Description

Technical Field

[0001] The invention relates to the field of lightning protection for power transmission lines, and in particular to an online monitoring device for lightning protection for power transmission lines. Background Art

[0002] Transmission lines are realized by using transformers to step up the voltage of the electric energy generated by generators, and then connecting them to transmission lines through control equipment such as circuit breakers. They usually include overhead transmission lines and cable lines. Overhead transmission lines usually refer to lines suspended in the air formed by connecting through poles, towers, etc. Since such circuits are directly exposed to the outside world, the impact of thunderstorms on the lines needs to be considered when they are erected. In the prior art, an additional layer of lightning protection wire is usually erected above the line to guide lightning, and the voltage of the lightning strike is conducted to the ground along the conductive wires on the poles, thereby preventing lightning from directly striking the transmission lines.

[0003] Although the lightning arrester used in the prior art can provide good lightning protection performance, it is necessary to lay the lightning arrester above the entire transmission line. The transmission line is long, so the lightning arrester needs to be laid on the entire transmission line, which greatly delays the installation efficiency of the entire transmission line. Moreover, laying the lightning arrester over a long distance will result in an overall high construction cost. In addition, since the lightning arrester needs to be installed above the transmission line, the use of the lightning arrester will also affect the design work of the entire transmission line. Summary of the invention

[0004] The present invention aims at the deficiencies in the prior art and provides the following technical solutions:

[0005] A transmission line lightning protection online monitoring device comprises: a shell, a lightning protection component arranged at the center of the shell, and a host computer.

[0006] Specifically, limit grooves are provided at both ends of the shell, and a connecting frame that can rotate in a circle is arranged inside the limit groove. A clamping claw assembly for grabbing the electric wires is fixed to the upper end of the connecting frame. The lightning protection assembly includes a conductive rope that can be reeled or unreeled. The host computer includes a GIS positioning system for positioning the shell. When a thunderstorm occurs, the connecting frames at both ends of the shell rotate, driving the clamping claw assemblies to alternately grab and fix the electric wires to form a rotary advance until they move to the position determined by the GIS positioning system, and unreel the conductive rope until the conductive rope touches the ground to form a grounding.

[0007] As an improvement of the above technical solution, a protrusion is formed on the inner side of the limiting groove, an inner cavity is opened inside the protrusion, a double-headed motor is arranged inside the inner cavity, the two power ends of the double-headed motor pass through the outside of the protrusion and are fixed to the shell, the two power ends of the double-headed motor pass through a connecting frame arranged inside the limiting groove, and the connecting frame is fixedly connected to the power ends of the double-headed motor.

[0008] As an improvement of the above technical solution, the connecting frame is U-shaped and has two branches. A sealing ring is arranged at the center position of the branch. The branch is inserted into the inside of the limiting groove. The sealing ring is embedded in the notches on both sides of the protruding part of the double-headed motor, and the power shaft of the double-headed motor passes through the sealing ring.

[0009] As an improvement of the above technical solution, the clamping claw assembly includes a limit plate, a telescopic rod, two support arms and two clamping arms, the power end of the telescopic rod is provided with a radially penetrating movable shaft 1, the two sides of the movable shaft 1 are penetrated and connected with support arms, the other end of the support arm is rotatably connected with the clamping arm through a penetrated movable shaft 2, the other end of the clamping arm is integrally formed with an arc claw, a positioning shaft is penetrated at the middle position of the clamping arm, the two ends of the positioning shaft penetrate into the interior of the limit plate, the telescopic rod is fixed between the two limit plates, the angle between the telescopic rod and the support arm is greater than 90°, the angle between the support arm and the clamping arm is less than 90°, the rotation direction of the power shaft of the double-headed motor is perpendicular to the rotation direction of the arc claw grasping the wire, when the telescopic rod is extended, the angle between the support arm and the telescopic rod is reduced, and the angle between the support arm and the clamping arm is increased to control the symmetrically arranged arc claws to grasp the wire.

[0010] As an improvement of the above technical solution, a penetrating inner groove is opened in the middle position of the shell, and a connecting shell penetrating up and down is fixed inside the inner groove. A driving motor is arranged on one side of the connecting shell, and the power end of the driving motor is connected to a roller penetrating the connecting shell. A winding roller is fixed on the outside of the roller, and the winding roller is located inside the connecting shell. A conductive rope is wound on the outside of the winding roller, and a counterweight block is fixed to the other end of the conductive rope.

