Description

TECHNICAL FIELD [0001] The present invention relates to a water circulation apparatus for preventing or reducing green tide or red tide,

The present invention relates to a water circulation apparatus for preventing or reducing algae or red tide, and more particularly, to a water circulation apparatus for effectively preventing stratification in a water to prevent and inhibit the formation of a habitat environment of algae causing green tide or red tide, To a water circulation device capable of reducing the power consumption required by the water circulation device.

In the waters of the water-saving environment in which nutrients such as nitrogen and phosphorus are continuously introduced from various pollutants, eutrophication phenomenon occurs due to a disproportionately increasing number of specific elements.

The eutrophication phenomenon reproduces algae and phytoplankton (hereinafter "algae"), and these breeding birds overexploit with dissolved oxygen in the water, causing a green tide or red tide. Particularly, when the sunlight is strong and the temperature rises, the stratification phenomenon becomes more intense as the surface waters of lake water are intensively heated. As a result, the surface water becomes an ideal environment in which the algae live. Of course, the surge of algae further accelerates the algae or harmonization phenomenon of the area.

These green tides and red tides reduce the amount of dissolved oxygen in the water as well as changes in the color of the water, causing the death of fish and shellfish, etc., and the above-mentioned dead organisms occur in a chain in the biological group, thereby destroying the ecosystem of the surrounding area as well as the water. In addition, when water quality is deteriorated due to the occurrence of green tide or red tide in the lake water used as drinking water, the water quality of the lake water becomes difficult and the water amount of drinking water is also reduced.

In order to overcome this problem, a physical, chemical and biological control method has been proposed to limit eutrophication, temperature rise and sunlight, which cause habitat environment of algae causing green tide and red tides.

Conventional chemical / biological control methods include a loess spraying method for inducing flocculation and sedimentation of algae, a fungicide spraying method for algae sterilization, a phosphorus adsorption method using silicate dendritic agent, and a method for flocculation and flooding of algae Methods of spraying natural coagulants, an aquamat method for increasing microbial activity rates for nitrogen and phosphorus removal, and aquatic planting methods for absorbing nitrogen and phosphorus and blocking sunlight in water. Conventional physical control methods include a method of collecting algae using an algae removing line, a method of discharging a low water for preventing water stagnation, a method of water circulation in water, a method of installing algae inflow prevention film, a spraying method, And the method of generating microbubbles for disturbance, the sunlight blocking method for preventing photosynthesis of algae, and the method of installing livestock manure disposal plant or sewage treatment plant upstream to limit the inflow of nutrients into lake water.

However, since the conventional chemical / biological method is a post-pollution technology, it is difficult to perform pre-pollution control, the control range is local, and damage to existing ecosystems is limited.

On the other hand, in the conventional physical control method, there is a limitation that the installation method of the algae inflow prevention film and the sunlight blocking method are very limited in scope and limit the habitat environment of the existing ecosystem so that the application thereof is limited. Therefore, there is a limit to the application area and time, and the number of lake water that can be applied to the livestock manure treatment plant or the sewage treatment plant is extremely limited. In addition, the method of collecting and collecting algae using the algae elimination line was not continuous and continuous control, and the pre - control function was insignificant. In the microbubble generation method, the utilization efficiency was low because the algae flooding and disturbance range were local and temporary. In addition, the water circulation method in water is a method of transferring relatively low-temperature low-temperature water to the surface layer and transferring the relatively high-temperature surface water to the low-temperature water. By circulating the surface water and the low water layer, disturbing the stratum of the lake water and dispersing the eutrophication components, Since the formation of habitat is inhibited, the increase of algae causing green tide and red tide can be prevented in advance, and the algae and red tide phenomenon can be reduced even after.

However, in the conventional water circulation system, since a large amount of water must be circulated continuously in water, a relatively high-output apparatus and a circulating apparatus having a complicated facility structure are required, and high power consumption is inevitable for continuous operation of the circulating apparatus. As a result, the conventional water circulation system can not continuously drive for pre-treatment due to the expensive circulation device and the maintenance cost, although the water must be circulated continuously. If the water circulation is not continued, And it had to be local.

The water circulation apparatus M of the present embodiment includes an air pipe 311 for injecting air into water; An air bucket 210 formed into a cap shape so as to collect the air bubble A generated through the air pipe 311; A pumping bucket 220 formed in a cap shape so as to move together with the movement of the air bucket 210 and carry water in the water; And a guide frame (100) in which at least one of the air bucket (210) and the pumping bucket (220) is movably mounted and guided.

The air pipe 311 is communicably connected to the air pump 310 so that air in the air pumped by the air pump 310 is pumped into the water so that the air bucket 210 located in the water collects the air. Although the air pipe 311 is connected to the air pump 310 in the present embodiment, the compressed air in the air tank is connected to the air tank 311 (not shown) So that the air bucket 210 can be collected.

