Description

Technical Field

[0001] This invention relates to the field of electrical equipment monitoring technology, and in particular to an electrical equipment operation safety monitoring mechanism. Background Technology

[0002] Wind power generation equipment, as a clean energy technology that uses natural wind power to drive generators and produce electricity, is increasingly being used globally. In large electrical equipment such as wind turbine generators, the hub-to-shaft connection, as the core component for power transmission, is subjected to complex alternating loads and extreme environmental impacts over long periods, making it prone to structural defects such as loose bolts, weld fatigue, and shaft misalignment. Traditional monitoring methods typically use fixed sensors, which have limited monitoring range and cannot comprehensively capture abnormal conditions distributed circumferentially at the connection.

[0003] Especially during transient start-stop and pitch control processes, stress concentration and sudden vibration changes often exhibit directional characteristics. Fixed monitoring systems are prone to creating data blind spots, leading to delayed early fault identification and impacting the efficiency of equipment safety operation and maintenance decisions. Existing monitoring solutions often statically deploy sensors on the nacelle walls or near bearing housings, making it difficult to adapt to the three-dimensional dynamic characteristics of the hub and main shaft connection. Furthermore, the confined space and strong electromagnetic interference within the nacelle pose challenges to sensor positioning accuracy and data transmission reliability. Summary of the Invention

Detailed Implementation

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] Example 1: This example provides an operational safety monitoring mechanism for electrical equipment. See [link to example]. Figures 1 to 6 Specifically, it includes a base 100, a tower body 101 fixedly installed on the top surface of the base 100, a nacelle 102 rotatably installed on the top of the tower body 101, a hub 103 rotatably installed at the front end of the nacelle 102, the inner end of the hub 103 extending into the nacelle 102 and connected to the main shaft inside the nacelle 102, and three evenly distributed wind blades 104 rotatably installed on the outer ring surface of the hub 103.

[0045] The left side wall inside the engine compartment 102 is provided with a pair of symmetrically distributed arc-shaped slide rails 200. A pair of connecting plates 201 are fixed at both ends of the arc-shaped slide rails 200. The inner end of each connecting plate 201 is fixed to the left side wall inside the engine compartment 102. A U-shaped sliding plate 202 is slidably fitted on each arc-shaped slide rail 200. A pair of monitoring sensor modules 105 are fixedly installed on the opposite surfaces of the pair of U-shaped sliding plates 202. The pair of monitoring sensor modules 105 are used to monitor the connection between the hub 103 and the main shaft inside the engine compartment 102. A data processing module 106, a background monitoring module 107, and a power supply module 108 are installed side by side on the left side wall inside the engine compartment 102.

[0046] Two pairs of symmetrically distributed U-shaped rails 208 are fixedly installed on the left side wall inside the cabin 102. A U-shaped bracket 210 is slidably fitted between each pair of U-shaped rails 208. A pair of T-shaped sliders are fixed at both ends of the U-shaped bracket 210. The outer end of each T-shaped slider is slidably engaged in the corresponding U-shaped rail 208. A linkage belt 207 for driving the U-shaped bracket 210 to slide back and forth is installed between each pair of U-shaped rails 208. Each U-shaped bracket 210 is connected to the corresponding U-shaped slide plate 202 on one side through a limiting component.

[0047] The working principle of this embodiment is as follows: the U-shaped slide plate 202 is driven to slide back and forth along the arc-shaped slide rail 200 by the limiting component, and the monitoring sensor module 105 on the U-shaped slide plate 202 is driven to move back and forth along the arc-shaped trajectory around the connection between the hub 103 and the main shaft inside the cabin 102.

[0048] Vibration, stress, and temperature data at the connection point between the hub 103 and the main shaft inside the engine compartment 102 are collected by a pair of monitoring sensor modules 105 and transmitted in real time to the data processing module 106 via a wireless RF module.

[0049] The U-shaped slide plate 202 is driven to slide back and forth along the arc-shaped slide rail 200 by the limiting component, which simultaneously drives the monitoring sensor module 105 installed on the U-shaped slide plate 202 to move back and forth along the arc trajectory around the connection between the hub 103 and the main shaft inside the cabin 102.

[0050] Vibration, stress and temperature data at the connection between the hub 103 and the main shaft inside the engine compartment 102 are collected by a pair of monitoring sensor modules 105, and the data are transmitted to the data processing module 106 in real time with the help of a wireless RF module.

[0051] The data processing module 106's acquisition unit synchronously receives data from a pair of monitoring sensor modules 105, and the data preprocessing unit performs filtering and standardization to remove noise interference.

[0052] The pre-processed data in a unified format is transmitted to the background monitoring module 107 via 4G / 5G or Ethernet, and the storage unit completes data archiving.

