1. An offshore floating platform device, comprising a pontoon carrier component,
wherein the pontoon carrier component comprises a pontoon (101);
wherein a counterweight body is provided at a bottom of the pontoon (101), and a central cylinder (102) is provided at a top of the pontoon (101); wherein an anchor chain component is provided on an outer cylindrical surface of the pontoon (101) for keeping an elevation of the pontoon carrier component in a sea;
wherein a platform (103) is provide around an edge of a top surface of the central cylinder (102); wherein a plurality of tower bases (104) is provided on the top surface of the central cylinder (102) for installing a tower (3) of a wind turbine (2); wherein a buoyancy support component is provided on an outer cylindrical surface of the central cylinder (102);
wherein the buoyancy support component is configured to ascend and descend as it rolls along the outer cylindrical surface of the central cylinder (102) in response to changes in water level;
wherein the buoyancy support component comprises two symmetrical semi-circular ring-shaped pontoon boxes (401);
wherein the two pontoon boxes (401) are arranged around an outer side of the central cylinder (102) and are spliced to form a pontoon box body, wherein the pontoon box body is located below a sea surface;
wherein a plurality of columns (4021) is evenly distributed on an inner edge of a top surface of each of the two pontoon boxes (401), wherein the columns (4021) are connected from top to bottom through a plurality of horizontal arc beams (4022) to form one force transmission frame (402);
wherein two force transmission frames (402) are arranged around the outer side of the central cylinder (102) and spliced to form a force transmission frame body;
wherein an inner side of the plurality of arc beams (4022) is provided with a arc-shaped slot (4031) having a conforming shape with the plurality of arc beams (4022);
wherein a plurality of rollers (4032) is provided in the arc-shaped slot (4031), and the plurality of rollers (4032) is in rolling contact with the outer cylindrical surface of the central cylinder (102);
wherein a plurality of buoyancy support assemblies is provided on an outer side of the plurality of arc beams (4022) at a top of the plurality of columns (4021) in a circumferential direction of the central cylinder (102).
