A kind of anemometer support that can be fixed on the cable

Abstract

The invention discloses an anemometer bracket that can be fixed on a cable, comprising a fixing device, a bracket component connected with the fixing device, a position testing component and an acceleration testing component, the fixing device includes a hoop surrounded by a flexible metal sheet, A grid-like magnet embedded in the inner surface of the metal sheet, and high-strength bolts for fixing the metal sheet; the bracket assembly includes an outrigger, an anemometer support, and a nut that is threaded at the end of the outrigger; the position test assembly It includes a position sensor; the acceleration test assembly includes a three-way acceleration sensor, and the present invention can be fixed at any position on the cable, and can ensure that the anemometer is vertical for any inclined cable with the horizontal plane, and it is easy to control the position of the measuring point , it is convenient to remove the influence of the cable vibration and at the same time obtain the relationship between the wind speed at the measuring point and the vibration of the cable, which can better test the distribution characteristics of the wind field around the cable.

Description

technical field [0001] The invention relates to an anemometer bracket that can be fixed on a cable, and is especially suitable for testing the wind field around a long cable in a long-span cable-supported bridge system, and is mainly used in the field of civil structure wind engineering. Background technique [0002] With the rapid development of design methods and construction technology in the field of civil engineering, the number and scale of long-span cable-supported bridges continue to increase, and the flexibility of the corresponding structures shows an increasing trend, and wind load is the main force of most long-span, high-flexibility structures. controlled load. Especially in the southeast of my country, where rivers are densely covered, the economy is developed, and the population is densely populated. A large number of large-scale and significant long-span cable-supported bridge structures have been built. For example, the cable-stayed bridge with the largest s...

AI Technical Summary

Problems solved by technology

Considering the wide range of cable distribution and the random distribution of wind characteristics, the accuracy of the results obtained by traditional methods is poor and the reliability is not high, which seriously restricts the related research work on cable wind vibration.
