Description
Technical Field
[0001] This invention belongs to the technical field of conductor measuring equipment, specifically relating to a device for measuring the diameter of live overhead conductors. Background Technology
[0002] Overhead lines are the core carrier of power transmission, and their conductor diameter directly affects the line's current-carrying capacity, mechanical strength, and operational safety. Accurate measurement of overhead line diameter is a crucial prerequisite for power line operation, maintenance, and upgrades, and is also a key link in ensuring the stable operation of the power system. The measurement of the diameter of energized overhead conductors mainly employs the following methods: Manual live-line measurement: Workers wearing insulated protective gear climb the tower or use insulated rods to contact the energized line, using tools such as calipers to measure and manually read the diameter data. This method suffers from high operational risks, high labor intensity, and low efficiency, and also does not meet the safety distance requirements for live-line work; Remote measurement using drone photography or laser rangefinders: These two remote measurement methods are greatly affected by ambient light and shooting angle, and are significantly influenced by terrain and obstructions, resulting in large measurement errors. It is difficult to ensure that the measuring head maintains the optimal measuring distance from the line, failing to meet the needs of precise operation and maintenance.
[0003] Chinese Patent Publication No. CN117167633A discloses a live measuring tool for the outer diameter of overhead conductors, including a working frame with suspension assemblies at both ends. Each suspension assembly includes a suspension column fixedly connected to the upper surface of the working frame, an arc-shaped frame fixedly connected to the suspension column, an arc-shaped groove at the upper end of the arc-shaped frame, an arc-shaped strip slidably connected within the arc-shaped groove, and an arc-shaped spring fixedly connected to the side wall of the arc-shaped strip near the suspension column, the arc-shaped spring being disposed within the arc-shaped groove. A measuring component is provided on the working frame. This device performs measurements using an electric measuring ruler, reducing the reading pressure on workers operating at heights and increasing measurement accuracy.
[0004] However, when using the above devices, the arc strip needs to be retracted into the arc groove first, then the arc frame is hung on the overhead conductor, and the limit plate is released. The arc frame can then work with the arc strip and the suspension column to complete the closure. Then, the same operation is used to hang another suspension component on the conductor before measurement can be carried out. When taking it down, the opposite steps need to be repeated. The whole operation process is too cumbersome, which increases the operation time and adds to the workload of the workers at high altitudes. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, such as cumbersome operation, low measurement accuracy, and insufficient safety, in measuring devices for measuring the diameter of live overhead conductors.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a live overhead conductor diameter measuring device, comprising an insulation operating mechanism, a clamping measuring mechanism, and a data processing mechanism. The insulation operating mechanism includes an insulation telescopic rod and an operating handle. The operating handle is fixed to the bottom end of the insulation telescopic rod, and the top end of the insulation telescopic rod is detachably connected to the clamping measuring mechanism via a threaded plug. The clamping measuring mechanism includes a clamping seat, with a socket with a screw hole at the bottom of the clamping seat. A fixed clamping block is fixedly disposed inside the clamping seat, and a movable clamping block is slidably disposed corresponding to the position of the fixed clamping block. An elastic element is disposed between the side of the movable clamping block away from the fixed clamping block and the clamping seat, providing a force for the movable clamping block to move closer to the fixed clamping block. A data processing mechanism is disposed outside the clamping seat, comprising a displacement sensor and a data processor. A displacement transmission component is disposed between the displacement sensor and the movable clamping block, transmitting the displacement of the movable clamping block to the displacement sensor. The data processor processes the data collected by the displacement sensor to obtain the conductor diameter data and transmits it remotely.
[0007] Furthermore, the displacement sensor type can be a rotary encoder, etc., preferably a dedicated anti-magnetic encoder, which can accurately collect the displacement transmitted by the displacement transmission component and ensure the accuracy of the measurement data.
