Description

It is a kind of that one can adjust vertical water acquisition method
Technical field
The invention belongs to acquisition technique field, and in particular to a kind of one can adjust vertical water acquisition method.
Background technology
Seawater sampling is the most conventional investigation content of ocean relevant speciality, and analyzing the indices in seawater is research and opens Send out the important channel of ocean.Generally, it would be desirable to gather different water levels seawater.However, common hydrophore quality very little itself, holds Easy feeling the current so that hydrophore can not vertical subsidence to certain depth, bring certain error to experiment.Researcher must not Do not find weight in addition to tie up on hydrophore, but weight is difficult to fix, the Probability maximum of landing.Also, different water depth is to adopting Hydrophone quality requirement is different, and inconvenience is brought to experiment.It is right and conventional rose formula hydrophore is equipped with winch due to needing Ship's condition requires very high, therefore develops a kind of monomer-type new vertical hydrophore and seem very necessary, and this method is for one Different water levels water acquisition operation is significant.
The content of the invention
It is an object of the invention to provide a kind of feeling the current is small, the water acquisition degree of accuracy is high, and one of water acquisition efficiency high can Vertical water acquisition method is adjusted, water sampling device can change total quality, not only may be used with change in depth used by above-mentioned water acquisition method Ensure the vertical drop of hydrophore, improve the water acquisition degree of accuracy, can also reduce the requirement of the equipment to operating personnel and water acquisition outfit, Reduce the cost of water acquisition operation.
The present invention is for the scheme taken of solution above-mentioned technical problem:A kind of one can adjust vertical water acquisition method, adopt Water method is:Water sampling device is submerged under water, control water tank gradually sucks water body during water sampling device decline;When water acquisition fills Put after reaching designated depth, hydrophore carries out water acquisition;After water acquisition, rope recovery, water sampling device rises, during rising Control water tank gradually discharges water body;Water sampling device rises to the water surface, completes water acquisition;The pipe clamp that the outlet pipe of control hydrophore accompanies takes Go out sample water body.Hydrophore uses the global design of lighter weight, is easy to one man operation;Water tank has counterweight effect, fixation side It can lean on, and with water depth ratio adjustable weight quality, coordinate hydrophore to use, can not only reduce and operating personnel and water acquisition are matched somebody with somebody The requirement of standby equipment, the efficiency when shoaling layer gathers can be also improved, reduce the cost of water acquisition operation;Pipe clamp picks and places just Victory, small to outlet pipe damage, the effect for obstructing water is good.Above-mentioned water acquisition method is easy to operate, and feeling the current is small, the water acquisition degree of accuracy Height, and equipment volume is small, it is easy to operate, gather industry for water body and great convenience is provided.
To optimize above-mentioned technical proposal, the measure taken also includes:Water sampling device includes fixed mount, and fixed mount is by fixing Ring and fix bar composition, fixed mount front end are fixed with hydrophore by retainer ring, and fixed mount rear end is fixed with control by retainer ring Case processed, water tank is fixed with by retainer ring at left and right sides of fixed mount, fix bar is connected ring two-by-two.Fixed mount is fixed reliably, And the distribution of weight of tunable single unit system, the fixed form of above-mentioned hydrophore, water tank and control cabinet so that water sampling device is overall It can effectively keep balancing, to ensure the normal work of hydrophore.

Embodiment 4:
Using the water sampling device described in embodiment 2 and water acquisition method, with existing pressed cover hydrophore, buy in Beijing Pu Lite Instrument Ltd. carries out contrast experiment, sets the water sampling device of embodiment 2 as experimental group, and existing pressed cover hydrophore is control Group.
Zhoushan Dinghai to Pan Zhi islands Its Adjacent Waters are taken in experiment place, and sample water acquisition target depth is 65m, wave during experiment Suitably, seawater flowing in waters is suitable, and experiment is divided into two groups, sets target before experiment in target marine site, fixes vertically and horizontally Line, and scale is carried, two groups of hydrophores are submerged in water simultaneously during experiment every time, two groups of hydrophore lowered positions are close, seawater Mobility status is close, and the position of two groups of hydrophores is arranged in same level for vertical seawater flow direction, two groups of hydrophores Rope is used, three groups of experiments is carried out, 10 water acquisition operations of every group of carry out, calculates average horizontal offset amount, be recorded in following table.
It can be obtained by upper table data, the horizontal offset of hydrophore of the invention is much smaller than existing hydrophore, and of the invention adopts Hydrophone feeling the current is small, and water acquisition operation hour offset is few, and the degree of accuracy of institute's water acquisition is high, has bigger prospect of the application.
The water space 13 of water tank 3 can store dress water body be not limited only to 5 ~ 10kg, should also include 5kg or 5.1kg or 5.2kg or 5.3kg or 5.4kg ... or 9.9kg or 10kg.
The central angle angle of the arc of arc side groove 124 is not limited only to 23 ~ 31 °, should also include 23 ° or 23.1 ° or 23.2 ° or 23.3 ° or 23.4 ° ... or 30.9 ° or 31 °.
The prior art of routine techniques dawn known to those skilled in the art in the present embodiment, is not chatted in detail herein State.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, the ordinary skill people of this area Member, without departing from the spirit and scope of the present invention, it can also make a variety of changes and modification.Therefore, it is all equivalent Technical scheme fall within scope of the invention, scope of patent protection of the invention should be defined by the claims.
