Description

Technical Field

[0001] This invention relates to the field of de-icing technology for high-voltage transmission lines, specifically to a flexible clamping pulse impact de-icing device for high-voltage transmission lines. Background Technology

[0002] High-voltage transmission lines are exposed to the outdoors for extended periods, making them highly susceptible to icing on conductors, ground wires, and insulators under conditions of low temperatures, freezing rain, wet snow, and high humidity in winter. Icing significantly increases conductor load, leading to serious accidents such as increased conductor sag, insufficient phase spacing, ice galloping, tower tilting or even collapse, line breaks, and insulator flashover, severely threatening the safe and stable operation of the power grid. Icing problems are particularly prominent in mountainous areas, high-altitude and cold regions of southern my country, and in microclimate zones. Historically, numerous large-scale ice storms have caused widespread power outages, resulting in enormous economic losses and significant repair pressure.

[0003] Currently, commonly used de-icing technologies both domestically and internationally are mainly classified into several categories, including thermal de-icing, mechanical de-icing, natural de-icing, and electrical pulse de-icing. While thermal de-icing (such as DC and AC de-icing) is reliable, it suffers from drawbacks such as high equipment investment, high energy consumption, the need for power outages, and numerous restrictions on power grid operation, making it difficult to meet the demands for high-frequency, rapid, and uninterrupted de-icing. Traditional mechanical de-icing methods, including manual tapping, pulley scraping, chain friction, and vibration de-icing, present problems such as high operational risks, high labor intensity, low efficiency, easy damage to conductors and fittings, and difficulty in implementation on complex terrains. De-icing robots and UAV-borne de-icing devices developed in recent years, while capable of replacing manual labor, generally suffer from defects such as unstable clamping, narrow wire diameter adaptability, poor obstacle-crossing ability, short endurance, insufficient low-temperature reliability, and poor controllability of impact force, making it difficult to simultaneously achieve safety, high efficiency, and non-destructive de-icing.

[0004] A Chinese invention patent with publication number CN202121108482.4 discloses a high-voltage transmission line maintenance device, including a drone. The drone is equipped with a mounting box, and the mounting box is equipped with two clamps. The two clamps are close to each other to clamp the wire. The mounting box is equipped with a driving component for driving the two clamps to move closer to each other. The side of the clamps used to clamp the wire is provided with an electrothermal layer. This application has the effect of improving the de-icing effect.

[0005] However, the pure contact heating de-icing method is inefficient and has limited effectiveness in breaking thick ice layers and hard, solidified ice. Furthermore, the equipment lacks a flexible buffer and adaptive contact structure, making it difficult for the working components to maintain a tight fit with the conductor under complex conditions such as slight line vibration, line galloping, and conductor offset or tilt. This significantly reduces contact stability and further restricts the overall de-icing effect. Summary of the Invention

[0006] This invention addresses the technical problems existing in the prior art by providing a flexible clamping pulse impact de-icing device for high-voltage transmission lines.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A flexible clamping pulse impact de-icing device for high-voltage transmission lines includes an airfoil propeller. A contact plate is fixedly installed on the lower surface of the airfoil propeller. The bottom of the contact plate is provided with an inverted triangular structure. The contact plate has a through hole. A rope is threaded through the hole and connected to the inside. The lower end of the rope is connected to a clamp. The clamp is composed of a first clamping arm and a second clamping arm. A placement groove A is opened on the inner arc surface of the clamp. The first clamping arm and the second clamping arm together form a receiving opening. An electric drive screw is installed through the bottom of one side wall of the clamp. A connection port is assembled inside the clamp. A stepped groove is machined on the inner arc surface of the connection port. An embedding groove is opened at the front end of the connection port. An avoidance notch is provided at the bottom of the outer arc surface of the connection port. A flexible hinge edge is integrally formed at the top of the connection port away from the notch.

[0008] In a preferred embodiment, a composite ring is nested inside the stepped groove. Flexible clamps are symmetrically arranged on both sides of the inner arc surface of the composite ring. The flexible clamps and the side wall of the composite ring form a deformation cavity. A sealed expansion cavity is opened inside the flexible clamps, and an airbag is fixedly installed inside the expansion cavity.

[0009] In a preferred embodiment, the flexible clamping edges on both sides are fixedly connected to the base plate on their inner sides, an impact scraper is integrally provided on the side of the base plate, an electrode sheet is attached and fixed to the surface of the base plate, and a pulse shell is fixedly covered on the outer side of the electrode sheet.

