Swing-mechanical wave power generation device

Abstract

The invention provides a swing-mechanical wave power generation device, which comprises a case, a generator, an energy-storage flywheel, a one-way movement transfer mechanism, a floater and a connecting rod. The generator, the energy-storage flywheel and the one-way movement transfer mechanism are arranged in the case, the energy-storage flywheel is arranged on an output shaft of the one-way movement transfer mechanism, the generator is connected with the output shaft of the one-way movement transfer mechanism, and the floater is connected with an input shaft of the one-way movement transfer mechanism through the connecting rod. The wave collecting floater is in the shape of a duck belly, so that heaving and rolling movements of waves can be effectively captured. The one-way movement transfer mechanism is adopted to transfer the swing of the duck-belly type wave collecting floater into one-way movement on the output shaft, so that the use efficiency of the wave energy can be greatly increased. The energy-storage flywheel is arranged on the output shaft, so that the output on the output shaft can be more stable, and the stability and efficiency of the system is improved.

Description

technical field [0001] The invention relates to a clean energy generating device. Background technique [0002] The use of ocean energy is the direction of energy research in the world today. Especially in the situation where energy is related to national security, energy is gradually depleted and environmental conditions are deteriorating, how to effectively utilize resource-rich and renewable marine resources is very important. At present, the existing mechanical wave power generation device mainly uses the movement of waves to push the active parts of the device - rafts, floats, etc., to compress (drive) intermediate media such as oil, water, air, etc., and push the conversion power generation device to generate electricity through the intermediate medium. . [0003] Chinese patent application number 200710191545.5 discloses a wave power generation device, which is provided with a buoyant device on the transmission shaft, and the gear and sprocket on the transmission sh...

AI Technical Summary

Problems solved by technology

This invention has two deficiencies: 1. The fluctuation frequency of waves is low, so the rotational speed on the power output shaft is not high. If no speed increase or other means are used, the power generation efficiency is quite low and the practicability is poor; 2. .Due to the long fluctuation period and low frequency of waves, the rotation of the power output shaft must be intermittent. If no mechanical energy storage device is added, its efficiency is extremely low

This invention has two deficiencies: 1. The wave power plate only absorbs the driving force of the wave, and does not make good use of the buoyancy of the wave, so the wave utilization rate is low; 2. The device adopts a speed-up mechanism, which is difficult to install and difficult to maintain Large, the length of the transmission chain is increased, the efficiency of the whole device is greatly reduced, and the starting torque at the input end is greatly increased
