Abstract
Description
Technical Field
[0001] This invention relates to the field of micro wind generator technology, specifically a micro wind generator with intelligent monitoring function. Background Technology
[0002] Micro-wind generators are an important way to generate electricity and store energy by utilizing ground breezes. Energy storage can ensure a stable power supply and is widely used in various situations, such as outdoor travel and disaster relief.
[0003] Micro wind turbines typically employ intelligent control systems to automatically adjust the blade angle and rotation speed based on changes in wind speed and direction, thereby ensuring power generation efficiency. However, micro wind turbines are primarily used for wind power generation near the ground, which is considered low-altitude power generation. They are affected by ground forces, resulting in complex airflow fields and unstable wind conditions, which can easily impact power generation stability.
[0004] In addition, due to severe weather conditions during disaster relief, power generation stability is greatly affected. Conventional micro wind turbines have limited functions and cannot perform intelligent monitoring to ensure power generation stability. Summary of the Invention
[0005] The purpose of this invention is to provide a micro wind generator with intelligent monitoring function to solve the problems raised in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] The micro wind generator includes a casing, a transducer, a wind collector, and a base. The base has a mounting groove, the casing is placed in the mounting groove, the transducer is connected to the casing, and the wind collector is connected to the transducer. The wind collector is used to adjust the windward area.
[0008] The base serves as the main support foundation, installed on the ground, and the casing is mounted through mounting slots. The casing is used to install the energy conversion device. The wind collection device automatically collects the breeze and transmits it to the energy conversion device, converting its mechanical energy into electrical energy and storing it. It is conventionally used for wind power generation. However, due to the low-altitude power generation, the airflow field is complex and the wind force is not constant due to the influence of ground forces. During disaster relief, the windward area can be adjusted according to different wind conditions to improve the conversion stability. At the same time, the wind force is intelligently detected, and when the wind force is too strong, the mode is switched to avoid damage.
[0009] Furthermore, the transducer includes a stator, a rotor, and an input shaft. The housing is provided with a transducer cavity, and the stator and rotor are respectively placed in the transducer cavity. The input shaft is rotatably connected to the transducer cavity, one end of the input shaft passes through the transducer cavity, the rotor is fastened to the input shaft, and one end of the input shaft is drivenly connected to the air collecting device.
[0010] The air collection device includes a central shaft, an input shaft and a central shaft drive connection. The central shaft is provided with several blades in the circumference. The central shaft and the blades are fastened together by a bracket. The blades are arranged in an arc shape. Each blade includes a base plate, an upper sliding plate and a lower sliding plate. The upper sliding plate and the lower sliding plate are movably connected to the base plate.
[0011] The stator, equipped with coils, is mounted through a transducer cavity, while the rotor, equipped with magnets, is fixed to the input shaft. When the wind collection device collects wind energy, the staggered blades drive the central shaft to rotate, which in turn drives the input shaft and rotor to rotate. During rotor rotation, the coils on the stator cut the magnetic field lines of the magnets on the rotor, inducing a current in the coils. Two blades can be used, fixed to the central shaft by a bracket. Their staggered arrangement allows a slight breeze to apply an eccentric torque to the blades relative to the central shaft axis, causing the blades to rotate along the central shaft axis. Through this fixed connection, the central shaft rotates. The blades adopt a split design, with the substrate fixed to the central shaft by a bracket for power transmission. The upper sliding blade is located on the upper side of the substrate, and the lower sliding blade is located on the lower layer of the substrate. Through a movable connection with the substrate, when generating electricity in a light breeze, the upper and lower sliding blades are far apart from the horizontal centerline of the substrate, maintaining a large windward area and thus ensuring power generation efficiency. When the wind force increases, the upper and lower sliding blades slide towards the horizontal centerline of the substrate, reducing the windward area and preventing the blades from tipping over and being damaged by excessive wind force.
[0012] Furthermore, the central axis is fastened to the base plate by a bracket. The base plate has a sliding groove on its lower side and several sliding plates. The uppermost sliding plate is slidably connected to the sliding groove. The sliding plate has a lower contraction channel. The lower sliding plate is slidably connected to the upper lower contraction channel. The lower end of the sliding groove is inclined toward the central axis.
