Description

Technical Field

[0001] The invention relates to the technical field of wind turbines, and more particularly to a golden spiral-shaped vortex-shaped self-wind-seeking horizontal-axis vortex wind turbine with a bullet-shaped deflector. Background Art

[0002] Wind turbines can be divided into lift type and drag type according to the force they are subjected to; according to the direction of the axis, they can be divided into horizontal axis and vertical axis. For any wind turbine, high power coefficient and high torque are advantages, but high solidity is a disadvantage, and area ratio and mass are the key factors affecting solidity.

[0003] The three-blade wind turbine is a model of lift-type generator. Its working principle is that when air flows through the blades, it generates a force perpendicular to the direction of the airflow speed, that is, lift. Therefore, the system requires that the airflow must hit the blades at a precise angle to obtain the best lift, thereby driving the blades to rotate, driving the generator to operate, and finally generating electricity. Because the wind blows in the horizontal direction in most cases, the system requires that the blades must have an angle of attack in order to obtain the maximum wind energy and generate the strongest lift. In order to make the angle of attack of each part of the blade roughly the same, some parts must meet the wind at different angles, which leads to the angle of attack of some parts of the blade meeting the requirements, while the angle of attack of some parts deviates. The slenderness of the blades determines the high tip speed, which can usually reach several times or even dozens of times the wind speed. Therefore, the energy obtained under high wind speed is higher, which is also a significant feature of the three-blade wind turbine. For the three-blade wind turbine, the solidity is the ratio of the blade area to the blade swept circle area, and the mass is also a key parameter affecting the solidity. Under the same specifications, the solidity of three-blade wind turbines is lower than that of four-blade wind turbines; and for two wind turbines with the same power, the wind turbine with heavier blades has greater solidity. Therefore, in the solidity comparison, three-blade wind turbines are better than four-blade wind turbines, and lighter wind turbines are better than heavier wind turbines, but the overall solidity is not superior. Combining the advantages of the system, it is more suitable for installation in areas with excellent wind energy, and it is also the one with the most installed and widely used wind turbines. However, it is still impossible to ignore the disadvantages of three-blade wind turbines, such as high wind speed requirements, harsh environment, large size, heavy weight, high difficulty in transportation and hoisting, high tower pressure, and unfriendly ecological environment.

[0004] The resistance-type vertical axis wind turbine relies on the direct pressure of wind on the blades to generate power. When the pressure on the blades moving with the wind is greater than the resistance encountered in the headwind movement, the impeller is driven to rotate and output power. The advantage is that wind energy can be captured under any circumstances. The disadvantage is that one blade captures wind energy, and the other blade perpendicular to it moves against the wind, thus generating headwind resistance. The net torque that drives the wind turbine to rotate is equal to the torque of the blade that captures wind energy minus the resistance torque of the blade that moves against the wind. There are obvious shortcomings, resulting in a low wind energy utilization coefficient, so it is difficult to promote and not installed much. Although the existing vertical axis wind turbines have the characteristics of diversified structures and can be started under light wind conditions, their wind energy utilization coefficient is still low. The root cause lies in the mechanical structure limitations of vertical axis wind turbines, which lead to an imbalance in the investment and return ratio, directly hindering the expansion and upgrading of such wind turbines in the field of wind power generation.

[0005] In view of the many shortcomings of horizontal axis three-blade wind turbine and vertical axis wind turbine, this golden spiral vortex horizontal axis vortex wind turbine is specially designed. This wind turbine is expanded and improved with the characteristics and advantages of Archimedean spiral lifting turbine with large torque. The design introduces the three-dimensional vortex impeller and vortex wind track formed by the classic golden spiral dividing line. At the same time, the deflector design is added to accurately guide the airflow to interact with the three-dimensional vortex wind track in a smooth and smooth manner, effectively reducing the generation of airflow turbulence, so that the fan can be started in a low wind speed environment. In order to make the swept area and the windward area overlap in the largest proportion to reduce the solidity coefficient, the spiral blade is supported by a horizontal axis to rotate around the axis. The self-seeking wind support frame is installed on the top of the rotating platform, so that the entire impeller always keeps the maximum resistance surface facing the wind, so as to achieve the maximum torque difference under the action of the wind, so as to keep the wind direction and the windward surface at the best angle at all times, improve the utilization rate of wind energy and also achieve the effect of self-seeking wind. In order to improve the system, the invention has carried out corresponding adjustments and optimizations in the corresponding mechanical structure layout, overall shape shaping and material selection, so that the wind energy utilization coefficient (Cp) has been significantly improved. The invented golden spiral vortex wind turbine has the remarkable characteristics of breeze start, high efficiency, light weight, easy transportation, simple installation, flexible mobility, strong scene adaptability, etc. In the era of affordable access to the grid, the invention provides a better choice for the field of breeze power generation.

