Description

Technical Field

[0001] This invention relates to the technical field of online lightning rod monitoring devices, specifically a real-time online monitoring device for the swing distance of a lightning rod. Background Technology

[0002] As a key component of lightning protection systems, the installation stability of lightning rods in substations directly affects the reliability of the overall lightning protection effectiveness. During long-term outdoor operation, lightning rods are continuously subjected to erosion from natural factors such as strong winds, heavy rains, and earthquakes, making them prone to safety hazards such as loose bolts, structural deformation, and foundation settlement. Especially in calm wind conditions, conventional testing methods are insufficient to detect hidden loose bolt connections or accurately assess whether the lightning rod's swing amplitude is within a safe range. If the swing amplitude exceeds the safe threshold and is not detected in time, it may lead to the lightning rod tipping over or the lightning protection function failing, resulting in serious equipment damage and safety accidents.

[0003] Currently, the monitoring of lightning rods in substations mainly relies on regular manual inspections, a traditional method with several limitations. First, the inspection cycle is long, making real-time monitoring of the lightning rod's condition impossible and failing to detect sudden abnormal swinging. Second, manual measurement methods have low accuracy and are easily affected by subjective factors such as environmental conditions and the operator's skill level, leading to significant errors in the data. Furthermore, for lightning rods on tall buildings, traditional manual inspections or drone-assisted inspections face high operational risks, operational difficulties, and high maintenance costs, making it difficult to establish a systematic and standardized monitoring system.

[0004] Existing monitoring technologies generally lack comprehensive data traceability and analysis capabilities, making it impossible to establish long-term trend models for lightning rod sway amplitude. This data gap makes it difficult for maintenance personnel to conduct predictive analysis of potential faults, forcing them to rely on post-incident handling and hindering the shift from reactive maintenance to proactive prevention. Furthermore, the lack of historical data makes it impossible to scientifically assess the structural aging of lightning rods and changes in bolt tightness, resulting in a lack of basis for equipment maintenance planning and further increasing the difficulty of safety risk management. This insufficient monitoring capability has become a significant bottleneck restricting the improvement of intelligent operation and maintenance levels in substations. Summary of the Invention

[0005] This invention provides a real-time online monitoring device for lightning rod swing distance, which overcomes the shortcomings of the prior art and can effectively solve the problems of untimely monitoring of lightning rods in existing substations, which pose safety hazards and cause equipment damage.

[0006] The technical solution of the present invention is achieved through the following measures: a real-time online monitoring device for lightning rod swing distance, comprising a monitoring module, the monitoring module comprising an insulating protective shell, the insulating protective shell being installed inside the upper part of a supporting steel frame, the insulating protective shell being coaxially arranged with the lightning rod, the insulating protective shell containing a microcontroller, a wireless communication module, a swing amplitude monitoring sensor, and a battery, the insulating protective shell having a wind speed sensor installed on the upper side, the wind speed sensor and the swing amplitude monitoring sensor being connected to the microcontroller, the microcontroller being connected to the wireless communication module, the wireless communication module being connected to a base station, and the base station being connected to a background monitoring system.

[0007] The following are further optimizations and / or improvements to the above-mentioned technical solution: Preferably, the swing amplitude monitoring sensor is a high-frequency accelerometer. The high-frequency accelerometer swings synchronously with the lightning rod, generating acceleration in the horizontal direction and outputting acceleration data. The microcontroller integrates the acceleration data twice. 'a' represents acceleration. The acceleration data is converted into displacement, and the displacement error after integration can be controlled within 0.1 mm through digital filtering.

[0008] Preferably, the sway amplitude monitoring sensor is a dual-axis tilt sensor that collects the offset angle during the sway of the lightning rod. The microcontroller performs calculations. , H represents the horizontal swing distance, and H represents the height of the lightning rod. Calculate the actual horizontal swing distance based on the offset angle.

[0009] Preferably, it also includes insulators, and the insulating protective shell is installed inside the supporting steel frame through the insulators.

[0010] Preferably, it also includes a flexible solar panel, with the flexible solar panel covering the outside of the insulating protective shell, and the flexible solar panel being connected to the battery.

[0011] Preferably, the microcontroller has a built-in real-time clock (RTC) and a GPS device installed inside an insulated protective housing. The GPS time is written into the microcontroller's RTC register, and the RTC clock is triggered every second by the GPS PPS signal to correct the RTC time deviation.

[0012] This invention has a reasonable and compact structure and is easy to use. It monitors the swing of the lightning rod in real time through a swing amplitude monitoring sensor, and combines the data from the wind speed sensor to determine whether the swing amplitude of the lightning rod exceeds the threshold. If the swing is abnormal and exceeds the threshold, it needs to be alerted for maintenance, so as to detect it in time and reduce safety accidents. Attached Figure Description

[0013] Appendix Figure 1 This is a schematic diagram of the main structure of an embodiment of the present invention.

[0014] Appendix Figure 2 For the appendix Figure 1 A magnified structural diagram of the monitoring module in the image.

[0015] Appendix Figure 3 This is a connection diagram for the microcontroller.

