[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, an embodiment of the present invention provides a power transmission and distribution line disconnection quick connection clamp, which includes a housing 10, an upper cover 20, a wire clamp 30 and a locking member 40. The housing 10 has two through-holes 11 arranged at intervals along its circumference. The upper cover 20 is arranged on the housing 10 in a liftable manner, and the portion of the upper cover 20 extending into the housing 10 is provided with a wire clamp 21 capable of pressing a cable. The wire clamp 30 is arranged in the housing 10, and the wire clamp 30 has a wire clamp hole 31 arranged corresponding to the through-hole 11. The wire clamp 30 has a wire clamping state in which the wire clamp hole 31 is used to clamp the cable and a separation state in which the wire clamp hole 31 releases the cable. The upper cover 20 is driven and connected to the wire clamp 30. When the upper cover 20 is lifted or lowered relative to the housing 10, the upper cover 20 drives the wire clamp 30 to switch between the wire clamping state and the separation state. The locking member 40 is disposed between the housing 10 and the upper cover 20 , and the locking member 40 can lock the relative positions of the upper cover 20 and the housing 10 .

[0033] When using the power transmission and distribution line disconnection quick connection clamp provided in this embodiment, when connecting the disconnection, first insert the two disconnected cables into the through-holes 11 on the shell 10 respectively, and then press the upper cover 20 downward, and the cable can be pressed and fixed by the wire pressing member 21 of the upper cover 20, and since the shell 10 is provided with a wire clamping member 30, the cable can also be clamped and fixed by the wire clamping member 30, so as to further improve the fixing effect of the cable. After completing the fixing of the cable, the position of the upper cover 20 is locked by the locking member 40 to prevent the two cables from separating. In addition, when the upper cover 20 is raised or lowered relative to the shell 10, the upper cover 20 drives the wire clamping member 30 to switch between the wire clamping state and the separation state, which can simplify the driving structure of the power transmission and distribution line disconnection quick connection clamp.

[0034] This design not only allows the disconnected wires to be quickly connected, but also provides stable mechanical support during the connection process to prevent the cables from falling off in high-voltage environments. It is suitable for various emergency repair and daily maintenance scenarios, significantly improving the operating efficiency and safety of the power system. In actual applications, this design enables workers to respond quickly to sudden disconnections and reduce power outages, especially in high-voltage transmission networks. Its fast and effective connection capabilities can greatly reduce economic losses and safety risks caused by disconnections.

[0035] like Figure 3 As shown, the wire clamping member 30 includes an upper pressure sleeve 32, a lower pressure sleeve 33 and a transmission member 34. The upper pressure sleeve 32 and the lower pressure sleeve 33 are both arc-shaped plates. The upper pressure sleeve 32 and the lower pressure sleeve 33 are spliced ​​together to form a wire clamping hole 31. The upper cover 20 can be driven and connected with the upper pressure sleeve 32 and the lower pressure sleeve 33 through the transmission member 34, so that the upper pressure sleeve 32 and the lower pressure sleeve 33 move relative to each other, so that the wire clamping member 30 switches between the wire clamping state and the separation state. This structural design can ensure that the cable is evenly clamped in the wire clamping hole 31, avoiding cable damage caused by excessive local pressure. At the same time, in the separation state, the cable can be easily released, which is convenient for rapid replacement and adjustment under different cable diameters and materials. It is widely used in disconnection connections in power transmission lines, substations, power facilities and other occasions.

[0036] In the daily maintenance of the power system, this flexible structural design can greatly improve work efficiency, especially in scenarios where frequent adjustments or replacements of cables are required, such as equipment updates in substations. Its advantages are more obvious, not only reducing the physical labor of staff, but also reducing the risk of secondary damage caused by improper operation.

