Problems solved by technology

The system has a relatively complicated drag device, which can drag the radiation source, detector, collimator, etc. to reciprocate on the track, but this single movement makes the radiation source move when the target point of the radiation source is aligned with the bottom of the container. The distance is larger, which increases the footprint of the entire system
Therefore, the above-mentioned existing container inspection system has the disadvantages that the project occupies a large area and it is difficult to focus on the suspected area.

Embodiment Construction

[0015] see figure 1 and figure 2 The system of the present invention includes a detector arm frame 15, a collimator 2 13, a collimator 2 13, and a containerized cargo that can be carried by a curved beam or a combination of a beam and a vertical beam, and a detector is installed in the scanning channel. / The vehicle passes through the dragging device 14 of the scanning passage, and the accelerator frame on which the accelerator 6 is housed. The rays of the accelerator 6 face the corrector 11 and the collimator one 12 which are placed in sequence. The first collimator 12 faces the second collimator 13 so that the cone-shaped X-rays emitted by the accelerator 6 are adjusted and transformed into a fan shape, and then pass through the inspected object and be received by the detector in the detector arm frame 15 . The accelerator frame is composed of a horizontal adjustment mechanism 5, a vertical adjustment mechanism 4, a rotation adjustment mechanism 3, a pitch adjustment mech...

Abstract

A container cargo / vehicle examine system with adjustable radiation ray angles includes a detector arm frame with a detector, collimator2, a drag device and an accelerator frame with accelerator, rays of which are opposite to the orderly placed corrector and collimator 1 and 2, characterizing that said accelerator frame is composed of a horizontal adjusting unit forcing the base moving to-and-fro horizontally, a vertical adjusting unit making a bent frame to move up and down vertically, a turn back adjusting unit letting a suspended arm rotate and an adjusting unit driving bending or lifting of the accelerator, a base, a vertical arm, a bend form and a suspended arm.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a fixed or combined mobile container detection system, which is suitable for the inspection of large and medium-sized container trucks in customs ports. Background technique [0002] The container cargo / vehicle inspection system is one of the inspection equipment that is urgently needed by customs ports. At present, the inspection of containerized goods in domestic and foreign ports mainly adopts the method of unpacking inspection or radiation imaging. It takes a long time to unpack and unpack the goods for inspection, the daily inspection volume is low, and the inspection cost is high. For radiation imaging, large-scale cargo / vehicle inspection systems using accelerators or cobalt-60 radiation sources have been developed at home and abroad, such as the large-scale cargo / vehicle inspection systems produced by German Heyman and British Aerospace Corporation. They are...
