Description

Energy-enhanced wind power system

Technical field

The invention relates to a wind power generation system, in particular to a high-efficiency wind power generation system, wherein the wind power generation system can absorb wind energy in a full range and can effectively convert the absorbed wind energy into electric energy, and does not Harm the environment.

Background technique

The most traditional way to get electricity is to burn fossil fuels. However, fossil fuels release greenhouse gases during combustion, which seriously affects global climate changes and pollutes the environment. Power generation through wind power (a renewable energy source) not only avoids these problems, but also saves non-renewable resources. In addition, compared with nuclear power generation, hydropower, and thermal power generation systems, wind power generation systems are the most economical in terms of project cost and floor space.

The global wind energy reserves are very large, and theoretically 1% of wind energy can meet the needs of human energy. However, from the perspective of existing wind power generation systems at home and abroad, these wind turbines do not have innovative omni-directional energizers and other devices for capturing wind energy in all directions. That is to say, the power generation efficiency of existing wind turbines is quite low.

Generally, the wind turbine is a synchronous generator and is arranged on a vertical shaft. When the blades are rotated by the wind energy, electrical energy begins to occur. However, when the wind blows the traditional blades, the blades can absorb less than 30% of the wind energy. More than 70% of the wind energy has slipped away from the blades of the generator before it has worked. What is more serious is that the remaining wind energy left on the rotating blades due to the turbulence of the airflow, so the mutual elimination of the wind consumes a large part of the energy. Therefore, low efficiency and low wind speed power generation are a fatal weakness of traditional wind power generation systems.

In order to overcome the above drawbacks, a lot of improvements have been made to the conventional wind power generation system. Some people have used methods to increase the height of the tower, increase the length of the blades, and increase the power of the generator. However, these methods make the wind power generation system bulky and costly.

In theory, when the wind speed reaches 14m/s, this is the best time to use wind energy to generate electricity. However, wind speeds are more likely to destroy wind turbines. In order to avoid the destruction of the leaf, many blades have been artificially wound, rolled, and slurried to reduce the wind area on the blade, which greatly reduces power generation. the amount. What's more, in order to protect wild birds and so on, to avoid the damage of wind turbine blades to birds, some countries or regions almost prohibit the use of traditional wind turbines in certain seasons.

Therefore, in order to achieve sustainable development of renewable resources, it is necessary to develop a new wind power system that is highly efficient, energetic, and most effective in converting absorbed wind energy into electrical energy without harming wild birds.

Referring to Figures 1 and 2, in accordance with the illustrated embodiment, the present invention provides an energetic wind power generation system including a vertical shaft 10, a wind turbine 20, and the blades 22 in the body 21 of the generator 20 are rotatably Mounted on the vertical shaft 10, a plurality of generator blades 22 extend radially from the body 21.

As with conventional wind turbines, regardless of when the airflow acts on the blades 22, the blades 22 of the generator 20 rotate relative to the vertical shaft 10 to convert the absorbed wind energy into electrical energy.

Referring to Figures 1 and 3, the wind power generation system of the present invention further includes a wind catching device 3 installed around the wind power generator 20, wherein the wind catching device 3 includes an omnidirectional energy booster 31, the energizer 31 The utility model comprises four suction passages 32 respectively covering four orientations and arranged side by side, wherein each suction passage 32 has an air inlet 321 , an air outlet 322 , and a connecting air inlet 321 and an air outlet 322 and gradually The air inlet 323 is used to capture the outside wind, and the air outlet 322 is connected to the air vane 22. The high pressure generated by each air chamber 323 presses the wind energy absorbed by each air suction passage 32 through the air outlet 322. The blades 22 are used to drive the blades 22 to rotate to convert the absorbed wind energy into electrical energy most efficiently.

According to a preferred embodiment of the invention, the wind catching device 3 is adapted to capture wind energy from various orientations to the greatest extent. The wind catching device 3 includes four suction passages 32 covering four directions, namely, east, south, west, and north, wherein each of the suction passages 32 is an eccentric horn passage, so that each air outlet 322 is respectively associated with the wind. The leaves 22 are adjacent to each other, and each of the air inlets 321 and the air outlets 322 are eccentric flares, wherein the air inlets 321 extend radially outward from the air outlets 322. As a result, when the wind energy blows through the suction passage 32 which is greatly reduced, the wind energy reaching the air outlet 322 is increased by the eccentric guiding structure, so that the wind energy becomes a high pressure wind force and only acts. On a specific part of the fan blade 22 on one side. In other words, the eccentric guiding structure, on the one hand, makes the wind become a high-pressure wind, and on the other hand, the high-pressure wind acts only on a specific part of the blade 22, effectively ensuring that the blade 22 of the generator 20 can only be counterclockwise or compliant. The strong rotation of the hour hand direction is the most effective in converting the absorbed wind energy into electrical energy.

