Abstract
The utility model relates to a security inspection device with a double-lead-curtain structure. The security inspection device mainly comprises a casing, a channel arranged in the casing and a conveying belt penetrating the channel, wherein a plurality of X ray tubes arranged above the conveying belt and a detector arranged below the conveying belt are respectively arranged in the casing, and anti-radiation double-curtain shields are respectively arranged at an entrance and an exit of the channel. The double-curtain shields at the entrance and exit of the casing can effectively shield the X rays, and prevent the X rays from projecting out from the entrance, thereby greatly reducing the radiation of the security inspection device, and effectively protecting the safety and health of the operation personnel and passengers.
Description
Technical field
The utility model relates to a kind of X ray channel-type safety check apparatus, a kind of X ray channel-type safety inspection device with Ledate curtain structure of more specifically saying so.
Background technology
Along with the increase that subway is opened circuit, the public safety demand of subway increases year by year.Subway is carried out safety inspection become the necessary means that guarantees safety.Increasing rays safety detection apparatus is used to the security check of each subway.
The X-ray of screening machine possesses very strong penetration power, can run through the above homogeneous steel plate of 30mm usually at least.It x-ray dose that possesses is also just corresponding surprisingly big, under the control of international and domestic every safety standard, present equipment watchcase leaks ray usually only less than 0.2 μ Gry/h, for only passing through 2 times from rays safety detection apparatus every day, the passenger in each several seconds, this dosage is very little, does not generally think health is constituted injury.
But in real world applications, the passenger can stretch out one's hand usually bag is sent into the plumbous curtain of screening machine entrance owing to be eager by safety check, also is eager usually to take away and handle stretches into screening machine and exports plumbous curtain.In this process, the passenger will be subjected to the radiation of instantaneous super large dosage.Be example with Beijing, even if the probability that the passenger stretches out one's hand has only 0.01%, that just means has hundreds of people to be subjected to so instantaneous super large dosage radiation every day.
In peak period on and off duty, common a plurality of case and bag are crossed inspection simultaneously, continuous blow-down on travelling belt, cause plumbous curtain simultaneously to lopsidedness, opening, X-ray scattered ray in the exposure cell will have an opportunity to spill from the plumbous curtain of opening, and to the next door personnel, the safety check staff who aside works damages especially throughout the year.
The utility model content
The purpose of this utility model just provides a kind of safety check apparatus that can prevent above-mentioned situation.
The utility model solve the technical problem the technical scheme that adopts: a kind of safety check apparatus with Ledate curtain structure, it comprises casing, is arranged on the passage on the casing, the travelling belt of penetrating via, be respectively equipped with a plurality of x-ray pipes that are positioned at travelling belt top in the casing and be positioned at the detector of travelling belt below, it is characterized in that: all arrange at the entrance and exit of passage the two curtain covers of a radiation proof all are set.
The two curtain covers of described radiation proof comprise a case, are arranged on two plumbous curtains of the two curtain cover medial and lateral of radiation proof.Two-layer curtain can effectively reduce the probability that occurs the scattered ray leakage when plumbous curtain is started by case and bag.
The two curtain covers of described radiation proof are that removably is installed on the safety check apparatus, thereby make things convenient for its replacing.
Distance between the two plumbous curtains in the interior outside of the two curtain covers of described radiation proof is not less than adult little arm lengths, guarantees that the passenger can't reach hand the ray detection space.
Installation end at the two curtain covers of radiation proof arranges safe on-line switch, when this cover is bumped askew or installs when loosening, has any one safe on-line switch state to change, and the x-ray pipe namely is de-energized, and is that the crowded ray that causes of maloperation or passenger leaks thereby avoid the people.
Case mainly adopts 3 layers of composite structure, is respectively teflon, stereotype and steel plate from inside to outside, can connect by modes such as bonding or riveted joints.Teflon is the most inboard, with the case and bag friction.The polytetrafluoroethylene floor smooth surface, friction factor is little and nontoxic, can effectively avoid the wearing and tearing of self and passenger's case and bag, reduces the resistance that bulk transfer causes, and can prevent that toxic heavy metal lead is scratched throughout the year take out of in using; The suitable thickness stereotype can be kept out 90% above ray, prevents that the ray that enters space in the cover from spilling; Outside steel panel beating constitutes supporting construction.
3 layers of composite structure of the same employing of plumbous curtain, both sides are respectively teflon, traditional plumbous curtain is adopted at the center.Plumbous curtain like this is wear-resisting, nontoxic, attractive in appearance.
The beneficial effects of the utility model are: the double-deck curtain cover of casing gateway can effectively mask X ray, prevents that X ray from throwing away from the gateway, and the radiation of safety check apparatus is reduced greatly, has effectively protected operating personnel and passenger's safety and Health.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Shown in Fig. 1-4, a kind of safety check apparatus with Ledate curtain structure, it comprises casing 1, is arranged on the passage 2 on the casing, the travelling belt 3 of penetrating via, be respectively equipped with a plurality of x-ray pipes of being positioned at travelling belt 3 tops in the casing 1 and be positioned at the detector of travelling belt below, at the entrance and exit of passage 1 the two curtain covers 4 of a radiation proof are set all.
The two curtain covers 4 of described radiation proof comprise a case 5, be arranged on the safe on-line switch 7 that the two plumbous curtains 6 and of the two curtain cover medial and lateral of radiation proof arrange at the installation end of the two curtain covers of radiation proof.Described case 5 adopts 3 layers of composite structure, is respectively teflon 5.1, stereotype 5.2 and steel plate 5.3 from inside to outside, can connect by modes such as bonding or riveted joints.3 layers of composite structure of plumbous curtain 6 same employings, both sides are respectively teflon 6.1, traditional plumbous curtain 6.2 is adopted at the center.
Above-described embodiment is exemplary explanation principle of the present utility model and effect thereof only; and the embodiment of part utilization; to those skilled in the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
