상기 유도관 연결구(120)는 관체로 된 토출구(121)의 후단에 상측으로는 경사면(122)이 형성되며, 하측으로는 걸림턱(123)이 돌출되어 형성된다.The induction pipe connector 120 is formed with an inclined surface 122 on the rear end of the discharge port 121 made of a tubular body, and a locking step 123 protrudes from the lower side thereof.

그러므로, 토출구(121)의 전단이 취수관(110)의 내측으로부터 끼워져서 외측으로 노출되며, 경사면(122)과 걸림턱(123)은 취수관(110)의 내측에 위치하면서 토출구(121)의 이탈을 방지하게 된다.Therefore, the front end of the discharge port 121 is inserted from the inside of the intake pipe 110 and exposed to the outside, the inclined surface 122 and the locking jaw 123 is located inside the intake pipe 110, This prevents the departure.

밀착지지부(130)는 취수관(110)내에서 상기 유도관 연결구(120)의 대향된 위치에 설치되는데, 사각 박스 형태의 하우징(131)이 취수관(110)의 외측으로 돌출되도록 구비되고, 상기 하우징(131)의 내측에서 가로방향으로 회전축(132)이 지지되어 설치된다.The close support 130 is installed at the opposite position of the induction pipe connector 120 in the intake pipe 110, the rectangular box-shaped housing 131 is provided to protrude out of the intake pipe 110, The rotating shaft 132 is supported in the horizontal direction from the inside of the housing 131 is installed.

또한, 상기 회전축(132)상에는 이를 매개로 하여 상하 방향으로 회동하는 회동편(133)이 구비되는데, 상기 회동편(133)의 면은 가운데 부분이 안쪽으로 약간 절곡되도록 하여, 이후 유도관(140)의 몸체가 면 접촉되면서 쉽게 장착이 가능하도록 한다.In addition, on the rotating shaft 132 is provided with a rotating piece 133 to rotate in the vertical direction via this, the surface of the rotating piece 133 is to be slightly bent inward to the center portion, then the induction pipe 140 ) Body can be easily contacted with the surface contact.

상기 회동편(133)의 하부에는 걸림턱(134)이 돌출 형성되어 있어서 이에 유도관(140)이 안착되어 지지되도록 한다.A locking jaw 134 is protruded from the lower portion of the pivoting piece 133 so that the guide tube 140 is seated and supported.

한편, 유도관(140)의 장착시에 회동편(133)의 상부가 유도관(140)과의 간섭을 배제하기 위하여 하우징(131)의 내측에 위치하고, 회동편(133)의 하부는 하우징(131)의 외측 즉, 취수관(110)쪽으로 더 돌출되도록 하기 위해 회동편(133)의 하측 후면과 하우징(133)의 내측 사이에는 스프링(135)이 장착된다.On the other hand, at the time of mounting the guide tube 140, the upper portion of the rotating piece 133 is located inside the housing 131 to exclude the interference with the guide tube 140, the lower portion of the rotating piece 133 is the housing ( A spring 135 is mounted between the lower rear side of the rotating piece 133 and the inner side of the housing 133 so as to protrude further toward the outer side of the 131, that is, the intake pipe 110.

상기 스프링(135)은 하우징(131)의 내측에 형성된 홀더(136)와 회동편(133)의 하측 후면에 형성된 홀더(137)에 양측이 삽입되어 고정되어 회동편(133)의 하측을 탄성지지하게 되는 것이다. Both sides of the spring 135 are inserted into and fixed to the holder 136 formed on the inner side of the housing 131 and the holder 137 formed on the lower rear surface of the rotating piece 133 to elastically support the lower side of the rotating piece 133. Will be done.

유도관(140)은 펌프로부터 펌핑된 지하수를 유입받기 위한 입수구(141)가 형성되어 있으며, 측면으로는 배수구(142)가 형성되어 있어서 펌핑된 지하수를 90도 방향으로 유도시켜 토출구(121)를 통하여 물탱크쪽으로 배출되도록 한다.Induction pipe 140 is formed with an inlet 141 for receiving the pumped ground water from the pump, the drain port 142 is formed on the side to guide the pumped ground water in a 90 degree direction discharge outlet 121 Through the water tank.

한편, 배수구(142)의 반대쪽에는 밀착지지부(130)에 거치되기 위하여 유도관(140)의 몸체가 후방으로 돌출되어 형성된다.
On the other hand, the opposite side of the drain port 142 is formed to protrude rearward the body of the guide tube 140 to be mounted on the close support 130.

이러한 구조를 갖는 종래 기술의 장착 및 탈착 과정을 설명한다.The mounting and detaching process of the prior art having such a structure will be described.

