Problems solved by technology
[0004] It can be seen from the above that there is a lack of an automatic adjustment device for the wind speed and direction of the flexible air duct with simple structure, reasonable design, easy processing, easy operation, and good use effect, which can adjust the size and opening of the flexible air duct. The orientation adjusts the wind speed and direction to quickly and effectively improve the air conditions near the face of the tunnel

The invention discloses an automatic air speed and air direction adjusting device for a flexible air pipe. The automatic air speed and air direction adjusting device comprises a base, an electric lifting rod, a walking wheel, an electric rotary seat, a horizontal platen installed on the electric rotary seat, a first hinging seat installed on the horizontal platen, two arc-shaped adjusting frames installed on the left side and the right side of the first hinging seat and two clamping boards installed above the outer ends of the two arc-shaped adjusting frames. The inner ends of the two arc-shaped adjusting frames are installed on the first hinging seat in a hinged manner. The two arc-shaped adjusting frames are located on the front side and the rear side of the first hinging seat. The inner side walls of the two clamping boards are provided with anti-skid layers. Two hydraulic oil cylinders for supporting the two arc-shaped adjusting frames are arranged on the horizontal platen. An electronic circuit board is arranged in the horizontal platen. The automatic air speed and air direction adjusting device is simple in structure, reasonable in design, easy and convenient to machine, manufacture, use and operate, good in use effect and capable of adjusting the air speed and the air direction through adjustment of the size and the direction of a pipe opening of the flexible air pipe.
Description
technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to an automatic adjustment device for wind speed and wind direction of a flexible air duct. 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, after the blasting is completed, the concentration of blast smoke and harmful gases produced by blasting and transportation in the cave is relatively large. Next, adjust t...
