Description

Technical Field

[0001] This application relates to the field of power transmission line safety monitoring technology, and in particular to a real-time early warning and monitoring device for wind hazards on power transmission lines. Background Technology

[0002] Transmission lines are key facilities in the power system that undertake the task of transmitting electricity over long distances. They are widely distributed in complex geographical environments such as fields, mountains, and plains. However, these lines exposed to natural conditions are highly susceptible to the influence of weather conditions, which may cause severe wind-induced swaying or even periodic large-scale galloping of conductors. This may not only lead to insufficient air gap between the conductor and nearby objects, causing discharge tripping, but also cause serious accidents such as hardware damage, conductor strand breakage, and tower collapse. Therefore, it is necessary to conduct real-time early warning and monitoring of wind hazards on transmission lines. By capturing abnormal wind conditions in real time and issuing early warnings, valuable emergency response time can be gained for operation and maintenance personnel, thereby preventing or reducing power outage accidents caused by wind hazards.

[0003] In conventional technologies, monitoring of wind damage to transmission lines typically relies on specialized monitoring devices installed on towers. These devices generally consist of sensor units, data acquisition and processing units, communication units, and power supply units. The sensor unit is the sensing front end, usually including wind speed and direction sensors, used to directly measure environmental wind field parameters. The data acquisition and processing unit, as the core, is responsible for receiving signals from various sensors, performing analog-to-digital conversion, preliminary calculations, and data storage. The communication unit is responsible for remotely transmitting the processed data to the back-end system of the monitoring center. The power supply unit often uses solar panels in conjunction with batteries to provide continuous power for the entire device working in the field. These structural components together constitute a monitoring node capable of collecting, processing, and reporting on-site wind damage-related data.

[0004] Regarding the aforementioned technologies, since relying solely on wind speed and direction sensors to measure environmental wind field parameters may not be sufficient to directly and accurately detect key information such as the sway amplitude, vibration frequency, and spatial trajectory of the line itself under wind action, it is difficult to accurately determine the damage caused by strong winds to the line based on wind speed data alone, resulting in insufficient early warning accuracy and the inability to issue highly targeted alarms in a timely manner before danger occurs. Therefore, improvements are needed. Utility Model Content

[0005] In order to monitor and warn of the amplitude, frequency and direction of power transmission line swaying in real time, this application provides a real-time early warning and monitoring device for wind damage to power transmission lines.

[0006] The wind damage early warning and monitoring device for power transmission lines provided in this application adopts the following technical solution: A real-time early warning and monitoring device for wind damage to power transmission lines includes a base station and a power transmission line. Multiple sets of base stations and power transmission lines are provided, and adjacent base stations are sequentially connected by the power transmission lines. Each base station is equipped with a mounting frame, and meteorological sensors are mounted on the side walls of the mounting frame. The mounting frame also houses a data receiver and a host computer for processing the data received by the data receiver and uploading it to a management platform. Both the meteorological sensors and the data receiver are electrically connected to the host computer. The upper end of the mounting frame is equipped with a monitoring mechanism for real-time monitoring of the amplitude, frequency, and direction of the power transmission line's sway.

[0007] By adopting the above technical solution, the meteorological sensor in this application can monitor the wind direction, wind speed, temperature, humidity, and rainfall of the environment where the transmission line is located. The detection mechanism on the mounting frame can monitor the amplitude, frequency, and direction of the transmission line sway in real time. The meteorological sensor and the detection mechanism transmit the collected data to the data receiver, which processes the data and transmits it to the host. The host uploads the data to the management platform via the network on a periodic basis. When the monitored value exceeds the preset threshold, the host automatically issues an early warning and triggers an instruction to the front-end personnel. This enables real-time monitoring and early warning of the amplitude, frequency, and direction of the transmission line sway, improving response timeliness and operational initiative, and reducing reliance on manual labor and costs.

