[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 6As shown, a fully enclosed crank-connecting rod inertia-driven wave energy power generation device of the present invention comprises a shell, a bracket 01 arranged in the shell, an inertial mass body 02, a force transmission rod 03, an eccentric circle 04, and a generator 05. The shell is a closed body, and the shell and the bracket 01 are connected as a whole. The inertial mass body 02 is a solid object, and the bottom of the inertial mass body 02 is connected to the bracket 01 through a reset member. The inertial mass body 02 is suitable for moving up and down relative to the bracket 01. The axial direction of the force transmission rod 03 is perpendicular to the moving direction of the inertial mass body 02. The inertial mass body 02 is connected to the force transmission rod 03. One end of the eccentric circle 04 is rotatably connected to the force transmission rod 03, and the other end is connected to the driving end of the generator 05. When the inertial mass body 02 moves up and down relative to the bracket 01, the eccentric circle 04 is driven to swing relative to the force transmission rod 03, thereby driving the generator 05 to generate electricity. The fully enclosed crank-connecting rod inertia-driven wave energy power generation device of the present invention floats on the sea surface when working. With the impact and shaking of waves, the shell mainly produces movements in four directions: transverse swing, longitudinal swing, heave swing and bow swing. The largest component of the energy generated by the waves is the component in the vertical direction. This component causes the shell to produce heave swing motion. When the floating body swings heave, the inertial mass body 02 produces reciprocating motion in the heave direction relative to the bracket 01, forcing the eccentric circle 04 above to rotate and drive the generator 05 to generate electricity, thereby realizing the conversion of wave energy into electrical energy. When the inertial mass body 02 produces reciprocating motion in the heave direction, the eccentric circle 04 continues to rotate, so that the generator 05 continues to generate electricity. The invention discloses a fully enclosed crank-connecting rod inertia-driven wave energy power generation device. The device comprises a shell, which is a closed body. A bracket 01, an inertial mass body 02, a force transmission rod 03, an eccentric circle 04, and a generator 05 are all arranged in the shell. Therefore, the entire device can be suspended on the sea surface for operation or fixed on the seabed for operation. The device is not limited by the depth of the sea area, has a wider application range, and makes up for the defects of the current wave energy power generation device that is susceptible to seawater corrosion and has poor reliability. The device has higher power generation stability. At the same time, since the bottom of the inertial mass body 02 is connected to the bracket 01 through a reset member, the inertial mass body 02 is suitable for moving up and down relative to the bracket 01. When the inertial mass body 02 moves up and down relative to the bracket 01, the eccentric circle 04 is driven to swing relative to the force transmission rod 03, thereby driving the generator 05 to generate electricity. Since the maximum capture gain of wave energy lies in the heave direction, the device of the invention can generate a component in the vertical direction as long as waves are generated, so that the shell generates heave. Therefore, the device of the invention can utilize energy generated by waves in multiple directions. Compared with other existing wave energy power generation devices, the wave energy power generation device collects more total energy, thereby improving the utilization rate of wave energy.

[0021] Alternatively, if Figure 5As shown, it also includes a driving connecting rod 07, one end of which is connected to the force transmission rod 03 and the other end is connected to the inertial mass body 02, and the driving connecting rod 07 is suitable for rotating relative to the inertial mass body 02. When the inertial mass body 02 moves up and down relative to the bracket 01, the driving connecting rod 07 drives the eccentric circle 04 to swing relative to the force transmission rod 03.

[0022] Optionally, two eccentric circles 04, generators 05, and driving connecting rods 07 are provided, and the two eccentric circles 04 are respectively connected to the two ends of the force transmission rod 03 along the length direction, and the two eccentric circles 04 are respectively connected to the driving end of a generator 05, and the connection points of the two driving connecting rods 07 and the force transmission rod 03 are respectively located at the two ends of the force transmission rod 03 along the length direction, and the connection points of the two driving connecting rods 07 and the inertial mass body 02 are located on both sides of the inertial mass body 02, and the two driving connecting rods 07 are parallel to each other. Two eccentric circles 04, generators 05, and driving connecting rods 07 are each provided, so that the power generation of the device of the present invention is increased.

[0023] Alternatively, if Figure 4 As shown, it also includes a limiting slide rail 06 and a limiting rod 08. Two limiting rod holes 61 are provided on the limiting slide rail 06. The two limiting rod holes 61 are both arranged along the length direction of the limiting slide rail 06. The bracket 01 includes a first mounting plate 11. The plane where the first mounting plate 11 is located is perpendicular to the moving direction of the inertial mass body 02. The limiting slide rail 06 is connected to the first mounting plate 11. The inertial mass body 02 is arranged in the limiting slide rail 06. The axial direction of the limiting rod 08 is perpendicular to the axial direction of the inertial mass body 02. The limiting rod 08 passes through the inertial mass body 02 and is rotatably connected to the inertial mass body 02 through a bearing. The two ends of the limiting rod 08 respectively pass through a limiting rod hole 61, and the ends of the two driving connecting rods 07 connected to the inertial mass body 02 are respectively connected to the two ends of the limiting rod 08. When the inertial mass body 02 moves relative to the limiting slide rail 06, the limiting rod 08 moves up and down in the limiting rod hole 61. By providing the limiting slide rail 06 and the limiting rod 08, the moving direction of the inertial mass body 02 relative to the bracket 01 is limited, thereby further improving the power generation of the device of the present invention.

[0024] Optionally, the inertial mass body 02 is a cylinder, and the limiting slide rail 06 is cylindrical.

[0025] Optionally, the bracket 01 also includes a second mounting plate 12, a third mounting plate 13, and a plurality of connecting rods 14. The second mounting plate 12 and the third mounting plate 13 are respectively located on the upper and lower sides of the first mounting plate 11. The first mounting plate 11, the second mounting plate 12, and the third mounting plate 13 are parallel to each other. A plurality of connecting rods 14 connect the first mounting plate 11, the second mounting plate 12, and the third mounting plate 13. The generator 05 is arranged on the second mounting plate 12, so that the device of the present invention has a more compact structure and stronger stability.

[0026] Optionally, the reset member is a return spring 09, one end of which is connected to the third mounting plate 13, and the other end is connected to the bottom of the inertial mass body 02. Specifically, the inertial mass body 02 includes a main body, a connecting column, and a mounting plate arranged in sequence from top to bottom, the return spring 09 is sleeved on the connecting column, and the inertial mass body 02 is connected to the third mounting plate 13 through the mounting plate. With the assistance of the return spring 09, the generator 05 can continuously rotate and generate electricity, the energy utilization efficiency is highly improved, and the return springs of different stiffness can be replaced to adapt to different sea conditions, and the working reliability is high.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
