Description

Technical Field

[0001] This invention relates to the field of power facility de-icing technology, specifically to a cable-based reciprocating de-icing device. Background Technology

[0002] Power lines are lines used to transmit electrical energy between power plants, substations, and power users. They are an important part of the power supply system and are responsible for transmitting and distributing electrical energy. In the cold winter, the moisture adhering to the outer surface of the lines will freeze. When the lines freeze, it will affect their normal use. Therefore, appropriate de-icing devices are needed to remove the ice adhering to the surface of the lines.

[0003] However, existing de-icing devices have the following problems:

[0004] Existing de-icing devices, which mostly rely on methods such as tapping to remove ice, can cause significant shaking of the lines, affecting the stability of power transmission. Furthermore, when the line surface is slippery, the de-icing device cannot utilize the friction between the stepping wheel and the line for efficient de-icing, thus hindering effective de-icing. Summary of the Invention

[0005] The purpose of this invention is to provide a cable-based reciprocating de-icing device with excellent de-icing effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable-based reciprocating de-icing device is provided, comprising a base, a suspension assembly, a travel drive assembly, and a scraper assembly.

[0008] The suspension assembly is connected to the base, and the suspension assembly is suspended on the cable, the length of which extends along the X direction;

[0009] The walking drive assembly is mounted on the base and can move along the length of the cable;

[0010] The scraper assembly includes two sets of scrapers spaced apart. The two sets of scrapers are connected by a connector and are located below the cable. They are connected to the walking drive assembly via a transmission structure. While the walking drive assembly moves along the X direction, it can drive the transmission structure to move the two sets of scrapers up and down reciprocally along the Z direction. When the two sets of scrapers move upward to contact the cable, they move in opposite directions to remove the ice layer on the cable. When the two sets of scrapers move downward, they move in opposite directions to separate from the cable. The X direction is perpendicular to the Z direction.

[0011] As a further embodiment of the cable-based reciprocating de-icing device, the walking drive assembly includes a bracket fixed to the base, a motor mounted on the bracket, and two stepping wheels. The two stepping wheels abut against the upper side of the cable and are spaced apart along the X direction. The output shaft of the motor extends along the Y direction and is fixedly connected to the center of one of the stepping wheels. A first pulley is fixed to the end of the output shaft, and a second pulley is fixed to the end of the other stepping wheel. The outer circumference of the stepping wheel is provided with several grooves spaced apart, and the length of the grooves extends along the Y direction. The first pulley is driven to the second pulley via a first belt, and the second pulley is connected to two sets of scrapers via the transmission structure. The Y direction is perpendicular to the X and Z directions.

[0012] As a further embodiment of the cable-based reciprocating de-icing device, the transmission structure includes a support frame, a rotating shaft, a third pulley, a second belt, a guide plate, and a connecting rod. The support frame is fixed to the bottom of the base. The length of the rotating shaft extends along the Y direction. One end of the rotating shaft passes through the support frame and is fixedly connected to the third pulley. The other end of the rotating shaft is fixedly connected to the center of the guide plate. The third pulley is connected to the second pulley via the second belt. The non-center position of the guide plate is connected to the connecting member via the connecting rod.

[0013] As a further embodiment of the cable-based reciprocating de-icing device, the base is a rectangular frame structure, and the two sets of scrapers are located within the rectangular frame of the base; the support frame includes a base plate and two side plates fixed to the upper part of the base plate, the two side plates are spaced apart along the Y direction, and the two side plates are provided with clearance grooves extending through them along the Y direction. The two opposite groove walls of the clearance grooves are respectively provided with sliding grooves extending along the Z direction. The upper ends of the two side plates are respectively connected to two opposite edges of the base along the Y direction; the connecting member includes a movable base and two support rods. The movable seat has sliders on both sides along the X direction, and the sliders are matched with the slide grooves one by one. When the guide plate rotates, it can drive the connecting rod to drive the movable seat to slide along the slide groove. The movable seat is connected to a support rod on both sides along the X direction through a torsion spring. The end of each support rod away from the movable seat is pivotally connected to a set of scrapers. The connecting rod and the guide plate are located on the outside of the support frame. The rotating shaft passes through the two side plates and is fixedly connected to the guide plate. The end of the connecting rod away from the guide plate is hinged to the movable seat.

