Description

Technical Field

[0001] This invention relates to the field of wind turbine technology, specifically to a wind turbine's flow guiding device. Background Technology

[0002] Wind power generation refers to a method of generating electricity by using wind power to drive blades to rotate and convert the kinetic energy generated by the blades into electrical energy. It is favored for its clean, pollution-free, and renewable characteristics. The wind turbine rotates under the action of wind power, converting the kinetic energy of the wind into mechanical energy. The wind turbine shaft accelerates the low-speed rotation to the high speed required by the generator through a gearbox or direct drive system. The generator uses the principle of electromagnetic induction to convert mechanical energy into electrical energy. Existing wind turbines are mainly divided into vertical axis wind turbines and horizontal axis wind turbines. Among them, the vertical axis wind turbine refers to a wind turbine with the rotating shaft perpendicular to the ground and the blades are evenly arranged around the rotating shaft. Therefore, the vertical axis wind turbine can receive wind from multiple directions, does not require a yaw device, and its structure has a strong ability to adapt to the environment. Most existing vertical axis wind turbine blades use an inclined surface to guide the wind direction and improve the wind energy absorption efficiency. However, the inclined surface of the blade also increases the wind flow speed, which reduces the time that the wind stays on the blade surface and leads to wind instability. Therefore, we propose a wind turbine guiding device. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a flow guiding device for a wind turbine, including an annular base, a generator assembly fixedly connected to the inner side of the annular base, a rotating shaft rotatably connected to the top of the generator assembly via a rotating bolt, a flow guiding mechanism fixedly connected to the outer side of the rotating shaft, and an elastic protective mechanism fixedly connected to the outer side of the rotating shaft. The flow guiding mechanism includes a fixed ring, a fixed round rod is fixedly connected to the inner side of the fixed ring, and an inclined flow guide plate is fixedly connected to one side of the fixed ring. An inlet square groove is opened on one side of the inclined flow guide plate. By setting an inlet square groove on one side of the inclined flow guide plate, the wind that comes into contact with the inclined flow guide plate can enter and stay for a period of time, preventing the inclined flow guide plate from flowing and dispersing rapidly to the surroundings along the inclined surface of the inclined flow guide plate when it comes into contact with the wind, which would cause unstable wind force. The elastic protection mechanism is provided in three parts, and the three elastic protection mechanisms are distributed on the outside of the rotating shaft. The end of the fixed round rod away from the fixed ring is fixedly connected to the outside of the rotating shaft. Multiple fixed round rods are provided, and the multiple fixed round rods are distributed inside the fixed ring. There are two fixed rings, and the two fixed rings are respectively distributed at the top and bottom of the inclined guide plate. Multiple inclined guide plates are provided, and the multiple inclined guide plates are distributed between two fixed rings. Multiple inlet square grooves are provided, and the multiple inlet square grooves are distributed on one side of the inclined guide plates. A cleaning component is fixedly connected to the top of the inclined guide plate, and a spiral baffle is fixedly connected to the inner wall of the inlet trough. The spiral baffle interferes with and intercepts the incoming airflow, preventing the airflow from flowing too quickly to a position where it is no longer in contact with the inclined guide plate, despite the slope. The spiral baffle, with its inner hollowed-out side, allows fine dust particles entering with the airflow to be discharged along with the airflow direction, preventing dust accumulation when the interception area within the inlet trough is large. Dust particles and impurities can cause the inlet channel to become clogged and unusable in a short time. A triangular baffle is fixedly connected to the side of the inclined guide plate near the inlet channel. The triangular baffle is set on the side of the inclined guide plate near the inlet channel to intercept blocky debris in the wind. This prevents large blocky debris in the wind from hitting the spiral baffle repeatedly when the wind is strong, which would gradually damage the spiral baffle and make it unusable. Multiple triangular baffles are provided and are distributed on the side of the inclined guide plate, which is aligned with the inlet channel.