[0013] A limiting block can be installed at the bottom of the chute to prevent the substrate and the sliding plates from detaching. The chute guides the sliding of the uppermost sliding plate. The chute is inclined, with the lower end closer to the central axis than the upper end. All sliding plates slide parallel to the chute's inclination direction. During low-wind power generation, the sliding plates unfold sequentially under gravity, maintaining a large windward area and improving energy conversion efficiency. As the wind increases, during the rotation of the substrate and sliding plates, the substrate is fixed to the central axis by the support, while the sliding plates are subjected to centrifugal force. Through the inclined chute and lower contraction channel, when the upward component of the force along the chute exceeds the sliding plate's own weight and frictional force, the sliding plates contract towards the substrate, reducing the windward area and ensuring stable power generation.
[0014] Furthermore, the substrate has a ridge on its upper side and several upper sliding pieces. The lower end of the bottom upper sliding piece is slidably connected to the ridge. The upper sliding piece has an upper shrinkage groove. Adjacent upper sliding pieces are slidably connected through the lower upper shrinkage groove. The ridge and the upper shrinkage groove are respectively provided with pre-tightening springs. The upper end of the ridge is inclined towards the central axis. The bottom upper sliding piece is connected to the substrate through the pre-tightening spring. Adjacent upper sliding pieces are connected through the pre-tightening spring.
[0015] Because the upwardly extending sliding plate tends to contract under the influence of gravity, a pre-tensioning spring is installed through the upper contraction groove and ridge. This allows the spring force of the pre-tensioning spring to overcome the weight of the upper sliding plate and maintain its extended state. The spring force of the pre-tensioning spring increases sequentially from top to bottom. When the downward tilting force generated by centrifugal force and the weight of the sliding plate exceed the spring force of the pre-tensioning spring and the frictional force, the sliding plate contracts towards the substrate, reducing the windward area. In other words, when the wind force is too strong, the upper sliding plate can contract towards the substrate to ensure the stability of power generation.
[0016] Furthermore, the upper shrinkage groove is located in the middle of the upper slide plate, and the lower shrinkage channel is located on both sides of the lower slide plate.
[0017] The upper shrinkage groove is located in the middle for sliding guidance, which facilitates the installation of the pre-tightening spring. The lower shrinkage channel is located on both sides of the lower slide plate for sliding guidance.
[0018] Furthermore, the air collection device also includes a monitoring component, which is electrically connected to the stator. The input shaft is provided with a guide groove, and the lower end of the central shaft is inserted into the guide groove.
[0019] By setting up monitoring components to detect power generation efficiency, the generator generates electricity with a large windward area during the micro-wind power generation process. When the wind force is too strong, the instantaneous power generation increases. The lower end of the input shaft is inserted into the guide groove, which causes the central shaft to drive the substrate to move downward. By moving the center of gravity downward, the power generation stability is ensured.
[0020] Furthermore, the monitoring component includes a locking block and an electromagnet. A receiving groove is provided on the central shaft. The locking block and the receiving groove are slidably connected. A locking spring is provided inside the locking block. The locking block is made of magnetic material. The end of the locking spring abuts against the wall of the receiving groove. A slot is provided on the input shaft, and the electromagnet is placed in the slot.
[0021] Initially: The two ends of the card block are inserted into the receiving slot and the card slot respectively.
[0022] In the initial state, the locking blocks are inserted into the receiving slot and the locking groove respectively by the spring force of the locking spring, so that the central shaft and the input shaft remain relatively fixed, and the central shaft maintains a large elongation in the guide groove, which is convenient for micro wind power generation.
[0023] Furthermore, the circuit connecting the electromagnet and the stator is electrically connected;
[0024] During adjustment: the opposing ends of the locking block and the electromagnet are the same magnetic poles, and the central shaft and the guide groove are slidably connected.
[0025] When the wind force is too strong, the current generated by the coils on the stator cutting the magnetic field lines increases, that is, the instantaneous current of the power generation circuit increases. When the instantaneous current is too large, the repulsive force between the electromagnet and the locking block overcomes the elastic force of the locking spring, causing the locking block to shrink towards the receiving groove. Under the action of gravity, the central shaft moves down along the guide groove, lowering the center of gravity, thereby improving the stability of power generation.
[0026] As an optimization, the cross-sectional area enclosed by the inner sides of the bottommost sliding plates is larger than the cross-sectional area of the base. When the central axis moves to the bottom of the guide groove, the difference in cross-section ensures that the base will not interfere with the sliding plates, while the base also provides partial wind protection to ensure power generation stability.
