FIG. 1 is a perspective view showing the overall appearance of a water circulation apparatus according to the present invention, and FIG. 2 is a sectional perspective view of a water circulation apparatus according to the present invention.

1 and 2, the water circulation apparatus according to the present invention will be described with reference to FIGS. 1 and 2, wherein the water circulation apparatus includes a body 100, which is floated in water, And a rotating body 200 that generates a wave in the upper surface of the lake by being rotatably connected to the upper portion of the rotating body 200. Characteristically, the lower portion of the rotating body 200, that is, A buoyancy regulating part 140 is provided to allow the buoyancy regulating part 140 to be placed in a flooded state at the lower part so as to cause the buoyancy to be more efficiently generated when the buoyancy regulating part 140 is locked under the water surface.

The body 100 is a cylindrical housing, and the interior of the body 100 is divided into a plurality of spaces. Each space is a physical space in which various structures necessary for the operation of the water circulation apparatus of the present invention can be implemented And is used as a passage.

More specifically, the body 100 is formed in a cylindrical shape and is divided into three horizontally divided upper, lower, upper and lower rooms 100a, 100b and 100c, The upper room 100a is formed to be smaller in diameter than the middle room 100b and the lower room 100c to form a step with the upper surface of the middle room 100b. As shown in the drawing, a central room 100d, which is a vertically long cylindrical housing having a smaller diameter than the body 100 formed to pass through the center of the three layers, Respectively. Each of the spaces provided as described above includes various configurations of the present invention to implement various functions.

That is, the body 100 uses the partitioned rooms to separate the buoyancy providing part 110, the water treatment agent mixing part 120, the head positioning part 130, the buoyancy adjusting part 140, and the fixed support part 150 The buoyancy providing part 110 is formed on the outer surface of the middle floor room 100b and the water treatment agent mixing part 120 is used on the inner space of the middle floor room 100b, The buoyancy control part 140 is formed by using the inner space of the lower room 100c and the fixed support part is formed in the lower room 100c through the central room 100d and the upper room 100a. And extends from the outer surface.

The rotating body 200 has a shape corresponding to the shape of the upper floor room 100a so as to cover the upper floor room 100a so as to be rotatably connected to the upper floor room 100a, A blade 221 capable of generating water can be formed so that the rotating body 200 rotates on the basis of the body 100 to generate water on the water surface area.

The buoyancy providing part 110 extends outward along the upper side of the upper side of the middle floor room 100b and supports the weight of the body 100 and buoyancy so as to float on the water surface. . The buoyancy providing part 110 may extend from a part of the side upper part of the middle-floor room 100b or extend outward from the entire circumference of the middle-floor room 100b according to the size and the weight of the body 100, And may be formed of various materials other than the buoyant body such as foamed synthetic resin such as foamed polyethylene or foamed urethane in a line which does not hinder the main function of providing buoyancy. As the buoyancy providing part 110 is provided, the body 100 of the present invention is positioned from the water surface with respect to the buoyancy providing part 110, and the upper part of the buoyancy providing part 110 And the lower part of the buoyancy providing part 110 is flooded to the lower side of the water surface. Since the buoyancy providing part 110 is formed on the upper part of the middle floor room 100b, the upper floor room 100a is disposed on the water surface.

When the upper room 100a is disposed on the water surface, the blade 221 of the rotating body 200 is also exposed to the outside of the water surface, so that the amount of water that the blade 221 can flow during rotation is significantly reduced, It becomes difficult to give. In order to solve this problem, the water circulation apparatus of the present invention includes a buoyancy regulating part 140 for regulating the buoyancy applied to the water surface by the buoyancy providing part 110, The depth of sinking of the body 100 from the water surface can be adjusted according to the amount of water accommodated in the inner space of the lower room 100c. That is, the buoyancy control part 140 is configured to easily and easily adjust the buoyancy by injecting water into the interior of the lower-layer room 100c, that is, the water-receiving space. To this end, The accommodation space forms the water inlet / outlet 141 and the air inlet / outlet 142.

The air inlet / Hole extending through the air inlet / outlet hole formed at a portion spaced a predetermined distance from the water inlet / outlet aperture. When water is injected into the lower-layer room 100c, water is received from the lower part of the lower-layer room 100c, so that the lower part of the lower-layer room 100c, The upper portion of the lower-layer room 100c, that is, the portion where the air is received, communicates with the air inlet / outlet 142 and communicates with the upper portion of the water surface.

The body 100 of the present invention is placed in the lake and the manager located at the upper part of the water surface floats on the water surface by the buoyancy providing part 110 and water is first introduced into the lower room 100c through the water inlet / When the air is injected, air of the volume of the water remaining in the water receiving space is automatically discharged through the air inlet / outlet 142 and water is injected. At this time, the buoyancy applied to the body 100 is adjusted according to the amount of water injected. When the lower side of the upper room 100a is submerged in water, that is, when the blade 221 is totally immersed in water, By stopping the injection, the degree of immersion of the body 100 in the water can be controlled. When the buoyancy changes due to various environments around the time, the body 100 is taken out to the outside or the water inlet / outlet 141 or the air inlet / 100c can be easily controlled.

The water inlet / outlet 141 and the air inlet / outlet 142 may be formed so as to pass through one side of the buoyancy providing part 110 to be more firmly fixed.

