Description

Technical Field

[0001] This invention relates to the field of power transmission line maintenance, and in particular to a high-frequency micro-amplitude vibration crushing ice-breaking device. Background Technology

[0002] During the operation of power transmission lines, low temperatures in winter can easily cause ice to form on the surface of transmission conductors. The accumulation of ice can increase the load on the conductors and may lead to safety accidents such as conductor breakage and tower collapse, seriously affecting the stable operation of the power system. Therefore, de-icing of power transmission lines is an important task in power maintenance.

[0003] Currently, there are various methods for de-icing transmission lines. Mechanical knocking de-icing relies on impact force to break the ice layer, which is a hard contact method. However, this method is prone to conductor fatigue and insulator loosening. High-voltage de-icing melts ice by heating it with current, which relies on heat conduction. This method is not only extremely energy-intensive but also requires a special transformer and may damage the line insulation layer. Hot air de-icing uses high-temperature airflow to melt the ice layer, but its high temperature can easily burn the conductor sheath. Single rolling de-icing breaks the ice layer by mechanical cutting, which has low work efficiency.

[0004] These existing de-icing methods generally suffer from incomplete de-icing, poor work efficiency, and significant damage to power transmission lines. They cannot effectively protect power transmission lines while quickly and thoroughly breaking up ice. Therefore, there is an urgent need for a power transmission line de-icing device that can solve the above problems. Summary of the Invention

The crushing ice-breaking components are provided in at least two sets. The crushing ice-breaking components include rotating rollers. The two sets of rotating rollers are used to clamp on both sides of the surface of the power transmission line. When the rotating rollers rotate, they can drive the entire device to move along the surface of the power transmission line. When the rotating rollers move along the surface of the power transmission line, their blades can penetrate the ice layer on the surface of the power transmission line, causing the ice layer to crack and break.

[0011] In a preferred embodiment of the high-frequency micro-amplitude vibration crushing ice device of the present invention: the crushing ice component further includes a transmission shaft connected to the rotating roller and a drive motor connected to the transmission shaft, the drive motor is connected to the side wall of the connecting plate, and the top of the connecting plate is connected to the slider; when the adjusting motor drives the rolling screw to rotate, the two sets of sliders drive the two sets of connecting plates to move in opposite directions.

[0012] In a preferred embodiment of the high-frequency micro-amplitude vibration crushing ice crushing device of the present invention: the shock-absorbing component includes a receiving block connected to the bottom end of the support, a spring disposed on the inner wall of the receiving block, a central shaft passing through the spring, and a fixing block sleeved on the outer wall of the central shaft, the fixing block being fixedly connected to the bottom end of the receiving block; one end of the spring is connected to the fixing block, the other end of the spring is connected to a moving block, one end of the central shaft is connected to the moving block, and the other end of the central shaft passes through the fixing block and is connected to the vibration plate at the bottom end of the receiving block.

[0014] In a preferred embodiment of the high-frequency micro-amplitude vibration crushing ice crushing device of the present invention: the bottom of both ends of the support is connected to a load-bearing wheel, which is a U-shaped groove wheel, and is engaged with the surface of the power transmission line through the U-shaped groove during use.

[0015] In a preferred embodiment of the high-frequency micro-amplitude vibration crushing ice-breaking device of the present invention: at least two sets of blades are arranged around the outer wall of the rotating roller, and an ice-breaking gap is provided between two adjacent sets of blades.

This solves the technical problem in the existing technology of how to quickly and thoroughly break ice on the transmission line while reducing damage to the transmission line.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0022] Reference Figure 1 , Figure 2 and Figure 5 This embodiment provides a high-frequency micro-amplitude vibration crushing ice device, including a support 1 and crushing ice components 2 disposed on both sides of the bottom end of the support 1. The crushing ice components 2 are provided in at least two sets. In this embodiment, the crushing ice components 2 are set to two sets as an example for detailed description. In actual use, the crushing ice components 2 can be set to four sets or even more depending on the usage situation.

