Description
Technical Field
[0001] The present invention relates to the technical field of wind power generation, and particularly relates to a novel wind power generation device and components. Background Art
[0002] Wind power generation converts the kinetic energy of wind into electrical energy. As a clean and renewable energy source, wind energy has been increasingly valued by countries around the world. Its reserves are huge. The global wind energy is about 2.74×10^9 MW, of which the exploitable wind energy is 2×10^7 MW, which is 10 times larger than the total exploitable water energy on the earth.
[0003] Currently, the propeller-type wind turbine is the most commonly used one in wind power generation. Common ones are two-blade and three-blade wind turbines, but there are also one-blade or more than four-blade wind turbines. The airfoil of this kind of wind turbine is similar to that of an airplane wing. In order to improve the starting performance and minimize the aerodynamic loss, components with high root strength and low tip strength and a helix angle are mostly used. However, this kind of wind power generator still has great deficiencies, such as high equipment cost, inconvenient installation and debugging, etc., and it can only output rated power when reaching at least the rated wind speed. In order to make the wind direction directly face the plane of the wind wheel rotation, direction control is required, which is not applicable to winds from all directions and has low power generation efficiency. Summary of the Invention
[0004] The present invention aims to solve at least the technical problems existing in the prior art, and particularly innovatively provides a novel wind power generation device and components, which can collect winds from multiple directions for power generation and have high power generation efficiency.
[0005] To achieve the above object of the present invention, the present invention provides a novel wind power generation device, including a power generation cylinder and an air guiding cylinder located below the power generation cylinder, and the power generation cylinder is communicated with the air guiding cylinder. The air guiding cylinder is conical with a smaller upper part and a larger lower part. A plurality of trumpet-shaped air inlet cylinders are provided on the outer side wall of the air guiding cylinder. A one-way valve that only allows wind to enter the air guiding cylinder is provided at the closed end of each air inlet cylinder. A spiral air duct is installed spirally on the inner side wall of the air guiding cylinder. Each air inlet cylinder is communicated with the spiral air duct, and the diameter of the spiral air duct gradually becomes smaller from bottom to top. The top of the spiral air duct forms a funnel-shaped air outlet with a smaller lower part and a larger upper part, and the wind is blown into the power generation cylinder through the air outlet;
[0006] The outer side wall of the power generation cylinder is provided with photovoltaic panels. A rain-proof cover is provided on the top of the power generation cylinder, and its outer side is also provided with photovoltaic panels. A lightning rod is provided on the top of the rain-proof cover; an air outlet is opened on the upper side wall of the power generation cylinder. A generator rotating shaft extending axially up and down is provided inside the power generation cylinder. Upper and lower power generation fan blades are fixedly connected to both ends of the generator rotating shaft. An upper fixing mechanism, a rotor permanent magnet and a lower fixing mechanism are sequentially arranged between the generator rotating shaft and the power generation cylinder from top to bottom;
[0007] The upper fixing mechanism comprises two disc fixing frames spaced apart from each other, the two disc fixing frames are grid-shaped, fixedly connected to the generator cylinder, and a clearance hole is provided in the middle for the generator rotating shaft to pass through, annular axial fixing magnets are provided on opposite sides of the two disc fixing frames, and the opposite sides of the two axial fixing magnets have only one magnetic pole and are opposite in polarity, a first fixing magnet ring is fixed on the outer sleeve of the generator rotating shaft, the first fixing magnet ring is located between the two axial fixing magnets, and the upper and lower sides of the first fixing magnet ring are respectively the same in polarity as the opposite side of the two axial fixing magnets, and a first buffer mechanism is provided between the first fixing magnet ring and the two axial fixing magnets;
[0008] A cylindrical fixing frame is arranged on the bottom side of the disc fixing frame located at the lower side, and the lower disc fixing frame and the cylindrical fixing frame are integrally fixedly connected to the generator cylinder; a cylindrical radial fixing magnet is fixed on the cylindrical fixing frame, and a cylindrical second fixing magnet ring is arranged at the center of the circular ring of the radial fixing magnet, and the second fixing magnet ring is fixedly sleeved on the rotating shaft of the generator, and the polarity of the side opposite to the second fixing magnet ring of the radial fixing magnet is the same and a radial buffer mechanism is arranged;
[0009] The rotor power generation magnet is located below the disc fixing frame on the lower side. The rotor power generation magnet is arc-shaped and is located outside the cylindrical fixing frame. A grid-shaped connecting disk is connected between the rotor power generation magnet and the generator rotating shaft. A power generation coil is provided on the inner wall of the power generation cylinder. The rotor power generation magnet is close to the stator power generation coil through the connecting disk, leaving an air gap in the middle. The power generation coil is connected to the power input end of the voltage regulator, and the power output end of the voltage regulator is connected to the battery or the power grid.
