[0035] Please refer to Figure 1The embodiment of the utility model provides a vertical packaging and transportation device for a reactor core module, which is used for the transportation of the reactor core module. The reactor core module includes a pressure vessel 1 and an evaporator 2 arranged in the pressure vessel 1. The outer wall of the upper part of the pressure vessel 1 is formed with an outer support platform 11. The vertical packaging and transportation device for the reactor core module includes a vertical support structure 3. The vertical support structure 3 includes a lower support frame 31 and an upper support frame 32. The lower support frame 31 is formed with a receiving cavity 311 with an upper end opening. The receiving cavity 311 is used for receiving the lower part of the pressure vessel 1. The upper support frame 32 is arranged at the upper end of the lower support frame 31 and is located on the opening side of the receiving cavity 311. The upper end of the upper support frame 32 is provided with a clamping mechanism 33. The clamping mechanism 33 is used to clamp the outer support platform 11 of the pressure vessel 1 accommodated in the receiving cavity 311, so that the outer support platform 11 and the upper support frame 32 are relatively fixed.

[0036] Specifically, four outer support platforms 11 may be provided, and the four outer support platforms 11 are evenly distributed along the circumference of the pressure vessel 1 . Accordingly, four upper support frames 32 may be provided, and the four upper support frames 32 are evenly distributed along the circumference of the opening of the accommodating chamber 311 .

[0037] In this embodiment, the accommodating chamber 311 formed on the lower support frame 31 can be used to accommodate the lower part of the pressure vessel 1. The opening of the accommodating chamber 311 is located at the upper end, which just allows the pressure vessel 1 to enter the accommodating chamber 311 from top to bottom, so that the pressure vessel 1 as a whole can be in a vertical state; the upper support frame 32 is located on the opening side of the accommodating chamber 311, and the upper end of the upper support frame 32 is provided with a clamping mechanism 33, which can play a role in clamping the outer support platform 11. Therefore, when the clamping mechanism 33 clamps the outer support platform 11, the outer support platform 11 and the upper support frame 32 can be relatively fixed, so that the pressure vessel 1 and the vertical support structure 3 are relatively fixed. In this way, the evaporator 2 welded to the pressure vessel 1 at the upper end will also be in a vertical state, and the whole will always be in a vertical state and consistent with the normal welding posture, and the upper end weld will not be broken due to posture changes, thereby avoiding damage to the reactor core module during transportation; after the pressure vessel 1 and the vertical supporting structure 3 are relatively fixed, the pressure vessel 1 can be prevented from moving relative to the vertical supporting structure 3 during transportation, further avoiding damage to the reactor core module during transportation.

[0038] Optionally, see Figure 1The clamping mechanism 33 includes a supporting structure 331, a clamping member 332 and a connecting screw 333. The supporting structure 331 is arranged at the upper end of the upper supporting frame 32, and the clamping member 332 is located above the supporting structure 331. The horizontal ends of the clamping member 332 are respectively connected to the upper end of the upper supporting frame 32 through the connecting screw 333. A clamping space for clamping the outer support platform 11 is defined between the clamping member 332 and the supporting structure 331.

[0039] In this embodiment, the clamping space defined by the clamping piece 332 and the supporting structure 331 is for the outer support platform 11 to extend into. When the connecting screw 333 is rotated downward, the clamping piece 332 can press the outer support platform 11, so that the outer support platform 11 is fixed between the clamping piece 332 and the supporting structure 331, thereby clamping the outer support platform 11. The structure is simple, easy to operate, and has good clamping force.

[0040] Optionally, see Figure 2 The support structure 331 includes a fixed seat 3311 and a lifting block 3312. The fixed seat 3311 is fixed to the upper end of the upper support frame 32. The upper end of the fixed seat 3311 is formed with a first inclined surface 3311a which gradually tilts upward in a direction away from the opening of the accommodating chamber 311. The lifting block 3312 is arranged above the fixed seat 3311, and the lower end of the lifting block 3312 is provided with a second inclined surface 3312a which slidably cooperates with the first inclined surface 3311a. The lifting block 3312 is movably arranged in a direction away from the opening of the accommodating chamber 311, so that the second inclined surface 3312a slides along the first inclined surface 3311a, thereby causing the lifting block 3312 to rise or fall.