[0014] As a further embodiment of the cable-based reciprocating de-icing device, a vibration assembly is also included. The vibration assembly includes a first magnetic suction part, a second magnetic suction part, a vibration part, a support frame, and a spring. The first magnetic suction part is fixed to the upper end of the movable seat, the support frame is fixed to the base, the second magnetic suction part is located directly above the first magnetic suction part, and the second magnetic suction part is fixedly connected to the vibration part through a first guide rod passing through the support frame. The first guide rod can move up and down relative to the support frame. The spring is sleeved on the first guide rod, and the two ends of the spring are respectively connected to the support frame and the second magnetic suction part.

[0015] When the movable seat moves upward, the first magnetic part moves toward the direction of the second magnetic part until it magnetically attracts and adheres to the second magnetic part. When the movable seat moves downward, the first magnetic part moves away from the second magnetic part until it separates from the second magnetic part. The spring drives the vibrating part to strike the cable upward to break the ice layer on the cable.

[0016] As a further embodiment of the cable-based reciprocating de-icing device, the vibrating part includes a connecting plate, a first inclined plate, and a second inclined plate. The connecting plate is located above the support frame, and its bottom is fixedly connected to the first guide rod. Both ends of the connecting plate along the Y direction are fixedly connected to the first inclined plate and the second inclined plate, respectively. The first inclined plate and the second inclined plate are located above the connecting plate, and the end of the first inclined plate away from the connecting plate and the end of the second inclined plate away from the connecting plate are connected. The connecting end of the first inclined plate and the second inclined plate has an arc-shaped structure.

[0017] As a further embodiment of the cable-based reciprocating de-icing device, the suspension assembly includes two mounting brackets, two clamping parts, and two sets of push rod assemblies. The two mounting brackets are connected to the base, and the two clamping parts are respectively mounted on one of the mounting brackets, with the two clamping parts located on both sides of the base along the X direction. Each clamping part includes two clamping plates distributed vertically. Each set of push rod assemblies includes at least one first electric push rod, which is mounted on the mounting bracket and connected to one of the clamping plates. The cable is located between the two clamping plates. The first electric push rod can drive the two clamping plates to clamp or release the cable. When the clamping plates release the cable, the walking drive assembly can travel along the length of the cable.

[0018] As a further embodiment of the cable-based reciprocating de-icing device, the suspension assembly further includes two second electric push rods. Two mounting slots are respectively opened on the outer sides of the two frames of the base along the Y direction. The two mounting slots are spaced apart along the X direction. The length of the mounting slot extends along the X direction. A second electric push rod is installed on one side wall of the mounting slot along the X direction. The end of the mounting bracket away from the clamping part has a connecting block facing the mounting slot. The connecting block is located in the mounting slot and connected to the second electric push rod.

[0019] When the first electric push rod drives the two clamping plates to release the cable, one of the second electric push rods can drive the connecting block to move in the X direction within the mounting groove, and simultaneously drive the mounting bracket and the clamping part to move in the X direction. When the clamping plates clamp the cable, the second electric push rod drives the base and the scraper assembly to move in the X direction.

[0020] As a further embodiment of the cable-based reciprocating de-icing device, the mounting frame includes a first mounting portion extending along the X direction, a second mounting portion extending along the Z direction, and two third mounting portions extending along the Y direction. The first and second mounting portions are connected and form an L-shaped structure. The two third mounting portions are spaced apart along the Z direction and connected to the second mounting portions respectively. A first electric push rod is mounted on one side of each of the two third mounting portions. Each first electric push rod is connected to a clamping plate. The clamping plate has an arc-shaped groove recessed towards the third mounting portion, and the cable is located between the two arc-shaped grooves.

[0021] As a further embodiment of the cable-based reciprocating de-icing device, the mounting bracket further includes a second guide rod. The third mounting part is located on both sides of the first electric push rod, and a second guide rod is respectively mounted thereon. The second guide rod can move up and down relative to the third mounting part, and the upper end of the second guide rod is fixedly connected to the clamping plate.

[0022] Beneficial effects:

[0023] This invention uses a suspension assembly to suspend the entire reciprocating de-icing device on the cable, preventing it from detaching and falling. When the travel drive assembly moves along the length of the cable, it drives the entire reciprocating de-icing device to move along the same length. Simultaneously, the travel drive assembly drives the two sets of scrapers in the scraper assembly to move up and down reciprocally, and to open and close repeatedly. When the scrapers move upwards, they come into contact with the ice layer on the outside of the cable, at which point the two sets of scrapers open and can scrape away the ice layer.

