Patent attributes
The invention relates to a geoscientific observation technology, especially relates to a ground surface tiltmeter by using microscope for micro measuring. In order to solve the problems such as low reading accuracy and enormous error of the traditional ground surface tiltmeter, the invention provides a ground surface tiltmeter by using microscope for micro measuring, comprising a main body of the ground surface tiltmeter and a micro-measuring device, the main body of the ground surface tiltmeter is a vertical pendulum ground surface tiltmeter or a horizontal pendulum ground surface tiltmeter, the micro measuring device comprises an optical microscope, the focus of objective lens of said microscope is coincident to the reading point of the ground surface tiltmeter. The invention adopts optical microscope to amplify the ground gradient of the ground surface tiltmeter, ensures high measuring accuracy of the ground surface tiltmeter, and also makes the assembly simple, and the production cost reduced.