[0023] Furthermore, refer to Figure 5 and Figure 6The ice crushing component 2 includes a rotating cutter 21, a drive shaft 22 connected to the rotating cutter 21, and a drive motor 23 connected to the drive shaft 22. At least two sets of blades 25 are arranged around the outer wall of the rotating cutter 21. The length of the rotating cutter 21 perpendicular to the ground should be greater than the diameter of the power transmission line X, thus increasing the contact area between the rotating cutter 21 and the power transmission line X. It should be noted that by clamping the rotating cutter 21 to both sides of the power transmission line X, and cooperating with the load-bearing wheel 6, the rotating cutter 21 can fix the entire device to the surface of the power transmission line X. When the rotating cutter 21 rotates, it can drive the entire device to move along the surface of the power transmission line X. As the rotating cutter 21 moves the entire device along the surface of the power transmission line X, the blades 25 can penetrate the ice layer G on the surface of the power transmission line X, causing the ice layer G to break, crack, or fall off, thereby achieving preliminary de-icing. In other words, the rotating cutter 21 in this invention simultaneously has the functions of clamping, driving, and crushing ice.

[0024] Furthermore, refer to Figure 3 and Figure 4 A high-frequency vibration component 3 is provided at the bottom of the support 1. The high-frequency vibration component 3 includes a power amplifier 31 and a signal generator 32 located at the top of the vibration plate 46, and a vibrator 33 located at the bottom of the vibration plate 46. It should be noted that the signal generator 32 generates a specific high-frequency reference electrical signal adapted to the icing condition. The power amplifier 31 amplifies this weak signal into a strong electrical signal with driving capability. After receiving the strong electrical signal, the vibrator 33 converts it into high-frequency micro-amplitude mechanical vibration, which is transmitted to the transmission line and residual icing through the vibration head, destroying the adhesion between the icing and the line, causing the residual icing to completely fall off, and achieving complete removal of the residual icing.

[0025] It should be noted that an ice-breaking gap 26 is provided between two adjacent sets of blades 25, as shown in the reference. Figure 6 As shown, in this embodiment, multiple sets of blades 25 are evenly distributed around the outer periphery of the rotating cutter 21. The more blades 25 on the outer wall of the rotating cutter 21, the more cracks are generated on the surface of the ice layer G when the rotating cutter 21 rolls along the ice layer G. This allows the ice layer G to break into more parts, thus performing initial de-icing. It should be noted that the cracks generated when the blades 25 of the rotating cutter 21 insert into the inner wall of the ice layer G can also provide force points for subsequent high-frequency micro-amplitude vibration. The more cracks there are, the more force points there are, which is more conducive to the ice layer G breaking apart from the surface of the transmission line X under the action of vibration. This is because high-frequency micro-amplitude vibration can penetrate the thin ice and broken ice tightly attached to the line surface, destroying the molecular adhesion (van der Waals force, ice-binding force) between the ice and the line. Even the stubborn thin ice remaining after crushing can be completely removed, avoiding the problem of "incomplete de-icing leading to secondary icing".

[0026] In short, the working principle of this invention is that after the rotating cutter 21 is inserted into the ice layer G, it generates concentrated impact and shear force on the ice, thereby breaking the entire ice layer G into multiple points where force can be applied (gaps), and at the same time causing the ice to detach initially. Then, the remaining ice is further broken by high-frequency vibration and the adhesion between the remaining ice and the surface of the power transmission line is eliminated, so that the remaining ice also falls off, thereby achieving the de-icing effect.

[0027] This invention combines the initial de-icing of the ice layer G by a rotating roller cutter 21 with the high-frequency micro-amplitude vibration of a vibrator 33 to form a continuous operation process. As the device moves along the line, it simultaneously removes ice, eliminating the need for repeated back-and-forth movements. This improves operational efficiency and enables thorough de-icing of the surface of the transmission line X.

