is always allowed to flow in advance, and then the water flow is detected when the swimmer is swimming. You can also adjust it depending on your speed.

Effects of the Invention The embodiment of the water flow rate regulating pool according to the present invention is as described above, and can bring about the following effects.

It is a relatively small pool compared to conventional pools and does not take up much space, and can be used for competitive swimming practice and rehabilitation depending on the athletic ability of the swimmer.It also reduces maintenance costs when used as a heated pool. There are also few.
