Its embedded design can adapt to harsh outdoor or industrial operating conditions of wind turbines, avoiding the problems of interference and collisions that external sensors are susceptible to, and helping to reduce operation and maintenance costs.

[0003] The existing wind turbines have embedded multi-source data acquisition sensors that lack time detection, wind speed detection, and smoke detection alarm functions. This results in the lack of accurate timestamps in the collected data, making it impossible to trace the temporal relationship of changes in different parameters. Furthermore, the wind turbines cannot be dynamically adjusted to adapt to wind speed, and they cannot detect potential smoke hazards around the wind turbines in a timely manner, creating a safety warning blind spot.

Detailed Implementation

[0020] As core equipment for energy conversion and fluid transport, wind turbines are widely used in wind power generation, industrial production (chemical, metallurgical, building materials), and building ventilation. Their long-term stable operation directly determines energy utilization efficiency and production safety. Taking onshore wind turbines as an example, the cost of a single unit is high, and a one-day shutdown due to component failure can result in considerable economic losses. In the industrial sector, if bearing wear of high-pressure wind turbines is not detected in time, it may cause sudden equipment shutdown, leading to production line stoppage and even more serious losses. Against this backdrop, real-time monitoring of wind turbine operating status has become an urgent need for the industry. Traditional monitoring methods rely on manual inspections, with maintenance personnel using handheld devices to detect parameters such as vibration and temperature. This is not only inefficient (inspecting a single wind turbine can take several hours) but also has "monitoring blind spots." For example, core components such as gearboxes and motor windings inside the nacelle are difficult to access frequently, and manually recorded data lacks continuity, making it impossible to capture instantaneous fault signals. With the continuous advancement of intelligent transformation, "online real-time monitoring" has gradually become the mainstream direction. As the "sensing core" of the monitoring system, the performance of data acquisition and sensing devices directly determines the monitoring effect. This has also driven the upgrading of related technologies from "external" to "embedded" and from "single parameter acquisition" to "multi-source data fusion".

[0021] The core technology system of the device is built around multi-dimensional needs: In terms of multi-source sensors, piezoelectric vibration sensors can capture abnormal vibrations in bearings and gearboxes, covering the common vibration intensity and frequency ranges of fans; PT100 platinum resistance temperature sensors can monitor temperature changes in motor windings and bearing housings, adapting to the temperature range during fan operation and with high measurement accuracy; the combination of "blade-rotor-magnetic speed detector" can realize wind speed acquisition, covering the common wind speed range required for fan operation; photoelectric smoke sensors have high sensitivity to smoke and can provide timely warnings of fires; Hall current sensors and photoelectric speed sensors are used to monitor motor operating parameters. All sensors are miniaturized and integrated to avoid occupying too much space inside the fan.

[0022] The data preprocessing module processes the raw data using a variety of algorithms: notch filtering can remove common power frequency interference, wavelet filtering can extract high-frequency signals related to faults, and moving average filtering can smooth the drift trend of temperature data. At the same time, a timer periodically sends a synchronization signal to add a precise timestamp to all data, solves the problem of timing deviation, and ensures that the data has a high accuracy.

