The Canada SNO neutrino detector adopts a rope suspension supporting structure, and a plurality of synthetic fiber ropes fixed at the equator suspend the organic glass sphere in the air [1] . The patent ZL201410088815.X provides an equatorial flexible supporting structure of an organic glass detector, which realizes flexible support between a sphere and the supporting structure, can effectively disperse pressure and is beneficial to absorbing seismic energy.
However, the support mode of the sonde in SNO in Canada has high requirements on rope strength, and is only applicable to the detector with smaller sphere diameter. The support column type supporting structure and the equatorial flexible supporting structure are generally fixedly supported, and in the installation process, the phenomena of poor positioning, structural deformation and stress concentration caused by manufacturing deviation are often caused, so that the reliability of the structure is greatly reduced. The equator of patent zl201410088815.X is a metal ring, its shading rate is high, reduces the accuracy of neutrino detection to a certain extent.
