Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a wind wheel wind power system with vertical ear-type wind blades. Background Art

[0002] The technology of harnessing wind power has been around for over a century. Nearly a hundred types of wind turbines, each with a variety of sizes and structures, have emerged around the world. The most famous and earliest of these, the Dutch three-blade turbine, is now widely used worldwide. Numerous smaller turbines with varying impeller structures have been invented, with China in particular accounting for over half of these inventions. For example, a micro-wind turbine generator system, mounted on the top of a roadside lighting pole, combines with a solar panel. The electricity generated is stored in batteries within the pole, which then illuminate the road at night. Due to its simple impeller design, the wind resistance is very low, and at low wind speeds, the impellers stop rotating. Therefore, a solar panel is required to compensate for this. Large-scale wind turbines are undoubtedly the Dutch three-blade turbines, with installed power exceeding 1,000 kW. They are widely used worldwide in coastal and shallow waters, as well as on land with wind speeds exceeding 3 meters per second year-round, making a significant contribution to the global clean energy supply.

[0003] However, global wind power technology has seen little progress in recent decades. Aside from small advances such as the Dutch three-blade turbine, which uses sensors to send signals to a control center when wind speeds rise due to weather changes such as typhoons, causing the blades to tilt to reduce headwind resistance and avoid the wind, and China's invention of micro-wind power generation devices for nighttime road lighting, replacing power grid electricity, progress has been largely stagnant.

[0004] The Dutch-style three-blade turbine, the dominant type of wind power generation worldwide, is very expensive to manufacture and even more expensive to install. Furthermore, transportation is extremely difficult when installed in mountainous areas. The installation site is extremely demanding, requiring altitudes of 100 meters or higher and consistent wind speeds of 3 meters per second or higher year-round. This is because wind speeds of at least 3 meters per second are required to propel the rotors. Consequently, these conditions are rare on land. For example, in China, these conditions are found in several harsh environmental areas in several northwestern provinces and in the eastern northern part of the Inner Mongolia Autonomous Region. However, these areas are uninhabited and lack roads, making the transmission network thousands of kilometers long to reach North China. Consequently, while investments are underway to install Dutch-style three-blade turbine systems in these areas, the resulting electricity is extremely expensive and unsustainable.

[0005] From micro wind turbines to large Dutch three-blade turbines, there are no wind power generation systems in the world that can be used inside buildings or installed on the roofs of buildings. There are also no medium-to-large wind power generation systems that can supply power to a factory, a farm, a village, a county town, etc.

[0006] To effectively utilize and improve wind energy efficiency, and capitalizing on the Earth's inexhaustible low-speed wind resources, we have developed a novel wind turbine system with vertical-ear blades through continuous calculations and experiments. Calculated at the same output power, the combined manufacturing and installation costs of this novel wind turbine system are less than one-sixth of those of a Dutch three-bladed turbine power generation system. As a result, humanity now has a safe power supply technology that requires significantly less investment and is more cost-effective than hydropower, is quick to install and disassemble, and allows for easy component replacement, all while ensuring virtually uninterrupted power. Summary of the Invention

[0007] In response to the problems in the related art, the present invention proposes a wind wheel wind power system with vertical ear-type wind blades to overcome the above-mentioned technical problems existing in the existing related art.

[0008] The vertical-ear blade wind turbine system of the present invention can operate in capacities ranging from a tiny 10 watts (W) to 100,000 kW or more. Due to its unique structure, it can operate even at wind speeds as low as 1.5 m / s or less. Therefore, taking China as an example, it can be used in over half of all regions, whether plains or mountainous, in the south or north, in cities or villages. If every county, town, or township were equipped with a vertical-ear blade wind turbine system, equipped with power generation and storage devices and a distributed power supply network, then even in the event of a major natural disaster or man-made disaster such as war, the national power transmission network would be protected from damage and power outages.

[0009] The technical principles of the present invention are as follows:

[0010] The core technology employed in this invention is an ear-shaped vertical impeller. The unique shape of the human and animal ears allows the receiver to trap faint sounds from a distance, which then resonate and amplify within the ear. The sound waves then reflect and vibrate the eardrum, transmitting them to the brain. Experiments have shown that, like an animal ear, the ear-shaped impeller of this invention traps wind when it enters the impeller. However, the continued flow of wind creates a superimposed wind pressure, driving the impeller to rotate. Even at very low wind speeds, the impeller can rotate at speeds of 1.5 m / s or less, thanks to the superimposed wind pressure.