[0041] For details, please refer to Figure 2 The end of the lifting block 3312 away from the opening of the accommodating chamber 311 is threaded with a clamping screw 3313, and the clamping screw 3313 is extended in a direction away from the opening of the accommodating chamber 311. The end of the fixed seat 3311 away from the opening of the accommodating chamber 311 is provided with a notch groove 3311b with an open upper end, and the clamping screw 3313 passes through the notch groove 3311b. In this way, when the clamping screw 3313 is rotated, the lifting block 3312 can be driven to move in a direction away from the opening of the accommodating chamber 311.

[0042] In this embodiment, the lifting block 3312 can support the outer support platform 11 in the clamping space. In this way, before the clamping piece 332 presses the outer support platform 11, the lifting block 3312 can be controlled to move up and down to drive the outer support platform 11 to move up and down. The lifting blocks 3312 of the multiple clamping mechanisms 33 on the multiple upper support frames 32 can be lifted and lowered independently, so as to adjust the horizontality of the pressure vessel 1 and ensure that the axial direction of the pressure vessel 1 is completely parallel to the axial direction of the lower support frame 31, thereby ensuring the verticality of the pressure vessel 1.

[0043] Optionally, the lower support frame 31 and the upper support frame 32 are integrally arranged, the lower support frame 31 is a cage-shaped steel welded structure, and the upper support frame 32 is also a steel welded structure, so that the structure has good strength and is convenient for supporting the reactor core module. More specifically, a ring-shaped walkway 312 is also provided on the lower support frame 31 to facilitate workers to walk on it.

[0044] Optionally, see Figure 3 and Figure 4 The pressure vessel 1 is cylindrical, and a plurality of evaporators 2 are arranged, and the plurality of evaporators 2 are arranged around the axis of the pressure vessel 1; the vertical packaging and transportation device for the reactor core module also includes an anti-movement structure 4, and the anti-movement structure 4 includes a mounting bracket 41 and a plurality of anti-movement blocks 42. The mounting bracket 41 is cylindrical, and the mounting bracket 41 is used to be placed in the pressure vessel 1 and to be connected to the inner wall of the pressure vessel 1. The plurality of anti-movement blocks 42 are arranged around the axis of the mounting bracket 41 on the peripheral side of the mounting bracket 41. The plurality of anti-movement blocks 42 are used to extend between two different adjacent evaporators 2 respectively, and the anti-movement blocks 42 along the two circumferential side surfaces of the mounting bracket 41 are used to respectively abut against the two evaporators 2.

[0045] Please note that, please refer to Figure 5 The evaporator 2 is usually in the shape of a plate perpendicular to the circumference of the pressure vessel 1 , and the distance between two adjacent evaporators 2 gradually decreases in the direction toward the axis of the pressure vessel 1 .

[0046] In this embodiment, the two side surfaces of the anti-movement block 42 along the circumference of the mounting bracket 41 are used to respectively abut the two evaporators 2. In this way, when the anti-movement structure 4 is installed to the pressure vessel 1, the anti-movement block 42 can be made to abut the two adjacent evaporators 2 along the two side surfaces of the circumference of the mounting bracket 41, thereby limiting the distance between the two evaporators 2 and achieving the effect of preventing the evaporator 2 from circumferentially moving during transportation.

[0047] Optionally, see Figure 6A support rod 411 extending up and down is provided at the lower part of the peripheral side of the mounting bracket 41, and a fixing block 412 is provided at the upper end of the support rod 411. The fixing block 412 is provided with two first screw holes extending along the radial direction of the mounting bracket 41, and the two first screw holes are spaced apart from each other, and an adjusting screw 4121 is respectively passed through the two first screw holes. The anti-movement block 42 is arranged on the outer side of the fixing block 412 away from the mounting bracket 41, and two second screw holes corresponding to the two first screw holes are provided on the anti-movement block 42, and the second screw holes are connected to the ends of the adjusting screw 4121 extending out of the first screw holes.

