본 고안은 댐 및 저수지의 수질개선을 위한 수중폭기장치에 관한 것으로, 기존의 간헐식 압축공기 공급방식과는 달리 연속적인 양수 및 수표면 확산을 동시에 실시하여 수질을 효과적으로 개선하고 태양광 에너지를 일반 전력을 교체사용할 수 있도록 함으로써 이의 가동에 소요되는 에너지비용을 최소화할 수 있도록 한 것이다.The present invention relates to an underwater aeration device for improving the water quality of dams and reservoirs. Unlike conventional intermittent compressed air supply methods, the present invention performs continuous pumping and surface diffusion at the same time, effectively improving water quality and improving solar energy. By making the power available for replacement, it minimizes the energy cost of its operation.

지금까지 사용된 간헐식 수중폭기기는 도 1에 도시된 바와 같이 수중 양수통(2) 하부에 고정용 앵커(3)와 공기실(1)을 설치하고 육상에 설치된 압축기에서 만들어진 압축공기를 배관(도시 안 됨)을 통하여 공기실(1)에 공급하며, 이 공기실(1)이 충만되면 폭기하여 폭기시 상승하는 공기탄의 부력으로 심층수를 양수하여 수표면에 확산하는 구조로 되어 있었다.As shown in FIG. 1, the intermittent submersible apparatus used up to now has a fixing anchor 3 and an air chamber 1 installed at the bottom of the water pump 2, and the compressed air made by the compressor installed on the land is piped. It was supplied to the air chamber 1 (not shown), and when this air chamber 1 was full, it aerated and pumped deep water by the buoyancy force of the air coal rising at the time of aeration, and spreading it on the water surface.

도면 중 부호 4는 부구이다.In the figure, 4 is a sub-ball.

따라서, 종래의 수중폭기장치는 별도의 수전설비와 공기압축기실을 설치하여야 하며, 고무호스를 통한 압축공기의 송기시 상당한 에너지손실이 발생하여 비경제적이고, 또한 공기가 공기실에 충만되면 자동으로 폭기하여 심층수를 양수하는 간헐식 폭기기로서 양수된 심층수를 수표면에 확산하는 기능이 없어 양수량에 비하여 수질개선효과가 그다지 높지 않은 단점이 있었다.Therefore, the conventional submersible aeration apparatus should be equipped with a separate power receiving facility and air compressor chamber, and a considerable energy loss occurs when the compressed air is sent through the rubber hose, which is uneconomical and automatically aerated when the air is filled to the air chamber. As an intermittent aeration system that pumps deep water, there is no function to diffuse the deep water on the surface of the water, so the water quality improvement effect is not so high compared to the amount of pumped water.

본 고안은 종래의 수중폭기장치와는 반대로 양수 및 수표면 확산을 동시에 할 수 있는 패들형 순환펌프를 수중 양수통의 상부 수표면에 설치하여 적은 양수량으로 호소의 수질을 개선하고 태양광 에너지와 일반 전력을 상호 교체사용하므로 에너지 사용을 효율적으로 할 수 있는 개선된 구조의 수중폭기장치를 제공하는 데 있다.The present invention is to install a paddle type circulation pump that can simultaneously pump and water surface diffusion in contrast to the conventional underwater aeration system on the upper surface of the water reservoir to improve the water quality of the appeal with a small amount of water, and to improve the solar energy and general The present invention provides an underwater aerator with an improved structure, which can efficiently use energy by using power interchangeably.

이와 같은 목적을 달성하기 위하여 본 고안은 수표면에서 심층수를 양수 및 확산하는 2가지 기능을 가진 패들형 순환펌프와 디퓨저로 이루어진 수중폭기장치를 설치하여 에너지 사용효율을 극대화하고, 이 순환펌프는 태양광전기와 일반 전력을 상호 교체하여 사용할 수 있도록 한 수중폭기장치를 제공한다.In order to achieve the above object, the present invention installs an underwater aeration device consisting of a paddle type circulation pump and a diffuser having two functions of pumping and diffusing deep water from the surface of the water to maximize energy use efficiency, and the circulation pump An underwater aerator is provided to allow the interchange of photoelectric and general power.

The lower end of the pump 20 is connected to the fixed anchor 30.

상기 양수통(20)의 하단부에는 여과망(26)이 설치되어 있어 양수통(20) 내부로 크기가 큰 이물질이 유입되는 것을 방지함으로써 장치의 고장발생을 예방할 수 있도록 되어 있다.The lower end of the reservoir 20 is provided with a filter net 26 is to prevent the occurrence of a malfunction of the device by preventing the large foreign matter flowing into the reservoir 20.

또한, 상기 양수통(20)의 상단부 외측에는 양수통(20)이 자립할 수 있도록 부력관(28)이 씌워져 있으며, 양수통(20)의 최상단부에는 펌프 케이싱(52)이 플랜지결합되어 있다.In addition, the buoyancy pipe 28 is covered on the outside of the upper end of the pump 20 so that the pump 20 can be self-supporting, the pump casing 52 is flanged to the upper end of the pump 20. .

상기 패들형 순환펌프(50)는 펌프 케이싱(52)의 내측에 유체의 흡입을 양호하게 하기 위한 석션 가이드(54; suction guide)가 설치되어 있고, 펌프 케이싱(52)의 상단부에는 순환펌프 모터(70)의 축에 결합된 임펠러(56)가 설치되어 있다.The paddle-type circulation pump 50 is provided with a suction guide (54) for improving the suction of the fluid inside the pump casing 52, the upper end of the pump casing 52, the circulation pump motor ( An impeller 56 coupled to the shaft of 70 is provided.

