BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a water purifying apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large-area part type water quality purification apparatus, and more particularly, to a large-area part type water quality purification apparatus that can be rotated at a constant radius without staying in one place, will be.

Generally, since the wastewater from the surface, sewage, factory, agriculture, and wastewater are continuously flowed into the closed waters where the access to the waters is not active, such as lakes, gulfs, estuaries, dams, reservoirs, The concentration of the pollutants in the water is increased.

Nutrients such as nitrogen compounds and phosphates in pollutants cause eutrophication in fresh water because they promote the growth and proliferation of microorganisms causing decomposition of organic matter.

Eutrophication is a phenomenon in which abnormal growth of algae occurs due to the increase of nutrients such as nitrogen and phosphorus in fresh water due to decomposition of organic matter by microorganisms. Such eutrophication damages the turbid ecosystem of the lake, such as lowering the turbidity of fresh water, producing bad smell by decay, and severely damaging fish in the water.

In particular, oxygen is not supplied to the lower layer of the closed water body where the flow of water is almost stagnant, so that the contamination of the water from the bottom becomes severe.

Therefore, it is important to maintain the equilibrium so that the amount of nutrients such as nitrogen or phosphorus contained in the aquatic ecosystem does not exceed the self-purification capacity. In particular, it is important that the organic matter and heavy metals It is very important to ensure that the purification action of the liquid is smoothly performed.

However, many dams, reservoirs and lakes in Korea are still experiencing worsening water quality due to the introduction of a large amount of contaminants and the formation of a dense layer according to long-term fresh water, to be.

In order to prevent such deterioration of water quality, water purification apparatuses are being developed which purify water by artificially generating water flow by floating on the water surface, reducing the temperature deviation per depth layer and improving the contact with air. However, since the conventional water purification apparatus is fixed at the place where the water purification apparatus is installed, there is a problem that the water quality that can purify the water quality is very limited.

Korean Patent Registration No. 10-1122053 discloses a water purification apparatus capable of cleaning a large area while rotating a fan unit around a main body fixed in water.

However, the patented technique does not specifically disclose a solution for supplying electricity to the fan unit which is connected to the apparatus main body and revolves. In addition, since the fan unit is connected to the apparatus main body and is fixed at a predetermined height, when the water level becomes high, when the water is submerged and the water level becomes low, the fan unit becomes floating from the water surface, There is a problem.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a purification module for purifying water quality, which can rotate around a buoyant body fixed in water, And to provide a large-area-portion-type water quality purification device capable of easily supplying electricity to a large-area-type water quality purification device.

The connection means includes a slip ring provided on an outer circumferential surface of the support rod and connected to the power cable, and a brush installed on an inner circumferential surface of the rotary member to be in contact with the slip ring and connected to the connection cable.

The brush includes a casing of a non-conductive material provided on an inner circumferential surface of the rotating member, mercury filled in the casing and in contact with the slip ring, and a brush provided on the rotating member to electrically connect the mercury and the connection cable And a connection terminal to be connected to the terminal.

And a direction restricting means for restricting the rotation direction of the purifying module rotating around the buoyant body in one direction.

And a water level corresponding means for allowing the purifying module to move up and down in accordance with the water level change.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a large area type water quality purification apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The water purification apparatus of the present invention is intended to improve the quality of water by installing the water purification apparatus in a stagnant water body such as a lake, a bay, an estuary area, a dam, a reservoir, a pond, a farm,

1 to 4, a water purification apparatus according to an embodiment of the present invention includes a buoyant body 10, a fixing unit 20, a rotary member 30, a connecting bar 31, A purifying module 40, and connection means.

The buoyant body (10) is installed so that the whole body is immersed in water or partly exposed to the water surface. The buoyant body 10 may be formed of a material having a specific gravity smaller than that of water so as to have buoyancy in water or may be formed in a hollow structure having an empty interior. The buoyant body 10 of the hollow structure has an advantage that the buoyant force of the buoyant body 10 can be adjusted by filling water therein or by emptying the water. In this case, an inlet (not shown) may be formed on the upper surface of the buoyant body 10 so that water can be injected into the buoyant body 10. A plug or valve is provided at the injection port to enable opening and closing of the injection port.

