The utility model has related to the instruments used for education field, is particularly for a kind of liquid injection air exhaust type sinking and floating condition demonstrator.Be applicable to physics teaching in secondary school test use, also can be used for the place that other needs to verify, demonstrate Archimedes' principle.Buoyancy is an important physical concept, in teaching, how to make the beginner get Archimedes' principle clear, get the weight of object that is immersed in the liquid and the relation of liquid buoyancy clear, it is not enough depending merely on oral lecturing with textbook, often needs logical demonstration, next directly perceived, vivid this physical concept of grasp of test.Therefore, the Demonstrator Trials of buoyancy condition just seems particularly important.The demonstration teaching aid of buoyancy in the existing physics teaching mostly is the experiment teacher and starts voluntarily to be provided with to build to finish temporarily, limits based on condition, makes that the not enough science of demonstration is tight, and experiment effect is not ideal enough.A kind of " demonstration of object sinking and floating condition " of being produced by certain Educational Instrument Factory arranged, be applied in some schools in recent years.This instrument is made up of transparent bucket, buoyancy aid and a screw-plunger compression system, and buoyancy aid is that the flask of portion's opening under water is equipped with in an inside, is immersed in the beverage container.By regulating compression system, the pressure that changes in the beverage container changes what (liquid level height) of liquid in the buoyancy aid, thereby has changed buoyancy aid weight, makes it equal to be greater than or less than buoyancy, demonstrates out balance and the sink-float situation of object in water.Owing to be located at the heaviness, blunt, insensitive of the screw rod compression system of beverage container top, make the variation and the pressure in the beverage container of the interior water yield of buoyancy aid change and to carry out synchronously, when doing the sinking and floating condition demonstration, buoyancy aid is unstable up and down in water, difficult realization buoyancy aid is regular sinking and come-up with the variation of pressure, error is bigger, has influenced the demonstration effect.
It is simple that the purpose of this utility model is to disclose a kind of novel structure, and manual dexterity is convenient, and demonstrating visual is the sinking and floating condition demonstrator clearly---liquid injection air exhaust type sinking and floating condition demonstrator, with better demonstration and verification Archimedes' principle, improve the quality of teaching.
Design of the present utility model be manage with existing demonstrator change directly water filling in buoyancy aid into to the buoyancy aid internal drainage indirectly, simplified structure is beneficial to operation, reduces error.
Specifically, the utility model is made up of beverage container, buoyancy aid bottle, liquid injection pipe, gas outlet and syringe five parts.Beverage container is the top uncovered hydrostatic column that a usefulness transparent material (glass or plastics etc.) is made, and the inside fills liquid (being generally water), and beverage container is marked with the scale that shows liquid level (water yield how much).The buoyancy aid bottle is one can insert the transparent apertures container in the beverage container, makes with transparent materials such as glass or plastics, and opening part seals with the Elastic plastic-rubber bottle cap.In the bottle certain quantity of fluid (being generally water) is housed.The buoyancy aid bottle is that mouth down is inverted submergence and is suspended in the knapsack, in the outer cover of buoyancy aid bottle the balancing frame of one garden shape is housed, in order to keep stable, the balance of buoyancy aid bottle in beverage container.Have pilot hole on the balancing frame.Liquid injection pipe is a small hose, and one end (liquid feeding end) is connected on the syringe that is positioned at the beverage container outside, and the other end (outlet end) passes bottle cap and inserts in the buoyancy aid bottle, is used for to fluid injection of buoyancy aid bottle or drawing liquid; Gas outlet also is a small hose, and the one end passes bottle cap and inserts the top (air position) of arriving bottle in the buoyancy aid bottle, and the other end reaches the knapsack outside, is used to discharge the air in the buoyancy aid bottle, is convenient to fluid injection.During use, be marked with a certain amount of water in the buoyancy aid bottle, make its inversion be immersed in the knapsack inner suspension and keep stable on a certain position, water then rises to a certain height and position in the beverage container.At this moment, the weight of object (buoyancy aid bottle) equate with buoyancy of liquid, balance.During the demonstration sinking and floating condition, pass through liquid injection pipe water filling in buoyancy aid lentamente with syringe, the weight of buoyancy aid bottle is slowly increased, can clearly observe rising gradually, be immersed in buoyancy aid bottle in the water and sink gradually (this moment object great) in buoyancy of water along with liquid level in the buoyancy aid.Otherwise when extracardiac pumping, the weight of buoyancy aid bottle slowly reduces, and can see the reduction gradually along with liquid level in the bottle with syringe, and the buoyancy aid bottle is slowly rising (at this moment, the weight of object is less than buoyancy of water) in water.So very clearly demonstrated the sinking and floating condition in the Archimedes' principle intuitively.
The utility model is owing to be provided with liquid injection pipe and gas outlet directly is connected with the buoyancy aid bottle, with adopted directly water filling or draw water in buoyancy aid of syringe, make that the sinking and floating condition demonstrator novel structure that becomes is simple, flexible and convenient operation, and have accurate, clear, the advantage intuitively of demonstration effect.Very strong practical value is arranged.
