A channel type x-ray security inspection device

Abstract

The invention discloses a channel type X-ray security inspection device. The device comprises a base and an X security inspection machine; a conveying device is arranged in the base; a conveying device comprises a rotatable conveying belt; the conveying belt is used for driving packages to be conveyed from right to left; opening and closing devices are arranged on the front side and the rear sideof the conveying belt; each opening and closing device comprises rotatable opening and closing rotating rods; the distance between each pair of opening and closing rotating rods can be adjusted according to the size of a package. In applications, a package conveyed from right to left is scanned by X-rays; an X-ray perspective image is formed on an X-ray detection box for security check; the X-rayirradiation range and the X-ray dose can be adjusted; the X-ray irradiation range is designed to be synchronous with the opening and closing devices, so that the size of an input package can match theX-ray irradiation range, the security check is comprehensive, the leakage of X-rays is reduced, the radiation is reduced; and in addition, the adjustment of the X-ray dosage can be adjusted accordingto packages with different penetration rates, the security check effect is improved, and the radiation is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of security inspection, in particular to a channel-type X-ray security inspection device. Background technique [0002] The cargo or package security inspection at the station usually uses the X-rays emitted by the security inspection equipment to penetrate the package, and then form an X-ray perspective view on the X-ray detection box to detect dangerous items in the package, but X-rays have certain radiation. Although there are lead curtains installed at both ends of the security inspection machine, the input and output of the package will cause the lead curtain to be opened, and the X-rays will leak out. In-depth security checks are carried out for multi-layered and difficult-to-detect packages. At this time, the radiation is the largest, and small-volume or X-ray-penetrating packages increase the leakage of radiation during security checks. The present invention illustrates a device capable of solving t...

[0002] The cargo or package security inspection at the station usually uses the X-rays emitted by the security inspection equipment to penetrate the package, and then form an X-ray perspective view on the X-ray detection box to detect dangerous items in the package, but X-rays have certain radiation. Although there are lead curtains installed at both ends of the security inspection machine, the input and output of the package will cause the lead curtain to be opened and the X-rays will leak out. In order to improve the X-ray irradiation effect, the X-ray dose is usually fixed and the maximum, so that In-depth security checks are carried out for multi-layered and difficult-to-detect packages. At this time, the radiation is the largest, and small-volume or X-rays are easy to penetrate during security checks, increasing radiation leakage.
