Description

Phases of the moon origin cause of formation exploring instrument

Technical field

The utility model relates to a kind of instruments used for education, is specially a kind of phases of the moon origin cause of formation exploring instrument.

Background technology

Immense universe has been full of mystery and secret, the rotation that scientists of all times has confirmed the circumsolar revolution of the earth and itself for a long time the spring, summer, autumn and winter throughout the year, the environment for human survival at daytime and night, and the moon is the rule revolution in cycle with the moon around the earth, make people observe the reflected light that the moon comes from the sun, promptly be referred to as the spontaneous phenomenon of crescent or half moon, first quarter moon, full moon, crescent or the lunar eclipse etc. of " phases of the moon ".In order to guide the understanding of juvenile student to universe, instructors must be taught knowledge about celestial body to them, comprises also wherein that certainly the phases of the moon origin cause of formation says.Yet, in present geographical teaching of primary and middle school, it generally is the rule of explaining moon phase change by figure, and do not have visual pattern the demonstration moon phase change instrument, therefore the student is difficult to the phases of the moon diagram in observed phenomenon and the textbook in the night sky of being everlasting day is united, and is unfavorable for that the student understands, grasps relevant knowledge.

Summary of the invention

The utility model provides a kind of phases of the moon origin cause of formation exploring instrument in order to solve the instrument that not have special demonstration moon phase change in the existing geographical teaching of primary and middle school, to be unfavorable for that the student understands, grasps the problem of relevant knowledge.

The utility model is to adopt following technical scheme to realize: phases of the moon origin cause of formation exploring instrument, comprise casing, be provided with the dividing plate that is divided into preceding casing and rear box in the casing, run through on the dividing plate that setting is located on the dividing plate by bearing bracket stand and by the rotating shaft of driving mechanisms control, be fixed with first moon rotating disk of casing before being positioned in the rotating shaft, first moon disk edge is fixed with moon model, first moon rotating disk periphery is provided with the instrument chassis that is fixed on the dividing plate, the instrument chassis circumferential interval is provided with phases of the moon title pilot lamp, the corresponding power contact that is arranged on the dividing plate of each phases of the moon title pilot lamp is fixed with a power supply contact that can contact with power contact in the rotating shaft; Preceding casing below is provided with hollow boss, be fixed with support on the boss, the support upper end is installed with the terrestrial globe that is positioned at preceding casing and is in first moon center of turntable position, assembly tube perpendicular to first moon rotating disk is set in the terrestrial globe, set gradually 45o level crossing and convex lens in the assembly tube from inside to outside, in the convex lens outsides and be positioned at and be provided with the frosted glass imaging screen that connects with the assembly tube on the terrestrial globe; Before in the casing and be positioned at the source of parallel light assembly that the one side setting of first moon rotating disk is made of 45o plane mirror, one group of condenser and light source, wherein one group of condenser and light source from top to bottom are arranged in the boss, on the guide pole before the 45o plane mirror is movably installed in and is fixed in the casing.Described light source can be the 300W bromine tungsten filament lamp of discarded projector; The driving mechanism of described rotating shaft can be made of small machine, belt pulley and travelling belt.

Be provided with second moon rotating disk that is installed in the rotating shaft in the described rear box, second moon disk edge is fixed with moon figure by movable axis, is fixed with sagging iron nail on the movable axis, and the rotating shaft end is fixed with earth figure; Rear box one side is fixing to connect the sun graphic that constitutes by two fan semicircular plates by hinge.

Adopt structural design of the present utility model, preceding casing is " outdoor scene simulation ", comprise the ground moon model that drives with small machine, by the source of parallel light assembly of 300W bromine tungsten filament lamp and multilayer condenser and plane mirror combination, and by the phases of the moon image-forming assembly of level crossing, convex lens and the combination of frosted glass imaging screen and phases of the moon title pilot lamp etc.Preceding casing effect is to make the student to obtain perceptual knowledge, with strong source of parallel light component tracks irradiation " moon " (moon model) around " earth " (terrestrial globe) rotation, by phases of the moon image-forming assembly " moon " is presented on the frosted glass imaging screen on the terrestrial globe in the phases of the moon (crescent or half moon, first quarter moon, full moon, crescent or lunar eclipse etc.) in each orientation, vivid, directly perceived, interest all makes existing instrument too far behind to catch up.Obtain the student on the basis of sufficient perceptual knowledge, it is rational knowledge that " activity diagram " in the rear box makes perceptual knowledge further distil again, weldering one sagging iron nail on the moon figure movable axis on second moon rotating disk, because the gravity of iron nail, make hazy " moon " no matter go to which orientation, bright one side is always towards " sun ", the student fully understands the phases of the moon origin cause of formation from the continuous variation of " people's sight line " " moon " light and shade composition drawn between earth figure and the moon figure from height of rational.

Compared with prior art, visual in image, the vivid and interesting of the utility model demonstration effect helps to motivate students' interest in learning, and the learning initiative of mobilizing students has very big practical reference value.
