Embodiment Construction

[0027] In order to make the purpose, specific solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] figure 1 The Dewar 1 in it is the object that needs to be stabilized in all directions without power in the present invention. Its shape is a cylinder, and it is the working platform of the superconducting quantum interferometer. It must be equipped with liquid helium or liquid nitrogen during normal operation. The lower part 12 of the incomplete sphere and the upper part 15 of the incomplete sphere are connected as a whole by the fixing bolt 13 of the incomplete sphere——the incomplete sphere 17, which fixes the Dewar 1 through frictional force and acts as a part of the Dewar 1. Universal stabilizer. The top 3 of the non-closed spherical cabin and the bottom 8 of the non-closed spherical cabin are connected as a...

Abstract

The invention relates to an unpowered method for achieving dewar universal stability and a corresponding device. The unpowered method is characterized in that 1 state changing is impeded by aid of torque formed by offset of gravity centers of a dewar and a carrier of the dewar on the basis of the idea of stabilizing after vibration attenuation, fluid is guided in to control the return torque to be dynamically increased, and system stability is adjusted by combining graded damping coefficients; and 2 a similar concentric sphere structures are adopted, the dewar is fixed in an interior sphere, all the spheres are connected with a non-sealed spherical cabin through asymmetrically distributed rolling pulleys, rotating of the interior sphere is controlled by gravity and transformation power of gravity, and therefore dewar universal stability in the moving state is achieved in an unpowered mode. The unpowered method can effectively improve the response speed of a stabilization device and weakens and even eliminates vibration generated in the stabilization process. The unpowered method and the corresponding device are simple to achieve and low in cost.

Description

technical field [0001] The invention relates to a non-powered method and a corresponding device for realizing universal stability of a Dewar, in particular to a method and a corresponding device for realizing universal stability by using the self-gravity of a Dewar and its auxiliary equipment in a flight state. It belongs to the field of mechanical transmission. Background technique [0002] Superconducting Quantum Interference Device (SQUID: Superconducting QUantum Interference Device) is currently the most sensitive magnetic sensor known, and it has been used in many applications in static working environments. The magnetic line of force can easily cause its high-sensitivity readout circuit to overflow due to insufficient range or lose lock due to insufficient slew rate. For example, the measurement resolution is 100fT, and the earth’s magnetic field is generally tens of uT. When the fluctuation range is 10uT , The dynamic range is 160dB, which is almost impossible to ach...
