Abstract
The utility model discloses a multi component isoplanar radial displacement type boring strain gauge, belonging to the field of the monitor of the stratum strain. The utility model solves the technical problem that at present multi radial displacement sensors in a multi component boring strain gauge are not installed on the same plane surface in a probe from top to bottom, so that each radial displacement sensor has different sensitivity coefficient responsive to the stratum strain, influencing the accuracy of the reducing calculus of the strain value of the measured value of each sensor. A cylindrical probe (1) is installed and connected with a radial displacement sensor (2) distributed with at least two crossed equant circumferential angles, and both ends of the radial displacement sensor distributed with crossed equant circumferential angles is connected with the cylindrical inner wall of the cylindrical probe on the same plane surface vertical to the axial line of the cylindrical probe. The utility model is mainly used for the observation in the research field of the strain solid tide, the earthquake strain step and the earthquake prediction, and is also applicable for the observation of the stratum strain in the aspect of engineering application.
Description
(1) technical field: the utility model belongs to stratum strain monitoring field.
(2) background technology: past deformation observation, adopt pantograph, because volume size is very big, need the long cavern chamber of tens of rice to install, cause pantograph construction costs height, deficiencies such as maintenance management inconvenience are installed; Along with science and technology development,, make perpendicular to radial displacement strainmeter observation crustal deformation technology is installed in the ground level boring to be rapidly developed in recent years owing to the appearance of radial displacement strainmeter.Dependent variable for the observation formation plane vertical with drilling axis, autocratic radial displacement formula drilling strain gauge need be adorned the radial displacement transducer of a plurality of different directions vertical with this probe axis in the probe cylinder, for the radial displacement transducer of above-mentioned a plurality of different directions is installed, have to the to extend cylinder pipe range of probe, installation from top to down, the radial displacement transducer that causes a plurality of different directions is not at grade, as the three-component drilling strain gauge in the vertical ground petrosal foramen of being contained in of Australian Gladwin development, three radial displacement transducers are installed in the top of probe respectively, middle part and lower position.Four radial displacement transducers also are arranged in from top to bottom on four different planes in China's existing RZB-1 type drilling strain gauge.The position of each radial displacement transducer in probe has nothing in common with each other, distance apart from the probe edge is different, because of the edge effect influence, make each radial displacement transducer have nothing in common with each other to the sensitivity coefficient of stratum strain response, and difference therebetween is very difficult accurately definite, has influence on the precision of using each radial displacement transducer measured value reduction strain value.According to another report: " globe lens " plan that the U.S. began to carry out in 2003 is classified many components radial displacement formula drilling strain gauge as main optical viewer.Mostly adopt many components radial displacement formula drilling strain gauge observation crustal deformation both at home and abroad, various countries are all improving new design at above-mentioned weak point, but also do not come out at present.
(3) summary of the invention: technical problem to be solved in the utility model: the two ends of a plurality of radial displacement transducers of dress in many components radial displacement formula borehole strain instrument probe is installed on the same plane of cylindrical shape inner probe wall perpendicular to this probe axis, thereby make the response sensitivity coefficient unanimity of each radial displacement transducer, improve measuring accuracy, shorten cylindrical shape probe axial length simultaneously, reduce cylinder type probe weight, easy to use with install, reduce cost.
The technical scheme that solves the problems of the technologies described above: develop many components isoplanar radial displacement formula drilling strain gauge, it comprises probe and is installed in the interior radial displacement transducer of probe, radial displacement transducer is made up of electric capacity micrometer stator, electric capacity micrometer moving plate and drive link, it is characterized in that being installed in the radial displacement transducer that the Equal round round angle that has two grade separations in the cylindrical shape probe at least distributes, and the two ends of the radial displacement transducer that distributes of the Equal round round angle of grade separation and the cylindrical shape cylinder shape inner wall of popping one's head in is connected on the same plane perpendicular to the cylindrical shape probe axis.
The beneficial effects of the utility model: 1,, make the response sensitivity coefficient unanimity of each radial displacement transducer, improved measuring accuracy because the two ends of a plurality of radial displacement transducers is installed on the same plane perpendicular to the cylindrical shape probe axis; 2, because the utility model design makes a plurality of radial displacement transducers that are installed in the cylindrical shape probe realize that grade separation just makes the two ends of a plurality of radial displacement transducers can both be installed on the same plane perpendicular to the cylindrical shape probe axis, make the cylindrical shape probe under the prerequisite that does not influence measurement performance, shorten length, reduce weight, easy to use with install, thereby reduced cost.