[0004] Furthermore, the cleaning assembly includes a top fixing plate, a return spring fixedly connected to one side of the top fixing plate, and a square sliding plate fixedly connected to the end of the return spring away from the top fixing plate. A limiting rod is fixedly connected through and to one side of the square sliding plate. By setting the limiting rod on one side of the top fixing plate to pass through the square sliding plate and internally support and limit the return spring, it prevents the extended return spring from being easily twisted and deformed by the wind when the wind is strong, causing the square sliding plate to deviate from its sliding path and become unusable. A limiting block is fixedly connected to the end of the limiting rod away from the top fixing plate. By setting the limiting block at the end of the limiting rod away from the top fixing plate, it blocks and limits the square sliding plate, preventing the square sliding plate from slipping out of the limiting rod's through-limiting position as the return spring extends and slides, causing it to deviate and become difficult to return to its original position. A bottom rounded corner rod is fixedly connected to the bottom of the square sliding plate. By setting the bottom of the square slide bar with rounded corners that are smooth surfaces, the airflow can be facilitated to glide over it. This prevents the airflow from being blocked near the inlet square channel, which would prevent the airflow from making full contact with the surface of the inclined guide plate. Hard arc brushes are fixedly connected to both sides of the bottom rounded corner bar. When the hard arc brushes move with the bottom rounded corner bar, they clean the inside of the inlet square channel and the spiral baffle. This prevents the debris that gradually accumulates in the inlet square channel and the spiral baffle after long-term use from accumulating and blocking the airflow. The bottom of the top fixed plate is fixedly connected to the top of the inclined guide plate, and the bottom of the square slide bar is slidably connected to the top of the inclined guide plate. The end of the limiting rod away from the limiting circle is fixedly connected to one side of the top fixed plate. Multiple hard arc brushes are provided, and the multiple hard arc brushes are distributed on both sides of the bottom rounded corner bar.

[0005] Furthermore, the elastic protection mechanism includes an arc-shaped air cushion. By placing a compressible, elastic arc-shaped air cushion on the outside of the rotating shaft, it provides elastic protection against lumpy debris in the wind, preventing the rotating shaft from being gradually damaged by repeated impacts from lumpy debris over prolonged use. An arc-shaped protective sliding plate is fixedly connected to the outside of the arc-shaped air cushion. This allows lumpy debris to slide quickly to the surrounding area and provides a covering protection to the surface of the arc-shaped air cushion, preventing some of the sharp lumpy debris flying with the wind from gradually puncturing the arc-shaped air cushion and causing damage that renders it unusable. A return spring is fixedly connected to the inner wall of the arc-shaped air cushion. By placing a return spring between the arc-shaped inner support plate and the inner wall of the arc-shaped air cushion, the arc-shaped air cushion expands and returns to its initial state, preventing it from gradually deforming after repeated impacts, causing the compressible space to gradually decrease and rendering it ineffective. To provide elastic cushioning, the end of the return spring away from the arc-shaped air cushion is fixedly connected to an arc-shaped inner support plate. By setting the arc-shaped inner support plate inside the arc-shaped air cushion, the inner wall of the arc-shaped air cushion near the arc-shaped protective slide is covered and internally supported. This prevents flying debris from impacting the surface of the arc-shaped air cushion where the return spring is not located, thus ensuring that the rotation shaft is still affected by a certain impact force. A circular sleeve is fixedly connected to the side of the arc-shaped inner support plate near the return spring. A T-shaped round rod is fixedly connected through and to the side of the circular sleeve away from the arc-shaped inner support plate. The arc-shaped air cushion is provided with an arc-shaped rubber pad with an internal arc-shaped cavity. The side of the arc-shaped air cushion away from the arc-shaped protective slide is fixedly connected to the outer side of the rotation shaft. Multiple return springs are provided, and the multiple return springs are distributed on the inner wall of the arc-shaped air cushion. The end of the T-shaped round rod away from the circular sleeve is fixedly connected to the inner wall of the arc-shaped air cushion.

[0006] This invention provides a flow guiding device for a wind turbine. It has the following beneficial effects: 1. The wind turbine's airflow guiding device features an inlet groove on one side of the inclined guide plate, allowing airflow that contacts the plate to enter and remain for a period of time. This prevents the wind from rapidly dispersing outwards along the inclined surface of the guide plate when in contact with the wind, thus preventing unstable wind force. A rigid arc brush moves along with the bottom rounded corner rod to clean the inside of the inlet groove and the spiral baffle, preventing debris from accumulating in the inlet groove and spiral baffle over time and causing blockages that affect airflow. A compressible elastic arc-shaped air cushion is installed on the outside of the rotating shaft to provide elastic protection against blocky debris in the wind, preventing damage to the rotating shaft caused by continuous impact from blocky debris over time.

