Embodiment Construction

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0027] The problem to be solved in the embodiments of the present invention is that the width of the wedge in the prior art is difficult to change after it is manufactured, and local adjustment cannot be realized, and it can only be assisted by other auxiliary devices. This scheme will cause the problems of long test cycle and low test precision. In addition, the finished wedge can only satisfy the simulation of the wind speed profile under a single scale ratio. If the test is carried out under multiple scale ratios, it is necessary to make a wedge separately, which will increase the test cost.

[0028] Such as Figure 1-3 As shown, it is a schematic diagram of a passive simulation wedge device for adjustable wind ...

Abstract

The invention relates to a passive simulation wedge device with adjustable wind profile for a building wind tunnel, belonging to the technical field of building wind tunnel tests. It includes: the base, which is installed on the bottom surface of the wind tunnel; the wedge body, the bottom of the wedge body is fixedly connected with the base; the wedge body includes a middle plate and a wing plate, and one side of the middle plate is fixedly connected to one side of the wing plate, so that the wing The board is divided into the first wing and the second wing; the width adjustment parts are respectively installed along the first wing and the second wing, and the sharpness is realized by controlling the installation positions of the width adjustment parts on the first wing and the second wing. Width adjustment of the wedge device; a fixing piece, the fixing piece is fixedly connected with the top of the wedge body, and is used to fix the wedge body in the wind tunnel. The invention can meet the flexible adjustment of the target wind speed profile in the wind tunnel test process, and the process is fast, and the wind speed profile simulation accuracy is high, and the wedge device of the invention has simple structure, easy assembly, wide applicability and low production cost.

Description

technical field [0001] The invention belongs to the technical field of building wind tunnel tests, in particular to a passive simulation wedge device with adjustable wind profile for building wind tunnels. Background technique [0002] In the building wind tunnel test, it is necessary to simulate the wind speed profile of different landforms, and the method commonly used today is the passive simulation method. Usually, the passive simulation method uses different blocking devices to block the incoming flow inside the building wind tunnel, so that the wind speed presents the required distribution in the vertical direction (that is, the wind speed profile, also known as the wind profile). Blocking devices mainly include wedges and rough elements. The wedge stands in the upwind direction, and the upper and lower widths are different, causing different obstructions to the air and making the upper and lower wind speeds different. [0003] At present, the general practice is to ...