[0007] The present invention provides the following technical solution: a golden spiral vortex-shaped self-winding horizontal axis vortex wind turbine generator set with a bullet-shaped deflector, including a self-winding support frame, the interior of the self-winding support frame is provided with two bearing seat connectors, which are respectively placed at the generator end and the electromagnetic brake end, and one end of the two bearing seat connectors is respectively provided with bearing seat mounting holes for fixedly connecting the bearing seat, the internal bearing of the bearing seat is fixedly sleeved with the impeller rotating shaft, and the outside of the impeller rotating shaft is fixedly connected to the spiral vortex impeller. The spiral vortex impeller is a structure generated by a moving point leaving a fixed base point at a constant speed and a constant angular velocity. The spiral vortex impeller is formed by opening corresponding through holes on the spiral fins outside the impeller rotating shaft, and then the spiral blades are firmly connected to the impeller rotating shaft by bolts or rivets. The bearing seat connector at the generator end is externally fixedly connected to a bolt mounting plate of a bullet-shaped air deflector. The structural design of the bullet-shaped air deflector effectively reduces the wind resistance coefficient. A soft rubber cover groove is provided on the outside of the bullet-shaped air deflector. The soft rubber cover groove is movably connected to a square soft rubber cover. The square soft rubber cover can optimize the airflow and reduce the friction and turbulence noise between the airflow and the blades and other components. It can make the wind flow smoother, reduce the noise level, and reduce noise pollution to the surrounding environment. The internal fixed connection bolt mounting plate of the bullet-shaped air deflector is used to facilitate the use of bolts to fix the bullet-shaped air deflector to the outside of the bearing seat connector.

[0008] Furthermore, a generator is provided inside the bullet-shaped fairing, and the shaft end of the generator is fixedly connected to a coupling. The selected coupling can not only reduce the vibration and noise caused by shaft misalignment, thereby improving the stability of the system; at the same time, when selecting the coupling, the type of coupling should be determined based on the local annual wind speed; the outside of the generator is fixedly connected to a generator fixing rod, and the generator fixing rod is fixedly connected to a bearing seat connector. The generator and the bearing seat connector can be fixed by the generator fixing rod, thereby stabilizing the generator.

[0009] Furthermore, bolt grooves are provided on the tops of the two bearing seat connectors, and the internal movably sleeved lifting bolt rings of the bolt grooves can be installed when the equipment is lifted; and when lifting is not required, the lifting bolt rings can be removed from the inside of the bolt grooves, thereby not affecting the windward area of ​​the impeller.

[0010] Furthermore, the two bearing seat connectors are respectively fixedly connected to the bearing seats, and the internal bearing part of the bearing seat is fixedly sleeved on the impeller rotating shaft. The two bearing seats provide a stable installation position for the impeller rotating shaft, which can withstand various loads transmitted by the bearings and the shaft system, and the bearing seats are designed with lubricating oil channels and grease storage space inside, which can provide good lubrication conditions for the bearings. The bearing seats can also prevent leakage of lubricating oil or grease to maintain the stability of the lubrication system.

[0011] Furthermore, an electromagnetic brake mounting hole is provided at one end of the bearing seat connector at the electromagnetic brake end for fixedly connecting the stator part of the electromagnetic brake. The rotor part of the electromagnetic brake is fixedly sleeved on the impeller rotating shaft. The electromagnetic brake ensures that the system will not stall when the external wind speed is high, and at the same time ensures that the generator will not be overloaded. A single friction plate electromagnetic brake is selected here. The electromagnetic brake consists of two parts: a stator part and a rotor part. The stator part is fixed to the self-seeking wind support frame, and the rotor part is fixed on the shaft.

[0012] Furthermore, the bottom of the self-wind-seeking support frame is fixedly connected to the first connecting plate, and the internal fixed welded reinforcing ribs of the self-wind-seeking support frame strengthen the stability of the self-wind-seeking support frame. The bottom of the self-wind-seeking support frame is fixedly connected to the first connecting plate, and a bolt hole is opened at the bottom of the first connecting plate for installing the bottom slewing bearing.

