Description

Technical Field

[0001] The invention relates to the technical field of line deicing, in particular to a deicing device for a power transmission line. Background Art

[0002] Under the special weather conditions of winter with rain, fog, high humidity and low temperature, transmission lines are very easy to freeze, which increases the load on the cables and easily causes the connections between the cables and the towers to loosen and break, which will have a certain impact on the safe and stable operation of the high-voltage transmission system. Therefore, effective measures must be taken to remove the ice.

[0003] With the development of science and technology, cable de-icing technology has developed rapidly, from manual de-icing to de-icing robots. Compared with manual de-icing, robot de-icing is safer and can walk on the cables to complete comprehensive de-icing. The current common robot de-icing method is usually to load a de-icing wheel on the robot, and crush the ice on the cable by rotating the de-icing wheel to complete de-icing, or to de-icing by impact.

[0004] In summary, these are two common robot de-icing methods. However, for the above de-icing method, although the thin ice on the cable can be easily broken, when the freezing situation is serious and a thicker ice layer is formed on the cable, it is difficult to make the ice fall off by knocking, and the de-icing wheel crushing method is also difficult to break the thick ice layer in time, resulting in poor de-icing effect.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment 1:

[0031] See also Figures 1 to 6 The present invention provides a technical solution: a power transmission line deicing device, comprising a first main frame 1, a first electric telescopic rod 11, a second main frame 12, a first driven frame 13, a second driven frame 14 and a third driven frame 15, wherein the first electric telescopic rod 11 is fixedly mounted on one side of the first main frame 1, the second main frame 12 is fixedly mounted on the output shaft of the first electric telescopic rod 11, one end of the first main frame 1 and the second main frame 12 are both movably mounted with the first driven frame 13, and one end of the first driven frame 13 away from the first main frame 1 or the second main frame 12 is movably mounted with the second driven frame 13 A driven frame 14, a third driven frame 15 is movably mounted on one end of the second driven frame 14 away from the first driven frame 13, a mounting plate 16 is fixedly mounted on the first main frame 1 and the third driven frame 15 below the first main frame 1, a second electric telescopic rod 17 is mounted on the back of the mounting plate 16, a driving arm 18 is movably mounted on the output shaft of the second electric telescopic rod 17, and one end of the driving arm 18 away from the second electric telescopic rod 17 is movably mounted on the surface of the first driven frame 13, and a covering component is arranged at the lower ends of the first main frame 1, the second main frame 12 and the first driven frame 13;

[0032] The covering assembly includes a mounting base 2, the number of the mounting bases 2 is four, and they are movably mounted on the lower ends of the first main frame 1, the second main frame 12 and the two first driven frames 13, respectively. A fixing frame 21 is fixedly mounted on one side of the mounting base 2, a support column 22 is fixedly mounted on the inner side of the fixing frame 21, a limit block 23 is fixedly mounted on one end of the support column 22 away from the fixing frame 21, a limit spring 24 is sleeved on the outer surface of the fixing frame 21, a mounting member 25 is movably mounted on the outer surface of the fixing frame 21, and a first driving groove 26 adapted to the limit block 23 is opened inside the mounting member 25;

[0033] The mounting member 25 is movably mounted inside the mounting base 2, a covering member 27 is fixedly mounted on one end of the mounting member 25 away from the mounting base 2, a ratchet 28 is arranged on the surface of the covering member 27, a covering plate 29 is hingedly mounted on the surface of the mounting base 2, and a positioning member 210 is movably mounted on one end of the covering plate 29 away from the mounting base 2;

[0034] One end of the limit spring 24 is fixedly connected to the inner side of the fixed frame 21, and one end of the limit spring 24 away from the fixed frame 21 is fixedly connected to the mounting member 25, and the diameter of the limit block 23 is larger than the diameter of the support column 22;

[0035] The positioning member 210 is T-shaped, a slide groove 211 matching the positioning member 210 is provided inside the covering member 27, and the covering plate 29 is inclined;

[0036] The ratchet 28 is in the shape of a right triangle, and its inclined surface faces the de-icing direction of the first main frame 1, and the covering member 27 is made of rubber;

[0037] An ice shaving assembly is disposed on one side of the mounting base 2, and the ice shaving assembly is used to improve ice breaking efficiency.

