Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of buoys, in particular to a roll-reducing marine buoy. Background Art
[0002] In recent years, with the booming development of offshore wind farm construction projects, the sea areas for offshore navigation buoy operations have been further expanded. Since the sea areas where offshore wind farms are located are far from the shore, the sea conditions in these areas are often affected by the weather and are relatively harsh. Frontline navigation buoy operators often experience symptoms such as nausea and vomiting, similar to "buoy sickness", during boarding inspections, which seriously affects work efficiency and poses safety hazards.
[0003] When existing marine buoys are in use, their stability is increased by improving buoyancy and durability, but they are insufficient in roll reduction. Rocking and tilting may cause damage to measuring equipment, affecting data accuracy. Due to the rocking motion of the buoy, sensors such as anemometers and thermometers carried on it may not be able to accurately measure, resulting in data deviation. Content of the Utility Model
[0004] The purpose of the utility model is to provide a roll-reducing marine buoy, which reduces the roll of the marine buoy through the set roll-reducing plate, and solves the problem of the shaking of the marine buoy caused by the influence of sea conditions and weather.
[0005] The utility model is realized through the following technical solutions:
[0006] The utility model is a roll-reducing marine buoy, including a buoy body. The buoy body has a buoy drum, and a roll-reducing plate is installed inside the buoy drum. A first water tank, a conduction groove and a second water tank are opened in the roll-reducing plate. The conduction groove is connected to the first water tank and the second water tank. A connection groove is opened on the roll-reducing plate, and a connecting pipe is installed in the connection groove. An installation seat is installed at the bottom of the buoy body. An installation groove is opened in the installation seat, and a counterweight block is slidably matched in the installation groove. A guiding groove is opened on the installation seat, and a guiding block is slidably matched in the guiding groove. A spring is connected between the guiding block and the inner wall of the guiding groove, and a stop block is installed on the outer surface of the guiding block.
[0007] Further, a through hole is opened on the buoy drum, and the connecting pipe is connected in the through hole.
[0008] Further, a sealing cover is installed at one end of the connecting pipe, and the sealing cover is a rubber pad.
[0009] Further, a relief groove is opened on the installation seat, and the stop block is slidably matched in the relief groove.
[0010] Further, a pull rod is installed at the bottom of the stop block.
[0011] The utility model has the following beneficial effects:
[0012] The utility model reduces the roll of the marine buoy through the provided roll reduction plate, significantly improving the stability of the buoy body in a complex marine environment. Moreover, it does not require external energy, reducing the operating cost. At the same time, it improves the reliability of the long-term operation of the buoy body, enabling the monitoring equipment to operate more stably, reducing the measurement error caused by shaking, and thus improving the accuracy of marine data collection.
[0013] The utility model weights the roll reduction plate through the provided counterweight and stop block, enabling the buoy body to stand upright on the sea and avoid deviation towards one side. It can flexibly adjust the draft depth and stability of the buoy body, making it more convenient to operate when the buoy body needs maintenance or upgrade, greatly reducing the maintenance cost and time cost, and being applicable to different wind and wave conditions, thereby increasing the practicality of this device.
[0014] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4The utility model provides a technical solution: a buoy with anti-rolling function at sea, including a buoy body 1, the buoy body 1 has a floating drum 101, a through hole is provided on the floating drum 101, a connecting pipe 3 is connected to the through hole, an anti-roll plate 2 is installed inside the floating drum 101, a first water tank 201, a conducting groove 202 and a second water tank 203 are provided in the anti-roll plate 2, the conducting groove 202 is connected to the first water tank 201 and the second water tank 203, a connecting groove is provided on the anti-roll plate 2, a connecting pipe 3 is installed in the connecting groove, a sealing cover 4 is installed at one end of the connecting pipe 3, and the sealing cover 4 is a rubber The rubber pad can seal the connecting pipe 3 through the provided sealing cover 4. Open the sealing cover 4 to inject water into the first water tank 201 from the connecting pipe 3. When the buoy body 1 is shaken by wind or other influences, the water inside the anti-roll plate 2 will also shake. Since the shaking frequency of the water in the anti-roll plate 2 is similar to that of the buoy body 1, resonance occurs at this time. Since the first water tank 201 and the second water tank 203 are in an inclined state, the water level heights are different, and a roll restoring torque is generated, which is opposite to the shaking direction of the buoy body 1, thereby offsetting the shaking of the buoy body 1.
[0022] The bottom of the buoy body 1 is equipped with a mounting seat 5, and a give way groove is provided on the mounting seat 5. The stopper 8 slides in the give way groove, and the give way groove is connected to the mounting groove 502. When taking out the counterweight 6, the stopper 8 is moved into the give way groove to take out the counterweight 6. A mounting groove 502 is provided in the mounting seat 5, and the counterweight 6 slides in the mounting groove 502. A guide groove 501 is provided on the mounting seat 5, and a guide block 7 slides in the guide groove 501. A spring 9 is connected between the guide block 7 and the inner wall of the guide groove 501. The outer surface of the guide block 7 is equipped with a stopper 8. The stopper 8 A pull rod 10 is installed at the bottom. The pull rod 10 can be used to pull the stop block 8 to move. The counterweight block 6 allows the buoy body 1 to stand on the sea and avoid deviation to one side. The draft depth and stability of the buoy body 1 can be flexibly adjusted. The counterweight block 6 can be replaced according to the water volume inside the anti-roll plate 2. The pull rod 10 is pulled toward the bottom to drive the stop block 8 to move to the bottom along the give way groove and cause the guide block 7 to compress the spring 9. At this time, the counterweight block 6 can be taken out from the installation groove 502 and replaced. Then the pull rod 10 is released and the guide block 7 is pushed by the spring 9 so that the stop block 8 limits the counterweight block 6.
