The invention provides a large draught fan convenient to install and used for a tunnel. The large draught fan convenient to install and used for the tunnel comprises a draught fan shell, fan blades, a motor, a rotating shaft, a ventilating pipe, a ground fixing device, a flange plate, a hoisting device and a dustproof net; the draught fan shell is communicated with the communicating pipe through the flange plate; and the fan blades are inserted and connected in the rotating shaft. Due to the arrangement of the dustproof net of the large draught fan convenient to install and used for the tunnel, it is easily prevented that dust and other sundries enter the ventilating pipe to damage the draught fan; due to the arrangement of an adjusting bolt, a fixing bolt and a through hole, it is facilitated that a fixing base is fixed to the ground conveniently, the fixing base can be firmer, and the height of the draught fan can be conveniently adjusted; due to the arrangement of an installing hole, a fastening bolt, an installing base, a connecting pipe and a fastening base, it is facilitated that the draught fan can be hoisted on the top of the tunnel, and a proper installing manner can be conveniently selected; and due to the arrangement of a fixing hoop, an adjusting button, a telescopic hoop and a clamping hoop, it is facilitated that a proper radian is selected according to the radian of the ventilating pipe so that the ventilating pipe can be hoisted.
Description
technical field [0001] The invention belongs to the technical field of tunnel ventilation equipment, and in particular relates to a large fan for tunnels which is easy to install. Background technique [0002] Tunnel fans are widely used in the actual use of water conservancy dam projects, highways, railways, subways and other tunnels. In the long-term use of the tunnel fan, due to the large amount of dust in the environment, the impeller is easy to wear and accumulate dust. In severe cases, the fan will run unbalanced and vibrate greatly, which will cause damage to the fan impeller and cause failure. [0003] The Chinese patent application number is 201620343533.4, and the name of the invention is a tunnel fan, which includes a motor, an impeller and a muffler. The impeller is connected to the shaft of the motor. , the inside of the dust cover is provided with a corona wire, the corona wire is a wire mesh, there is a distance between the corona wire and the dust cover, and...
