Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and more specifically, to a cable clearing device. Background Technology

[0002] In the current context of rapid economic development, the expansion and optimization of power systems have become a key driving force for industrial progress and social development. In the vast natural environment, guy wires (steel wire ropes or strands used to support and stabilize power poles) are a crucial component connecting the poles to the ground. Obstacles such as kite strings, floating plastic bags, and plant branches often accumulate on these guy wires. Among these, plant growth has a particularly significant impact on guy wires, becoming a hidden threat to the stable operation of the power system. Plants, especially vines, easily spread and entangle on various supporting structures due to their growth characteristics. Guy wires, due to their long-term exposure to the outdoors, become a breeding ground for plant growth. Plant growth not only adds extra weight to the guy wires but also disrupts their mechanical balance, causing the guy wire angle to deviate from the design value, thus affecting the structural stability of the poles and, in extreme cases, even causing the poles to tilt or collapse, resulting in catastrophic damage to power facilities. Currently, the removal of obstacles on guy wires mainly relies on manual labor, with maintenance through regular inspections and manual removal, resulting in low efficiency. Summary of the Invention

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] See also Figures 1 to 5 As shown, the present invention provides a cable clearing device, which includes: a mounting body 10; a movable clamping mechanism 20, including at least two movable clamping parts 21, each movable clamping part 21 being rotatably mounted on the mounting body 10, and forming a clamping space between the at least two movable clamping parts 21; a clearing structure 30, rotatably mounted on the mounting body 10, the clearing structure 30 being located at the cable outlet end of the mounting body 10, the clearing structure 30 having a cable passage communicating with the clamping space, and the clearing structure 30 being used to clear obstacles on the cable; and a driving structure 40, mounted on the mounting body 10, the driving structure 40 being drivenly connected to each movable clamping part 21, and the driving structure 40 being drivenly connected to the clearing structure 30.

[0025] In this embodiment, a clamping space is formed between at least two movable clamping units 21. A portion of the pull wire is located in the clamping space and clamped by the movable clamping units 21. After passing through the clamping space, the pull wire enters the wiring channel of the obstacle clearing structure 30. The wiring channel is connected to the external environment, meaning the entire pull wire obstacle clearing device is mounted on the pull wire. The driving structure 40 is driven by each movable clamping unit 21, enabling the movable clamping units 21 to rotate, thus allowing the pull wire obstacle clearing device to move forward or backward along the length of the pull wire. Simultaneously, the driving structure 40 is driven by the obstacle clearing structure 30, enabling the obstacle clearing structure 30 to rotate relative to the mounting body 10, thereby clearing obstacles (such as vines) on the pull wire. As can be seen from the above, the pull wire obstacle clearing device of this application can clear obstacles on the pull wire during movement. Compared to the prior art's manual removal method, it has higher cleaning efficiency and can reduce the labor intensity of personnel and lower maintenance costs.

[0026] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the movable clamping mechanism 20 further includes a first transmission structure, a drive structure 40 is driven to cooperate with the first transmission structure, the first transmission structure is driven to be connected to at least two movable clamping parts 21, the obstacle clearing structure 30 includes an obstacle clearing part 32 and a second transmission structure, the obstacle clearing part 32 is rotatably mounted on the mounting body 10, the drive structure 40 is driven to cooperate with the second transmission structure, and the second transmission structure is driven to cooperate with the obstacle clearing part 32.

[0027] In this embodiment, the drive structure 40 is driven by the first transmission structure, which is connected to at least two movable clamping parts 21 to drive the movable clamping parts 21 to rotate relative to the mounting body 10, thereby enabling the pull-wire clearing device to move forward and backward relative to the pull wire along its length. The drive structure 40 is driven by the second transmission structure, and through the transmission between the second transmission structure and the clearing part 32, the clearing structure 30 is driven to rotate relative to the mounting body 10 to clear obstacles on the pull wire. The cooperation between the drive structure 40, the first transmission structure, and the second transmission structure fulfills the requirement for automated operation of the pull-wire clearing device. The movement and clearing actions of the pull-wire clearing device can be precisely controlled by remote control or other automated control methods, eliminating the need for manual operation at heights or in dangerous environments, reducing the risk of maintenance work, and improving the flexibility and intelligence of the operation.

[0028] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the drive structure 40 includes a drive motor 41 and a worm gear 42 drivenly connected to the drive motor 41. The first transmission structure includes at least two worm wheels 22, which mesh with the worm gear 42. The at least two worm wheels 22 are correspondingly arranged with at least two movable clamping parts 21. Each movable clamping part 21 includes a rotating shaft 211 and a clamping wheel 212. The clamping wheel 212 is mounted on the rotating shaft 211. Each worm wheel 22 is connected to its corresponding rotating shaft 211.

