[0002] Currently, during the decommissioning and dismantling of nuclear facilities, the repackaging of waste retrieved from areas with high radioactivity presents numerous challenges, such as the reliability of container hoisting, container contamination, and packaging efficiency. Current solutions typically involve hoisting containers into the radioactive zone, loading them with waste, hoisting them out of the zone, and then decontaminating them. However, in areas with high radioactivity, the work area is often heavily contaminated. Once the waste containers enter, their outer surfaces become significantly contaminated, increasing the difficulty of subsequent decontamination. Furthermore, the use of hoisting equipment for transporting waste places high demands on the reliability and efficiency of the hoisting operation. Therefore, the efficiency of repackaging the retrieved waste is relatively low. Summary of the Invention

The receiving mechanism is located below the flipping mechanism and is used to receive the radioactive waste dumped after the waste dumping bucket is flipped.

[0025] The radioactive waste dumping device in this embodiment uses a waste transfer dumping bucket and a passive tipping mechanism to dump waste, which can improve waste retrieval efficiency, reduce decontamination difficulty, and improve the reliability of the waste dumping operation.

[0026] Example 2

[0027] like Figures 1-5As shown, this embodiment provides a radioactive waste dumping device, including: a support 1, a waste dumping bucket 3, a moving mechanism, a main body fixing frame 5, a flipping mechanism, and a receiving mechanism. The moving mechanism is mounted on the support 1 and connected to the waste dumping bucket 3, and is used to move the waste dumping bucket 3. The flipping mechanism is mounted on the main body fixing frame 5 and is used to receive the waste dumping bucket 3 placed on the flipping mechanism by the moving mechanism and to flip the waste dumping bucket 3. The receiving mechanism is located below the flipping mechanism and is used to receive the radioactive waste dumped after the waste dumping bucket 3 is flipped.

[0028] The radioactive waste dumping device in this embodiment achieves reliable and efficient waste packaging. The support 1 in this embodiment is a mobile overhead crane. The waste dumping bin 3 is fixedly connected to the moving mechanism, and this permanent connection ensures high reliability during retrieval. Using the waste dumping bin 3, permanently connected to the moving mechanism of the hoisting equipment, for waste transfer prevents waste packaging containers from entering areas with high radioactivity. The lightweight main frame 5 is designed to secure the waste dumping bin 3 and the tipping platform 4.

[0029] Preferably, the moving mechanism includes: a first moving mechanism and a second moving mechanism. The first moving mechanism includes: a first driving mechanism, a first transmission mechanism, and a first moving component. The first moving component is slidably connected to the bracket 1. The first driving mechanism is connected to the first transmission mechanism. The first transmission mechanism is connected to the first moving component. The first driving mechanism drives the first moving component to move along a first direction through the first transmission mechanism. The first moving component drives the waste dumping bucket 3 to move along the first direction. The second moving mechanism includes a second driving mechanism and a second transmission mechanism. The second driving mechanism is connected to the second transmission mechanism, which is connected to the waste dumping bin 3. The second transmission mechanism is connected to the first moving component. The second driving mechanism drives the waste dumping bin 3 to move along a second direction, which is perpendicular to the first direction. The second direction is the up-down direction.

[0030] The bracket 1 includes: a bracket body and a slide rail disposed on the bracket body. The first moving member includes: a first moving member body and a slider disposed on the first moving member body. A first driving mechanism drives the slider of the first moving member to slide along the slide rail of the bracket 1 in a first direction.

[0031] The waste dumping bin 3 is connected to the moving mechanism. The moving mechanism is pre-set with a positioning function to ensure that the waste dumping bin 3 arrives accurately at the dumping station and loading station. Combined with the limit setting of the tilting table 4, it enables precise control of the waste dumping bin 3.

