Description

A kind of ice concentration measurement apparatus
Technical field
The present invention relates to a kind of measurement of the ice concentration of density measuring equipment technical field, especially density measure for ice Device.
Background technology
With the exploitation of China Higher level ice formation ice breaker technology, Ship Design engineer proposes to water pool model experiment Higher technical requirements.Experimental tank will not only carry out routine without the model test under frozen water domain, and also wanting can be in laboratory Sea ice environment is simulated, realizes the forecast and assessment to ship icebreaking characteristics.During to ensure ship model experiment, can ice is turned over hull Turn, compressional movement it is similar to true sailing condition, it is desirable to can ice can be consistent with sea ice in density.Ice concentration is that experiment is surveyed One important indicator of amount.
Conventional way is the quality and volume by measuring ice cube, and then is calculated using formula and obtain ice concentration.Although The principle of this measuring method is very simple, but when actually measuring often due to the thawing of ice cube, broken and volume are not advised The generation of substantial measurement errors is then caused, so as to cause measurement error.Therefore, the measurement of ice concentration at present is mainly used and weighed Method.
For the density by testing accurate measurement ice, divide ice concentration measurement to 3 steps.Key step is described as follows institute Show：
(1) container for filling the certain mass aqueous solution is positioned on electronic scale, presses " peeling " key, by the weight of electronic scale Zero setting, i.e. m1=0；
(2) ice cube is cut out from obtained ice by the use of instrument as ice cube to be measured, ice cube to be measured is put into and filled necessarily The container of mass aqueous solution, measurement obtain quality m2；
(3) ice cube to be measured is immersed in the water of container with instrument, synchro measure obtains quality m3。
Wherein, m2=ρi·Vi；m3=ρw·g·Vi/g。
Therefore,
In above formula, ρwIt is the density of the aqueous solution, ρiIt is the density of ice, ViIt is the volume of ice.
The quality of measurement above-mentioned two step is only needed using such method, recorded electronic scale indicating value number, passes through calculating Obtain ice concentration.But there is also three problems：
(1) easily cause the ice cube that cuts irregular.Because the ice sample block cut is except that will measure its density, it is also necessary to enter The follow-up coefficient of kinetic friction experiment of row, not big enough with model contact surface if ice cube is irregular, then coefficient of kinetic friction experiment can not Carry out.
(2) test error is easily produced.When ice cube is immersed in the water by manual operation, displacement of volume can be also immersed in water because of instrument In and be more than ice cube volume, the mass value now obtained has certain error, so as to influence the ice concentration being subsequently calculated Value.
(3) operation inconvenience.Because the process of experiment is all manual operation, when ice cube is immersed in the water, it is necessary to synchronization The quality of measurement now, this can make troubles to operation.
The content of the invention
The shortcomings that the applicant is directed in above-mentioned existing production technology, there is provided a kind of ice concentration measurement apparatus, so as to reality Now the rule of collection ice sample is cut, simple operation, and can be very when using weight method to measure the quality of two steps Reduce test error well, so as to obtain accurate ice concentration value.The present invention experiment with measuring technology development field, have one Fixed engineering practicability and application value.
The technical solution adopted in the present invention is as follows：
A kind of ice concentration measurement apparatus, including cut two parts of ice production apparatus and pressure ice production apparatus, the structure for cutting ice production apparatus For：Including pressing plate, circular hole is provided with the middle part of the pressing plate, pressing plate centre position bottom is provided with band and cuts the square of skate blade Groove, the periphery root of square groove is provided with outer ring, the outer ring is locked by fixing screws and pressing plate, the square groove Outside is additionally provided with reinforcement；
It is described pressure ice production apparatus structure be：Including base, one end of the base is provided with perpendicular by round nut Guide pillar, the upper end of the guide pillar is provided with rack, the gear engaged, in addition to movable stand, the top of the movable stand Gear is installed, the right-hand member of the movable stand is connected by right side handwheel with guide pillar, and the left end of the movable stand passes through left side handwheel Installation pressure ice tentacle.
Its further technical scheme is：
The pressing plate rectangularity structure.
The upper end of guide pillar processes one section of plane, and rack is installed on that plane.
The mounting structure of gear is：Gear is connected by key with rotary shaft, and the rotary shaft passes through bearing, boring cover, transparent cover It is connected with lock-screw with movable stand；Handle is directly connected on the rotating shaft.
The integrated structure of ice tentacle is pressed, it includes the connecting pole at top, and the bottom of the connecting pole is extended with connecting shaft, The bottom of connecting shaft is extended with triangle tentacle, and the bottom of the triangle tentacle is provided with hole, installation is interference fitted in the hole There is thin bar, the thin bar bottom is plane, and is abutted with ice cube surface.
Beneficial effects of the present invention are as follows：
The present invention it is compact-sized, reasonable, it is easy to operate, by using cut ice production apparatus with press ice production apparatus cooperating, Measurement work can be conveniently accomplished on pressure ice production apparatus, so as to which convenient calculate obtains density value.Operation is simplified, improves work Reliability.
Ice production apparatus of the present invention of cutting can conveniently and efficiently cut out the ice sample block of rule, laborsaving and efficient, simultaneously The ice cube of rule provides guarantee for experiments such as the follow-up coefficients of kinetic friction.
During use of the present invention, when being just pressed into ice cube in water by pressing ice tentacle, right side handwheel is screwed, now Ice cube arranges the volume of water i.e. equal to the volume of ice cube, so as to avoid the draining caused by ice cube is immersed in the water using instrument Test error caused by volume increase.
During use of the present invention, after ice cube reaches suitable height, right side handwheel is first screwed, then measures its quality, Need not the quality of synchro measure now when manually ice cube is immersed in the water, it is more convenient in operation.