Therefore, no matter whether the wind can be blown from any direction in the east, south, west, north, or 360 degrees, such as the wind blowing from the east or the south, at least one suction channel 32 in the east or south will capture the wind energy to a certain extent. . When the captured wind energy flows through the eccentric and gradually decreasing suction passage 32, the wind energy blown from the air outlet 322 It becomes a high-pressure and powerful wind, where the high-pressure wind energy is twice the wind energy at the inlet 321 . The wind catching device of the present invention not only increases the wind speed V but also increases the wind receiving area A and the air density p. According to the following equation:

W=l/2 PV ³ A

It can be clearly seen that the magnitude of wind energy is proportional to the area through which the airflow passes, the density of the air, and the cube of the airflow velocity. The doubling of the wind speed can increase the output of the wind turbine by eight times. In other words, as long as the wind speed can be twice that of the air inlet 321 , the power of the wind turbine will be eight times the original.

As shown in Figures 1 and 2, the illustrated wind power generation system further includes a set of batteries 40 electrically coupled to the generator 20 for storing electrical energy. Therefore, when each of the suction passages 32 captures wind energy from different directions, the wind energy is pressed into the eccentric and gradually decreasing wind chamber 323, and then pressed from the air outlet 322 to a specific portion of the vane 22, thereby driving the wind. The rotor blades 22 of the generator are rotated relative to the vertical shaft 10 to efficiently convert the captured wind energy into electrical energy and store the generated electrical energy in the battery 40.

Referring to Figures 1 and 4, in accordance with the illustrated embodiment, the wind catching apparatus of the present invention further includes a windshield 33 mounted around the energizer 31 for increasing output power and increasing power generation. After the windshield 33 is used, the output power can be increased by increasing the wind receiving area without increasing the power of the generator, wherein the size of the windshield 33 matches the required power generation, and can be made into a circle. Or square.

Referring to Figure 1, in accordance with the illustrated embodiment, the energetic wind power system of the present invention further includes a light-controlled solar panel 50 for collecting solar energy, and a frame 60. The light-controlled solar panel 50 is used to absorb solar energy, convert the absorbed solar energy into electrical energy and store it in the battery 40, and the rack 60 securely locates the wind power generation system. The frame 60 is made of steel, aluminum alloy or stainless steel. The energizer 31 is preferably made of FRP, stainless steel, or engineering plastic.

As shown in Figs. 1 and 5, the wind catching device 3 is evenly divided into four sections for capturing wind energy from the east, south, west, and north directions. In other words, the wind catching device 3 is composed of four flared passages 32, wherein each of the flared suction passages 32 has a large flared air inlet 321 for capturing outside wind, a small flared air outlet. 322 is in communication with the vanes 22 for pressing the captured wind into the vanes 22. Therefore, the eccentric guiding structure of the flared suction passage 32 can increase the power of the wind energy.

As shown in Figures 1, 3, and 4, the present invention further includes a set of energy saving lamps 70, a controller 80, and a bird guard cover 90, wherein the bird guard cover 90 is made of stainless steel wire or mesh, through a plurality of The rivet is fixed on the air outlet 322, and the air outlet 322 is covered. It can only enter the wind, and cannot enter the bird, effectively avoiding harming the wild bird. It is to be noted that the windshield 33 may be composed of reinforced nylon, fiberglass, or the like, and is fixed to the periphery of the energizer 31 by a plurality of screws 300. Further, the wind turbine 20 is fabricated in accordance with the rated power and has a generator tail 211.

Further, the upper fixing plate 213 and the lower fixing plate 215 made of steel or aluminum alloy position the wind power generator 20 on the vertical shaft 10, and a plurality of rivet holes 214 are provided on the outer casing of the wind power generator 20 for installation. rivet. After the fixing screw 210 is inserted into the generator tail 211, the wind power generator 20 is fixed to the frame 60, wherein the fixing screw 210 is made of steel or aluminum alloy. The blades 22 of the wind turbine 20 are made of plastic, aluminum alloy, stainless steel or lightweight carbon fiber. Further, the wind power generator 20 is further fixed to the center of the frame 60 by the connecting member 220.

