Description

Technical Field

[0001] This invention relates to the field of power technology, and in particular to a de-icing device for overhead power transmission cables. Background Technology

[0002] Power transmission lines are vital lifeline projects. In winter, snow and ice accumulation on transmission lines due to weather conditions increases the load on them. If the weight of the ice exceeds the load-bearing capacity of the transmission line or tower, it can lead to accidents such as line breaks and collapses, damaging the power transmission system.

[0003] Currently, Chinese invention patent CN116845805A discloses a cable de-icing device, including a main body, a de-icing component, and a drive component. The main body has a channel for the cable to pass through. The de-icing component is connected to the main body and is used to remove ice or snow covering the outer periphery of the cable. The drive component is connected to the main body and is used to drive the main body to move along the extension direction of the cable. The de-icing component can remove ice or snow from the surface of the cable, thereby preventing excessive accumulation of ice and snow on the cable surface, which increases the load on the cable and avoids cable damage. However, the de-icing component is not adjustable and can only de-ic cable of a fixed size, resulting in poor adaptability. Summary of the Invention

The multiple fixing members together form a de-icing opening for the power transmission cable to pass through. An ice-pushing member is provided on the side of the fixing member facing the de-icing opening.

[0010] Electricity drives the sliding member to reciprocate linearly along the slide rail, causing the multiple fixed members to move away from or closer to each other, expanding or contracting the de-icing port.

[0011] In some embodiments, the driving component includes:

[0012] The mounting bracket is connected to the end of the mounting base that is away from the slide rail;

[0013] A movable wheel is rotatably mounted on the end of the mounting bracket away from the mounting base;

[0014] A drive motor is installed inside the accommodating cavity and connected to the movable wheel;

[0015] The first rotating wheel assembly includes a first rotating shaft and two first turntables. The first rotating shaft is rotatably mounted on one end of the mounting bracket near the mounting base. The two first turntables are arranged on the first rotating shaft at intervals. Friction grooves are formed on the inner surface of the first turntables. Multiple friction strips are arranged circumferentially on the first rotating shaft between the two first turntables.

[0016] In some embodiments, the friction groove extends radially along the first turntable, and the friction strip extends axially along the first rotation axis.

[0018] In some embodiments, the second turntable has a mounting groove, the end of the connecting shaft is movably fitted into the mounting groove, and the inner wall of the mounting groove is provided with a plurality of buffer components, which abut against the connecting shaft.

[0019] In some embodiments, the buffer component includes:

[0020] A telescopic spring post is installed on the inner wall of the mounting groove;

[0021] The buffer block is connected at one end to the telescopic spring column and at the other end to the connecting shaft; the buffer block has a telescopic shaft inside.

[0022] In some embodiments, the de-icing device further includes:

[0023] A fixing base is located at the bottom of the main body;

[0024] A shovel plate is installed on the fixed base, and the shovel plate is inclined towards the direction of the main body. The end of the shovel plate away from the fixed base is provided with an ice-shoveling part, and the ice-shoveling part protrudes from the main body along the forward direction of the main body.

[0025] In some embodiments, the fixed base has a sliding groove, and an mounting plate is movably assembled in the sliding groove, with the shovel plate fixed on the mounting plate; one end of the sliding groove is provided with a limiting plate, which is detachably connected to the fixed base and covers the end of the sliding groove.

An ice-pushing member for de-icing is provided on the side of the fixed members facing the de-icing opening. Electric power drives the sliding member to reciprocate linearly along the slide rail, and the fixed members slide synchronously with the sliding member. This causes the multiple fixed members to either move away from each other to expand the de-icing opening or move closer to each other to contract the de-icing opening, thereby adjusting the diameter of the de-icing opening to suit power transmission cables of different specifications and sizes, improving the overall adaptability of the de-icing device.

