Detailed Description

As shown in fig. 1-9, a portable linear array X-ray detection device comprises a guide rail 3, a slider 4, a synchronous belt 5, a slider connecting plate 7, a driven pulley 6, a driving pulley 15, and a driving motor 10. The slider connecting plate 7 is connected with the slider 4, the detection plates 8 are installed on the slider connecting plate 7, and all the detection plates 8 are aligned with each other and arranged in a linear array. The synchronous belt 5 is positioned below the slide block connecting plate 7 and is connected with the slide block connecting plate 7 through a connecting block 19. When the synchronous belt 5 rotates circularly, the slide block connecting plate 7 and the detection plate 8 can be driven to move leftwards or rightwards.

The rotation of the timing belt 5 is driven by a drive motor 10. The output shaft of the driving motor 10 is provided with a pinion 11, a driving belt wheel 15 is coaxially arranged with a gearwheel 13 through a connecting shaft 14, and the central holes of the pinion and the gearwheel are tightly matched with the connecting shaft 14 and can not rotate relatively. An idler gear 12 is arranged between the small gear 11 and the large gear 13, the small gear 11 is meshed with the idler gear 12, and the idler gear 12 is meshed with the large gear 13, and the number of teeth of the small gear 11 is less than that of the large gear 13. The pinion 11, the idler 12 and the bull gear 13 constitute a reduction system. After the output of the driving motor 10 is transmitted through the three gears, the speed is reduced to a required level, and the increased torque can drag sliding components such as the sliding connection plate 7, the detection plate 8 and the like.

In order to satisfy the portable requirement, the utility model discloses less thickness size has been controlled from the design angle. To achieve the purpose, the driven pulley 6 and the driving pulley 15 are in a flat state, that is, the axial directions of the driven pulley and the driving pulley are perpendicular to the plane on which the slider connecting plate 7 slides left and right. Accordingly, the drive motor 10 is a disk motor having a small thickness, and is arranged vertically, i.e., the direction of the output shaft thereof is parallel to the axial direction of the driving pulley 15. The driving motor 10, the pinion 11, the idler 12 and the bull gear 13 are connected as a whole by the driving base plate 9 and fixed on the housing 1.

The guide rail 3 and the slide block 4 are made of ultra-thin products, and the total height of the guide rail and the slide block after installation is 10 mm. The guide rail 3 is installed on the casing 1, controls the whole importance of lightening equipment, and the casing 1 material is the aluminum alloy. In addition, carbon fiber is selected as the material of the cover plate 2 because of its good strength and X-ray permeability. The cover plate 2 is connected with the shell 1 in a magnetic attraction mode. A step groove is formed in the housing 1, and a second magnet 17 is bonded in the step groove. Accordingly, the first magnet 16 is bonded to the cover plate 2, and the mating surfaces of the first magnet 16 and the second magnet 17 have opposite polarities. The shell 1 is provided with a handle 18 which is convenient to carry.

As shown in fig. 9, the specific working method of the present invention is: placing the present invention on one side of the suspect article 22 and placing the source of radiation 20 on the other side of the suspect article 22. The distance between the source 20 and the suspicious object 22 is properly adjusted to ensure that the radiation beam 21 can completely cover the suspicious object. The radiation beam 21 is cone-shaped. In the initial state, the slider connecting plate 7 and the detection plate 8 are located at the leftmost side or the rightmost side of the movement range. After the radiation source 20 and the device are turned on, the detection plate 8 moves from one side to the other side at a constant speed. In this process, the perspective image of the suspect article 22 may be transmitted to a computer of a remote operator for the operator to determine whether the suspect article 22 is safe.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention should be included in the scope of the present invention.
