Description

Technical Field

[0001] This utility model relates to the field of cable de-icing technology, and in particular to an overhead cable de-icing device. Background Technology

[0002] Ice accumulation on high-voltage transmission lines is usually caused by weather conditions such as rime, hoarfrost, or freezing rain. These ice layers can cause phase-to-phase flashovers in the lines. Moreover, when the weight of the ice layer exceeds the load-bearing limit of the transmission line, it may cause the high-voltage line to break or even the power tower to collapse, seriously threatening the safety of the power system.

[0003] Currently, de-icing work mainly relies on workers climbing transmission towers to manually knock the ice down. This method is not only labor-intensive and inefficient, but also carries the risk of tower collapse or workers falling to their deaths. Some methods use high-current thermal de-icing, which has a higher de-icing efficiency. However, this method consumes a lot of energy, is very complex to operate, and requires power outages on the transmission lines. It is difficult to use DC de-icing on transmission lines. In addition, some methods use a hoisting mechanism to hang de-icing robots on the cables. As the de-icing robot moves, it crushes the ice on the cables. However, some of the crushed ice may remain on the upper side of the cable and cannot fall off, thus reducing the de-icing effect. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-10 This utility model provides a technical solution: an overhead cable de-icing device, including a frame 1, a walking mechanism 2 and a de-icing mechanism 3, characterized in that: the de-icing mechanism 3 is located in the middle of the walking mechanism 2, and includes two symmetrically arranged tracked ice-grinding components 301 and a spacing adjustment component 302 for adjusting the distance between one end of the two tracked ice-grinding components 301, the other end of the two tracked ice-grinding components 301 is rotatably connected to the frame 1, and a de-icing channel 4 for the cable to pass through is formed between the two tracked ice-grinding components 301, and a cleaning mechanism 5 is connected to the rear side of the frame 1;

[0031] The spacing between one end of the two tracked ice-crushing components 301 is adjusted by the spacing adjustment component 302, so that the two tracked ice-crushing components 301 clamp the iced cable in a figure-eight structure. The overhead cable de-icing device is moved forward along the cable by the driving walking mechanism 2. The tracked ice-crushing components 301 crush the ice on the cable while moving, which improves the degree of automation and the de-icing efficiency. The crushed ice is swept off the top of the cable by the cleaning mechanism 5, so that the ice is completely removed, thereby improving the de-icing effect.

[0032] In order to facilitate the crushing and breaking of ice on the cable and improve the de-icing efficiency, in this embodiment, preferably, the tracked ice crushing assembly 301 includes a swing frame 3011, a rotary track 3012 and a first motor 3013 for driving the rotary track 3012 to rotate. The rotary track 3012 is installed on the lower side of the swing frame 3011 and has a number of ice-breaking teeth 3014 evenly arranged on its outer side.

[0033] The spacing adjustment assembly 302 includes a guide rod 3021, a bidirectional lead screw 3022, and a second motor 3023 that is drivenly connected to the bidirectional lead screw 3022. The bidirectional lead screw 3022 is rotatably connected to the frame 1 and is connected to two nut blocks 3024 by positive and negative threads. The nut blocks 3024 are slidably connected to the guide rod 3021. The guide rod 3021 is fixed to the frame 1. One end of the swing frame 3011 is provided with a relief groove 3015. The nut blocks 3024 are set in the relief groove 3015. The upper and lower sides of the relief groove 3015 are provided with sliding grooves 3016. The upper and lower sides of the nut blocks 3024 are connected with bearings 3025. The two bearings 3025 are slidably connected in the two sliding grooves 3016 respectively. The other end of the swing frame 3011 is rotatably connected to the frame 1.

[0034] The purpose is to increase the distance between one end of the two tracked ice-gripping components 301 when the cable needs to be hung, using the spacing adjustment component 302 to make the two tracked ice-gripping components 301 parallel to each other. This ensures that the width of the de-icing channel 4 is greater than that of the ice-covered cable, allowing the ice-covered cable to enter the de-icing channel 4. Then, the walking mechanism 2 is hung on the ice-covered cable. After the cable is hung, the second motor 3023 drives the bidirectional lead screw 3022 to rotate, which in turn drives the two nut blocks 3024 to move in opposite directions along the guide rod 3021. At the same time, the bearing 3025 moves along the slide groove 3. 016 Slides and pushes the swing frame 3011 to swing, so that the two swing frames 3011 swing into a figure-eight structure, thereby adjusting the distance between one end of the two rotary tracks 3012 to be slightly larger than the diameter of the bare cable. After the adjustment is completed, the overhead cable de-icing device is driven to move forward along the cable through the walking mechanism 2. At the same time, the rotary track 3012 is driven to rotate through the first motor 3013, so that the rotary track 3012 moves along the ice layer and uses the ice-breaking teeth 3014 to crush and break the ice layer of the cable, thereby improving the degree of automation and the de-icing efficiency.

[0035] In order to facilitate complete removal of ice and improve the ice removal effect, in this embodiment, preferably, the cleaning mechanism 5 includes a third motor 501, a first mounting frame 502 and a turntable 503. The first mounting frame 502 is fixedly connected to the rear side of the frame 1. The third motor 501 is mounted on the first mounting frame 502, and its bottom output end is connected to the middle of the turntable 503 for transmission. Several brush pieces 504 are arranged in a circular array on the outer side of the turntable 503, and the brush pieces 504 protrude downward from the turntable 503.

