Abstract

The invention discloses a float-chain offshore wave energy collecting device which comprises a large float floating on water, a small float suspending in the water, a transmission chain connected between the large float and the small float, and a mounting case arranged on a seabed in a sinking manner, wherein a chain wheel driven by the transmission chain, a hydraulic pump driven by the chain wheel and a mechanical transmission system for transferring a fixed torque between the chain wheel and the hydraulic pump are arranged on the mounting case, and the transmission chain rounds the lower portion of the chain wheel. The device is simple in structure and convenient to mount and dismount, the transmission chain is pulled by buoyancy of the large float and the small float to rotate the chain wheel, the chain wheel rotates to generate a torque force which is transmitted to the hydraulic pump through the mechanical transmission system, and the input torque of the hydraulic pump is kept fixed to ensure that the hydraulic pump outputs stable high-pressure seawater.

Description

technical field [0001] The invention belongs to a wave energy collection device, in particular to a float-chain offshore wave energy collection device. Background technique [0002] The energy contained in waves mainly refers to the kinetic energy and potential energy of ocean surface waves. The huge waves caused by typhoons have a power density of thousands of kW per meter of the wave surface, while the annual average wave power in the European North Sea region, which is rich in wave energy, is only 20-40kW / m 2 , the annual average wave power density of most of the coast of China is 2-7kW / m 2 . [0003] The theoretical estimate of wave energy in the world is also on the order of 109kW. It is estimated by using the data of China's coastal ocean observation stations that the theoretical annual average power of China's coastal waves is about 1.3X10 7 kW. However, since the observation sites of many marine stations are located in inner bays or where the wind and waves are ...
