Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and more particularly to a dual-purpose fan for generating electricity through fanning. Background Art

[0002] In some outdoor resting places or densely populated areas, large vertical fans have become indispensable ventilation and heat dissipation equipment. They use motors to drive the fan blades to rotate, effectively alleviating the discomfort caused by hot weather. In order to further improve the practicality and energy efficiency of such fans, the prior art converts fans into wind power generation devices. For example, a vertical fan disclosed in a Chinese patent (application number: 202110004314.9) cleverly utilizes natural wind resources. When the natural wind blows the fan blades, the output shaft of the motor can rotate, thereby realizing motor power generation and storing the generated electrical energy. When ventilation and heat dissipation are required, the stored electrical energy is used to power the motor. This design greatly saves energy and improves the environmental performance of the fan.

[0003] However, in practical applications, this type of wind power generation also faces some challenges. Since the wind speed of natural wind is constantly changing, sometimes gentle and sometimes fierce, this poses a considerable test to the fan's power generation system. Especially when the wind speed is too high, the fan blades will rotate too fast, which will not only cause a sharp increase in the power generation of the motor, easily causing the motor to be in an overload state and shortening its service life; the high-speed rotation of the fan blades will also cause violent vibration of the overall structure of the fan, which may cause damage to the overall structure of the fan in the long run and even cause safety hazards.

[0004] In view of the above-mentioned problems, the present invention has carried out targeted improvements and optimizations based on in-depth analysis and research on the existing dual-purpose fan technology, aiming to develop a dual-purpose fan for fanning and generating electricity. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a dual-purpose fan for fanning and generating electricity, which can automatically adjust the opening size of the air vent, thereby regulating the force of the wind acting on the air vent, and flexibly change the rotation speed of the fan blades and the outer rotor to ensure that the outer rotor can maintain operation within a stable speed range. It can effectively ensure that the outer rotor motor can generate electricity continuously and stably, avoid damage due to overload problems during the power generation process, and reduce the violent shaking of the whole equipment caused by the excessive speed of the fan blades, thereby preventing the risk of loosening or disintegration of the equipment structure.

The motor drives the winding wheel to rotate, and the traction rope is pulled by the rotation of the winding wheel, and then the traction rope drives the extrusion plate to swing up and down to squeeze the opening of the scoop piece.

[0008] Furthermore, the fan blade is designed with a hollow structure, the traction rope is arranged at the hollow structure of the fan blade, one end of the extrusion plate extends into the hollow structure of the fan blade, and the lower end of the extrusion plate is close to the inner bottom wall of the fan blade, the extrusion plate is located at the hollow structure of the fan blade and is fixedly installed with a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the fan blade, a spring is fixedly connected to the inner wall of the upper end of the fan blade, the lower end of the spring is fixedly connected to the extrusion plate, a wire wheel is installed on the inner wall of the fan blade near the upper end, the traction rope is fixedly connected to the lower end of the extrusion plate, the traction rope passes through the upper end of the wire wheel, a horizontal plate is fixedly installed on the inner wall of the control box at a position above the winding wheel, the traction rope passes movably through the inside of the horizontal plate, and the wind-shaking piece is made of elastic material.

[0009] Further, including: A cover plate, the cover plate being fixedly mounted on the upper end of the central shaft; An anemometer, which is installed at the upper end of the cover plate and is used to collect wind speed data at the current moment in real time; A speed sensor, which is installed at the lower end of the cover plate and is used to monitor the speed data of the outer rotor in real time; The processing module calculates the rotation amplitude of the motor-driven winding wheel according to the rotation speed data collected by the speed sensor and the wind speed data collected by the anemometer.

