Figure 5 、 Figure 6 As shown, the inertial mass shell 02 is a cylindrical body. The inertial mass shell 02 is arranged on the periphery of the inertial mass body 01. The inertial mass body 01 is connected to the inertial mass shell 02. The inertial mass shell 02 is suitable for driving the inertial mass body 01 to swing. The inertial mass shell 02 is suitable for swinging relative to the outer floating body 06. When the inertial mass shell 02 swings back and forth or vibrates up and down relative to the outer floating body 06, it drives the third motor 53 and the fourth motor 54 to generate electricity. When the inertial mass shell 02 drives the inertial mass body 01 to swing left and right relative to the outer floating body 06, it drives the first motor 51 and the second motor 52 to generate electricity. The present invention provides a fully enclosed pendulum inertia-driven rope-traction wave energy power generation device, which is used to be placed on the sea surface. The outer floating body 06 absorbs energy from the waves in the directions of vertical and horizontal oscillation and pitching, generating multi-directional movements such as vertical oscillation, vertical oscillation, and pitching. The internal inertial mass shell 02 swings left and right and back and forth due to inertia. When the inertial mass shell 02 swings back and forth, it drives the third motor 53 and the fourth motor 54 to generate electricity. When the inertial mass shell 02 swings left and right due to inertia, it causes the inertial mass body 01 to swing left and right relative to the outer floating body 06, driving the first motor 51 and the second motor 52 to generate electricity. The present invention provides a fully enclosed pendulum inertia-driven rope-drawn wave energy power generation device. Since the inertial mass body 01 is connected to the inertial mass shell 02, the inertial mass shell 02 is suitable for swinging relative to the outer floating body 06.
