Description
Technical field: the utility model relates to a kind of counter-rotating main fan automatic control changeover apparatus.
Background technology: at present, existing mine main fan is, two Fans exposed layout in parallel on the ground, share a wind cave, by the outlet of a Y type wind cave fork, with two Fans wind collecting units, be connected, install before wind collecting unit when Motorized Operated Damper is used for switching blower fan and open, the use of closing, such connected mode, increased flowing resistance owing to having increased a flex point simultaneously, about 20-30mm water column, extremely frigid zones ventilation fan winter operation existing problems are, during the ventilation fan operation, in the warm-humid air suction blower fan of down-hole with the cool exterior air a part of condensed water of rear formation that meets, 24 hours uninterrupted current blowing machine diffuser bottom discharge mouths, form gradually icicle, cumulative larger, only take the way of artificial water ice to process at any time, the mine also had adopts electrically heated way to prevent from freezing, water is caused to several meters outer discharges of blower fan number, but also causing is ice everywhere, hinder normal operation, the situation that air door is frozen in especially often occurs, when normally switching blower fan or switching blower fan because of accident, only take the various spot heating ways rear blower fan that just can complete that thaws to switch, freezing when serious the blower fan switching time surpass regulation and complete within 10 minutes and switch, very easily cause potential safety hazard and accident.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of counter-rotating main fan automatic control changeover apparatus is provided, it has mainly solved existing mine with the main fan two Fans exposed ground that are arranged in parallel, share a wind cave, ventilation fan when operation, in the warm-humid air suction blower fan of down-hole with the cool exterior air problems such as a part of condensed water of rear formation of meeting.The purpose of this utility model is achieved in that counter-rotating main fan automatic control changeover apparatus consists of: wind collecting unit, spring, electromagnet, loose flange, counter-rotating fan, noise elimination diffusion barrel, noise elimination retention tower, base, supporting leg, rail bed, mobile flat car, ventilating shaft outlet, locking device, limit switch, car bumper, track, winch, wire rope, changed course rope sheave.Two counter-rotating fans are installed in parallel on mobile flat car, the outlet of noise elimination diffusion barrel and counter-rotating fan connects, the noise elimination diffusion barrel is connected with the noise elimination retention tower, noise elimination diffusion barrel and noise elimination retention tower are fixed on base by supporting leg, loose flange one end is connected with wind collecting unit, the other end is connected with counter-rotating fan, spring and electromagnet are housed on loose flange, the ventilating shaft outlet is connected with wind collecting unit, mobile flat car is installed in orbit, limit switch and car bumper are housed on track, track is arranged on rail bed, between mobile flat car and track, locking device is housed, wire rope is connected with mobile flat car by the changed course rope sheave, wirerope-winding is on winch.This product structure is simple, reasonable in design, it has realized that the convection rotary type ventilation fan switches fast, automatic operation, the loose flange of wind cave docks by the magnetic means automatic-sealed with blower fan wind collecting unit flange, blower fan direct ventilation cave, the wind cave is without fork, reduce flowing resistance 20-30mm water column, improved fan operation efficiency, blower fan is fixedly mounted in Ventilator Room, the wind cave is interior without air door, two ventilation fans share a wind diffusion tower, there is no the cold-hot wind exchange, solve the blower fan freezed in winter and frozen the hidden danger such as air door, the devices such as a set of main fan noise elimination diffusion barrel and noise elimination retention tower have been reduced, reduced cost of production.
