Description
Technical field
The present invention relates to observation instrument is learned a kind ofly, it is adapted for mount on foot of hole, the small skew of the measured zone earth's crust
Variation, for monitoring the preparation process of the dependent events such as tectonic earthquake, volcanic earthquake, reservoir-induced earthquake.
Background technique
For the earth inclination measurement bore inclining visualizer there are many, basic working method is in a long round metal
In cylinder, two or more inclination sensors are from top to bottom installed, are mounted on brill using mechanical claw or cement consolidation style
Hole bottom measures two parameters of the earth tilt angle: the angle with gravity directionThe level orientation at inclination angle and geographic north
Angle θ.This mode high-precision continuous tilt measurement application in have one it is clearly disadvantageous: when a sensor mechanically and electrically
When subsystem reliability reduces, slowly varying and true tilt greatly of appearance is obscured together, can not effectively be known
Data analysis is not influenced.The local researcher for learning measurement expert Su Kai of Earthquake In China proposes improved method: three sensors are pressed
It is laid according to isosceles triangle, the inclination angle and direction that any two sensor can calculate the earth are obtained when instrument system is normal
To three groups of identical calculated results, and the inclination angle that three sensor measurements arriveAnd perseverance be zero (Su Kai
Earthquake Press 2003 drill crustal strain observe new development P211).
The concise formula of its tester system reliability are as follows:
Traditional structure is the pendulum mass bracket of steel cylinder built-in suspension, hangs pendulum mass in pendulum mass bracket, pendulum mass frame bottom by
Drive system control, the adjusting for doing two horizontal directions all around makes sensor reach measured zone, because structure is complex,
Itself transience is relatively more, both direction inclination sensor, can not accomplish that own reliability verifies, three biographies of minority installation
The probe own reliability verification the verifying results of sensor are also undesirable, cause the reason of system own reliability verification the verifying results difference to be mainly
The problem of in terms of mechanical structure.
Summary of the invention
Ability is verified to improve borehole inclinometer own reliability, the present invention provides a kind of simple bore inclining survey of structure
Instrument is measured, the alloying metal cylindrical rod of excellent in stability is selected to do pendulum mass bracket, designs three in metal cylinder stick same level height
A inclination sensor is installed in the borehole and guarantees long-term stability using traditional cement consolidation.
The technical scheme is that pendulum mass bracket is done using diameter 110mm metal cylinder material, in the axle center of metal cylinder
Around, three pendulum mass mounting grooves are processed with numerically controlled wire cutting machine, indexing processing is carried out by numerically-controlled machine tool, 0.01 ° of indexing accuracy;
Pendulum mass cradle top designs three and leans on motor-driven support rod, realizes mechanical fine adjustment and the locking of dipmeter;Pendulum mass bracket bottom
Portion designs three claws, and claw is strutted by the self weight of pendulum mass bracket and is stuck on the borehole wall.
The beneficial effects of the present invention are: doing the pendulum mass timbering material of inclination instrument using metal cylinder stick, numerically-controlled machine tool is leaned on
Positioning makes three inclination measurement component installation locations obtain accurate position indexing;There are three tops with motor-driven support
Probe is fixed on the borehole wall of drilling by bar, three support rods after stretching out, and three support rods can independently be adjusted, and probe is allowed to arrive
Up to plumbness, it is in three sensors and works normally section;Bottom is fixed on by bottom three by being self-possessed distracted claw
On the borehole wall.After installation and debugging are stablized, probe is consolidated using self-stressing cement, is reduced unstable caused by mechanical structure
Factor, cement consolidation can make three inclination measurement units obtain preferable reliability demonstration effect with simple structure.

Specific embodiment
In Fig. 1, pendulum mass bracket (1), cable gland (3), Europe type ring (6), shell (14), constitutes one at cable (2)
Seal cavity, guaranteeing to seep water in shaft bottom leads to instrument damage;Pendulum mass bracket (1) is intermediate, and there are three trough, the interior installations of trough
Three pendulum masses (10), 120 ° of the angle of three troughs, pendulum mass are used as (intermediate) movable plate of tri-electrode capacitance sensor, pendulum simultaneously
Body two sides are capacitance sensor stator (11), and stator is embedded in pendulum mass bracket, when pendulum mass (10) position is among two stators
When, circuit (7) output is zero, and output is negative value when being biased to pendulum mass carriage center, it is output to the outside partially as positive value, what circuit generated
Electric signal is transported to ground by cable (2);Pendulum motor (12) and lock swing rod (13) composition lock oscillator system are locked, when lock pendulum motor turns
It is dynamic pendulum mass to be held up and fixed when lifting lock swing rod, it is easy to carry;Top is made of turbine (4), support rod (5), motor (18)
Instrument micro-tensioning system, three 120 ° of regulating system angle;Bottom is made of guide rod (15), claw (16), claw cone of support (17)
Self-centering fastening system, it is three 120 ° of claw angle, clear in order to illustrate, the signal of claw is only provided in drawing, when
When claw cone of support (17) reaches shaft bottom, probe continues to decline, and guide rod (15) glides along claw cone of support inner hole, passes through connection
Bar struts claw (16), and three claws strut conflict to the borehole wall simultaneously, holds out against claw by probe own wt.
Referring to fig. 2, A-A section, three support rods (5) are in 120 ° of angles, and support rod drives turbine (4) to drive by motor (18)
Dynamic to move in the axial direction, turbine (4) and motor (18) are embedded in pendulum mass bracket (1), with food-grade lubricating grease blind,
Prevent dust and impurity from entering.Support rod (5) are adjusted with motor (18), until the position of three pendulum masses (10) to the centre of stator
Position;B-B section, insulating ceramics block (08) snap fit onto pendulum mass bracket (1), insulating ceramics block, and two pieces one group, for fixed pendulum
Body suspension line (09), pendulum mass are hung by two suspension lines;C-C section, three pendulum masses (10) and sensor stator (11) composition three
A independent capacitance displacement sensor.Capacitance sensor principle is common structure, no longer knows and states.
It should be noted that structure in the present invention is only when measuring tilt angle varied less than 0.05 °, the fortune of three pendulum masses
The relationship of moving is in strict conformity with formula (1).
In the region that crustal rock is stable, the earth tilts year variation less than 1 ", since having record, there has been no inclination angles to be greater than 2 "
Volcano and tectonic earthquake precursory anomaly, the capacitance displacement sensor resolving power of the design be designed as 10-4", range ± 100 ", it moves