먼저, 장착시는 유도관(140)이 취수관(110)의 내부에서 상부로부터 하향 이동하게 되면, 배수구(142)가 형성된 부분이 유도관 연결구(120)의 경사면(122)을 타고 후방 즉, 밀착지지부(130) 쪽으로 이동하게 된다.First, when the induction pipe 140 is moved downward from the inside in the intake pipe 110 at the time of mounting, the portion formed with the drain port 142 is rearward, that is, the inclined surface 122 of the induction pipe connector 120, It moves toward the close contact portion 130.

이때, 밀착지지부(130)의 회동편(133)은 스프링(135)에 의하여 하부가 취수관(110)의 내측으로 돌출되고, 상부는 하우징(131)의 내측에 위치하도록 되어 있어서, 유도관(140)의 후단이 간섭없이 회동편(133)의 중심부로부터 면접촉되어 하향 이동하게 되고, 회동편(133)이 회동하여 회동편(133)의 상부가 세워지면서 도 2와 같이 유도관(140)의 후단 상부와 접촉하게 된다.At this time, the rotating piece 133 of the close support 130 is protruded into the lower portion of the intake pipe 110 by the spring 135, the upper portion is to be located inside the housing 131, the induction pipe ( The rear end of the 140 is moved face down from the center of the rotating piece 133 without interference, the rotating piece 133 is rotated to raise the upper portion of the rotating piece 133, as shown in FIG. It comes into contact with the upper part of the rear end of the.

즉, 유도관(140)의 후단 하측이 회동편(133)의 하부를 면접촉하면서 누르게 되면, 회동편(133)의 상부가 회동되어 유도관(140)의 후단 상측을 유도관 연결구(120)쪽으로 밀게 된다.That is, when the rear end lower side of the induction pipe 140 is pressed while the surface contact the lower portion of the rotating piece 133, the upper portion of the rotating piece 133 is rotated to guide the upper end of the rear end of the guide pipe 140 induction pipe connector 120 Pushed towards.

한편, 상기 유도관(140)의 전단과 후단은 각각 유도관 연결구(120)의 걸림턱(123)과 밀착지지부(130)의 걸림턱(134)에 안착되어 지지되며, 하우징(131)의 바닥에는 걸림돌기(138)가 형성되어 있어서, 유도관(140)의 장착시에 회동편(133)이 하우징(131)의 내측으로 밀려 들어가는 것을 방지함으로써 유도관(140)이 취수관(110)의 내측에서 하부로 이탈되는 것을 방지하게 되는 것이다.On the other hand, the front and rear ends of the induction pipe 140 is seated and supported by the locking jaw 123 of the guide pipe connector 120 and the locking jaw 134 of the close support 130, respectively, the bottom of the housing 131 The engaging projection 138 is formed in the induction pipe 140 so that the induction pipe 140 of the intake pipe 110 is prevented from being pushed into the housing 131 when the induction pipe 140 is mounted. It is to prevent the departure from the inside to the bottom.

탈착의 과정은, 유도관(140)이 상측으로 이동되면, 유도관(140)의 후단 상측이 회동편(133)의 상측을 뒤고 밀게되고, 이로 인해 회동편(133)의 하측이 회동하여 유도관(140)의 후단 하측을 상부로 밀게 된다.Desorption process, when the induction pipe 140 is moved to the upper side, the rear end upper side of the induction pipe 140 is pushed behind the upper side of the rotating piece 133, and thus the lower side of the rotating piece 133 is rotated to induce The rear end of the tube 140 is pushed upward.

그러므로, 쉽게 유도관(140)이 회동편(133)으로부터 이탈되어 분리가 가능하게 되는 것이다.Therefore, the guide tube 140 is easily separated from the rotating piece 133 to be separated.

그런데, 이와같은 종래의 기술은 펌핑의 종료시 유도관(240)의 입수구(241)로부터 물의 압력이 발생하지 않기 때문에 관정의 위치보다 높게 설치된 물탱크로부터 배수구(242)를 통해 물이 역류하게 되며, 이때 역류되는 물이 입수구(241)로 유입되는 것을 방지할 마땅한 방안이 없어 역류되는 물에 의하여 지하수의 오염이 발생하는 경우가 발생한다.
However, in the conventional technique, since water pressure does not occur from the inlet 241 of the induction pipe 240 at the end of the pumping, water flows back through the drain 242 from the water tank installed higher than the position of the well, At this time, since there is no proper way to prevent the water flowing back into the inlet 241, contamination of groundwater occurs due to the water flowing back.

본 발명은 이러한 종래의 문제점을 해결하고자, 유도관에 물의 압력에 의하여 승하강하는 체크밸브를 설치하여 물의 역류시에 유도관이 닫히도록 함으로써 지하수의 오염을 방지하도록 하는 체크밸브를 갖는 지하수공의 오염방지장치를 제공하는데 그 목적이 있다.
The present invention is to solve the conventional problems, by installing a check valve to increase and decrease by the pressure of the water in the induction pipe to ensure that the induction pipe is closed in the case of water backflow by having a check valve to prevent contamination of groundwater The purpose is to provide a pollution prevention device.

