Description

Technical Field

[0001] The invention relates to the technical field of ventilators, and in particular to a fan hub with adjustable blade angles. Background Art

[0002] As an important fluid mechanical equipment, ventilators are widely used in industrial production, construction environment, tunnels, underground facilities and agriculture to ensure air circulation, improve working environment and control gas exchange. In the prior art, ventilators usually adopt a fixed blade angle design. This fixed design has the characteristics of simple structure and low manufacturing cost, so it is widely used. However, ventilators with fixed blade angles have many limitations and shortcomings in actual operation, especially for variable wind conditions and complex application environments. The fixed blade angle cannot adapt to different working requirements, thus affecting the overall efficiency and operation effect of the ventilator.

[0003] Fans with fixed blade angles are usually difficult to flexibly respond to different working conditions. In situations where the air volume demand varies greatly, the angle of the fan blades cannot be adjusted according to the actual load conditions, resulting in an ineffective match between air volume and air pressure, affecting ventilation efficiency. For example, when the ventilation demand decreases, the fixed-angle blades still maintain a high air volume output, resulting in energy waste; and when the demand increases, the fixed angle cannot increase the output and cannot meet the actual demand.

After the motor 2 16 is turned on, it drives the gear 3 17 to rotate. When the gear 3 17 rotates, it drives the gear 4 18 to rotate. When the gear 4 18 rotates, it drives the shaft 19 to rotate. When the shaft 19 rotates inside the sleeve 8, it drives the bevel gear 4 20 to rotate. When the bevel gear 4 20 rotates, it drives the bevel gear 5 21 to rotate.

By adjusting the blade 15 in real time through self-rotation, the operating efficiency of the fan under different load conditions can be effectively optimized.

[0025] Please refer to the attached Figure 2 , the outer wall of the supporting shell 4 is provided with a vent hole; Specifically, the vent holes are used for heat dissipation of motor 2 16 and motor 1 5.

[0026] Please refer to the attached Figure 8 , a fan hub control system capable of adjusting blade angles, comprising: Sensor module, used to collect wind speed, wind direction, blade stress, blade angle and rotation speed data; A controller module, connected to the sensor module, is used to analyze wind conditions based on data collected by the sensor module and execute an adaptive control strategy to determine the optimal angle of the blades; The actuator module is connected to the controller module and is used to adjust the angle of the blade according to the output instruction of the controller module.

[0027] The controller module includes an adaptive control algorithm unit, which combines the fuzzy control algorithm and the PID control algorithm to adjust the blade angle according to the real-time wind data. The fuzzy control algorithm is used to cope with large changes in wind conditions, and the PID control algorithm is used to achieve precise adjustment.

[0028] Specifically, the sensor module is used to collect real-time data related to the operation of the fan to ensure that the system can be adjusted based on environmental changes and equipment status. Specifically, it includes: Wind speed sensor: configured to collect current wind speed information and transmit the information to the controller module in real time to ensure that the control system responds quickly to changes in wind speed.

[0029] Wind direction sensor: used to detect the ambient wind direction and provide basic information for determining the optimal blade angle to ensure that the fan always operates in the direction of the wind source.

[0030] Blade stress sensor: installed at the key stress-bearing parts of the blade, such as the blade root, to detect the stress conditions of the blade under different working conditions to ensure that the blade will not be overloaded or structurally damaged when adjusting the angle.

[0031] Blade angle sensor: used to detect the current angle position of the blade in real time and feed the data back to the controller module to form a closed-loop control to improve the accuracy and reliability of regulation.

[0032] Speed ​​sensor: used to measure the speed of the fan. By combining the speed with information such as wind speed and wind direction, the angle of attack of the blades can be further optimized to prevent efficiency loss or safety problems caused by too fast or too slow speed.

[0033] Controller Module The controller module is the core part of the present invention, which is responsible for processing the data of the sensor module, executing the adaptive control algorithm, and issuing control instructions to the actuator module to adjust the blade angle. The specific components include: Industrial-grade processor: used to pre-process, analyze and calculate the received data. The processor can quickly respond to changes in the external environment and adjust the blade angle according to real-time information.

