Description
Technical field
The present invention relates to Weight by Draft and measure accessory, specifically, relate to a kind of port water sample device with the port water-mass density.
Background technology
The cardinal principle of Weight by Draft is " Archimedes' principle ", and promptly the boats and ships displacement of volume multiply by place port water-mass density and equals boats and ships sum total weight.After boats and ships load was invariable, the boats and ships displacement of volume was a fixed value basically.Thereby, meter heavy the port water-mass density value that adopts truly whether, be directly connected to Weight by Draft result's accuracy.Because the port water-mass density of bow and stern and top layer and bottom there are differences, so for recording port water-mass density value comparatively accurately, countries in the world industry technology standard code: skewer is got half place's port water sample of the ship centre board exterior draft degree of depth and is recorded density value in order to Weight by Draft.
In the real work, owing to there is not suitable port water sample device, the overwhelming majority all arbitrarily adopts the 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, 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 sample device, can not thousand get the standard water sample to solve existing port water sample device, thereby can not accurately record the problem of port water-mass density value.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of port water sample device, its monnolithic case is cylindrical, comprises cylindrical shell, cover cap, inner cap and operation rope; Said cylindrical shell one end opening, end sealing; Said cover cap screws the openend at said cylindrical shell, and its center offers the through hole of a regular shape, and said inner cap comprises that at least one can be with the integrated disc portions of the through hole shutoff of said regular shape; The diameter of said integrated disc portions is greater than the maximal value of any distance between two points on the through hole of said regular shape; And less than the internal diameter of said cylindrical shell, the center of said inner cap is provided with one, and to be used to be the structure of said operation rope, and be arranged in the said cylindrical shell through the operation rope that is on it and passes the through hole of said regular shape.
Preferably, said port water sample device also comprises the rubber gasket that is arranged on said cover cap inner top.
Preferably, the through hole of the regular shape offered of said cover cap center is a circular hole.
Preferably; It is that the structure that operation is restricted comprises boss and three square rings that are raised in said integrated disc portions surface that said inner cap center is used to; Offer the through hole of horizontal direction on the said boss, said through hole is provided with three square rings, and said operation rope ties up on said three square rings.
Preferably, said cylindrical shell, cover cap and inner cap are processed by stainless steel material.
Preferably, the outside surface of said cylindrical shell is provided with suspension ring.
Preferably, said interior cover upper surface is provided with rubber gasket.
The present invention also provides the method for application of above-mentioned arbitrary port water sample device, it is characterized in that, comprises the steps:
Steps A: the position of the port water sample device of sealing being inserted first degree of depth in the water;
Step B: make that port water sample device quickens to move downward, because the effect of velocity contrast and hydraulic pressure, cylindrical shell and cover disengage, and port water gets into cylindrical shell via the through hole and the slit between inner cap and cylindrical shell at cover cap center;
Step C:, make its stop motion when port water sample device moves downward second degree of depth to the water;
Step D: make that port water sample device quickens to move upward, inner cap and cover cap resume contacts, thereby are sealed, and port water does not get into port water sample device;
Step e: port water sample device moves up to the position of first degree of depth in the water, makes its stop motion.
Preferably, the degree of depth at said first half place of depth ratio ship draft is high 1 meter; Low 1 meter of the degree of depth at said second half place of depth ratio ship draft.
Preferably, above-mentioned steps A-E is repeated 7-12 time, can water be filled said port water sample device; Preferably, above-mentioned steps A-E is repeated 10 times.
Principle of work of the present invention is: if want to make object to be submerged in naturally in the water, then its gravity must be greater than its suffered buoyancy; The pressure (hydraulic pressure) that the immersion body surface receives increases along with the increase of underwater penetration; Be immersed in the object in the water, its motional inertia size is directly proportional with the quality (weight) of object.
Particularly; Through utilizing port water sample device when the underwater exercise; Slit between hydraulic pressure that the inertia of cylindrical shell and inner cap is poor, inner cap surface receives and inner cap and cylindrical shell, make port water sample device every by speed carry, speed puts once just water inlet once, thereby through speed repeatedly carry, speed puts the operation rope; Port water sample device is moved in the scope of next meter in half place of said draft overflow, just can obtain representative port water sample.
Beneficial effect of the present invention is: simple in structure, easy to use, sample standard, efficient, avoided conscientiously causing dispute therefrom and dispute.
