Description

Technical Field

[0001] This invention relates to the field of power transmission line de-icing technology, and more specifically, to a de-icing device for overhead power transmission lines. Background Technology

[0002] Line icing refers to the phenomenon where raindrops condense on power transmission lines upon encountering cold air, causing large areas of the lines to be encased in ice. Line icing is a serious natural disaster for power supply systems, capable of causing line towers to collapse or break, and in severe cases, causing a complete power outage. Cold raindrops condense on the power lines, forming ice. If all the power lines within a certain area are covered in ice and snow, this is called line icing. Icing turns thin wires into icicles, and for long-distance high-voltage transmission lines, it increases the load on the towers supporting the high-voltage lines. Severe icing can cause the towers to collapse due to their inability to support the power lines. Icing on the insulator strings on the towers necessitates cutting off power transmission, resulting in widespread power outages. Line icing is a serious disaster, while manual de-icing is the only way to ensure the smooth operation of the power grid.

[0003] In reality, low-altitude power transmission lines are prone to icing due to the low outdoor temperatures, which can affect power supply. Existing de-icing methods include tapping with poles to use vibration to remove the ice, or scraping by attaching ropes to the power lines and moving them to remove the ice. Both methods are inefficient and simplistic, further reducing the efficiency of de-icing and consequently impacting the workers' work.

[0004] Therefore, we propose a de-icing device for overhead power transmission lines to solve the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a de-icing device for overhead power transmission lines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a de-icing device for overhead power transmission lines, comprising a back box, two straps fixedly connected to the back box, and a placement component provided on the back box;

[0007] The back box is connected to two rotatable fixing plates, and one side of each fixing plate is provided with an adjustable placement column;

[0008] The placement column is connected to a height-adjustable cleaning frame, and a drainage funnel is fixedly connected to the cleaning frame. A drain pipe is fixedly connected to the output end of the drainage funnel.

[0009] A heating component is connected to the cleaning frame, a blower is fixedly connected to the cleaning frame, and a drive component is connected to the blower.

[0010] A rotating component is connected to the cleaning frame, and a transmission component is provided on one side of the cleaning frame. The rotating component and the driving component are connected by transmission through the transmission component.

[0011] In this device, workers can pull up multiple telescopic rods to adjust the height of the cleaning frame, positioning it appropriately. The worker then carries the back case on their back using the shoulder straps, facilitating movement and making it easier to remove ice from cables. When the motor operates, the rotating shaft allows outside air to enter the cleaning frame, simultaneously heating the heating wires in the heating chamber, turning cold air into hot air. This hot air is then directed at the cable, melting the ice. The rotating shaft also causes salt particles in the storage cylinder to fall, further accelerating the melting process and improving worker efficiency.

[0012] In a preferred embodiment, the placement component includes a placement slot disposed on the back case, the back case having a charging cavity installed thereon, the back case having a placement cavity, and a soft rubber pad with ventilation holes fixedly connected to the side wall of the back case, with the soft rubber pad located on one side of the shoulder strap.

[0013] In a preferred embodiment, a rotating seat is fixedly connected to the side wall of the back box, a second rotating column is rotatably connected to the rotating seat, and one end of the second rotating column is fixedly connected to two fixed plates. A limiting plate is fixedly connected to the side wall of the back box, a limiting nut is fixedly connected to the limiting plate, and a limiting screw extending into the rotating seat is threaded onto the limiting nut.

[0014] In a preferred embodiment, a rotating rod is provided between the two fixed plates, the side wall of the rotating rod is fixedly connected to the placement column, and a pentagonal limiting block is fixedly connected to one of the fixed plates. A pentagonal insert is provided through the pentagonal limiting block, and one end of the pentagonal insert extends into the rotating rod.

[0015] In a preferred embodiment, the placement column is threaded with multiple telescopic rods, the upper end of the multiple telescopic rods is fixedly connected to a fixing rod, one end of the fixing rod is rotatably connected to a rotating rod, and one end of the rotating rod is fixedly connected to the side wall of the cleaning frame.