[0010] In a preferred embodiment, a control switch is embedded at the end of the pulse housing; two sets of pulse housings are provided, and the two sets of pulse housings are arranged radially symmetrically along the connection port, and a control buzzer is fixedly mounted on the inner arc surface of the pulse housing.

[0011] In a preferred embodiment, the outer wall of the airbag is completely fitted against the inner wall of the expansion cavity, and the outer wall of the airbag is tightly fitted with the inner wall of the flexible clamping edge.

[0012] In a preferred embodiment, a clamping member is inserted into the embedding groove at the front end of the connection port. One side of the clamping member is provided with an arc-shaped hinge edge, and the other side of the clamping member is provided with a straight hinge edge.

[0013] In a preferred embodiment, the top of the inner arc surface of the arc-shaped hinge edge is integrally formed with a protruding engagement portion A, and an angular protrusion A is provided on the inner sidewall of the straight hinge edge near one end of the arc-shaped hinge edge. The angular protrusion A and the protruding engagement portion A are arranged facing each other. The outer wall of the arc-shaped hinge edge and the outer wall of the straight hinge edge are respectively attached to and abut against the inner walls of both sides of the clamp.

[0014] In a preferred embodiment, a trapezoidal block B is fixedly provided on the inner bottom surface of the arc-shaped hinge side, and the angular protrusion A adopts a trapezoidal structure that is narrow at the bottom and wide at the top. The sidewall of the angular protrusion A fits and cooperates with the trapezoidal block B, and the angular protrusion A and the protrusion engagement part A enclose each other to form an interface.

[0015] In a preferred embodiment, the front end of the convex engagement portion A is provided with a first through hole, the surface of the angular convex extension A is provided with a second through hole, a tension spring is installed between the first through hole and the second through hole, the tension spring is stored and arranged at the bottom of the interface, the interface and the flexible clamping edge inside the composite ring are at the same horizontal height, and the top of the clamping member is provided with a force-bearing through cavity.

[0016] The beneficial effects of this invention are: By adding a flexible hinged edge to the connection port and an integrated flexible structure with an avoidance gap, the device can adaptively and slightly deflect under harsh conditions such as conductor micro-vibration or wind-induced tilting. It automatically conforms to the real-time posture of the conductor, avoiding hard jamming or excessive local single-point stress. This avoids the technical defects of traditional de-icing devices, such as poor fit and easy disengagement, and improves the continuous operation capability under complex conditions. At the same time, the built-in composite ring, combined with the flexible clamping edge, deformation cavity and airbag combination flexible clamping structure, pushes the flexible clamping edge to adaptively retract inward by the inflation of the airbag, and achieves flexible encirclement and fit by relying on the elastic buffer of the deformation cavity. The clamping force is gentle and controllable, and will not squeeze and damage the outer insulation and metal core of the conductor.

[0017] The integrated pulse impact de-icing mechanism combines electrode plates, pulse shells, and impact scrapers. The electrode plates rapidly and stably conduct high-voltage pulsed electrical energy, while the pulse shell instantly releases high-frequency, millisecond-level high-energy pulse excitation force, which is directly transmitted to the impact scraper through the base plate. This creates an instantaneous cracking impact on thick ice layers and hard, solidified ice, resulting in strong ice-breaking force, fast response speed, and uniform and efficient de-icing. Compared to traditional thermal de-icing, it consumes less energy and is faster; compared to manual de-icing, it is safe and risk-free; and compared to single mechanical ice scraping, it does not damage wires. The overall de-icing effect is significantly improved.

[0018] The front end features an arc-shaped hinge edge, a straight hinge edge, a convex interlocking part, and an angular convex part combined with a tension spring self-locking clamping structure. This, along with an inner flexible clamping structure, provides a solid overall clamping foundation and limit the movement of the clamping mechanism on the outside. The inner flexible structure also helps to protect the cable. The overall structure has strong vibration resistance, and the top force-bearing cavity can disperse the vertical suspension load, preventing localized stress concentration and cracking.

