Abstract
The invention relates to a protection device for a high-altitude sensor. The high-altitude sensor is arranged on a steel wire rope between a pole tower and a support tower. The steel wire rope is connected with a tension hydraulic cylinder. The protection device comprises a V-shaped anti-torsion assembly at the two ends of the high-altitude sensor. The high-altitude sensor is in the form of a tension sensor connected with an information analysis processor. The V-shaped anti-torsion assembly is provided with an anti-falling assembly connected with the two ends of the V-shaped anti-torsion assembly. By means of the protection device for the high-altitude sensor, no torsional force is applied onto the high-altitude sensor during the tension resistance testing process of the pole tower, so that the high-altitude sensor is prevented from rotating or even flying away from the pole tower. Therefore, the production cost is lowered, and the torsion resistance is improved. Meanwhile, the test working efficiency is improved.
