Description

Technical Field

[0001] The present invention relates to the field of transmission line temperature detection, and in particular to a method for installing a transmission line line clamp temperature sensor. Background Art

[0002] In the industry, when using wire clamp temperature sensors to measure the temperature of transmission lines, there are two situations: live installation and power-off installation.

[0003] During power outage installation, the power supply to the transmission line where the installation point is located needs to be shut down. Workers working at height need to climb to the installation location to install it. However, due to the limitations of the installation structure and installation method, workers can only install the wire clamp temperature sensor on the tension wire clamp drainage plate. For other monitoring points prone to heat, such as the crimping points of hydraulic tension wires and conductor joints, it is difficult to install them while ensuring the safety of workers. As a result, the monitoring position of the wire clamp temperature sensor is relatively single. In addition, during the installation process, workers working at height need to first remove the original bolts of the tension wire clamp drainage plate, install the temperature sensor mounting plate to the designated position, and then re-tighten it. This destroys the original hardware connection and is prone to safety hazards and disputes.

[0004] During live installation, workers working at height must wear insulating clothing and climb to the edge of the tower near the tension clamp. During this process, they must hold a telescopic insulating rod with a live installation tool equipped with a wire clamp temperature sensor at the end. Using the rod, they attach the wire clamp temperature sensor to the tension clamp, completing the installation. Limited by the worker's climbing height and the length of the insulating rod, the installation location of the wire temperature sensor is also limited. Furthermore, live workers face the risk of electric shock if their insulating clothing is damaged or inadequately shielded.

[0005] Therefore, a new installation method of the wire clamp temperature sensor is urgently needed to solve the above technical problems. Summary of the Invention

[0006] In order to solve the above technical problems, the present application provides a method for installing a transmission line clamp temperature sensor.

[0007] This application provides a method for installing a temperature sensor on a transmission line clamp, which adopts the following technical solution: A method for installing a wire clamp temperature sensor for a power transmission line, the method involving the wire clamp temperature sensor and a tool for installing the wire clamp temperature sensor. The upper end of the wire clamp temperature sensor is provided with two clamps for clamping the power transmission line. The two clamps have an open posture when an external force is applied and a clamped posture in a natural state. The open posture is a state to be installed, and the clamped posture is a detection state. The installation tool includes a drone and a mounting structure arranged above the drone, the mounting structure is made of insulating material and is used to restrain the clamps so that the two clamps remain in an open position when only gravity acts on them; The installation method of the wire clamp temperature sensor includes the following steps: S1. Install the clamp on the wire clamp temperature sensor on the top of the mounting structure in an open position; S2. Use a drone to lift the wire clamp temperature sensor to the position directly below the transmission line to be tested, and adjust the position of the drone so that the transmission line is in the middle of the clamp in the open position; S3. After adjusting the position of the drone, use the drone to drive the wire clamp temperature sensor to rise until the upper end of the wire clamp temperature sensor contacts the transmission line; S4. Use drone technology to drive the wire clamp temperature sensor to rise, and under the obstruction of the power line, until the clamp is separated from the installation structure and holds the power line tightly; S5. Use the drone to move the installation structure downward, and the wire clamp temperature sensor stays at the position to be tested on the transmission line and performs contact temperature detection.

[0008] By adopting the above technical solution, the drone limits the clamp through the mounting structure, so that when the drone drives the wire clamp temperature sensor to lift through the mounting structure, the mounting structure keeps the clamp in an open position. When the activity space meets the working requirements of the drone, the drone can lift the wire clamp temperature sensor to any position on the power transmission line, expanding the detection range. Through the cooperation of the two clamps, the wire clamp temperature sensor can be clamped to the power transmission line and measure the temperature of the power transmission line after being detached from the mounting structure. The temperature measurement process is convenient and does not require high-altitude workers to climb high to operate. The installation process of the wire clamp temperature sensor can be carried out with or without power on the power transmission line. The installation process is relatively simple and does not require workers to come into contact with the power transmission line during the installation process, which has high installation safety.

