The specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. In addition, it should be noted that, for convenience of description, only a part of structures related to the present invention, not all of the structures, are shown in the drawings.
Referring to fig. 1, which is a schematic structural diagram of a radiation-proof security inspection device according to an embodiment of the present invention,
A radiation-proof security inspection device comprises a security inspection case 1 and a conveyor belt 2, wherein the conveyor belt 2 is located on the lower surface of the security inspection case 1 and used for conveying articles to be detected into the security inspection case, and a hollow cavity is defined by the security inspection case and the conveyor belt and used for placing the articles to be detected; be provided with two curved surface baffles 3 respectively in security installations machine case 1 entry and export both sides, install ray shield door 4 between two curved surface baffles 3, ray shield door 4 includes fixed axle 41 and a plurality of revolving door 42, and a plurality of revolving doors are transmission dress fixed mounting on the fixed axle, when rotating around the fixed axle, wait to detect the space of article between two revolving doors along with the rotation of ray shield door, enter into the security installations by the removal of conveyer belt 2 in, form an airtight space between security installations machine case 1, ray shield door 4 and the curved surface baffle 3 all the time.
Specifically, the baggage is placed on the conveyor belt 2, the baggage enters the entrance of the radiation shielding door 4 along with the movement of the conveyor belt 2, the rotating direction of the rotating door 42 is consistent with the moving direction of the conveyor belt 2, that is, when the conveyor belt 2 moves from the south to the north, the rotating door 42 rotates counterclockwise, and the rotating speed of the rotating door 42 is slower than the moving speed of the conveyor belt 2, so that the baggage can timely move out of the radiation shielding door 4 from the exit to enter the security inspection cabinet 1 when the baggage moves to the exit of the radiation shielding door 4; if the conveyor belt 2 moves from the north to the south direction, the revolving door 42 rotates clockwise, and the revolving door 42 rotates slower than the moving speed of the conveyor belt 2.
because ray shield door 4 comprises a plurality of revolving doors 42, and a plurality of mutual certain angles that become between the revolving door, no matter the revolving door rotates to any angle, security check machine case and revolving door 42 form a confined space all the time, prevent that the ray in security check machine case 1 from taking place to leak.
In this embodiment, 2 curved surface baffles are symmetrically arranged on both sides of the inlet of the security inspection machine case 1, 2 curved surface baffles are symmetrically arranged on both sides of the outlet of the security inspection machine case 1, in order to enable the edge of the side surface to contact with the curved surface baffle 3 in the rotating process of the revolving door 42, the side surface is tightly combined with the curved surface baffle to prevent the ray from leaking, the curved surface baffle uses the center of a circle of the fixed shaft, the width of one revolving door is a curved surface formed by the radius, and the height of the curved surface baffle is flush with the height of the security inspection machine case.
Furthermore, two curved surface baffles at the inlet of the security inspection case 1 enclose a channel, the inlet of the channel is the inlet of a first ray shielding door along the moving direction of the conveyor belt, the outlet of the channel is the outlet of the first ray shielding door, and the outlet of the first ray shielding door is communicated with the inlet of the security inspection case; the two curved surface baffles at the outlet of the security inspection case enclose a channel, the inlet of the channel is the inlet of a second ray shielding door along the moving direction of the conveyor belt, the outlet of the channel is the outlet of the second ray shielding door, and the inlet of the second ray shielding door is communicated with the outlet of the security inspection case; in order to maximize the space available for baggage to pass through, the entrance and exit of the radiation screen door 4 is the same width as the aisle of the security cage 1.
Furthermore, the included angles between the plurality of revolving doors 42 are equal, and the maximum distance between two adjacent revolving doors is equal to or greater than the entrance width of the ray shielding door 4. When the outlet of the ray shielding door 4 is completely positioned between two adjacent revolving doors, a closed space can be formed between the ray shielding door and the security inspection case. The entrance width and the exit width of the radiation shielded door 4 are equal.
When the revolving door only has two, the contained angle between two revolving doors is 180 degrees, when the revolving door rotates to be parallel with the direction of motion of conveyer belt, ray shield door's import and export communicate completely, can't shield the ray. When the revolving door is 3, the included angle between two adjacent revolving doors is 120 degrees, and the maximum distance between two adjacent revolving doors is equal to or greater than the entrance width of the ray shielding door 4, no matter the revolving door rotates to any angle, the revolving door can form a closed space with the security inspection case 1. Therefore, the revolving door is provided with 3 leaves and more.