[0045] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0048] See Figures 1-8 As shown, this embodiment of the invention provides a de-icing device for overhead power transmission cables, including a main body 1, a drive assembly 2, and a de-icing assembly 3. The main body 1 has a receiving cavity, and one end of the main body 1 has an installation port 101. The drive assembly 2 is installed in the receiving cavity and is used to drive the main body 1 to move along the power transmission cable. The de-icing assembly 3 includes a mounting base 31, a slide rail 32, a sliding member 33, and a fixing member 34. The mounting base 31 is fixed in the installation port 101. The slide rail 32 is installed on the mounting base 31 and extends radially along the mounting base 31. Multiple slide rails 32 are arranged circumferentially, and each slide rail 32 is equipped with a sliding component 33. The end of the sliding component 33 facing away from the slide rail 32 is connected to a fixing component 34. Multiple fixing components 34 surround to form a de-icing opening 341 for the power transmission cable to pass through. An ice-pushing component 342 is provided on the side of the fixing component 34 facing the de-icing opening 341. Electricity drives the sliding component 33 to move back and forth in a straight line along the slide rail 32, causing the multiple fixing components 34 to move away from or closer to each other, expanding or contracting the de-icing opening 341, thereby adjusting the distance between the ice-pushing component 342 in the de-icing opening 341 and the ice on the power transmission cable, facilitating ice breaking.

[0049] When the sliding member 33 is electrically driven to reciprocate linearly along the slide rail 32, the fixing member 34 slides synchronously with the sliding member 33. This causes multiple fixing members 34 to either move away from each other to expand the de-icing opening 341 or move closer to each other to contract the de-icing opening 341, thereby adjusting the diameter of the de-icing opening 341 to make it suitable for power transmission cables of different specifications and sizes, thus improving the overall adaptability of the de-icing device. When de-icing power transmission cables with smaller diameters, this application can reduce the diameter of the de-icing opening 341 through the cooperation of the sliding member 33 and the slide rail 32, preventing the ice-pushing plate inside the de-icing opening 341 from failing to contact the ice attached to the power transmission cable.

[0050] The main body 1 serves as the mounting carrier for the drive assembly 2 and the de-icing assembly 3, and is detachably connected to the mounting base 11. To facilitate the installation of the main body 1 on the power transmission cable, in some embodiments, the main body 1 has a detachable structure. The main body 1 includes a first seat and a second seat detachably connected to the first seat. The first and second seats can be arranged opposite each other, forming a receiving cavity. Notches are provided at one end of the first seat and one end of the second seat. When the first and second seats are connected, the two notches face each other to form an installation opening 101, facilitating the passage of the power transmission cable. The power transmission cable is installed by clamping it towards the center from both sides of the main body 1, and is then secured with bolts threaded onto both sides of the main body 1. Both the first and second seats are connected to the mounting base 11. It should be noted that the mounting base 31 fixed in the mounting port 101 is also a split structure, with multiple sliding members 33 located on the two split parts of the mounting base 31, so that when the first base body is connected to the second base body, multiple fixing members 34 can surround and form a de-icing port 341, located on the outer periphery of the power transmission cable. In other embodiments, the above-mentioned de-icing device can also be installed at the same time as the power transmission cable is installed.

[0051] See Figure 1 As shown, in some embodiments, the de-icing device further includes a plurality of protective blocks 103, which are spaced apart on the top of the main body 1. There are two protective blocks 103, which extend along the length direction of the main body 1 and are spaced apart along the width direction of the main body 1.

[0052] See Figure 2 As shown, in some embodiments, the de-icing device further includes a signal chamber 105, which is located at the bottom of the main body 1, specifically at the bottom of the mounting base 11. The signal chamber 105 is used to transmit data commands, and the drive component 2 operates according to the data commands from the signal chamber 105.

[0053] See Figure 1 and Figure 2As shown, in some embodiments, the main body 1 is further provided with a protective frame 104 at one end where the mounting port 101 is located. The protective frame 104 is located on the outer periphery of the mounting port 101 to enhance the structural strength of the mounting port 101. When the main body 1 has a left-right split structure, the protective frame 104 is also a split structure.

[0054] See Figure 1 and Figure 4 As shown, in some embodiments, the mounting base 31 is cylindrical, and the mounting opening 101 is circular, with the mounting base 31 and the mounting opening 101 coaxially arranged. A slide rail 32 extends radially along the mounting base 31, and multiple slide rails 32 are distributed circumferentially along the mounting base 31. The sliding member 33 is in the form of a slider and is slidably assembled with the slide rail 32. The slide rail 32 is an electric slide rail 32, thereby driving the sliding member 33 to move along the slide rail 32 by electricity. The structure of the electric slide rail 32 is prior art and will not be described in detail in this invention. To avoid the mounting opening 101 interfering with the relative movement of the slide rail 32 and the sliding member 33, the mounting base 31 may partially extend beyond the mounting opening 101. In other embodiments, the slide rail 32 may also adopt a screw structure, with the sliding member 33 threaded onto the screw. A motor drives the screw to rotate, causing the sliding member 33 to move along the screw, adjusting the relative position of the sliding member 33 on the screw, thereby allowing multiple fixing members 34 to open and close relative to each other.

