Description

Technical Field

[0001] The invention relates to the technical field of power line clamps, and in particular to a line clamp for live access of conductors of lines of 0.4 kV and below into a split trench. Background Art

[0002] In the process of power production, especially in the operation of grassroots teams, power supply safety and efficiency are of vital importance. With the increase in power demand and the complexity of user access, how to effectively maintain, troubleshoot and connect new lines has become an important technical challenge facing the current industry.

[0003] In actual operations, grassroots power operators often encounter the following technical problems:

[0004] 1. Difficulty in handling line faults: When a short circuit or fault occurs in a user line, the burning or damage of the wire often forces operators to carry out emergency treatment. Traditional means may not be able to respond quickly to user needs, resulting in prolonged power outages.

[0005] 2. New meter access issues: When expanding new installations, meter access often requires wiring, which involves the stability of power supply for large-load users. The use of existing access wire clamps often results in loose connections due to mismatching, increasing the risk of accidents.

[0006] 3. The wire and the clamp do not match: the existing aluminum parallel groove clamp cannot be well combined with wires of different wire diameters in actual use. There are problems such as difficulty in inserting the wires and even difficulty in tightening the bolts. This mismatch not only affects the work efficiency, but also increases the possibility of equipment damage.

[0007] 4. Safety hazards: During the process of line relocation or ignition, the wires on the pole tower are energized, and the access operation will generate a large arc. This requires operators to maintain a sufficient safety distance, but in reality, due to limited operating conditions, operators face potential personal safety risks.

[0008] 5. Limitations of live working: Due to the large uncertain safety risks, operators often do not dare to use live working to deal with the problem of ignition. This is not only inconsistent with the current power department's requirements for power supply reliability and continuous power supply, but also increases the psychological burden of operators.

[0009] In general, the existence of the above problems has brought major challenges to grassroots power operations in dealing with line faults, user access, and operational safety. In the context of new power demand, innovation in operational tools and technical solutions is particularly urgent to improve operational efficiency and ensure the reliability and safety of power supply. Summary of the invention

[0010] In order to solve the above problems, the present invention proposes a wire clamp for live access to a trench for 0.4 kV and below line conductors, which is used to improve the operation method and the use of tools, improve the operation efficiency and reduce the personal safety risks of operators.

[0011] The technical solution adopted by the present invention is:

[0012] Used for live access of conductors in lines of 0.4kV and below into the trench wire clamp, including the wire clamp body and the wire clamp operating device;

[0013] The wire clamp body is a double-groove wire clamp, one side of which can clamp live wires in the wire clamp groove, and the other side of which can clamp newly installed wires in the wire clamp groove. The wires are clamped by the clamp block driven by the screw. A connecting seat for matching the wire clamp operating device is also provided below the wire clamp body.

[0014] The wire clamp operating device is a gun-shaped structure with a manual operating rod assembly and an insulating operating rod assembly. It is detachably connected to the connecting seat below the wire clamp body through the manual operating rod assembly, and is connected to the screw rod through the insulating operating rod assembly. The screw rod is operated by an electric wrench of the insulating operating rod assembly, so that the screw rod drives the clamp block to quickly clamp the live wire.

[0015] Furthermore, the cross-section of the wire clamp body is I-shaped.

[0016] Furthermore, the double-sided wire clamp grooves are both provided with clamping blocks that can movably clamp the wires, and the wire clamp body is provided with screws above and below. The screws extend into the wire clamp grooves and are rotatably connected to the clamping blocks, and the screws are threadedly connected to the wire clamp body.

[0017] Furthermore, the manual operating rod assembly and the insulating operating rod assembly of the wire clamp operating device are arranged in parallel.

[0018] Furthermore, the manual operating rod assembly includes an operating rod, which is hollow inside and provided with a guide rod. The upper end of the guide rod is connected to a connector that cooperates with a connecting seat at the top of the operating rod, and the lower end of the guide rod extends to the outside of the operating rod and is connected to a trigger assembly.

[0019] Furthermore, the connector is plugged and installed on the top of the operating rod, and a locking rod is provided therein. One end of the locking rod extends into the operating rod and is connected to the upper end of the guide rod, and the other end extends into the connecting seat below the wire clamp body and is provided with a locking groove; a connection state maintaining spring mounted on the locking rod is also provided in the connector; a limit rod and a limit lock ball cooperating with the locking rod are provided in the connecting seat below the wire clamp body.

