Description

Technical Field

[0001] The utility model belongs to the technical field of gamma ray flaw detector shielding, and in particular relates to a shielding protection device for a gamma ray flaw detector used for hardware. Background Art

[0002] Radiographic flaw detection is a common method used in industry to inspect the quality of processed hardware. It uses the penetration and linearity of gamma rays to detect defects such as pores and slag inclusions inside hardware. It is simple to operate, has a fast flaw detection speed, and is highly efficient, and is being used more and more widely.

[0003] Existing gamma-ray flaw detectors have a lot of radiation around them when in use, and long-term exposure to the user will damage the user's health. Existing flaw detectors are rarely equipped with shielding and protective devices, which causes users to have a great psychological burden when using them. Some are equipped with protective devices, but the source holes of the protective devices are mostly fixed in size, resulting in a risk of leakage through the source holes when the diameter of the source pipe is small. If the diameter is too large, it is easy to make the source pipe unable to pass through the source hole, causing inconvenience in use. In addition, it is not convenient to change the direction of the flaw detector from the outside, causing inconvenience during flaw detection. For this reason, we propose a shielding and protective device for a gamma-ray flaw detector for hardware. Utility Model Content