[0048] In this embodiment, the anti-movement block 42 is indirectly connected to the mounting bracket 41 through the adjusting screw 4121, the fixing block 412 and the support rod 411. Thus, when the two adjusting screws 4121 are simultaneously screwed toward the middle of the mounting bracket 41, the anti-movement block 42 can be driven to move toward the middle of the mounting bracket 41. The side of the anti-movement block 42 is more closely attached to the evaporator 2, and the circumferential anti-movement effect on the evaporator 2 is better.

[0049] Optionally, see Figure 3 , Figure 7 and Figure 8 The inner wall of the pressure vessel 1 is formed with an annular support platform 12, and the annular support platform 12 is located below the multiple evaporators 2; the lower part of the mounting bracket 41 is provided with a plurality of fixing structures 43 arranged in sequence along the circumference of the mounting bracket 41, and the fixing structure 43 includes an upper clamping rod 431 and a lower clamping seat 432 respectively arranged on the mounting bracket 41, and the upper clamping rod 431 and the lower clamping seat 432 are used to jointly clamp the annular support platform 12 so that the mounting bracket 41 is fixed to the inner wall of the pressure vessel 1.

[0050] Specifically, the upper clamping rod 431 and the lower clamping seat 432 can be detachably connected to the mounting bracket 41 by bolt connection. The process of installing the upper clamping rod 431 and the lower clamping seat 432 to the mounting bracket 41 can enable the upper clamping rod 431 and the lower clamping seat 432 to clamp the annular support platform 12 together.

[0051] In this embodiment, the mounting bracket 41 is fixed to the inner wall of the pressure vessel 1 by clamping, which has good clamping force and is easy to assemble and disassemble.

[0052] Optionally, see Figures 3 to 5The anti-movement structure 4 also includes a plurality of upper tightening blocks 44, which are sequentially arranged around the circumference of the mounting bracket 41 on the circumferential side of the upper portion of the mounting bracket 41. One end of the upper tightening block 44 close to the mounting bracket 41 is screwed with a first tightening screw 441 extending radially along the mounting bracket 41, and one end of the first tightening screw 441 away from the upper tightening block 44 is screwed with the mounting bracket 41. The upper tightening block 44 is used to move toward the inner wall of the pressure vessel 1 when the first tightening screw 441 rotates, so as to be tightened to the inner wall of the pressure vessel 1.

[0053] In this embodiment, multiple upper tightening blocks 44 can be used to tighten the upper part of the inner wall of the pressure vessel 1. In this way, after the upper clamping rod 431 and the lower clamping seat 432 clamp the annular support platform 12, the first tightening screw 441 can be screwed toward the inner wall of the pressure vessel 1, so that the multiple upper tightening blocks 44 can jointly tighten the upper part of the inner wall of the pressure vessel 1, further preventing the mounting bracket 41 from circumferentially moving relative to the pressure vessel 1.

[0054] Optionally, see Figure 3 and Fig. 9 The anti-movement structure 4 also includes a plurality of lower tightening blocks 45, which are sequentially arranged around the circumference of the mounting bracket 41 on the circumferential side of the lower portion of the mounting bracket 41. One end of the lower tightening block 45 close to the mounting bracket 41 is screwed with a second tightening screw 451 extending radially along the mounting bracket 41, and one end of the second tightening screw 451 away from the lower tightening block 45 is screwed with the mounting bracket 41. The lower tightening block 45 is used to move toward the inner wall of the pressure vessel 1 when the second tightening screw 451 rotates, so as to be tightened to the inner wall of the pressure vessel 1.

[0055] In this embodiment, multiple lower tightening blocks 45 can be used to tighten the lower part of the inner wall of the pressure vessel 1. In this way, after the upper clamping rod 431 and the lower clamping seat 432 clamp the annular support platform 12, the second tightening screw 451 can be screwed toward the inner wall of the pressure vessel 1, so that the multiple lower tightening blocks 45 can jointly tighten the lower part of the inner wall of the pressure vessel 1, further preventing the mounting bracket 41 from circumferentially moving relative to the pressure vessel 1.

[0057] In this embodiment, a plurality of compression screws 46 may be used to compress the suspension frame 13 to prevent the suspension frame 13 from axially vibrating relative to the pressure vessel 1, thereby achieving axial fixation of the evaporator 2 and preventing the evaporator 2 from axially moving.