[0011] To this end, the specific technical solutions adopted in the present invention are as follows:

[0012] A wind turbine system with vertical ear-type blades includes a plurality of vertically stacked wind turbine chambers, the sizes of which gradually decrease from bottom to top, an interval layer being provided between adjacent wind turbine chambers, and a vertical impeller matching the same being provided inside each wind turbine chamber; the vertical impeller includes a rotating shaft installed inside the wind turbine chamber, and both ends of the rotating shaft are connected to the wind turbine chamber via bearing discs, and a plurality of ear-type vertical blades are evenly provided on the outside of the rotating shaft.

[0013] Furthermore, to facilitate the installation of the vertical impeller, the wind wheel chamber includes a plurality of vertical columns arranged vertically, and the plurality of vertical columns form a regular polygonal structure. The tops and bottoms of adjacent vertical columns are connected by lower outer crossbeams, and the bottoms of adjacent vertical columns and the tops of the lower outer crossbeams are connected by upper outer crossbeams. The tops and bottoms of the vertical columns are each provided with a fixing plate, and the inner tops and bottoms of the vertical columns are provided with a mounting core ring, and the outer sides of the mounting core ring are connected to the vertical columns by horizontal support crossbeams. A windproof shutter mechanism is provided between adjacent vertical columns. The inner sides of the mounting core rings are each provided with a bearing adjustment plate that cooperates with the bearing disc.

[0014] Furthermore, in order to better cope with the attacks of typhoons and hurricanes, the wind-resistant rolling shutter mechanism includes a rolling shutter installed between the tops of adjacent vertical columns, and the side walls of the vertical columns are provided with guide rail grooves that cooperate with the rolling shutter, a number of wind-resistant support rods are arranged between the lower outer beam and the upper outer beam, and a number of rings that cooperate with the wind-resistant support rods are arranged on the inner side of the bottom of the rolling shutter.

[0015] Furthermore, in order to facilitate the connection of the rotating shafts in the upper and lower wind wheel chambers, diagonal support beams are provided inside the interval layer and between the horizontal support beams and the vertical columns, and grid support beams are provided between the diagonal support beams and the horizontal support beams and the vertical columns. The inner top and inner bottom of the interval layer are provided with clamping and releasing devices that cooperate with the rotating shaft.

[0016] Furthermore, to facilitate the connection between adjacent shafts, both ends of the shaft extend through the bearing disc and connect to universal joints located on the side of the bearing disc away from the shaft. Adjacent rotor chambers are also connected via universal joints. The shaft's diameter decreases at the end where it passes through the bearing disc, and a 10-50mm gap remains between the bearing disc and the junction between the large and small diameter ends of the shaft. Reinforced support rods are installed between the tops and bottoms of adjacent ear-shaped vertical blades, and circular retaining rings are installed between the outer tops and bottoms of the ear-shaped vertical blades.

[0017] Furthermore, in order to effectively improve the efficiency of wind energy utilization, the ear-shaped vertical fan includes a fan frame, one side of the fan frame is provided with a shaft connecting plate that matches the shaft, and the shaft connecting plate is provided with a plurality of shaft connecting holes; the other side of the fan frame is provided with pulleys at the top and bottom, and a pulley guide groove that matches the pulley is provided on the side of the horizontal support beam close to the pulley, and a plurality of fixing ring connecting holes that match the circular fixing ring are provided between the pulleys; the top and bottom of the fan frame are provided with support rod connecting holes that match the reinforcement support rod; the fan frame is provided with a matching skeleton inside, and the skeleton is composed of longitudinal bone plates and transverse bone plates, and the transverse bone plates are bent upward and backward and connected to the ear-shaped fan blade back plate located on one side of the transverse bone plates. The upper part of the ear-shaped fan blade back plate is deeply bent backward and upward and gradually bends shallowly at the lower part, and the ear-shaped fan blade back plate is made of rust-resistant metal sheet / cloth, or glass fiber composite material, or carbon fiber composite material, or plastic, or wood, or canvas made of weather-resistant material.

[0018] The beneficial effects of the present invention are: by utilizing the special shape and structure of human and animal ears to receive weak sounds from a distance, trap them, oscillate and amplify them back and forth in the ears, so that the sound waves are reflected, vibrate the eardrum and are transmitted to the brain nerves. The present invention designs the impeller into an ear-type vertical impeller imitation structure, so that the structure of the vertical impeller is similar to that of an animal ear. When wind blows into the ear-type impeller, it is trapped, and then a steady stream of wind blows into the impeller and forms a superimposed wind pressure to drive the impeller to rotate, so that the present invention can drive the impeller to rotate due to the superposition of wind even when the wind speed is very low. Compared with the traditional Dutch three-blade turbine system, the present invention not only effectively reduces the manufacturing and installation costs, but also can effectively improve the utilization efficiency of wind resources, thereby better realizing the utilization of low wind speed resources on the surface and better meeting the needs of wind power generation.

