Description

Wave energy conversion system

The present invention relates to an energy conversion device, and more particularly to a wave energy conversion system for generating electricity by ocean wave energy.

Since the burning of petrochemical energy will cause global climate change, ozone hole and acid rain, the use of nuclear energy will cause thorny problems such as radiation leakage and nuclear waste. Therefore, countries have invested in renewable energy (eg solar power, ocean wave energy). The research field of power generation or geothermal power generation, etc., hopes to obtain endless sources of energy without damaging the environment. Among them, since the oceans account for 71% of the earth's area, and there is less and less space available on land, in order to prevent renewable energy equipment from competing with people, many marine countries have invested in the research and development of power generation equipment such as ocean waves, tides and currents. .

Please refer to FIG. 1 , for example, the new patent of the wave energy generation system of the Republic of China No. M401062, which discloses a conventional wave energy conversion system 9 comprising a body unit 91, a swing arm unit 92, a buoyancy unit 93 and The power unit 94 is coupled to a device A.

However, the conventional wave energy conversion system 9 generates high and low level differences by wave energy, and forms kinetic energy for rotating the rotating shaft 921, further driving the power generating unit 94 to generate electricity, since the rotating shaft 921 can only be fixed to drive the power generation according to the wave height difference. The unit 94 makes the power generation efficiency of the power generation unit 94 fixed. Therefore, the conventional wave energy conversion system 9 cannot adjust the power generation efficiency with the period of the wave, so that the power generation efficiency is not good. Furthermore, since the walrus conditions in the regions with strong wave energy are quite bad, the difference in height between the wave energy is quite large, but the difference in wave energy is too large to cause damage to the buoyancy unit 93. Therefore, the conventional wave energy conversion system 9 Not suitable for setting in areas with strong wave energy.

In summary, it is necessary to provide a wave energy conversion system that not only adjusts the power generation efficiency with the wave period, but also is suitable for setting in areas with strong wave energy.

The control module 3 is disposed on the casing 11 of the damper device 1 and is preferably disposed inside the casing 11 to prevent the control module 3 from being damaged by wave impact. The control module 3 includes a liquid amount adjusting component 31 and a processing unit 32.

Understand, I will not repeat them here. The processing unit 32 is composed of a device having wireless communication and numerical calculation functions, for example, a microprocessor having a wireless communication transceiver (Micro-processor) for storing programs and receiving "sea weather observation". The radio waves of the instrument (for example, floating stations at sea, submarine wave stations and offshore observation piles, etc.) to know the wave period of the position of the floating body 1 and to optimize the power generation efficiency according to the wave period, that is, The weight of the translation unit 12 of the damper device 1 and the damping coefficient of the power generation unit 2 are calculated.

Please refer to FIG. 3, which is a schematic diagram of a system of a second embodiment of the wave energy conversion system of the present invention, which comprises a damping device 4, a power generating unit 5 and a control module 6. The damper device 4 is provided with the power generating unit 5 and the control module 6. When the damper device 4 floats on the sea surface W, energy can be obtained by the waves to cause the power generating unit 5 to generate electric energy.

The damper device 4 includes a housing 41, a first chamber 42, a second chamber 43, a translating unit 44, an elastic member 45 and a liquid 46. The housing 41 is hollowed out by a rigid structure. The object is formed, for example, a floating tank that can carry weight and resist wave breaking force, so that the casing 41 can float on the sea surface W and be driven by wave energy on the sea surface W, for example: translation ( Surge) or lift (heave), etc. The interior of the housing 41 forms the first chamber 42 and the second chamber 43. The translation unit 44 is substantially the same as the translation unit 12 of the first embodiment, and the translation unit 44 can be omitted. The first chamber 42 is disposed in translation. The elastic member 45 is substantially the same as the elastic member 13 of the first embodiment. It is not described herein that the elastic member 45 is coupled between the inner wall surface of the housing 41 and the translating unit 44, so that the housing 41 is received by the housing 41. The translation unit 44 can linearly reciprocate when swung by force. The liquid 46 is received in the second chamber 43 to form a liquid coordinated damper (TLD). When the liquid 46 is swayed by control, the swing amplitude of the damper device 4 is increased to make the translation The amount of displacement of the unit 44 is increased to further increase the amount of power generated by the power generating unit 5. The damper device 4 can also be provided with a fixing component 47, which is substantially the same as the fixing component 14 of the first embodiment, and is not described herein. The embodiments are exemplified herein as follows, but are not limited thereto.