[0010] The lower fixing mechanism is located between the rotor power generation magnet and the lower power generation blade, and the lower fixing mechanism has the same composition as the upper fixing mechanism and is symmetrical with respect to the rotor power generation magnet.
[0011] The air inlet duct is used to let air in. The spiral air duct is used to direct the air towards the air outlet. The spiral setting of the spiral air duct not only satisfies the requirement of directing the air towards the upper air outlet but also can generate a rotating air current, facilitating the rotation of the power generation fan blades. The power generation fan blades are used to rotate driven by the wind force, thereby driving the rotor of the electromagnet to rotate through the generator rotating shaft, causing the stationary power generation coil to cut the magnetic field lines, generating induced current, and conducting power generation. The voltage stabilizer is used to stabilize the voltage, and the storage battery is used to store electrical energy. The disc fixing bracket is used to fix the axially fixed magnet, and the cylindrical fixing bracket is used to fix the radially fixed magnet. The two axially fixed magnets are used to prevent the first fixed magnet ring from moving up and down, thereby preventing the generator rotating shaft from moving up and down. The radially fixed magnet is used to prevent the second fixed magnet ring from moving left and right, thereby preventing the generator rotating shaft from moving left and right. The combined setting of the two axially fixed magnets and the first fixed magnet ring, as well as the combined setting of the radially fixed magnet and the second fixed magnet ring, are both based on the magnetic levitation principle, enabling the generator rotating shaft to be in a fully levitated state without any friction during rotation. The generator fan blades can start with a gentle breeze, the rotation speed is not limited, energy consumption is reduced, and wind power generation can be maximally utilized. The power generation is enhanced. Both the disc fixing bracket and the connecting disc are set in a grid shape, both of which are used to increase the air circulation speed, reduce the obstruction of air flow, and further enhance the power generation. The one-way valve is set to prevent air from being blown out from other air inlet ducts. Since the wind basically blows from one direction, at this time, the air inlet duct facing the wind direction is in an open state through the one-way valve to let air into the air guiding duct, and the air inlet duct facing away from the wind direction is in a closed state through the one-way valve. After the air enters the air guiding duct, it will not be blown out from other air inlet ducts under the action of the one-way valve and will only be blown out from the air outlet, ensuring the power generation efficiency. The photovoltaic panels set on the power generation cylinder and the rainproof cover conduct photovoltaic power generation, and the lightning rod is used to avoid lightning strikes and protect the equipment.
[0012] In the above solution: The first buffer mechanism includes a number of rolling elements arranged in a ring on the axially fixed magnets that are vertically opposite to the first fixed magnet ring. The rolling part of each rolling element faces the first fixed magnet ring, and the rolling direction of each rolling element is the same as the rotation direction of the first fixed magnet ring. The connecting column of the rolling element passes through the axially fixed magnet and is connected with a fixed anti-disengagement part on the other side of the axially fixed magnet;
[0013] A second buffer mechanism is also provided between the second fixed magnet ring and the radially fixed magnet. The second buffer mechanism has the same composition and principle as the first buffer mechanism, and the only difference is that the rolling elements of the second buffer mechanism are arranged along the circumferential direction of the second fixed magnet ring.
[0014] When the wind force is relatively large, it may cause the first and second fixed magnet rings to approach the axial and radial fixed magnets. The provided buffer mechanism can prevent the first and second fixed magnet rings from touching the axial and radial fixed magnets, and form rolling friction through the rolling elements, reducing the friction force and increasing the stability of the generator rotating shaft.
[0015] In the above solution: protective nets are provided at the closed ends of the air inlet ducts. A rotating door for closing the air inlet duct is rotatably connected to the inner side wall of the air inlet duct. A rotating shaft is provided on the side of the rotating door close to the air guiding duct. A tension spring is connected between the side of the rotating door far from the air guiding duct and the air inlet duct. The tension spring is detachably connected to the air inlet duct through a fixed hook. The rotating door is obtained by cutting the side wall of the lower half of the air inlet duct.
