Description

Technical Field

[0001] The invention relates to the field of marine engineering equipment, and in particular to a marine observation buoy with multiple vibration reduction. Background Art

[0002] With the increasing demand for marine resource development and environmental monitoring, marine observation buoys, as an important marine monitoring equipment, are widely used in data collection and transmission in marine hydrology, meteorology, geology, etc. They can obtain various marine environmental information in a long-term and stable manner in designated sea areas, and provide key data support for marine scientific research, offshore engineering operations, and disaster warning and forecasting.

[0003] However, the marine environment is extremely complex and harsh. Under the combined effects of wind, waves, currents and other factors, the buoy will inevitably vibrate and sway. This vibration will not only cause damage to the various precision instruments and equipment carried by the buoy, affecting the accuracy of data collection, but may also cause fatigue damage to the buoy's own structure, reducing its service life and reliability. The swaying problem should not be ignored either. It will directly affect the stability of the buoy, thereby interfering with its normal operation, and may even cause the buoy to deviate from the predetermined position, affecting the representativeness and continuity of the monitoring data.

[0004] At present, in order to deal with the problem of buoy vibration and swaying, common methods include increasing the size and weight of the buoy to improve its stability, but this method often leads to a significant increase in the cost of the buoy and is not conducive to transportation and deployment; some buoys use electronic vibration reduction devices, but these devices usually require additional energy supply, which increases the energy consumption burden of the buoy, and in the long-term high salt fog and high humidity environment of the ocean, electronic components are prone to malfunction, affecting the stability and durability of the vibration reduction effect.

[0005] In summary, the vibration reduction and sway control problems of offshore observation buoys in complex marine environments have become a key technical bottleneck restricting their performance improvement and wide application. It is urgent to develop a more efficient, reliable, economical and adaptable mechanical vibration reduction design scheme to meet the urgent needs of offshore observation buoys for long-term stable operation.

[0010] Furthermore, the base plate is made of concrete or metal blocks and has sufficient weight to achieve suspension stability through its own weight under the suspension support connection of the upper ear plate.

[0011] Furthermore, the installation spacing of the support components should control the inclination angle of the articulated diagonal rod to be between 20-70 degrees, and the inclination angle of the articulated diagonal rod under the dead weight of the observation platform is between 40-50 degrees.

[0012] Furthermore, the observation platform can be placed on the support assembly in an external manner, or can be placed on the support assembly in an internal manner.

[0013] Furthermore, for the external buckle observation platform, the support plate of the support assembly is an L-shaped structure, the limit plate is located below the observation platform, and the auxiliary spring is a laminated spring, which is arranged on the inner side of the limit plate; the distance between the support plates is l 1.

The vertical displacement transmission of the observation platform relative to the pedestal plate can be blocked by the vibration-damping support assembly on the pedestal plate, and the vertical swing effect of the waves is buffered by the coordinated deformation of the spring and the auxiliary spring.
