摘要:
An arm-folding mechanism for use in a vehicle-mounted radiation imaging system. The vehicle includes a vehicle body behind a driving cab. The vehicle body includes a generator cabin and a control cabin. The arm-folding mechanism includes a vertical detection arm, a main arm frame, and a hinged mechanism hingedly connecting the vertical detection arm with the main arm frame. The hinged mechanism includes: a first connection arrangement having a free end and a fixed end fixedly connected with or integral with the main arm frame; a second connection arrangement fixedly connected with the vertical detection arm; and an intermediate arrangement connecting the first connection arrangement with the second connection arrangement so that the vertical detection arm can rotate relative to the main arm frame. The bottom of the first connection arrangement is at the same level as or above the bottom of the main arm frame.

摘要:
A device for inspecting contraband in an aviation cargo container includes: a turntable and a scanning system, the scanning system including a radiation source; a detector; a radiation source mounting structure; and a detector mounting structure for mounting the detector. Each of said radiation source mounting structure and said detector mounting structure includes at least one column assembly. The radiation source and the detector are mounted on the column assembly and allowed to synchronously ascend and descend along said column assembly. By combining different movement modes of the turntable and the scanning system, the device of the present invention can scan the object in various scanning modes. The device is stable in structure, convenient in installation, and occupies a small space. The device can inspect aviation containers over two meters long and/or over two meters wide and achieve a relatively high passing rate of the objects.

A device for inspecting contraband in an aviation cargo containers includes: a turntable located at an object inspecting position and configured to carry the object to be inspected and bring the object into rotation; an object conveying system; a scanning system including a radiation source and a detector which can synchronously move in the vertical direction; a turntable drive/control system which drives and controls rotation of said turntable so that the turntable can continuously rotate about its rotation axis or rotate to any predetermined angular position; a scanning drive/control system which drives and controls the radiation source and the detector into synchronous movement in the vertical direction so that the radiation source and the detector can continuously move in the vertical direction or move to any predetermined vertical position. The device of the present invention can scan the object and form images in various scanning modes to meet different needs.
摘要:
The present invention discloses a security inspection door comprising a narcotic drug/explosive detecting subsystem, a radioactive substance detecting subsystem and a metal detecting subsystem which are provided in a tank body, wherein electromagnetic radiation shields are respectively provided around the three detecting subsystems, so that the narcotic drug/explosive detecting subsystem, the radioactive substance detecting subsystem and the metal detecting subsystem are isolated from one another and are not interfered with one another. In the present invention, the narcotic drug/explosive detecting subsystem, the radioactive substance detecting subsystem and the metal detecting subsystem are combined together for the first time to form a novel security inspection door, so the narcotic drugs/the explosives, the radioactive substances and the dangerous metal articles can be detected at the same time. Further, in the present invention, electromagnetic radiation shields are respectively provided around the three detecting subsystems, so that the three detecting subsystems are isolated from one another and are not interfered with one another, and thus, the inspection reliability and the inspection accuracy are improved.
