A mobile test device applied to wind tunnel test of terrain model wind field characteristics

Abstract

The invention discloses a mobile testing device applied to wind tunnel tests of terrain model wind field characteristics. The mobile test device includes a test support system, a support fixing system and a support turntable system; the test support system includes a longitudinally arranged outrigger and a plurality of vertically arranged support booms mounted on the outrigger, the support The boom is equipped with a probe bracket that can rotate around the bracket boom and move vertically along the length of the bracket boom; The support column on the ground; the support turntable system itself is rotatable, and can move longitudinally along the length direction of the outrigger, and can also move laterally along the length direction of the support beam. The test device of the present invention can continuously adjust the wind speed test instruments such as test probes in the horizontal plane and the vertical plane, and can accurately measure the wind field characteristics of each point on the terrain model.

Description

technical field [0001] The invention relates to a testing device in a wind tunnel test of a terrain model wind field characteristic, in particular to a multi-measuring point, large-scale and large-scale complex terrain model wind field characteristic test. Background technique [0002] To build a bridge in a mountainous area with complex terrain, it is necessary to obtain the wind characteristic parameters such as the average wind speed and fluctuating wind speed in the bridge site area through the wind tunnel test of the bridge site area model, so as to provide a scientific basis for the wind resistance design and construction of the bridge. In addition, when selecting wind farm macro and micro sites in complex mountainous terrain, it is also necessary to clarify the wind field characteristic parameters at the wind farm site, so as to provide guarantee for the efficient and safe operation of wind turbines. At present, there are mainly two devices for measuring wind speed in...

AI Technical Summary

Problems solved by technology

The inherent probe of the wind tunnel cannot be moved, which cannot be used in the wind tunnel test of the wind field characteristics of the complex terrain model, and the device carrying the probe on the seat bracket is difficult to fix on complex terrain, and it is easy to topple under the strong incoming wind. It is also unable to complete the wind tunnel test requirements for the wind field characteristics of the complex terrain model

[0003] At present, there is no special wind speed test device for the wind tunnel test of the wind field characteristics of the complex terrain model, and most of the devices used in the test are the improvement of the old device or simple reprocessing on this basis

Due to the lack of targeted design and demonstration, the efficiency of these improved devices is low during the test, and the reliability of the test data and the continuity of the use of the device cannot be guaranteed