The fixing part 20 for fixing the buoyant body 10 in water comprises a fixing bar 23 having one side connected to the bottom face of the buoyant body 10, an anchor member 21 fixed to the floor, And a connecting rope 27 connecting the fixed bar 23 and the fixed bar 23 to each other.

One side of the fixing bar 23 is coupled to the bottom surface of the buoyant body 10, and the other side extends outwardly of the buoyant body 10. The other end of the fixing bar 23 is provided with a hook 25 so that the connecting rope 27 can be bundled. At least two fixing bars 23 may be provided. In the illustrated example, three fixing bars 23 are installed at intervals of 120 degrees. The fixing bars 23 are disposed between the plurality of connecting ropes 27 to prevent them from being twisted.

The connecting ropes 27 are appropriately adjusted in accordance with the length and the number of the fixing bars 23. For example, when the three fixing bars 23 are installed at intervals of 120 degrees, the length of the fixing bar 23 is preferably 1 m, and the length of the connecting ropes 27 is preferably 1 to 3 m.

A support rod 15 is vertically installed on the upper portion of the buoyant body 10. The lower portion of the support rod 15 is fixed to the buoyant body 10. The upper portion of the support rod 15 provided on the buoyant body 10 protrudes above the water surface. The support rod 15 may have a hollow structure with an empty interior.

The rotary member (30) is rotatably coupled to the support rod (15). The rotary member (30) has a cylindrical structure surrounding the outside of the support rod (15). A bearing 35 is provided between the support rod 15 and the rotary member 30 so that the rotary member 30 rotates about the support rod 15. Preferably, self aligning bearings are applied to the bearings 35. Therefore, even when the rotary member 30 is tilted, the rotary member 30 can be smoothly rotated by the careful action.

The purifying module 40 circulates water while floating on the water surface to purify the water. The purifying module 40 is connected to the rotary member 30 by a connecting bar 31. One side of the connecting bar 31 is coupled to the outer circumferential surface of the rotary member 30 and the other side is coupled to the purifying module 40.

The purifying module 40 includes a float 41 rotating around the buoyant body 10, a blade 50 provided below the float 41, And a motor for rotating the rotor 50.

The float 41 is for floating the purifying module 40 on the water surface and may have a conventional float structure that can float on the water surface.

The blade 50 is installed under the float 41. The blade 50 has a boss portion 51 which is axially coupled to the driving shaft 45 of the motor and a plurality of web unit units extending radially from the boss portion 51.

The web unit includes a rod 54 installed radially from the boss 51 and a web 55 installed on the end side of the rod 54. The web 55 is formed to be inclined with respect to the longitudinal direction of the rod 54, and the inclined direction is formed so that the inner end of the web 55 can be projected toward the rotation direction side. The web 55 supported by the rod 54 may be supported in parallel with the rod 54 or may be formed in a plate extending vertically downward.

The structure of the above-described blade is disclosed in Korean Patent No. 10-1259593, and a detailed description thereof will be omitted.

The motor for rotating the blade 50 installed in the float 41 is embedded in the housing 43 provided on the float 41. The upper surface of the housing 43 is connected to the connecting bar 31.

The purifying module 40 may further include control means (not shown) for controlling the number of revolutions of the blade 50 by controlling the motor. By this control means, the number of revolutions of the blade 50 can be controlled to 0.1 to 20 rpm.

The motor provided in the purifying module 40 is electrically operated. To this end, a cable is connected from the power source installed on the ground to the motor to supply electricity. In this embodiment, the cable is divided into a power cable 5 and a connection cable 75. The power cable 5 extends from the ground mounted power source to the inside of the support rod 15 provided on the buoyant body. The connection cable 75 is installed along the connection bar 31 and connected to the motor of the purification module 40. The connection cable 75 may be installed inside the connection bar 31.

When the power supply cable and the connection cable are directly connected, the connection cable (75) provided on the connection bar (31) is twisted when the purification module rotates around the float (10). In order to prevent this, the present invention is provided with connecting means for electrically connecting the power cable 5 and the connecting cable 75 while preventing the connecting cable 75 from being twisted.