[0037] like Figure 3As shown, the transmission member 34 includes a first threaded sleeve 341, a movable plate 342 and a bidirectional screw 343. The first threaded sleeve 341 is movably arranged on the inner wall of the housing 10 in the vertical direction. The upper pressing sleeve 32 of the movable plate 342 is connected to the upper cover 20, and the lower pressing sleeve 33 is connected to the movable plate 342. The bidirectional screw 343 is rotatably connected to the upper cover 20. The bidirectional screw 343 has a first thread segment 3431 and a second thread segment 3432 with opposite thread rotation directions. The first thread segment 3431 is threadedly connected to the first threaded sleeve 341, and the second thread segment 3432 is threadedly connected to the movable plate 342. Through the rotation of the bidirectional screw, the moving distance of the upper pressing sleeve and the lower pressing sleeve can be accurately controlled, so as to achieve adaptive connection of cables with different diameters. At the same time, the self-locking thread design of the bidirectional screw can prevent loosening caused by vibration under high voltage current, ensure the stability and reliability of the connection, and is suitable for high-load and high-vibration power transmission environments.

[0038] This precise adjustment capability is particularly important in high-load power transmission, which can effectively avoid power fluctuations caused by loose connections and provide a solid foundation for the stable operation of the power grid. Especially in the transmission of renewable energy such as wind power generation and hydropower generation, it is more sensitive to vibration and load changes. The self-locking design of the bidirectional screw can significantly improve the adaptability and durability of the connection clamp.

[0039] Specifically, the first threaded sleeve 341 can only move in the vertical direction along the housing 10 and cannot rotate relative to the housing 10. That is, a rotation-stopping structure is provided between the first threaded sleeve 341 and the housing 10.

[0040] like Figure 3 As shown, the transmission member 34 includes two bidirectional screws 343 and two first threaded sleeves 341 corresponding to each other. The lower ends of the two bidirectional screws 343 are respectively threadedly connected to the two ends of the movable plate 342, and a wire clamping member 30 is provided at each through-hole 11. This dual transmission design improves the synchronization and accuracy of the wire clamping member action, ensures the centering and stability of the cable during the connection process, and is suitable for power systems that require high-precision connection, such as high-voltage transmission lines, power supply lines for precision electronic equipment, etc.

[0041] In the maintenance of high-voltage transmission lines, this high-precision connection method can ensure the continuity and stability of current transmission. For the power supply of precision electronic equipment, it avoids equipment failures caused by unstable connections and ensures the overall performance and reliability of the power system.

[0042] like Figure 1 and Figure 4As shown, the locking member 40 includes a locking rod 41, on which a locking external thread is provided, the housing 10 has a first threaded hole 12, and the upper cover 20 has a second threaded hole 22 provided corresponding to the first threaded hole 12, and the locking rod 41 can be threadedly connected with the first threaded hole 12 and the second threaded hole 22 through the locking external thread. The setting of the locking rod enables the connecting wire clamp to be firmly locked after the cable connection is completed, preventing the connection from being loosened due to external force in bad weather or long-term operation, and is suitable for power line maintenance in various extreme environments, such as emergency repairs after natural disasters such as typhoons, earthquakes, ice and snow.

[0043] Under extreme environmental conditions, the stability of the locking rod is particularly critical. It can ensure the rapid recovery of power lines after natural disasters such as strong winds and earthquakes, reduce the power outage time caused by natural disasters, and ensure the continuity of power supply.

[0044] Furthermore, when in use, the locking rod 41 is pulled and twisted so that the upper and lower pressing sleeves clamp the wires. Since the locking rod 41 is small in size and is not easily affected by external factors, the wires will not be released due to accidental touch during use, and the device has good stability.

[0045] The process of adjusting the upper cover to move downward and lock it is that the locking rod is fully inserted into the interior of the upper cover to lock the upper cover. At this time, the locking rod can move up and down inside the shell and drive the upper cover to move up and down inside the shell. When the upper cover moves to the appropriate position, the user twists the locking rod to connect the locking rod to the upper cover and the shell at the same time. At this time, the movement and locking of the upper cover are completed.

[0046] like Figure 1 As shown, the upper end of the housing 10 is provided with a second threaded sleeve 13 and at least two connecting ribs 14, the at least two connecting ribs 14 are arranged at intervals along the circumference of the housing 10 and extend along the radial direction of the housing 10, one end of the at least two connecting ribs 14 are connected to the housing 10, and the other end of the at least two connecting ribs 14 are connected to the second threaded sleeve 13, and the first threaded hole 12 is provided on the second threaded sleeve 13. The combination of the connecting rib and the second threaded sleeve not only enhances the structural strength of the housing, but also provides a more stable connection point for the locking rod, which is suitable for disconnection connection of power facilities that need to withstand large mechanical loads, such as large transformers, high-voltage switch cabinets, etc.