[0009] Optionally, in S1, the wire clamp temperature sensor includes a bracket for connecting a clamp, the bracket is fixed to the upper end of the wire clamp temperature sensor, the two clamps are respectively located at the two ends of the bracket in the horizontal direction, and are hinged to the bracket in the vertical direction, and a first clamping groove is provided on the side where the two clamps are close to each other, and a second clamping groove is provided on the upper end of the bracket. When the two clamps clamp the power transmission line, the power transmission line is located in the first clamping groove and the second clamping groove, and an elastic member 1 is provided between the clamp and the bracket. When the elastic member 1 is in a natural state, the two clamps are close to each other and in a clamping posture.

[0010] By adopting the above technical solution, the wire clamp temperature sensor limits the two clamps through the bracket, so that the moving trajectories of the two clamps are in the same plane. When the two clamps approach each other and clamp the power transmission line under the action of the elastic member 1, the first clamping groove and the second clamping groove both limit the power transmission line, thereby improving the clamping stability of the power transmission line.

[0011] Optionally, in S1, the mounting structure includes a limit frame, an elastic member 2 and two mounting rods. The limit frame is fixed above the drone, and the two mounting rods are fixed above the limit frame, and the two mounting rods are inclined from bottom to top in a direction away from each other. The elastic member 2 is located between the two mounting rods, and a limit plate is provided on the side where the two mounting rods are close to each other. The lower end of the limit plate is provided with a limit groove for limiting the clamp. When the wire clamp temperature sensor is installed, the wire clamp temperature sensor is above the elastic member 2 and the elastic member 2 is in a deformed state. All the limit plates cooperate to make the clamp in an open posture. At this time, the elastic member 2 has space to continue to deform.

[0012] By adopting the above technical solution, the drone drives the installation rods via the limit frame. When installing the wire clamp temperature sensor, the wire clamp temperature sensor is placed between the two installation rods. At this time, the elastic member 2 is compressed by the wire clamp temperature sensor and is in a deformed state. The limit plate limits the clamp in the open position through the limit groove. When installing the wire clamp temperature sensor, the drone is used to make the upper end of the wire clamp temperature sensor contact the power line. The drone is lifted. Under the obstruction of the power line, the wire clamp temperature sensor continues to compress the elastic member 2. During this process, the clamp gradually moves out of the limit groove. After the clamp is released from the slot, it is clamped to the power line by the action of the elastic member 1.

[0013] Optionally, the mounting structure further includes a guide rod, which corresponds one-to-one to the mounting rod and is fixed to one end of the corresponding mounting rod away from the limit frame. The guide rod extends along the mounting rod in a direction away from the limit frame, and the outer side of the guide rod is coated with a color-developing layer, which is used to improve the recognition of the guide rod in an outdoor background.

[0014] By adopting the above technical solution, when adjusting the position of the drone, the guide rod can easily guide the power transmission line to move between the two clamps, and the color-developing layer is conducive to improving the recognition of the guide rod, making it easier for operators to identify it.

[0015] Optionally, a guide wire is provided between the guide rod and the limiting plate, one end of the guide wire is connected to the end of the guide rod away from the mounting rod, and the other end is connected to the end of the limiting plate away from the mounting plate.

[0016] By adopting the above technical solution, when the drone drives the guide rod close to the transmission line, the transmission line first contacts the guiding wire. At this time, the guiding wire is used to guide the transmission line to slide between the two clamps, which is beneficial to reducing the probability of the transmission line colliding with the limiting plate and improving the guiding effect of the guide rod.

[0017] Optionally, two groups of projection light bars are provided on the limiting frame. The two groups of projection light bars are parallel to each other. When the projection light bars work, they project light. When the clamp temperature sensor is installed on the installation structure, it is located between the two groups of projection light bars. The limiting frame is provided with an adjusting plate for installing the projection light bars. When the adjusting plate is only affected by gravity, the light projected by the projection light bars is vertically upward. A camera for observing the state of the installation structure is fixedly installed above the drone.

