Mobile test device for terrain model wind field characteristic wind tunnel experiment

Abstract

The invention discloses a mobile test device for a terrain model wind field characteristic wind tunnel experiment. The mobile test device for the terrain model wind field characteristic wind tunnel experiment comprises a test support system, a support fixing system and a support rotary disc system, wherein the test support system comprises a protruding support which is vertically arranged and a plurality of support hanging rods vertically arranged and installed on the protruding support, probe supports which can rotate around the support hanging rods and vertically move along the length direction of the support hanging rods are installed on the support handing rods, the support fixing system comprises a support beam transversely arranged and a plurality of support stand pillars installed on the support beam and supported on the ground, and the support rotary disc system can automatically rotate, can vertically move along the length direction of the protruding support, and further can transversely move along the length direction of the support beam. The mobile test device for the terrain model wind field characteristic wind tunnel experiment enables a person to continuously adjust wind speed testers of test probes and the like in a horizontal plane and a vertical plane, and can accurately measure wind field characteristics of all points on a 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
