Description

진동 측정용 피그 장치{pig apparatus for measuring vibration}[0001] The present invention relates to a pig apparatus for measuring vibration,

본 발명은 진동 측정용 피그 장치에 관한 것으로서, 상세하게는 관의 내부를 주행하면서 검출되는 진동 및 주행거리정보를 매칭되게 기록하여 열람 가능하게 제공할 수 있도록 된 진동 측정용 피그 장치에 관한 것이다.The present invention relates to a vibration measuring apparatus, and more particularly, to a vibration measuring apparatus capable of detecting vibration and running distance information while running inside the tube so that the information can be recorded in a matching manner.

일반적으로, 가스 또는 유류와 같이 유체가 흐르는 관(pipe)의 내부에는 유체에 함유된 물질이 관의 내측면에 적층되어 스케일이 형성된다. 이러한 스케일은 관의 내경을 줄여 유체의 흐름에 방해를 일으키게 된다.Generally, in a pipe through which a fluid flows, such as gas or oil, materials contained in the fluid are stacked on the inner surface of the pipe to form a scale. These scales reduce the inner diameter of the tube, which can interfere with the fluid flow.

이와 같이 관이 내측면 형성된 스케일을 제거하기 위해 일반적으로 피그(pig) 장치가 이용된다. A pig apparatus is generally used to remove the scales formed on the inner side of the pipe.

세척과정은 관로 내에 피그장치를 투입한 다음 고압의 공기 또는 세척수를 주입하여 피그장치가 관로를 따라 이동하면서 스케일을 접촉에 의해 제거하도록 진행된다. The cleaning process is carried out by introducing a pig device into the channel and then injecting high pressure air or wash water to remove the scale by contact as the pig device moves along the channel.

피그본체(110)는 관(10)의 내부를 이송하면서 이물질 또는 스케일과 같이 관의 내측면에서 내부를 향하여 돌출된 제거대상요소(13)를 접촉에 의해 분리하여 세척할 수 있게 몸통부분(112)의 외경이 결정된다.The main body 110 is provided with a body portion 112 for separating and cleaning the removal subject element 13 protruding inwardly from the inner side surface of the tube such as a foreign substance or scale while contacting the inside of the tube 10, Is determined.

피그 본체(110)의 몸통부분(112)으로부터 전방으로 연장된 선두부분(113)은 진입저항을 줄일 수 있도록 몸통부분(112)으로부터 점진적으로 외경이 좁아지게 형성된 구조로 형성되어 있다.The head portion 113 extending forward from the body portion 112 of the main body 110 is formed to have a gradually reduced outer diameter from the body portion 112 so as to reduce the entry resistance.

피그 본체(110)의 형상은 도시된 형상 이외에도 관(10) 내에서 고압의 공기 또는 고압의 세척수에 의해 이동하면서 관(10) 내부와의 접촉에 의해 이물질을 제거할 수 있는 다양한 형상의 것이 적용될 수 있음은 물론이다. The shape of the pig body 110 may be various shapes that can remove foreign matter by contact with the inside of the pipe 10 while being moved by high pressure air or high pressure washing water in the pipe 10 Of course.

주행거리 측정부(120)는 피그본체(110)에 결합되어 피그본체(110)의 이송거리를 측정한다.The travel distance measuring unit 120 is coupled to the pig body 110 to measure the distance traveled by the pig body 110.

여기서, 휠(122)을 지지하는 아암(114)은 관(10)의 내경이 줄어드게 돌출된 요소에 의해 휠(122)이 가압될 때 피그본체(110)의 중앙을 향하는 방향으로 탄성적으로 회동될 수 있게 되어 있다.Here, the arm 114 supporting the wheel 122 is resiliently moved in the direction toward the center of the main body 110 when the wheel 122 is pressed by an element protruding to reduce the inner diameter of the tube 10 So that it can be pivoted.

휠(122)의 회전은 엔코더 또는 홀센서를 이용하여 측정하도록 구축될 수 있다.The rotation of the wheel 122 may be constructed to measure using an encoder or a Hall sensor.

주행거리 측정부(120)는 휠(122)의 회전값에 대응되는 주행거리를 산출하여 제어부(152)에 실시간으로 제공한다.The travel distance measuring unit 120 calculates the travel distance corresponding to the rotation value of the wheel 122 and provides the calculated travel distance to the control unit 152 in real time.