[0011] As an improvement of the above technical solution, a lightning rod is integrally formed on the inner wall of the connecting shell. The lightning rods are at least two groups and are symmetrically arranged on the opening side of the connecting shell. The connecting shell includes a conductive part and an insulating part. The roller fits the inner wall of the conductive part, and the lightning rod is integrally formed with the inner wall of the conductive part.

[0012] As an improvement of the above technical solution, the shell is symmetrically divided into a bottom shell and a top shell along the center position, and the top shell and the bottom shell are fixed by a plurality of penetrating bolts.

[0013] As an improvement of the above technical solution, a camera module, a positioning module, a sensor module, a solar power supply module and a main control module are provided. The camera module is used to capture and save image information around the shell and the wires. The positioning module is used to communicate with the GIS positioning system and transmit the current position information of the shell. The sensor module is used to detect environmental data around the shell through sensors. The solar power supply module is used to power the positioning module, the sensor module, the drive motor and the double-headed motor. The main control module is used to control the positioning module, the sensor module, the solar power supply module, the drive motor and the double-headed motor to perform corresponding actions according to the commands sent by the host computer.

[0014] As an improvement of the above technical solution, the host computer includes a voltage detection module, an image recognition module, and a wireless module. The wireless module is used to communicate with the main control module and exchange data. The voltage detection module is used to detect the real-time parameters of the transmission line voltage. The image recognition module is used to identify the image information taken by the camera module and perform actions according to the image information.

[0015] As an improvement of the above technical solution, the camera module includes at least two cameras, which are embedded in the two ends of the shell along the direction of the wires. The sensor module includes a pressure sensor, which is arranged at one end of the telescopic rod away from the movable axis.

[0016] Beneficial effects of the present invention:

[0017] Through the active grasping and fixing by the provided claw assembly, the entire shell can be directly fixed on the wire through the claw assembly after the transmission line is completely laid, so as to position and fix the lightning protection assembly. This installation method is relatively convenient and does not require large-scale erection. It only needs to be installed after the transmission line is erected. In thunderstorms, the location with such weather can be located through the GIS positioning system, and the connecting frame can be controlled to rotate in advance and drive the entire shell to move to the corresponding weather. Due to the positioning function, it is only necessary to call the device near the thunderstorm weather. The overall moving distance will not be very far, and automatic gathering can be achieved relatively quickly. When the gathered devices reach a certain number, the lightning protection function within the range can be achieved through the lightning protection assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Although the lightning arrester used in the prior art can provide good lightning protection performance, it is necessary to lay the lightning arrester above the entire transmission line. The transmission line is long, so the lightning arrester needs to be laid on the entire transmission line, which greatly delays the installation efficiency of the entire transmission line. Moreover, laying the lightning arrester over a long distance will result in an overall high construction cost. In addition, since the lightning arrester needs to be installed above the transmission line, the use of the lightning arrester will also affect the design work of the entire transmission line.

[0032] To solve the above problems, see Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10 , provides an online monitoring device for lightning protection of a power transmission line, comprising: a shell 10, a lightning protection component 20 arranged at the center of the shell 10, and a host computer 30.

[0033] Specifically, limit grooves 11 are provided at both ends of the shell 10, and a connecting frame 13 that can rotate in a circle is arranged inside the limit groove 11. A clamping claw assembly 14 for grabbing the wires is fixed to the upper end of the connecting frame 13. The lightning protection assembly 20 includes a conductive rope 23 that can be reeled or unreeled. The upper computer 30 includes a GIS positioning system 32 for positioning the shell 10. When a thunderstorm occurs, the connecting frames 13 at both ends of the shell 10 rotate, driving the clamping claw assembly 14 to alternately grab and fix the wires to form a rotary advance until it moves to the position determined by the GIS positioning system 32, and unwinds the conductive rope 23 until the conductive rope 23 touches the ground to form a grounding.

[0034] GIS weather monitoring is performed near the transmission line through the GIS positioning system 32. When thunderstorms or other weather conditions that may cause thunder are found, the transmission lines within the area are located, and all devices within the area are controlled to move. The clamping jaw assembly 14 connected to the wire is switched by rotating the connecting frame 13. In this way, one clamping jaw assembly 14 is fixed to the wire each time, and continuously moves in the direction of rotation during the alternating switching process, thereby forming a moving function. The advantage of this driving method is that the junction of conventional electric poles will be blocked by structures such as frames and connectors, and ordinary wheeled connection structures cannot bypass this structure. The installation structure of the lightning protection assembly 20 disclosed in this embodiment can avoid the problem that the wheeled structure cannot move.