[0053] The background real-time monitoring unit dynamically displays the monitoring parameters of a pair of monitoring sensor modules 105, and the fault early warning unit continuously compares the data with the preset threshold.

[0054] When a monitoring sensor module 105 detects that a parameter exceeds the threshold, the system immediately triggers a graded early warning, clearly marking the location of the abnormal sensor and the corresponding fault type.

[0055] Maintenance personnel can view real-time data and historical trends through the back-end interface, formulate maintenance plans based on early warning information, and the system records the entire fault handling process and updates equipment health records.

[0056] Example 2: Based on Example 1, this example solves the key problem of how to accurately control the monitoring sensor module 105 to reciprocate along a complex arc trajectory by using a precision positioning transmission mechanism driven by motor 205. It also includes:

[0057] In the specific implementation process, such as Figure 4 and Figure 5 As shown, a fixed ear seat is fixedly provided on the outer surface of the linkage belt 207, and a limiting pin 209 is fixedly inserted into the outer end of the fixed ear seat. An elliptical pin hole 211 is opened in the middle of the U-shaped bracket 210, and the outer end of the limiting pin 209 is slidably engaged in the corresponding elliptical pin hole 211.

[0058] A pair of motors 205 are fixedly installed on the left side wall inside the cabin 102, and a pair of driven shafts 206 are rotatably installed on the left side wall inside the cabin 102. Each pair of U-shaped rails 208 has a motor 205 and a driven shaft 206 distributed between the two ends.

[0059] The output end of the motor 205 is fixedly fitted with a drive pulley, the outer end of the driven shaft 206 is fixedly fitted with a driven pulley, and the two ends of the linkage belt 207 are respectively fitted on the corresponding drive pulley and driven pulley;

[0060] The limiting assembly includes a hinged swing arm 203 and an L-shaped slide plate 212. The hinged swing arm 203 is hinged on the U-shaped slide plate 202. A rectangular sleeve 204 is fixed to the outer end of the hinged swing arm 203. The L-shaped slide plate 212 is fixed to the middle of the U-shaped bracket 210. The outer end of the L-shaped slide plate 212 is slidably inserted into the rectangular sleeve 204.

[0061] The working principle of this embodiment is as follows: Under the drive of the motor 205, the active pulley rotates accordingly, and the driven pulley rotates synchronously through the linkage belt 207; the limiting pin 209 fixed on the linkage belt 207, through the sliding cooperation with the elliptical pin hole 211 on the U-shaped bracket 210, converts the belt rotation motion into the precise reciprocating linear motion of the U-shaped bracket 210 along the U-shaped rail 208;

[0062] Subsequently, the U-shaped bracket 210 drives the L-shaped slide plate 212 on it to move synchronously. The outer end of the L-shaped slide plate 212 is slidably inserted into the rectangular sleeve 204 of the hinged swing arm 203. This sliding pair constrains the linear motion of the U-shaped bracket 210 and converts it into the swing of the hinged swing arm 203, thereby driving the U-shaped slide plate 202 to slide stably back and forth along the arc-shaped slide rail 200.

[0063] Ultimately, the U-shaped sliding plate 202 drives the monitoring sensor module 105 on it to precisely complete the scanning and monitoring task along a preset arc trajectory around the connection between the hub 103 and the main shaft inside the cabin 102.

[0064] Example 3: Based on Example 2, this example solves the technical challenge of comprehensive status perception and accurate fault diagnosis at the connection between the wheel hub 103 and the main shaft by using a complete monitoring system integrating high-precision sensing, real-time data processing, and intelligent early warning. It also includes:

[0065] In the specific implementation process, such as Figure 6 As shown, the monitoring sensor module 105 integrates a vibration detection unit, a stress detection unit, a temperature compensation unit, and a data transmission unit, wherein:

It is used to collect vibration signals at the connection between the hub 103 and the main shaft inside the engine compartment 102, and to capture vibration anomalies caused by imbalance.

[0068] Temperature compensation unit: Built-in digital temperature sensor, measuring range -40~+80℃, accuracy ±0.3℃, used to collect the ambient temperature at the connection between the hub 103 and the main shaft inside the engine compartment 102, to compensate for temperature drift of vibration and stress signals, and improve data accuracy;

[0069] Data transmission unit: integrates a wireless radio frequency (RF) module, with a communication frequency band of 433MHz, a transmission distance of ≥2km, a communication rate of ≥38.4kbps, and supports real-time data interaction with the data processing module 106.

