Sensitive probe and precise vertical spring portable type gravity meter

Abstract

The invention discloses a sensitive probe and a precise vertical spring portable type gravity meter. The sensitive probe at least comprises a swing body and an insulating electrode frame. The electrode frame comprises a bottom opening, an erect cylinder, an insulating frame body and an insulating plate. The shape of the insulating plate is identical with the shape of the top of the frame body. The shape of the swing body is identical with that of the frame body. Even number pairs of electrode plates are plated on the lateral wall of the frame body. At least one pair of electrode plates are plated on the top wall of the frame body and the insulating plate. The swing body is located between the top wall of the frame body and the insulating plate. The distances from the swing body to all the electrode plates are equal. The gravity meter uses the sensitive probe and is a high-precision vertical-swing clinometer, relative gravity acceleration and two-dimensional crustal inclination signal measuring are achieved at one step, and double functions of an existing high-precision gravity meter and an clinometer are achieved.

Description

technical field [0001] The invention relates to the technical field of gravitational acceleration measuring instruments, in particular to a portable gravimeter with a sensitive probe and a precise vertical spring. Skew data for areas of research in demand. Background technique [0002] Acceleration of gravity is a basic geophysical constant, and accurate measurement of acceleration of gravity is of great significance in the fields of earth science and resource exploration. [0003] Gravitational acceleration measurement can be divided into absolute measurement and relative measurement, and the corresponding instruments are called absolute gravimeter and relative gravimeter respectively. Absolute gravimeter refers to the measurement of the absolute size of the acceleration of gravity g, and the commonly used methods include the pendulum method and the falling method. The relative gravimeter refers to the measurement of the relative change of the acceleration of gravity g, w...

Problems solved by technology

Gravitational tides and tilted tides have always been important topics in geophysical research, and there have been inventions focusing on the integration of two geodetic instruments into one measurement system (Li Jiaming, et al. Gravity and tilted solid tide integrated observer, CN201110895Y, 2008) , but the system is essentially just a measurement combination of a gravimeter and an inclinometer with independent functions
