Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, and in particular to a tunnel safety monitoring device. Background Art

[0002] Monitoring devices are usually composed of components such as cameras, lenses, pan / tilt heads, protective covers, listeners, alarm detectors and multi-function decoders. They each have their own functions and establish corresponding connections with various equipment in the central control system through wired, wireless or optical fiber transmission media.

[0003] In order to ensure the safety of tunnels, monitoring devices are often installed inside tunnels. Although the existing monitoring devices can realize basic monitoring functions during actual use, they generally do not have the function of cleaning the protective windows. If a large amount of dust is adsorbed on the surface of the protective windows, the protective windows need to be cleaned manually. However, the manual cleaning method cannot clean the protective windows in time, which leads to a long cleaning time, affecting the normal use of the monitoring device during the period when the protective windows are not cleaned. Therefore, it is necessary to improve it. Utility Model Content
