[0002] In the power system, 10kV distribution lines are a key component to ensure stable power supply to the majority of users, so the efficiency and safety of their maintenance and repair work are particularly important. When it comes to the removal and reconnection of the 10kV line tension pole drainage wire, both traditional wire cutters and existing electric integrated high-voltage wire cutters have exposed some obvious limitations.

[0003] The design of traditional wire cutters only allows cutting operations from the bottom up or perpendicular to the wire. This single operation mode limits the flexibility of the operation in practical applications, especially when the cutting angle needs to be precisely adjusted according to different on-site environments. The inability to operate at multiple angles not only increases the technical difficulty of construction, but also increases the safety risks faced by workers. In addition, when using such tools to cut wires, due to stress, the two ends of the cut wires may suddenly bounce off, posing a risk of electric shock to nearby workers. Moreover, considering the inconvenience of using these tools, it is usually necessary for multiple workers to work together, which undoubtedly prolongs the time of the entire maintenance process and increases the labor intensity.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1, reference Figure 1 , which is the first embodiment of the present invention, and provides a live cable cutting mechanism, comprising a sharp-surface wire-cutting unit 100, comprising a first sharp block 101, a second sharp block 102 arranged parallel to one side of the first sharp block 101, a plurality of groups of bending blocks 103 arranged at upper and lower sides of the first sharp block 101 and the second sharp block 102, a pressing member 104 arranged inside each group of bending blocks 103, and a feeding member 105 arranged at the rear end of the first sharp block 101;

[0040] The bending block 103 is hollow inside, and the opening is in an arc-shaped inward bend;

[0041] The pressing member 104 is an elastic member and is bent relatively inward.

[0042] It should be noted that the first sharp block 101 and the second sharp block 102 have the same structure, and the wire-breaking surfaces are sharp surfaces with the same angle, which can cut the cable under pressure.

[0043] Preferably, the first sharp block 101 and the second sharp block 102 are made of high-strength alloy steel, which has strong shearing ability and durability, ensuring safe and effective operation under high pressure environment. The blade thickness angle at the sharp surface is moderate, ensuring the quality of the blade, the overall stability and durability of the cutting, making the axe more stable when in use, reducing the risk of blade breakage, and making it easier to cut into objects, reducing the force required, and improving cutting efficiency.

[0044] Preferably, the first sharp block 101 and the second sharp block 102 are located on the same plane, ensuring that the stress generated on both sides of the cable after cutting will be evenly diffused to both sides of the cable, so that the pressing members 104 on the upper and lower sides of the first sharp block 101 and the second sharp block 102 can exert the same force on the cable. The bending member 103 will always exert an inward force on the pressing member 104. It can always exert force on the cable to prevent the cable from breaking during the cutting process.

[0045] Preferably, the pressing member 104 is elastic and can play a good role in limiting and clamping the cable.

[0046] Preferably, the bending member 103 has an additional inward force, and the pressing member 104 is elastic, which can better fit the limit cable. The bending member 103 can be in the form of a limit slot, and the pressing member 104 is in the form of an elastic baffle; or the bending member 103 is in the form of a tension spring limit, and the pressing member 104 is in the form of a spring telescopic rod. The feeding member 105 is a linear moving module, specifically a hydraulic rod.

[0047] In the cable cutting device provided in this embodiment, the cooperation between the first sharp block 101 and the second sharp block 102 is the key to the entire mechanism. The bending pieces 103 arranged on both sides not only provide the necessary support for the overall structure, but more importantly, they form a dynamic adjustment system with the pressing piece 104. As the feeding piece 105 gradually pushes the first sharp block 101 toward the second sharp block 102 for the shearing operation, during this process, the bending piece 103 applies continuous and uniform pressure to the pressing piece 104, prompting the latter to expand outward in a direction perpendicular to the cable. Such a design cleverly increases the clamping force of the pressing piece 104 on the cable to be cut, thereby ensuring that the cable can be firmly fixed during the entire cutting process, greatly reducing the risk of inaccurate cutting or accidental injury caused by cable movement.

