Abstract
The invention discloses an installation device for a radioactive source and belongs to the field of radioactive source application. The installation device comprises a stator, a rotor and a collimator, wherein the rotor and the collimator are respectively installed on the two ends of the stator; the rotor and the collimator are partitioned by an internal partition plate in the stator; a groove is formed on the end face, contacted with the partition plate, of the rotor, and the radioactive source is installed in the groove. The device provided by the invention utilizes an eccentric mechanism to ensure that the axis of the rotor and the collimating aperture axis of the collimator are misaligned; and meanwhile, the radioactive source is installed on the rotor and the installation position of the radioactive source is not on the central axis of the rotor, thus the rotor can perform rotary motion relative to the stator. When the centre of the radioactive source is exactly located at the collimating aperture axis of the collimator, the radioactive source is at a working position and rays can be ejected through the collimating aperture of the collimator; when the centre of the radioactive source deviates from the collimating aperture axis of the collimator, the radioactive source is at a storage position and the rays emitted from the radioactive source can be sheltered by the collimator; the switch between the working position and the storage position can be conveniently realized by rotating the rotor or the collimator; and four sides of the radioactive source at the storage position are all provided with shielding materials, thus the effective shielding for the radioactive source at the storage position can be ensured.

Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Fig. 1 shows the radioactive source erecting device structural representation of the embodiment of the invention, and it comprises: stator 1 is installed in the rotor 2 and the collimating apparatus 8 at stator 1 two ends respectively.Rotor 2 and collimating apparatus 8 are separated by stator 1 internal partition 10, and dividing plate 10 is arranged between the mounting groove (figure does not indicate) of described rotor 2 and collimating apparatus 8, dividing plate 10 preferred and stator 1 integral type making.Offer groove 11 on rotor 2 and the end face that dividing plate 10 contacts, radioactive source is installed in the groove 11, and groove 11 can be adjusted its size and shape according to the geometric properties of the radioactive source that wherein will place.In order to realize effective shielding of radioactive source, rotor 2 outsides, promptly its end away from collimating apparatus 8 is provided with rotor cover plate 6, and stator 1 outer setting has stator cover plate 5.Active cover plate 3 is set between groove 11 and the dividing plate 10, the outside of collimating apparatus 8, promptly its end away from rotor 2 is provided with collimating apparatus cover plate 9, to realize the protection of collimation device 8.Be connected to static connection between source cover plate 3 and the rotor 2, static connection is any type of removably connecting, similar connection also has being connected of stator 1 and stator cover plate 5, rotor cover plate 6 is connected with stator cover plate 5, collimating apparatus cover plate 9 is connected with stator 1, preferred connected mode is the screw connection and is threaded in the present embodiment, for example shown in the figure, adopt first attachment screw 4 that source cover plate 3 is installed on the rotor 2, use second attachment screw 7 that stator cover plate 5 is installed on the stator 1, between rotor cover plate 6 and the stator cover plate 5 by being threaded.Adopt revolute pair to be connected between rotor 2 and the stator 1, guarantee that rotor 2 can rotate with respect to stator 1, it can be any type of revolute pair that revolute pair connects, and preferred employing is slidingly connected in the present embodiment.
In order to realize the effective switching of radioactive source between working position and storage position, the central shaft of the central shaft of stator 1 and rotor 2 is set to not conllinear.Simultaneously, when keeping collimating apparatus 8 motionless, the central shaft that the central shaft of groove 11 and rotor 2 be set is conllinear not; Central shaft end points with rotor 2 is that the center of circle, this center of circle are that radius forms circle to the distance of groove 11 central shafts, and the central shaft of collimating apparatus 8 collimating apertures (not indicating among the figure) is the tangent line of this circle.At this moment, on rotor 2, handle is set, drives rotor 2 by the manpower turning handle and rotate; Perhaps, on rotor 2, shaft coupling is set, connects external power supply by shaft coupling and rotate to drive rotor 2.If collimating apparatus 8 materials are identical with stator 1 material, can make collimating apparatus 8 and stator 1 be processed into one so, promptly cancel independently collimator structure and collimating apparatus cover plate.
The set-up mode of above-mentioned eccentric mechanism also can be replaced by, and the central shaft that the central shaft of collimating apparatus 8 collimating apertures and collimating apparatus 8 outer cylinders are set is conllinear not, and the central shaft that guarantees groove 11 central shafts and collimating apparatus 8 outer cylinders simultaneously is conllinear not; Central shaft end points with collimating apparatus 8 outer cylinders is that the center of circle, this center of circle are that radius forms circle to the distance of the central shaft of collimating apparatus 8 collimating apertures, and the central axis of groove 11 is the tangent line of this circle.At this moment, on collimating apparatus 8, handle is set, drives collimating apparatus 8 by the manpower turning handle and rotate; Perhaps, on collimating apparatus 8, shaft coupling is set, connects external power supply by shaft coupling and rotate to drive collimating apparatus 8.
Above-mentioned radioactive source erecting device is laterally to place, and can as required this device be done as a whole vertical placement in actual the enforcement, perhaps tilts to place arbitrarily.
Keep motionless with collimating apparatus 8, rotor 2 is rotated and is example, and the principle of work of radioactive source erecting device is: utilize eccentric mechanism, rotor 2 rotation center axis are not overlapped with stator 1 central axis; Simultaneously, radioactive source is installed in the groove 11 of rotor 2, the radioactive source installation site not on rotor 2 central axis, i.e. the central axis of the central axis of groove 11 and rotor 2 conllinear not, rotor 2 can be done gyration with respect to stator 1.In rotor 2 rotary courses, the radioactive source center is just on collimating apparatus 8 collimating aperture central shafts the time, and ray just can penetrate by collimating aperture.When rotor 2 continues rotation, make radioactive source misalignment collimating apparatus 8 collimating aperture central shaft certain distances when (this distance is decided by the physical dimension of radioactive source), the ray that radioactive source sends blocks collimated device 8.Usually, the radioactive source center just the position when collimating apparatus 8 collimating aperture central shafts be working position (seeing position shown in the accompanying drawing 1); When radioactive source departed from this position, just for storing the position, rotor realized that working position is very convenient with the switching of storing interdigit.By rational design, among radioactive source four sides, place, storage position all can be in the parcel of thicker structure material and shielding material, can realize effective shielding to ray.