[0047] This structural reinforcement measure enables the wire clamp to maintain good structural stability when subjected to high voltage current and mechanical loads. It plays a more significant role in the maintenance of large power facilities, such as the internal line connection of large transformers, ensuring the safe operation and efficient maintenance of power equipment.

[0048] like Figure 5As shown, the power transmission and distribution line disconnection quick connection clamp also includes a connector 50 and an elastic reset member 60. The shell 10 is rotatably connected to the connector 50. The rotation axis of the shell 10 extends vertically. The elastic reset member 60 is respectively connected to the connector 50 and the shell 10. The connector 50 has an external connection portion.

[0049] Specifically, the connector 50 includes a connecting tube 51 and a connecting seat 52. The upper end of the connecting tube 51 is an open structure. A guide rail 15 is provided at the lower edge of the shell 10. The upper end of the connecting tube 51 is slidably connected to the guide rail 15. The lower end of the connecting tube 51 is connected to the connecting seat 52. The external connection part is provided on the connecting seat 52. The lower end of the shell 10 has a mounting column 16 extending downward. The elastic reset member 60 is a torsion spring 61. The torsion spring 61 is sleeved on the mounting column 16 and is located in the connecting seat 52. The two ends of the torsion spring 61 are respectively connected to the shell 10 and the connecting seat 52. The combination of the connecting tube and the connecting seat not only provides a stable interface between the connecting wire clamp and the external device, but also can automatically adjust the state of the connecting wire clamp through the elastic action of the torsion spring, thereby ensuring the tightness and reliability of the cable connection.

[0050] During use, under normal conditions, the plastic elastic force of the torsion spring continuously pulls the wires at both ends, causing the entry portion to be bent. If the wires at both ends are affected by external factors as a whole, such as accidental touch, the tension changes and becomes tight, the tension at both ends drives the shell to rotate along the guide rail as a whole, causing the wires at both ends to change from a bent state to a straight state, thereby offsetting part of the effect of the tension change and avoiding secondary breakage of the wires.

[0051] By arranging a torsion spring, the wires at both ends are in a bent and connected state. Therefore, when the wires are tightened, the torsion springs are naturally pulled, thereby avoiding secondary damage to the wires.

[0052] A mounting plate 19 is provided at the bottom of the housing 10 , and one end of the torsion spring 61 is connected to the mounting plate 19 .

[0053] like Figure 1 As shown, at least two elastic members 18 are arranged on the inner wall of the through hole 11, and at least two elastic members 18 are arranged at intervals along the circumference of the through hole 11. The arrangement of the elastic members can provide additional clamping force when the cable is inserted into the through hole, ensuring the stability of the cable in the clamping hole.

[0054] The wire pressing member 21 is a wire pressing plate 211. The use of the wire pressing plate can distribute the pressure more evenly, avoid excessive stress on the local part of the cable, and is suitable for connecting cables of various types and sizes, such as copper wires, aluminum wires, optical fiber wires, etc.

[0055] When connecting different types of cables, the combined design of elastic parts and wire clamping plates can ensure stable connection of cables under various environmental conditions. Especially in the connection of special cables such as optical fiber cables, the requirements for pressure and clamping force are more stringent. This design can effectively avoid cable damage and ensure the continuity and stability of signal transmission.

[0056] like Figure 1 As shown, heat dissipation ribs 17 are provided on the outer wall of the housing 10. The design of the heat dissipation ribs can effectively improve the heat dissipation performance of the connecting wire clamp, prevent the connection failure caused by excessive temperature during the transmission of large currents, and is suitable for high-load power transmission systems, such as large industrial power facilities, power supply of data centers, etc.

[0057] In high-load power transmission, the design of heat dissipation ribs is crucial to the performance of connecting wire clamps. They can dissipate the heat generated during the connection process in time, avoiding aging of insulation materials and connection failure due to overheating.

