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 transmission iron tower detection, in particular to a wind force measurement device for a transmission iron tower model and a measurement method thereof. Background technique [0002] In recent years, the problem of power transmission towers being affected by typhoons has attracted everyone's attention. Tower collapse accidents caused by typhoons in coastal areas have occurred frequently, seriously affecting the stable operation of the power grid. Therefore, it is imminent to carry out research on wind resistance design and wind disaster prevention measures of transmission towers, improve the safety of transmission towers in strong wind 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 simula...
