Abstract
Tester is measured to buoyancy relates to one kind and measures the experiment instruments used for education that the come -up object received great buoyancy in aqueous, including clear glass basin, the handheld support frame of taking the pulley, cotton rope, foamed plastic piece, dynamometer etc.. Characterized by: little pulley mounting is on handheld support frame, constitute a handheld support frame of taking the pulley, the combination of handheld support frame and truckle, with little pulley mounting at handheld support frame lower extreme, constitute a support frame of taking the pulley, the upper end is the handle, the foamed plastic piece is tied to the one end of cotton rope, the other end is even on the dynamometer, during the experiment, float the foamed plastic piece at the surface of water, the cotton rope of flare -outing, handheld handle, with the recess alignment line of the truckle rope bottom of impressing, let the lower extreme of support frame touch the cylinder bottom, make the truckle keep perpendicular with the horizontal plane, push down the support frame hard, the dynamometer up draws, draw in the aquatic with the foamed plastic piece, the dynamometer shows great power, then that the foamed plastic piece receives great buoyancy in aqueous.
Description
Technical field
Compulsory education curricular standard experimental teaching material " religion section version " " science " five grades volume two " heavy and floating " unit, the grouping experiment of " buoyancy " class: measure the object of object and the sinking floated in water by buoyancy of water." ergometer used; ergometer can only upwards carry; surveying the object floated very inconvenient by great buoyancy in water, this buoyancy experiments of measuring device device can easily measure the buoyancy that the object of floating is subject in water, belongs to the experimental apparatus in school science experimental teaching.
Background technology
Measure the buoyancy that foam-plastic blocks is subject in water, teaching material is such arranged: clear glass tank is filled water, a truckle fixed by bottom plasticine, foam-plastic blocks is tied with one end of fine rule, the other end is enclosed within ergometer through truckle and pulls up, foam-plastic blocks is drawn in water, the great power of ergometer, then it represents that foam-plastic blocks receives great buoyancy in water.
This experimental design obtains the most ingenious, but have ignored a problem: be not fix truckle in water with plasticine, the easy softening of water time length met by plasticine, can not root bottom glass flume again, ergometer pulls up rope gently, truckle just comes off from bottom of gullet, causes the unsuccessful of experiment.This buoyancy experiments of measuring device device, the object of the very convenient floating completing " heavy and floating " unit of energy is in the experiments of measuring of buoyancy size.
Summary of the invention
This utility model buoyancy experiments of measuring device relates to a kind of measuring floating object experiment teaching instrument by great buoyancy in water, including clear glass tank, the hand-held supports frame of band pulley, cotton rope, foam-plastic blocks, ergometer, it is characterized in that: truckle is arranged on hand-held supports frame, the hand-held supports frame of one band pulley of composition, cotton rope is enclosed within truckle the press-in bottom, above carries ergometer and is drawn in by foam-plastic blocks and measure it in water in water by great buoyancy.Bracing frame upper end is handle, and foam-plastic blocks is tied in one end of cotton rope, and the other end is connected on ergometer, during experiment, foam-plastic blocks is kept afloat, stretch cotton rope, hand-held handle, is directed at the groove of truckle the cotton rope press-in bottom, allows the lower end of bracing frame contact cylinder bottom, truckle is made to keep and horizontal plane, firmly pushing down bracing frame, foam-plastic blocks, toward pull-up, is drawn in water by ergometer, ergometer shows great power, then be foam-plastic blocks in water by great buoyancy.Beneficial effect: easy to assembly, hand-held supports frame controls truckle, and two handss need not put in and just can complete experiment, experiment success rate 100% in water.
Accompanying drawing explanation
Accompanying drawing 1 is buoyancy experiments of measuring device schematic diagram of device, and accompanying drawing 2 is the hand-held supports frame side view of band pulley, its sequence number successively: 1. clear glass tank, 2. hand-held supports frame, 3. truckle, 4. handle, 5. cotton rope, 6. foam plastics, 7. ergometer, the 8. water surface.
Detailed description of the invention
Buoyancy experiments of measuring device device, including clear glass tank, hand-held supports frame, truckle, cotton rope, foam-plastic blocks, ergometer etc..It is characterized in that: hand-held supports frame (2) is combined with truckle (3), truckle is arranged on hand-held supports frame lower end, the hand-held supports frame of one band pulley of composition, bracing frame upper end is handle (4), foam-plastic blocks (6) is tied in one end of cotton rope (5), the other end is connected on ergometer (7) hook, during experiment, foam-plastic blocks and cotton rope are floated on the surface, stretch cotton rope, bracing frame mentioned by hand-held handle, the groove of truckle is directed at the bottom of cotton rope press-in glass jar, the lower end allowing bracing frame contacts cylinder bottom, truckle is made to keep and horizontal plane, firmly push down bracing frame, ergometer is toward pull-up, the foam-plastic blocks being enclosed within cotton rope is drawn in water, ergometer shows great power, be then foam-plastic blocks in water by great buoyancy.