For example, the interior of the housing 41 of the damper device 4 is formed by a spacer 41a forming the first chamber 42 and the second chamber 43. The translation unit 44 is a square object having a pulley as an embodiment. The first housing chamber 42 is disposed in the first chamber 42 and is translatably disposed on the spacer 41a, and the translating unit 44 is provided with a chamber 441 for accommodating liquid such as seawater and keeping the liquid from swinging (Sloshing). A non-sloshing liquid L _{N is formed} to increase the weight of the translating unit 44. The elastic member 45 is coupled between the housing 41 and the translating unit 44. The stiffness or Elasticity of the elastic member 45 is positively correlated with the displacement of the translation unit 44. The liquid 46 is a liquid such as seawater. The liquid 46 is accommodated in the second chamber 43 and can be driven by an external force to form a swinging liquid L _S (Sloshing Liquid), so that the housing 41 and the liquid 46 are common. A liquid coordinated damper is formed, so that the liquid 46 can be coupled to the housing 41 via control to form a new characteristic frequency (Eigenfrequency) when the characteristic frequency and the wave period (Frequency of When the Ocean Wave is the same, the wave energy can be continuously input to the damper device 4, so that the liquid oscillating force of the liquid 46 becomes larger, and the displacement amount of the damper device 4 is increased, and the displacement amount of the reciprocating movement of the translation unit 44 is increased. The amount of power generation of the power generating unit 5 is increased. Wherein, the capacity or weight of the liquid 46 is positively correlated with the total weight of the damping device 4, and is positively correlated with the weight ratio of the translating unit 44 and the liquid 46, and the total weight or the weight ratio is positively correlated with the characteristic frequency. . The fixing assembly 47 includes a plurality of cables 471 in combination with a plurality of anchors 472 that are fixed to the seabed B.

The power generating unit 5 is substantially the same as the power generating unit 2 of the first embodiment, and is not described here. The power generating unit 5 is coupled between the housing 41 of the damper device 4 and the translating unit 44. When the translating unit 44 linearly reciprocates, the power generating unit 5 can generate power by linear telescopic movement.

The control module 6 includes a liquid amount adjusting component 61 and a processing unit 62. The liquid amount adjusting component 61 and the processing unit 62 are substantially the same as the liquid amount adjusting component 31 and the processing unit 32 of the first embodiment, respectively. I will not repeat them here. The liquid amount adjusting component 61 is connected to the translating unit 44 and the second chamber 43 of the damper device 1 for adjusting the liquid capacity (or weight) of the translating unit 44 and the second chamber 43; the processing unit 62 is electrically The liquid amount adjusting unit 61 and the power generating unit 5 are connected to each other.

Referring to FIG. 4, it is a flowchart of a control method of a second embodiment of the wave energy conversion system of the present invention, which comprises a reading step S1, a calculating step S2 and an adjusting step S3. The reading step S1 receives the wireless signal of the sea meteorological observation instrument from the control module 6, and obtains the wave period of the position of the floating body 1. In detail, the control module 6 receives the radio wave of the "sea meteorological observation instrument" for interpreting the wave period of the position of the damper device 4 and storing the wave period.

In the calculating step S2, the weight of the translation unit 44 and the liquid 46 is calculated by the control module 6 according to the wave period of the position of the floating body 1. In detail, since the weight of the liquid of the translating unit 44 and the second chamber 43 changes, the natural vibration frequency of the wave energy conversion system will be changed, and it is known from the conventional physical knowledge that when the wave When the period, phase, and external force of the natural vibration frequency of the conversion system are the same, the resonance effect (Resonant) will occur, resulting in an increase in the resultant force. Among them, phase control is not the focus of discussion in this case. I will not repeat them. Therefore, by controlling the natural vibration period of the wave energy conversion system, the displacement amount of the damper device 4 can be increased, and the power generation amount of the power generation unit 5 can be increased. Wherein, the ratio of the weight of the translating unit 44 to the total weight of the wave energy conversion system is preferably 15%, so that the translation unit 44 is closest to the natural resonance frequency of the wave energy conversion system, resulting in displacement of the floating body 1. The power generation unit 5 generates the best power generation efficiency. Therefore, the control module 6 calculates the liquid of the translation unit 44 and the second chamber 43 according to the change of the wave period of the position of the damping device 4 . The weight ratio of the liquid 46 is converted into the liquid of the translating unit 44 and the liquid of the second chamber 43 and the weight of the wave energy conversion system, so that the damping device 4 can generate a maximum displacement amount, so that the power generating unit 5 Maintain the situation of high power generation efficiency.

