Navigation mark protection device

Abstract

The invention belongs to the technical field of navigation marks, and discloses a navigation mark protection device. The navigation mark protection device comprises a main mark ship and an auxiliary mark ship. The main mark ship is provided with a navigation mark lamp and a first anchor cable pile. The front end and the rear end of the auxiliary mark ship are each provided with a second anchor cable pile. The auxiliary mark ship is further provided with an automatic alarming device. When the included angle between the auxiliary mark ship and the horizontal direction is larger than or equal tothe set angle, the automatic alarming device can send an alarming signal. When the navigation mark protection device is applied, when a huge winding material generates tension through water flow, onlythe auxiliary mark ship for protecting can be pulled to be sunken, the buoyancy force of the auxiliary mark ship counteracts pull sinking force, the navigation mark lamp on the main mark ship is protected, the situation that the navigation mark lamp loses the effect or is damaged due to the fact that the main mark ship is inclined or is tuned over and sunken is avoided, meanwhile, alarming can besent timely to a construction brigade for processing the winding material on the auxiliary mark ship and overhauling the auxiliary mark ship, and normal passage of a navigation channel is ensured.

Description

technical field [0001] The invention belongs to the technical field of navigation aids, and in particular relates to a navigation aid protection device. Background technique [0002] Navigation marks are used to indicate the direction and boundaries of navigation channels, help guide ships to navigate, locate and mark obstructions and artificial signs indicating warnings. They are set in navigable waters to mark the positions of navigation channels, anchorages, shoals and other navigation marks, and to identify water depth and style. , to direct the traffic in narrow waterways, its role is: during the day, the ship pilots observe the navigation mark as the main reference for navigation, and at night it is an important navigation aid to support the navigation light. During the flood season when the water rises sharply or when the flood level is high, there are a lot of floating objects (weeds, driftwood, plastic bags, etc.) on the river surface. It is necessary to remove the...

AI Technical Summary

Problems solved by technology

During the flood season when the water rises sharply or when the flood level is high, there are a lot of floating objects (weeds, driftwood, plastic bags, etc.) on the river surface. Floating objects need to be removed in time. If not removed in time, the navigation mark will deviate from the original position, which cannot play the role of warning indication, or even make wrong instructions, resulting in irreparable losses.
