Description
Technical Field
The utility model relates to the field of gravity testing, in particular to an auxiliary device for determining the altitude of a gravity meter.
Background
A gravity meter is a measuring instrument that determines the acceleration of gravity.
In the process of measuring the gravitational acceleration, two data need to be measured; one is the data measured by the gravity meter itself; secondly, the altitude of the gravity meter; the acceleration of the high school overweight has direct influence on the altitude, so that the accurate value for measuring the altitude of the gravity meter is particularly important.
The current process of measuring gravitational acceleration is:
firstly, after a tripod (special for a gravity meter) is compacted and leveled on the ground, the gravity meter is placed on the tripod for measurement.
Secondly, the RTK is installed at the upper end of a centering rod (with a size scale) of the gravity gauge (the height of the altitude is measured by using the RTK and the centering rod at present), the lower end of the centering rod falls on the ground, and the centering rod is manually held; the altitude of the detection place is obtained by subtracting the altitude of the centering rod from the altitude measured by the RTK.
However, some measurement sites are soft in soil, and the centering rod can go deep into the ground, thereby causing an error in altitude. (defect one)
In addition, the altitude is measured by adopting a star station searching and separating mode, and the RTK needs to have enough time for measuring the altitude, so that a centering rod needs to be manually held for a long time; the process consumes the physical strength of the staff and increases the fatigue of the staff. (Defect two)

Further, three adjusting bolts are uniformly arranged in the radial direction of the support pipe and are in threaded connection with the wall of the support pipe; thereby ensuring that the centering rod remains vertical.
