Description

Technical Field

[0001] This invention relates to the field of cable de-icing technology, and in particular to a cable de-icing device. Background Technology

[0002] High-voltage power transmission cables, used for long-distance transmission, are typically installed at high altitudes above the ground for safety reasons. When temperatures drop, rain and fog can cause ice to form on the cables, increasing their load and affecting their lifespan and transmission safety. Every winter, line maintenance units spend considerable manpower and resources clearing the ice from the cables. Current methods involve manually tapping the ice or using long ropes to repeatedly knock it off the ground, but these techniques are inefficient and dangerous.

[0003] A search revealed CN107370106A, which discloses a cable de-icing device, comprising an ice-removing mechanism, a power mechanism, and a feeding mechanism. The ice-removing mechanism includes an ice-removing wheel and an ice-removing transmission mechanism. The ice-removing wheel is annular with an angle less than 360 degrees, and its annular notch allows cables to pass through. An ice-removing blade is mounted on the ice-removing wheel. The ice-removing transmission mechanism includes a power wheel A. The annular notch of the ice-removing wheel allows cables to pass through, and the cable can be inserted into the ice-removing wheel through the gap between the lower and upper side plates. The cable can be inserted from the outside, and ice on the cable can be removed.

[0004] CN108173228A discloses a cable de-icing assembly. The key technical points are: a cable de-icing assembly includes a cable body with a groove on it, the length direction of the groove being consistent with the length direction of the cable body. A rack is provided inside the groove, and a flexible baffle is provided at the groove opening. It also includes a de-icing component, comprising a sliding block with a through hole through which the cable body passes. A receiving cavity is provided inside the sliding block, and a gear is provided within the cavity. The gear is rotatably connected to the cavity wall, and the gear meshes with the rack. A cam is connected to the gear's rotating shaft. A de-icing rod is provided inside the cavity, with a trigger end and a de-icing end at its two ends. The de-icing rod is hinged to the cavity wall, and the de-icing end extends into the groove. It also includes a spring, one end of which is connected to the cavity wall, and the other end is connected between the trigger end and the hinge point of the de-icing rod. A traction rope is provided on the outer wall of the sliding block. This assembly can effectively remove ice layers adhering to the surface of the cable.

[0005] The CN101309001B de-icing robot consists of a frame, a de-icing shield, a power supply, a clamping mechanism, and a walking mechanism. The de-icing shield includes a vibration drive device and a shield at the front end in the forward direction, with several pointed cones fixed to the front of the shield. The vibration drive device is a vibration eccentric motor mounted on the frame, which drives the de-icing shield to move back and forth. The clamping mechanism consists of at least two pairs of clamping guide wheels and a clamping opening and closing device. The opening and closing device is a hinge structure, with each pair of guide wheels mounted on a hinge on one side, opening and closing around the hinge axis. The walking mechanism consists of a walking motor and cable-driven wheels, and the power supply is a battery.

[0006] The above technical solutions all disclose de-icing devices that travel on cables, but all of them use fixed mechanisms, which are not convenient for reasonable adjustment when the diameter of the cables is different, resulting in poor versatility. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a cable de-icing device that achieves tight contact between the power wheel and the cable and adjusts the distance between the de-icing component and the cable. It is suitable for cables of different diameters and has a wide range of applications.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0009] A cable de-icing device includes a mounting frame, comprising an upper mounting frame and a lower mounting frame for docking with the outside of the cable body. The upper and lower mounting frames are connected to a power wheel via a slider on opposite sides. One end of the mounting frame is equipped with an electrically controlled telescopic cylinder, the output end of which is rotatably connected to the slider via a connecting rod to drive the power wheel to press tightly against the cable body. The other end of the mounting frame is connected to a cone, inside which is a rotating cylinder for docking with the outside of the cable body. The mounting frame is rotatably connected to a connecting rod, which is inserted into the output end of the electrically controlled telescopic cylinder to drive the rotating cylinder to move along the telescopic direction of the cylinder. The connecting rod is rotatably connected to the rotating cylinder, and a de-icing component is mounted on the rotating cylinder. The outer side of the de-icing component is slidably connected to the inner side of the cone. The rotating cylinder moves to adjust the distance between the de-icing component and the cable body. The power wheel is connected to a drive mechanism, and one end of the rotating cylinder is equipped with a toothed ring that meshes with the output end of the drive mechanism.

