Description

Aeration equipment for water quality and green algae improvement using wind power}

The present invention relates to an aeration device for preventing algae and improving water quality using wind power, and more particularly, is installed in rivers or reservoirs to form a myriad of vortices to increase the amount of dissolved oxygen, and also to accelerate the flow of stagnant water. The present invention relates to an aeration device for preventing algae and improving water quality using wind power used to prevent water pollution.

In rivers, reservoirs, ponds, and fish farms, nutrients such as nitrogen and phosphorus increase due to decomposition of organic matter by microorganisms, causing eutrophication, which causes abnormalities such as green algae. If this occurs, the fish are dead or difficult to use as drinking water.

In addition, in the case of a reservoir or a pond in which the flow velocity is slow or the water is stagnant, the oxygen is not supplied to the bottom of the water at all, and the water is rapidly polluted.

Therefore, apparatuses for improving the water quality by supplying oxygen into the water have been developed. As such an example, Japanese Patent Laid-Open No. 11-179392 (wind quality improvement device by wind power) is disclosed.

The technique of this document raises the water in the water by the wind and improves the water quality by driving the pump as needed to eject the compressed air into the water, but to drive the pump, power is required to drive the pump separately. Even if there are no facilities for supplying power to the surroundings, such as rivers, it simply functions to raise the water in the water by the wind, and as a result, the efficiency of water quality drops sharply.

In addition, there is a problem that the foreign matter in the water rises while the water in the bottom of the water rises to impinge on the stirring blade or wound on the stirring blade, the normal operation is inhibited or the stirring blade is broken.

On the other hand, as another prior art is disclosed in Korean Patent Laid-Open Publication No. 2009-79119 (floating water purification device), the technique of this document is a housing 100 floating on the water surface as shown in Figure 1, The wind driving means 110 is installed in the housing 100 and consists of a shroud 120 having a length below the housing 100.

The technique of this document is that the propeller installed inside the shroud 120 is rotated so that the water in the bottom of the water rises to the surface along the shroud 120, so that a separate generator is installed to rotate the propeller to generate wind or solar power. It is difficult to reduce the weight of these components because the solar collector module, generator, etc., which are very complicated in structure and are difficult to be installed in the water because they are generated at the upper part based on the housing 100, are generated as a result of the strong wind. If a large eddy current occurs or there is a problem that the housing 100 can be easily reversed.

When the housing 100 is turned upside down so that the shroud 120 is exposed to water, the function cannot continue, and there is a difficulty that the operator has to flip the housing 100 again.

In addition, when the fan is rotated through the wind, a force is generated to rotate together with the housing 100 in the rotation direction of the fan, whereby the rope 130 is wound around the outer circumferential surface of the shroud 120 to cause abnormal operation. have.

In addition, as in the prior art, there is a possibility that the foreign matter, pollutants, seaweeds, etc. in the water may be damaged by the propeller, and the operation of simply raising the water at the bottom of the water increases the amount of dissolved oxygen in the water. The efficiency is significantly lowered, and there is a fear that the float easily enters the top of the shroud 120 and the inlet part may be blocked.

Therefore, the present invention has been made to solve the problems of the prior art as described above, the operation is not inhibited by foreign matter or suspended matter, it is possible to increase the amount of dissolved oxygen without using a separate external power, and automatically posture An object of the present invention is to provide an aeration device for preventing algae and improving water quality using wind power that is not turned over by control.

An object of the present invention as described above is aeration body, the through-hole is formed through the central region is vertically penetrated, the floating body is formed with a sealed receiving space for storing air therein; An air inlet pipe installed at a bottom of the floating body; A support housing installed on an upper surface of the floating body and provided with a sealed space in which air is stored so that the floating body maintains its posture by buoyancy; An upper end is coupled to a lower end of the air inlet pipe, and a plurality of water inlet holes are formed in which water inflows along the upper side circumference and has a length downwardly toward the bottom of the water; It is supported by the support housing, has a length that passes through the air inlet pipe and the air discharge pipe in turn, by blowing the external air of the water into the air inlet pipe by the rotational operation to mix the outside air with water, A blade assembly for generating a vortex and discharging it to the bottom of the water; It is achieved by configuring a rotating power generating unit coupled to the upper portion of the blade assembly to rotate the blade assembly by wind power.

