DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 6, an apparatus for removing greenhouse water using small hydroelectric power according to an embodiment of the present invention includes a river guiding unit 100, a river supplying unit 200, a small hydroelectric generating unit 300, A downstream shade forming means 400, and a river purifying means 500.

The river guiding means 100 is provided on the river to guide the river downstream in the upstream direction. The river guiding means 100 is installed to be inclined upstream in the downstream of the river, and the inner space through which the river flows is contacted with the air, And a solar panel for supplying electric energy to the river supply means 200 so that a shadow is formed in the inner space by covering the sunlight with the sunlight being provided on the upper part of the waterway 110, (120).

The water channel 110 is inclined from the downstream toward the upstream, and the inner space is opened upward, so that the river guided along the inner space is in contact with the air, so that oxygen can be supplied from the air.

A backflow prevention portion 111 for preventing the backflow of the river supplied by the river supply means 200 is formed on the inlet side of the water channel 110. The backflow prevention portion 111 is formed in a plate shape and is installed on the inlet side of the water channel 110.

In addition, the flow channel 110 is formed with a flow portion 130 for flowing the guided river. The moving part 130 may be a jaw protruding from the inner space of the water channel. That is, since the river moves upward and downward while being jolted up to the upper part while passing over the jaw of the moving part 130, it is moved in a stirred state, so that oxygen can be easily supplied to the river by contacting with a large amount of air.

As described above, when a river mixed with oxygen by the water channel 110 is provided upstream, the amount of dissolved oxygen in the upstream is increased, thereby preventing the death of aquatic organisms. Furthermore, oxygen is supplied to aquatic plants that consume phosphorus and nitrogen, and oxygen is also supplied to microorganisms that decompose pollutants, so that green algae can be reduced. That is, the river can be cleanly cleaned by supplying oxygen.

Particularly, when the downstream river is supplied upstream by the water channel 110, the upstream river flows downstream, and the river is circulated as a whole, so that the water temperature rise is suppressed. As the increase in water temperature is suppressed, not only the number of microorganisms causing green algae is reduced but also the death of aquatic organisms can be prevented.

In addition, the water channel 110 may be provided with water jets 140 provided at predetermined intervals to spray water. This water jet 140 injects the water pumped by an external pump. That is, since the river sprayed from the water jet 140 is supplied to the river conveyed along the river guiding means 100, the river to be moved is stirred so that not only the air is mixed but also the river moves smoothly.

Since the shade is formed in the inner space of the water channel 110 by the solar panel as the shade forming member 120, it is possible to prevent the photosynthesis from occurring in the green tide included in the moving river. That is, an increase in the green tide can be prevented. That is, the solar panel can produce shadows at the same time as electric energy is produced.

In particular, when the solar panel is installed at 10 to 20 km along the river, since the amount of electric energy generated is large, one or two pumps described later can operate for 24 hours. Since the river supplying means 200 does not use the commercial power by using the electric energy of the solar panel, the electric energy can be saved. Of course, the waterway 110 located at the lower part of the solar panel may be installed at 10 to 20 km along the river.

Here, the channel 110 and the shade forming member 120 may be fixed to the frame 150. The frame 150 includes a plurality of pillars standing upright in the river bed and a reinforcing shaft horizontally connected to the pillars. Therefore, the water channel 110 and the shade forming member 120 are vertically spaced from each other in the frame 150. [

One side of the river feeding means 200 includes oxygen supplying means 160 which is constituted by a blow to supply oxygen to the downstream river which is pulled up and fixed to the frame 150. The downstream river can be supplied by the river supply means 200 in a state where the oxygen supply means 160 supplies oxygen in the water downstream of the river. Thereby, the amount of dissolved oxygen in the downstream river and the amount of dissolved oxygen can be supplied upstream.

The river supply means 200 includes a pump for lifting and supplying the river to the river guiding means 100 and a hose to which one end is connected to the pump and the other end is connected to the river guiding means 100 . The pump can be electrically connected to the solar panel to be operated by electric energy generated from the solar panel described above. Further, the river supplying means 200 may be configured to be supplied with commercial power. Thus, when the pump is pumped, the river can be discharged through the hose and supplied to the river guiding means 100.

The small hydropower generation means 300 is connected to the river guiding means 100 and generates electrical energy by using the river to be guided and discharged. The small hydroelectric generating means 300 guides the river discharged from the river guiding means 100 to an inner space A rotating body 320 which is rotatably provided in the inner space of the power generating tube 310 and is rotated by a falling falling body and a rotating body 320 which is rotated by the rotating body 320 And a power generation unit 330.

The inner space of the power generation tube 310 is opened at both ends. Here, the power generation pipe body 310 is vertically or inclinedly installed at one end thereof in communication with the river guide means 100 and at the other end thereof in communication with the river purification means 500. As a result, the river flowing into the inner space of the power generating tube 310 can be dropped at a rapid rate.

The rotating body 320 is formed in a screw shape, one end is fixed to the inner space of the power generating tube 310 so as to idle, and the other end is connected to the power generating part 330.

