As an apparatus for improving water quality, an underwater motor, and a vane disposed at one end (front side) of the underwater motor and rotating with an output rotation shaft of the motor to stir water and flow forward. 2. Description of the Related Art A water flow generating device including a car is known. According to this water flow generation device, the water in the region with a large amount of dissolved oxygen in the upper layer below the water surface and the amount of dissolved oxygen in the dead water region and the lower layer below the water surface are reduced by stirring and flowing the water in the pond forward by the impeller. By replacing the water in the area, the dissolved oxygen in the pond can be uniformly dispersed and the water quality can be improved. However, this type of conventional water flow generation device only disperses the dissolved oxygen in the pond uniformly by stirring and flowing the water forward. And does not have a function to actively purify water. Therefore, there is a disadvantage that the degree of improvement in water quality is restricted.

When the water discharged from the discharge port of the pump passes through the ejector, the pressure in the suction chamber of the ejector decreases, and air (atmosphere) is sucked from the fountain tube. Therefore,
The air-water mixed fluid containing air bubbles is discharged from the ejector into the water, aeration is performed, the water is positively purified, and the water quality can be improved. On the other hand, when the pump installed in the water is operated with the aeration / fountain switching valve opened, the water discharged from the discharge port of the pump blows out into the atmosphere through the fountain pipe, and the fountain can be performed.

In this figure, a water flow generating device having an aeration function and a fountain function is branched and connected to a submersible pump 1, an ejector 2 attached to a discharge port 1A of the submersible pump 1, and a suction chamber 2A of the ejector 2. A fountain pipe 3 having a tip 3A opened above the water surface WL such as a pond, and an aeration / fountain switching valve 4 formed by a solenoid valve or an electric valve is interposed at a position downstream of the suction chamber 2A of the ejector 2. I have.
The submersible pump 1 is attached to the float 5 and is always installed at a predetermined position in the water. The distal end of the ejector 2 is surrounded by a bell-shaped casing 6 whose both ends in the axial direction are open and whose distal end has a smaller diameter than the rear end.

Is operated, the water discharged from the discharge port 1A of the submersible pump 1 passes through the ejector 2 and is discharged into the water (arrow W1). In this case, as shown by the arrow W2, water is also sucked from the opening on the rear end side of the casing 6, and flows toward the front of the casing 6 as shown by the arrow W3. When the water discharged from the discharge port 1A of the pump 1 passes through the ejector 2, the pressure in the suction chamber 2A of the ejector 2 decreases, and the air (atmosphere) is sucked from the fountain pipe 3 (arrow E). Therefore, the air-water mixed fluid containing air bubbles can be discharged from the ejector 2 into the water of a pond or the like to perform aeration, thereby actively purifying the water and improving the water quality.

The direction of the air-water mixed fluid is fluctuated. Thereby, it is possible to selectively perform aeration in a region where the amount of dissolved oxygen is lower in the upper layer below the water surface WL and aeration in a region where the amount of dissolved oxygen is lower in the lower layer below the water surface, and swing the casing 6 up and down by the operating mechanism. By doing so, it is also possible to continuously repeat the aeration of the region with a high dissolved oxygen content in the upper layer below the water surface WL and the aeration of the region with a small amount of dissolved oxygen in the lower layer below the water surface.