[0055] See Figure 4 As shown, in some embodiments, the end of the fixing member 34 facing away from the sliding member 33 is inclined towards the central axis of the mounting base 31 to reduce the size of the de-icing opening 341 formed by the fixing members 34, making it easier for the ice-pushing member 342 on the fixing member 34 to push and scrape ice. The de-icing opening 341 formed by multiple fixing members 34 is conical.

[0056] See Figure 3 and Figure 5As shown, in some embodiments, the drive assembly 2 includes a mounting frame 21, a movable wheel 22, a drive motor 23, and a first rotating wheel assembly 24. The mounting frame 21 is connected to the end of the mounting base 31 away from the slide rail 32. The movable wheel 22 is rotatably mounted on the end of the mounting frame 21 away from the mounting base 31. The drive motor 23 is installed in the accommodating cavity and connected to the movable wheel 22. The first rotating wheel assembly 24 includes a first rotating shaft 241 and two first turntables 242. The first rotating shaft 241 is rotatably mounted on the end of the mounting frame 21 near the mounting base 31. The two first turntables 242 are arranged relatively at intervals on the first rotating shaft 241. Friction grooves 2421 are formed on the inner surface of the first turntables 242. Multiple friction strips 2411 are circumferentially arranged on the first rotating shaft 241 between the two first turntables 242. In use, the drive motor 23 drives the movable wheel 22 to rotate, causing the movable wheel 22 to move along the power transmission cable. As the movable wheel 22 moves, it drives the mounting frame 21 to move, which in turn drives the first rotating shaft 241 in the first rotating wheel assembly 24 to rotate, thereby causing the first turntable 242 to rotate. When the first rotating shaft 241 rotates, the friction strips 2411 on the first rotating shaft 241 and the friction grooves 2421 on the first turntable 242 rub against the ice on the power transmission cable, removing residual ice debris from the de-icing component 3. The uneven edges of the friction grooves 2421 increase frictional resistance, and some ice debris enters the interior of the friction grooves 2421, facilitating cleaning and achieving the function of friction cleaning.

[0057] Friction grooves 2421 extend radially along the first turntable 242, and friction plates 2411 extend axially along the first rotating shaft 241. Multiple friction grooves 2421 are arranged circumferentially along the first turntable 242. Multiple friction plates 2411 are spaced apart circumferentially along the first rotating shaft 241. The friction plates 2411 are fixed to the first rotating shaft 241 and protrude from the shaft wall of the first rotating shaft 241.

[0058] See Figures 3-6As shown, in some embodiments, the drive assembly 2 further includes a second rotating wheel group 25, disposed on a mounting frame 21 between the first rotating wheel group 24 and the movable wheel 22. The second rotating wheel group 25 includes a second rotating shaft 251 and two second turntables 252. The second rotating shaft 251 is rotatably mounted on the mounting frame 21, and the two second turntables 252 are disposed relatively apart on the second rotating shaft 251. Multiple connecting shafts 253 are also connected between the two second turntables 252, and the multiple connecting shafts 253 are spaced apart circumferentially along the second rotating shaft 251. Friction particles 2531 are provided on the connecting shafts 253. When the mounting frame 21 moves, the second rotating shaft 251 rotates, driving the second turntables 252 to rotate, causing the friction particles 2531 on the connecting shafts 253 to rub against the ice on the power transmission cable. One side of the second turntable 252 is connected to a drive shaft 2521, through which a rotatable connection with the mounting frame 21 is achieved.

