본 발명은 저수조 수위조절방법에 관한 것으로, 더욱 상세하게는 저수조에 연결되어 있는 급수배관의 압력을 이용하여 저수조의 수위를 측정하고 일정수위가 되면 펌프를 이용하여 물을 펌핑하여 급수배관을 통하여 저수조에 급수한다. 저수조에 공급되는 급수량은 수량계로 측정하여 일정한 수량이 저수조에 공급되도록 함으로써 저수조의 수위를 조정하는 저수조 수위조절방법이다.The present invention relates to a reservoir level control method, and more particularly, to measure the water level of the reservoir using the pressure of the water supply pipe connected to the reservoir, and when the water level reaches a certain level, the water is pumped using a pump to store the reservoir through the water supply pipe. Water on. The amount of water supplied to the reservoir is measured by a water meter so that a certain amount of water is supplied to the reservoir, thereby adjusting the water level of the reservoir.

기존의 저수조 수위조절장치는 무선 주파수방식, 유선방식 등이 사용되고 있다.Conventional water tank level control device has been used, such as radio frequency method, wired method.

무선 주파수방식은 저수조내에 설치된 수위감지센서에 의해 수위를 감지하여 무선송신기로 송신하여 무선수신기로 수신하여 모터펌프를 구동하여 저수조에 급수하는 방식이다. 이 방식은 배관에 압을 가하지 않으며, 무선방식으로 제어가 가능하고, 기존시설에 설치가 용이한 장점이 있으나, 많은 전파사용으로 잦은 에러가 발생하고 먼 거리에서 오작동이 많이 발생한다. 또한 낙뢰에 의한 피해가 심하다.The radio frequency method detects the water level by the water level sensor installed in the water tank, transmits it to the radio transmitter, receives the radio receiver, and drives the motor pump to feed the water tank. This method does not apply pressure to the pipe, it can be controlled wirelessly, and it is easy to install in an existing facility. However, due to the use of a lot of radio waves, frequent errors occur and many malfunctions occur at a long distance. In addition, the damage from lightning is severe.

유선방식은 저수조내에 설치된 수위감지센서에 의해 수위를 감지하여 유선으로 제어기에 전달하여 모터펌프를 구동하는 방식으로, 단거리에서는 저렴한 가격으로 설치할 수 있는 장점이 있다. 그러나 취수정과 저수조의 거리가 300M 이상일 때에는 설치비용이 많이 들며, 낙뢰의 피해 및 단선 등으로 인한 고장 발생 및 감전사고 등이 발생할 수 있다.The wired method detects the water level by the water level sensor installed in the water tank and transfers it to the controller by wire to drive the motor pump, which can be installed at a low price in a short distance. However, when the distance between the intake well and the reservoir is more than 300M, the installation cost is high, and failure and electric shock may occur due to lightning damage and disconnection.

따라서 본 발명은 상기와 같은 문제점을 해결하고자 안출된 것으로, 급수배관의 배관압을 측정하여 저수조의 수위를 측정하고 급수배관에 급수되는 급수량을 수량계로 측정하여 저수조에 공급되는 수량을 조정하여 저수조의 수위를 조절하는 것으로 오작동 및 낙뢰의 피해를 줄이고 안정적인 저수조의 수위를 조절하는 것이다.Therefore, the present invention has been made to solve the above problems, by measuring the pipe pressure of the water supply pipe to measure the water level of the reservoir and to measure the amount of water supplied to the water supply pipe with a water meter to adjust the amount of water supplied to the reservoir By adjusting the water level, it is possible to reduce the damage of malfunctions and lightning strikes and to control the water level of the stable reservoir.

본 발명은 저수조의 수위조절장치로서 도 1 과 같이 취수정에 설치된 펌프(2)로 펌핑을 하여 급수배관(4)을 통하여 저수조(1)에 급수하는 것이다.The present invention is to supply water to the reservoir (1) through the water supply pipe (4) by pumping the pump (2) installed in the intake well as a water level control device of the reservoir.