The air bucket 210 has a cap shape. When the opening part is downwardly positioned in the water, the air pipe 311 collects the air bubbles A injected into the water. If the opening part is in an upward position, Exhausted. The posture of the air bucket 210 in which the opening portion is upward can be taken not only in water but also in water or water.

The pumping bucket 220 has a cap shape and is connected to the air bucket 210 so that the air bucket 210 moves in the water due to the upward force received by the air bucket 210. The pumping buckets 220 may be arranged adjacent to each other so as to be paired with the air buckets 210. Alternatively, the pumping buckets 220 may be disposed at a distance from each other, and the number of the pumping buckets 220 and the air buckets 210 may be mismatched .

The pumping bucket 220 is made of a material having the same or similar shape and specific gravity as the air bucket 210. Since the pumping bucket 220 is intended to carry water in water unlike the air bucket 210, Thereby establishing an opposed connection. The pumping bucket 220 adjacent to the air bucket 210 is positioned in a position where the opening portion is raised upward so that the low layer water can be taken up to the surface layer Lt; / RTI >

The air bucket 210 and the pumping bucket 220 are not limited to specific gravity but the air bucket 210 and the pumping bucket 220 may be formed of a flexible connecting line L having a specific gravity smaller than that of water. It is preferable that at least one of the air bucket 210 and the pumping bucket 220 is made of a material having a specific gravity larger than that of water so that the air bucket 210 and the pumping bucket 220 do not rise in water by their own weight. Accordingly, the air bucket 210 collects the air bubble A to generate a rising force, and moves together with the pumping bucket 220 with this power.

The guide frame 100 guides movement by mounting at least one of the air bucket 210 and the pumping bucket 220 so that the pneumatic bucket 210 and the pumping bucket 220 connected to each other as described above are supported by the air bucket 210 And moves along the guide frame 100 along the water due to the upward force generated in the guide frame 100. [ Since the airbag 210 and the pumping bucket 220 of the present embodiment are connected to each other in an endless track manner and the guide frame 100 also has an annular shape corresponding to the airbag 210 and the pumping bucket 220, (220) repeats rotation in the water.

More specifically, the guide frame 100 of the present embodiment includes a bucket transfer pipe 110 installed to receive and guide at least one air bucket 210; The air pipe 311 is mounted on the guide frame 100 so that air can be injected into the bucket transfer pipe 110.

The bucket transfer pipe 110 of the present embodiment is an annular pipe and is installed so as to terminate the surface layer and the bottom layer in water, and an air bucket 210 and a pumping bucket 220 are movably mounted in the hollow. A first opening 111 is formed in an upper portion of the surface layer of the bucket conveying pipe 110 so that the air introduced into the hollow of the air bucket 210 and the bucket conveying pipe 110 and the low- A second opening 112 is formed in a lower portion of the lower portion of the bucket conveying pipe 110 so that the surface layer water flowing into the hollow of the bucket conveying pipe 110 is discharged and the lower layer water is introduced.

Accordingly, the air bucket 210 is moved in the bucket transfer pipe 110 by the upward force by the air injected through the air pipe 311, and the pumping bucket 220 is moved by the upward force applied by the air bucket 210, 2, and the surface layer water flowing into the hollow through the first opening 111 is transferred to the lower layer.

A plurality of air buckets 210 and a pumping bucket 220 are connected to the hollow of the bucket conveying pipe 110 through a connection line L to generate circulating water in the bucket conveying pipe 110, The surface waters and bottom waters of lake water are maintained in a continuous cycle.

For reference, the air pump 310 may be of the engine type such as gasoline or diesel, but in the present embodiment, the air pump 310 is an electric motor type. The air pump 310 performs a pumping function for forcibly introducing the air in the air into the air pipe 311, and the power for driving is supplied from the replaceable battery and the rechargeable battery. The water circulation apparatus M of the present embodiment is supplied with electric power from the rechargeable battery 330 and the rechargeable battery 330 is charged with the solar power generation utilizing the solar cells 340 and 340 '. The solar cells 340 and 340 ', the rechargeable battery 330, the charger 320 and the air pump 310 are installed on the barge line 400 so that the guide frame 100 of the water circulation device M is installed The guide frame 100 may be connected to the barge line 400 via the brackets 130 and 130 'having the rope 131 connected to the barge line 400, .

The barge line 400 is also connected to one or more anchors 440 and 440 'via a wire 441 to maintain the barge line 400 in position at the lake water.

