Problems solved by technology
[0003] At present, the oscillating buoy type power generation system includes the following methods: 1. The existing floating body sheave wave power generation technology with springs for rope collection has serious defects such as short spring fatigue life, weak rope collection ability, and rope wear; 2. The existing counterweight The floating body rope pulley wave power generation technology for receiving the rope is easily affected by floating objects in the ocean due to the external counterweight, so the reliability is poor; 3. The existing vacuum cylinder for floating body sprocket wave power generation system: ①The reliability of the vacuum cylinder is poor: vacuum The precision of the cylinder is high, and the chain is prone to shaking during the lifting of the floating body
If the amount of shaking is too large, the vacuum cylinder will be damaged due to the collision of the chain
②The problem of inability to overcome the tidal range: In order to overcome the tidal range, the length of the vacuum cylinder and the chain must be increased, which not only increases the cost, but also increases the shaking of the chain, making collisions more likely

Description
technical field [0001] The invention relates to the technical field of wave energy power generation systems, in particular to an oscillating float type power generation system with simple structure, safety and reliability, less energy loss and high wave energy collection efficiency. Background technique [0002] As we all know, with the implementation of the national marine strategy, the power consumption at sea is increasing day by day. At the same time, the environmental problems caused by the frequent use of fossil energy are becoming more and more serious, which makes it urgent to develop clean new energy. As a green renewable resource, ocean wave energy has large reserves, wide distribution, and high energy flow density. It can effectively alleviate the world's energy tension, improve environmental problems, and provide convenient and cheap energy demand for ocean observation and development. [0003] At present, the oscillating buoy type power generation system includ...