[0048] In addition, after the shearing action is completed, when the first sharp block 101 begins to withdraw away from the second sharp block 102, the pressing member 104, which was originally expanded by the external force, will naturally return to its initial state, that is, shrink inward. The important thing in this process is that even before the first sharp block 101 completely leaves, the pressing member 104 can still maintain effective control over the broken cable portion, avoiding any situation that may cause electrical failures such as short circuits. Only after the first sharp block 101 completely leaves the contact area will the pressing member 104 release the restriction on the cable, allowing the subsequent processing steps to proceed smoothly.

[0049] In summary, this design not only improves the accuracy and efficiency of cable cutting operations, but also significantly enhances the safety during the operation, effectively prevents various accident risks caused by cutting live cables, and effectively avoids short-circuit accidents caused by broken cables contacting cutting tools or other conductors. At the same time, it also helps to keep the work area clean and tidy, providing convenient conditions for subsequent processing or maintenance.

[0050] Example 2, reference Figure 1 to Figure 3 , which is the second embodiment of the present invention, and is different from the first embodiment in that it includes a sharp surface breaking unit 100, including a first sharp block 101, a second sharp block 102 arranged parallel to one side of the first sharp block 101, a plurality of groups of bending blocks 103 arranged at the upper and lower sides of the first sharp block 101 and the second sharp block 102, a pressing member 104 arranged inside each group of bending blocks 103, and a feeding member 105 arranged at the rear end of the first sharp block 101;

[0051] The bending block 103 is hollow inside, and the opening is in an arc-shaped inward bend;

[0052] The pressing member 104 is an elastic member and is bent relatively inward.

[0053] Furthermore, the first sharp block 101 includes a first shearing end 101a at its front end and a docking groove 101b disposed at its rear end;

[0054] The second sharp block 102 includes a second shearing end 102a at its front end and a fixing groove 102b disposed at its rear end;

[0055] The fixing groove 102b is keyed into the fixing member.

[0056] Furthermore, the bending block 103 includes a parallel groove 103a fixedly clamped on the first sharp block 101, and a bending groove 103b arranged at the front end of the parallel groove 103a.

[0057] Furthermore, the bending groove 103b includes an outwardly inclined arc groove 103b-1 on its inner side, and an inwardly inclined arc groove 103b-2 connected to the outwardly inclined arc groove 103b-1;

[0058] The front end of the pressing member 104 is an arc end 104a, and the pressing member 104 is bent inward at the inward arc groove 103b-2.

[0059] It should be noted that the bending block 103 in this embodiment is hollow inside, and the opening is an arc-shaped inward bend; the pressing piece 104 is an elastic piece, and the bending direction is relatively inward. The bending block 103 is a limiting slot, and the first sharp block 101 and the second sharp block 102 have the same structure, and the first sharp block 101 is composed of a first shearing end 101a at its front end and a docking groove 101b arranged at its rear end; similarly, the second sharp block 102 is composed of a second shearing end 102a at its front end and a fixing groove 102b arranged at its rear end. The first sharp block 101 and the second sharp block 102 are both made of high-strength alloy steel, and the docking groove 101b at the rear end is threadedly connected to the feed piece 105, and the connection part at the front end of the feed piece 105 is made of insulating material to avoid short circuit of the equipment connection.