[0013] Furthermore, the inner ring of the first connecting plate is fixedly connected to the slewing bearing, and the outer ring of the slewing bearing is fixedly connected to the second connecting plate. The first connecting plate and the second connecting plate are fixed to the upper and lower surfaces of the slewing bearing by inserting bolts into the first connecting plate and the second connecting plate. The slewing bearing is then equipped with rolling bodies, so that the slewing bearing can be driven to turn while the wind drives the impeller to rotate. The bottom of the second connecting plate is fixedly connected to the support base, and the hexagonal connecting part at the bottom will be adjusted accordingly according to the actual connection condition with the wind turbine tower. In addition, the base part has reserved cable positions and fixed installation positions for conductive rings.

[0014] Technical effects and advantages of the present invention: 1. High and stable wind energy utilization coefficient Cp: The turbine-shaped blades formed by the golden spiral dividing line of the present invention penetrate the impeller through the horizontal axis, and the support frame designed in combination with its three-dimensional wind bucket-shaped structure realizes the maximum overlap of the wind sweeping area and the working area, so that the wind energy utilization coefficient of the turbine fan is much higher than that of fans of the same level; the bullet-shaped deflector accurately guides the airflow through the vortex-shaped wind track, and can interact in a stable and smooth manner, effectively reducing the generation of airflow turbulence, so that the fan can start and run smoothly in a low wind speed environment, filling the wind energy capture blind spot of conventional fans, and further improving the wind energy utilization coefficient; at the same time, it also shows a better power generation effect under high wind speed conditions, supporting the maintenance of the wind energy utilization coefficient at a high level; the self-seeking wind support frame is installed on the top of the rotating platform, so that the entire impeller always keeps the maximum resistance surface facing the wind, and the torque difference generated under the action of the wind causes the wind direction and the windward surface of the impeller to always maintain the best angle. The special design of self-seeking wind further improves the wind energy utilization coefficient, and ultimately promotes the comprehensive power generation efficiency of the system to a higher level. According to current theoretical research and practical measurement results, the wind energy utilization coefficient Cp is in the range of 40% to 44%, which is a higher value but also has a smaller fluctuation range.

[0015] 2. Strong adaptability to the power grid: In addition to relying on the current grid-connected technical support, this turbine fan also relies on its unique spiral vortex impeller structure design and auxiliary guide cover to accurately guide the airflow through the vortex wind track. It can interact in a smooth manner, effectively reducing the generation of airflow turbulence, so that the fan can maintain effective and stable operation in a wider wind speed range. From breeze to strong wind, it can smoothly convert wind energy into electrical energy. The output power has a large flexible adjustment range, and the output power curve changes smoothly, which meets the grid's requirements for input power stability.

[0016] 3. Automatic wind-seeking without yaw drive or tail wing: The self-seeking wind support frame is installed on the top of the rotating platform, so that the entire impeller always keeps the maximum resistance surface facing the wind. The torque difference generated by the wind causes the wind direction and the windward surface of the impeller to always maintain the best angle. The special design of self-seeking wind further improves the wind energy utilization coefficient Cp.

[0017] 4. Light weight, easy to transport and easy to install: The unique design of the present invention makes the fan system light weight, easy to transport and easy to install, solving the shortcomings and difficulties of many fans.

[0018] 5. Flexible and adaptable to different scenarios: This wind turbine is suitable for installation in a wide range of geological conditions. The model can be large or small, and it has the advantages of maintaining the wind energy utilization coefficient unchanged. It is flexible and adaptable to different scenarios.

