[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically based on embodiments of the invention shown in the drawings. Here, FIG. 1 is a side sectional view of the floating type running water generator.

In the figure, a floating type water generator 1 floats on a water surface, and a propeller 4 in the water rotates to generate a water flow in a vertical direction to generate a circulating flow in a vertical direction around the propeller 4 so as to come into contact with air. This is a device for purifying water by circulating surface water containing oxygen through the water and supplying oxygen into the water.

The floating type water generator 1 mainly comprises a funnel-shaped floating body 2, a shaft 3 mounted on the floating body 2, a propeller 4 mounted on a lower end of the shaft 3, a duct 7 provided around the floating body 2, and the like. Is configured.

The floating body 2 floats on the water surface. For example, the floating body 2 has a hollow inside or is filled with a material having a specific gravity smaller than that of water. It has a funnel-shaped inverted conical curved surface shape that spreads around.

For this reason, the water around the floating-type running water generator 1 rises or falls along the funnel-shaped side peripheral surface. In other words, the water in the water spreads around as it ascends, or the water on the surface of the surrounding water that descends has a downward flow in the center as it descends.

A shaft 3 is attached to the floating body 2 in a vertical direction. The shaft 3 extends vertically through the center portion of the funnel-shaped floating body 2. The shaft 3 is attached so as to penetrate the water surface, and the lower end of the shaft 3 is extended to the lower end of the funnel-shaped floating body 2 which is the most narrowed and narrowed. 4 are attached.

The propeller 4 has a function of rotating horizontally about the shaft 3 to generate flowing water in the vertical direction. The propeller 4 is freely rotatable in forward and reverse directions. For example, when the propeller 4 rotates forward and backward, the propeller 4 generates upward running water, and when the propeller 4 rotates in the reverse direction, downward running water can be generated.

The upper end of the shaft 3 penetrating the center of the floating body 2 in the vertical direction is connected to a driving device 5 installed at the center of a planar upper end located above the water surface of the floating body 2. That is, the upper end of the shaft 3 is connected to a motor (not shown) of the driving device 5 via a speed reducer, and the driving force from the driving device 5 rotates the shaft 3 so that the propeller 4 at the lower end of the shaft 3 is driven. Rotate to create up and down running water.

The driving device 5 is housed in, for example, a box-shaped machine frame. The drive device 5 is prevented from being damaged by water, seawater, or the like. In addition, a solar cell 6 is installed as an electric power source for supplying electric power to the driving device 5 on an upper portion of the box-shaped machine frame accommodating the driving device 5. When the solar cell 6 is not used, a cable for supplying electric power from land is connected to the floating-type running water generator 1.

When the solar cell 6 is installed, there is no need to connect a cable for supplying electric power from the land to the floating water generator 1, and there is no obstructive cable. Can be freely floated on the surface of the water at any position away from the land.

A duct 7 is attached around the outside of the funnel-shaped floating body 2 and the propeller 4 so as to open a fixed gap and open the upper part in a trumpet shape. An up-and-down flow channel 8 is formed in an annular shape between the inner peripheral side surface of the duct 7 whose upper part expands like a trumpet and the outer peripheral side surface of the funnel-shaped floating body 2 located inside the duct 7.

The upper end of the duct 7 has a trumpet shape, and the lower end of the duct 7 extends below the position of the propeller 4 attached to the lower end of the funnel-shaped floating body 2. The upper water can be sent and circulated, and the water in deep water can be raised and circulated to the surface of the water.

In particular, the duct 7 whose upper part expands like a trumpet
If the lower end of the duct 7 extends further downward than the position of the propeller 4, the suction and discharge locations formed at the upper and lower ends of the duct 7 can be separated and separated, and interference between the suction and the discharge can be prevented. Can be suppressed.

The duct 7 is connected to the floating body 2 by a plurality of connecting members 9 so that the upper end of the duct 7 having a flared shape is located slightly below the water surface. ing. The plurality of connecting members 9 are connected to the up-down flow channel 8.
Are mounted radially at regular intervals in the middle of the. As the plurality of connecting members 9, members having a shape that does not cause resistance of flowing water that moves up and down the up-and-down flowing water channel 8 are used.

Since the upper end of the duct 7 which spreads in a trumpet shape is located slightly below the water surface, when the propeller 4 is rotated to generate downward flowing water,
Only the water containing oxygen by touching the air near the water surface can be efficiently sucked into the up / down flow channel 8 inside the duct 7 and sent into deep water.

A mounting hole 1 for connecting a mooring rope 10 is provided on the outer peripheral side surface of the duct 7 whose upper part is expanded in a trumpet shape.
1 is attached. The mooring rope 10 has one end connected to the mounting hole 11 and the other end connected to a water bottom (not shown) by an anchor or the like.

When the propeller 4 is rotated by utilizing the thrust component of the propeller 4 by providing the inclination of the shaft 3 three-dimensionally by the mooring rope 10, Can circularly move on the water surface around an anchor (not shown) on the water bottom to which the other end of the water bottom is connected.

Next, the operation based on the configuration of the embodiment of the present invention will be described below. For example, the floating water generator 1 is carried to a closed water area in which water is dirty, such as lake water, in a bay, an estuary area, a dam, a reservoir, a pond, and a farm, and floats on the water surface.

The duct 7 of the floating type running water generator 1
One end of the mooring rope 10 is connected to the mounting hole 11 on the outer peripheral side of the mooring rope, the other end of the mooring rope 10 is connected to an anchor (not shown), and the anchor to which the other end of the mooring rope 10 is connected is fixed to the bottom of the water. . After that, the floating type running water generator 1 is driven.