At this time, the weight of the support housing and the rotary power generating unit installed on the upper side of the floating body is greater than the sum of the sum of the air inlet pipe, the air discharge pipe and the blade assembly installed on the lower side of the floating body. It can be implemented by making it small.

And the air inlet pipe and the main pipe body of the cylindrical hopper shape that the communication hole is connected up and down; It may be implemented as consisting of an auxiliary blade that is provided in a plurality radially on the outer surface of the main pipe body.

In addition, the blade assembly is a shaft; A blow blade having a plurality of radially installed on an upper outer circumferential surface of the shaft; It is installed on the lower side of the blow blade and may be implemented as consisting of a vortex generating blade is provided with a plurality of radially along the length of the shaft.

The support housing may further include an increaser configured to increase the rotational speed generated by the rotational power generating unit at a predetermined ratio and provide the blade assembly to the blade assembly.

According to the present invention, one or more plural can be installed and operated in rivers or reservoirs, and since rotational power is generated by wind power, there is no restriction in the place of installation because it does not supply external power by separately connecting a power line.

And it can be operated by moving the installation position freely according to the degree of contamination.

In addition, since numerous vortices are formed and the outside air is introduced and mixed with the water, the amount of dissolved oxygen is increased, and as a result, the water quality is improved.

In addition, when the flow rate is installed in a stream, the flow rate of water is improved due to the numerous vortices generated through the vortex generating blade, and as a result, it is possible to prevent various water pollution caused by the slow or stagnant flow rate.

Hereinafter will be described in more detail with reference to the accompanying drawings showing a preferred embodiment.

The present invention relates to an aeration device that is installed to improve the water quality of rivers, reservoirs and farms using wind power, which is largely floating body 10, air inlet pipe 20 as shown in FIG. ), The support housing 30, the air discharge pipe 40, the blade assembly 50 and the rotational power generating unit 60.

The floating body 10 is formed in a ring-shaped tube shape as shown in Figure 5 (a, b) is formed with a through hole 11 through which the central region penetrates up and down, the inside is sealed to store air The receiving space 12 is formed thereby buoyancy is generated to rise on the water surface, at this time by installing a rope with an anchor on the bottom of the water, the floating body 10 can be installed to float a certain radius around the anchor. have.

As shown in FIG. 6, the air inlet pipe 20 installed on the bottom surface of the floating body 10 to communicate with the through hole 11 has a shape of upper and lower narrow, that is, a cylindrical hopper shape. 21A) is formed of a main pipe body 21 and the auxiliary blade 22 is provided with a plurality of radially along the outer peripheral surface of the main pipe body (21).

The main pipe body 21 blows the external air on the water to the lower side by the blowing plate 52 when the blade assembly 50, which will be described later, rotates, flowing to the lower portion having a diameter smaller than the upper diameter. The discharge pressure of the outside air is increased, and as a result, the outside air and water are more easily mixed and discharged into the water.

And the auxiliary blade 22 is a force to be rotated together in the direction of rotation of the rotating power generating unit 60 when the floating power generating unit 60 to be described later is rotated at high speed by the wind power. When the force to rotate the floating body 10, the auxiliary blade 22 is rotated along the floating body 10 to form a relatively large vortex on the water surface.

This is because another vortex is formed on the water in addition to the vortices caused by the water discharged with the external air toward the bottom of the water through the blade assembly 50, which will be described later, resulting in a slow or stagnant water in the water surface and underwater Multiple vortices continue to occur, resulting in a rapid improvement in water flow.

The support housing 30 installed on the upper surface of the floating body 10 supports the shaft 51 of the blade assembly 50, which will be described later, and at the same time, the aeration device 1 according to the present invention has a posture caused by strong wind or rapid flow. Even if reversed, it also serves to quickly return to the original position.

The support housing 30 for this is fixed to the upper surface of the body portion 31 and the main body 31 and the main body 31 having a closed space 31A therein as shown in Figure 7 (a) It consists of a plurality of support portion 32 and the installation portion 33 formed on the upper surface of the main body portion 31 to form an inlet of the appropriate size so that the outside air flows into the air inlet pipe 20, the installation portion As shown in FIG. 7B, a thrust bearing 34 coupled to the shaft 51 is installed to support the load of the shaft 51 while enabling rotational operation.

