Abstract
The invention discloses a sun height measuring instrument, which belongs to the technical field of teaching instruments. The measuring instrument comprises a liquid disk, water, a light path tube, a light sensor, a circuit board, a trumpet, a diode, a battery, a bracket, an angle gauge and the like, wherein the light path tube passes through the liquid disk and is pulled in an adjustable and telescopic way; the liquid disk can be filled with liquid; when the liquid disk is rotated with a hand, the light path tube can be driven to rotate; and after the light sensor in the light path tube receives solar rays, light emitted by the diode can be seen and a music sound can be heard. The presence of a horizontal plane can be felt institutionally and the horizontal plane does not change along with the influences of an individual motion object and the ground situation. During measurement, the included angle relation between solar rays and the horizontal ground can be reflected and the measuring instrument is not influenced by a measuring place and is easy and convenient to operate. On the other hand, the light path tube verifies linear transmission of light; moreover, when the measuring result is recorded, the diode emits light and music is played automatically for promoting.
Description
Technical field
The present invention relates to a kind of teaching aid, particularly a kind of altitude of the sun measuring instrument belongs to technical field of teaching instruments.
Background technology
Altitude of the sun is meant the angle between sunray and the ground level.When measuring altitude of the sun, the most manual adjustments instrument horizontalitys that adopt of original technology have the not only inconvenient shortcoming of operating but also influencing measurement result; Original in addition technology has only provided measuring method and means, and does not deeply disclose the conceptual deep layer intension of altitude of the sun.
Summary of the invention
The present invention utilizes the liquid in the described liquid dish, has fully showed the existence of action of gravity lower horizontal plane.Logical light pipe can pass the liquid dish and be used for receiving sunray described in the present invention, and flexible according to the strong and weak adjustable length pulling of light.When rotating the moving logical light pipe of liquid dribbling by hand and on support, rotating together, promptly can produce angle between liquid level in logical light pipe and the liquid dish, after sunray enters logical light pipe, photoreceptor will energized be seen led lighting in the logical light pipe, loudspeaker send rhythmical music sound simultaneously, and at this moment the throughput hornwork number of degrees just can be learnt altitude of the sun at that time.The present invention can allow the existence of student's direct feel to surface level, and to realize surface level be not change because of the influence of indivedual moving objects and surface state, more can represent between sunray and the level ground angle during measurement and concern, and then disclose altitude of the sun concept nature intension.The present invention is not measured the place to be influenced, easy and simple to handle; On the other hand, described logical light pipe has been verified the rectilinear propagation of light; Led lighting and the automatic prompting of hearing musical sound during the record measurement result, can be seen in the aspect again, can excite student's learning interest, teach through lively activities.
Description of drawings
Accompanying drawing is the structural representation of sensitization altitude of the sun measuring instrument of the present invention.
Among the figure: 1 is the liquid dish, and 2 are logical light pipe, and 3 is photoreceptor, and 4 is circuit board, and 5 is loudspeaker, and 6 is diode, and 7 is battery, and 8 is support, and 9 is protractor.
Embodiment
Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: sensitization altitude of the sun measuring instrument of the present invention, as shown in the figure, circle with a thick 20mm of diameter 140mm, transparent, the circular hole of a 5mm is respectively bored at the diameter two ends of sealing vessel, make liquid dish 1, one section diameter 5mm, the telescopic metal tube 2 of long 180mm penetrates in two circular holes of 1, in metal tube 2 these ends that pass 1 liang of circular hole, place a sensitizing tube 3, and will have the circuit board 4 of Music Clip and the both positive and negative polarity of battery 7, the both positive and negative polarity of sensitizing tube 3, the two ends of the both positive and negative polarity of diode 6 and loudspeaker 5 are connected, in 1, inject the slightly liquid of color (water), the liquid level that injects liquid (water) does not allow liquid (water) leak outside with metal tube 2 equal backs with glass cement sealing two ends, wherein any one sidewall on the outer wall of the two sides of circular dishware 1 is fixed a protractor 9, realize that protractor 9 straight angle limits overlap with metal tube 2 and liquid (water) face three, and all pass the center of circle of circular dishware 1, at last the circular dishware 1 that has metal tube 2 and protractor 9 is stood up, be clipped on the support 8 of base, rotate at hand under the operation of circular dishware 1, can allow metal tube 2 rotate 180 degree from left to right.
