Problems solved by technology

However, the wind speed pipes used in conventional atmospheric boundary layer wind tunnels in the past only collected total pressure and static pressure, and did not consider the three-dimensional effect of the wind field. angle difference
In addition, the height above the ground of each probe is fixed. When it is necessary to encrypt the measuring point for a certain height range at the specified spatial position, real-time adjustment of the height of the measuring point cannot be realized.
Therefore, the existing measurement devices and methods cannot meet the actual needs

Abstract

The invention discloses a portable device for measuring the three-dimensional wind speed of a wind field, and a manufacturing and application method of the portable device. The device comprises an I-shaped support which consists of an upper end face, a lower end face, and a central part. The central part of the I-shaped support is a streamline shaped housing, and the upper and lower end faces of the I-shaped support are respectively provided with a cover plate. The cover plates are fixed with the streamline shaped housing in a sealed manner, and the interior of the streamline shaped housing is fixedly provided with a clamping groove. The interior of the clamping groove is provided with a probe installation plate, and the probe installation plate is in fixed clamping connection with a clamping groove. The device also comprises a housing installation plate, and the upper part of the housing installation plate is closely provided with a level plate which is hinged to one end of the housing installation plate. The probe installation plate is provided with scale and a plurality of probe installation holes, and positioning grooves are respectively disposed above each probe installation hole. The device is simple in manufacture, is convenient to install, is wide in application range, is low in construction cost, and can achieve the quick measurement of the three-speed wind speed of wind speeds, such as complex mountains and valleys, and downburst.

Description

technical field [0001] The invention relates to a test device in the technical field of structural wind engineering, in particular to a convenient device for measuring three-dimensional wind speed in a wind field and a method for manufacturing and using it. Background technique [0002] In recent years, wind disaster accidents of various structural systems have occurred frequently, among which the safety problem of transmission tower line system is particularly prominent. On the one hand, this is due to its own structural characteristics, such as long line corridors, high probability of passing through areas with high incidence of severe weather and complex terrain, strong structural flexibility, and strong vibrations under the action of natural wind; On the other hand, due to insufficient consideration of the micro-topographic wind field and the unhealthy wind field represented by the downburst flow (including squall line wind) during the design, they are collectively refer...