[0038] Specifically, before use, first install a power pack, such as a power battery, on the device, and use a wire to electrically connect the power pack to the power source on the device, then use a drone to transport the device to the frozen cable, so that the cable is in the middle of the covering 27, and then use a controller to start the first electric telescopic rod 11 to drive the second main frame 12 to move, so that the ratchet teeth 28 on the front and rear sides contact the frozen cable;

[0039] As the first electric telescopic rod 11 continues to contract, the frozen cable will be in close contact with the ratchet 28, so that the mounting member 25 squeezes the limit spring 24, so that the mounting member 25 moves. When the mounting member 25 moves, the distance between the covering member 27 and the mounting base 2 becomes smaller, and then the covering plate 29 tilts upward, and the positioning member 210 slides inside the slide groove 211, so that the shape of the covering member 27 changes, so as to cover the frozen cable, and make the ratchet 28 slightly embedded in the ice layer, so as to cover cables with ice layers of different diameters, thereby improving the versatility of the device.

[0040] After the covering member 27 covers the frozen cable, the step of installing the device on the cable is completed. Then, the second electric telescopic rod 17 is started by the controller, so that the driving arm 18 is driven when the second electric telescopic rod 17 is retracted. At this time, the driving arm 18 drives the first driven frame 13, so that the first driven frame 13 on the side where the sleeve 5 is installed is retracted, and the second electric telescopic rod 17 is driven again after the retraction is completed, so that the driving arm 18 drives the first driven frame 13 on the side where the sleeve 5 is installed again. Due to the existence of the ratchet 28, the ratchet 28 on the side close to the fixed plate 34 is subject to less resistance, while the ratchet 28 on the side close to the sleeve 5 is subject to greater resistance. Therefore, the first driven frame 13 on the side where the sleeve 5 is installed is fixed due to the greater friction with the ice layer, and the first driven frame 13 on the side close to the fixed plate 34 will move in the ice-breaking direction, thereby realizing comprehensive de-icing of the cable.

[0041] When the device moves, the ratchet 28 will scratch the surface of the ice layer, making the device move more stably and facilitating the subsequent breaking of the ice layer. It should be noted that the ratchet 28 close to the fixed plate 34 can be made of hard metal such as aluminum alloy, while the ratchet 28 close to the sleeve 5 can be made of plastic or rubber, and during manufacturing, the inclined surface is sharp and the right-angled edge is wide and thick to prevent the ratchet 28 close to the sleeve 5 side from causing wear to the cable after breaking the ice, and the friction between the ratchet 28 on both sides and the ice layer can be adjusted by changing the number of ratchet 28, as long as the device can move smoothly on the cable.

[0042] It should be noted that the controller used in the present invention can be a remote control. When in use, with the help of the camera component on the drone, the combination of the ratchet 28 on both sides and the icing cable can be seen, so that the first electric telescopic rod 11 and the second electric telescopic rod 17 can be better controlled through the controller. As for drones and camera components on drones, they are relatively mature technologies in the prior art and will not be elaborated on here.

[0043] Embodiment 2:

[0044] See also Figure 1, Figure 2 and Figure 7 The ice shaving assembly includes a fixing member 3, which is fixedly installed on one side of the mounting base 2. A closing column 31 is fixedly installed on the surface of the front fixing member 3, a through hole matched with the closing column 31 is opened on the surface of the rear fixing member 3, an elastic pad 32 is fixedly installed on the inner side of the fixing member 3, an ice scraper 33 is fixedly installed on the side of the elastic pad 32 away from the fixing member 3, a fixing plate 34 is fixedly installed on the surface of the front fixing member 3, a motor 35 is fixedly installed on the upper surface of the fixing plate 34, and an ice crusher 36 is fixedly installed on the output shaft of the motor 35.

[0045] When the cables are severely frozen, not only will the thickness of the ice layer increase, but also ice cones will be formed at the bottom of the cables. The presence of ice cones will hinder the movement of the de-icing robot and affect the de-icing efficiency of the de-icing robot.

[0046] On the basis of Example 1, when the first electric telescopic rod 11 is driven to retract, the fixing members 3 on the front and rear sides will approach each other, and the closing column 31 will penetrate the fixing member 3 on the rear side, so that a closed space is formed between the fixing member 3 and the closing column 31, and the cable is placed therein, which can prevent the device from falling when the device covering member 27 falls off the ice layer, thereby improving the safety of the device in high-altitude operation;

[0047] When the first electric telescopic rod 11 is retracted, the ice scraper 33 first contacts the cable. When the covering member 27 has finished covering the cable, the tip of the ice scraper 33 will be embedded in the ice layer. As the device moves, the two sides of the ice layer will be thinned, which is convenient for subsequent ice breaking operations.

[0048] By starting the motor 35, the ice crusher 36 can be driven to break the ice cones first, which can prevent the ice cones from hindering the movement of the equipment. At the same time, since the ice cones at the bottom of the ice layer are destroyed, the ice is brittle and integrated, which will cause the overall structure of the ice layer to break, facilitating subsequent ice breaking operations.

