Abstract
The utility model discloses a simple sun altitude measurer, which consists of a base (1) and a counter weight (2). The simple sun altitude measurer is characterized in that an arc panel (3) is fixed on the base (1) through a supporting rod, a semi-circular plate (4) is vertically fixed at the rear of the inner wall of the arc panel (3), angle display scales are arranged on a front plate surface of the semi-circular plate (4), a projection rod (5) perpendicular to the semi-circular plate (4) is fixed at a circle center of the semi-circular plate (4), and the counter weight (2) is tied on the projection rod (5) through a counter weight line (6). Compared with the existing sun altitude measurer, the simple sun altitude measurer measures sun altitudes by aid of projections of the projection rod on the arc panel without rotating the projection rod, can conveniently and accurately measure size of the sun altitude angles, is simple in structure, convenient in use, low in manufacturing cost and favorable for being popularized and applied in middle schools widely, and can be widely used for geography teaching.
Description
Technical field
The utility model relates to a kind of improvement of altitude of the sun measurement mechanism, specifically 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, the centre position on described back up pad surface is 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.
Summary of the invention
The purpose of this utility model is to provide a kind of making simple in structure, easy, easy to use, can measure the simple and easy altitude of the sun measuring instrument of sun altitude exactly.
For reaching above purpose, the technical scheme that the utility model adopted is: this simple and easy altitude of the sun measuring instrument, constitute by base and weight, it is characterized in that on the base by support bar fixing on cambered plate, first circular slab is vertically fixed at inwall rear portion at cambered plate, be provided with the angle indicating graduation on the front face of semicircular plate, the shadow bar vertical with semicircular plate on the circle centre position of semicircular plate is fixing hangs up weight by the weight linear system in shadow bar.
The utility model is also implemented by following measure: the madial wall of described cambered plate is provided with graticule; The bottom sidewall of described cambered plate is provided with through hole, and the weight line passes through hole system and hangs in the shadow bar.
The beneficial effects of the utility model are: compare with the altitude of the sun angle measuring instrument of present use, adopt shadow bar's projection on cambered plate to measure sun altitude, need not to rotate shadow bar, can measure the size of sun altitude easily and accurately; And simple in structure, easy to use, cost of manufacture is low, is beneficial in vast middle school and applies.Can be widely used in geographical teaching.
Description of drawings
Fig. 1, be structure front-view schematic diagram of the present utility model.
Fig. 2, be structure schematic top plan view of the present utility model.
Embodiment
Make the utility model with reference to accompanying drawing 1,2.This simple and easy altitude of the sun measuring instrument, constitute by base 1 and weight 2, it is characterized in that on the base 1 by support bar fixing on cambered plate 3, vertically fix first circular slab 4 at the inwall rear portion of cambered plate 3, on the front face of semicircular plate 4, be provided with the angle indicating graduation, the zero groove of the angle indicating graduation on the semicircular plate 4 is parallel with base 1, the shadow bar 5 vertical on the circle centre position of semicircular plate 4 is fixing with semicircular plate 4, in shadow bar 5, be to hang up weight 2 by weight line 6, when using the utility model, adjust the position of base 1, when 90 ° of scale marks of the angle indicating graduation on weight line 6 and the semicircular plate 3 are overlapped, expression base 1 is in horizontality, and rotating base 1 then, and by observing the position of weight 2, make base 1 be in horizontality all the time, the projection of shadow bar 5 is dropped on the cambered plate 3 just, and at this moment, the indicated scale of projection is sun altitude.
The madial wall of described cambered plate 3 is provided with graticule 7, when the end of shadow bar 5 is supported to graticule 7 positions, and can reading; The bottom sidewall of described cambered plate 3 is provided with through hole 8, and it is to hang in the shadow bar 5 that weight line 6 passes through hole 8, is convenient to reading.
Claims (2)
1. simple and easy altitude of the sun measuring instrument, constitute by base (1) and weight (2), it is characterized in that going up by the fixing cambered plate (3) of going up of support bar at base (1), vertically fix first circular slab (4) at the inwall rear portion of cambered plate (3), on the front face of semicircular plate (4), be provided with the angle indicating graduation, in the fixing upward shadow bar (5) vertical with semicircular plate (4) of the circle centre position of semicircular plate (4), going up by weight line (6) in shadow bar (5) is to hang up weight (2).
2. simple and easy altitude of the sun measuring instrument according to claim 1 is characterized in that the madial wall of described cambered plate (3) is provided with graticule (7); The bottom sidewall of described cambered plate (3) is provided with through hole (8), and it is to hang in the shadow bar (5) that weight line (6) passes through hole (8).
