Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line detection, and in particular to a wind deviation detection and early warning system for a tower line system of a power transmission line and an evaluation method. Background Art

[0002] Wind deflection of transmission lines is a phenomenon of conductor swinging caused by wind, which poses a serious threat to the safe operation of the line. Wind deflection includes jumper wind deflection, phase-to-phase wind deflection and insulator wind deflection. Jumper wind deflection refers to the fact that the jumper on the corner tower is affected by strong winds, which shortens the distance between the jumper and the corner tower, resulting in jumper discharge; phase-to-phase wind deflection refers to the electrical distance between the conductors shortened under strong wind conditions, resulting in discharge between conductors of different phases; insulator wind deflection angle refers to the inclination angle of the insulator string relative to the tower under the action of wind. Among them, insulator string wind deflection is the most important factor causing wind deflection tripping accidents. The direct cause of wind deflection tripping accidents is that the wind deflection angle of the suspended insulator string is too large. When the wind deflection angle is too large, it is easy to cause the air gap between the charged body at the lower end of the insulator string and the iron tower to decrease. When the electrical strength of this gap cannot withstand the system operating voltage, discharge will occur.

[0003] Wind deviation can cause phase-to-phase flashover and metal fixture damage, or even lead to line tripping, power outage, tower collapse, wire breakage and other serious accidents, resulting in significant economic losses. Therefore, it is of great significance to conduct online monitoring of transmission lines to prevent wind deviation. The wind deviation monitoring system is used to monitor the wire swing caused by wind. By real-time monitoring and analysis of wind deviation, it can effectively prevent and reduce the occurrence of wind deviation accidents. This system can detect and warn possible wind deviation problems in a timely manner by monitoring parameters such as wire swing and insulator string tilt angle.

Before the strong wind comes, it is judged whether the transmission line is safe and reliable under strong wind, and its safety margin is obtained, and an early warning is given.

[0018] The present invention also provides an evaluation method for a wind deviation detection and early warning system for a power transmission line tower line system, comprising the following steps: S1. Installation of early warning system The fixing plate is fixedly mounted on the transmission line tower and ensured to be in a horizontal plane; S2. Installation of working box The docking block is docked with the movable column, so that the working box falls under its own weight, at which time the movable column moves relative to the fixed column, and the rotating rod rotates relative to the fixed column, thereby preliminarily installing the working box; S3.

[0020] Compared with the prior art, the present invention has the following beneficial effects: (1) The user can initially place the work box by docking the docking block with the moving column. After the work box is placed, the work box will drive the moving column to move down along the fixed column under the influence of its own gravity. At this time, the fixed column will push the gear block to move down synchronously. When the gear block moves down, it will synchronously drive the rotating rod to rotate through the gear ring engaged with it. At this time, the rotating rod can rotate inward synchronously. The auxiliary plate set on the upper side of the rotating rod contacts the lower side of the placement plate set at the lower end of the work box, thereby increasing the support range of the work box and improving the stability of the placement of the work box.

[0021] (2) When the auxiliary plate contacts the lower side of the placement plate, the rotating rod continues to rotate, which will drive the threaded rod hinged to it to move upward along the movable groove. At the same time, the threaded rod will enter the interior of the stabilizing rod. The stabilizing rod will rotate synchronously under the action of the threaded connection with the threaded rod and nest into the interior of the stabilizing groove, thereby further limiting the docking block, improving the stability of the work box placement, reducing the use of bolts, and allowing the work box to be quickly installed and disassembled.

[0022] (3) Since the limit block moves within the limit groove under the drive of the stabilizer bar, the outer end of the stabilizer bar can be stably rotated and embedded in the stabilizer groove opened on the side of the docking block, further improving the stability of the stabilizer bar during rotation.

[0023] (4) The fan is affected by the external wind force and will drive the driving roller to rotate synchronously. At this time, the driving roller will drive the driving ring to move back and forth through the straight groove opened on the outside. When the driving ring moves, it will synchronously drive the erasing plate through the driving rod to erase the front-end monitoring device in the control element, thereby reducing the dust attached to the outside of the front-end monitoring device and the possibility of blurred monitoring.

[0024] (5) The front-end monitoring device inside the control element is used to monitor the windage angle, dancing condition and other data of the conductor in real time. It usually adopts high-precision sensors and advanced wireless communication technology to ensure the accuracy and real-time nature of the data. It uses wireless network technologies such as 3G / GPRS / CDMA or 4G to transmit the data collected by the front-end monitoring device to the monitoring center system in real time. This wireless transmission method is flexible and convenient and is not restricted by the geographical environment. The monitoring center system receives and processes the data transmitted by the front-end monitoring device and judges the windage condition through data analysis software. When an abnormal situation is found, the system will automatically issue an early warning message to provide It prompts managers to take corresponding preventive measures, conducts real-time monitoring of the wind deviation angle and dancing conditions of the transmission line, ensures the accuracy and timeliness of the data, processes and analyzes the collected data, and determines whether there is a wind deviation risk in the transmission line.

