Automatic following wind direction regulation device for orifice of flexible air duct

Abstract

The invention discloses an automatic following wind direction regulation device for an orifice of a flexible air duct. The device comprises an air duct orifice wind direction regulator and an air condition detection device which is in front of the air duct orifice wind direction regulator and detects air conditions on a tunnel face of a constructed tunnel in real time. The air condition detection device comprises a detection frame, a plurality of air condition detection units respectively arranged in a plurality of monitoring regions of the tunnel face, and a comparison controller connected with the air condition detection units. The air duct orifice wind direction regulator comprises a horizontal base, a standing cabinet, a rotating shaft, a horizontal hinge joint base fixed on the upper part of the rotating shaft, a self-adsorbing clamping mechanism which is above the horizontal hinge joint base and clamps the orifice of the flexible air duct, and a manual open-close mechanism which opens and closes the self-adsorbing clamping mechanism. The device is simple in structure, rational in design, simple in processing and manufacturing and use and operation, and good in use effect, and can simply adjust wind supply directions of the orifice of the flexible air duct.

Description

technical field [0001] The invention relates to a wind direction control device, in particular to an automatic following type flexible air duct nozzle wind direction control device. Background technique [0002] At present, the tunnel construction ventilation at home and abroad mostly adopts the pipeline press-in ventilation method, and an axial flow fan is installed outside the tunnel entrance. The fresh air is sent to the tunnel excavation face, and the dirty air in the tunnel is expelled out of the tunnel along the excavated tunnel body under the squeeze of the fresh air sent into the tunnel. When the tunnel is long, multiple axial flow fans are used in parallel and in series to increase the air volume and air supply distance. In the actual construction process, once the flexible air duct in the tunnel is installed, its position will not be easily moved, and the flexible air duct is usually arranged in the middle and upper part of the side wall of the tunnel, so that the...