[0035] In addition, the scheme recorded in this embodiment needs to ensure that the path of the line is on a vertical plane. If a turning point appears, it may not be possible to move at the turning point. For example, if there is a mountain in a certain area, the transmission line may be installed to bypass the mountain. In this case, there is a certain angle at the turning point, and it is impossible to move at the turning point.

[0036] In one embodiment, see Figure 1 , Figure 5 , Figure 6 and Figure 7 Specifically, a protrusion 12 is formed on the inner side of the limiting groove 11, an inner cavity 122 is opened inside the protrusion 12, a double-headed motor 133 is arranged inside the inner cavity 122, and two power ends of the double-headed motor 133 pass through the outer side of the protrusion 12 and are fixed to the shell 10, and the two power ends of the double-headed motor 133 pass through the connecting frame 13 arranged inside the limiting groove 11, and the connecting frame 13 is fixedly connected to the power end of the double-headed motor 133.

[0037] In this embodiment, if the entire shell 10 is controlled to move along the wire, it is necessary to ensure that the clamping jaw assembly 14 on one side is fixed, while the clamping jaw assembly 14 on the other side is loosened, and a double-headed motor 133 is used internally for control. In this way, the rotation function of the connecting frame 13 can be guaranteed, so that the purpose of moving the entire device can be achieved by alternatingly switching the clamping mode of the wire.

[0038] In order to further ensure that the clamping jaw assembly 14 can stably follow the adjustment when the housing 10 rotates and switches directions, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 Specifically, the connecting frame 13 is U-shaped and has two branches 131. A sealing ring 132 is provided at the center of the branch 131. The branch 131 is inserted into the limiting groove 11. The sealing ring 132 is embedded in the grooves on both sides of the protrusion 12 of the double-headed motor 133. The power shaft of the double-headed motor 133 passes through the sealing ring 132.

[0039] In the above scheme, when it is necessary to control the movement of the shell 10, first release the clamping jaw assembly 14 away from the moving side, and control the double-headed motor 133 on the other side to rotate, driving the entire shell 10 to rotate. During the rotation process, the direction of the shell 10 is immutable. Since the fixation of the double-headed motor 133 itself depends on the connecting frame 13, when the double-headed motor 133 loses its fixation, and the shell 10 itself is fixed to the double-headed motor 133 on the other side, and the double-headed motor 133 on the other side is itself fixed on the wire, if the double-headed motor 133 on one side of the released clamping jaw assembly 14 rotates synchronously at this time, it will drive the entire connecting frame 13 to rotate. Therefore, in the process of adjusting the shell 10, the two double-headed motors 133 rotate at the same time, so that it can be ensured that in the process of turning the shell 10, the released clamping jaw assembly 14 adjusts the angle synchronously. When the shell 10 completes the adjustment, the clamping jaw assembly 14 also grabs the wire. The specific state changes are as follows Fig.11 As shown, Fig.11 a is the initial state, Fig.11 b is the state where the clamping jaw assembly 14 at one end is loosened, Fig.11 c is the state when the housing 10 rotates to the other side. At this time, the conductive rope 23 is unwound for more than half a circle due to the rotation. Therefore, in the subsequent process, the conductive rope 23 needs to be rewound. Fig.11 d is the state after the housing 10 is turned over once.

[0040] In addition, the sealing ring 132 is used to block the end of the double-headed motor 133, thereby preventing rainwater from easily entering the interior. Since there are gaps between the structural parts, the interior will not be completely closed. A small amount of rainwater that enters the interior will be evaporated or dried by the wind on sunny or windy days, and will not affect the normal use of the double-headed motor 133.

