[0002] Wind turbine blades need to be heated and cured during the molding process. Specifically, the mold heating system and the blade root heat circulation fan are used to make the adhesive reach a set temperature and maintain it for a period of time to complete the curing of the blade.

In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] Wind turbine blades need to be heated and cured during the molding process. Specifically, the mold heating system and the blade root heat circulation fan are used to make the adhesive reach a set temperature and maintain it for a period of time to complete the curing of the blade.

[0046] Regarding the temperature control of the curing process, in the related art, the mold heating system uses the feedback value of the temperature probe embedded in the mold and the heating controller to perform closed-loop control of the curing temperature, and the hot air blower uses the feedback value of the temperature probe in the air duct and the heating rod to perform closed-loop control of the curing temperature. During heating and curing, the temperature of the mold heating system often needs to be set to 85-90°C. Through heat transfer, the temperature of the mold cavity reaches 70°C to heat and cure the blades in the cavity. However, the temperature of the mold cavity rises slowly, about 1.5 hours slower than the temperature of the mold itself, resulting in a slower temperature rise of the blades in the cavity. Therefore, the temperature measured by the temperature probe in the mold heating system and the hot air blower is not the actual temperature of the blade. The solution of the related art has the problem of inaccurate temperature control.

[0047] In order to solve the above technical problems, the embodiments of the present application provide a temperature control method, system, equipment, medium and product for curing wind turbine blades, which can achieve more accurate temperature control of the curing process of wind turbine blades.

[0048] Figure 1 A schematic flow chart of a temperature control method for curing a wind turbine blade provided in an embodiment of the present application;

[0049] Next, combine Figure 1 A temperature control method for curing a wind turbine blade according to an embodiment of the present application is introduced. Corresponding temperature sensors are respectively provided at multiple detection points on the blade. The method comprises the following steps:

[0050] S110, in the process of heating the blade by using the mold heating system and the heat circulation fan, obtaining multiple temperatures corresponding to multiple temperature sensors on the blade in real time;

[0051] S120, determining a target temperature according to a plurality of temperatures;

[0052] S130, when the target temperature reaches the first preset temperature, performing curing and heat preservation, and recording the curing and heat preservation time;

[0053] S140, during the curing and heat preservation process, adjusting the power of the mold heating system and the heat circulation fan and the air volume of the heat circulation fan so that the target temperature is within a preset temperature range, the preset temperature range includes a temperature interval consisting of a first temperature and a second temperature, the first temperature is the first preset temperature minus a temperature deviation, and the second temperature is the first preset temperature plus the temperature deviation;

[0054] S150, when the curing and heat preservation time reaches the preset time, the mold heating system and the heat circulation fan are turned off.

[0055] According to the temperature control method for curing of wind turbine blades provided in the embodiment of the present application, since corresponding temperature sensors are respectively provided at multiple detection points on the blades, a more real and accurate temperature of the blades can be measured. In the process of heating the blades by using the mold heating system and the heat circulation fan, multiple temperatures corresponding to the multiple temperature sensors on the blades are obtained in real time, and the target temperature is determined according to the multiple temperatures. When the target temperature reaches a first preset temperature, curing and heat preservation are performed, and the curing and heat preservation time is recorded. During the curing and heat preservation process, the power of the mold heating system and the heat circulation fan and the air volume of the heat circulation fan are adjusted so that the target temperature is within a preset temperature range. The preset temperature range includes a temperature interval consisting of a first temperature and a second temperature. The first temperature is the first preset temperature minus the temperature deviation, and the second temperature is the first preset temperature plus the temperature deviation. When the curing and heat preservation time reaches the preset duration, the mold heating system and the heat circulation fan are turned off, so that more precise temperature control of the curing of the wind turbine blades can be achieved.

[0056] Regarding the above S110, according to the process requirements, before the post-curing begins, multiple detection points can be set corresponding to multiple areas such as the 0.5-meter mold seam inside the root of the blade, the starting point of the web bonding, and the mold splicing seam. A temperature sensor is set at each detection point, and various forms of temperature sensors such as thermocouples, thermistors, infrared temperature measurement, and 18B20 sensors can be used.

[0057] After the mold heating and heat circulation fan are turned on, the heating process begins, and the mold temperature and the temperature inside the cavity rise successively. During the heating process, multiple temperatures corresponding to multiple temperature sensors on the blades are obtained in real time.

[0058] The mold heating system can be electric heating, water heating or other forms of heating systems.

[0059] Regarding the above S120, a target temperature is determined based on multiple temperatures, and the target temperature is the cavity control temperature. Subsequently, heating and curing and heat preservation are controlled based on the temperature, wherein the target temperature can be an average temperature calculated based on multiple temperatures.

[0060] In some embodiments of the present application, the target temperature may also be the lowest temperature among multiple temperatures. The above S120 includes:

[0061] The lowest temperature among the plurality of temperatures is determined as the target temperature.

