Embodiment Construction

[0025] The ship radiation imaging detection device proposed by the present invention needs to rely on the common 'ship lifting device' of the port. This type of device is a large movable lifting frame, as shown in Figure 1. The device lifts the ship from the water surface with a sling, and then transports it to a certain site for maintenance by means of a traveling mechanism. This is common equipment in port areas, and there are stereotyped products available in the market, such as ASCOM's LBS product series.

[0026] The 'ship radiation imaging detection system' proposed by the present invention consists of a gamma-ray source placed in a shielded container, a gamma-ray array detector, a detector pre-circuit, a signal acquisition and processing device, and an electromechanical system. The main feature of the present invention is that several rails are installed on the ship lifting device, the direction of the rails is consistent with the length direction of the ship, and the ...

Abstract

The present invention provides a ship radiation imaging and detecting system, which belongs to the field of nucleus technology application. The present invention is characterized in that: a Gamma ray source and a Gamma ray array detector are arranged on a railway which is fixed on a ship handing equipment and can simultaneously skid along the railway. The railway is parallel with ground and extends along the direction of the length of the ship. The radiation field of the Gamma ray source can cover the cross section of a ship body in the width direction. The Gamma ray array detector can receive the Gamma ray passing through the ship body. A detector pre-circuit gathers detecting input signals and processes with a processing device. The present invention can obtain a ship radiation perspective image and a good penetrating effect. The present invention has the advantages of economy, practicality and flexibility and so on; in addition, the present invention has good market value and can acquire very good social profit.

Description

Technical field: [0001] The invention belongs to the application field of nuclear technology, in particular to gamma radiation imaging detection technology for ships. It uses gamma radioactive isotope ray sources, array detectors, etc., and relies on the "ship lifting device" commonly used in ports to scan and obtain radiographic images of the ship's hull, so as to inspect the ship and its cargo. Background technique: [0002] Nowadays, most of the offshore or river transportation in many regions (such as the Middle East) is completed by small and medium-sized ships. The actual survey of Dubai Port shows that the local ships are mainly of wooden structure, among which the size of small wooden ships is about 24m (length) × 8m (width), while the size of medium-sized wooden ships is about 45m (length) × 13m (width) . Relevant management departments point out that at present a large number of smuggling and smuggling of illegal substances (such as weapons and drugs) rely on suc...