[0018] By adopting the above technical solution, during the installation process, the drone is always below the transmission line. Under the action of the adjusting plate, the two groups of projection light bars are both vertically upward and project light on the lower end face of the transmission line. The installation position of the clamp temperature sensor is located between the two light rays. The operator observes the position of the light rays through the camera, thereby facilitating further alignment of the installation position of the clamp temperature sensor and being beneficial to improving the installation accuracy of the clamp temperature sensor.

[0019] Optionally, the limiting groove extends to the end face of the limiting plate away from the mounting rod. Two stoppers are slidably connected to the end of the limiting plate away from the mounting rod in the transverse direction. An elastic member III is provided between the stoppers and the limiting plate. In the natural state of the elastic member III, the two stoppers approach each other and block the end of the limiting groove away from the mounting rod. A guiding surface is provided at one end of the stopper away from the mounting rod. When the clamp approaches the mounting rod along the guiding surface, the two stoppers are pushed away from each other through the guiding surface.

[0020] By adopting the above technical solution, in the initial state, the two stoppers approach each other under the action of the elastic member III. When placing the clamp temperature sensor on the installation structure, the clamp is rotated towards the limiting plate. After the clamp contacts the guiding surface, it presses the stopper, causing the two stoppers to move away from each other under the action of the pressure. When the clamp enters the limiting groove, the stopper resets under the action of the elastic member III. At this time, the two stoppers cooperate to limit the clamp, which is beneficial to improving the convenience when installing the clamp temperature sensor.

[0021] Optionally, the clamp temperature sensor includes a bracket for connecting the fixture. The bracket is fixed to the upper end of the clamp temperature sensor. Both fixtures are hinged to the upper end of the bracket, and the two fixtures are arranged in mirror opposition. The bracket is provided with a first elastic member for pushing the two fixtures closer. Both fixtures are fixedly connected with a rotating rod coaxial with their hinge axis. The rotating rod passes through the bracket and is rotatably connected to the bracket. On both sides of the bracket in the width direction, there are vertically hinged abutting rods. The moving plane of the abutting rods is perpendicular to the moving plane of the fixtures. The abutting rods are fixedly connected with a connecting rod coaxial with their hinge axis. There is a bevel gear set connected between the connecting rod and the rotating rod. When the rotating rod rotates, it drives the connecting rod to rotate through the bevel gear set. When the two fixtures are in the clamping posture, all the abutting rods are in the horizontal state. When the end of the abutting rod away from the bracket rotates upward, the two fixtures gradually move away. On both sides of the limiting frame in the width direction, there are retractable ejector rods. When the clamp temperature sensor contacts the second elastic member, the ejector rods in the working state are directly opposite to the lower end surfaces of the horizontally placed abutting rods.

[0022] By adopting the above technical solution, when installing the clamp temperature sensor on the installation mechanism, the abutting rods are in a position close to the limiting frame, and the fixtures approach each other under the action of the first elastic member after separating from the limiting plate. When the fixtures rotate, they drive the rotating rods to rotate, so that the rotating rods drive the connecting rods to rotate through the bevel gear set. When the fixtures clamp the transmission line, the abutting rods are in the horizontal state, and at this time the ejector rods are in the retracted state. When it is necessary to disassemble the clamp temperature sensor, the operator adjusts the ejector rods to the working state. At this time, the installation structure is lifted by the unmanned aerial vehicle. When the clamp temperature sensor in the clamping posture contacts the second elastic member, the ejector rods are located below the corresponding abutting rods. Control the unmanned aerial vehicle to continue to lift. Under the limiting action of the transmission line, the ejector rods push the abutting rods to rotate upward, so that the connecting rods drive the rotating rods to rotate through the bevel gear set, and the rotating rods drive the fixtures to approach the limiting plate. When the fixtures push open the stoppers and enter the limiting grooves, they are in the open posture, thus completing the disassembly of the clamp temperature sensor, further improving the detection convenience.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. Installers do not need to work at high altitudes, ensuring the safety of the operators. 2. It can be installed in both live and de-energized states of the line, and the installation plan is not affected by the power company's power outage plan. 3. The installation positions are diverse, and it can be installed at positions where it is restricted for high-altitude operators to install, such as wire connecting sleeves and strain clamps, and the overall monitoring of potential trouble spots on the line can be realized. 4. The installation steps are simple, reducing the waste of installation man-hours, not requiring to change the connection state of the original fittings, and reducing the occurrence of potential safety hazards and disputes.

