Offshore floating body type suspended oscillating wave power generation device

Abstract

The invention relates to an offshore floating body type suspended oscillating wave power generation device which comprises a mother ship and a water chamber arranged on the mother ship. A water chamber opening is formed in one end of the mother ship. The offshore floating body type suspended oscillating wave power generation device is characterized in that an oscillating assembly adjustable in center of gravity is arranged in the water chamber; the power generation device further comprises a vibration damping plate and a power generation control assembly; the vibration damping plate is connected with the another end of the mother ship; an upright column is arranged on the vibration damping plate; the bottom end of the upright column is fixed at the sea bottom; the power generation control assembly is connected with the oscillating assembly. Compared with the prior art, the offshore floating body type suspended oscillating wave power generation device is capable of floating offshore to collect wave energy, and the parameters of the device can be adjusted according to the wave working conditions within a certain range so that the energy conversion efficiency can be improved; besides, the device is low in site selection limitation, flexible, and excellent in adjustability.

Description

technical field [0001] The invention relates to a new energy technology, in particular to an offshore floating body type suspended pendulum wave power generation device. Background technique [0002] All countries in the world are studying energy countermeasures and national energy strategies. It is estimated that marine energy accounts for more than 70% of the world's total energy. Countries around the world have listed the ocean as a key resource for competition. Ocean energy is an important renewable energy. The energy density of ocean wave motion is very high, and it spreads widely in the ocean. Because of this, the energy of waves can be used even thousands of miles away from the ocean. During this long journey, the waves gradually stabilize, and in suitable areas, ocean energy can be efficiently regenerated and electricity generated. According to calculations, on each square kilometer of sea surface, the moving waves contain about 300,000 kilowatts of energy. Accor...

Problems solved by technology

Then the device has the following defects: the first, the center of the pendulum plate of the device is a fixed value, which can not make good use of the wave force energy of the waves for the subtropical monsoon climate sea area where the wave wavelength varies greatly with the seasons; The distance between the vertical plate and the pendulum shaft in the power generation device cannot be adjusted, which cannot protect the structure of the power generation device well; third, the power generation device increases the distance between the vertical plate and the mother ship by lengthening the The base lowers the center of gravity to make the device float stably on the sea surface, but for the erratic subtropical monsoon climate sea area, it is often not firm enough to be fixed only by buoyancy without fixing

[0015] In addition, the Chinese patent with the publication number CN103403343A discloses a hydraulic circuit for a hanging pendulum type wave power generation device, but the circuit is equipped with two hydraulic motors, and the system stability is insufficient
