Technical Field

[0001] This utility model relates to the field of nuclear power transportation, and in particular to an outer packaging box for an irradiation monitoring tube transport container. Background Technology

[0002] An irradiation monitoring tube (IRBT) is a device in which the base material and weld material of a reactor pressure vessel are prepared as samples, placed inside a stainless steel tube, and fixed to the outside of the reactor internals basket along the height of the active section of the reactor core. Its main purpose is to be extracted according to a schedule during the reactor's lifespan for performance testing and analysis to monitor and predict changes in the pressure vessel's material composition after irradiation. Because IRBTs are subjected to long-term neutron irradiation from the reactor, they possess strong radioactivity. Therefore, the transport of IRBTs requires a specific transport container to shield their radioactivity and ensure safety during transport. Currently, most transport containers are cylindrical, which makes direct transport inconvenient and increases the risk of radiation exposure to personnel. Therefore, a specialized tool for transporting IRBTs is needed. Utility Model Content

[0019] Figures 1 to 7 This invention illustrates an outer packaging box for a transport container of an irradiation monitoring tube 5, wherein the irradiation monitoring tube 5 is provided with lifting lugs 51 for hoisting. This outer packaging box for transporting the irradiation monitoring tube 5 can be used for the storage and transport of the irradiation monitoring tube 5 inside a nuclear power plant. It may include a box bottom 1 covered with radiation-proof material, a box cover 2 sleeved on the upper part of the box bottom 1 and covered with radiation-proof material, a plurality of fixing components 3 provided on the box bottom 1 for fixing the irradiation monitoring tube 5, and a flip support 4 provided on the box bottom 1 for rotatably connecting the lifting lugs 51; wherein the box bottom 1 is provided with a plurality of locking components for locking and fixing the box cover 2.

[0020] The lifting lug 51 of the irradiation monitoring tube 5 is placed on the flip support 4 on the bottom of the box 1. Using the flip support 4 as the rotation axis, the irradiation monitoring tube 5 flips and lies on the fixing component 3. The fixing component 3 fixes the irradiation monitoring tube 5. Then, the box cover 2 is placed on the irradiation monitoring tube 5, and the box cover 2 and the bottom of the box 1 are completely fixed by the locking component. This completes the installation and fixing of the irradiation monitoring tube 5, and realizes the fixation of the irradiation monitoring tube 5 transport container during transportation, which meets the requirements of the irradiation monitoring tube 5 transport container for automobile transportation.

[0021] Understandably, radiation shielding materials are generally made of materials such as lead and graphite.

[0022] In one specific embodiment, there are two or more fixing components 3, because the two fixing components 3 completely restrict the radial movement of the irradiation monitoring tube 5, and the flip support 4 completely restricts the axial movement of the irradiation monitoring tube 5.

[0023] Furthermore, in this application, based on the weight and size of the irradiation monitoring tube 5, there are three fixing components 3. The three fixing components 3 can share the weight of the irradiation monitoring tube 5 and the impact during handling, thereby improving its service life.

[0024] Figure 7 The flip support 4 is shown in one embodiment and may be respectively disposed on both sides of the irradiation monitoring tube 5. The flip support 4 includes a base plate 41 detachably connected to the bottom of the box 1 and a support plate 42 disposed on the base plate 41. The support plate 42 is provided with a support groove 43 that matches the shape of the lifting lug 51. The base plate 41 is fixed on the bottom of the box 1. The support plate 42 supports the lifting lug 51 of the irradiation monitoring tube 5 upward. The support groove 43 is used to restrict the movement of the lifting lug 51 so that the irradiation monitoring tube 5 can rotate about the support groove 43 as the axis.

[0025] In one specific embodiment, the bottom shape of the support groove 43 matches the shape of the connection point of the lifting lug 51, and the support groove 43 and the lifting lug 51 form a surface contact rather than a line or point contact, which reduces the wear of the lifting lug 51 and improves the service life of the irradiation monitoring tube 5.

[0026] Figure 1 and Figure 6 In one embodiment, the fixing component 3 may include a fixing base 31 detachably connected to the bottom of the box 1, a retaining ring assembly 32 provided on the upper part of the fixing base 31 and matching the shape of the irradiation monitoring tube 5 to fix the irradiation monitoring tube 5, and connecting components 35 provided on both sides of the fixing base 31 for fixing the retaining ring assembly 32. The fixing base 31 is fixed to the bottom of the box 1, the retaining ring assembly 32 fixes the irradiation monitoring tube 5, and the connecting components 35 fix and lock the retaining ring assembly 32. The inner diameter of the retaining ring is reduced by the connecting components 35 to lock the irradiation monitoring tube 5, thereby fixing the irradiation monitoring tube 5 to the bottom of the box 1.