As an example of the connecting means, a slip ring can be applied. A slip ring 60 provided on the surface of the support rod 15 and connected to the power cable 5, a connection cable 75 provided on the inner circumferential surface of the rotary member 30 to contact the slip ring 60, And a brush to be connected thereto.

The slip ring 60 is formed of a conductive material such as iron or copper. Two slip rings 60 are vertically spaced apart. The + and - wires of the power cable 5 are connected to the two slip rings 60, respectively.

The power cable 5 drawn into the float 10 extends to the top of the support rod 15 and is connected to the slip ring 60. The power cable (5) is connected to a grounded power source. Commercial power can be used as a power source.

The brush contacts the slip ring 60 while rotating to allow electricity to flow. A conventional carbon brush can be used as the brush.

Further, as shown in Fig. 3, it is possible to use a brush filled with mercury therein. 3 includes a casing 65 of a non-conductive material provided on the inner circumferential surface of the rotary member 30 and mercury 67 filled in the casing 65 and in contact with the slip ring 60. [ And a connection terminal 70 provided on the rotary member 30 for electrically connecting the mercury 67 and the connection cable 75 to each other.

The casing (65) has a receiving space in which the mercury (67) can be filled. The casing 65 is formed so as to surround the slip ring 60 provided on the support rod 15. [ The casing 65 is formed of a non-conductive material. The end of the casing 65, which is in contact with the outer circumferential surface of the support rod 15, has an open structure. Although not shown, a sealing member is provided at an end of the casing 65 to prevent leakage of mercury to the outside. Two casings (65) are arranged so as to be equal to the number of the slip rings (60) so as to be vertically spaced apart.

The inside space of the casing (65) is filled with mercury (67). Mercury is a conductive metal in liquid form. The mercury 67 filled in the casing 65 can be kept in contact with the slip ring 60 at all times even if the casing 65 rotates.

The connection terminal 70 is provided on the rotary member 30 to electrically connect the connection cable 75 and the mercury 67. The connection terminal 70 is formed of a conductive metal material. Two connection terminals 70 are vertically spaced apart and installed side by side on the rotary member 30. One end of the connection terminal (70) is located inside the casing (65) and contacts the mercury (67). The other end of the connection terminal (70) penetrates through the rotary member (30) and protrudes into the inside of the connection bar (31). A connecting cable 75 is connected to the other end of the protruding connection terminal 70. The connection cable 75 extends in the direction of the purifier module 40 along the inside of the connection bar 31, which is a hollow structure, and is connected to the motor.

As described above, the power can be easily supplied to the cleaning module 40 that rotates using mercury, which is a liquid metal. And, unlike the illustrated embodiment, the cleaning module 40 may be supplied with power by using a conventional rotary joint as a connecting means.

When power is supplied from the power cable 5 to the connection cable 75 by the connecting means, the blade 50 is rotated by the operation of the motor. As the blade 50 rotates, water rises from the lower layer of water, and the raised water spreads radially along the water surface around the blade 50. This movement of water flows along the water surface 40 times or more of the radius of the blade 50, and thus generates a circulation stream circulating between the upper and lower layers. The formation of this circulation stream enhances the contact between water and air to increase the amount of oxygen dissolved in the surface water, and cleans the surface of the water by removing the fluke of plankton that floats on the surface due to the oxygen bubbles generated by photosynthesis. Particularly, the water of the water having a high dissolved oxygen amount moves downward in the course of circulation and serves to supply oxygen to the lower side.

On the other hand, when the blade 50 rotates, a rotation moment is generated in the connecting bar 31. By this rotation moment, the purifying module 40 rotates around the buoyant body 10. The rotational direction of the purifying module 40 rotating around the buoyant body 10 is opposite to the rotational direction of the blade 50. [ As described above, the purifying module 40 is not fixed in one place, but it circulates around the buoyant body 10 to purify the water quality, so that water quality in a relatively wide area can be purified.

The rotational speed of the purifying module rotating around the buoyant body is preferably 0.05 to 5 rpm. When the rotation speed is less than 0.05 ppm or exceeds 5 ppm, the effect of purifying water is deteriorated.

In another embodiment of the present invention, a direction limiting means for limiting the rotation direction of the purifying module 40 rotating around the buoyant body 10 in one direction may be provided.

