Brief description
Below in conjunction with the accompanying drawings the utility model is further illustrated
Fig. 1 is the structural representation of guider described in the utility model；
Specific embodiment
Explanation and specific embodiment are further described to the utility model below in conjunction with the accompanying drawings：
Embodiment 1
As shown in figure 1, the fuel rod guider of bracket repaired by a kind of nuclear power fuel assembly, the guiding including strip is fixed
Position plate 1, a upper lateral part of guide positioning plate 1 is provided with device for pre-positioning 8, and other side is provided with sleeve 9, guide positioning plate 1
Middle lower portion be fixed with multiple positioning and have strong market potential 2, in the present embodiment, have strong market potential 2 quantity of positioning is 24, and 24 positioning are had strong market potential
Distribution corresponding with the lead in fuel assembly.
It is provided with operation pin 7, the bottom of sleeve 9 is provided with perforate, steady pin 6 is screwed into operation pin 7 through perforate in sleeve 9
Bottom by operate pin 7 be fastened in sleeve 9.
Sleeve 9 is provided with operation pin device for pre-positioning 3, operation pin device for pre-positioning 3 in the side away from guide positioning plate 1
Top be provided with upper padding plate 5, the bottom of operation pin device for pre-positioning 3 is provided with lower bolster 4, by stay bolt by upper padding plate 5
It is fixed on operation pin device for pre-positioning 3 with lower bolster 4.
When carrying out nuclear power fuel assembly reparation and changing, by positioning have strong market potential 2 be inserted into fixing in the lead of fuel assembly,
Thus nuclear power fuel assembly is repaired bracket positioning with fuel assembly, and then the replacing of fuel assembly can be carried out.
It will be recognized by those skilled in the art, on the premise of without departing from protection scope of the present invention, can be to above-mentioned
Embodiment carries out various modifications, change and combination, and thinks that this modification, change and combination are the models in originality thought
Within enclosing.