지하수공에 취수관이 삽입되어 취수관 내부에서 펌프에 의해 펌핑된 지하수를 취수관의 측면으로 배출하도록 구성된 지하수공의 오염방지장치에 있어서,In the water pipe is inserted into the ground water hole in the ground water hole pollution prevention device configured to discharge the ground water pumped by the pump in the intake pipe to the side of the intake pipe,

상기 취수관의 내측에 삽입되어 펌프로부터 펌핑되어진 지하수를 취수관의 측면쪽으로 유도하기 위하여 하부로는 지하수를 유입받는 입수구가 형성되고, 상기 입수구와 연통되면서 측면으로 배수구가 형성된 유도관;An induction pipe formed at a lower part of the inlet to receive ground water to guide the groundwater inserted into the intake pipe and pumped from the pump toward the side of the intake pipe, and having a drain hole formed at a side thereof while communicating with the inlet;

입수구를 통해 입수되는 지하수의 압력에 의해 상승하여 입수구를 개방시키고, 배수구를 통해 역류되는 물의 무게에 의해 입수구를 폐쇄시키는 체크밸브;로 구성된다.
It consists of a check valve that rises by the pressure of the ground water received through the inlet to open the inlet, and closes the inlet by the weight of the water flowing back through the drain.

이러한 본 발명에 의하여 역류되는 물이 지하수공으로 다시 역류되어 유입되지 않도록 함으로써 역류되는 물에 의한 지하수의 오염을 방지하는 효과를 갖는다.
The water flowing back by the present invention is prevented from flowing back into the ground water hole to prevent the contamination of the ground water by the water flowing back.

본 발명의 구성 및 동작상태를 도3을 참조하여 상세히 설명한다.The configuration and operation of the present invention will be described in detail with reference to FIG.

기본적인 구조는 도1 및 도2에서 도시된 종래의 구성과 동일하므로 본 발명의 추가 구성을 나타내는 유도관(240)과 체크밸브(250)의 구성에 대하여 중점적으로 설명하며, 유도관(240)이 취수관(210)의 내측에 삽입되어 장착된 상태로서 체크밸브(250)의 구조와 동작관계를 설명한다.Since the basic structure is the same as the conventional configuration shown in Figs. 1 and 2, the configuration of the induction pipe 240 and the check valve 250 showing the additional configuration of the present invention will be mainly described, and the induction pipe 240 is The structure and operation relationship of the check valve 250 as a state inserted into the intake pipe 210 is mounted.

유도관(240)은 펌프로부터 펌핑된 지하수를 유입받기 위한 입수구(241)가 형성되어 있으며, 측면으로는 배수구(242)가 형성되어 있어서 펌핑된 지하수를 90도 방향으로 유도시켜 토출구(221)를 통하여 배출되도록 한다.Induction pipe 240 is formed with an inlet 241 for receiving the pumped ground water from the pump, the drain hole 242 is formed on the side to guide the pumped ground water in the 90 degree direction discharge port 221 To be discharged.

또한, 유도관(240)의 상측으로는 길다란 관 형태의 상부연장관(244)이 인입되어 유도관(240)의 내측과 서로 연결되면서 입수구(241)와 직선으로 연통되는 위치에 장착된다.In addition, the upper extension pipe 244 of the long pipe shape is introduced into the upper side of the induction pipe 240 is connected to the inside of the induction pipe 240 and is mounted in a position that is in straight communication with the inlet 241.

상기 상부연장관(244)의 하부 내측으로는 체크밸브(250)가 삽입되어 설치되는데, 상기 체크밸브(250)는 상부가 개방된 통체로 되어 내측으로는 공간부(251)가 형성되면서 그 외벽이 상부연장관(244)의 내벽에 근접하거나 또는 상하방향으로 슬라이딩이 가능한 정도로 맞닿아 있게 된다.The check valve 250 is inserted and installed in the lower inner side of the upper extension pipe 244. The check valve 250 is a cylindrical body having an open upper portion. The inner wall of the upper extension pipe 244 is in close contact with or to the extent possible to slide in the vertical direction.

또한, 측벽에는 유입공(252)이 형성되어 내부의 공간부(251)와 외측을 서로 연통되도록 하며, 하측은 하부방향으로 원뿔형태를 가지는 막음부(253)가 형성되어 있으면서 그 막음부(253)의 가장자리 둘레로는 외측으로 돌출된 돌출턱(254)이 형성되어 있다.In addition, the inlet hole 252 is formed in the side wall so that the internal space portion 251 and the outside communicate with each other, and the lower portion has a concave portion 253 having a conical shape in the lower direction while the blocking portion 253 is formed. Protruding jaw 254 protruding outward is formed around the edge of the edge.

