Technical Field
[0001] This invention relates to the field of power equipment technology, specifically to an intelligent and safe wire disconnection and shearing device and its operating method. Background Technology
[0002] In power systems, conductor cutting is a common operation in line maintenance, emergency repairs, and upgrades, especially since cutting operations at heights pose certain risks. Traditional wire cutting tools are mostly manual wire cutters or simple electric wire cutting devices. These tools typically require operators to lift the device by hand to cut, resulting in high labor intensity and inconvenience. Furthermore, manual equipment has limited cutting capacity for thicker cables, leading to low efficiency, particularly in emergency repair scenarios requiring rapid power restoration, making it difficult to meet practical needs.
[0003] Most existing wire-cutting devices lack a stable mounting design, requiring operators to continuously support the device during operation. Prolonged use can easily lead to fatigue, and the swaying of the equipment at heights can cause operational instability, increasing the risk of accidents. These problems limit the effectiveness of existing wire-cutting tools in complex high-altitude environments. Summary of the Invention
[0004] The purpose of this invention is to provide an intelligent and safe wire cutting device and its operating method, aiming to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] An intelligent safety wire cutting device and its operating method are disclosed, including a support panel, and an insulating rod is detachably connected to the bottom of the support panel. A connecting bolt is provided on the surface of the support panel, and a rotating panel is installed at one end of the connecting bolt. The rotating panel is rotatably mounted on the side of the support panel through the connecting bolt.
[0007] The rotating panel and the supporting panel are respectively provided with dynamic shearing grooves and static shearing grooves on their opposite surfaces;
[0008] The surfaces of the support panel and the rotating panel are jointly provided with a driving component, which is used to drive the rotating panel to rotate.
[0009] Furthermore, the positions of the dynamic shearing groove on the rotating panel and the static shearing groove on the support panel are both close to the connecting bolts.
[0010] Furthermore, the drive assembly includes a drive motor, which is mounted on the surface of the support panel, and a drive gear is mounted on the output end of the drive motor.
[0011] The surface of the support panel is provided with a rolling bearing, and a rotating rod is rotatably connected inside the rolling bearing. A first transmission gear is installed at one end of the rotating rod, and a second transmission gear is provided on the side of the first transmission gear.
[0012] The outer arc surface of the rotating panel is provided with a transmission tooth groove, and the second transmission gear is meshed with the transmission tooth groove.
[0013] Furthermore, a mounting base is provided on the surface of the support panel opposite to the rotating panel, and a current sensor is mounted on the surface of the mounting base. The current sensor is U-shaped.
[0014] Furthermore, the surface of the support panel is provided with a housing, and the rotating panel, the first transmission gear, the second transmission gear and the drive gear are all disposed inside the housing.
[0015] Furthermore, a control box is mounted on the surface of the support panel, and a battery pack is disposed on the surface of the control box.
[0016] A method for operating an intelligent safety wire cutting device, the method comprising the following steps:
[0017] S1: Device Installation
[0018] Secure the support panel to one end of the insulating rod with bolts, and check that the housing on the support panel is properly sealed to ensure that the device is in a stable state.
[0019] S2: Mounting Operation
[0020] The operator holds an insulating rod and lifts the device above the conductor, so that the static shear groove on the support panel hangs on the conductor;
[0021] S3: Current Detection
[0022] The current sensor is activated by enclosing the wire in a U-shaped structure to detect whether the wire is energized. If the current sensor detects current in the wire, the control box prevents the drive components from starting. If no current is detected in the wire, the next step is allowed.
[0023] S4: Driver Startup
[0024] The operator starts the drive assembly through the control box. The drive motor drives the first transmission gear meshing with it to rotate through the drive gear. The first transmission gear then drives the second transmission gear meshing with it to rotate. The second transmission gear finally drives the transmission tooth groove on the outer arc surface of the rotating panel meshing with it to rotate.
[0025] S5: Cutting action
[0026] Under the action of the drive component, the rotating panel rotates around the connecting bolt, and the moving shear groove gradually approaches the stationary shear groove and the wire. When the moving shear groove and the stationary shear groove squeeze the wire, the wire shearing operation is completed.
