The technical scheme that its technical matters of the utility model adopts is: construct a kind of tiltmeter with the microscope micrometer, comprise tiltmeter main body and micrometer device, the tiltmeter main body is the vertical pendulum tiltmeter, comprise support, pendulum system, pendulum system is suspended on the vertical pendulum system that the hang spring of a top of the trellis consists of by pendulum, the micrometer device is made of index dial and optical microscope, and described microscopical object focal point overlaps with the initial point of index dial, and the tuning drive gear of pendulum is over against the true origin of index dial.
In the tiltmeter with the microscope micrometer described in the utility model, the scale of described index dial be by a series of take true origin as the center of circle, the concentric circles of radius equal difference consists of.
In the tiltmeter with the microscope micrometer described in the utility model, described pendulum is cone, and the cone tip is provided with an elongated pointer, and pointer and hang spring, pendulum center of gravity are on a pedal line.
The another kind of technical scheme that its technical matters that solves the utility model adopts is: reach a kind of tiltmeter with the microscope micrometer, comprise tiltmeter main body and micrometer device, the tiltmeter main body is horizontal pendulum tiltmeter, comprise that level is communicated with the horizontal pendulum system that consists of, the micrometer device is optical microscope, and microscopical object lens are over against the pointer of sign level liquid level in communicating pipe.
The utility model is compared with existing tiltmeter, has following advantage:
1, the utility model adopts optical microscope that the graduated scale of tiltmeter is amplified, and makes tiltmeter that high measurement accuracy and sensitivity be arranged.
2, the utility model is simple with the tiltmeter assembling of microscope micrometer.
The direction that can tilt again when 3, the utility model can be observed angle of inclination, ground size with the tiltmeter of microscope micrometer with observing.
4, cheap for manufacturing cost with the tiltmeter of microscope micrometer in the utility model.

Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of tiltmeter among first embodiment of the utility model.
Fig. 2 is the structural representation of the index dial of tiltmeter among first embodiment of the utility model.
Fig. 3 is the structural representation of tiltmeter among second embodiment of the utility model.
Embodiment
Fig. 1, Fig. 2 show first embodiment of the present utility model.
See also Fig. 1, shown in Figure 2, in the utility model, tiltmeter with the microscope micrometer, comprise tiltmeter main body 20 and micrometer device, tiltmeter main body 20 is the vertical bank instrument, comprises support and pendulum system, pendulum system is to be made of circular cone pendulum 23 and hang spring 22, hang spring 22 is suspended on the top of support 21 with circular cone pendulum 23, and the tip of circular cone pendulum 23 is provided with elongated pointer 231, and pointer 231 coexists with hang spring 22, pendulum center of gravity on the pedal line.Pointer 231 points to the true origin of index dial 24.The micrometer device is optical microscope 10, and the object focal point of microscope 10 overlaps with the initial point of index dial 24.
Scale on the index dial 10 be a series of take true origin as the center of circle, the concentric circles of radius equal difference, this concentric circles radius is take millimeter as unit.Index dial 24 is made by corrosion resistant sheet metal and is formed, and the surface is through optical grinding.
During the utility model assembling, first index dial 24 is placed under the object lens of microscope 10, and the object focal point of microscope 10 is overlapped with the center far point of index dial 24, and also adjust the direction of index dial 24 simultaneously, make the four corners of the world direction of indicating on the index dial be actual direction.Then it is true origin that the balance regulator 25 of regulating support makes the center of the pointed index dial on circular cone pendulum 23 tips.
When the ground run-off the straight changed, because circular cone pendulum 23 and hang spring 22 keep vertical direction, therefore, certain skew can occur with respect to the degree of index dial base area face tilt in circular cone pendulum 23.Position by the pointer indication on microscope 10 observations and the record conical tip, read the distance of conical tip pointer 231 off scale disk center, and according to the length of the height of the length of hang spring 22, circular cone pendulum 23 and pointer 231 and microscopical actual enlargement factor (when calculating, microscopical enlargement factor is irrelevant with the calculating that ground tilts, microscope just amplifies scale, be convenient to observed reading), just can calculate the angle (rad) of terrain slope.
The utility model is owing to adopted the trickle skew of 10 pairs of circular cone pendulums 23 of microscope to amplify, can improve widely the measuring accuracy of tiltmeter, circular cone pendulum 23 can be done the skew of any direction simultaneously, only needs size and the direction that such vertical pendulum tiltmeter just can tilt definitely.
The vertical pendulum tiltmeter that utility model people uses in the present embodiment is surveyed experiment at 1975-1978 in these 3 years.Utility model people is according at that time measurement result, successfully to making forecast when the 6.9 grades of earthquakes in 5.6 grades of Lulongs, Hebei on the 12nd November in 1976 and Ninghe, Tianjin on the 15th.Utility model people according to vertical pendulum tiltmeter observed result in conjunction with the success of automatic current instrument observed result to carry out prediction about imminent earthquakes tens of time and sum up a cover: the time be several hours to a week; The place is in the 600KM circumference; Earthquake magnitude is the above prediction about imminent earthquakes method of 3-7 level, and only has wrong report not fail to report in the situation of not getting rid of at that time the interference experience.Infer that for this reason it is feasible prediction about imminent earthquakes.
Fig. 3 shows second embodiment of the present utility model:
See also shown in Figure 3, in the utility model, tiltmeter with the microscope micrometer, comprise tiltmeter main body 30 and micrometer device, tiltmeter main body 30 is the horizontal pendulum tiltmeter, comprise the horizontal pendulum system that is made of level communicating pipe 31, the micrometer device is optical microscope 10, and the object lens of microscope 10 are over against the pointer of sign level liquid level in communicating pipe.The horizontal pendulum tiltmeter is that to utilize level be the principle of level under field conditions (factors), when the run-off the straight of ground, level communicating pipe 31 is also with terrain slope, but the liquid 32 in it still keeps level, liquid and the relative variation of level communicating pipe 31 cause the variation of the 33 relative communicating pipes of float in level communicating pipe 31, thereby make pointer indicate the height change of liquid level at rule 34, in the utility model, adopt microscope that the slight change of pointer indication scale is amplified, thereby improve the measuring accuracy of tiltmeter, accurately tilt parameters is provided.