[0032] Preferably, the tilting mechanism includes: a tilting platform 4, a counterweight 16, a limiting frame 18, a spring 23, a tilting shaft, a bearing, and a tilting shaft support. The tilting platform 4 has a tilting shaft at its bottom, which is mounted on the tilting shaft support via a bearing. The tilting shaft support is mounted on the main body fixing frame 5. The counterweight 16 is positioned below the tilting platform 4, and the limiting frame 18 is positioned on the tilting platform 4. The limiting frame 18 is used to limit the waste dumping bucket 3 placed on the tilting platform 4. One end of the spring 23 is connected to the tilting platform 4, and the other end is connected to the main body fixing frame 5. The spring 23 is used to reset the waste dumping bucket 3 after it has been tilted and tilted. The counterweight 16 is eccentrically positioned at the bottom of the tilting platform 4 to ensure that the waste dumping bucket 3 tilts as required during tilting, and the tilting platform 4 returns to its initial position after tilting is complete. The tilting mechanism is a purely mechanical structure design. In this embodiment, the counterweight 16 is a counterweight rod.

[0033] The bottom of the tilting platform 4 of the radioactive waste dumping device is connected by a spring 23, allowing the dumping and resetting process of the waste dumping container 3 to be achieved passively. The angle between the spring 23 and the vertical limiting frame 18 is approximately 30-50°, and the tension of the spring 23 is between 80-330N, which ensures that the waste dumping container 3 can stably leave the tilting platform 4 and complete the gravity-free dumping of the waste dumping container 3.

[0034] The bottom of the tilting platform 4 of the tilting device is connected by spring 23 to ensure that the tilting and resetting process of the waste bin is achieved in a passive manner. The structure is simple, there are no electronic components, and the tilting process is reliable.

[0035] A passive tilting mechanism is adopted. After the waste dumping bin 3 is placed in, it can be used to transfer the waste in the waste dumping bin 3 and put the waste into the packaging container. The tilting shaft of the tilting device is located at the bottom of the tilting table 4. The distance between the tilting shaft and the center line of the tilting table 4 is about 3-6cm. It is fixed by screws and is set eccentrically. After the dumping is completed, the waste dumping bin 3 is lifted out from the tilting mechanism, and the tilting mechanism can be freely reset. Preferably, the limiting frame 18 includes an arc-shaped side plate and a vertical side plate. The arc-shaped side plate is connected to the tilting table 4, and the vertical side plate is also connected to the tilting table 4. A slot 21 is provided between the arc-shaped side plate and the vertical side plate. The slot 21 is used to guide the placed waste dumping bin 3, thereby controlling the posture of the waste dumping bin 3. The arc-shaped side plate and the vertical side plate are connected to the tilting table 4 by welding.

[0036] Preferably, the limiting frame 18 includes a limiting frame body and observation holes 22 disposed on the limiting frame body. There are at least two observation holes 22, which are used to reduce the overall weight and facilitate the operator to observe the positioning status of the waste dumping bucket 3.

[0037] Preferably, the radioactive waste dumping device further includes a limiting slider 20, which is disposed within the limiting frame 18. After the waste dumping bucket 3 enters the limiting frame 18, it slides along the limiting slider 20 to the first preset position on the flipping table 4.

[0038] At least two triangular limiting sliders 20 are provided at the bottom of the limiting frame 18. The waste dumping bucket 3 moves along the edge of the limiting slider 20 by gravity and slides to the first preset position on the flipping table 4 with the help of the limiting slider 20.

[0039] Preferably, the radioactive waste dumping device further includes: a first limiting mechanism 8, disposed on the support 1, the first limiting mechanism 8 being used to limit the moving mechanism, so that the moving mechanism moves on the support 1 to a second preset position.

[0040] Preferably, the radioactive waste dumping device further includes: a second limiting mechanism 9 connected to the main body fixing frame 5, the second limiting mechanism 9 being used to limit the flipping mechanism, so that the flipping mechanism flips to a third preset position on the main body fixing frame 5.

[0041] The second limiting mechanism 9 is the second slot. The second positioning point 13 of the waste dumping bucket 3 cooperates with the second slot on the main body fixing frame 5 to prevent the waste dumping bucket 3 from continuing to slide.

[0042] Preferably, the receiving mechanism includes a guide chute 6 and a receiving container 7. The guide chute 6 is connected to the main body fixing frame 5 and is located below the tilting mechanism. The guide chute 6 is used to receive radioactive waste dumped from the waste dumping container 3. The receiving container 7 is located below the guide chute 6 and is used to receive radioactive waste discharged from the guide chute 6. The guide chute 6 is fixed to the main body fixing frame 5 with screws.