[0007] 2. The wind turbine's airflow guiding device includes a flow guiding mechanism. A triangular baffle is positioned near the inlet groove on one side of the inclined guide plate to intercept large, chunky debris in the wind. This prevents excessively large debris from repeatedly impacting the spiral rotor blades during strong winds, which could gradually damage them and render them unusable. The inlet groove on one side of the inclined guide plate allows wind to enter and remain for a period of time, preventing the wind from rapidly dissipating outwards along the inclined surface of the guide plate upon contact with the wind. The instability of the wind caused by the movement of air is addressed by installing spiral baffles inside the inlet channel to interfere with and intercept the incoming air. This prevents the airflow from flowing quickly away from the inclined guide plate due to the slope. The spiral baffles with hollowed-out inner sides allow fine dust particles that enter with the wind to be discharged along with the wind direction. This prevents the accumulation of dust particles and impurities in the inlet channel when the interception area is large, which would cause the channel to become clogged and unusable in a short time.

[0008] 3. The wind turbine's airflow guiding device is equipped with a cleaning component. A limiting rod is installed on one side of the top fixed plate to pass through the square slide plate and internally support and limit the return spring. This prevents the return spring from easily twisting and deforming due to wind force when the wind is strong, which would cause the square slide plate to deviate from its sliding path and become unusable. A limiting block is installed at the end of the limiting rod away from the top fixed plate to block and limit the square slide plate. This prevents the square slide plate from slipping out of the limiting rod and becoming difficult to reset when it slides continuously as the return spring extends. A hard arc brush moves with the bottom rounded corner rod to clean the inside of the inlet square groove and the spiral baffle. This prevents the debris that gradually accumulates in the inlet square groove and spiral baffle after long-term use from being difficult to discharge and causing blockages that affect the airflow. The slide rod at the bottom of the square slide plate is designed with rounded corners with smooth surfaces at all four corners to facilitate the airflow. This prevents the airflow from being blocked near the inlet square groove, which would prevent the airflow from making full contact with the surface of the inclined guide plate.

