Embodiment Construction

[0006] Now with reference to accompanying drawing, be described as follows in conjunction with embodiment: Photosensitive solar altimeter of the present invention, as shown in the figure, respectively drills a 5mm diameter two ends of a circular, transparent, closed vessel with a diameter of 140mm thick 20mm The circular hole is made into a liquid disk 1, and a stretchable metal tube 2 with a diameter of 5 mm and a length of 180 mm is inserted into the two circular holes of 1, and a photosensitive tube is placed in the end of the metal tube 2 passing through the two circular holes of 1 3. Connect the circuit board 4 with the music chip to the positive and negative poles of the battery 7, the positive and negative poles of the photosensitive tube 3, the positive and negative poles of the diode 6, and the two ends of the speaker 5, and inject a slightly colored The liquid (water) of injecting liquid (water) is level with the metal tube 2 after closing both ends with glass glue to...

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 [0001] The invention relates to a teaching aid, in particular to a solar altimeter, which belongs to the technical field of teaching instruments. Background technique [0002] Sun altitude is the angle between the sun's rays and the horizon. When measuring the height of the sun, most of the original technologies use manual adjustment of the instrument’s horizontal state, which has the disadvantages of being inconvenient to operate and affecting the measurement results; in addition, the original technology only provides measurement methods and means, but does not reveal the conceptual depth of the sun’s height Connotation. Contents of the invention [0003] The present invention utilizes the liquid in the liquid pan to fully demonstrate the existence of a water level under the action of gravity. The light-through tube in the present invention can pass through the liquid plate to receive sunlight, and the length can be adjusted according to the intensity of...
