먼저, 도 1 및 2에 도시한 바와 같이 본 발명은 크게 물 위에 띄울 수 있도록 된 부력수단(10)과, 부력수단(10)의 상부에 탑재된 모터부(20)와, 모터부(20)로부터 동력을 제공받아 그 임펠러(35)가 회전함에 따라 물의 흡입과 토출이 이루어지도록 부력수단(10) 하부에 설치된 양수부(30)와, 양수시 부력수단(10)이 부유하는 것을 방지하고 수위에 따라 수직방향으로 승강할 수 있도록 안내하기 위한 가이드 수단(40)이 구비된다.First, as shown in FIGS. 1 and 2, the present invention provides a buoyancy means 10 that can be floated on water, a motor part 20 mounted on the buoyancy means 10, and a motor part 20. As the impeller 35 rotates to receive the power from the pumping unit 30 installed below the buoyancy means 10 so that the suction and discharge of water is performed, and the buoyancy means 10 is prevented from floating while the water level is raised. According to the guide means 40 for guiding to be elevated in the vertical direction is provided.

더욱 상세하게는, 부력수단(10)은 그 상면에 모터부(20)를 장착할 수 있도록 체결용 플레이트(21)가 마련되고 모터부(20)의 축에 임펠러(35)를 축 결합할 수 있도록 양수부(30) 측으로 축 공(11)이 천공되며 그 외주면을 따라 삽입 틀(12)이 형성된 장착판(10a)과, 장착판(10a)의 삽입 틀(12)에 그 상부가 삽입 장착되고 양수부(30)가 하향 돌출되도록 그 내측에 양수부(30)를 수용하기 위한 수용홈(13)이 형성된 부력 부재(10b)로 이루어진다. 여기서 부력 부재(10b)는 스티로폼 또는 그 내 부에 공기가 충전된 에어 팩 등 물에 뜰 수 있는 재질이면 족하다. More specifically, the buoyancy means 10 is provided with a fastening plate 21 for mounting the motor unit 20 on the upper surface thereof and can be coupled to the shaft of the impeller 35 to the shaft of the motor unit 20. The shaft hole 11 is drilled toward the pumping portion 30 so that the mounting plate 10a is formed along the outer circumferential surface thereof and the upper portion is inserted into the insertion frame 12 of the mounting plate 10a. And it is made of a buoyancy member (10b) formed with a receiving groove 13 for receiving the pumping portion 30 inside the pumping portion 30 so as to project downward. Here, the buoyancy member 10b may be a material that can float on water such as styrofoam or an air pack filled with air therein.

또한, 양수부(30)는 그 저면이 밀폐되되 그 내측 하부에 임펠러(35)를 수용하기 위한 케이싱(31)이 마련되고 임펠러(35)의 회전에 따라 물을 흡입할 수 있도록 케이싱(31)에 대응하는 양수부(30)의 저면에 흡입공(32)이 천공되며 흡입된 물을 토출할 수 있도록 양수부(30) 상측에 토출관(33)이 형성된다. In addition, the pumping portion 30 is provided with a casing 31 for accommodating the impeller 35 at the bottom of the bottom surface thereof is sealed, and the casing 31 to suck water according to the rotation of the impeller 35. The suction hole 32 is drilled in the bottom surface of the pumping unit 30 corresponding to the discharge pipe 33 is formed above the pumping unit 30 to discharge the sucked water.

전술한 기술적 구성에 따르면, 모터부(20)의 구동에 의해 임펠러(35)가 회전하고, 임펠러(35)의 회전에 의해 물은 양수부(30)의 저면에 천공된 흡입공(32)을 통해 케이싱(31)으로 흡입되어 토출관(33)으로 토출된다. 이때, 임펠러(35)의 회전으로 케이싱(31) 내로 유입된 물은 토출관(33)으로 토출되기 전에 일시 양수부(30) 내에 체류하게 되고, 이때 비중이 무거운 모래 알갱이나 이물질 등은 원심력에 의해 케이싱(31) 외측으로 이동한 후 가라앉게 된다. According to the above-described technical configuration, the impeller 35 is rotated by the driving of the motor unit 20, and the water is sucked by the rotation of the impeller 35. It is sucked into the casing 31 and discharged to the discharge pipe 33. At this time, the water introduced into the casing 31 by the rotation of the impeller 35 stays in the temporary pumping portion 30 before being discharged to the discharge pipe 33, wherein the sand grains and foreign matters having a specific gravity are subjected to centrifugal force. As a result, the casing 31 moves outward and then sinks.

