Problems solved by technology
[0003] However, due to the characteristics of low frequency, low energy density and uncertain direction of waves, it is difficult to effectively collect wave energy.
As the current mainstream energy harvesting technology—electromagnetic generator, due to its poor low-frequency collection efficiency, large driving force requirements, fixed direction, and bulky characteristics, it is difficult to be widely used on the sea to collect wave energy.

The invention discloses a sea wave energy collection device and sea power generation equipment. The wave energy collection device includes a balance part that can float on the water surface, and a weight part is arranged at the center of the bottom; a cylindrical support part is arranged on the top of the balance part, and a swinging piece is suspended inside it, and the swinging piece can swing in the support part; The power generation part is arranged in the support part, including a ring-shaped flexible base plate and a first friction pair and a second friction pair respectively arranged on the outer side and the inner side of the base plate. The base plate surrounds the swing member, and the number of base plates is one or nested in sequence When the swinging member swings, it can drive the deformation of the base plate. With the deformation of the base plate, contact and separation occur between the swinging member and the second friction pair of the innermost base plate to generate electrical output. The first friction pair of the base plate Contact and separation between the pair and the second friction pair of the outer adjacent base plate produces an electrical output. The ocean wave energy collection device of the invention can realize the collection of ocean wave energy in any direction, and has high power generation efficiency.
Description
technical field [0001] The invention relates to the technical field of ocean energy collection, in particular to an ocean wave energy collection device and offshore power generation equipment. Background technique [0002] As the most important part of the earth's surface, the ocean contains abundant and renewable blue energy. Among them, wave energy, as the main component of blue energy, is regarded as one of the most potential ways to solve human's future energy problems. [0003] However, due to the characteristics of low frequency, low energy density and uncertain direction of waves, it is difficult to effectively collect wave energy. As the current mainstream energy harvesting technology—electromagnetic generator, due to its poor low-frequency collection efficiency, large driving force requirements, fixed direction, and bulky characteristics, it is difficult to be widely used on the sea to collect wave energy.
