Rolling floater cable moving type shoreside wave power generation device

Abstract

The invention relates to a power generation device, in particular to a rolling floater cable moving type shoreside wave power generation device taking sea shoreside wave energy as a power source. The device comprises a rolling floater which is positioned on shoreside sea surface and can convert complex and changeable shoreside wave motion into simple vertical mechanical motion of a transmission rod regardless of raising tide or falling tide. The simple vertical mechanical motion of the transmission rod is converted into back and forth motion of a pulling cable; the back and forth motion of the pulling cable drives a unidirectional chain wheel meshed with the pulling cable to perform back and forth rotation through a connecting chain; the back and forth rotation of the unidirectional chain wheel continuously transfers power to a coaxial clockwork; the clockwork drives a speed increaser to drive a generator to efficiently and stably generate power at high speed and to output constant current. The rolling floater can be pulled up from the sea surface so as to avoid risk in violent typhoon weather. The device requires that a plurality of single wave power generation devices are combined to generate power and output powerful constant current. The device has the advantages that the structure is simple, plants are built on the land, no moving components exist in the water, the device can resist typhoon, and large wave power stations can be built.

Description

technical field [0001] The invention relates to an energy conversion technology, in particular to the technology of generating electricity by using ocean shore waves. Background technique [0002] Now energy shortage and environmental pollution have become major problems facing the world. More than 70% of the Earth's surface is covered by oceans. The vast ocean contains huge energy. Taking wave energy as an example, it has the characteristics of high energy density and wide distribution. Ocean wave energy is one of the inexhaustible renewable clean energy sources, much superior to wind energy and solar energy, and is a long-term wish of people. Since ancient times, it has attracted skilled craftsmen along the coast, trying various methods to control the waves for human use. Ocean wave energy scholars now estimate that waves travel thousands of kilometers in the ocean without significant attenuation, and finally gather on the shore. Some people have done a test, the impac...

Problems solved by technology

Most of the wave power generation devices invented at present are placed in the water. Typhoon weather often occurs in the marine environment, which will damage the underwater devices, sea water will corrode the marine devices, and shellfish will parasitize the underwater devices, making the devices easy to damage
