[0032] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0033] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0034] Reference Figure 1 , Figure 2 , this embodiment provides a flipping mechanism, including,

[0035] A supporting component 1, the supporting component 1 comprises a bearing assembly 11 and a lifting component 12 adapted to be installed on the top of the bearing assembly 11;

[0036] A driving component 2, the driving component 2 comprises a power component 21 and a regulating component 22 adapted to be installed with the power component 21;

[0037] A placement component 3, the placement component 3 includes a mounting component 31 and a trigger component 32 fixedly connected to the bottom end of the mounting component 31;

[0038] The supporting components 1 are arranged in two groups. The two groups of supporting components 1 are used for carrying and installing the driving components 2 and the placing components 3 . The driving components 2 are used for adjusting the angle of the placing components 3 .

[0039] After the storage mechanism 4 is placed on the surface of the placement component 3, the placement component 3 can be flipped by starting the driving component 2, thereby driving the storage mechanism 4 to flip, ensuring stable and convenient removal of the nuclear fuel.

[0040] The support component 1 can effectively support the placement component 3, and when the storage mechanism 4 is placed on the placement component 3, the placement component 3 can avoid causing extra pressure on the driving component 2, and can ensure the levelness of the placement component 3. It can ensure that the storage mechanism 4 is more convenient to install and place, and can also reduce the pressure on the driving component 2, thereby increasing the overall service life of the driving component 2.

[0041] As an embodiment provided in this application, Figure 3 , the bearing assembly 11 includes a base frame 111 and a connecting frame 112 installed on the top of the base frame 111 by bolts;

[0042] A protrusion is disposed on the top of the connecting frame 112 .

[0043] The lifting component 12 includes a right-angle plate 121 slidably connected to the top of the connecting frame 112, a first spring 122 fixedly connected to the outside of the right-angle plate 121, and a supporting plate 123 fixedly connected to the top of the first spring 122;

[0044] A groove is formed at the bottom of the right-angle plate 121 , and the right-angle plate 121 slides by cooperating with the protrusion at the top of the connecting frame 112 through the groove.

[0045] When the mounting plate 311 is located above the support plate 123, if the mounting plate 311 on the surface of the support plate 123 is not installed with the container 42, the mounting plate 311 can be supported by the elasticity of the four groups of first springs 122 to prevent the mounting plate 311 from cooperating with the connecting rod 222. This can not only prevent the mounting plate 311 from causing unnecessary pressure on the connecting rod 222, but also ensure that the support plate 123 can remain in a horizontal state, so that the container 42 can be placed in a horizontal state above the mounting plate 311.

[0046] When the mounting plate 311 on the surface of the support plate 123 is installed with the container 42, the weight of the container 42 will drive the mounting plate 311 to squeeze the first spring 122, and eventually the push block 321 at the bottom of the mounting plate 311 will be inserted into the slot 213 of the rotating shaft 212. At this time, starting the motor 211 can realize the rotation of the mounting plate 311, thereby completing the angle change of the container 42.

[0047] As an embodiment provided in this application, Figure 1 to Figure 7 The power assembly 21 includes a motor 211 disposed on a stand, a rotating shaft 212 fixedly connected to an output end of the motor 211 , and a notch 213 opened on the outer side of the rotating shaft 212 . A circular groove 214 is opened inside the rotating shaft 212 .

[0048] The regulating component 22 includes a sliding rod 221 slidably connected to the inside of the rotating shaft 212, a connecting rod 222 fixedly connected to the outside of the sliding rod 221, and a ring 223 fixedly connected to one end of the connecting rod 222. One end of the sliding rod 221 is fixedly connected to a second spring 224, and the ring 223 is located at the bottom end of the right-angle plate 121.

[0049] The trigger assembly 32 includes a push block 321 and a ball 322 disposed at the bottom end of the push block 321 . The push block 321 is fixedly connected to the bottom end of the mounting plate 311 .

[0050] The mounting plate 311 plays a key role in the loading and unloading process of the container 42. When the container 42 is correctly placed on the mounting plate 311, the push block 321 will automatically slide into the notch 213 to achieve precise docking. This action triggers the push block 321 to apply pressure to the slide bar 221, pushing the slide bar 221 to slide along the set path, while compressing the second spring 224. The movement of the slide bar 221 transmits power through the ring 223, thereby driving the right-angle plate 121, and finally causing the support plate 123 to detach from the bottom end of the mounting plate 311, clearing the way for the start of the motor 211 and the flipping operation of the container 42.

[0051] If the operation sequence is reversed, that is, the motor 211 is started first to rotate the shaft 212, and then the container 42 is placed on the mounting plate 311, the ball 322 at the bottom of the push block 321 will cooperate with the outer edge of the shaft 212 to ensure smooth rotation of the shaft 212. When the notch 213 and the push block 321 are aligned, the weight of the container 42 will cause the push block 321 to be tightly engaged with the notch 213 to achieve a snap connection, thereby completing the flipping action.

[0052] This design not only provides a flexible operation mode, allowing the choice of placing the container 42 first or starting the motor 211 first according to the actual situation, but also improves the convenience of the loading and unloading process and the durability of the equipment by reducing unnecessary friction and wear. Such a mechanism not only ensures the safety and reliability of operation, but also extends the service life of the equipment, reduces maintenance costs, and improves overall work efficiency. Through this carefully designed mechanical linkage, the equipment can adapt to different operating environments and ensure safe and efficient loading and unloading of the container 42.

[0053] As an embodiment provided in this application, Figure 6 The mounting assembly 31 includes a mounting plate 311 and a mounting cavity 312 opened at the top of the mounting plate 311 , and the mounting plate 311 is located on the upper side of the support plate 123 .

[0054] The installation of the connecting frame 41 and the installation plate 311 can be completed by placing the clamping block 411 inside the installation cavity 312 .

[0055] As an embodiment provided in this application, Figure 8 A nuclear fuel container has a flipping mechanism, and also includes a storage mechanism 4, which includes a connecting frame 41 and a container 42 arranged outside the connecting frame 41.

[0056] The connecting frame 41 includes a clamping block 411 , a square plate 412 fixedly connected to the top of the clamping block 411 , and a fixing frame 413 fixedly connected to the top of the square plate 412 .

[0057] The container 42 includes a cylinder 421 , a cover 422 bolted to one end of the cylinder 421 , and a handle 423 fixedly connected to the outer side of the cover 422 .

[0058] When the container 42 is turned vertically, the bolts connecting the cylinder 421 and the cover 422 are removed by a wrench, and then the cover 422 is opened to complete the removal of the internal nuclear fuel.

[0059] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
