Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation equipment, and in particular to a deicing device and method for wind turbine blades in high-cold mountainous areas. Background Art

[0002] In recent years, the development of wind resources in plain areas has gradually become saturated, and the site selection of wind farms tends to be more complex terrains with higher altitudes. At present, the widely available wind resources in my country are mainly distributed in the three northern regions and the southwestern plateau. The wind turbines in these areas are severely affected by the climate, especially in the high-cold, high-altitude, and high-humidity environment. In winter, wind turbines are generally covered with ice due to freezing rain and condensation. Wind farms located in the high-cold mountainous areas of Yunnan, Guizhou, and Sichuan usually present the typical "three highs and one low" characteristics, high wind speed, high altitude, high humidity, and low temperature. During the winter icing period, the blades, nacelles, anemometers, cables and other components of wind turbines are at risk of freezing. Among them, as one of the key components of wind turbines, the icing problem of blades is particularly prominent. When the surface of the wind turbine blades is covered with ice, the aerodynamic efficiency of the blades is reduced, resulting in unstable power output of the wind turbine, resulting in serious loss of wind turbine power generation.

[0003] At present, the mainstream blade deicing technologies in the wind power industry include electric heating deicing technology, gas heating deicing technology and coating deicing technology. Among them, the deicing effects of gas heating deicing technology and coating deicing technology have been proven to be unsatisfactory through field tests. The gas heating deicing technology is mainly due to the oxygen resin conversion temperature characteristics of the blade wind turbine generator set. When the ambient temperature is lower than -5°C, the heating and temperature rise performance is extremely limited; and the coating deicing technology cannot play an effective deicing effect in high-altitude mountain wind farms due to the high-cold and high-humidity climate characteristics. For electric heating technology, it has been verified that this technology can achieve certain effects in high-cold mountain wind farms, but due to the characteristics of electric heating technology, it is easy to be struck by lightning when used in mountain wind farms, causing damage to the unit blades. Therefore, the blade deicing technology suitable for high-cold mountain wind farms has sufficient economic value and safety significance. Summary of the invention

[0016] A deicing method for a fan blade deicing device in a high-cold mountain area comprises the following steps:

[0017] S1. Data collection and preprocessing: The raw data collected by the monitoring module, including ambient temperature, humidity, wind speed, blade surface temperature, ice thickness, etc., are transmitted to the data processing module through the control module.

The fan blades can be lifted and heated by the heating module before they freeze, reducing the chance of icing on the fan blades.

[0024] 2. When de-icing the fan blades, the thickness of the ice on the fan blades and the changes in the external temperature are analyzed, and the pre-processed real-time data is input into the trained neural network.

When ice is difficult to remove from some parts of the fan blades, use the lifting mechanism to move the body to the vicinity of the ice, and use the ice-breaking blades and hot air flow to remove some of the ice. The hot air flow can melt the ice and reduce its binding force with the attached objects, while the mechanical force generated by the ice-breaking blades can directly impact and peel off the ice. The two work simultaneously and cooperate with each other to remove the ice faster. The gentle heating effect of the hot air flow combined with the relatively controllable mechanical force of the ice-breaking blades can reduce the potential damage to the fan blades caused by the strong impact of the ice-breaking blades. At the same time, the hot air flow can also prevent re-freezing.

[0037] A driving mechanism is installed between the lower end surface of the body 1 and the hollow shaft 7. The driving mechanism includes a vertical mounting plate 4, and the vertical mounting plate 4 is fixedly connected to the lower surface of the body 1. A motor 3 is installed on the side wall of the vertical mounting plate 4. The output end of the motor 3 is fixedly connected to a connecting assembly.

[0039] A deicing device for fan blades in high-cold mountainous areas, comprising a plurality of monitoring modules, a heating module, a vibration module, a control module and a data processing module, wherein the plurality of monitoring modules are evenly installed on the fan blades, and the monitoring module is composed of a temperature sensor, a humidity sensor, a wind speed sensor and an ice thickness sensor, and the temperature sensor, the humidity sensor, the wind speed sensor, the ice thickness sensor, the motor 3, the electric telescopic rod 12 and the air compressor 2 are all connected to the control module, and the data processing module is connected to the control module, and the vibration module and the heating module are both installed inside the fan blades, and the vibration module and the heating module are respectively connected to the control module;

[0040] The vibration module is mainly composed of a drive motor, an eccentric wheel, and a transmission shaft. The drive motor usually adopts a high-performance small motor to provide power for vibration generation; the eccentric wheel is installed on the output shaft of the drive motor. When the drive motor rotates, centrifugal force is generated due to the offset of the center of gravity of the eccentric wheel, thereby causing vibration; the transmission shaft connects the drive motor and the eccentric wheel to ensure the effective transmission of power;

[0041] The heating module is composed of high temperature resistant resistance wire or electromagnetic heating element, which is evenly distributed inside the fan blades and can quickly heat the blades according to the control instructions;

