Abstract
The utility model relates to a radiation-resistant television camera comprising an industrial grade solid camera. The utility model is characterized in that the utility model also comprises a radiation-resistant protective cover and a radiation-resistant camera lens; the radiation-resistant protective cover comprises an outer casing made of aluminum alloy material, a high-density lead layer covered on the inner surface of the housing, an innermost layer made of high-pure paraffin and an inner casing made of steel alloy. The solid camera and the zoom lens are arranged in the casing. The utility model has the advantages of easy production, low cost and long service life.
Description
The utility model relates to anti-irradiation apparatus, concrete relevant a kind of television camera of anti-irradiation.
The existing television equipment of using in the nuclear radiation environment generally all is to use the electron tube dedicated video camera, because of requiring each device wherein all to have radiation-resistant property, so manufacturing is difficult, cost is high, useful life is short, thereby is difficult to be extensive use of in the nuclear field.And general solid state camera has only tens hours useful life in radiation environment.
In view of the above problems, the purpose of this utility model provides the television camera of anti-irradiation of the low and long service life of a kind of cost.
For achieving the above object, the television camera of anti-irradiation of the present utility model comprises a technical grade solid video camera, is characterized in: also comprise an anti-radiation protection cover and anti-irradiation pick-up lens; Described anti-radiation protection cover comprises the outer casing made by aluminum alloy materials, cover high density lead layer on the described shell inner surface, be made of high paraffin refined wax an innermost layer and an inner housing; A described solid state camera and a zoom lens are arranged in the described inner housing.
Adopt the said structure scheme, owing to adopted anti-irradiation pick-up lens and anti-radiation protection cover, the useful life of having improved video camera greatly.Result on trial in nuclear power station shows can make video camera useful life up to more than 8700 hours.In irradiation station, use cumulative dose and can reach 2 * 10
6La Te (rad).
Specify the television camera of anti-irradiation of the utility model one embodiment below in conjunction with accompanying drawing, so that further understand the purpose of this utility model, characteristics and advantage.
Fig. 1 is the structural representation of the television camera of anti-irradiation of the utility model one preferred embodiment, has made biopsy cavity marker devices among the figure, to show its internal structure.
As shown in the figure, the television camera of anti-irradiation of the utility model one embodiment comprises a technical grade solid video camera 7, is characterized in: also comprise an anti-radiation protection cover and anti-irradiation pick-up lens 5; Described anti-radiation protection cover comprises the outer casing 1 made by aluminum alloy materials, cover high density lead layer 2 on described housing 1 inner surface, be made of high paraffin refined wax an innermost layer 3 and a steel alloy inner housing 4; A described solid state camera 7 and a zoom lens 6 are arranged in the described inner housing 4.On shell, do not have support 8, also be provided with cable outlet hole 9.Because described technical grade solid video camera is a prior art, and the structure of described anti-irradiation pick-up lens has disclosed in another utility application of the applicant in detail, so be not described further at this.
Adopt said structure to can be made into colored and the video camera of anti-irradiation black and white, through useful life that the result on trial at nuclear power station shows them up to more than 8700 hours.In irradiation station, use cumulative dose and reach 2 * 10
6La Te (rad).And owing to be that protective cover and pick-up lens adopt the nuclear radiation structure, other device all needn't require radiation-resistant property, therefore makes easy to manufacture, cost reduction.
