Abstract

The invention discloses an anemograph support capable of being fixed on an inhaul cable. The support comprises a fixing device, a support assembly connected with the fixing device, a position testingassembly and an acceleration testing assembly, the fixing device comprises a hoop enclosed by a flexible metal sheet, a latticed magnet embedded on the inner surface of the metal sheet and a high-strength bolt for fixing the metal sheet; the support assembly comprises an outwards-extending rod, an anemograph support and a nut matching the end of the outwards-extending rod in a threaded mode; the position testing assembly comprises a position sensor; the acceleration testing assembly comprises a three-way acceleration sensor. The support can be fixed to any position of the inhaul cable, which can guarantee that an anemograph is vertical for the stay cable forming any angle with the horizontal plane; the position of a measuring point is easy to control, the relation between the wind speed ofthe measuring point and inhaul cable vibration is obtained while the influence of inhaul cable vibration is conveniently removed, and the wind field distribution characteristic around the inhaul cable can be better tested.

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...
