Description
Technical field
The utility model relates to the teaching aid in the physics teaching in secondary school, is specially a kind of liquid internal pressure experimental provision.
Background technology
At present, the used teaching aid in middle school has a lot, general all design and produce at needed experiment separately, and function singleness, and the operation of some teaching aid is also very inconvenient.Liquid internal pressure is a difficult point in the middle of the physics of middle school, and its related experiment has, the pressure of the same degree of depth different directions of liquid internal; The pressure of liquid internal different depth; The pressure of liquid internal is with the relation of fluid density.Involved experimental demonstration equipment has, " 2113 liquid internal pressure tester ", " 2114 small piezometer " or " 2185 liquid pressures and depth relationship tester ", the mechanical rotation break-in probe cassette in " 2113 liquid internal pressure meter " often take place to turn to malfunctioning problem because of belt slip when experiment; " 2114 small piezometer " or " 2185 liquid pressures and depth relationship tester " not only installs complicated, and difficult operation, and price height are not durable.
Summary of the invention
It is a kind of simple in structure, easy to make that the purpose of this utility model is to provide, and cost is low, and is easy to operate, multiduty liquid internal pressure experimental provision.
A kind of liquid internal pressure experimental provision of the utility model, comprise base 1, survey box 3, long handle supporting plate 4, be fixed on the transparent tube 2 simple and easy piezometers 6 on the base 1, and connect the communicating pipe 5 of surveying box 3 and simple and easy piezometer 6 and place the magnet of surveying in the box 7, it is characterized in that transparent tube 2 outer walls are provided with highly and indicate; Survey box 3 and be the box-like of an end opening, main body is a nonmagnetic substance, and openend is sealed by rubber membrane, is connected with communicating pipe 5 in a side seal, and inside bottom is fixed with and the identical magnet 7 of bottom size; Long handle supporting plate 4 is made by magnetic material, and integral body is the L type, and length is greater than the height of transparent tube 2; Simple and easy piezometer 6 is made up of plank and U-shaped pipe, and the U-shaped pipe is fixed on the plank, and an end connects pipe 5.
A kind of liquid internal pressure experimental provision of the utility model, it mainly is to utilize the magnetic of magnet 7 and long handle supporting plate 4 forms different positions and concerns, measures the liquid internal pressure of diverse location respectively, indicates to determine liquid depth by the height of transparent tube 2 outsides, the size that shows pressure by simple and easy piezometer 6, its beneficial effect is, and is reasonable in design, simple in structure, easy to make, cost is low, and is easy to operate, multi-usage.

Among the figure: base 1, transparent tube 2, detection box 3, long handle supporting plate 4, communicating pipe 5, simple and easy piezometer 6, magnet 7, liquid 8
Embodiment
Example 1
A kind of liquid internal pressure experimental provision of the utility model comprises base 1, surveys box 3, and long handle supporting plate 4 is fixed on the transparent tube 2 simple and easy piezometers 6 on the base 1, and connects the communicating pipe 5 of surveying box 3 and simple and easy piezometer 6 and place the magnet of surveying in the box 7.Do the pressure intensity testing of the same degree of depth different directions of demonstration liquid internal.When beginning to test, check impermeability earlier, insert in the water of graduated cylinder surveying box 3 that water column can form a water-head in the U-shaped pipe of simple and easy piezometer 6, highly constant as surveying box 3, water-head is also constant, proves that device is air tight, begins experiment then.The first an amount of water of in transparent tube 2, packing into, be attached to above the long handle supporting plate 4 surveying box 3 any suctions then, long handle supporting plate 4 is inserted in the water of transparent tube, make rubber membrane and predefined transparent tube 2 outer walls one fixedly scale be in same surface level, form a water-head in the U-shaped pipe of simple and easy piezometer 6, note the same degree of depth but rubber die up, down, the detection box 3 formed water-heads when erectting rotation compare, draw experiment conclusion: the pressure of the same degree of depth different directions of liquid internal is identical.
Example 2
A kind of liquid internal pressure experimental provision of the utility model, it forms identical with example 1 with the preceding preparation of experiment, do the pressure intensity testing of demonstration liquid internal different depth, other step is all identical with example 1, just do not change the paste position of surveying box 3, only change the degree of depth in the water of at every turn pasting the long handle supporting plate 4 insertion transparent tubes of surveying box 3, the water-head that writes down respectively in the simple and easy piezometer 6 compares, draw experiment conclusion: the pressure difference of liquid internal different depth, the dark more then pressure of liquid is big more.
Example 3
A kind of liquid internal pressure experimental provision of the utility model, it forms identical with example 1 with the preceding preparation of experiment, do of the experiment of the pressure of demonstration liquid internal with the relation of fluid density, earlier the long handle supporting plate 4 of surveying box 3 is being pasted in suction and stretching into the degree of depth place that sets in the interior liquid 8 of transparent tube 2, observing and writing down the water-head of U-shaped pipe in the simple and easy piezometer 6.Then the liquid in the transparent tube 28 is changed into different liquids, still repeat aforesaid operations, the record water-head compares, and draws experiment conclusion: the pressure of liquid internal is relevant with density of liquid, and density of liquid is big more, and its inner pressure is big more.