[0016] In a preferred embodiment, the heating assembly includes a heating box fixedly connected to the cleaning frame, two wind deflectors fixedly connected to the cleaning frame, a water deflector fixedly connected to the cleaning frame, the water deflector being located below the wind deflectors, and two symmetrical infrared sensors fixedly connected to the cleaning frame.

[0017] In a preferred embodiment, the drive assembly includes a motor fixedly connected to the top of the air box, a rotating shaft fixedly connected to the drive shaft of the motor, and multiple fan blades coaxially fixedly connected to the side wall of the rotating shaft.

[0018] In a preferred embodiment, the rotating assembly includes a crossbar fixedly connected to the side wall of the cleaning frame, one end of the crossbar being rotatably connected to a first rotating column, and the upper end of the first rotating column being fixedly connected to a baffle.

[0019] In a preferred embodiment, the transmission assembly includes a first pulley fixedly connected to the side wall of the rotating shaft, a second pulley coaxially fixedly connected to the side wall of the first rotating column, the first pulley and the second pulley being connected by a belt drive, a bending rod fixedly connected to the cleaning frame, a storage cylinder fixedly connected to one end of the bending rod, and a baffle located below the output end of the storage cylinder.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. The operator can directly remove the parts from the placement cavity and slot in the back box. Then, the operator rotates the rotating rod and simultaneously rotates the limit screw. With the assistance of the limit nut, the second rotating column is limited, and the placement column is further limited. The operator then removes the parts, rotates the multi-section telescopic rod onto the placement column, and simultaneously rotates the rotating rod onto the fixed rod. This fixes the cleaning frame in the appropriate position. After use, the operator can place the parts back into the back box for easy carrying. The modular design of the device further facilitates inspection and maintenance, thereby simplifying the operator's work and indirectly improving work efficiency.

[0022] 2. Workers can pull up the multi-section telescopic rod according to the actual situation to adjust the height of the cleaning frame and position it in a suitable position. Then, workers can carry the back box on their backs using the shoulder straps to further facilitate the movement of the device and make it easier for workers to clean the ice on the cables, thus simplifying their work.

[0023] 3. When the motor is working, the shaft rotates, allowing outside air to enter the cleaning box. Simultaneously, the heating wire in the heating chamber heats up, turning cold air into hot air. This hot air is then blown onto the cable, melting the ice on it. The rotating shaft also causes salt particles in the storage cylinder to fall, further accelerating the melting of the ice. This makes it easier for workers to clean the ice from the cable, simplifying their work and indirectly improving their efficiency. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figures 1-12 A de-icing device for overhead power transmission lines includes a back box 1, with two shoulder straps 2 fixedly connected to the upper part of the back box 1 for easy carrying by the operator. A storage slot 9 within the back box 1 allows for the placement of multi-section telescopic rods 21, further facilitating the carrying of components. The back box 1 also includes a storage cavity 11 with a sealed door and lock for placing cleaning frames 5 and other components. A charging cavity 10 within the back box 1 houses a battery with a charging port and wires. The wires connect to the electrical components on the cleaning frames 5, enabling the battery to supply power. Notably, the cleaning frames 5 have two conductive posts, and conductive clips can be installed on the wires for proper operation of the electrical components. Furthermore, the conductive posts are covered with shielding covers to ensure proper functioning of the conductive posts and the overall device operation.

[0039] Meanwhile, a rotating seat 13 is fixedly connected to the back box 1, and a second rotating column 14 is provided through the rotating seat 13. The rotating seat 13 is provided with an annular groove, and an annular slider is provided in the annular groove. The annular slider is fixedly connected to the second rotating column 14, thereby achieving the purpose of limiting the second rotating column 14. It is particularly noteworthy that a circular plate is connected to one end of the second rotating column 14, and the circular plate is fixedly connected to two fixed plates 3. Therefore, when the second rotating column 14 rotates on the rotating seat 13, the second rotating column 14 rotates normally, thereby enabling the two fixed plates 3 to rotate normally.

