The invention provides an offshore water dam type wave energy power generation device and a wave energy power generation method. The power generation device comprises high-level water accumulation equipment, a water-turbine generator set, a piston pump, a lever, a rotation fulcrum, a force taking floating box and a fixing platform. The force taking floating box is arranged on the sea surface. The lever is provided with the rotation fulcrum, one end of the lever is fixedly connected with the force taking floating box, and the other end of the lever is fixedly connected with the piston through a piston rod. The offshore water dam type wave energy power generation device and the wave energy power generation method have the beneficial effects that firstly, wave energy is utilized for driving the piston pump, seawater is conveyed to the high position, water potential energy is accumulated, then a power generator is used for power generation and output, and the beneficial effects of the large waterpower potential energy, the high power generation efficiency and the stable electric output are achieved; and secondly, the force taking floating box drives the piston to reciprocate up and down through the lever, the lever with the adjustable fulcrum is arranged, and therefore the stress of the piston end is larger than the floating force of waves to the force taking floating box, and efficient utilization of wave energy is achieved.
Description
technical field [0001] The invention belongs to the technical field of wave energy power generation, and in particular relates to an offshore dam type wave energy power generation device and a wave energy power generation method. Background technique [0002] With the development of the world economy, the surge of population and the progress of society, people's demand for energy is increasing day by day. The vast ocean, which accounts for 70% of the earth's surface area, concentrates 97% of the water and contains a large amount of energy, including wave energy, tidal energy, ocean current energy, temperature difference energy and salinity difference energy. Since wave energy has the least impact on the environment and exists in the form of mechanical energy during the development process, it is the highest grade ocean energy and has broad application prospects. [0003] The main principle of the existing wave energy power generation device is: to convert the motion of ocea...
