Description

Technical Field

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

[0002] Under extreme weather conditions such as snow and freezing rain, icing of power transmission lines becomes an unavoidable problem. For severely iced transmission lines, the most effective method is usually manual de-icing, but this method is highly dangerous and slow. With the development of technology, two main methods of de-icing are currently used besides manual labor: thermal de-icing technology, which increases the current in the transmission line to heat up the line and melt the ice; and mechanical de-icing technology, which uses external mechanical force. However, the ground wire of the transmission line lacks the conditions for thermal de-icing because it cannot receive current. Therefore, from the perspective of broader applicability, many scholars have begun to study de-icing robots for transmission line ground wires. Different de-icing robots use different de-icing mechanisms to remove ice from the ground wire of the transmission line by applying mechanical force.

[0003] In existing technologies, de-icing equipment can only knock on the ice during operation. However, even after the ice is broken by knocking, some ice will still remain on the power transmission line, resulting in poor ice removal effect. Moreover, manual operation of the equipment is required for de-icing, leading to low de-icing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a de-icing device for power transmission lines, which aims to solve the technical problems of poor de-icing effect and low de-icing efficiency of existing de-icing equipment on power transmission lines.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a power transmission line de-icing device, comprising:

[0006] The housing has an internal cavity and its bottom and two opposite sides are connected to the cavity. The housing moves vertically from top to bottom and allows the power transmission line to pass through the bottom of the housing and through the interior of the housing.

[0007] A clamping mechanism, connected to the inner wall of the housing, is used to push and clamp the power transmission line along the power transmission line path, and the clamping mechanism has a degree of freedom to move along the axial direction of the power transmission line;

[0008] A drive mechanism is connected to the inner wall of the housing. The power output end of the drive mechanism is rotatably connected to the power transmission line. The drive mechanism is adapted to drive the housing to move along the axial direction of the power transmission line.

[0037] Multiple hammers are connected to the other end of multiple third pushers, and the hammers are used to knock down ice on the power transmission line by means of the extension, retraction and rotation of the third pushers.

[0059] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0060] Please refer to the following: Figures 1 to 6 The present invention provides a de-icing device for power transmission lines. The de-icing device includes a housing 1, a clamping mechanism 2, a driving mechanism 3, a striking mechanism 4, and a blowing mechanism 5. The housing 1 has a cavity 11 formed inside, with its bottom and two opposite sides communicating with the cavity 11. The housing 1 moves vertically from top to bottom, allowing the power transmission line 6 to pass through its bottom and through the interior of the housing 1. The clamping mechanism 2 is connected to the inner wall of the housing 1 and is used to push and clamp the power transmission line 6 radially. The clamping mechanism 2 has a degree of freedom to move axially along the power transmission line 6. The driving mechanism 3 is connected to the inner wall of the housing 1, and its power output end is rolledly connected to the power transmission line 6. The driving mechanism 3 is adapted to drive the housing 1 to move axially along the power transmission line 6. The striking mechanism 4 is connected to the inner wall of the housing 1 and is adapted to strike the ice on the power transmission line 6. The blowing mechanism 5 is connected to the inner wall of the housing 1 and is adapted to blow away the struck ice.

[0061] Compared with the prior art, the de-icing device for transmission line 6 provided by the present invention has a housing 1 that can move along the transmission line 6. The clamping mechanism 2, driving mechanism 3, blowing mechanism 5, and striking mechanism 4 are arranged in parallel inside the housing 1, that is, arranged sequentially along the axial direction of the transmission line 6. First, the striking mechanism 4 is used to knock the ice, and then the blowing mechanism 5 is used to blow away the ice fragments or broken pieces, so as to minimize the ice on the transmission line 6. This solves the technical problems of poor ice removal effect and low de-icing efficiency of de-icing equipment on transmission line 6. It has the technical effect of knocking and blowing the ice on the transmission line, with good ice removal effect and high de-icing efficiency.

[0062] Specifically, the housing 1 moves from above the transmission line 6 in a downward direction and can straddle the transmission line 6. After straddling, the clamping mechanism 2 clamps the transmission line 6. After clamping, the drive mechanism 3 can be started. As the housing 1 moves, the knocking mechanism 4 knocks the ice first, and then the blowing mechanism 5 blows the ice to remove as much ice as possible from the transmission line 6.

