Embodiment 1

[0029] Embodiment 1: The liquid helium leakage monitoring and alarm module can be longitudinally arranged at the top, so that there is no need to open a top monitoring and fixing groove for installing the helium sensor module 5 on the inner top surface of the arc guide chute 2, and the normal state The lower centrifugal cooling fan 9 is started, and the heat on both sides of the nuclear magnetic equipment 1 is extracted to improve the heat dissipation of the equipment. Once the helium gas is detected, the centrifugal cooling fan 9 is turned off, and then the arc adjustment block 11 drives the external assembly frame 3 along the nuclear magnetic field. The periphery of device 1 is turned over to accurately locate the leak location;

Embodiment 2

Embodiment 2: The liquid helium leak monitoring and alarm module can be used to be laterally arranged at the lowermost end, and the helium sensor module 5 on the top surface of the arc-shaped guide chute 2 can be used to monitor the leaked helium. The motor 4 and the centrifugal cooling fan 9 are started. At this time, the arc-shaped adjustment block 11 drives the outer assembly frame 3 to turn over along the periphery of the nuclear magnetic apparatus 1 to accurately locate the leakage position.

[0030] Further, in order to cooperate with the bottom limit, the arcuate inner surface of the arcuate adjustment block 11 is provided with a side arcuate transmission groove 27 with a built-in guide roller 26 .

[0031] Further, in order to cooperate to reduce the frictional force of the bottom transmission, the inner walls on both sides of the arc-shaped transmission groove 27 on the bottom side are elastically equipped with lateral extrusion frames 28 for installing the guide roller...

Abstract

The invention relates to the technical field of nuclear magnetic helium monitoring auxiliary equipment, in particular to a conveying device of a monitoring alarm module for monitoring nuclear magnetic liquid helium leakage, which comprises nuclear magnetic equipment, an arc-shaped guide chute, an external assembly frame, an adjusting motor, a helium sensor module, an electric control switch, a buzzer, an LED warning lamp and a centrifugal cooling fan. The conveying device of the monitoring and alarming module for monitoring nuclear magnetic liquid helium leakage comprises an arc-shaped guide sliding groove and an arc-shaped adjusting block which are symmetrically formed, the arc-shaped adjusting block is controlled by an adjusting motor to move in the arc-shaped guide sliding groove, and a helium sensor module located on the inner top face of the arc-shaped guide sliding groove is matched; operation can be automatically started and a leakage point can be warned when liquid helium leaks, the control mode is very simple and efficient, and monitoring is very accurate; the conveying device is composed of an arc-shaped adjusting block located in an arc-shaped guide sliding groove and an external assembly frame located on the periphery of the nuclear magnetic equipment in a split mode, disassembly and assembly are convenient, and later maintenance and use are facilitated.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic helium monitoring auxiliary equipment, in particular to a conveying device for monitoring a nuclear magnetic liquid helium leakage monitoring and alarm module. Background technique [0002] Nuclear magnetic resonance is a physical process in which the spin energy level of an atomic nucleus with a non-zero magnetic moment undergoes Zeeman splitting and resonance absorbs a certain frequency of radio frequency radiation. Nuclear magnetic resonance spectroscopy is a branch of spectroscopy, its resonance frequency is in the radio frequency band, and the corresponding transition is the transition of the nuclear spin at the nuclear Zeeman level. [0003] MRI examination has become a common imaging examination method. As a new type of imaging examination technology, MRI will not affect human health, but six types of people are not suitable for MRI examination, namely: installation of cardiac paci...