[0008] Optionally, the monitoring mechanism includes a line monitoring component and a video monitoring component. The video monitoring component is mounted on the mounting frame and is used for real-time monitoring and video recording of the transmission line. Three sets of the line monitoring components are spaced apart on the transmission line between adjacent base stations. The three sets of line monitoring components are located in the middle of the transmission line and at both ends near the base stations, respectively. The line monitoring component includes a mounting block, a fastening cover, an inertial sensor, a wireless transmitter, a snap-fit ​​rod, a pressing rod, and an anti-rotation component. The mounting block is located below the transmission line. The fastening cover is hinged to the upper end of the mounting block. The inertial sensor and the wireless transmitter are both located at the lower end of the mounting block and are electrically connected. The snap-fit ​​rod is located at the end of the fastening cover away from the end hinged to the mounting block. The mounting block has a snap-fit ​​groove for snapping the snap-fit ​​rod into the mounting block. The mounting block also has a sliding groove. The pressing rod is slidably disposed in the sliding groove and moves in contact with the snap-fit ​​rod. When the pressing rod contacts the snap-fit ​​rod and continues to press, the snap-fit ​​rod can disengage from the snap-fit ​​groove. The anti-rotation component is disposed at the upper end of the mounting block to reduce the relative rotation angle and offset distance between the mounting block and the transmission line.

[0009] By adopting the above technical solution, when the mounting block needs to be installed on the transmission line, the mounting block is placed under the transmission line, the fastening cover is rotated and the locking rod is engaged with the locking slot, thereby engaging the fastening cover with the mounting block, and the mounting block is installed on the transmission line. Since both the inertial sensor and the wireless transmitter are fixedly mounted on the mounting block, the inertial sensor can monitor the amplitude, frequency and direction of the transmission line swing in real time and transmit the monitoring data to the wireless transmitter. The wireless transmitter transmits the data to the data receiver and the host, providing core data support for accurate early warning and buying time for key decisions such as initiating emergency dispatch and organizing emergency repairs. This reduces the potential power outage area and equipment damage caused by disasters. Furthermore, the three sets of line monitoring components can simultaneously acquire the dynamic response of different sections of the transmission line, achieving comprehensive perception of key characteristics such as galloping waveforms and amplitude distribution, thus avoiding the limitations of single-point monitoring. When the mounting block needs to be disassembled, pressing the pressing rod causes it to slide within the movable groove. After the pressing rod abuts against the locking rod, continued pressing disengages the locking rod from the locking groove, preventing the fastening cover from locking the mounting block, allowing for disassembly of the mounting block. This improves the efficiency of equipment maintenance and replacement, and reduces the risks and costs of operation and maintenance.

[0010] Optionally, the anti-rotation component includes a limiting frame and a snap-fit ​​block. The limiting frame is disposed on the outer peripheral wall of the transmission line, and the snap-fit ​​block is disposed on the upper end of the mounting block. A limiting groove is formed on the limiting frame, and the snap-fit ​​block is movably snapped into the limiting groove.

[0011] By adopting the above technical solution, when installing the mounting block and the transmission line, the snap-fit ​​block is first aligned with the limiting groove on the limiting frame and snapped in place. After snapping in place, the fastening cover is then snapped in place. When the snap-fit ​​block is snapped in place with the limiting groove on the limiting frame, the limiting groove can prevent the snap-fit ​​block and the limiting frame from relative offset and rotation, thereby reducing the relative rotation angle and offset distance between the inertial sensor and the mounting block and the transmission line, and thus improving the accuracy and reliability of the inertial sensor in monitoring the amplitude, frequency and direction of the transmission line swing.

[0012] Optionally, the video surveillance component includes a camera, a mounting base, a first stepper motor, and a pitch adjustment component. The first stepper motor is disposed on the inner top wall of the mounting frame, and its output end extends through the mounting frame. The mounting base is disposed on the output end of the first stepper motor. The camera is disposed on the mounting base, and the pitch adjustment component is disposed on the mounting base for adjusting the pitch of the camera.

[0013] By adopting the above technical solution, when the camera needs to monitor the power transmission lines on both sides of the base station in sequence, the first stepper motor is started. The output end of the first stepper motor rotates, which drives the mounting base to rotate. The rotation of the mounting base drives the camera to rotate horizontally, thereby realizing real-time monitoring and video recording of the power transmission lines, expanding the monitoring range, and enabling monitoring and observation of a certain part of the power transmission line or base station based on the signal from the management platform.

