이와 같이 구성된 본 발명은 첨부한 도면을 참조하여 상세히 설명한다.The present invention thus constructed will be described in detail with reference to the accompanying drawings.

도2는 본 발명에서 적용된 송수 가압부(100)의 구조를 보인 도로서, 송수 가압부(100)는 지하로부터 취수된 지하수가 저장된 지하수 저장탱크의 근처에 위치하여 지하수 저장탱크로부터 지하수를 공급받아 가압하는 것이다.FIG. 2 is a view showing the structure of the water supply and pressurization unit 100 applied in the present invention. The water supply and pressurization unit 100 is located near a ground water storage tank storing ground water taken from the ground, Pressure.

이를 위해 지중에 매설된 원통형의 몸체(110)의 측부에 지하수 저장탱크로부터 유출된 지하수를 유입받는 입수관(120)이 설치되며, 입수관(120)을 통해 유입된 지하수는 몸체(110)의 내부에 저장된다.For this purpose, a water inlet pipe 120 is installed at a side of a cylindrical body 110 embedded in the ground, and groundwater flowing out from the ground water storage tank is introduced into the water inlet pipe 120, Lt; / RTI >

몸체(110)의 내부에는 상하방향으로 직립되도록 취수관(130)이 설치되는데, 취수관(130)에는 저장된 물이 내부로 유입되도록 다수의 취수구멍(131)이 형성되며, 내부에는 가압펌프(140)가 설치된다.A plurality of water intake holes 131 are formed in the water intake pipe 130 so that stored water flows into the interior of the body 110. A pressurizing pump 140 are installed.

따라서, 취수관(130)의 내부로 유입된 지하수는 가압펌프(140)에 의해 가압되어 취수관(130)의 내부에 설치된 양수관(150)을 통해 유도관(160)으로 유입되며, 유도관(160)으로부터 배출되는 지하수는 출수관(170)을 통해 몸체(110)의 외부로 유출되고, 출수관(170)은 지중에 매설된 송수관로와 접속되어 가압된 지하수를 배출하게 된다.The groundwater introduced into the water intake pipe 130 is pressurized by the pressurizing pump 140 and flows into the induction pipe 160 through the water pipe 150 installed inside the water intake pipe 130, The groundwater discharged from the water pipe 160 flows out to the outside of the body 110 through the water pipe 170 and the water pipe 170 is connected to the water pipe embedded in the ground to discharge the pressurized ground water.

이때, 출수관(170)은 취수관(130)에 접속되어 고정된 구조를 가지며, 가압펌프(140)의 유지보수를 위하여 유도관(160)의 하측에서 양수관(150)이 고정 접속되고, 양수관(150)의 하측에는 가압펌프(140)가 고정설치되는 구조를 갖는다.The water pipe 170 is connected to and fixed to the water intake pipe 130. The water pipe 150 is fixedly connected to the lower side of the induction pipe 160 for maintenance of the pressure pump 140, And a pressure pump 140 is fixedly installed on the lower side of the water pipe 150.

상기 유도관(160)의 구조는 본 출원인이 이미 등록한 등록특허 제10-0890815호의 '지하수의 오염방지장치'의 구조와 동일하므로 구체적인 구조에 대해서는 설명하지 않는다.The structure of the induction pipe 160 is the same as that of the 'Groundwater contamination prevention device' of the registered patent application No. 10-0890815 already registered by the applicant of the present invention, so the detailed structure is not described.

그러므로, 취수관(130)의 상부캡(132)의 연 다음 유도관(160)을 위로 잡아 올리게 되면, 유도관(160)이 출수관(170)과 분리되면서, 양수관(150)과 가압펌프(140)가 같이 상측으로 들어 올려져 취수관(130)으로 부터 이탈되는 것이다.Therefore, when the induction pipe 160 is lifted up after the upper cap 132 of the intake pipe 130 is opened, the induction pipe 160 is separated from the water pipe 170, and the water pipe 150, (140) are lifted up to the upper side and separated from the water intake pipe (130).

이러한 가압펌프(140)는 몸체(110)의 상측에 위치한 동력판넬(111)로부터 동력을 인가받아 동작하게 된다.The pressurizing pump 140 is operated by receiving power from the power panel 111 located on the upper side of the body 110.

한편, 지하수 저장탱크에 저장된 지하수에는 모래 등의 슬러그(S)가 포함되어 있으므로, 이를 제거하여 깨끗한 지하수를 공급하여야 하는데, 이를 위해 몸체(110)의 내측 하부에는 바닥과 공간을 두고 도3에서와 같은 슬러그 필터(190)가 설치된다.Since the groundwater stored in the groundwater storage tank contains slug S such as sand, it is necessary to remove the slug S and supply clean groundwater. To this end, a ground and a space are provided in the inner lower portion of the body 110, The same slug filter 190 is installed.

슬러그 필터(190)는 원판 형태로 되어 몸체(110)의 내부를 가로질러 장착되며, 슬러그(S)를 필터링할 수 있도록 다수의 타공(181)이 형성되어 있다.The slug filter 190 has a disk shape and is mounted across the inside of the body 110 and has a plurality of perforations 181 for filtering the slug S therein.

또한, 취수관(130)과 입수관(120)을 하측으로 관통시키기 위한 취수관 삽입공(182)과 입수관 삽입공(183)이 형성되어 있다.A water intake tube insertion hole 182 and a water intake tube insertion hole 183 for allowing the water intake tube 130 and the water intake tube 120 to pass downward are formed.