[0019] The system employs a flexible suspension structure with abutment plates and ropes, combined with a bottom inverted triangle guide limit design. This effectively buffers the instantaneous pulling force caused by flight attitude fluctuations and wire dancing, avoids local stress concentration caused by rigid connections, prevents device deformation, structural cracking and clamping displacement, improves the suspension stability and operational reliability of the entire machine under dynamic working conditions in the air, and extends the overall service life of the equipment.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] This embodiment provides a flexible clamping pulse impact de-icing device for high-voltage transmission lines, including a wing propeller 1. A contact plate 2 is fixedly installed on the lower surface of the wing propeller 1. The bottom of the contact plate 2 is provided with an inverted triangular structure. The contact plate 2 has a through hole. A rope is threaded through the hole and connected to the inside. The lower end of the rope is connected to a clamp 3. The clamp 3 is composed of a first clamping arm and a second clamping arm. A placement groove 3A is provided on the inner arc surface of the clamp 3. The first clamping arm and the second clamping arm together form a receiving opening 31. An electric drive screw is installed through the bottom of one side wall of the clamp 3. A connection port 4 is installed inside the clamp 3. A stepped groove 41 is machined on the inner arc surface of the connection port 4. An embedding groove 42 is provided at the front end of the connection port 4. An avoidance notch 43 is provided at the bottom of the outer arc surface of the connection port 4. A flexible hinge edge 44 is integrally formed at the top of the connection port 4 away from the notch 43.

[0024] according to Figures 1 to 3 This device uses an airborne propeller 1 as the aerial load-bearing and moving unit. Relying on the lift generated by the rotation of the propeller, it can achieve horizontal movement and attitude adjustment of the whole machine in the air. It can autonomously approach and align with the section of the high-voltage transmission line to be de-iced. The lower surface of the airborne propeller 1 is fixedly equipped with an abutment plate 2. The bottom end of the abutment plate 2 is equipped with an inverted triangular structure, which has a guiding and correction function. The abutment plate 2 has a through hole, and a rope is inserted into the hole. The clamp 3 below is flexibly suspended by the rope. The flexible connection method of rope suspension can eliminate the hard pulling force caused by flight attitude fluctuations and line sway. Combined with the limiting and guiding function of the abutment plate 2, the lower working components always maintain a relatively stable working attitude, preventing structural deformation and component damage caused by hard pulling.

[0025] The clamp 3 consists of a first clamping arm and a second clamping arm that cooperate to form an integral ring structure. An electric drive screw is installed at the bottom of the side wall of the clamp 3. The rotation of the electric drive screw can control the two sets of clamping arms to complete the opening and closing action, thereby adjusting the clamping diameter to adapt to high-voltage transmission conductors of various specifications and diameters. The inner arc surface of the clamp 3 has a placement groove 3A. The first clamping arm and the second clamping arm together form a receiving opening 31, which provides installation and limiting space for the connection port 4, so that the connection port 4 is stably embedded and fixed inside the clamp 3. The inner arc surface of the connection port 4 is machined with a stepped groove 41 and an embedding groove 42 at the front end, which are used for nesting and installing the composite ring 5 and plugging and assembling the clamping part 10, respectively. The bottom of the outer arc surface of the connection port 4 is provided with an avoidance notch 43, and the top is integrally formed with a flexible hinge edge 44. Relying on the elastic deformation capability of the flexible hinge edge 44, the connection port 4 has an adaptive deflection performance. When the transmission conductor vibrates slightly, the device can make small adaptive adjustments according to the posture of the conductor to ensure that the structure fits tightly and does not come off.

[0026] The stepped groove 41 is nested inside the composite ring 5. Flexible clamping edges 51 are symmetrically arranged on both sides of the inner arc surface of the composite ring 5. The flexible clamping edges 51 and the side wall of the composite ring 5 form a deformation cavity 52. ​​A sealed expansion cavity 53 is opened inside the flexible clamping edge 51. An airbag 54 is fixedly installed inside the expansion cavity 53. The outer wall of the airbag 54 is completely fitted against the inner wall of the expansion cavity 53, and the outer wall of the airbag 54 is tightly fitted with the inner wall of the flexible clamping edge 51.

[0027] like Figure 5 and Figure 6 The composite ring 5 is nested and fixed inside the stepped groove 41 of the connection port 4. It is a ring-shaped elastic adapter base. Two sets of flexible clamping edges 51 are symmetrically arranged on the inner arc surface of the composite ring 5. The flexible clamping edges 51 and the side wall of the composite ring 5 form an independent deformation cavity 52. ​​The deformation cavity 52 provides elastic activity space for the bending and shrinking deformation of the flexible clamping edges 51.