[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The golden spiral self-seeking horizontal-axis wind turbine with a bullet-shaped fairing involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0032] The present invention provides a golden spiral-shaped vortex-shaped self-winding horizontal axis vortex wind turbine with a bullet-shaped deflector, comprising a self-winding support frame 1, wherein two bearing seat sleeve connectors 2 are provided inside the self-winding support frame 1, and are respectively disposed at the generator end and the electromagnetic brake end, and one end of each of the two bearing seat sleeve connectors 2 is provided with a bearing seat mounting hole for fixedly connecting a bearing seat 112, wherein the internal bearing of the bearing seat 112 is fixedly sleeved with an impeller rotating shaft 3, and the outside of the impeller rotating shaft 3 is fixedly connected with a spiral-shaped vortex-shaped impeller 4, and the spiral-shaped vortex-shaped impeller 4 is a structure generated by a moving point leaving a fixed point at a constant speed and a constant angular velocity, and the spiral-shaped vortex-shaped impeller 4 is a spiral-shaped impeller outside the impeller rotating shaft 3. Corresponding through holes are opened on the fins, and the spiral blades are firmly connected to the impeller rotating shaft 3 by bolts or rivets, so that a spiral vortex impeller 4 is formed by three mutually intertwined spiral blades, which mainly obtains power through the resistance component of the axial thrust generated by the wind. The bearing seat connector 2 at the generator end is externally fixedly connected to the bullet-shaped air deflector 5, and the bullet-shaped air deflector 5 is placed in a stable external wind field. A stable wind speed is given along the windward direction of the tip of the bullet-shaped air deflector 5, and the speed is set to 10m / s. From the fluid mechanics analysis results of the bullet-shaped air deflector 5, it can be seen that due to the streamlined design of the tip of the air deflector, the wind speed around the cylindrical part of the air deflector is improved to about 10.5m / s. The design structure of the bullet-shaped air deflector 5 obtained through optimization effectively reduces the wind resistance coefficient, so that the wind resources are more fully utilized. The outside of the bullet-shaped air deflector 5 is provided with a soft rubber cover groove 6, and the square soft rubber cover 7 is movably sleeved inside the soft rubber cover groove 6. The square soft rubber cover 7 can reduce the friction and turbulent noise between the airflow and the blades and other components by optimizing the airflow flow. It can make the wind flow more stable, reduce the noise level generated when the wind turbine is running, and reduce the noise pollution to the surrounding environment. The bullet-shaped air deflector 5 is provided with a bolt mounting plate 8, which is used to facilitate the use of bolts to fix the bullet-shaped air deflector 5 to the outside of the generator end bearing seat socket 2.

[0033] In a preferred embodiment, a generator 101 is provided inside the bullet-shaped fairing 5, and the shaft end of the generator 101 is fixedly connected to a coupling 102. The selected coupling 102 not only has the function of transmitting torque, but also has the ability to compensate for axial, radial and angular deviations. Such a design can reduce the vibration and noise caused by shaft misalignment, thereby improving the stability of the system. At the same time, when selecting the coupling 102, the type of coupling should be determined based on the local annual wind speed, because the local annual wind speed determines the rotation speed of the impeller, and thus determines the rotation speed of the transmission shaft. The stator housing of the generator 101 is fixedly connected to the generator fixing rod 103, and the generator fixing rod 103 uses the external thread to connect and fix the generator 101 to the bearing seat socket 2, thereby fixing the generator 101.

When the equipment is hoisted, the two lifting bolt rings 105 can be installed; when hoisting is not required, the lifting bolt rings 105 can be removed from the inside of the bolt grooves 104, so as not to affect the windward area of ​​the impeller.

[0035] In a preferred embodiment, the two bearing seat connectors 2 (located at the generator end and the electromagnetic brake end, respectively) are fixedly connected to the bearing seat 112 on the outside. The two bearing seats 112 provide a stable installation position for the impeller rotating shaft 3, which can withstand various loads transmitted by the bearing and the shaft system, including radial loads, axial loads, etc. It ensures that the bearing maintains the correct position and relative relationship during operation, prevents the shaft from shifting and shaking, and the bearing seat 112 is designed with a lubricating oil channel and a grease storage space inside, which can provide good lubrication conditions for the bearing and reduce the wear and friction of the bearing. At the same time, the bearing seat 112 also prevents the leakage of lubricating oil or grease and maintains the stability of the lubrication system. In this long-rotating fan equipment, good lubrication is crucial to extend the life of the bearing and improve the reliability of the equipment.

[0036] In a preferred embodiment, the outside of one of the bearing seat sleeves 2 is fixedly connected to the electromagnetic brake 106, and the rotor part of the electromagnetic brake 106 is fixedly sleeved on the impeller rotating shaft 3. The electromagnetic brake 106 ensures that the system will not stall when the external wind speed is high, and at the same time ensures that the generator will not be overloaded. This single friction plate electromagnetic brake is selected, which uses the principle of electromagnets to control the separation and braking of the power transmission through a 24V DC power supply, and brakes when powered on and separates when powered off. It is used in a dry environment and does not require oil immersion. The electromagnetic brake 106 consists of two parts: a stator part and a rotor part. The stator part is fixed to the bearing seat sleeve 2, and the rotor part is fixed to the impeller rotating shaft 3.