[0062] Regarding the above S130, when the target temperature reaches the first preset temperature, curing and heat preservation are performed, and the curing and heat preservation time is recorded. The first preset temperature is the curing temperature, for example, it can be 70°C. Of course, the first preset temperature can also be other values, and the specific value can be set according to the process requirements.

[0063] Regarding the above S140, the preset temperature range includes a temperature interval consisting of a first temperature and a second temperature, the first temperature is the first preset temperature minus the temperature deviation, and the second temperature is the first preset temperature plus the temperature deviation. For example, the preset temperature range is T 0 ±ΔT=72±2°C, then the first temperature is 70°C and the second temperature is 74°C.

[0064] During the curing and heat preservation process, the power of the mold heating system and the heat circulation fan and the air volume of the heat circulation fan are adjusted to ensure that the target temperature is within the preset temperature range.

[0065] Regarding the above S150, when the curing and heat preservation time reaches the preset time, the mold heating system and the heat circulation fan are turned off, and the curing process of the blade is completed. The preset time can be, for example, 4 hours, and of course the preset time can also be other values, and the specific value can be set according to the process requirements.

[0066] In some embodiments of the present application, the temperature control method for curing a wind turbine blade further includes:

[0067] The loop does the following:

[0068] In the process of heating the blades by using the mold heating system and the heat circulation fan, the mold temperature inside the mold is obtained in real time;

[0069] When the mold temperature is greater than the second preset temperature and the target temperature is less than the first preset temperature, the heating of the blades is suspended until the mold temperature is less than the second preset temperature, and then the heating of the blades is restarted.

[0070] Specifically, the mold temperature can be determined by the feedback value of a temperature measuring probe pre-buried in the mold.

[0071] The second preset temperature may be T max =95℃, which is the upper limit of the mold temperature. Of course, the second preset temperature can also be other values. The specific value can be set according to the process requirements. When the mold temperature in the mold reaches the upper limit of the mold temperature and the blade has not reached the curing temperature, continuing to heat it may cause quality defects of the blade. Therefore, suspending the heating of the blade first and reheating the blade after the mold temperature drops can avoid quality defects caused by overheating.

[0072] Figure 2 A schematic flow chart of another temperature control method for curing wind turbine blades provided in an embodiment of the present application;

[0073] Combination Figure 2 In some embodiments of the present application, adjusting the power of the mold heating system and the heat circulation fan and the air volume of the heat circulation fan so that the target temperature is within a preset temperature range includes the following steps:

[0074] S210, when the target temperature is higher than the second temperature, reducing the power of the mold heating system and the heat circulation fan and reducing the air volume of the heat circulation fan so that the target temperature is within a preset temperature range;

[0075] S220, when the target temperature is lower than the first temperature, increasing the power of the mold heating system and the heat circulation fan and increasing the air volume of the heat circulation fan so that the target temperature is within a preset temperature range.

[0076] Specifically, the actual temperatures of multiple wireless temperature probes can be used as feedback values, and the lowest temperature among them can be compared with the set value to form a PID closed-loop control. The control system uses a PID (proportional-integral-differential) controller, which can adjust the heating power output and air volume of the hot air blower according to the difference between the set temperature and the actual temperature. To avoid temperature fluctuations, the upper and lower limits of temperature and air volume adjustment are set, that is, the heating and air volume output are within the upper and lower limits when the system automatically adjusts.

[0077] The mold heating adds a master control function. The system receives data from the wireless temperature measurement points in the cavity and compares it with the set post-curing temperature. Due to the large total power of the mold heating system, the heat is slowly transferred to the inside of the cavity through the heating tube in the mold shell. When heating, set the upper and lower limits of the temperature. The upper limit is higher than a certain range of the post-curing temperature, such as 5°C, and the lower limit is slightly higher than the set post-curing temperature. When the set post-curing temperature is reached, the plan starts, and the heating is disconnected when the temperature reaches the upper limit to avoid a large deviation between the actual temperature and the process requirements. When the temperature drops and reaches near the set temperature, continue to turn on the heating to avoid the mold heating system starting too late and the temperature in the cavity is lower than the set post-curing temperature. When the temperature is between the two, keep heating and maintain temperature stability through its own heating control system. The system automatically records and counts the time it takes to reach the post-curing temperature, and automatically stops heating after the set time. The master control function can be canceled or enabled through the administrator interface.

[0078] For the heat circulation fan, the heat and heating power delivered to the cavity through the air duct are positively correlated with the air supply volume. According to the target temperature obtained by feedback, the controller dynamically adjusts the fan speed through the inverter to change the air supply volume; at the same time, adjusts the proportion of the heating rod power on time per unit time, that is, when the temperature is low, the power on time is increased, and when the temperature is high, the power on time is reduced. The specific adjustment ratio is calculated by the control program inside the controller.

[0079] In this way, according to the above power regulation method, the cavity temperature can be maintained near the set curing temperature to complete the curing of the blade.