The water treatment agent mixing part 120 is a passage through which water in the lower part of the lake, that is, deep-seated water outside the body 100, flows into the body 100 and passes through the headlamp injection part 130, And corresponds to the inner space of the middle-layer room 100b in which deep-seated water outside the circulation unit is mixed with the water treatment agent 120a and flows. In order to allow the inner space of the middle-layer room 100b to be utilized as a deep-water inflow passage for storing the water treatment agent 120a, the middle-layer room 100b is provided with an inner- A plurality of first inlet holes 121 are formed through the first inlet holes 121 and the second inlet holes 121. A surface of the outer circumferential surface of the center room 100d that forms a boundary with the middle room 100b has a diameter smaller than that of the first inlet holes 121 A plurality of second inflow holes 122 are formed. In the inner space of the middle-floor room 100b, a lumpy water treatment agent 120a is stored. Due to the difference in diameter between the first inlet hole 121 and the second inlet hole 122, the flow rate of the deep- So that the elution of the water treatment agent 120a can be facilitated.

Particularly, since the first inflow hole is formed along the sidewall of the middle-layer room 100b, that is, the central portion of the side wall of the body 100, the water circulation apparatus of the present invention does not inflow the low- It is possible to prevent the side effect that causes the elution of the nutrients that have settled in the jarney.

In this case, the water treatment agent 120a is preferably a metal salt that dissolves in water and releases cations so that the water treatment agent 120a flocculates and flocculates underwater nutrients floating in the water in an anion state. In particular, Are most suitable for application to the water circulation apparatus of the present invention. The reason for this is that the above water-soluble silicate is a colorless, tasteless, odorless, non-toxic environment-friendly, pollution-free water treatment agent concentrating water-soluble silicic acid such as Na2SiO3 and the like, Not only is it superior to the basic functions that effectively prevent it, but it can also relieve the algae phenomenon more efficiently by suppressing bacterial habit and increasing dissolved oxygen. The water-soluble silicate was eluted from the surface according to the flow of the deep water from the first inflow hole 121, and dissolved in the deep water. The weight of the water-soluble silicate decreased by about 25% per 6 months. That is, it is preferable that the water-soluble silicate is further added with 1/4 weight of the initial injection amount every 6 months, and one side of the middle-layer room 100b, preferably the top side, (123) should be formed.

The head-on spraying part 130 injects the deep seawater received in the central room 100d and the upper room 100a through the water treatment agent mixing part 120 to the upper part of the body 100, A pump 131 and a nozzle 132.

The head pump 131 is provided inside the central room 100d to provide a power for lifting the mixed deep water of the water treatment agent 120a flowing through the second inlet hole 122 upward, So that it can be injected directly to the upper side. A separate power supply module and a controller are required for driving the lifting pump 131. This is because the lifting pump 131 is a jet pump that injects water into the upper chamber 100a It is preferable to store it on one side.

The nozzle 132 is connected to the nozzle 131 and extends to one side of the upper outer circumferential surface of the body 100, that is, to one side wall of the upper chamber 100a. A plurality of jetting ports 132a are formed in the upper portion of the outer circumferential surface of the upper chamber 100a so as to receive the extension ends of the nozzles 132 through the outer circumferential surface. In other words, the nozzle 132 is formed so as to extend upward from the positive displacement pump 131, and to be split at the upper side and inserted into the injection port 132a.

According to the constitution of the upright pump 131 and the nozzle 132, the head positioning part 130 raises the deep water introduced into the central room 100d to form a jet hole (not shown) formed along the upper periphery of the upper room 100a 132a to the outside of the body 100 with a strong pressure.

The rotating body 200 is provided with a plurality of blades 221 connected to the upper part of the body 100, that is, the upper surface of the upper room 100a via a rotating shaft, and arranged in a direction perpendicular to the water surface, And the blade 221 is formed in a direction perpendicular to the water stream injected by the injection port 132a and flows by the water pressure. More specifically, the rotating body 200 includes a cap part 210 and a blade part 220. The cap part 210 covers the upper room 100a from above, And a circumferential surface extending downward along the circumference of the upper surface. Particularly, the circumferential surface is tapered outward to form a lower area than the upper part of the circumferential surface to guide the space in which the blade part 220 can be formed. The center part of the upper surface of the cap part 210 is rotatably connected to the upper part of the upper room 100a through a shaft 210a and a bearing 210b. That is, the cap part 210 is formed so as to be rotatable with respect to the upper part of the body 100, that is, the upper part room 100a with respect to the axis.

That is, the rotating body 200 is a kind of impeller and does not rotate by a separate motor, but is rotated by the water pressure of the water stream injected by the headlamp injection part 130, ) Is driven to rotate. With this principle, as the rotary body 200 is rotated, a wavelength is generated in the upper part of the lake, and water below the lake is drawn up by the water pressure difference formed thereby. The water circulation apparatus of the present invention has a highly efficient water circulation due to the interaction of the direct water circulation through the above-mentioned head-on injection part 130 and the convection phenomenon generated according to the water pressure difference generated by the rotary body 200 It is possible to do.

Particularly, in order to control the wavelength and the wave height by controlling the rotational driving force of the rotating body 200, the bottom surface of the cap part 210, that is, the surface contacting the upper end of the blade 221, The blade 221 disposed between the support surfaces and perpendicular to the water surface may be adjustable in the left and right angles. To this end, the blade 221 is fixed only on a bottom surface of the cap part 210 and a bearing surface of the blade part 220 and a specific part of the blade 221, .

In addition, a lower opening / closing panel 222 may be additionally provided on one side of the receiving surface so that the wavelength and corrugation generated in the water surface may be formed longer and higher, So as to be formed between the blades 221 and the blades 221 as shown in the figure, and a plurality of the blades 221 may be formed.
