Anti-impact navigation mark

Abstract

The invention discloses an anti-impact navigation mark. The anti-impact navigation mark comprises a columnar navigation mark and is characterized by comprising a disc-like watertight buoy surrounding the navigation mark, wherein the inner space of the steel buoy is divided into 8 to 12 cavities by middle separation plates. When the navigation mark is impacted by a ship, the steel buoy around the navigation mark rotates entirely so that by the normal impact speed is changed, most of the energy toward the navigation mark is decomposed and eliminated, and buffer energy dissipation is realized, thus the damage of the navigation mark is greatly reduced and the safety of the navigation mark is ensured; as the watertight steel buoy is divided into multiple cavities, the steel buoy does not sink too much even when individual cavities leak, thereby effectively increasing the security coefficient of valid use; and moreover, the draft of the steel buoy is definite, and the reliable use of the steel buoy is not influence due to the change of water level.

Description

technical field [0001] The invention belongs to the field of water traffic, and in particular relates to an anti-collision navigation mark. Background technique [0002] A navigation mark is a visual, audio and radio navigation aid set up to help ships sail safely, economically and conveniently. It is an important means to ensure smooth water transportation. The navigation mark has four functions, namely, positioning function, danger warning function, confirmation function and indication A traffic function that guides ships along safe paths. A beacon with a specified position in the water and a buoy is called a floating beacon, such as a lightship and a buoy, etc.; while a beacon with a fixed position is called a fixed beacon, such as a lighthouse, a light pole, and a beacon in the water. In order to overcome the shortcomings of buoys that are often displaced, lost and damaged, and to improve the reliability of the location of the buoys, the buoys installed in rivers, lakes...

AI Technical Summary

Problems solved by technology

In recent years, the volume of water transportation in many parts of the country has been increasing rapidly, so the buoys in the waterway have been frequently damaged, resulting in damage to the pile foundation of the buoy and the buoy lights.

In addition, with the trend of large-scale ships, when a ship mistakenly collides with the navigation mark, its impact on the navigation mark will become more and more powerful. As a result, both the navigation mark and the ship will suffer serious losses. While causing huge economic losses, it also directly affects the entire waterway. safe and fast operation
