Problems solved by technology

The fixed connection method is to directly fix the damping net on the cylinder of the stable section. There are problems such as the tension of the damping net cannot be adjusted, and it is inconvenient to disassemble and assemble during operation and maintenance. The elastic connection needs to open holes on the cylinder. Many, there are problems such as cylinder sealing

Abstract

The invention provides a fastening device for a damping net at a stilling chamber of a wind tunnel. The fastening device comprises a fixing rack, a tensioning mechanism and a clamping device. The fixing rack is directly welded to a cylinder of the stilling chamber of the wind tunnel. One end of the tensioning mechanism is mounted on the fixing rack; the other end of the tensioning mechanism is connected with the clamping device. The damping net is wound around a wire rope and locked; the wire rope with the damping net is fastened to the clamping device. The fastening device allows tension level of the damping net to be adjustable, axial speed of air after passing the damping net is evenly distributed, the fastening device is simple and reliable in structure and easy to demount and mount, perforating the cylinder is not required, and sealing problems are avoided.

Description

technical field [0001] The invention relates to a damping net fixing device for a wind tunnel stabilization section. Background technique [0002] In order to improve the quality of the flow field in the wind tunnel test section, several layers of damping nets need to be installed in the stable section. The existing fixation of the damping net in the stabilizing section of the wind tunnel mainly includes a fixed device and an elastic connection device. The fixed connection method is to directly fix the damping net on the cylinder of the stable section. There are problems such as the tension of the damping net cannot be adjusted, and it is inconvenient to disassemble and assemble during operation and maintenance. The elastic connection needs to open holes on the cylinder. Many, there are problems such as cylinder sealing. Contents of the invention [0003] Based on the above technical problems and difficulties, the present invention provides a fixing device for the dampin...
