Description
Technical field
The utility model relates to the lossless perspective carrying out flaw detection device of radioactive ray more particularly to the source γ ray nondestructive inspection machines.
Background technique
Gamma-ray detection apparatus is that industrial nondestructive testing field predominantly detects one of equipment, it using the source γ as radioactive source, by
Ray penetrates welding weld bond exposure film making, judges whether tested weld bond is defective according to film imaging.
Since γ source radiation penetration capacity is stronger, if it is larger to human injury not implement effective radiation protection.Therefore, it
Detection scene personnel in film making are asked all to clear out a gathering place.But sometimes or certain specific occasions, as scene has multiplexing kind same
Shi Zuoye, when can not accomplish " irrelevant personnel is withdrawn ", if detection device being capable of effective oriented control γ source radiation range and spoke
The amount of penetrating makes its rediation aperture avoid other incoherent operating personnels, is equally reached the safe handling mesh from radiation injury
's.
When non-destructive testing, there are more strict requirements to the radiation dose rate of place ambient radiation.So needing
A kind of gamma-ray detection apparatus that can routinely use but also be worked with micro- forms of radiation.Supplemental content: " micro- radiation " working condition
Be mainly used in the workplace that can not be cleared out a gathering place: detection scene can not accomplish " irrelevant personnel is withdrawn ", that is, the construction of different work posts
Personnel's operation at the scene simultaneously can avoid other irrelevant personnel since " micro- radiation " working condition has good directionality,
Make them from x ray irradiation x.
Summary of the invention
The purpose of the invention of the present invention is to provide one kind can implement directed radiation and amount of radiation it is controllable, to meet
Operation field, which can not accomplish " irrelevant personnel is withdrawn " again, to be made to detect micro- radiation gamma-rays to the radiationless injury of operating personnel around
Defectoscope.
Micro- radiation gamma-ray detection apparatus technical solution provided by the utility model, main technical content is: a kind of micro- spoke
It penetrates gamma-ray detection apparatus, cylindrical chassis and its forward and backward end plate and forward and backward end cap constitutes the closing setting chamber of the source γ shield, institute
The source the γ shield stated is that fan-shaped shielding sliding block split forms by the shielding main body of axial sliding fit and section, the screen
The front lower portion center that sliding block is located at shielding main body is covered, top is the lower half arc-shaped cavity with shield source channels phase split, shielding master
γ source radiation controllable window is constituted between body and the split end face for shielding sliding block.
In above-mentioned overall technical architecture, shield main body split end face be in the source γ security mask harvesting position before
Side, adjusting radiation controllable window split closing, the control lever for opening and opening size, which are fixed on, to be shielded on slip front face, behaviour
The rod end that control lever draws front end-plate is equipped with adjusting knob.
Be also equipped in above-mentioned overall technical architecture a source move adjuster, the source move adjuster include special connector and
Source is apart from regulation cock out, and the inner screw sheath of regulation cock and special connector is threadedly engaged, before special connector is removably mounted at
On the front connector of end cap, when needing micro- irradiation processes, remaining inner screw sheath is empty because regulation cock screws in for special connector
Between length be the source γ by security mask harvesting be moved to unlatching γ source radiation controllable window center moving distance, shielding sliding block
Moving distance changes γ source radiation controllable window and opens size, and the depth that regulation cock screws in special connector is controllable by γ source radiation
Window is opened size and is determined, micro- radiation carrying out flaw detection is implemented.
Micro- radiation gamma-ray detection apparatus technical solution disclosed by the utility model both there is conventional nondestructive inspection to detect function
It can, additionally it is possible to pull shielding sliding block, unlatching and shield γ source radiation controllable window between main body, the source γ is moved in window
Orientation, micro- radiation nondestructive inspection function of micro radiation are realized in centre, meet pair of the people in addition to conventional nondestructive inspection detection
The demand for micro- radiation nondestructive inspection detection that activity is of less demanding, radiation scope is controllable, is especially suitable for such as operation scene
The inferior safe carrying out flaw detection of the special circumstances that full complement can not be made to clear out a gathering place operates with.The technical program contexture is simple,
It is easy to operate and control, the dual optional function with conventional detection and micro- radiation detection.
Detailed description of the invention
Fig. 1 is the appearance assumption diagram of the utility model.
Fig. 2 is the section view scantling plan of the utility model.
Fig. 3 is the axial arrangement figure of the source γ shield.
Specific embodiment
Micro- radiation gamma-ray detection apparatus disclosed by the utility model, cylindrical chassis 11 and its forward and backward end plate 1,2 and forward and backward
Chamber is arranged in the closing that end cap 4,3 constitutes the source γ shield.The source the γ shield by axial sliding fit shielding main body 20
It is fan-shaped 21 split of shielding sliding block composition with section；The shielding sliding block 21 is located at the front lower portion center of shielding main body 20,
Top is the lower half arc-shaped cavity with the 19 phase split of shield source channels, and two sides are with shielding 20 phase split of main body and slide-and-guide is matched
The slideway 12 of conjunction.
The split end face for shielding main body 20 is fixed end face, before which is in 23 security mask of the source γ harvesting position
Side, adjusting radiation 22 split of controllable window closing, the control lever 33 for opening and opening size, which are fixed on, shields 21 front end of sliding block
On face, the rod end that control lever 33 draws drive end bearing bracket 4 is equipped with adjusting knob 34.The mobile position of shielding sliding block 21 is controlled by adjusting knob 34
It sets, and then controls and turn off or on γ source radiation controllable window 22 between shielding sliding block 21 and shielding 20 split end face of main body, and
It controls γ source radiation controllable window 22 and opens size.
This micro- radiation gamma-ray detection apparatus is also equipped with one and moves adjuster with the source that the front connector of drive end bearing bracket is detachably connected.