The power generation unit 330 is composed of a permanent magnet fixed to the rotating body 320 and a coil close to the permanent magnet.

Therefore, when a river flows into the inner space of the power generating tube 310, the falling river rotates the rotating body 320, so that the power is generated in the power generating unit 330 to produce electric energy. Here, the electric energy to be generated can be supplied to the river supply means 200 or the oxygen supply means 500.

The downstream shade forming means 400 forms a shade by hiding sunlight on a river downstream of the river supplying means 200. The shade forming means includes a float forming a shade floating on the water surface, Includes floating government to prevent movement.

The floating body is composed of a plurality of air balls floating on the water surface, and the floating body is composed of a mesh in which a plurality of error balls are accommodated. Therefore, if the downstream shade forming means 400 is floated downstream, a shade can be formed downstream.

The river purifying means 500 purifies and discharges the water used for power generation in the small hydroelectric generating means 300, and includes a screen filter 510 for removing contaminants from the incoming river, and a sludge contained in the incoming river, (530) for repeatedly aerating and precipitating the treated water in the first separating tank (520), and a first treatment tank (530) for treating the treated water in the first treatment tank A lower sedimentation tank 540 for sludge sedimentation and anaerobicization and a lower sedimentation tank 550 for returning the lower sludge precipitated in the final sedimentation tank 540 to the initial separation tank 520, And an aeration tank 560 that receives the supernatant from the final sedimentation tank 540 and induces stable discharge.

First, the river purifying means 500 is formed such that the above-described tanks 510, 530, 540, and 560 are successively connected successively so that the river can be sequentially filled. The river purifying means 500 is constructed of synthetic resin to float on the river and the river is installed on the outer side so that the river is filled in each of the tanks 510, 530, 540 and 560, . ≪ / RTI > Further, the river purification means 500 can be prevented from being lost by being fixed to the above-mentioned frame 150 so as to prevent the drainage.

The screen filter 510 is formed in a mesh shape and is disposed between the initial separating tank 520 and the river purifying means 500 to filter the river discharged from the small hydroelectric generating means 300 to filter out the contaminants.

The screen filter 510 is installed on the upper portion of the initial separating tank 520 in an inclined state and flows down along a slope when there are many contaminants such as a green tide. A dewatering net 511 is provided in the lower portion of the screen filter 510 to remove debris from the dirt. In other words, when the dewatering net 511 is dewatered with the contaminants, the dewatering net 511 can be easily removed because it becomes a cake.

In the first separation tank 520, foreign matter such as sludge is deposited on the bottom due to the inflow of the river, so that the supernatant is overflowed and transferred to the batch treatment tank 530.

The batch treatment tank 530 is provided with a contact agent 531 in which a microorganism is cultured therein and an air diffuser 532 for supplying air. Therefore, since the river introduced from the first separating tank 520 is decomposed by the microorganisms of the contact agent 531, and microorganisms can be actively proliferated by the oxygen contained in the air supplied from the air diffuser 532, A foam removing unit 533 for removing foam generated by the air supplied from the engine 532 is provided. The contact agent 531 may be composed of a lidar made of a plastic container containing microorganisms. The air diffuser 532 may be configured as a blow which supplies outside air into the water. The foam removing unit 533 may be configured to include a pump and a nozzle so as to pump and spray the water supplied from the aeration type discharge tank 560.

The final settling tank 540 is filled with the treated sludge in the batch treatment tank 530 and the sludge is settled.

The lower conveying unit 550 includes a transfer pipe installed from the bottom of the final settling tank 540 to the initial separating tank 520 and a transfer pump for pumping the transfer pipe connected to the transfer pipe. Accordingly, when the transfer pump is operated, the lower water located at the bottom of the final settling tank 540 can be supplied to the initial separation tank 520 through the transfer pipe. Thus, a completely uncleaned lower portion is fed back to the batch treatment tank 530 and can be perfectly cleaned.

The aeration tank 560 may be discharged only in the supernatant after the overflowing effluent from the final sedimentation tank 540 is filled. At this time, an aeration tube for supplying oxygen to the microorganisms contained in the river may be installed in the aeration tank 560, and a discharge pump 561 for discharging the purified river may be installed. Therefore, the river can be discharged upstream of the river in the aeration tank 560.

The river purifying means 500 can be installed between the river guiding means 100 installed at predetermined intervals along the river to clean the river to be transported. Here, the purified water pumped by the discharge pump 561 can be supplied to the other river guiding means 100 to the river purifying means 500 located between the river guiding means 100.

Thus, the river purified by the river purification means 500 is supplied upstream, so that the river can be cleaned as a whole.

As described above, the present invention is a very useful invention that can be widely applied to an apparatus for preventing green tide since the river can be cleaned by supplying the downstream river to the upstream to circulate the river to supply oxygen to the river can do.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the above description is intended to be illustrative, and not restrictive, and that the scope of the present invention will be defined by the appended claims rather than the foregoing description, All changes or modifications that come within the scope of the equivalent concept are to be construed as being included within the scope of the present invention.
