Spherical buoy and manufacturing method thereof

Abstract

The invention discloses a spherical buoy and a manufacturing method thereof. The spherical buoy comprises a spherical buoy body. The spherical buoy is characterized in that the periphery of the spherical buoy body is smooth, the spherical buoy body is provided with an upper top cover and a lower bottom cover, the upper top cover, the lower bottom cover and the spherical buoy body form three cavities from top to bottom, i.e. a first cavity, a spherical buoy body cavity and a second cavity, the spherical buoy body cavity is a cylindrical cavity, and a foam body is arranged at the periphery of the cylindrical cavity. The spherical buoy has the advantages of good gesture stability, simple structure and low cost.

Description

technical field [0001] The invention belongs to the mechanical structure of marine instruments, in particular to a spherical buoy and its manufacturing method. Background technique [0002] Spherical ocean buoys have been widely used as a platform for various marine environment detection instruments, and have become one of the main tools for marine environment monitoring. [0003] The traditional spherical buoy structure is usually composed of two complete hemispherical buckles, and some covers are designed with sealing rings on the hemispherical structure for the convenience of equipment installation. Both hemispheres are designed with flanges (with sealing rings). The screws are fastened as a whole, and the periphery of the flange is covered with a rubber ring to play the role of anti-collision buffer. There are the following problems in such a structural form: [0004] (1) Due to the existence of the flange and the anti-collision rubber ring, the smoothness of the surfa...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the existence of the flange and the anti-collision rubber ring, the smoothness of the surface of the spherical buoy is affected, and the non-uniform impact of waves on the buoy is increased, causing the buoy to roll and destroying the attitude stability of the buoy

The instability of buoy attitude will inevitably lead to the decrease of the accuracy of buoy attitude measurement and compensation, which will affect the measurement accuracy of marine instruments carried by buoys;

[0005] (2) The position of the flange is the part of the spherical buoy with the largest size, the most vulnerable to impact, and relatively weak mechanical strength. Under external impact, even with the protection of the anti-collision rubber ring, there is no guarantee that no deformation and cracks will occur. , prone to water leakage, resulting in damage to the carrying equipment, or even sinking the entire buoy;

[0006] (3) The production of spherical buoy shells requires high-precision molds, and the use of flanges and anti-collision rubber rings increases material consumption, resulting in higher production costs for buoys (this is especially important for consumable drifting buoys). Increased self-weight, decreased carrying capacity, etc.
