Background technology
What the seismoreceiver in seismic prospecting adopted is the passive electromagnetic induction, Stability Analysis of Structures, and reliability is high, and superiority of effectiveness is obvious.Because the ground observation circumstance complication extends to the ocean from high mountain, lake, Gobi desert always, and four seasons construction, temperature range alters a great deal, and requires seismoreceiver under-40 ℃～+ 80 ℃ environment, to work.Seismoreceiver is the feeler of seismic acquisition, it stable extremely important.
At present, though wave detector can satisfy request for utilization basically, in the common counter of seismoreceiver, except the relation of frequency and degree of distortion and temperature was smaller, resistance, ratio of damping, three important indicators of sensitivity all changed with temperature variation.Relatively more accurate wave detector, from-40 ℃ to+80 ℃ temperature variation, all about 7%, the rate of temperature change of resistance is more about 14% for the rate of temperature change of ratio of damping and sensitivity; The operation mode of seismoreceiver also will change with the variation of these three parameters, and the Information Monitoring meeting changes.
The utility model content
The purpose of the utility model is: the seismoreceiver that provides a kind of resisting temperature to change makes seismoreceiver in-40 ℃～+ 80 ℃ environment, reduce the influence of environment temperature to Information Monitoring.
The technical scheme that the utility model adopts is: the seismoreceiver that resisting temperature changes; Mainly form by magnet, temperature compensation ring, last yoke, lower yoke, coil former, upper spring sheet, lower spring sheet, shell, loam cake, lower cover, binding post and resistance; Lower end at cylindrical housing is fixed with lower cover; In the lower cover upper end annular step is arranged; On the annular step of lower cover, the lower spring sheet is arranged, tubular lower yoke is arranged, the coil former of annular is arranged around lower yoke at the top of lower cover; There is a tubular magnet on the plane on lower yoke; The tubular yoke of going up is arranged at the top of magnet, and the coil former of annular is arranged around last yoke; On the top of coil former the upper spring sheet is arranged, on the top of upper spring sheet and last yoke loam cake is arranged, the edge of loam cake is fixed on the upper end of shell; On be stamped two axial holes, in two axial holes of loam cake, a binding post is arranged respectively.On the top of loam cake a cover plate is arranged, two binding posts pass cover plate; It is characterized in that: be with the temperature compensation ring of an annular at the outer wall of magnet, temperature compensation ring and magnet are formed built-up magnet, and temperature compensation ring upper end is enclosed within on the right cylinder outer wall that protrudes the yoke lower end; Temperature compensation ring lower end is enclosed within on the right cylinder outer wall of lower yoke upper end protrusion; Through lead and two binding post welding, in use resistance is parallelly connected with the negative temperature coefficient instrument respectively for two utmost points of resistance.When environment temperature raise, the magnetic output of this group built-up magnet strengthened.The resistance value of resistance raises with temperature and reduces.
The external diameter of shell is between 22～28mm, and internal diameter is between 21～24mm, and height is between 22～28mm.The resistance of resistance is between 900～1000 Ω.
The beneficial effect of the utility model: the seismoreceiver that the utility model resisting temperature changes; Adopt unique subzero temperature resistive technologies and built-up magnet over-compensation technology; The parameter of seismoreceiver is dropped to minimum with temperature changing trend, make the earthquake-capturing effect more stable in the environment of temperature variation.