[0010] Furthermore, according to the rotation speed data collected by the speed sensor and the wind speed data collected by the anemometer, the amplitude of the motor-driven winding wheel rotation is calculated, including: Presetting the stable speed of the outer rotor of the outer rotor motor when generating electricity; If the current speed of the outer rotor is not within the preset stable speed, the processing module first determines whether the speed of the outer rotor is less than the preset stable speed or greater than the preset stable speed; If the speed of the outer rotor is greater than the preset stable speed, the processing module controls the motor to rotate forward, so that the winding wheel rotates and tightens the traction rope, and drives the extrusion plate to deflect downward to squeeze the opening of the wind-up piece, so that the opening of the wind-up piece becomes smaller and the speed of the outer rotor is reduced, until the outer rotor stabilizes within the preset stable speed, and stops the motor from driving the winding wheel to rotate; If the speed of the outer rotor is lower than the preset stable speed, the processing module controls the motor to reverse, causing the winding wheel to rotate and loosen the traction rope, and drives the extrusion plate to deflect upward and loosen the opening of the wind-up piece, so that the opening of the wind-up piece becomes larger and the speed of the outer rotor is increased until the outer rotor stabilizes within the preset stable speed, and stops the motor from driving the winding wheel to rotate.

The new learning model is used to predict the future wind speed to obtain new predicted wind speed data.

[0013] Furthermore, presetting the stable speed of the outer rotor motor when generating electricity includes: The stable speed is divided into primary speed and secondary speed, where the primary speed is the preferred speed and the secondary speed is the alternative speed when the primary speed cannot be reached; The actual speed of the current outer rotor is monitored in real time and compared with the preset first-level speed. If the actual speed is lower than the first-level speed, the processing module enters the speed adjustment process and adjusts the speed of the outer rotor to the first-level speed by controlling the opening size of the ventilator.

[0022] See also Figures 1 to 6 A dual-purpose fan for fanning and power generation, comprising a column 1 and a base 2, wherein the base 2 is fixedly mounted at the lower end of the column 1; an outer rotor motor 3, wherein the outer rotor motor 3 is composed of a central axis 31 and an outer rotor 32, wherein the central axis 31 is arranged inside the outer rotor 32, and the upper and lower ends of the central axis 31 penetrate the outer rotor 32 and extend to the outside, and the lower end of the central axis 31 is fixedly connected to the column 1; blades 4, wherein the blades 4 are arranged in multiple groups, wherein the multiple groups of blades 4 are fixedly mounted on the outer surface of the outer rotor 32, and wherein the multiple groups of blades 4 are evenly distributed in a ring shape; a wind-shaking member 5, wherein the wind-shaking member 5 is mounted at one end of the blade 4 away from the outer rotor 32; a support plate 12, wherein the support plate 12 is fixedly connected to the lower surface of the wind-shaking member 5, and the support plate One end of 12 is fixedly connected to the fan blade 4; the extrusion plate 11, the extrusion plate 11 is arranged on the top of the wind-blowing member 5; the control box 6, the control box 6 is installed on the lower surface of the outer rotor 32; the motor 7, the motor 7 is installed in the control box 6; the winding wheel 8, the winding wheel 8 is fixedly installed on the output shaft of the motor 7; the traction rope 10, the number of the traction ropes 10 corresponds to the number of the extrusion plates 11, one end of the traction rope 10 is fixedly connected to the winding wheel 8, and the end of the traction rope 10 away from the winding wheel 8 is connected to the extrusion plate 11, the motor 7 drives the winding wheel 8 to rotate, and the traction rope 10 is pulled by the rotation of the winding wheel 8, and then the traction rope 10 drives the extrusion plate 11 to swing up and down to squeeze the opening of the wind-blowing member 5; The fan blade 4 is designed with a hollow structure. The traction rope 10 is arranged at the hollow structure of the fan blade 4. One end of the extrusion plate 11 extends into the hollow structure of the fan blade 4, and the lower end of the extrusion plate 11 is close to the inner bottom wall of the fan blade 4. The extrusion plate 11 is located at the hollow structure of the fan blade 4 and is fixedly installed with a rotating shaft 13. The rotating shaft 13 is rotatably connected to the inner wall of the fan blade 4. The upper inner wall of the fan blade 4 is fixedly connected with a spring 14. The lower end of the spring 14 is fixedly connected to the extrusion plate 11. A wire wheel 15 is installed near the upper end of the inner wall of the fan blade 4. The traction rope 10 is fixedly connected to the lower end of the extrusion plate 11. The traction rope 10 passes through the upper end of the wire wheel 15. The inner wall of the control box 6 is located above the winding wheel 8 and is fixedly installed with a horizontal plate 9. The traction rope 10 passes through the inside of the horizontal plate 9. The wind-shaking member 5 is made of elastic material. A battery is installed in the base 2, and the battery is electrically connected to the outer rotor motor 3. The battery provides driving power for the outer rotor motor 3. A voltage stabilizing module and a boost module are installed in the base 2. When the outer rotor motor 3 generates electricity, the voltage is stabilized by the voltage stabilizing module, and then the battery is charged by the boost module.

