Abstract
The present invention discloses a guard gate structure for an anti-radiation shielding room, which relates to the technical field of radiation protection. The present invention comprises a guard gate and square shielding posts connected to the outlet of the wall of the shielding room, wherein one side end of the guard gate is hermetically jointed with one square shielding post; the other side end of the guard gate is provided with a boarding which can be hermetically jointed with the other square shielding post, or one side end of the guard gate is hermetically jointed with the square shielding post, and the other side end of the guard gate is provided with a turning wall connected with the wall of the shielding room shielded by the turning wall. Compared with the prior art, the present invention has the advantages that the guard gate is skillfully joint with the wall of the shielding room, direct leakage of the rays in the shield room to the outside can be effectively prevented, and the service life of the guard gate is simultaneously prolonged.
Description
Technical field
The present invention relates to the radiation protection technique field, especially between radiation-resistant labyrinth type shielding.
Background technology
At nuclear technology field, radioactive source or x-ray apparatus be at research, debugging and production period, is called between shielding for protection operating personnel and the public avoid the special factory building that the radiation infringement builds.In the prior art, as shown in Figure 1, generally all be to constitute between shielding by rectangle enclosure wall and protective door and labyrinth wall.In the actual construction between shielding because the influence of civil engineering deviation, generally all have between protective door and the barrier shield bigger slit (＞3cm).Cause the room inner rays to see through the safety zone of this clearance leakage beyond between shielding like this, thereby cause the dose of radiation level of regional area obviously to increase, to healthy and safe formation harm the personnel of this stop.In order to reduce the slit of body of wall between protective door and shielding, common way is that the artificial fitting allowance with enclosure wall between protective door and shielding is adjusted into negative common difference in the application.But in actual moving process, enclosure wall collision mutually, violent friction shorten dramatically the application life of protective door between the protective door of this structure and shielding.
Goal of the invention
At above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of protective door structure that is used between radiation-resistant glass.It can overlap enclosure wall between protective door and shielding dexterously, and ray interior between preventing from effectively to shield improves the application life of protective door simultaneously directly to external leakage.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes with following dual mode.
Technical scheme 1, a kind of protective door structure that is used between radiation-resistant glass, it comprises protective door.Its design feature is, it also comprise with shielding between the square shielding post that is connected of both sides, enclosure wall exit.One side of described protective door can be airtight involutory with a square shielding post, another side of protective door be provided with can with the airtight involutory coaming plate of another square shielding post lateral surface.
Compare with prior art, the present invention has carried out simple transformation to the structure of enclosure wall between protective door and shielding, the slit of ray between can preventing from effectively to shield by door and wall prevented the pollution of ray to surrounding environment and personnel to external leakage, ensured safety.The occupation of land space has been saved in labyrinth design in saving between former shielding simultaneously greatly.Consider the installation deviation of the manufacture deviation and the protective door of civil engineering deviation, protective door, even have the slit between protective door end and the square shielding post, ray is the slit in labyrinth through shape, must take place to arrive outside the protective door after the repeatedly scattering, to be weakened greatly through the ray that repeatedly scatters out, can be reduced by 10

4Doubly.In use avoid the sharp wear between enclosure wall between protective door and shielding in addition, improved protective door application life.
The present invention is further illustrated below in conjunction with accompanying drawing and concrete embodiment.
Description of drawings
Fig. 1 is for overlooking the cross section structure schematic diagram between prior art shielding;
Fig. 2 is for overlooking the cross section structure schematic diagram between the shielding of one embodiment of the present invention;
Fig. 3 is for overlooking the cross section structure schematic diagram between the shielding of another embodiment of the present invention.
The specific embodiment
Embodiment 1, referring to Fig. 2, and a kind of protective door structure that is used between radiation-resistant glass.It comprises protective door 1 with shielding between the square shielding post 2 that is connected of both sides, enclosure wall 3 exit.One side of protective door 1 can be airtight involutory with a square shielding post 2, another side of protective door 1 be provided with can with the airtight involutory coaming plate 4 of another square shielding post 2 lateral surfaces.
The present invention has in use solved well and has certain slit between the enclosure wall between protective door and shielding and bring between shielding inner rays directly to leak easily, causes the environmental radiation pollution problems.Experiment showed, that the ray through repeatedly scattering out will be weakened greatly, can reduce by 10
2～10
4Times, thereby the health and safety of effective support personnel and environment.