[0016] The protective net is used to prevent leaves, garbage or other foreign objects from entering the device and avoid causing blockage or other damages. In the case of strong wind, the rotatably arranged rotating door will be blown up by the strong wind and rest on the protective net to close the air inlet duct, thus preventing the internal equipment from being damaged by the strong wind. When the wind force returns to normal, the provided tension spring can facilitate the rotating door to return to its original position. The detachable connection of the tension spring to the air inlet duct enables, when inspection and maintenance are required, the end connected to the air inlet duct to be removed and hooked on the protective net to close the air inlet duct and prevent the wind from entering the air guiding duct, avoiding injury to the staff caused by the rotation of the power generation fan blades during maintenance and inspection.
[0017] In the above solution: all the air inlet ducts are arranged at intervals in sequence along the spiral direction of the spiral air duct. One of the air inlet ducts is directly communicated with the spiral air duct, and the remaining air inlet ducts are communicated with the spiral air duct through branch pipes.
[0018] In the above solution: several of the air inlet ducts are divided into several layers from top to bottom along the air guiding duct. The number of air inlet ducts in each layer is several, and the air inlet ducts are evenly arranged circumferentially along the air guiding duct. Preferably, there is one in each of the four directions of east, south, west, and north, a total of 4, or one in each of the eight directions of east, south, west, north, northeast, northwest, southeast, and southwest, a total of 8. The number of layers of the air inlet ducts depends on specific circumstances, such as factors like the geographical location where the power generation device is located, the local wind force, and the height of the air inlet duct.
[0019] In the above solution: guide wind grooves are spirally arranged on the inner side wall of the spiral air duct, and a power generation fan blade is also fixedly connected to the top end of the generator rotating shaft. This can make the wind form a swirling air flow in the spiral air duct, facilitating the rotation of the power generation fan blade.
[0020] In the above solution: the air guiding duct is made of a transparent material, and both the air guiding duct and the power generation duct are equipped with fixing frames made of light steel keel for fixed installation.
[0021] The transparent material allows sunlight to shine into the air intake duct, raising the temperature of the air inside the air intake duct and creating a high-temperature environment. In this high-temperature environment, the air flow will rise and flow along the air guide opening to the air outlet. It is made of transparent material and is usually relatively light. A fixing frame can be set to fix the device and prevent it from being blown away or lifted when the wind is strong. The fixing frame is made of the material of a light steel keel frame, which is convenient for workers to carry. When part of it is installed on the mountain, it can avoid the handling problems caused by the rugged mountain road and difficult walking.
[0022] In the above-mentioned new power generation device and new power generation component: the rotor permanent magnet, the axial fixed magnet, the radial fixed magnet, the first fixed magnet ring and the second fixed magnet ring are all made of permanent magnets, and the permanent magnets are preferably neodymium magnets. Without affecting the magnetic force, a number of hollow small holes are set on the permanent magnet, and the positions of the small holes are staggered from the positions of the rolling parts. Thereby reducing the weight of the whole device, especially reducing the load when the generator shaft rotates. The material of the buffer mechanism is preferably made of non-magnetic metal material;
[0023] Or the axial fixed magnet and the radial fixed magnet can also be made of electromagnets. A distance sensor is installed on the axial fixed magnet and the radial fixed magnet. When the first fixed magnet ring or the second fixed magnet ring approaches the axial fixed electromagnet or the radial fixed electromagnet, the distance sensor emits a signal to increase the magnetic force of the electromagnet and prevent the first fixed magnet ring or the second fixed magnet ring from approaching.
[0024] The present invention also provides a wind power generation method based on the above-mentioned new power generation device and power generation component, and the features are as follows:
[0025] 1). On one hand, the photovoltaic panels are laid on the outer side wall of the power generation cylinder and combined with the conical air intake duct made of the following transparent material to direct the wind to the power generation cylinder for power generation, and on the other hand, make full use of solar power generation. The concept is peculiar and the power generation efficiency is high;
[0026] 2). A number of horn-shaped air intake ducts are arranged from top to bottom outside the conical air intake duct, facing all directions of southeast, northwest, etc., which can collect wind energy from different directions and improve the use efficiency;
[0027] 3). A spiral rising air guide duct is installed from bottom to top inside the conical air intake duct, and the diameter of the air guide duct gradually becomes smaller to create a swirling air flow. The inner side wall of the spiral air duct is spirally provided with air guide grooves to increase the rotation force.
