A Suspended Anchor Cable Accurately Positioning Buoy Device Based on Constant Tension Control

technical field

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

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 general damage accidents, which seriously threaten the safety of the ship's navigation.

The suspended anchor cable based on constant tension control accurately locates the underwater part of the buoy device: the cable and the anchor chain are connected by an anchor shackle, and several buoyancy balls are installed on the anchor chain. Matching the weight of the anchor chain, the bottom of the anchor chain is connected to the anchorage of the buoy device.

Compared with prior art, the beneficial effect of the present invention is:

1. Through the setting of the buoyancy ball, the anchor chain is perpendicular to the horizontal plane, and the buoy can always be kept in the working position, and the positioning is accurate;

2. Through the setting of the tension sensor and the positioning device, when the buoy deviates, it can return to its original position;

3. Optimize the length ratio of the anchor chain and the cable to minimize the power required to drive the reel for retracting and unwinding the cable;

4. The working diameter (allowable drifting position) of the present invention can be set according to needs, ensuring the safety of the waterway;

5. Due to the setting of the buoyancy ball, the buoyancy generated by the buoy hardly needs to bear the weight of the anchor chain;

6. The number of buoyancy balls matches the weight of the anchor chain;

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figures 1 to 5, most buoys are passive devices. During operation, buoys will be affected by water flow, water level, wind force, and ship collisions. These adverse effects will cause the buoys to deviate from their original positions Some positions lead to inaccurate information indicated by buoys, which affects the safety of ship navigation. The suspension anchor cable based on the constant tension control of the present invention precisely locates the buoy device,

First, the anchorage 1 is sunk into the bottom sediment by its own weight to fix the position; the anchor chain 2 is equipped with several buoyancy balls 3 to keep the anchor chain vertical. The anchor chain 2 and the cable 5 are connected by an anchor shackle 4, and the other end of the cable 5 is wound on the reel 7; the reel 7 and the motor 8 are located inside the buoy 9 and do not touch the water. The barrel 7 rotates forward or reversely to retract the cable 5, and the electric motor 8 is powered by a storage battery or a solar cell. The buoy light frame 10 is provided with a GPS or Beidou positioning device, so that it can output position signals at any time. The outer wall of the tension sensor 11 is provided with two auxiliary pulleys 11.1 and a detection pulley 11.2 vertically arranged; The detection end is connected and squeezes the cable 5 between the two auxiliary pulleys 11.1. The tension sensor 11 monitors the tension of the cable 5 in real time. When the detected tension is less than the preset value, the motor 8 is controlled to rotate forward to tighten the cable 5. When the detected tension is greater than the preset value, the motor 8 is controlled to reverse and release the cable 5. When wind and waves or tides, or external disturbances such as ship collisions, make the buoy 9 position deviation exceed the set value, the positioning device starts to work, and the control motor 8 is forwardly rotated to tighten the cable 5, so that the buoy 9 gets back to the set position. If the wind and waves are large, causing the tension of the cable 5 to exceed the set value of the tension sensor 11, the braking device makes the reel 7 no longer rotate to reduce energy consumption. The motor 8 makes the cable 5 retract and retract slowly, so that the buoy 9 always works in the set area.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the various embodiments of the present invention. scope.