5, the direction restricting means includes a ratchet gear 80 formed on the inner circumferential surface of the rotary member 30 and a pawl 85 provided on the support rod 15. As shown in Fig. In the illustrated example, the rotary member 30 can rotate in the counterclockwise direction, but when it tries to rotate clockwise, the pawl 85 engages the ratchet gear 80 to prevent rotation. And prevents the purifying module 40 from rotating in the clockwise direction through the direction control means.

It goes without saying that a conventional one-way clutch structure can be applied as the direction control means in addition to the structure shown in the figures. In this case, the one-way clutch is provided between the rotary member and the support bar so that the rotary member can rotate only in one direction.

In another embodiment of the present invention, a water level countermeasure means may be provided to allow the purification module 40 to move up and down when the water level changes.

If the purification module can not move up and down according to the water level, operation may not be possible when the water level of the lake, bay, estuary area, dam, reservoir, pond, farm etc. fluctuates. For example, if the water level is high, the purifying module can be immersed in water, and if the water level is low, the purifying module is floated from the water surface, making it impossible to operate.

Therefore, according to the present invention, the purifying module can be configured to be movable up and down according to the water level, so that the water can be continuously operated even if the water level fluctuates.

6, a first hinge engaging part 34 provided on the rotary member 30 and hinged to one side of the connecting bar 31, a housing 43 of the float 41 And a second hinge engaging part 44 hinged to the other side of the connecting bar 31.

By hinging both sides of the connecting bar 31, the purifying module 40 can move up and down when the water level changes. For example, when the water level drops from A to B as shown in FIG. 6, the purification module 40 is lowered from the A level to the B level.

Another example of the water level countermeasure means is shown in Fig. And has a structure of a connecting bar made up of a plurality of joints as a water level countermeasure means.

For example, the connection bar may include a first bar 101 connected to the rotary member 30, a second bar 105 hinged to one side of the first bar 101, And a third bar 109 hinged to the other side of the second bar 101.

Another example of the water level countermeasure means is shown in Fig. Referring to FIG. 8, the water level countermeasure means is coupled to the support rod 15 and has a floating portion 90 for moving the support rod 15 up and down according to the water level.

In the embodiment of FIG. 8, the support rod 15 is not fixed to the float 10 but is coupled so as to be vertically movable. That is, the float 10 is provided with a lift hole 12 penetrating vertically. The support rod 15 is inserted into the lift hole 12. The diameter of the support rod 15 is formed to be smaller than the diameter of the lift hole 12. The vertical length of the support rod 15 is formed to be larger than the vertical length of the float 10. At the lower end of the support rod 15, a stopper 16 having a larger diameter than the lift hole 12 is provided. The supporting rod 15 inserted into the lift hole 12 can be moved up and down by the floating 90. In order to prevent the support rod 15 from rotating when the support rod 15 is moved up and down, a guide groove may be formed on the outer circumferential surface of the support rod 15 up and down. In this case, a coupling protrusion coupled to the guide groove may be formed on the inner side of the lift hole 12. Further, the support bar 15 between the floating portion 90 and the stopper 16 can be formed in a rectangular shape. In this case, the lift hole 12 is formed to be a square having a larger cross-sectional area than the support rod 15.

The floating portion 90 is located at the lower portion of the rotary member 30. The floating portion 90 is fixedly coupled to the support rod 15. The floating portion 90 is filled with a buoyancy material so as to float on the water surface or is formed into a hollow structure in which the inside is hollow. The floating portion 90 is always floated on the water surface. The floating portion 90 coupled to the support rod 15 floats on the water surface, so that the rotary member 30 is always positioned above the water surface.

When the water level fluctuates and the floating section 90 moves up and down along the water level, the supporting rod 15 coupled with the floating section 90 also moves up and down. Therefore, the purifying module coupled with the rotary member 30 by the connection bar 31 can also move up and down according to the water level. FIG. 8 shows a state in which the support portion descends while the floating portion 90 moves downward when the water level falls from A to B. FIG.

As described above, according to the present invention, since the purification module can move up and down according to the water level by the water level countermeasure, the purification operation can be continuously performed even when the water level fluctuates.

6 to 8 are the same as those of the embodiment shown in Figs. 1 to 3, and thus detailed description thereof will be omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention. . Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
