Abstract
A thermodynamic circulation teaching demonstrator comprises a transparent cuboid cavity, wherein a smoke producing device is arranged in the cuboid cavity, a heating device is arranged at one side of the bottom of the cuboid cavity, a refrigeration device is arranged at the other side of the bottom of the cuboid cavity, a cover board which can be opened is arranged at the top of the cuboid cavity, a through hole is formed in the cover board and can be opened or closed by a piston. The thermodynamic circulation teaching demonstrator realizes demonstration of difficult points in middle school geographical teaching, students can have deep impression on the difficult points; and besides, suitable material is easy to manufacture and search.
Description
Technical field
The utility model relates to a kind of thermodynamic circulation demonstration instrument for teaching.
Background technology
Although teaching material has been demonstrated the ultimate principle of the thermodynamic circulation that causes uneven in temperature to the student, simultaneously, teaching material is also set forth the forming process of principle.But Most students can not be goed deep into the understanding of demonstration and principle.And, the relevant knowledge of thermodynamic circulation and air motion be in college entrance examination Chang Kaodian, must examination point and backbone knowledge, this part knowledge is also to explain the important knowledge of relevant air motion, environmental pollution in life.Because the space is more abstract, the student is difficult to set up spatial impression, and how no matter the teacher lecture, and student's total marks of the examination are all very undesirable.The difficult situation that causes the difficult religion of teacher, student to find it difficult to learn.If can design demonstration equipment, better demonstrate the teaching material principle, allow the student deeply understand principle, just can improve operational capability and total marks of the examination, obtain more relevant knowledge.
The utility model content
The utility model fundamental purpose is to provide a kind of thermodynamic circulation demonstration instrument for teaching simple in structure.
The technical scheme that the utility model adopts is: a kind of thermodynamic circulation demonstration instrument for teaching, comprise a transparent rectangular parallelepiped cavity, be provided with smoking device in the rectangular parallelepiped cavity, be provided with heating arrangement on one side in the rectangular parallelepiped cavity bottom, be provided with refrigerating plant at rectangular parallelepiped cavity bottom another side, rectangular parallelepiped cavity top is provided with cover plate, and cover plate can be opened, cover plate is provided with perforation, and perforation can open or close perforation by piston.
Be further, described refrigerating plant is drawer one, can open and put into ice cube, and described heating arrangement is drawer two, can open and put into hot-water bottle.
Further that described heating arrangement is the device that resistance wire is installed and is communicated with power supply.
Be further, described smoking device is santal, preferably adopts the smog pen that can send colored cigarette.
Further that for better allowing the student clearly see the demonstration effect clearly in demonstration, after the rectangular parallelepiped cavity inside, the back side is provided with rotating minute surface.
Be further, be provided with illuminating lamp on transparent rectangular parallelepiped cavity inside both sides, more can be clear that the flow direction of flue gas turn on like this lamp in presentation process after.
During demonstration, first heating arrangement and refrigerating plant are opened, then opened cover plate, put into smoking device, adjust the minute surface at the back side, open illuminating lamp, cover cover plate.A little while, just can obviously see flowing to refrigeration one end from heating an end at transparent rectangular parallelepiped cavity top of flue gas, and flow to heating one end from the end that freezes at transparent rectangular parallelepiped cavity bottom flue gas.
The beneficial effect of this thermodynamic circulation demonstration instrument for teaching is: used simple and practical method to realize the difficult point demonstration in the middle school teaching, can descend deep impression can for the student, and selection has been easy to make and seek.
Description of drawings
Fig. 1 is thermodynamic circulation demonstration instrument for teaching structural representation.
Be numbered in figure: long body cavity 1, smoking device 2, drawer 1, drawer 24, cover plate 5, perforation 6, piston 7, minute surface 8, illuminating lamp 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, the utility model thermodynamic circulation demonstration instrument for teaching, comprise one by organic glass by being bonded transparent rectangular parallelepiped cavity 1, rectangular parallelepiped cavity 1 top is cover plate 5, cover plate 5 can closely cover on rectangular parallelepiped cavity 1, also can take away from rectangular parallelepiped cavity 1, be used for putting into smoking device 2, smoking device adopts the smog pen, after the stamen of lighting the smog pen, put in rectangular parallelepiped cavity 1, and cover cover plate 5, when the interior cigarette of rectangular parallelepiped cavity 1 is more, can open the piston 7 on cover plate, perforation 6 is opened, emit partial fume.After rectangular parallelepiped cavity 1 is inner, the back side is minute surface 8, and minute surface 8 is rotationally connected by the organic glass on hinge and rectangular parallelepiped cavity 1 both sides.
Rectangular parallelepiped cavity 1 bottom is drawer 1 on one side, is used in drawer 1 placing ice cube, and be drawer 24 at rectangular parallelepiped cavity 1 bottom another side, be used for placing hot-water bottle in drawer 24.Open the illuminating lamp 9 on rectangular parallelepiped cavity 1 both sides, adjust simultaneously minute surface 8, through after a while, can see significantly that flue gas flows to placing ice cube from placing hot-water bottle at rectangular parallelepiped cavity 1 top on one side, in rectangular parallelepiped cavity 1 bottom counter current.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have change and change.All within spirit of the present utility model and principle, any modification of doing, improvement etc. are within all should being included in protection domain of the present utility model.