[0023] Through the above technical solution, when fanning is required, the outer rotor motor 3 is turned on, the battery supplies power to the outer rotor motor 3, and drives the outer rotor 32 to rotate. When the outer rotor 32 rotates, it drives the fan blades 4 to rotate. When the fan blades 4 rotate, they drive the airflow to flow downward, thereby realizing a cooling operation for people standing next to the column 1. The fan blades 4 and the outer rotor 32 of the present invention are fixed by bolts. When there is natural wind outside, the flowing air will blow the opening of the wind-shaking member 5, and the wind-shaking member 5 will move under the blowing force of the wind and drive the fan blades 4 to move. The outer rotor 32 is driven to rotate by the fan blades 4, and the magnetic flux lines are cut between the outer rotor 32 and the central axis 31, thereby generating current. The current will pass through the voltage stabilizing module and the boosting module in turn and finally enter the battery to realize charging of the battery. By self-generating and storing, energy saving is realized to a certain extent.

[0024] When the external wind force is strong, the motor 7 drives the winding wheel 8 to rotate forward, and the traction rope 10 is wound on the winding wheel 8 to pull the traction rope 10. When the traction rope 10 is pulled, it will also drive the extrusion plate 11. When the extrusion plate 11 is pulled, it will rotate with the rotating shaft 13 as the rotating point. At this time, the left part of the extrusion plate 11 located on the rotating shaft 13 will deflect upward and squeeze the spring 14. The part of the extrusion plate 11 located on the right side of the rotating shaft 13 will deflect downward. The right side of the extrusion plate 11 and the support plate 12 will cooperate to squeeze the air vent member 5, thereby making the opening of the air vent member 5 smaller. This can reduce the action area of ​​the airflow on the air vent member 5, reduce the action force of the airflow on the air vent member 5, thereby reducing the rotation speed of the air vent member 5 and the fan blade 4, and then reduce the rotation speed of the outer rotor 32, avoid the problem of power generation overload caused by excessive rotation speed of the outer rotor motor 3, and also avoid the problem of overall shaking and falling apart due to excessive rotation speed of the fan blade 4. When the external wind force is relatively small, and the opening of the ventilating piece 5 is not fully opened, the motor 7 drives the winding wheel 8 to rotate in the opposite direction to loosen the traction rope 10, and the previously compressed spring 14 will push the extrusion plate 11 located on the left side of the rotating shaft 13 to rotate downward, while the extrusion plate 11 located on the right side of the rotating shaft 13 rotates upward, and the extrusion plate 11 will gradually loosen the opening of the ventilating piece 5. Because the ventilating piece 5 is made of elastic material, the opening of the ventilating piece 5 that was squeezed before will become larger, increasing the contact area with the airflow, thereby increasing the force of the airflow on the ventilating piece 5, to increase the rotation speed of the fan blades 4 and the outer rotor 32, and maintain the outer rotor 32 in a stable rotation speed state as much as possible, to ensure that the outer rotor motor 3 can generate electricity stably.

