Description

Wave inertial power generation device

The invention relates to a power generation device, in particular to a wave inertial force power generation device.

With the improvement of environmental protection awareness, renewable energy has been paid attention to by the public. Among them, wind power generation accounts for a certain proportion of renewable energy. Generally, wind power generation devices use the wind generated by air flow to drive the fan blades to rotate, and the rotation of the fan blades further Drive generators to generate electricity. Generally speaking, offshore wind resources are more abundant than onshore resources, and the wind direction is more stable, so that offshore wind power can provide more and stable power than land wind power in the same period of time. However, compared with offshore wind power generation and land wind power generation, the construction cost and maintenance and repair costs of offshore wind power generation become the main cost of offshore wind power generation.

Please refer to Fig. 1, which is the patent number M599855 of the Republic of China, which illustrates a floater actuated two-way driving wave power generation device 11, which includes a pipe fitting 111, a floating body 112, a driving assembly 113, a mounting base 114, a connecting body 115, a base 116, and an antenna 117 , and battery 118, the floating body 112 floats on the water surface, the pipe fitting 111 passes through the floating body 112, the driving assembly 113 is arranged in the pipe fitting 111 to obtain the power to move up and down, and the mounting base 114 is provided with a power generation module (not shown in the figure) shown), the connecting body 115 is connected with the pipe fitting 111 and the floating body 112 to fix the pipe fitting 111 and can only move up and down, the base 116 has weight to sink into the water so that the pipe fitting 111 can stand upright on the water surface, the antenna 117 can send and receive signals externally, and the battery 118 The electric power generated by the power generation module can be stored, and the waves on the sea can drive the floating body 112 to move up and down, so that the pipe 111 can move up and down relative to the floating body 112, and drive the driving component 113 to obtain the power of the waves to further drive the power generation module generate electricity.

As can be seen from the above description, although the prior art discloses a wave power generation device, it still has the following disadvantages in actual use:

The conventional wave power generation technology cannot obtain the power of waves from the side to generate electricity.

2. Insufficient structural strength: In general wave power generation structures, because of the need to absorb the power of waves, a movable mechanism will be provided on the structure, such as the connecting body 115 that connects the pipe 111 and the floating body 112 in the prior art, so that the drive assembly in the pipe 111 113 obtains the power of waves, but the structure protruding from the outside of the floating body 112 will be impacted by external wind and waves. When strong winds and waves occur on the sea, the external structures will not be able to resist the impact of wind and waves and cause structural damage.

3. High cost and low power generation efficiency: Generally, a power generation device installed on the sea is usually a single unit as a power generation unit, and its power generation capacity is limited, and the power generated by the offshore power generation device needs to be transmitted to land, so a long power transmission line must be erected, and the construction cost of marine power generation equipment is expensive. Quite large, but the power obtained by the power grid on land is not a lot, so the disadvantage of poor power generation efficiency will occur.

4. Failure to protect the coastline: The known wave power generation device floats on the water surface and floats up and down with the height of the waves. It cannot resist the impact of the waves, and cannot be used as a wave dissipation block. There is no space for small fish to hide at the bottom, and it cannot provide a living environment for fish schools. , unable to protect the ecology and topography of the coastal waters.

At this time, the main body 31 The surrounding wall 33 on the right side pushes the mass body 41 in the right accommodating space 32 in the thrust direction 26 to the left, so that the main body 31 and the mass body 41 move away from the shore 22. When the main body 31 is fixed by the When the mass body 41 stops moving due to the restriction of the body 34, the mass body 41 will move to the left by inertial force relative to the body 31, and at the same time drive the vane 511 arranged at the lower power generation module 51 to rotate, and reach the second end 322.
