Description

Technical Field

[0001] This invention relates to the field of high-altitude cable maintenance technology, and in particular to a portable high-altitude cable maintenance device. Background Technology

[0002] After a blizzard in winter, thick layers of ice easily form around high-altitude power cables, reducing their power transmission efficiency. If not removed for a long time, this can cause the cables to collapse and break under the weight, resulting in serious economic losses. Current technology relies on drones carrying vibration or flamethrower equipment to remove the ice, a process requiring frequent and complex drone operations. Another method involves cable inspection robots walking on the cables and crushing the ice on the surface. However, even after crushing the ice, some ice residue remains, leading to incomplete cleaning. When a cable inspection robot crushes ice on a cable, ice residue adheres to the crushed structure, affecting its subsequent operational efficiency. Furthermore, without further antifreeze measures after de-icing, ice can easily refrozen and form again.

[0003] When thick layers of ice and icicles form around the cable, the cable inspection robot's movement along the cable causes vibrations. Ice icicles that are close to the robot and have not yet been crushed are very likely to fall off due to the vibrations. When there is a substation area below the cable, the falling ice can easily land on un-de-iced cables and transformer equipment, causing damage and economic losses. Summary of the Invention

[0010] More preferably, it also includes a crushing component, which includes a third slider; two third slide grooves are symmetrically arranged on the lower side of the housing; a third slider is slidably connected to each third slide groove; two connectors are fixedly connected to the top of the crushing half-chamber, and the connectors are detachably connected to the third sliders, so that the two crushing half-chambers can fit together to form a complete crushing chamber; a second mounting block is provided on the lower side of each crushing half-chamber, and a micro motor is fixedly connected to the second mounting block; a crushing roller for secondary crushing of ice blocks that have fallen from the cable is rotatably connected to the bottom of each crushing half-chamber, and the crushing roller is connected to the output shaft of the micro motor.

[0015] Beneficial effects: This invention achieves the removal of ice by controlling the electric drive wheel to drive the ice-crushing belt to rotate, so that all the ice-crushing teeth move synchronously with the ice-crushing belt. The ice-crushing teeth and the pressing block work together to squeeze and collide with the ice layer on the outer periphery of the cable. The heated protrusion and the ice-breaking cone work together to squeeze and collide with the ice slag adhering to the arc groove, squeezing and briefly heating the ice slag to melt it, and breaking the adhering ice slag through the cone front end, thus softening the adhering ice slag. By colliding the protrusions with the residual ice slag on the arc-shaped groove, the ice slag adhering to the arc-shaped groove is ultimately scraped off by the collision of the protrusions. Antifreeze oil is pumped into the annular sponge through a built-in pump to saturate it. Finally, as the equipment moves forward, the annular sponge applies the antifreeze oil to the outer periphery of the de-iced cable. The crushing chamber collects the uncrushed ice cones that have detached due to vibration and moves them down the slope to the crushing drum for secondary crushing. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Example 1: A portable high-altitude cable inspection and maintenance device, such as... Figures 1-4 As shown, it includes a housing 1, a first roller module 4, a second roller module 5, and a handle 2; the handle 2 is installed on the housing 1; two first sliding grooves 1001 are symmetrically arranged on the lower side of the housing 1; the first roller module 4 is arranged on the front side of the housing 1; and the second roller module 5 is arranged on the rear side of the housing 1. It also includes a first slider 101, a first mounting block 102, an electric drive wheel 103, an ice-crushing toothed belt 104, ice-crushing tooth blocks 105, and a pressing block 106; a first slider 101 is slidably connected to each of the two first sliding grooves 1001; a first mounting block 102 is bolted to the lower side of each first slider 101; two electric drive wheels 103 are symmetrically arranged on the lower side of each first mounting block 102; an ice-crushing toothed belt 104 is arranged on the outer side of the two electric drive wheels 103; a number of ice-crushing tooth blocks 105 are arranged on the outer side of the ice-crushing toothed belt 104; an arc-shaped groove 10501 is provided on each ice-crushing tooth block 105; a number of pressing blocks 106 are arranged in an equidistant array on the arc-shaped groove 10501.

[0020] After heavy snowfalls in winter, thick layers of ice easily form around high-altitude power cables, reducing their power transmission efficiency. If not removed for a long time, the cables may collapse and break under the weight, causing serious economic losses. In current technology, the removal of ice around cables relies on drones carrying vibration or flamethrower equipment. This process requires frequent operation of the drones for high-difficulty tasks. Another method is to use existing cable inspection robots to walk on the cables and crush the solidified ice on the cable surface using a squeezing method. However, even after crushing and removing the ice around the cables, some ice residue may remain, resulting in incomplete cleaning.

