Description

Technical Field

[0001] This utility model relates to the field of nuclear waste container defect detection brackets, and more specifically, to a nuclear waste container defect detection bracket. Background Technology

[0002] Nuclear waste containers are the core containers for the storage and transportation of high-level radioactive nuclear waste. They are mainly used to encapsulate and isolate radioactive waste (such as solidified high-level radioactive waste liquid) generated after the operation of a nuclear reactor or the reprocessing of nuclear fuel. This prevents the leakage of radioactive materials and ensures the safety of personnel, the environment, and facilities. Nuclear waste containers need to be installed and placed for inspection using defect detection brackets.

[0003] However, existing nuclear waste containers come in various shapes, including cylindrical (mainstream), square (small batch), and irregular prism (special packaging). The existing nuclear waste container defect detection bracket is only compatible with the standard cylindrical shape, resulting in a small range of compatibility, low efficiency, and reduced practicality of the device. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a nuclear waste container defect detection bracket.

[0005] According to a first aspect of the present invention, a nuclear waste container defect detection bracket is provided, comprising: a base plate, a side plate, and a top plate. The upper end of the base plate is fixedly provided with a side plate, and the upper end of the side plate is fixedly provided with a top plate. The base plate is provided with a fixing mechanism and a detection mechanism. The fixing mechanism includes a rotating disk, which is disposed above the base plate. A first fixing module and a second fixing module are mounted on the rotating disk via an assembly assembly. The first fixing module and the second fixing module are connected by a connecting block, and both the first fixing module and the second fixing module are fixedly connected by support columns.

[0006] The assembly includes a connecting column, which is bolted to the bottom of the first fixing module and the second fixing module. A mounting base is fixedly connected to the bottom of the connecting column, and a fastening bolt is installed inside the mounting base. The fastening bolt is installed inside a mounting hole, which is formed inside the mounting base and the rotating disk.

[0007] Preferably, a positioning rod is fixedly connected to the bottom end of the mounting base, the positioning rod is inserted into the positioning hole, and the positioning hole is opened inside the rotating disk.

[0008] Preferably, the two sets of connecting blocks are connected by rare earth permanent magnets and positioning pins.

[0009] Preferably, the detection mechanism includes a servo motor, which is installed inside the base plate. The output end of the servo motor is fixedly connected to a drive gear via a coupling. A driven gear is connected to the outside of the drive gear via tooth meshing. A rotating rod is fixedly connected to the upper end of the driven gear. The upper end of the rotating rod is fixedly connected to a rotating disk. An electric cylinder is fixedly connected to the bottom end of the top plate. An ultrasonic instrument is installed on the electric cylinder. A controller is fixedly connected to the outer wall of the side plate. The controller is electrically connected to the servo motor and the electric cylinder.

[0010] Preferably, a support rod is fixedly connected to the bottom end of the rotating disk, and the support rod is rotatably disposed inside the circular groove, which is formed inside the bottom plate.

[0011] Preferably, a support rod is fixedly connected to the bottom end of the driven gear, and the support rod is rotatably connected to the inside of the base plate through a bearing seat.

[0012] 1. This utility model, through the cooperation of a rotating disk, a first fixing module, a second fixing module, a support column, a connecting column, a mounting base, fastening bolts, mounting holes, and connecting blocks, allows for the fixation of nuclear waste containers of different shapes simply by replacing the appropriate first and second fixing modules. For example, for circular and rectangular nuclear waste containers, the appropriate semi-circular first and second fixing modules, as well as the rectangular first and second fixing modules, are engaged with the outside of the nuclear waste container. They are then connected by rare-earth permanent magnets and positioning pins. The bottom end is bolted to the connecting column, and the mounting base is positioned using positioning rods and positioning holes. Finally, fastening bolts are inserted into the mounting holes for fixation. This modular fixing unit allows for convenient fixation of nuclear waste containers of different shapes. The modular fixing structure enables the nuclear waste container defect detection bracket to be adapted and fixed to nuclear waste containers of different shapes, improving the adaptability of the defect detection bracket and allowing it to perform fixed defect detection on various nuclear waste containers of different shapes, thus enhancing the practicality and convenience of the device.

[0013] 2. This utility model utilizes a servo motor, a drive gear, a driven gear, a rotating rod, an electric cylinder, an ultrasonic instrument, and a controller to perform defect detection on nuclear waste containers using an ultrasonic instrument. During the detection process, the controller can start the servo motor, driving the drive gear to rotate. Under the meshing action of the gear teeth, the driven gear rotates synchronously, which in turn drives the rotating rod and the rotating disk to rotate synchronously. This allows the nuclear waste container placed on the rotating disk to rotate synchronously. The controller synchronously controls the electric cylinder to start, causing it to drive the ultrasonic instrument to feed synchronously, improving the defect detection efficiency of the nuclear waste container. This nuclear waste container defect detection bracket uses rotation and lifting feed to perform comprehensive defect detection on the nuclear waste container, improving the efficiency of defect detection and enhancing the practicality and efficiency of the device.

[0025] like Figure 1-4 As shown, one embodiment of this utility model is provided:

[0026] A defect detection bracket for nuclear waste container. The base plate 111, side plate 112, top plate 113, servo motor 311, electric cylinder 315 and controller 317 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art.