As described above, the guide frame 100 of this embodiment is disposed such that the first opening 111 of the bucket conveying pipe 110 is exposed to the water surface. Therefore, the low-level water conveyed along the bucket conveying pipe 110 is drained through the first opening 111, and the surface water flows in through the first opening 111. The air bucket 210 and the pumping bucket 220 are partially exposed to the water surface as shown in FIG. 3 (a) while moving along the bucket transfer pipe 110. In this process, And the surface water is contained in the pumping bucket 220. Further, the pumping bucket 220 forms a water flow along the bucket transfer pipe 110 to continuously circulate the surface water and the low water. When the pumping bucket 220 is partially exposed to the surface of the water, the air is introduced into the pumping bucket 220 and the pumping bucket 220 is pushed into the bucket conveying pipe 110 (see FIG. 3 The air flowing into the pumping bucket 220 can be introduced into the bucket transfer pipe 110 along with the movement of the pumping bucket 220. [ Therefore, the pumping bucket 220 is kept in the pumping bucket 220 until the pumping bucket 220 is released from the first opening 111 so that the air introduced into the pumping bucket 220 is pushed to the atmosphere by the water pressure in the state of being exposed to the first opening 111, It is desirable that the inner bottom surface of the pumping bucket 220 be maintained in an inclined posture in the atmospheric direction.

FIG. 4 is a cross-sectional view schematically showing a second embodiment of a water circulation apparatus according to the present invention, and FIG. 5 is a perspective view showing a partial cross-sectional view in which the pumping bucket shown in FIG. 4 is fixed to a sliding block.

Thus, the air bucket 210 and the pumping bucket 220 move along the guide rail 120 together with the sliding block 121.

5, the slit 124 is formed in the joint section between the bucket transfer pipe 110 and the guide rail 120, and the slit 124 is formed in the joint section between the guide rail 120 and the bucket transfer pipe 110. [ So that the hollows of the bucket conveying pipe 110 and the guide rail 120 are communicated with each other. Since the linker 122 for fixing the sliding block 121 to at least one of the air bucket 210 and the pumping bucket 220 passes through the slit 124, 210 and the sliding block 121 moving along the pumping bucket 220 and the guide rail 120 move smoothly without interfering while maintaining a fixed state between them.

The guide frame 100 'of the present embodiment includes an annular guide rail 120, a plurality of sliding blocks 121 mounted movably along the guide rails 120, and a sliding block 121 And a gap support body (123) accommodated between adjacent sliding blocks (121) so as to be arranged; At least one of the air bucket 210 and the pumping bucket 220 is fixed to the sliding block 121. That is, the present embodiment constitutes one or more gap supports 123 between neighboring sliding blocks 121, so that the sliding blocks 121 are arranged apart from each other, through which the neighboring air buckets 210 ) Are arranged apart from each other.

The plurality of air buckets 210 and the pumping buckets 220 are arranged at regular intervals along the bucket transfer pipe 110 so that the low layer water and the surface layer water of the lake water are also accelerated at constant pressure and speed, It causes oil.

FIG. 6 is a cross-sectional view schematically showing a third embodiment of the water circulation apparatus according to the present invention, and FIG. 7 is a perspective view showing a partial cross-sectional view in which the pumping bucket shown in FIG. 6 is fixed to the sliding block.

The bucket conveying pipe 110 of the guide frame 100 " is disposed only in a part of the annular guide rail 120. Therefore, The air bucket 210 and the pumping bucket 220 move along the hollow of the bucket conveying pipe 110 in a part of the guide rail 120 and are exposed to the outside in other sections.

Thus, the water circulation device (A) of the present embodiment does not limit the circulating flow of lake water to the bucket transfer pipe (110), and induces circulation of surface water and low water in a relatively wide range.

FIG. 8 is a perspective view showing another embodiment of the pumping bucket and the air bucket according to the present invention, FIG. 9 is a perspective view showing a sectional view of the pumping bucket and the air bucket shown in FIG. 8, 1 is a cross-sectional view showing the operation of the illustrated pumping bucket and air bucket.

The water circulation apparatus M of the present embodiment further includes a spacer 230 provided between the pumping bucket 220 and the air bucket 210 such that the pumping bucket 220 and the air bucket 210 are spaced apart from each other . Further, the pumping bucket 220 is formed with a valve hole 221 opened toward the air bucket 210 so that air can be discharged; A hood valve (240) is provided to control the opening and closing of the valve hole (221).

In the present embodiment, the hood valve 240 includes a hood 241 which is opened and closed in accordance with the forward and backward movement toward the valve hole 221; And a guide stopper 242 connected to the hood 241 so as to guide the movement of the hood 241. Here, the guide stopper 242 of this embodiment includes a hinge rotatably mounted on at least one of the air bucket 210, the pumping bucket 220, and the spacer 230.