[0021] To address the aforementioned issues, when clearing ice from high-altitude cables, workers operate a drone equipped with a hook to lift and transport the device to the cable to be cleared via handle 2. After the first roller module 4 and the second roller module 5 make stable contact with the ice layer around the cable, the first sliders 101 on both sides are controlled to move along the first groove 1001 towards the center of the housing 1, causing the first mounting block 102 to move synchronously towards the cable following the first slider 101. During this process, the ice-crushing teeth 105 move synchronously towards the cable following the first mounting block 102. When the pressing block 106 comes into contact with the ice layer around the cable, it crushes the ice layer around the cable. Finally, the pressing block 106 contacts the cable surface, stabilizing the device on the cable. Compared to existing ice-crushing structures where the ice-crushing teeth 105 on both sides cannot move and thus have a fixed spacing, this device can adapt to ice layers of different thicknesses, allowing the device to stabilize on the cable more quickly. It will not prevent the device from being unable to be placed on the cable due to the ice layer thickness exceeding the spacing of the ice-crushing teeth 105 on both sides.

[0022] Example 2, based on Example 1, such as Figures 5-8 As shown, it also includes an oiling assembly, which includes an oil tank 201, a hose 202, a second slider 203, a hollow annular block 205, a mounting ring 208, a heating wire 2010, a protrusion 2012, a reinforcing rib 2013, an ice-breaking cone 2014, a heat-conducting plate 2015, a protrusion 2016, an annular sponge 2017, an oiler, an elastic element, and a trigger rod; the oil tank 201 is hung on the housing 1; two hoses 202 are symmetrically connected to the lower side of the oil tank 201; two second sliding grooves 3001 are symmetrically arranged on the lower side of the housing 1; a second slider 203 is slidably connected to each second sliding groove 3001; a hollow annular block 205 is bolted to the lower side of each second slider 203; a mounting ring 208 is fixed to the front side of each hollow annular block 205; the inner ring of the mounting ring 208... A heating wire 2010 is provided on the surface; the front side of the heating wire 2010 is bent at equal intervals to form several protrusions 2012; several reinforcing ribs 2013 are arrayed on the outer ring surface of each mounting ring plate 208, and the gap between the reinforcing ribs 2013 and the pressing block 106 is aligned; the position of the reinforcing ribs 2013 corresponds to the protrusions 2012; an ice-breaking cone 2014 is fixedly connected to the front side of each reinforcing rib 2013; a heat-conducting plate 2015 is provided inside each ice-breaking cone 2014; the heat-conducting plate 2015 is in contact with the protrusions 2012; a protrusion 2016 is installed on each reinforcing rib 2013; an annular sponge 2017 is attached to the inner ring surface of each hollow annular block 205; each hollow annular block 205 contains an oil storage tank 20501, and several through holes penetrate the inner ring surface of the hollow annular block 205.

[0023] The mounting ring 208 is made of thermal insulation material to reduce heat loss from the heating wire 2010.

[0024] Each mounting ring 208 has a moisture-absorbing sponge installed on its inner ring surface to absorb the moisture generated after the ice crystals evaporate when heated, preventing it from affecting the subsequent application of antifreeze oil.

[0025] The protrusion 2016 is T-shaped. Through the movement of the protrusion 2016 and the rotation of the ice-crushing teeth 105, the residual ice slag that has been broken and softened by heat and adhered to the arc groove 10501 is scraped off, thereby cleaning the arc groove 10501.

[0026] After the equipment is transported and stabilized on the cable, the second sliders 203 on both sides are controlled to move along the second slide groove 3001 towards the center of the housing 1, driving the hollow annular block 205 to move synchronously towards the cable. During this process, the mounting ring 208 and the heating wire 2010 move synchronously towards the cable along the hollow annular block 205. Then, the first sliders 101 on both sides are controlled to move along the first slide groove 1001 towards the center of the housing 1 to complete the steps before the de-icing work. When the cleaning work is carried out, the power supply of the equipment is controlled to heat the heating wire 2010. At the same time, the protrusion 2012 is heated and conducts heat to the ice-breaking cone 2014 through the heat-conducting plate 2015, so that it has a high temperature.

[0027] Then, the electric drive wheel 103 is activated to drive the ice-crushing tooth block 105 to rotate and control the equipment to move along the cable to clean the ice layer. When an ice-crushing tooth block 105 participates in the crushing work, because it is a crushing method, relatively dense compressed ice slag is very easy to accumulate between the pressing blocks 106 in the arc groove 10501. After crushing and cleaning, a thin layer of ice is very likely to remain on the outer periphery of the cable. When the ice-crushing tooth block 105 moves to pass the mounting ring plate 208 and the heating wire 2010, the heated ice-breaking cone 2 014 passes through the arc-shaped groove 10501 and collides with the dense ice slag accumulated between the pressing blocks 106 in the arc-shaped groove 10501. The ice-breaking cone 2014 can easily penetrate the dense ice slag formed by the compression between the pressing blocks 106 through its own temperature and cone head, so that the adhering ice slag softens. As the ice-breaking tooth block 105 continues to move, the ice slag will further collide with the protrusion 2016, and finally the compressed ice slag accumulated in the arc-shaped groove 10501 is removed by the protrusion 2016.