Detailed implementation manners

[0031] The following further elaborates on the present application in conjunction with all the attached drawings.

[0032] The embodiment of the present application discloses an installation method for a line clamp temperature sensor of a transmission line.

[0033] Embodiment 1: Referring to Figure 1 and Figure 2 , an installation method for a line clamp temperature sensor of a transmission line, in which the installation method involves a line clamp temperature sensor 1 and an installation tooling for the line clamp temperature sensor 1. Two fixtures 11 for clamping the transmission line are provided at the upper end of the line clamp temperature sensor 1. A bracket 12 for installing the fixture 11 is provided at the upper end of the line clamp temperature sensor 1. When the line clamp temperature sensor 1 is in a vertical state, the bracket 12 is in a horizontal state. Installation grooves are vertically provided at both ends of the bracket 12 along the length direction. The lower end of the fixture 11 is located in the installation groove and is vertically hinged to the bracket 12. The two fixtures 11 are arranged in a mirror-image opposition, and the two fixtures 11 approach or move away from each other when rotating.

[0034] An elastic member 13 is provided between the bracket 12 and the clamp 11. The elastic member 13 is a torsion spring. One end of the torsion spring is fixedly connected to the clamp 11, and the other end is fixedly connected to the bracket 12. In the natural state, the elastic member 13 drives the two clamps 11 to approach each other, and at this time, the clamps 11 are in a tightened posture. Only the first tightening groove 111 is provided on one side where the two clamps 11 approach each other, and the second tightening groove 121 is provided at the upper end of the bracket 12. When the two clamps 11 cooperate to clamp the transmission line, the transmission line is located in the first tightening groove 111 and the second tightening groove 121. The first tightening groove 111 and the second tightening groove 121 are beneficial to improving the tightening stability of the transmission line. The tightened posture of the clamp 11 is the detection state of the clamp temperature sensor 1; when an operator applies an external force to the clamp 11 to separate the two clamps 11 from each other, the clamp 11 is in an open posture, and the open posture is the state to be installed.

[0035] The installation method of the clamp temperature sensor 1 includes the following steps: S1. Install the clamp 11 on the line clamp temperature sensor 1 in an open posture at the top of the installation structure; S2. Use the drone 2 to lift the line clamp temperature sensor 1 directly below the position of the transmission line to be detected, and adjust the position of the drone 2 so that the transmission line is in the middle of the clamp 11 in the open posture; S3. After adjusting the position of the drone 2, use the drone 2 to drive the line clamp temperature sensor 1 to lift until the upper end of the line clamp temperature sensor 1 contacts the transmission line; S4. Use the drone 2 technology to drive the line clamp temperature sensor 1 to lift. Under the blocking action of the transmission line, until the clamp 11 disengages from the installation structure and clamps the transmission line; S5. Use the drone 2 to drive the installation structure to move down, and the line clamp temperature sensor 1 stays at the position of the transmission line to be detected and performs contact temperature detection.

[0036] In step S1, the installation tooling includes the drone 2 and an installation structure arranged above the drone 2. The installation structure includes a limit frame 31, an elastic member 32 and two installation rods 33. The limit frame 31 is located at the upper end of the drone 2, and the limit frame 31 is made of insulating material. The limit frame 31 includes a connecting frame 311, a vertical rod 312 and a placement frame 313. The connecting frame 311 is fixedly connected to the drone 2, and the vertical rod 312 is fixedly connected to the upper end of the connecting frame 311 in the vertical direction. When the drone 2 works, it drives the vertical rod 312 to move through the connecting frame 311.

[0037] The placement rack 313 is fixedly connected to the upper end of the vertical rod 312 and is provided with a chamber adapted for the wire clamp temperature sensor 1. The second elastic member 32 is a spring located within the chamber and fixedly connected to the placement rack 313. The spring is arranged along the length of the vertical rod 312. When an operator places the wire clamp temperature sensor 1 into the chamber, the wire clamp temperature sensor 1 compresses the second elastic member 32, causing it to deform.

