Conventional small-capacity pumps can recognize the rotational direction in advance and start the installation work, but there is no way for a large-capacity submersible pump to recognize the rotational direction of the pump. The inspection resulted in time and economic waste.

본 발명에 의한 펌프의 회전방향 감지방법은 펌프의 회전방향을 감지하는 방법에 있어서, 펌프의 회전축에는 자석이 구비된 자석연장축이 부착되고, 상기 자석에 인접하도록 자기형리드스위치가 설치되되, 유도전류가 발생되도록 회로구성된 코일1과 코일2의 사이에 자기형리드스위치를 전기적으로 연결하고, 상기 코일1,2 및 자기형리드스위치에 의해 형성되는 전기적 회로에 2개의 발광다이오드를 서로 반대방향이 되도록 병렬연결 또는 볼트미터(Volt Meter)를 연결하여 펌프의 회전방향을 측정하는 것을 그 기술적 특징으로 한다. In the method of detecting the rotational direction of the pump according to the present invention, in the method of detecting the rotational direction of the pump, a magnet extension shaft with a magnet is attached to the rotational axis of the pump, and a magnetic lead switch is installed to be adjacent to the magnet.

이하에서는 본 발명에 의한 펌프의 회전감지방법을 첨부한 도면을 참고하여 상세히 설명한다. Hereinafter, with reference to the accompanying drawings, the rotation detection method of the pump according to the present invention will be described in detail.

도 1은 본 발명의 일 실시례로서 펌프의 회전축과 발전장치의 연장축을 밀착 회전시켜 볼트미터로 전류의 방향을 계측함으로써 펌프의 회전방향을 측정하는 방법을 개략적으로 나타낸 모식도이고, 도 2a는 본 발명의 다른 실시례로서 펌프의 회전축에 자석연장축을 밀착시키고, 상기 자석연장축을 자기형리드스위치 및 코일에 근접시켜 발생되는 유도전류에 의해 펌프의 회전방향을 측정하는 방법을 개략적으로 나타낸 모식도이고, 도 2b는 유도전류의 일반적인 전류파형도이고, 도 2c 및 2d는 본 발명의 자기형리드스위치가 설치된 상태에서 펌프의 정회전 또는 역회전시 유도전류의 전류파형도이고, 도 3a 내지 3c는 본 발명의 전자유도현상을 개략적으로 나타내는 모식도 및 전류파형도이다.1 is a schematic diagram schematically showing a method of measuring the rotational direction of the pump by measuring the direction of the current in voltmeter by closely rotating the rotational axis of the pump and the extension shaft of the power generator as an embodiment of the present invention, Figure 2a As another embodiment of the invention is a schematic diagram showing a method of measuring the rotational direction of the pump by the induction current generated by bringing the magnetic extension axis in close contact with the rotation axis of the pump and the magnetic extension axis close to the magnetic lead switch and the coil, Figure 2b is a general current waveform diagram of the induction current, Figures 2c and 2d is a current waveform diagram of the induction current at the forward or reverse rotation of the pump with the magnetic lead switch of the present invention is installed, Figures 3a to 3c Schematic diagram and current waveform diagram schematically showing the electron induction phenomenon of the invention.

본 발명의 일 실시례로서, 도 1에 도시된 바와 같이 펌프(10)의 회전축(11)에 발전장치(50)의 연장축(51)을 밀착 회전시켜 펌프(10)의 회전방향을 감지할 수 있다. As an embodiment of the present invention, as shown in Figure 1 by rotating the extension shaft 51 of the generator 50 in close contact with the rotary shaft 11 of the pump 10 to detect the rotation direction of the pump 10 Can be.

즉, 발전장치(50)의 경우, 회전방향에 따라 출력단자에서 측정되는 전위차의 극성이 상이하게 되는데, 본 발명에서는 상기 발전장치(50)에 전류의 방향 및 크기를 표시하는 볼트미터(Volt Meter)(60)를 직렬로 연결하여 이를 측정할 수 있게 된다. That is, in the case of the generator 50, the polarity of the potential difference measured at the output terminal is different according to the rotation direction. In the present invention, a voltage meter indicating the direction and magnitude of the current in the generator 50. ) 60 can be connected in series to measure it.

이때, 회전방향에 따라 전류의 방향 또는 전위차의 극성이 상이하게 나타나는 것은 종래의 일반적인 공지기술이므로, 이하에서 그 구체적인 설명은 생략한다.At this time, since the polarity of the direction of the current or the potential difference is different according to the rotation direction, it is a conventional general known technology, and the detailed description thereof will be omitted below.

한편, 본 발명의 다른 실시례로서 발전장치(50)을 생략하여 구성할 수도 있다. Meanwhile, as another embodiment of the present invention, the power generator 50 may be omitted.

즉, 도 2a에 도시된 바와 같이, 펌프(10)의 회전축(11)에 자석이 구비된 자석연장축(73)을 밀착 회전시키고, 상기 자석에 인접하도록 자기형리드스위치(74)를 설치하여 펌프의 회전방향을 측정할 수 있게 된다. That is, as shown in FIG. 2A, the magnetic extension shaft 73 with the magnet is rotated in close contact with the rotation shaft 11 of the pump 10, and the magnetic lead switch 74 is installed to be adjacent to the magnet. The direction of rotation of the pump can be measured.