[0028] The flexible clamping edge 51 has an expansion cavity 53 that is sealed inside. An airbag 54 is fixedly arranged inside the expansion cavity 53. The outer wall of the airbag 54 is tightly attached to the inner wall of the expansion cavity 53 and the inner side wall of the flexible clamping edge 51.

[0029] In the initial state, the airbag 54 is in a contracted state, and the flexible clamping edge 51 remains in a naturally open shape with a large clamping diameter, making it easy for the device to be fitted onto the outside of the power transmission line.

[0030] When clamping and fixing are required, the airbag 54 is inflated and pressurized in a controlled manner, gradually expanding in volume and squeezing the wall of the expansion cavity 53 outward. This causes the flexible clamping edge 51 to bend inward towards the center of the conductor, with the connection end with the composite ring 5 as the fulcrum. The deformation cavity 52 is simultaneously compressed and contracted, generating an elastic reaction force, which makes the flexible clamping edge 51 form a flexible hugging posture. The slight expansion adjustment of the airbag 54 and the elastic buffering of the deformation cavity 52 work together. The flexible clamping edge 51 can adjust the curvature of the wrapping in real time according to the outer diameter of the conductor and the thickness of the surface ice, achieving adaptive fitting without hard compression. Under the condition of line micro-vibration tilting and offset, the deformation cavity 52 can reciprocate elastically expand and contract, and the flexible clamping edge 51 swings slightly to relieve force, always maintaining close contact with the surface of the conductor, avoiding local separation, and avoiding scratches and compression damage to the surface of the conductor caused by rigid contact.

[0031] A clamping member 10 is inserted into the embedding groove 42 at the front end of the connection port 4. One side of the clamping member 10 has an arc-shaped hinge edge 101, and the other side has a straight hinge edge 102. The top of the inner arc surface of the arc-shaped hinge edge 101 has an integrally formed protruding engagement portion 101A. An angled protrusion 102A is provided on the inner wall of the straight hinge edge 102 near one end of the arc-shaped hinge edge 101. The angled protrusion 102A and the protruding engagement portion 101A are arranged facing each other. The outer walls of the arc-shaped hinge edge 101 and the straight hinge edge 102 respectively abut against the inner walls of both sides of the clamp 3. A trapezoidal block is fixedly provided on the inner bottom surface of the arc-shaped hinge edge 101. 101B, the angular protrusion 102A adopts a trapezoidal structure that is narrow at the bottom and wide at the top, and the side wall of the angular protrusion 102A fits and cooperates with the trapezoidal block 101B. The angular protrusion 102A and the protrusion engagement part 101A enclose each other to form an interface 103. The front end of the protrusion engagement part 101A is provided with a first through hole, and the surface of the angular protrusion 102A is provided with a second through hole. A tension spring 104 is installed between the first through hole and the second through hole. The tension spring 104 is stored and arranged at the bottom of the interface 103. The interface 103 and the flexible clamping edge 51 inside the composite ring 5 are at the same horizontal height. The top of the clamping member 10 is provided with a force-bearing cavity 105.

[0032] Figure 2 and Figure 4 The clamping member 10 is inserted and limited in the embedding groove 42 at the front end of the connection port 4. It is composed of an arc-shaped hinge side 101 and a straight hinge side 102 to form an opening and closing clamping structure. The outer walls of the two hinge sides abut against the inner walls of the two sides of the clamp 3 respectively. Synchronous linkage is achieved by relying on the opening and closing action of the clamp 3. The top of the arc-shaped hinge side 101 is provided with a protruding engagement part 101A, and the inner bottom surface is fixed with a trapezoidal block 101B. The inner side of the straight hinge side 102 is provided with an angular protrusion 102A with a structure that is narrow at the bottom and wide at the top.

[0033] When the clamp 3 is driven to close and retract by the electric drive screw, it will simultaneously squeeze the arc-shaped hinge edge 101 and the straight hinge edge 102 closer to each other. The angular protrusion 102A slides along the inclined surface of the trapezoidal block 101B to achieve alignment and engagement. At the same time, the protrusion engagement part 101A and the angular protrusion 102A are connected and close together, and the interface 103 between the two gradually shrinks.