At this time, the thrust bearing 34 is the upper bearing 34A is fixed to the shaft 51 by welding or bolt, etc., the lower bearing 34B is fixed to the installation portion 33, the upper bearing 34A and the lower bearing A plurality of rollers R may be provided between the 34Bs.

And by increasing the rotational speed provided from the rotational power generating unit 60 by varying the rotational ratio of the shaft 51 installed to penetrate up and down inside the support housing 30 to increase the performance of the blowing air. have.

In this example, the shaft 51 is divided into upper and lower shafts (not shown), the upper power shaft is provided with a rotational power generating unit 60, the lower shaft is blown blades 52 and vortex generating blades described later on the outer peripheral surface 53 may be formed, and the speed increaser G having a constant speed ratio may be installed according to the gear ratio of gears of different sizes that are interlocked between upper and lower shafts.

The upper end is coupled to the lower end of the air inlet pipe 20 and the air discharge pipe 40 having a length downward toward the bottom of the water, as shown in Figure 8 (a) a plurality of water inlet holes (a) along the periphery of the upper side ( 41 is formed, the flange 42 is assembled to the top corresponding to the flange 23 formed on the lower end of the air inlet pipe 20.

As such, the air discharge pipe 40 has an upper portion connected to the air inlet pipe 20 and an open portion at the lower portion thereof, except for the water inlet hole 41 and the open end of the lower portion thereof. It does not have a structure.

Due to this structure, when the blade assembly 50 to be described later rotates in the air inlet pipe 20 and the air discharge pipe 40, the pressure for blowing air downward and the pressure for discharging water downward act on the air discharge pipe ( 40) while the water inside is quickly discharged to the lower portion, while the inside of the limited amount is introduced through the water inlet hole 41, the water level inside the air discharge pipe 40 naturally lower than the external water level, as a result of the blade assembly ( The resistance (load) of the water to rotate 50 is reduced so that the rotational motion of the blade assembly 50 continues and the faster the rotational speed, the easier the rotational motion of the blade assembly 50 becomes.

And since the water inlet hole 41 is formed at a position spaced apart from the water surface, there is no fear that foreign substances injured on the water surface may be introduced, and even if foreign substances on the bottom of the water are injured, the water inlet hole 41 is not introduced into the water inlet hole 41 of limited size. As a result, the blade assembly 50 is not exposed to suspended matter or foreign matter, thereby extending its lifespan.

And the air discharge pipe 40 is communicated up and down, the lower portion may be further provided with a nozzle 45 for discharging the air discharged with water at a higher pressure.

The nozzle 45 is installed in the center of the nozzle body portion 45A and the nozzle body portion 45A provided at the lower end of the air inlet pipe 20 as shown in FIG. It includes a plurality of discharge holes (45C) penetrating up and down the shaft mounting portion (45B) and the nozzle body portion (45A) is seated on the lower end.

The nozzle 45 is prevented from entering the outside foreign matter into the air inlet pipe 20 and at the same time through the plurality of discharge holes (45C) relatively high pressure water and the outside air is mixed and discharged a little more underwater The vortex can be delivered to the area close to the bottom, and the dissolved oxygen is rapidly increased because the external air mixed with water is discharged to rise from the area close to the bottom in the water.

The blade assembly 50, which is supported by the support housing 30 and has a length that sequentially passes through the air inlet pipe 20 and the air discharge pipe 40, and generates vortices by a rotation operation, is illustrated in FIG. 9. Likewise, a plurality of blow blades 52 are radially installed on the shaft 51, an upper outer circumferential surface of the shaft 51, and a plurality of blow blades 52 are disposed below the blow blades 52 and are radially disposed along the length of the shaft 51. It is composed of a swirl generating blade 53 is installed.

At this time, the blowing blade 52 is installed in accordance with the shape of the air inlet pipe 20 blades of the upper and lower narrow installation is carried out by inhaling the outside air by the rotational operation to blow air downward into the air inlet pipe (20). do.

