Description

Technical Field

[0001] This invention relates to the field of marine engineering equipment, and in particular to a multi-vibration-damping marine observation buoy. Background Technology

[0002] With the increasing demand for marine resource development and environmental monitoring, marine observation buoys, as an important marine monitoring device, are widely used in data collection and transmission in various fields such as marine hydrology, meteorology, and geology. They can acquire various types of marine environmental information in designated sea areas over a long period of time, providing crucial data support for marine scientific research, offshore engineering operations, and disaster early warning and forecasting.

[0003] However, the marine environment is extremely complex and harsh. Under the combined influence of wind, waves, currents, and other factors, buoys inevitably experience vibration and swaying. This vibration can damage the various precision instruments and equipment carried on the buoy, affecting the accuracy of data acquisition, and may also cause fatigue damage to the buoy's own structure, reducing its service life and reliability. Swaying is equally serious, directly affecting the buoy's stability, thus interfering with its normal operation, and may even cause the buoy to deviate from its intended position, affecting the representativeness and continuity of monitoring data.

[0004] Currently, common methods to address the vibration and swaying issues of buoys include increasing the size and weight of the buoys to improve their stability. However, this method often leads to a significant increase in buoy costs and is not conducive to transportation and deployment. Some buoys use electronic vibration damping devices, but these devices usually require additional energy supply, increasing the energy consumption burden of the buoys. Moreover, in the long-term high salt spray and high humidity environment of the ocean, electronic components are prone to failure, affecting the stability and durability of the vibration damping effect.

[0005] In summary, vibration reduction and sway control of marine observation buoys in complex marine environments have become key technical bottlenecks restricting their performance improvement and widespread application. There is an urgent need to develop a more efficient, reliable, economical and adaptable mechanical vibration reduction design scheme to meet the pressing needs of marine observation buoys for long-term stable operation. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a multi-vibration-damping marine observation buoy that is efficient, reliable, economical and highly adaptable, and can meet the urgent needs of marine observation buoys for long-term stable operation, in view of the background requirements and technical difficulties mentioned above.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a multi-vibration-damping marine observation buoy, including a buoy body, an inner ring, a suspension platform, a support assembly, a spring, an observation platform, an auxiliary spring, a pole, general equipment and precision equipment;

[0008] The buoy body has a symmetrical structure with an opening at the top and a reinforcing ring. A primary support is provided inside the reinforcing ring at the axis of symmetry. The inner ring has a double-axis symmetrical structure, with a through hole on the first axis of symmetry and rotatably supported on the primary support of the reinforcing ring, and a secondary support on the second axis of symmetry. The suspension platform has a single-axis symmetrical structure, including a platform plate. An ear plate is provided on the upper side of the platform plate at the axis of symmetry, with a through hole on the ear plate. The platform plate is suspended and supported on the secondary support of the inner ring through the ear plate.

[0009] The support assembly includes a vertical plate, a hinged diagonal bar, and a support plate. The hinged diagonal bar connects the vertical plate and the support plate to form a parallelogram variable mechanism. Two pairs of support assemblies are arranged opposite each other on the axis of symmetry of the suspension platform, and the support plates are connected by springs. The upright is set on the platform plate.

[0010] The observation platform is placed on a support plate, and a limiting plate is provided at the end of the observation platform. An auxiliary spring is provided on the limiting plate. The observation platform has a through hole at the corresponding position of the upright, and the upright passes through the observation platform. The general equipment is installed and fixed on the upright, and the precision equipment is installed and fixed on the observation platform.

[0011] Furthermore, the inner diameter of the through hole on the inner ring is 2-5 mm larger than the outer diameter of the primary support, and the inner surface of the through hole and the outer surface of the primary support are smooth; the end of the primary support is provided with a limiting end cap.

[0012] Furthermore, the inner diameter of the through hole in the ear plate of the bearing platform is 2-5mm larger than the inner diameter of the secondary support, and the inner surface of the through hole and the outer surface of the secondary support are smooth; the end of the secondary support is provided with a limiting end cap.

