[0041] The utility model provides a safety protection cabinet for nuclide subpackaging and purification.

[0042] A safety protection cabinet for nuclide subpackaging and purification, comprising: an outer box body 1, the front side panel of the outer box body 1 is provided with a first through hole 111; an inner liner 2, the interior of the inner liner 2 is an operating room 21, the front side panel of the inner liner 2 is provided with a second through hole 22; a lead brick wall 3, the lead brick wall 3 is laid on the outer side of the inner liner 2, the outer box body 1 and the inner liner 2 are separated by the lead brick wall 3, the front side wall of the lead brick wall 3 is provided with a third through hole (not shown), the first through hole 111, the second through hole 22 and the third through hole are provided. The central axes coincide with each other; the manipulator structure 4 includes a sword-type manipulator (not shown) and a lead ball 45. The sword-type manipulator includes a handle 41, a telescopic rod 42, and a gripping member 46. The lead ball 45 is fixed to the telescopic rod 42. The telescopic rod 42 passes through the first through hole 111, the third through hole, and the second through hole 22 in sequence. The lead ball 45 is sealed and rotatably connected to the third through hole. The handle 41 is provided on the outside of the outer box 1, and the gripping member 46 is provided on the inside of the inner liner 2. The sword-type manipulator itself is prior art, and its specific structure and working principle will not be described in detail here.

[0043] In the technical solution proposed in the present application, when taking the sub-packaged medicine bottles, the handle 41 of the sword-type manipulator is operated, and the grasping part 46 of the sword-type manipulator can take the sub-packaged medicine bottles, which is very convenient; the handle 41 is arranged on the outside of the outer box body 1, and the operator does not need to put his hand deep into the operating room 21 to take the medicine bottle, which improves the radiation protection ability of the utility model; the lead ball 45 has an anti-radiation function, and the lead ball 45 cooperates with the third through hole to ensure that the telescopic rod 42 of the sword-type manipulator can rotate normally, while also preventing electromagnetic waves from leaking through the third through hole.

[0044] The manipulator structure 4 also includes a lead ball blocking ring 43. The lead ball blocking ring 43 is in the shape of a truncated cone. The central axis of the lead ball blocking ring 43 coincides with the central axis of the third through hole. The large diameter end of the lead ball blocking ring 43 is sealed and fixedly matched with the first through hole 111. The small diameter end of the lead ball blocking ring 43 is located between the outer box 1 and the lead brick wall 3. A spherical groove (not shown) is provided on the outside of the third through hole. One end of the lead ball 45 rotates with the spherical groove, and the other end of the lead ball 45 contacts and cooperates with the inner ring of the small diameter end of the lead ball blocking ring 43. The rotational cooperation between the lead ball 45 and the spherical groove allows the lead ball 45 to rotate freely relative to the third through hole. The lead ball blocking ring 43 performs the following functions: shielding the lead ball 45, thereby ensuring the aesthetics of the present invention; limiting the rotation range of the sword-shaped manipulator; and preventing the lead ball 45 from detaching from the spherical groove.

[0045] The manipulator structure 4 also includes a lead ball retaining ring 44. The outer circumference of the lead ball retaining ring 44 is sealed and fixedly connected to the end of the third through hole away from the inner liner 2. The inner circumference of the lead ball retaining ring 44 is engaged with the lead ball 45. Because the thickness of the lead ball 45 decreases as it approaches the side of the third through hole, its radiation protection capability decreases. The provision of the lead ball retaining ring 44 precisely compensates for this shortcoming, thereby further enhancing the radiation protection capability of the present invention. Furthermore, the lead ball retaining ring 44 further prevents the lead ball 45 from detaching from the spherical groove.

[0046] The safety protection cabinet for radionuclide packaging and purification also includes an air intake and exhaust system 5, which includes: an air intake fan hood 51, which is arranged on the outside of the top plate of the inner liner 2, the bottom of the air intake fan hood 51 is connected to the interior of the inner liner 2, and the top of the air intake fan hood 51 is connected to the outside of the outer box body 1; an air intake fan (not shown in the figure), which is installed in the air intake fan hood 51; air exhaust ports 52, on the bottom plate of the inner liner 2, a plurality of air exhaust ports 52 are arranged in a matrix at opposite ends along its width direction; an exhaust channel 53, the exhaust channel 53 is installed on the outside of the bottom plate of the inner liner 2, and all the air exhaust ports 52 on the bottom plate of the inner liner 2 are respectively connected to the interior of the exhaust channel 53; an exhaust pipe 54, one end of the exhaust pipe 54 is connected to the side of the exhaust channel 53 and is connected to the interior of the exhaust channel 53, and the other end of the exhaust pipe 54 is arranged on the outside of the outer box body 1 and is connected to the exhaust fan 56.

[0047] When the air intake and exhaust system 5 is in use, the air intake fan 56 sends external air into the interior of the inner liner 2. Under the action of the exhaust fan 56, the gas in the inner liner 2 is first discharged into the exhaust channel 53 through the exhaust port 52 on the bottom plate thereof, and then discharged into the exhaust pipe 54 through the exhaust channel 53, and then filtered by the filter 55, and finally discharged to the outside through the exhaust fan 56. By setting the air intake fan and the exhaust fan 56 to control the gas flow direction, the air pressure and cleanliness state of the operating room 21 can be maintained at a relatively stable state that meets the requirements.

[0048] The front side panel of the outer box 1 is provided with a protective door 12 and a manipulator mounting plate 11. The manipulator mounting plate 11 is provided on one side of the protective door 12. A first through hole 111 is provided on the manipulator mounting plate 11. A first observation window 13 is provided on the protective door 12. A second observation window 14 is provided on the manipulator mounting plate 11. The second observation window 14 is provided directly above the first through hole 111. The provision of the second observation window 14 facilitates observation of the operation of the gripping member 46.

[0049] Below the operating room is a storage compartment containing a lead barrel and a lifting platform for raising and lowering the barrel. The barrel houses an activity meter, and the bottom plate of inner liner 2 has a through-hole corresponding to the barrel. The bottom plate of inner liner 2 also has a waste hole connected to the storage compartment. The storage compartment also houses a waste bucket, which is connected to the waste hole. The content described here can be referenced with the Chinese utility model patent, entitled "A Radionuclide Dispensing Cabinet," with authorization number CN214336352U. Its specific structure and operating principle will not be elaborated upon here, nor will the relevant structures be labeled.

[0050] The outer side of the top plate of the inner liner 2 is paved with top lead bricks (not shown), the outer side of the bottom plate of the inner liner 2 is paved with bottom lead bricks (not shown), and the exhaust fan 56 is installed on the outer side of the top lead bricks.

[0051] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