[0008] The clamping seat consists of two symmetrical halves connected by fixing screws, which facilitates the disassembly and installation of the clamping seat and the maintenance and repair of its internal components.
[0009] The clamping seat is horizontally provided with a limiting rod inside, and the movable clamping block is provided with a limiting groove on the outside of the limiting rod at the position corresponding to the limiting rod. The movable clamping block can slide along the limiting rod through the limiting groove. The limiting rod and the limiting groove cooperate to limit the sliding direction of the movable clamping block, prevent the movable clamping block from deviating, and ensure the stability of clamping and the accuracy of displacement acquisition.
[0010] Both the side of the movable clamping block away from the fixed clamping block and the inside of the clamping seat are provided with receiving grooves. The elastic element is placed inside the receiving groove. The receiving groove plays a role in positioning and protecting the elastic element, preventing the elastic element from shifting or falling off, and ensuring that the elastic element can stably provide the force for the movable clamping block to move closer to the fixed clamping block.
[0011] The displacement transmission component includes a transmission rack and a transmission gear. The transmission rack is fixedly installed at the bottom of the movable clamping block, and the transmission gear is rotatably installed inside the clamping seat. The transmission rack and the transmission gear mesh with each other. The shaft of the transmission gear is fixedly connected to the displacement sensor. When the movable clamping block slides, it drives the transmission rack to move, and the transmission rack drives the transmission gear to rotate, thereby driving the displacement sensor to collect the rotational displacement, so as to realize the accurate transmission and collection of displacement.
[0012] An auxiliary guiding mechanism is provided above the clamping and measuring mechanism. The auxiliary guiding mechanism includes a guide rod, which is located at the upper end of the fixed clamping block and the movable clamping block. It is used to guide the wire into the clamping and measuring mechanism. Pulleys are symmetrically arranged on the sides of the guide rods that are close to each other. A sliding belt is provided between the two pulleys. The guide rod can guide the wire to enter the space between the fixed clamping block and the movable clamping block quickly and accurately. The sliding belt can reduce the friction between the wire and the guide rod, avoid damage to the surface of the wire, and at the same time help the wire to enter the clamping area smoothly.
[0013] An angle adjustment assembly is provided between the fixed clamping block, the movable clamping block, and the guide rod. The angle adjustment assembly includes a first bevel gear, a second bevel gear, and a control button. The first bevel gear is fixedly connected to the lower end of the guide rod and can rotate around its axis. The second bevel gear is arranged opposite to and cooperates with the first bevel gear. A sleeve is provided on the side of the second bevel gear away from the first bevel gear. The control button is located outside the fixed clamping block and the movable clamping block. The control button and the sleeve are connected by a coupling. The control button can drive the second bevel gear to move closer to or away from the first bevel gear through the coupling and the sleeve, thereby locking and releasing the first bevel gear. This facilitates the adjustment of the guide rod angle according to the wire erection angle, improves the accuracy of guidance, and adapts to the wire measurement needs of different erection angles.
[0014] A spring is provided on the side of the wheel sleeve away from the second bevel gear. The spring provides a force to bring the second bevel gear closer to the first bevel gear, ensuring that the second bevel gear and the first bevel gear can mesh stably, realizing reliable locking of the guide rod angle, and preventing the guide rod from rotating during the measurement process, which would affect the guiding effect.
[0015] The insulating telescopic rod has multiple overlapping insulating inner rods inside, which are locked together by a quick-locking mechanism. This allows for easy adjustment of the length of the insulating telescopic rod, adapting to the measurement needs of overhead conductors at different heights and improving the adaptability of the device.