[0025] In a preferred embodiment of the present invention, it includes a cover plate 16, which is fixedly mounted on the upper end of the central axis 31; an anemometer 17, which is mounted on the upper end of the cover plate 16, and is used to collect wind speed data at the current moment in real time; a speed sensor 21, which is mounted on the lower end of the cover plate 16, and is used to monitor the rotation speed data of the outer rotor 32 in real time; and a processing module, which calculates the amplitude of the rotation of the winding wheel 8 driven by the motor 7 according to the rotation speed data collected by the speed sensor 21 and the wind speed data collected by the anemometer 17.

[0026] According to the rotation speed data collected by the speed sensor 21 and the wind speed data collected by the anemometer 17, the amplitude of the rotation of the winding wheel 8 driven by the motor 7 is calculated, including: Presetting the stable rotation speed of the outer rotor 32 when the outer rotor motor 3 generates electricity; If the current speed of the outer rotor 32 is not within the preset stable speed, the processing module first determines whether the speed of the outer rotor 32 is less than the preset stable speed or greater than the preset stable speed; If the speed of the outer rotor 32 is greater than the preset stable speed, the processing module controls the motor 7 to rotate forward, so that the winding wheel 8 rotates and tightens the traction rope 10, and drives the extrusion plate 11 to deflect downward to squeeze the opening of the winder 5, so that the opening of the winder 5 becomes smaller and the speed of the outer rotor 32 is reduced, until the outer rotor 32 stabilizes within the preset stable speed, and stops the motor 7 from driving the winding wheel 8 to rotate; If the rotation speed of the outer rotor 32 is lower than the preset stable rotation speed, the processing module controls the motor 7 to reverse, so that the winding wheel 8 rotates to loosen the traction rope 10, and drives the extrusion plate 11 to deflect upward to loosen the opening of the ventilating piece 5, so that the opening of the ventilating piece 5 becomes larger to increase the rotation speed of the outer rotor 32, until the outer rotor 32 stabilizes within the preset stable rotation speed, and stops the motor 7 from driving the winding wheel 8 to rotate.

[0027] Through the above technical solution, the processing module monitors the rotation speed of the outer rotor 32 in real time through the speed sensor 21, and the processing module will determine whether the rotation speed of the outer rotor 32 is higher or lower than the preset value. The preset value is a stable rotation speed interval of the outer rotor 32 set according to the performance of the outer rotor motor 3. This interval is the optimal speed range for the outer rotor motor 3 to operate efficiently and stably. If the rotation speed of the outer rotor 32 is higher than the preset value, the processing module controls the motor 7 to rotate forward, and the forward rotating motor 7 drives the winding wheel 8 to rotate. The winding wheel 8 tightens the traction rope 10, and the tension of the traction rope 10 is transmitted to the winder 5 through the extrusion plate 11, so that its opening becomes smaller. The winder 5 with a smaller opening has a weakened ability to capture wind energy, which will reduce the rotation speed of the fan blades 4, thereby reducing the rotation speed of the outer rotor 32, ensuring that the outer rotor motor 3 is at a stable speed for stable power generation.

[0028] If the speed of the outer rotor 32 is lower than the preset value, the processing module controls the motor 7 to reverse, and the reversed motor 7 causes the winding wheel 8 to release the traction rope 10, the tension of the traction rope 10 is reduced, the squeezing effect of the squeezing plate 11 on the wind-up piece 5 is weakened, and the opening of the wind-up piece 5 becomes larger. The ability of the wind-up piece 5 with a larger opening to capture wind energy is enhanced, thereby increasing the speed of the outer rotor 32 and ensuring that the outer rotor motor 3 is within a stable speed for stable power generation. By automatically adjusting the opening size of the wind-up piece 5, the speed of the outer rotor 32 can be finely controlled, and the outer rotor motor 3 can be ensured to be within a stable speed as much as possible for stable power generation, thereby ensuring the effective power generation of the outer rotor motor 3. The power generation system of the present invention can automatically monitor and adjust the speed of the outer rotor 32 without manual intervention, thereby improving the automation and stability of the system.