[0020] Furthermore, the trigger assembly includes a trigger mounting seat, which is fixedly mounted on the insulating operating rod of the insulating operating rod assembly and is also fixedly mounted on the lower end of the operating rod; a trigger and a linkage rod are rotatably mounted in the trigger mounting seat, and the trigger is connected to the lower end of the guide rod through the linkage rod; when the trigger is pulled, the guide rod is driven to move through the linkage rod.

[0021] Furthermore, the insulating operating rod assembly includes an insulating operating rod, which is hollow inside and provided with a driving rod, a hexagonal socket is rotatably installed on the top end of the insulating operating rod, and an electric wrench is installed on the lower end; the lower end of the driving rod is connected to the output end of the electric wrench inside the insulating operating rod, and the upper end of the driving rod is fixedly connected to the hexagonal socket inside the insulating operating rod.

[0022] A method for maintaining, troubleshooting and installing new access conductors, the method is based on the above-mentioned live access trenching clamp for conductors of 0.4 kV and below lines, and comprises the following steps:

[0023] Step 1: clamp the newly installed wire through the wire clamp groove on one side of the wire clamp body; since the newly installed wire is not connected to electricity, this process does not require the use of a wire clamp operating device. After the newly installed wire enters the wire clamp groove, the screw on the top of the wire clamp body drives the clamp block to clamp it;

[0024] Step 2, using the wire clamp operating device, connect the manual operating rod assembly of the wire clamp operating device to the connecting seat below the wire clamp body, and at the same time connect the insulating operating rod assembly to the screw rod below the wire clamp body;

[0025] Step 3, using the wire clamp operating device to move the wire clamp body so that the live wire enters the wire clamp groove on the other side of the wire clamp body;

[0026] Step 4, start the electric wrench of the insulating operating rod assembly of the wire clamp operating device, and use the electric wrench to drive the screw under the wire clamp body to rotate, so that the screw under the clamp body drives the clamp block to complete the clamping of the live wire;

[0027] Step 5, operate the trigger of the manual operating rod assembly of the wire clamp operating device. The trigger drives the locking rod in the connector to move through the linkage rod and the guide rod, so that the connector and the connecting seat under the wire clamp body are unlocked. The wire clamp operating device can be separated from the wire clamp body to complete maintenance, troubleshooting and new installation of wire access operations.

[0028] The live access ditch clamp for conductors of lines of 0.4kV and below has the following significant beneficial effects:

[0029] 1. Improved safety: By adopting insulated operating rod assemblies and electric wrenches, the actual contact between operators and live wires is reduced, the risk of electric shock is significantly reduced, and personal injuries such as burns and scalds caused by electric arcs are avoided.

[0030] 2. Improved operating efficiency: The use of double-groove wire clamps and clamping mechanisms reduces manual operation time. Especially when facing live wires, operators can complete clamping more quickly, improving overall operating efficiency.

[0031] 3. Improved ergonomics: The matching of the wire clamp and the conductor is improved, and the ergonomic design of the manual operating lever and trigger assembly makes it easier for operators to complete the operation and reduces fatigue and discomfort caused by improper use of tools.

[0032] 4. Standardization of operating procedures: The operating method clarifies the steps, standardizes the operating process, reduces the safety hazards caused by improper operation, and makes the operation more operational and standardized.

[0033] 5. Reduce the risk of power outages: Since the new design allows safe live operations without power outages, it reduces the impact of power outages on important loads such as substations and ensures the stable operation of the power system.

[0034] 6. Improve tool convenience: The gun-shaped structure of the wire clamp operating device and the design that combines manual and insulating operations greatly improve the convenience of using the tool, allowing operators to operate more flexibly.

[0035] 7. Convenience of maintenance and troubleshooting: The design makes the removal and installation process of the wire clamp easier, allowing operators to perform maintenance and troubleshooting more quickly, reducing downtime.

[0036] In summary, the live access trench wire clamp for 0.4kV and below line conductors not only has a significant effect in improving safety, but also performs well in improving work efficiency, improving tool usage experience and reducing power outage risks, and can better meet the needs of modern power construction and maintenance.

DETAILED DESCRIPTION

[0042] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0043] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features and technical solutions in the embodiments can be combined with each other without conflict. It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0044] In order to effectively carry out line maintenance, troubleshooting and new installation and access, this embodiment proposes a live access trench wire clamp for 0.4kV and below line conductors, which is used to improve the operation method and the use of tools, improve the operation efficiency and reduce the personal safety risks of operators.

[0045] like Figure 1 As shown, the wire clamp for live access of line conductors of 0.4kV and below comprises a wire clamp body and a wire clamp operating device; wherein, the wire clamp body comprises three models, the S-1 model is suitable for use with 16 to 50 square wires, the S-2 model is suitable for use with 70 to 120 square wires, and the S-3 model is suitable for use with 150 to 240 square wires, so as to meet the live access of line conductors of 0.4kV and below.