[0028] 4). An air flow one-way valve is set at the air intake duct to ensure that the wind only enters and does not exit.
[0029] 5). An automatic switch valve is set on the air intake duct. In special cases, the valve can be automatically closed, and in normal cases, it automatically resumes power generation. It is simple and applicable, saving labor costs.
[0030] 6), The generator shaft rotates and generates electricity in a suspended state through the magnetic levitation principle, making full use of wind energy and increasing power generation.
[0031] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:
[0032] 1. It can make the generator rotating shaft in a fully suspended state through the magnetic levitation principle, without any friction during rotation. The generator fan blades can start with gentle breeze, the rotation speed is not restricted, energy consumption is reduced, and wind energy is utilized to generate electricity to the greatest extent.
[0033] 2. The upper fixing mechanism, lower fixing mechanism and buffer mechanism are respectively located at the upper and lower ends of the generator rotating shaft, which can increase the stability of the generator rotating shaft during rotation.
[0034] 3. The setting of multiple layers of multiple air inlet tubes can increase the air intake volume and power generation; and the air inlet tubes are evenly arranged along the circumferential direction of the air guiding tube, which can collect wind from multiple directions, has a high application rate, and can convert the wind energy from multiple directions into electrical energy, with stronger practicability.
[0035] 4. The spirally arranged spiral air ducts and air guiding grooves can generate vortex air currents and increase power generation.
[0036] 5. The air inlet tube is transparent, and sunlight directly shines into the interior of the air inlet tube, increasing the temperature inside the tube, increasing the rising speed of the air inside the air inlet tube, and increasing the power generation wind force.
[0037] 6. Photovoltaic panels are laid on the outer sides of the power generation cylinder and the rain cover, which not only protects the power generation device inside the power generation cylinder but also makes full use of solar power generation, killing two birds with one stone.
[0038] 7. The rotating door provided on the air inlet tube can automatically close the air inlet tube in the case of particularly strong wind, protecting the power generation device from damage, and can automatically resume the power generation state under normal wind conditions. And it can also easily close the air inlet tube when the power generation device needs to be overhauled. This device is simple, has low investment, does not require manual monitoring, and saves costs.
[0039] 8. The new type of wind power generation device and power generation components can be large or small, are simple to install and disassemble, and are convenient to transport, fully saving installation, transportation and maintenance costs.
[0040] 9. The permanently magnet with a hollow setting can reduce the weight of the device, especially reduce the load of the generator shaft rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.
[0048] Embodiment 1
[0049] As Figure 1 and Figure 5 shown, a new type of wind power generation device includes a power generation cylinder 9 and an air guide cylinder 16 located below the power generation cylinder, and the power generation cylinder 9 is communicated with the air guide cylinder 16. The air guide cylinder 16 is conical with a smaller upper part and a larger lower part, and a plurality of air inlet cylinders 17 are provided on the outer side wall of the air guide cylinder 16. Preferably, the plurality of air inlet cylinders 17 are divided into several layers from top to bottom along the air guide cylinder 16, the number of air inlet cylinders in each layer is several, and the air inlet cylinders are evenly arranged along the circumferential direction of the air guide cylinder 16 and are respectively arranged in the four directions of east, south, west, and north ( Figure 1 In order to more clearly show the details of the spiral air duct, the air inlet cylinders on the front and back sides outside the air guide cylinder are omitted). To prevent the wind from blowing out from other air inlet cylinders 17, a one-way valve 23 that only allows the wind to enter the air guide cylinder 16 is provided at the closed end of each air inlet cylinder 17. A spiral air duct 18 is spirally installed on the inner side wall of the air guide cylinder 16 to enable the wind to spiral upward, generating a swirling air flow, which is convenient for driving the power generation fan blades 4 to rotate. Each air inlet cylinder 17 is communicated with the spiral air duct 18. To increase the blowing speed of the wind, the diameter of the spiral air duct 18 gradually decreases from bottom to top. To enhance the rotation effect of the wind, guide wind grooves 20 are spirally arranged on the inner side wall of the spiral air duct 18. The top of the spiral air duct 18 forms a funnel-shaped air outlet 15 with a smaller lower part and a larger upper part, and the wind is blown into the power generation cylinder 9 through the air outlet 15.