[0040] Meanwhile, a limiting plate 15 is fixedly connected to the side wall of the back box 1, and a limiting nut 16 is fixedly connected to the limiting plate 15. A limiting screw 17 is threaded onto the limiting nut 16, and one end of the limiting screw 17 passes through the limiting plate 15 and extends into the rotating seat 13. Therefore, when the operator rotates the limiting screw 17, the limiting screw 17 can limit the second rotating column 14, which makes it easier for the operator to fix the second rotating column 14, thereby limiting the fixing plate 3 accordingly.

[0041] It is also worth noting that a rotating rod 18 is provided between the two fixed plates 3, and a bearing is provided at the connection between the rotating rod 18 and the two fixed plates 3, so that the rotating rod 18 can rotate normally. A pentagonal limiting block 19 is fixedly connected to the side wall of one of the fixed plates 3, and a pentagonal insert rod 20 is inserted into the pentagonal limiting block 19. It is worth noting that one end of the pentagonal insert rod 20 extends into the rotating rod 18, so that the rotating rod 18 can be limited.

[0042] A placement column 4 is fixedly connected to the rotating rod 18. With the assistance of the rotating rod 18, the placement column 4 can rotate normally, thereby allowing the multi-section telescopic rod 21 to rotate as well. When the operator rotates the second rotating column 14 and the rotating placement column 4, it becomes easier for the operator to adjust the multi-section telescopic rod 21, making it easier to store the multi-section telescopic rod 21 and its components. This makes it easier for the operator to carry the device, further facilitating their work and indirectly improving their work efficiency.

[0043] Meanwhile, a fixed rod 22 is fixedly connected to the upper end of the multi-section telescopic rod 21, and a rotating rod 23 is rotatably connected to one end of the fixed rod 22. The fixed rod 22 is provided with a threaded hole, and the rotating rod 23 is provided with a threaded post. This allows the threaded post to extend into the threaded hole, making it convenient for the staff to fix the rotating rod 23 in the fixed rod 22. This further facilitates the disassembly of the cleaning frame 5 and the placement of the cleaning frame 5 into the back box 1, making it convenient for the staff to carry the device and further facilitating their work.

[0044] Meanwhile, the cleaning frame 5 is provided with a through hole, and the upper end of the through hole is fixedly connected to a bellows 8. The bellows 8 is provided with an air inlet, and the air outlet of the bellows 8 is connected to the through hole. The inner top of the bellows 8 is fixedly connected to a motor 28, and the drive shaft of the motor 28 is fixedly connected to a rotating shaft 29. Multiple fan blades 30 are fixedly connected to the side wall of the rotating shaft 29. When the motor 28 works, the fan blades 30 can be rotated, thereby allowing external air to enter the cleaning frame 5.

[0045] Of particular note is that a heating box 24 is fixedly connected to the inner wall of the cleaning frame 5, and the heating box 24 is equipped with a heating wire. It is also noteworthy that the heating box 24 is equipped with an air outlet and an air inlet. Therefore, when the heating wire in the heating box 24 is working, outside air will enter the heating box 24. With the assistance of the heating wire, the cold air can be turned into hot air, which can then be blown towards the cable. It is also noteworthy that a wind baffle 25 is fixedly connected to the side wall of the cleaning frame 5. It is also noteworthy that the wind baffle 25 is arc-shaped, which allows the outside air to enter the cleaning frame 5 and then be concentrated, thereby removing the ice on the cable.

[0046] It is also worth noting that a baffle plate 26 is fixedly connected to the cleaning frame 5, and the baffle plate 26 is located at the bottom of the cleaning frame 5, so water will not flow out of the cleaning frame 5. It is also worth noting that a drain funnel 6 is fixedly connected to the cleaning frame 5, and a drain pipe 7 is fixedly connected to the output end of the drain funnel 6. The drain pipe 7 is equipped with a valve, which further enables the water flowing on the cleaning frame 5 to be discharged.

[0047] It is also worth noting that an infrared sensor 27 is fixedly connected to the side wall of the cleaning frame 5. It is also worth noting that the infrared sensor 27 can detect the position of the cable. Therefore, an alarm is fixedly connected to the back box 1. When the cable deviates from its position, the infrared sensor 27 will activate the alarm, which will facilitate the timely adjustment of the position of the cleaning frame 5 and further facilitate the staff to clean the ice on the cable.

