High-level liquid waste sampling rod for accurate sampling based on servo control

Abstract

The invention discloses a high-level liquid waste sampling rod for accurate sampling based on servo control, which comprises a sampling working box. The upper end of the sampling working box is provided with a fixing seat and a mounting seat; the upper end of the fixing seat is provided with a hanging rod positioning pulling rope displacement sensor; the upper end of the mounting seat is providedwith an electric servo lifting device; the upper end of the sampling working box is provided with a pulling rope sensor wire rope, a wire rope A and a wire rope B; a hanging rod module unit is arranged on the sampling working box; and the front end of the hanging rod module unit is provided with a snap-on quick change mechanical interface device and a sampler. The sampler arranged in the high-level liquid waste sampling rod for accurate sampling based on servo control performs sampling of each layer of an organic phase, a clear liquid phase and a mud phase for quantitative accurate sampling; due to the pulling rope sensor wire rope and the hanging rod positioning pulling rope displacement sensor, real-time position monitoring is realized and accurate sampling is controlled; and the whole structure is stable, a sampling point is positioned accurately, and the sampling amount is accurate.

Description

technical field [0001] The invention relates to the technical field of storage, detection and sampling of nuclear waste liquid in the field of nuclear industry, in particular to a high-level waste liquid sampling rod for precise sampling based on servo control. Background technique [0002] With the reserve and long-term development of nuclear industry automation technology, it is necessary to regularly sample and analyze the high-level liquid in the storage tank during the storage process of nuclear industry high-level waste liquid. The problem of imprecision. Due to the high pollution resistance of the sampling samples, the amount of samples used for analysis needs to be strictly controlled. Too much sampling will increase the radiation dose. Therefore, a high-level radioactive waste based on precise sampling based on servo control is required. The liquid sampling rod makes the positioning of the sampling point accurate and the sampling volume accurate. SUMMARY OF THE IN...
