Abstract
The utility model discloses a solar altitude measuring instrument, comprising a chassis (1), an upright rod (3) movably connected with the center of the chassis (1), and an angle board (4) connected with a projector. The surface of the chassis (1) is provided with an azimuth dial, scale, and a compass (2). The projector comprises a rotary rod (5), and a projection hole (7) and an image screen dot (8) fixed on the rotary rod (5) from top to bottom. Planes where the projection hole (7) and the image screen dot (8) are in are disposed parallelly. The lower end of the rotary rod (5) is connected with the angle board (4) with the scale through a rotating shaft. The upper end of the rotary rod (5) is provided with a pointer (6) pointing at the scale on the angle board (4). Beneficial effects of the solar altitude measuring instrument are simple operation, visual results, low measurement errors, and the instrument is multipurpose.
Description
Technical field
The utility model relates to for a kind of measurement mechanism in the teaching of primary school nature course, particularly a kind ofly completes the sun and shadow, vertical rod projection, measures the altitude of the sun measuring instrument of the experiments such as altitude of the sun.
Background technology
Measuring altitude of the sun is an important experiment in primary school nature course, the method of existing measurement altitude of the sun mostly is drawing, on level ground, put an ancient Chinese sundial, measure the length of Gui pin, measure the length of Gui pin shadow, the shadow of Gui pin and Gui pin of take is set up right-angle triangle as two right-angle sides, with protractor, measure the angle of the corresponding acute angle of Gui pin, this angle altitude of the sun that Here it is at that time, not easy with this measurement altitude of the sun method operation, need to draw and angulation, easily occur larger error, result shows directly perceived not.
Utility model content
The defect existing in method for existing measurement altitude of the sun, the utility model provides a kind of altitude of the sun measuring instrument.
To achieve these goals, technical solution adopted in the utility model is:
A kind of altitude of the sun measuring instrument, comprise chassis and be movably connected in the vertical rod of center chassis and be connected with the angle board of projector, the card on chassis is provided with dumb card, scale mark and compass, projector comprises bull stick and is fixed on successively projection hole and the shadow screen round dot on bull stick from top to bottom, projection hole and shadow screen round dot place plane parallel arrange, the lower end of bull stick is connected on the angle board with scale by rotating shaft, and the upper end of bull stick is provided with the pointer of orientation angle plate high scale;
Described vertical rod and angle board are movably connected in center chassis by the mode of pegging graft;
Described center chassis is provided with jack, and the end of vertical rod and angle board is provided with the latch matching with jack.
On chassis, be also provided with level meter.
The beneficial effects of the utility model: without picture, can directly read altitude of the sun at that time, simple, intuitive from instrument; Owing to not needing to draw and angulation, measuring error is little; Instrument of many uses, can be used for the sun and shadow, vertical rod projection, measures the experiments such as altitude of the sun, a multi-purpose instrument.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Embodiment
A kind of altitude of the sun measuring instrument, comprise chassis 1 and the vertical rod 3 and the angle board 4 that is connected with projector that are movably connected in 1 center, chassis, the card on chassis 1 is provided with dumb card, scale mark and compass 2, projector comprises bull stick 5 and is fixed on successively projection hole 7 and the shadow screen round dot 8 on bull stick 5 from top to bottom, projection hole 7 and shadow screen round dot 8 place plane parallel arrange, the lower end of bull stick 5 is connected on the angle board 4 with scale by rotating shaft, and the upper end of bull stick 5 is provided with the pointer 6 of orientation angle plate 4 high scales; Described vertical rod 3 and angle board 4 are movably connected in 1 center, chassis by the mode of pegging graft; 1 center, described chassis is provided with jack, and the end of vertical rod 3 and angle board 4 is provided with the latch matching with jack.
The utility model can complete the sun and shadow, vertical rod projection, measure the experiments such as altitude of the sun.1, for the experiment of the sun and shadow, experimentation is: first chassis is put on level ground in the sun, slowly rotating chassis, is that direct north is pointed in the compass arctic in dish; Then in the jack at card center, insert vertical rod, with ruler, measure and record length and the orientation of shadow.
2,, for the experiment of measuring altitude of the sun, can adopt drawing or sciagraphy to measure.Experimentation is as follows:
In drawing, first, chassis is put on level ground in the sun, slowly rotating chassis, is that direct north is pointed in the compass arctic in dish; In the jack at card center, insert vertical rod; Then, with ruler, measure the length from top to card of vertical rod and length the record of shadow; Rotating chassis slowly, makes shadow overlap with the length line in card again, reads the right value of shadow length, is used for the shadow error in length that calibration measures with ruler; Finally, take the effective length of vertical rod and the length of shadow as two right-angle sides build right-angle triangle, with protractor, measure the angle right with the right-angle side of vertical rod effective length, this angle is the height of the sun.
In sciagraphy, first chassis is put on level ground in the sun, slowly rotating chassis, is that direct north is pointed in the compass arctic in dish; Then in the jack of center chassis, insert angle board, the projector on rotational angle plate slowly, make to overlap with the shadow screen round dot on projector by the round dot of projection hole when sunlight, now the pointer of projector upper end indicated scale on angle board is exactly altitude of the sun now.
Student can also be in 1 year the Spring Equinox, the Summer Solstice, the Autumnal Equinox and Winter Solstice etc. four solar term the altitude of the sun of this day positive period of the day from 11 a.m. to 1 p.m, record result, analyze the four seasons origin cause of formation.
The beneficial effects of the utility model: without picture, can directly read altitude of the sun at that time, simple, intuitive from instrument; Owing to not needing to draw and angulation, measuring error is little; Instrument of many uses, can be used for the sun and shadow, vertical rod projection, measures the experiments such as altitude of the sun, a multi-purpose instrument.
