Technical Field

[0001] The utility model relates to the technical field of radioactive waste, in particular to a radioactive waste transport shielding device. Background Art

[0002] Radioactive waste refers to materials that contain or are contaminated by radioactive nuclides, whose concentration or specific activity is greater than the clean release level specified by the national review and management department, and are expected to no longer be used. At present, many highly radioactive nuclear wastes are generally placed in sealed barrels for temporary storage, and then transported to temporary storage plants for storage. After solidification, packaging and other treatments, they are buried deep in the geological area.

[0003] Shielded barrels containing nuclear waste are usually transported through external transfer equipment during use, which is inconvenient to transport by themselves. In addition, the opening method of most shielded barrels is unreasonable, which increases the chance of people coming into contact with radioactive waste during the placement process and provides low safety for people. Therefore, a radioactive waste transfer shielding device is proposed to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the first embodiment, Figure 1 In the present invention, a radioactive waste transfer shielding device includes a base 1, a transfer structure 2 is provided on the top of the base 1, a shielding structure 3 is provided outside the transfer structure 2, and a universal wheel 4 is fixedly installed on the bottom of the base 1.

[0021] The base 1 drives the transfer structure 2 to move via the universal wheels 4, and at the same time, the shielding cover 201 and the base 1 together wrap the transfer barrel 202, thereby achieving the effect of shielding the radioactive waste.

[0022] In the second embodiment, Figure 1 In the figure, a shielding cover 201 is movably installed on the top of the base 1, a transfer bucket 202 is movably installed on the top of the base 1, a limit block 203 is fixedly installed inside the shielding cover 201, a connecting rod 204 is movably installed outside the limit block 203, a cross bar 205 is fixedly installed outside the connecting rod 204, a slide 206 is rotatably installed outside the cross bar 205, a spring 207 is fixedly installed outside the connecting rod 204, and a pull rope 208 is fixedly installed outside the cross bar 205.

[0023] When the shielding cover 201 covers the outside of the transfer barrel 202, the slide 206 can fit with the outside of the transfer barrel 202, and limit the transfer barrel 202 so that the transfer barrel 202 remains stable on the top of the base 1.

[0024] Example 3, in Figure 1 In the figure, an adjusting box 301 is fixedly installed on the top of the base 1, a rotating rod 302 is rotatably installed inside the adjusting box 301, a gear 303 is fixedly installed outside the rotating rod 302, a motor 304 is fixedly installed inside the adjusting box 301, a baffle 305 is fixedly installed outside the rotating rod 302, a screw 306 is threadedly connected to the inside of the shielding cover 201, a hydraulic rod 307 is fixedly installed on the bottom of the base 1, and a support plate 308 is fixedly installed on the bottom of the hydraulic rod 307.

[0025] When the baffle 305 is in contact with the feed port, the shielding cover 201 remains sealed, so that the radioactive waste is isolated from the outside by the shielding cover 201. When the shielding cover 201 leaves the transfer barrel 202, the transfer barrel 202 can be lifted to discharge the radioactive waste.

[0026] To sum up, when storing radioactive waste into the transfer barrel 202, the radioactive waste transfer shielding device turns on the motor 304 to drive one of the gears 303 to rotate, so that one of the gears 303 drives the gear 303 outside the rotating rod 302 to rotate, so that the rotating rod 302 can drive the baffle 305 away from the feed port, and the radioactive waste is stored into the transfer barrel 202 through the feed port. When the transfer barrel 202 is driven to move by the universal wheel 4 at the bottom of the base 1, the transfer barrel 202 is facilitated to transfer while storing radioactive waste in the transfer barrel 202, which solves the problem that shielding barrels containing nuclear waste are generally transferred by external transfer equipment during use, which is inconvenient for them to transfer themselves, and the opening method of most shielding barrels is unreasonable, which increases the chance of people coming into contact with radioactive waste during the placement process and provides low safety for people.