[0063] In some embodiments, please refer to Figures 1 to 6The housing 1 is connected to a controller 7, which is electrically connected to a wireless communication unit. The controller 7 is electrically connected to and controls the operation of the clamping mechanism 2, the drive mechanism 3, the striking mechanism 4, and the blowing mechanism 5. Inside the housing 1, the clamping mechanism 2, the drive mechanism 3, the blowing mechanism 5, and the striking mechanism 4 are arranged sequentially along the axial direction of the power transmission line 6. The striking mechanism 4 is located near the end of the housing 1 and at the front end in the direction of movement of the housing 1. The controller 7 includes a control panel, a PLC controller, control buttons, and control circuits. The control buttons can control the operation of the clamping mechanism 2, the drive mechanism 3, the striking mechanism 4, and the blowing mechanism 5. In this embodiment, the controller 7 is located on the outer wall of the housing 1, and the front end in the direction of movement of the housing 1 refers to the end located at the front along the direction of movement of the housing 1. The operating sequence of each mechanism can be preset on the PLC controller 7.

[0064] To achieve remote control of the clamping mechanism 2, drive mechanism 3, striking mechanism 4, and blowing mechanism 5, and to realize the same control functions as the controller 7, in some embodiments, please refer to... Figures 1 to 6 The de-icing device for transmission line 6 also includes a remote controller 8 that is wirelessly connected to the controller 7 via a wireless communication unit. The remote controller 8 has control units adapted to control the operation of the clamping mechanism 2, the driving mechanism 3, the striking mechanism 4, and the blowing mechanism 5. The remote controller 8 has a display screen showing the operating status of the clamping mechanism 2, the driving mechanism 3, the striking mechanism 4, and the blowing mechanism 5. The remote controller 8 has multiple control units, enabling individual control of the aforementioned mechanisms (loads). If one mechanism is in operation, the operating status is displayed as "running". The wireless communication unit can be a pre-existing wireless communication module such as 4G or GPRS, enabling wireless communication between two terminals.

[0065] To facilitate the transportation or handling of housing 1, and to suspend housing 1 above power transmission line 6, in some embodiments, please refer to [reference needed]. Figures 1 to 6The de-icing device for the power transmission line 6 also includes a drone 9. The drone 9 flies in the air and connects to the upper part of the housing 1 for hoisting and moving the housing 1. The drone 9 is wirelessly connected to a remote controller 8 and its operation is controlled by the remote controller 8. The drone 9 is connected to a camera 91, which is used to collect information about the appearance of the power transmission line 6. The drone 9 used in this embodiment is existing technology; its bottom end can connect to the upper part of the housing 1, thereby enabling the handling or hoisting of the housing 1. This allows the housing 1 to be moved above the power transmission line 6, allowing it to straddle the power transmission line 6 for installation. In this embodiment, the drone 9's flight altitude and position can be remotely controlled by the remote controller 8, thus enabling the hoisting or transport of the housing 1. Two connecting rods 92 are connected to the lower end of the drone 9, and the lower ends of both connecting rods 92 are detachably connected to the upper part of the housing 1, thereby enabling the hoisting of the housing 1 and its installation on the power transmission line 6. The camera 91 can monitor the appearance of the transmission line 6, which helps to determine whether there is ice on the transmission line 6 or where there is ice, and then use the knocking mechanism 4 to carry out the operation.

[0066] In some embodiments, please refer to Figures 1 to 6 The housing 1 is connected to a monitor 12, which is adapted to capture images or record videos of the transmission line 6. The monitor 12 is wirelessly connected to a remote control 8 and is adapted to send the collected information to the remote control 8. In this embodiment, the monitor 12 can be a product of existing technology, capable of capturing images of the surface of the transmission line 6 and transmitting the information to the remote control 8. The images or videos captured by the monitor 12 can be viewed on the remote control 8, allowing staff to monitor the information of the transmission line 6 in real time and take timely measures such as de-icing. The monitor 12 is located at the upper end of the housing 1 and can rotate 360° in a circumferential direction in the horizontal plane, facilitating monitoring, taking photos, and recording videos at different locations, so that staff can control the appearance information of the transmission line 6.

[0067] Specifically, the monitor 12 can also see the appearance quality information of the transmission line 6. If any damage is found on the transmission line 6, it can be controlled immediately, which will facilitate the repair or replacement of the section of transmission line 6 in the future.

