Detailed description of the invention
Fig. 1 is the structural schematic diagram of the steel tower holder orientation calibrating installation based on meteorological observation in one embodiment；
Fig. 2 is the schematic diagram of the steel tower holder orientation calibrating installation based on meteorological observation in one embodiment.
Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, and
It is not used in restriction the application.
In the conventional technology, according to surface weather observation specification, the wind transducer of automatic weather station is mounted on from earth's surface
On 10 meters of high steel towers, the bracket of wind transducer must install finger north mark face magnetic north horizontal and thereon.Due to
For compass in the interference apart from the closer space of steel tower by metal, needle indicates direction inaccuracy, installs wind direction sensing at present
When device bracket, it can only be pointed generally in magnetic north by ground north and south marking line or general guidance needle, error is easy to reach
To 5-10 °, for unfamiliar setter, error is bigger, significantly impact wind transducer measurement data accuracy and
The credibility of measurement data.The utility model passes through tune by the way that the principle of mirror image is utilized and designs mirror surface with a scale
Whole bracket simultaneously makes the direction of its diplopia accurately be directed toward magnetic north, realizes rack alignment magnetic north, error can be controlled in 1 ° with
It is interior.
In one embodiment, as shown in Figure 1, providing the steel tower holder orientation calibrating installation packet based on meteorological observation
It includes:
Horizontal mirror surface 110, horizontal mirror surface 110 are placed in ground level and are seen for observer to the mirror image of steel tower bracket
It surveys；
Compass 120, compass 120 are set on horizontal mirror surface 110 direction for being used to indicate earth magnetism south poles in parallel；
Reference line 130, reference line 130 are set to the surface of horizontal mirror surface 110 and pass through the center of compass 120.
Specifically, in conjunction with schematic diagram shown in Fig. 2, it is equipped with that mirror B is horizontal positioned, and plane is B plane, thereon straight
Line R is North and South direction.It is A that, which there is bracket material object in top, and adjustment A is now required to be allowed to be directed toward magnetic north for accurate south-north direction,
A can rotate adjustment around midpoint in the horizontal plane.A ' is diplopia of the A below mirror, corresponding, when A is rotated around midpoint, A '
Rotation, while generating A ' plane.The light of A ' passes through the eyes that B plane enters people.Using a line E of A as the reference of adjustment
The intersection that line, diplopia E ' and eyes constitute view plane C, C and B is L.Known B planar horizontal is placed, and A plane is tuned into level, therefore
Diplopia plane A ' is parallel with B plane.Due to L and E ' in approximately the same plane C, and two straight lines are respectively in different horizontal planes
It is interior, it is non-intersecting, therefore L is parallel to E ' and is parallel to E.Mobile sight, intersects L with R, angle is the folder of E and magnetic north
Angle adjusts A, keeps diplopia E ' seen in eyes Chong Die with R, and E at this time is parallel to R, is accurately aimed at magnetic north.
In the actual use process, by the mirror image of parallel specular observation steel tower bracket, the direction of steel tower bracket is adjusted
Until observe that the mirror image of bracket is parallel with compass direction in parallel mirror surface, that is, shows the calibration and completion, by reference to
Line can more easily help observer to judge whether the direction of mirror image and compass is consistent.It is understood that in order to keep away
Exempt from interference of the steel tower for compass, in the actual use process, device can be left to steel tower and slightly far seen later
It surveys, in this way it is possible to prevente effectively from steel tower influences the accuracy of compass.
In the present embodiment, be utilized mirror image principle and horizontal mirror surface, by adjusting bracket and make its diplopia
Magnetic north is accurately directed toward in direction, realizes rack alignment magnetic north, and error is can be controlled within 1 °.The present embodiment also avoids
Since compass metal caused by the closer space of steel tower interferes, the accuracy of direction calibration is improved, and then improve
The accuracy of wind transducer measurement data and the credibility of measurement data.In addition, the device is also simple and convenient, it is easy to make
With learning cost is lower.
In one embodiment, reference line 130 is used as when the direction to steel tower bracket is adjusted for observer and adjusts
Standard of the perfect square to reference.
In one embodiment, horizontal mirror surface 110 is circle, is provided with equally distributed graduated scale on horizontal mirror surface 110
Know 140.
In one embodiment, compass 120 is fixedly installed on the center of circle of horizontal mirror surface 110.
In one embodiment, reference line 130 passes through the center of circle of horizontal mirror surface 110, and scale is directed toward in one end of reference line 130
0 °, the opposite other end of reference line 130 is directed toward 180 ° of scale.
In one embodiment, the radius of horizontal mirror surface 110 is 57.3mm.
Accurately to adjust the side E of A and the angle of magnetic north, design mirror B is circle, and compass is fixed at round center,
Circumferential band angle index line.As follows as one of example: mirror radius is 57.3mm with reference to mirror center is passed straight through, directly
One end of line is to be directed toward 0 ° of scale, and the other end is directed toward 180 °, and mirror periphery is carved from the distance between 0-360 ° of groove, every two lines
For 1mm, compass is fixed on mirror center.
Each technical characteristic of above embodiments can be combined arbitrarily, for simplicity of description, not to above-described embodiment
In each technical characteristic it is all possible combination be all described, as long as however, the combination of these technical characteristics be not present lance
Shield all should be considered as described in this specification.
