Description
Technical field
The invention belongs to the electrical equipment sensor field; Relate to a kind of vibration transducer that utilizes inertia vibration measuring principle to make; Be widely used in the industries such as coal, electric power, oil, chemical industry, metallurgy, traffic, building, war industry the long-term vibration monitoring and the protection of instrument, equipment, be used in particular for system's online automatic detection warning system.
Background technology
The sensor of measuring vibrations can be divided into: vibration displacement sensor, vibrating speed sensors and vibration acceleration sensor.Different according to the test reference coordinate, vibration-measuring sensor can be divided into two types of relative formula vibration-measuring sensor and absolute type vibration-measuring sensors again.The former is used for the motion of its vibration reference point relatively of measuring vibrations body, and the latter is used for the motion of measuring vibrations body with respect to the earth or inertial space.The absolute type vibration-measuring sensor is because inside comprises inertial mass, so be called the inertia-type vibration-measuring sensor again.
Although all kinds of inertia-type vibration-measuring sensor theory structures are not quite similar; But they all have a common ground; That is exactly that sensor base all is fixed on the tested vibrating mass, and sensor internal all has a mass, and mass all passes through spring or other elastic bodys link to each other with sensor base; The absolute motion of vibrating mass is through producing relative motion between spring band kinoplaszm gauge block and the base, and its relative motion receives the damping action of sensor internal damping device.Constituted the inertia motion system by mass-spring-damper.
Patent documentation 1 described below discloses the vibration transducer based on magnetic suspension principle.Following method has been shown in the document: a permanent magnet is suspended in another piece magnet top; The magnetic direction of two permanent magnets is opposite; The below magnet is fixed on the tested vibrating mass and responds to external vibration; Coil stationary on vibration transducer, and is placed the coil centre position with end face of this levitated magnet.Maglev magnet is with respect to the magnet generation relative motion of being fixed in the sensor when the sensor sensing external vibration, and coil produces the induction electromotive force that is directly proportional with vibration velocity.
In addition; In the patent documentation 2 shown in following, show following formation: mainly by housing and in sensing element and the control circuit established form, housing is docked by two cylinders that are provided with semi-circular recesses each other to be formed; The sensing element that on the mutual interface of two cylinders, accompanies; Be divided into two semisphere chambers to housing, in two chambers, respectively be equipped with the steel ball that quantity equates.When vibration takes place, can detect vibration data through the interior senser element of establishing.
Patent documentation 1: Chinese patent " based on the vibration transducer of magnetic suspension principle ", the patent No. 200520047887.6.
Patent documentation 2: Chinese patent " universal vibration transducer ", the patent No. 97226930.4.
Through adopting above-mentioned formation; Can measure the vibrational state under level or the vertical state, but vibrate when taking place the weak output signal that traditional inertia electromagnetic type detection method obtains; And be simulating signal, need through just obtaining data after the complicated amplifying circuit processing.For the endosphere pick-up unit and since each ball when rolling each ball position be difficult to correspondingly with direction of vibration accurately, the quantity of senser element also has bigger influence to accuracy as a result.
Summary of the invention
The present invention proposes in view of the above problems, and purpose is to provide a kind of vibration transducer, can detect the vibration signal of four direction, and it can not reduce the sensitivity that detects vibration, and can directly obtain digital signal, and signal processing circuit is simple.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of inside sphere type vector vibration transducer is provided with four through holes at a hollow on-insulated spheroid spherical container; Four summits of positive rectangular pyramid have been constituted between four through holes; Difference fixed leg form point touch sensor in four through holes, the point contact type sensor construction is: hexagon head bolt can connect the outside lead contact and be hung into the point contact type sensor, and the top of collision connecting rod top and link supports spring is fixed; Collision connecting rod bottom is fixed with collision connecting rod hook ring, and the bottom of the bottom of link supports spring and point contact type sensor is fixed.Spherical oscillator places in the spherical insulation crust, has four oscillator lines with length that oscillator is connected with collision connecting rod hook ring.
1, in such scheme; When the collision connecting rod does not receive pulling force; On the contact of pushing up the hexagon head bolt bottom under the effect of link supports spring, when the collision connecting rod received pulling force, the elastic force size of link supports spring will guarantee to leave the contact of hexagon head bolt bottom.
2, in such scheme, spherical oscillator makes oscillator charged through the outside lead of introducing of on-insulated spherical container.
3, in such scheme, the combination of 16 kinds of digital signals through four the point contact type sensors in space can realize the detection of 16 directions in theory.
Because the application of technique scheme, the present invention compared with prior art has advantage:
1, because employing of the present invention; On the spherical oscillator with on suitable voltage, during oscillator vibration, four point contact type sensors can directly obtain tangible digital signal; Make corresponding signal processing circuit save the signal amplifying part branch; Thereby reduced production cost, also improved sensitivity simultaneously, improved the reliability of system.
2, because the action of the collision connecting rod that causes of charged spherical oscillator vibration all is insulated shell shields, so the explosion-proof performance of system is superior.
3, the present invention is simple in structure, and is easily manufactured.