The pumping action is generated by the 56b, 56c) and the water in the reservoir 20 is pumped up, so that deep water can be pumped.

또, 상기 임펠러(56)는 물의 확산을 크게 하기 위하여 물결형의 파형을 일으키게 되는데, 반원형의 날개(56b,56c)가 서로 엇갈리게 배치된 상태에서 저속으로 회전하게 되므로 기존의 압축기를 사용하는 수중폭기장치에 비하여 전력사용량을 최소화할 수 있는 것이다.In addition, the impeller 56 generates a wave form in order to increase the diffusion of water, the semi-circular wings (56b, 56c) are rotated at a low speed in a state where they are staggered from each other, the underwater aeration using a conventional compressor The power consumption can be minimized compared to the device.

상기 임펠러(56)의 형태는 도 3에 도시된 바와 같은 형태에 한정되지 않으며, 날개를 더 많게 제작할 수도 있음은 물론이다.The shape of the impeller 56 is not limited to the shape as shown in FIG. 3, and of course, more wings may be manufactured.

또, 상기 임펠러(56) 위에는 임펠러(56)에 의해 퍼올려진 심층수를 수표면으로 확산시키기 위한 접시형태의 확산 보조용 디퓨저(60)가 설치되어 있는데, 이 확산 보조용 디퓨저(60)의 상면에는 도 4에 도시된 바와 같이 방사상으로 리브(62)가 형성되어 있어 물의 회전력을 차단하고 임펠러(56)에 의해 퍼올려진 심층수가 어느 한 방향으로 편중되지 않고 전방향으로 고르게 확산될 수 있도록 보조해주게 된다.Further, on the impeller 56, a dish-shaped diffusion assisting diffuser 60 is provided for diffusing the deep water pumped by the impeller 56 onto the water surface. An upper surface of the diffusion assisting diffuser 60 is provided.

한편, 본 고안의 수중폭기장치를 구동하기 위한 전력은 육상에 설치된 태양광 발전설비(100; 도 5 참조)에서 케이블(도시 안 됨)을 사용하여 순환펌프 모터(70)에 연결되고, 태양광 전기를 사용할 수 없을 경우에는 일반 전력을 교체 사용할 수 있도록 하면 된다.On the other hand, the electric power for driving the underwater aeration apparatus of the present invention is connected to the circulation pump motor 70 using a cable (not shown) in the photovoltaic power generation equipment 100 (see FIG. 5) installed on land, and the solar light If you do not have access to electricity, you can replace the utility power.

도 5에 도시된 태양광 발전설비(100)는 솔라셀(110)과 배터리(120) 및 충전 제어기(130)와 직류전원을 교류전원으로 전환하기 위한 인버터(140)를 포함하여 이루어져 있다.The photovoltaic power generation device 100 illustrated in FIG. 5 includes a solar cell 110, a battery 120, a charge controller 130, and an inverter 140 for converting DC power into AC power.

또한, 본 발명에서 상기 패들형 순환펌프(50)의 흡입측에 약품 투입구(80)를 설치하여 필요시 수질개선을 위한 각종 약품을 살포할 수 있도록 되어 있다.In addition, in the present invention, by installing the chemical inlet 80 on the suction side of the paddle-type circulation pump 50, it is possible to spray various chemicals for water quality improvement if necessary.

이와 같이 구성된 본 고안은 수표면에 설치된 패들형 순환펌프(50)가 일반 전력이나 태양광 발전설비(100)에서 발전한 전력을 이용하여 지속적으로 구동하게 되는 것이며, 이에 의해 양수관(20)을 통해서 댐이나 저수지 등의 심층수를 퍼올리게 되고, 순환펌프(50)에 의해 퍼올려진 심층수는 디퓨저(60)를 통해 어느 한 방향으로 편중되지 않고 사방으로 고르게 그리고 넓은 면적으로 확산되게 되므로 적은 전력소모만으로도 높은 수질개선효과를 볼 수 있게 되는 것이다.The present invention configured as described above is that the paddle-type circulation pump 50 installed on the water surface is continuously driven by using the power generated from the general power or the photovoltaic power generation facility 100, thereby through the pump pipe 20 Deep water, such as dams and reservoirs, is pumped up, and the deep water pumped up by the circulation pump 50 is diffused evenly in all directions and spreads in all directions through the diffuser 60. High water quality improvement effect will be seen.

이상 설명한 바와 같이 종래의 수중폭기기는 대용량의 압축공기를 공급하여 간헐적으로 심층수를 양수하여 폭기하는 단순한 구조로 되어 확산면적에 비하여 전 력을 많이 소비하게 되는 문제점이 있었으나, 본 고안의 수중폭기장치는 수표면에서 양수와 표면확산을 동시에 할 수 있는 패들형 순환펌프로 연속적으로 작동하므로 확산효과가 크고 적은 양수량으로 넓은 면적의 수질을 개선할 수 있으며, 특히 전력사용량이 소량이므로 태양광 전기와 일반 전력을 상호 교체하여 사용할 수 있어서 에너지 절감효과가 큰 실용적인 효과를 갖는다.As described above, the conventional underwater aeration machine has a problem in that it consumes a lot of electric power compared to the diffusion area because it has a simple structure of supplying a large amount of compressed air and intermittently pumping deep water. Since it operates continuously as a paddle type circulation pump that can pump and surface diffuse simultaneously on the water surface, it has a large diffusion effect and can improve the water quality of a large area with a small amount of water. Since the power can be used interchangeably, the energy saving effect has a large practical effect.