즉, 염전지나 정화조, 배수조의 수위가 낮아 양수시 모래알갱이나 이물질이 양수부내로 유입되더라도 케이싱(31)과 원심력에 의해 외측으로 분리됨으로써 이들 이물질이 토출관(33)을 통하여 토출되는 것을 방지할 수 있게 된다. In other words, even when sand grains or foreign substances are introduced into the pumping part when the water level of the salt cell, the septic tank, or the drainage tank is low, they are separated outward by the casing 31 and the centrifugal force to prevent the discharge of these foreign substances through the discharge pipe 33. It becomes possible.

또한, 양수로 인하여 수위가 낮아지면 그에 따라 부력수단(10)이 하강하게 된다. 이때, 부력수단(10)은 가이드 수단(40)에 의해 안내됨으로써 수면에서의 부유를 방지할 수 있게 된다. 그 결과, 수위에 따라 양수장치가 수직방향으로 승강함으로써 용이하게 양수작업을 실시할 수 있게 된다. In addition, when the water level is lowered due to pumping, the buoyancy means 10 is lowered accordingly. At this time, the buoyancy means 10 is guided by the guide means 40 can prevent the floating on the water surface. As a result, the pumping device is lifted in the vertical direction in accordance with the water level, so that the pumping work can be easily performed.

더욱 상세하게는, 가이드 수단(40)은 저수조의 바닥에 고정 설치된 지주(41)와, 지주(41)를 따라 수직방향으로 승강할 수 있도록 부력수단(10)에 지주 안착 홈(42)이 형성된다. 본 발명의 도 1에서는 부력수단(10)의 양측에 지주 안착홈(42)을 형성하고 그 지주 안착홈(42)에 지주(41)가 내설된 것으로 도시하였으나 지주 안착홈(42)을 다각형으로 형성하고 그 지주 안착홈에 다각형의 지주를 내설시킬 경우 하나의 기둥만으로도 양수장치의 부유를 방지할 수 있게 된다.More specifically, the guide means 40 has a support 41 fixed to the bottom of the reservoir and a support seating groove 42 is formed in the buoyancy means 10 so that the guide means 40 can be elevated in the vertical direction along the support 41. do. In FIG. 1 of the present invention, the support seating grooves 42 are formed on both sides of the buoyancy means 10, and the support seats 41 are illustrated in the support seating grooves 42, but the support seating grooves 42 are polygonal. When forming and insulated polygonal struts in the strut seating grooves it is possible to prevent the floating of the pumping device with only one column.

결과적으로, 본 발명에 따른 양수장치는 물 위에 뜬 상태에서 양수를 실시함으로써 양수부(30)가 염전지나 정화조, 배수조의 바닥으로부터 떨어져 있어 이물질 내지 토사의 유입을 방지할 수 있다. 또한, 수위가 변하더라도 항상 수면에 떠 있는 상태를 유지함으로써 양수작용을 원활하게 수행할 수 있다. As a result, in the pumping device according to the present invention, the pumping unit 30 is separated from the bottom of the salt cell, the septic tank, or the drainage tank by performing the pumping in the state of floating on the water, thereby preventing the inflow of foreign matter or the soil. In addition, even when the water level is changed, it is possible to smoothly perform the pumping action by keeping the surface floating at all times.

상기의 기술적 구성에 따르면, 양수부가 부력수단의 하부에 설치된 상태이므로 스크루식 회전날개가 수중에 위치하게 되고, 스크루식 회전날개가 회전함에 따 라 물은 상방향으로 밀어 올려져 토출관을 통해 토출되게 된다. According to the above technical configuration, since the pumping part is installed in the lower portion of the buoyancy means, the screw type rotary blade is located in the water, and as the screw type rotary blade rotates, the water is pushed upward and discharged through the discharge pipe. Will be.