상기 급수배관(4)의 구성은 배관의 기포를 제거하기 위한 공기변(11)과 배관의 압력을 측정하는 압력게이지(12)와 배관압을 측정하여 제어기(3)에 전달하는 압력센서(15)와 급수량을 측정하는 수량계(13)와 급수량을 조절하기 위한 수량센서(16)와 리프트 체크밸브(14)와 잠금밸브(17) 및 볼탑(5)으로 구성되어 있다.The water supply pipe 4 is composed of an air valve 11 for removing air bubbles in the pipe, a pressure gauge 12 for measuring the pressure of the pipe, and a pressure sensor 15 for measuring the pipe pressure and delivering the pressure to the controller 3. ) And a water meter 13 for measuring the water supply amount, a water level sensor 16 for adjusting the water supply amount, a lift check valve 14, a lock valve 17, and a ball top 5.

상기 제어기(3)는 압력센서(15)와 수량센서(16)로부터 신호를 받아 펌프(2)를 ON/OFF 시킨다.The controller 3 receives signals from the pressure sensor 15 and the water quantity sensor 16 to turn the pump 2 ON / OFF.

저수조(1)에 상측에 급수를 위한 볼탑(5)이 설치된 급수배관(4)과, 하측으로는 청소를 하기 위한 드레인관이 설치되어 있으며, 저수소(1)의 수위 변화에 따른 압력변화를 급수배관(4)에 전달되도록 연결배관(6)을 급수배관(4)과 연결되도록 설치한다.A water supply pipe 4 having a ball top 5 for water supply in the reservoir 1 and a drain pipe for cleaning in the lower part of the water tank 1 is installed, and a pressure change according to the water level change of the water reservoir 1 is performed. The connection pipe 6 is installed to be connected to the water supply pipe 4 so as to be delivered to the water supply pipe 4.

상기 연결배관(6)의 크기는 보통 10mm관을 사용하며 저구조의 하측에 설치된 다.The size of the connecting pipe (6) is usually used 10mm pipe is installed on the lower side of the low structure.

상기와 같이 구성되는 본 발명의 수위조절방법을 상세히 설명하면 다음과 같다.Referring to the water level adjusting method of the present invention configured as described above in detail.

저수조(1)이 급수된 물이 저수위(H1), 안정값 수위(H2), 고수위(H3) 일때의 급수배관(4)에 걸리는 배관압력을 압력게이지(12)를 이용하여 각각 측정하여 제어기(3)에 입력시킨다.When the water supplied to the reservoir 1 is at the low water level (H1), the stable water level (H2), and the high water level (H3), the pipe pressure applied to the water supply pipe 4 is measured using the pressure gauge 12, respectively. Enter 3).

상기 저수위(H1), 안정값 수위(H2), 고수위(H3)의 수위는 저수조(1)의 크기에 따라 위치가 변화될 수 있으며, 또한, 저수위(H1), 안정값 수위(H2), 고수위(H3) 일 때에 급수배관(4)에 작용하는 배관압력은 저수조(1)의 위치 및 크기에 따라 변화한다.The water level of the low water level (H1), the stable value water level (H2), the high water level (H3) can be changed in position according to the size of the water reservoir (1), and also, the low water level (H1), stable value water level (H2), high water level In the case of (H3), the pipe pressure acting on the water supply pipe 4 changes depending on the position and size of the reservoir 1.

즉, 저수조(1)와 압력게이지(12)의 위치(높이) 차가 많이날수록 급수배관(4)에 작용하는 압력을 증가한다.That is, as the position (height) difference between the reservoir 1 and the pressure gauge 12 increases, the pressure acting on the water supply pipe 4 increases.

수위와 압력의 관계는 물의 높이가 10m일때 약 1기압이다.The relationship between the water level and the pressure is about 1 atmosphere when the water height is 10m.

저수조(1)의 하측에 설치되어 급수배관(4)과 연결된 연결배관(6)을 통하여 수위변동에 따른 압력의 변화로 저수조(1)의 수위를 확인할 수 있다.The water level of the reservoir 1 can be confirmed by the change of the pressure according to the water level change through the connection pipe 6 installed at the lower side of the reservoir 1 and connected to the water supply pipe 4.