[0016] The quick-locking mechanism includes a lock groove and a lock seat. The lock groove is located on the outer surface of the insulating inner rod, and the lock seat is located at the end of the adjacent outer insulating inner rod. The lock seat and the lock groove are positioned corresponding to each other. The lock seat includes an eccentric wheel and a shift plate. The eccentric wheel is rotatably disposed inside the lock seat, and a paddle is fixedly disposed on the outer side of the eccentric wheel. The shift plate is located on the side of the eccentric wheel away from the paddle and can move inside the lock seat. A top block is disposed on the side of the shift plate near the eccentric wheel, and a locking block is disposed on the side of the shift plate away from the eccentric wheel. The shape of the locking block matches the lock groove. By rotating the eccentric wheel, the top block can drive the shift plate to move, thereby realizing the engagement or disengagement of the locking block and the lock groove, thus achieving quick locking and unlocking of the insulating inner rod. The operation is convenient and the locking is reliable.
[0017] This invention provides a device for measuring the diameter of live overhead conductors, which has the following advantages: This device features a rational structure and convenient operation, enabling accurate measurement of live conductor diameters without power outages. This avoids the cumbersome procedures and disruptions to residential electricity supply associated with power outages. The device can be pre-assembled and adjusted on the ground, eliminating the need for tedious high-altitude operations. Depending on the specific specifications of the overhead conductor, operators can choose whether pole climbing is required, enabling remote operation via an insulated operating mechanism, significantly improving safety and increasing efficiency.
[0018] The clamping and measuring mechanism features a rational structure. The fixed clamping block and the movable clamping block work together, achieving stable clamping of the wire under the action of the elastic element. The cooperation between the limiting rod and the limiting groove prevents the movable clamping block from shifting. The displacement transmission component, through the meshing of the transmission rack and gear, accurately transmits the displacement of the movable clamping block to the displacement sensor. Combined with the conversion processing of the data processor, accurate measurement of wire diameter data is achieved, and remote transmission of the wire diameter data is realized. Operators can receive the measurement data on the ground. The measurement accuracy is not affected by human factors. Compared with existing manual reading methods, the accuracy is greatly improved, further enhancing operational safety and efficiency.
[0019] The system is equipped with an auxiliary guiding mechanism and an angle adjustment component. The guide rod can guide the wire to quickly enter the clamping area, and the sliding belt protects the wire surface from damage. The angle adjustment component can flexibly adjust the angle of the guide rod according to the wire installation angle to adapt to different installation scenarios, thus solving the problems of difficult wire guidance and poor adaptability of existing devices.
[0020] The insulated telescopic rod adopts a multi-section insulated inner rod overlapping design, combined with a quick-locking mechanism to achieve rapid length adjustment and reliable locking. It is easy to operate and can be adapted to the measurement needs of overhead conductors at different heights, making it highly versatile. The insulated operating mechanism and the clamping measuring mechanism are connected by threads, and the detachable design facilitates the carrying, transportation and maintenance of the device.

[0034] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0035] Please see Figures 1 to 5 A live overhead conductor diameter measuring device includes an insulation operating mechanism 1, a clamping measuring mechanism 2, and a data processing mechanism 3. The mechanisms work together to achieve accurate, safe, and efficient measurement of the diameter of live overhead conductors.
[0036] The insulated operating mechanism 1 is used for remote operation by the operator to avoid close contact with live wires and ensure work safety. It includes an insulated telescopic rod 102 and an operating handle 101. The operating handle 101 is fixed to the bottom end of the insulated telescopic rod 102 and is made of non-slip and insulating material, which is convenient for the operator to hold and operate. The top end of the insulated telescopic rod 102 is detachably connected to the clamping and measuring mechanism 2 through a threaded plug 1021. The threaded connection method facilitates disassembly and installation, and makes it convenient for the device to be carried, transported and maintained.
[0037] The clamping and measuring mechanism 2 is used to stably clamp a live conductor and transmit the displacement corresponding to the conductor diameter. It includes a clamping base 201, with a socket 205 having a screw hole at its bottom. The socket 205 is threadedly engaged with a threaded plug 1021 at the top of the insulating telescopic rod 102, enabling a detachable connection between the clamping and measuring mechanism 2 and the insulating operating mechanism 1. The clamping base 201 consists of two symmetrical halves 2011 connected by fixing screws 2012. Removing the fixing screws 2012 allows the clamping base 201 to be disassembled, facilitating the installation, maintenance, and repair of internal components.