[0046] The wire clamp body in this embodiment is a double groove wire clamp. Figure 1 and Figure 2As shown, the cross-section of the wire clamp body is I-shaped, and the wire clamp groove on one side of the wire clamp body can clamp the live wire, and the wire clamp groove on the other side can clamp the newly installed wire; the wire is clamped by the clamp block driven by the screw.

[0047] Specifically, clamping blocks capable of moving and clamping the wires are provided in the grooves of the wire clamps on both sides, and screws are provided above and below the wire clamp body, the screws extend into the wire clamp grooves and are rotatably connected to the clamping blocks, and the screws are threadedly connected to the wire clamp body. When in use, the screws are rotated to increase the length of the screws extending into the wire clamp grooves, thereby driving the clamping blocks to move and clamping the live wires or newly installed wires.

[0048] It should be noted that since the newly installed wire is not energized, in order for the wire clamp operating device to cooperate with the wire clamp body to clamp the energized wire, the screw should be selected to install the newly installed wire on the side above the wire clamp groove, and the operator can perform the clamping process of the newly installed wire with his bare hands at close range.

[0049] The wire clamp body is designed in an I-shape, which can clamp the newly installed wire without touching the live wire. The wire clamp body can meet the maximum current of the current area load. After the newly installed wire is clamped, the wire clamp operating device is used to complete the access to the live wire with an electric tool at an effective safety distance. After access, the wire clamp operating device is separated from the wire clamp body, and the wire clamp body is stable for use.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, the wire clamp operating device in this embodiment is a gun-shaped structure with a manual operating rod assembly and an insulating operating rod assembly. Considering the convenience of its assembly and disassembly with the wire clamp body, as shown in FIG. Figure 1 and Figure 2 As shown, in this embodiment, a connecting seat that cooperates with a wire clamp operating device is also provided below the wire clamp body; the wire clamp operating device is detachably connected to the connecting seat below the wire clamp body through a manual operating rod assembly, and is connected to the screw rod through an insulating operating rod assembly, and the screw rod is operated by an electric wrench of the insulating operating rod assembly, so that the screw rod drives the clamp block to quickly clamp the live wire.

[0051] In order to facilitate the understanding of the specific structure and function of the wire clamp operating device, the following detailed description is given:

[0052] like Figure 1 and Figure 2 As shown, the manual operating rod assembly and the insulating operating rod assembly of the wire clamp operating device in this embodiment are arranged in parallel. The manual operating rod assembly includes an operating rod, and the insulating operating rod assembly includes an insulating operating rod. Both the operating rod and the insulating operating rod are relatively long rod structures, which can effectively ensure the safe distance of the operation and avoid the risk of personal safety caused by large overlapping arcs and insufficient safety distance.

[0053] like Figure 2 and Figure 3 As shown, the operating rod of the manual operating rod assembly in this embodiment is hollow inside and is provided with a guide rod, the upper end of the guide rod is connected to a connector that matches the connection seat at the top of the operating rod, and the lower end of the guide rod extends to the outside of the operating rod and is connected to a trigger assembly. The connecting head allows the wire clamp operating device to be quickly connected or separated from the wire clamp body, wherein the separation action is quickly achieved by the trigger assembly.

[0054] Specifically, Figure 2 As shown, the connector is plugged and installed on the top of the operating rod, and a locking rod is provided in the connector. One end of the locking rod extends into the operating rod and is connected to the upper end of the guide rod, and the other end extends into the connecting seat below the wire clamp body and is provided with a locking groove. A limit rod and a limit lock ball matching the locking rod are provided in the connecting seat below the wire clamp body. The locking groove at the top of the locking rod and the limit lock ball in the connecting seat are not shown in the figure. Considering the stability of the connection between the wire clamp operating device and the wire clamp body, a connection state maintaining spring sleeved on the locking rod is also provided in the connector.

[0055] like Figure 3 As shown, the trigger assembly includes a trigger mounting seat, which is fixedly mounted on the insulating operating rod of the insulating operating rod assembly and is fixedly mounted on the lower end of the operating rod. A trigger and a linkage rod are rotatably mounted in the trigger mounting seat, and the trigger is connected to the lower end of the guide rod through the linkage rod; when the trigger is pulled, the guide rod is driven to move through the linkage rod.