[0041] In one embodiment, in order to further improve the specific scheme of the clamping jaw assembly 14 in this embodiment, please refer to Figures 1 to 7 as well as Fig.11 , specifically:

[0042] The clamping jaw assembly 14 includes a limit plate 141, a telescopic rod 142, two support arms 144 and two clamping arms 146. The power end of the telescopic rod 142 is provided with a radially penetrating movable shaft 143, and the two sides of the movable shaft 143 are connected with the support arms 144. The other end of the support arm 144 is rotatably connected with the clamping arm 146 through the penetrating movable shaft 2 145. The other end of the clamping arm 146 is integrally formed with an arc-shaped claw 148. The middle position of the clamping arm 146 is penetrated by a positioning The shaft 147 and the two ends of the positioning shaft 147 penetrate into the interior of the limiting plate 141, and the telescopic rod 142 is fixed between the two limiting plates 141. The angle between the telescopic rod 142 and the support arm 144 is greater than 90°, and the angle between the support arm 144 and the clamping arm 146 is less than 90°. When the telescopic rod 142 is extended, the angle between the support arm 144 and the telescopic rod 142 is reduced, and the angle between the support arm 144 and the clamping arm 146 is increased to control the symmetrically arranged arc claws 148 to grasp the wires.

[0043] By extending the telescopic rod 142, the support arm 144 and the clamping arm 146 are pushed to realize the opening and closing of the arc-shaped claw 148 at the end, thereby realizing the clamping and releasing of the wire. In this scheme, it is necessary to ensure that the turning direction of the clamping jaw assembly 14 and the turning direction of the shell 10 do not affect each other. Therefore, when designing the structure, it is necessary to ensure that the rotation direction of the power shaft of the double-headed motor 133 is perpendicular to the rotation direction of the arc-shaped claw 148 to grasp the wire. In this way, when rotating, due to the inconsistent axial direction of rotation, in this case, the rotation of the two will not affect each other, thereby ensuring the stability of the clamping jaw assembly 14 and the shell 10 during the adjustment process.

[0044] In the above solution, the conductive rope 23 will swing due to its own gravity during the rotation of the housing 10. To prevent the conductive rope 23 from being entangled due to the swing, please refer to Figures 1 to 9 An inner groove 103 is provided in the middle of the shell 10, and a connecting shell 21 is fixed inside the inner groove 103 and passes through the shell 21 from top to bottom. A driving motor 24 is provided on one side of the connecting shell 21, and a power end of the driving motor 24 is connected to a roller 22 passing through the connecting shell 21. A reel 241 is fixed to the outside of the roller 22, and the reel 241 is located inside the connecting shell 21. A conductive rope 23 is wound on the outside of the reel 241, and a counterweight block 231 is fixed to the other end of the conductive rope 23.

[0045] The conductive rope 23 is wound by driving the motor 24, and a counterweight 231 is added to the tail of the conductive rope 23. The counterweight 231 ensures that the conductive rope 23 is in a normal straight state. When the housing 10 is turning, Fig.11 b and Fig.11 As shown in the state in c, the setting of the counterweight block 231 unwinds the conductive rope 23 by half a circle. In this case, the conductive rope 23 can be rewound by driving the motor 24.

[0046] To further enhance the overall structure's attraction to lightning, see Figure 1 and Figure 2 The inner wall of the connecting shell 21 is integrally formed with a lightning rod 25. There are at least two groups of lightning rods 25, which are symmetrically arranged on the opening side of the connecting shell 21. The connecting shell 21 includes a conductive part 211 and an insulating part 212. The roller 241 is attached to the inner wall of the conductive part 211, and the lightning rod 25 is integrally formed with the inner wall of the conductive part 211.

[0047] The lightning rod 25 attracts the lightning, and the voltage of the lightning strike is conducted to the conductive rope 23 along the conductive part 211. When it moves to the positioned position, the unwound conductive rope 23 transfers the voltage to the ground, thereby forming a grounded state to avoid electric shock to the transmission line and causing failure of the transmission line.

[0048] To ensure the disassembly of the structure, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The housing 10 is symmetrically divided into a bottom housing 101 and a top housing 102 along the center position, and the top housing 102 and the bottom housing 101 are fixed by a plurality of penetrating bolts.

[0049] Splitting into two symmetrical parts (i.e., the bottom shell 101 and the top shell 102) can ensure that the subsequent disassembly of the internal structure is more convenient, especially after long-term use, the interior needs to be cleaned to prevent the double-headed motor 133, the conductive rope 23 and other structures from being covered with dust, resulting in the structure being unable to be used normally.

[0050] In addition to the contents described in the above embodiments, please refer to Fig.10 , and also includes the following solutions:

[0051] Camera module 121 , positioning module 15 , sensor module 16 , solar power supply module 17 and main control module 18 .