[0060] The difference is that the keyway of the fixing groove 102b is connected to the fixing member, and the fixing member can effectively limit the second sharp block 102, and the first sharp block 101 is driven by the feeding member 105 to move toward the second sharp block 102. Compared with the simultaneous inward movement of two sets of shearing surfaces, the structure of unilateral movement is simpler, and only one set of driving mechanism is needed to move one of the shearing blocks, while the other remains fixed. This can reduce the cost and complexity of the entire device and may reduce maintenance requirements. In addition, when only one side of the shearing block is active, it is easier to control its movement path and final position, which helps to achieve a more accurate shearing point. In addition, the fixed shearing block provides a stable reference point for aligning the material to be sheared, which helps the bending member 103 to press the pressing member 104 to limit the cable. The unilateral movement design usually produces a smaller initial impact force because it only needs to overcome half of the resistance to start working. The simultaneous advancement of both sides may increase the risk of damage to the cable or equipment due to the instantaneous application of greater pressure. It can also improve safety. If both sides are in a dynamic state, there may be a risk of misoperation, such as the failure of the two shearing surfaces to be completely closed. In contrast, in the unilateral movement mode, only one part is movable, reducing the possibility of accidental injury due to equipment failure.

[0061] Better, such as Figure 2, the bending block 103 is a limiting slot hole, and the pressing piece 104 can be inserted into it. Specifically, the bending block 103 is composed of a parallel slot 103a parallel to the first sharp block 101 or the second sharp block 102, and a bending slot 103b at the front end of the parallel slot 103a. The parallel slot 103a is fixedly connected to the upper and lower surfaces of the first sharp block 101 or the second sharp block 102 by riveting, and its vertical cross-section is rectangular, which is convenient for inserting the pressing piece 104. The bending slot 103b is composed of an outward arc slot 103b-1 and an inward arc slot 103b-2 connected to the outward arc slot 103b-1. The outward arc slot 103b-1 is bent outward, changing the path of the pressing piece 104 that was originally attached to the pressing piece 104 outward, and the inward arc slot 103b-2 is bent inward in the slot path that was originally bent outward, and the pressing piece 104 is finally deflected inward.

[0062] The bending groove 103b not only enhances the guiding effect on the pressing piece 104, but also limits the position of the pressing piece 104 during the entire shearing process, thereby ensuring effective clamping and safe control of the cable. When the first sharp block 101 approaches the second sharp block 102, the pressing piece 104 will be affected by the bending groove 103b and spread outward; and when the first sharp surface 101 retreats, the pressing piece 104 will be redirected to the inside until the constraint on the cable is completely released. Such a mechanism effectively prevents the accidental bouncing of the cable after shearing and the safety problems that may arise, and improves the safety and reliability of the entire operation process.

[0063] Preferably, the pressing piece 104 is designed with an elastic rectangular steel sheet and is connected to the bending block 103 by plugging. This connection method is not only stable and reliable, but also convenient for later maintenance and replacement. Specifically: the pressing piece 104 uses a rectangular steel sheet with high elasticity to ensure that it can provide sufficient pressure during the shearing process, and can return to its original state after being stressed, so as to maintain stable performance under long-term use. The pressing piece 104 is installed in the limiting slot of the bending block 103 by simple plug-in. This method not only simplifies the assembly process, but also allows maintenance personnel to quickly and conveniently perform inspection or replacement operations without the need for complex tools or techniques.

[0064] Preferably, the front end of the pressing member 104 is a rounded end 104a. The rounded end 104a can effectively reduce the possibility of the pressing member 104 getting stuck on the rubber sheath of the cable when cutting the cable, ensuring smooth movement even when handling cables with complex insulation layers. The rounded edges help reduce the risk of damage to the cable surface, while reducing friction, allowing the pressing member 104 to perform its pressing and releasing actions more smoothly. By eliminating sharp corners, the rounded end 104a also improves the safety of the entire device and reduces the risk of operator injury.

[0065] Example 3, reference Figure 4 , Figure 5 and Figure 7 , which is the third embodiment of the present invention, and is different from the first two embodiments in that it also includes a connecting unit 200, including a connecting seat 201 arranged at its end, and an insulating rod 202 arranged at the bottom of the connecting seat 201;

[0066] The feeding unit 300 includes a pressure sensor 301, a processing module 302 disposed at the front end of the pressure sensor 301, an execution module 303 disposed at one side of the processing module 302, a driving block 304 disposed inside the execution module 303, and a protection block 305 disposed outside the processing module 302;

[0067] Battery box 400;

[0068] Remote control module 500.