[0010] As a further implementation, both the upper and lower mounting brackets are arc-shaped, and the cone includes an upper cone and a lower cone.

[0011] As a further implementation, the mounting bracket is provided with several sliding grooves, and the slider slides in cooperation with the sliding grooves.

[0012] As a further implementation, the electrically controlled telescopic cylinder is installed at one end of the upper mounting frame near the lower mounting frame, and a connecting block is provided at the output end of the electrically controlled telescopic cylinder. The connecting block and the slider are rotatably connected to the connecting rod.

[0013] As a further implementation, a lower connecting frame is provided on the lower mounting frame, and the drive mechanism is provided on the lower connecting frame. The drive mechanism cooperates with the power wheel through a worm gear mechanism.

[0014] As a further implementation, the rotating mechanism adopts a drive motor, which is mounted on the lower mounting bracket. A drive gear is provided at the output end of the drive motor, and the drive gear cooperates with the end face gear ring of the rotating cylinder.

[0015] As a further implementation, the connecting rod includes a guide rod and an insert rod. The guide rod is disposed on the outside of the rotating cylinder and is arranged along the axial direction of the rotating cylinder. One end of the guide rod is connected to a guide ring disposed on the circumference of the rotating cylinder. The guide ring is semi-circular and is rotatably connected to the rotating cylinder and located in an annular groove on the circumference of the rotating cylinder. The other end of the guide rod is rotatably connected to the insert rod. The insert rod is inserted into the connecting block at the output end of the electrically controlled telescopic cylinder. The mounting bracket is rotatably connected to the middle position of the insert rod.

[0016] As a further implementation, the de-icing assembly includes multiple brush rods, which are arranged perpendicularly to and pass through the rotating cylinder. One end of each brush rod is connected to a sliding part via a spring, and the sliding part slides in conjunction with the inner side of the cone.

[0017] As a further implementation, the sliding part is connected to the cutting blade.

[0018] As a further implementation, a transition blade is provided at the end of the brush bar furthest from the mounting bracket.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The output end of the electrically controlled telescopic cylinder of the present invention is rotatably connected to the slider via a connecting rod, enabling the power wheel to closely contact the cable body and adapting to cable bodies of different diameters. The rotating cylinder can move via the connecting rod and the electrically controlled telescopic cylinder. The outer side of the de-icing assembly is slidably connected to the inner side of the cone. The movement of the rotating cylinder can further adjust the distance between the de-icing assembly and the cable body, thus achieving overall close contact between the power wheel and the cable, as well as adjustment of the distance between the de-icing assembly and the cable.

[0021] 2. In this invention, one end of the rotating cylinder is provided with an end face gear ring that meshes with the output end of the rotating mechanism. The brush rod is perpendicular to the rotating cylinder and passes through the rotating cylinder. One end of the brush rod is connected to the sliding part by a spring, which enables the rotating cylinder to rotate and drive the brush rod to rotate around the cable body. The transition blade further improves the de-icing effect based on the cutting blade.

[0022] 3. In this invention, the ice layer is first cut and then brushed by a brush rod to further cut the ice on the cable surface, thereby achieving the cleaning of ice on the cable. Attached Figure Description

[0028] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] Example 1

[0030] In a typical embodiment of the present invention, reference is made to Figures 1-2 As shown, a cable de-icing device includes a mounting frame. The mounting frame includes an upper mounting frame 11 and a lower mounting frame 12 for docking with the outside of the cable body. The bodies of the upper mounting frame 11 and the lower mounting frame 12 are semi-circular rings for docking with the periphery of the cable body. This embodiment... Figure 1 Taking the view direction as an example, the cable body 1 is arranged horizontally, the upper mounting bracket 11 is located above the cable body 1, and the lower mounting bracket 12 is located below the cable body 1. The upper mounting bracket 11 and the lower mounting bracket 12 are arranged opposite to each other and are used to connect to the periphery of the cable body 1.