[0027] It includes: a base plate 111, a side plate 112, and a top plate 113. The side plate 112 is fixedly installed on the upper end of the base plate 111, and the top plate 113 is fixedly installed on the upper end of the side plate 112. The base plate 111 is provided with a fixing mechanism 2 and a detection mechanism 3. The fixing mechanism 2 includes a rotating disk 211, which is located above the base plate 111. The rotating disk 211 is equipped with a first fixing module 212 and a second fixing module 213 through an assembly assembly. The first fixing module 212 and the second fixing module 213 are connected by a connecting block 221. Both the first fixing module 212 and the second fixing module 213 are fixedly connected by a support column 214.

[0028] The assembly component includes a connecting column 215, which is bolted to the bottom of the first fixing module 212 and the second fixing module 213. A mounting base 216 is fixedly connected to the bottom of the connecting column 215. A fastening bolt 217 is installed inside the mounting base 216. The fastening bolt 217 is installed inside the mounting hole 218, which is opened inside the mounting base 216 and the rotating disk 211.

[0029] When using this nuclear waste container defect detection bracket, the fixing unit on the bracket is modularized. Multiple sets of first fixing modules 212 and second fixing modules 213 are used to fix it, which can adapt and fix nuclear waste containers of different shapes, avoiding the fact that the existing bracket can only fix a single round cylinder.

[0030] A positioning rod 219 is fixedly connected to the bottom end of the mounting base 216. The positioning rod 219 is inserted into the positioning hole 220, which is opened inside the rotating disk 211.

[0031] When assembling the mounting base 216 and the rotating disk 211, the positioning rod 219 is inserted into the positioning hole 220 for installation and positioning. This allows the mounting base 216 and the mounting hole 218 inside the rotating disk 211 to be positioned synchronously, and the positioning rod 219 can be inserted into the mounting hole 218 inside the mounting base 216 and the rotating disk 211 for fixing.

[0032] The two sets of connecting blocks 221 are connected by rare earth permanent magnets and positioning pins.

[0033] The two sets of connecting blocks 221 are connected by rare earth permanent magnets and positioning pins, which allows for quick assembly and disassembly between the first fixing module 212 and the second fixing module 213.

[0034] The testing mechanism 3 includes a servo motor 311, which is installed inside the base plate 111. The output end of the servo motor 311 is fixedly connected to a drive gear 312 via a coupling. The drive gear 312 is externally connected to a driven gear 313 via tooth meshing. A rotating rod 314 is fixedly connected to the upper end of the driven gear 313. The upper end of the rotating rod 314 is fixedly connected to the rotating disk 211. An electric cylinder 315 is fixedly connected to the bottom end of the top plate 113. An ultrasonic instrument 316 is installed on the electric cylinder 315. A controller 317 is fixedly connected to the outer wall of the side plate 112. The controller 317 is electrically connected to the servo motor 311 and the electric cylinder 315.

[0035] When using this nuclear waste container defect detection bracket, the ultrasonic instrument 316 is used to detect defects in the nuclear waste container. During the detection process, the controller 317 can start the servo motor 311, which drives the drive gear 312 to rotate. Under the meshing action of the teeth, the driven gear 313 rotates synchronously, which in turn drives the rotating rod 314 and the rotating disk 211 to rotate synchronously. This allows the nuclear waste container placed on the rotating disk 211 to rotate synchronously. The controller 317 synchronously controls the electric cylinder 315 to start, which drives the ultrasonic instrument 316 to feed synchronously, thereby improving the defect detection efficiency of the nuclear waste container.

[0036] A support rod 319 is fixedly connected to the bottom end of the rotating disk 211. The support rod 319 is rotatably disposed inside the circular groove 320, which is opened inside the base plate 111.

[0037] When the rotating disk 211 rotates, the support rod 319 rotates synchronously inside the circular groove 320, providing stable support for the rotating disk 211 and making the rotation of the rotating disk 211 more stable.

[0038] A support rod 318 is fixedly connected to the bottom end of the driven gear 313, and the support rod 318 is rotatably connected to the inside of the base plate 111 through a bearing seat;

[0039] When the driven gear 313 rotates, the bottom is supported by the support rod 318 and the bearing seat, making its rotation more stable.

[0040] Working principle:

[0041] When using this nuclear waste container defect detection bracket, for nuclear waste containers of different shapes, it is only necessary to replace the appropriate first fixing module 212 and second fixing module 213 for fixing. For example, for round and rectangular nuclear waste containers, the appropriate semi-circular first fixing module 212 and second fixing module 213, as well as the rectangular first fixing module 212 and second fixing module 213, are snapped onto the outside of the nuclear waste container. They are assembled and connected by rare earth permanent magnets and positioning pins. The bottom end is assembled with bolts to connect the column 215. The mounting base 216 is positioned and installed using the positioning rod 219 and positioning hole 220. Finally, the fastening bolt 217 is inserted into the mounting hole 218 for fixing. This modular fixing unit can be used to conveniently fix nuclear waste containers of different shapes.

[0042] When using the nuclear waste container defect detection bracket, the ultrasonic instrument 316 is used to detect defects in the nuclear waste container. During the detection process, the controller 317 can start the servo motor 311, which drives the drive gear 312 to rotate. Under the meshing action of the teeth, the driven gear 313 rotates synchronously, which in turn drives the rotating rod 314 and the rotating disk 211 to rotate synchronously. This allows the nuclear waste container placed on the rotating disk 211 to rotate synchronously. The controller 317 synchronously controls the electric cylinder 315 to start, which drives the ultrasonic instrument 316 to feed synchronously, improving the defect detection efficiency of the nuclear waste container. The operation ends here.

[0043] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