[0023] The embedded installation and protection design uses a base plate as the basic carrier: the front end of the device is fixed through a "front mounting plate + threaded holes", and mounting blocks and mounting ports are set on both sides to form a multi-directional fixing structure of "front end + both sides" to improve installation stability; the hollow groove at the bottom of the base plate can reduce the overall weight of the device and enhance heat dissipation; the shell adopts an ABS+PC alloy integrated injection molding process, which has good dust and water resistance and is suitable for onshore wind turbine scenarios. If used for offshore wind turbines, the surface of the shell will be sprayed with a special coating to improve salt spray resistance and further enhance the protection effect; the internal epoxy resin potting can improve vibration resistance and moisture resistance, and the interface adopts waterproof aviation plugs to prevent loosening. The overall design can adapt to the harsh outdoor and industrial working conditions of wind turbines.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides an embodiment: a multi-source data acquisition and sensing device is embedded in a fan, including a base plate 1 and a support block 21 installed on the rear top of the base plate 1. A speed detector 22 is connected to the top of the support block 21, a timer 23 is connected to the left end of the speed detector 22, and a data cable 24 is connected to the rear end of the speed detector 22. The end of the data cable 24 away from the speed detector 22 is connected to the support block 21. An interface 25 is connected to the left end of the support block 21 and is connected to the data cable 24. A rotating drum 26 is rotatably connected to the front end of the speed detector 22. Multiple blades 27 are connected to the outer end of the rotating drum 26. A fixed cylinder 28 is rotatably connected inside the rotating drum 26. A smoke sensor 29 is connected inside the fixed cylinder 28. A connecting wire 210 is connected to the bottom of the smoke sensor 29 through the fixed cylinder 28 and is connected to the interface 25. Airflow passes through the blades 27, causing the rotating drum 26 to rotate on the fixed cylinder 28. The speed detector 22 is used to detect the speed of the rotating drum 26, and the timer 23 is automatically counted when powered on. At the same time, the smoke sensor 29 is used to detect smoke. By setting the timer 23, blades 27, rotating drum 26, and smoke sensor 29, the timer 23 automatically starts timing after being powered on, which can add accurate timestamps to the collected data, solving the problem that the original device could not trace the timing relationship of parameter changes, and helping to accurately associate the logic of different parameter changes in the future. The airflow drives the blades 27 to make the rotating drum 26 rotate on the fixed drum 28. The speed detector 22 detects the speed of the rotating drum 26. The wind speed can be detected by the correlation between the speed and the wind speed, solving the problem that the original device could not dynamically adjust the adaptability of the fan operation according to the wind speed, making the fan operation more in line with the real-time environment. The smoke sensor 29 is connected to the interface 25 through the connecting cable 210, which can detect the smoke around the fan in real time, solving the problem that the original device could not detect the smoke hazard in time, eliminating the blind spot of safety warning, and improving the safety of fan operation. At the same time, the connection of the data cable 24, the interface 25 and the various components ensures the stable transmission of time data, speed data and smoke data, ensuring that the function is effectively implemented.

[0026] Please see Figure 2-5 A further solution based on this embodiment is as follows: a baffle 31 is connected to the front end of the base plate 1, and the baffle 31 is connected to the fixed cylinder 28. The front end of the baffle 31 is provided with multiple air inlets 32. The baffle 31 can block dust, debris and other impurities in the fan operating environment from entering the device, and prevent impurities from adhering to the rotating cylinder 26, blades 27 or sensor surface and affecting the detection accuracy. The multiple air inlets 32 can guide the airflow to flow stably and evenly to the rotating cylinder 26 and blades 27, ensuring that the wind speed correlation data collected by the speed detector 22 is more accurate, while balancing the airflow pressure inside the device and reducing the interference of airflow turbulence on the operation of the components.

[0027] Please see Figure 1-5A further solution based on this embodiment is as follows: a front mounting plate 33 is connected to the bottom front side of the base plate 1. Threaded holes 34 are opened on the left and right sides of the front end of the front mounting plate 33. The front mounting plate 33 provides a dedicated mounting carrier for the front end of the device. The threaded holes 34 on the left and right sides can be adapted to external fasteners of different specifications, so as to conveniently fix the front end of the device in a designated position inside the fan, solve the problem of no force point and unstable fixation in traditional installation, and improve the positional stability of the device after installation.

[0028] Please see Figure 1-5 A further solution based on this embodiment is as follows: the threaded hole 34 is threadedly connected to the external screw, and two mounting blocks 35 are respectively connected to the left and right ends of the base plate 1. The cooperation between the threaded hole 34 and the external screw enables the front mounting plate 33 to be detachably fixed, which facilitates the later maintenance or position adjustment of the device. The mounting blocks 35 at the left and right ends of the base plate 1 increase the lateral mounting points of the device, forming a multi-directional fixing structure of "front end + both sides" with the front mounting plate 33, which greatly enhances the overall installation stability of the device and avoids the device from shifting due to the vibration of the fan operation.