In addition, the wind power generation system of the present invention further comprises a plurality of combination bolts 26 made of high-strength steel for vertically or horizontally combining a plurality of wind power generation systems into a power generation network, which saves additional space and simplifies Installer.

Due to the eccentric guiding structure of the suction passage 32, the captured wind energy can act on a specific portion of the blade 22, i.e., a specific portion of the unilateral side of the blade 22. In other words, a particular portion of the unilateral side of the blade 22 will be a high pressure wind power source. On the other hand, other parts of the blade 22 are protected from wind. Therefore, there is no mutually offsetting wind force on the blades 22, which effectively ensures that the blades 22 of the generator 20 can only rotate strongly counterclockwise or clockwise. For example, the wind blows from the direction A, and after passing through the air inlet 321, the wind energy is pressed from the suction passage 32 into the blades 22 of the wind power generator 20, and at the same time, the blades 22 of the wind power generator 20 start to rotate. Convert the absorbed wind energy into electrical energy. If the wind blows from the 45° direction between D and C, the wind energy after the work is released from the suction passages 32 on the A and B sides. At this time, the air density and the wind speed at the air outlets 322 of the D and C faces are greatly increased.

For example, the wind speed of the natural wind is 3.5 m/s. If the omnipotent energy amplifier 31 is not installed, the wind speed at the air outlet 322 is also 3. 5 ra/s, and the density is only 50 W/m ² . The energizer 31, after the natural wind is absorbed by the air inlet 321 , is pressed to the air outlet 322 along the flared air chamber 323 and finally reaches the air duct 22 . Under the action of the eccentric guiding structure, the wind speed at the air outlet 322 is doubled, and the wind energy density is increased to 400 W/m ² . Therefore, the output of the wind turbine 20 is eight times that of the original.

The anilox lines shown in Figures 1 and 4 are bird guards 90, which are made of stainless steel wire or mesh having a mesh smaller than a bird. The rivet 93 is inserted into the rivet hole 214, and the bird guard cover 90 is fixed to the wind power generator 20, and the eccentric small horn air outlet 322 is covered, so that the bird does not fly into the air outlet 322. Referring to Figures 6 and 7, it can be seen that the energized wind turbine of the present invention can not only generate a single power, but also use a combination bolt 26 to vertically or horizontally connect a plurality of wind power generation systems to form a power generation grid. As shown in FIG. 6, a plurality of wind power generation systems are vertically combined on a roof or a floor by a combination bolt 26. As shown in Fig. 7, a plurality of wind power generation systems are horizontally combined between the building and the building by means of the combination bolts 26, or on the bridge.

As shown in FIG. 1, an integrated wind and solar hybrid system is illustrated, in which a light control solar panel 50, a set of batteries 40, a controller 80 are disposed on the top surface of the rack 60, and a bottom portion of the rack 60 is provided. There is a set of energy saving lamps 70 for light control. When it is dark, the energy-saving lamp 70 will automatically turn on. When it is bright, the energy-saving lamp 70 will automatically turn off. At this time, the solar-controlled solar panel 50 starts to receive solar energy, generates direct current and stores the current in the battery 40. However, when the rainy weather lasts for a long time, the power will not be enough, and the energy-saving lamp 70 will no longer be used. The present invention provides a special wind and solar hybrid system in which a solar panel 50 converts solar energy into electrical energy and a wind turbine 20 converts wind energy into electrical energy. Therefore, the light-controlled solar panel 50 and the wind turbine 20 of the present invention constitute an integrated wind-solar complementary system. The present invention can generate electricity during the day, and can generate electricity at night, and the more it is wind and rain, the easier it is to generate electricity. The wind-solar complementary system works by the following structure: first, each of the blades 22 of the wind turbine 20 is closely connected to the four eccentric horn air outlets 322 of the omnidirectional energy generator 31; second, the blades 22 pass The compression screw 217, and the compression plate 218 are firmly fixed to the main shaft 216 of the wind power generator. Therefore, when the blade 22 is driven by the strong wind, the high-speed rotation is performed centering on the main shaft 216 of the generator 20, and the magnetic lines of force are strongly cut during the rotation, thereby generating a strong current, and the battery 40 is charged by the controller 80. .

It will be apparent to those skilled in the art that the specific embodiments shown in the drawings are illustrative and not limiting.

The object of the invention will be fully and effectively achieved. The embodiments described above are intended to illustrate the functional and structural principles of the present invention and may be modified without departing from the principles of the invention.