[0056] When the trigger is pulled, the trigger drives the guide rod to move upward through the linkage rod, and the guide rod moves upward while driving the lock rod in the connector to move upward. At the same time, the connection state maintaining spring sleeved on the lock rod is compressed, and the limit lock ball in the connection seat moves toward the limit rod side, breaking away from the contact with the lock groove on the lock rod to unlock. At this time, the lock rod can be pulled out of the connection seat, so that the wire clamp operating device is separated from the wire clamp body. When the lock rod is inserted into the connection seat, the limit lock ball contacts the lock groove on the lock rod again to restore the locking state; at the same time, under the action of the connection state maintaining spring, the guide rod, linkage rod, and trigger return to the initial position; thereby, the wire clamp operating device can be quickly connected or separated from the wire clamp body.

[0057] like Figure 2 and Figure 3 As shown, the insulating operating rod of the insulating operating rod assembly in this embodiment is hollow inside and is provided with a driving rod, which is not shown in the figure; a hexagonal socket is rotatably installed on the top of the insulating operating rod, and an electric wrench is installed on the lower end; the lower end of the driving rod is connected to the output end of the electric wrench inside the insulating operating rod, and the upper end of the driving rod is fixedly connected to the hexagonal socket inside the insulating operating rod.

[0058] When the manual operating rod assembly is connected to the connecting seat below the wire clamp body, since the manual operating rod assembly and the insulating operating rod assembly of the wire clamp operating device are arranged in parallel, the hexagonal sleeve of the insulating operating rod assembly is sleeved on the screw rod below the wire clamp body; the electric wrench is started by pressing the starting button of the electric wrench, and the output end of the electric wrench drives the hexagonal sleeve to rotate quickly forward or reverse at the top end of the insulating operating rod through the driving rod, thereby realizing the rapid clamping of the live wire at a long distance through the electric tool.

[0059] Based on the above-mentioned live access trenching wire clamp for 0.4 kV and below line conductors, this embodiment also provides an operation method for maintenance, troubleshooting and new installation of access conductors, which operation method includes the following steps:

[0060] Step 1: clamp the newly installed wire through the wire clamp groove on one side of the wire clamp body; since the newly installed wire is not connected to electricity, this process does not require the use of a wire clamp operating device. After the newly installed wire enters the wire clamp groove, the screw on the top of the wire clamp body drives the clamp block to clamp it;

[0061] Step 2, using the wire clamp operating device, connect the manual operating rod assembly of the wire clamp operating device to the connecting seat below the wire clamp body, and at the same time connect the insulating operating rod assembly to the screw rod below the wire clamp body;

[0062] Step 3, using the wire clamp operating device to move the wire clamp body so that the live wire enters the wire clamp groove on the other side of the wire clamp body;

[0063] Step 4, start the electric wrench of the insulating operating rod assembly of the wire clamp operating device, and use the electric wrench to drive the screw under the wire clamp body to rotate, so that the screw under the clamp body drives the clamp block to complete the clamping of the live wire;

[0064] Step 5, operate the trigger of the manual operating rod assembly of the wire clamp operating device. The trigger drives the locking rod in the connector to move through the linkage rod and the guide rod, so that the connector and the connecting seat under the wire clamp body are unlocked. The wire clamp operating device can be separated from the wire clamp body to complete maintenance, troubleshooting and new installation of wire access operations.

[0065] In summary, the live access trenching wire clamp for 0.4kV and below line conductors reduces the actual contact between operators and live conductors by adopting an insulating operating rod assembly and an electric wrench, significantly reducing the risk of electric shock, and avoiding personal injuries such as burns and scalds caused by electric arcs. The use of double-groove wire clamps and clamping mechanisms reduces manual operation time, especially when facing live conductors, operators can complete clamping more quickly, improving the overall efficiency of the operation. The matching of the wire clamp and the conductor is improved, and the ergonomic manual operating rod and trigger assembly are designed, so that operators can complete the operation more easily, reducing fatigue and discomfort caused by improper use of tools. The operation process is standardized, the safety hazards caused by improper operation are reduced, and the operation is more operable and standardized. Live operations can be carried out safely without power outages, reducing the impact of power outages on important loads such as substations, and ensuring the stable operation of the power system. The gun-shaped structure of the wire clamp operating device and the design of combining manual and insulating operations greatly improve the convenience of the tool in use, and the operator can operate more flexibly. This makes the removal and installation process of the wire clamp easier, allowing operators to perform maintenance and troubleshooting more quickly, reducing downtime.

[0066] At the same time, it should be pointed out that the above description is only a typical embodiment of the present invention and does not limit the present invention in any form. Any changes made to the above embodiments based on the ideas and technical essence of the present invention are within the protection scope of the present invention.