[0042] A deicing method for a fan blade deicing device in a high-cold mountain area comprises the following steps:

[0043] S1. Data collection and preprocessing: The raw data collected by the monitoring module, including ambient temperature, humidity, wind speed, blade surface temperature, ice thickness, etc., are transmitted to the data processing module through the control module. The data processing module first preprocesses these data to remove noise and outliers, and normalizes them to make them within a range suitable for neural network input;

[0044] S2, model training: using the collected data, the data processing module builds a neural network algorithm model for time series prediction, and trains the model through a large amount of historical data, so that it can accurately predict the formation trend and thickness change of the ice layer;

[0045] It is worth noting that the neural network algorithm model adopts a multi-layer feedforward neural network, including an input layer, multiple hidden layers and an output layer. The number of input layer nodes is determined according to the dimension of the collected data, the number of hidden layer nodes is determined through experiments and optimization, and the output layer nodes are used to output relevant instructions for de-icing control, such as heating time, heating power, vibration frequency and amplitude, etc.; a large amount of historical data is used for training, which covers different environmental conditions and icing conditions. During training, the back propagation algorithm is used to adjust the weights and biases of the network to minimize the error between the predicted value and the actual value. At the same time, regularization technology is used to prevent overfitting;

[0046] S3, de-icing decision: Based on the prediction results of the model, when it is predicted that the ice thickness is about to reach the threshold that affects the operation of the wind turbine, the de-icing operation is started. In actual operation, the pre-processed real-time data is input into the trained neural network, and the network quickly outputs the optimal parameters for de-icing control. For example, when the ice layer is thick and the ambient temperature is extremely low, the neural network may decide to use a longer heating time and a higher heating power, and at the same time, a larger amplitude of vibration;

[0047] S4, deicing method: Deicing is carried out by combining heating and mechanical vibration. According to the predicted ice layer conditions, the heating temperature and time, as well as the frequency and amplitude of mechanical vibration are accurately controlled to achieve efficient deicing and reduce damage to the blades;

[0048] S5. Real-time monitoring and adjustment: During the de-icing process, real-time data is continuously collected and input into the neural network algorithm model, the prediction results are updated in real time, and the parameters of the de-icing operation are adjusted according to the latest prediction results.

[0049] It is worth noting that when the ice on the fan blades is thicker and the heating module and vibration module inside the fan blades cannot quickly remove ice, the lifting mechanism is needed to drive the body 1 to move the part that needs to be de-iced, and then the motor 3 and the air compressor 2 are turned on through the control module. The motor 3 drives the connecting rod 5 connected thereto to rotate, and then drives the telescopic cylinder 11 and the telescopic shaft 17 to rotate. The first bevel gear 18 on the telescopic shaft 17 drives the second bevel gear 14 to rotate through gear meshing, thereby realizing the rotation of the hollow shaft 7. When the hollow shaft 7 rotates, it drives the ice-breaking blades 6 to rotate to cut the ice on the fan blades. At the same time, the air compressor 2 transmits compressed air through the rubber hose The gas is input to the vortex chamber inside the vortex tube 9, and the gas will form a high-speed rotating vortex. Due to the rotating motion of the gas, energy separation will occur inside the vortex tube 9. The air flow temperature near the center of the vortex tube 9 is relatively low, forming a cold air flow, which is discharged from the cold end tube, while the air flow temperature near the tube wall is relatively high, forming a hot air flow, which is discharged from the hot end tube. The hot air flow discharged from the hot end tube enters the annular hole 28 through the circular hole 27, the hollow shaft 7, the exhaust hole 25, the connecting hole 29 and the air inlet 31. The hot air flow entering the annular hole 28 is discharged from the ice-breaking blades 6 through multiple air outlets 19. The hot air flow contacts the ice cubes to accelerate the melting of the ice cubes, thereby reducing the difficulty of the ice-breaking blades 6 in cutting the ice cubes.

[0050] When it is necessary to adjust the feeding distance between the ice-breaking blades 6 and the ice cubes, the control module is used to open the electric telescopic rod 12, and the length of the electric telescopic rod 12 changes, thereby driving the movable plate 23 to move in the movable groove 16, and the distance between the fixed mounting frame 15 and the L-shaped mounting frame 13 changes. The telescopic shaft 17 drives the sliding card strip 20 thereon to move in the sliding card slot 21, thereby realizing the change of the distance between the ice-breaking blades 6 and the machine body 1. The feeding distance between the actual ice-breaking blades 6 and the ice cubes can be adjusted without changing the overall position of the machine body 1. Since the distance adjustment unit of the overall position of the machine body 1 is large, it is avoided to adjust the feeding distance between the ice-breaking blades 6 and the ice cubes by adjusting the overall position of the machine body 1, and to avoid collision between the machine body 1 and the fan blades caused by improper operation.

[0051] The above description is only a preferred specific implementation manner of the present invention, but 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 scheme and inventive concept 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.