[0028] Compared to existing technologies, mechanical knocking relies on impact force to break the ice layer G, which is a hard contact method, but mechanical knocking is prone to causing conductor fatigue and insulator loosening; high-voltage de-icing melts ice by heating with current, with heat conduction as the core, but high-voltage de-icing is not only extremely energy-intensive and requires a special transformer, but may also damage the line insulation layer; hot air de-icing uses high-temperature airflow to melt the ice layer G, but the high temperature of hot air de-icing may burn the conductor sheath; single rolling breaks the ice layer G by mechanical cutting, but all of the above ice-breaking methods are inefficient and cause significant damage to the transmission line X.

[0029] This invention utilizes the high-frequency, low-amplitude vibration characteristic of the vibrator 33 for de-icing. The de-icing process is shock-free and heat-free, significantly reducing damage to the power line. During use, it avoids the resonance range between the vibration frequency and the natural frequency of the transmission line, and the vibration amplitude is small, constituting localized "micro-amplitude vibration," thus preventing fatigue damage to conductors, insulators, and other components. Compared to mechanical impacts and high-voltage surges, it offers superior protection for the power line. Furthermore, the combination of preliminary de-icing by the rotating cutter 21 and the high-frequency, low-amplitude vibration de-icing by the vibrator 33 effectively removes both thin ice and stubborn ice fragments.

[0030] In some implementations, refer to Figure 1 , Figure 3 and Figure 4 The high-frequency vibration component 3 is connected to a shock-absorbing component 4 at its top end. The end of the shock-absorbing component 4 away from the high-frequency vibration component 3 is connected to the bottom end of the support 1. The shock-absorbing component 4 is used to absorb the vibration energy generated by the high-frequency vibration component 3 when it is working, which significantly reduces the impact of high-frequency vibration on the overall structure of the device and prevents the component from becoming loose or damaged.

[0031] Furthermore, refer to Figure 1 , Figure 3 and Figure 4The shock-absorbing component 4 includes a receiving block 41 connected to the bottom end of the bracket 1, a spring 42 disposed on the inner wall of the receiving block 41, a central shaft 43 passing through the spring 42, and a fixing block 44 sleeved on the outer wall of the central shaft 43. The fixing block 44 is fixedly connected to the bottom end of the receiving block 41. One end of spring 42 is connected to fixed block 44, and the other end of spring 42 is connected to moving block 45. One end of central shaft 43 is connected to moving block 45, and the other end of central shaft 43 passes through fixed block 44 and the bottom end of receiving block 41 is connected to vibrating plate 46. The bottom end of vibrating plate 46 is connected to vibrator 33.

[0032] In operation, the bottom end of the vibrator 33 contacts the surface of the power transmission line X. By contacting and striking the ice layer G with the high-frequency vibrating end, the ice is broken up and removed more thoroughly. When the vibrator 33 vibrates, it pushes the moving block 45 up and down on the inner wall of the receiving block 41 via the central shaft 43 connected to the vibrating plate 46, allowing the spring 42 to absorb the vibration force generated by the vibrator 33. It should be noted that there is a movement gap 47 between the top of the moving block 45 and the inner wall of the receiving block 41, which allows the moving block 45 to move up and down on the inner wall of the receiving block 41 when subjected to the vibration force of the vibrator 33, and also allows the vibrator 33 to adapt to ice layers G of different thicknesses.

[0033] In some implementations, refer to Figure 1 and Figure 5 The bottom of the bracket 1 is connected to an adjustment component 5, which is connected to the ice crushing component 2. The adjustment component 5 is used to adjust the straight distance between the two sets of ice crushing components 2, so that the two sets of ice crushing components 2 can clamp power transmission wires X of different diameters.

