Abstract
Description
Technical Field
[0001] This utility model relates to the field of power protection and monitoring technology, specifically to an overhead line collision and anomaly monitoring device. Background Technology
[0002] Overhead power lines may be struck by foreign objects during operation, including birds, shells, and robotic arms of work vehicles. On the one hand, the collision damages the line itself, and on the other hand, it also damages the object that impacts it. When a line is subjected to collision-induced abnormality, the most direct manifestation is that the line vibrates. Monitoring and capturing this vibration signal can effectively detect whether the line has been subjected to collision-induced abnormality.
[0003] Currently, the presence of foreign objects around overhead lines in the tunnel is monitored via video surveillance. Cameras capture images of the tunnel environment to identify any foreign objects, but there's no effective method to detect whether these objects actually collide with the lines. In fact, for grounded objects like vehicles, when the line is energized, a discharge path is created even before the robotic arm collides with the line, causing a power outage and detecting the object's approach. However, it's difficult to detect collisions with overhead lines during construction or power outage maintenance. Furthermore, the accidental collisions with non-grounded objects such as birds, projectiles, and drones are difficult to detect via video.
[0004] In order to effectively monitor the process of rare birds accidentally colliding with power transmission lines and to promptly detect such behavior, it is necessary to monitor abnormal collisions with overhead lines. Utility Model Content

[0008] Preferably, the clamping mechanism comprises: two opposing semi-cylindrical housings;

[0011] Preferably, both of the semi-cylindrical shells are hollow structures, and the collision anomaly acquisition mechanism is installed in the two semi-cylindrical shells respectively.
[0012] Preferably, one end of the compression plate has a wedge-shaped structure, and the wedge-shaped structure has a through hole.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] This utility model provides an overhead line collision anomaly monitoring device, comprising: a clamping mechanism, which is fixed to the overhead conductor by a pressure plate; and a collision anomaly acquisition mechanism, which is disposed in the clamping mechanism and connected to the pressure plate. The device's clamping mechanism grips the overhead conductor. During fixing, the clamping mechanism is tightened with bolts, causing the pressure plate to move downwards and press against the overhead conductor, thus securing it. For disassembly, only the bolts need to be removed, making the device simple and easy to install and replace. The collision anomaly acquisition mechanism is integrated within the clamping mechanism, eliminating the need for separate fixing to the overhead conductor and facilitating easy assembly and disassembly. Located inside the clamping mechanism, it protects the components of the collision anomaly acquisition mechanism, preventing data distortion due to temperature and humidity changes and protecting against environmental damage such as lightning strikes or icing. The clamping mechanism also reduces interference from external noise and vibration on the detection signal. The collision anomaly acquisition mechanism measures the anomalies generated by the overhead conductor through the conduction of the pressure plate, avoiding the vibration damping provided by the rubber protection inside the clamping mechanism, greatly increasing the accuracy and sensitivity of data acquisition. The clamping mechanism and pressure plate fastening method of this device simplify installation, reducing the difficulty of high-altitude assembly, eliminating the need for power outages, and the bolts and pressure plates are adaptable to conductors of different sizes, offering strong compatibility.

