TECHNICAL FIELD

[0001] The utility model relates to the field of vibration detection especially relates to a marine buoy vibration detector. BACKGROUND

[0002] Marine buoy is a device floating on the surface of the sea or a specific water layer, which is fixed to the predetermined sea area position through anchor chain or other mooring method. As an important part of the ocean observation system, marine buoy undertakes multiple key tasks. Its main functions include real-time monitoring of marine meteorological parameters such as wind speed, wind direction, air temperature, air pressure, etc., and also can collect and transmit data of marine hydrological elements such as current speed, flow direction, water temperature, salinity, etc. These data have irreplaceable important significance for many aspects such as marine scientific research, marine resource development, marine disaster warning and navigation safety guarantee.

[0003] However, marine buoy faces many risks in the marine environment, among which the collision problem is particularly prominent. Due to the increasing traffic of the sea, the passing ships may collide with the buoy due to negligence, equipment failure or bad sea conditions. Once the collision occurs, it may cause serious impact on the buoy in many aspects. First of all, the physical structure is damaged, which may cause the buoy shell to break, the internal frame to deform, and even some functional components such as sensors, data transmission antennas to be directly damaged, affecting its normal data collection and transmission function. Secondly, the impact force generated by the collision may make the buoy deviate from the original position, change its mooring state, and thus affect the accuracy and representativeness of the monitoring data. Moreover, even if the collision does not cause obvious immediate damage, it may cause hidden damage in the internal structure of the buoy, such as loosening of the welding points, wear of the connecting parts, etc. These damages will gradually accumulate and worsen under the continuous action of subsequent sea waves, ocean currents, etc., eventually leading to the performance degradation or even complete failure of the buoy.

[0004] In view of the serious consequences that may be caused by the collision of marine buoy, the importance of vibration monitoring is highlighted. By monitoring the vibration of marine buoy in real time, it can be found out whether the buoy is subjected to collision or other abnormal external force SUMMARY
