2) the method comprises the following steps that a corner clamp is arranged on each of two stand columns at a certain height of the anemometer tower, and the two corner clamps are measured by a level ruler and are locked by bolts after the two corner clamps are completely horizontal; the corner clamp is formed by combining a transverse clamp and a vertical clamp and is fixed into a whole;
3) the cross rod of the L-shaped support is plugged into the corner hoop, the bolt tightly clamping the cross rod on the corner hoop is slightly fastened, then the auxiliary alignment device is tightly attached to the anemometer tower to move upwards, specifically, the clamping position of the auxiliary alignment device is clamped on the vertical rod, the transverse rod is tightly attached to the anemometer tower to move upwards, so that the verticality of the vertical rod of the L-shaped support is corrected, and then the bolt of the corner hoop is locked;
4) after the installation is finished, the horizontal ruler and the auxiliary alignment device are taken down;
when the sensor on the montant needs to be maintained, need loosen the bolt of chucking horizontal pole on the corner clamp earlier a little, then move the horizontal pole towards surveying wind tower direction, lock the bolt of corner clamp again, maintain the back that finishes, loosen the bolt of corner clamp, release the horizontal pole and reset the back, lock the bolt of corner clamp again.
Further, the cross bar, the vertical bar and the auxiliary aligning device are aluminum alloy pieces.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. the aluminum alloy pipe is adopted to replace an iron pipe, so that the weight is light, the transportation and the installation are very convenient, and the service life is long.
2. The mode that a single straight rod is adopted for transportation and is assembled into an L shape on site is adopted to replace a L-shaped integrated support, so that the L shape of the support is ensured to have very good verticality, and the transportation cost is low.
3. The mode of installing the corner clamp earlier is adopted, ensures that two corner clamps are in complete level back on the anemometry tower body, fills in the horizontal pole of support, ensures that the horizontal pole of support is in complete horizontality.
4. An auxiliary alignment device is used as a tool to ensure that the vertical rod of the L-shaped support is in a vertical state.
5. The mode that the support is completely lapped on one surface of the anemometer tower (instead of a stand column) is adopted, so that the support is ensured not to swing under the action of strong wind.
6. When the sensor needs to be maintained, the sensor can be maintained by moving the sensor to the position near the tower body of the anemometer tower from 2.5m by loosening the two corner clamps of the fixed cross rod and moving the bracket without being hung on the ground, so that time and labor are saved.
