Abstract
The utility model provides a device for showing wind formation, belonging to such fields as physics, education, cryptology, display, advertisement, seal (education or demonstration tool), model, planetarium, tellurion, map, charts, group technology field of physics, etc. In particular, the utility model relates to a device for showing wind formation. The device also can be a tool for teaching or communicating with the blind, the deaf, the mute. The device for showing wind formation features simple structure, simple usage, and clear demonstration. The device comprises a top-opened demonstration box and an external circuit, with structural key point lying in that one side of the demonstration box bottom is provided with a lamp socket connected with the external circuit, with a bulb arranged upon the socket while the other side of the demonstration box bottom is provided with a vane, with a circular hole arranged in the outer wall of the demonstration box close to the vane.
Description
Technical field
The utility model is to belong to physical piece, education; Cryptology; Show; Advertisement; The big class of seal, education or demonstration equipment; Be used to the apparatus of imparting knowledge to students or communicating by letter with blind person, deaf person or mute; Model; Planetarium; Terrestrial globe; Map; The figure watch group, physical little technical group field, the formation demonstration device of more specifically saying so and relating to wind.
Background technology
In the existing junior-senior high school geography teaching material, about knowledge such as zone of pressure, wind bands, especially the formation of wind is very important, for the study of follow-up course bigger influence is arranged.Because therefore this part knowledge abstraction, difficult understanding need the teaching of use apparatus to come assisted learning in teaching.
At present, mainly be to use apparatus such as wall chart,, be not easy to understand though can make things convenient for the student to remember at the teaching of the formation of wind part.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of formation demonstration device of simple in structure, easy to use, the tangible wind of demonstrative process is provided.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises demonstration box and the external circuit that the top is uncovered, and a side of its structural feature demonstration box bottom is provided with the lamp socket that links to each other with external circuit, and lamp socket is provided with bulb; The opposite side of demonstration box bottom is provided with weathervane, and the demonstration box outer wall of close weathervane is provided with circular hole.
External circuit comprises power supply, switch and slide rheostat, and described power supply, switch and slide rheostat are connected successively.
The demonstration box outer wall is made by clear glass.
The beneficial effects of the utility model:
(1) simple in structure, easy to use
The utility model comprises demonstration box and the external circuit that the top is uncovered, and a side of its structural feature demonstration box bottom is provided with the lamp socket that links to each other with external circuit, and lamp socket is provided with bulb; The opposite side of demonstration box bottom is provided with weathervane, and the demonstration box outer wall of close weathervane is provided with circular hole; Therefore the utility model structure is very simple.
Bulb links to each other with the external circuit that is in series by power supply, slide rheostat and switch, controls bulb by external circuit in Demonstrator Trials, and then the control experiment condition, and is very easy to use.
(2) good demonstration effect, phenomenon is obvious
This use is novel controls the bright degree of bulb by external circuit, and then controls the heating situation of bulb, makes that the temperature in the demonstration device changes, thereby causes the variation of air pressure in the demonstration device, causes the formation of wind.
The utility model good demonstration effect, phenomenon is obvious, and the student that is more convenient for understands the formation of zone of pressure, wind band, therefore more profoundly understands relevant geographical knowledge.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing, 1 is switch, and 2 is slide rheostat, and 3 is external circuit, and 4 is power supply, and 5 is lamp socket, and 6 is bulb, and 7 is weathervane, and 8 is circular hole, and 9 is demonstration box.
Embodiment
The utility model comprises demonstration box 9 and the external circuit 3 that the top is uncovered, and a side of demonstration box 9 bottoms is provided with the lamp socket 5 that links to each other with external circuit 3, and lamp socket 5 is provided with bulb 6; The opposite side of demonstration box 9 bottoms is provided with weathervane 7, and demonstration box 9 outer walls of close weathervane 7 are provided with circular hole 8.
For the demonstration effect is observed easily, demonstration box 9 outer walls are made by clear glass.
Below in conjunction with accompanying drawing course of action of the present utility model is described:
The air expanded by heating in space, somewhere, rising, density reduce, pressure descends, and cold air density height on every side, pressure are big, and just cross-current comes to replenish---form wind.
During class demonstration, energized 4 is opened switch 1, and moments later, observe phenomena can see that weathervane 7 begins to rotate, and direction is just towards circular hole 8 places; Reconcile slide rheostat 2, observe phenomena changes, and bulb 6 is bright more, and weathervane 7 dancings are obvious more; Bulb 6 is dark more, and weathervane 7 amplitudes of fluctuation are more little.