[0070] The data processing module 106 serves as the intermediate hub between the monitoring sensor module 105 and the background monitoring module 107, responsible for data acquisition, integration, preprocessing, and transmission. It includes a data acquisition unit, a data preprocessing unit, and a data transmission unit, wherein:

[0071] Data acquisition unit: Built-in dual-channel data acquisition chip, sampling rate synchronized with monitoring sensor module 105 (50~500Hz), supports parallel reception of raw data from a pair of monitoring sensor modules 105, acquisition delay ≤10ms, ensuring data synchronization;

[0072] Data preprocessing unit: Equipped with a low-power microcontroller (MCU), it runs a moving average filtering algorithm and a data standardization processing program to filter out environmental interference noise and convert vibration, stress, and temperature data into digital signals in a unified format (JSON format).

[0073] Data transmission unit: Supports wired (Ethernet) and wireless (4G / 5G) dual-mode transmission, adopts wireless transmission, and automatically switches to wired transmission when the signal is interrupted; the transmission protocol adopts TCP / IP to ensure the stability and security of data transmission, with a data packet loss rate of ≤0.1%.

[0074] The backend monitoring module 107 is deployed in the remote monitoring center and includes a data storage unit, a real-time monitoring unit, a fault early warning unit, and a historical tracing unit to achieve full-process data management.

[0075] Data storage unit: It adopts a distributed database with a storage capacity of ≥500GB, supports the storage of historical data (including raw data and preprocessed data) of a pair of monitoring sensor modules 105, and has a storage period of ≥3 years, which is convenient for subsequent traceability and analysis;

[0076] Real-time monitoring unit: Equipped with a visual monitoring interface, it displays the core parameters of vibration effective value, stress peak value, and ambient temperature collected by a pair of monitoring sensor modules 105 in real time, dynamically updates the data curve, and has a data refresh frequency of ≤1s, intuitively presenting the operating status of the connection point;

[0077] Fault warning unit: presets multi-dimensional fault judgment thresholds, identifies abnormal states by comparing real-time data with the thresholds; warning methods include interface pop-up, audible and visual alarms, and SMS push, with a warning response time of ≤2s; can accurately locate the monitoring area corresponding to the abnormal monitoring sensor module 105;

[0078] Historical data tracing unit: Supports querying historical data by time range and parameter type, generating data reports and trend analysis charts, providing data support for equipment maintenance and fault root cause analysis.

[0079] Power supply module 108 adopts DC power supply and includes a main power supply unit and a backup power supply unit, wherein:

[0080] Main power supply unit: connected to the 12V DC power supply of the cabin 102, converted to a stable 5V voltage through a power adapter, to power the monitoring sensor module 105 and the data processing module 106;

[0081] Backup power supply unit: Built-in lithium battery pack (capacity ≥50Ah), which automatically switches power supply when the main power supply is interrupted, ensuring continuous operation of the system for ≥48 hours, with power supply voltage fluctuation ≤±3%.

[0082] The working principle of this embodiment is as follows: After the system is started, a pair of monitoring sensor modules 105 start to work. Their built-in vibration detection unit, stress detection unit and temperature compensation unit work together to collect multi-physical quantity data (vibration, stress and temperature) at the connection between the hub 103 and the main shaft in the engine compartment 102. These raw data are sent to the data processing module 106 in real time through the integrated radio frequency (RF) module.

[0083] The data acquisition unit of the data processing module 106 synchronously receives parallel data streams from the two monitoring sensor modules 105; subsequently, the data preprocessing unit performs moving average filtering and standardization on the raw data to effectively remove environmental noise interference and convert the vibration, stress and temperature data into digital signals in JSON format.

[0084] The pre-processed standard format data is transmitted to the background monitoring module 107 via 4G / 5G wireless network or Ethernet. The data storage unit then completes the data reception and archiving and stores it in the distributed database.

[0085] In the background monitoring module 107, the real-time monitoring unit dynamically updates and displays the data curves of the core parameters (effective value of vibration, peak stress, ambient temperature) transmitted back by the monitoring sensor module 105, and the fault early warning unit continuously compares and analyzes the real-time data with the preset multi-dimensional fault judgment thresholds.

[0086] When any parameter detected by any monitoring sensor module 105 exceeds the safety threshold (e.g., effective vibration value > 0.6g, or peak stress > 1200με), the system immediately triggers a graded early warning mechanism, issuing an alarm through interface pop-up, audible and visual alarms, and SMS push notifications, and clearly marking the location of the abnormal sensor and its corresponding fault type.

[0087] Maintenance personnel can view real-time data and historical trends through the interface of the backend monitoring module 107. The historical traceability unit supports querying historical data by time range and parameter type, generating analysis reports and trend charts to provide data support for the formulation of maintenance plans. The system synchronously records the entire process of fault handling and updates the equipment health records to achieve closed-loop management.