[0038] The two mounting rods 33 are respectively located on both sides of the placement rack 313, and are tilted from bottom to top in a direction away from each other. The sides of the two mounting rods 33 that are close to each other are fixedly connected to a limiting plate 34. The limiting plate 34 is located above the placement rack 313, and the lower end surface of the limiting plate 34 is provided with a limiting groove 341 that is adapted to the clamp 11.

[0039] When installing the wire clamp temperature sensor 1 on the mounting frame, the operator adjusts the clamp 11 to an open position and inserts the clamp 11 into the limiting slot 341. At this time, the limiting plate 34 limits the clamp 11 through the limiting slot 341, and the clamp 11 remains in a tensioned state. The placement frame 313 supports the wire clamp temperature sensor 1 through the elastic member 2 32, thereby preventing the clamp 11 from escaping from the limiting slot 341. When the drone 2 drives the wire clamp temperature sensor 1 to rise, after the bracket 12 contacts the power line, the power line blocks the wire clamp temperature sensor 1 from further rising. When the drone 2 continues to rise, the wire clamp temperature sensor 1 is pushed by the drone 2 to squeeze the elastic member 2 32. At this time, the clamp 11 gradually detaches from the limiting slot 341. After the clamp 11 separates from the limiting plate 34, the elastic member 1 13 acts to hold the power line tightly.

[0040] In step S3, to facilitate adjustment of the position of the drone 2, a guide rod 35 is fixedly connected to the upper end of the mounting rod 33. The guide rod 35 extends away from the placement rack 313. When installing the wire clamp temperature sensor 1, the operator uses the guide rod 35 as a reference to manipulate the drone 2 until the power line is positioned between the two guide rods 35. The operator then adjusts the position of the drone 2 again, ultimately positioning the power line between the two clamps 11. The guide rod 35 is coated with a color-developing layer in a color easily recognized by the operator, such as red or bright yellow, which helps improve the recognition of the guide rod 35.

[0041] Example 2: Reference Figure 3, The difference between this embodiment and Embodiment 1 lies in the different structure of the guide rod 35. In this embodiment, a guiding wire 36 is arranged between the guide rod 35 and the limiting plate 34. One end of the guiding wire 36 is fixedly connected to the end of the guide rod 35 far from the mounting rod 33, and the other end is fixedly connected to the end of the limiting plate 34 far from the mounting rod 33. After the power transmission line enters between the two guide rods 35, if the guide rod 35 approaches the power transmission line, the guiding wire 36 will first come into contact with the power transmission line. At this time, the guiding wire 36 guides the power transmission line to slide between the two clamps 11. The guiding wire 36 is beneficial to guiding the power transmission line to cross over the limiting plate 34, thereby reducing the probability of the power transmission line colliding with the limiting plate 34 and improving the usability of the guide rod 35.

[0042] Embodiment 3: Referring to Figure 4 , The difference between this embodiment and Embodiment 1 lies in the different composition of the mounting structure. In this embodiment, projection lamp strips 37 are arranged on both sides of the placing rack 313 in the width direction. The placing rack 313 is vertically hinged with an orientation-adjusting plate 371, and the projection lamp strips 37 are installed above the orientation-adjusting plate 371. When the orientation-adjusting plate 371 is only affected by gravity, the projection lamp strips 37 are located at the upper end of the orientation-adjusting plate 371 and are arranged vertically upward. When the clamp temperature sensor 1 enters the chamber of the placing rack 313, it is between the two projection lamp strips 37.

[0043] When the projection lamp strips 37 work, they project light. When installing the clamp temperature sensor 1, the projection lamp strips 37 are always below the power transmission line, and the light projected by the projection lamp strips 37 shines below the power transmission line. A camera 21 is installed above the unmanned aerial vehicle 2. The operator observes the projection position of the light of the projection lamp strips 37 on the power transmission line through the camera 21. The projection range between the two lights is the installation position of the clamp temperature sensor 1, which is convenient for the operator to refer to and improves the accuracy of the installation position of the clamp temperature sensor 1.

