[0049] The specific application of the detachable anchor winch applied to the floating wind power platform will be described below, including the lifting anchor chain step, the dismounting sprocket assembly and rocker assembly step, and the dismounting hydraulic pump station step.
[0050] The lifting anchor chain step: in combination with Figures 1 to 4 It is understood that the chain wheel assembly 200 and the rocker assembly 300 are used to lift the anchor chain 500, wherein the pawl oil cylinder 331 drives the pawl 332 to press against the corresponding anchor chain 500, the brake vane 121 is rotated to be in the open state, the rocker oil cylinder 321 drives the pawl 332 to stretch the anchor chain 500; the brake vane 121 is rotated to be in the closed state, the pawl 332 is loosened, and the pawl 332 and the rocker 322 are reset; the above steps are repeated until the tension of the anchor chain 500 is adjusted, and the positioning of the floating wind power platform is completed.
