Abstract
The utility model relates to physical teaching appliances in middle schools, in particular to a liquid buoyance and pressure intensity test demonstrator. The liquid buoyance and pressure intensity test demonstrator comprises a water sink, and is characterized in that a buoyance tube is arranged in the water sink and is a tube with one end closed and one end open, a weight is mounted in the buoyance tube, and an end cap is arranged at the open end of the buoyance tube. The liquid buoyance and pressure intensity test demonstrator without complicated and expensive tools such as a balance, a test tube and a graduated scale is simple in structure, convenient to use and favorable for simplifying test steps and enabling students to acquire relevant knowledge as soon as possible.
Description
Technical field
The utility model relates to physical teaching aid for middle school, specifically a kind of liquid buoyancy pressure intensity testing demonstrator.
Background technology
Need to verify by experiment the relation of liquid internal pressure and the degree of depth in the junior middle school physics teaching, and the proportion, buoyancy etc. that calculate liquid.To use the multiple types of tools such as balance, test tube, rule in the test, complex operation, experimental assembly complexity, experiment effect is not good.
Summary of the invention
The purpose of this utility model provides a kind of liquid buoyancy pressure intensity testing demonstrator simple in structure, easy to use, can demonstrate well the relation of liquid internal pressure and the degree of depth, and proportion, buoyancy by simple Conversion Calculation liquid, be conducive to the very fast grasp relevant knowledge of student.
The utility model is that the technical scheme that the technical solution problem adopts is:
Liquid buoyancy pressure intensity testing demonstrator described in the utility model, comprise tank, it is characterized in that: be provided with buoyancy tube in the described tank, described buoyancy tube is the body that an end seals an end opening, counterweight is housed in the buoyancy tube, and the openend of buoyancy tube is provided with end cap.
Be provided with depthometer on the sidewall of described tank.
After adopting technique scheme, this liquid buoyancy pressure intensity testing demonstrator has omitted the instruments such as the balance, test tube, rule of complex and expensive, simple in structure, easy to use, omitted the instrument such as balance, test tube, rule of complex and expensive, be conducive to simplify experimental procedure, make the student grasp as early as possible relevant knowledge.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
As shown in Figure 1, liquid buoyancy pressure intensity testing demonstrator described in the utility model comprises tank 1, is provided with depthometer 5 on the sidewall of tank 1, is convenient to observe the degree of depth of water in the tank.Be provided with buoyancy tube 2 in the described tank 1, described buoyancy tube 2 is bodys that an end seals an end opening, is provided with scale on the sidewall of buoyancy tube 2, is convenient to observe buoyancy tube 2 and does not have length in the entry.For ease of calculating, the sectional area of buoyancy tube 2 can be designed to standard size, such as 1 square centimeter, the weight of buoyancy tube 2 also is designed to the weight of standard, such as 10 grams.Counterweight 3 is housed in the buoyancy tube 2, and the openend of buoyancy tube 2 is provided with end cap 4, can be with buoyancy tube 2 sealings.
During use, the counterweight of Different Weight is put in the buoyancy tube 2, do not had length in the entry by observing buoyancy tube 2, can verify the relation of liquid internal pressure and the degree of depth, perhaps calculate the proportion, buoyancy of liquid etc.
