본 발명은 절연유 점도 유지용 가열수단이 구비된 엑스선 검색기에 관한 것으로, 더욱 자세하게는 동절기 등에 낮은 기온으로 인해 엑스선 검색기의 내부에 설치되는 엑스선 발생장치 속에 충전된 절연유의 점도를 유지시켜 엑스선 검색기의 동작불량을 해소하여 초기 가동이 원활하게 이루어질 수 있도록 한 것이다.The present invention relates to an X-ray searcher equipped with a heating means for maintaining the insulating oil viscosity, and more particularly, the operation of the X-ray searcher by maintaining the viscosity of the insulating oil filled in the X-ray generator installed inside the X-ray searcher due to the low temperature in winter, etc. Eliminating the defects to ensure the initial operation smoothly.

일반적으로 엑스선 검색기는 공항이나 항만 등에 출입하는 많은 사람들이 소지한 소지품 중에 신고하지 않고 밀반입하거나 밀반출하는 물품이나 총기류 및 폭탄 등의 위험물을 소지하였는지를 신속하게 검사할 수 있도록 한 장비이다. In general, an X-ray scanner is a device that allows a large number of people who enter and exit an airport or harbor to quickly check whether they carry dangerous goods such as firearms and bombs, or smuggled in or out of possession.

엑스선 검색기는 비행기나 배 등을 이용하여 여행을 하는 승객이 휴대한 소지품이 든 가방을 검색기 내로 투입하면 엑스선(X-RAY)을 투시하여 소지품을 판독할 수 있는 영상을 획득하여 소지품 중에 총기류나 폭탄 등의 위험한 물건과 마약이나 밀반입 또는 밀반출 되는 물품이 없는지를 신속하게 검사하여 검색의 지체에 따른 승객의 불편을 최소화 하면서 안전하고 편안한 여행을 이룰 수 있도록 도와주는 장비로 공항이나 항만 등에는 필수적으로 설치되어 있는 장비이다.The X-ray scanner puts a bag containing belongings carried by passengers traveling by plane or ship into the scanner and obtains an image to read the X-rays to read the belongings. It is a device that helps to make a safe and comfortable trip while minimizing the inconvenience of passengers due to the delay of search by promptly checking whether there are dangerous objects such as drugs and smuggled or smuggled goods. Equipment.

통상 엑스선 검색기의 내부 공간에는 엑스선 발생장치가 설치되어 발생된 엑스선이 검색기내로 투입된 가방이나 짐을 투시하여 소지품의 판독을 이룰 수 있도록 하는 것으로 엑스선 발생장치는 목표물(target)에 가속전자를 조사해서 엑스선을 발생시키는 방식이 채택되고 있다. In general, an X-ray generator is installed in an internal space of an X-ray scanner so that the generated X-rays can read a bag or baggage put into the scanner to read the belongings. The X-ray generator emits X-rays by irradiating accelerating electrons to a target. The method of generating is adopted.

그런데, 수만 볼트의 전압으로 가속되는 전자가 목표물에 충돌할 때에, 그 가속전자 에너지중 엑스선에너지로서 인출되는 효율은 겨우 1%정도이고, 나머지의 약 99%는 줄(Joule)열로서 소비되어 버린다. However, when electrons accelerated to a target voltage of tens of thousands of volts collide with the target, the efficiency of being extracted as X-ray energy of the accelerated electron energy is only about 1%, and the remaining 99% is consumed as Joule heat. .

따라서, 엑스선 발생장치 속에는 발생된 열 및 전기를 절연시켜 과열로 인한 동작불능이나 오동작을 방지하기 위하여 절연유를 충전하여 절연을 이루도록 하는 것이다.Therefore, the X-ray generator is to insulate the generated heat and electricity to insulate by filling the insulating oil in order to prevent malfunction or malfunction due to overheating.

그러나, 엑스선 발생장치 안에 충전된 절연유는 동절기 등에 외부 기온이 낮아지면 쉽게 굳어지면서 점도가 높아져 전자의 가속을 방해하게 되고 이로 인하여 엑스선 발생장치가 원활하게 동작되지 못한다는 문제점이 있었다.However, the insulating oil charged in the X-ray generator has a problem that it hardens easily when the external temperature is lowered in winter, and the viscosity increases, thereby preventing the acceleration of electrons, and thus the X-ray generator does not operate smoothly.

본 발명은 상기한 바와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 동절기 등에 외부 기온이 낮아져 엑스선 발생장치 속에 충전된 절연유의 점성이 높아지는 않게 하여 엑스선 검색기가 원활하게 동작되어지도록 하기 위한 것으로The present invention is to solve the problems as described above, the object of the present invention is to allow the X-ray searcher to operate smoothly so that the external temperature is lowered in winter, the viscosity of the insulating oil charged in the X-ray generator is not increased.

본 발명의 목적은 함체상의 엑스선 검색기 본체 내부로 컨베이어 등의 이송수단을 통해 이송된 검색대상에 엑스선 발생장치에서 발생된 엑스선을 투과시켜 투과된 엑스선을 수광하여 변환 출력한 영상신호로 수신하여 모니터를 통해 검색 대상물의 구성이나 상태를 파악할 수 있도록 한 엑스선 검색기에 있어서, 상기 엑스선 발생장치에는 온도측정수단 및 가열수단을 부가 형성하고 상기 온도측정수단의 측정값을 전달받아 가열수단을 제어하기 위한 제어부를 형성하여 측정된 온도가 기준치 이하인 경우에는 가열수단을 동작시켜 절연유의 점도를 유지할 수 있도록 한 것이다. An object of the present invention is to receive a monitor by receiving the converted X-rays received as a video signal transmitted through the X-rays generated by the X-ray generator to the search target transferred through the conveying means such as a conveyor into the main body of the X-ray detector on the enclosure In the X-ray searcher to determine the configuration or state of the object to be searched through, the X-ray generator is provided with a temperature measuring means and a heating means, and a control unit for controlling the heating means by receiving the measurement value of the temperature measuring means If the formed measured temperature is less than the reference value it is to operate the heating means to maintain the viscosity of the insulating oil.

본 발명은 동절기 등에 기온이 낮아져 엑스선 발생장치의 절연유가 고점성률을 가지거나 굳어지는 것을 예방하여 엑스선 검색기의 초기 가동시 절연유의 점도를 내리기 위해 대기하여야 하는 시간을 필요로 하지 않음으로서 검색의 지체를 방지할 수 있다는 효과가 있다. The present invention prevents the delay of the search by not having to wait for the viscosity of the insulating oil during the initial operation of the X-ray detector by preventing the insulating oil of the X-ray generator having a high viscosity rate or hardening due to the temperature decrease in winter or the like. There is an effect that can be prevented.
