Inertial differential unlocking spring impact type collector of bottom sediment sample

Abstract

The invention relates to an inertial differential unlocking spring impact type collector of a bottom sediment sample. The inertial differential unlocking spring impact type collector comprises an outer frame device, a nozzle sampling device, a spring impact device and an inertial differential unlocking device. According to the inertial differential unlocking spring impact type collector, the structural design of a chained inertial differential unlocking-spring impact device is utilized, so as to realize the purpose of collecting the bottom sediment sample in the condition of no extraneous source power, and on the basis of an elastic principle, the bottom sediment sample can be instantaneously collected, so as to avoid water erosion. According to the inertial differential unlocking spring impact type collector, the problem that an existing underwater sampling device has difficulty in considering the sampling representativeness and the adaptability to different bottom sediment samples on the basis that destructive sampling is reduced as far as possible can be solved. The inertial differential unlocking spring impact type collector can adapt to different water depth and current conditions and has the advantages of strong reliability and simplicity and convenience in maintenance; if the inertial differential unlocking spring impact type collector can be made into an array and is integrated with automatic lifting machinery, the purpose of quickly collecting bottom sediment samples in different positions with high throughput can be realized.

Description

technical field [0001] The invention relates to an underwater sediment sample collector, in particular to an inertia differential unlocking spring impact type underwater sediment sample collector. Background technique [0002] In the field of environmental monitoring, sampling and evidence collection of underwater sediments (such as solid waste illegally dumped into rivers) is used to study the pollution of underwater sediments; in the field of cultural relics exploration, sampling of underwater mud layers is combined with isotope identification methods The age of ancient relics needs to have a convenient, effective, reliable, wide-ranging and easy-to-maintain underwater sediment sample sampling device, so that samples such as underwater sediment can be quickly and effectively collected at the lowest cost for subsequent use. laboratory analysis. [0003] At present, bucket-type excavation equipment is mainly used in the above-mentioned fields. Most of these equipment are no...