[0034] Adaptive control algorithm unit: This module combines the fuzzy control algorithm with the PID control algorithm to achieve adaptive adjustment of the fan blades. The specific description is as follows: Fuzzy control algorithm: Fuzzy control algorithm is suitable for handling drastic changes in wind speed and direction, ensuring that the system can respond quickly under uncertain and nonlinear conditions. For example, when the wind speed increases suddenly, fuzzy control can provide smooth angle adjustment to reduce the impact load on the blades and reduce fatigue damage.

[0035] PID control algorithm: The PID control algorithm is used to precisely fine-tune the blade angle to ensure that the wind turbine blades maintain the optimal angle of attack under relatively stable wind conditions to maximize energy capture efficiency. The PID controller eliminates system errors by continuously adjusting the proportional, integral and differential parameters to achieve high-precision blade angle control.

[0036] Actuator Module The actuator module is responsible for physically adjusting the angle of the blades according to the instructions of the controller module to ensure that the fan can maintain the best operating state under various wind conditions. Specifically, it includes: Servo motor: used to drive the blade to rotate around its axis to achieve angle adjustment. The servo motor has fast response characteristics and can accurately adjust the blade position according to the control command.

[0037] Gear drive system: The servo motor transmits torque to the blade through the gear drive system, enabling smooth angle adjustment. The gear drive system uses a high-precision gear set to ensure the accuracy and repeatability of the blade position during adjustment.

[0038] Angle feedback device: installed between the blade and the hub, configured to monitor the blade angle position in real time and feed the information back to the controller module to form a closed-loop adjustment control to ensure that the blade adjustment accuracy meets the set requirements.

[0039] Working process Data collection and analysis During the operation of the wind turbine, the wind speed sensor, wind direction sensor, blade stress sensor, angle sensor and speed sensor in the sensor module respectively collect corresponding operation data.

[0040] The collected data is transmitted to the controller module through the communication interface. The controller module analyzes the data to determine the current wind characteristics and the force state of the blades.

[0041] Control algorithm execution and angle determination The adaptive control algorithm unit in the controller module executes the control strategy based on the real-time wind data. First, the fuzzy control algorithm is used to quickly respond to the drastic changes in wind speed and direction and calculate the target angle range of the blades.

[0042] Next, the PID control algorithm fine-tunes the target angle based on fuzzy control, and reduces the error between the blade and the target angle through proportional, integral and differential adjustments, thereby achieving the optimal angle of attack setting and ensuring that the fan can operate efficiently.

[0043] Blade angle adjustment and closed-loop control The controller module sends specific control instructions to the actuator module based on the angle instructions calculated by the control algorithm.

[0044] After receiving the command, the servo motor drives the blades to rotate through the gear transmission system and adjusts the blades to the target angle.

[0045] The angle feedback device monitors the actual angle of the blade in real time and feeds the data back to the controller module. If a deviation is detected between the actual angle and the target angle, the controller module will execute the corresponding adjustment command until the blade angle reaches the set value, thus achieving closed-loop control.

[0046] Operation status monitoring and safety protection During the entire operation process, the safety monitoring module will continuously monitor the blade stress, fan speed and wind condition changes to ensure that the fan operates within a safe range.

[0047] When encountering extreme wind conditions (such as strong winds, typhoons, etc.), the controller module will adjust the blades to the "feather state", that is, the blades are parallel to the wind direction to reduce the windward area, protect the safety of the blades and the fan, and avoid structural damage caused by overload.

[0048] The remote monitoring module can also transmit the real-time operating status to the remote operation and maintenance platform, making it easier for operation and maintenance personnel to conduct status monitoring and fault diagnosis.

[0049] System Advantages The adaptive blade control system of the present invention can intelligently adjust the angle of the fan blades according to real-time wind condition data by combining the adaptive algorithm of fuzzy control and PID control, achieving the following beneficial effects: Energy saving and efficiency improvement: By dynamically adjusting the blade angle, the wind turbine always maintains the best operating state under various wind conditions, maximizing wind energy capture efficiency while reducing power consumption.

