Abstract

The invention discloses a micro-incline generation device for field proving of a clinometer, and relates to a geological instrument proving technique. The device consists of a base, support screw rods, cushion blocks, a direct-current motor, a driving gear, a driven gear, piezoelectric ceramic, a sensing unit and a touch sheet. The method comprises the following steps of: (1) coarsely tuning for the first time; (2) coarsely tuning for the second time; (3) finely tuning by utilizing the piezoelectric ceramic 70; (4) measuring micro displacement of the clinometer through a precision displacement measuring meter; and (5) calculating the angle variation of the clinometer by the micro displacement, and comparing the angle variation of the clinometer with the output voltage variation of the clinometer, thereby obtaining a scale value. The micro-incline generation device for field proving of the clinometer provided by the invention has a small volume, is convenient to carry, is convenient to operate, saves time, is compatible with proving, and is suitable for proving the clinometer.

Description

technical field [0001] The invention relates to a calibrating device for geoscience instruments, in particular to a micro-tilt generating device for field calibrating an inclinometer. Background technique [0002] The tiltmeter is an instrument used to observe the tilt of the earth, and is suitable for observing solid tides and slow earthquakes. [0003] At the end of the seventeenth century, when Newton discovered the law of universal gravitation and used it to explain tidal phenomena, people imagined that the tidal force of the sun and moon would cause the direction of the plumb line to change. At that time, many people tried to measure the change of the tidal force of the sun and the moon on the equilibrium position of the free-hanging plumb pendulum, and did a lot of experiments, but all failed due to insufficient measurement sensitivity. It was not until the German Hengler invented the horizontal pendulum in the 19th century, and the displacement was magnified many tim...