[0029] In a preferred embodiment of the present invention, the amplitude of the motor 7 driving the winding wheel 8 to rotate is calculated based on the rotation speed data collected by the speed sensor 21 and the wind speed data collected by the anemometer 17, and further includes: The processing module records the collected wind speed data in real time and stores it as historical data. The processing module uses a learning model to analyze the historical wind speed data to predict the wind speed data at the next moment. According to the predicted wind speed data and the current opening state of the wind-shaking member 5, it is predicted whether the speed of the outer rotor 32 at the next moment is within the stable speed. If the predicted speed of the outer rotor 32 is greater than the stable speed, the processing module drives the motor 7 to rotate, and controls the opening of the air vent 5 to become smaller to the target state; If the predicted rotation speed of the outer rotor 32 is lower than the stable rotation speed, the processing module drives the motor 7 to rotate, and controls the opening of the air vent 5 to become larger to the target state.

[0030] Through the above technical solution, the speed sensor 21 collects the speed data of the outer rotor 32 in real time, and the anemometer 17 collects the current wind speed data at the same time. The processing module stores these data together with the timestamp in the database to form a historical data set. The processing module uses the learning model to analyze the historical wind speed data, and predicts the wind speed at the next moment through the learning model based on the current and recent wind speed data. The learning model combines the predicted wind speed data and the current opening state of the wind vent 5 to predict the speed of the outer rotor 32 at the next moment. If the predicted speed of the outer rotor 32 is greater than the stable speed, the processing module drives the motor 7 to rotate and controls the opening of the wind vent 5 to become smaller to the target state; If the predicted rotation speed of the outer rotor 32 is lower than the stable rotation speed, the processing module drives the motor 7 to rotate, and controls the opening of the air vent 5 to become larger to the target state.

[0031] The above-mentioned learning model can be a time series analysis model or a neural network model, wherein the time series analysis model can be an autoregressive integrated moving average model (ARIMA) or an exponential smoothing model, and wherein the neural network model can be a recurrent neural network (RNN) or a long short-term memory network (LSTM).

[0032] In a preferred embodiment of the present invention, the amplitude of the motor 7 driving the winding wheel 8 to rotate is calculated based on the rotation speed data collected by the speed sensor 21 and the wind speed data collected by the anemometer 17, and further includes: Compare the predicted wind speed data with the wind speed data at the current moment; The difference between the predicted wind speed data and the wind speed data at the previous moment is calculated, and the difference is used as a feedback signal to adjust the learning model to obtain a new learning model. The new learning model is used to predict future wind speeds. The predicted model is automatically adjusted according to the difference so that the subsequent predicted wind speed data tends to be the same as the wind speed data at the previous moment. The new learning model is used to predict the future wind speed to obtain new predicted wind speed data.

[0033] Through the above technical solution, the current learning model (such as a time series analysis model, a neural network model) is used to analyze the current and recent wind speed data based on the historical wind speed data, and the wind speed at the next moment is predicted. The wind speed data at the current moment is compared with the predicted wind speed data, and the difference between the actual wind speed data and the predicted wind speed data is calculated. This difference reflects the accuracy of the learning model prediction. The calculated difference is used as a feedback signal, which is used to adjust the parameters of the learning model to improve its prediction performance. After adjusting the learning model according to the feedback signal, a new learning model is obtained, and the new learning model is used to predict the future wind speed to obtain new predicted wind speed data. The above steps are repeated, that is, the new predicted wind speed data is compared with the wind speed data at the current moment, the difference is calculated, a feedback signal is generated, the model is adjusted, and the prediction is re-set. A convergence standard (such as a prediction error is less than a certain threshold) is set. When the convergence standard is met, the learning model is considered to be sufficiently accurate, and the iteration is stopped at this time.

