Abstract

The present invention relates to a transmission tower model wind power measurement device and a measurement method thereof. The wind power measurement device comprises a transmission tower model measurement cylinder, a strain gauge pasted on the wall of the measurement cylinder and a strain analyzer connected with the strain gauge; when measurement, the measurement cylinder is vertically arranged to allow one end of the measurement cylinder to face upwards, the transmission tower model is arranged on this end, the strain analyzer collects strain value data of the strain gauge, and the size of wind power of the model is obtained according to the corresponding relation of model force and the strain value of the strain gauge and the change of the strain value of the strain gauge before and after application of wind power. The transmission tower model wind power measurement device and the measurement method thereof measure the strain gauge on the measurement cylinder to measure the wind power of the transmission tower model, and the size of the measurement cylinder can be designed according to the concrete shape of the transmission tower model, so that the transmission tower model wind power measurement device and the measurement method thereof are suitable for large-volume, heavy and complex transmission tower model wind power measurement and are simple in measurement process and easy to realize.

Description

Technical field [0001] The invention relates to the technical field of power transmission tower detection, in particular to a wind power measurement equipment of a power transmission tower model and a measurement method thereof. Background technique [0002] In recent years, the problem of typhoon impacts on transmission towers has attracted attention. The frequent occurrence of tower collapse accidents in coastal areas caused by typhoons has seriously affected the stable operation of the power grid. Therefore, it is urgent to carry out research on the wind-resistant design of transmission towers and wind disaster prevention measures, improve the safety of transmission towers under strong wind and disaster weather, reduce the occurrence of transmission tower collapse accidents, and ensure the reliability of power supply. [0003] At present, in practical engineering applications such as buildings, structures, and bridges, wind tunnel tests are usually used to simulate wind flow fie...
