Description

Technical Field

[0001] The present invention belongs to the field of core CT scanning imaging detection, and in particular relates to a shipborne full-core CT scanning imaging detection device. Background Art

[0002] With the increasing scarcity of land and shallow sea resources, the development and utilization of marine resources have increasingly become the focus of attention of various countries. To accelerate the exploration and development of deep-sea resources, it is necessary to build a special drilling ship for ocean science. At the same time, in order to obtain data of underwater cores in a timely manner, a CT scanning imaging detection device needs to be installed on the drilling ship. In the existing technology, the hull on the sea surface shakes severely, and the CT scanning imaging detection device is affected by this, resulting in data deviation. Moreover, in dangerous waters, it is easy to pose a safety hazard to the equipment and affect CT imaging. At the same time, the anti-radiation isolation device of the existing single-body CT scanning imaging detection device is simple. If care is not taken during the detection process, there is a risk of radiation leakage, presenting a safety hazard. At the same time, the transmission component of CT detection is usually a manipulator device, which has a high construction cost, occupies a large space, has a high maintenance cost, is not easy to operate and install, and is especially prone to damage after being impacted at sea.