[0069] It should be noted that if Figure 4 As shown, the feeding unit 300 is connected to the rear side of the feeding member 105, and the connecting unit 200 is connected to the bottom of the feeding unit 300. The feeding unit 300 is composed of a pressure sensor 301, a processing module 302 arranged at the front end of the pressure sensor 301, an execution module 303 arranged at one side of the processing module 302, a driving block 304 arranged inside the execution module 303, and a protection block 305 arranged outside the processing module 302.

[0070] Preferably, the battery box 400 has a high capacity and a strong endurance. Because it takes into account the selection of output voltage and current, it can provide stable and accurate voltage and current output, ensuring compatibility with various tools in the disconnection tool set; considering the endurance, the power supply module adopts high energy density battery technology for the characteristics of long-term outdoor operations, which not only has a light size and weight, but also provides a long endurance. When fully charged, the module can continuously supply power for several hours or even longer to meet the needs of continuous operation. In addition, the outer shell is made of sturdy and durable materials, which can protect the internal circuit from impact and vibration, and withstand adverse weather conditions. Allow operators to quickly disassemble and assemble, which is convenient for transportation and storage.

[0071] Preferably, the remote control module 500 is mainly responsible for issuing and transmitting instructions. After the drainage line is connected, it needs to be remotely controlled to cut the drainage line. Radio frequency communication technology is used to realize wireless long-distance signal transmission, and the data signal is converted into a form suitable for wireless transmission. The processing module 302 restores the signal through demodulation technology. This module can increase the data transmission rate, has a wide coverage range, can communicate freely on the move, and ensures the efficiency of disconnection.

[0072] After receiving the remote control signal, the signal needs to be restored, which involves demodulation technology, which is mainly used in the PCM / FM system. The PCM / FM radio frequency signal generated by the remote control module 500 is converted to zero intermediate frequency, and then the signal is sent to the processing module 302 for subsequent processing such as demodulation. Its working principle is: during the transmission process, FM modulation is mainly responsible for the SOC baseband processing module, and the modulated signal will be sent to the AD9361 processing module for further up-conversion and other operations to generate a radio frequency signal suitable for antenna transmission. As for the receiving process, once the system receives the radio frequency signal, it will send the signal to the AD9361 processing module for a series of processing steps such as down-conversion and analog-to-digital conversion, so as to obtain a baseband signal that can be further processed by the SOC baseband processing module. In the SOC baseband processing module, the signal will undergo multi-symbol detection demodulation and bit synchronization processing, and finally output the recovered data. According to the instructions from the processing module 302, the corresponding actions are executed to reach the execution module 303, and the drainage line can be effectively cut. The pressure sensor 301 can monitor the pressure inside the system according to the preset pressure range, and keep the pressure within the set range by adjusting the valve. The pressure sensor 301 monitors the pressure change through the sensor, the signal amplifier and the processor process the signal, the controller outputs the control signal according to the comparison result between the set pressure and the actual pressure, the actuator adjusts the valve opening, and the feedback system realizes the automatic adjustment of the pressure.

[0073] Example 4, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention, is different from the first three embodiments in that it includes a connecting seat 201 including a T-block 201a fixedly connected to the bottom of the processing module 302, and a clamping block 201b arranged at the bottom of the T-block 201a.

[0074] Furthermore, the clamping block 201b includes a first clamping surface 201b-1 and a connecting groove 201b-2 disposed inside the first clamping surface 201b-1.

[0075] Furthermore, the insulating rod 202 includes a clamping end 202a disposed at an end thereof;

[0076] The clamping end 202a includes a second clamping surface 202a-1 disposed at one side of the first clamping surface 201b-1, a connecting hole 202a-2 disposed at one side of the second clamping surface 202a-1, and a connecting member 202a-3 disposed at one side of the connecting hole 202a-2.

