Modularized detachable probe plate device used under strong magnetic field condition

Abstract

The invention discloses a modularized detachable probe plate device used under a strong magnetic field condition. The modularized detachable probe plate device comprises a square structure formed by connecting a probe assembly and a connecting assembly, the probe assembly comprises a plurality of probes, the probes sequentially penetrate through a nut of a fastening bolt, a compression spring in a screw rod, a stop block and an insulating plate and are assembled together through threads, the other end of each probe is sleeved with a probe head protection device, and the probe head protection device is vertically embedded in the side, close to a tested piece, of the insulating plate; the connecting assembly comprises a connecting main rod, and the connecting main rod penetrates through the base plate, the insulating plate and the fastener short plate and is fastened through a nut; according to the invention, the position of the nut can be flexibly adjusted according to the size of the measured flow channel, so that the insulating plate is well attached to the wall surface of the flow channel, and the probe head is in contact with the wall surface of the flow channel to measure parameters such as potential / temperature; the invention has the advantages that the probe array is easy to replace, the probes are in good contact with a test element, the probe head is not easy to damage, the whole insulating plate is convenient to install, and the insulating plate adapts to rectangular channels with different sizes.

Description

technical field [0001] The invention belongs to the technical field of fluid flow and heat exchange measurement, in particular to a modular detachable probe card device used under the condition of strong magnetic field. Background technique [0002] With the gradual depletion of fossil energy, energy issues have always been the focus of attention around the world, and it is also one of the important factors hindering my country's economic and technological development. Developing an alternative new energy source is the fundamental way to solve the energy crisis. As an efficient energy source, nuclear energy has very important application prospects. Nuclear fission technology has been successfully used for commercial power generation after decades of development, but its reaction process has certain safety hazards, and the nuclear waste generated may cause long-term damage to the natural environment. Nuclear fusion is different. It has the advantages of being clean, environ...