[0038] A fixed clamping block 202 is fixedly installed inside the clamping base 201. The fixed clamping block 202 is fixedly connected to the inner wall of the clamping base 201. A movable clamping block 203 is slidably installed at the position corresponding to the fixed clamping block 202. The movable clamping block 203 can slide along the inside of the clamping base 201, moving closer to or away from the fixed clamping block 202. An elastic element 2031 is provided between the side of the movable clamping block 203 away from the fixed clamping block 202 and the clamping base 201. The elastic element 2031 is preferably a spring. The elastic element 2031 provides a force for the movable clamping block 203 to move closer to the fixed clamping block 202, ensuring that the wire is stably clamped between the fixed clamping block 202 and the movable clamping block 203, and avoiding the wire from shaking during the measurement process, which would affect the measurement accuracy.
[0039] In order to position and protect the elastic element 2031, the movable clamping block 203 is provided with a receiving groove 2032 on the side away from the fixed clamping block 202 and inside the clamping seat 201. The elastic element 2031 is placed inside the receiving groove 2032. The size of the receiving groove 2032 is adapted to the elastic element 2031 to prevent the elastic element 2031 from shifting or falling off, and to ensure that the elastic element 2031 can stably provide clamping force.
[0040] To prevent the movable clamping block 203 from shifting during sliding, a limiting rod 2013 is horizontally installed inside the clamping base 201. The two ends of the limiting rod 2013 are fixedly connected to the inner wall of the clamping base 201. A limiting groove 2014 is provided on the outer side of the movable clamping block 203 at the position corresponding to the limiting rod 2013. The limiting groove 2014 slides in cooperation with the limiting rod 2013. The movable clamping block 203 can slide smoothly along the limiting rod 2013 through the limiting groove 2014, ensuring that the sliding direction of the movable clamping block 203 remains parallel to the center line of the fixed clamping block 202, thus ensuring the accuracy of displacement acquisition.
[0041] A data processing mechanism 3 is provided on the outside of the clamping base 201. The data processing mechanism 3 is used to collect displacement data, convert wire diameter data, and transmit it remotely. It includes a displacement sensor 301 and a data processor 302. The displacement sensor 301 is fixedly installed on the outside of the clamping base 201. The data processor 302 is electrically connected to the displacement sensor 301. The data processor 302 has a built-in wireless transmission module, which can remotely transmit the processed wire diameter data to a ground receiving device, allowing operators to view the measurement results in real time. The displacement sensor 301 can be a rotary encoder, etc. Rotary encoders have the advantages of high measurement accuracy and fast response speed, and can accurately collect the displacement transmitted by the displacement transmission component 204.
[0042] A displacement transmission component 204 is provided between the displacement sensor 301 and the movable clamping block 203. The displacement transmission component 204 is used to convert the linear displacement of the movable clamping block 203 into a rotational displacement and transmit it to the displacement sensor 301. Specifically, the displacement transmission component 204 includes a transmission rack 2041 and a transmission gear 2042. The transmission rack 2041 is fixedly disposed at the bottom of the movable clamping block 203 and extends along the sliding direction of the movable clamping block 203. The transmission gear 2042 is rotatably disposed inside the clamping seat 201 via a rotating shaft. The transmission rack 2041 and the transmission gear 2042 mesh with each other. The shaft of the transmission gear 2042 can be fixedly connected to the input shaft of the displacement sensor 301 via a coupling.
