본 발명은 빗물의 산성도를 측정하는 장치에 관한 것으로, 좀 더 상세하게는 산성비를 분취하여 산도를 측정하는 산성비의 산성도 측정기에 관한 것이다.The present invention relates to a device for measuring the acidity of rainwater, and more particularly to an acidity meter of acid rain to measure the acidity by fractionating the acid rain.

산성비는 대기중에 함유되어 있는 산성가스 물질 등이 빗물에 씻겨 낙하되어 산성도를 갖는 빗물로 되는 것으로, 이러한 산성비가 지면으로 낙하할 때 이를 채취하여 빗물의 산도를 측정함으로써 각 지역의 오염정도를 파악하여 대기환경 및 기상관련 연구에 활용하고 있다.Acid rain is the rain water having acidity after being washed down by rain gas acid substances in the air, and when the acid rain falls to the ground, it collects it and measures the acidity of rain water to determine the pollution level in each area. It is used for atmospheric environment and meteorological research.

종래 사용되고 있는 산성비 자동측정기는 빗물의 산도를 계속적으로 자동 측정하지만, 비가 내리는 정도에 관계없이 1리터 정도의 용기에 채워진 빗물을 일정한 간격으로 산도 측정하는 전취 방식을 취하고 있다.The acid rain automatic measuring device used in the prior art continuously measures the acidity of rainwater, but takes the method of acrobatic measurement of acidity at regular intervals of rainwater filled in a container about 1 liter irrespective of the degree of rain.

따라서, 항상 용기에 채워진 평균치로만 측정이 이루어져서 비의 양에 대한 정확한 산도 측정이 이루어지지 못하는 문제점이 있다.Therefore, there is a problem that the measurement is always made only with the average value filled in the container, so that the accurate acidity measurement for the amount of rain cannot be made.

또한 산도의 측정이 완료된 후 pH 전극에 대한 세척, 보관이 제대로 이루어지지 못하여 정확한 데이터를 얻을 수 없게 된다.In addition, after the pH measurement is completed, the pH electrode cannot be washed and stored properly, and thus accurate data cannot be obtained.

한편 데이터 로거를 설치하여 시간에 따른 pH 농도데이터를 지속적으로 보관하고 있기 때문에, 데이터 수거를 위해 PC 등의 또 다른 장비를 이용하여야 하며, 측정장비가 있는 곳까지 이동하는 불편함이 따른다.On the other hand, since the data logger is installed to keep the pH concentration data over time, it is necessary to use another equipment, such as a PC for data collection, it is inconvenient to move to the measuring equipment.

본 발명은 상술한 문제점을 해결하기 위해 안출된 것으로, 그 목적은 일정 강수량마다 분취하여 빗물의 정확한 산성도를 측정하는 산성비의 산성도 측정기를 제공하는 데 있다.The present invention has been made to solve the above-described problems, an object of the present invention is to provide an acidity meter of acid rain to measure the correct acidity of rain water by fractional precipitation every predetermined rainfall.

또한, 증류수를 이용하여 pH 전극을 자동으로 세척하고, KCl 용액을 자동으로 공급하여 pH 전극을 보관하여 pH 전극에 의한 측정 오차 범위를 최소화할 수 있는 산성비의 산성도 측정기를 제공하는 데 있다.In addition, the pH electrode is automatically washed with distilled water, and the KCl solution is automatically supplied to store the pH electrode to provide an acidity meter of the acid rain to minimize the measurement error range by the pH electrode.

아울러, 측정된 데이터는 즉시 LAN을 통해 송신하여 작업자가 장비가 있는 곳까지 이동하지 않고서도 사무실 등에서 실시간으로 데이터를 수신할 수 있는 산성비의 산성도 측정기를 제공하는 데 있다.In addition, the measured data is immediately transmitted over the LAN to provide an acid rain acidity meter that can receive data in real time in the office, etc. without having to move to the place where the equipment is located.

도 1은 본 발명에 따른 산성비 산성도 측정기를 도시한 개략도.1 is a schematic view showing an acid rain acidity meter according to the present invention.