[0027] S6: Shear Reset
[0028] After shearing is completed, the drive assembly controls the rotating panel to return to its initial position, causing the moving shear groove and the stationary shear groove to move away from each other again.
[0029] The present invention provides an intelligent and safe wire cutting device and its operating method, which have the following beneficial effects:
[0030] The device features a compact structure, lightweight design, and simple operation, making it suitable for single-person high-altitude work. Its arc-shaped static shearing groove design ensures stable mounting on cables, guaranteeing safety and stability during the high-altitude shearing process and significantly reducing the risk of accidents caused by equipment instability. Automated shearing is achieved through a drive assembly; the moving and static shearing grooves precisely match, providing powerful shearing force and featuring an automatic reset function to improve work efficiency. A multi-stage gear reduction system further amplifies the shearing torque, enabling easy cutting of thicker cables and meeting the needs of emergency repairs and complex line maintenance.
[0031] Compared to traditional manual tools, this device reduces labor intensity and improves cutting accuracy and efficiency, making it particularly suitable for emergency repairs requiring rapid power restoration. The device is highly adaptable, applicable not only to power cable cutting but also to communication line and high-altitude steel cable cutting, demonstrating broad practical value. Its lightweight and reliable design gives it significant market value and promotion potential in the field of high-altitude operations. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0040] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0041] like Figures 1-6 As shown in the figure, an intelligent safety wire cutting device and its operating method provided in this embodiment of the invention include a support panel 2, and an insulating rod 1 is detachably connected to the bottom of the support panel 2. The insulating rod 1 is detachably connected to the support panel 2 by means of bolt locking.
[0042] The surface of the support panel 2 is provided with connecting bolts 12, and a rotating panel 8 is installed at one end of the connecting bolts 12. The rotating panel 8 can be rotated on the side of the support panel 2 by the reciprocating rotation of the connecting bolts 12.
[0043] The connecting bolt 12 is securely connected to the support panel 2 via its fixed end, while its rotating end engages with the rotating panel 8. Rolling or sliding bearings are used to reduce friction, allowing the rotating panel 8 to rotate freely around the bolt. The power of the drive assembly 9 is transmitted to the rotating panel 8 via gears, causing it to reciprocate along the axis of the connecting bolt 12. A multi-stage locking design ensures connection stability, and lubrication reduces wear and improves durability, thus achieving a stable and efficient rotation function.
[0044] The rotating panel 8 and the supporting panel 2 have a dynamic shearing groove 11 and a static shearing groove 10 respectively on their opposite surfaces, and both the dynamic shearing groove 11 and the static shearing groove 10 are arc-shaped. The position of the dynamic shearing groove 11 on the rotating panel 8 and the position of the static shearing groove 10 on the supporting panel 2 are close to the connecting bolt 12.
[0045] A drive assembly 9 is provided on the surfaces of the support panel 2 and the rotating panel 8, and the drive assembly 9 is used to drive the rotating panel 8 to rotate.
[0046] In one embodiment of the invention, the initial state of the device is that the moving shearing groove 11 on the rotating panel 8 and the stationary shearing groove 10 on the support panel 2 are far apart from each other. When cutting the cable 3 at a height, the support panel 2 is first fixed to one end of the insulating rod 1 with bolts. The worker holds the insulating rod 1 and lifts the device until it passes over the cable 3, and hangs the stationary shearing groove 10 on the support panel 2 onto the cable 3. Because the stationary shearing groove 10 is arc-shaped, the support panel 2 can be hung on the cable 3 in a stable posture.
[0047] Next, the rotating panel 8 is rotated by the drive assembly 9, and the moving shearing groove 11 gradually approaches the cable 3 and the stationary shearing groove 10. When the moving shearing groove 11 contacts the cable 3, the pressure applied by the drive assembly 9 squeezes the cable 3 between the moving shearing groove 11 and the stationary shearing groove 10, thereby cutting the cable 3. After cutting, the device can be reset to its initial state by the drive assembly 9, making it convenient for the operator to remove the device from the cable 3.
[0048] This invention provides an intelligent cable cutting device that combines safety and efficiency. Through reasonable design and innovative structure, it achieves safe, convenient, and precise operation of high-altitude cable cutting. The device uses an insulating rod as an isolation tool between the operator and the cable, effectively avoiding the risk of electric shock that may result from direct contact with the conductor, thereby significantly improving the safety factor of high-altitude operations. It is particularly suitable for line maintenance and operation in energized environments.
[0049] The device features a compact and lightweight design (weighing only 2.28 kg without batteries), making it easy to operate and suitable for single-person high-altitude work. The use of an arc-shaped static shearing groove design allows the support panel to be stably mounted on the cable, ensuring stability during the shearing process even when working at heights. This design not only improves the safety of shearing operations but also significantly reduces the risk of accidents to operators due to equipment instability.
[0050] During the shearing process, the device utilizes a drive assembly to achieve automated shearing. The moving and stationary shearing grooves on the rotating panel work together to achieve precise cutting by gradually approaching the cable. The drive assembly not only provides powerful shearing force but also enables automatic resetting after shearing. This design reduces manual intervention and improves overall operational efficiency. Simultaneously, the multi-stage gear reduction system amplifies the shearing torque, allowing the device to easily cut thicker cables—a performance particularly important in emergency repairs and maintenance of complex lines.
[0051] Compared to traditional manual wire cutting tools, this device significantly reduces labor intensity while improving cutting accuracy and efficiency. Workers can perform high-altitude cutting operations remotely or from the ground, saving effort and ensuring safety. It demonstrates particularly high efficiency in emergency repair scenarios requiring rapid restoration of power grid power. Whether it's urban power grid maintenance, rural power grid upgrades, or emergency repairs of large transmission lines, this device provides reliable technical support.
[0052] Furthermore, this device boasts strong adaptability and scalability. It is not only suitable for cable cutting in power systems but can also be used for cutting communication lines, high-altitude steel cables, and other applications, demonstrating broad applicability. Its compact design and reliable performance make it a practical and efficient tool in various high-altitude operations, possessing significant market value and promotional potential.
[0053] During this process, all that is needed is for the staff to simply hold the insulating rod 1 with their hands.
[0054] In this embodiment, the drive assembly 9 includes a drive motor 91, which is mounted on the surface of the support panel 2. A drive gear 97 is mounted on the output end of the drive motor 91. A rolling bearing 96 is provided on the surface of the support panel 2, and a rotating rod 98 is rotatably connected inside the rolling bearing 96. A first transmission gear 94 is mounted on one end of the rotating rod 98, and a second transmission gear 95 is provided on the side of the first transmission gear 94. A transmission tooth groove 93 is formed on the outer arc surface of the rotating panel 8, and the second transmission gear 95 meshes with the transmission tooth groove 93. A 92 is also provided between 91 and 2.
[0055] A drive motor 91 is mounted on the surface of the support panel 2, and its output end transmits power to the rotating rod 98 inside the rolling bearing 96 via a drive gear 97. One end of the rotating rod 98 is connected to a first transmission gear 94, which drives a second transmission gear 95 meshing with it to rotate. The second transmission gear 95 meshes with the transmission tooth groove 93 on the outer arc surface of the rotating panel 8, and the torque is amplified step by step through the transmission chain to achieve stable rotation of the rotating panel 8 around the connecting bolt 12.
[0056] The rolling bearings 96 in the transmission process reduce friction and ensure smooth rotation, while the multi-stage gear transmission design optimizes power distribution and improves efficiency. The entire structure is compact, and the precise meshing control of the rotating panel's movement trajectory makes the shearing operation more efficient and accurate, reducing energy consumption and equipment wear, and enhancing the reliability and adaptability of the device. It is particularly suitable for shearing cables of different sizes and strengths.
[0057] In this embodiment, a housing 4 is provided on the surface of the support panel 2, and the rotating panel 8, the first transmission gear 94, the second transmission gear 95, and the drive gear 97 are all disposed inside the housing 4. A control box 6 is mounted on the surface of the support panel 2, and a battery pack 5 is provided on the surface of the control box 6.
[0058] This design effectively protects the transmission structure from external environmental influences such as dust, rain, and other impurities, enhancing the device's durability and operational reliability. The enclosed structure of housing 4 also serves to support and secure the various components, ensuring the precise positioning of the gears and rotating panel during operation, thus improving transmission efficiency and stability.
[0059] The control box 6, mounted on the surface of the support panel 2, houses the control system. A battery pack 5 is externally located within the control box, serving as the power source for the drive components and providing stable power to the drive motor 91 and other electrical parts. The design of the control box 6 allows the operator to centrally control all functions of the device, making operation simple, intuitive, and highly efficient. The rational layout of the housing 4 and control box 6 results in a compact overall structure and even weight distribution, facilitating portability while ensuring operational stability and safety during high-altitude work.
[0060] like Figures 1-5 As shown, in one embodiment of the present invention, a mounting base 13 is provided on the surface of the support panel 2 away from the rotating panel 8, and a current sensor 7 is mounted on the surface of the mounting base 13. The current sensor 7 is U-shaped.
[0061] In this embodiment, when the device is attached to a conductor, the U-shaped current sensor 7 surrounds the conductor within its sensing area and detects the current in the conductor through electromagnetic induction. When the current sensor 7 detects current in the conductor, it transmits a signal to the control module. The control module then prevents the drive component from starting, avoiding cutting the conductor while it is energized, thus ensuring the safety of the operator. If the current sensor 7 detects no current in the conductor, the control module allows the drive component to enter the working state and begin the cutting operation.
[0062] This design enables intelligent judgment during the cutting operation, avoiding the risk of cutting live wires due to misoperation and improving the safety performance of the device. The U-shaped current sensor 7 ensures complete coverage of the conductor, improving the accuracy of current detection. It is also compact and lightweight, without increasing the overall weight and size of the device. By detecting the current, the device can effectively determine the working state of the conductor before cutting, solving the problem of traditional wire cutting devices being unable to determine whether the wire is energized and posing a high risk of electric shock. This design makes the device particularly suitable for the maintenance and emergency repair of high-altitude power lines, improving safety while reducing misoperation and increasing efficiency and reliability.
[0063] In one embodiment of the present invention, a method for operating an intelligent safety wire cutting device is also included, the method specifically comprising the following steps:
[0064] S1: Device Installation
[0065] Secure the support panel 2 to one end of the insulating rod 1 with bolts, and check whether the housing 4 on the support panel 2 is properly sealed to ensure that the device is in a stable state.
[0066] S2: Mounting Operation
[0067] The operator holds the insulating rod 1 and lifts the device above the conductor 3 so that the static shearing groove 10 on the support panel 2 hangs on the conductor 3;
[0068] S3: Current Detection
[0069] The current sensor 7 is activated, and its U-shaped structure surrounds the wire 3 to detect whether the wire 3 is energized. If the current sensor 7 detects that there is current in the wire 3, the control box 6 prevents the drive component 9 from starting. If no current is detected in the wire 3, the next operation is allowed.
[0070] S4: Driver Startup
[0071] The operator starts the drive assembly 9 through the control box 6. The drive motor 91 drives the first transmission gear 94, which is meshed with it, to rotate through the drive gear 97. The first transmission gear 94 then drives the second transmission gear 95, which is meshed with it, to rotate. The second transmission gear 95 finally drives the transmission tooth groove 93 on the outer arc surface of the rotating panel 8, which is meshed with it, to rotate.
[0072] S5: Cutting action
[0073] Under the action of the drive component 9, the rotating panel 8 rotates around the connecting bolt 12, and the moving shearing groove 11 gradually approaches the stationary shearing groove 10 and the wire 3. When the moving shearing groove 11 and the stationary shearing groove 10 squeeze the wire 3, the shearing operation of the wire 3 is completed.
[0074] S6: Shear Reset
[0075] After shearing is completed, the drive assembly 9 controls the rotating panel 8 to return to its initial position, so that the moving shearing groove 11 and the stationary shearing groove 10 move away from each other again.
[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