[0043] The bottom projection view of guide chute 6 is an inverted trapezoidal structure. The lower side connects to a 200L steel drum (receiving container 7), with a width of 300-500mm. The upper side connects to a small waste dumping bucket, with a width of 600-900mm. The guide chute 6 has a depth of approximately 100-200mm. The top of guide chute 6 is fitted with a rolled edge to reduce waste ejection and falling during dumping. Waste is collected in the steel drum for final centralized processing.

[0044] In this embodiment, the receiving container 7 is a packaging container, and the receiving container 7 is a standard steel drum.

[0045] To achieve the effect of dumping waste into the receiving container 7, the tilting table 4 is designed with a limiting frame 18 based on the requirements of the receiving container 7 for receiving waste. On this basis, by setting a guide chute 6 on the dumping device, the sliding range of the dumped waste can be constrained so that the dumped waste can be loaded into the receiving container 7. The above settings enable the dumping device to have the function of loading waste into the receiving container 7.

[0046] A passive tipping mechanism is used. After the waste dumping container 3 is placed in, it can be used to transfer the radioactive waste in the loaded waste dumping container 3 and realize the loading of radioactive waste into the packaging container. The tipping shaft of the tipping mechanism is located at the bottom of the tipping platform 4. The distance between the tipping shaft and the center line of the tipping platform 4 is about 3-6cm. The tipping shaft is fixed to the bottom of the tipping platform 4 with screws. The tipping shaft is eccentrically set. After the dumping is completed, the waste dumping container 3 is lifted out of the tipping mechanism, and the tipping mechanism can be freely reset.

[0047] Preferably, the radioactive waste dumping device further includes: a third limiting mechanism 10, which is disposed on the support platform, and the receiving container 7 is placed on the support platform. The third limiting mechanism 10 is used to limit the receiving container 7 so that the receiving container 7 is in a fourth preset position.

[0048] Specifically, in this embodiment, the first driving mechanism is a first motor, the first transmission mechanism is a pulley, and the first moving part is a drum 11. The second driving mechanism is a second motor, and the second transmission mechanism includes a wire rope and a hook. The wire rope is connected to the hook, and the hook is connected to a lifting lug 12. The waste dumping bin 3 includes: a waste dumping bin body, a lifting lug 12 disposed on the waste dumping bin body, and a wire rope connected to the hook. The first motor drives the drum 11 to move the waste dumping bin 3 from the waste collection station to the dumping station. A first limiting mechanism 8 is provided on the bracket 1 to accurately move the waste dumping bin 3 to the dumping station (second preset position); a second limiting mechanism 9 controls the dumping posture of the waste dumping bin 3; and a third limiting mechanism 10 fixes the position of the receiving container 7 to ensure coordination between dumping and collection.

[0049] Waste dumping bin 3 is used to store waste, and its structural diagram is shown below. Figure 2As shown, the waste dumping bin 3 is frustum-shaped, with an upper diameter of Φ200-600mm, which is larger than the lower diameter by approximately 50-200mm. The waste dumping bin body is equipped with lifting lugs 12 for connecting to the moving mechanism. When the waste dumping bin 3 moves to the first limiting mechanism 8 and is stopped, the steel cable is released, and the waste dumping bin 3 descends to the tilting platform 4. The first positioning point 14 of the waste dumping bin 3 contacts the limiting frame 18, and the waste dumping bin 3 slides along the top edge of the limiting frame 18 under gravity. The first positioning point 14 of the waste dumping bin 3 engages with the third positioning point 17 of the limiting frame 18, fixing the waste dumping bin 3 in place. When the tilting platform 4 tilts to the dumping point, the waste dumping bin 3 tends to continue sliding downwards under gravity. The second positioning point 13 of the waste dumping bin 3 engages with the limiting frame 18 to prevent further sliding. The first positioning point 14 is below the second positioning point 13.