[0037] In a preferred embodiment, the bottom of the self-wind-seeking support frame 1 is fixedly connected to the first connecting plate 107, and the internal fixed welded reinforcing ribs 111 of the self-wind-seeking support frame 1 strengthen the stability of the self-wind-seeking support frame 1. The bottom of the self-wind-seeking support frame 1 is fixedly connected to the first connecting plate 107, and the first connecting plate 107 is provided with bolt holes for fixing the inner ring of the slewing bearing 108.

[0038] In a preferred embodiment, the bottom of the first connecting plate 107 is fixedly connected to the inner ring of the slewing bearing 108, and the outer ring of the slewing bearing 108 is fixedly connected to the second connecting plate 109. The inner ring of the slewing bearing 108 is fixed to the bottom of the first connecting plate 107 by bolts sleeved on the first connecting plate 107, and the second connecting plate 109 is also fixed to the bottom of the outer ring of the slewing bearing 108 by bolts. The slewing bearing 108 is equipped with rolling bodies, which can drive the slewing bearing 108 to turn while the wind drives the impeller to rotate. The bottom of the second connecting plate 109 is fixedly connected to the support base 110, and the hexagonal connecting part at the bottom will be adjusted accordingly according to the actual connection status with the wind turbine tower. In addition, the base part has reserved cable positions and fixed installation positions for conductive rings.

[0039] The working principle of the present invention is as follows: two bearing seat connectors 2 are provided inside the self-seeking wind support frame 1, which are respectively placed at the generator end and the electromagnetic brake end. One end of each of the two bearing seat connectors 2 is provided with a bearing seat mounting hole for fixedly connecting the bearing seat 112. The internal bearing of the bearing seat 112 is fixedly connected to the impeller rotating shaft 3. The outside of the impeller rotating shaft 3 is fixedly connected to the spiral vortex impeller 4. The spiral vortex impeller 4 is a structure generated by a moving point leaving a fixed point at a constant speed and a constant angular velocity. The spiral vortex impeller 4 is formed by opening corresponding through holes on the fins outside the impeller rotating shaft 3, and then the spiral blades are firmly connected to the impeller rotating shaft 3 by bolts, thereby being formed by three mutually intertwined spiral blades. The swept wind area and the work area of ​​the spiral vortex impeller 4 are completely overlapped, and the resistance component decomposed by the axial thrust generated by the wind is used to generate power. The external part of the bearing seat connector 2 at the generator end is fixedly connected to the bullet-shaped air deflector 5. The bullet-shaped air deflector 5 is placed in a stable external wind field, and a stable wind speed is given along the windward direction of the tip of the bullet-shaped air deflector, with a speed of 10m / s. From the results of the fluid mechanics analysis of the bullet-shaped air deflector 5, it can be seen that due to the streamlined design of the tip of the air deflector, the wind speed around the cylindrical part of the air deflector is improved, reaching about 10.5m / s. The structure of the bullet-shaped air deflector 5 with an optimized design effectively reduces the wind resistance coefficient, so that wind resources are more fully utilized. The square soft rubber cover 7 can reduce the friction and turbulent noise between the airflow and the blades and other components by optimizing the airflow flow. It can make the flow of wind more stable, reduce the noise level generated during the operation of the wind turbine, and reduce the noise pollution to the surrounding environment. The bullet-shaped air deflector 5 is provided with a bolt mounting plate 8, which is used to facilitate the use of bolts to fix the bullet-shaped air deflector 5 to the outside of the bearing seat connector 2 at the generator end. The inside of the bullet-shaped fairing 5 is provided with a generator 101, and the shaft end of the generator 101 is fixedly connected with a coupling 102. The selected coupling 102 not only has the function of transmitting torque, but also has the ability to compensate for axial, radial and angular deviations. Such a design can reduce the vibration and noise caused by shaft misalignment, thereby improving the stability of the system. At the same time, when selecting the coupling 102, it should be determined whether to use a high-speed coupling or a low-speed coupling based on the local perennial wind speed, because the local perennial wind speed determines the rotation speed of the impeller, and thus determines the rotation speed of the transmission shaft. The stator housing of the generator 101 is fixedly connected to the generator fixing rod 103, and the outside of the generator fixing rod 103 is fixedly connected to the bearing seat socket 2. One end of the bearing seat socket 2 at the generator end is provided with a generator fixing rod 103 mounting hole, and the generator 101 can be fixedly connected to the outside of the bearing seat socket 2 through the generator fixing rod 103, thereby stabilizing the generator 101.The tops of the two bearing seat connectors 2 are provided with bolt grooves 104, and the inside of the bolt grooves 104 is movably sleeved with lifting bolt rings 105, one of which is installed on the top of the motor-end bearing seat connector 2, and the other is installed on the top of the electromagnetic brake-end bearing seat connector 2. When the equipment is hoisted, the two lifting bolt rings 105 can be installed; when there is no need to hoist, the lifting bolt rings 105 can be removed from the inside of the bolt grooves 104, so as not to affect the windward area of ​​the impeller. One end of the two bearing seat connectors 2 is provided with a bearing seat mounting hole for fixedly sleeved bearing seat 112. The internal bearing of the bearing seat 112 is fixedly sleeved with the impeller rotating shaft 3. The bearing seat 112 provides a stable installation position for the impeller rotating shaft 3, and can withstand various loads transmitted by the bearing and the shaft system, including radial loads, axial loads, etc. It ensures that the bearing maintains the correct position and relative relationship during operation, prevents the shaft from shifting and shaking, and the bearing seat 112 is designed with a lubricating oil channel and grease storage space inside, which can provide good lubrication conditions for the bearing and reduce the wear and friction of the bearing. At the same time, the bearing seat 112 also prevents the leakage of lubricating oil or grease and maintains the stability of the lubrication system. In this high-speed rotating fan equipment, good lubrication is crucial to extend the life of the bearing and improve the reliability of the equipment. Another bearing seat connector 2 is fixedly connected to the electromagnetic brake 106, and the rotor part of the electromagnetic brake 106 is fixedly connected to the impeller rotating shaft 3. The electromagnetic brake 106 ensures that the system will not stall when the external wind speed is high, and at the same time ensures that the generator will not be overloaded. This single friction plate electromagnetic brake is selected, which uses the principle of electromagnets to control the separation and braking of the power transmission through a 24V DC power supply, power-on braking, and power-off separation. It is used in a dry environment and does not require oil immersion. The electromagnetic brake 106 consists of two parts: a stator part and a rotor part. The stator part is fixed to the bearing seat connector 2, and the rotor part is fixed to the impeller rotating shaft 3.The bottom of the self-seeking wind support frame 1 is fixedly connected to the first connecting plate 107. The internal fixed welded reinforcing ribs 111 of the self-seeking wind support frame 1 strengthen the stability of the self-seeking wind support frame 1. The bottom of the self-seeking wind support frame 1 is fixedly connected to the first connecting plate 107. The first connecting plate 107 is provided with bolt holes for fixing the inner ring of the slewing bearing 108.