[0030] Example 1:
[0031] An overhead line collision anomaly monitoring device, such as Figure 1 As shown, it includes:
[0032] The clamping mechanism 1 is fixed to the overhead conductor by the pressure plate 4;
[0033] The collision anomaly detection mechanism is installed in the clamping mechanism 1 and connected to the pressure plate 4.
[0034] The clamping mechanism 1 of the device clamps onto the overhead conductor. When fixing, the clamping mechanism 1 is tightened by bolts, and the pressure plate 4 is pressed downward to press the overhead conductor to complete the fixing. When disassembling, the device can be disassembled simply by removing the bolts. The installation method is simple and convenient for replacement.
[0035] The collision anomaly acquisition mechanism is set in the clamping mechanism 1 and does not need to be separately fixed to the overhead wire, making it easy to disassemble and assemble. The collision anomaly acquisition mechanism is set inside the clamping mechanism 1 to protect the various components of the collision movement acquisition mechanism, avoid data distortion caused by temperature and humidity changes, and prevent environmental damage such as lightning strikes or ice accumulation. At the same time, the clamping mechanism 1 can reduce the interference of external noise and vibration on the detection signal.
[0036] The collision anomaly acquisition mechanism measures the anomalies generated by the overhead conductor through the conduction of the pressure plate 4, avoiding the vibration reduction brought by the rubber protecting the inner side of the clamping mechanism 1, and greatly increasing the accuracy and sensitivity of data acquisition.
[0037] The clamping mechanism 1 and the pressure plate 4 of this device are easy to install, reducing the difficulty of high-altitude assembly. No power outage is required for construction, and the bolts and pressure plate 4 can accommodate wires of different sizes, making them highly compatible.
[0038] The collision anomaly acquisition mechanism is used to monitor the vibration of overhead power lines in real time and obtain the vibration acceleration value of the overhead power lines. When the vibration acceleration is within the limit, it is identified as a disturbance caused by wind load, and the vibration acceleration value is small and is not collected. However, when the vibration acceleration value exceeds the limit, it is identified as a collision anomaly of the overhead power lines, triggering the vibration acquisition function to collect the vibration acceleration value within three seconds and send the vibration acceleration value to the server for analysis. This allows for timely prompting of on-site problem handling and protection of the line. In the case of rare birds accidentally colliding with the line, it can promptly detect the accidental collision, carry out rescue treatment for injured birds, and protect the ecology of rare bird populations.
[0039] like Figure 2 As shown, the clamping mechanism 1 includes two opposing semi-cylindrical housings;
[0040] The two semi-cylindrical shells are hinged at one end and respectively provided with fixing holes 2 at the other end, and the two semi-cylindrical shells are fixed by bolts.
[0041] When the two semi-cylindrical shells are joined together, they can hold the overhead conductor tightly. The clamping mechanism 1 can be easily disassembled and assembled by the bolts. The tight fit provides uniform radial pressure and prevents the conductor from loosening or falling off the overhead line under wind, snow load, or external force. All components are housed in the shells, which support disassembly and reinstallation, facilitating maintenance or replacement of parts. At the same time, the shells can block rainwater and condensation from entering, protecting the vibration acquisition components and reducing the risk of corrosion.
[0042] Preferably, the two semi-cylindrical shells are provided with grooves 3, and the grooves 3 are lined with rubber.
[0043] The rubber is placed in the wire groove 3 to prevent direct fatigue wear of the wire strands at the edge of the device, prevent excessive dynamic bending strain at the outlet of the device, and prevent damage to the line after the device is installed.
[0044] Preferably, both of the semi-cylindrical shells are hollow structures, and the collision anomaly acquisition mechanism is installed in the two semi-cylindrical shells respectively.
[0045] The collision anomaly detection mechanism is installed in the two semi-cylindrical shells respectively, so that the weight on both sides is balanced and the clamping mechanism 1 is prevented from tilting or rotating.
[0046] like Figure 3 As shown, one end of the pressure plate 4 is a wedge-shaped structure, and the wedge structure is provided with a through hole 5.
[0047] The pressure plate 4 presses down on the overhead conductor to transmit vibration, preventing the vibration acquisition path from being transmitted through the rubber, which greatly increases the accuracy and sensitivity of the monitoring device's data acquisition.
[0048] Preferably, the diameter of the through hole 5 is larger than the radius of the fixing hole 2 on the semi-cylindrical shell, and when the locking bolt is tightened, the other end of the pressure plate 4 presses against the overhead conductor.
[0049] The through hole 5 on the pressure plate 4 is larger than the fixing hole 2 on the semi-cylindrical shell, providing space for the pressure plate 4 to move. When the clamping mechanism 1 is locked and fixed to the overhead conductor, under the squeezing action, the wedge-shaped structure of the pressure plate 4 slides downward and presses against the overhead conductor.
[0050] Preferably, the collision anomaly acquisition mechanism includes: a vibration sensor 6, a control circuit 7, and a battery 8 connected in sequence;
[0051] like Figure 4 As shown, the vibration sensor 6 is fixed to the other end of the pressure plate 4, as... Figure 5 and Figure 6 As shown, the control circuit 7 and the battery 8 are respectively installed in the two semi-cylindrical housings.
[0052] Preferably, the battery 8 and the control circuit 7 are parallel to each other.
[0053] Preferably, the battery 8 is a thin-film solar cell with a capacity of 10000mAh lithium iron phosphate.
[0054] The thin-film solar cell has strong power generation capability in low light conditions, and can still generate electricity on cloudy days, in the early morning or at dusk, thus improving energy utilization efficiency. At the same time, the thin-film solar cell has good anti-shading performance, and can still maintain a certain power generation efficiency when partially shaded, which is superior to traditional crystalline silicon cells.
[0055] The lithium iron phosphate battery is a high-energy-density battery with a capacity of 10,000mAh, which can store sufficient energy to meet long-term power supply needs such as outdoor equipment and emergency power. In addition, the lithium iron phosphate battery can be charged and discharged stably, supporting the fluctuating input of the solar cell and avoiding damage from overcharging / over-discharging.
[0056] Preferably, the control circuit 7 includes: a microcontroller, a power control circuit, and a communication module;
[0057] The microcontroller is connected to the communication module, the power control circuit and the vibration sensor 6 respectively;
[0058] The power control circuit is connected to the battery 8.
[0059] The microcontroller can integrate modules such as CPU, memory (ROM / RAM), timer, ADC / DAC, PWM, and communication interface (UART / IC / SPI), which greatly reduces the number of external components and circuit complexity. Its miniaturized size is suitable for compact devices, saving space.
[0060] The microcontroller also features flexible programmability, and its algorithms can be freely customized to adapt to different application needs and to address abnormal situations that may be encountered in different regions or environments.
[0061] The microcontroller has high precision and real-time performance, enabling precise control and rapid response.
[0062] The microcontroller features an anti-interference design and can adapt to harsh environments.
[0063] The control logic structure of the control circuit 7 includes: the thin-film solar cell and battery 8 provide power to the microcontroller (MCU) through the power control circuit; the vibration sensor 6 sends the obtained abnormal vibration acceleration value of the overhead conductor to the microcontroller, and the microcontroller transmits the abnormal vibration acceleration value to the communication module.
[0064] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model shall be included within the scope of the claims of this utility model pending approval.