[0029] Please see Figure 1-5 A further solution based on this embodiment is as follows: the mounting block 35 has an internal mounting port 36, and the internal part of the mounting port 36 is threadedly connected to the external screw. The mounting port 36 provides a flexible fixing and adaptation space for the mounting block 35, which can be compatible with external screws of different lengths and diameters, and can be adapted to mounting brackets or fixing surfaces of different thicknesses inside the fan. The threaded connection between the screw and the mounting port 36 ensures that the mounting block 35 is firmly fixed, further strengthening the lateral support of the device, while reducing the adaptation threshold to the installation environment.

[0030] Please see Figure 1-5 A further solution based on this embodiment is as follows: a hollow groove 37 is provided at the bottom of the base plate 1, and a Bluetooth module 38 is connected to the rear end of the support block 21. The hollow groove 37 can reduce the overall weight of the device, reduce the load on the internal mounting carrier of the fan, and at the same time enhance the heat dissipation performance of the base plate 1, avoiding the accumulation of heat generated by the long-term operation of the internal components of the device; the Bluetooth module 38 adds a wireless data transmission channel to the device, getting rid of the limitation of the traditional data cable 24 on the installation position, and facilitating the remote reception of data such as speed and time.

[0031] Please see Figure 1-5A further solution based on this embodiment is as follows: Bluetooth module 38 is electrically connected to speed detector 22 and timer 23, Bluetooth module 38 is electrically connected to interface 25, and Bluetooth module 38 is electrically connected to speed detector 22 and timer 23. The electrical connection between Bluetooth module 38 and speed detector 22 and timer 23 enables real-time wireless transmission of wind speed-related speed data and timestamped data, ensuring the timeliness of data transmission; the electrical connection with interface 25 enables bidirectional compatibility between Bluetooth transmission and wired transmission. When wired transmission fails, Bluetooth module 38 can serve as a backup transmission method to ensure uninterrupted data transmission and improve the reliability of data transmission in the device.

[0032] Working Principle: First, stable fixation is achieved through the installation structure. The threaded holes 34 on the left and right sides of the front mounting plate 33 and the mounting openings 36 inside the mounting blocks 35 at both ends of the base plate 1 are connected to external screws, forming a multi-directional fixation of "front end + both sides." This ensures the device is securely installed inside the fan, preventing displacement due to fan vibration. After the device is fixed, the airflow generated during fan operation first contacts the baffle 31. The airflow flows stably and evenly through multiple air inlets 32 at the front of the baffle 31 to the blades 27 at the outer end of the rotating drum 26, causing the rotating drum 26 to rotate on the fixed cylinder 28. Then, the data acquisition stage begins. The speed detector 22 detects the rotation speed of the rotating drum 26 in real time (obtaining wind speed data through speed correlation conversion), and the timer 23 is simultaneously powered on and automatically timestamps the rotation speed and subsequent smoke detection data. Meanwhile, the internal components of the fixed cylinder 28... The smoke sensor 29 continuously monitors the smoke status around the fan, capturing potential smoke hazards. After data acquisition, it enters the transmission stage. Rotation speed data, timestamped information, and smoke detection data are transmitted via data cable 24 to interface 25 on the left end of support block 21, and then transmitted outward from interface 25. At the same time, Bluetooth module 38, which is electrically connected to rotation speed detector 22, timer 23, and interface 25, synchronously realizes the wireless transmission of these data. When data cable 24 fails, Bluetooth module 38 can serve as a backup transmission method to ensure uninterrupted data transmission. Throughout the entire operation, the hollow groove 37 at the bottom of base plate 1 reduces the overall weight of the device and the load-bearing burden on the internal mounting carrier of the fan. On the other hand, it enhances the heat dissipation performance of base plate 1, preventing the accumulation of heat generated by components such as rotation speed detector 22 and timer 23 during long-term operation, and ensuring the continuous and stable operation of the device.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