저수조(1)의 수위가 안정값 수위(H2)가 되면 펌프를 가동시켜 고수위(H3)가 될때까지 급수를 하며, 안정값 수위(H2)부터 고수위(H3)까지 공급되는 급수량을 수량계(13)를 이용하여 측정을 하여 제어기(3)에 입력시킨다.When the water level of the reservoir 1 reaches the stable value level (H2), the pump is operated to supply water until it reaches a high level (H3), and the water supply amount supplied from the stable value level (H2) to the high level (H3) is measured by the water meter (13). Measured by using and input to the controller (3).

여기서 급수량을 저수조(1)의 고수위(H3)에서 안정값 수위(H2)까지의 저수조(1)의 용적을 계산하여 구할 수 있으나, 직접 급수를 10회 정도 하여 공급되는 수 량의 평균값으로 급수량을 정하는 것이 좋다.Here, the water supply can be obtained by calculating the volume of the water storage tank 1 from the high water level H3 of the water storage tank 1 to the stable value water level H2. It is good to decide.

저수조(1)의 수위가 고수위(H3)에서 안정값 수위(H2)에 이르면 급수배관(4)에 걸리는 압력이 압력게이지(12)에 측정되어, 압력센서(15)를 통하여 제어기(3)에 신호를 보내면, 상기 제어기(3)에서는 압력센서(15)의 보내지는 신호에 의하여 저수조(1)의 수위를 확인할 수 있으며, 안정값 수위(H2)일때의 신호를 받아 펌프를 구동시켜 저수조(1)에 급수배관(4)을 통하여 급수를 시작한다.When the water level of the reservoir 1 reaches the stable value level H2 from the high water level H3, the pressure applied to the water supply pipe 4 is measured by the pressure gauge 12, and the pressure sensor 15 is applied to the controller 3 through the pressure sensor 15. When the signal is sent, the controller 3 can check the water level of the reservoir 1 by the signal sent from the pressure sensor 15, and receives the signal at the stable value level H2 to drive the pump to hold the reservoir 1 Start water supply through the water supply pipe (4).

상기 급수배관(4)을 통하여 급수되는 량은 수량계(13)를 통하여 측정되며, 일정한 급수량(안정값 수위(H2)에서 고수위(H3)까지의 수량)의 급수가 되어지면 수량센서(16)에서 제어기(3)에 신호를 보낸다.The amount of water supplied through the water supply pipe 4 is measured by the water meter 13, and when the water supply of a constant amount of water (the amount from the stable level H2 to the high level H3) is supplied, the water level sensor 16 Send a signal to the controller (3).

상기 제어기(3)는 수량센서(16)의 신호를 받아 펌프(2)를 정지시켜 급수를 중단시킴으로써 저수조(1)의 수위를 조정하는 것이다.The controller 3 adjusts the water level of the reservoir 1 by stopping the water supply by stopping the pump 2 in response to the signal of the water quantity sensor 16.

또한 제어기(3)에 타이머를 설치하여 일정한 시간 간격(약 60 ~ 120분)으로 소량(약 50 ~ 100ℓ)의 물을 급수함으로써 동절기에 동파로 인한 피해를 줄일 수 있는 것이다.In addition, by installing a timer in the controller (3) by watering a small amount (about 50 ~ 100l) at regular time intervals (about 60 ~ 120 minutes) to reduce the damage caused by freezing in winter.

도 3 과 같이 기존의 급수배관(4)에 압력센서(15)와, 수량계(13) 및 수량센서(16)를 설치하고, 양센서를 제어기(3)와 연결하여 사용할 수 있는 것이다.As shown in FIG. 3, a pressure sensor 15, a water meter 13, and a water sensor 16 are installed in the existing water supply pipe 4, and both sensors may be connected to the controller 3.

본 발명은 압력을 이용하여 저수조의 수위를 측정하여 급수하며, 수량계를 이용한 일정한 량의 수량을 공급함으로써 저수조에서 급수된 물이 넘치는 것을 방지할 수 있음으로써 보다 안정적으로 저수조의 수위조절을 할 수 있다. 또한 동절 기에도 일정한 시간간격으로 일정한 수량을 공급함으로써 동파를 예방할 수 있다.The present invention can measure the water level of the water tank using pressure, and by supplying a certain amount of water using a water meter to prevent the water supplied from the water tank overflowing, it is possible to more stably control the water level of the water tank. . In addition, winter can be prevented by supplying a certain quantity at regular time intervals in winter.