[0029] In this embodiment, the drive motor 41 is driven by the worm gear 42 to rotate. The rotation of the worm gear 42 drives the worm wheel 22 to rotate, which in turn drives the rotating shaft 211 to rotate. The rotation of the rotating shaft 211 then drives the clamping wheel 212 mounted on it to rotate, thereby enabling the cable clearing device to move forward or backward relative to the cable along the length of the cable. By having at least two worm wheels 22 corresponding to at least two movable clamping units 21, the rotating shaft 211 and clamping wheel 212 of each movable clamping unit 21 can achieve synchronous rotation and clamping action under the drive of the drive structure 40. This multi-point synchronous clamping ensures the stable gripping of the cable by the cable clearing device during movement, allowing the cable clearing device to remain stable even when encountering obstacles or changes in cable conditions.

[0030] In addition, the combination of drive motor 41, worm gear 42, and worm wheel 22 not only provides a stable power source, but also supports automation and remote control. Operators can precisely control the speed and direction of drive motor 41 through remote control or other automated control methods, thereby realizing remote control of the movement direction and speed of the pull-wire obstacle clearing device, improving the safety and intelligence level of the operation.

[0031] In one embodiment, the pull-wire obstacle clearing device also includes a remote controller, which is communicatively connected to the drive motor 41 to control the speed and direction of the drive motor 41, thereby achieving remote control of the movement direction and speed of the pull-wire obstacle clearing device. The remote controller adopts existing technology, and its specific structure will not be described in detail here.

[0032] In one embodiment, the drive structure 40 is a motor.

[0033] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the drive structure 40 further includes a first gear 43, which is fixedly mounted on the worm gear 42. A gear ring structure 321 is provided on the outer peripheral surface of the obstacle clearing part 32. The first gear 43 meshes with the gear ring structure 321. The second transmission structure includes two second gears 33 and two third gears 34. The first gear 43, the two second gears 33, and the two third gears 34 are arranged circumferentially along the obstacle clearing part 32. The first gear 43 is located between the two second gears 33. The two first gears 43 and the two third gears 34 are arranged in a one-to-one correspondence. The second gears 33 mesh with the first gears 43. Each second gear 33 meshes with its corresponding third gear 34, and both third gears 34 mesh with the gear ring structure 321.

[0034] In this embodiment, when the drive motor 41 starts, the rotational power it generates is first transmitted to the worm 42. The rotation of the worm 42 directly drives at least two worm gears 22 meshing with it. The worm gears 22 are connected to the rotating shaft 211 of the movable clamping body 21, thereby transmitting power to the clamping wheel 212, realizing the stable movement of the cable clearing device and the clamping of the cable. The second transmission structure consists of two second gears 33 and two third gears 34. The two second gears 33, the two third gears 34, and the first gear 43 together form a transmission chain. When the drive motor 41 drives the worm 42 to rotate, the first gear 43, which is fixedly mounted on the worm 42, starts to rotate with the worm 42. The rotation of the first gear 43 drives the second gear 33 meshing with it to rotate, and the rotation of the second gear 33 drives the third gear 34 meshing with it to rotate. Both third gears 34 mesh with the gear ring structure 321 on the outer circumference of the clearing part 32, thus driving the clearing part 32 to rotate and realizing the clearing action. Through the direct drive of the first gear 43 and the gear ring structure 321, and the coordinated action of the second gear 33 and the third gear 34 in the second transmission structure, the obstacle clearing unit 32 can achieve continuous and precise obstacle clearing during the movement process. The setting of the second gear 33 and the third gear 34 not only increases the path of power transmission, but also allows the speed or torque of the obstacle clearing unit 32 to be further adjusted by different gear ratios to adapt to different types of obstacles.

[0035] Furthermore, one second gear 33 meshes with one third gear 34, and both third gears 34 mesh with the gear ring structure 321. This allows power to be transmitted from the first gear 43 to the two second gears 33, and then from the two second gears 33 to the two third gears 34. Finally, the two third gears 34 jointly drive the gear ring structure 321. This multi-stage gear transmission mechanism not only enhances the driving capability of the gear ring structure 321, but also ensures the continuity and stability of the rotation of the gear ring structure 321 through the synchronous action of multiple gears. The first gear 43, the two second gears 33, and the two third gears 34 are arranged circumferentially along the clearing section 32, which ensures the uniform distribution of power on the gear ring structure 321 and avoids local overload or imbalance. This makes the rotation of the gear ring structure 321 more stable throughout the clearing process, avoiding intermittent or discontinuous rotation.

