[0002] The steam generators, pressurizers and other main equipment in the nuclear island are all large and large, so the metal reflective insulation blocks used for their insulation are large in size and heavy in weight. During the construction stage, after the metal reflective insulation blocks of the main equipment are installed, they need to go through cold test, pre-service inspection, hot test, and post-hot test inspection. These processes require the metal reflective insulation blocks to be repeatedly dismantled, temporarily stored, and reinstalled. During the operation stage, the metal reflective insulation blocks also need to be dismantled, temporarily stored, and reinstalled to conduct in-service inspections of the operating status of the main equipment and ensure the safe operation of the nuclear power plant. The metal reflective insulation blocks of the main equipment are mostly rectangular plate structures with a slight curvature. When installing the insulation blocks, the circumferential and longitudinal overlap longitudinal seams are staggered. This installation method, coupled with factors such as thermal expansion, has caused great difficulties in the disassembly, assembly, and transportation of the metal reflective insulation blocks.

[0003] Therefore, the prior art still needs to be improved. Summary of the invention

[0004] The purpose of the invention is to solve the problem that the existing thermal insulation blocks have no good fulcrum during disassembly, assembly and transportation, which makes disassembly, assembly and transportation difficult and leads to low efficiency in disassembly, assembly and transportation.
