The marine environment online monitoring system is required to be completely automatically operated under an unattended condition to realize continuous marine environment monitoring in real time, so as to cope with severe challenges such as high temperature, high salinity, high humidity and biological adhesion. Thus, many technologies are provided in the prior art to solve the above-mentioned problems. For example, Chinese patent No. CN 114435542 B provides a buoy mechanism for monitoring a marine environment, in which an anti-collision strip is designed to achieve an effect in protecting a buoy. Specifically, an end of the anti-collision strip tilts upward under the action of buoyancy and floats on the sea surface. Therefore, if a ship hull or another floating object collides with the buoy, the end of the anti-collision strip tilting upward will be collided preferentially, such that an upper end of the ship hull or the floating object is prevented from tilting outward and from further colliding with a monitoring mechanism at an upper end of the buoy body, thereby achieving a good effect in protecting the monitoring mechanism on the buoy. However, the technology in terms of buoy protection such as sea current impact prevention in the prior art still has room for improvement.
