Description

Station

Technical field

The disclosure relates generally to nuclear radiation monitoring field, more particularly to a kind of station.

Background technology

Nuclear radiation automatic monitor station is the automatic monitor station that an over all Integration manufactures and designs, and long-continued can be transported OK, and real-time, reliable radiation environmental monitoring data are obtained, is provided to grasp area radiation environmental quality and variation tendency The data of specialty.In nuclear emergency accident, nuclear radiation automatic monitor station can also carry out emergency monitoring, be carried for emergent Protective action decision For timely data.Usually main monitoring device is molten including high pressure ionization chamber (measurement gamma dose rate is horizontal), super-flow gas Glue sampling instrument (air aerosol monitoring), iodine sampler (iodine sample in air), meteorological measuring set (measurement meteorologic parameter), dry and wet Settle collector (fallout when collection precipitation and non-rainfall) etc..

In the measuring instrument of nuclear radiation automatic monitor station, high pressure ionization chamber is a kind of important part, for surveying The gamma dose rate measured in environment is horizontal, it is typically placed inside station, to prevent the influence of anomalous weather.It is each inside station Structure on direction is different, often causes the deviation of data accuracy.

And if make it that high pressure ionization chamber is contacted with outside air using structures such as shutters in station structure design, Though reducing gamma-emitting shielding, the air themperature of external world's change makes high pressure ionization chamber's instrument be influenced by temperature drift, extreme influence The stability and accuracy of data.

Utility model content

In view of drawbacks described above of the prior art or deficiency, it is intended to provide that a kind of detection data are accurate, stablize and by station Influence small station.

In a first aspect, the application provides a kind of station, the guarantor for accommodating detecting instrument is provided with the top of the station Temperature cover, the cavity of the insulation cover are communicated by being arranged on the opening at the top of station with the space in the station；The insulation The uniform wall thickness of cover.

The uniform wall thickness of insulation cover ensure that insulation cover is consistent to the shield effectiveness of all directions ray.

According to technical solution provided by the embodiments of the present application, the horizontal cross-section of the insulation cover is rounded.Circular level Section further such that detecting instrument survey the external world horizontal plane all directions radiation effect it is consistent.

According to technical solution provided by the embodiments of the present application, the top of the insulation cover is hemispherical, and its underpart is cylinder Shape.

According to technical solution provided by the embodiments of the present application, lifting is installed below detecting instrument in the station Instrument, the lifting instrument are used to the detecting instrument being placed in the insulation cover.

Above-mentioned station that the application provides is either a station in small-sized monitoring station or large-scale monitoring station Room.

In conclusion the beneficial effect of the application is：The station of the application causes detecting instrument to be maintained at stable temperature Work in environment, ensure that the stability of testing result；Protrude from the insulation cover outside station and effectively reduce station shell structure Influence to detecting instrument；Improve the stability and accuracy of detecting instrument numerical measuring.

Embodiment

The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that in order to It illustrate only easy to describe, in attached drawing with inventing relevant part.

It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase Mutually combination.Describe the application in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Please refer to Fig.1 the application and a kind of structure diagram of station is provided, the top of the station 10 is provided with for holding Receive the insulation cover 20 of detecting instrument 30, the cavity of the insulation cover 20 passes through the opening for being arranged on the top of station 10 and the station Space in 10 communicates；The uniform wall thickness of the insulation cover 20.In one embodiment, the insulation cover 20 and the station 10 1 Body shapes, and the insulation cover 20 is outstanding formed by the top of station 10；In another embodiment, the insulation cover 20 and institute State station 10 independently, the top of the station 10 is provided with opening, and the insulation cover 20 covers over said opening.Protrude from The measurement that 20 structure of insulation cover at the top of station 10 avoids detecting instrument 30 is influenced be subject to 10 internal structure of station.It is real one Apply in example, detecting instrument 30 is the high pressure ionization chamber for detecting the gamma dose rate level in 10 external environment condition of station；Another In embodiment, detecting instrument 10 is the gamma ray spectrometer of the gamma dose rate level in 10 external environment condition of station, in other embodiments, inspection It can be gamma ray probe to survey instrument 30.

In a preferred embodiment, the insulation cover is made of glass fibre, in another embodiment, the insulation cover by Plastics are made；In other embodiments, the insulation cover is made of other light materials weaker to gamma-ray shielding action.

In above-described embodiment, the thickness of insulation cover can be set according to user's measurement demand, and the wall thickness of insulation cover is smaller, its It is smaller to gamma-ray shielding.

In a preferred embodiment, the horizontal cross-section of the insulation cover 20 is rounded, in same section, detecting instrument 30 away from Equal with a distance from the inner wall of insulation cover 20, detecting instrument 30 is surveyed extraneous all directions radiation level influences unanimously.Implement one In example, the top of the insulation cover 20 is hemispherical, and its underpart is cylindric；In another embodiment, the insulation cover 20 is 3/4ths spherical shapes.

In one embodiment, lifting instrument 40, detecting instrument 30 are installed in the station 10 in the lower section of detecting instrument 30 Rise fixed placement in insulation cover 20 by lifting instrument 40；In another embodiment, detecting instrument 30 directly passes through station 10 Interior fixed platform is fixed in insulation cover 20.

Above description is only the preferred embodiment of the application and the explanation to institute's application technology principle.People in the art Member should be appreciated that invention scope involved in the application, however it is not limited to the technology that the particular combination of above-mentioned technical characteristic forms Scheme, while should also cover in the case where not departing from the inventive concept, carried out by above-mentioned technical characteristic or its equivalent feature The other technical solutions for being combined and being formed.Such as features described above and (but not limited to) disclosed herein have it is similar The technical solution that the technical characteristic of function is replaced mutually and formed.
