Description
Technical field
The utility model relates to Weight by Draft and measures accessory with the port water-mass density, specifically, relates to a kind of port water sample device.
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.
The utility model content
The purpose of the utility model is to provide a kind of port water sample device, can not thousand gets 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 utility model 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 principle of work of the utility model 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.
The beneficial effect of the utility model is: simple in structure, easy to use, sample standard, efficient, avoided conscientiously causing dispute therefrom and dispute.

Among the figure: 1, cylindrical shell; 2, cover cap; 3, inner cap; 31, integrated disc portions; 32, boss; 4, operation rope; 5, rubber gasket; 6, three square rings; 7, suspension ring; 8, rubber gasket.
Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
As shown in Figure 1; The port water sample device of the utility model embodiment, its monnolithic case is cylindrical, comprises cylindrical shell 1, cover cap 2, inner cap 3 and operation rope 4; Said cylindrical shell 1 one end openings, end sealing; Said cover cap 2 screws the openend at said cylindrical shell 1, and its center offers the through hole of a regular shape, and said inner cap 3 comprises that at least one can be with the integrated disc portions 31 of the through hole shutoff of said regular shape; The diameter of said integrated disc portions 31 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 1, the center of said inner cap 2 is provided with one, and to be used to be the structure of said operation rope 4, and be arranged in the said cylindrical shell 1 through the operation rope 4 that is on it and passes the through hole of said regular shape.
For playing sealing and buffering effect, guarantee the standard of the port water sample of adopting, and avoid the bump of inner cap and cover cap when proposing operation and restrict that preferably, said port water sample device also comprises the rubber gasket 5 that is arranged on said cover cap 2 inner tops.
Preferably, the through hole of the regular shape offered of said cover cap 2 centers is a circular hole.
Preferably; It is that the structure of operating rope 4 comprises boss 32 and three square rings 6 that are raised in said integrated disc portions 31 surfaces that said inner cap 3 centers are used to; Offer the through hole of horizontal direction on the said boss 32, said through hole is provided with three square rings 6, and said operation rope 4 ties up on said three square rings 6.
For preventing to get rusty, keep long as far as possible serviceable life, preferably, said cylindrical shell 1, cover cap 2 and inner cap 3 are processed by stainless steel material.
For ease of suspension, preferably, the outside surface of said cylindrical shell 1 is provided with suspension ring 7.
