Description

Technical Field

[0001] The present invention relates to the field of cable deicing technology, in particular to a torsional ultrasonic cable deicing technology and device. Background Art

[0002] Cables are widely used in many fields such as power transmission and communications, and most of them are installed in outdoor environments. In cold weather conditions, especially in areas with high humidity, low temperature, and severe snow and ice, ice is easily attached to the surface of cables. The accumulation of these ice layers will bring many serious problems, such as significantly increasing the extra weight of the cables, causing the cables to sag or even break, and seriously affecting the stability and reliability of power supply and communication transmission. This will not only cause great inconvenience to people's daily life and production activities, but also cause a series of safety accidents, such as production interruptions caused by power outages, and communication interruptions affecting emergency rescue. Therefore, the research and development of cable deicing technology and equipment is crucial to ensure the normal operation of infrastructure.

[0003] Existing cable deicing technologies and devices use a variety of methods. In terms of mechanical deicing, it is common to use manual or mechanical force to knock or scrape the ice layer on the surface of the cable. For example, a long-pole tool is used to knock the cable manually, or a mechanical arm mounted on a vehicle carries an ice scraper and moves along the cable to scrape the ice. Although this method can directly remove the ice layer, it is easy to cause damage to the cable body, such as scratching the cable sheath, affecting the insulation performance and service life of the cable. There are also some methods that use heating to de-ice, such as wrapping a heating wire around the cable or using hot air blowing. However, heating deicing has the problems of high energy consumption and low deicing efficiency. When deicing long-distance cables, the cost is high and the effect is not ideal. In addition, some chemical deicers have also been tried, but chemical deicers can cause corrosion to cables and the surrounding environment and other adverse effects.

[0004] Taking the deicing of power transmission cables in mountainous areas as an example, the existing technologies face many difficulties in severe winter weather. For the mechanical knocking deicing method, in mountainous areas with complex terrain, it is difficult for manual operation to reach all cable positions, and the knocking force is not easy to control, which can easily damage the cables. When using a mechanical arm to scrape ice, due to the height of the cable installation and the complex terrain, the operating flexibility of the mechanical arm is limited, and it is difficult to accurately scrape ice along the cable, resulting in incomplete deicing, and some residual ice will still affect the performance of the cable. In terms of heating deicing, the power supply conditions in mountainous areas are limited, and the high-energy consumption heating method is difficult to continue, and the heating is uneven. Some ice layers close to the heating source melt first, and the parts far away remain frozen, and efficient and comprehensive deicing cannot be achieved. Compared with the beneficial effects of efficient deicing operations, the existing technology cannot quickly and evenly remove the ice layer on the surface of the cable, affecting the normal operation of the cable. In terms of convenient operation and maintenance, the existing deicing devices are often large in size and complex in structure. If a deicing device is used on a vehicle, a special transportation and operation site is required, which is difficult to use in special terrains such as mountainous areas. Moreover, the components of these devices are inconvenient to install and disassemble. Once a fault occurs, maintenance is difficult and time-consuming. In daily maintenance, due to the complex structure, it is difficult to regularly inspect and maintain key components, which reduces the reliability and service life of the device. It cannot be operated and maintained as conveniently as new devices, which increases the difficulty and cost of deicing. Therefore, the present invention provides a torsional ultrasonic cable deicing technology and device to solve the deficiencies in the prior art. Summary of the invention

[0026] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] Please see attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides a torsional ultrasonic cable deicing device, including a mounting frame 1, which is used as a basic component of the overall device for assembling and carrying various processing mechanisms and their subordinate structural members; a cable 12, which is located on the inner side of the mounting frame 1 and is used as an object of deicing operation; a walking mechanism, which is arranged on the outer side of the mounting frame 1 and is used for moving the overall device; a deicing mechanism, which is arranged on the inner side of the mounting frame 1, and includes two ultrasonic generators 13, which are respectively installed on both sides of the interior of the mounting frame 1, and a conversion rod 14 is installed at the output end of the ultrasonic generator 13, and a coupling clamp 15 is sleeved on the outside of the cable 12, and the outer side of the conversion rod 14 is in contact with the outer side of the coupling clamp 15.

[0029] Specifically, the mounting frame 1 is usually made of a strong and corrosion-resistant metal material, and its structural design is reasonable, with sufficient strength and stability. As the basic component of the overall device, it provides a reliable assembly and bearing platform for each processing mechanism and its subordinate structural parts. In practical applications, the size and shape of the mounting frame 1 are designed according to the specifications and usage scenarios of the cable 12 to ensure that it can perfectly cooperate with other components to achieve efficient deicing operations. As the object of deicing operation, the cable 12 plays a vital role in the fields of power transmission, communication, etc. However, in cold weather or under specific conditions, ice is easily attached to the surface of the cable 12, which not only increases the weight of the cable 12, but also affects its transmission performance, and even causes damage to the cable 12. Therefore, the deicing work of the cable 12 is of great significance. The walking mechanism is arranged on the outside of the mounting frame 1, and is used for the movement of the overall device on the cable 12. The walking mechanism includes a driving component and a driven component, which work together to ensure that the device can move smoothly and efficiently on the cable 12. The deicing mechanism is arranged on the inside of the mounting frame 1, and the deicing mechanism includes two ultrasonic generators 13. Two ultrasonic generators 13 are precisely mounted on both sides of the interior of the mounting frame 1. The ultrasonic generator 13 adopts advanced ultrasonic generation technology and can generate high-frequency and high-intensity ultrasonic signals. A conversion rod 14 is installed at the output end of the ultrasonic generator 13. The material and structure of the conversion rod 14 can effectively convert the ultrasonic signal generated by the ultrasonic generator 13 into a torsional wave suitable for deicing. The outer sleeve of the cable 12 is provided with a coupling clamp 15. The material of the coupling clamp 15 is selected from materials with good acoustic properties, which can effectively couple the torsional wave generated by the conversion rod 14 to the cable 12. The outer side of the conversion rod 14 fits with the outer side of the coupling clamp 15 to ensure that the torsional wave can be efficiently transmitted to the cable 12, so that the ice attached to the surface of the cable 12 is broken under the action of the torsional wave, thereby achieving the deicing effect.