[0049] Embodiment 3:

[0050] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 An ice-breaking assembly is provided on the mounting plate 16, and the ice-breaking assembly includes an extension plate 4, which is fixedly mounted on one side of the mounting plate 16, and an ice-breaking member 41 is fixedly mounted on one end of the extension plate 4 away from the mounting plate 16, and ice-breaking members 42 are fixedly mounted on both sides of the ice-breaking member 41;

[0051] The width of the ice-breaking member 42 is greater than the width of the ice-breaking member 41 , and the height of the ice-breaking member 41 is greater than the height of the ice-breaking member 42 .

[0052] On the basis of Example 1, when the device is moving, the first main frame 1 and the second main frame 12 are in an up and down reciprocating motion state. When the first main frame 1 and the second main frame 12 are close to each other, the upper and lower ice-breaking members 41 are also close to each other, so that the upper and lower ice-breaking members 41 cut off the ice layer. In combination with the ice-crushing member 36 in Example 2 to destroy the integrity of the ice layer, the ice-breaking member 41 can also cut off the ice layer more smoothly.

[0053] When the ice layer is cut off, the ice-breaking member 41 will continue to move downward until it contacts the cable itself, and in this process, the ice-breaking member 42 will press the cut-off ice layer to break the ice layer. Compared with the traditional de-icing wheel de-icing method, it is difficult to flexibly target ice layers of different thicknesses, which leads to the problem of dead corners in de-icing. The crushing and breaking ice method adopted by the present invention can be applied to ice layers of different thicknesses and make de-icing more complete.

[0054] Furthermore, since the surface of the ice layer is relatively smooth, when the ice breaking member 42 presses the ice layer, relative sliding may occur between the ice layer and the ice layer, affecting the ice breaking efficiency. On the basis of Example 1, the scratches on the surface of the ice layer caused by the ratchet 28 will increase the friction between the ice breaking member 42 and the ice layer, reduce the probability of relative sliding between the ratchet 28 and the ice layer, improve the ice breaking efficiency, and make the ice breaking operation smoother.

[0055] Furthermore, if the ice layer is intact or has a relatively uniform thickness, the pressure generated by the ice-breaking element 42 will be applied to the entire ice layer more evenly, reducing the effect of the pressure, thereby increasing the difficulty of ice breaking. Based on Example 2, the ice-crushing element 36 first destroys the integrity of the ice layer, and then the ice-scraping element 33 weakens the thickness of both sides of the ice layer, reducing the uniformity of the ice layer thickness, which can further reduce the difficulty of ice breaking by the ice-breaking element 42.

[0056] In addition, the two compression points of the two ice-breaking pieces 42 on the ice layer are symmetrically distributed up and down and front and back with the two points of the fixing piece 3 that weaken the ice layer. Therefore, when the ice-breaking pieces 42 are compressing, the weakened parts of the ice layer are easier to break. On the other hand, the ice-breaking pieces 42 cut off the ice layer, further reducing the integrity of the ice layer, thereby making the cut-off ice layer easier to break, further allowing the ice-breaking operation to proceed more smoothly.

[0057] Embodiment 4:

[0058] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 A vibration assembly is provided on the first rear driven frame 13, and the vibration assembly includes a sleeve 5, which is fixedly installed on the inner side of the first rear driven frame 13, and an elastic column 51 is installed inside the sleeve 5, and a counterweight block 52 is fixedly installed at the bottom of the elastic column 51.

[0059] On the basis of Example 3, when the device is moving, in addition to the up and down reciprocating motion of the first main frame 1 and the second main frame 12, the two first driven frames 13 are also in an up and down reciprocating motion state, so that the counterweight block 52 also reciprocates up and down, and under the influence of the gravity and inertia of the counterweight block 52, the elastic column 51 will be continuously stretched by the counterweight block 52, and its elastic force will restore the deformation, so that the up and down reciprocating frequency of the counterweight block 52 is greater, and when it contacts the cable, it will cause the cable to vibrate, so that the ice chips that may remain on the cable after the ice breaker 42 breaks the ice will be shaken off, further improving the deicing effect of the device;

[0060] Furthermore, the ice scraper 33 near the side of the sleeve 5 can be made of rubber to prevent it from causing wear to the cable after the ice is broken. In addition, under the elastic force of the elastic pad 32, even if the diameter of the cable after the ice is broken is reduced compared to the cable covered with ice, the ice scraper 33 near the side of the sleeve 5 can be in contact with the cable, so that during the movement of the equipment, the ice chips remaining on the surface of the cable can be further removed, thereby improving the de-icing effect of the equipment.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