[0059] When the drive motor 23 drives the movable wheel 22 to rotate, the movable wheel 22, the first rotating wheel group 24, and the second rotating wheel group 25 all move along the power transmission cable, and drive the de-icing assembly 3, including the mounting base 31, to move through the mounting bracket 21. The mounting base 31 then drives the main body 1 to move along the power transmission cable. When the de-icing assembly 3 moves along the power transmission cable, the power transmission cable is located inside the de-icing port 341, and the ice-pushing component 342 inside the fixing component 34 pushes the ice off the power transmission cable. The power transmission cable is located in the top area of ​​the first rotating wheel group 24 and the second rotating wheel group 25 and below the connecting shaft 253. The friction grooves 2421 and friction strips 2411 on the first rotating wheel group 24 further rub and remove the ice residue remaining after the de-icing assembly 3 has de-iced, and the friction particles 2531 on the second rotating wheel group 25 further rub and remove the ice residue remaining after the first rotating wheel group 24 has de-iced.

[0060] It should be noted that the connecting shaft 253 is movably connected to the second turntable 252. When installing the de-icing device, the second turntable 252 and the second rotating shaft 251 can be installed first, and then the connecting shaft 253 can be installed, so that the power transmission cable is located between the connecting shaft 253 and the second rotating shaft 251. Multiple connecting shafts 253 can be provided, and the central axes of multiple connecting shafts 253 are located on the same horizontal plane.

[0061] To ensure the main body 1 can be stably mounted on the power transmission cable, in some embodiments, the drive assembly 2 further includes a first clamping wheel and a second clamping wheel, arranged vertically, forming a channel between them for the power transmission cable to pass through. When the de-icing device is in use, the first and second clamping wheels are located on opposite sides of the power transmission cable. The first clamping wheel moves along the power transmission cable, while the second clamping wheel provides resistance to the first clamping wheel through the power transmission cable and moves synchronously with it, ensuring stable movement of the drive assembly 2 on the power transmission cable. The first and second clamping wheels can be mounted on the mounting frame 21. The first clamping wheel can be driven by a motor or move with the mounting frame 21. The grooves of the first and second clamping wheels clamp and limit the power transmission cable, allowing the weight of the cable to act on the second clamping wheel. Combined with the clamping action and suspension method of the two clamping wheels, this prevents the entire de-icing device from shifting during movement, ensuring the entire de-icing device is fitted over the outside of the power transmission cable.

[0062] See Figure 3 and Figure 5 As shown, in some embodiments, the mounting frame 21 includes a push frame 211 and a connecting frame 212 connected to each other. A movable wheel 22 is mounted on the push frame 211, and the connecting frame 212 is connected to the push frame 211. The push frame 211 provides power for the movement of the connecting frame 212, facilitating increased power output of the device. The first rotating wheel set 24 and the second rotating wheel set 25 are both mounted on the connecting frame 212. One end of the connecting frame 212 is provided with an assembly block 2121, which is connected to the mounting base 31 to drive the mounting base 31 to move, thereby driving the main body 1 to move.

[0063] See Figure 7 and Figure 8 As shown, in some embodiments, the second turntable 252 has a mounting groove 2522, and the end of the connecting shaft 253 is movably fitted into the mounting groove 2522. Multiple buffer components 4 are circumferentially arranged on the inner wall of the mounting groove 2522, and the buffer components 4 abut against the connecting shaft 253. The buffer components 4 limit and buffer the connecting shaft 253, reducing the vibration amplitude of the connecting shaft 253 during movement.

[0064] In some embodiments, the buffer assembly 4 includes a telescopic spring column 41 and a buffer block 42. The telescopic spring column 41 is installed on the inner wall of the mounting groove 2522. One end of the buffer block 42 is connected to the telescopic spring column 41, and the other end abuts against the connecting shaft 253. A telescopic shaft 43 is provided inside the buffer block 42. When the connecting shaft 253 contacts the friction particles 2531 for de-icing, the buffer block 42 limits and clamps both ends of the connecting shaft 253. When transmitting vibration force, it works with the telescopic spring column 41 to perform telescopic buffering. At the same time, the telescopic shaft 43 provides damping by utilizing its telescopic properties, reducing the amplitude of vibration that the equipment is subjected to, reducing damage to the equipment itself, thereby improving the service life of the vibration damping mechanism, achieving the function of buffering wear, and facilitating the device's vibration damping and protection functions.

[0065] The buffer block 42 includes a first pressure block portion and a second pressure block portion spaced apart. A telescopic shaft 43 connects the first pressure block portion and the second pressure block portion. The first pressure block portion abuts against the connecting shaft 253, and the second pressure block portion is connected to the telescopic spring column 41. The telescopic shaft 43 improves the buffering performance of the buffer block 42.

