The vibration floater type power generating system is characterized by being composed of a floating body, a casing pipe, a guide rod, an anchor stone, a multi-stage hydraulic assembly, a hydraulic system and a power generator; and the multi-stage hydraulic assembly is sequentially provided with a piston rod, a sleeve and a cylinder barrel from inside to outside, the sleeve is arranged in the cylinder barrel, an outer oil guiding cavity is formed between the sleeve and the cylinder barrel, the piston rod is arranged in the sleeve, an inner oil guiding cavity is formed between the piston rod and the sleeve, an oil guiding cavity is formed in the barrel wall of the sleeve, an upper oil guiding port communicating with the outer oil guiding cavity is formedin the upper end of the oil guiding cavity, a lower oil guiding port communicating with the inner oil guiding cavity is formed in the lower end of the oil guiding cavity, and an oil inlet and an oiloutlet which communicate with the outer oil guiding cavity are formed in the cylinder barrel. The vibration floater type power generating system has the beneficial effects of being simple in structure, safe, reliable and high in wave energy acquisition efficiency.

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.

AI Technical Summary

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