[0036] See also Figures 1 to 4As shown, in one embodiment of the present invention, the drive structure 40 further includes a first gear 43, which is fixedly mounted on the worm gear 42. A gear ring structure 321 is provided on the outer peripheral surface of the obstacle clearing part 32. The first gear 43 meshes with the gear ring structure 321. The second transmission structure includes two fourth gears and a synchronous belt. The first gear 43 is located between the two fourth gears. The synchronous belt is wound around the first gear 43 and the two fourth gears. The first gear 43 and the two fourth gears mesh with the inner peripheral surface of the synchronous belt. The gear ring structure 321 meshes with the outer peripheral surface of the synchronous belt.

[0037] In this embodiment, the synchronous belt is a double-sided toothed synchronous belt, meaning that both its inner and outer circumferential surfaces have teeth. When the drive motor 41 starts, it drives the worm gear 42 to rotate. Since the first gear 43 is fixedly mounted on the worm gear 42, the rotation of the worm gear 42 drives the first gear 43 to rotate, which in turn drives the synchronous belt meshing with it to rotate. The movement of the synchronous belt is continuous, thus ensuring continuous power transmission. The two fourth gears also mesh with the inner circumferential surface of the synchronous belt. Therefore, the synchronous belt indirectly drives the two fourth gears to rotate. Due to the relative positional relationship between the two fourth gears and the first gear 43, they can rotate synchronously under the drive of the synchronous belt, playing a role in power distribution and coordination. The outer circumferential surface of the synchronous belt meshes with the gear ring structure 321 on the outer circumferential surface of the obstacle clearing unit 32. When the synchronous belt moves under the drive of the first gear 43 and the two fourth gears, it drives the gear ring structure 321 to rotate continuously, thereby causing the obstacle clearing unit 32 to perform obstacle clearing actions. The above configuration ensures uninterrupted rotation of the gear ring structure 321, guaranteeing the continuity and efficiency of the obstacle removal operation. By using a synchronous belt between the first gear 43 and the two fourth gears, not only is continuous power transmission achieved, but the rotational speeds of the three gears are also coordinated, maintaining the stability and continuity of the gear ring structure 321's rotation even under varying load conditions.

[0038] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the obstacle clearing part 32 includes a rotating seat 322 and a cutting part 323 fixedly mounted on the rotating seat 322. The rotating seat 322 is rotatably disposed at the wire outlet end of the mounting body 10. The toothed ring structure 321 is disposed on the outer peripheral surface of the rotating seat 322. The cutting part 323 is provided with a plurality of cutting blades 3231 at one end away from the movable clamping body 21. The plurality of cutting blades 3231 are arranged at intervals along the circumference of the cutting part 323.

[0039] In this embodiment, the rotation of the rotating base 322 drives the cutting part 323 to rotate, which in turn drives multiple cutting blades 3231 to rotate, thereby cutting and clearing obstacles (such as vines) on the surface of the pull wire. The multiple cutting blades 3231 are arranged at intervals along the circumference of the cutting part 323, which can improve cutting efficiency and allow the obstacle clearing part 32 to cover a wider area during rotation. At the same time, the spaced cutting blades 3231 can also reduce resistance during continuous cutting and avoid jamming or power loss caused by single-blade cutting, thereby improving the continuity and efficiency of obstacle clearing work.

[0040] See also Figures 1 to 5 As shown, in one embodiment of the present invention, a receiving groove 3233 is provided between two adjacent cutting blades 3231.

[0041] In this embodiment, the arrangement of the receiving groove 3233 serves several purposes. First, it effectively reduces the contact area with obstacles during the cutting process, preventing additional resistance caused by tangled plants between the cutting blades 3231. This allows each cutting blade 3231 to cut more easily when it contacts an obstacle, reducing power loss and improving the obstacle-clearing efficiency of the wire-operated obstacle-clearing device. Second, when the cutting part 323 rotates, the receiving groove 3233 can accommodate the cut plants, preventing the cut plants from getting stuck between adjacent cutting blades 3231, causing jamming or interruption of power transmission. This ensures the continuous and stable rotation of the cutting part 323, thereby guaranteeing the continuity and stability of the obstacle-clearing process. Third, the arrangement of the receiving groove 3233 reduces the weight of the cutting part 323 to some extent, reducing the energy consumption of the wire-operated obstacle-clearing device and improving its adaptability and working efficiency in complex terrain.

[0042] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the cutting part 323 is a conical structure, a first notch 3232 is provided on the cutting part 323, and a second notch is provided on the rotating seat 322. The first notch 3232 and the second notch are provided correspondingly, and the area enclosed by the inner wall surface of the rotating seat 322 and the area enclosed by the inner wall surface of the cutting part 323 together form a wiring channel.