[0048] It is also worth noting that a crossbar 31 is fixedly connected to the cleaning frame 5, and a first rotating column 32 is rotatably connected to one end of the crossbar 31. A second pulley 38 is coaxially fixedly connected to the side wall of the first rotating column 32. It is also worth noting that a baffle 33 is fixedly connected to the upper end of the first rotating column 32, and the baffle 33 is arc-shaped.

[0049] Meanwhile, a bending rod 34 is fixedly connected to the cleaning frame 5, and a storage cylinder 35 is fixedly connected to one end of the bending rod 34. Salt granules are placed in the storage cylinder 35, which is located above the first rotating column 32. It is worth noting that the storage cylinder 35 is provided with a discharge port, which is arc-shaped, and a baffle 33 is located below the discharge port to block the discharge port.

[0050] It is also worth noting that a first pulley 36 is coaxially fixedly connected to the side wall of the rotating shaft 29, and the first pulley 36 and the second pulley 38 are connected by a belt 37. Therefore, when the motor 28 is working, the rotating shaft 29 can rotate accordingly, which in turn causes the first pulley 36 to rotate. With the assistance of the belt 37, the second pulley 38 can rotate accordingly, thereby causing the first rotating column 32 to rotate as well. This allows the salt particles to fall off piece by piece, further cleaning the ice on the cable.

[0051] In this invention, when the operator needs to use this device, the operator can first directly remove the parts from the placement cavity 11 and placement slot 9 in the back box 1. Then, the operator rotates the rotating rod 18, and with the assistance of the rotating seat 13 and the second rotating column 14, the rotating rod 18 can be adjusted to a suitable position. Then, the operator rotates the placement column 4, and with the assistance of the rotating rod 18, the placement column 4 can be adjusted to a suitable position. After that, the operator inserts the pentagonal plug 20 into the pentagonal limiting block 19, so that the rotating rod 18 is limited. At the same time, the operator rotates the limiting screw 17, and with the assistance of the limiting nut 16, the second rotating column 14 is limited. Further, the placement column 4 is limited. Then, the operator removes the parts. Then, the operator rotates the multi-section telescopic rod 21 onto the placement column 4, and at the same time, the operator rotates the rotating rod 23 onto the fixing rod 22, so that the cleaning frame 5 is fixed in a suitable position. After that, the operator connects the wire to the suitable position, so that the electrical parts on the cleaning frame 5 can be used normally.

[0052] Afterwards, the staff can pull up the multi-section telescopic rod 21 according to the actual situation, so that the height of the cleaning frame 5 can be adjusted to place the cleaning frame 5 in a suitable position. Then, the staff can carry the back box 1 on their back using the shoulder strap 2. Then, the staff can place the cable between the cleaning frames 5 according to the actual situation. Then, the staff can start the motor and infrared sensor 27 through the controller according to the actual situation. It is particularly noteworthy that the infrared sensor 27 can remind the user whether the cable is in a suitable position, so that the staff can adjust the position according to the actual situation.

[0053] When the motor 28 is working, the shaft 29 will rotate accordingly. When the shaft 29 rotates, the fan blades 30 will rotate. When the fan blades 30 rotate, outside air will enter the cleaning frame 5. At the same time, the electric heating wire in the heating box 24 will be heated, which will turn the cold air into hot air. The hot air will then be blown onto the cable. The heat from the electric heating wire will also extend to a part of the external space, which will further melt the ice on the cable.

[0054] Simultaneously, when the rotating shaft 29 rotates, the first pulley 36 rotates, and with the assistance of the belt 37, the second pulley 38 rotates accordingly, which in turn causes the first rotating column 32 to rotate. This causes the salt particles in the storage cylinder 35 to fall out, further increasing the melting speed of the ice. This makes it easier for workers to clean the ice from the cable, thus facilitating their work and indirectly improving their work efficiency.

[0055] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
