Abstract
An earth function displayer in Chinese style contains a ball shell with anti-magnetized ball surface pictures, easy ot be attracted by magnetic models. A rotating shalf passes through the north and south poles at the ball center fixed on the hand corner of a cylinder at the center of the baseseat and controlled by super-slow speed motors and internal motive force transmission device. Asolar light direct irradiaation points device and a moon displayer are separately rotating connected on a circular shunting track at the upper end of the column hand by a jib arm which can show to the students in images the earth scientifie knowledge on geographical classes.
Description
The present invention relates to a kind of Chinese style earth function demonstration instrument.
Existing domestic and international terrestrial globe, general all is to be made of the single earth model spheroid that stands in the rotating shaft, earth multidimensional dynamic process is not described, the mutual relationship of not showing the earth and the sun can not be showed revolution, rotation displacement function that earth orientation is tilted, thereby the geoscience knowledge in the geographical teaching of making over is difficult to the student that shows of imagery, cause air-to-air religion, complete by memorize mechanicalling of student, neither sturdy also usually has misunderstanding.
The purpose of this invention is to provide a kind of Chinese style earth function demonstration instrument, but the displaying of its imagery scientific knowledge relevant with the earth is beneficial to geographical imagery teaching.
For achieving the above object, the present invention takes following design proposal: this Chinese style earth function demonstration instrument comprises that diamagneticization that has the sphere picture helps the spherical shell of magnetic model absorption, be installed with a spheroid turning axle between this north and south, spherical shell center limit, turning axle is fixed on the hollow curve of arc of base center stand column handle, the operation of this rotating shaft is controlled by super motor and internally-powered transmitting device at a slow speed, and a sunshine point of vertical cell arrangement and a moon display unit device are fixed in prolonging of rotating shaft by cantilever respectively and in the circular transition.
For showing the terrestrial attraction function of the earth, the various micro magnetic models of absorption are arranged on spherical shell.
For popularizing earth ' s interior structure knowledge, the observation fenestra of showing earth ' s interior structure is arranged on spherical shell, can show the hierarchy of earth ' s interior structure.
The invention will be further described below in conjunction with accompanying drawing
Fig. 1 is a structural representation of the present invention
Fig. 2 is spring, summer, autumn, winter and solar light irradiation annotation four sides key diagram thereof
Fig. 3 shows card figure for intermediary's reference system
As shown in Figure 1, Chinese style earth function demonstration instrument of the present invention comprises that one has the diamagneticization spherical shell 4 of sphere picture, be installed with a spheroid turning axle 2 between this north and south, spherical shell center limit, turning axle is fixed on the curve 8 of base 13 center stand column handles 10, and another head end is pinned by ball cap.The operation of this rotating shaft is controlled by super motor and internally-powered transmitting device at a slow speed.Described base 13 support bars also comprise a column handle 10, one is placed in column handle upper end and omits the circle transition 9 of suitably prolonging, the curve 8 of support bar connects with rotating shaft 9 head ends, and a sunshine point of vertical cell arrangement 6 and a moon display unit device 7 are transferred in the circle transition by cantilever 601,701 respectively.
For showing the terrestrial attraction function of the earth, the spherical shell that has the sphere picture is diamagneticization and the spherical shell that helps the absorption of micro magnetic model, adsorbable magnetic model 3 is arranged on the spherical shell surface, this magnetic model 3 can be simulated ethnic group, animal, plant, the vehicles, weapons, typical buildings etc., thereby the terrestrial attraction function of comprehensively showing the earth, can show people to a colourful miniature earth surface, and induce teen-age spatial thought visionary and creativity.
For popularizing earth ' s interior structure knowledge, the observation fenestra 5 of showing earth ' s interior structure is arranged on spherical shell, can show the hierarchy of earth ' s interior structure.
Described super motor at a slow speed and internally-powered transmitting device can be guaranteed the earth reproduction of rotation function from West to East, and after guaranteeing to connect electricity (pressing power switch 14), the various micro magnetic models on the spheroid also can rotate thereupon.This transmitting device be embodied as prior art, repeat no more herein.
Described curve 8 is the arc hollow-core construction, and ball model inclined orientation location, ground had both been guaranteed in the design of its radian, guaranteed the internally-powered transmission again.
Column handle 10 is made with square tube, to establish spring, summer, autumn, winter and solar light irradiation annotation thereof at its peripheric surface diagram layer (as shown in Figure 2) is described on four sides.
The analogue body that described sunshine point of vertical cell arrangement 6 is a sun (being the preposition luminophor of arc body of representing the sun one in the present embodiment), and be equipped with intermediary's reference system display panel 11 at the base platform face.The content of this intermediary's reference system display panel is referring to Fig. 3, it is divided into 12 independently display units, is that collection " a year 12 months, a year generally have 24 solar term, Chinese see that in China the big or small visual impression of the sun became with the moon " three elements design into one.Can cooperate the work of this device, show the locomotive function of track on earth sphere of the sun, show the relation between the earth and the sun.
The setting of moon exhibiting device makes that astronomic knowledges such as total eclipse of the moon, partial lunar eclipse, total solar eclipse, partial solar eclipse, annular eclipse can object teaching.
Chinese style earth function demonstration instrument device of the present invention can carry out ocular demonstration, as move back and forth this device, both can understand---the north and south tropic, north and south polar circle, near area, two season of winter in summer equator how are not the hottest, the area is how the hottest near the spring and autumn equator, daytime half a year of north and south polar circle and night half a year are how antithesis, the summer of China, how the time on daytime was grown and weak point the time in the evening, and why China makes a clear distinction between the four seasons, the divisions of five bands ...The geographical teacher of religion needs only above-mentioned sunshine point of vertical apparatus for demonstrating is used as the sun, and rotates to the corresponding month on the corresponding display panel, opens spheroid and rotates power supply, just can say the climatic characteristic of the countries in the world of this month clearly.
The invention has the advantages that: because this device not only only has single geoid, it is straight also to be furnished with sunshine Exit point cell arrangement, moon display unit device, simulation people, the magnetic model of thing and supporting transmission system device, Can be with the student that shows of the geoscience knowledge image in the geographical teaching, what the student listened understands and easy reason Separate, remember firmly accurately.
