Abstract
The utility model discloses an experiment demonstration device of controlling object drift phenomenon, comprising an outer shell and an inner shell, wherein the outer shell is filled with water while the inner shell, being filled with certain amount of water, is inversely placed inside the outer shell. By changing the shape and the squeezing manner of the outer shell, the demonstration effect of the Descartes Cartesian diver experiment can be diversified, thereby making the experiment more vivid and interesting and further arousing students for innovation.
Description
Technical field
The utility model belongs to the teaching demonstration device technical field, relates to a kind of drift along experimental demonstration device of phenomenon of object of controlling.
Background technology
Middle school physics drifts along for the research object in the dive in water of condition, submarine and the come-up teaching, and the teacher requires the student to make Descartes's Cartesian diver by oneself in order to cultivate students'experiment ability and scientific spirit.Existing apparatus for demonstrating is to place an object in the water-filled container, and object is above water when initial, and hand bottle object sinks, the back object come-up of loosing one's grip.But such demonstration effect is comparatively single, and experiment is lively inadequately, entertaining.
Summary of the invention
The purpose of this utility model provides a kind of drift along experimental demonstration device of phenomenon of object of controlling, and can make the variation of Descartes's Cartesian diver experimental demonstration effect, makes experiment more lively, interesting.
The technical scheme that the utility model adopted is, a kind of drift along experimental demonstration device of phenomenon of object of controlling comprises external bottle and places inner bottle in the external bottle, and be full of water in the external bottle, inner bottle is inverted in the external bottle, and a certain amount of water is housed in the inner bottle.
Characteristics of the present utility model also are,
Wherein the xsect of external bottle is positive circular.
Wherein the xsect of external bottle is oval.
Wherein the xsect at external bottle two ends is positive circular, and the xsect at external bottle middle part is oval.
The beneficial effects of the utility model are, by the change of external bottle shape, and to the change of external bottle fashion of extrusion, produce different sink-float phenomenons, thereby make this test vivid and interesting more, more can motivate students' interest in learning and innovation ability.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model is a kind of controls the drift along experimental demonstration device of phenomenon of object, as shown in Figure 1, comprises external bottle 1 and inner bottle 2, is full of water in the external bottle 1, and inner bottle 2 is inverted in the external bottle 1, and a certain amount of water is housed in the inner bottle 2.
First kind of embodiment of the utility model, as shown in Figure 2, the xsect of external bottle 1 is positive circular.
First kind of embodiment is when the experiment of demonstration sinking-floating object, inner bottle 2 not exclusively is full of water, inner bottle 2 is put into water-filled external bottle 1, adjust the water yield in the inner bottle 2, make it to float over external bottle 1 top, behind the demonstration teacher slightly compressed external bottle 1, according to Pascal law, when air is compressed, the pressure transmission is fed water, water is pressed in the inner bottle 2, with the compression of the air in the inner bottle 2, at this moment enter some water in the Cartesian diver, the gravity of inner bottle 2 increases, the buoyancy that is subjected to greater than it is just to sinking.As demonstration teacher when no longer pushing external bottle 1, pressure reduces in the external bottle 1, and the compressed air in inner bottle 2 the insides comes out hydraulic pressure, this moment inner bottle 2 gravity less than its suffered buoyancy, so it is just to come-up.When hand was suitable to external bottle 1 applied pressure, inner bottle 2 just was suspended on any degree of depth in the water.
Second kind of embodiment of the utility model, as shown in Figure 3, the xsect of described external bottle 1 is oval.
Second kind of embodiment of the utility model, as shown in Figure 4, the xsect at external bottle 1 two ends is positive circular, the xsect at external bottle 1 middle part is oval.
Second kind with the third embodiment in demonstration sinking-floating object when experiment, inner bottle 2 not exclusively is full of water, and inner bottle 2 is put into water-filled external bottle 1, adjusts the water yield in the inner bottle 2, makes it to float over external bottle 1 top.
The teacher is after the short-axis direction slightly compressed of external bottle 1 oval cross section in demonstration, and external bottle 1 cross-sectional area reduces, and water is pressed in the inner bottle 2, with the compression of the air in the inner bottle 2, at this moment enter some water in the Cartesian diver, the gravity of inner bottle 2 increases, the buoyancy that is subjected to greater than it is just to sinking.As demonstration teacher when no longer pushing external bottle 1, external bottle 1 recovers original area of section, and pressure reduces in the external bottle 1, and the compressed air in inner bottle 2 the insides comes out hydraulic pressure, this moment inner bottle 2 gravity less than its suffered buoyancy, so it is just to come-up.
Also can regulate the water yield of inner bottle 2, make inner bottle 2 just be sunken to external bottle 1 bottom, as shown in Figure 5, the teacher is after the long axis direction slightly compressed of external bottle 1 oval cross section in demonstration, external bottle 1 cross-sectional area increases, because water is by by detaching in the inner bottle 2, the gravity of inner bottle 2 reduces, the gravity of inner bottle 2 is less than its suffered buoyancy at this moment, and inner bottle 2 will be begun to rise by top.Otherwise when the demonstration teacher no longer pushed external bottle 1, inner bottle 2 will sink down into external bottle 1 bottom.
The difference of the utility model sinking-floating object experimental demonstration device and Cartesian Cartesian diver is, inner bottle 2 was above water when Cartesian Cartesian diver was initial, and the utility model device inner bottle 2 both can be above water when initial, again can be below water, innovative point has solved by the extruding bottle and object sunk or come-up, better cultivates innovation ability of students in the current techique teaching.
Device of the present utility model has compressibility, water to the transmission of pressure and object the probing into of condition of drifting along in order to demonstration buoyancy of water, gas.