[0031] An electrically controlled telescopic cylinder 24 is installed at the bottom right end of the upper mounting bracket 11 near the lower mounting bracket 12. The telescopic shaft at the output end of the electrically controlled telescopic cylinder 24 is horizontally positioned, located between the upper mounting bracket 11 and the lower mounting bracket 12. Slide grooves are provided on opposite sides of the upper mounting bracket 11 and the lower mounting bracket 12, and sliders slide within these grooves. The sliders are connected to drive wheels 23. In this embodiment, two drive wheels 23 are correspondingly provided on each mounting bracket. The drive wheels 23 can slide up and down within the slide grooves via the sliders.

[0032] The telescopic shaft is a transmission rod 22, and two connecting blocks 18 are correspondingly set on the transmission rod. The connecting block 18 is rotatably connected to one end of the connecting rod 21, and the other end of the connecting rod 21 is rotatably connected to the slider 20. There are a total of four connecting rods, which are rotatably connected to four sliders 20.

[0033] When the electrically controlled telescopic cylinder 24 operates, it drives the transmission rod 22 to extend, enabling the slider 20 to slide within the groove of the mounting bracket via the connecting rod 21. This allows the drive wheels 23 on the upper mounting bracket 11 and lower mounting bracket 12 to move closer together, facilitating close contact between the drive wheels 23 and the cable body. When the transmission rod 22 retracts, the drive wheels 23 move away from each other, making it easier to detach the entire device from the cable body 1.

[0034] A lower connecting frame 14 is provided on the lower mounting frame 12, and a drive mechanism is provided on the lower connecting frame 14. The drive mechanism includes a rotary motor 16, which is connected to a hydraulic coupler 17. Two worm gears 26 are connected to the hydraulic coupler 17, and the worm gears 26 mesh with worm wheels 25. A worm wheel 25 is connected to a power wheel 23 on the lower slider 20. When the rotary motor 16 works, it drives the hydraulic coupler 17, which in turn drives the two worm gears 26 to rotate. The rotation of the worm gears 26 drives the power wheel 23 to rotate, and the rotation of the power wheel 23 drives the device forward.

[0035] like Figure 1 As shown, the upper mounting bracket 11 and the lower mounting bracket 12 are fixedly connected to the left ends of a cone. The cone includes an upper cone 6 and a lower cone 7, both of which are semi-circular rings. When joined together, they form a complete cone for fitting around the cable body 1. A rotating cylinder 13 is provided on the opposite sides of the upper cone 6 and the lower cone 7. The rotating cylinder 13 is also divided into two symmetrical halves, each of which is a semi-circular ring. This is to facilitate the separation of the upper and lower parts of the entire device during installation and its mounting onto the cable body 1.

[0036] The rotating cylinder 13 is slidably connected to the cone. An annular groove is provided on the circumference of the rotating cylinder 13. A guide ring 9 is provided on the annular groove. The guide ring 9 is connected to the annular groove through a bearing to achieve the rotational connection between the guide ring 9 and the rotating cylinder 13. The guide ring 9 is also divided into two halves, each half being a semi-circular ring. The guide ring 9 is connected to the electrically controlled telescopic cylinder 24 and the mounting bracket through a connecting rod.

[0037] The connecting rod includes a guide rod 8 and an insertion rod 19. One end of the guide rod 8 is connected to a guide ring 9, and the other end passes through a cone and is rotatably connected to the end of the insertion rod 19. The guide rod is horizontally positioned, and the insertion rod 19 is vertically positioned. The other end of the insertion rod 19 is inserted into a groove on the connecting block 18 at the far end of the transmission rod 22. A rod is fixed on the upper mounting bracket 11 and is rotatably connected to the middle position of the insertion rod 19. When the transmission rod 22 extends, i.e., when the transmission rod 22 moves to the left, the top of the insertion rod 19 can move to the right, thereby pulling the guide rod 8 to the right. The guide rod 8 pulls the rotating cylinder to the right through the guide ring 9. This process also ensures that the power wheel is in close contact with the cable body.

[0038] It is understandable that the insertion rod 19 in this embodiment can be set only on the upper mounting bracket, and the lower mounting bracket 12 can be set only on the guide rod 8, without the need to set the insertion rod 19. This method requires the two halves of the rotating cylinder 13 to be connected by the cooperation of the locking block and the locking groove.