[0077] Furthermore, the first clamping surface 201b-1 matches with the second clamping surface 202a-1 and can be clamped at multiple angles.

[0078] Furthermore, the protection block 305 is J-shaped, and a key slot 305a is provided in the arc segment;

[0079] The key slot 305a is fitted and connected with the fixing member 305b.

[0080] It should be noted that if Figure 6 As shown, this group of connecting seats 201 are threadedly connected at the bottom of the processing module 302, and the connecting seat 201 and the insulating rod 202 are clamped together by the ratchet surface, thereby realizing the angle adjustment function between the connecting unit 200 and the feeding unit 300, to achieve multi-angle shearing tasks and adapt to more construction operation environments.

[0081] Preferably, the connection base 201 is composed of a T-shaped block 201a connected to the processing module 302, and a clamping block 201b of an integral structure of the T-shaped block 201a, and the clamping block 201a is composed of a first clamping surface 201b-1 and a connection groove 201b-2 provided inside the first clamping surface 201b-1. The structure of the clamping end 202a at the end of the insulating rod 202 is consistent with that of the clamping block 201b, and the two cooperate to achieve the limiting effect after the angle is adjusted.

[0082] Preferably, the connecting member 202a-3 is a high-strength fish bolt, which can be used to adjust the distance between the clamping block 201b and the clamping end 202a, and further adjust the limiting effect therebetween.

[0083] Preferably, the first clamping surface 201b-1 and the second clamping surface 202a-1 have the same structure, both of which are side ratchet discs, and the connecting groove 201b-2 and the connecting hole 202a-2 are threaded holes with the same aperture. When in use, the first clamping surface 201b-1 and the second clamping surface 202a-1 are released from the ratchet meshing state by rotating the connecting member 202a-3, and then the angle of the insulating rod 202 is manually adjusted to achieve the angle adjustment of the feeding unit 300. Not only does it provide a flexible angle adjustment function, but it also ensures stability and reliability during operation. Through simple rotation and manual adjustment, the operator can easily adjust the angle of the tool according to actual needs, improve work efficiency and ensure the safety of operation.

[0084] By using the design in which the first clamping surface 201b-1 and the second clamping surface 202a-1 are clamped together, compared with the general ratchet limit mechanism, the advantage of this design is that the ratchet engagement state can be easily released by rotating the connecting piece 202a-3, and the angle of the insulating rod 202 can be manually adjusted and then re-locked. The whole process is simple and fast, without the need for complicated tools or steps. And the engagement between the ratchet discs provides a stable connection to ensure that there will be no accidental loosening or sliding during operation. When subjected to large torque or external force, it can still maintain good stability, enhancing the overall reliability and durability of the tool. The meshing structure of the ratchet disc can be firmly locked at any predetermined angle position to prevent safety risks caused by unstable angles. In addition, in high-risk working environments, it can provide higher safety guarantees and reduce accidents caused by tool slippage or instability.

[0085] The other structures are the same as those in Embodiments 1 to 3 and will not be described in detail here.

[0086] In summary, the device is designed with an elastic pressing piece 104 and an arc end 104a to effectively prevent the wire from bouncing off after shearing, significantly reducing the risk of electric shock. Multi-angle adjustment is achieved with the cooperation of the first clamping surface 201b-1 and the second clamping surface 202a-1, so that the tool can adapt to complex environments, improve operational flexibility and safety, and reduce technical difficulty and operation time. In addition, the shearing accuracy is improved, and the multi-angle adjustment allows the user to adjust the optimal shearing angle according to specific needs, thereby improving the shearing accuracy, reducing damage to the wire, and extending the service life of the wire. Precise shearing can be completed by a single person, reducing the need for collaborative work, simplifying the work process, and improving overall work efficiency. At the same time, communication errors and safety hazards that may be caused by multi-person collaboration are reduced.

[0087] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
