DETAILED DESCRIPTION - Seawater desalination and power generation with ocean energy resource and its device, comprises using seawater (1), seawater pre-processing system (2), seawater pipe (3), seawater pressure pump (4), seawater high-voltage tube (5), seawater desalination system (6), exhaust water pipe with pressure (7), hydraulic generator system (8), frame platform (9), and energy-collecting machine (10). Several energy-collecting machines under the frame platform support the frame platform and load-carrying devices to float on the surface of the ocean by utilizing their own flotage. Sea water desalination system and hydraulic generator system are installed on the frame platform. Each of the energy-collecting machines has a hinge point to hinge with the frame platform. The other (or more than 1) hinge point of the energy-collecting machine hinges with one end of the seawater pressure pump. The other end of the seawater pressure pump hinges with the frame platform. The energy-collecting machine moves with surging from back to forth and from left to right of the seawater, absorbs the energy of the seawater, arc-swings that takes the hinged joint with the frame platform as the center of a circle in order to make the seawater pressure pump at reciprocating work, and extracts the seawater that has entered the seawater pre-processing system and pressurizes it. High pressure seawater is fed into the seawater desalination system through the seawater high-voltage tube to produce fresh water. The exhaust water pipe with pressure leads the seawater with pressure produced in the fresh water producing in the seawater desalination system into the hydraulic generator system to generate electricity.