[0009] 4. The wind turbine's deflector is equipped with an elastic protection mechanism. A compressible, elastic, arc-shaped air cushion is placed on the outside of the rotating shaft to provide elastic protection against airborne debris. This prevents the rotating shaft from being gradually damaged by the continuous impact of debris over prolonged use. Arc-shaped protective sliding plates are placed on the outside of the air cushion to facilitate the rapid sliding of debris and to cover the surface of the air cushion, preventing sharp debris from puncturing the air cushion and causing damage. Effective use involves installing an arc-shaped inner support plate on the inner side of the arc-shaped air cushion to provide a covering support to the side of the arc-shaped air cushion near the arc-shaped protective sliding plate. This prevents flying debris from impacting the surface of the arc-shaped air cushion at locations without a return spring, thus ensuring that the rotation axis is still affected by a certain impact force. The return spring between the arc-shaped inner support plate and the inner wall of the arc-shaped air cushion facilitates the expansion and restoration of the arc-shaped air cushion to its initial state. This prevents the arc-shaped air cushion from gradually deforming after repeated impacts, which would cause the compressible space to gradually decrease and make it unable to effectively play its elastic buffering role.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Please see Figures 1-6 The present invention provides a flow guiding device for a wind turbine, including an annular base 1, a generator assembly 2 fixedly connected to the inner side of the annular base 1, a rotating shaft 3 rotatably connected to the top of the generator assembly 2 via a rotating bolt, a flow guiding mechanism 4 fixedly connected to the outer side of the rotating shaft 3, and an elastic protective mechanism 5 fixedly connected to the outer side of the rotating shaft 3. The flow guiding mechanism 4 includes a fixed ring 401, a fixed round rod 402 is fixedly connected to the inner side of the fixed ring 401, an inclined flow guiding plate 403 is fixedly connected to one side of the fixed ring 401, and an inlet square groove 404 is opened on one side of the inclined flow guiding plate 403. Three elastic protection mechanisms 5 are provided, and the three elastic protection mechanisms 5 are distributed on the outside of the rotating shaft 3. The end of the fixed round rod 402 away from the fixed ring 401 is fixedly connected to the outside of the rotating shaft 3. Multiple fixed round rods 402 are provided, and the multiple fixed round rods 402 are distributed inside the fixed ring 401. There are two fixed rings 401, and the two fixed rings 401 are respectively distributed at the top and bottom of the inclined guide plate 403. Multiple inclined guide plates 403 are provided, and the multiple inclined guide plates 403 are distributed between two fixed rings 401. Multiple inlet square grooves 404 are provided, and the multiple inlet square grooves 404 are distributed on one side of the inclined guide plates 403. A cleaning component 405 is fixedly connected to the top of the inclined guide plate 403, a spiral baffle 406 is fixedly connected to the inner wall of the inlet square channel 404, and a triangular baffle 407 is fixedly connected to the side of the inclined guide plate 403 near the inlet square channel 404. Multiple triangular baffles 407 are provided, and the multiple triangular baffles 407 are distributed on one side of the inclined guide plate 403 at a position that is aligned with the inlet square channel 404. The cleaning component 405 includes a top fixing plate 4051. A retraction spring 4052 is fixedly connected to one side of the top fixing plate 4051. A square sliding plate 4053 is fixedly connected to the end of the retraction spring 4052 away from the top fixing plate 4051. A limiting rod 4054 is fixedly connected through and to one side of the square sliding plate 4053. A limiting round block 4055 is fixedly connected to the end of the limiting rod 4054 away from the top fixing plate 4051. A bottom rounded corner rod 4056 is fixedly connected to the bottom of the square sliding plate 4053. Hard arc brushes 4057 are fixedly connected to both sides of the bottom rounded corner rod 4056. The bottom of the top fixing plate 4051 is fixedly connected to the top of the inclined guide plate 403. The bottom of the square sliding plate 4053 is fixedly connected to the top of the inclined guide plate 403. The top sliding connection of 03, the end of the limiting rod 4054 away from the limiting round block 4055 is fixedly connected to one side of the top fixed plate 4051, and multiple hard arc brushes 4057 are provided, and multiple hard arc brushes 4057 are distributed on both sides of the bottom rounded corner rod 4056. When in use, the wind comes into contact with the guide device and pushes the guide device to drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the outer elastic protection mechanism 5 to rotate together. When the rotating shaft 3 rotates, the mechanical energy is converted into electrical energy through the generator assembly 2. At the same time, a large area of ​​elastic protection mechanism 5 is set on the outside of the rotating shaft 3 to provide elastic collision protection for the rotating shaft 3. When the wind comes into contact with the inclined guide plate 403, it flows along the inclined surface of the inclined guide plate 403. The sloping airflow, after being separated by the triangular baffle 407 upon contact with it, enters the inlet trough 404. The triangular baffle 407, positioned near the inlet trough 404 on one side of the sloping guide plate 403, intercepts any blocky debris carried in the air. The inlet trough 404, located on one side of the sloping guide plate 403, allows the air in contact with it to remain for a period of time. After remaining within the spiral baffle 406 for a period, the air flows towards the fixed ring 401 and is discharged. The spiral baffle 406 within the inlet trough 404 further interferes with and intercepts the incoming airflow. The spiral baffle 406, with its inner hollowed-out side, allows the air to enter along with the airflow. Fine dust particles can be discharged into the inlet trough 404 along with the wind direction. At this time, the inclined guide plate 403 is pushed by the wind force to drive the fixed ring 401 to rotate. When the fixed ring 401 rotates, it drives the rotating shaft 3 to rotate through the fixed round rod 402 to generate wind power. When the inclined guide plate 403 is pushed by the wind force to rotate, it drives the top cleaning component 405 to rotate together. When the inclined guide plate 403 rotates with the fixed ring 401, it drives the top fixed plate 4051, the return spring 4052, the square sliding plate 4053, the limiting rod 4054 and the limiting round block 4055 to rotate together. When the return spring 4052 rotates with the inclined guide plate 403, it gradually extends away from the top fixed plate 4051 due to centrifugal force.When the return spring 4052 extends, the square slide plate 4053, with one end sleeved on the limiting rod 4054, also slides away from the top fixed plate 4051. The limiting rod 4054, located on one side of the top fixed plate 4051, passes through the square slide plate 4053 and internally supports and limits the return spring 4052. A limiting block 4055, located at the end of the limiting rod 4054 away from the top fixed plate 4051, blocks and limits the square slide plate 4053. As the square slide plate 4053 moves, it drives the bottom rounded corner rod 4056 and the hard arc brush 4057 to move together. The hard arc brush 4057, moving with the bottom rounded corner rod 4056, cleans the inside of the inlet square groove 404 and the spiral baffle 406. The rounded corners of the bottom slide rod of the square slide plate 4053 facilitate airflow.