[0013] Furthermore, the support plate is constructed 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.

[0014] Furthermore, the installation spacing of the support components should be controlled so that the inclination angle of the hinged diagonal bar varies between 20 and 70 degrees, and the inclination angle of the hinged diagonal bar is between 40 and 50 degrees under the self-weight of the observation platform.

[0015] Furthermore, the observation platform can be externally mounted on the support assembly or internally mounted on the support assembly.

[0016] Furthermore, for the externally fastened observation platform, the support plate of the support assembly has an L-shaped structure, the limiting plate is located below the observation platform, and the auxiliary spring is a laminated spring, disposed inside the limiting plate; the distance between the support plates is... l 1. The net distance between the limiting plates is l2. The length of the auxiliary spring is then set to ( l 2- l 1) / 4~( l 2- l 1) / 3, the auxiliary spring is located at the center of the limiting plate, and the spring connection point is located at the center of the support plate.

[0017] Furthermore, for the built-in observation platform, the support plate of the support assembly has a T-shaped structure, the limiting plate is located above the observation platform, and the auxiliary spring is a limiting spring, including an extension rod, an end cap, and a laminated spring. The extension rod passes through the limiting plate and is fixed to the support plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention achieves omnidirectional self-centering stability of the suspension platform relative to the buoy structure through the addition of an inner ring and a suspension base structure to the buoy body. This stability is achieved via alternating perpendicular supports and connections, maintaining the horizontal stability of the platform surface under its own weight. Vibration-damping support components on the platform prevent vertical displacement transmission between the observation platform and the platform. Vertical wave oscillation is buffered by the coordinated deformation of springs and auxiliary springs. The combined design of springs and auxiliary springs provides multi-level buffering and reduces collision effects between the plates. The observation equipment can be installed on the self-centering platform and the vertically vibration-damped observation platform, depending on accuracy and stability requirements. All multiple vibration-damping designs are implemented mechanically, requiring no additional active control or energy input. This approach offers advantages such as high efficiency, reliability, economy, and strong adaptability, meeting the urgent needs of long-term stable operation for marine observation buoys.

[0043] Specifically, the support plate 31 is constructed 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 32.

[0044] Specifically, the installation spacing of the support assembly 4 should control the inclination angle of the hinged diagonal rod 42 to vary between 20 and 70 degrees, and the inclination angle of the hinged diagonal rod 42 should be between 40 and 50 degrees under the weight of the observation platform 6.

[0045] Specifically, the observation platform 6 can be externally mounted on the support assembly 4 or internally mounted on the support assembly 4.

[0046] For the externally mounted observation platform 6, such as Figure 4 and Figure 5 As shown, the support plate 43 of the support assembly 4 has an L-shaped structure, the limiting plate 61 is located below the observation platform 6, and the auxiliary spring 7 is a laminated spring, disposed inside the limiting plate 61; the distance between the support plates 43 is... l 1.

[0048] This invention achieves omnidirectional self-centering stability of the suspension platform 3 relative to the buoy structure by adding an inner ring 2 and a suspension base 3 to the buoy body 1. Through alternating perpendicular supports and connections, the suspension platform 3 maintains horizontal stability under its own weight. The vibration-damping support assembly 4 on the platform 31 blocks the vertical displacement transmission of the observation platform 6 relative to the platform 31. The vertical swaying effect of waves is buffered by the coordinated deformation of springs 5 ​​and auxiliary springs 7. The combined design of springs 5 ​​and auxiliary springs 7 achieves multi-level buffering effects and reduces collision effects between plates. The observation equipment can be installed on the self-centering platform 31 and the vertically vibration-damped observation platform 6, depending on accuracy and stability requirements. All multiple vibration-damping designs are implemented mechanically, requiring no additional active control or energy input. This approach is highly efficient, reliable, economical, and adaptable, meeting the urgent needs of long-term stable operation of marine observation buoys.
