Abstract

PURPOSE:To present a pool of high entertainment and rich in variety by rotating a propeller, provided in a cylindrical cover vertically fixed to the bottom part of the pool, to artificially generate a vortex in water in the pool. CONSTITUTION:A cylindrical cover 2, in which its height is formed lower than a level of water in a pool 1 to form opening parts 2A, 2A for circulating water in the pool 1 in the lower part, is vertically fixed to the bottom part of the pool 1. Next, a normally and reversely rotatable propeller 3 is arranged in the cover 2 and rotated by a motor 5 to artificially generate a suction vortex 7A and a blowout vortex 7B in water in the pool 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an artificial vortex generator, particularly for water in a pool.
The present invention relates to an artificial vortex generator that can locally generate an artificial vortex.

[Conventional technology]

In recent years, pools with various recreational elements have become popular in place of regular pools. For example, pools that can generate artificial waves and endless pools that can generate artificial currents have actually been constructed and are gaining popularity.

[Problem to be solved by the invention]

However, compared to regular pools, pools that can artificially generate waves and currents have more variety, so although they are interesting, they are getting into a rut and require more variety. The development of a rich pool is desired.

Therefore, if it is possible to artificially create a vortex in the water in a pool, the entertainment value of the pool can be further enhanced. No device has yet been proposed.

Therefore, an object of the present invention is to provide an artificial vortex generating device that can easily generate an artificial vortex locally in water in a pool.

[Means to solve the problem]

This invention consists of a cylindrical cover fixed vertically to the bottom of the pool, and a propeller provided within the cover that can rotate in forward and reverse directions, and the height of the cover is lower than the water level in the pool. , the lower part of the cover is formed with an opening through which water in the pool flows, and by rotating the propeller, an artificial vortex is generated in the water in the pool. It is.

Next, embodiments of the artificial vortex generator of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing one embodiment of the artificial vortex generator of the present invention.

As shown in FIG. 1, the artificial vortex generator of the present invention includes a cylindrical cover 2 formed at the bottom of a pool 1 and fixed perpendicularly to the bottom wall of a bit IA, and a cylindrical cover 2 provided inside the cover 2. It also includes a propeller 3 that can rotate forward and reverse.

The upper part of the bit IA is covered with a grid-like lid 4 to prevent danger.

The cover 2 has a plurality of openings 2A formed in its lower part through which water in the pool freely flows. The height of cover 2 is lower than the depth of bit IA.

The propeller 3 rotates forward and reverse as described above by the motor 5 and reducer 6 installed below the bit IA.

According to the artificial vortex generating device of the present invention configured as described above, a vortex is artificially generated in the water in the pool in the following manner.

When the propeller 3 is rotated in one direction by the motor 5 and the speed reducer 6, water in the pool is sucked into the cover 2 from the upper end of the cover 2, and is then discharged from the opening 2A of the cover 2. As a result, a suction vortex 7A rotating in the same direction as the rotation direction of the propeller 2 is artificially generated in the water in the pool as shown by the dotted line in the figure. In this case, since the propeller 3 is surrounded by the cover 2, the suction vortex 7A generated by the rotation of the propeller 3 does not spread around, and the suction vortex 7A is generated locally.

On the other hand, when the propeller 3 is rotated in the opposite direction to the above case, water in the pool is sucked into the cover 2 through the opening 2A of the cover 2, and is then discharged from the upper end of the cover 2.

As a result, a blowout vortex 7B that rotates in the same direction as the rotational direction of the propeller 2 is locally generated in the water in the pool, as shown by the dashed line in the figure.

In this way, it is possible to locally generate eddies in the water in the pool, allowing the user to enjoy a more varied swimming experience.

In addition to the above-mentioned pool, the artificial vortex generating device of this invention has
Of course, it may be installed in other entertainment facilities.

〔Effect of the invention〕

As explained above, according to this invention, it is possible to easily and locally generate an artificial vortex, so by installing it in a pool, it is possible to construct a pool with more variety and higher entertainment value. Useful effects are produced.
