Abstract
The utility model relates to a teaching apparatus, specifically relates to a magnetic suspension wind wheel, and helps to solve the problem that since conventional apparatuses cannot show the theory of magnetic suspension in a vivid and interesting manner, the teaching quality of a physics class is influenced. The magnetic suspension wind wheel comprises an apparatus support. The center of a circular hole above the apparatus support is provided with a wind wheel shaft with a rotation annular magnet. The lower end of the wind wheel shaft is supported by a wind wheel shaft support frame. The wind wheel shaft is provided with the wind wheel. The upper end of the wind wheel shaft is suspended in the center of the circular hole by the repulsive force of the same pole magnetic fields of the three fixation strong magnets and the rotation annular small magnet. The bottom of the apparatus support is provided with a small motor, a cell box and a power switch, wherein the cell box and the power switch are matched with the small motor. The upper end of the rotation shaft of the small motor is provided with a propeller. According to the magnetic suspension wind wheel, the production process and operation are simple; the structure is reasonable; and demonstration effect is vivid and interesting, thereby helping to excite the learning interest of students, and improve the teaching quality in the physics class.
Description
Technical field
The utility model relates to a kind of instruments used for education, is specially a kind of magnetic suspension wind wheel.
Background technology
Teaching aid is as the instrument of teacher's aided education, there is the irreplaceable effect of other means, classroom teaching is used the excellence of demonstration effect and interesting teaching aid in good time, can motivate students' interest in learning, the learning initiative of mobilizing students, outstanding focal points, break through teaching difficulty, optimize classroom structure, the ability of creative of Developing Students ', effectively improves the quality of teaching and efficiency.
In Middle School Physics teaching, existing instrument can not carry out the lecture experiment of vivid and interesting to maglev scientific knowledge at present, and the weak effect of demonstration is unfavorable for exciting student's interest and improves physics lesson quality of instruction.
Summary of the invention
The utility model can not carry out problem visual in image, vivid and interesting experimental demonstration in order to solve in present physical teaching course teaching aid used in particularly magnetic levitation factor chapters and sections, and a kind of magnetic suspension wind wheel is provided.
The utility model is to adopt following technical scheme to realize: magnetic suspension wind wheel comprises instrument support (7), the circular hole center device of instrument support (7) top is with the rotor shaft (4) of rotary annular magnet (5), the lower end of rotor shaft (4) is supported by rotor shaft bracing frame (9), on rotor shaft, device has wind wheel (8), upper end by three fixedly the repulsive force of the homopolar field of strong magnet (6) and rotary annular small magnet (5) be suspended in circular hole center, the bottom device small machine (2) of instrument support, and the battery case supporting with it (1) and power switch (10), small machine rotating shaft device for upper end screw propeller (3).
The utility model utilizes rotary annular magnet and the fixing mutual repulsive force in magnetic field of strong magnet, make wind wheel rapidly interesting experiment of rotation under suspended state, vivid and interesting, disclose maglev the principles of science visual in imagely, demonstration effect vivid and interesting, visual in image, contribute to improve student's learning interest, excite student's creativity consciousness, student is expressly understood and grasps securely knowledge, its compact conformation, advantages of simple, flexible and convenient operation, preserve easy to carry, there is the impayable superiority of existing promulgated by the State Council instrument, have good value for applications.
Accompanying drawing explanation
Accompanying drawing is the utility model basic structure front plan view;
In figure: 1, battery case; 2, small machine; 3, screw propeller; 4, rotor shaft; 5, rotary annular small magnet; 6, fixing strong magnet; 7, instrument support; 8, wind wheel; 9, rotor shaft bracing frame; 10, power switch.
Embodiment
Magnetic suspension wind wheel, comprise instrument support (7), the circular hole center device of instrument support (7) top is with the rotor shaft (4) of rotary annular magnet, the lower end of rotor shaft (4) is supported by rotor shaft bracing frame (9), on rotor shaft, device has wind wheel (8), upper end by three fixedly the repulsive force of the homopolar field of strong magnet (6) and rotary annular small magnet (5) be suspended in circular hole center, the bottom device small machine (2) of instrument support, and the battery case supporting with it (1) and power switch (10), small machine rotating shaft device for upper end screw propeller (3).
Examination on experimental operation:
