Description

Wave power generation device

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

Electricity generation generally refers to the process of converting other types of energy into electricity. In the power system, the electric energy generated by power generation is transmitted to users or energy storage systems through the transmission system and distribution system.

However, according to different energy sources, current power generation methods are divided into the following types: nuclear power generation, thermal power generation, geothermal power generation, hydropower generation, solar power generation, biomass power generation, wind power generation, etc.

According to information released by Taiwan Electric Power Company, the power generation of Taiwan Power System in 2010 was 248.81 billion kilowatt-hours, of which thermal power generation accounted for 79.6%, including 35.5% coal-fired, 1.6% oil-fired, 42.5% gas-fired, and 2.1% steam-electricity symbiosis. % (excluding garbage and methane), etc., the proportion of renewable energy is 6.3% (including garbage and methane in water power and steam and electricity symbiosis), pumped water power is 1.3%, and nuclear energy is 10.8%.

It can be known that the main power generation method in Taiwan currently is thermal power generation. Thermal power generation takes large-capacity steam turbine units as an example. The power generation principle is to use the steam cycle method to convert fossil fuels (coal, heavy oil, natural gas) Chemical energy generates thermal energy through combustion reactions. The boiler water is heated in the boiler furnace to generate high-temperature and high-pressure steam, which then drives the steam turbine and turns it into rotating mechanical energy. Finally, the mechanical energy is converted into electrical energy through the generator. (or electricity), transported to various places.

However, although thermal power generation is the main source of power supply, it is most likely to cause environmental pollution. Burning coal, heavy oil and natural gas will produce a certain amount of carbon dioxide and waste gas. In addition to causing acid rain, large amounts of carbon dioxide and waste gas are also responsible for global warming and the greenhouse effect. The discharge of heated water into the sea will also have a serious impact on the marine ecological environment.

With the current rise in environmental awareness and the exhaustion of fossil fuels, renewable energy power generation methods are gradually receiving attention, such as hydropower, solar power, and wind power. At present, Taiwan's renewable energy power generation accounts for the highest proportion of hydropower. In order to expand the promotion of renewable energy, the government has set a policy goal of 20% of renewable energy power generation in 2025. It is now actively promoting solar photovoltaic and wind power generation. It is expected that the capacity of solar photovoltaic installations will reach 20GW in 2025, and the capacity of offshore wind power installations will reach more than 5.7GW.

However, although wind power generation has the characteristics of high efficiency, high power density and low pollution (no fuel cost, no waste gas and its treatment cost). But in reality, the power generated by wind turbines varies with weather conditions and wind speed.

Because the wind in many areas of Taiwan is intermittent, the wind speed (must be greater than 5 meters/second) cannot be maintained at a constant value, resulting in an unstable wind energy source. In addition, large-scale wind power generation requires a large amount of land to build wind farms so that it can produce a relatively large amount of energy. It can be seen that the demand and selection of the site are extremely important.

Moreover, it is known that wind turbines still have room to expand the collection and utilization of wind energy in wind farms. In order to make the wind energy in wind farms more effective and improve power generation efficiency, for this reason, the structure of wind turbines Improvement is a problem that those in the technical field must solve.

Conventional wind turbines are used because the wind source is intermittent and the wind speed (must be greater than 5 meters/second) cannot maintain a constant value, resulting in an unstable wind energy source.

Among them, please refer to Figure 1B, which is a schematic structural diagram of a first power generation module according to an embodiment of the present invention.

Among them, the above-mentioned first pivot member 1624 and the second pivot member 1644 use sleeve shafts, miniature bearings or ball bearings, but this embodiment is not limited to the use of the above-mentioned bearings.

Among them, the above-mentioned first power generation module 40 and the second power generation module 40A use iron-core permanent magnet generators or traditional permanent magnet generators.

Among them, the iron-core motor adopts iron-core coil, carbon brush, non-magnetic damping, and rare earth permanent magnet electric technology, which changes the traditional motor using silicon steel sheet and winding stator structure. Combined with electronic intelligent frequency conversion technology, the motor system The efficiency is increased to more than 95%. Compared with the traditional radial magnetic field structure design, the axial magnetic field structure design is adopted, which greatly improves the power density and torque volume ratio, and adopts new winding technology, high-pressure precision die-casting and polymer materials. , effectively reducing winding copper losses. Furthermore, because silicon steel sheets are not used as stator and rotor core materials, magnetic damping and iron losses are eliminated, driving power is reduced, and iron loss heat sources are reduced.

In addition, the above-mentioned traditional permanent magnet generator can also be called a permanent magnet synchronous motor or a permanent-magnet synchronous servo motor (PMSM). It refers to a synchronous motor whose rotor uses permanent magnets instead of windings. It is further divided into surface permanent magnet (SPM) motor and built-in permanent magnet (IPM) motor. Permanent magnet synchronous motor can be divided into radial, axial or transverse (transverse) according to the magnetic flux mode. According to its components Depending on the layout, various permanent magnet synchronous motors have different performances in efficiency, volume, weight and working speed.

Among them, the surface permanent magnet motor has a simpler structure. The magnets are glued or fixed on the surface of the rotor. Therefore, there is a wide air gap between the rotor and the stator without magnets. The magnetic permeability of the magnets is equivalent to that of air, so the rotor The saliency is very small and can be omitted. A larger air gap also weakens the armature effect of the rotor, so its inductance Ld is very small, which also affects the stator time constant of the surface permanent magnet motor.

Furthermore, the built-in permanent magnet motor means that the magnets of the permanent magnet motor are buried in the rotor. The magnets can be protected by the rotor and there will be no problem of magnets falling off during high-speed operation. However, the rotor needs to have a cavity where the magnets should be placed. The rotor is made of silicon steel, and its magnetic permeability is much higher than that of the magnet. Therefore, the magnet part can be regarded as an additional air gap. The air gap between the rotor and the stator will change periodically, which is the salient pole effect, and the torque generated thereby It contains reluctance torque component and its efficiency is higher.

At the same time, the first driving shaft 30A guides the crank pin 22 to move, causing the crankshaft 20 to rotate and driving the first power generation module 40 to rotate. Generate electricity.

Furthermore, in this embodiment, when the second power generation module 40A and the first power generation module are disposed on the first crankshaft 24 and the second crankshaft 26 at the same time, the second power generation module 40A is also The crankshaft 20 will be driven to operate together due to the rotation of the crankshaft 20, causing the second power generation module 40A to rotate to generate electric power.

The advantage of this embodiment is that the linkage structure of the fan blades 30 and the crankshaft 20 of the wave power generation device can match the wind direction of the wind field, so that the wind energy can be more effectively utilized and the power generation efficiency can be improved, so that the fan blades can be used The linkage structure between 30 and the crankshaft 20 allows the fan blade 30 of the wave power generation device to swing as the wind direction changes, maximizing the source of wind power to generate electrical energy.

Next, please refer to Figure 3, which is a schematic structural diagram of another embodiment of the present invention. As shown in the figure, this embodiment uses the same components as the previous embodiment, namely the base 10, the The crankshaft 20 , the fan blade 30 and the first power generation module 40 are further provided with a hydraulic drive module 50 in this embodiment.

In this embodiment, the hydraulic drive module 50 includes a drive shaft assembly 52 and a hydraulic drive device 54 .

The drive shaft assembly 52 includes a second drive shaft 521, a first crank member 523, a third drive shaft 525 and a second crank member 527. One end of the second drive shaft 521 is pivotally connected to the first crank member 527. Drive shaft 30A, the other end of the second drive shaft 521 is pivotally connected to one end of the first crank member 523, the other end of the first crank member 523 is pivotally connected to one end of the third drive shaft 525, the third drive shaft The other end of 525 is pivotally connected to one end of the second crank component 527. Further, the intersection point of a first crank part 523A and a second crank part 523B of the first crank component 523 is pivotally connected to a pivot joint of the base. On seat 11.

The handle body 543 The ring is provided on one side of the motor 541, the piston part 545 is inserted into the motor 541, the handle body 543 is pivotally connected to the other end of the second crank element 523A, and one end of the piston part 545 is pivotally connected to the The intersection of a first handle portion 527A and a second handle portion 527B of the second crank element 527.

Next, please refer to Figure 4, which is a schematic diagram of the operation state of another embodiment of the present invention. Here, the following practical example is given to illustrate the operation schematic diagram of the actual use of the wave power generation device of this embodiment. .

As shown in Figure 4, when the wind 90 blows towards the wave power generation device of this embodiment, the fan blade 30 rotates according to the wind direction of the wind 90. When the fan blade 30 rotates, the third fan blade 30 rotates. The three connecting members 38 pull the pivotally connected first driving shaft 30A to move. At the same time, the first driving shaft 30A guides the crank pin 22 to move, causing the crankshaft 20 to rotate and driving the first power generation module 40 to rotate. Generate electricity.

Furthermore, in this embodiment, the wave power generation device can be installed on flat land containing groundwater. When the second power generation module 40A and the first power generation module are simultaneously installed on the first crankshaft 24 and the second When the crankshaft 26 is turned, the second power generation module 40A will also be driven to operate together due to the rotation of the crankshaft 20, causing the second power generation module 40A to rotate to generate electric power.

And when the rotation of the crankshaft 20 drives the crankpin 22 to rotate the first crankshaft handle 24 and the second crankshaft handle 26, and drives the first power generation module 40 and the second power generation module 40A to rotate to generate electric power. , the first driving shaft 30A drives the second driving shaft 521 to move, and pulls the first crank element 523 to move.

Then the first crank element 523 drives the third driving shaft 525 to move, so that the second crank element 527 connected to the other end of the third driving shaft 525 is driven to reciprocate up and down, and the second crank element 527 When reciprocating up and down, the piston part 545 of the hydraulic driving device 54 is pulled to move up and down, thereby extracting groundwater through the hydraulic driving device 54 and taking out the groundwater for use by the user.

That is to say, the wave wind turbine not only provides users with sufficient power through wind power generation, but also can pull the hydraulic drive module 54 through the drive shaft set 52 on one side of the wave wind turbine, so that The hydraulic drive module 54 obtains groundwater through the traction of the drive shaft group 52, allowing users to use water conveniently.

At the same time, when the wind 90 stops, or the wind field is in a low wind volume state, the wave power generation device cannot generate electricity through wind resistance, so the hydraulic drive module 50 can be used to generate water power through the hydraulic drive module 50 . The hydraulic driving device 54 pulls the piston part 545 to move up and down, driving the second crank member 527 to move axially, and at the same time drives the third drive shaft 525 to move, and pulls the first crank member 523 to move, and also causes the third drive shaft 525 to move. The second driving shaft 521 drives the first driving shaft 30A to move. The first driving shaft 30A therefore drives the crank pin 22 to rotate. Due to the rotation of the crank pin 22, the crankshaft 20 moves and drives the first power generator. The module 40 or the second power generation module 40A rotates to generate electric power.

The advantage of this embodiment is that the wave power generation device drives the hydraulic drive module 54 to extract the underground water source through the drive shaft group 52, allowing the user to obtain the underground water source without external force.

The present invention can also install the wave wind power generation device at the waterside or streamside, but is not limited to this. The second crank element 527 of the driving shaft group 52 is driven by hydraulic drive to produce axial movement, and at the same time, The third driving shaft 525 is connected and pulls the first crank element 523 to move, and the second driving shaft 521 is also connected to drive the first driving shaft 30A to move. The first driving shaft 30A therefore drives the crank pin 22 Rotation occurs, and the crankshaft 20 moves due to the rotation of the crank pin 22, which drives the first power generation module 40 or the second power generation module 40A to rotate to generate electric power.

In the embodiments described above, the present invention is a wave-type wind power generation device, which can match the wind direction of the wind field through the linkage structure of the fan blade 30 and the crankshaft 20, so that wind energy can be more effectively utilized and enhanced. The power generation efficiency allows the fan blade 30 of the wave power generation device to swing as the wind direction changes through the linkage structure of the fan blade 30 and the crankshaft 20, maximizing the source of wind power to generate electrical energy. The swing of the fan blade 30 drives the drive shaft group 52 to pull the hydraulic drive module 54 to extract the underground water source, so that the user can obtain electricity and water sources through the wave wind power generation device at the same time, so that the wave power generation device can be used for maximum efficiency. .
