Description

Technical Field

[0001] The present invention relates to the technical field of cable maintenance, and in particular to a device and method for live deicing of lines. Background Art

[0002] Icing not only increases the weight of power lines, placing greater strain on them, but can also cause a sharp decline in electrical performance, leading to problems such as line overload, ice flash, and ice galloping. Therefore, line de-icing technology has become a key component in ensuring the safe and stable operation of power systems.

[0003] Currently, deicing technology for power lines operating during power outages is mature, with DC ice melting and robotic deicing technologies both well-established and widely used in power grids. However, the widespread and complex impact of the 2024 freezing rain, the most severe since 2008, means that existing deicing methods still have drawbacks. However, if ice can be removed from lines during the early to mid-stage of light ice accumulation, the risk of power outages can be significantly reduced. Therefore, if live deicing equipment can be used while the lines are operating, the impact of ice accumulation will be less likely to exceed the tolerance of the lines. Therefore, we propose a device and method for live deicing of power lines to address this issue. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a device and method for live deicing of lines.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

The outer walls of the two assembly plates are provided with two sliding holes, and the inner walls of the two sliding holes are slidably connected to a sliding rod. The spring is sleeved on the outer wall of the sliding rod, and a nut is threadedly sleeved on the top outer wall of the sliding rod. The outer wall of the wire clamping groove is fixedly connected to the top outer wall of the connecting rod, and the bottom of the telescopic rod is fixedly connected to the top of the wire clamping groove, and the outer wall of the collar is slidably connected to the hook. When the collar is subjected to tension, the telescopic rod is stretched, and the telescopic rod pulls the traction rope, and the traction rope passes around the movable pulley group and the fixed pulley group. When subjected to force, the movable pulley group can be pulled to move up and down relative to the fixed pulley group.

[0009] Preferably, both ends of the spring are in contact with the outer walls of the two assembly plates respectively. When the movable pulley group moves up and down relative to the fixed pulley group, it drives the connecting rod to move up and down, causing it to disengage or press the ice-breaking head and compress or stretch the spring.

[0012] Preferably, the suspension assembly includes a motor, the outer wall of the drone body is provided with a groove and a rectangular delivery slot, the inner wall of the groove is fixedly connected to the outer wall of the motor, one end of the motor output shaft is fixedly connected to a conical block, the outer wall of the conical block is fixedly connected to a rectangular block, the outer wall of the conical block is provided with a hanging ring, the bottom of the hanging ring is fixedly connected to a pull rope, the bottom of the pull rope is fixedly connected to the top of the hook, and the provision of the conical block and the rectangular block makes it easy to limit the hanging ring on the drone body and facilitates subsequent disassembly.

[0013] Preferably, a through hole is formed on the inner wall of the groove, and the inner wall of the through hole is rotatably connected to the outer wall of the motor output shaft.

[0014] Preferably, the conical block and the rectangular block are located in a rectangular delivery trough, and the hanging ring is located on one side of the rectangular block.

[0015] Preferably, two tripods are installed at the bottom of the drone body, and the drone body is supported by the tripods.

[0018] S2. Place the hook on the suspension assembly, and then stand up the mounting assembly and the de-icing assembly;

[0019] S3: The drone takes off via the remote control device. The suspension assembly gradually rises until the drone leaves the ground. The spring is compressed by the weight, and the icebreaker head separates from the cable slot.

[0020] S4. Move the device close to the line so that the line is clamped between the ice-breaking head and the clamping groove. The drone body drives the suspension assembly to gradually descend, so that the clamping groove and the ice-breaking head clamp the line.

[0021] S5. The power assembly is triggered, and the piston cylinder transmits vibration to the ice-breaking head and the line to remove ice covering the line.

[0024] By arranging an ice-breaking head, a piston cylinder, a power assembly, a signal transmission device, a wire groove, a slide rod, a guide sleeve and an assembly plate, the piston cylinder transmits vibration to the line between the ice-breaking head and the connecting rod, causing the line to vibrate at high frequency, thereby removing ice from the line. This enables remote de-icing, requires fewer operators, saves time, and has a good de-icing effect, without the need for power outages.

[0025] By setting grooves, rectangular delivery troughs, motors, conical blocks, rectangular blocks, lifting rings and pull ropes, it is convenient to hang the mounting components and de-icing components on the drone body, and the equipment is driven into the air by the drone body to facilitate de-icing of the line.

After the power assembly 23 is triggered, high-speed gas is generated inside, and the vibration is transmitted to the line 3 between the ice-breaking head 21 and the connecting rod 19 through the piston cylinder 22, causing high-frequency vibration of the line 3 to remove the ice covering the line 3. The bottom of the ice-breaking head 21 is fixedly connected to the piston cylinder 22, and the bottom of the piston cylinder 22 is fixedly installed with a power assembly 23.

A wire clamping groove 25 is provided on the top of the ice-breaking head 21, and the line 3 is placed between the wire clamping groove 25 and the ice-breaking head 21.

[0034] The top of the piston cylinder 22 and the bottom of the connecting rod 19 are fixedly sleeved with an assembly plate 28. The outer walls of the fixed pulley group 13 and the movable pulley group 16 are respectively fixedly connected to the outer walls of the two assembly plates 28.

[0035] The top of the piston cylinder 22 passes through the bottom of another assembly plate 28, and the piston cylinder 22 is supported by the ice-breaking head 21.