[0068] In some embodiments, please refer to Figures 1 to 6The housing 1 includes an upper plate 13, a left plate 14, a right plate 15, a guide plate 16, a left semi-cylinder 17, a right semi-cylinder 18, and multiple telescopic push rods 19. The upper plate 13 is horizontally positioned with a slide rail 110 at its lower end along its length. The length of the upper plate 13 is perpendicular to the axial direction of the transmission line 6. The upper end of the left plate 14 is slidably connected to the slide rail 110. The upper end of the right plate 15 is slidably connected to the slide rail 110. The left plate 14 and the right plate 15 are spaced apart and form a cavity 11 between them. A space suitable for the transmission line 6 to pass through is formed between the bottom of the left plate 14 and the bottom of the right plate 15. Each of the opposite end faces of the left plate 14 and the right plate 15 has a recessed groove 111. The two ends of the guide plate 16 are respectively inserted into the grooves 111 of the left plate 14 and the right plate 15. The insertion depth of the guide plate 16 is adjusted by sliding the left plate 14 and / or the right plate 15. The left semi-cylindrical cylinder 17 is located in the cavity 11, is semi-cylindrical in shape, and is axially parallel to the axial direction of the transmission line 6. The right semi-cylindrical cylinder 18 is located inside the chamber 11 and is semi-cylindrical in shape, with its axis parallel to the axis of the power transmission line 6. The left semi-cylindrical cylinder 17 and the right semi-cylindrical cylinder 18 can be combined to form a cylindrical structure, and the axis of the cylindrical structure is along the axis of the power transmission line 6. The clamping mechanism 2, the driving mechanism 3, the striking mechanism 4, and the blowing mechanism 5 are all connected to the inner walls of the left semi-cylindrical cylinder 17 and the right semi-cylindrical cylinder 18. Multiple telescopic push rods 19 are respectively connected at one end to the inner wall of the left plate 14 and at the other end to the left semi-cylindrical cylinder 17; and at one end to the inner wall of the right plate 15 and at the other end to the right semi-cylindrical cylinder 18. The multiple telescopic push rods 19 are used to push the left semi-cylindrical cylinder 17 or the right semi-cylindrical cylinder 18 to move in a direction perpendicular to the axis of the power transmission line 6, so that the clamping mechanism 2 and the driving mechanism 3 clamp the power transmission line 6. The distance between the left semi-cylindrical cylinder 17 and the right semi-cylindrical cylinder 18 is adjusted by the multiple telescopic push rods 19. The width of the upper plate 13 is parallel to the axis of the transmission line 6. The left plate 14 and the right plate 15 have the same structure, as do the left semi-cylinder 17 and the right semi-cylinder 18. They are all arranged symmetrically along the vertical plane of the transmission line 6. Along the axis of the transmission line 6, the left, right, and bottom sides of the left plate 14 and the right plate 15 are open, with the bottom facilitating the passage of the transmission line 6. After the transmission line 6 passes through, it is placed inside the left semi-cylinder 17 and the right semi-cylinder 18 and clamped by the clamping mechanism 2. The left and right sides facilitate the passage of the transmission line 6 through the housing 1. By setting multiple telescopic push rods 19, the left semi-cylinder 17 and the right semi-cylinder 18 can be pushed and moved, which makes it easier for the transmission line 6 to pass through the area between the bottom of the left semi-cylinder 17 and the right semi-cylinder 18. When the left semi-cylinder 17 and the right semi-cylinder 18 come into contact with each other, they can form a cylindrical structure. At this time, the transmission line 6 is located inside the cylindrical structure and is also clamped by the clamping mechanism 2.

[0069] The groove 111 and guide plate 16 allow the left and right semi-cylinders 17 and 18 to maintain translation during movement. Four telescopic push rods 19 are arranged vertically between the left semi-cylinder 17 (right semi-cylinder 18) and the left plate 14 (right plate 15). All telescopic push rods 19 are electrically connected to the controller 7 and their operation is controlled by the controller 7, and also by the remote controller 8. The monitor 12 is located at the upper end of the upper plate 13, avoiding connection to the drone 9. The drone 9 is detachably connected to the upper middle part of the upper plate 13.

[0070] Preferably, an elongated through hole 112 is provided on the upper plate 13 from its upper end to its lower end. Multiple telescopic electric cylinders 113 are provided at the upper end of the upper plate 13. A lever 114 is connected to the telescopic push end of each telescopic electric cylinder 113. The lever 114 passes through the elongated through hole 112, with its upper end connected to the push end of the telescopic electric cylinder 113 and its lower end connected to the upper end of the left plate 14 or right plate 15, thereby driving the left plate 14 or right plate 15 to slide on the slide rail 110. The lower end of the elongated through hole 112 extends through the middle of the slide rail 110, or it can extend to the side of the slide rail 110. The lever 114 can be straight or L-shaped, enabling connection between the telescopic electric cylinder 113 and the left plate 14 or right plate 15, and enabling the push-pull mechanism.