[0027] Compared with existing technologies, the advantages of this invention are: It automatically collects light winds through a wind-collecting device and transmits the energy to a transducer, converting its mechanical energy into electrical energy and storing it. The windward area can be adjusted according to different wind conditions, thereby improving conversion stability. Simultaneously, it intelligently detects wind force and switches modes when the wind is too strong to avoid damage. The blades adopt a split design, with the substrate fixed to the central shaft by a bracket for power transmission. The upper sliding plate is located on the upper side of the substrate, and the lower sliding plate is located on the lower layer of the substrate. Through a movable connection with the substrate, during light wind power generation, the upper and lower sliding plates are further apart from the horizontal centerline of the substrate, maintaining a larger windward area. This ensures power generation efficiency. When the wind increases, the upper and lower sliding plates slide towards the horizontal centerline of the substrate, reducing the windward area and preventing the main body from tipping over due to excessive wind force. During micro-wind power generation, due to the low wind force, the lower sliding plates unfold sequentially under the action of gravity, maintaining a large windward area and thus improving energy conversion efficiency. As the wind force increases, during the rotation of the substrate and lower sliding plates, since the substrate is fixed on the central axis by the support, the lower sliding plates are subjected to centrifugal force. Through the inclined sliding grooves and lower contraction channels, when the component force on the lower sliding plate inclined upward along the sliding groove is greater than its own weight and the frictional force, it contracts towards the substrate, thereby reducing the windward area and ensuring the stability of power generation.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] Example: Figures 1-6 As shown, the present invention provides a micro wind turbine technology solution with intelligent monitoring function.
[0037] The micro wind generator includes a housing 1, a transducer 2, a wind collector 3, and a base 4. The base 4 is provided with a mounting groove, the housing 1 is placed in the mounting groove, the transducer 2 is connected to the housing 1, the wind collector 3 is connected to the transducer 2, and the wind collector 3 is used to adjust the windward area.
[0038] The base 4 serves as the main support foundation, installed on the ground, and the casing 1 is installed through the mounting slot. The casing is used to install the energy transducer 2. The wind collection device 3 automatically collects the breeze and transmits it to the energy transducer 2, converting its mechanical energy into electrical energy and storing it. It is conventionally used for wind power generation. However, due to the low-altitude power generation, the airflow field is complex and the wind force is not constant due to the influence of ground forces. During disaster relief, the windward area can be adjusted according to different wind conditions to improve the conversion stability. At the same time, the wind force is intelligently detected, and when the wind force is too strong, the mode is switched to avoid damage.
[0039] Furthermore, the transducer 2 includes a stator 21, a rotor 22 and an input shaft 23. The housing 1 is provided with a transducer cavity 11. The stator 21 and the rotor 22 are respectively placed in the transducer cavity 11. The input shaft 23 is rotatably connected to the transducer cavity 11. One end of the input shaft 23 passes through the transducer cavity 11. The rotor 22 is fastened to the input shaft 23. One end of the input shaft 23 is connected to the air collecting device 3.
[0040] The air collection device 3 includes a central shaft 32, an input shaft 23 and a central shaft 32 are connected by a drive. The central shaft 32 is provided with a number of blades 31 in the circumference. The central shaft 32 and the blades 31 are fastened together by a bracket. The blades 31 are arranged in an arc shape. Each blade 31 includes a base plate 311, an upper sliding plate 312 and a lower sliding plate 313. The upper sliding plate 312 and the lower sliding plate 313 are respectively movably connected to the base plate 311.
