A stream water floating apparatus 1 according to the present invention includes a connection body 10 having a predetermined height difference and provided with a third hollow portion 11 on the inside thereof, A lower vortex forming member 12 connected to a lower end of the connecting body 10 and having a first hollow portion 14 communicating with the third hollow portion 11 and connected to an upper end of the connecting body 10, And an upper vortex forming member 15 having a relatively larger diameter than the cross section of the vortex forming member 12 and having a second hollow portion 17 communicating with the third hollow portion 11.

The stream water floating device 1 according to the present invention can be formed to be inclined upward from the lower vortex forming member 12 toward the upper vortex forming member 15. [ That is, the stream water floating device 1 according to the present invention can be formed in a conical shape or the like, in which the sectional area of the upper vortex forming member 15 is large and the sectional area of the lower vortex forming member 12 is small.

The connecting body 10 is disposed between the lower vortex forming member 12 and the upper vortex forming member 15 as shown in Figs. 2 and 3, and the lower vortex forming member 12 and the upper vortex forming member 12, (15) can be arranged while forming a height difference in the vertical direction. The structure of the connecting body 10 may be omitted in terms of the function of forming a vortex. In the present embodiment, the structure of the connecting body 10 will be described.

The connecting body 10 is provided in a different cylindrical shape, and the third hollow portion 11 is provided inside. An upper vortex forming member 15 is disposed on the upper surface of the connection body 10 and a lower vortex forming member 12 is provided on the lower surface. It is preferable that the connecting body 10 is manufactured by winding a shell type thinner in thickness so as to facilitate fabrication.

The connecting body 10 supports the upper vortex forming member 15 and the lower vortex forming member 12 while supporting the difference in height between the upper vortex forming member 15 and the lower vortex forming member 12 . That is, the connection body 10 is provided to have a preset height and maintains a pressure difference to be generated between the lower vortex forming member 12 and the upper vortex forming member 15 at a predetermined level or more.

On the other hand, the sectional shape of the connecting body 10 is not limited to the elliptical shape. If the convenience of manufacture is maintained and the height of the connection body 10 is formed over a certain length, the connecting body 10 having a circular or rectangular cross-sectional shape may be possible.

It is necessary to create a floating stream of river water to clean up sediment contamination in a ditch or a slow river stream, especially in the front of a dam or beam. To this end, in the present invention, an upper vortex forming member 15 and a lower vortex forming member 12 are provided.

2 and 3, the lower vortex forming member 12 is connected to the lower end of the connecting body 10 and has a first hollow portion 14 communicating with the third hollow portion 11 . The lower inflow slit 13 may be formed in the peripheral portion of the lower vortex forming member 12 to inflow the stream water toward the first hollow portion 14. [ In the present embodiment, the lower inflow slit 13 has a V-shaped cross-sectional shape and is formed so that the width of the opening of the slit becomes wider toward the end side.

The upper vortex forming member 15 is connected to the upper end of the connecting body 10 and relatively larger than the cross section of the lower vortex forming member 12 and communicates with the third hollow portion 11 And a second hollow portion 17. Here, the volume of the second hollow portion 17 may be relatively larger than that of the third hollow portion 11 and the first hollow portion 14. This will be described in detail in the description of the operation process by inducing a pressure difference between the lower vortex forming member 12 and the upper vortex forming member 15. [

Like the lower vortex forming member 12, a slit may also be formed in a peripheral region of the upper vortex forming member 15. [ In the present embodiment, the upper vortex forming member 15 is provided with an upper flow-out slit 16, and the upper flow-out slit 16 discharges the river water floated upward through the second hollow portion 17 to the outside .

The lower inflow slit 13 and the upper inflow slit 16 are arranged in parallel to the flow direction of the river water and the openings of the lower inflow slit 13 and the upper inflow slit 16 are formed in the river water As shown in FIG. The stream water is drawn into the first hollow portion 14 through the lower inflow slit 13 of the lower vortex forming member 12 and flows through the third hollow portion 11 and the second hollow portion 17, It is possible to perform the function of floating in the order of the outflow slit 16. The principle of forming the floating stream of the upward flow of water as described above is due to the difference of the amount of swirling generated in the vicinity of the lower inflow slit 13 and the upper inflow slit 16 and the resulting pressure difference, The process will be described in detail.

In the embodiment of the present invention, the sectional shape of the lower inflow slit 13 and the upper outflow slit 16 is V-shaped. Alternatively, the cross section of the third hollow portion 11, Circular, semicircular, or the like, which may serve as a means for communicating the outside with the second hollow portion 14 and the second hollow portion 17, respectively.

The upper vortex forming member 15, the lower vortex forming member 12, and the connecting body 10 having such a structure are preferably integrally manufactured. The upper vortex forming member 15, the lower vortex forming member 12, and the connecting body 10 may each be made of a shell type plate surface structure. Meanwhile, in order to facilitate fabrication, the upper vortex forming member 15, the lower vortex forming member 12, and the connecting body 10 may be manufactured by forming a quadrangular or fan-shaped plate surface structure into an oval shape. In this case, when the plate surface structure such as a quadrangle is formed in an elliptical shape so that one end and the other end in the vertical direction are spaced apart from each other by a certain distance, the above-described lower inflow slit 13 or upper inflow slit 16 need not be manufactured separately Can be.