[0044] Embodiment 4: Referring to Figure 5 and Figure 6 , The difference between this embodiment and Embodiment 1 lies in the different composition of the mounting structure: In this embodiment, the limiting groove 341 on the limiting plate 34 extends to the end face of the limiting plate 34 far from the mounting rod 33. Two stoppers 342 are arranged at the end of the limiting plate 34 far from the mounting rod 33. The two stoppers 342 are arranged horizontally and are slidably connected to the limiting plate 34 in a direction of approaching or separating from each other.

[0045] An elastic member 343 is provided between the stopper 342 and the limiting plate 34. The elastic member 343 is a spring. One end of the spring is fixedly connected to the stopper 342, and the other end is fixedly connected to the limiting plate 34. When the elastic member 343 is in a natural state, the two stoppers 342 are close to and abut against each other. A guide surface 344 is provided at one end of the stopper 342 away from the mounting rod 33. When the stopper 342 is pushed along the guide surface 344 in the direction close to the mounting rod 33, the two stoppers 342 separate from each other under the action of the thrust. A push rod 38 is provided on both sides of the placement rack 313 in the width direction. The push rod 38 is vertically connected to the placement rack 313 for rotation. The placement rack 313 is provided with a locking nut 381 for locking the rotation of the push rod 38. When the wire clamp temperature sensor 1 is installed, the push rod 38 is set downward and is in a storage state.

[0046] The clamp 11 is fixedly connected to a rotating rod 112 coaxial with its own hinge axis. The rotating rod 112 passes through the bracket 12 and extends to both sides of the bracket 12. Abutment rods 122 are vertically hinged on both sides of the bracket 12 along the width direction. The rotating rod 112 is located between all the abutment rods 122 on both sides of the bracket 12. The abutment rods 122 are also fixedly connected to a connecting rod 123 coaxial with their own hinge axis. A bevel gear set 14 is provided between the connecting rod 123 and the rotating rod 112. The bevel gear set 14 includes a bevel gear 141 and a bevel gear 2 142. The bevel gear 141 is coaxially fixed to the rotating rod 112. The bevel gear 2 142 meshes with the bevel gear 141 and is coaxially fixed to the connecting rod 123. When the clamp 11 rotates from the open position to the clamped position under the action of the elastic member 13, it drives the rotating rod 112 to rotate. When the rotating rod 112 rotates, the bevel gear 141 drives the bevel gear 142 to rotate, and the bevel gear 142 drives the contact rod 122 to rotate.

[0047] In the vertical direction, the clamping direction of the clamp 11 is opposite to the rotation direction of the abutting rod 122. When the clamp 11 is in the clamping posture, the abutting rod 122 is in a horizontal state. When it is necessary to disassemble the clamp temperature sensor 1, the ejector rod 38 is adjusted to the working state with the top facing vertically upward. At this time, the operator manipulates the unmanned aerial vehicle 2 to move below the clamp temperature sensor 1 held tightly on the transmission line. When the lower end of the clamp temperature sensor 1 enters the chamber of the placement rack 313 and contacts the second elastic member 32, at this time, the ejector rod 38 corresponds to the abutting rod 122 one by one, and the upper end of the ejector rod 38 faces the lower end of the corresponding abutting rod 122. The operator manipulates the unmanned aerial vehicle 2 to lift. Under the blocking action of the transmission line, the ejector rod 38 drives the abutting rod 122 to rotate. When the abutting rod 122 rotates, it drives the clamp 11 to rotate towards the limiting plate 34 through the helical gear set 14. When the clamp 11 contacts the guiding surface 344 of the stopper 342, it applies pressure to the stopper 342, thereby pushing the two stoppers 342 away from each other. After the clamp 11 enters the limiting groove 341, the stopper 342 is reset under the action of the third elastic member 343, so that the two stoppers 342 cooperate to limit the clamp 11. At this time, the clamp 11 enters the open posture, and the clamp temperature sensor 1 is separated from the transmission line, which is beneficial to further improve the detection convenience.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
