Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Figure 1-Figure 2, a kind of aerostatic buoyancy suspension device of physics experiment teaching, comprise fixed pulley 3, irony counterweight 5, inflation lift pump 7 and O-ring seal 10, base upper end is provided with bottom end cover 13, bottom end cover 13 upper end is provided with sponge 6, sponge 6 can play buffer action to the whereabouts of irony counterweight 5 or demonstration ball 11, prevent the destruction of demonstrating cylinder 12, demonstration cylinder 12 inside is provided with fixed pulley 3, fixed pulley 3 side is provided with irony counterweight 5, fixed pulley 3 opposite side is symmetrically arranged with demonstration ball 11, object and the result of experiment can be seen clearly by demonstration ball 11, O-ring seal 10 upper end is provided with fastening bolt 9, O-ring seal 10 inside is provided with sealing-plug 8, for sealing, sealing-plug 8 inside is provided with conduit 4, carry out inflating and air-breathing in demonstration cylinder 12 by conduit 4, conduit 4 side is provided with inflation lift pump 7, inflation lift pump 7 side is provided with air-filled pore 14, inflation lift pump 7 opposite side is provided with suction hole 15.
In said structure, demonstration cylinder 12 is made with transparent organic glass pipe, air inlet/outlet is established in lower end, by sealing-plug 8 and end cap seal. repack a sensitive fixed pulley 2 into verge ring, demonstration ball 11 is fixed at one end glue of line 3, be suspended on fixed pulley 2, and hang irony counterweight 5 at the other end of line 3, make Balance weight end equal with bead end moment, be in equilibrium state, fixed pulley 5 and hanger are together sealed. with inflate lift pump 7 inflate time, air pressure in demonstration cylinder 12 increases, increase in density, the buoyancy that bead is subject to increases, when being enough to the buoyancy difference with counterweight the resistance overcoming bead gravity and balanced system greatly, bead starts to float.During air-breathing, the air pressure in demonstration cylinder 12 reduces, and density diminishes, and buoyancy reduces, and demonstration ball 11 starts to sink. and when bead is in atmospheric pressure state, affect irony counterweight 5 with magnet, bead can be parked in any height, can be considered as suspending.
