Background technique

In the process of geological exploration or geotechnical engineering investigation, it is sometimes necessary to measure the slope angle of the slope. At present, the slope angle measurement of the slope is mainly carried out by using the geological compass.

Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present utility model.

Embodiments of the present utility model:

A simple measuring device for slope inclination, as shown in accompanying drawings 1-4, comprises a bottom plate 1, a turning plate 3 is connected above the center line of the bottom plate 1 via a rotating shaft 2, and the width of the turning plate 3 is 1/2 of the width of the bottom plate 1 The side of the bottom plate 1 at one end of the rotating shaft 2 is provided with an upright semicircular ruler 4, the axis of the semicircular ruler 4 is coaxial with the rotating shaft 2, and the side of the semicircular ruler 4 close to the turning plate 3 is provided with an angle scale 5.

Working principle: When in use, the same as the preparation for the measurement of the geological compass, two points of equal height are respectively set at the upper and lower positions of the measurement slope, such as a column, the top of a human head, etc.; then the utility model is placed at the lower end of the contour point. , adjust the bottom plate 1 to the level and fix it, then the human eye is close to the edge of the bottom plate 1, and the flip plate 3 is turned over until the eye can just see the contour point at the upper end from the edge of the bottom plate 1 against the upper edge of the flip plate 3, At this time, keep the position of the flip plate 3 unchanged, and read the inclination of the flip plate 3 through the angle scale 5. Since the width of the flip plate 3 is half of the width of the bottom plate 1, the flip plate 3 is just connected to the center line of the bottom plate 1, so people The triangle formed by the line of sight and the side of the bottom plate 1 and the flip plate 3 is an isosceles triangle. Divide the angle of the inclination of the flip plate 3 by 2, which is the inclination angle of the human eye line, that is, the angle of the slope.

Preferably, an observation slot 6 is provided on the side of the bottom plate 1 away from the rotating shaft 2 , and an aiming slot 7 is provided on the side of the flip plate 3 away from the rotating shaft 2 , and the observation slot 6 and the aiming slot 7 are located on the same longitudinal plane perpendicular to the rotating shaft 2 On; the line connecting the observation slot 6, the aiming slot 7 and the point of the rotating shaft 2 on the longitudinal plane is an isosceles triangle. During measurement, the human eye starts from the observation slot 6 and looks at the target through the aiming slot 7. Since the positions of the observation slot 6 and the aiming slot 7 are pre-set so that they are located in the same longitudinal plane, the eyes are not easily shifted during observation. , the isosceles triangle formed with the sides of the bottom plate 1 and the flip plate 3 is more standard, and the measurement results are more accurate.
