Abstract
The utility model relates to a multifunctional combined type sundial for teaching, which is substantially composed of a pointer for projecting sun shade, a sundial face for bearing projection of the pointer, scale marks on the sundial face, a spirit level type compass, an electronic clock and a solar activity simulation device. The multifunctional combined type sundial for teaching is simple and clear in structure, high in operability and convenient to use. Various sundials can be demonstrated in all weather during middle and primary school teaching process, manipulative abilities of students can be strengthened, and understanding on working principles of various sundials can be improved.
Description
Technical field
The utility model relates to a kind of instruments used for education that the timing purposes is arranged, and utilizes sun angle and point of vertical to come Measuring Time, can be used as the combined type corona that polytype uses.
Background technology
At present; The people is known various corona function singlenesses as instruments used for education at present; Corona, equatorial corona, rectilinear corona when common corona divides Horizon; Lack the link of starting mostly, be unfavorable for cultivating our students ' practical ability, be unfavorable for that we deepen the understanding to the principle of work of various coronas.Can't in the indoor short time, demonstrate whole day, annual sundial shadow service chart.
Summary of the invention
The utility model purpose is: a kind of multifunction combined corona that is used to impart knowledge to students that provides; Be for; Common altitude azimuth form corona, equatorial corona, rectilinear corona, solar term formula corona are gathered; Through changing sundial face, sundial pin, adjustment sundial face tilt angle realizes different functions, can be in indoor demonstration through sun orbit.Can also come acknowledging time, solar term through the shadow of observing the sundial pin in the sun and probe into sun shadow Changing Pattern in a day, measurement sun altitude etc.Thereby increase the comprehension of student, make the teacher convenient when lecturing various corona corona.
A kind of multifunction combined corona that is used for middle and primary schools' teaching of the utility model; Comprise solar simulation orbit, lampet, sundial face, sundial pin, removable bottom, clock and watch, level-meter type compass, subsolar point trajectory table, sundial face tilt angular metric hornwork; Place the base plate of sundial face (3) and sundial pin (4) and place between the base plate of clock and watch and be provided with whirligig, solar simulation tracks (1) and base plate connection whirligig, free to rotate; Porose in the middle of the sundial face (3); Sundial pin (4) passes and inserts on the base plate in the middle of sundial face (3), and sundial pin (4) bottom is a removable jew, is not fixed on the base plate.Being provided with on the solar simulation tracks (1) can movable in orbit lampet.The solar simulation orbit is installed on the removable bottom and can rotates freely; The lampet afterbody is installed on the solar simulation orbit with head, and the subsolar point trajectory table is mounted on the junction of solar simulation tracks and removable bottom, and removable bottom is made up of two base plates; Two base plates connect with head; Can freely overturn, sundial cushion is on the aperture on the removable bottom, and the aperture in the middle of the sundial face sees through the sundial pin and is positioned on the removable bottom; One side of removable bottom is equipped with a pointer and protractor (sundial face tilt tolerance hornwork), and protractor and pointer are installed on two parts of removable bottom respectively.
The utility model device is provided with the solar simulation orbit on base plate, and on analog orbit, is provided with the lampet that is similar to the sun.Such setting greatly facilitates teaching, makes the student not have to carry out activity under the situation of sunlight in the same old way, understands different regions and the time of time, has increased students understand ability and geographical knowledge.
The utility model device is provided with the cabinet face and the sundial pin of removable jew, and has attached blank sundial face.It is multi-functional that such setting has had this corona, and replaceable different sundial face and sundial pin cooperate removable bottom, have the function of dissimilar coronas.Such function has been saved spending greatly, and utilization rate is higher.Subsidiary blank sundial face is used for the student starts to make, and has strengthened students'ability for practice and comprehension.

Reference numeral:
1, solar simulation orbit 2, lampet 3, sundial face 4, sundial pin 5, removable bottom 6, clock and watch 7, level-meter type compass 8, subsolar point trajectory table 9, sundial face tilt angular metric hornwork,
Embodiment:
Below in conjunction with Figure of description the multifunction combined corona of the utility model is described further.
Like Fig. 1, shown in Figure 2; Multifunction combined corona; Comprise solar simulation orbit (1), lampet (2), sundial face (3), sundial pin (4), removable bottom (5), clock and watch (6), level-meter type compass (7), subsolar point trajectory table (8), sundial face tilt angular metric hornwork (9), said solar simulation orbit (1) is 180 ° of semicircles, and lampet (2) is placed on the track (1); Also can do 180 ° and slide simulated solar.Removable bottom (5) is gone up circular groove of compacting, and sundial face (3) is put in wherein, and sundial pin (4) is assigned on the aperture of removable bottom (5) through the aperture in the middle of the sundial face (3).
Clock (6) and level-meter type compass (7) are fixed on the removable bottom (5) with fixing glue or other modes in addition.
Adjust sun direct projection angle and sundial face tilt angle when the utility model uses, slip lampet (2) just can be understood the principle of corona.
This corona apparatus structure is simple, easy to use, can reduce the trouble of carrying a plurality of dissimilar coronas because of using different corona teaching to bring, and wherever when uses simultaneously, has further increased students'ability for practice.
Claims (2)
1. multifunction combined corona; Mainly comprise solar simulation orbit (1), lampet (2), sundial face (3), sundial pin (4), removable bottom (5), clock and watch (6), level-meter type compass (7), subsolar point trajectory table (8), sundial face tilt angular metric hornwork (9); It is characterized in that: place the base plate of sundial face (3) and sundial pin (4) and place between the base plate of clock and watch and be provided with whirligig, solar simulation tracks (1) and base plate connection whirligig, free to rotate; Porose in the middle of the sundial face (3); Sundial pin (4) passes and inserts on the base plate in the middle of sundial face (3), and sundial pin (4) bottom is a removable jew, is not fixed on the base plate.
2. multifunction combined corona according to claim 1, it is characterized in that being provided with on the said solar simulation tracks (1) can movable in orbit lampet.
