Feedback signal is sent, driving motor stop motion is made, so that the installation to cladding modular positions, each cladding modular is all made of this
Positioning method ensures positioning accuracy by by the locating piece on shielded layer, and there is no cumulative errors, increases the accurate of positioning
Property, hydraulic cylinder decline is then controlled, so that the support base of cladding modular is supported on pedestal 5, the pipeline in module at this time
With under system manifold to be in charge of (i.e. the external pipe of cladding modular) substantially aligned, and control mechanical arm, realize pipeline
Alignment and positioning, welding robot weld pipeline, then control first gear, second gear and the rotation of third gear,
So that circumferential trolley is withdrawn from from cladding modular bottom；
D, it controls circumferential trolley 4 to return on radial trolley 3 along circular orbit 2, controls radial trolley 3 and return to radial track 1
On starting point, next piece of cladding modular is mounted on circumferential trolley 4, the installation of next piece of cladding modular is carried out；
E, a, b, c and Step d are repeated and radial trolley 3 is then unloaded, by covering until installing second from the bottom piece of cladding modular 3
Mounting portion 6 is mounted in radial track 1, so that covering mounting portion 6 is moved to the installation site of last block cladding modular 3, i.e.,
The pedestal opening position of pedestal 5, then the erecting and welding trolley 7 in radial track 1, makes welding tractor be moved to covering mounting portion
6 outsides, and control mechanical arm and weld the pipeline in covering mounting portion 6 with outer loop pipeline, it is small that welding is then withdrawn from again
Vehicle, then the strut by being mounted between interior external shielding layer are driven by hydraulic stem and are stretched out, and cladding modular are withstood, to be supplied to
Pressure in cladding modular level and vertical direction, so that entire cladding systems are installed；
Dismantle cladding modular:
Disassembly cladding modular with covering module process is installed on the contrary, f, first removing last block cladding modular of installation, i.e., first
So that welding tractor is moved to 6 outside of covering mounting portion and passes through mechanical arm for the pipeline and outer loop on covering mounting portion 6
Pipe cutting is opened, and covering mounting portion 6 is then made to be moved to the outermost end of radial guidance, and covering mounting portion 6 is unloaded, then passes through
The radial trolley 3 for being equipped with circumferential trolley 4 is mounted in radial track 1；Fission when cladding modular is dismantled, in cladding modular
Product can continue decay heating, be that the module temperature in disassembly process constantly rises, generate some security risks, and will increase
Difficulty is dismantled, therefore, when dismantling cladding modular, after closing the valve of cladding modular and total pipeline, cladding modular preserved pipeline
It is connect with the preserved pipeline on the water tank on circumferential trolley, water enters inside cladding modular to cladding modular in water pump driving water tank
Circulating cooling after circumferential trolley transports module disassembly, extracts tank hot water out and injects cold water and do standard to dismantle next module
It is standby.Cooling water tank in a rectangular parallelepiped shape, and is mounted on the circumferential trolley back side, and water tank stretches out two preserved pipelines.
G, radial trolley 3 is moved to the position of pedestal opening 501, in 4 to every piece cladding modular of mobile circumferential trolley
Lower section, control hydraulic cylinder jack up on cladding modular, then mobile circumferential trolley 4 to radial trolley (3), and mobile radial direction trolley 3 arrives diameter
To the outer end of track 1, cladding modular 8 is removed；
H, g step is repeated, cladding modular is all removed.
To sum up, Fusion-fission covering refuelling system and its material-changing method of the invention overcome little module manifold complicated, flow resistance
Greatly, heat exchange efficiency is low, and assembly work amount is big, and soldering reliability is low and low efficiency of reloading, the disadvantage of process of reloading complexity；Reduce
Tube fluid resistance, increases the flow of single cladding modular, and it is subcritical to improve Z constriction driving fusion-fission hybrid reactor
The heat-exchange capacity of energy covering；The installation difficulty for reducing cladding modular is conducive to the maintenance in later period, safeguards and reload.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
