Description
Technical field
The utility model relates to the used solid-state detector modules device of radiation image-forming system, belongs to the radiation checking technical field.
Background technology
The detector module that the container check system of prior art uses, the most using gases detectors of its detector.The shell structure of the gas detector module of being made up of gas detector is rectangular basically, owing to be subjected to the restriction of structure, brings the inconvenience of many uses in the actual installation dismounting, exists the bigger shortcoming of volume.At present in container check system, also form solid-state detector modules by using solid probe, its array configuration is to arrange solid probe on a printed circuit board (PCB) basically, in use because the influence that is subjected to x ray irradiation x of front-end circuit and photodiode, cause and check that imaging effect is relatively poor and shortened serviceable life, in case and in a single day this kind structure check system go wrong, maintenance is difficulty very.The applicant has applied for a Chinese patent for this reason, and application number is 02289767.4, and name is called " the radiant image solid probe is touched block structure ".Not only volume is little for it, and has reduced the x ray irradiation x to front-end circuit and photodiode, can make to check the imaging effect raising and be convenient to module interior circuit debugging, maintenance and assembling.But the problem that also has anti-scattering difference in actual applications.
Summary of the invention
At above-mentioned the problems of the prior art, goal of the invention of the present utility model is to do further improvement on the basis of No. 02289767.4 patented technology, provides another kind to be used for the detector modular structure of radiant image.Not only volume is little for it, assembling, debugging, easy to maintenance, and the x ray irradiation x of front-end circuit is little, and can reduce perpendicular to the scattering on the line face and disturb, and overcomes on the line face scattering to the influence of detector.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
The detector modular structure that is used for radiant image, it comprises housing, base plate and the solid detector array plate of being made up of a plurality of solid probes.Described housing is
Type, its bottom and described base plate are fixed.Be equipped with described solid detector array plate on the below of housing, the base plate, housing is built-in with support wiring board is fixed, and the front end face of housing is equipped with connected each socket, and the upper end of housing is fitted with the upper cover plate of being convenient to part loading and unloading in the shell with its form fit.Its design feature is that the front end edge of described solid detector array plate is along the collimating apparatus that has been equipped with collimation and anti-scattering process.
According to above-mentioned technical scheme, described collimating apparatus is made up of last frid, multi-disc dividing plate, following frid.Following frid is fixed by bracing frame and base plate, and each sheet dividing plate is flush-mounted in down between frid and the last frid, and the quantity at the interval that is formed by each sheet dividing plate is consistent with the quantity of solid probe.
According to above-mentioned technical scheme, described upper cover plate is the type, by the upper end sealing of trip bolt with itself and housing.
According to above-mentioned technical scheme, the rear end face of described housing is equipped with the bonnet of being convenient to part loading and unloading in the shell.
According to above-mentioned technical scheme, be equipped with the lead of shielding action between described inner walls and the support bearing.
The utility model in use very is convenient to the installation and removal of wiring board in the housing owing to adopted said structure, windows because the rear end face of housing is provided with, and is convenient to being connected of detector array strake and front-end circuit plate, the fixing of base plate and shell.In addition owing to add collimating apparatus at the detector front end edge, can select the collimating apparatus of different length material for use for the ray of different-energy, not only reduced the irradiation damage of photodiode, and reduced along the line face with perpendicular to the various scatterings of line face.Because the front-end circuit plate is not installed on the line face of ray, therefore also reduced the irradiation of ray front-end circuit, the serviceable life of having improved detector module again.The utility model compared with prior art, significantly reduced along the line face with perpendicular to the various scatterings of line face, improved the anti-scattering property of detector module, help improving the sharpness of image, very favourable for using sigmatron and not establishing the application of the back radiation imaging check system of collimating apparatus.
