Abstract
The utility model discloses a liquid pressure and depth relation experimental device, which comprises a liquid loading cylinder, a floating body which is arranged on the liquid loading cylinder, a counterweight and an adjutant read ring, wherein, the floating body is a whole sealed type flat bottom column-shaped body, the inner part of which is fixed with the counterweight with larger density material. A dummy club hole of the top end of the floating body is also matched and hung with a microdynamometer. The utility model has the characteristics of reasonable design, convenient experimental operation, time saving and accuracy, and can read the physical quantity of being measured. The liquid pressure and depth relation experimental device is an ideal physics educational apparatus.
Description
The utility model relates to a kind of physics educational apparatus, relates to a kind of liquid pressure and depth relationship tester specifically.
The relation experiment of the liquid pressure and the degree of depth is the student experiment in group that must do in the physics teaching in secondary school.In the domestic current instrument, number for CN2147609Y discloses a kind of liquid pressure and buoyancy aid condition experiment device, it has adopted the open type loading tube of knapsack and configuration and has put into loading within it as the novel patent announcement of practicality.But in whole experiment, all require the loading tube vertically to swim in the liquid, when the increase and decrease loading,, easily produce inclination even topple over phenomenon even if careful operation all is difficult to realize the symmetry of each quality unit to loading tube central axis.Open type loading tube is easy to cause the back water inlet of tilting in addition, has changed the weight of loading tube and loading, the obvious difference of experimental result before and after can causing toppling over, even failure.Another weak point is the relation that the increase and decrease loading can only be studied loading pressure and degree of depth under several certain depth conditions discontinuously, can not realize the research of loading tube pressure and depth relationship under depth conditions arbitrarily, to the student with misleading.
The purpose of this utility model is for solving the problem that above-mentioned technology exists, and a kind of reasonable in design, experimental result physical experiment apparatus of liquid pressure and depth relationship accurately is provided.
For achieving the above object, technical solution of the present utility model is finished like this: liquid pressure and depth relationship tester, comprise buoyancy aid, the counterweight of knapsack and configuration thereof and help read the ring, described buoyancy aid is the flat cylindrical body of a totally-enclosed shape, bottom within it is fixed with mass, hangs with microdynamometer by also joining in the boss hole of buoyancy aid top.
The technical solution of the utility model also comprises: described microdynamometer is by the scale that has row's demonstration weight on the dynamometer body at least, the hook that installs a spring in the middle and have; The maximum displaced weight of described sealing buoyancy aid is 1: 1 with the ratio of himself weight.
The utility model has following characteristics compared to existing technology.
1, this instrument adopts dynamometer to hang proportion to be about 1 centre of gravity buoyancy aid and to experimentize, guaranteed the stability of buoyancy aid in liquid in the experimentation.
2, change the degree of depth of buoyancy aid in liquid, only need to change the height of microdynamometer.Experimental implementation is simple, has realized the arbitrariness and the continuity of the buoyancy aid degree of depth in research liquid pressure and the depth relationship again.
3, buoyancy aid is totally-enclosed shape structure, needn't worry that buoyancy aid in the experimentation is toppled over or enters liquid after the submergence fully and change the weight of buoyancy aid.
4, the experiment physical quantity of surveying all can directly be read, and convenient experimental operation, saves time, accurately.
Description of drawings:
Fig. 1 is liquid pressure and depth relationship tester one-piece construction view.
Embodiment is further described below in conjunction with accompanying drawing.
Show liquid pressure and depth relationship tester by Fig. 1 integral body, it is a knapsack 1 of being made the transparent body by plastic material, the buoyancy aid 2 that comprises the flat cylindrical body of configuration, and the mass 3 that fixedly installs of buoyancy aid 2 inner bottom parts, the outer wall of buoyancy aid 2 be provided with one row can indicate the scale sign 4 of buoyancy aid submergence, and help read to encircle 5 and microdynamometer 6 combine.Described buoyancy aid 2 adopts totally enclosed flat cylindrical body, and its interior bottom portion is provided with the mass that the bigger metal material of density is made, and the ratio that makes its buoyancy aid 2 maximum displaced weights and himself weight was near 1: 1; Help read to encircle 5 it have an interior annular distance that matches with buoyancy aid 2 external diameters, outer shroud is the convex-concave shape, integral body be a density less than 1, the board that color is eye-catching.
Described microdynamometer 6, it is by a row is set on dynamometer body and the body at least the scale 7 that shows weight to be arranged, and is made up of part device one spring 8 wherein and the hook that has.
During experiment, with floorage is on the hook that has of spring 8 that the buoyancy aid 2 of S utilizes the boss hole on top to hang on microdynamometer 6, at first read the weight G of buoyancy aid 2 self, then buoyancy aid 2 is immersed any degree of depth of liquid in the transparent knapsack 1, directly or by helping read to encircle 5 and read buoyancy aid 2 submergence H and dynamometer 6 indicating value Fo, the buoyancy F=G-Fo that makes progress of buoyancy aid 2 bottoms institute liquid body then, pressure P=F/S=(G-Fo)/S that buoyancy aid 2 bottoms institute liquid body makes progress.Change buoyancy aid 2 submergences, promptly verify the relation of liquid pressure P and depth H from above experiment.
Experimental example: research liquid pressure and depth relationship experiment, choose buoyancy aid deadweight G=80g, floorage S=707mm
2, the dynamometer maximum is weighed as 100g, minimum sensibility reciprocal is 1g, five experiments to survey data as follows:
| Experiment number | Buoyancy aid immersion liquid depth H=(mm) | The different depth lower spring claims indicating value Fo (g) | The buoyancy aid bottom liquid body upward pressure F=G-Fo of institute (g) | The buoyancy aid bottom institute liquid body pressure P=F/S that makes progress |
| 1 | 30 | 58 | 22 | 0.031 |
| 2 | 40 | 51 | 29 | 0.041 |
| 3 | 50 | 44 | 36 | 0.051 |
| 4 | 60 | 37 | 43 | 0.061 |
| 5 | 70 | 30 | 50 | 0.071 |
By analysis, can obviously verify out the direct proportion linear relationship of the liquid pressure and the degree of depth to above experimental data.
