Casing pipe type support structure of organic glass detector

Abstract

The invention discloses a casing pipe type support structure of an organic glass detector. The casing pipe type support structure of the organic glass detector is used for supporting an organic glassball body of the organic glass detector on a wall body; and the organic glass ball body is provided with an equator thick plate. The casing pipe type support structure comprises metal casing pipes, pressing plates, support rods and rubber washers, wherein a plurality of uniformly distributed holes matched with the support rods are formed in a circumferential direction of the equator thick plate; one ends of the support rods are put into the holes; the other ends of the support rods stretch into the metal casing pipes; the rubber washers are arranged between the holes in the equator thick plateand the support rods; and the pressing plates fix the metal casing pipes onto a wall body through a plurality of bolts. According to the casing pipe type support structure of the organic glass detector provided by the invention, the occurrence of the phenomena of poor positioning, structure deformation and stress concentration caused by manufacture deviation during an installation process of thedetector is avoided, and the safety and the reliability of the detector are improved. The shading coefficient is reduced, and the neutrino detection precision is improved. The on-site assembly efficiency is improved.

Description

technical field [0001] The invention relates to a detector structure, in particular to a sleeve type support structure of a plexiglass detector. Background technique [0002] Plexiglass has the advantages of high light transmission, light weight, high mechanical strength, heat resistance and aging resistance, and is widely used as the main material of neutrino detectors. The Canadian SNO neutrino detector adopts a rope suspension support structure, and the plexiglass sphere is suspended in the air by several synthetic fiber ropes fixed at the equator [1] . Invention patent ZL201410088815.X proposes an equatorial flexible support structure of a plexiglass detector, which realizes the flexible support between the sphere and the support structure, can effectively disperse pressure, and is conducive to absorbing seismic energy. [0003] However, the support method of the Canadian SNO neutrino detector has high requirements on the strength of the rope, which is only suitable fo...

Problems solved by technology

[0003] However, the support method of the Canadian SNO neutrino detector has high requirements on the strength of the rope, which is only suitable for the detector with a small diameter of the sphere

For pillar support structures and equatorial flexible support structures, the fixed ends are generally fixed supports. During the installation process, poor positioning, structural deformation and stress concentration are often caused by manufacturing deviations, which greatly reduce the reliability of the structure.

The metal ring at the equator of patent ZL201410088815.X has a high shading rate, which reduces the accuracy of neutrino detection to a certain extent