이를 위해 유도전류가 발생되도록 회로구성된 코일1(71)과 코일2(72)의 사이에 자기형리드스위치(74)를 전기적으로 연결하고, 상기 자기형리드스위치(74)에 인접한 펌프(10)의 자석연장축(51)이 회전하면, 특정극(예를 들면, N극)에서 자기형리드스위치(74)의 접점이 온(ON)이 되는 전기적 신호가 발생된다.To this end, the magnetic lead switch 74 is electrically connected between the coil 1 71 and the coil 2 72 configured to generate an induction current, and the pump 10 adjacent to the magnetic lead switch 74. When the magnet extension shaft 51 rotates, an electrical signal is generated in which the contact of the magnetic lead switch 74 is turned ON at a specific pole (for example, N pole).

이는 회전방향에 의해 결정되는 힘(F)과, 자석에서 발생하는 자속밀도(B), 코일에서 유도되는 전류(I) 사이의 방향성 및 크기를 나타내는 플레밍의 오른손법칙에 그 이론적 근거가 있다.This is based on Fleming's right hand law, which indicates the direction and magnitude between the force F determined by the direction of rotation, the magnetic flux density B generated in the magnet, and the current I induced in the coil.

따라서, 도 2b에 도시된 바와 같이 일반적인 싸인파(sin wave)를 나타내는 전기적 신호가 리드스위치에 의해 도 2c에 도시된 바와 같이 펌프가 정회전하여 N 극이 인접하는 순간에는 (+) 신호가 발생하고, 도 2d에 도시된 바와 같이 펌프가 역회전하여 N극이 멀어지는 순간에는 (-)신호가 발생하게 되므로, (+)신호가 측정되면 정방향 회전으로 인지하고, (-)신호가 측정되면 역방향 회전으로 인지하게 된다. Therefore, as shown in FIG. 2B, an electrical signal representing a general sin wave is generated by a reed switch, and a positive signal is generated when the N pole is adjacent to the pump as shown in FIG. 2C. As shown in FIG. 2D, when the pump rotates in reverse direction and the N pole is far away, a negative signal is generated. Therefore, when the positive signal is measured, the positive rotation is recognized, and when the negative signal is measured, the reverse rotation is performed. Will be recognized.

이때, 상기 코일(71)(72) 및 자기형리드스위치에 의해 형성되는 전기적 회로에 각각의 단방향에서만 점등되는 2개의 발광다이오드(75)를 서로 반대방향이 되도록 병렬연결하거나, 전류의 방향 및 크기를 표시하는 볼트미터(Volt Meter)(60)를 직렬로 연결하여 펌프의 회전방향을 측정할 수 있게 된다. At this time, the two light emitting diodes 75, which are turned on only in one unidirectional direction, are connected in parallel to each other in the electrical circuit formed by the coils 71 and 72 and the magnetic type lead switch, or the direction and magnitude of the current. It is possible to measure the rotation direction of the pump by connecting in series a Volt Meter (Volt Meter) (60) indicating.

이하에서는 이해의 편의를 돕기 위해, 본 발명에 적용된 원리를 도 3a 내지 3c에 의해 보다 상세히 설명한다. Hereinafter, in order to facilitate the understanding, the principle applied to the present invention will be described in more detail with reference to FIGS. 3A to 3C.

도 3a에 도시된 바와 같이, 코일의 인접한 위치에서 자석이 회전하면, 전자유도현상에 의해 코일에서는 소정의 전류 파형이 나타나게 되며, 상기 코일의 전단 또는 후단에 온/오프 동작을 수행하는 N형 리드스위치를 부착하면 제한적인 전류파형을 획득할 수 있게 된다. As shown in FIG. 3A, when a magnet rotates in an adjacent position of the coil, a predetermined current waveform appears in the coil due to electromagnetic induction, and an N-type lead performing an on / off operation at the front or the rear of the coil. By attaching a switch, a limited current waveform can be obtained.

즉, 도 3b에 도시된 바와 같이 자석이 정방향 회전시 코일에서는 N형 리드스위치에 의해 빗금친 (+) 영역에서만 전류가 유도되고, 도 3c에 도시된 바와 같이 자석이 역방향 회전시 코일에서는 빗금친 (-) 영역에서만 전류가 유도되는 것이다.That is, as shown in FIG. 3B, the current is induced only in the area of the coil that is hatched by the N-type reed switch when the magnet is rotated in the forward direction. As shown in FIG. The current is induced only in the negative region.

다시말해, 본 발명에서는 코일에 N극이 정회전으로 접근할 때와 역회전으로 멀어질 때에는 전류의 방향이 반대가 되는 플레밍의 오른손법칙을 응용하여 펌프의 회전방향을 인지할 수 있게 된다. In other words, in the present invention, when the N pole approaches the coil in the forward rotation and away from the reverse rotation, the rotational direction of the pump can be recognized by applying Fleming's right-hand rule in which the direction of the current is reversed.

상기와 같은 본 발명은 상술한 특정의 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.The present invention as described above is not limited to the above-described specific embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various changes without departing from the gist of the present invention as claimed in the claims. will be.