[0014] Please see Figures 1-8This invention provides a wind turbine's airflow guiding device: an elastic protective mechanism 5 includes an arc-shaped air cushion 501, an arc-shaped protective sliding plate 502 fixedly connected to the outer side of the arc-shaped air cushion 501, a return spring 503 fixedly connected to the inner wall of the arc-shaped air cushion 501, an arc-shaped inner support plate 504 fixedly connected to the end of the return spring 503 away from the arc-shaped air cushion 501, a circular sleeve 505 fixedly connected to the side of the arc-shaped inner support plate 504 near the return spring 503, a T-shaped round rod 506 penetrating and fixedly connected to the side of the circular sleeve 505 away from the arc-shaped inner support plate 504, and the arc-shaped air cushion 501 having an internal... An arc-shaped rubber pad with an arc-shaped cavity is used. The side of the arc-shaped air cushion 501 away from the arc-shaped protective slide plate 502 is fixedly connected to the outer side of the rotating shaft 3. Multiple return springs 503 are provided and distributed on the inner wall of the arc-shaped air cushion 501. The end of the T-shaped round rod 506 away from the circular sleeve 505 is fixedly connected to the inner wall of the arc-shaped air cushion 501. In use, as the inclined guide plate 403 guides the airflow, it will eventually flow to the inner side of the fixed ring 401 near the rotating shaft 3, contact the arc-shaped protective slide plate 502, and then disperse along the sliding surface of the arc-shaped protective slide plate 502. When the airflow is accompanied by... When lumpy debris is encountered, it comes into contact with and impacts the arc-shaped protective sliding plate 502 as the wind flows, causing the arc-shaped air cushion 501 to be compressed. This compresses the inner arc-shaped support plate 504, pushing it inward and compressing the return spring 503. Simultaneously, the inner arc-shaped support plate 504 pushes the circular sleeve 505 inward, causing it to slide relative to the T-shaped rod 506. By setting a compressible elastic material arc-shaped air cushion 501 on the outside of the rotating shaft 3, lumpy debris in the wind is elastically blocked. The arc-shaped protective sliding plate 502 on the outside of the arc-shaped air cushion 501 facilitates the movement of lumpy debris. The object slides quickly outwards and provides a protective cover to the surface of the arc-shaped air cushion 501. An arc-shaped inner support plate 504 is installed on the inner side of the arc-shaped air cushion 501 to provide a protective cover to the side of the inner wall of the arc-shaped air cushion 501 near the arc-shaped protective slide plate 502. After the blocky debris slides off the surface of the arc-shaped protective slide plate 502, the return spring 503 loses its impact force and pushes the arc-shaped inner support plate 504 through its extension force to cause the arc-shaped air cushion 501 to expand and return to its initial state. The return spring 503 is installed between the arc-shaped inner support plate 504 and the inner wall of the arc-shaped air cushion 501 to facilitate the expansion and return of the arc-shaped air cushion 501 to its initial state.