[0050] To prevent leaves and garbage from being blown into the device, protective nets 19 are provided at the closed ends of the air inlet ducts 17. A rotating door 22 for closing the air inlet duct 17 is rotatably connected to the inner side wall of the air inlet duct 17. Preferably, the rotating door 22 is obtained by cutting the side wall of the lower half of the air inlet duct 17, saving materials. A rotating shaft is provided on the side of the rotating door 22 close to the air guiding duct 16, and a tension spring 24 is connected between the side of the rotating door 22 far from the air guiding duct 16 and the air inlet duct 17. In the case of strong wind, the strong wind blows up the rotating door 22 and it is placed on the protective net 19 to close the air inlet duct 17, preventing the internal equipment from being damaged by strong wind. Preferably, the tension spring 24 is detachably connected to the air inlet duct 17 by a fixing hook. The detachable connection of the tension spring 24 to the air inlet duct 17 enables, when inspection and maintenance are required, the end connected to the air inlet duct 17 to be removed and hooked on the protective net 19 to close the air inlet duct and prevent wind from entering the air guiding duct, avoiding injury to the staff caused by the rotation of the generator fan blades during maintenance and inspection.
[0051] Preferably, the air guiding duct 16 is made of a transparent material. By allowing the inside of the air guiding duct 16 to absorb light, the temperature of the air inside the air guiding duct 16 can be increased to form a high-temperature environment, facilitating the upward flow of the air current towards the air outlet. Both the air guiding duct 16 and the power generation duct 9 are equipped with fixing frames made of light steel keel for fixed installation. Since the air guiding duct 16 is made of a transparent material and is usually of light weight, to prevent it from being blown down or blown up in strong wind, the fixing frame can fix the air guiding duct 16 and the power generation duct. The fixing frame is made of light steel keel, which is convenient for workers to carry, avoiding handling difficulties caused by rough mountain roads when some are installed on mountains and it is not easy to walk.
[0052] Photovoltaic panels 12 are laid on the outer side wall of the power generation duct 9. While generating electricity by absorbing sunlight through the photovoltaic panels 12, it can also prevent the sunlight from directly irradiating on the side wall of the power generation duct 9, to a certain extent preventing the temperature inside the power generation duct 9 from rising and avoiding the internal equipment of the power generation duct 9 from accelerating aging due to exposure to the sun. A rain cover 2 is provided at the top of the power generation duct 9. Preferably, photovoltaic panels 12 are also provided on the outer side of the rain cover 2. The provided photovoltaic panels 12 can generate solar power and make reasonable use of solar energy. A lightning rod 1 is provided at the top of the rain cover 2, which can prevent the device from being struck by lightning and protect the equipment. An air outlet 3 is opened on the upper side wall of the power generation duct 9, and a generator rotating shaft 8 with an axis extending vertically is provided inside the power generation duct 9. Upper and lower generator fan blades 4 are fixedly connected to both ends of the generator rotating shaft 8, and an upper fixing mechanism, a rotor permanent magnet 13, and a lower fixing mechanism are sequentially arranged between the generator rotating shaft 8 and the power generation duct 9 from top to bottom.
[0053] The upper fixing mechanism includes two grid-shaped disc fixing frames 5 arranged at intervals from top to bottom. Both disc fixing frames 5 are fixed on the inner side wall of the power generating cylinder 9, and a clearance hole is provided in the middle for the generator rotating shaft 8 to pass through. The two disc fixing frames 5 are provided with annular axial fixed magnets 6 on opposite sides, and there is only one magnetic pole on the opposite side of the two axial fixed magnets 6 and they are opposite to each other. The outer sleeve of the generator rotating shaft 8 is fixed with a first fixed magnet ring 7, which is located between the two axial fixed magnets 6, and the upper and lower sides of the first fixed magnet ring 7 are respectively the same as the polarity of the opposite side of the two axial fixed magnets 6, and the axial suspension of the generator rotating shaft is realized by using the principle that magnets of the same polarity repel each other. For example, if the magnetic property of the upper side of the first fixed magnet ring 7 is N pole, the magnetic property of the side of the axial fixed magnet 6 located above the first fixed magnet ring 7 and opposite to the magnetic ring 7 is also N pole; if the magnetic property of the lower side of the magnetic ring 7 is S pole, the magnetic property of the side of the axial fixed magnet 6 located below the first fixed magnet ring 7 and opposite to the magnetic ring 7 is also S pole.