[0014] Optionally, the pitch adjustment component includes a second stepper motor and a rotating block. The second stepper motor is mounted on the mounting base, and the rotating block is mounted on the output end of the second stepper motor. The rotating block is fixedly connected to the camera, and the mounting base has a rotating groove for the rotating block to perform pitch rotation.

[0015] By adopting the above technical solution, when it is necessary to adjust the tilt angle of the camera, the second stepper motor is started. The output end of the second stepper motor rotates, causing the rotating block to rotate in the rotating groove of the mounting base. The rotation of the rotating block causes the camera to tilt, thereby realizing the tilt adjustment of the camera according to the monitoring needs. It also realizes real-time monitoring of power transmission lines from multiple angles without blind spots, improving the comprehensiveness and flexibility of the monitoring range.

[0016] Optionally, friction pads are provided between the mounting block, the fastening cover, and the limiting frame and the transmission line to reduce the relative rotation angle and offset distance with the transmission line.

[0017] By adopting the above technical solution, the friction pad can increase the friction between the mounting block, fastening cover and limiting frame and the transmission line, thereby suppressing the relative displacement and rotation between the inertial sensor and the transmission line, improving the accuracy of monitoring data and enhancing the stability of the structure.

[0018] Optionally, the mounting bracket, the mounting block, and the mounting base are all provided with protective shells.

[0019] By adopting the above technical solutions, the protective shell can provide all-round protection, reduce the erosion of rain, snow and dust, and improve the long-term durability and data acquisition reliability of the equipment in the field environment.

[0020] Optionally, the lower end of the protective shell on the mounting block has multiple sets of heat dissipation holes.

[0021] By adopting the above technical solution, the heat dissipation holes at the bottom can effectively dissipate heat from inside the equipment while ensuring protection, thereby improving the accuracy of monitoring data and operational stability.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The line monitoring component in this application can monitor the amplitude, frequency, and direction of transmission line swaying in real time. The mounting block is placed under the transmission line, and the fastening cover is rotated to make the clamping rod engage with the clamping slot, thereby engaging the fastening cover with the mounting block, that is, the mounting block is installed on the transmission line. Therefore, the inertial sensor on the mounting block can monitor the amplitude, frequency, and direction of transmission line swaying in real time and transmit the monitoring data to the wireless transmitter. The wireless transmitter transmits the data to the data receiver and the host, providing core data support for accurate early warning and buying time for key decisions such as initiating emergency dispatch and organizing emergency repairs. This reduces the potential power outage area and equipment damage caused by disasters. Furthermore, the three sets of line monitoring components can simultaneously acquire the dynamic response of different sections of the transmission line, achieving comprehensive perception of key characteristics such as galloping waveforms and amplitude distribution, thus avoiding the limitations of single-point monitoring. When the mounting block needs to be disassembled, pressing the pressing rod causes it to slide within the movable groove. After the pressing rod abuts against the locking rod, further pressing causes the locking rod to disengage from the locking groove, thereby preventing the fastening cover from locking the mounting block and allowing for disassembly. This improves the efficiency of equipment maintenance and replacement, and reduces the risks and costs of operation and maintenance. 2. The anti-rotation component in this application can reduce the relative rotation angle and offset distance between the mounting block and the transmission line. When installing the mounting block and the transmission line, first align the snap-fit ​​block with the limiting groove on the limiting frame and snap it in place. After snapping in place, snap the fastening cover in place. The snap-fit ​​between the snap-fit ​​block and the limiting groove can prevent the snap-fit ​​block and the limiting frame from offsetting and rotating relative to each other, thereby reducing the relative rotation angle and offset distance between the inertial sensor and the mounting block and the transmission line, and thus improving the accuracy and reliability of the inertial sensor in monitoring the amplitude, frequency and direction of the transmission line swing. 3. The video surveillance component in this application performs real-time monitoring and video recording of power transmission lines. Starting the first stepper motor causes it to rotate, driving the mounting base and camera to rotate horizontally, thereby enabling real-time monitoring and video recording of the power transmission lines, expanding the monitoring range. It can also monitor and observe specific locations on the power transmission line or base station based on signals from the management platform. When the camera's tilt angle needs adjustment, starting the second stepper motor causes it to rotate, driving the rotating block and camera within the rotating slot of the mounting base. This allows for tilt adjustment of the camera according to monitoring requirements, achieving multi-angle, blind-spot-free real-time monitoring of the power transmission lines, improving the comprehensiveness and flexibility of the monitoring range.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses a real-time early warning and monitoring device for wind hazards on power transmission lines, referring to... Figure 1 and Figure 3 A real-time early warning and monitoring device for wind damage to power transmission lines includes a base station and a power transmission line. Multiple sets of base stations and power transmission lines are provided, and adjacent base stations are connected sequentially by the power transmission lines. A mounting frame 1 is bolted to the base station. A meteorological sensor 11 is fixedly installed on the side wall of the mounting frame 1. A data receiver 12 and a host 13 are fixedly installed on the mounting frame 1. The meteorological sensor 11 and the data receiver 12 are both electrically connected to the host 13. A monitoring mechanism is installed at the upper end of the mounting frame 1.