4 is a schematic view of a vortex formed in the lower vortex forming member 12 and the upper vortex forming member 15 of the stream water suspension device through the vortex formation of the present invention, The lower vortex forming member, the connecting body, and the upper vortex forming member of the stream water suspending apparatus according to an embodiment of the present invention.

Hereinafter, a process of improving the quality of water by operating the river water suspension device 1 through vortex formation according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5. FIG.

The upper vortex forming member 15, the lower vortex forming member 12 and the connecting body 10 generate a flow flow upward to move the substances accumulated on the floor to the upper layer and naturally move to the downstream, It serves to remove pollutants and sediments accumulated on the floor. In this process, it operates according to the law of conservation of energy (Bernoulli's law) of fluid mechanics.

The upper vortex forming member 15 has a larger size (that is, a cross-sectional area in the flow direction of the river water), and the connecting body 10 and the lower vortex forming member 12 may have a relatively smaller size. When both the upper vortex forming member 15, the connecting body 10 and the lower vortex forming member 12 are formed to have an elliptical cross section, it is preferable that the longer major diameter is formed in a larger elliptical shape than the minor diameter. The V-shaped lower inflow slit 13 and the upper inflow slit 16 are formed in the upper vortex forming member 15 and the lower vortex forming member 12, respectively. The lower inflow slit 13 and the upper inflow slit 16 are arranged so as to be parallel to the direction in which the river water flows, with the openings of the slits facing in opposite directions.

4, when the river water flows along the peripheries of the upper vortex forming member 15 and the lower vortex forming member 12, the lower inflow slit 13 and the upper outflow slit 16 A plurality of vortexes can be generated in the adjacent region. At this time, since the size of the upper vortex forming member 15 is relatively larger than that of the lower vortex forming member 12, the amount of the vortex generated near the upper vortex forming member 15 becomes relatively large.

Vortices generally have the effect of reducing pressure. For example, when water in a sink sinks out, the height of the water surface has the same effect as when the vortex is most strongly changed. The pressure drop is relatively small in the vicinity of the lower inflow slit 13 of the lower vortex forming member 12 as compared with the upper inflow slit 16 of the upper vortex forming member 15 in the present invention. A large amount of vortex is generated near the upper flow-out slit 16 of the upper vortex forming member 15 and the pressure drops considerably. On the other hand, in the vicinity of the lower inlet slit 13 of the lower vortex forming member 12, Resulting in a slight drop in pressure. Therefore, the pressure P2 of the upper outlet slit becomes lower than the pressure P1 near the lower inlet slit 13 (P1 > P2).

At the same time or in succession, since the slit section for the lower inlet and the first hollow section 14 of the lower vortex forming member 12 communicate with each other through the lower inlet slit 13, the inside of the first hollow section 14 The pressure P3 can also be substantially approximated to P1. Similarly, the pressure P4 of the second hollow portion 17 can also be substantially approximated to the pressure P2 near the upper flow-out slit 16.

When the pressure drop in the upper and lower portions of the continuous fluid is different from each other, a flow naturally flows toward the portion where the pressure is relatively lowered (the second hollow portion 17). As a result, a pressure gradient in the direction from the third hollow portion 11 to the second hollow portion 17 is formed (pressure gradient from P3 to P4), as shown in Fig.

This pressure gradient serves to flood the river water at the bottom of the stream. The lower inflow slit 13 of the lower vortex forming member 12 serves to attract the surrounding contaminants to the third hollow portion 11 while using the vortex formed around the lower inflow slit 13 can do. The upper inflow slit 16 formed in the upper vortex forming member 15 serves to discharge floating contaminants and river water to the outside.

As described above, by utilizing the constitution of the upper vortex forming member 15 and the lower vortex forming member 12 having different cross-sectional area sizes, the generation amount difference and the pressure difference of the vortex are derived, The water quality can be improved by floating the stream water from the vortex forming member 12 toward the upper vortex forming member 15, while the construction is simple and easy to manufacture, and the manufacturing and maintenance cost can be minimized.

When the floating stream of the river water occurs, the contamination of the bottom of the river can be easily removed because the river water discharged from the upper vortex forming member 15 is floated together with the contamination source of the river bottom.

 In addition, the structure of the apparatus is simple and easy to manufacture, which is advantageous in that maintenance and repair costs are reduced and mass production is possible. In addition, if the lower end of the lower vortex forming member 12 is installed on the bottom of the stream, the installation is completed, which is convenient in terms of device construction.

In addition, the device can be manufactured using a decomposable material such as compressed paper, so that the device can be decomposed spontaneously with time and can be environmentally friendly.

The stream water floating apparatus 1 through the vortex formation may be installed at a predetermined interval in a place where river water purification is required. Needless to say, the purification performance can be further improved through a plurality of floating devices.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
