Monitoring device for elevators

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automatic monitoring, in particular to a monitoring device used in an elevator. Background technique [0002] The monitoring system is one of the most widely used systems in the security system. The most suitable construction site monitoring system on the market is a handheld video communication device, and video monitoring is now the mainstream. When the video surveillance system is working, if the camera is covered by dust, it will not be possible to obtain clear video recordings. In the existing video surveillance system, cameras are located in every corner of the building, including aisles, corners, outdoors and elevators. In some corners of the building, there is a large flow of people, so there is more dust raised during the walking process. In order to To ensure that the implementation obtains a clear monitoring picture, it is often necessary to regularly clean the dust attached to the camera. Du...

AI Technical Summary

Problems solved by technology

The elevator is a relatively closed small space, so the monitoring of the elevator is essential, and the traffic flow of elevators in different locations is also different. The more people in the elevator, the easier it is for dust to adhere to the camera, and the greater the traffic Elevators are also the key monitoring objects, so the cleaning frequency of the camera is higher for elevators with more traffic, while for elevators with less traffic, the cleaning frequency is low

Since the cleaning time of the cameras of different elevators is different, it is not convenient to manage the cameras