[0015] In operation, the wind comes into contact with the guide device and drives it to rotate the rotating shaft 3. The rotation of the rotating shaft 3 causes the outer elastic protection mechanism 5 to rotate as well. When the rotating shaft 3 rotates, the mechanical energy is converted into electrical energy through the generator assembly 2. At the same time, the large-area elastic protection mechanism 5 is set on the outside of the rotating shaft 3 to provide elastic collision protection for the rotating shaft 3. When the wind comes into contact with the inclined guide plate 403, it flows along the inclined surface of the inclined guide plate 403. The wind flowing along the inclined surface of the inclined guide plate 403 comes into contact with the triangular baffle 407 and is divided by the triangular baffle 407 before entering the inlet square groove 404. The triangular baffle 407 is set on one side of the inclined guide plate 403 near the inlet square groove 404 to protect the wind from impact. The system intercepts lumpy debris carried by the wind. An inlet groove 404 is provided on one side of the inclined guide plate 403 to allow wind that comes into contact with the guide plate 403 to enter and remain for a period of time. The wind entering the inlet groove 404 remains within the spiral baffle 406 for a period before flowing towards the fixed ring 401 and being discharged. The spiral baffle 406 within the inlet groove 404 interferes with and intercepts the incoming wind. The spiral baffle 406, with its inner hollowed-out side, allows fine dust particles that enter with the wind to be discharged along with the wind direction. At this time, the inclined guide plate 403 is pushed by the wind force, causing the fixed ring 401 to rotate. As the fixed ring 401 rotates, it... The fixed-circle rod 402 drives the rotating shaft 3 to rotate for wind power generation. The inclined guide plate 403, propelled by the wind, rotates, causing the top cleaning assembly 405 to rotate as well. As the inclined guide plate 403 rotates with the fixed ring 401, it also drives the top fixed plate 4051, the return spring 4052, the square sliding plate 4053, the limiting rod 4054, and the limiting block 4055 to rotate together. As the return spring 4052 rotates with the inclined guide plate 403, it gradually extends away from the top fixed plate 4051 due to centrifugal force. When the return spring 4052 extends, the square sliding plate 4053, with one end sleeved on the limiting rod 4054, also extends away from the top fixed plate 4051. The sliding mechanism utilizes a limiting rod 4054 on one side of the top fixed plate 4051 to pass through the square slide plate 4053 and internally support and limit the return spring 4052. A limiting block 4055 is provided at the end of the limiting rod 4054 away from the top fixed plate 4051 to block and limit the square slide plate 4053. When the square slide plate 4053 moves, it drives the bottom rounded corner rod 4056 and the hard arc brush 4057 to move together. When the hard arc brush 4057 moves with the bottom rounded corner rod 4056, it cleans the inside of the inlet square groove 404 and the inside of the spiral baffle 406. The sliding rod at the bottom of the square slide plate 4053 is designed with rounded corners that are smooth surfaces to facilitate the flow of air.As the inclined guide plate 403 guides the airflow, it eventually flows to the inner side of the fixed ring 401 near the rotating shaft 3, where it contacts the arc-shaped protective sliding plate 502 and then disperses along the sliding surface of the arc-shaped protective sliding plate 502. When the airflow is accompanied by blocky debris, it will contact and impact the arc-shaped protective sliding plate 502 with the airflow, causing the arc-shaped air cushion 501 to be compressed, pushing the inner arc-shaped support plate 504 to move inward and compressing the return spring 503. At the same time, the inner arc-shaped support plate 504 will push the circular sleeve 505 to move inward together and slide relative to the T-shaped round rod 506. By setting a compressible elastic material arc-shaped air cushion 501 on the outside of the rotating shaft 3, blocky debris in the airflow is effectively contained. The system employs an elastic protective barrier. An arc-shaped protective sliding plate 502 is installed on the outer side of the arc-shaped air cushion 501 to facilitate the rapid sliding of debris to all sides, providing a protective cover over the surface of the air cushion 501. An arc-shaped inner support plate 504 is installed on the inner side of the air cushion 501 to provide a protective cover over the side of the inner wall of the air cushion 501 closest to the arc-shaped protective sliding plate 502. After the debris slides off the surface of the arc-shaped protective sliding plate 502, the return spring 503 loses its impact force and, through its extension force, pushes the arc-shaped inner support plate 504, causing the arc-shaped air cushion 501 to expand and return to its initial state. The return spring 503, located between the arc-shaped inner support plate 504 and the inner wall of the arc-shaped air cushion 501, facilitates the expansion and return of the air cushion 501 to its initial state.
