Description
Technical field
The present invention relates to a kind of seawater to monitor sampling method, more specifically, it relates to which a kind of monitored using sampler
The method of construction sea area concentration of suspension.
Background technique
Currently, needing periodically to be sampled the concentration of suspension in the region seawater in construction sea area operation process
Detection, traditional seawater sampling mode is that directly sample bucket is thrown into seawater, and drawstring hauls sample bucket and carries out seawater sampling, is taken
Sample barreled lifts sample bucket after expiring seawater.This sampling mode is easy to operate, but the water layer where the seawater being sampled to is
It is uncertain, it may be possible to water surface site, it is also possible to which that position in water, seawater sampling limitation is larger, can not accurate measurements
The concentration of suspension of certain depth position in seawater.
Summary of the invention
The present invention overcomes cannot achieve certain depth position when construction sea area carries out the sampling of water suspension concentration monitor
The deficiency of the sampling operation of seawater provides a kind of method for monitoring construction sea area concentration of suspension using sampler, its energy
The sampling operation of construction sea area certain depth position seawater is realized, convenient for the suspension of accurate measurements construction sea area certain depth position
Object concentration.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme: a kind of utilize sampler monitoring construction
The method of sea area concentration of suspension, sampler include the positioning column that can be stretched up and down, are removably mounted at taking on positioning column
Sample pipe, probe tube lower end are equipped with the water storage section of U-shaped, the inlet segment of vertical straight line style are connected in water storage section, and inlet segment is opening down,
Inlet segment open end connects limited cover, and inlet segment inner wall is equipped with installation bulge loop, installs and is tightly connected water-separating film on bulge loop, intakes
Several water inlet side openings, an influent side hole site articulated linkage are equipped on section side wall between water-separating film and limited cover, connecting rod front end connects
Stamp needle is connect, rod rear end stretches out inlet segment and end connects push plate, and retaining spring is connected between connecting rod front end and limited cover, stabs needle
Tip close to water-separating film be arranged；When construction sea area carries out seawater sampling, the length of positioning column is first adjusted, then positioning column is inserted into
The bottom is fixed, and probe tube upper end is exposed the surface, and the mechanical gripper of construction operation touches in carrying out work progress to be pushed away
In the plate water impact to push plate upper surface that perhaps connecting rod or mechanical gripper work progress generate, connecting rod is driven to turn clockwise
Dynamic, stamp needle, which moves up, pokes water-separating film, and seawater is flowed into inlet segment, water storage section and probe tube from water inlet side opening, and one section
Probe tube is pulled up after time, if it find that having got seawater in probe tube, entire sampler is directly pulled out into sea
Sampling can be completed in water；If it find that not getting seawater in probe tube, probe tube is pushed down on and continues to sample, until discovery
Until probe tube gets seawater.
When construction sea area carries out dredging operation, seawater sampling monitoring concentration of suspension is periodically carried out, first monitoring as needed
Sea water advanced adjustment positioning column length, then by positioning column insertion the bottom be fixed, probe tube upper end is exposed the surface, construction