[0050] The tilting platform 4 includes a support frame 19 and a chassis. The support frame 19 is mounted on the main body fixing frame 5, and the chassis is positioned above the support frame 19. The chassis is connected to the limiting frame 18 and is connected to the arc-shaped side plate and the vertical side plate, respectively. The tilting mechanism works in conjunction with the waste dumping bin 3 to complete the waste dumping and resetting actions. The counterweight 16 is used for eccentric counterweighting. By balancing the weight of the support frame 19, chassis, limiting frame 18, and empty waste dumping bin 3, the waste dumping bin 3 remains vertical when there is no weight inside. After a weight is placed inside, the tilting action of the waste dumping bin 3 is completed by the shift of the center of gravity caused by the eccentricity.

[0051] Preferably, the radioactive waste dumping device further includes a monitoring mechanism mounted on the support 1. The monitoring mechanism monitors the moving mechanism, the flipping mechanism, and the receiving mechanism. Specifically, in this embodiment, the monitoring mechanism is a camera 2, which is a high-definition camera used to monitor the actions of the dumping device and assist operators in completing the dumping operation.

[0052] The radioactive waste dumping device in this embodiment is applicable not only to cut radioactive waste packaging, but also to packaging forms of other types of waste.

[0053] In this embodiment, the radioactive waste dumping device employs a passive control method. The waste dumping container 3 is connected to a moving mechanism. After the moving mechanism reaches a predetermined position, the waste dumping container 3 is placed on the tilting platform 4. A counterweight 16 is positioned on one side of the bottom of the tilting platform 4. Utilizing the principle of eccentricity, when radioactive waste needs to be dumped, the waste dumping container 3 automatically tilts to one side under the combined action of gravity and the eccentric counterweight, achieving passive dumping of the waste inside. During the dumping process, combined with the limiting settings of the tilting platform 4, precise control of the waste dumping container 3 is achieved. The bottom of the tilting platform 4 of the dumping device uses a spring 23 connection to ensure that the dumping and resetting process of the waste container is passively controlled. This design abandons the traditional power-driven method, which not only simplifies the equipment structure and reduces equipment costs, but also significantly improves the reliability of the equipment and significantly reduces the failure rate due to the reduction of complex power components.

[0054] The radioactive waste dumping device in this embodiment employs a purely mechanical design. The entire dumping device is primarily composed of mechanical parts, avoiding the use of electronic components and complex power systems. The advantage of a purely mechanical structure lies in its high stability and resistance to interference from the irradiation environment. Moreover, due to its simple structure, it requires almost no maintenance under normal use, truly achieving maintenance-free operation, further reducing operating costs and the radiation risks associated with maintenance.

[0055] Specifically, in this embodiment, the receiving container 7 is a packaging container, and the radioactive waste dumping device in this embodiment meets the requirement of loading the radioactive waste retrieved from the high-radioactivity area into the relevant packaging container. The radioactive waste dumping device is a passive structure. In the case of radioactive waste retrieval and packaging during nuclear facility decommissioning, workers remotely operate a robotic arm to grab the metal pipe segments and cut pieces generated from the cutting process, load them into the waste dumping bucket 3, and lift it out of the radiation zone. After the waste dumping bucket 3 is lifted out, a flipping mechanism is used to load the cut waste from the waste dumping bucket 3 into the receiving container 7. The receiving container 7 is a steel drum or steel box, offering high operational reliability and efficiency. Retrieving high-radioactivity waste is difficult. Generally, when packaging containers are hoisted into the radiation zone to load waste, their outer surfaces become contaminated, requiring sophisticated decontamination methods and resulting in low waste packaging efficiency. The waste packaging process in this embodiment avoids the waste dumping bucket 3 (steel drum or steel box) entering areas with high radioactivity, reducing the difficulty of decontaminating the outer surface of the container and improving waste packaging efficiency.

[0056] The radioactive waste dumping device in this embodiment, designed to meet the actual needs of packaging the cut radioactive waste after retrieval, employs a waste dumping bucket 3 and a passive flipping mechanism in conjunction with the waste dumping and packaging process. This improves waste retrieval efficiency, reduces decontamination difficulty, and enhances the reliability of the waste dumping operation, providing a reliable and efficient processing method for packaging cut radioactive waste.

[0057] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
