Abstract

The invention provides a spring relative gravimeter, and the gravimeter is used for measuring relative gravity. The gravimeter comprises a spring (1), a spring support (10), a spring adjustment rotary knob (4), a counter weight (2), upper and lower pole plates (3), a pole plate adjustment rotary knob (5), an upper and lower pole plate support (7), an upper and lower pole plate supporting seat (8), an upper and lower pole plate support adjustment rotary knob (6), and a gravimeter pedestal (9). The spring structure of the gravimeter enables a spring to deform and rotate around the center of the spring, greatly reduces the spatial scale of spring deformation, and can achieve the stretching of 20cm and even more in a very small space. In addition, the rigid sheet-shaped structure of the spring enables the gravimeter to be better in rigidity in other directions, and facilitates the embedding and protection of the spring.

Description

technical field [0001] The invention belongs to a mechanical mechanical structure and an electronic measurement system, in particular to a clockwork spring relative gravity meter. Background technique [0002] In geophysics and geodesy, it is often necessary to measure the relative change of the acceleration of gravity, and this type of instrument is called a relative gravimeter. High-precision relative gravimeters generally use zero-length springs or vertical springs. Whether it is a zero-length spring or a vertical spring gravimeter, the basic principle is that the spring deforms elastically under the action of a heavy hammer, and the change of the acceleration of gravity is measured through the elastic deformation of the spring. In order to meet the needs of high-precision measurement (the measurement sensitivity of the high-precision relative gravimeter can reach 0.002mGal or even higher), the sensitivity of the spring is extremely high, and it can feel extremely small ...