상술한 바와 같은 목적을 달성하기 위한 본 발명의 장치는, 빗물을 받는 채취 깔대기; 이 채취 깔대기의 하부에 설치되어 빗물이 채워지고, 내부에 상기 빗물의 수위를 감지하는 레벨센서와 빗물의 산성도를 측정하는 pH전극이 설치되며, 하부에는 빗물의 흐름을 제어하는 제1밸브가 설치된 측정 셀; 및 레벨센서, pH전극, 제1밸브와 접속되어 측정 셀에 채워진 빗물의 수위에 따라 제1밸브의 개폐를 선택적으로 제어하고, pH전극에서 측정된 데이터를 PC로 전송하는 콘트롤 패널을 포함하여 이루어진다.The apparatus of the present invention for achieving the above object, the collecting funnel receiving rain water; Rainwater is filled in the lower part of the harvesting funnel, and a level sensor for detecting the water level of the rainwater and a pH electrode for measuring the acidity of the rainwater are installed therein, and a first valve for controlling the flow of rainwater is installed in the lower part. Measuring cell; And a control panel connected to the level sensor, the pH electrode, and the first valve to selectively control the opening and closing of the first valve according to the level of the rainwater filled in the measurement cell, and transmitting the data measured at the pH electrode to the PC. .

이하 첨부된 도면에 의거하여 본 발명에 따른 바람직한 실시예를 상세히 설명한다. 도 1은 본 발명에 따른 산성비 산성도 측정기를 도시한 개략도이다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a schematic diagram showing an acid rain acidity meter according to the present invention.

측정기는 상부에 빗물을 받을 수 있는 채취 깔대기(1)가 설치되고, 채취 깔대기(1)는 상부에 덮개(2)가 설치되며, 이 덮개(2)는 채취 깔대기(1)의 측방에 설치된 회전모터(4)에 의해 회동되어 채취 깔대기(1)의 상부를 개폐시킨다.The measuring instrument is equipped with a collecting funnel (1) capable of receiving rainwater on the upper part, and the collecting funnel (1) is provided with a cover (2) on the upper part, and the cover (2) is rotated on the side of the collecting funnel (1) It is rotated by the motor 4, and opens and closes the upper part of the collecting funnel 1.

이러한 회전모터(4)의 작동은 비가 올 때에만 작동되는 것이 바람직하므로 회전모터(4)에는 강우센서(3)가 연결된다.Since the operation of the rotary motor 4 is preferably operated only when it is raining, the rainfall sensor 3 is connected to the rotary motor 4.

그리고 회전 깔대기(1)의 하부에는 측정 셀(9)이 연통 설치되고, 측정 셀(9)은 내부에 레벨센서(11)와 pH전극(10)이 설치되며, 하부에는 전자 제어에 의해 자동으로 개폐가 되는 제1밸브(9a)가 설치된다.In the lower part of the rotary funnel (1), a measuring cell (9) is installed in communication, and the measuring cell (9) is provided with a level sensor (11) and a pH electrode (10) therein. The 1st valve 9a which opens and closes is provided.

여기서 레벨센서(11)는 측정 셀(9)에 채워지는 빗물의 높낮이를 감지하게 되는 것이고, pH전극(10)은 빗물의 산성도를 측정하게 된다.Here, the level sensor 11 detects the height of the rainwater filled in the measuring cell 9, and the pH electrode 10 measures the acidity of the rainwater.

측정 셀(9)의 하부에는 배수용기(8)가 설치되어 측정 셀(9)로부터 낙하된 빗물을 적정 수위까지 받았다가 배수하게 된다.A drain container 8 is installed in the lower part of the measuring cell 9 to receive rainwater dropped from the measuring cell 9 to an appropriate level and then drain it.

한편, 채취 깔대기(1)와 측정 셀(9)의 사이에는 보관용액, 예를 들어 KCl을 저장하는 저장용기(5)가 연통되고, 연통되는 중간에는 보광용액의 흐름을 제어하는 제2밸브(5a)가 설치된다. 이 제2밸브(5a)는 후술하는 콘트롤 패널에 의해 선택적으로 작동된다.On the other hand, between the collecting funnel 1 and the measuring cell 9, a storage container 5 for storing a storage solution, for example, KCl, is in communication, and in the middle of the communication, a second valve for controlling the flow of the light-retaining solution ( 5a) is installed. This second valve 5a is selectively operated by a control panel described later.

콘트롤 패널(13)은 제1밸브(9a) 및 제2밸브(5a), 그리고 레벨센서(11)와 pH전극(10)이 연결된다.The control panel 13 is connected to the first valve 9a and the second valve 5a, the level sensor 11 and the pH electrode 10.

특히 pH전극(10)은 데이터 로거(6)와 접속되어 빗물의 산성도를 측정한 데이터를 수집하고, 그 정보를 유선이나 무선방식을 통해 원격에 위치한 PC(12)로 전송하게 된다.In particular, the pH electrode 10 is connected to the data logger 6 to collect data measuring the acidity of the rain water, and transmits the information to the PC 12 located remotely via a wired or wireless method.