[0071] In some embodiments, please refer to Figures 1 to 6The clamping mechanism 2 includes a first left curved rail 21, a first right curved rail 22, multiple first pushers 23, and multiple rollers 24. The first left curved rail 21 is connected to the inner wall of the left semi-cylinder 17, and the arc shape of the first left curved rail 21 is adapted to the arc shape of the left semi-cylinder 17. The first right curved rail 22 is connected to the inner wall of the right semi-cylinder 18, and the arc shape of the first right curved rail 22 is adapted to the arc shape of the right semi-cylinder 18. The multiple first pushers 23 are in groups of two, and one end of each group of first pushers 23 is slidably connected to the first left curved rail 21 or... The first right curved rail 22 and the first pusher 23 have the freedom to slide along the arc direction of the first left curved rail 21 or the first right curved rail 22; the two ends of multiple rollers 24 are respectively rotatably connected to the other end of a set of first pushers 23, and the middle of the rollers 24 is used to roll and contact the transmission line 6. The multiple sets of rollers 24 located on the first left curved rail 21 and the first right curved rail 22 are combined to form a clamp on the transmission line 6. The rollers 24 can roll along the axial direction of the transmission line 6, and the distance between the rollers 24 and the transmission line 6 is adjusted by means of the first pusher 23. The first left curved rail 21 and the first right curved rail 22 have the same structure and are symmetrically arranged with the vertical plane of the transmission line 6 as the axis of symmetry. Multiple first pushers 23 can slide on the first left curved rail 21 and the first right curved rail 22, thereby adjusting the pushing and clamping position on the transmission line 6. In this embodiment, multiple rollers 24 contact the outer wall of the transmission line 6. The cross-section of the rollers 24 is hyperbolic, and two rollers 24 can form a clamping action on the transmission line 6. After contacting the transmission line 6, they increase the friction between them, preventing slippage. By controlling the extension and retraction length of the multiple first pushers 23, the distance between the two rollers 24 can be controlled or adjusted to accommodate transmission lines 6 of different diameters. The first pushers 23 are electrically connected to the controller 7 and their operation is controlled by the controller 7, and also by the remote controller 8.

[0072] In some embodiments, please refer to Figures 1 to 6The drive mechanism 3 includes multiple second pushers 31, multiple drive wheels 32, and a drive motor 33. Two second pushers 31 form a group, with one end of each group fixedly connected to the inner wall of the left semi-cylinder 17 or the right semi-cylinder 18. The two ends of the multiple drive wheels 32 are rotatably connected to the other ends of a group of second pushers 31, with the middle of the drive wheels 32 used for rolling connection to the power transmission line 6. The multiple groups of drive wheels 32 located on the left semi-cylinder 17 and right semi-cylinder 18 form a clamping structure around the power transmission line 6. After rotation, the drive wheels 32 can roll axially along the power transmission line 6, thereby driving the housing 1 to move axially along the power transmission line 6. The distance between the drive wheels 32 and the power transmission line 6 is adjusted by means of the second pushers 31. The drive motor 33 is connected to the pushing end of the second pusher 31, and its power output end is connected to the drive wheel 32. The drive motor 33 is used to drive the drive wheel 32 to rotate. The structure of the second pusher 31 is the same as that of the first pusher 23, and both are controlled by the remote controller 8 and the controller 7. Additionally, the drive motor 33 is electrically connected to the controller 7 and its operation is controlled by the controller 7 and the remote controller 8. The drive motor 33 can drive the drive wheel 32 to rotate, thereby allowing the drive wheel 32 to roll on the power transmission line 6, thus enabling the movement of the housing 1. Preferably, a drive motor 33 is connected above each drive wheel 32. The structure or shape of the drive wheel 32 is the same as that of the roller 24. That is, in addition to being able to roll and move on the power transmission line 6, the drive wheel 32 can also clamp the power transmission line 6, thus preventing the housing 1 from falling off the power transmission line 6.