[0058] In this embodiment, the clamping surfaces of the upper and lower pressure sleeves are provided with anti-skid patterns; the thread of the bidirectional screw is designed as a self-locking thread; the material of the coating shell is a high temperature resistant and anti-aging plastic; the structural design of the guide rail is a double-track guide; and the pull rod of the adjustment member is provided with an anti-skid handle. These detailed designs not only improve the service life and operational safety of the connecting wire clamp, but also enable operators to easily and accurately complete the disconnection connection task in harsh environments, and are suitable for power maintenance operations under various extreme conditions, such as high temperature, humidity, and corrosive environments. In power maintenance operations under extreme conditions, the importance of these detailed designs cannot be ignored. The anti-skid patterns and anti-skid handles ensure that operators can operate accurately even when they are slippery or wearing gloves, and the design of the high temperature resistant and anti-aging plastic coating shell and the self-locking thread enables the connecting wire clamp to maintain good performance in high temperature, humidity, and corrosive environments, prolonging its service life and reducing maintenance costs, providing reliable guarantees for the continuous operation of power facilities in harsh environments.

[0059] Working principle:

[0060] The specific process of fixing the wires is that when the upper cover moves downward, the upper pressure sleeve is synchronously driven to move downward. Since the first threaded sleeve is screwed to the outside of one of the threaded wires of the bidirectional screw, when the upper cover moves downward, the first threaded sleeve is synchronously driven to move downward, and the bidirectional screw is rotated. Since the other threaded wire of the bidirectional screw is also screwed with a movable plate, the lower pressure sleeve moves upward during the process and pushes the lower pressure sleeve to move up and down. The lower pressure sleeve and the upper pressure sleeve form a cooperation up and down to clamp and fix the wires. The process of adjusting the upper cover to move downward and lock it is that the locking rod is completely inserted into the interior of the upper cover to lock the upper cover. At this time, the locking rod can move up and down inside the second threaded sleeve and drive the upper cover to move up and down inside the shell. When the upper cover moves to a suitable position, the user twists the locking rod to screw out the end of the locking rod and rotate along the thread line inside the second threaded sleeve. At this time, the movement and locking of the upper cover are completed.

[0061] During use, under normal conditions, the plastic elastic force of the torsion spring continuously pulls the wires at both ends, causing the entry portion to be bent. If the wires at both ends are affected by external forces as a whole, such as accidental touch, and the tension changes and becomes tight, the tension at both ends drives the shell to rotate along the guide rail as a whole, causing the wires at both ends to change from a bent state to a straight state, thereby offsetting part of the effect of the tension change and avoiding secondary breakage of the wires. In the present application, a torsion spring is provided so that the wires at both ends are in a bent connection state. Therefore, when the wires are tightened, the torsion spring is naturally pulled to avoid secondary damage to the wires.

[0062] In summary, the power transmission and distribution line disconnection quick connection clamp of this embodiment, through its carefully designed structure, can not only quickly and stably complete the disconnection connection task, but also has significant advantages in operational flexibility, adaptability, safety, etc., and is a major innovation in the field of power maintenance. Its wide range of application scenarios and outstanding performance will provide a strong guarantee for the stable operation of the power system, and also provide a new solution for the rapid maintenance and installation of power facilities. In actual applications, the connection clamp can also be customized according to the characteristics of different power equipment and lines to meet more complex and specific connection requirements, further improving the overall efficiency and safety of the power system.

[0063] In addition, the lightweight design and easy-to-operate characteristics of the connecting wire clamp also make it show great application potential in emerging power maintenance technologies such as drone inspections and remote maintenance, injecting new vitality into the development of the power industry. In drone inspections and remote maintenance, the lightweight and easy-to-operate characteristics make the connecting wire clamp easier to carry and deploy, especially in difficult-to-reach power facility areas such as mountains, deserts, and offshore wind power platforms. Its superior adaptability and convenience can significantly improve the efficiency of repair and maintenance, reduce the manpower and material costs of the power industry, and promote the intelligent and automated development of power maintenance technology.