[0028] The meteorological sensor 11 in this embodiment can monitor the wind direction, wind speed, temperature, humidity, and rainfall of the environment where the transmission line is located. The detection mechanism on the mounting frame 1 can monitor the amplitude, frequency, and direction of the transmission line sway in real time. The meteorological sensor 11 and the detection mechanism transmit the collected data to the data receiver 12. The data receiver 12 processes the data and transmits it to the host 13. The host 13 uploads the data to the management platform via the network periodically. When the monitored value exceeds the preset threshold, the host 13 automatically issues an early warning and triggers an instruction to the front-end staff, thereby realizing real-time monitoring and early warning of the amplitude, frequency, and direction of the transmission line sway, improving response timeliness and operational initiative, and reducing reliance on manual labor and costs.

[0029] Reference Figure 4 , Figure 5 and Figure 6 In order to monitor the amplitude, frequency and direction of the sway of the transmission line in real time, the monitoring mechanism in this embodiment includes a line monitoring component 2 and a video monitoring component 4. The video monitoring component 4 is installed on the mounting frame 1. Three sets of line monitoring components 2 are installed at intervals on the transmission line between adjacent base stations. The three sets of line monitoring components 2 are located in the middle of the transmission line and at both ends near the base stations. The line monitoring component 2 includes a mounting block 21, a fastening cover 22, an inertial sensor 23, a wireless transmitter 24, a snap-fit ​​rod 25, a pressing rod 26 and an anti-rotation component 3. The mounting block 21 is installed below the transmission line. The fastening cover 22 is hinged to the upper end of the mounting block 21. The inertial sensor 23 and the wireless transmitter 24 are both fixedly installed at the lower end of the mounting block 21 and are electrically connected. The locking rod 25 is installed on the end of the fastening cover 22 away from the hinged connection with the mounting block 21. The mounting block 21 has a locking groove 27 and a sliding groove 28. The pressing rod 26 is slidably installed in the sliding groove 28 and moves in contact with the locking rod 25. When the pressing rod 26 abuts against the locking rod 25 and continues to press, the locking rod 25 can be disengaged from the locking groove 27. The anti-rotation component 3 is installed on the upper end of the mounting block 21.

[0030] When the mounting block 21 needs to be installed on the power transmission line, place the mounting block 21 under the power transmission line, rotate the fastening cover 22 and make the snap-fit ​​rod 25 snap into the snap-fit ​​groove 27, so that the fastening cover 22 and the mounting block 21 are snapped into place, that is, the mounting block 21 is installed on the power transmission line. Since the inertial sensor 23 and the wireless transmitter 24 are both fixedly installed on the mounting block 21, the inertial sensor 23 can monitor the amplitude, frequency and direction of the power transmission line swing in real time and transmit the monitoring data to the wireless transmitter 24. The wireless transmitter 24 transmits the data to the data receiver 12 and the host 13, providing core data support for accurate early warning and buying time for key decisions such as initiating emergency dispatch and organizing emergency repairs, reducing the scope of power outages and equipment damage that may be caused by disasters. Furthermore, the three sets of line monitoring components can simultaneously acquire the dynamic response of different sections of the transmission line, achieving comprehensive perception of key characteristics such as galloping waveforms and amplitude distribution, thus avoiding the limitations of single-point monitoring. When it is necessary to disassemble the mounting block 21, the pressing rod 26 is pressed, causing it to slide within the movable groove 28. After the pressing rod 26 abuts against the locking rod 25, pressing continues to disengage the locking rod 25 from the locking groove 27, thereby preventing the fastening cover 22 from locking the mounting block 21. This allows the mounting block 21 to be disassembled, improving the efficiency of equipment maintenance and replacement, and reducing the risks and costs of operation and maintenance. In this embodiment, the mounting block 21 is equipped with a lithium battery pack and a solar charging panel, thereby enabling the long-term operation of the line monitoring component 2. In this embodiment, the fastening cover 22 has a movable groove, and the snap-fit ​​rod 25 is slidably installed in the movable groove. A spring is fixedly connected to the inner wall of the movable groove, and the end of the spring away from the movable groove is fixedly connected to the snap-fit ​​rod 25. When the pressing rod 26 presses the snap-fit ​​rod 25, the snap-fit ​​rod 25 compresses the spring and slides in the movable groove, thereby causing the snap-fit ​​rod 25 to disengage from the snap-fit ​​groove 27, and thus preventing the mounting block 21 from snapping into the fastening cover 22.