[0073] In some embodiments, please refer to Figures 1 to 6The striking mechanism 4 includes a second left curved rail 41, a second right curved rail 42, multiple third pushers 43, multiple electric push rods 44, and multiple hammers 45. The second left curved rail 41 is connected to the inner wall of the left semi-cylinder 17, and the arc shape of the second left curved rail 41 is adapted to the arc shape of the left semi-cylinder 17. A left slider 46 is slidably connected to the second left curved rail 41. The second right curved rail 42 is connected to the inner wall of the right semi-cylinder 18, and the arc shape of the second right curved rail 42 is adapted to the arc shape of the right semi-cylinder 18. A right slider 47 is slidably connected to the second right curved rail 42. Each of the multiple third pushers 43 is hinged to either the left slider 46 or the right slider 47 at one end. The third pusher 43 has the freedom to slide along the arc of the second left curved rail 41 or the second right curved rail 42 via the left slider 46 or the right slider 47. Multiple electric push rods 44 are respectively hinged at one end to the left slider 46 or the right slider 47 and at the other end to the third pusher 43. The electric push rods 44 are used to push the third pusher 43 to rotate, and after rotation, the third pusher 43 forms a plane perpendicular to the axial direction of the transmission line 6. Multiple hammers 45 are respectively connected to the other end of the multiple third pushers 43. The hammers 45 are used to knock off the ice on the transmission line 6 by means of the extension, contraction, and rotation of the third pusher 43. The structure of the third pusher 43 is the same as that of the first pusher 23. The second left curved rail 41 has the same structure as the first left curved rail 21, and is spaced apart on the inner wall of the left semi-cylinder 17 along a direction parallel to the axial direction of the transmission line 6. The structure of the second right curved rail 42 is the same as that of the first right curved rail 22, and both are spaced apart on the inner wall of the right semi-cylinder 18 along a direction parallel to the axial direction of the transmission line 6. The electric push rod 44 is an electrically controlled telescopic rod that can extend and retract, and the extension length can be adjusted, thereby adjusting the rotation angle of the third pusher 43, and thus adjusting the hammer head 45's striking height or the magnitude of the force applied to the ice. The striking position on the ice can also be adjusted by the extension and retraction of the third pusher 43 itself.

[0074] In this embodiment, two sets of hammers 45 are provided above and below the transmission line 6. In the vertical plane, two third pushers 43 are provided on the second left curved rail 41 and the second right curved rail 42, arranged vertically. The hammers 45 above the transmission line 6 strike downwards, and the hammers 45 below the transmission line 6 strike upwards. The multiple hammers 45 do not contact each other, thus effectively breaking up the ice. After breaking up the ice, it becomes fragmented, which can then be blown away by the blowing mechanism 5.

[0075] To improve the impact of the hammerhead 45 on ice, in some embodiments, please refer to... Figures 1 to 6The hammerhead 45 has an arc-shaped structure 48 on one side near the transmission line 6. The arc shape of the arc-shaped structure 48 matches the outer arc shape of the transmission line 6. The arc-shaped structure 48 has evenly distributed sawtooth structures 49 along its arc direction. The sawtooth structures 49 include multiple spaced sawtooths. A nozzle 51 is provided between two adjacent sawtooths. The height of the nozzle 51 is less than the height of the sawtooth. The nozzle 51 is used to blow away the ice that has been knocked onto the transmission line 6. The blowing mechanism 5 includes multiple blowing pumps 52, multiple mixing boxes 53, and multiple... A purge pipe 54 and multiple heaters 55; multiple purge pumps 52 are respectively connected to the inner wall of the left semi-cylinder 17 or the right semi-cylinder 18; multiple mixing chambers 53 are connected to the inner wall of the left semi-cylinder 17 or the right semi-cylinder 18, and are respectively connected to the purge ends of the multiple purge pumps 52 through pipes; multiple purge pipes 54 are respectively connected to multiple mixing chambers 53 at one end and connected to multiple nozzles 51 at the other end; multiple heaters 55 are respectively connected to multiple mixing chambers 53, and the heaters 55 are used to heat the gas inside the multiple mixing chambers 53. Both the purge pump 52 and the heater 55 are existing technologies, electrically connected to and controlled by the controller 7, and also controlled by the remote controller 8. Operation via the controller 7 controls the purge and heating of ice or debris. The hammer 45's striking of the ice does not affect the nozzle 51, and the nozzle 51's blowing of ice or debris does not affect the hammer 45's striking of the ice. Activating the heater 55 converts the purge air into hot air, which heats the ice or ice blocks, melting them and allowing them to quickly fall off or be removed from the power line 6. The third pusher 43, during its rotation, does not affect the normal operation of the purge mechanism 5.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