[0039] like Figure 1 As shown, a de-icing assembly is further provided on the rotating cylinder 13. The outer side of the de-icing assembly is slidably connected to the inner side of the cone. The de-icing assembly includes multiple brush rods 2. In this embodiment, four brush rods 2 are provided. The brush rods 2 are perpendicular to the rotating cylinder 13 and pass through the rotating cylinder 13. The top of the brush rod 2 is connected to a sliding part 5 through a spring 4. The sliding part 5 is slidably engaged with the inner side of the cone. A cutting blade 3 is connected to the left end of the sliding part 5. The cutting blade 3 is inclined and extends to the cable body 1 to facilitate the removal of ice on the cable body 1.

[0040] Of the four brush rods 2, the end furthest from the mounting bracket is equipped with a transition blade 2-1 for further removing ice from the cable body. The spring 4 facilitates adjustment of the contact between the brush rod 2 and the periphery of the cable body 1.

[0041] Furthermore, a rotating mechanism is installed on the lower mounting bracket 12. The rotating mechanism includes a drive motor 15, and a drive gear 15-1 is installed at the output end of the drive motor 15. The drive gear 15-1 cooperates with the end face gear ring 13-1 located on the right end face of the rotating cylinder 13. When the drive motor works, it drives the rotating cylinder to rotate through the drive gear. The rotating cylinder 13 drives the brush rod 2 to remove the ice around the cable body 1. The transition blade 2-1 is used to enhance the de-icing effect. The cutting blade is located at the leftmost end of the entire device and is used to break the ice on the surface of the cable body 1 in the first step.

[0042] like Figure 2 As shown, limiting grooves 27 are provided on the outer sides of the upper cone 6 and the lower cone 7. The two are connected by a connecting plate 29 and a connecting bolt 28. When using this device, the distance between the upper and lower cones can be adjusted by unscrewing the connecting bolt 28.

[0043] Specific working principle:

[0044] In use, first loosen the connecting bolts 28 on the connecting plate, while the electric telescopic cylinder 24 is in the retracted state. Then, pry open the upper mounting bracket 11 and the lower mounting bracket 12 so that the cable body 1 passes through the gap between the upper cone 6 and the lower cone 7, the upper mounting bracket 11 and the lower mounting bracket 12, and the rotating cylinder 13 of the two halves of the structure. Then tighten the connecting bolts 28 to complete the installation. During operation, the electric telescopic cylinder 24 drives the connecting block 18 to move forward, which in turn drives the connecting rod 21, which in turn drives the slider 20 to tighten inward, which in turn drives the power wheel 23 to squeeze the cable body 1.

[0045] Simultaneously, the connecting block 18 drives the insertion rod 19 to move forward, which in turn drives the guide rod 8 to move backward. The backward movement of the guide rod 8 drives the guide ring 9 to move backward, which in turn drives the rotating cylinder 13 to move backward, which in turn drives the sliding part 5 to move backward. The backward movement of the sliding part 5, under the action of the upper cone 6 and the lower cone 7, moves inward, thereby adjusting the distance between the cutting blade 3 and the transition blade 2-1 and the cable body 1, thus realizing the adaptation of cable bodies 1 of different widths.

[0046] During operation, the rotating motor 16 drives the hydraulic coupling 17, which in turn drives the two worm gears 26 to rotate. The rotation of the worm gears 26 drives the power wheel 23 to rotate, which in turn drives the device forward. At the same time, the drive motor 15 drives the drive gear 15-1 to rotate. The movement of the drive gear 15-1 drives the end face gear ring 13-1 to rotate the rotating cylinder. The rotating cylinder 13 drives the cutting blade to perform preliminary cutting of the ice. Under the combined action of the overall pushing action and the rotational cutting action, the ice is broken. The remaining ice after the preliminary cutting is cut and scraped by the transition blade. After the ice layer is cut, it is brushed by the subsequent brush rod 2, which further cuts the ice on the surface of the cable, thereby achieving the cleaning of the ice on the cable.

[0047] This device first cuts the ice layer, then uses a brush rod to brush it, further cutting the ice on the cable surface, thus cleaning the ice off the cable.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
