Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 TECHNICAL FIELD The present invention relates to a water flow generator used in a stagnant water area such as a reservoir, a lake, a marsh, a river, or the sea.

[0002]

[Prior art]

 Conventionally, in a water area in which water has stagnated in a reservoir, a lake, a marsh, a river, the sea, or the like, a water flow generating means having a propeller or the like is floated in the water area by a float, and the water flow generating means creates a flow in the water. Water flow generators that compensate for the lack of dissolved oxygen and prevent eutrophication are known.

In such a water flow generation device, at least a part of the float is in a state of floating on the water surface, so that the surrounding landscape such as a reservoir is often damaged. Therefore, conventionally, artificial rock and food were arranged on the float.

[0004]

[Problems to be solved by the invention]

 However, even if pseudo rocks and the like are placed on the float in this way, it is unnatural if the pseudo rocks and the like are floating in the reservoir and the like, and often do not match the landscape.

In addition, since the float is floated on the water surface, there is also a restriction that a heavy object cannot be placed on the float.

[0006] The present invention has been made in view of the above problems, and has a water flow generation that can generate a water flow in a reservoir or the like and prevent a shortage of dissolved oxygen and eutrophication without damaging the landscape. It is intended to provide a device.

[0007]

[Means for Solving the Problems]

 The water flow generating device according to the present invention includes a float floating on the water surface, a water flow generating means supported in the water by the float to generate a water flow in the water, and a fine mist droplet in the vicinity of the float. A spray nozzle for spraying water and a pump for supplying water from the water to the spray nozzle are provided.

[0008] According to this water flow generation device, the flow of water generated by the water flow generation means supported in the water by the float compensates for the shortage of dissolved oxygen in the reservoir and the like, thereby preventing eutrophication and preventing float. In the vicinity of the mist, fine water droplets in the form of mist are sprayed from the spray nozzle by the water supplied from the pump, so that the float floating on the water surface is hidden by the fine water droplets of the mist and the float can be seen directly. It can eliminate artificial unnaturalness caused by, and prevent the landscape from being damaged.

Further, the spray fountain can generate a large amount of negative ions near the water flow generator.

[0010] Furthermore, the water is agitated by the pump and the spray nozzle, and at the same time, is jetted under pressure, whereby an aeration effect for suppressing the growth of phytoplankton can be obtained.

In such a water flow generating device, it is desirable that the pump be supported underwater by the float. In this way, the weight of the mechanism for generating the spray fountain can be reduced by the buoyancy acting on the pump, and the weight of the pump, which occupies most of the mechanism, is located below the water flow generator so that the water flow is reduced. The generator can be stabilized.

Further, it is desirable that such a water flow generating device includes a plurality of spray nozzles. In this way, the float floating on the water surface can be reliably hidden by spraying.

Further, it is desirable that the spray nozzle is disposed on the outer peripheral side of the float. This makes it possible to generate a spray in the vicinity of the outer peripheral side of the float, which is particularly easily seen from the surroundings, and to more reliably hide the float floating on the water surface.

Further, it is desirable that the spray nozzle is disposed so as to spray fine water droplets in a mist state substantially upward. In this way, the mist of fine water droplets sprayed substantially upward drops by gravity, so that the periphery of the float floating on the water surface can be efficiently hidden by the spray.

Further, it is desirable that the spray nozzle is disposed above the float. By doing so, the mist of fine water droplets sprayed on the upper part of the float falls by gravity, so that the periphery of the float floating on the water surface can be efficiently hidden by the spray.

[0016] Further, in such a water flow generating device, it is desirable to include mooring means for mooring the water flow generating means at a predetermined position in the water area. In this way, the water flow generator can be stably positioned at a predetermined position in the water area where the water flow should be generated for improving the water quality.
