Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A shielding container for intermediate- to high-level radioactive waste includes an outer container 1, a sealing cap 2, a shielding layer 3, and an inner container 4. The sealing cap 2 is attached to the surface of the outer container 1. The inner container 4 is sleeved with the shielding layer 3, and the shielding layer 3 is welded to the outer container 1. A filling layer 5 is filled between the shielding layer 3 and the inner container 4. A connecting plug 21 is fixedly connected to the surface of the sealing cap 2, and the connecting plug 21 is inserted into the inner container 4. A connecting disc 6 is fixedly connected to the inner wall of the shielding layer 3. A hook 7 is fixedly connected to the outer surface of the outer container 1.

The inner surface of the sealing cap 4 is fixedly connected to the connecting plug 42, and the inner surface of the connecting plug 42 is fixedly connected to the connecting post 42. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 42, and the inner surface of the connecting plug 42 and the connecting post 42 are connected to the connecting post 42. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 42 and the connecting post 6. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 42 and the connecting post 6. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 43 and the connecting post 42. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 43 and the connecting post 42. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 43 and the connecting post 42. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 43 and the connecting post 42. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 43. The inner surface of the sealing cap 4 is fixedly connected to the connecting post 42 ...

[0024] Furthermore, a rubber gasket is fitted onto the outer surface of the connecting plug 21, and the rubber gasket abuts against the inner wall of the inner container 4 through the sealing cap 2 and the connecting plug 21. The outer container 1, the shielding layer 3, and the inner container 4 are connected sequentially from the outside to the inside. Through the connection of the connecting plug 21 and the rubber gasket, the sealing performance and effect of the sealing cap 2 on the inner container 4 are improved under the abutting contact between the rubber gasket and the inner container 4.

[0025] Furthermore, the filling layer 5 is composed of a material with buffering and heat insulation properties. The inner wall of the shielding layer 3 and the outer surface of the inner container 4 are in contact. Through the function of the filling layer 5, the buffering and heat insulation effects between the inner container 4 and the shielding layer 3 are achieved. As for the specific material of the filling layer 5, it is not limited here, but is determined according to the radioactive waste to be placed. Its main function is to achieve the buffering and heat insulation effects. The contact between the shielding layer 3 and the inner container 4 facilitates the dissipation of heat inside the inner container 4 by the shielding layer 3.

[0026] Furthermore, the connecting handles 41 are arranged in two opposing groups on the surface of the inner container 4. The connecting post 42 is elastically slidably connected to the inner container 4 through the support spring 45 and the storage groove 44. The inner container 4 is connected to the connecting handles 41. Under the action of the connecting handles 41, it is convenient to lift the inner container 4 in the shielding layer 3, thereby facilitating the disassembly, assembly and maintenance of the inner container 4 in the shielding layer 3.

[0027] Furthermore, the size of the connecting groove 47 is larger than the size of the card plate 43. The card plates 43 are arranged in two opposing groups on both sides of the connecting post 42. The outer surface of the connecting post 42 is fixedly connected to a sliding plate, and the sliding plate and the limiting groove 46 are slidably connected. Through the connection of the connecting post 42 and the card plate 43, and with the connection of the support spring 45 and the storage groove 44, it is convenient to fit the connecting post 42 and the card plate 43 on the inner container 4, without affecting the normal placement operation of the inner container 4 on the plane.

[0028] Furthermore, the card plate 43 and the slot 61 are slidably connected. The slots 61 are arranged in two opposing sets on the surface of the connecting plate 6. The cross-section of the card groove 62 is circular. The card plate 43 is connected by rotating the slots 61 and the card groove 62. Through the insertion of the connecting post 42 and the connecting plate 6, the card plate 43 and the card groove 62 are connected by the slots 61 and the card groove 62, thereby achieving the connection, positioning and support effect of the inner container 4 in the shielding layer 3. Rotating the inner container 4 changes the action of the card plate 43, thereby achieving its quick disassembly and assembly operation performance.

[0029] Furthermore, a circular groove is formed on the surface of the sealing cap 2, and the screw 8 passes through the circular groove and is connected to the screw sleeve 9. The sealing cap 2 and the outer container 1 are connected by the screw 8 and the screw sleeve 9. A sealing gasket is provided on the surface of the sealing cap 2 that contacts the outer container 1. With the connection of the screw 8 and the screw sleeve 9, it is convenient to support the installation of the sealing cap 2 on the outer container 1. Under the action of the sealing gasket on the sealing cap 2, the sealing performance of the sealing cap 2 when installed and used on the outer container 1 is further improved.

[0030] Working principle: When processing intermediate and high-level radioactive waste, the waste is placed into the inner container 4. The sealing cover 2 is then closed by the action of the screw 8 and the screw sleeve 9. After that, sealant is applied to the joint between the sealing cover 2 and the outer container 1 to complete the seal. Then, by setting up corresponding detection sensors and using wireless sensor network technology, the shielded container can be remotely monitored and controlled. When disassembling or repairing the inner container 4, the connecting handle 41 is rotated to make the connecting handle 41 vertical, which facilitates the operation of the inner container 4. Rotating the inner container 4 changes the position of the card plate 43 in the card slot 62. When the card plate 43 and the slot 61 are aligned, the inner container 4 is pulled by the connecting handle 41. At this time, the inner container 4 and the shielding layer 3 are separated. When placing the inner container 4, under the action of the support spring 45 and the storage groove 44, the connecting post 42 is embedded in the bottom of the inner container 4, which does not affect the normal placement of the inner container 4. When the inner container 4 has a problem, the inner container 4 can be replaced. It is not necessary to replace the entire shielded container.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