[0043] In this embodiment, the clamping and measuring mechanism 2 is threadedly connected to the threaded plug 1021 at the top of the insulating telescopic rod 102 via the socket 205, thus completing the device assembly. The operator holds the operating handle 101 and lifts the device to the position of the overhead conductor. When the conductor enters between the fixed clamping block 202 and the movable clamping block 203, the conductor pushes the movable clamping block 203 to slide away from the fixed clamping block 202. The movable clamping block 203 drives the transmission rack 2041 to move synchronously, which in turn drives the transmission gear 2042 to rotate. The transmission gear 2042 then drives the input shaft of the displacement sensor 301 to rotate. The displacement sensor 301 collects the rotational displacement and transmits it to the data processor 302. The data processor 302 converts the rotational displacement into conductor diameter data according to a preset conversion formula, completing the measurement and remote transmission.
[0044] Please see Figures 6 to 9 In another embodiment, to facilitate the rapid and accurate entry of the wire into the clamping and measuring area, an auxiliary guiding mechanism 4 is provided above the clamping and measuring mechanism 2. The auxiliary guiding mechanism 4 includes a guide rod 401, which is disposed on the upper end of the fixed clamping block 202 and the movable clamping block 203. The ends of the guide rods 401 that are close to each other are inclined towards the clamping area to form a trumpet-shaped guide opening, which facilitates the guidance of the wire into the space between the fixed clamping block 202 and the movable clamping block 203. Pulleys 4011 are symmetrically arranged on the sides of the guide rods 401 that are close to each other. A sliding belt 4012 is provided between the two pulleys 4011. The sliding belt 4012 is made of wear-resistant and insulating material. When the wire comes into contact with the sliding belt 4012, the sliding belt 4012 can roll with the wire, reducing the friction between the wire and the guide rod 401, avoiding damage to the wire surface, and at the same time assisting the wire to enter the clamping area smoothly.
[0045] In order to accommodate wires at different installation angles, an angle adjustment component 402 is provided between the fixed clamping block 202, the movable clamping block 203 and the guide rod 401. The angle adjustment component 402 is used to adjust the angle of the guide rod 401 and to lock the angle.
[0046] Specifically, the angle adjustment assembly 402 includes a first bevel gear 4021, a second bevel gear 4022, and a control button 4024. The first bevel gear 4021 is fixedly connected to the lower end of the guide rod 401 and can rotate around the axis of the guide rod 401. The second bevel gear 4022 is arranged opposite to and cooperates with the first bevel gear 4021. A sleeve 4023 is provided on the side of the second bevel gear 4022 away from the first bevel gear 4021. The sleeve 4023 is fixedly connected to the second bevel gear 4022. The control button 4024 is located outside the fixed clamping block 202 and the movable clamping block 203. The control button 4024 and the sleeve 4023 are connected by a coupling shaft 4025. The coupling shaft 4025 is fixedly connected to the sleeve 4023 and the control button 4024, and can move axially with the control button 4024. A spring 4026 is provided on the side of the wheel sleeve 4023 away from the second bevel gear 4022. The spring 4026 is sleeved on the outside of the connecting shaft 4025, with one end fixedly connected to the wheel sleeve 4023 and the other end fixedly connected to the inner wall of the clamping seat 201. The spring 4026 is in a compressed state, providing a force for the second bevel gear 4022 to move closer to the first bevel gear 4021, ensuring stable meshing between the second bevel gear 4022 and the first bevel gear 4021, and locking the angle of the guide rod 401.
[0047] In this embodiment, the angle of the guide rod 401 is adjusted according to the overhead conductor. The control button 4024 is pulled outward. The control button 4024 drives the wheel sleeve 4023 and the second bevel gear 4022 to move away from the first bevel gear 4021 through the connecting shaft 4025. The spring 4026 is further compressed, and the second bevel gear 4022 separates from the first bevel gear 4021, releasing the restriction on the first bevel gear 4021. At this time, the guide rod 401 can be rotated. After adjusting to a suitable angle, the control button 4024 is released, the spring 4026 returns to its original position, and pushes the wheel sleeve 4023 and the second bevel gear 4022 closer to the first bevel gear 4021. The second bevel gear 4022 and the first bevel gear 4021 re-mesh, realizing the locking of the angle of the guide rod 401. The operation is convenient and the locking is reliable. The overhead conductor is guided into the auxiliary guide mechanism 4 through the funnel-shaped guide opening formed by the guide rod 401. The conductor contacts the sliding belt 4012 and smoothly enters between the fixed clamping block 202 and the movable clamping block 203 with the assistance of the sliding belt 4012.
