풍량측정장치{Airflow measuring equipment}Airflow measuring equipment

본 발명은 풍량측정장치에 관한 것으로, 더욱 상세하게는 덕트와 같은 바람이 흐르는 곳에 설치하여 풍속을 측정하는 풍량측정장치에 있어서, 사각박스형에 몸체케이스, 바람에 의해 회전하는 회전장치부, 회전장치부를 보호하는 사각망형태에 팬보호망덮개, 회전장치부에 회전판 바닥면에 감지표시구를 인식하는 회전감지센서를 갖는 센서기판으로 구비한 풍량측정장치에 관한 기술이다.The present invention relates to an air volume measuring device, and more particularly, in an air volume measuring device installed in a place where wind flows such as a duct to measure wind speed, a body case in a square box type, a rotating device part rotating by wind, a rotating device It is a technology related to the air volume measurement device equipped with a sensor substrate having a fan protection net cover in the form of a rectangular net to protect the part, and a rotation detection sensor that recognizes the detection indicator on the bottom of the rotating plate in the rotating device.

일반적으로 덕트시스템과 같은 공기를 공급하는 장치를 사용함에 있어서 원활한 공기를 공급하기 위하여 토출되는 공기의 풍량 측정에 정확성을 요구하고 있다.In general, in using an air supply device such as a duct system, accuracy is required in measuring the air volume of discharged air in order to supply air smoothly.

일반적으로 풍량을 측정하는 측정장치는 바람에 의해 회전하는 회전날개의 축이 스위치에 직접 접촉하여 카운팅 되어 측정하거나, 회전축에 자석파트를 결속하여 측면에 가변저항에 변위를 측정하여 감지하는 방법이 사용되고 있다.In general, as a measuring device for measuring the air volume, the axis of the rotating blade rotating by the wind is directly contacted with the switch to measure it, or a method of measuring the displacement by a variable resistance on the side by binding a magnetic part to the rotating shaft is used. have.

하지만, 직접 접촉하여 카운팅 되는 방식은 회전에 저항을 주어서 풍량측정에 정확성을 감소시키는 문제점이 있었으며, 또한, 자석파트를 결속한 회전날개의 경우 자석파트에 무게로 인한 회전에 영향을 주며 변위측정에 따른 정확한 회전수를 측정함에 있어서 오차가 발생할 수 있다는 문제점이 있었다.However, the direct contact and counting method has a problem of reducing the accuracy of air volume measurement by giving resistance to rotation, and also, in the case of a rotating blade that binds a magnetic part, it affects the rotation due to the weight of the magnetic part, and is used for measuring displacement. There is a problem that an error may occur in measuring the exact number of rotations.

또한, 기존 풍량측정장치에 회전날개는 바람에 의해 회전하다가 바람이 불지 않아도 자체 원심력에 의하여 회전되서 풍량의 측정에 오차 값이 발생한다는 문제점이 있었다.In addition, there is a problem in that the rotating blade rotates by its own centrifugal force even if the wind does not blow, resulting in an error value in the measurement of the air volume.

이에 본 발명은 풍량측정기를 사용함에 있어서, 풍량측정에 발생하는 오차에 문제점을 감소하고자 하는 것을 그 목적으로 하는 것이다.Accordingly, it is an object of the present invention to reduce a problem in an error occurring in air volume measurement when using an air volume meter.

이를 위해 본 발명은 풍량측정장치에 있어서, 사각박스형에 몸체케이스, 바람에 의해 회전하는 회전장치부, 회전장치부를 보호하는 사각망형태에 팬보호망덮개, 회전장치부에 회전판 바닥면에 감지표시구를 인식하는 회전감지센서를 갖는 센서기판으로 구비하고, 상기 팬보호망덮개와 몸체케이스에 결속을 모서리 하나만을 나사 결속하는 포인트결속구조로 구비하고, 회전장치부의 회전판 바닥면에 감지표시구와 동일질량에 편심보정구를 구비하고, 회전장치부가 바람이 불 때에만 회전하도록 하는 회전정지장치와 회전감지센서의 사이에 오염물을 확인하는 이물질확인센서를 구비한 풍량측정장치를 제공하는 것이다.To this end, the present invention relates to an air volume measuring device, a body case in a square box type, a rotating device part rotating by wind, a fan protection net cover in a square net form protecting the rotating device part, and a sensing indicator on the bottom surface of the rotating plate in the rotating device part. It is provided as a sensor substrate having a rotation detection sensor that recognizes the fan protection net cover and the body case, and is provided with a point connection structure in which only one edge is screwed, and the same mass as the detection indicator on the bottom surface of the rotating plate of the rotating device It is provided with an eccentricity correction device, to provide an air volume measuring device having a foreign matter check sensor between the rotation detection sensor and a rotation stop device that allows the rotation device to rotate only when the wind blows.

따라서 본 발명은 풍량측정장치를 회전장치부에 회전하는 회전판 하부바닥 절반에 감지표시구를 구비하고 이를 인식하는 회전감지센서를 구비하여 실기하게 되면 바람에 의해 회전장치부가 회전하고 이와 함께 회전판이 회전하면 상기 회전감지센서가 회전판의 감지표시구를 근접함을 인식하여 회전장치부의 회전수를 확인하고 이를 통해 풍속을 측정하는 것이다.Therefore, in the present invention, when the air volume measurement device is provided with a detection indicator on the lower half of the rotating plate rotating in the rotating device and a rotation detection sensor that recognizes it, the rotating device rotates by the wind and the rotating plate rotates with it.
