Description
Technical field
The utility model is related to a kind of Middle School Physics teaching aid, specifically a kind of demonstration apparatus for energy conversion.
Background technology
In Middle School Physics energy conversion conservation course learning, kinetic energy, potential energy are more difficult.In order to get information about
Transfer process, needs to use presentation tool in learning process, general to be demonstrated using the small ball test of swash plate, its simplified process
It is：Bead is rolled to flat board from the high-end of swash plate, and flat board one end is provided with spring, and bead is rolled into compression spring at spring, so that
Classmate is allowed to observe action potential conversion.
A kind of teaching aid is disclosed in patent 201420687971.3, can intuitively demonstrate elastic potential energy and kinetic energy it
Between conversion, but mechanical energy also includes the gravitional force most often occurred in addition to kinetic energy and elastic potential energy, makes in actual learning
During, it is impossible to demonstrate the conversion of gravitional force and other energy.
The content of the invention
The utility model provides a kind of demonstration apparatus for energy conversion, and simple in construction, easy install makes, can intuitively demonstrated
Conversion between kinetic energy, elastic potential energy and gravitional force.
The utility model use concrete technical scheme be：A kind of demonstration apparatus for energy conversion, including：
Cylinder, its two ends, which has, sets symmetrical annular groove and bobbin winoler on connecting portion, cylinder；
Two covers, are connected with cylinder two ends connecting portion respectively, and each cover is provided with two hanging holes；
Demonstration portion, is detachably connected with cylinder or cover；
Guide rail, is matched with annular groove on cylinder.
The demonstration portion includes India rubber bar and weight, and India rubber bar is X-shaped, and end is hung provided with hook, weight
Mounted in the cross part of India rubber bar.
The demonstration portion includes hanging wire and weight, and hanging wire is 2, and length is identical with shape, and hanging wire one end is pacified by linking up with
On bobbin winoler, other end connection weight, and be wrapped on bobbin winoler.
The cover is used with cylinder to be engaged or is threadedly coupled.
The cylinder is transparent or opaque.
The utility model advantage is：Simple in construction, convenient disassembly, using transparent cylinder can intuitive and convenient demonstration kinetic energy,
The transfer process of elastic potential energy and gravitional force, and demonstration portion is freely changed according to demonstration situation, results of learning are good, and forging
Refine the manipulative ability of student.

Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.
Embodiment one
As shown in Figure 1 and Figure 2, a kind of demonstration apparatus for energy conversion, will first connect the two ends of weight A5 India rubbers bar 4
Hung over by hook 6 on two hanging holes 7 of a cover 2, and cover 2 is engaged with cylinder 1, it is then that India rubber bar 3 is another
Outer two ends hang on the hanging hole 6 of another cover 2 and engaged.Hanging wire 7 is connected on bobbin winoler 9, the connection of the end of seton device 9
Weight B11.Teaching aid is placed on guides 3, annular groove 8 is engaged with guide rail 3.
When the present embodiment is demonstrated, rolling barrel 1 on guides 3, due to weight A5 effect, India rubber in rolling process
Bar 4 is tightened, and hanging wire 10 is wrapped on bobbin winoler 9, when kinetic energy is zero, the release elastic potential energy of India rubber bar 4, weight
B11 discharges gravitional force, and cylinder 1 is rolled round about.
Another operational version is：Hanging wire 10 is all wound, cylinder 1 is discharged under inactive state, in cylinder 1 in weight
Roll on themselves under B11 Action of Gravity Field, and India rubber bar 4 is tightened, after weight B11 is located at minimum point, India rubber bar 4 is released
Elastic potential energy is put, cylinder 1 is rolled round about.
Embodiment two
As shown in figure 3, the present embodiment and embodiment one are essentially identical, difference be to pull down India rubber bar 4 with again
Thing A5, the conversion of kinetic energy and gravitional force can be demonstrated merely.
When the present embodiment is demonstrated, rolling barrel 1 on guides 3, hanging wire 10 is wrapped on bobbin winoler 9, when kinetic energy is zero
When, weight B11 release gravitional force, cylinder 1 is rolled round about.
Embodiment three
As shown in figure 4, the present embodiment and embodiment one are essentially identical, difference is to pull down hanging wire 10 and weight B11,
The conversion of kinetic energy and elastic potential energy can be demonstrated merely.
When the present embodiment is demonstrated, rolling barrel 1 on guides 3, India rubber bar 4 is tightened in rolling process, when kinetic energy is
When zero, the release elastic potential energy of India rubber bar 4, cylinder 1 is rolled round about.