[0048] Please see Figures 10 to 12 In another embodiment, multiple insulating inner rods 5 are stacked inside the insulating telescopic rod 102. The insulating inner rods 5 are made of high-strength insulating material to ensure the safety of live-line work. The insulating inner rods 5 are locked together by a quick-locking mechanism, which facilitates the adjustment of the overall length of the insulating telescopic rod 102 to meet the measurement needs of overhead conductors at different heights.
[0049] Specifically, the quick-lock mechanism includes a lock groove 501 and a lock seat 502. The lock groove 501 is located on the outer surface of the insulating inner rod 5 and is arranged along the length of the insulating inner rod 5. The lock seat 502 is located at the end of the adjacent outer insulating inner rod 5, and the lock seat 502 and the lock groove 501 are positioned corresponding to each other. The lock seat 502 includes an eccentric wheel 5021 and a shift plate 5023. The eccentric wheel 5021 is rotatably disposed inside the lock seat 502, and a lever 5022 is fixedly disposed on the outer side of the eccentric wheel 5021. The lever 5022 extends to the outside of the lock seat 502, allowing for quick locking. The operator can move the shift plate 5023; the shift plate 5023 is located on the side of the eccentric wheel 5021 away from the shift piece 5022. The shift plate 5023 can move horizontally inside the lock seat 502. A top block 5024 is provided on the side of the shift plate 5023 near the eccentric wheel 5021. The top block 5024 is in contact with the surface of the eccentric wheel 5021. A locking block 5025 is provided on the side of the shift plate 5023 away from the eccentric wheel 5021. The shape of the locking block 5025 matches the locking groove 501 and has an arc structure, which is in contact with the outer surface of the insulating inner rod 5.
[0050] In this embodiment, when adjusting the length of the insulating telescopic rod 102, the paddle 5022 is turned to drive the eccentric wheel 5021 to rotate. The eccentric wheel 5021 moves away from the moving plate, allowing the locking block 5025 to disengage from the locking groove 501. This allows the insulating inner rod 5 to be pulled to adjust its length. After adjusting to the appropriate length, the paddle 5022 is turned in the opposite direction, the eccentric wheel 5021 resets, and the moving plate 5023 resets under its own weight and the squeezing action of the eccentric wheel 5021. The locking block 5025 then engages in the corresponding locking groove 501, achieving quick locking of the insulating inner rod 5. This method is convenient to operate and provides reliable locking.
[0051] After the measurement is completed, the operator holds the operating handle 101 and slowly lowers the device. The overhead wire is released from the clamping measuring mechanism 2, and the moving clamping block 203 is reset under the elastic force of the elastic element 2031. The displacement sensor 301 and the data processor 302 are turned off. The quick-lock mechanism is adjusted to retract the insulating telescopic rod 102 to its shortest length and lock it. The clamping measuring mechanism 2 and the insulating operating mechanism 1 are disassembled. The device is cleaned, inspected and stored for future use.
[0052] This device features a reasonable structure and convenient operation, enabling precise measurement of the diameter of live conductors without power outages. It can be assembled and adjusted on the ground beforehand, eliminating the need for cumbersome operations at heights. It offers high measurement accuracy and strong safety, adapting to the measurement needs of overhead conductors at different heights and installation angles. Furthermore, it enables remote transmission of conductor diameter data, improving testing efficiency.
