Accurate positioning buoy device for suspension anchor cable based on constant tension control

Abstract

The invention discloses an accurate positioning buoy device for a suspension anchor cable based on constant tension control. The device comprises an anchorage, an anchor chain, a plurality of buoyancyballs, a buoy and a buoy lamp bracket; one end of the anchor chain is located in the middle of the upper end of the anchorage, the plurality of buoyancy balls are distributed along the anchor chain,and the buoy lamp frame is positioned at the upper end of the buoy; a winding drum and a driving device used for driving the winding drum to rotate are arranged at the upper end of the inner cavity ofthe buoy, a cable is wound on the winding drum, the free end of the cable penetrates out of a cable guide hole in the inner cavity of the buoy and is connected with the other end of the anchor chain;and a tension sensor used for detecting tension of the cable is further arranged at the upper end of the inner cavity of the buoy. According to the accurate positioning buoy device, the anchor chainis perpendicular to the horizontal plane through the arrangement of the buoyancy balls, the buoy can be kept at the working position all the time, and the positioning is accurate; through the arrangement of the tension sensor and the positioning device, when the buoy is deviated, the buoy can return to in-situ; the length ratio of the anchor chain and the cable is optimized, so that the required power of the winding drum for driving the reeling and unreeling cable is the minimum.

Description

technical field [0001] The invention relates to a novel buoy device, in particular to a buoy device for precise positioning of a suspended anchor cable based on constant tension control. Background technique [0002] Buoys are artificial signs that help and guide ships to navigate, locate and mark obstacles to indicate warnings. They provide safety information for various water activities and position guarantees for the safety of ships during normal navigation. At present, most of the buoys are passive devices. During the operation, the buoys will be affected by water flow, wind force and ship collision. These adverse effects will cause the buoys to deviate from their original positions. The deviation of the buoys from their original positions will lead to inaccurate information indicated by the buoys. affect the driver's judgment. When it is more serious, it may cause the ship to deviate from the channel, and the ship will be stranded, overturned, collided and other genera...

AI Technical Summary

Problems solved by technology

At present, most of the buoys are passive devices. During the operation, the buoys will be affected by water flow, wind force and ship collision. These adverse effects will cause the buoys to deviate from their original positions. The deviation of the buoys from their original positions will lead to inaccurate information indicated by the buoys. affect the driver's judgment

In more serious cases, it may cause ships to deviate from the waterway, and ship grounding, capsizing, collisions and other general damage accidents will seriously threaten the safety of ship navigation.