[0038] like Figure 2 , Figure 3 As shown, the extrusion mechanism includes a tooth block 10, which is fixedly connected to the lower surface of the movable column 3. The four side walls of the tooth block 10 all have external teeth, and a reset spring 9 is fixedly connected between the lower end of the tooth block 10 and the bottom of the fixed column 2. The upper end of the reset spring 9 is fixedly connected to the bottom of the tooth block 10, and the lower end of the reset spring 9 is fixedly connected to the bottom of the fixed column 2. The rotating rod 4 is arranged in four groups in a circular array about the center point of the fixed column 2, that is, the rotating rod 4 has four groups, and is distributed on the four sides of the fixed column 2. The tooth ring 15 arranged at the lower end of the rotating rod 4 is in a meshing assembly mode with the tooth block 10, and the rotating rod 4 is in a rotational connection relationship with the fixed column 2 through the tooth block 10. The rotation mode of the rotating rod 4 relative to the fixed column 2 is: the tooth ring 15 at the lower end of the rotating rod 4 meshes with the tooth block 10 and moves relative to each other to realize the rotation of the rotating rod 4.

[0039] like Figure 5 As shown, the auxiliary plate 5 has a movable groove 18, and the movable groove 18 is opened on the inner side of the auxiliary plate 5. Figure 6 As shown, a stabilizing rod 11 is nested and connected to the inner side of the movable groove 18, and the stabilizing rod 11 can move in the movable groove 18. An adjusting mechanism for driving the stabilizing rod 11 to rotate is provided between the inside of the movable groove 18 and the upper surface of the rotating rod 4.

[0040] like Figure 6 As shown, the adjustment mechanism includes a limiting groove 16, which is opened inside the auxiliary plate 5, and a limiting block 17 is nested and connected in the limiting groove 16. The limiting block 17 is essentially a rectangular metal block, and the inner side of the limiting block 17 is fixedly connected to the outer side of the stabilizing bar 11, as shown in FIG. Figure 5As shown, a threaded rod 14 is hinged at the center of the upper surface of the rotating rod 4, and the threaded rod 14 is threadedly connected to the inner side of the edge of one end of the stabilizing rod 11. That is, the edge of the stabilizing rod 11 is a circular ring structure, and the circular ring structure has an internal thread, and the threaded rod 14 passes through the edge of one end of the stabilizing rod 11 and is threadedly connected thereto.

[0041] like Figure 7 As shown, the four sides of the docking block 19 are provided with stabilizing grooves 20, and the other end of the stabilizing rod 11 is nested and connected inside the stabilizing groove 20, as shown in FIG.

[0042] The user can place the work box 6 initially by docking the docking block 19 with the mobile column 3.

[0043] When the auxiliary plate 5 contacts the lower side of the placement plate 13, the rotating rod 4 continues to rotate, which will drive the threaded rod 14 hinged thereto to move upward along the movable groove 18. At the same time, the threaded rod 14 will enter the interior of the stabilizing rod 11. The stabilizing rod 11 will rotate synchronously under the action of the threaded connection with the threaded rod 14. Since the limit block 17 will move in the limit groove 16 driven by the stabilizing rod 11, the outer end of the stabilizing rod 11 can be stably rotated and nested into the stabilizing groove 20 opened on the side of the docking block 19 at this time, thereby further limiting the docking block 19, improving the stability of the placement of the working box 6, reducing the use of bolts, and enabling the working box 6 to be quickly installed and disassembled.

The inner protrusion of the driving ring 22 is nested and connected inside the straight groove 25, and the inner protrusion of the driving ring 22 is slidably connected with the straight groove 25, and then the driving ring 22 is slidably connected with the driving roller 12, and the sliding direction is the axial direction of the driving roller 12. Fig. 9 As shown, the outer end of the driving ring 22 is fixedly connected to a driving rod 23. Figure 1 As shown, the outer surface of the working box 6 is provided with a transversely arranged moving groove 27, and the driving rod 23 is nested and connected to the outer side of the moving groove 27, and the driving rod 23 and the moving groove 27 slide relative to each other. Fig. 9 As shown, one end of the driving rod 23 is fixedly connected to the outer wall of the driving ring 22, and the other end of the driving rod 23 is fixedly connected to an erasing plate 24, which is used to perform dust erasing work.

[0046] like Figure 1 As shown, the outer surface of the working box 6 is provided with nesting grooves 26 on both sides, and the two nesting grooves 26 are symmetrically arranged up and down, and the edge of the erasing plate 24 is nested and connected inside the nesting grooves 26. That is, the erasing plate 24 has a slider structure that is slidably connected to the nesting grooves 26. The driving roller 12 and the working box 6 form a rotating structure, and the external wind force drives the fan to rotate. Driven by the fan 8, the driving roller 12 and the working box 6 rotate relatively. The driving ring 22 and the driving rod 23 are fixedly connected by welding, and the two form an integrated structure, and the driving rod 23 forms a sliding structure with the moving groove 27 through the driving ring 22.

[0047] like Fig.10 As shown, the straight groove 25 is opened along the outer surface of the driving roller 12 in an inclined manner, and there are two straight grooves 25. Figure 1 As shown, while the erasing plate 24 directly forms a sliding structure with the nesting groove 26 , the erasing plate 24 also forms a sliding structure with the driving roller 12 through the driving rod 23 and the driving ring 22 .