[0024] This invention combines scraper de-icing with vibration de-icing, which can effectively remove ice from cables.

[0025] When the ice surface is slippery and movement is impossible via the stepping wheels, the present invention can drive the reciprocating de-icing device to travel along the cable by activating a second electric push rod installed in the direction of travel. Attached Figure Description

[0044] 100. Cables. Detailed Implementation

[0045] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail 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.

[0046] like Figures 1-4 As shown, the cable-based reciprocating de-icing device of this embodiment includes a base 1, a suspension assembly 2, a walking drive assembly 3, and a scraper assembly 4.

[0047] The suspension component 2 is connected to the base 1 and is suspended on the cable 100. The length of the cable 100 extends along the X direction.

[0048] The walking drive component 3 is mounted on the base 1 and can move along the length of the cable 100;

[0049] The scraper assembly 4 includes two sets of scrapers 41 spaced apart. The two sets of scrapers 41 are connected by a connector. The two sets of scrapers are located below the cable 100, and the connector is connected to the walking drive assembly 3 through the transmission structure 5. While the walking drive assembly 3 moves along the X direction, it can drive the transmission structure 5 to move the two sets of scrapers 41 up and down along the Z direction. When the two sets of scrapers 41 move upward to contact the cable 100, the two sets of scrapers 41 move in opposite directions to scrape off the ice layer on the cable 100. When the two sets of scrapers 41 move downward, they move in opposite directions to separate from the cable 100. The X direction is perpendicular to the Z direction.

[0050] The cable 100 passes through the suspension assembly 2, thus suspending the entire reciprocating de-icing device on the cable 100 to prevent it from separating from the cable 100 and falling. When the travel drive assembly 3 travels along the length of the cable 100, it drives the entire reciprocating de-icing device to travel along the length of the cable 100. Simultaneously, the travel drive assembly 3 drives the two sets of scrapers 41 of the scraper assembly 4 to move up and down reciprocally, and also drives the two sets of scrapers 41 to open and close repeatedly. When the scrapers 41 move upwards, they can come into contact with the ice layer on the outside of the cable 100. At this time, the two sets of scrapers 41 open and can scrape away the ice layer on the outside of the cable 100.

[0051] Furthermore, such as Figure 5 As shown, the walking drive assembly 3 includes a bracket 31 fixed on the base 1, a motor 32 mounted on the bracket 31, and two stepping wheels 33. The two stepping wheels 33 abut against the upper side of the cable 100 and are spaced apart along the X direction. The output shaft of the motor 32 extends along the Y direction, and the output shaft of the motor 32 is fixedly connected to the center position of one of the stepping wheels 33. A first pulley 34 is fixed to the end of the output shaft, and a second pulley 35 is fixed to the end of the other stepping wheel 33. Several grooves 331 are spaced apart on the outer periphery of the stepping wheel 33. The length of the grooves 331 extends along the Y direction. The first pulley 34 is connected to the second pulley 35 through a first belt 36. The second pulley 35 is connected to two sets of scrapers 41 through a transmission structure 5. The Y direction is perpendicular to the X and Z directions.

[0052] In this embodiment, the bracket 31 has two sets. Each set of brackets 31 includes two parallel first mounting plates and second mounting plates, and a third mounting plate connected to the upper ends of the first and second mounting plates. The first and second mounting plates are spaced apart along the Y direction. One stepper wheel 33 is mounted between the first and second mounting plates of one set of brackets 31. The bottom of the first mounting plate is fixedly connected to the base 1. The motor 32 is mounted on the outside of one of the second mounting plates, and the output shaft of the motor 32 passes through the second mounting plate and is fixedly connected to the stepper wheel 33, extending to the outside of the first mounting plate and fixedly connected to the first pulley 34. The other stepper wheel 33 is rotatably mounted between the first and second mounting plates of the other set of brackets 31 and is rotatably connected to the second pulley 35 on the outside of the first mounting plate.

[0053] After the reciprocating de-icing device is suspended from the cable 100 by the suspension assembly 2, when de-icing is required, the motor 32 drives the stepper wheel 33 connected to its output shaft to rotate. At the same time, the first pulley 34, which is fixedly connected to the output shaft, rotates synchronously and drives the second pulley 35 to rotate through the first belt 36. When the stepper wheel 33 rotates, the frictional resistance between its outer groove 331 and the ice layer on the cable 100 can drive the entire reciprocating de-icing device to move along the cable 100. When the second pulley 35 rotates, it can drive the two sets of scrapers 41 to move up and down and open and close reciprocally in sync through the transmission structure 5 to achieve the de-icing operation.

