Abstract
Butt-welding two ends of glass tube make a glass circular ring. Transparent liquid ether is filled to the said glass circular ring and a bubble in diameter 4mm is formed in the ring. Scale is marked on external side of the glass circular ring. Using buoyant force of ether makes tangency between the bubble and scale line so as to obtain angle of inclination or angle of slope measured.
Description
Technical field
The present invention relates in the field geological work with the measurement of geologic compass the formation dip and the hillside angle of gradient.
Background technology
At present, the used geologic compass (DQY-1 type geologic compass) of geologist mainly relies on the adjusting plate level when measuring the inclination angle or the angle of gradient, makes bubble reading then between two parties.Its shortcoming is, because manual adjustments, bubble is difficult for placed in the middle, and is difficult to guarantee that bubble is strict placed in the middle, and promptly reading error is bigger.
Summary of the invention
Be difficult for placed in the middle and the very difficult strict problem placed in the middle of bubble for solving bubble, the present invention proposes a kind of improvement design proposal, can overcome above problem simultaneously.
Technical scheme of the present invention is: with one section glass tube two ends butt joint, make a glass annulus, in glass ring, fill transparency liquid with---the bubble of a hexyl ether and a diameter 4mm, calibrate on the semi-circumference of the glass ring outside 180 degree, meter full scale is 90 degree---0 degree---, and 90 spend, the scale minimum value is 1 degree, the glass annulus is fixed by snap ring on the index dial in the compass and cover glass, and one of them 90 degree groove groove used with regulating magnetic declination alignd.
The invention has the beneficial effects as follows.In the geological work formation dip, the hillside angle of gradient are measured fast and accurately in the open air.
Description of drawings
The invention will be further described (part identical with DQY-1 type geologic compass all do not drawn among the figure) below in conjunction with accompanying drawing.
Fig. 1 is the designed glass circular planes figure of the present invention, and the planimetric map internal digital is that the amplification of glass annulus surface number shows.

Fig. 3 is the sectional elevation of Fig. 2.
Fig. 4 is the floor map of Fig. 3.
Fig. 5 is the floor map of glass annulus measuring method.
1. snap ring of fixing, 2. glass annulus among the figure.
Embodiment
In Fig. 2, glass annulus (2) is fixed by the fixing snap ring (1) and the cover glass (not shown) on top.
The measuring method of the inclination angle or the angle of gradient: after measuring the rock stratum tendency, compass turned over turn 90 degrees, utilize the interior hexyl ether of glass tube that the buoyancy (bubble rests on the vertical the top of annulus all the time) of bubble is got final product direct reading, and do not need with compass, to regulate plate level as existing.Can get the tangent line reading x of bubble and scale mark during reading, suppose that the corresponding scale value of bubble diameter is 4 lattice, then inclination angle or angle of gradient α=x ± 4/2=(x ± 2) °, be that reading x is when being the smaller value of bubble and scale mark tangent line, α=x+4/2=(x+2) on the contrary °, α=x-4/2=(x-2) °.
Claims (3)
1. the geologic compass of an improved comprises shell, needle, circular bubble, index dial and glass annulus, it is characterized in that, at the glass annulus of now being fixed by fixedly snap ring and cover glass with one of design in the geologic compass.
2. a geologic compass as claimed in claim 1 is characterized in that, with the butt joint of glass tube two ends, makes the glass annulus.
3. a geologic compass as claimed in claim 1 is characterized in that, fills hexyl ether and a bubble in glass ring with, engraves scale in the glass ring outside.