More specifically, since a liquid coordinated damper is formed in the damper device 4, coupling will occur, and a new characteristic period (Eigenfrequency) is generated, and the liquid of the translating unit 44 and the second volume The weight ratio of the liquid in the chamber 43 changes the natural vibration frequency. When the damper device 4 moves, the liquid level in the second chamber 43 will start to oscillate, and on the opposite wall surface of the second chamber 43 The water level is symmetrical. Therefore, when the damper device 4 generates a resonance effect with an external force, the generated liquid oscillating force will be much larger than the external force (for example, the force caused by the wave energy), and the liquid oscillating force is generated. The phenomenon that the resultant force of the external force increases, causing the liquid swinging force to coincide with the movement of the damper device 4, causing the displacement amount of the damper device 4 to become large.

In other words, since the wave energy is to be collected, it is necessary to let the wave force work on the wave energy conversion system. The energy obtained by the wave energy conversion system is the product of the wave force and the displacement amount. Therefore, if the wave energy conversion system and the wave force The resonance phenomenon is generated, so that the more energy can be obtained by the wave energy conversion system, the displacement amount of the wave energy conversion system is further increased, and at the same time, the displacement amount of the translation unit 44 is increased, and the power generation amount of the power generation unit 5 is increased.

For example, when the external force period changes, the total weight of the wave energy conversion system also needs to be changed. Therefore, the control module 6 can calculate the ratio of the swing frequency (ω _f ) of the liquid 46 to the external force frequency (ω _e ). And the ratio of the natural resonance frequency (ω ₂ ) of the wave energy conversion system to the external force frequency (ω _e ), and the relationship between the value of the external force period and (ω ₂ /ω _e )=1.1 to 1.2 when the external force period fluctuates. Calculate the natural resonance frequency (ω ₂ ) of the wave energy conversion system, calculate the total weight value of the wave energy conversion system at the optimal weight ratio, and calculate the relationship between (ω _f /ω _e )=2.1 to 2.3. The depth, capacity, weight, and the like of the liquid 46 enable the power generating unit 5 to achieve optimum power generation efficiency.

The adjusting step S3 is to adjust the weight of the translating unit 44 and the liquid 46 by the control module 3. In detail, since the damper device 4 floats on the sea surface W, if the weight of the translation unit 44 and the liquid 46 is changed in response to the wave period, the control module 3 can draw/discharge the seawater into the translation. The chamber 441 of the unit 44 and the second chamber 43 change the weight of the translating unit 44 and/or the liquid 46 to further increase the displacement of the wave energy conversion system, thereby increasing the displacement of the translating unit 44. The amount of power generated by the power generating unit 5 is increased. Wherein, when the total weight of the wave energy conversion system is increased, it is preferable to appropriately increase the damping coefficient of the power generating unit 5 by the control module 3 to maintain better power generation efficiency.

According to the foregoing technical means, the main feature of the second embodiment of the wave energy conversion system of the present invention is that a liquid coordinated damper is formed in the damper device 4, and when the damper device 4 and the external force generate a resonance effect, The displacement amount of the translation unit 44 is increased, and the power generation amount of the power generation unit 5 is increased, so that the power generation efficiency is improved by about 150%. Therefore, when the wave period is changed, the total weight and the weight ratio corresponding to the wave period can be calculated by the control module 6 to adjust the liquid capacity of the translation unit 44 and the second chamber 43. The power generation unit 5 is maintained at the highest power generation efficiency. Therefore, the wave energy conversion system of the present invention can achieve the effect of adjusting the power generation efficiency with different wave periods by adjusting the weight of the wave energy conversion system.

Furthermore, since the wave energy conversion system of the present invention uses the technical means of adjusting the weight, the damping device 4 and the liquid coordinated damper generate a resonance effect, so that the combined force of the liquid swing force and the wave energy increases. In addition, since the wave energy conversion system obtains the energy as the product of the external force and the displacement amount, if the wave energy conversion system is set in a region where the wave energy is strong, the more energy the wave energy conversion system can obtain, the more the generation The large displacement amount further increases the amount of power generated by the power generating unit 5. Therefore, the wave energy conversion system of the present invention has an effect suitable for being placed in an area where the wave energy is strong.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
