Abstract

The invention discloses a manual type air pipe air direction and air speed adjusting device which comprises a horizontal base, universal wheels, a vertical sleeve arranged on the horizontal base, an inner adjusting rod sleeved with the vertical sleeve in a threaded manner and a horizontal installation board installed on the inner adjusting rod. A transverse groove for installation of a horizontal sliding rail is formed in the upper portion of the horizontal installation board. A left installation seat and a right installation seat are installed on the horizontal installation board. Two laterally-moving sliding blocks are arranged on the horizontal sliding rail. A left push-pull rod is arranged on the left installation seat and a right push-pull rod is arranged on the right installation seat. A left strut is arranged on the left sliding block and provided with a left clamping board, and a left guide board is arranged on the front side of the left clamping board. A right strut is arranged on the right sliding block and provided with a right clamping board, and a right guide board is arranged on the rear side of the right clamping board. The manual type air pipe air direction and air speed adjusting device is simple in structure, reasonable in design, convenient to use and operate, good in use effect and capable of easily and conveniently adjusting the air supply direction and the air speed of any position of an air pipe.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to a manual air duct wind direction and wind speed adjustment 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. [0003] 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...
