Abstract

The invention discloses a wave power generation device with a rope structure. The wave power generation device mainly comprises a machine frame assembly, a floating platform assembly, three evenly-distributed driven constraint branched chains, three rope branched chains and a hydraulic power generation system, wherein the three driven constraint branched chains are installed on the machine frame assembly and are of the same structure, and the three rope branched chains are of the same structure and are evenly distributed in the circumferential direction. Main movement of waves is converted into moving and swing of floaters, the floaters drive a rope to move, then, moving and swing are converted into rotation of a crank disc, and the wave power generation device can well adapt to wave movement, is not restricted by the wave height, and has the advantages that subjected impact force is small, the wave energy recycling rate is high, the structure is simple, the input-output ratio is low,protection performance is good, and manufacturability is good.

Description

Technical field [0001] The present invention relates to the field of power generation technology, in particular to an ocean wave energy power generation device. Background technique [0002] The ocean occupies about 71% of the earth's area. Due to the influence of air pressure and sea wind, waves are generated on the ocean surface almost all the time. This regular and periodic sea water undulating motion contains huge energy. With the increasingly prominent issues of "global warming" and "energy depletion", international scholars are paying more and more attention to the recycling and utilization of this new type of renewable energy. [0003] After years of development, many wave energy generating devices have been proposed. Most of these wave power generation devices adopt series or parallel structure. Among them, the energy absorbing mechanisms of ocean wave power generation devices based on the series structure are mostly single-degree-of-freedom mechanisms. Due to their less...

Problems solved by technology

Among them, the energy-absorbing mechanism of the ocean wave power generation device based on the series structure is mostly a single-degree-of-freedom mechanism. Due to its small degree of freedom, it cannot make full use of the movement of waves, resulting in a low recovery rate of wave energy for this type of power generation device.

The energy-absorbing mechanisms of marine wave power generation devices based on parallel structures all adopt multi-degree-of-freedom mechanisms, which can well adapt to the multi-degree-of-freedom compound motion of ocean waves; however, most of these power generation devices rely on the reciprocating motion of the telescopic rod in the energy-absorbing mechanism to recover energy , in the design process, in order to make the power generation device adapt to the seasonal changes of wave height, the limit stroke of the telescopic rod needs to be designed very large. In this way, not only the volume of the power generation device is increased, but also the manufacturing cost of the power generation device is increased. , which also reduces the utilization efficiency of the power generation device; in addition, the energy recovery and conversion components of this type of power generation device are relatively close to the seawater and move in real time with the waves, which are not easy to protect and are easily corroded by seawater, thus reducing their reliable operation. sex and working life