[0034] A tension spring 104 is inserted between the through hole of the protruding engagement part 101A and the angular protruding part 102A. The tension spring 104 is housed at the bottom of the mating interface 103. During the clamping and closing process, the two hinged sides rotate relative to each other and stretch the tension spring 104. The tension spring 104 generates a continuous elastic retraction force, which pulls the arc-shaped hinged side 101 and the straight hinged side 102 to engage and lock together, forming a mechanical self-locking structure.

[0035] When the line experiences swaying or impact loads, the arc-shaped hinged edge 101 and the straight hinged edge 102 can generate a small angular deformation through the hinged engagement. The elastic deformation of the tension spring 104 absorbs the vibration load, counteracting the tendency of the structure to loosen. The force-bearing cavity 105 opened at the top of the clamping member 10 can disperse the vertical pressure of the suspension, avoid stress concentration at the hinge position, and ensure that the structure does not deform under long-term clamping conditions.

[0036] The flexible clamping edges 51 on both sides are fixedly connected to the base plate 6 on the inner side. The impact scraper 61 is integrally set on the side of the base plate 6. The electrode sheet 7 is attached and fixed on the surface of the base plate 6. The pulse shell 8 is fixedly covered on the outer side of the electrode sheet 7. The control switch is embedded at the end of the pulse shell 8. Two sets of pulse shells 8 are set. The two sets of pulse shells 8 are arranged radially symmetrically along the connection port 4. The control buzzer 9 is fixedly assembled on the inner arc surface of the pulse shell 8.

[0037] according to Figure 7 The electrode 7 is tightly attached to the surface of the base plate 6 and closely fitted to the inside of the pulse shell 8, serving as a key conductive carrier for pulsed power transmission. After the equipment is powered on, the electrode 7 continuously receives millisecond-level instantaneous high-voltage pulse signals from the main control unit, completing current collection and directional transmission, and stably and evenly guiding the pulse energy into the internal components of the pulse shell 8. The electrode 7 has excellent conductivity and insulation protection properties, which can suppress stray current leakage, control power loss to a low range, and ensure efficient utilization of pulse energy. At the same time, relying on the rigid limit of the base plate 6, the long-term fit can stably withstand high-frequency pulse power-on conditions, providing reliable power conduction conditions for continuous impact de-icing.

[0038] The pulse shell 8 covers the outer side of the electrode plate 7. The two sets of structures are arranged radially symmetrically along the connection port 4. The on / off control is achieved by the end control switch. The pulse shell 8 has a built-in pulse excitation module. After the electrical energy is introduced through the electrode plate 7, it can continuously generate short-cycle high-frequency pulse excitation. The duration of a single impact is controlled at the millisecond level, instantly forming a high-intensity mechanical impact load. The pulse force is synchronously transmitted from the pulse shell 8 to the base plate 6 and the impact scraper 61. It continuously acts on the surface ice layer of the conductor in the form of high-frequency reciprocating micro-vibration combined with instantaneous impact. The high-frequency pulse can quickly cut the internal bonding force of the ice crystal, causing the hard ice layer in the thickness range to quickly generate network cracks. Combined with the contact scraping of the impact scraper 61, the ice layer is quickly peeled off. The two sets of symmetrical structures output force synchronously to offset the torsional torque generated by the single-sided impact, greatly reducing the shaking amplitude of the device during operation and ensuring the structural stability of long-term continuous de-icing.

[0039] The control buzzer 9 is fixedly installed on the inner arc surface of the pulse housing 8 and connected to the overall control circuit. It is an integrated sound and light warning component. When the device completes the alignment and clamping and enters the standby preparation stage, the buzzer emits a low-frequency short-interval beep to indicate that it is in place. During the formal operation of pulse de-icing, it uses intermittent low-frequency sound to provide real-time feedback on the normal operating status of the equipment. When faults such as poor electrode contact, pulse circuit breakage, or abnormal power supply voltage occur, the buzzer immediately switches to a high-frequency continuous long beep warning mode. If abnormal conditions such as clamping loosening or line swing exceeding the threshold are detected, a high-frequency alarm is also triggered to quickly provide feedback on the fault location and dangerous status, which facilitates timely power outage and shutdown by maintenance personnel for troubleshooting and repair, effectively reducing the risk of equipment damage and secondary damage to the line under unmanned field operations.
