위를 더욱 자세하게 설명하면 다음과 같다.The above is described in more detail as follows.

먼저 본 발명에 따른 양수파이프 연결용 커플링(10)은 단위 길이의 양수파이프(P)를 길이방향으로 연결하기 위한 것으로, 중공의 몸체(12) 내측에 양수파이프(P1,P2)를 결합하기 위한 연결수단이 구비되고 외측에는 다수개의 날개(16)가 일체로 형성된다.First, the positive pipe connection coupling 10 according to the present invention is for connecting the positive pipe P having a unit length in the longitudinal direction, and combining the positive pipes P1 and P2 inside the hollow body 12. Connection means for the provided and a plurality of wings 16 are formed integrally outside.

여기서 본 발명에 따른 상기 커플링(10)은, 몸체(12)의 내측 중간부에 돌출테(14)가 형성되며, 상기 돌출테(14)의 상부에 암나사(15)를 형성하여 양수파이프(P1)와 나사로 조립하고, 하부에는 양수파이프(P2)를 삽입하여 용접하도록 된 것을 특징으로 한다.Wherein the coupling 10 according to the present invention, the protruding frame 14 is formed in the inner middle portion of the body 12, the female thread (15) is formed on the upper portion of the protruding frame (14) pumping pipe ( P1) and the screw, and the lower portion is characterized in that the welding pipe (P2) by inserting.

다시 말해, 상기 커플링(10)은 양수파이프의 연결수단으로 몸체(12)의 내측 중간부에 소정의 돌출테(14)를 형성하여 양수파이프(P1,P2)의 끝단면이 접촉하고, 상기 돌출테(14)의 하부에 양수파이프(P1)를 삽입하여 용접 등의 접합수단에 의해 강인하게 접합되며, 상부에는 암나사(15)를 형성함으로써 양수파이프(P2)와 나사로 체결한다. 물론 상기와 같은 용접, 나사 등의 방법들을 치환하거나 선택적으로 병행할 수도 있다.In other words, the coupling 10 forms a predetermined protruding frame 14 in the inner middle portion of the body 12 as a connecting means of the positive pipes so that the end surfaces of the positive pipes P1 and P2 are in contact with each other. The pump pipe (P1) is inserted into the lower portion of the protruding frame (14) to be firmly joined by joining means such as welding, and the upper part is fastened with the pump (P2) by screwing the female screw (15). Of course, the above-described methods such as welding, screw may be substituted or optionally combined.

상기 몸체(12)의 외측에는 다수개의 날개(16)를 일정한 간격을 두고 방사상으로 형성하여 양수파이프(P)가 시추공(100)의 암벽에 접촉 및 충돌하지 않도록 한다.On the outside of the body 12, a plurality of wings 16 are formed radially at regular intervals so that the pump pipe (P) does not contact and collide with the rock wall of the borehole 100.

한편 본 발명의 상기 날개(16)는 4~8개가 일정 간격으로 구성됨을 특징으로 하며, 상기의 날개(6)가 6개로 이루어지는 것이 가장 바람직하다.On the other hand, the wings 16 of the present invention is characterized in that 4 to 8 are configured at a predetermined interval, it is most preferable that the wing 6 is made of six.

상기 날개(16)에는 요입홈(18)을 형성하고 상기 몸체의 외측에 수중전선(W)을 감을 수 있게 함에 따라, 상기의 수중전선(W)이 느슨해지지 않도록 함은 물론 엉기거나 꼬이는 현상을 방지하여 손상되지 않도록 한다.As the wing 16 forms a recess groove 18 and allows the underwater wire W to be wound on the outside of the body, the underwater wire W is not loosened as well as tangled or twisted. To prevent damage.

또한 본 발명에 따른 상기 날개(16)는 유선형으로 이루어진 것을 특징으로 한다. 즉 상기의 날개(16)가 각진 모서리가 없이 유선형으로 부드러운 곡면을 이루어짐에 따라, 양수파이프(P)가 시추공(100) 속으로 삽입될 때 시추공 내벽과의 접촉이나 간섭을 줄이고 원만하게 진행할 수 있도록 한 것이다.In addition, the wing 16 according to the present invention is characterized in that the streamlined. That is, as the wing 16 has a smooth curved surface without angled edges, when the positive pipe P is inserted into the borehole 100, the contact or interference with the inner wall of the borehole can be reduced and progress smoothly. It is.

이뿐만 아니라 본 발명의 상기 날개(16)는 위로 갈수록 협소하게 구성되어 있어서, 양수파이프 및 커플링이 시추공(100) 속을 삽입될 때 날개의 윗부분에 다소의 유격을 두어 마찰력을 최소화하고 보다 원활하게 삽입되게 한다. 이와 함께 상기 양수파이프를 시추공으로부터 인양시 더욱더 용이하게 한다.
In addition, the wing 16 of the present invention is narrower toward the top, so that the pump and the coupling is inserted into the borehole 100 to minimize the friction and smoothly put a little play on the upper part of the wing To be inserted. Along with this, the pump may be more easily lifted from the borehole.

아울러, 상기한 본 발명의 실시 예를 들어서 구체적으로 설명하였지만, 본 발명의 기술적 범위를 한정하려는 것은 아니며, 본 발명이 속한 기술 분야에서 통상의 기술을 가진 당업자에게 본 발명을 보다 명확하고 용이하게 설명하려는 것이며, 치환, 변경, 개량이 가능하다.
In addition, the embodiments of the present invention have been described in detail, but are not intended to limit the technical scope of the present invention, and the present invention will be more clearly and easily described by those skilled in the art having ordinary skill in the art. It is intended to be substituted, modified, and improved.
