The lower end of the indicated needle is provided with a heavy bob; the values of slope corresponding to each angle are marked on the semi-circle scale; moreover, the base is a straight rule composed of a plurality of parts. The utility model has the advantages of simple operation, convenience for carrying, multiple functions and visual reading.

Description

Clinometer

The utility model is a kind of gradiometer, relates to a kind of device of measuring value of slope.

Usually, mostly people are to wait with ruler, spirit-leveling instrument and finish when measuring the gradient, and the data that this method obtains must just can obtain value of slope through calculating, and data-generating process complexity.And Patent Office of the People's Republic of China provides a kind of measurement of dip angle device simple in structure in the application number of on Dec 12nd, 1987 bulletin for 86209249 patented claim, obtain the gradient, still need calculate or table look-up.And it utilizes bubble to indicate the angle of being surveyed, and often makes the precision of measurement lower.In addition, carry out in the process of slope measuring, will measure the length of some region etc. sometimes, thereby need carry more instrument, bring inconvenience to the gauger.

The purpose of this utility model is, designs a kind of novel gradiometer, enables directly to obtain value of slope by measuring, and has the function of measuring length, angle concurrently, and be easy to carry.

The utility model is to realize like this.It is that the pointer of axle is formed by the semicircle chi that has scale on base, the base with the semicircle chi center of circle, and the lower end of pointer has a weight.One air level is arranged on the base.Base is the ruler that has the length scale, and it is formed by folding two sections at least.Base can be by at least three sections hinged forming, and its at least one end has magnet, are embedded with iron block on the side of the base that the folding back of ruler magnet can touch.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a stereographic map of the present utility model;

Fig. 2 is the front elevation of the utility model semicircle chi;

Fig. 3, Fig. 4 are practical constitutional diagrams of the present utility model;

Wherein, 1-base, 2-air level, 3-semicircle chi, 4-pointer, 5-weight, 6,7,8-iron block, 9,10-magnet.

The utility model is by base (1), spirit-leveling instrument (2), and semicircle chi (3), pointer (4), weight (5) are formed.Base (1) is a ruler, indicates the length scale above, and its upper surface is parallel with lower surface.Base (1) is formed by folding two sections at least, can adopt articulated manner between each section.The two ends of base (1) are equipped with on the relevant position of locking device after each section ruler is amounted to fit structure, makes base (1) amount to the back state and fixes.As, can magnet be installed at the two ends of base (1), and on corresponding position, iron block is installed, make base (1) thus in the shape of folded position lower magnet and iron block adhesive firm banking (1), be positioned at the magnet (9) at base (1) two ends, the end face of (10) and the upper and lower Surface Vertical of base (1).When base (1) had three sections hinged forming at least, base (1) side that ruler folding back magnet (9) can touch was embedded with iron block (6), (7), (8) on the allocation really.On iron block (6), (7) the magnet locating slot is arranged.Several sections rulers cooperate, and can make magnet (9) and iron block (6), (7) adhesive and by the magnet locating slot relative position of several sections rulers be fixed, and are formed with the triangle of certain angle, so that measure some angle.As to make first section ruler length be 20.71cm, second section ruler is 29.29cm, when length is iron block (7) adhesive of 40.01cm on magnet (9) and the 3rd section ruler, formed leg-of-mutton interior angle is respectively 30 °, 43 ° and 105 °, this contains in the construction commonly used at foot bridge, when length is iron block (6) adhesive of 20.71cm on magnet (9) and the 3rd section ruler, first section ruler is vertical with the 3rd section ruler, formed triangle is a right angled isosceles triangle, this is drawing vertical line, commonly used when curve ranging or unwrapping wire, be positioned at the magnet (10) and iron block (8) adhesive of base (1) other end, form stable structure.Also can really the outside be installed by the iron block of iron chi instead of separate at ruler, the scale groove of iron chi is as the magnet locating slot.For in magnet (9), (10) and demagnetization as early as possible after iron block or iron chi separate, iron block (6), (7), (8) or the most handy soft iron of iron chi are made.Air level (2) and semicircle chi (3) are installed on the upper surface of base (1).The face of semicircle chi (3) is marked with scale and corresponding value of slope.Pointer (4) is connected on the semicircle chi (3) by the axle of the circle centre position of semicircle chi (3), and there is a weight (5) lower end of pointer (4), and it keeps pointer (4) all the time perpendicular to the surface level points upwards.When measuring the slope, the scale value that pointer (4) points to is the value of slope on institute deviational survey slope, i.e. pointer (4) and tangent value perpendicular to the angle α of the line of symmetry of the semicircle chi (3) of base (1), and the α pitch angle on institute deviational survey slope just.Scale value can mark by following rule:

α value scale value value of slope

45 ° of 1 1:1 when α≤45 °

33°41′ 1.5 1：1.5

26°34′ 2 1：2

21°48′ 2.5 1：2.5

18°26′ 3 1：3

11°18′ 5 1：5

5°42′ 10 1：10

56 ° of 18 ' 1.5 1.5:1 when α＞45 °

63°26′ 2 2：1

71°34′ 3 3：1

75°57′ 4 4：1

78°41′ 5 5：1

84°17′ 10 10：1

It is 0 that semicircle chi (3) is gone up the pairing value of slope of its line of symmetry.In addition, the face of semicircle chi (3) can also mark the scale and the value thereof of expression angle.As mark the value at α angle.Like this, in the value of measuring the gradient, can record the value at the pitch angle on slope.Mark the value of the line and base (1) angle in each scale and the center of circle, then the utility model can be used as general protractor use again.

The utility model function is many, and is simple to operate, and reading is comparatively directly perceived, and has characteristics easy to carry.