[0036] The purpose is to crush the ice on the cable into small pieces through the de-icing mechanism 3, and then drive the turntable 503 to rotate through the third motor 501, which in turn drives multiple brush pieces 504 to rotate along the center of the turntable 503, so that the brush pieces 504 sweep the small pieces of ice off the upper side of the cable, ensuring that the ice is completely removed, thereby improving the ice removal effect.

[0037] To facilitate the replacement of the brush component 504, in this embodiment, preferably, the turntable 503 is arranged in the shape of an inverted frustum, and a number of mounting seats 505 are arranged in a circular array on its outer side. The mounting seat 505 is provided with a T-shaped groove 506 on the side away from the turntable 503. The brush component 504 includes a T-shaped block 5041, a triangular block 5042, and bristles 5043 connected to the bottom of the triangular block 5042. The triangular block 5042 is connected to one side of the T-shaped block 5041, and the T-shaped block 5041 can be detachably snapped into the T-shaped groove 506.

[0038] The purpose is to insert the T-shaped block 5041 obliquely into the T-shaped groove 506 to form a snap-fit ​​fixation of the brush part 504, thereby enabling the quick installation of the brush part 504. The T-shaped block 5041 is then pulled out obliquely from the T-shaped groove 506 to enable the quick disassembly of the brush part 504, thus facilitating the replacement of the brush part 504.

[0039] To improve stability during walking, in this embodiment, preferably, the walking mechanism 2 includes a front walking wheel 201 and a rear walking wheel 202, both of which are rotatably connected to the frame 1 and are respectively located on the front and rear sides of the de-icing mechanism 3.

[0040] The purpose is to place the de-icing mechanism 3 between the front walking wheel 201 and the rear walking wheel 202 to ensure that the center of gravity of the overhead cable de-icing device is centered, thereby improving the stability during movement.

[0041] To make the operation more flexible and improve applicability, in this embodiment, preferably, a hanging assembly 6 is detachably connected to the top of the frame 1. The hanging assembly 6 includes a hanger 601 and an inclined guide frame 602. Hooks 603 are symmetrically connected to the top two sides of the hanger 601, and the two ends of the inclined guide frame 602 are respectively connected to the two hooks 603.

[0042] The purpose is to connect the hanger 601 to the frame 1 and guide it through the inclined guide frame 602, so that the boom of the drone can be hung into the hook 603. Then, the drone can be remotely controlled to lift the overhead cable de-icing device and hang it on the cable, making the operation more flexible and improving its applicability.

[0043] In order to reduce the space occupied by the overhead cable de-icing device during storage or transportation, in this embodiment, preferably, the top of the frame 1 is connected to a second mounting bracket 7, the second mounting bracket 7 is provided with a mounting groove 8, the bottom of the hanger 601 is connected to a plug-in foot 604, the plug-in foot 604 is movably inserted into the mounting groove 8, and the second mounting bracket 7 is detachably connected to a ball-head quick-release pin 9, the ball-head quick-release pin 9 movably passes through the plug-in foot 604;

[0044] The purpose is to allow for quick installation of the hanging assembly 6 when the overhead cable de-icing device is needed. This is achieved by inserting the plug pin 604 of the hanging assembly 6 downwards into the mounting groove 8, then installing the ball-head quick-release pin 9 to pass through the plug pin 604 and secure it. When the overhead cable de-icing device is no longer in use, the ball-head quick-release pin 9 is removed, and the plug pin 604 of the hanging assembly 6 is moved upwards from the mounting groove 8, thus achieving quick disassembly of the hanging assembly 6. This reduces space occupation and facilitates the storage and transportation of the overhead cable de-icing device.

[0045] In order to improve the stability of the overhead cable de-icing device, in this embodiment, preferably, inclined support components 10 are symmetrically connected on both sides of the bottom of the frame 1, one inclined support component 10 is equipped with a battery box 11, and the other inclined support component 10 is equipped with a counterweight 12 corresponding to the weight of the battery box 11.

[0046] The purpose is to provide ground support for the overhead cable de-icing device through the inclined support component 10. When de-icing the cable, the battery box 11 and the counterweight 12 are installed on the inclined support component 10 respectively, so that the center of gravity of the overhead cable de-icing device is lower than the lowest position of the cable. Thus, the overhead cable de-icing device generates a corrective torque when it is tilted by its own weight, ensuring that the overhead cable de-icing device does not tip over and improving the stability of the overhead cable de-icing device.

[0047] In order to reduce the space occupied by the overhead cable de-icing device during storage or transportation, in this embodiment, preferably, the inclined support assembly 10 includes a first support leg 1001 and a second support leg 1002. One side between the first support leg 1001 and the second support leg 1002 is hinged by a hinge 13, and the adjacent side is movably fastened by a latch 14.

[0048] The purpose is to unlock the latch 14 when the overhead cable de-icing device is no longer in use, and then flip the second support leg 1002 upward with the hinge 13 as the center, so that the first support leg 1001 and the second support leg 1002 are in a folded state, which reduces the space occupied and facilitates the storage and transportation of the overhead cable de-icing device. When the overhead cable de-icing device needs to be used, flip the second support leg 1002 downward with the hinge 13 as the center, so that the first support leg 1001 and the second support leg 1002 are in an unfolded state, and then lock the latch 14 to fix it.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
