Abstract
The utility model relates to a simple solar-altitude measuring instrument which comprises a base (7), a supporting rod (5), a gravity weight line and a gravity weight (4), wherein a protractor plate (2) is connected with and arranged on the supporting rod (5) by an arc-shaped frame (3); the gravity weight (4) and the gravity weight line are connected with and arranged on the protractor plate (2) by a vertical rotating shaft (1); and the supporting rod (5) is connected with and arranged on the base (7) by a horizontal rotating shaft (6). The arc-shaped frame (3) and the protractor plate (2) are thin plates. The base (7) and the supporting rod (5) are cylinders. The simple solar-altitude measuring instrument can be easily and conveniently adjusted and operated and can better demonstrate and measure the solar altitude angle so as to compute the solar altitude as well as has the advantages that the overall consumed material is less, the cost is saved, the solar-altitude measuring instrument can be carried and put down gently and is favorable for the use in classroom demonstration.
Description
Technical field
The utility model relates to a kind of technical field of geography teaching in middle school teaching aid, is specifically related to a kind of simple and easy altitude of the sun measuring instrument.
Background technology
In geography teaching in middle school, sun altitude is an emphasis, is again difficult point, and the explanation of drawing on blackboard simply is too abstract, is difficult to allow the student understand.Sun altitude is meant the angle of sunray and earth surface.Someone has proposed a kind of altitude of the sun angle measuring instrument, comprise back up pad and base, back up pad is fixed on the base, described back up pad surface the centre position be provided with vertical groove, described back up pad is provided with panel board, described panel board is provided with scale value, described panel board is provided with pointer, described pointer two ends are provided with the vertical part perpendicular to pointer, the vertical portion at described pointer two ends is arranged with light hole, the center of circle of described two light holes is positioned on the same axis, and the two ends of described pointer are respectively equipped with the reading hole, is rotationally connected between described pointer and panel board and the back up pad.This altitude of the sun angle measuring instrument, though can measure the size of sun altitude, complex structure, the manufacturing cost height is unfavorable for penetration and promotion in vast middle school, and also needs rotating pointer when using, and uses inconveniently, measures not accurate enough.
The utility model content
The purpose of this utility model is at deficiencies such as existing simple and easy altitude of the sun measuring instrument cost height, complicated operation, demonstration effect out of true, provides that a kind of cost is low, easy and simple to handle, demonstration effect accurate simple and easy altitude of the sun measuring instrument.
The purpose of this utility model realizes by following technological means: a kind of simple and easy altitude of the sun measuring instrument, include base, pole, weight line, weight, be connected with the protractor plate on the described pole, described protractor plate is set on the pole by the connection of arc frame; Described weight, weight line are set on the protractor plate by the connection of vertical transfer axle; Described pole is set on the base by the axle connection of flatting turn.
Described arc frame, protractor plate are set to thin plate.
Described base, pole are set to right cylinder.
Compared with prior art the utlity model has following tangible advantage: the adjustment operation that Ben Jianyi altitude of the sun measuring instrument can be easily easy, demonstrate and measure the elevation angle of the sun preferably, thereby calculate altitude of the sun; The whole materials of this simple and easy altitude of the sun measuring instrument are less, save cost, gently remove and put down gently, are beneficial to class demonstration and use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-vertical transfer axle, 2-protractor plate, 3-arc frame, 4-weight, 5-pole, the 6-axle of flatting turn, 7-base.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
A kind of simple and easy altitude of the sun measuring instrument as shown in Figure 1 includes base 7, pole 5, weight line, weight 4, is connected with protractor plate 2 on the described pole 5, and described protractor plate 2 is set on the pole 5 by 3 connections of arc frame; Described weight 4, weight line are set on the protractor plate 2 by 1 connection of vertical transfer axle; Described pole 5 is set on the base 7 by axle 6 connections of flatting turn.Be provided with like this, this simple and easy altitude of the sun measuring instrument is when concrete the use, come the position of adjustment amount hornwork plate 2 by rotating vertical rotating shaft 1, when 90 ° of scale marks of the angle indicating graduation on weight line and the protractor plate 2 were overlapped, expression base 7 was in horizontality, rotate the axle 6 of flatting turn then and adjust base 1, and, make base 7 be in horizontality all the time by observing the position of weight 4, the projection of weight line is dropped on the protractor plate 2 just, at this moment, the indicated scale of projection is sun altitude.And then by calculating the altitude of the sun value; The whole materials of this simple and easy altitude of the sun measuring instrument are less, save cost, gently remove and put down gently, are beneficial to class demonstration and use.
Described arc frame 3, protractor plate 2 are set to thin plate.Be provided with like this, the utility model global design is lighter and handier, easy, can adjust operation easily, demonstrates and measure the elevation angle of the sun preferably.
Described base 7, pole 5 are set to right cylinder.Be provided with like this, further save materials of the present utility model and strengthen the dirigibility that the utility model is operated.
In a word, the utility model provides that a kind of cost is low, easy and simple to handle, demonstration effect accurate simple and easy altitude of the sun measuring instrument.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