[0048] The working principle of the moving mechanism is described in detail below: the fan 8 is affected by the external wind force, and will drive the driving roller 12 to rotate synchronously. At this time, the driving roller 12 will drive the driving ring 22 to move back and forth through the straight groove 25 opened on the outside. When the driving ring 22 is moving, it will synchronously drive the erasing plate 24 through the driving rod 23 to erase and clean the detection screen of the front-end monitoring device in the control element 21, reduce the dust attached to the outside of the front-end monitoring device, and improve the monitoring accuracy of the front-end monitoring device. The cleaning of the detection screen of the front-end monitoring device does not require a separate power setting, and can be achieved by relying on natural wind power, which is convenient to use.

[0049] An evaluation method for a wind deviation detection and early warning system for a power transmission line tower system of the present invention comprises the following steps: S1. Installation of early warning system The fixing plate 1 is fixedly installed on the transmission line tower, and the fixing plate 1 is ensured to be in a horizontal plane; S2. Installation of working box The docking block 19 is docked with the movable column 3, so that the working box 6 falls under its own weight. At this time, the movable column 3 moves relative to the fixed column 2, and the rotating rod 4 rotates relative to the fixed column 2, thereby performing a preliminary installation of the working box 6; S3. Data Monitoring Start the control element inside the working box 6 to monitor the windage angle and dancing data of the conductor; S4. Data processing and uploading The data monitored in step S3 is compared and evaluated with the set threshold, and the monitored data is uploaded to the monitoring center system, and an alarm is issued when the monitored data exceeds the set threshold.

[0050] Furthermore, after the auxiliary plate 5 contacts the lower side of the placement plate 13, the rotating rod 4 continues to rotate to drive the threaded rod 14 hinged thereto to move upward along the movable groove 18, and at the same time, the threaded rod 14 enters into the stabilizing rod 11. The stabilizing rod 11 and the threaded rod 14 rotate synchronously under the action of the threaded connection, and the stabilizing rod 11 is limited inside the stabilizing groove 20, thereby limiting the docking block 19 and improving the stability of the placement of the working box 6.

[0051] The user of the present invention can preliminarily place the work box by docking the docking block and the moving column. After the work box is placed, the work box will drive the moving column to move down along the fixed column under the influence of its own gravity. At this time, the fixed column will push the gear block to move down synchronously. When the gear block moves down, it will synchronously drive the rotating rod to rotate through the gear ring meshed with it. At this time, the rotating rod can be synchronously rotated inwardly, and the auxiliary plate set on the upper side of the rotating rod will contact the lower side of the placement plate set at the lower end of the work box, thereby increasing the support range of the work box and improving the stability of the placement of the work box. After the auxiliary plate contacts the lower side of the placement plate, the continuous rotation of the rotating rod will drive the threaded rod hinged thereto to move up along the movable groove, and the threaded rod will enter the interior of the stabilizing rod. The stabilizing rod will rotate synchronously under the action of the threaded connection with the threaded rod, and be nested in the stabilizing groove, thereby further limiting the docking block, improving the stability of the placement of the work box, reducing the use of bolts, and allowing the work box to be quickly installed and disassembled. Because the limit block moves within the limit slot driven by the stabilizing rod, the outer end of the stabilizing rod can be stably rotated and nested into the stabilizing slot opened on the side of the docking block, further improving the stability of the stabilizing rod during rotation. The fan is affected by the external wind force, which will drive the driving roller to rotate synchronously. At this time, the driving roller will drive the driving ring to move back and forth through the straight groove opened on the outside. When the driving ring moves, it will synchronously drive the erasing plate through the driving rod to erase the front-end monitoring device in the control element, reducing the possibility of dust adhering to the outside of the front-end monitoring device, which may cause monitoring blur.

[0052] The front-end monitoring device inside the control element is used to monitor the windage angle, dancing condition and other data of the conductor in real time. It usually adopts high-precision sensors and advanced wireless communication technology to ensure the accuracy and real-time nature of the data. It uses wireless network technologies such as 3G / GPRS / CDMA or 4G to transmit the data collected by the front-end monitoring device to the monitoring center system in real time. This wireless transmission method is flexible and convenient and is not restricted by the geographical environment. The monitoring center system receives and processes the data transmitted by the front-end monitoring device, and judges the windage condition through data analysis software. When an abnormal situation is found, the system will automatically issue an early warning message to prompt Managers take corresponding preventive measures and conduct real-time monitoring of the wind deviation angle and dancing conditions of the transmission lines to ensure the accuracy and timeliness of the data. They process and analyze the collected data to determine whether there is a risk of wind deviation in the transmission lines. When abnormal conditions are found, the system will automatically issue early warning information, including sound and light alarms, SMS notifications and other methods to prompt managers to take timely measures. It supports remote control and management of front-end monitoring devices, including data collection, parameter setting, equipment status query and other functions. The collected data is stored in the database, and historical data query and export are supported to provide data support for subsequent analysis and research.
