Description

Sleeve type supporting structure of organic glass detector

Technical Field

Background

The organic glass has the advantages of high light transmittance, light weight, high mechanical strength, heat resistance, aging resistance and the like, and is widely used as a main body material of the neuter detector. 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.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1-4, the sleeve type supporting structure of the organic glass detector is used for supporting organic glass spheres of the organic glass detector on a wall body 2; the organic glass sphere 1 has an equatorial slab 7, the diameter of which is 2 meters to 40 meters; the telescopic support structure comprises: the metal sleeve 3, the pressing plate 4, the supporting rod 5 and the rubber gasket 6; wherein, a plurality of holes which are uniformly distributed and matched with the supporting rods 5 (the number of the supporting rods can be appropriately increased or decreased according to the size of the ball) are formed on the equatorial thick plate 7, one end of the supporting rods 5 is placed in the holes, a rubber gasket 6 is arranged between the holes and the supporting rods 5, the rubber gasket 6 has certain elasticity, can buffer and absorb earthquake energy, and improves the safety and reliability of the structure; the other end of the supporting rod 5 is embedded into a metal sleeve 3; the metal pipe 3 is fixed into the wall 2 by the pressure plate 4 through bolts 8.

The invention has simple assembly process, no complex operations such as welding and the like are needed on site, and the supporting rod 5 is connected with the organic glass sphere equatorial thick plate 7 and the metal sleeve 3 in a nested mode. The supporting rods 5 corresponding to the two ends of each diameter are in a group, and each group is installed in turn according to the clockwise (or anticlockwise). The pressing plate 4 does not fix the metal sleeve 3 in advance, but is fixed in sequence by the bolts 8 after the supporting rod 5 and the metal sleeve 3 are positioned. The support rod 5 can generate certain displacement along the axial direction of the sleeve 3, and the pressing plate 4 is provided with oblong bolt holes 9 (the number of the bolts on the pressing plate can be appropriately increased or decreased according to the size of the organic glass ball), and the metal sleeve 3 can also generate certain circumferential displacement, so that the stress of the support structure and the organic glass ball 1 under the change of temperature and load is relieved.