[0034] In a preferred embodiment of the present invention, the stable speed of the outer rotor motor 3 when generating electricity is pre-set, including: The stable speed is divided into primary speed and secondary speed, where the primary speed is the preferred speed and the secondary speed is the alternative speed when the primary speed cannot be reached; The actual speed of the current outer rotor 32 is monitored in real time and compared with the preset first-level speed. If the actual speed is lower than the first-level speed, the processing module enters the speed adjustment process and adjusts the speed of the outer rotor 32 to the first-level speed by controlling the opening size of the air vent 5; If the processing module cannot adjust the speed of the outer rotor 32 to the primary speed, it automatically switches to the secondary speed adjustment mode. In the secondary speed adjustment mode, the processing module adjusts the speed of the outer rotor 32 to approach the primary speed.

[0035] Through the above technical solution, the first-level speed is an ideal speed range, such as between 2000 rpm and 2500 rpm, and the second-level speed is an alternative speed range when the first-level speed cannot be reached, such as between 1500 rpm and 2000 rpm and between 2500 rpm and 3000 rpm. The processing module compares the speed of the outer rotor 32 monitored in real time with the preset first-level speed range. If the actual speed of the outer rotor 32 is not within the first-level speed range, the processing module enters the speed adjustment process, and adjusts the wind resistance of the outer rotor 32 by controlling the opening size of the wind scoop 5, thereby trying to increase the speed of the outer rotor 32 to within the first-level speed range. If the processing module cannot adjust the speed of the outer rotor 32 to within the first-level speed range after control and adjustment, it automatically switches to the second-level speed adjustment mode. In this mode, the processing module will select a closest and feasible speed range as a target based on the difference between the current actual speed and the primary speed, as well as the two sub-ranges of the secondary speed, and continue to control the opening size of the ventilator 5 to make the speed of the outer rotor 32 as close to the primary speed as possible, but keep it within the selected secondary speed range. This design can ensure that the outer rotor motor 3 is in the best power generation state as much as possible, while ensuring the power generation of the outer rotor motor 3 and the service life of the outer rotor motor 3.

[0036] In a preferred embodiment of the present invention, it includes an annular groove 20, which is opened on the outer surface of the column 1; a conductive ring 19, which is installed in the annular groove 20 and is electrically connected to the battery; a conductive column 18, one end of the conductive column 18 is in contact with the outer circumferential surface of the conductive ring 19, and the conductive column 18 can make a circular motion in the annular groove 20 in contact with the conductive ring 19, and the end of the conductive column 18 away from the conductive ring 19 passes through the cross plate 9 and is electrically connected to the motor 7.

[0037] When the control box 6 and the motor 7 rotate with the outer rotor 32, the conductive column 18 rotates in the annular groove 20 along the outer cylindrical surface of the conductive ring 19. When rotating, the conductive column 18 is always in contact with the conductive ring 19, that is, the conductive column 18 and the conductive ring 19 are always in electrical connection. In this way, when the motor 7 rotates with the outer rotor 32, the battery can supply power and send control signals to the motor 7 through the conductive column 18 and the conductive ring 19, thereby ensuring the normal operation of the equipment.

[0038] In a preferred embodiment of the present invention, the end of the air vent member 5 away from the opening is designed in a cone shape, and the cone head is away from the opening end of the air vent member 5. The opening direction of the air vent member 5 is opposite to the direction in which the outer rotor motor 3 drives the fan blades 4 to rotate.

[0039] When the fan blades 4 are driven to fan, it is the tapered portion of the air vent member 5 that is subject to wind resistance, not the opening. The resistance between the tapered portion of the air vent member 5 and the air is small, which can ensure that the fan blades 4 are subject to less resistance when fanning, thereby ensuring normal fanning operation.

[0040] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
