A hybrid mechanism system based on passive compensation and its motion decomposition method

Abstract

The invention provides a hybrid mechanism system based on passive compensation, comprising a hybrid mechanism, a pressure sensor array at the end of the hybrid mechanism, a motion distributor for passive wave compensation, and a hydraulic system of the hybrid mechanism. The hybrid structure includes a six-degree-of-freedom parallel mechanism, a three-degree-of-freedom series mechanism, and a mounting base; the six-degree-of-freedom parallel mechanism consists of six hydraulic cylinders and an upper platform, and the three-degree-of-freedom series mechanism consists of a slewing mechanism, a pitching mechanism, and a telescopic mechanism The installation base is used to fix the hybrid mechanism on the deck of the operation and maintenance ship, and the three-degree-of-freedom series mechanism and the six-degree-of-freedom parallel mechanism are formed by hinge supports. The invention can realize the passive compensation of the offshore operation and maintenance vessel under high sea conditions, and ensure the normal operation and maintenance of the offshore platform in bad weather. Compared with the active ocean wave compensation system, the present invention has the advantages of small energy consumption and low cost, is suitable for short-time and fast operation and maintenance requirements at sea, and has strong practicability.

Description

technical field [0001] The invention relates to a hybrid mechanism system and a motion decomposition method thereof, in particular to a hybrid mechanism system based on passive compensation and a motion decomposition method thereof, belonging to the technical field of marine engineering. Background technique [0002] As the concept of sustainable development is deeply rooted in the hearts of the people, the high energy consumption, high pollution and high emissions of traditional energy sources have caused irreversible damage to the environment, making people pay more attention to the development and use of clean and green energy. Based on this, the development and use of offshore wind energy has entered the vision of various countries, and the number of installed wind turbines has increased significantly, and countries have regarded it as the most important part of the new energy strategy. The state pays great attention to the development of offshore wind power, and has suc...

AI Technical Summary

Problems solved by technology

The wind turbine platform often needs to be repaired and maintained. However, due to the wind and waves at sea, it is very dangerous for people to go from the ship to the platform. It is very necessary for the offshore compensation platform to safely transport personnel and equipment from the ship to the wind turbine platform.