[0080] Figure 3 A schematic flow chart of another temperature control method for curing a wind turbine blade provided in an embodiment of the present application;

[0081] Combination Figure 3 In some embodiments of the present application, the temperature control method for curing a wind turbine blade further includes the following steps:

[0082] S310, in the process of heating and curing, for each of the plurality of detection points, obtaining in real time a plurality of third temperatures measured by a temperature sensor;

[0083] S320, calculating an average temperature according to a plurality of third temperatures;

[0084] S330, calculating the difference between the average temperature of the target detection point and the average temperature of other detection points, where the target detection point is any one of the multiple detection points, and the other detection points are detection points other than the target detection point among the multiple detection points;

[0085] S340, when the difference is greater than the preset difference, output the first alarm information, exclude the target detection point, use the remaining detection points as multiple detection points, and return to execute in the process of heating the blade using the mold heating system and the heat circulation fan, and obtain multiple temperatures corresponding to the multiple temperature sensors on the blade in real time.

[0086] The preset difference may be 5°C. Of course, the preset difference may also be other values. The specific value may be set according to the process requirements.

[0087] When the difference between the average temperature of the target detection point and the average temperature of other detection points exceeds 5°C, it means that the temperature sensor corresponding to the target detection point has failed. At this time, the temperature sensor cannot measure the actual temperature of the detection point. Therefore, the detection point is excluded, and subsequent temperature control no longer refers to this detection point. Using the remaining detection points for temperature control can avoid the problem of inaccurate temperature control.

[0088] The first alarm information is used to remind the staff that the temperature of the target detection point is abnormal, so as to remind the staff to deal with it in time.

[0089] In some embodiments of the present application, the temperature control method for curing a wind turbine blade further includes:

[0090] When the target temperature exceeds the preset temperature range, a second alarm message is output.

[0091] The second alarm message is used to remind the staff that the insulation process is abnormal, so as to remind the staff to deal with it in time.

[0092] In some embodiments of the present application, the temperature control method for curing a wind turbine blade further includes:

[0093] When the curing and heat preservation time reaches the preset time, the third alarm information is output.

[0094] The third alarm message is used to remind the staff that the curing and heat preservation is completed, so as to remind the staff to turn off the mold heating system and the heat circulation fan in time.

[0095] In some embodiments of the present application, the temperature control method for curing a wind turbine blade further includes:

[0096] In the event of a failure of the mold heating system and the heat circulation fan, a fourth alarm message is output.

[0097] The fourth alarm information is used to inform the staff that the equipment fails, so as to remind the staff to shut down the equipment in time and repair the equipment.

[0098] The embodiment of the present application provides a temperature control system for curing a wind turbine blade, the system comprising:

[0099] A plurality of temperature sensors, the plurality of temperature sensors are respectively arranged at a plurality of detection points of the blade, and the plurality of temperature sensors are used to measure the temperature of the plurality of detection points of the blade;

[0100] The mold heating system and heat circulation fan are used to heat the blades and to cure and keep them warm;

[0101] In the process of heating, curing and heat-insulating the blades, any one of the above-mentioned temperature control methods for curing wind turbine blades is used to control the temperature.

[0102] According to the temperature control system for curing of wind turbine blades provided in the embodiment of the present application, since corresponding temperature sensors are respectively provided at multiple detection points on the blades, a more real and accurate temperature of the blades can be measured. In the process of heating the blades by using the mold heating system and the heat circulation fan, multiple temperatures corresponding to the multiple temperature sensors on the blades are obtained in real time, and the target temperature is determined according to the multiple temperatures. When the target temperature reaches a first preset temperature, curing and heat preservation are performed, and the curing and heat preservation time is recorded. During the curing and heat preservation process, the power of the mold heating system and the heat circulation fan and the air volume of the heat circulation fan are adjusted so that the target temperature is within a preset temperature range. The preset temperature range includes a temperature interval consisting of a first temperature and a second temperature. The first temperature is the first preset temperature minus the temperature deviation, and the second temperature is the first preset temperature plus the temperature deviation. When the curing and heat preservation time reaches the preset duration, the mold heating system and the heat circulation fan are turned off, so that more precise temperature control of the curing process of the wind turbine blades can be achieved.

[0103] In the embodiment of the present application, a temperature sensor is used to detect the actual temperature of multiple points inside the cavity, and the slowest heating point that meets the curing requirements is determined, which is used for temperature feedback of heating control;

[0104] During the heating process, the high temperature points are warned and the heating system is linked for adjustment;

[0105] Real-time recording and regular push of actual temperature and warning information to staff;

[0106] The mold and hot air blower use the temperature feedback inside the cavity to adjust the heating power in real time, forming a closed-loop control to keep the actual internal temperature near the required curing temperature.

[0107] Set the upper limit of mold temperature and stop heating when it exceeds the upper limit to avoid overheating of mold and affecting product quality;

[0108] During the heating process, the curing temperature, curing insulation time and other parameters are preset; the heater start-up time, the time when the internal temperature reaches the specified temperature (generally 70°C) are automatically recorded, and the machine automatically stops after the curing insulation time is reached.
