The invention is the tailstock of the sensor used for the seismic exploration or the vibration test, which can fix a miniature high-performance sensor at the surface of a medium to be tested conveniently, also avoids influencing the response performance of the sensor as far as possible and has flexible installation and insertion, stable support, simple structure, convenient manufacture and reliable performance.
Description
Technical field
The present invention relates to a kind of seismic prospecting or Non-Destructive Testing field with the device that sensor installs and fixes, be particularly suitable for faint various small-sized high sensor affected by magnetic fields, as piezoelectric acceleration sensor.
Technical background
The seismic prospecting detector performance directly influences the usefulness of high-resolution seismic survey.Widely used sensor is a mechanical type magnetoelectricity speed pickup in the seismic prospecting, and such sensor is cheap, easy for installation, and its advantage is arranged in the practical application in the open air.But there are two big defectives in this class sensor self, the one, and monomer sensor is owing to the design limitation on its principle, and sensitivity is difficult to surpass 0.30V/ (cm/s); The 2nd, Frequency Response exists phase distortion and frequency span limited, and there is alias in such sensor frequency response characteristic about high frequency 300Hz, causes that useful signal is difficult to complete documentation in some seismic prospecting or the vibration-testing; The 3rd, the individual quality of sensor is big, has virtual masseffect in vibration-testing, influences vibration-testing and analytical effect.In addition, traditional mechanical type magnetoelectricity speed pickup inserts difficulty on the hard face of land, owing to can not make tail cone insert hard dielectric surface with impacting approach sensor, so inconvenience is also often arranged.
With the piezoelectric acceleration sensor is a class Miniature Sensor of representative, and its phase-frequency characteristic, amplitude versus frequency characte and sensitivity all are better than traditional mechanical type magnetoelectric transducer, because little, the light weight of its individuality, in being widely used in the high precision vibration-testing and analyzing; Greatest drawback is to lack the installation carrier, is difficult in the field environment to install and fix, thereby is limited in seismic prospecting is used.
Summary of the invention
Technical matters to be solved by this invention provides a kind of minitype high-performance sensor that can make and is fixed on tested dielectric surface easily, avoids influencing the seismic prospecting or the vibration-testing sensor tailstock of the response performance of sensor again as far as possible.
In order to address the above problem, seismic prospecting or vibration-testing sensor tailstock that invention provides, tail cone one end is provided with conehead, the other end is provided with the awl point, on conehead, be provided with pedestal, described pedestal is by making with the magnetic material of permanent magnetism iron phase suction, the center is provided with the depression platform, the base that contains permanent magnet material is fixedlyed connected with sensor, the slightly larger in diameter of described depression platform is convenient to the described base that contains permanent magnet material and is put into described depression platform in the described diameter that contains the base of permanent magnet material.
Described pedestal is connected with screw with the machine-shaping of described conehead one or by double-screw bolt.
Described tail cone is made by nonmagnetic substance.
Described sensor and the described base that contains permanent magnet material are connected and fixed by double-screw bolt and screw.
Adopt the seismic prospecting or the vibration-testing sensor tailstock of technique scheme, impact pedestal with hand hammer during use, it is surperficial fixing that tail cone inserts dielectric by the awl point, sensor by containing permanent magnet material base and the depression platform magnetic of tailstock be connected to the adsorption, finish sensor installing and fixing at dielectric surface.The sensor tailstock is whole light and handy, and except that pedestal was made with magnetic materials such as steel, remainder such as tail cone manufacturing materials can be various light wimet, reduced the additive effect of tailstock quality to sensor performance as far as possible.This invention tailstock extensively is suitable for various faces of land seismic prospecting data collecting occasion, also is adapted at the position fixation of sensor such as crag, base plate, top board of underground workss such as constructing tunnel.
The seismic prospecting or the vibration-testing sensor tailstock that use technique scheme to make mainly are suitable for the sensor that not influenced by external magnetic field, and it is inapplicable to resemble magneto-electric one class sensor.The size of tailstock or size can flexible design, have desirable Frequency Response and sensitivity to be advisable after guaranteeing that tailstock assigns under the fixing prerequisite, sensor and tailstock are fused.This invention tailstock extensively is suitable for face of land seismic prospecting data collecting occasion, also is adapted at the position fixation of sensor such as crag, base plate, top board of underground workss such as constructing tunnel.
In sum, the present invention is that a kind of minitype high-performance sensor that can make is fixed on tested dielectric surface easily, avoid influencing the response performance of sensor again as far as possible and assign flexibly, the seismic prospecting or the vibration-testing sensor tailstock of supporting ﹠ stablizing, simple in structure, easily manufactured, dependable performance.
