Embodiment Construction

[0072] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0073] The present invention proposes a seismic omnidirectional vector electrostatic levitation geophone, which is equal and balanced in all directions in the spatial structure, which is a structural advantage that geophones in the prior art do not have, and can realize complete Electrostatic levitation. The specific structure of the seismic omnidirectional vector electrostatic levitation detector is introduced below.

Abstract

The present invention discloses a seismic omnidirectional vector electrostatic suspended detector which comprises a tetrahedron hollow structure, an inner layer hollow base and an outer layer hollow base. The inner layer hollow base and an outer layer hollow base are inside and outside the tetrahedron hollow structure with the same distance and have the same structure and different sizes. Each surface of the tetrahedron hollow structure has a solid part and a hollow part. The solid part is an isosceles triangle, and a quadrangle formed by the angular bisectors of two angles of each surface is connected to a pass surface center point. The hollow part is two triangles, and the centers of pass surfaces formed by the angular bisectors of two angles are connected. According to the seismic omnidirectional vector electrostatic suspended detector, a space full vector detection structure is designed, thus the novel seismic omnidirectional vector detector technology is realized, the attributes of the frequency, amplitude, phase, vibration direction and the like of a seismic wave field and especially the full information detection of the divergence and rotation of a wave power field can be completed.

Description

technical field [0001] The invention relates to the technical field of geophones, in particular to a seismic omnidirectional vector electrostatic levitation geophone. Background technique [0002] According to the wave theory, the wave information is not limited to the amplitude, frequency, and phase of the wave, but also includes the vibration properties and direction of the wave field, the divergence of the force field and the curl vector and other attributes of various types of space motion. These spatial motion properties contain rich information that is indispensable for wave research, and can play an important role in wave field separation, signal-to-noise ratio, fidelity, imaging accuracy, and medium property analysis. However, the existing seismic acquisition and detection technology can only detect information such as amplitude, frequency, and phase, and basically has no function of detecting the spatial motion properties of fluctuations. [0003] For this reason, ...