The structure of the pumping bucket 220 and the air bucket 210 according to the present embodiment will be described in more detail. The pumping bucket 220 and the air bucket 210 are arranged such that the pumping bucket 220 and the air bucket 210 are spaced apart from each other. The spacing 230 is further provided between the pumping bucket 220 and the air bucket 210. The spacing 230 is further provided between the pumping bucket 220 and the air bucket 210,

Subsequently, the pumping bucket 220 of the present embodiment forms a valve hole 221 toward the air bucket 210 so that air can be discharged, and the valve hole 221 is opened and closed by the hood valve 240. 9 (a), when the hood valve 240 is closed and the valve hole 221 is closed, the pumping bucket 220 can not be vented or watered in the direction of the air bucket 210, when the hood valve 240 is opened and the valve hole 221 is opened as shown in the drawing, water or air located in the pumping bucket 220 can be discharged in the direction of the air bucket 210 through the valve hole 221 .

The hood valve 240 of this embodiment comprises a hood 241 for opening and closing the valve hole 221 and a guide stopper 242 for guiding the movement of the hood 241. The guide stopper 242 May be a hinge type. The hinge-type guide stopper 242 is provided on the pumping bucket 220. However, if the hood 241 can be mounted to open and close the valve hole 221, the air bucket 210 and the spacer 230). ≪ / RTI >

The operation of the hood valve 240 according to the present embodiment will be described with reference to FIG.

As shown in FIG. 10 (a), the air bucket 210 collects the air injected by the air pipe 311 to form a relatively low specific gravity, and the pumping bucket 220 has a water holding posture. At this time, since the hood 241 is made of a material having a specific gravity relatively larger than that of water, the hood 241 covers the valve hole 221 by its own weight. Therefore, the pumping bucket 220 is lifted up to the surface layer of the lake water by the upward force of the air bucket 210 while maintaining the water-filled state.

10 (b), when the air bucket 210 and the pumping bucket 220 descend to the lower layer of the lake water, the pumping bucket 220 assumes a downward orientation, The hood 241 located at the center moves around the guide stopper 242 by its own weight, through which the valve hole 221 is opened. Therefore, the air remaining in the pumping bucket 220 is discharged to the outside through the valve hole 221. The resistance generated during the downward movement of the pumping bucket 220 is reduced through the smooth passage of the valve hole 221 so that the demand force of the earset 210 and the pumping bucket 220 Can be saved.

11 is a cross-sectional view showing another embodiment of a pumping bucket and an air bucket according to the present invention.

The guide stopper 240 'of this embodiment includes a moving bar 243 fixed to the hood 241; And a guide binding hole 244 provided on at least one of the air bucket 210, the pumping bucket 220, and the spacer 230 so as to guide the translational movement of the moving bar 243.

More specifically, the guide stopper 240 'of the present embodiment includes a moving bar 243 protruding from the hood 241 toward the air bucket 210. The movable bar 243 is fixed to the hood 241 and moves together with the hood 241. [ The moving bar 243 of the present embodiment is in the shape of a tube, and a flange 243a protrudes from the end.

The guide stopper 240 'of this embodiment includes a binding hole 244 connected to the moving bar 243 so as to guide the translational movement of the moving bar 243. The binding joint 244 of this embodiment is fixed to the air bucket 210 and inserted into the tubular movable bar 243 in a piston structure to guide the movement of the movable bar 243. At this time, a stopping protrusion 244a that engages with the flange 243a protrudes at the distal end to prevent the movement bar 243 from coming off. As a result, the movable bar 243 can be translationally moved to a position where the engaging jaw 244a of the binding hole 244 is located. In this process, the movable bar 243 and the fixed hood 241 move together, (Not shown).

The operation of the air bucket 210 and the pumping bucket 220 constituting the guide stopper 240 'will be described in more detail. As shown in FIG. 11 (a) 311 collects the injected air to form a relatively low specific gravity, and the pumping bucket 220 forms a water holding posture. At this time, since the hood 241 is made of a material having a specific gravity relatively larger than that of water, the hood 241 covers the valve hole 221 by its own weight. Therefore, the pumping bucket 220 is lifted up to the surface layer of the lake water by the buoyant force of the air bucket 210 while keeping the water filled state.

11 (b), when the air bucket 210 and the pumping bucket 220 descend to the lower layer of the lake water, the pumping bucket 220 assumes a downward posture, The hood 241 located is lowered by its own weight, through which the valve hole 221 is opened. In this process, the hood 241 and the fixed moving bar 243 move along the binding opening 244, and the movement of the moving bar 243 is stopped by the flange 243a of the moving bar 243 being engaged with the engaging jaw 244a of the binding opening 244 As shown in Fig. Therefore, the air remaining in the pumping bucket 220 is discharged to the outside through the valve hole 221. The resistance generated during the downward movement of the pumping bucket 220 is reduced through the smooth passage of the valve hole 221 so that the required power of the earset 210 and the pumping bucket 220 Can be saved.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