[0041] The stator 21, equipped with coils, is mounted through the transducer cavity 11. The rotor 22, equipped with magnets, is fixed to the input shaft 23. When the wind collection device 3 collects wind energy, the offset blades 31 drive the central shaft 32 to rotate, thereby sequentially driving the input shaft 23 and the rotor 22 to rotate. During the rotation of the rotor 22, the coils on the stator 21 cut the magnetic field lines of the magnets on the rotor 22, thus generating an induced current in the coils. Two blades 31 can be used, fixed to the central shaft 32 by a bracket. Through their staggered arrangement, a slight breeze applies an eccentric torque to the blades 31 relative to the axis of the central shaft 32, thereby driving the blades 31 to rotate along the axis of the central shaft 32. Through the fixed connection, the central shaft 32 is driven to rotate. The blade 31 adopts a split design, in which the substrate 311 is fixed on the central shaft 32 by a bracket for power transmission. The upper sliding blade 312 is located on the upper side of the substrate 311, and the lower sliding blade 313 is located on the lower layer of the substrate 311. Through the movable connection with the substrate 311, when generating electricity in a light breeze, the upper sliding blade 312 and the lower sliding blade 313 are far away from each other relative to the horizontal centerline of the substrate 311, maintaining a large windward area and thus ensuring power generation efficiency. When the wind force increases, the upper sliding blade 312 and the lower sliding blade 313 slide towards the horizontal centerline of the substrate 311, reducing the windward area and preventing the main body from tipping over and being damaged by excessive wind force.
[0042] Furthermore, the central shaft 32 is fastened to the base plate 311 by the bracket. The base plate 311 is provided with a groove 3111 on the lower side. Several lower slide plates 313 are provided. The uppermost lower slide plate 313 is slidably connected to the groove 3111. The lower slide plate 313 is provided with a lower contraction channel 3131. The lower slide plate 313 is slidably connected to the upper lower contraction channel 3131. The lower end of the groove 3111 is inclined toward the central shaft 32.
[0043] A limiting block can be set at the bottom of the slide 3111 to limit the movement and prevent the substrate 311 and the slide plate 313 from separating. By setting a sliding groove 3111 to guide the uppermost sliding plate 313, the sliding groove 3111 is arranged at an angle, with the lower end closer to the central axis 32 than the upper end. The sliding trajectory of all the sliding plates 313 is parallel to the tilt direction of the sliding groove 3111. When generating electricity in a light breeze, due to the low wind force, the sliding plates 313 unfold sequentially under the action of gravity, maintaining a large windward area, thereby improving energy conversion efficiency. As the wind force increases, during the rotation of the substrate 311 and the sliding plates 313, since the substrate 311 is fixed on the central axis 32 by the support, the sliding plates 313 are subjected to centrifugal force. Through the inclined sliding groove 3111 and the lower contraction channel 3131, when the component force of the sliding plate 313 tilting upward along the sliding groove 3111 is greater than its own weight and the frictional force it receives, it contracts towards the substrate 311, thereby reducing the windward area and ensuring the stability of power generation.
[0044] Furthermore, the substrate 311 has a ridge 3112 on its upper side, and several upper sliding pieces 312 are provided. The lower end of the bottom upper sliding piece 312 is slidably connected to the ridge 3112. The upper sliding piece 312 is provided with an upper shrinkage groove 3121. Adjacent upper sliding pieces 312 are slidably connected through the lower upper shrinkage groove 3121. The ridge 3112 and the upper shrinkage groove 3121 are respectively provided with a pre-tension spring 314. The upper end of the ridge 3112 is inclined toward the central axis 32. The bottom upper sliding piece 312 is connected to the substrate 311 through the pre-tension spring 314. Adjacent upper sliding pieces 312 are connected through the pre-tension spring 314.
[0045] Since the upwardly extending sliding plate 312 tends to contract under the influence of gravity, the pre-tensioning spring 314 is installed through the upper contraction groove 3121 and the ridge 3112, so that the elastic force of the pre-tensioning spring 314 can overcome the self-weight of the upper sliding plate 312 and maintain the extended state. The elastic force of the pre-tensioning spring 314 increases from top to bottom. When the downward tilting force generated by centrifugation and the self-weight are greater than the elastic force and friction of the pre-tensioning spring 314, it contracts towards the base plate 311 to reduce the windward area. That is, when the wind force is too strong, the upper sliding plate 312 can contract towards the base plate 311 to ensure the stability of power generation.
[0046] Furthermore, the upper shrinkage groove 3121 is located in the middle of the upper slide plate 312, and the lower shrinkage channel 3131 is located on both sides of the lower slide plate 313.
[0047] The upper shrinkage groove 3121 is located in the middle and serves as a sliding guide, facilitating the installation of the pre-tension spring 314. The lower shrinkage channel 3131 is located on both sides of the lower slide plate 313 and serves as a sliding guide.