[0054] like Figure 6 As shown, the transmission structure 5 includes a support frame 51, a rotating shaft 52, a third pulley 53, a second belt 54, a guide plate 55, and a connecting rod 56. The support frame 51 is fixed to the bottom of the base 1. The length of the rotating shaft 52 extends along the Y direction. One end of the rotating shaft 52 passes through the support frame 51 and is fixedly connected to the third pulley 53. The other end of the rotating shaft 52 is fixedly connected to the center of the guide plate 55. The third pulley 53 is connected to the second pulley 35 through the second belt 54. The non-center position of the guide plate 55 is connected to the connecting member through the connecting rod 56.

[0055] When the second pulley 35 rotates, it drives the third pulley 53 to rotate the shaft 52 through the second belt 54. Since the shaft 52 is fixedly connected to the center of the guide plate 55, it can drive the guide plate 55 to rotate. The connecting rod 56 is hinged to the guide plate 55 through the hinge shaft. The hinge point is located at the non-center position of the guide plate 55. In this embodiment, the eccentric structure design can drive the connecting member through the connecting rod 56 to drive the two sets of scrapers 41 to move up and down, open and close reciprocally in sync.

[0056] Furthermore, the base 1 has a rectangular frame structure, and the two sets of scrapers 41 are located within the rectangular frame of the base 1; the support frame 51 includes a base plate 511 and two side plates 512 fixed to the upper end of the base plate 511. The two side plates 512 are spaced apart along the Y direction, and the two side plates 512 are provided with clearance grooves 513 extending through them along the Y direction. The two opposite groove walls of the clearance grooves 513 are respectively provided with sliding grooves 514 extending along the Z direction. The upper ends of the two side plates 512 are respectively connected to the two opposite frames of the base 1 along the Y direction; Figure 7 As shown, the connector includes a movable seat 42 and two support rods 43. The movable seat 42 has sliders 44 on both sides along the X direction. The sliders 44 are matched with the slide grooves 514 one by one. When the guide plate 55 rotates, it can drive the connecting rod 56 to drive the movable seat 42 to slide along the slide grooves 514. The movable seat 42 is connected to a support rod 43 on both sides along the X direction through a torsion spring. The end of each support rod 43 away from the movable seat 42 is pivotally connected to a set of scrapers 41. The connecting rod 56 and the guide plate 55 are located on the outside of the support frame 51. The rotating shaft 52 passes through the two side plates 512 and is fixedly connected to the guide plate 55. The end of the connecting rod 56 away from the guide plate 55 is hinged to the movable seat 42.

[0057] The first pulley 34, the second pulley 35, and the third pulley 53 are located on the same side of the base 1 and the support frame 51 along the Y direction, while the guide plate 55 is located on the other side of the support frame 51 along the Y direction. The rotating shaft 52 passes through the two side plates 512 and is fixedly connected to the third pulley 53 and the guide plate 55 respectively. When the guide plate 55 rotates, it drives the movable seat 42 to slide up and down along the slide groove 514 via the connecting rod 56. When the connecting rod 56 drives the movable seat 42 to slide up along the slide groove 514, the two sets of scrapers 41 move upward under the action of the torsion spring and can open to remove ice when they come into contact with the cable 100. When the connecting rod 56 drives the movable seat 42 to slide down along the slide groove 514, the two sets of scrapers 41 automatically close under the action of the torsion spring, thereby realizing up and down, opening and closing reciprocating ice removal.

[0058] Specifically, each set of scrapers 41 includes a mounting base 411 and two arc-shaped scraper blades 412 fixed on the mounting base 411. The two arc-shaped scraper blades 412 are spaced apart along the X direction. Two ear plates 413 are spaced apart at the bottom of the mounting base 411. A pivot shaft is fixedly connected to one end of the support rod 43 away from the movable seat 42. The pivot shaft is rotatably connected to the two ear plates 413.

[0059] In this embodiment, the movable seat 42 is similar to an I-shaped structure, with a slot on each side along the X direction, and the support rod 43 is connected to the two slot walls by a torsion spring.

