Abstract
The utility model relates to a kind of seismoreceiver, specifically a kind of low distortion geophone spring sheet, comprises interior annulus and outer toroid, it is characterized in that: be provided with 3 inner ring process bar and 3 outer ring process bar between described two annulus; Described Internal and external cycle 6 process bar with the center of circle of spring leaf for basic point matrix distribution.Article 3, the line between inner ring process bar head and the tail, its angle is between any two 120 °; Article 3, the line between outer ring process bar head and the tail, its angle is between any two 208 °.This effect designed finally fully can meet the data acquisition needs that high resolving power is surveyed, and improves the fidelity that seismic data gathers.
Description
Technical field
The utility model relates to a kind of seismoreceiver, specifically a kind of low distortion geophone spring sheet.
Background technology
The spring leaf of the seismoreceiver before 2003, be made up of simple three process bar, the angle between three muscle is 120 degree, but not high to seismoreceiver accuracy requirement at that time, degree of distortion≤0.2%, alias >=200.
But along with the raising of surveying accuracy, each manufacturer also carries out different improvement, and spring leaf changed inner ring two process bar 180 degree each other into afterwards, three, outer ring process bar 120 degree each other, has improve DeGrain the technical indicator of wave detector.
Utility model content
The purpose of this utility model is the data acquisition needs for meeting high-resolution exploration, improves the fidelity that seismic data gathers, provides a kind of low distortion geophone spring sheet.Realize particular by following technical scheme:
A kind of low distortion geophone spring sheet, comprises interior annulus 3 and outer toroid 4, it is characterized in that: be provided with 3 inner ring process bar 1 and 3 outer ring process bar 2 between described two annulus; Described Internal and external cycle 6 process bar with the center of circle of spring leaf for basic point matrix distribution.
Further, in technique scheme, the line between described 3 inner ring process bar 1 head and the tail, its angle is between any two 120 °.
Further, in technique scheme, the line between described 3 outer ring process bar 2 head and the tail, its angle is between any two 208 °.
Further, in technique scheme, the length of described outer ring process bar 2 is 4/5-5/6 arc length.
Further, in technique scheme, described outer toroid 4 is provided with an outside projection, described interior annulus 3 is provided with an inside projection.
The effect of this design, finally in order to meet the data acquisition needs that high resolving power is surveyed, improves the fidelity that seismic data gathers.By length and the angle of adjustment spring leaf process bar, the technical indicator of seismoreceiver is made to have a raising, degree of distortion by original≤0.2% drop to≤0.1%, alias brings up to >=250Hz by original >=200Hz, and linear, stability when substantially increasing seismoreceiver work and life-span.
Accompanying drawing explanation
Fig. 1 is the utility model one-piece construction schematic diagram.
Fig. 2 is the utility model modified one-piece construction schematic diagram.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further details.
As shown in Figure 1, the utility model low distortion detector spring leaf is by beryllium bronze band according to pre-designed figure lines, and through rigorous, accurate chemical corrosion forms.Comprise interior annulus 3 and outer toroid 4, it is characterized in that: between described two annulus, be provided with 3 inner ring process bar 1 and 3 outer ring process bar 2; Described Internal and external cycle 6 process bar with the center of circle of spring leaf for basic point matrix distribution.
For improving serviceable life of wave detector and stability, design 3 inner ring process bar 1 from beginning to end between line, its angle is between any two 120 °.Article 3, the line between outer ring process bar 2 head and the tail, its angle is between any two 208 °, and, redesign the length of process bar, make its length reach the length of the circular arc 4/5-5/6 of outer ring process bar.
By length and the angle of adjustment spring leaf process bar, the technical indicator of seismoreceiver is made to have a raising, degree of distortion by original≤0.2% drop to≤0.1%, alias is brought up to >=250Hz. and linear, the stability substantially increased when seismoreceiver works and life-span by original >=200Hz.
