In the embodiment, as shown in fig. 1, the wave energy utilization assembly 2 comprises a cone 23, the cone 23 is provided with an inclined generatrix, and the cone 23 is provided with an inclined side surface; the cone cylinder 23 is fixed on the outermost side of the wave energy utilization component 2, namely the inclined side surface of the cone cylinder 23 is the outermost side of the whole floating wave energy power generation device, so that the waterline area generated at the draught position of the device in a semi-submerged floating state is the cross-sectional area of the cone cylinder 23 at the draught position, one end of the cone cylinder 23 is immersed under the water surface, and the other end of the cone cylinder 23 is positioned on the water surface, so that the cone cylinder 23 increases the waterline area of the device and the damping of the heaving of the device.
Specifically, the cone tube 23 has inclined side surfaces, on one hand, compared with vertical side surfaces, the inclined side surfaces can enable the cone tube 23 to improve the area of a water plane in a semi-submerged floating state, that is, the device is submerged and floated at the same position, the area of the water plane in the embodiment is larger, that is, the contact area between the floating type wave energy power generation device and the water surface is larger, so that the shaking of the cone tube 23 and the whole floating type wave energy power generation device is smaller (or less prone to shaking), the whole floating type wave energy power generation device is less prone to being turned over, and the stability of the device is improved; on the other hand, when the whole floating wave power generation device is subjected to fluctuation of heaving (heaving, which refers to vibration from water waves in the vertical direction), water flows along the inclined side surface of the cone tube 23, so that impact generated by heaving has a horizontal component effect, and thus the impact generated by heaving is buffered, and the inclined side surface also increases the coverage area in the vertical direction, so that the impact generated by heaving can be reduced, and thus the heaving resistance is improved.
Furthermore, the cone cylinder 23 is used as a component of the wave energy utilization assembly 2, and the cone cylinder 23 has the capabilities of improving the stability of the floating wave energy power generation device and increasing the heaving resistance, so that other structures for improving the stability of the whole floating wave energy power generation device are not needed, the structural complexity and the consumable materials of the device are reduced, and the cost is saved.
In this embodiment, the wave energy utilization assembly 2 further includes a top plate 22, the top plate 22 is fixedly connected to the outer wall of the buoy 1 and seals one end of the cone cylinder 23 located on the water surface, an air chamber 25 is formed by the top plate 22, the cone cylinder 23 and the outer wall of the buoy 1, an air hole 221 is formed in the top plate 22, the air hole 221 is connected to the air turbine generator 21, the wave energy drives the liquid level in the air chamber 25 to rise or fall, the liquid level in the air chamber 25 rises or falls to drive the gas in the air chamber 25 to flow out or in, and the gas in the air chamber 25 flows out or flows into the air turbine generator 21 to operate.
In the present embodiment, the wave energy utilization assembly 2 specifically acquires wave energy as follows:
as shown in fig. 1, when the conical cylinder 23 is not closed by the top plate 22, both ends of the conical cylinder 23 are in a penetrating state, after the conical cylinder 23 is closed by the top plate 22, only one end of the conical cylinder 23 which is positioned below the water surface is in a penetrating state, and liquid can enter the air chamber 25 through the end of the conical cylinder 23 which is positioned below the water surface; on one hand, when waves move to the floating type wave energy power generation device, the liquid level of the position of the floating type wave energy power generation device is raised by the waves, so that the liquid level in the air chamber 25 is raised, the air in the air chamber 25 is pushed by the rising of the liquid level in the air chamber 25 to flow out of the air holes 221, the air flow flowing out of the air holes 221 drives the air turbine generator 21 to work, the air turbine generator 21 converts mechanical energy into electric energy, and the purpose of generating electricity by utilizing wave energy is achieved; on the other hand, when the waves leave the floating type wave energy power generation device, the liquid level of the position of the floating type wave energy power generation device is lowered, so that the liquid level in the air chamber 25 is lowered, vacuum (or under-pressure) is formed in the air chamber 25, air is sucked and enters the air chamber 25 through the air turbine generator 21 and the air holes 221 in sequence, airflow generated by the air sucked and sucked by the air chamber 25 drives the air turbine generator 21 to work, the air turbine generator 21 converts mechanical energy into electric energy, and the purpose of generating electricity by utilizing wave energy can be achieved.
It should be noted that, when waves enter the floating type wave energy power generation device, air in the air chamber 25 can flow out, when the waves leave the floating type wave energy power generation device, air flows in the air chamber 25, and the air flows all pass through the air turbine generator 21, but the conventional air turbine generator 21 can only utilize the air flow in one direction, so that the utilization rate of wave energy is low, so that the air turbine generator 21 can be selected as a bidirectional air turbine generator which can keep unidirectional rotation under the action of air flows in different directions, so that the directions of voltage potentials generated by the air turbine generator 21 are kept consistent, for example, a Chinese patent with the publication number "CN 212337525U" discloses a radial flow type air turbine device for an oscillating water column wave energy power generation device, and for example, a Chinese patent with the publication number "CN 207420785U" uses a bidirectional air turbine for a single-pile type wind energy-integrated wave energy power generation system suitable for offshore The specific structure of the electric machine, and thus the bidirectional air turbine generator, is known to those skilled in the art and, therefore, will not be described in greater detail in this specification.
In this embodiment, the small diameter end of the cone 23 is located on the water surface, and the top plate 22 closes the small diameter end of the cone 23; the large-diameter end of the cone 23 is positioned below the water surface; in combination with the above, the pressure difference of the air flowing inside and outside the air chamber 25 can be effectively increased, and the effect is benefited by the specific arrangement of the cone 23.
Specifically, the small-diameter end of the cone 23 is located above the water surface, the large-diameter end is located below the water surface, when waves enter the floating wave power generation device, the liquid level in the air chamber 25 rises, so that the air in the air chamber 25 can be rapidly compressed to a low volume state, and the pressure difference of the air flowing out of the air chamber 25 is improved (the air pressure in the air chamber 25 is greater than the air pressure outside the air chamber 25); when waves leave the floating wave power generation device, the liquid level in the air chamber 25 is reduced, so that a vacuum (or under-pressure) space with a larger space can be quickly formed in the air chamber 25, and the pressure difference of air flowing into the air chamber 25 is increased (the air pressure outside the air chamber 25 is higher than the air pressure in the air chamber 25).
Of course, according to actual conditions, the small-diameter end of the cone 23 can be located below the water surface, and the large-diameter end of the cone 23 is located above the water surface, so that the arrangement of the cone 23 can also achieve the effects of improving the stability of the floating wave power generation device and increasing heave damping, and only the effect of the pressure difference of the internal and external flows of the gas in the gas chamber 25 is not good as the effect of the arrangement mode of the cone 23.