[0048] Furthermore, the air collection device 3 also includes a monitoring component 33, which is electrically connected to the stator 21. The input shaft 23 is provided with a guide groove 232, and the lower end of the central shaft 32 is inserted into the guide groove 232.
[0049] The power generation efficiency is detected by setting the monitoring component 33. During the micro-wind power generation process, the power generation is carried out with a large windward area. When the wind force is too strong, the instantaneous power generation increases. The lower end of the input shaft 23 is inserted into the guide groove 232, which causes the central shaft 32 to drive the substrate 311 to move down. By moving the center of gravity down, the power generation stability is ensured.
[0050] Furthermore, the monitoring component 33 includes a locking block 332 and an electromagnet 333. A receiving groove 321 is provided on the central shaft 32. The locking block 332 and the receiving groove 321 are slidably connected. A locking spring 331 is provided inside the locking block 332. The locking block 332 is made of magnetic material. The end of the locking spring 331 abuts against the wall of the receiving groove 321. A slot 231 is provided on the input shaft 23. The electromagnet 333 is placed in the slot 231.
[0051] Initially: The two ends of the card block 332 are inserted into the receiving slot 321 and the card slot 231 respectively.
[0052] In the initial state, the locking block 332 is inserted into the receiving groove 321 and the locking groove 231 respectively by the elastic force of the locking spring 331, so that the central shaft 32 and the input shaft 23 remain relatively fixed, and the central shaft 32 maintains a large extension in the guide groove 232, which is convenient for micro-wind power generation.
[0053] Furthermore, the circuit connecting electromagnet 333 and stator 21 is electrically connected;
[0054] During adjustment: the opposite ends of the locking block 332 and the electromagnet 333 are the same magnetic poles, and the central shaft 32 and the guide groove 232 are slidably connected.
[0055] When the wind force is too strong, the current generated by the coil on the stator 21 cutting the magnetic field lines increases, that is, the instantaneous current of the power generation circuit increases. When the instantaneous current is too large, the repulsive force between the electromagnet 333 and the locking block 332 overcomes the elastic force of the locking spring 331, causing the locking block 332 to shrink towards the receiving groove 321. Under the action of gravity, the central shaft 32 moves down along the guide groove 232, lowering the center of gravity, thereby improving the stability of power generation.
[0056] As an optimization, the cross-sectional area enclosed by the inner sides of the bottommost sliding plates 313 is larger than the cross-sectional area of the base 4. When the central axis 32 moves to the bottom of the guide groove 232, the difference in cross-section ensures that the base 4 will not interfere with the sliding plates 313, while the base 4 provides partial wind protection to ensure power generation stability.
[0057] The working principle of this invention is as follows: A gentle breeze is automatically collected by the wind collection device 3 and transmitted to the energy conversion device 2, where its mechanical energy is converted into electrical energy and stored. The windward area can be adjusted according to different wind conditions to improve conversion stability. Simultaneously, the wind force is intelligently detected, and when the wind force is too strong, the mode is switched to avoid damage. The blade 31 adopts a split design, where the substrate 311 is fixed to the central shaft 32 by a bracket for power transmission. The upper sliding blade 312 is located on the upper side of the substrate 311, and the lower sliding blade 313 is located on the lower layer of the substrate 311. Through a movable connection with the substrate 311, during wind power generation, the upper sliding blade 312 and the lower sliding blade 313 are further away from the horizontal centerline of the substrate 311, maintaining a larger windward area and thus ensuring power generation efficiency. When the wind increases, the upper sliding plate 312 and the lower sliding plate 313 slide towards the horizontal centerline of the substrate 311, reducing the windward area and preventing the main body from tipping over and being damaged by excessive wind. When generating electricity in a light breeze, due to the low wind speed, the lower sliding plate 313 unfolds sequentially under the action of gravity, maintaining a large windward area and thus improving energy conversion efficiency. As the wind speed increases, during the rotation of the substrate 311 and the lower sliding plate 313, since the substrate 311 is fixed on the central shaft 32 by the support, the lower sliding plate 313 is subjected to centrifugal force. Through the inclined sliding groove 3111 and the lower contraction channel 3131, when the component force of the lower sliding plate 313 inclined upward along the sliding groove 3111 is greater than its own weight and the frictional force it receives, it contracts towards the substrate 311, thereby reducing the windward area and ensuring the stability of power generation.