[0028] Compared to using the protrusion 2016 alone to remove the compressed ice slag between the pressing blocks 106, this equipment first breaks down the overall structure of the compressed ice slag using the heated ice-breaking cone 2014. This significantly reduces the overall strength of the compressed ice, lessens the working pressure on the protrusion 2016, and lowers the probability of equipment damage. During the process, the cable enters the coverage area of ​​the mounting ring 208. Because the mounting ring 208 is made of heat-insulating material, the heat dissipation rate of the heating wire 2010 in the covered area is lower, so that the residual ice layer on the cable is concentratedly heated and eventually melted and removed after passing through this area. This achieves simultaneous cleaning of the cable and the residual ice layer on the crushing equipment, preparing in advance for subsequent cable antifreeze treatment.

[0029] When antifreeze treatment is required for cables after de-icing, the built-in pump in the housing 1 is started to fill the antifreeze oil in the oil storage tank 201 into the oil storage tank 20501 through the hose 202. Then, the hollow annular block 205 drives the annular sponge 2017 to move towards the cable and make it adhere to the cable surface. At this time, the pump pumps the antifreeze oil in the oil storage tank 20501 out through several micro-holes on the inner ring surface of the hollow annular block 205, which wets the annular sponge 2017. Finally, during the forward movement of the equipment, the annular sponge 2017 applies antifreeze oil to the outer periphery of the de-iced cable, thereby achieving antifreeze treatment of the cable and reducing the frequency of cable de-icing.

[0030] Example 3, based on Example 2, such as Figures 9-10 As shown, it also includes a crushing assembly, which includes a third slider 301, a connector 302, a crushing half-chamber 303, a trapezoidal cover 304, a second mounting block 305, and a crushing roller 306; two third slide grooves 1002 are symmetrically arranged on the lower side of the housing 1; a third slider 301 is slidably connected to each third slide groove 1002; two connectors 302 are welded to the top of the crushing half-chamber 303, and the connectors 302 are detachably connected to the third sliders 301, and the two crushing half-chambers 303 can be fitted together to form a complete crushing chamber; a second mounting block 305 is provided on the lower side of each crushing half-chamber 303, and a micro motor is bolted to the second mounting block 305; a crushing roller 306 is rotatably connected to the bottom of each crushing half-chamber 303, and the crushing roller 306 is connected to the output shaft of the micro motor.

[0031] Each crushing half-chamber 303 is designed in the shape of an inverted frustum, so that ice blocks that fall off due to vibration during cable de-icing enter the crushing half-chamber 303 and converge towards the crushing drum 306 for secondary crushing.

[0032] Each crushing chamber 303 is equipped with a trapezoidal cover 304 on its front side to prevent ice from splashing onto the outside of the crushing chamber 303 during cable de-icing.

[0033] Each crushing drum 306 is equipped with an array of several protruding round rods to further crush falling ice blocks.

[0034] The inner surface of the crushing chamber 303 is coated with an anti-icing coating to prevent surface icing, which would increase the weight of the crushing chamber 303 and prevent ice falling into the crushing chamber 303 from sliding and accumulating at the crushing drum 306.

[0035] When a thick layer of ice or icicles forms on the outer perimeter of a cable, the cable inspection robot's movement on the cable causes vibrations. Ice icicles that are close to the robot and have not yet been crushed are very likely to fall off due to the vibrations. When there is a substation area below the cable, the falling ice icicles are likely to fall onto un-de-iced cables and transformer equipment, causing damage and economic losses.

[0036] To address the aforementioned issues, when the equipment is de-icing, the two third sliders 301 are controlled to move along the third chute 1002 towards the center of the housing 1, causing the two crushing chambers 303 to move relative to each other and close together. Subsequently, the crushing drum 306 is activated. As the equipment performs de-icing work and moves along the cable, causing cable vibration, ice cones that are close to the cable inspection robot and have not yet been crushed will fall directly due to the vibration. The fallen ice cones will then fall downwards into the crushing chamber 303 and move downwards along the slope to the crushing drum 306. The crushing drum 306 will crush the fallen ice cones into ice slag, which will then be discharged from below the crushing chamber 303. This achieves the crushing treatment of the fallen, uncrushed ice cones, preventing the falling ice cones from falling onto the cables and transformer equipment below and causing damage and economic losses, thus protecting the equipment below the cables.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
