The episphere is equipped with half ball seal groove with the closed department of lower semisphere, and half ball seal inslot is equipped with sealed O type circle, forms the ball -type shell of uniform thickness after episphere and the lower semisphere closure. The shell structure of its ball -type makes it measure to each looks same sex, and the angle is installed wantonly, the line strain of the arbitrary orientation of measurable quantity. A line strain is measured for passing through drilling pouring coupled modes is to wantonly to the earth deformation.
Description
Technical field
This utility model relates to a kind of Mechanics of Machinery structure, electronic measurement system, particularly relates to a kind of ball-type arbitrarily to earth deformation measurement instrument.
Background technology
In geophysics and geodesic survey, commonly used boring quasi-instrument, to the crustal stress in boring, crustal strain measurement. In measurement, first punch in earth's crust detected part, then test probe is transferred to treat gaging hole section, use cement casting mode to be coupled with hole wall by measuring probe, make probe reach with hole wall to weld the boundary condition coupled. So, in boring, the deformation of rock will be delivered on probe, and stress-strain measurement probe reaches the purpose measured according to this deformation.
In order to adapt to measure the requirement of environment and measurement, the mechanical structure of this quasi-instrument needs meet isotropy or measure other direction concrete moduli order of magnitude lower of direction ratio. Owing to boring is all cylindrical structural, therefore the profile of measuring probe is also all cylindricality, and its horizontal direction equivalent elastic modulus is lower than axial and other directions, and therefore level is comparatively difficult to strain measurement in addition.
Utility model content
The purpose of this utility model is to provide a kind of capable of arbitrary angle mounting ball-type arbitrarily to earth deformation measurement instrument.
The purpose of this utility model is achieved through the following technical solutions:
Ball-type of the present utility model is arbitrarily to earth deformation measurement instrument, including episphere, lower semisphere, ball-type profile is formed after described episphere and lower semisphere Guan Bi, displacement transducer it is provided with in spherical shape, the roof of described episphere is provided with episphere top dome mounting seat, the roof lower semisphere top dome mounting seat of described lower semisphere, described episphere top dome mounting seat or lower semisphere top dome mounting seat are provided with top dome mounting seat line outlet.
The technical scheme provided by above-mentioned this utility model can be seen that, the ball-type that this utility model embodiment provides is arbitrarily to earth deformation measurement instrument, the shell mechanism of its ball-type makes it measuring to isotropy, arbitrarily angled can install, can measure the line strain of any direction. For passing through to hole cast coupled modes to arbitrarily measuring to the line strain of crust deformation.
Accompanying drawing explanation
The ball-type that Fig. 1 provides for this utility model embodiment is arbitrarily to the structural representation of earth deformation measurement instrument.
Detailed description of the invention
This utility model embodiment will be described in further detail below.
Ball-type of the present utility model arbitrarily to earth deformation measurement instrument, its preferably detailed description of the invention be:
Including episphere, lower semisphere, ball-type profile is formed after described episphere and lower semisphere Guan Bi, displacement transducer it is provided with in spherical shape, the roof of described episphere is provided with episphere top dome mounting seat, the roof lower semisphere top dome mounting seat of described lower semisphere, described episphere top dome mounting seat or lower semisphere top dome mounting seat are provided with top dome mounting seat line outlet.
The Guan Bi place of described episphere and lower semisphere is provided with hemisphere seal groove, is provided with sealing O in described hemisphere seal groove.
Described episphere forms the ball-type shell of uniform thickness with lower semisphere after closing.
Ball-type of the present utility model is arbitrarily to earth deformation measurement instrument, and the shell mechanism of its ball-type makes it measuring to isotropy, arbitrarily angled can install, can measure the line strain of any direction. For passing through to hole cast coupled modes to arbitrarily measuring to the line strain of crust deformation.
In upper and lower hemisphere top dome mounting seat can fixed displacement sensor draw wire, there is seal groove at upper and lower hemispheres Guan Bi place, can seal by mounting O-shaped rings, upper and lower hemispheres fixed displacement sensor after closing, and namely forms airtight ball-type space. Its ball-type external form isotropy on mechanical structure, therefore can arbitrarily angled installation in the borehole, use after cement builds coupling, can measure arbitrarily to line strain.
Specific embodiment:
As shown in Figure 1, ball-type is arbitrarily measured to earth deformation measurement instrument for the line strain that the deformation of institute installation region carries out any direction, including: episphere (1), lower semisphere (2), episphere top dome mounting seat (3), lower semisphere top dome mounting seat (4), displacement transducer (5), top dome mounting seat line outlet (6), hemisphere seal groove (7), sealing O (8).
In work, being first assemblied in lower semisphere mounting seat (4) by displacement transducer (5), sensor fixed by lock-screw, and draws wire (6) from mounting seat line outlet. Covering on lower semisphere (2) by episphere (1) again, there is seal groove (7) at upper and lower hemispheres Guan Bi place, can seal by mounting O-shaped rings (8); Use lock-screw locking displacement transducer upper end, upper and lower hemispheres (1) (2) closed spheroiding confined space.
Its ball-type external form isotropy on mechanical structure, therefore can arbitrarily angled installation in the borehole. After using cement to build coupling, can measure arbitrarily to line strain. In actual use, first ball-type is arbitrarily placed in boring to be measured to earth deformation measurement instrument, adjust and measure direction, joints cement, it is made to form, with drilling rock, the boundary condition that welding couples, now the measuring instrument of isotropic just produces corresponding deformation according to the deformation of drilling rock, and its internally installed displacement transducer just can measure axial line strain.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
