Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] First of all, the general introduction of active motion suppression devices for offshore floating scientific research platforms is as follows:

[0038] It mainly includes wave environment monitoring and motion forecasting module, active motion suppression module and power generation module.

[0039] The wave environment monitoring and motion forecasting module consists of a wave measuring radar and a platform motion forecasting system, both of which are located on the upper part of the platform deck. Among them, the wave measuring radar is used to monitor the wave environment conditions around the platform in real time. It can observe the incoming waves far away from the platform and obtain relevant wave elements (wave height, wavelength, wave steepness and wave period, etc.), and then obtain the wave Spectral density; the motion foreca...

Abstract

The invention relates to an active motion suppression device for an offshore floating scientific research platform. The two ends of folding canvas are fixed to a pair of rigid movable supports; the wave measuring radar can monitor the sea wave environment condition far away from the platform in real time and obtain wave data, and the controller controls the rigid moving support to move to the position where the floating platform is prevented from generating the heaving motion trend under the influence of waves in advance according to the wave data. The controller can judge the force application direction of waves to the folding canvas in real time according to the damping direction of the damping sensor, so that the driving device is controlled to drive the rigid moving support to move along the sliding rail, the middle of the folding canvas is aligned with the center of the waves, and the folding canvas is unfolded as much as possible. The purpose of reducing heaving, rolling and pitching motions of the platform at the same time is achieved. In addition, the device can also effectively utilize ocean wave energy to generate electricity, so that electric energy supply is continuously provided for the offshore floating type scientific research platform.

Description

technical field [0001] The invention relates to an active motion suppression device and a suppression method for an offshore floating scientific research platform, belonging to the technical field of offshore platforms. Background technique [0002] Today, understanding and developing the ocean has become the consensus of human beings to expand their living space. Sea-related activities are in full swing, and a new round of ocean competition around the world is intensifying. The development of high-end marine equipment such as offshore floating platforms is the only way to accelerate the construction of a maritime power and a key measure to grasp the dominance of future marine development competition. [0003] The offshore floating scientific research platform with marine scientific research, experiment and observation as the main task is sensitive to the stability of the platform due to the accuracy of the test equipment and measuring instruments arranged on it, especially ...