이상과 같이 구성된 본 발명에 따른 산성비의 산성도 측정기는 다음과 같은 작용을 나타낸다.Acidity meter of the acid rain according to the present invention configured as described above shows the following actions.

먼저 비가 내리게 되면 강우센서(3)에 빗물이 묻어 전류가 통하게 되고, 자동으로 회전모터(4)가 작동하여 덮개(2)를 개방시켜서 채취 깔대기(1)로 빗물이 유입되도록 한다.First, when the rain falls rainwater on the rainfall sensor (3), the current flows through, and the rotary motor (4) is automatically operated to open the cover (2) so that rainwater flows into the collecting funnel (1).

채취 깔대기(1)로 유입된 빗물은 측정 셀(9)로 유입된다. 이때 제1밸브(9a)는 닫혀진 상태임으로 측정 셀(9)에서 빗물의 수위는 점점 높아지게 된다.Rainwater flowing into the harvesting funnel 1 flows into the measuring cell 9. At this time, since the first valve 9a is in a closed state, the level of rainwater in the measuring cell 9 is gradually increased.

그러면 pH전극(10)이 정해진 시간 간격 또는 수위에 따라 측정 셀(9)로 유입된 빗물의 산성도를 측정하고, 그 데이터는 데이터 로거(6)를 통해 원격에 위치한 PC(12)로 전송된다.Then, the pH electrode 10 measures the acidity of the rainwater introduced into the measuring cell 9 at a predetermined time interval or water level, and the data is transmitted to the remotely located PC 12 via the data logger 6.

일정량의 빗물이 측정 셀(9)에 유입되면 레벨센서(11)가 작동하여 자동으로 하단부의 제1밸브(9a)가 열리고, 측정 셀(9)에 채워진 빗물은 배수용기(8)로 배출된다. 측정 셀(9)에서 빗물이 모두 빠져 나가면 제1밸브(9a)는 곧 닫히게 된다.When a certain amount of rainwater enters the measuring cell 9, the level sensor 11 is operated to automatically open the first valve 9a at the lower end, and the rainwater filled in the measuring cell 9 is discharged to the drain container 8. . When all the rain water is discharged from the measuring cell 9, the first valve 9a is closed immediately.

상기 과정은 비가 그칠 때까지 계속 순환 반복되며, 비가 그치면 강우센서(3)의 히터로 인해 빗물이 증발하고, 강우센서(3)에 전류가 연결되지 않으면 회전모터(4)가 다시 작동하여 개방된 채취 깔대기(1)의 상부를 덮개(2)가 닫도록 한다. 이 때 KCl 저장용기(5) 전단부의 제2밸브(5a)가 열려 KCl 용액이 측정 셀(9)로 유입되어 pH 전극(10)을 보관하게 된다.The process is repeated repeatedly until the rain stops, when the rain stops rain water evaporates due to the heater of the rainfall sensor (3), if the current is not connected to the rainfall sensor (3) the rotating motor (4) is opened again to open The cover 2 closes the upper portion of the collecting funnel 1. At this time, the second valve 5a of the front end of the KCl storage container 5 is opened so that the KCl solution flows into the measuring cell 9 to store the pH electrode 10.

이상에서 살펴본 바와 같이 본 발명의 산성비의 산성도 측정기에 의하면, 채취 깔대기로 모아진 빗물을 종래에 비해 상대적으로 작은 측정 셀에서 산성도를 측정하기 때문에 빗물의 양이 많거나 적음에 따라 빗물의 분취하여 정확한 산성도의 측정이 가능하다.As described above, according to the acidic acidity meter of the acid rain of the present invention, since the rainwater collected by the funnel is measured in a relatively small measuring cell, the acidity is measured according to the amount of rainwater or the amount of rainwater, so that the correct acidity is accurate. Can be measured.

또한, 비가 내리지 않을 경우에는 KCl 용액을 측정 셀에 채워 pH 전극을 보호함으로써 추후 빗물의 측정시 데이터의 신뢰도를 높일 수 있다.In addition, when the rain does not fall, the KCl solution is filled in the measuring cell to protect the pH electrode, thereby increasing the reliability of the data when measuring rainwater later.

아울러, 작업자가 측정기가 있는 곳까지 직접 가지 않고서도 사무실 등에서 데이터를 직접 수신할 수 있어 많은 시간을 절약할 수 있다.In addition, it is possible to save a lot of time because the operator can directly receive data in the office, etc. without going directly to the measuring device.