And the vortex generating blade 53 is implemented as a blade having a downward length for discharging the air mixed with water to the lower side while countless vortices are formed by the rotation operation, this also by the vortex generating blade 53 The water and air inside the air discharge pipe 40 is carried out with an angle-adjusted blade to receive the force discharged toward the bottom of the water.

The rotary power generating unit 60 coupled to the upper portion of the blade assembly 50 has an axial coupling portion 61 coupled to the upper portion of the blade assembly 50, that is, the shaft 51, as shown in FIG. Wings which are respectively installed at the ends of the plurality of connecting portions 62 and the connecting portion 62 radially along the outer circumferential surface of the coupling portion 61 and are installed to rotate in one direction about the shaft coupling portion 61 by wind power. Part 63 may be implemented.

At this time, the wing 63 may be implemented in various forms for those skilled in the art to increase the rotational efficiency by the wind.

The aeration device 1 of the present invention configured as described above, when the rotary power generating unit 60 is rotated by the wind as shown in Figure 11, the shaft 51 is rotated while the air inlet pipe 20 inside The blowing plate 52 and the vortex generating blades 53 installed inside the air discharge pipe 40 are rotated together, thereby blowing the outside air to the air discharge pipe 40 through the air inlet pipe 20, At the same time, the water inside the air discharge pipe 40 is rotated at a high speed, vortices are generated to mix the outside air, and the water mixed with the outside air is strongly discharged toward the bottom of the water, and then bubbles are naturally floated.

At the same time, while the rotational operation of the shaft 51 is continued, the water in the water is introduced into the air discharge pipe 40 through the water supply hole 41 and is mixed with the external air and then discharged.

On the other hand, the present invention is operated in a state of being injured on the water surface, the injured body 10 may be inclined or inverted due to strong winds or rapids, such as inverted, even in this case, quickly returned to the first installed position to continue aeration operation It is desirable to.

Therefore, in the present invention, the air inlet pipe 20 having the weight of the support housing 30 and the rotary power generating unit 60 installed on the upper side of the floating body 10 is installed on the lower side of the floating body 10. ) And the air discharge pipe 40 and the blade assembly 50 is performed to be smaller than the combined weight, for this purpose, a plurality of weights may be installed at the front end or lower outer peripheral surface of the air discharge pipe 40.

As described above, air is stored in the closed space 31A of the support housing 30 so that buoyancy acts together when the support housing 30 is submerged.

As a result, as shown in FIG. 12, even if the posture is inclined or reversed by rapids or strong winds, the self-weight and buoyancy act together to quickly return to a posture where normal operation is possible, thereby allowing the operator to maintain the installation. It is easier to have.

On the other hand, the aeration device 1 of the present invention, as shown in Figure 13 can be operated at the same time by installing a plurality of on the surface according to the width of the river or reservoir and fish farm, in this case each aeration device (1) When the installation range is set so that the ranges for generating vortices do not overlap, and the anchor is lowered to the bottom of the water to fix the position, the floating body 10 freely floats a proper radius around the anchor to improve the water quality within a certain radius. In the case where a plurality of aerators 1 are installed, the installation interval is preferably adjusted in consideration of the floating radius of the floating body 10.

In addition, if necessary, by connecting a rope or the like to the rear of the power boat to pull the floating body 10, the rotational power generating unit 60 can be naturally rotated by the wind, whereby the floating body 10 is a certain range It can also be used to quickly improve water pollution while moving within a contaminated area.

In this way, the floating body 10 may float on the water surface and float freely. Therefore, when the floating body 10 has difficulty in normal operation such as winter season or there is a fear of damage such as a typhoon, the aeration device 1 installed on the water surface is powered by a boat. The damage can be prevented beforehand by recovering the product to a safe place using, for example.

The present invention as described above is installed in rivers, reservoirs, farms, etc. by the wind power to obtain a rotational power by the wind power to form a myriad of vortices in the water and at the same time supply the outside air into the water, the dissolved oxygen amount is increased to improve the water quality, Since the flowability of water due to vortex is improved, various water pollutions caused by slow flow rate or stagnation of water are prevented.