[0016] The codes in the attached diagram are as follows: 1 for the supporting steel frame, 2 for the insulating protective shell, 3 for the lightning rod, 4 for the wind speed sensor, and 5 for the insulator. Detailed Implementation

[0017] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0018] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0019] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1-3 As shown, the real-time online monitoring device for lightning rod swing distance includes a monitoring module, which includes an insulating protective shell 2. The insulating protective shell 2 is installed inside the upper part of the supporting steel frame 1 and is coaxially arranged with the lightning rod 3. The insulating protective shell 2 contains a microcontroller, a wireless communication module, a swing amplitude monitoring sensor, and a battery. A wind speed sensor 4 is installed on the upper side of the insulating protective shell 2. The wind speed sensor 4 and the swing amplitude monitoring sensor are both connected to the microcontroller. The microcontroller is connected to the wireless communication module, the wireless communication module is connected to the base station, and the base station is connected to the background monitoring system.

[0020] The main structure of the lightning rod includes section A0, which is the lightning rod 3's lightning conductor; sections A, B, C, D, E, and F1 are all supporting steel frames 1 (down conductors). The monitoring module is installed inside the supporting steel frame 1 in section A via an insulating component. The monitoring module is not in direct contact with the supporting steel frame 1; the monitoring module and the lightning rod 3 are coaxially arranged. When the lightning rod 3 swings, the supporting steel frame 1 and the monitoring module swing synchronously. The swing amplitude monitoring sensor directly monitors the swing distance of the monitoring module, thereby monitoring the swing distance of the lightning rod 3. By measuring the wind speed data, the microcontroller receives and processes the sensor data and then... The wireless communication module transmits data to the base station, which in turn transmits it to the backend monitoring system. This generates a curve showing the change in the swing amplitude, which is compared to a preset safe swing distance threshold at the current wind speed (e.g., ≤26mm for wind speeds of 0-5m / s). When the swing amplitude exceeds the safe swing distance threshold allowed at the current wind speed, it indicates loose bolts, excessive deformation of the lightning rod 3 reinforcement, or foundation collapse. The early warning module immediately sends an alarm to relevant management personnel. Management personnel can then view real-time data, historical records, and alarm details through the backend monitoring system and promptly arrange maintenance. This allows for early detection of the risk of the lightning rod 3 tipping over or lightning protection failure, reducing the risk of serious equipment damage and safety accidents. Real-time monitoring reduces the difficulty of inspections and minimizes safety hazards. Compared to existing manual periodic inspections, which have long cycles, low measurement accuracy, and the inability to promptly detect loose screws, are affected by environmental conditions and operator skill levels, and cannot capture sudden swaying anomalies in real time, this technology offers shorter inspection cycles and can capture sudden swaying anomalies in real time. Compared to drone aerial inspections, which are difficult and costly to operate, are affected by weather, and have the risk of drone crashes affecting the safe operation of equipment in the substation, this technology is simpler, cheaper, and unaffected by weather. In fact, the stronger the wind, the more accurately the monitoring data reflects the risk of tower collapse.

[0021] The above-mentioned real-time online monitoring device for lightning rod swing distance can be further optimized and / or improved according to actual needs: Example 2: As shown in the attached document Figure 3 As shown, the swing amplitude monitoring sensor is a high-frequency accelerometer. The high-frequency accelerometer swings synchronously with the lightning rod 3, generating acceleration in the horizontal direction and outputting acceleration data. The microcontroller integrates the acceleration data twice. 'a' represents acceleration. The acceleration data is converted into displacement, and the displacement error after integration can be controlled within 0.1 mm through digital filtering.

[0022] By using a high-frequency accelerometer sensor to detect the acceleration data of the monitoring module when it swings synchronously with the lightning rod 3, and then using a microcontroller to calculate the swing displacement data, the data is transmitted to the background monitoring system to obtain the swing distance parameter of the lightning rod 3.

[0023] Example 3: As shown in the attached document Figure 3 As shown, the swing amplitude monitoring sensor is a dual-axis tilt sensor, which collects the offset angle of the lightning rod 3 during its swing. The microcontroller performs calculations. , H represents the horizontal swing distance, and H represents the height of the lightning rod. Calculate the actual horizontal swing distance based on the offset angle.

[0024] By using a dual-axis tilt sensor to detect the acceleration data of the monitoring module when it swings synchronously with the lightning rod 3, and then using a microcontroller to calculate the swing displacement data, the data is transmitted to the background monitoring system to obtain the swing distance parameter of the lightning rod 3.

[0025] Example 4: As shown in the appendix Figure 2 As shown, it also includes an insulator 5, and the insulating protective shell 2 is installed inside the supporting steel frame 1 via the insulator 5. The insulator 5 enhances the insulation of the monitoring module and facilitates connection with the supporting steel frame 1.

[0026] Example 5: As shown in the attached document Figure 1 , 3 As shown, it also includes a flexible solar panel, which is covered on the outside of the insulating protective casing 2 and connected to the battery. The flexible solar panel can provide power to other components, reducing power supply costs and the frequency of battery replacements.

[0027] Example 6: As shown in the appendix Figure 1 , 3 As shown, the microcontroller has a built-in real-time clock (RTC), and a GPS device is installed inside the insulated protective housing 2. The GPS time is written into the microcontroller's RTC register, and the RTC clock is triggered every second via the GPS PPS signal to correct the RTC time deviation. The GPS can locate the position of the lightning rod 3 and also obtain accurate time in real time via satellite to correct the RTC time inside the microcontroller, ensuring accurate monitoring time.

[0028] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
