Description
Technical field
This utility model is related to teaching aid technical field, especially relates to a kind of buoyancy teaching demonstration apparatus.
Background technology
Buoyancy phenomenon in the middle of life is not strange for student, but the curricula with regard to buoyancy always is
Emphasis in physics teaching and difficult point, generally under the guiding of teacher, drive student to recognize buoyancy presence in laboratory observation
Phenomenon and the principles of science.However, due to the limitation of Self-made Realia, universal demonstration teaching aid generally do not have good directly perceived,
Lively displaying function, buoyancy demonstration tests inadequate concrete image, is unfavorable for that student carries out Experimental Research by meticulous inspection, adjusts
Do not move the enthusiasm of student's participation, and the study desire of the thinking that beats one's brains, knowledge.
Utility model content
This utility model is directed to the deficiencies in the prior art, and technical problem to be solved is to provide a kind of buoyancy teaching demonstration
Apparatus, the demonstrating floating force phenomenon that it can be directly perceived, lively as teaching aid, mobilizing students take action on one's own, play an active part in long-pending
Polarity, carries out Experimental Research by meticulous inspection, strengthens desire for knowledge.
This utility model is so that above-mentioned technical problem is addressed by the following technical programs.
A kind of buoyancy teaching demonstration apparatus, including tank, lifting buoy, Bubbled stone, appendix and solar energy air pump box, water
Setting lifting buoy and Bubbled stone in groove, Bubbled stone is connected with solar energy air pump box by appendix, and lifting buoy includes plastics
Support, counter weight base, balancing weight and nylon wire, the upper end of plastic stent is coated with umbrella nylon wire, and the mesh of nylon wire is 10
To 16, the lower end setting counter weight base of plastic stent, it is provided with balancing weight in counter weight base.
Preferably, the upper end of plastic stent is provided with umbrella frame, nylon wire is coated on described umbrella frame.
Preferably, counter weight base is semiclosed shape cylinder.
Preferably, the opening of counter weight base is threaded in the lower end of plastic stent.
Preferably, balancing weight is circular metal plate, two to three balancing weights overlay in the inner chamber of counter weight base.
Preferably, counter weight base is plastic material structure.
Preferably, the surface of solar energy air pump box is provided with solar panel, it is provided with and the sun in solar energy air pump box
The lithium battery that energy cell panel matches.
The beneficial effects of the utility model：
1. the aerofluxuss of solar energy air pump box produce bubble by Bubbled stone, and bubble is ceaselessly attached on nylon wire and passes through buoyancy
Drive lifting buoy to float upwards, when emerging, constantly rupture loss of buoyance with bubble, rely on the gravity of balancing weight to make
With making lifting buoy submerged, thus move in circles and achieve the buoyancy phenomenon lecture experiment floating and settling, intuitively may be used
Depending on, vivid, be easy to students meticulous inspection, probe into buoyancy phenomenon.
2. the experimentation of solar power supply and Bubbled stone generation bubble, improves the enjoyment of experience buoyancy experiment,
The enthusiasm that mobilizing students are taken action on one's own, played an active part in, guiding students beat one's brains thinking, strengthen and pursue the study of scientific knowledge and be intended to
Hope.
3. component is few, makes simple, demonstration easily, is conducive to popularization and application.
