Embodiment Construction

[0036] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The invention belongs to the field of wave energy power generation, and specifically relates to a method of driving the piston of a piston pump to move up and down through the action of sea waves on a force-taking buoy, thereby lifting seawater to a high-level water tower, and then using the potential energy of the water level drop to drive a water turbine to generate electricity.

[0038] In traditional wave energy power generation, energy harvesting facilities generally float on the water surface, and the energy collected is only wave waves on the water surface. ...

Abstract

The invention provides a water tower type wave energy power generation device and method. The device comprises an underwater piston unit, a piston motion driving unit and a high-position energy storage power generation unit. The high-position energy storage power generation unit comprises a high-position water tower, a water-turbine generator set, a water diversion pipe and a return pipe; the piston motion driving unit comprises a power take-off buoy; and the underwater piston unit comprises a piston pump cylinder, a piston is installed in the piston pump cylinder in a lifting sliding sealing mode, and the axis of the piston is fixed to one end of a piston lifting traction cable. The other end of the piston lifting traction cable penetrates through a top sealing cover of the piston pump cylinder in a sealed mode and then is coaxially installed on the axis of the power take-off buoy. The device and method have the following advantages: (1) most facilities are arranged in a still water area below the sea surface, so that the influence of stormy waves is avoided, and the safety and the stability are greatly enhanced; (2) scattered wave energy is gathered through the piston pump and the high-position water tower, and stable power generation can be achieved; and (3) the offshore construction difficulty is greatly reduced due to the suspension design of underwater facilities.
