Description

Technical Field

[0001] This utility model relates to the field of risk monitoring and alarm equipment technology, and in particular to a navigation risk monitoring and alarm device for ships in navigable tunnels. Background Technology

[0002] Ship tunnels are an important new type of vessel passage facility in the development of high-head cascade waterway channels in high mountain canyons and rivers, but mature experience is lacking worldwide. Their semi-enclosed, shallow, and narrow characteristics present new challenges to ship navigation safety, making emergency response to accidents within the tunnels difficult and requiring extremely high levels of risk control. Ship tunnels are one type of transportation tunnel.

[0003] Currently, there are very few officially operational ship navigation tunnels both domestically and internationally. However, due to their significant development potential, they have attracted increasing attention and research in recent years. Regarding tunnel safety, research findings on highway tunnels are not applicable to waterway tunnels. In terms of ship navigation safety technology, navigation safety systems for ocean or inland waterway navigation differ greatly from the navigation environment of waterway tunnels; radar, AIS, and other technologies are unsuitable for tunnel environments due to signal shielding. Currently, there is a severe lack of specialized ship navigation risk monitoring and warning equipment for waterway tunnels, essentially a complete absence of such technology.

[0004] In conclusion, it is essential to develop a device suitable for the navigation environment of waterway tunnels, which can provide effective risk monitoring and early warning for the safety of ship navigation in tunnels. Utility Model Content