[0043] In this embodiment, the corresponding arrangement of the first notch 3232 and the second notch ensures that the pull wire can pass smoothly through the wiring channel. The tight combination of the cutting part 323 and the rotating seat 322, as well as the design of the first notch 3232 and the second notch, not only optimize the wiring channel but also enhance the stability of the overall structure. During the movement of the pull wire clearing device, it can resist external interference and extend the service life of the pull wire clearing device.

[0044] See also Figures 1 to 5As shown, in one embodiment of the present invention, the mounting body 10 includes a first mounting body 11 and a second mounting body 12 arranged at an angle. The first mounting body 11 and the second mounting body 12 are rotatably connected. At least one movable clamping body 21 is rotatably disposed on the first mounting body 11 and at least one movable clamping body 21 is rotatably disposed on the second mounting body 12.

[0045] In this embodiment, the first mounting component 11 and the second mounting component 12 are rotatably connected and set at an angle. By adjusting the angle between the first mounting component 11 and the second mounting component 12, the device can accommodate pull cables of different diameters, thus improving the adaptability of the pull cable clearing device. By rotating the movable clamping component 21 onto the first mounting component 11 and the second mounting component 12, the pull cable clearing device can better balance its lateral and longitudinal stability during operation, reducing the risk of tipping over or slipping.

[0046] See also Figures 1 to 5 As shown, in one embodiment of the present invention, there are multiple movable clamping parts 21 disposed on the first mounting part 11 and the second mounting part 12. The multiple movable clamping parts 21 disposed on the first mounting part 11 are arranged at intervals along the wire routing direction of the pull wire, and the multiple movable clamping parts 21 disposed on the second mounting part 12 correspond one-to-one with the multiple movable clamping parts 21 disposed on the first mounting part 11.

[0047] In this embodiment, the arrangement of multiple movable clamping parts 21 can significantly enhance the movement stability of the pull wire clearing device on the pull wire and the clamping stability of the pull wire. It can also make the pull wire clearing device evenly distribute its weight and pressure during the clearing process, thereby reducing the local stress on the pull wire and preventing damage to the pull wire.

[0048] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the cable clearing device further includes a connecting block 60 and a mounting plate 70. The connecting block 60 is fixedly connected to the mounting body 10, and the mounting plate 70 is fixedly connected to the connecting block 60.

The first through hole and the second through hole are provided in a one-to-one correspondence. One end of the worm gear 42 passes through the first through hole and the second through hole in sequence and is fixedly connected to the first gear 43. The first gear 43 is located on the side of the mounting plate 70 away from the mounting body 10.

[0049] See also Figures 1 to 5As shown, in one embodiment of the present invention, the pull-wire obstacle clearing device further includes two first connecting shafts 71 and two second connecting shafts 72. The two first connecting shafts 71 and the two second connecting shafts 72 are all connected to the mounting plate 70. The two first connecting shafts 71 are correspondingly arranged with two second gears 33, and the two second connecting shafts 72 are correspondingly arranged with two third gears 34. The second gears 33 are rotatably mounted on their corresponding first connecting shafts 71, and the third gears 34 are rotatably mounted on their corresponding second connecting shafts 72.

[0050] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the obstacle clearing unit 32 further includes a fixed seat 324 and a plurality of connecting members. The fixed seat 324 is fixedly mounted on the mounting plate 70. The fixed seat 324 is provided with a plurality of connecting holes 3241, which are spaced apart along the circumference of the fixed seat 324. The rotating seat 322 is an annular structure with a notch. The rotating seat 322 is sleeved on the fixed seat 324. The inner circumferential surface of the rotating seat 322 is in contact with the outer circumferential surface of the fixed seat 324. The plurality of connecting members are provided one-to-one with the plurality of connecting holes 3241. The connecting members are sequentially inserted into the corresponding connecting holes 3241 to fix the fixed seat 324 on the mounting plate 70. The end face of the fixed seat 324 away from the mounting plate 70 can stop the end face of the rotating seat 322 away from the mounting plate 70 to prevent the rotating seat 322 from falling off the fixed seat 324.

[0051] Specifically, the connectors are made of bolts or screws.

[0052] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the pull-wire obstacle clearing device further includes a locking structure 50.

The first end of the screw 51 is sequentially connected to the first mounting body 11 and the second mounting body 12. The nut 52 is sleeved on the second end of the screw 51. When the included angle between the first mounting body 11 and the second mounting body 12 is adjusted to a preset included angle, the first mounting body 11 can be locked in the current position by rotating the nut 52.