[0066] The telescopic spring post 41 includes a guide post and a telescopic spring sleeved on the guide post. The guide post is movably inserted into the inner wall of the mounting groove 2522 and fixed to the buffer block 42. One end of the telescopic spring is connected to the inner wall of the mounting groove 2522, and the other end is connected to the buffer block 42. It should be noted that the inner wall of the mounting groove 2522 has a slot to provide clearance for the telescopic movement of the guide post.

[0067] See Figure 1 and Figure 2 As shown, in some embodiments, the de-icing device further includes a fixed base 5 and a scraper plate 6. The fixed base 5 is located at the bottom of the main body 1, specifically at the bottom of the mounting base 11. The scraper plate 6 is mounted on the fixed base 5 and is inclined towards the main body 1. The end of the scraper plate 6 away from the fixed base 5 is provided with an ice-scraping part 61, which protrudes from the main body 1 along the forward direction of the main body 1. When the main body 1 moves, the ice-scraping part 61 of the scraper plate 6 contacts the longer ice cones on the power transmission cable in advance. The ice cones suspended on the power transmission cable can be removed in advance by the ice-scraping part 61, which facilitates the subsequent de-icing of the de-icing assembly 3. This avoids the de-icing device from being easily damaged by collision when encountering longer ice cones, thus affecting the service life of the device.

[0068] See Figure 1 and Figure 2As shown, in some embodiments, a groove 51 is provided on the fixed base 5, and an mounting plate 52 is movably mounted in the groove 51, with the shovel plate 6 fixed on the mounting plate 52. A limiting plate 53 is provided at one end of the groove 51, and the limiting plate 53 is detachably connected to the fixed base 5 and covers the end of the groove 51. The limiting plate 53 limits and fixes the mounting plate 52 in the groove 51 to ensure reliable installation of the shovel plate 6 and prevent the mounting plate 52 from falling out of the groove 51. The limiting plate 53 and the fixed base 5 are detachably connected. By removing the limiting plate 53 from the fixed base 5, the mounting plate 52 and the shovel plate 6 can be removed from the fixed base 5, facilitating regular maintenance and replacement of the shovel plate 6 and improving its service life. Threaded connecting plates 531 are threaded to both ends of the limiting plate 53, and fixing bolts 532 are threaded to both ends of the threaded connecting plates 531.

[0069] See Figure 1 and Figure 2 As shown, in some embodiments, the bottom of the main body 1 is provided with a mounting surface 102. The mounting surface 102 is located on the side of the main body 1 where the mounting opening 101 is provided and is inclined towards the direction close to the main body 1. The fixing seat 5 is fixed on the mounting surface 102. The inclined mounting surface 102 facilitates the inclined installation of the shovel plate 6 on the fixing seat 5, avoids the main body 1 interfering with the inclination of the shovel plate 6, and ensures that the shovel plate 6 can contact the ice cone in advance.

[0070] The working process of this invention is as follows:

[0071] The de-icing port 341 is fitted onto the outside of the power transmission cable. The drive motor 23 moves the movable wheel 22 along the power transmission cable, and the push frame 211 pushes the connecting frame 212 to slide, facilitating increased power for the device. The sliding rail 32 electrically drives the sliding member 33 to slide, causing the de-icing port 341 formed by the fixed member 34 to expand or contract. This allows for adjustments during de-icing, facilitating convenient ice removal. When the movable wheel 22 is pushed and slid, the first rotating wheel group 24 and the second rotating wheel group 25 contact the power transmission cable inside, and cooperate with the friction strip 2411 and friction groove 2421 to contact the ice, achieving the function of friction cleaning. Then, the friction particles 2531 contact and collide to remove the ice. When the connecting shaft 253 is in contact with the friction particles 2531 for de-icing, the buffer block 42 is used to limit and clamp the two ends of the connecting shaft 253. When transmitting vibration force, the telescopic spring column 41 and the telescopic shaft 43 are used for telescopic buffering to achieve the function of buffering consumption and facilitating the shock absorption and protection of the device. When the de-icing mechanism moves, the length of the protective shovel 6 is longer than that of the de-icing device, so that when the de-icing device encounters an ice cone, the protective shovel 6 pushes it to the bottom of the ice cone in advance, thereby facilitating the de-icing mechanism to treat the ice on the surface of the power transmission cable and increasing the protection function of the device.

[0072] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
