Abstract
A kind of double water law solid density measuring device, container A including a built-in water, the container B of built-in identical water is suspended with the water of container A, the upper surface area of container B reclaimed water is equal with the upper surface area of container A reclaimed water, it is equipped with range unit respectively in the water of container A and container B, range unit connects with data processing and display module.Advantage with the measurement device density of solid is, simple to operate, is not required to artificial calculating and can obtain density of solid value, and is shown；The device can be made compact conformation, Density Measuring Instrument with low cost, for laboratory or jewelry row to noble metal and the Fast nondestructive evaluation of bijouterie article.
Description
Technical field
The utility model is related to object density to measure, and particularly a kind of double water law of utilization Archimedes principle design is consolidated
Volume density measurement apparatus.
Background technology
For some noble metals and bijouterie ornaments, in order to verify its true and false, its density is generally first detected.Because of ornaments not
Can be destroyed, it is general at present to use Archimedes's solid density measuring method, the volume of solid ornaments is first measured with drainage, then
The weight of solid ornaments is weighed up with weighing instrument, then by calculating the density of solid ornaments.This method is not enough simply just
It is prompt, it is impossible to be integrated into a compact Special testing device.
Utility model content
The purpose of this utility model be directed to above-mentioned solid density measuring method defect one kind is provided being capable of simple and fast
Measure the double water law solid density measuring device of density of solid.
The utility model provide double water law solid density measuring device, including a built-in water container A, container A
The container B of built-in identical water is suspended with water, upper surface area and the upper surface area of container A reclaimed water of container B reclaimed water (are enclosed
Around the area of the annular water surface of container B) it is equal, range unit A is equipped with container A, range unit B is equipped with container B, survey
Connect with data processing and display module away from device A and range unit B.
To ensure that container B floats over not run-off the straight in the water of container A, the outer of relative aperture container B can be set in the upper limb of container A
The slightly larger centring ring in footpath, the top of container B is placed in the centring ring.
The optional infrared distance measurement device of range unit or resistance range unit.
Design principle of the present utility model is：
When measuring density of solid with the utility model, tested solid is submerged in the water of container B (test condition is to be put into
Container B is still in suspended state after tested solid, it is impossible to sink to the bottom), the water surface in container B is measured by the range unit in container B
Lifting height h1, the lifting height h of the water surface in container A is measured by the range unit in container A2If, in container B and container A
The upper surface area of water is s, according to Archimedes' principle, is tested the volume V=sh of solid2, it is tested the quality m=ρ of solidWaterS
h1, it is tested the density of solidI.e.Density and the h for measuring according to water1、h2, by data
Treatment and display module are the density value that can obtain solid, and are displayed on LED display.
Compared with existing Archimedes's solid density measuring method, the advantage using the utility model measurement density of solid is：
1st, it is simple to operate, it is not required to artificial calculating and can obtain density of solid value, and is shown.
2nd, device can be made compact conformation, Density Measuring Instrument with low cost, for laboratory or jewelry row etc. to noble metal
With the Fast nondestructive evaluation of bijouterie article.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the top view of Fig. 1.
In figure：1- container As, 2- water, 3- centring rings, 4- container Bs, 5- is tested solid, 6- range units B, 7- range unit
A, 8- data processing and display device, 9- supports.
Specific embodiment
The utility model is described further below in conjunction with drawings and Examples.
The double water law solid density measuring device of the present embodiment, including the larger cylindrical vessel A1 in a cross section, hold
Device A is made up of transparent organic glass, the pure water 2 of built-in certain altitude, is placed and container A material of the same race in the water of container A
Be made, the less cylindrical vessel B4 in cross section, be equipped with and identical pure water in container A in container B, container A and container B
Internal diameter size is by the upper surface area of container B reclaimed water and the upper surface area of container A reclaimed water (i.e. around the annular water surface of container B
Area) it is equal be designed, the water in container B will ensure to remain to be suspended in the water of container A after being put into tested solid 5,
Range unit A7 and range unit B6 are respectively provided with by fixed mount in the water of container A and container B, two range units pass through
Wire connects with data processing and display module 8, two optional infrared distance measurement devices of range unit or resistance range unit.
To ensure that container B is suspended in not run-off the straight in the water of container A, bore is set by support 9 in the upper limb of container A
The slightly larger centring ring 3 of the external diameter of container B, the top of container B is placed in the centring ring.