[0033] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0034] According to an embodiment of the present invention, a wind turbine wind power system with vertical ear-type wind blades is provided.

[0035] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-11 As shown, a wind turbine wind system with vertical ear-type blades according to an embodiment of the present invention includes a plurality of vertically stacked wind turbine chambers 1, wherein the sizes of the plurality of wind turbine chambers 1 gradually decrease from bottom to top, and a spacer layer 2 is provided between adjacent wind turbine chambers 1. In this way, the wind turbine chambers stacked together form a pyramid structure, thereby making the wind turbine wind system strong and reliable, capable of withstanding typhoons and hurricanes of any level. The rotating shafts in each wind turbine chamber are connected together through a universal joint, forming a wind output system with a large and novel vertical ear-type impeller, which outputs strong torque when rotating to drive an external generator set. In addition, in this embodiment, a single output system can also be composed of a single wind turbine chamber and a single vertical impeller.

[0036] Each rotor chamber 1 is equipped with a matching vertical impeller 3. The impellers can be manufactured with diameters ranging from a minimum of 20 cm to a maximum of 30 meters, and heights from a minimum of 10 cm to a maximum of 20 meters. Both miniature and large vertical impellers are installed within hexagonal or octagonal rotor chambers. The vertical impeller 3 includes a rotating shaft 4 mounted within the rotor chamber 1. Both ends of the rotating shaft 4 are connected to the rotor chamber 1 via bearing plates 5. Several ear-shaped vertical blades 6 are evenly distributed on the outside of the rotating shaft 4, and each ear-shaped vertical blade 6 is fixed to the rotating shaft 4 with screws.

[0037] In specific applications, vertical rotor chambers are stacked together to rotate against the wind, allowing large systems to be built up to 200 meters in height. The lower rotor chamber can be built with the largest diameter, the middle rotor chamber with a smaller diameter, and the upper rotor chamber with an even smaller diameter, forming a pyramid shape. This makes the entire system stable and resistant to typhoons, hurricanes, and earthquakes. Furthermore, during construction, hoisting components does not require an oversized professional crane; a horizontal crane or a lattice structure, like in building construction, can be used. When repairing or replacing components or parts, no specialized crane is required; components and parts can be assembled and disassembled directly using the individual vertical rotor chamber frames.

[0038] Furthermore, if a vertical-eared rotor wind turbine system is installed in a cold, snowy region, the entire system should be equipped with snowmelting and snow removal equipment to ensure normal operation during cold weather. The wind output system, constructed from stacked hexagonal or octagonal rotor chambers, is divided into three sections: upper, middle, and lower. Wind speed, temperature, and humidity sensors, as well as cameras, are installed on each side to monitor system performance. The entire system will be equipped with a 5G, or future 6G, intelligent control and automation center, automatically connecting to the local meteorological bureau's weather information center 24 hours a day. This will proactively analyze and automatically adjust one or more sides of the rotor chamber facing windward toward typhoons and hurricanes, lowering some or all wind-resistant roller shutters on the windward rotor chambers, or completely shutting down the entire vertical-eared rotor wind output system. The intelligent control and automation center can also be used to connect systems within a region or across multiple locations, enabling remote central monitoring.

[0039] In one embodiment, the wind wheel chamber 1 includes a plurality of vertical columns 7 arranged vertically, and a regular polygon structure is formed between the plurality of vertical columns 7. The top ends and bottom ends of adjacent vertical columns 7 are connected by a lower outer cross beam 8, and the bottom ends of adjacent vertical columns 7 and the tops of the lower outer cross beam 8 are connected by an upper outer cross beam 9; a fixing plate 10 is provided at the top and bottom ends of the vertical columns 7, a mounting core ring 11 is provided between the inner top and inner bottom of the vertical columns 7, a bearing adjustment plate 12 matching the bearing disk 5 is provided on the inner side of the mounting core ring 11, the outer side of the mounting core ring 11 and the vertical column 7 are connected by a horizontal support cross beam 13, and a wind-resistant rolling shutter mechanism is provided between adjacent vertical columns 7.

