Description
Technical field
The utility model is related to a kind of experimental provision, and in particular to a kind of buoyancy experiment device for physics teaching.
Background technology
The experiment equipment for studying buoyancy in physics teaching at present is fairly simple, and operation is cumbersome, visual also bad, real
Proved recipe method is not also clearly given, lecture experiment and grouping experiment is all bad completes, and teaching efficiency is poor.Student is difficult to intuitively
Volume, weight etc. are produced with the relation of buoyancy size and is contacted.Teacher is also required to distinguish using different teaching aids when demonstrating
Into experimentation is complicated, loses time, and affects experiment effect.
Utility model content
The technical problems to be solved in the utility model is volume, weight etc. and the relation of buoyancy size to be needed to adopt at present
Different teaching aids are respectively completed, and experimentation is complicated, there is provided a kind of simple structure, can respectively demonstrate volume, weight and buoyancy
The buoyancy experiment device of relation.
To solve above-mentioned technical problem, the utility model adopts following technical proposals：A kind of buoyancy experiment device, including storage
Liquid cup, telescopic gas receiver, gas storage filling and reservoir, gas storage filling and reservoir are arranged on liquid storing cup top, and gas receiver is arranged
Inside liquid storing cup；Expansion link is provided with described gas receiver, expansion link two ends are separately fixed at the two ends of gas receiver, is stretched
Bar is provided with liquid storing barrel；The gas receiver left side is provided with air inlet, and liquid storing barrel is provided with inlet and exhaust outlet, gas receiver
Air inlet is filled with gas storage by air inlet pipe and is connected, and the inlet of liquid storing barrel is connected by feed tube with reservoir, the row of liquid storing barrel
Gas port is connected by blast pipe with air.
Described liquid storing cup is provided with fixed lid, and gas storage filling and reservoir are separately positioned on fixed lid both sides, and fixation is covered
It is provided with filling opening.
The loop bar that the expansion link includes sleeve and coordinates with sleeve, liquid storing barrel is fixed on sleeve outside.
Graduation mark is equipped with the liquid storing cup and reservoir.
Valve is equipped with the air inlet pipe and feed tube.
Described air inlet pipe, blast pipe and feed tube are flexible pipe.
Using the utility model of said structure, it is close that experimental facilities can simultaneously demonstrate volume, weight and liquid
Degree and the relation of buoyancy, make understanding of the student to buoyancy more directly perceived, increase students ' interest of study, consolidate results of learning.
Description of the drawings
Fig. 1 is the utility model structural representation.
Specific embodiment
As shown in figure 1, the utility model includes that liquid storing cup 1, telescopic gas receiver 2, gas storage fill 23 and reservoir 43, storage
Gas filling 23 and reservoir 43 are arranged on the top of liquid storing cup 1, and gas receiver 2 is arranged on inside liquid storing cup 1；Set in described gas receiver 2
There is expansion link 3, the two ends of expansion link 3 are separately fixed at the two ends of gas receiver 2, and expansion link 3 is provided with liquid storing barrel 4；The gas receiver
2 left sides are provided with air inlet 21, and liquid storing barrel 4 is provided with inlet 41 and exhaust outlet 45, and the air inlet 21 of gas receiver 2 passes through air inlet
Pipe 22 fills 23 and is connected with gas storage, and the inlet 41 of liquid storing barrel 4 is connected by feed tube 42 with reservoir 43, the exhaust of liquid storing barrel 4
Mouth 45 is connected by blast pipe 46 with air.Feed tube 42 and blast pipe 46 both pass through the outer wall of gas receiver 2, feed tube 42,
Blast pipe 46 notes good seal with the junction of gas receiver 2.During experimental demonstration, teacher is by the way that slowly water filling is seen into liquid storing barrel 4
The relation of weight and buoyancy is examined, by slowly inflation view volume and the relation with buoyancy into gas receiver 2, and by changing
The liquid of the liquid observation different densities in liquid storing cup 1 or reservoir 43 and the relation of buoyancy.
Described liquid storing cup 1 is provided with fixed lid 11, and gas storage filling 23 and reservoir 43 are separately positioned on 11 liang of fixed lid
Side, fixed lid 11 is provided with filling opening 12.Air inlet pipe 22 and feed tube 42 both pass through filling opening 12 and fill 23 and storage with gas storage respectively