[0050] Reduce noise and fatigue damage: Adaptive adjustment reduces the impact and vibration of the fan in strong wind or turbulent environment, thereby significantly reducing the noise level and effectively reducing the fatigue damage of the blades and hub, extending the service life of the fan.

[0051] Intelligence and safety: By combining multiple data such as wind speed, wind direction, and rotation speed, the control system can make intelligent decisions to ensure that the wind turbine automatically takes safety measures under high wind speeds or other abnormal conditions, thereby improving the safety and reliability of the system.

[0052] A method for operating a fan hub with adjustable blade angle comprises the following steps: S1. Wind condition monitoring and data collection The sensor module starts, and the wind speed sensor, wind direction sensor, blade stress sensor, speed sensor and yaw angle sensor start working to collect the current wind speed, wind direction, blade stress, wind turbine speed and yaw angle; S2. Data processing and analysis The industrial-grade processor pre-processes the received sensor data, and the adaptive control algorithm unit analyzes the pre-processed data, including: Fuzzy control: When the wind speed and wind direction change greatly, the fuzzy control algorithm infers the reasonable blade angle based on the current wind speed and wind direction conditions and responds quickly; PID control: When the wind conditions are relatively stable, the PID control algorithm is fine-tuned to ensure the accuracy of blade angle adjustment; S3. Decision-making and blade angle adjustment The controller module generates a control instruction for adjusting the blade angle and sends it to the actuator module through the communication interface; The actuator module controls the motor 15 to start. After the motor 15 is started, it drives the gear 16 to rotate. When the gear 16 rotates, it drives the gear 2 7 to rotate. When the gear 2 7 rotates, it drives the sleeve 8 to rotate. When the sleeve 8 rotates, it drives the bevel gear 10 to rotate. When the bevel gear 10 rotates inside the supporting housing 9, it drives the bevel gear 2 11 to rotate. When the bevel gear 2 11 rotates, it drives the adjusting housing 12 to rotate. When the adjusting housing 12 rotates, it drives the overall angle of the sleeve 13 to adjust. The actuator module then controls motor 2 16 to turn on. After motor 2 16 is turned on, it will drive gear 3 17 to rotate. When gear 3 17 rotates, it will drive gear 4 18 to rotate. When gear 4 18 rotates, it will drive shaft 19 to rotate. When shaft 19 rotates inside sleeve 8, it will drive bevel gear 4 20 to rotate. When bevel gear 4 20 rotates, it will drive bevel gear 5 21 to rotate. When bevel gear 5 21 rotates, it will drive gear 5 22 to rotate. When gear 5 22 rotates, it will drive gear 6 23 to rotate. When gear 6 23 rotates, it will drive connecting shaft 24 to rotate. When connecting shaft 24 rotates inside adjusting housing 12, it will drive bevel gear 8 29 to rotate. When bevel gear 8 29 is driven to rotate by connecting shaft 24, it will drive bevel gear 6 25 to rotate. When bevel gear 6 25 rotates, it will drive adjusting shaft 26 and bevel gear 7 27 to rotate. When bevel gear 7 27 rotates inside sleeve 13, it will drive bevel gear 3 14 and blade 15 to rotate. The angle of blade 15 itself is adjusted when it rotates.

[0053] Specifically, the control system collects data such as wind speed and direction through the sensor module, and dynamically adjusts the angle of the blades in combination with the up and down angle adjustment and blade rotation adjustment, so that the fan always maintains the best working state. This can maximize the capture of wind energy and improve the ventilation effect.

[0054] The control system adjusts the blade's up and down angle and rotation angle in real time based on the ambient wind conditions and the fan's operating parameters, thereby accurately controlling the direction and volume of the airflow. This precise airflow management can effectively improve the fan's overall output performance, making it perform well in different application scenarios.