When the solar cell 6 is attached to the floating water generator 1, the electric power obtained by the solar cell 6 is supplied to the driving device 5. When the solar cell 6 is not attached to the floating type running water generator 1, a power cable is connected to the driving device 5 from the land to supply power.

In the driving device 5 which has been supplied with electric power, the motor of the driving device 5 is driven, and the driving force of the motor causes the shaft 3 to rotate around one direction via the reduction gear. When the shaft 3 rotates, the propeller 4 attached to the lower end of the shaft 3 rotates in one direction.

When the rotation of the propeller 4 in one direction rotates the water on the surface of the water into the water, that is, the rotation of the propeller 4 so as to generate downward flowing water, the water on the surface of the water containing oxygen upon contact with the air becomes: Over the upper end of the duct 7 whose upper end is located near the water surface, it flows into an annular up-down flow channel 8 formed between the inner peripheral side surface of the duct 7 and the outer peripheral side surface of the funnel-shaped floating body 2.

The water on the water surface containing oxygen that has flowed into the up-and-down flow channel 8 descends in the up-and-down flow channel 8 by the downward flowing water generated by the rotational force of the propeller 4, and extends downward. It is sent out from the lower end of the duct 7 into deep water.
Since the water on the surface of the water discharged into the deep water contains a large amount of oxygen, it is possible to supply a large amount of oxygen into the water with a lack of oxygen. It becomes possible to purify dirt.

As described above, when the rotation of the propeller 4 is continued, the downward flowing circulation of the water on the water surface containing oxygen into the water occurs, and the water on the water surface containing oxygen continues to be supplied into deep water. Then, the water around the outside of the duct 7 gradually rises, and downward flowing water is generated inside the duct 7 and upward flowing water is generated outside the duct 7.

In this manner, ascending and descending circulating water is generated inside and outside the duct 7, and circulating water for supplying water on the oxygen-containing water surface to deep water is generated around the floating type water generating device 1, and the closed water area Purification of the water in is efficiently achieved.

On the other hand, when the direction of rotation of the propeller 4 in one direction rotates in the opposite direction to the above, and the direction in which the water in the water is sent out onto the surface of the water, that is, when the propeller 4 rotates so as to generate ascending water, The dirty water in the water, which contains almost no oxygen, flows from the lower end of the underwater duct 7 into an annular up-down flow channel 8 formed between the inner peripheral surface of the duct 7 and the outer peripheral surface of the funnel-shaped floating body 2. Flows into the lower part of.

The dirty water in the water containing almost no oxygen and flowing into the lower part of the up-and-down flow channel 8 rises in the up-and-down flow channel 8 by the ascending flow water generated by the rotational force of the propeller 4, and the upper wrapper It is sent out onto the water surface from the upper end of the duct 7 that spreads out. The dirty water sent out onto the surface of the water comes into contact with air where oxygen is absorbed. In this way, dirty water containing little oxygen is sent to the surface of the water and purified by absorbing oxygen.

As described above, when the rotation of the propeller 4 is continued, a circulation of ascending flowing water is generated which sends dirty water containing almost no oxygen to the surface of the water, and the water in the dirty water containing almost no oxygen is generated. As the water continues to be sent out onto the water surface, the water around the outside of the duct 7 gradually descends, so that rising flowing water is generated inside the duct 7 and descending flowing water is generated outside the duct 7.

In this way, ascending and descending circulating water is generated inside and outside the duct 7, and circulating flowing water for supplying water on the oxygen-containing water surface to deep water is generated around the floating-type flowing water generator 1, and the closed water area is formed. Purification of the water in is efficiently achieved.

In this manner, ascending and descending circulating water is generated inside and outside the duct 7, and circulating water that sends dirty underwater containing almost no oxygen to the surface of the water is generated around the floating-type running water generator 1 and closed. Purification of water in the watery area is efficiently achieved.

By the way, since the floating type water generator 1 is connected to the anchor at the water bottom through the mooring rope 10, the floating type water generator 1 is driven by the reaction when the propeller 4 rotates to generate circulating water. Therefore, the periphery of the anchor can be efficiently purified because the periphery of the anchor rotates around the anchor.

It should be noted that the present invention is not limited to the above embodiment of the present invention, and it is needless to say that various modifications can be made without departing from the spirit of the present invention.

As is apparent from the above description, according to the floating water generator according to the present invention, a funnel-shaped floating body floating on the water surface and having an upper side expanding is provided, and the floating body penetrates the water surface. The shaft extends downward, a propeller that rotates around the axis is attached to the lower end of the shaft connected to the driving device, and a duct whose upper part expands like a trumpet is provided around the funnel-shaped floating body, and the lower end of the duct is provided. The side extends to below the propeller, forms an annular up-down flow channel between the outer peripheral side surface of the funnel-shaped floating body and the inner peripheral side surface of the duct, and causes the up-down flow water in the up-down flow channel by the rotating propeller, By generating up-and-down circulating water in the water inside and outside the duct, water containing oxygen on the water surface can be sent into the water through the up-and-down flow channel, or dirt containing almost no oxygen through the up-and-down flow channel Water Of water can be absorbed oxygen in the air feed on the water surface, which makes it possible to achieve the purification of water in closed water areas efficiently.

Further, when the mooring rope is connected to and supported on the water bottom by the mooring rope, the other end of the mooring rope pivots around the connected and supported water bottom. In addition, it is possible to efficiently purify the periphery of the connection portion at the bottom of the water.

In the case where a solar cell for supplying power to the shaft driving device is provided on a floating body, a cable for supplying power from the land may be connected to the floating type running water generator. Since there is no need for connection to the water and no obstructive cables, the floating water generator can be freely floated and operated on the water surface at an arbitrary position away from land. Also, it is possible to prevent the cable from being caught on a part of the device and hindering the operation.
