Description

Non-destructive inspection system {NON DESTRUCTIVE INSPECTION SYSTEM}

The present invention relates to a non-destructive inspection system.

In general, a non-destructive inspection system can inspect internal properties of a product from the outside without destroying the product using non-destructive inspection equipment.

However, when only X-rays are irradiated to the object to be searched in the nondestructive inspection system, the shape of the object to be searched can be obtained, but the material information of the object to be searched cannot be confirmed, and when only neutron rays are irradiated to the object to be searched in the nondestructive inspection system, The material information of the object could be confirmed, but the external form of the object to be searched could not be discerned.

In order to solve this problem, conventionally, a patent document for “a radiation detection device and method capable of detecting neutron rays and X-rays (Registration Patent No. 10-2025662)” has been proposed.

However, in the prior patent literature, since the separation distance from the radiation generator to the object to be searched is fixed at a certain distance, the irradiation distance of X-rays irradiated from the radiation generator to the object to be searched and the irradiation distance of neutron rays irradiated to the object to be searched are the same. However, under the condition that the X-ray irradiation distance and the neutron beam irradiation distance are the same, it is difficult to obtain the material information of the search object accurately through the neutron beam while satisfying the resolution that can accurately discriminate the external shape of the object to be searched through X-rays. .

Accordingly, there is a need for a technology capable of appropriately adjusting the separation distance between the radiation generating device and the object to be scanned according to the type of radiation (X-rays, neutron rays).

In addition, in order to adjust the positions of the X-ray detector and the neutron detector of the radiation detection device 200 to a height corresponding to the subject, the subject is guided by the operation of the second moving unit 340 while being accommodated in the base unit 320. It can be lifted in the Z direction of 1. When the second drive motor 342 is operated, when the second rotation shaft 343a is rotated by the rotation of the drive shaft of the second drive motor 342, the second movement block is rotated by the rotation of the second rotation shaft 343a. (343c) is moved in the vertical direction of the second support frame 341, the base unit 320 can be lifted.

As described above, the present invention can accurately obtain the appearance shape and material information of the subject by appropriately adjusting the separation distance between the radiation generator for irradiating X-rays and neutron rays and the subject, and the separation distance of the subject, Since the height of the subject and the rotation of the subject can be adjusted, it has excellent advantages such as being able to move the projectile to the exact measurement position for measuring X-rays and neutron rays and providing optimal test conditions for the subject. there is.

Although the embodiments of the present invention have been described as specific embodiments, this is merely an example, and the present invention is not limited thereto, and should be construed as having the widest scope according to the basic ideas disclosed herein. A person skilled in the art may implement a pattern of a shape not indicated by combining/substituting the disclosed embodiments, but this also does not deviate from the scope of the present invention. In addition, those skilled in the art can easily change or modify the disclosed embodiments based on this specification, and it is clear that such changes or modifications also fall within the scope of the present invention.
