As shown in fig. 1-2, the present invention provides a wave energy collecting apparatus based on a sprocket driving pair and a guide sleeve pipe moving pair, comprising: a floating body 1, a sleeve 2, a conduit 3 and an anchor 5, wherein,
the floating body 1 is internally provided with a sealed cabin structure; the sleeve 2 is positioned at the center of the floating body 1, fixedly connected with the floating body 1 and penetrates out from the bottom of the floating body 1; a catheter 3, said catheter 3 moving within said cannula 2; the anchor 5 is connected with the bottom end of the conduit 3, and as shown in this embodiment, the conduit 3 is hinged on the upper surface of the anchor 5 through a spherical hinge pair 4, and further includes: the fixed chain wheel 7, the movable chain wheel 20, the chain 9, the hydraulic cylinder 15 and the hydraulic energy storage module 21, wherein,
