Self-adjusting device for air supply direction of air pipe

Abstract

The invention discloses a self-adjusting device for the air supply direction of an air pipe. The self-adjusting device comprises a horizontal base, a traveling mechanism mounted at the bottom of the horizontal base, a traveling driving motor, a vertical sleeve mounted on the horizontal base, an inner supporting rod coaxially inserted into the vertical sleeve, an electric rotary seat arranged on the upper portion of the inner supporting rod in a sleeving mode, a horizontal supporting plate disposed on the electric rotary seat, a left air direction adjusting mechanism mounted on the upper portion of the left side of the horizontal supporting plate, a right air direction adjusting mechanism mounted on the upper portion of the right side of the horizontal supporting plate and an air direction adjusting state detecting unit which detects the air direction adjusting state of the adjusted flexible air pipe in real time. The horizontal supporting plate is provided with a height detecting unit. A control box is mounted on the vertical sleeve. The self-adjusting device for the air supply direction of the air pipe is simple in structure, reasonable in design, low in input cost, easy and convenient to use and operate, good in using effect and capable of freely moving in a tunnel and easily and conveniently adjusting the air supply direction of the air pipe in any position in the tunnel.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to a device for self-adjusting the air supply direction of an 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 the wind speed at the...

AI Technical Summary

Problems solved by technology

Nowadays, the number of straight tunnels is very small, especially for long-distance tunnels. There are many places in the tunnel that need to adjust the wind direction of the flexible air duct. Affects air volume and wind speed

Therefore, there is currently a lack of a flexible air duct air supply direction adjustment device with simple structure, reasonable design, low input cost, easy operation, and good use effect, which can move freely in the tunnel hole and can control any air flow in the tunnel hole. The air supply direction of the air duct at one position can be easily adjusted without affecting the air supply volume and air speed of the air duct
