The invention discloses a buoyancy demonstration device which comprises an air inlet pipe. The lower surface of the air inlet pipe is provided with a filter tube. The filter tube and the air inlet pipe are in communication connection. The lower surface of the filter tube is connected to a storage tube. The bottom of the storage tube is connected to a base. A water-incoming pipe is arranged between the filter tube and the storage tube. The top of the water-incoming pipe is arranged in the filter tube, and the bottom of the water-incoming pipe is connected with a pulley assembly. The pulley assembly is arranged in the storage tube. One side of the pulley assembly is connected with buoyancy balls and the other side is connected with a counterweight base. The storage tube is transversely provided with a support shaft. The support shaft passes through one side of the storage tube, and the support shaft outside the storage tube is connected to a conduit. The conduit is in a downward bending structure. The buoyancy demonstration device is convenient to use, can demonstrate buoyancy generation phenomenon and buoyancy direction clearly, and can show students buoyancy generation reasons and process directly; the teaching-assisting demonstration effect is good; the teaching difficulty of teachers is reduced; and meanwhile, the buoyancy demonstration device helps to deepen the students' further understanding of buoyancy.

To achieve these goals, the technical solution used in the present invention is such: buoyancy demonstrating device of the present invention, comprise draft tube, draft tube lower surface is provided with a strainer tube, strainer tube and draft tube are connected, strainer tube lower surface is connected on a memotron, memotron bottom is connected on a base, between strainer tube and memotron, be provided with a water inlet pipe, water inlet pipe top is positioned at strainer tube, its bottom is connected with pulley assembly, pulley assembly is positioned at memotron, pulley assembly one side is connected with buoyant spheres, its opposite side is connected with sinker, on memotron, be laterally provided with back shaft, back shaft is through memotron one side setting, and the back shaft being positioned at outside memotron is connected on a conduit, conduit is downward bending structure, it is connected with an airtight arm one end, between airtight arm and conduit, be connected by rubber plug, airtight arm is U-shaped structure, its other end and gas outlet are connected, gas outlet is horizontally installed on memotron, and gas outlet is positioned at back shaft below, on gas outlet, be vertically provided with adjuster bar, adjuster bar is positioned at memotron, adjuster bar is two, and be connected with adjustable plate between two adjuster bars, adjustable plate is provided with packoff, on adjustable plate, have cavity, packoff is positioned at cavity.
Further, as a kind of concrete version, memotron of the present invention adopts plastic material to make.
Further, as a kind of concrete version, airtight arm of the present invention adopts transparent organic glass material to make.
Further, as a kind of concrete version, on sinker of the present invention, have water inlet and water delivering orifice.
Compared with prior art, the invention has the advantages that: this buoyancy demonstrating device is easy to use, can know and show leading to a phenomenon and the direction of buoyancy of buoyancy, reason and the process that buoyancy can be produced directly show student, the good demonstration effect of aided education, reduce teacher's the difficulty of giving lessons, be conducive to deepen the further understanding of student to buoyancy simultaneously.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
In figure: 1. draft tube; 2. strainer tube; 3. water inlet pipe; 4. memotron; 5. pulley assembly; 6. buoyant spheres; 7. sinker; 8. back shaft; 9. conduit; 10. airtight arm; 11. gas outlets; 12. adjuster bars; 13. adjustable plates; 14. bases; 15. packoffs.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The preferred embodiment of buoyancy demonstrating device of the present invention as shown in Figure 1, comprise draft tube 1, draft tube 1 lower surface is provided with a strainer tube 2, strainer tube 2 is connected with draft tube 1, strainer tube 2 lower surfaces are connected on a memotron 4, memotron 4 bottoms are connected on a base 14, between strainer tube 2 and memotron 4, be provided with a water inlet pipe 3, water inlet pipe 3 tops are positioned at strainer tube 2, its bottom is connected with pulley assembly 5, pulley assembly 5 is positioned at memotron 4, pulley assembly 5 one sides are connected with buoyant spheres 6, its opposite side is connected with sinker 7, on memotron 4, be laterally provided with back shaft 8, back shaft 8 is through memotron 4 one side settings, and the back shaft 8 being positioned at outside memotron 4 is connected on a conduit 9, conduit 9 is downward bending structure, it is connected with airtight arm 10 one end, between airtight arm 10 and conduit 9, be connected by rubber plug, airtight arm 10 is U-shaped structure, its other end and gas outlet 11 are connected, gas outlet 11 is horizontally installed on memotron 4, and gas outlet 11 is positioned at back shaft 8 belows, on gas outlet 11, be vertically provided with adjuster bar 12, adjuster bar 12 is positioned at memotron 4, adjuster bar 12 is two, and be connected with adjustable plate 13 between two adjuster bars 12, adjustable plate 13 is provided with packoff 15, on adjustable plate 13, have cavity, packoff 15 is positioned at cavity, described memotron 4 adopts plastic material to make, described airtight arm 10 adopts transparent organic glass material to make, on described sinker 7, have water inlet and water delivering orifice.
