Description

Novel nonmagnetic rotary platform

Technical Field

The utility model relates to a rotary platform technical field especially relates to a novel no magnetism rotary platform.

Background

Geomagnetic observation data is widely applied to the research fields of geoscience, space physics and the like, and national defense and national economic construction such as aviation, aerospace, communication, mineral resource investigation, underground pipe networks, power grids, petroleum drilling, earthquake prediction and the like, at present, 153 geomagnetic stations are shared in national geomagnetic station networks, and 165 sets of fluxgate magnetometers are arranged in more than 300 sets of geomagnetic relative recording instruments operated by the networks.

The existing research shows that two error sources of the accuracy of the observation data of the fluxgate magnetometer are respectively the existence of positive angle errors and zero field drift values of three axial directions in a probe, an original nonmagnetic rotary platform is specially designed and manufactured for an FHD instrument chassis, the accurate rotation of the probe by 180 degrees is difficult to ensure because the resolution ratio of an FHD dial is relatively low, a large measurement error exists when the zero field drift value is measured, and the original nonmagnetic rotary platform can not realize the measurement of the positive angle errors of the three axial directions of the fluxgate magnetometer probe (namely, included angles of all axial directions generated in respective horizontal planes).

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that exists among the prior art, two error sources of fluxgate magnetometer observation data accuracy, be the existence of three axial positive angle error and zero field drift value in the probe respectively, former no magnetism rotary platform is special for FHD instrument chassis design and preparation, still relatively lower because of the resolution ratio of FHD circle itself, hardly guarantee the accurate 180 that rotates of probe, there is great measuring error when measuring zero field drift value, former no magnetism rotary platform can not realize the measurement of the three axial positive angle error of fluxgate magnetometer probe (the contained angle that each axial produced in the horizontal plane separately promptly).

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a novel no magnetism rotary platform, includes test platform, test platform includes connecting seat, support and test disc, the support mounting is at the top of connecting seat, the test disc passes through the support and is connected with the connecting seat.

As a preferred embodiment, the outer surface of the connecting seat is provided with a plurality of threaded holes.

The technical effect of adopting the further scheme is as follows: the connecting seat is used for connecting the test disc and the nonmagnetic theodolite telescope part into a whole, and the threaded holes are formed to facilitate the threaded connection of the connecting seat and the nonmagnetic theodolite telescope.

In a preferred embodiment, the outer surface of the test disc is provided with three V-shaped grooves in an annular array at the center of the test disc.

The technical effect of adopting the further scheme is as follows: the three V-shaped grooves arranged on the surface of the test disc can effectively control and stabilize the position of the probe.

As a preferred embodiment, the connecting seat, the bracket and the test tray are connected through external bolts.

The technical effect of adopting the further scheme is as follows: through bolt swing joint's mode, the user of being convenient for dismantles or installs connecting seat, support and test disc.

Compared with the prior art, the utility model has the advantages and positive effects that,

the utility model discloses in, fix test platform on no magnetism theodolite, can measure fluxgate magnetometer probe's zero field drift value more accurately, three axial produces the contained angle in plane separately in can the measuring probe simultaneously, improves fluxgate magnetometer observation data precision.