[0027] Figure 6 In one embodiment, the retaining ring assembly 32 may include a lower retaining ring 33 connected to the fixed base 31 and an upper retaining ring 36 abutting against the lower retaining ring 33. Both ends of the lower retaining ring 33 and the upper retaining ring 36 are provided with connecting portions 34 in the direction away from the irradiation monitoring tube 5. The connecting portions 34 are provided with mounting grooves for detachable connection with the connecting assembly 35. The upper retaining ring 36 and the lower retaining ring 33 surround the irradiation monitoring tube 5. The connecting assembly 35 locks and fixes the upper retaining ring 36 and the lower retaining ring 33 through the connecting portions 34 and the mounting grooves.

[0028] Figure 6The connecting assembly 35, in one embodiment, may include two bolt seats 302 disposed at both ends of the fixed base 31, a hinge bolt 301 that snaps into the mounting groove and is hinged to the bolt seats 302, and a hinge nut 38 for fixing the upper retaining ring 36 and the lower retaining ring 33 and is threadedly connected to the hinge bolt 301. The hinge nut 38 locks the gap between the upper retaining ring 36 and the lower retaining ring 33, thereby reducing the distance between the upper retaining ring 36 and the lower retaining ring 33 and reducing the inner diameter of the upper retaining ring 36 and the lower retaining ring 33, thus limiting the movement space of the irradiation monitoring tube 5.

[0029] In one specific embodiment, the connecting assembly 35 includes a pin 303 passing through the bolt seat 302 and the hinge bolt 301. The hinge bolt 301 can rotate around the pin 303. After loosening the hinge nut 38, the hinge bolt 301 rotates to disengage from the mounting slot without falling off, making installation and disassembly more convenient.

[0030] In one specific embodiment, a hinge washer 39 is provided at the hinge nut 38. The hinge washer 39 increases the contact area with the connecting part 34, thereby increasing the friction between the hinge nut 38 and the connecting part 34.

[0031] Figure 6 The lower retaining ring 33 and the upper retaining ring 36 are shown in one embodiment. The inner diameter of the ring formed by the lower retaining ring 33 and the upper retaining ring 36 is less than or equal to the outer diameter of the irradiation monitoring tube 5. The lower retaining ring 33 and the upper retaining ring 36 can completely lock the irradiation monitoring tube 5 to prevent the irradiation monitoring tube 5 from moving.

[0032] Figure 5 In one embodiment, the bottom of the box 1 may include a plurality of arrayed positioning holes 18. A plurality of fixing components 3 and a flip support 4 are fixed through the positioning holes 18. The bottom plate 41 of the flip support 4 is provided with seat holes 304 that match the positioning holes 18. The flip support 4 is fixed by screws passing through the seat holes 304 and the positioning holes 18. The fixed base 31 is provided with corresponding seat holes 304. The fixed base 31 is fixed by screws passing through the seat holes 304 and the positioning holes 18.

[0033] Figure 5 The bottom of the box 1, as shown in one embodiment, may include a bottom plate 12 disposed at the bottom of the bottom of the box 1, a bottom frame assembly 11 disposed at the edge of the bottom plate 12 and used to support the box cover 2, and a locking assembly disposed on the bottom frame assembly 11.

[0034] In one specific embodiment, the box bottom frame assembly 11 includes a short side 14 of the box bottom steel and a long side 13 of the box bottom steel.

[0035] Figure 5The locking assembly shown in one embodiment may include a rotating seat 16 fixed to the frame assembly 11, a locking bolt 19 hinged to the rotating seat 16, and a locking nut 17 for locking the lid 2, the locking nut 17 locking the distance between the lid 2 and the bottom 1 of the box to prevent the lid 2 from detaching from the bottom 1 of the box.

[0036] Figure 4 The lid 2, in one embodiment, may include a top frame 21, a top skin 24 covering the top frame 21, a plurality of vertical frames 27 disposed below the top frame 21, and a bottom frame 26 disposed below the vertical frames 27.

[0037] In one specific embodiment, the top frame 21 includes a short side 23 and a long side 22 of the top steel profile, and the vertical frame 27 is provided with a side skin 25.