[0040] In practical applications, the rotor chamber consists of six or eight vertical columns, two layers of hexagonal or octagonal lower outer beams, and hexagonal or octagonal horizontal support beams. In small vertical impellers, the vertical columns, upper outer beams, and horizontal support beams can be made of wood, plastic, composite materials, or metal. In medium or large vertical impellers, the vertical columns, upper outer beams, and horizontal support beams are welded metal or cast concrete.

[0041] In one embodiment, the wind-resistant rolling shutter mechanism includes a rolling shutter 14 installed between the tops of adjacent vertical columns 7, and the side walls of the vertical columns 7 are each provided with a guide groove 15 that cooperates with the rolling shutter 14, a plurality of wind-resistant support rods 16 (made of stainless steel) are provided between the lower outer crossbeam 8 and the upper outer crossbeam 9, and a plurality of rings 17 that cooperate with the wind-resistant support rods 16 are provided on the inner side of the bottom of the rolling shutter 14;

[0042] In specific applications, when a typhoon or hurricane approaches, the windward-facing inlet shutter descends along the guide grooves mounted on the vertical columns. These wind-resistant support rods are captive to the shutter collars, providing wind resistance and allowing the shutter to be raised and lowered. The guide grooves mounted on the vertical columns on either side of the wind rotor chamber allow the shutter to be lowered and raised. All equipment that converts wind power into power is subject to typhoons and hurricanes. When the sensor detects strong winds, it commands the shutter to rotate downward along the guide grooves on the vertical columns, fully or partially closing the windward inlet. When the sensor detects that the strong wind has subsided and the wind speed has returned to normal, the shutter will rise upward, fully or partially into the compartment.

[0043] In one embodiment, because the bearing disks that hold the upper and lower rotating shafts of the vertical impellers are installed between the upper and lower horizontal six-legged or eight-legged horizontal support beams of the wind wheel chamber, a set of horizontal six-legged or eight-legged horizontal support beams is required. Each set of horizontal six-legged or eight-legged horizontal support beams is in a horizontal state, and a grid-type support assembly (including diagonal support beams and grid support beams) is required to ensure that the horizontal six-legged or eight-legged horizontal support beams remain in a solid and horizontal state. A set of hexagonal or octagonal mounting core rings is installed at the center core of each horizontal support beam. The mounting core rings are used to adjust the vertical accuracy and horizontal state of the rotating shafts of the upper and lower wind wheel chambers. A bearing adjustment assembly is installed on the mounting core ring to adjust the accuracy and tightness of the bearing disks that support the rotating shafts of the upper and lower vertical impellers.

[0044] Specifically, diagonal support beams 18 are provided inside the spacer layer 2 and between the horizontal support beams 13 and the vertical columns 7, and grid support beams 19 are provided between the diagonal support beams 18 and the horizontal support beams 13 and the vertical columns 7. The inner top and inner bottom of the spacer layer 2 are provided with clamping and releasing devices 20 that cooperate with the rotating shaft 4.

[0045] In this embodiment, the spacer layer not only conveniently and quickly connects the universal joints installed at both ends of the upper and lower rotor chamber shafts, but also connects the ends of the upper and lower shafts together for vertical joint rotation. The lower rotor chamber of the entire vertical ear-type wind turbine system is equipped with a clamping / releasing device on or below the bearing plate. When the wind speed in the lower section, i.e., near the ground, is too low to propel the vertical impeller, a wind speed sensor sends a signal to release the clamping / releasing device, disconnecting the lower vertical impeller from the entire vertical rotor chamber system. The rotational force of the vertical impellers in the middle and upper rotor chambers is then transmitted downward through the lower shaft to the ground or the power generation device below, driving the generator. When the wind speed sensor in the lower rotor chamber detects that the wind speed reaches a level sufficient to propel the vertical impeller, the clamping / releasing device clamps the shaft again, causing the vertical impeller in the lower rotor chamber to rotate in unison with the vertical impellers in the middle and upper rotor chambers.

[0046] In one embodiment, both ends of the rotating shaft 4 pass through the bearing plate 5 and are connected to a universal joint 21 located on the side of the bearing plate 5 away from the rotating shaft 4. Adjacent wind wheel chambers 1 are connected via the universal joint 21. The diameter of the rotating shaft 4 at one end through the bearing plate 5 becomes smaller, and a gap of approximately 10-50 mm is left between the connection between the large and small diameter ends of the rotating shaft 4 and the bearing plate 5, allowing for upward and downward movement. When wind blows toward the ear-shaped vertical fan blades, due to their special structure, the ear-shaped vertical fan blades will float and rotate, reducing the friction of the pulleys installed above and below the fan blade frame, and achieving the highest rotation efficiency of the ear-shaped vertical fan blades. Reinforced support rods 22 are provided between the tops and bottoms of adjacent ear-shaped vertical fan blades 6, and circular fixing rings 23 are provided between the outer tops and bottoms of the ear-shaped vertical fan blades 6.

