Power generating unit for generating power by using ocean wave

Abstract

The invention discloses a power generating unit for generating power by using ocean waves. The power generating unit comprises a power generating unit shell. A guide rod and an inertia mass body which can slide up and down along the guide rod are arranged in the power generating unit shell. A tension spring and a compression spring which keep the inertia mass body be suspended in air are correspondingly arranged at the upper end and the lower end of the internal part of the power generating unit shell. A power generator is arranged on the inertia mass body. A rack bar is arranged in the power generating unit shell. A drive gearbox is arranged on the inertia mass body. A gear arranged at the input end of the driver gearbox is engaged with the rack bar. The output end of the drive gearbox is connected with the shaft of the power generator. The invention has the advantages that the structure is simple, the wave absorbing capacity is strong, the expense is low, different scales of power plants can be constructed and the like. The power generating unit is used on ocean wave power generating sets.

Description

【Technical field】 [0001] The invention relates to a power generation unit, in particular to a power generation unit for ocean wave power generation. 【Background technique】 [0002] Because wave power generation has the advantages of no pollution and no need to consume fuel, how to use the energy carried by seawater waves to generate power has become the research goal of marine engineering researchers all over the world. my country's mainland coastline is more than 18,000 kilometers long, plus various large and small islands, marine energy is very rich. As renewable energy becomes increasingly tense, researching and innovating marine power generation technology is a work of far-reaching significance. [0003] For more than ten years, the research on wave power generation at home and abroad is still in the exploratory stage. Advanced countries started research earlier, and the power generation devices are also different, but it is difficult to enter the stage of popularizati...

AI Technical Summary

Problems solved by technology

Advanced countries started research earlier, and the power generation devices are also different, but it is difficult to enter the stage of popularization and application, because they all encounter the common problem, that is, the investment cost is high and the recovery is too slow, and even the management fee cannot be recovered.

[0004] The relatively successful foreign wave power generation device is the "moray eel", which does a good job in absorbing as much wave energy as possible, but it is difficult to solve the above-mentioned "investment and recovery" problem. In recent years, Portugal has put this device Successfully connected to the grid, but it does not mean that the application can be promoted

In addition, Copenhagen, Sweden successfully solved the offshore safety of wave power generation, but in addition to the cost and recovery problems, it also has the disadvantage of not strong power generation capacity