[0060] The cable-based reciprocating de-icing device in this embodiment also includes a vibration component 6, such as... Figure 8As shown, the vibration assembly 6 includes a first magnetic suction part 61, a second magnetic suction part 62, a vibration part 63, a support frame 64, and a spring 65. The first magnetic suction part 61 is fixed to the upper end of the movable seat 42, the support frame 64 is fixed to the base 1, the second magnetic suction part 62 is located directly above the first magnetic suction part 61, and the second magnetic suction part 62 is fixedly connected to the vibration part 63 through a first guide rod 66 passing through the support frame 64. The first guide rod 66 can move up and down relative to the support frame 64. The spring 65 is sleeved on the first guide rod 66, and the two ends of the spring 65 are respectively connected to the support frame 64 and the second magnetic suction part 62.

[0061] When the movable seat 42 moves upward, the first magnetic part 61 moves toward the direction of approaching the second magnetic part 62 until it magnetically attracts and adheres to the second magnetic part 62. When the movable seat 42 moves downward, the first magnetic part 61 moves toward the direction of away from the second magnetic part 62 until it separates from the second magnetic part 62. The spring 65 drives the vibrating part 63 to strike the cable 100 upward to break the ice layer on the cable 100.

[0062] Specifically, the first magnetic attraction part 61 is a ring-shaped structure, and the second magnetic attraction part 62 is a circular magnet with a diameter larger than the outer diameter of the electromagnetic ring. The magnetic poles of the first magnetic attraction part 61 and the second magnetic attraction part 62 are opposite. Therefore, when the moving seat 42 moves upward and approaches the first magnetic attraction part 61 and the second magnetic attraction part 62, the first magnetic attraction part 61 and the second magnetic attraction part 62 attract each other and stick together. When the moving seat 42 moves downward, the first magnetic attraction part 61 drives the second magnetic attraction part 62 to move downward. At this time, the spring 65 is pulled and stored. When the pulling force of the moving seat 42 on the first magnetic attraction part 61 is greater than the attraction force between the first magnetic attraction part 61 and the second magnetic attraction part 62, the first magnetic attraction part 61 and the second magnetic attraction part 62 separate. At this time, through the reset action of the spring 65, the vibrating part 63 is driven to impact the cable 100 upward, thereby breaking the ice layer attached to the outside of the cable 100.

[0063] Furthermore, the first magnetic attraction part 61 is an electromagnetic ring, which can control the magnetic attraction and separation of the first magnetic attraction part 61 and the second magnetic attraction part 62 by turning the power on and off.

[0064] This embodiment combines scraper de-icing with vibration de-icing, which can effectively remove the ice layer on the cable 100.

[0065] Specifically, the vibration unit 63 includes a connecting plate 631, a first inclined plate 632, and a second inclined plate 633. The connecting plate 631 is located above the support frame 64. The bottom of the connecting plate 631 is fixedly connected to the first guide rod 66. The two ends of the connecting plate 631 along the Y direction are fixedly connected to the first inclined plate 632 and the second inclined plate 633, respectively. The first inclined plate 632 and the second inclined plate 633 are located above the connecting plate 631. The end of the first inclined plate 632 away from the connecting plate 631 and the end of the second inclined plate 633 away from the connecting plate 631 are connected. The connection end of the first inclined plate 632 and the second inclined plate 633 has an arc-shaped structure.

[0066] In this embodiment, the vibrating part 63 is designed with a triangular structure, which can guide the broken ice fragments to be quickly discharged to the outside of the reciprocating de-icing device. By designing the top of the vibrating part 63 with an arc-shaped structure, the contact area between the vibrating part 63 and the cable 100 can be increased, thereby improving the vibration ice-breaking effect.

[0067] like Figure 9 As shown, the suspension assembly 2 includes two mounting brackets 21, two clamping parts 22, and two sets of push rod assemblies. The two mounting brackets 21 are connected to the base 1. The two clamping parts 22 are respectively mounted on one of the mounting brackets 21, and the two clamping parts 22 are located on both sides of the base 1 along the X direction. The clamping part 22 includes two clamping plates distributed vertically. Each set of push rod assemblies includes at least one first electric push rod 23. The first electric push rod 23 is mounted on the mounting bracket 21 and connected to one of the clamping plates. The cable 100 is located between the two clamping plates. The first electric push rod 23 can drive the two clamping plates to clamp the cable 100 or release the cable 100. When the clamping plates release the cable 100, the walking drive assembly 3 can walk along the length direction of the cable 100.