[0047] In specific applications, the vertical impeller consists of five ear-shaped vertical blades and a rotating shaft. Large systems or systems where necessary can consist of 3-7 ear-shaped vertical blades and a rotating shaft. For vertical impellers with a diameter greater than 50 cm, a circular retaining ring is added at the top and bottom, screwed to the blade frame. For vertical impellers with a diameter greater than 3 meters, one or more circular retaining rings are added to the blade frame and tightened until the vertical impeller is secure. For vertical impellers with a diameter greater than 3 meters, the five ear-shaped vertical blades and the blade frame are tightened together using reinforced support rods and circular retaining rings, respectively, with screws until the vertical impeller is secure and does not deform.

[0048] In one embodiment, the ear-type vertical fan blade 6 is composed of a fan blade frame and a frame laid inside the fan blade frame, specifically including a fan blade frame 24. In a specific application, the fan blade frame 24 is made of corrosion-resistant metal, glass fiber composite material, or carbon fiber composite material. A shaft connecting plate 25 that cooperates with the rotating shaft 4 is provided on one side of the fan blade frame 24, and a plurality of shaft connecting holes 26 are opened on the shaft connecting plate 25.

[0049] In specific applications, when the diameter of the vertical impeller is greater than 3 meters, pulleys 27 are provided on the top and bottom of the other side of the fan blade frame 24, and a pulley guide groove 28 is provided on the side of the horizontal support beam 13 close to the pulley 27 to match it. For vertical impellers with larger diameters, one or more pulleys are installed on the upper and lower parts of the fan blade frame, corresponding to the pulley guide grooves at the corresponding positions above and below the horizontal support beam, so that the vertical impeller can rotate smoothly. In addition, the bearing adjustment plate in the middle of the upper and lower horizontal six-foot or eight-foot horizontal support beams of the wind wheel chamber is installed with a bearing disk that covers the upper and lower rotating shafts of the vertical impeller, and is combined with the impeller rotating shaft, with a gap of 10-50mm reserved above and below, and a gap of 10-50mm is also reserved above and below between the pulley positions installed on the upper and lower parts of the fan blade frame corresponding to the lower horizontal six-foot or eight-foot horizontal support beams of the wind wheel chamber and the pulley guide groove. When the vertical impeller rotates, the special ear-type structure of its ear-type vertical fan blade will make the vertical impeller float when rotating. Due to the absence or minimal friction, the vertical impeller rotates faster and generates greater torque under superimposed wind pressure. Compared to a Dutch three-blade turbine with the same cross-sectional area, the torque is more than five times greater. Several retaining ring connection holes 29 are provided between the pulleys 27 to accommodate the circular retaining rings 23. The top and bottom of the blade frame 24 are provided with support rod connection holes 30 to accommodate the reinforced support rods 22. A matching skeleton 31 is provided within the blade frame 24. In practical applications, the skeleton 31 forms a grid-like structure. Specifically, the skeleton 31 is composed of longitudinal and transverse plates, each of which is curved upward and backward and connected to an ear-shaped blade backplate 32 located on one side of the transverse plate. The ear-shaped blade backplate 32 is shaped like an animal's ear, with a deep upward and backward curve at the top and a gradually shallower curve at the bottom. The ear-shaped blade backplate 32 is made of corrosion-resistant metal sheet / cloth, fiberglass composite, carbon fiber composite, plastic, wood, or weather-resistant canvas.

[0050] To sum up, with the help of the above technical scheme of the present invention, by utilizing the special shape structure of human and animal ears to receive weak sounds from a distance, trap them, oscillate and amplify them back and forth in the ears, so that the sound waves are reflected, vibrate the eardrum and are transmitted to the brain nerves, the present invention designs the impeller into an ear-type vertical impeller imitation structure, so that the structure of the vertical impeller is similar to that of an animal ear, when wind blows into the ear-type impeller, it is trapped, and then a steady stream of wind blows into the impeller and forms a superimposed wind pressure to drive the impeller to rotate, so that the present invention can drive the impeller to rotate due to the effect of wind superposition even when the wind speed is very low. Compared with the traditional Dutch three-blade turbine system, the present invention not only effectively reduces the manufacturing and installation costs, but also can effectively improve the utilization efficiency of wind resources, thereby better realizing the utilization of low wind speed resources on the surface and better meeting the needs of wind power generation.

[0051] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
