Furthermore, the compass and the mirror reflector are horizontally aligned, and the south-north line is arranged on the extension line of the south-north or north-south scale mark of the compass. During the check-up, the levelness of adjustment assembly box for the north-south line coincides or is parallel with the projection that the wind xarm of wind pole projects mirror surface reflector, then observes compass and points to whether with the coincidence of north-south line, can audio-visually judge that the wind direction sensor of wind pole indicates the north correctly.
Further, the compass is provided with a 360 ° dial, the minimum unit of which is 3 °. The wind direction sensor deviation angle of the wind rod can be conveniently observed through the dial, and calibration is convenient.
Further, the bottom of the assembly box is provided with a plurality of adjusting bolts for adjusting the levelness of the upper surface of the assembly box. Can adjust the levelness of assembling the box through adjusting bolt for north-seeking check gauge can both keep the upper surface level at level ground and unsmooth ground, and the check-up result is accurate.
Furthermore, the compass, the mirror reflector and the level meter are all horizontally arranged.
Further, the assembly box includes that one is the box of cuboid, compass, specular reflection mirror and spirit level are all located the upper surface of box.
Further, the specular reflection mirror is a plane mirror.
Due to the adoption of the technical scheme, the beneficial effects of the utility model are that:
when the north-seeking check meter of the utility model is used, the north-seeking check meter is firstly placed on the flat ground around the wind pole to be checked, then the north-seeking check meter is rotated to enable the wind cross arm of the wind pole to be projected onto the mirror reflector, and the projection of the wind cross arm of the wind pole on the mirror reflector is coincided with or parallel to the north-south line; if the compass is just positioned in the true south or the true north scale, the wind direction is correct to point to the north; if the compass deviates from the true south or north scale, the wind direction deviates from the north, and the deviation angle of the compass is the deviation of the wind direction from the north. The utility model discloses a north-seeking check gauge convenient to use can carry out the check-up in any position all around of wind pole, and quick wind direction sensor to the wind pole carries out the north-seeking check-up to conveniently shoot and stay the trace and keep, file, moreover the utility model discloses a north-seeking check-up gauge still can be used to equipment fixing guide calibration such as sunshine sensor, radiation sensor, visibility sensor, precipitation weather phenomenon appearance.