진동검출센서(130)는 진동의 세기를 검출할 수 있는 압전진동센서 등 공지된 다양한 것이 적용될 수 있다.The vibration detection sensor 130 may be any of various known types such as a piezoelectric vibration sensor capable of detecting the intensity of vibration.

진동검출센서(130)는 관(10)의 내측면에 고착된 제거대상요소(13)와의 접촉진동을 용이하게 검출할 수 있도록 피그 본체(110)에 설치되면 된다.The vibration detection sensor 130 may be installed on the main body 110 to easily detect the contact vibration with the removal target element 13 fixed to the inner surface of the tube 10. [

제어유니트(150)는 제어부(152)와 기억부(150)를 구비한다.The control unit 150 includes a control unit 152 and a storage unit 150.

제어부(152)는 피그본체(152)에 장착되며 진동기록모드로 설정되면 주행거리 측정부(120)에서 측정되는 주행거리정보와 진동검출센서(130)에서 검출된 진동신호를 상호 매칭시켜 기억부(154)에 기록되게 처리한다.The control unit 152 is mounted on the main body 152. When the vibration recording mode is set, the control unit 152 matches the traveling distance information measured by the traveling distance measuring unit 120 with the vibration signal detected by the vibration detecting sensor 130, (154).

기억부(154)는 메모리카드와 같이 피그본체(110)에 대해 탈착가능하게 구축된 것이 바람직하다.It is preferable that the storage unit 154 is detachably mountable to the pig body 110 like a memory card.

인터페이스부(156)는 기억부(154)에 기록된 정보를 컴퓨터 또는 그 밖의 외부전자기기에 전송하는 것을 지원할 수 있도록 마련되어 있다.The interface unit 156 is provided to support transferring the information recorded in the storage unit 154 to a computer or other external electronic device.

인터페이스부(156)는 USB인터페이스가 적용될 수 있다.The interface unit 156 may be a USB interface.

이러한 피그 장치(100)는 세척과정을 수행한 후 기억부(154)에 주행거리에 대응되게 기록된 진동신호로부터 관(10) 내부의 상태를 분석할 수 있다.The apparatus 100 may analyze the state of the pipe 10 from the vibration signal recorded in the storage unit 154 in correspondence with the travel distance after performing the cleaning process.

즉, 관(10) 내에 고착된 제거대상 요소(13)의 강도가 강하고 제거되기 어려운 경우 진동 세기가 크고, 쉽게 제거되는 요소는 진동세기가 약하며 지나가는 과정에서 진동세기가 감쇠되는 특성을 갖는다. 따라서 검출된 진동세기 정보로부터 관(10) 내부의 고착요소의 상태를 파악하는데 이용할 수 있다.That is, when the strength of the removal subject element 13 fixed in the tube 10 is strong and difficult to remove, the vibration intensity is large, and the easily removable element has weak vibration intensity and has a characteristic in which the vibration intensity is attenuated in the process of passing. Therefore, it can be used to grasp the state of the fixing element inside the tube 10 from the detected vibration intensity information.

또한, 관(10) 내부의 부식에 의해 돌출되어 발생된 부식요소와의 접촉시 검출되는 진동 등에 대해서도 실험적으로 확보된 진동정보가 있으면, 검출된 진동정보로부터 부식요소의 발생여부 및 위치도 확인할 수 있는 등 정밀진단용으로 다양하게 활용할 수 있다.Further, if there is vibration information obtained experimentally for vibrations detected upon contact with a corrosion element protruding and generated by corrosion inside the pipe 10, whether or not the corrosion element is generated and the position can be confirmed from the detected vibration information It can be used variously for precision diagnosis.

참조부호 180은 전력공급용 배터리이다.Reference numeral 180 denotes a battery for power supply.

이상에서 설명된 진동 측정용 피그 장치에 의하면, 관 내부를 세척하기 위해 주행되는 과정에서 센싱된 진동정보를 주행거리정보와 매칭시켜 제공할 수 있어 관 내부의 정밀진단이 요구되는 부분을 용이하게 파악할 수 있는 장점을 제공한다. According to the above-described vibration measuring apparatus, it is possible to match the sensed vibration information with the traveling distance information during the course of running for cleaning the interior of the pipe, thereby easily identifying the portion requiring precise diagnosis inside the pipe It offers the advantage of being able to.