[0052] The camera module 121 is used to capture and save image information of the shell 10 and the surrounding of the wires. The positioning module 15 is used to communicate with the GIS positioning system 32 and transmit the current position information of the shell 10. The sensor module 16 is used to detect environmental data around the shell 10 through sensors. The solar power supply module 17 is used to power the positioning module 15, the sensor module 16, the drive motor 24 and the double-headed motor 133. The main control module 18 is used to control the positioning module 15, the sensor module 16, the solar power supply module 17, the drive motor 24 and the double-headed motor 133 to perform corresponding actions according to the commands sent by the host computer 30.

[0053] The camera module 121 is usually installed on the outside of the shell 10. The surrounding environment is photographed by the camera module 121. This is an emergency plan to deal with errors in meteorological monitoring. The image taken by the camera module 121 will be transmitted to the host computer 30 for analysis. If it is judged that a lightning strike is likely to occur, the mobilization work is also performed to gather the devices around the judged area into the area, thereby realizing protection against lightning strikes.

[0054] The main function of the positioning module 15 is to locate its own installation position, that is, to determine the position of each shell 10 by positioning the positioning module 15. It is usually installed inside the shell 10. When the device needs to be called, the positioning module 15 can accurately display the position of the device in and near the area that needs to be called, thereby meeting the prerequisite work for active and automatic calling.

[0055] The sensor module 16 usually includes a lightning sensor, a humidity sensor, etc. The lightning sensor is mainly used to detect the specific lightning rod 25 that is struck by lightning, so that the location of the lightning strike can be confirmed. In subsequent maintenance work, the location of the lightning strike can be accurately located. The purpose of the humidity sensor is to actively detect. When there is abnormal humidity in the area, it is judged that it may be a rainy day. At this time, the GIS meteorological information of the humidity abnormal area can be located according to the GIS positioning system 32, and a comprehensive judgment can be made as to whether a lightning strike will occur.

[0056] The solar power supply module 17 is usually installed on the side facing the sun, and uses sunlight to ensure that there is enough power to drive. It usually adopts the cooperation between solar photovoltaic panels and energy storage batteries, performs photoelectric conversion through solar photovoltaic panels, and stores the converted electrical energy through energy storage batteries.

[0057] In one embodiment, see Fig.10The host computer 30 includes a voltage detection module 31, an image recognition module 33, and a wireless module 34. The wireless module 34 is used to communicate with the main control module 18 and exchange data. The voltage detection module 31 is used to detect the real-time parameters of the transmission line voltage. The image recognition module 33 is used to identify the image information taken by the camera module 121 and perform actions according to the image information.

[0058] The voltage detection module 31 refers to a detector connected to the transmission line, which is used to determine whether there is an abnormal voltage in the transmission line. This module is used to perform auxiliary detection on the transmission line to avoid the problem of erroneous judgment caused by failure of a single detection device.

[0059] The image recognition module 33 is a module used to recognize the image data sent by the camera module 121. By recognizing the image data of the surrounding environment, it can intuitively determine whether it is a thunderstorm day and determine whether it is necessary to mobilize nearby devices for lightning protection.

[0060] The wireless module 34 is used to actively communicate and interact with the main control module 18, to receive relevant data sent by the main control module 18 and to send relevant control commands to the main control module 18, and to control the lower positioning module 15, sensor module 16, solar power supply module 17, drive motor 24 and double-head motor 133 through the main control module 18 to perform corresponding actions.

[0061] In one embodiment, see Figures 1 to 4 The camera module 121 includes at least two cameras, which are embedded in the two ends of the shell 10 along the direction of the wires. The sensor module 16 includes a pressure sensor 161, which is arranged at one end of the telescopic rod 142 away from the movable axis 143.

[0062] The two cameras are used to monitor the environmental information around the entire housing 10 , and the cameras can also monitor the wires and determine whether there is a fault in the wires through the image recognition module 33 .

[0063] The pressure sensor 161 is provided to adjust the control state of the telescopic rod 142. During the adjustment process, the telescopic rod 142 can be started, stopped and extended only by impact. When the main control module 18 receives the command to control the contraction of the telescopic rod 142 and takes action, the telescopic rod 142 is completely contracted. Fig.11As shown in the state of c, if the shell 10 continues to turn, the telescopic rod 142 will hit the wire. Since the pressure sensor 161 is at the end of the telescopic rod 142, the pressure sensor 161 will be hit. At this time, it is synchronously determined to start the extension command, thereby completing the clamping state. In this embodiment, only a contraction command needs to be sent to the main control module 18 instead of an extension command, which reduces the overall interaction at this time, thereby having faster work efficiency.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