[0034] Furthermore, refer to Figure 5 The adjusting component 5 includes a rolling screw 51 with connecting blocks at both ends and an adjusting motor 52 connected to the rolling screw 51. The rolling screw 51 passes through two sets of sliders 53, and the top of the connecting block is connected to the bottom of the bracket 1. It should be noted that the drive motor 23 is connected to the side wall of the connecting plate 24, and the top of the connecting plate 24 is connected to the slider 53. When the adjusting motor 52 drives the rolling screw 51 to rotate, the two sets of sliders 53 drive the two sets of connecting plates 24 to move in opposite directions. Thus, when the rolling screw 51 rotates clockwise, the two sets of connecting plates 24 move towards each other, and the straight-line distance between the two sets of rotating cutters 21 becomes shorter. When the moving screw rotates counterclockwise, the two sets of connecting plates 24 move away from each other, and the straight-line distance between the two sets of rotating cutters 21 becomes longer. By adjusting the rotation of the rolling screw 51 driven by the motor 52, the distance between the two sets of rotating cutters 21 can be adjusted, so that the whole device can adapt to transmission wires X of different diameters. At the same time, it is convenient for the whole device to be placed on the surface of the transmission wire X, and the rotating cutters 21 can be kept in a clamped state with the transmission wire X by adjusting the distance between the two sets of rotating cutters 21.

[0035] Operation Procedure: The device is transported to the designated location on the power line de-icing line using a drone, ensuring no personnel are present below. The drone, controlled by a remote control system and equipped with a camera, is then lowered slowly after aligning the U-shaped groove of the de-icing device's support roller 6 with the power line, until the power line is in close contact with the surface of the U-shaped groove and the device is horizontally balanced. The drone's camera is then used to monitor stability before proceeding with further operations.

[0036] The remote control system sends corresponding spacing adjustment commands to start the adjustment motor 52. After receiving the signal, the adjustment motor 52 drives the rolling screw to rotate, thereby adjusting the spacing until both sets of rotating cutters 21 simultaneously clamp the transmission line X. This allows the entire device to be stably positioned on the surface of the transmission line X through the cooperation of the rotating cutters 21 and the load-bearing wheel 6. Then, based on the pre-measured line diameter and corresponding ice thickness, the drive motor 23 is remotely controlled to rotate. The camera mounted on the drone remotely monitors and observes the contact between the gear cutters and the ice, ensuring that the spacing is appropriate and that the cutter blades 25 can accurately embed into the ice surface without excessive compression or excessive gaps.

[0037] After the spacing adjustment is completed and the adjustment motor 52 stops rotating, the drive motor 23 is started by sending a corresponding command through the remote control system. The drive motor 23 drives the transmission shaft 22 and the rotating cutter 21 to rotate. The cutter blade 25 is embedded in the ice layer G. Through the concentrated impact force and shear force generated by the rotation, the continuous ice layer G is broken into fragments with gaps and initially falls off. At the same time, the drive device moves slowly forward along the power transmission line.

[0038] As the device moves forward, after the crushing and ice-breaking device completes the initial crushing of a certain section of the line, the remote control system sends a corresponding command to control the high-frequency vibration component 3 to start. The high-frequency vibration component 3 generates high-frequency micro-amplitude vibration, and the vibrating head directly acts on the residual ice on the surface of the line. The vibration energy is transferred to the interior of the ice, destroying the adhesion between the ice and the line, causing the residual ice to further break up and fall to the ground.

[0039] The device moves continuously along the power transmission line, maintaining a combined operation mode of "crushing and initial de-icing + high-frequency vibration de-icing" until it reaches the end of the operation.

[0040] Upon reaching the destination, the remote control system sequentially sends commands to "Stop high-frequency vibration device" and "Stop drive motor 23." After all components have come to a complete stop, a "Power off" command is sent to cut off the device's power supply. The device is then lifted off the power line using a drone and transported to a safe area for cleaning and maintenance.

[0041] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