따라서, 입수관(120)을 통해 입수된 지하수는 슬러그 필터(190)의 하측으로 유입되어 타공(181)에 의해 슬러그(S)가 제거된 지하수가 상측으로 유출되며, 타공(181)에 의해 지하수에 포함된 슬러그(S)가 필터링되어 몸체(110)의 바닥에 쌓이게 된다.The groundwater obtained through the water inlet pipe 120 flows into the lower side of the slug filter 190 and the groundwater having the slag S removed by the perforation 181 flows upward, The slug S included in the slug S is filtered and accumulated on the bottom of the body 110.

취수관(130)의 취수구멍(131)은 슬러그 필터(190)의 상측에 형성됨이 바람직하고, 바닥에 쌓인 슬러그(S)를 제거하기 위하여 몸체(110)의 상측으로부터 슬러그 청소용 파이프(180)가 삽입되고, 그 하단이 플러그 필터(190)의 파이프 삽입공(184)을 통해 관통되어 위치한다.The intake hole 131 of the intake pipe 130 is preferably formed on the upper side of the slug filter 190 and the slug cleaning pipe 180 is installed from the upper side of the body 110 to remove the slug S accumulated on the floor And the lower end thereof penetrates through the pipe insertion hole 184 of the plug filter 190 and is positioned.

따라서, 슬러그 청소용 파이프(180)를 통해 슬러그를 흡입시켜 외부로 배출시켜 청소가 용이하도록 한다.Therefore, the slug is sucked through the slug cleaning pipe 180 and discharged to the outside, thereby facilitating the cleaning.

아울러, 평상시에는 슬러그 청소용 파이프(180)의 내측에 수위센서를 장착하여 수위가 형성된 경우에만 동력판넬(111)의 제어에 의해 가압펌프(140)가 동작되도록 한다.The pressure pump 140 is operated under the control of the power panel 111 only when the water level sensor is installed inside the slug cleaning pipe 180 at a normal time and the water level is formed.

도4는 송수관로상에 일정 거리마다 설치된 중간 가압부(200)의 구조를 보인 도로서, 송수 가압부(100)를 통해 가압된 지하수가 지중에 매설된 송수관로를 통해 유입되면, 가압력이 많이 약해진 상태이므로 다시 지하수를 가압하여 송수관로를 통해 송수하게 된다.4 is a view showing the structure of the intermediate pressurizing unit 200 installed at a certain distance on the water line, and when the ground water pressurized through the water supply pressurizing unit 100 flows through the water line embedded in the ground, Therefore, the groundwater is pressurized again and sent through the water line.

이를 위해 지중에 매설된 원통형의 몸체(210)의 측부에 지하수 저장탱크로부터 유출된 지하수를 유입받는 입수구(220)가 설치되며, 입수구(220)을 통해 유입된 지하수는 몸체(210)의 내부에 저장된다.For this purpose, an inlet port 220 for receiving the groundwater discharged from the groundwater storage tank is installed at the side of the cylindrical body 210 embedded in the ground, and the groundwater introduced through the inlet port 220 is connected to the inside of the body 210 .

몸체(210)의 내부에는 상하방향으로 직립되도록 취수관(230)이 설치되는데, 취수관(230)에는 저장된 물이 내부로 유입되도록 취수구멍이 형성되며, 내부에는 가압펌프(240)가 설치된다.A water intake pipe 230 is installed inside the body 210 so as to be vertically upright. A water intake hole is formed in the water intake pipe 230 so that the stored water flows into the interior of the body 210, and a pressurization pump 240 is installed inside the water intake pipe 230 .

따라서, 취수관(230)의 내부로 유입된 지하수는 가압펌프(240)에 의해 가압되어 출수관(250)을 통해 몸체(210)의 외부로 유출되고, 출수관(250)은 지중에 매설된 송수관로와 접속되어 가압된 지하수를 배출하게 된다.Therefore, the groundwater introduced into the water intake pipe 230 is pressurized by the pressurization pump 240 and flows out to the outside of the body 210 through the water outlet pipe 250, and the water outlet pipe 250 is embedded in the ground And connected to the water line to discharge the pressurized groundwater.

이러한 가압펌프(240)는 몸체(210)의 상측에 위치한 동력판넬(260)로부터 동력을 인가받아 동작하게 되며, 동력판넬(260)과의 전기적 접속을 위해 동력판넬(260)로부터 몸체(210) 사이에 케이블 파이프(270)가 설치되어 케이블 파이프(270)의 내부로 케이블이 인입되어 가압펌프(240)와 전기적으로 연결되는 것이다.The pressurizing pump 240 is operated by receiving power from the power panel 260 located on the upper side of the body 210 and is operated from the power panel 260 to the body 210 for electrical connection with the power panel 260. [ A cable is inserted into the cable pipe 270 and is electrically connected to the pressurizing pump 240. [

따라서, 송수관로의 중간중간에서 중간 가압부(200)에 의해 가압된 지하수가 원격지의 마을까지 압력이 유지된 상태로 송수될 수 있는 것이다.
Accordingly, the groundwater pressurized by the intermediate pressurizing unit 200 in the middle of the water pipe can be transmitted and received while maintaining the pressure to the remote village.
