Cleaning device and system for video surveillance camera for tunnel under construction

Abstract

The invention provides a cleaning device and system for a video surveillance camera for a tunnel under construction. The cleaning device comprises a film rolling unit and a film driving unit, whereinthe film rolling unit comprises a first reel, a second reel, and a transparent film, the first reel and the second reel can be rotatably mounted on the opposite sides of the video monitoring camera, one end of the transparent film is wound around the first reel and the other end of the transparent film covers a lens of the video monitoring camera and is wound around the second reel; the film driving unit is connected with the first reel and the second reel and is used for receiving a lens cleaning instruction and controlling a film rolling unit to move according to the lens cleaning instruction, so that the first reel rotates a clean transparent film to the front of the lens, and the second reel rolls a dirty transparent film away. A user can remotely control the cleaning device to roll the transparent film before the video monitoring camera for the tunnel under construction, so that the lens can be kept clean, thereby ensuring clear shooting of a security monitoring screen.

Description

technical field [0001] The invention relates to the field of tunnel security and rescue equipment, in particular to a cleaning device and system for video surveillance cameras used in tunnels under construction. Background technique [0002] Although the modern means of expressway construction are improving more and more, the construction environment of expressway tunnels is still harsh and harsh. The work in the tunnel excavation area requires real-time monitoring of the construction progress and the security of the personnel's work status, especially on the "drill face" that is most prone to collapse. There are a large number of workers in this area, and there are major , Extraordinary collapse safety accidents, video monitoring of personnel and vehicles in this area is very necessary. [0003] In the tunnel under construction, the working environment of the lens of the security video surveillance camera is special and harsh compared to the conventional camera: quick-dryi...