유도관(240)의 입수구(241)의 내측 둘레로는 내측방향으로 돌출된 환형 돌출부(243)가 형성되어 있어서, 상기 체크밸브(250)가 유도관의 외측으로 이탈되는 것을 방지함과 동시에 막음부(253)가 환형돌출부(243)의 상단에 걸리는 경우 입수구(241)가 폐쇄되도록 한다.An inner periphery of the inlet 241 of the inlet pipe 240 is formed with an annular protrusion 243 protruding inwardly, preventing the check valve 250 from escaping to the outside of the induction pipe at the same time. When the portion 253 is caught on the upper end of the annular projection 243, the inlet 241 is closed.

아울러 상부연장관(244)의 하측에는 내측 둘레로 별도의 걸림턱(245)이 형성되어 있어서, 체크밸브(250)가 걸림턱(245)과 환형돌출부(243)의 사이에서 상하왕복운동하도록 제한하며, 굳이 걸림턱(245)을 형성하지 않는 경우 유도관(240)의 내측으로 인입된 상부연장관(244)의 두께가 그 걸림턱(245)을 대신 할 수 있을 것이다.
In addition, the lower side of the upper extension tube 244 is formed with a separate locking jaw 245 around the inner circumference, so that the check valve 250 restricts the up and down reciprocating motion between the locking jaw 245 and the annular projection 243. If the dare 245 is not formed, the thickness of the upper extension pipe 244 drawn into the induction pipe 240 may be substituted for the jaw 245.

이러한 본 발명의 동작을 설명한다.The operation of the present invention will be described.

도3(a)는 펌프가 동작하여 지하수를 펌핑하는 경우의 체크밸브(250) 위치를 보인 도로서, 입수구(241)을 통해 펌핑된 지하수의 압력에 의해 체크밸브(250)가 상승하여 돌출턱(254)에 걸린상태이며, 이때, 입수구(241)와 배수구(242)는 서로 개방되어 펌핑된 지하수가 토출구(221)를 통해 외부로 배출됨으로써 별도의 탱크에 저장된다.Figure 3 (a) is a diagram showing the position of the check valve 250 in the case of pumping the ground water by operating the pump, the check valve 250 is raised by the pressure of the ground water pumped through the inlet 241 protruding jaw 254, the water inlet 241 and the drain 242 is open to each other and the pumped ground water is discharged to the outside through the discharge port 221 is stored in a separate tank.

도3(b)는 펌핑이 종료되어 입수구(241)를 통해 지하수가 유입되지 않는 경우 체크밸브(250)의 자중에 의해 하강하는 과정을 보인 도이며, 이때 배수구(242)를 통해 역류되어 유입되는 물이 유입공(252)을 통해 공간부(251)의 내측으로 유입된다.Figure 3 (b) is a diagram showing the process of descending by the weight of the check valve 250 when the grounding is not flowing through the inlet 241 after the pumping is completed, in this case flowed back through the drain 242 Water is introduced into the space portion 251 through the inlet hole 252.

이렇게 유입된 물과 체크밸브(250)의 자중에 의해 체크밸브(250)는 계속하강하여 그 하측단부의 막음부(253)가 환형돌출부(243)에 걸림으로써 입수구(241)를 폐쇄시키며, 아울러 상부연장관(244)의 내측으로도 물이 계속 차올라 그 무게에 의해 체크밸브(250)가 입수구(241)를 기밀하게 폐쇄한다.The check valve 250 continues to descend due to the water introduced in this way and the weight of the check valve 250 to close the inlet 241 by the blocking portion 253 of the lower end thereof being caught by the annular projection 243. The water continues to rise even inside the upper extension pipe 244, and the check valve 250 closes the water inlet 241 hermetically by the weight thereof.

그러므로, 배수구(242)를 통해 역류되는 물은 더이상 입수구(241)로 유입되지 않아 지하수의 오염이 방지된다.Therefore, the water flowing back through the drain 242 is no longer introduced into the inlet 241 to prevent contamination of the groundwater.

지하수를 다시 펌핑하는 경우 입수구(241)를 통해 펌핑된 지하수의 압력에 의해 다시 체크밸브(250)는 상승하게 되어 입수구(241)를 개방하며, 이후 펌핑 종료시에는 상부연장관(244)의 내부에 물이 차있는 상태이므로 체크밸브(250)의 자중과 물의 무게에 의해 더 빨리 입수구(241)를 폐쇄하게 된다.
In the case of pumping the ground water again, the check valve 250 is raised again by the pressure of the ground water pumped through the inlet 241 to open the inlet 241, and when the pumping ends, the water inside the upper extension pipe 244.