[0030] Please see attached Figure 1 -Attached Figure 4The walking mechanism includes a driving component and a driven component. The driving component is arranged on the outside of the installation frame 1. The driving component includes a mounting plate 2 and a motor 3. The mounting plate 2 is fixedly connected to the outside of the installation frame 1. The motor 3 is installed on the outside of the mounting plate 2. Both sides of the outside of the installation frame 1 are rotatably connected with a driving shaft 4. The outside of the driving shaft 4 is fixedly connected with a driving gear 5. The output end of the motor 3 is fixedly connected to one end of one of the driving shafts 4. The driven component includes a roller 6, which is rotatably connected to the inside of the installation frame 1. Both ends of the roller 6 penetrate the outer wall of the installation frame 1 and are fixed. A driven gear 8 is connected, and the driven gear 8 is meshed with the driving gear 5. Two disassembly handles 9 are detachably connected to the inner side of the mounting frame 1. The inner side of the disassembly handle 9 is rotatably connected with a roller 2 7. Both sides of the outer side of the disassembly handle 9 close to the roller 1 6 are rotatably connected with driven gears 8, and the upper and lower driven gears 8 are meshed. Two guide rails 11 are fixedly connected to the inner side of the mounting frame 1, and a support seat 10 is fixedly connected to the movable seats of the two guide rails 11. The bottom of the support seat 10 is in contact with the outer side of the cable 12, and the outer sides of the two rollers 2 7 are in contact with the outer side of the cable 12.

[0031] Specifically, the drive assembly is arranged on the outside of the installation frame 1, and the drive assembly includes a mounting plate 2 and a motor 3. The mounting plate 2 is firmly fixedly connected to the outside of the installation frame 1, providing a stable installation foundation for the motor 3. The material of the mounting plate 2 is compatible with the installation frame 1, and has good load-bearing capacity and corrosion resistance. The motor 3 is installed on the outside of the mounting plate 2. The motor 3 adopts a high-performance, low-energy motor 3, and its output power and speed can meet the needs of the device moving on the cable 12. Both sides of the outside of the installation frame 1 are rotatably connected with a drive shaft 4 through precision bearings. The material of the drive shaft 4 is selected from high-strength alloy steel, which has good wear resistance and rigidity. The outside of the drive shaft 4 is fixedly connected with a driving gear 5. The number of teeth and the module of the driving gear 5 are designed according to the transmission ratio requirements to ensure accurate and smooth meshing with the driven gear 8. The output end of the motor 3 is fixedly connected to one end of one of the drive shafts 4. When the motor 3 is started, it can drive the drive shaft 4 to rotate stably. The driven assembly includes a roller 16, which is rotatably connected to the inner side of the mounting frame 1 through a high-quality bearing. The material of the roller 16 is usually a material with good anti-slip properties such as rubber or polyurethane, which can effectively contact the surface of the cable 12, provide sufficient friction, and push the device to move on the cable 12. The two ends of the roller 16 accurately penetrate the outer wall of the mounting frame 1 and are fixedly connected with a driven gear 8. The design of the driven gear 8 matches the driving gear 5, ensuring that when the driving gear 5 rotates, it can accurately drive the driven gear 8 to rotate, thereby realizing the rotation of the roller 16. The outer sides of the disassembly handle 9 close to the roller 16 are rotatably connected with the driven gear 8, and the upper and lower driven gears 8 are meshed. This meshing method ensures the stable transmission of power, so that the roller 2 7 can rotate synchronously with the roller 16. Two guide rails 11 are fixedly connected to the inner side of the mounting frame 1. The structure of the guide rails 11 is reasonably designed and can provide a stable moving track for the support seat 10. The support base 10 is firmly fixed to the moving base of the two guide rails 11, and the bottom of the support base 10 contacts the outside of the cable 12. The shape and material of the support base 10 are designed according to the shape and surface characteristics of the cable 12, which can provide stable support for the device without causing damage to the cable 12. The outer sides of the two rollers 2 7 contact the outer sides of the cable 12. The material and performance of the rollers 2 7 are similar to those of the rollers 1 6, and they act together on the cable 12 to ensure the stable movement of the device on the cable 12.

[0033] The torsional ultrasonic cable deicing method comprises the following steps;

[0034] S1, start two ultrasonic generators 13 to emit torsional waves to input to the cable 12 for de-icing;

[0035] S2, starting the walking mechanism to move the installation frame 1 to remove ice from the surface of the cable 12.

[0036] Working principle: First, hang the entire device on the cable 12 so that the two rollers 2 7 are in contact with the cable 12, start the motor 3 to drive the drive shaft 4 to rotate, thereby driving the active gear 5 to rotate, and then the driven gear 8 to rotate, so that the rollers 2 7 and roller 1 6 will move the cable 12 to move, and at the same time start the two ultrasonic generators 13 and the coupling hoop 15 to cooperate to generate a torsional wave to twist the cable 12, so that the ice attached to the surface of the cable 12 is broken to achieve the de-icing effect. Under the continuous movement of the installation frame 1, all the ice on the surface of the entire cable 12 can be removed. When the de-icing device is not in use, the rollers 1 6 and rollers 2 7 can be disassembled, so that the entire device can be removed from the cable 12.
