Background technology
The same with conventional sensors, it is necessary to calibrate to it before using seismometer.The general seismometer calibration cycle
For 1 year, to ensure the property indices of seismometer it is ensured that geological data accuracy of observation and observed reliability.Wherein, over the ground
One important content of shake meter calibrating is exactly that the vertical component to seismometer carries out low frequency characteristic test, that is, pass through to increase Vertical Vibrating
Dynamic platform vibratility adjustment, to improve the signal to noise ratio of seismometer test, realizes the detection to seismometer vertical component low frequency characteristic.
On market, seismometer size and dimension is different, continuous especially with seismometer use requirement and serviceability
Improve, the diameter of some large scale seismometers has been far longer than the diameter of vertical vibration table table top, and vertical vibration table is to such
Large scale seismometer cannot be carried out effectively big stroke vertical vibration test, had a strong impact on large scale seismometer detection and
Normal use.Then, extending design is carried out to existing seismometer test vertical vibration table, just become this utility model and want to solve
Problem.
Content of the invention
In view of the foregoing, this utility model aims to provide a kind of seismometer test vertical vibration with extension table top
Platform, to meet the vertical vibration testing requirement of large scale seismometer, the suitability of vertical vibration table tested by the existing seismometer of extension.
This utility model solves its technical problem and be the technical scheme is that
Vertical vibration table tested by modified model seismometer, including vertical vibration table stage body, also includes the sky of a surface hollow-out
Heart cylinder, a disc workbench and a plane mirror, the bottom of hollow cylinder is fixedly connected on vertical vibration table stage body
On work surface；Disc workbench is fixedly connected on the top of hollow cylinder, and disc workbench keeps level；Disc works
The surface of platform is provided with the x direction v shape groove of one or more, and a y direction v shape groove perpendicular with x direction v shape groove；Plane
Mirror is fixed on the outer side edges edge of disc workbench, and the minute surface of plane mirror is upward.
Described y direction v shape groove is located on the bisector of x direction v shape groove.
Described y direction v shape groove is non-intersect with x direction v shape groove.
Described x direction v shape groove runs through whole disc workbench.
Vertical vibration table tested by modified model seismometer described in the utility model, by original vertical vibration table stage body
Connect hollow cylinder and disc workbench on work surface, so that the workbench of vertical vibration table is extended, meet large scale earthquake
The vertical vibration test installation requirements of meter, meanwhile, workbench after amplification, also can greatly increase the vibration signal input of seismometer
Intensity is it is ensured that the low-frequency test precision of large scale seismometer.It is arranged on a plurality of x direction v shape groove and the y side on disc workbench
To v shape groove, except simple structure, easy to use in addition to, using the cooperating of v shape groove and three legs of seismometer, clamping, can be formed
Stable gusseted, meets dither test needs, simplifies the installation of seismometer it is ensured that vertical vibration was tested
The accuracy of journey and reliability, can be suitable for various types of seismometer detections and use.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the mounting structure schematic diagram of disc workbench and plane mirror in this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings 1, Fig. 2 is described in further detail to this utility model:
Vertical vibration table tested by modified model seismometer described in the utility model, including an existing vertical vibration table platform
2, disc workbench 3 of the hollow cylinder of 1, surface hollow-out of body and a plane mirror 4.Wherein, hollow cylinder 2 is used for
Increase the working depth in vertical direction for the vertical vibration table stage body work surface, to improve vertical vibration table stage body 1 in vertical direction
Vibratility adjustment.Disc workbench 3 uses as the work top of vertical vibration table after improving.Plane mirror 4 is then swashed with the external world
Optical interferometer is coordinated, and completes the vibration displacement monitoring of disc workbench 3 in vibration processes.
Concrete structure is: the bottom of hollow cylinder 2 is bolted to connection the work surface in vertical vibration table stage body 1
On, disc workbench 3 is fixedly connected on the top of hollow cylinder 2, and disc workbench 3 keeps level, the height of hollow cylinder 2
Degree is exactly the vibration displacement amplification of vertical vibration table after improvement.Measure during examination in disc workbench 3 for simplifying earthquake further
On fixation procedure, in this example, be additionally provided with five x direction v shape grooves 5 on the surface of disc workbench 3, x direction v shape groove 5 passes through
Wear whole disc workbench 3, and, be additionally provided with a y direction v shape groove 6, y side in the direction perpendicular with x direction v shape groove 5
It is located on the bisector of x direction v shape groove 5 to v shape groove 6, y direction v shape groove 6 is non-intersect with x direction v shape groove 5.V shape groove be used for
Three legs of seismometer match, and complete the triangle horizontal stable to seismometer and support.Plane mirror 4 is fixed on disc work
The outer side edges edge of platform 3, the minute surface of plane mirror 4 upward, and is matched with the laser interferometer at extraneous top.
During specific works, first a leg of seismometer is positioned in y direction v shape groove 6, two other leg is corresponding
Place wherein in an x direction v shape groove 5, v shape groove shape limit and the collective effect of leg supported at three point under, seismometer
Stably it is supported on disc workbench 3.Then, vertical vibration table stage body 1 and laser interferometer are opened, by vertical vibration
Work surface vibration on platform stage body 1 drives hollow cylinder 2 and disc workbench 3 vertical vibration.Finally, in laser interferometer
Under monitoring, seismometer vertical vibrating velocity under different frequency is detected, complete the check and correction of seismometer vertical vibration process.
Increase the seismometer after face height and test the installation that vertical vibration table not only adapts to large scale seismometer, also
The vibration signal input intensity of seismometer can be greatly increased it is ensured that the low-frequency test precision of large scale seismometer.