[0068] In this embodiment, at least one of the two clamping plates of each clamping part 22 is connected to a first electric push rod 23, which can drive the opening and closing of the two clamping plates. When the first electric push rod 23 drives the two clamping plates to open to the maximum extent, the cable 100 can be placed between the two clamping plates. Then, the first electric push rod 23 drives the two clamping plates to close to a certain extent, creating a gap between the lower clamping plate and the cable. At this time, the stepping wheel 33 can be driven by the motor 32 to move along the cable 100.

[0069] Furthermore, the suspension assembly 2 also includes two second electric push rods 24, and two mounting slots 11 are respectively opened on the outer sides of the two frames along the Y direction of the base 1, such as... Figure 10As shown, two mounting slots 11 are spaced apart along the X direction, and the length of the mounting slots 11 extends along the X direction. A second electric push rod 24 is installed on one side wall of the mounting slot 11 along the X direction. The end of the mounting bracket 21 away from the clamping part 22 has a connecting block 211 facing the mounting slot 11. The connecting block 211 is located in the mounting slot 11 and is connected to the second electric push rod 24.

[0070] When the first electric push rod 23 drives the two clamps to release the cable 100, one of the second electric push rods 24 can drive the connecting block 211 to move in the X direction within the mounting groove 11, and at the same time drive the mounting bracket 21 and the clamping part 22 to move in the X direction. When the clamps clamp the cable 100, the second electric push rod 24 drives the base 1 and the scraper assembly 4 to move in the X direction.

[0071] When the ice surface is slippery and cannot be moved by the stepping wheel 33, the reciprocating de-icing device can be driven to move along the cable 100 by activating the second electric push rod 24 installed in the direction of travel.

[0072] Specifically, the second electric push rod 24 is installed on the groove wall of the mounting groove 11 at the end away from the base 1 along the X direction, so as to... Figure 3 Taking the left side as the direction of travel as an example, when the first electric push rod 23 drives the two clamping plates to release the cable 100, the second electric push rod 24 on the left side drives the drive connecting block 211 to move to the left within the mounting slot 11, simultaneously moving the mounting bracket 21 and the clamping part 22 to the left; then the first electric push rod 23 drives the two clamping plates to clamp the cable 100 (ensuring no relative movement between the clamping plates and the cable 100), and the second electric push rod 24 on the left side drives the base 1 and scraper assembly 4, etc., to move forward to the left. Similarly, when the right side is the direction of travel, the first electric push rod 23 and the second electric push rod 24 on the right side cooperate to achieve movement to the right, which will not be described in detail here.

[0073] In this embodiment, grooves are respectively provided on the upper and lower walls of the mounting groove 11. Correspondingly, protrusions that slide in cooperation with the grooves are respectively provided on the upper and lower sides of the connecting block 211. The grooves and protrusions cooperate to limit the movement and prevent the connecting block 211 from separating from the mounting groove 11. The second electric push rod 24 can drive the connecting block 211 to slide along the mounting groove 11.

[0074] In this embodiment, the mounting bracket 21 includes a first mounting portion 212 extending along the X direction, a second mounting portion 213 extending along the Z direction, and two third mounting portions 214 extending along the Y direction. The first mounting portion 212 and the second mounting portion 213 are connected and form an L-shaped structure. The two third mounting portions 214 are spaced apart along the Z direction and are respectively connected to the second mounting portion 213. A first electric push rod 23 is installed on the opposite side of the two third mounting portions 214. Each first electric push rod 23 is connected to a clamping plate. The clamping plate has an arc-shaped groove recessed towards the third mounting portion 214. The cable 100 is located between the two arc-shaped grooves.

[0075] The two first electric push rods 23 can simultaneously drive the corresponding clamps to move toward each other or toward each other, thereby quickly adjusting the distance between the two clamps to increase the speed of the reciprocating de-icing device driven by the suspension assembly 2.

[0076] To improve the clamping stability of the clamping part 22 and prevent the cable 100 from getting stuck due to the clamping plate tilting when the reciprocating de-icing device is driven by the suspension assembly 2, this embodiment designs a guide structure for the vertical movement of each clamping plate. Specifically, the mounting frame 21 also includes a second guide rod 215, and a second guide rod 215 is respectively installed on both sides of the third mounting part 214 located on the first electric push rod 23. The second guide rod 215 can move vertically relative to the third mounting part 214, and the upper end of the second guide rod 215 is fixedly connected to the clamping plate.
