Abstract
The utility model discloses experimental apparatus is measured to buoyancy relates to experiment instruments used for education of measuring the buoyancy that receives in aqueous of come -up object, including clear glass basin, sucking disc, truckle, go -between, cotton rope, foamed plastic piece, dynamometer etc. Characterized by: the combination of sucking disc and truckle: fixing the truckle on the sucking disc with the go -between, constituteing a sucking disc of taking the pulley, the sucking disc adsorbs at the bottom of gullet, and the cotton rope is sheathe in to the truckle, and the foamed plastic piece is tied to one end, and even on the dynamometer, the dynamometer up draws the other end, draws in the aquatic with the foamed plastic piece, and the dynamometer shows great power, then is that the foamed plastic piece receives great buoyancy in aqueous. Beneficial effect: convenient assembling, sucking disc no. 1 inhale and surely, test success rate 100 percent.
Description
Technical field
Compulsory education curricular standard experimental teaching material " religion section version " " science " five grades volume two " heavy with floating " unit, " buoyancy " grouping experiment of class: the object measuring object and the sinking of floating in water is subject to buoyancy of water." dynamometer used; dynamometer can only upwards be carried; surveying the object floated, in water, be subject to great buoyancy very inconvenient, and the buoyancy that the object that this buoyancy experiments of measuring device can easily measure 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, arrange like this in teaching material: clear glass tank is filled water, a small sheave fixed by bottom plasticine, foam-plastic blocks is tied with one end of fine rule, the other end is enclosed within dynamometer to pull-up through small sheave, foam-plastic blocks is drawn in water, the great power of dynamometer, then represent that foam-plastic blocks receives great buoyancy in water.
This experimental design obtains very ingenious, but have ignored a problem: be do not fix small sheave with plasticine, and plasticine is of a specified duration in water easily to be softened, can not take root bottom glass flume, dynamometer upwards one draws gently, and small sheave has just come off from bottom of gullet, causes the unsuccessful of experiment.This buoyancy experiments of measuring device, very conveniently can complete the buoyancy experiments of measuring of whole " heavy and floating " unit.
Summary of the invention
The utility model buoyancy experiments of measuring device relates to a kind of experiment teaching instrument measuring the buoyancy that floating object is subject in water, comprises clear glass tank, sucker, small sheave, abutment ring, cotton rope, foam-plastic blocks, dynamometer etc.It is characterized in that: the combination of sucker and small sheave: with abutment ring, small sheave is fixed on sucker, form the sucker of a band pulley, sucker suction is at bottom of gullet, small sheave puts cotton rope, and foam-plastic blocks is tied in one end, and the other end is connected on dynamometer, dynamometer is toward pull-up, drawn in by foam-plastic blocks in water, dynamometer shows great power, be then that foam-plastic blocks is subject to great buoyancy in water.Beneficial effect: easy to assembly, sucker one is inhaled also steady, experiment success rate 100%.
Accompanying drawing explanation
Accompanying drawing 1 is buoyancy experiments of measuring schematic diagram of device, its sequence number successively: 1. clear glass tank, 2. sucker, 3. small sheave, 4. abutment ring, 5. cotton rope, 6. polyfoam, 7. dynamometer, the 8. water surface.
Embodiment
Buoyancy experiments of measuring device, comprises the small sheave, cotton rope, foam-plastic blocks, dynamometer etc. of clear glass tank, band sucker.It is characterized in that: with abutment ring (4), small sheave (3) is fixed on sucker (2), form the sucker of a band pulley, sucker suction is in tank (1) bottom, and small sheave puts cotton rope (5), foam-plastic blocks (6) is tied in one end, and the other end is connected on dynamometer (7).During experiment, tank topped up with water, dynamometer is up carried, and foam-plastic blocks is drawn in water by the other end of cotton rope, dynamometer shows great power, be then that foam-plastic blocks is subject to great buoyancy in water.
Claims (1)
1. buoyancy experiments of measuring device comprises small sheave, abutment ring, cotton rope, foam-plastic blocks, the dynamometer of clear glass tank, band sucker, it is characterized in that: the combination of sucker and small sheave---small sheave is fixed on sucker, form the sucker of a band pulley, sucker suction is at bottom of gullet, small sheave puts cotton rope, and foam-plastic blocks is tied in one end, and the other end is connected on dynamometer, foam-plastic blocks, toward pull-up, is drawn in water and is measured it in water, be subject to much buoyancy by dynamometer.