[0054] A cylindrical fixing frame (33) is arranged at the bottom side of the disc fixing frame (5) located at the lower side, and the lower disc fixing frame (5) and the cylindrical fixing frame (33) are integrally fixedly connected to the generator cylinder (9); a cylindrical radial fixing magnet (10) is fixed on the cylindrical fixing frame (33), and a cylindrical second fixing magnet ring 11 is arranged at the center of the ring of the radial fixing magnet 10. The second fixing magnet ring 11 is fixed on the generator rotating shaft 8 with its outer sleeve, and the opposite sides of the radial fixing magnet 10 and the second fixing magnet ring 11 have the same polarity, and the radial suspension of the generator rotating shaft is realized by utilizing the principle that magnets of the same polarity repel each other.
[0055] A first buffer mechanism is provided between the first fixed magnet ring 7 and the two axial fixed magnets 6. The first buffer mechanism includes a plurality of universal balls 25 arranged in a ring shape on the upper and lower sides of the first fixed magnet ring 7. The rolling direction of each universal ball 25 is consistent with the rotation direction of the first fixed magnet ring 7. The connecting column 26 of the universal ball 25 passes through the axial fixed magnet 6 and is connected to a fixed anti-slip member 27 on the other side of the axial fixed magnet 6. When the generator shaft 8 deviates up and down due to the impact of wind or other factors such as instability, rolling friction can be formed between the universal ball 25 and the first fixed magnet ring 7. Compared with the sliding friction when the first fixed magnet ring 7 is in direct contact with the axial fixed magnet 6, the friction force is smaller, thereby ensuring the axial stability of the generator shaft.
[0056] A second buffer mechanism is also provided between the second fixed magnet ring 11 and the radial fixed magnet 10. The second buffer mechanism has the same composition and principle as the first buffer mechanism. The only difference is that the universal ball of the second buffer mechanism is arranged along the circumference of the second fixed magnet ring 11. It will not be described here. The second buffer mechanism ensures the radial stability of the generator shaft.
[0057] The rotor generating electromagnet 13 is located below the disc fixing bracket 5 on the lower side. The rotor generating electromagnet 13 is arc-shaped and is located outside the cylindrical fixing bracket 33. A generating coil 14 is provided on the inner side wall of the generating cylinder 9. Preferably, a grid-shaped connecting disc 30 is connected between the rotor generating electromagnet 13 and the generator rotating shaft 8, and the rotor generating electromagnet 13 is extended towards the generating coil 14 through the connecting disc 30, so that the rotor generating electromagnet 13 is close to the generating coil 14, making the magnetic field lines near the generating coil 14 denser and increasing the power generation amount. The generating coil 14 is connected to the power input end of the voltage stabilizer, and the power output end of the voltage stabilizer is connected to the charging end of the storage battery or the power grid. Preferably, the power supply end of the storage battery is connected to the voltage input end of the inverter.
[0058] The lower fixing mechanism is located between the rotor generating electromagnet 13 and the lower generating fan blade 4. The lower fixing mechanism has the same composition and principle as the upper fixing mechanism, and is vertically symmetric with respect to the rotor generating electromagnet 13, so it will not be elaborated here.
[0059] Preferably, the power supply output end of the photovoltaic panel 12 is connected to the power input end of the voltage stabilizer, and the electric energy converted by the photovoltaic panel is collected through the storage battery or the power grid to improve the power generation efficiency. Several irregular protrusions are provided on the surface of the generating fan blade 4, and the protrusions increase the friction between the generating fan blade 4 and the wind, facilitating the wind to push the generating fan blade 4 to rotate.
[0060] After the wind enters the spiral air duct 18 from the air inlet duct 17, since the spiral air duct 18 is spirally arranged in the air guiding duct 16, therefore, after the wind enters the spiral air duct 18, a swirling air flow will be generated, facilitating the rotation of the generating fan blade 4. The air guiding grooves 20 on the inner wall of the spiral air duct 18 will further increase the rotation speed. After the wind is blown into the generating cylinder 9 from the air outlet 15, it pushes the generating fan blade 4 to rotate, drives the rotor generating electromagnet 13 to rotate through the generator rotating shaft 8, so that the stationary generating coil 14 cuts the magnetic field lines to generate an induced current, and the voltage of the induced current is stabilized at a fixed value through the voltage stabilizer, and the electric energy is stored through the storage battery or transmitted to the external power system through the power grid.
