New energy hybrid power generation device and using method

The invention discloses a new energy hybrid power generation device which comprises fixing rod pieces, a floating plate and a base plate. The fixing rod pieces comprise a first fixing rod, a second fixing rod, a third fixing rod and a fourth fixing rod, and the first fixing rod, the second fixing rod, the third fixing rod and the fourth fixing rod are distributed on the periphery of the floating plate in a cross shape; and the floating plate is slidably connected with the first fixing rod, the second fixing rod, the third fixing rod and the fourth fixing rod. A first wave power generation assembly is arranged on the floating plate, the floating plate floats on the sea surface due to the buoyancy of the floating plate, and fan blades above the floating plate can conduct wind power generation under the condition that wind exists; and meanwhile, according to the wind direction, a first motor drives the floating plate to rotate, the fan blades are matched with the wind direction, and the power generation efficien