[0031] Reference Figure 2 and Figure 3 When the wind speed reaches a certain threshold, the mounting block 21 and the power transmission line may rotate and shift relative to each other. Therefore, the anti-rotation component 3 in this embodiment includes a limiting frame 31 and a snap-fit ​​block 32. The limiting frame 31 is fixedly installed on the outer peripheral wall of the power transmission line, and the snap-fit ​​block 32 is fixedly installed on the upper end of the mounting block 21. A limiting groove 33 is provided on the limiting frame 31, and the snap-fit ​​block 32 is movably snapped into the limiting groove 33.

[0032] When installing the mounting block 21 with the transmission line, first align the snap-fit ​​block 32 with the limiting groove 33 on the limiting frame 31 and snap it in place. After snapping in place, snap the fastening cover 22 in place. When the snap-fit ​​block 32 is snapped in place with the limiting groove 33 on the limiting frame 31, the limiting groove 33 can prevent the snap-fit ​​block 32 and the limiting frame 31 from relative offset and rotation, thereby reducing the relative rotation angle and offset distance between the inertial sensor 23 and the mounting block 21 and the transmission line, and thus improving the accuracy and reliability of the inertial sensor 23 in monitoring the amplitude, frequency and direction of the transmission line swing. In this embodiment, the anti-rotation component 3 is symmetrically arranged in two sets. The two sets of anti-rotation components 3 can further reduce the relative rotation angle and offset distance. In this embodiment, the limiting frame 31 is composed of two sets of adjustable clamps, which can be tightly installed on the outer peripheral wall of the transmission line and facilitate installation and disassembly.

[0033] Reference Figure 2 and Figure 3 In order to monitor and record power transmission lines in real time, the video monitoring component 4 in this embodiment includes a camera 41, a mounting base 42, a first stepper motor 43, and a pitch adjustment component 5. The first stepper motor 43 is bolted to the inner top wall of the mounting frame 1, and its output end is set through the mounting frame 1. The mounting base 42 is fixedly installed on the output end of the first stepper motor 43. The camera 41 is fixedly installed on the mounting base 42, and the pitch adjustment component 5 is installed on the mounting base 42.

[0034] When the camera 41 needs to monitor the power transmission lines on both sides of the base station in sequence, the first stepper motor 43 is started. The output end of the first stepper motor 43 rotates, which drives the mounting base 42 to rotate. The rotation of the mounting base 42 drives the camera 41 to rotate horizontally, thereby realizing real-time monitoring and video recording of the power transmission lines, expanding the monitoring range, and enabling monitoring and observation of a certain part of the power transmission line or base station based on the signal from the management platform.

[0035] Reference Figure 3 The pitch adjustment component 5 in this embodiment includes a second stepper motor 51 and a rotating block 52. The second stepper motor 51 is bolted to the mounting base 42, and the rotating block 52 is fixedly installed on the output end of the second stepper motor 51. The rotating block 52 is fixedly connected to the camera 41, and the mounting base 42 has a rotating groove 53. When it is necessary to adjust the pitch angle of the camera 41, the second stepper motor 51 is started. The output end of the second stepper motor 51 rotates, causing the rotating block 52 to rotate in the rotating groove 53 of the mounting base 42. The rotation of the rotating block 52 causes the camera 41 to rotate in pitch, thereby realizing the pitch adjustment of the camera 41 according to the monitoring requirements. It also realizes real-time monitoring of the transmission line from multiple angles without blind spots, improving the comprehensiveness and flexibility of the monitoring range.

