The invention relates to the technical field of automatic monitoring, and specifically discloses a monitoring device used in an elevator. The device comprises a monitoring part and a dust removing part, wherein the monitoring part comprises a first fixing rack, a camera and a dust guard; a mounting slot in which the camera is mounted is formed in the first fixing rack; the dust guard is rotatablyconnected to the outer circumference of the mounting slot; the dust removing part comprises a second fixing rack, a balancing weight, a transmission mechanism and a dust removing scraper; the balancing weight can vertically slide on the second fixing rack; balancing springs are arranged at the upper end and the lower end of the balancing weight; the transmission mechanism comprises a rack which isfixed to the balancing weight, a first gear which is engaged with the rack, and a first bevel gear which is rotatably connected to the second fixing rack; a second bevel gear which is engaged with the first bevel gear is fixed to the outer circumference of the dust guard; the dust guard can only be rotated in one direction; the first gear and the first bevel gear are connected through an one-waybearing. According to the device, the dust guard rotates relative to the dust removing scraper while the elevator runs, so that the dust on the dust guard can be cleaned.

The invention discloses a 4K ultra-high-definition display spliced screen, which comprises a plurality of shells installed on a wall body and a display screen arranged in front of the shells, throughholes are formed in the centers of the surfaces of the shells, moving plates are arranged in the shells, and more than one spring is installed between the outer ring of each moving plate and the innerwall face of the corresponding shell. The shaft rods are installed at the positions, right opposite to the installation grooves, of the back faces of the display screens, bases are installed at one ends of the shaft rods, one ends of the bases are installed on the movable plate, and adjusting mechanisms for adjusting the distance between the display screens are arranged outside the display screens. The device is simple in structure, the distance between the display screens can be effectively adjusted through the adjusting mechanism, the display screens can be effectively separated during independent display, picture overlapping caused by excessive contact is avoided, the monitoring effect of each display screen is prevented from being affected, the display screens can completely abut against each other, and the display effect is improved, so that a plurality of display screens are spliced into a whole, and the display area is increased.

The invention discloses a monitoring device for urban domestic sewage discharge, which relates to the technical field of sewage discharge. The urban domestic sewage discharge monitoring device includes a fixed cylinder. A fixed ring is fixedly installed on the inner wall of the fixed cylinder near the left end. Mechanism, the inside of the fixed cylinder near the right end is fixed with a monitoring piece through a fixed column, the filter mechanism includes an elastic ring, an annular cavity, an elastic filter piece and a movable part, and the elastic ring is fixedly installed on the left side of the fixed ring , the outer surface of the elastic ring is in contact with the inner wall of the fixing cylinder.
