Variable step radioactive aerosol filter paper tape removal mechanism and detection device

Abstract

The application relates to a variable-step radioactive aerosol filter paper tape running mechanism and a detection device, which comprises a mounting bracket, one side of the mounting bracket is provided with a running auxiliary adjusting mechanism, and one side of the mounting bracket is provided with a detection device body; in the application, the winding action of the filter paper tape body is driven through a stepping motor, and a transmission shaft, a winding rod and a speed-adjustable control system are matched, so that fine control of a sampling interval is realized, the radioactive aerosol collection requirements of different intensities or periods are adapted, compared with a traditional fixed-distance running paper structure, the step distance can be flexibly set according to actual working conditions, the use efficiency of the filter paper is improved, the response capability of a monitoring system to sudden radioactive events is enhanced, meanwhile, the coordinated arrangement between the running mechanism and the detection device body avoids error accumulation, realizes closed-loop control of a sampling and detection process, and helps to improve the precision and practicability of the whole device.
