Abstract
A visualized balance level belongs to the field of the improvement on the balance level. Two ends of a section of glass pipe are butted to form a glass circular ring; the glass circular ring is internally filled with transparent colored liquid taking a half capacity of the glass circular ring; and the outmost circle of the glass circular ring is marked with tag lines. A flat plate is arranged on the balance level and can be combined with the balance level. The visualized balance level is mainly used for visually knowing the inclination condition of surveying and mapping instruments at any time.
Description
Affiliated technical field
Before measuring, want survey field leveling to guarantee that instrument is that the measurement of level is only surveying instrument accurately, the inclination situation of the intuitive judgment instrument of usefulness vision.
Background technology
At present, the level-off that needs that the mapping operations person is used just can be measured surveying instrument accurately, its shortcoming is, and because existing instrument is the substep level-off, just the observer of this is from visually knowing its level whether on earth, but it is level that the observer can not know instrument integral body, also will carry out next step, up to all finish in steps and can guarantee that just instrument integral body is level of approximation.Behind the level-off, the observer also needs instrument is proceeded operation, and instrument is a level when often just having begun, but in observer's the observation process, in the time of with conversion position, instrument has begun to tilt, and the gauger does not often very clearly recognize this point.Influenced by gauger's experience, level of skill and attitude very big for measurement result like this, increased measuring error.
Summary of the invention
Can not represent whether level of instrument integral body intuitively in order to overcome existing instrument of surveying and mapping, the present invention can intuitively, clearly represent the horizontal situation of instrument integral body.
The technical solution adopted for the present invention to solve the technical problems is: with one section glass tube two ends butt joint, make a glass annulus, now glass ring is lain on the surface level, its projection at surface level is a positive annulus, with the circle of annulus outmost turns vertically upwards translation obtain an imaginary face of cylinder, the intersection of this face of cylinder and glass tube (outmost turns of glass annulus just) is coated mark line (labeling method of mark line can adopt the method at reference mark line on glass).Account for half transparent colored liquid (as cresols) of glass annulus volume with filling with in the glass annulus.
Glass ring is judged inclination situation the principles of science than the more accurate institute of circular bubble foundation:
The radius of glass ring is R
1, the radius of circular bubble bubble is R
2, suppose both identical angle [alpha] that tilted, then both distances of departing from the scale mark of indication level are respectively R
1α and R
2α is because R
1Greater than R
2So when the angle that glass ring and circular bubble tilt identical, it is farther that glass tube departs from the scale mark of indication level.
The invention has the beneficial effects as follows that people can be clear by the relation between liquid level and the mark line in the sight glass pipe, whether get information about the present level of instrument of surveying and mapping.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the designed glass circular planes figure of the present invention.
Fig. 2 adapts to spirit-leveling instrument view of the present invention.
Fig. 3 be the present invention according to the big circular portion synoptic diagram in the principle.
Fig. 4 be the present invention according to the roundlet part synoptic diagram in the principle.
Fig. 5 is the forward view of glass annulus.
1. mark lines among the figure, the 2. circle of glass annulus outmost turns.3. the flat board on the spirit-leveling instrument
Embodiment
With the spirit-leveling instrument is how example explanation the present invention combines with instrument of surveying and mapping, (its concrete technology belongs to prior art to three rotary flat boards of peace on the pedestal of spirit-leveling instrument, do not do and specify), these three flat boards just can not continue to rotate when forwarding surface level (three flat boards are positioned at sustained height when forwarding surface level to) to, during use with the glass annulus among the present invention by the following spirit-leveling instrument that puts, put down three flat boards then, above glass ring is placed on.
Judge whether the direct-vision method of level: liquid level in the glass tube and the angle between the mark line, if overlap with mark line, then level is if do not overlapped angle, then out-of-level.
Claims (1)
1. visual spirit-leveling instrument comprises that the butt joint of glass tube two ends makes a glass annulus, it is characterized in that outmost turns is coated to have filled volume in the glass annulus of mark line with and account for half transparent colored liquid of glass annulus volume.
