Description

Local ventilator for urban rail transit overhead station Technical Field The utility model relates to the technical field of ventilators, in particular to a local ventilator for an overhead station of urban rail transit. Background The overhead station is like the stand of bus, needs to arrange along the website, and the overhead station needs to provide a comfortable, convenient, safe environment of waiting for the passenger, in order to keep the inside circulation of air of overhead station, not only need set up ventilation system at overhead station top, still need ventilators that set up at the top to ventilate. Traditional ventilator is when using, in the in-process of extraction air, filters the back and outwards discharges again to the air, but traditional ventilator filter core often sets up in the inner chamber of ventilator, need change the filter core after the filter core uses a period, and traditional ventilator is when changing the filter core, need unpack equipment, just can change the maintenance to the filter core, and traditional equipment can't detect the service condition of filter core, can't discover in time that the filter core appears blockking up to can't timely change the filter core. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the local ventilator for the overhead station of the urban rail transit, which has the advantages of convenient replacement of the filter element and detection of the use state of the filter element, and solves the problems proposed by the background art. The utility model provides a local ventilator for an overhead station of urban rail transit, which comprises an air inlet cylinder, wherein a filter box is arranged at the top of the air inlet cylinder, an air outlet cylinder is fixedly arranged on the outer wall of the filter box, an installation plate is fixedly arranged in an inner cavity of the air inlet cylinder, a driving motor is fixedly arranged in an inner cavity of the installation plate, a fan blade is fixedly arranged on a power output shaft of the driving motor, a mounting frame is movably sleeved in the inner cavity of the filter box, a filter element is arranged in the inner cavity of the mounting frame, a rotating plate is rotatably connected to the outer wall of the filter box, a pull rod is movably sleeved in the inner cavity of the rotating plate, a pressing plate is fixedly arranged on the outer wall of the pull rod, a driving spring is movably sleeved on the outer wall of the filter box, a control screen is fixedly arranged on the outer wall of the filter box, an impeller is rotatably connected to the inner cavity of the air outlet cylinder, a permanent magnet block is fixedly arranged on the outer wall of the impeller, and a Hall element is fixedly arranged in the inner cavity of the air outlet cylinder.
