Abstract
The utility model discloses a small -size ultralow frequency geophone spring leaf, specific theory relates to a geophone. The utility model discloses an interior ring and outer ring, be provided with 3 inner circle technology muscle and 3 outer lane technology muscle between two rings, 6 the technology muscle in interior outer lane use the centre of a circle of spring leaf to distribute its characterized in that as the basic point matrix: 3 line between the strip inner circle technology muscle head and the tail, its contained angle between two liang is 120, 3 line between the technology muscle head and the tail of strip outer lane, its contained angle between two liang is 216 - 223. The utility model discloses a length and the angle of adjusting spring piece technology muscle have improved linearity, the stability of geophone during operation greatly when satisfying geophone's technical indicator.
Description
Technical field
The utility model relates to a kind of seismoreceiver, specifically a kind of small-sized ultralow frequency 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
Technical problem to be solved in the utility model is to provide a kind of data acquisition needs that can meet high-resolution exploration, reduce the free-running frequency of wave detector, effective pickup seismic prospecting deep layer low frequency effective information, improves the small-sized ultralow frequency geophone spring sheet of the fidelity that seismic data gathers.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of small-sized ultralow frequency geophone spring sheet, comprises interior annulus and outer toroid, is 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, is characterized in that for basic point matrix distribution with the center of circle of spring leaf: the line between described 3 inner ring process bar head and the tail, and its angle is between any two 120 °; Line between described 3 outer ring process bar head and the tail, its angle is between any two 216 °-223 °.
Further technical scheme is, the length of described process bar is 37.785mm-39.275mm.
Further technical scheme is also, the line between described 3 outer ring process bar head and the tail, and its angle is between any two 220 °
The beneficial effect adopting technique scheme to produce is: the utility model, by adjusting length and the angle of spring leaf process bar, substantially increases linear, stability during seismoreceiver work while meeting the technical indicator of seismoreceiver.
Meet the data acquisition needs that high resolving power is surveyed in addition, reduce the free-running frequency of seismoreceiver, effectively pickup seismic prospecting deep layer low frequency effective information, improves the fidelity that seismic data gathers.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1-2 is structural representation of the present utility model;
Wherein: 1, outer toroid; 2, outer ring process bar; 3, inner ring process bar; 4, interior annulus.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in the figure, the utility model comprises interior annulus and outer toroid, is 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, is characterized in that for basic point matrix distribution with the center of circle of spring leaf: the line between described 3 inner ring process bar head and the tail, and its angle is between any two 120 °; Line between described 3 outer ring process bar head and the tail, its angle is between any two 216 °-223 °.
Preferably, the length of described process bar is 37.785mm-39.275mm.
Preferably, the line between described 3 outer ring process bar head and the tail, its angle is between any two 220 °.
The utility model is by beryllium bronze band according to pre-designed figure lines, and through rigorous, accurate chemical corrosion forms.For improving serviceable life and the stability of wave detector, spring leaf is designed to inside and outside six process bar, design inner ring three process bar 120 degree each other, and is 220 degree by the angular setting of outer three muscle, redesigns the length of process bar.Finally meet the data acquisition needs that high resolving power is surveyed, reduce the free-running frequency of seismoreceiver, effectively pickup seismic prospecting deep layer low frequency effective information, improves the fidelity that seismic data gathers.
By length and the angle of adjustment spring leaf process bar, while meeting the technical indicator of seismoreceiver, substantially increase linear, stability during seismoreceiver work.