[0061] The first fixed magnet ring 7 is clamped in the middle by two axial fixing magnets 6. According to the principle of repulsion between like magnets, the axial fixing magnet 7 is suspended in the middle of the two axial fixing magnets 6, avoiding the friction when the generator rotating shaft 8 rotates, and at the same time restricting the axial fixing magnet 7 to prevent displacement in the vertical direction, thereby avoiding displacement of the generator rotating shaft 8 in the vertical direction.
[0062] Similarly, by radially fixing the magnet 10, the second fixed magnet ring 11 is sleeved inside the circular ring. Also based on the principle of repulsion between like poles of magnets, the second fixed magnet ring 11 is suspended inside the circular ring of the radially fixed magnet 10, avoiding the frictional force during the rotation of the generator rotating shaft 8. At the same time, the second fixed magnet ring 11 is restricted to prevent displacement in the horizontal direction, thereby avoiding displacement of the generator rotating shaft 8 in the horizontal direction.
[0063] Embodiment 2
[0064] The difference between this embodiment and Embodiment 1 lies in:
[0065] As Figure 5 shown, the first buffer mechanism includes a number of first rollers 31 arranged in a ring on the axially fixed magnet 6. Opposite to the first fixed magnet ring 7, the rolling direction of each of the first rollers 31 on the upper and lower sides is the same as the rotation direction of the first fixed magnet ring 7, and the first rollers 31 are in a suspended state, with neither the top nor the bottom of the first rollers 31 contacting the axially fixed magnet 6. The connecting column 39 of the first roller 31 passes through the axially fixed magnet 6 and is connected with a fixed anti - detachment member 40.
[0066] The second buffer mechanism includes a number of second rollers 32 arranged in a ring on the radially fixed magnet 10. Opposite to the second fixed magnet ring 11, the rolling direction of the circumferentially arranged second rollers 32 is the same as the rotation direction of the second fixed magnet ring 11, and the second rollers 32 are in a suspended state, with the edges of the second rollers 32 not contacting the radially fixed magnet 10. The connecting column (38) of the second roller 32 passes through the radially fixed magnet 10 and is connected with a fixed anti - detachment member (37).
[0067] When the generator rotating shaft 8 moves up and down due to the impact of wind or other factors such as instability, rolling friction can be formed between the first rollers 31 and the first fixed magnet ring 7. Compared with the sliding friction when the first fixed magnet ring 7 directly contacts the axially fixed magnet 6, the frictional force is smaller, ensuring the axial stability of the generator rotating shaft; when the generator rotating shaft 8 moves left and right due to the impact of wind or other factors such as instability, rolling friction can be formed between the second rollers 32 and the second fixed magnet ring 11, ensuring the radial stability of the generator rotating shaft. When the generator rotating shaft rotates at a high speed, the stability can be increased due to the action of the buffer mechanism.
[0068] The present invention also provides a wind power generation method based on the above - mentioned new - type power generation device and power generation components, and its characteristics are as follows:
[0069] 1). On one hand, by combining the way that the outer side wall of the power generation cylinder (9) is paved with photovoltaic panels (12) and the conical air - guiding cylinder (16) made of the following transparent material, the wind is guided to the power generation cylinder for power generation, and on the other hand, solar energy is fully utilized for power generation. The concept is novel and the power generation efficiency is high;
[0070] 2), several horn-shaped air inlet ducts are arranged on the outside of the conical air guiding cylinder (16) from top to bottom, facing southeast, northwest, etc., which can collect wind energy from different directions and improve the usage efficiency.
[0071] 3), a spiral rising air guiding cylinder (18) is installed inside the conical air guiding cylinder (16) from bottom to top, and the diameter of the air guiding cylinder gradually becomes smaller to create a swirling air flow. The inner side wall of the spiral air guiding pipe (18) is spirally provided with air guiding grooves (20) to increase the rotation force.
[0072] 4), an air flow one-way valve (23) is arranged at the air inlet duct to ensure that the wind only enters and does not exit.
[0073] 5), an automatic switch valve (22) is arranged on the air inlet duct. In special cases, the valve can be automatically closed, and under normal circumstances, power generation is automatically restored. It is simple and applicable, saving labor costs.
[0074] 6), the generator rotating shaft (8) rotates and generates electricity in a suspended state through the principle of magnetic levitation, making full use of wind energy and increasing the power generation.
[0075] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. For example, the air inlet ducts can also be arranged in multiple directions (northeast, southeast, northwest, southwest), etc. The scope of the present invention is defined by the claims and their equivalents.