[0036] Reference Figure 1 and Figure 4 To suppress the relative displacement and rotation between the inertial sensor 23 and the transmission line, friction pads are provided between the mounting block 21, the fastening cover 22, and the limiting frame 31 and the transmission line in this embodiment. The friction pads can increase the friction between the mounting block 21, the fastening cover 22, and the limiting frame 31 and the transmission line, thereby improving the accuracy of the monitoring data and enhancing the stability of the structure. The friction pads in this embodiment are made of silicone rubber, which is a preferred material in this embodiment. They can also be made of materials such as neoprene rubber and polyurethane.

[0037] Reference Figure 2 and Figure 4 Rain, snow, dust, and birds may damage the monitoring device. Therefore, in this embodiment, the mounting frame 1, mounting block 21, and mounting base 42 are all equipped with protective shells 6. The protective shells 6 can provide all-round protection, reduce the erosion of rain, snow, and dust, and improve the long-term durability and data acquisition reliability of the equipment in the field environment.

[0038] Reference Figure 4 In this embodiment, the protective shell 6 on the mounting block 21 has multiple sets of heat dissipation holes 7 at its lower end. The heat dissipation holes 7 at the lower end effectively dissipate heat from inside the equipment while ensuring protection, thereby improving the accuracy of monitoring data and operational stability.

[0039] The implementation principle of the all-time early warning and monitoring device for wind damage to power transmission lines in this application embodiment is as follows: The mounting block 21 is placed under the transmission line, and the fastening cover 22 is rotated to engage the locking rod 25 with the locking slot 27, thereby engaging the fastening cover 22 with the mounting block 21. This installs the mounting block 21 onto the transmission line. Therefore, the inertial sensor 23 on the mounting block 21 can monitor the amplitude, frequency, and direction of the transmission line's sway in real time and transmit the monitoring data to the wireless transmitter 24. The wireless transmitter 24 transmits the data to the data receiver 12 and the host 13, providing core data support for accurate early warning. Furthermore, the three sets of line monitoring... The measuring component can simultaneously acquire the dynamic response of different sections of the transmission line, realizing comprehensive perception of key features such as galloping waveform and amplitude distribution, avoiding the limitations of single-point monitoring; when it is necessary to disassemble the mounting block 21, press the pressing rod 26 to make the pressing rod 26 slide in the movable groove 28. After the pressing rod 26 abuts against the locking rod 25, continue pressing to make the locking rod 25 disengage from the locking groove 27, so that the fastening cover 22 and the mounting block 21 are not locked, and the mounting block 21 can be disassembled, improving the efficiency of equipment maintenance and replacement; When installing the mounting block 21 and the transmission line, first align the snap-fit ​​block 32 with the limiting groove 33 on the limiting frame 31 and snap it in place. After snapping in place, snap the fastening cover 22 in place. The snap-fit ​​between the snap-fit ​​block 32 and the limiting groove 33 can prevent the snap-fit ​​block 32 and the limiting frame 31 from relative offset and rotation, thereby reducing the relative rotation angle and offset distance between the inertial sensor 23 and the mounting block 21 and the transmission line, and thus improving the accuracy and reliability of the inertial sensor 23 in monitoring the amplitude, frequency and direction of the transmission line swing. The first stepper motor 43 is started, and its rotation drives the mounting base 42 and camera 41 to rotate horizontally, thereby enabling real-time monitoring and video recording of the transmission line, expanding the monitoring range, and allowing monitoring and observation of a specific location on the transmission line or base station based on signals from the management platform. When it is necessary to adjust the pitch angle of the camera 41, the second stepper motor 51 is started, and its rotation drives the rotating block 52 and camera 41 to rotate within the rotating slot 53 of the mounting base 42, thereby enabling pitch adjustment of the camera 41 according to monitoring needs, and achieving real-time monitoring of the transmission line from multiple angles without blind spots, improving the comprehensiveness and flexibility of the monitoring range.
