Description
Technical field
The present invention relates to Weight by Draft and measure accessory with port water-mass density, specifically, relate to a kind of port water sampling sharp-pointed tube.
Background technology
The cardinal principle of Weight by Draft is " Archimedes' principle ", and ship displacement volume is multiplied by port, place water-mass density and equals boats and ships sum totals weight.After boats and ships load is invariable, ship displacement volume is a fixed value substantially.Thereby, meter heavy the port water-mass density value that adopts truly whether, be directly connected to the accuracy of Weight by Draft result.Because the port water-mass density of bow and stern and top layer and bottom there are differences, therefore for recording port water-mass density value comparatively accurately, countries in the world Technical specifications regulation: skewer is got half place's port water sample of the ship centre board exterior draft degree of depth and recorded density value in order to Weight by Draft.
In real work, owing to there is no applicable port water sampling sharp-pointed tube, the overwhelming majority all arbitrarily adopts bucket skewer to get harbor surface water and records density value in order to Weight by Draft.This way lack of standardization, often causes the dispute of relevant party, and even each sticks to his own view, deadlocks and delay the quality time.
Summary of the invention
The object of the present invention is to provide a kind of port water sampling sharp-pointed tube, can not the accurate water sample of thousand label taking to solve existing port water sampling device, thus can not accurately record the problem of port water-mass density value.
For reaching this object, the present invention by the following technical solutions:
