[0001] The present invention relates to the technical field of electric power equipment, and in particular to an intelligent safety wire-breaking shearing device and an operating method thereof. Background Art

[0002] In the power system, wire cutting is a common operation in line maintenance, emergency repair and reconstruction, especially in high-altitude environments. Cutting operations are dangerous. Traditional wire cutting tools are mostly manual wire cutters or simple electric wire cutting devices. These tools usually require operators to lift the device directly by hand to cut, which is labor-intensive and inconvenient to operate. In addition, manual equipment has limited cutting capacity for thicker cables, resulting in low efficiency, especially in emergency repair scenarios where power supply needs to be restored quickly, which is difficult to meet actual needs.

[0003] Most existing wire cutting devices lack a stable mounting design. Operators are required to continuously support the device during operation, which can easily lead to fatigue after long-term use. In addition, the shaking of the equipment during high-altitude operations may lead to unstable operation, increasing the risk of accidents. These problems limit the effectiveness of existing shearing tools in complex high-altitude environments. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide an intelligent safety wire-breaking shearing device and an operating method thereof, aiming to solve the technical problems mentioned in the background technology.

[0012] The outer arc surface of the rotating panel is provided with a transmission tooth groove, and the second transmission gear is meshed and connected with the transmission tooth groove.

[0013] Furthermore, a mounting base is provided on the surface of the supporting panel facing away from the rotating panel, and a current sensor is installed on the surface of the mounting base, and the shape of the current sensor is U-shaped.

[0014] Furthermore, a shell is provided on the surface of the supporting panel, and the rotating panel, the first transmission gear, the second transmission gear and the driving gear are all arranged inside the shell.

[0015] Furthermore, a control box is installed on the surface of the support panel, and a battery pack is arranged on the surface of the control box.

[0016] An operating method of an intelligent safety wire breaking shearing device, the method comprising the following steps:

[0020] The operator holds the 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 start current sensor surrounds the wire with its U-shaped structure to detect whether the wire is energized. If the current sensor detects that there is current in the wire, the control box prohibits the drive component from starting. If it detects that there is no current in the wire, it allows to proceed to the next step.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0041] like Figure 1-Figure 6 As shown, an intelligent safety wire cutting device and an operating method thereof provided by an embodiment of the present 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 can be detachably connected to the support panel 2 by a bolt locking connection.

[0042] The surface of the supporting panel 2 is provided with a connecting bolt 12 , and a rotating panel 8 is installed at one end of the connecting bolt 12 . The rotating panel 8 can be set on the side of the supporting panel 2 through the reciprocating rotation of the connecting bolt 12 .

[0043] The connecting bolt 12 is firmly connected to the supporting panel 2 through the fixed end, and its rotating end cooperates with the rotating panel 8, and a rolling bearing or a sliding bearing is used to reduce friction, so that the rotating panel 8 can rotate freely around the bolt. The power of the driving component 9 is transmitted to the rotating panel 8 through the gear, driving it to reciprocate along the axis of the connecting bolt 12. At the same time, the multi-stage locking design ensures the connection stability, and the lubrication treatment reduces wear and improves durability, thereby realizing a stable and efficient rotation function.

[0044] The rotating panel 8 and the supporting panel 2 have opposite surfaces respectively provided with a dynamic shear groove 11 and a static shear groove 10, and both the dynamic shear groove 11 and the static shear groove 10 are arc-shaped. The position of the dynamic shear groove 11 on the rotating panel 8 and the position of the static shear groove 10 on the supporting panel 2 are both close to the connecting bolt 12.

[0045] A driving assembly 9 is commonly provided on the surfaces of the supporting panel 2 and the rotating panel 8 , and the driving assembly 9 is used to drive the rotating panel 8 to rotate.

[0046] In one embodiment of the present invention, the initial state of the device is that the dynamic shear groove 11 on the rotating panel 8 and the static shear groove 10 on the supporting panel 2 are away from each other. When shearing the high-place cable 3, the supporting panel 2 is first fixed to one end of the insulating rod 1 by bolts, and the worker holds the insulating rod 1 to lift the device until it passes over the cable 3, and hangs the static shear groove 10 on the supporting panel 2 on the cable 3. Since the static shear groove 10 is designed in an arc shape, the supporting panel 2 can be hung on the cable 3 in a stable posture.

[0047] Next, the rotation of the rotating panel 8 is started by the driving component 9, and the dynamic shear groove 11 gradually approaches the cable 3 and the static shear groove 10. When the dynamic shear groove 11 contacts the cable 3, the pressure applied by the driving component 9 squeezes the cable 3 between the dynamic shear groove 11 and the static shear groove 10, thereby achieving shearing of the cable 3. After the shearing is completed, the device can be reset to the initial state by the driving component 9, so that the operator can remove the device from the cable 3.

[0048] The present invention provides an intelligent cutting device that is both safe and efficient. Through reasonable design and innovative structure, it realizes safe, convenient and precise operation of high-altitude cable cutting operations. The device uses an insulating rod as an isolation tool between the operator and the cable, effectively avoiding the risk of electric shock caused by direct contact with the wire, thereby greatly improving the safety factor of high-altitude operations, and is particularly suitable for line maintenance and operation in a live environment.

[0049] The device has a compact structure, is lightweight (only 2.28 kg without batteries), and is easy to operate, making it suitable for single-person high-altitude operations. The curved static shear groove design allows the support panel to be stably mounted on the cable, and the device can ensure the stability of the shearing process even when working at high altitudes. This design not only improves the safety of the shearing operation, but also greatly reduces the risk of accidents caused by unstable equipment.

[0050] During the cutting process, the device uses the drive assembly to achieve automatic cutting. The dynamic shearing groove on the rotating panel cooperates with the static shearing groove to achieve precise cutting by gradually approaching the cable. The drive assembly not only provides powerful cutting power, but also can realize the automatic reset function after cutting. This setting reduces manual intervention and improves overall work efficiency. At the same time, the multi-stage gear reduction system amplifies the shearing torque, allowing the device to easily cut thicker cables. This performance is particularly important in emergency repairs and complex line maintenance.

[0051] Compared with traditional manual wire cutting tools, this device significantly reduces labor intensity while improving cutting accuracy and efficiency. Workers can perform high-altitude cutting operations through remote control or ground operation, which is labor-saving and safe. Especially in emergency repair scenarios where power supply needs to be quickly restored, the device demonstrates efficient working performance. Whether it is urban power grid maintenance, rural power grid transformation, or emergency repair of large transmission lines, this device can provide reliable technical support.

[0052] In addition, this device has strong adaptability and scalability. It is not only suitable for cable cutting in power systems, but also for cutting operations in other scenarios such as communication lines and high-altitude steel cables, and has broad application prospects. Its compact design and reliable performance make it a practical and efficient tool in various high-altitude operations, with significant market value and promotion potential.

[0053] In this process, the staff only needs to simply hold the insulating rod 1 with their hands.

[0054] In this embodiment, the driving assembly 9 includes a driving motor 91, and the driving motor 91 is installed on the surface of the supporting panel 2, and a driving gear 97 is installed at the output end of the driving motor 91. A rolling bearing 96 is provided on the surface of the supporting panel 2, and a rotating rod 98 is rotatably connected inside the rolling bearing 96, a first transmission gear 94 is installed at 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 provided on the outer arc surface of the rotating panel 8, and the second transmission gear 95 is meshed and connected with the transmission tooth groove 93. 92 is also provided between 91 and 2.

[0055] The driving motor 91 is mounted on the surface of the supporting panel 2, and its output end transmits power to the rotating rod 98 inside the rolling bearing 96 through the driving gear 97. One end of the rotating rod 98 is connected to the first transmission gear 94, and the first transmission gear 94 drives the second transmission gear 95 meshed 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, so as to realize the stable rotation of the rotating panel 8 around the connecting bolt 12.

[0056] The rolling bearing 96 in the transmission process reduces friction and ensures the smooth rotation process. At the same time, the transmission design of the multi-stage gear optimizes the power distribution and improves efficiency. The entire structure is compact, and the movement trajectory of the rotating panel is controlled by precise meshing, making the cutting 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 cable cutting tasks of different sizes and strengths.

[0057] In this embodiment, a housing 4 is disposed 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 driving 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 disposed on the surface of the control box 6.

[0058] This design effectively protects the transmission structure from the influence of the external environment, such as dust, rain and other impurities, and enhances the durability and working reliability of the device. The closed structure of the housing 4 can also play a role in supporting and fixing various components, ensuring the accurate position of the gears and rotating panels during operation, and improving the efficiency and stability of the transmission.

[0059] The control box 6 mounted on the surface of the support panel 2 is used to accommodate the control system. A battery pack 5 is arranged outside the control box. The battery pack serves as the power source of the drive assembly and provides stable power for the drive motor 91 and other electrical components. The design of the control box 6 allows the operator to centrally control the various functions of the device and operate the device through the control box, which is simple, intuitive and efficient. The layout of the housing 4 and the control box 6 is reasonable, making the overall structure compact and the weight evenly distributed, which is easy to carry and can ensure the stability and safety of operation during high-altitude operations.

[0060] like Figure 1-Figure 5 As shown, in one embodiment of the present invention, a mounting base 13 is provided on the surface of the supporting panel 2 facing away from the rotating panel 8, and a current sensor 7 is mounted on the surface of the mounting base 13, and the shape of the current sensor 7 is U-shaped.

[0061] In this embodiment, when the device is mounted on the wire, the U-shaped current sensor 7 can surround the wire in its sensing area and detect the current in the wire through the principle of electromagnetic induction. When the current sensor 7 detects that there is current in the wire, it transmits a signal to the control module, and the control module prohibits the drive component from starting to avoid cutting the wire in a live state, thereby ensuring the safety of the operator. If the current sensor 7 detects that there is no current in the wire, the control module allows the drive component to enter the working state and start the cutting operation.

[0062] This design realizes intelligent judgment of the cutting operation, avoids the risk of live cutting due to misoperation, and improves the safety performance of the device. The current sensor 7 is U-shaped, which can ensure full coverage of the wire and improve the accuracy of current detection. At the same time, it has a compact and lightweight structure and does not increase the overall weight and volume of the device. By detecting the current, the device can effectively judge the working state of the wire before cutting, solving the problem that traditional wire cutting devices cannot judge whether it is energized or not and there is a high risk of electric shock. This design makes the device particularly suitable for the maintenance and repair of high-altitude power lines, which improves safety while reducing misoperation and improving efficiency and reliability.

[0063] In one embodiment of the present invention, there is also provided an operating method of an intelligent safety wire breaking shearing device, the method specifically comprising the following steps:

[0064] S1: Device Installation

[0065] Fix the support panel 2 to one end of the insulating rod 1 by bolts, and check whether the housing 4 on the support panel 2 is well sealed to ensure that the device is in a stable state;

[0066] S2: Mount operation

[0067] The operator holds the insulating rod 1 and lifts the device above the conductor 3 so that the static shear groove 10 on the supporting panel 2 is hung on the conductor 3;

[0068] S3: Current detection

[0069] Start the current sensor 7, which surrounds the wire 3 with its U-shaped structure to detect whether the wire 3 is charged. If the current sensor 7 detects that there is current in the wire 3, the control box 6 prohibits the drive component 9 from starting. If it is detected that there is no current in the wire 3, the next step of operation is allowed;

[0070] S4: Drive start

[0071] The operator starts the driving assembly 9 through the control box 6, and the driving motor 91 drives the first transmission gear 94 meshed with it to rotate through the driving gear 97, and the first transmission gear 94 then drives the second transmission gear 95 meshed with it to rotate, and the second transmission gear 95 finally drives the transmission tooth groove 93 on the outer arc surface of the rotating panel 8 meshed with it to rotate;

[0072] S5: Cutting action

[0073] Under the action of the driving assembly 9, the rotating panel 8 rotates around the connecting bolt 12, and the dynamic shearing groove 11 gradually approaches the static shearing groove 10 and the conductor 3. When the dynamic shearing groove 11 and the static shearing groove 10 squeeze the conductor 3, the shearing operation of the conductor 3 is completed;

[0074] S6: Shear reset

[0075] After the shearing is completed, the driving assembly 9 controls the rotating panel 8 to return to the initial position, so that the dynamic shearing groove 11 and the static shearing groove 10 are separated 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 in the protection scope of the present invention.