[0038] A method for deicing a line under electric current includes the following specific steps:

[0039] S1. Prepare the drone body 4 and the remote control device, including the mounting assembly 1 and the de-icing assembly 2, and place them near the line 3 that needs to be de-iced.

[0040] S2. Place the hook 18 on the suspension assembly 17, and then stand up the mounting assembly 1 and the de-icing assembly 2;

[0041] S3, the drone body 4 is driven to take off by the remote control device, and the suspension assembly 17 is gradually raised. When the drone body 4 leaves the ground, the spring 14 is compressed under the action of the weight, and the ice breaking head 21 is separated from the wire clamping groove 25;

[0042] S4. Move the device close to line 3 so that line 3 is clamped between the ice-breaking head 21 and the clamping groove 25. The drone body 4 drives the suspension assembly 17 to gradually descend so that the clamping groove 25 and the ice-breaking head 21 clamp the line 3.

[0043] S5 , the power assembly 23 is triggered, and the piston cylinder 22 transmits vibration to the ice-breaking head 21 and the line 3 , thereby removing ice from the line 3 .

[0044] When the present invention is used, the maximum pressure on the spring 14 is:

[0045] Among them, P max is the maximum pressure on spring 14, n d is the number of movable pulleys in the movable pulley set 16, M1 is the weight of the mounting assembly 1, M2 is the weight of the de-icing assembly 2, and g is the acceleration due to gravity.

[0046] It can be inferred that the maximum distance between the ice breaking head 21 and the wire clamping groove 25 is:

[0047]

[0048] Among them, L max is the maximum distance between the ice breaking head 21 and the wire clamping groove 25, P max is the maximum pressure exerted on the spring 14, and k is the elastic coefficient of the spring 14.

[0049] This maximum distance should be greater than the diameter of the required de-icing line 3, so:

[0050]

[0051] Among them, L max is the maximum distance between the ice breaking head 21 and the wire clamping groove 25, n d is the number of movable pulleys in the movable pulley set 16, M1 is the weight of the mounting assembly 1, M2 is the weight of the de-icing assembly 2, g is the acceleration due to gravity, k is the elastic coefficient of the spring 14, and L D is the diameter of the required de-icing line 3.

[0052] At the same time, to ensure that the pressure exerted by the mounting assembly 1 after clamping the line 3 is large enough (the greater the pressure, the less energy is lost when the vibration is transmitted to the line 3), it should be at least twice the weight of the device. When the device is not subjected to external force:

[0053] P min =k×L min >2×(M1+M2)×g

[0054] Among them, P min is the static pressure on the spring 14 when the device is not subjected to external force, k is the elastic coefficient of the spring 14, L min is the compression amount of spring 14 when the device is not subjected to external force (the length of the device slide bar 26 remains unchanged, and this value is only related to the length of spring 14), M1 is the weight of the mounting component 1, M2 is the weight of the de-icing component 2, and g is the acceleration due to gravity.

[0055] In summary, the elastic coefficient of the spring 14 has a range of values:

[0056]

[0057] Where M1 is the weight of the mounting assembly 1, M2 is the weight of the de-icing assembly 2, g is the acceleration due to gravity, and L is the min is the compression amount of spring 14 when the device is not subjected to external force (the length of the device spring rod remains unchanged, and this value is only related to the length of spring 14), n d is the number of movable pulleys in the movable pulley set 16, L D is the diameter of the required de-icing line 3.

[0058] Therefore, for lines 3 of different thicknesses, the adaptability of the present invention can be adjusted by changing the elastic coefficient of the spring 14, and it can be applied to power transmission and distribution lines or ground wires.

[0059] Working principle: When in use, the motor 43 is turned to rotate the conical block 44 and the rectangular block 45, so that the rectangular block 45 is facing downward, and the ring 46 is hung on the conical block 44. The motor 43 is turned to turn the conical block 44 and the rectangular block 45 upward, and the ring 46 is limited on the conical block 44. The hook 18 is hooked into the suspension assembly 17, and then the mounting assembly 1 and the de-icing assembly 2 are erected. After the drone body 4 takes off, the hook 18 is hooked into the ring 11, the suspension assembly 17 is gradually raised, and the telescopic rod 12 is gradually extended. The movable pulley group 16 moves upward with the extension of the telescopic rod 12 and compresses the spring 14. When the drone body 4 leaves the ground, the spring 14 is released. The spring 14 is subjected to the greatest pressure, the ice-breaking head 21 is separated from the wire-clamping groove 25, and the equipment is moved close to the line 3 so that the line 3 is clamped between the ice-breaking head 21 and the wire-clamping groove 25. At this time, the suspension assembly 17 gradually descends, and the spring 14 gradually expands and contracts, pushing the movable pulley assembly 16 to descend, so that the wire-clamping groove 25 and the ice-breaking head 21 clamp the line 3. Then, a signal transmitter is installed on the remote control device or the drone body 4 to transmit a start signal to the signal transmission device 24. The power assembly 23 is triggered, and high-speed gas is generated inside. The vibration is transmitted to the line 3 between the ice-breaking head 21 and the connecting rod 19 through the piston cylinder 22, causing high-frequency vibration of the line 3, thereby removing the ice covering the line 3.

[0060] The above is only a preferred specific implementation method of this embodiment, but the protection scope of this embodiment is not limited to this. Any technician familiar with this technical field can make equivalent replacements or changes based on the technical solution and inventive concept of this embodiment within the technical scope disclosed in this embodiment, and they should be covered by the protection scope of this embodiment.
