The invention relates to the technical field of metro platform screen
doors, in particular to a novel particulate matter-preventing energy-saving metro platform screen door with an adjustable
tuyere, which comprises a metro platform, and a plurality of left-side perforated platform screen
doors and right-side perforated platform screen
doors are fixedly mounted on two sides of the metro platform respectively; a rotating mechanism is movably connected to one side of each shielding door with holes in the left side and one side of each shielding door with holes in the right side, an
automatic control system is fixedly connected to one side of one shielding door with holes in the left side, and a left tunnel and a right tunnel are correspondingly arranged on one side of each shielding door with holes in the left side and one side of each shielding door with holes in the right side. The
automatic control system adjusts the angle of the rotary baffle and closes the holes in the shielding doors on the two sides through a
control circuit, on one hand, the filter screen can filter out coarse particles, on the other hand, the shielding doors can block fine particles such as PM2.5, and therefore dispersion of the particles in the tunnel into the platform is reduced, and in summer, due to the fact that the holes of the shielding doors are closed, the shielding doors can not be blocked. The loss of
cold air in the platform into the tunnel is reduced, and energy is saved.