The slewing bearing 108 is fixedly connected to the second connecting plate 109 by the bolts sleeved on the first connecting plate 107. 08 The inner ring is fixed to the bottom of the first connecting plate 107, and the second connecting plate 109 is also fixed to the bottom of the outer ring of the slewing bearing 108 by bolts. The slewing bearing 108 is equipped with rolling bodies, which can drive the slewing bearing 108 to turn while the wind drives the impeller to rotate. The bottom of the second connecting plate 109 is fixedly connected to the support base 110, and the hexagonal connecting part at the bottom will be adjusted accordingly according to the actual connection status with the wind turbine tower. In addition, the base part has reserved cable positions and fixed installation positions for conductive rings.

[0040] The present invention is derived from the expansion and improvement of the Archimedean screw-lift turbine, and integrates the characteristics of the screw-lift turbine such as large torque. The specially designed golden spiral dividing line guides the three-dimensional vortex impeller and vortex wind track, and uses a horizontal axis to support the vortex impeller so that the impeller rotates around the horizontal axis, thereby ensuring the overlap of the swept area and the windward area to the greatest extent; the designed self-wind-seeking support frame is installed on the top of the rotating platform, so that the entire impeller always keeps the maximum resistance surface facing the wind, and the torque difference generated under the action of the wind causes the wind direction and the impeller windward surface to always maintain the best angle, and the special design of the self-wind-seeking further improves the wind energy utilization coefficient; its bullet-shaped deflector accurately guides the airflow through the vortex wind track, and interacts in a smooth and stable manner, effectively reducing the generation of airflow turbulence, so that the fan can be started in a low wind speed environment, and further improving the wind energy utilization coefficient. The present invention accurately integrates the characteristics of both horizontal-axis and vertical-axis fans into the same architecture system, so that the fan has the remarkable characteristics of breeze start-up, high efficiency, light weight, easy transportation, simple installation, maneuverability, and strong scene adaptability.
