Abstract
Description
Technical Field
[0001] This application relates to the field of power equipment technology, and more particularly to a current-draining strip device. Background Technology
[0002] In the maintenance and construction of power transmission lines, tension clamp current-carrying bars are key components, and their performance directly affects the safety and reliability of the transmission lines. Traditional current-carrying bars often employ a pre-twisted design, where pre-twisted wires are wound around the conductor in a spiral structure to increase the contact area and friction, thereby improving current transmission efficiency. However, this design has some inherent limitations. For example, due to the high rigidity of the pre-twisted wires, they may not perfectly conform to the curvature of the conductor, leading to poor contact and reduced current transmission efficiency. Furthermore, the adhesive material between the pre-twisted wires may age over long-term operation, affecting its conductivity and mechanical strength.
[0003] Existing current-carrying strips are typically used as part of tension safety backup clamps or independently. They are mostly made of aluminum alloy, with single aluminum alloy wires bent into spiral pre-twisted wires using specialized equipment. Multiple pre-twisted wires are then glued together, and conductive sand is laid on the inside to increase conductivity. While this design meets the requirements of transmission lines to some extent, it has also revealed some problems in practical applications. For example, due to the rigid connection of the current-carrying strip, the conductor and jumper wire are prone to pulling on each other during vibration and swaying, easily leading to friction and wear at the contact transition section, potentially causing fatigue failure under long-term operation. Furthermore, the current-carrying strip is relatively long and heavy, which not only increases the difficulty of installation but also raises production costs.
[0004] In summary, existing drainage strip products suffer from insufficient overall performance and high maintenance costs. Utility Model Content
[0005] In view of this, the purpose of this application is to provide a current diversion strip device to improve the overall performance of transmission lines and reduce maintenance costs.
[0006] To achieve the above-mentioned technical objectives, this application provides a drainage strip device, including a drainage line and two wire clamps;
[0007] The wire clamp is provided with a clamping cavity;
[0008] One of the wire clamps has a clamping cavity through which a wire passes and is clamped;
[0009] The clamping cavity of the other clamp allows the jumper cable to pass through and clamps the jumper cable;
[0010] The drain wire is an aluminum stranded wire;
[0011] The drain line is connected between the two clamps and is pre-bent.
[0012] Furthermore, the drainage line is pre-bent into an S-shape.
[0013] Furthermore, the inner wall surface of the clamping cavity is provided with an anti-slip structure.
[0014] Furthermore, the anti-slip structure is a threaded structure.
[0015] Furthermore, the wire clamp is a hinged wire clamp structure.
[0016] Furthermore, the wire clamp includes a fixed clamping piece, a movable clamping piece, and a locking assembly;
[0017] One end of the movable clip is connected to one end of the fixed clip via a hinge.
[0018] The other end of the movable clip is detachably pressed against the fixed clip by the locking assembly;
[0019] One side of the movable clip is provided with a first groove;
[0020] One side of the fixing clip is provided with a second groove;
[0021] When the movable clamping piece is pressed against the fixed clamping piece, the first groove and the second groove form the clamping cavity;
[0022] The other end of the fixing clip is provided with a connector for connecting the drain line.
[0023] Furthermore, the connector is a press-fit pipe.
[0024] Furthermore, the locking assembly includes a bolt and a rivet nut;
[0025] Both the fixed clamp and the movable clamp are provided with through holes;
[0026] The sealing nut is riveted and fixed to one of the through holes;
[0027] The bolt passes through another of the through holes and is threaded into the rivet nut.
[0028] Furthermore, the locking assembly also includes a rubber ring;
[0029] The rubber ring is fitted onto the bolt.
[0030] Furthermore, there are at least two locking components, which are spaced apart.
[0031] As can be seen from the above technical solutions, the drainage strip device designed in this application has the following beneficial effects:
[0032] 1. By using a clamp and a drain wire to create a new current-carrying channel at the tension clamp, the total current-carrying area from the conductor to the jumper is increased, the overall resistivity is reduced, and the heat generation problem at the tension drain wire clamp is alleviated.
[0033] 2. It has a simple structure, light weight and small size, and short installation length. It also uses a clamping method to fix the wires / jump wires, which is easy to install and has good electrical contact performance.
[0034] 3. Aluminum stranded wire is used as the drain wire, and it is pre-bent to form a telescopic structure, which effectively absorbs conductor vibration and improves the problem of traditional drain strips pulling and jumping wires when the conductor vibrates.

Simultaneously, it possesses excellent electrical contact performance, a stable and reliable structure, is easy to install, and is not easily separated, thus achieving the goal of improving the overall performance of the transmission line and reducing maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0044] This application discloses a drainage strip device.
[0045] Please see Figure 1 One embodiment of the drainage strip device provided in this application includes:
[0046] The device includes a drain wire 2 and two clamps 1; each clamp 1 has a clamping cavity; one clamp 1 has a clamping cavity through which a wire 4 passes and clamps the wire 4, and the other clamp 1 has a clamping cavity through which a jumper wire 3 passes and clamps the jumper wire 3.
[0047] The lead wire 2 is an aluminum stranded wire, preferably a small-pitch soft aluminum stranded wire. The small strand pitch makes the cable flexible and easy to bend, and the structure is stable and not easy to loosen when bent.
[0048] The drain line 2 is connected between the two clamps 1 and is pre-bent. During installation, the drain line 2 is pre-bent so that when the conductor 4 vibrates, the pre-bent structure of the drain line 2 can expand and contract with the conductor 4, effectively reducing the pulling effect of the conductor 4 on the tension down conductor.
[0049] As can be seen from the above technical solutions, the drainage strip device designed in this application has the following beneficial effects:
[0050] 1. By using clamp 1 and drain wire 2 to create a new current-carrying channel at tension clamp 1, the total current-carrying area from conductor 4 to jumper 3 can be effectively increased. This significantly reduces the overall resistivity, thereby alleviating the overheating problem at clamp 1 of the tension drain wire 2. This method not only improves the current-carrying capacity of conductor 4 but also effectively solves the overheating problem of conductor 4, improving the stability and safety of the transmission line.
[0051] 2. The drainage strip device designed in this application has a simple structure, is lightweight and compact, and has a short installation length, making it more convenient and faster during construction. Furthermore, the device uses a clamping method to fix the wire 4 / jump wire 3, a design that not only facilitates construction but also provides excellent electrical contact performance. This structural design allows the drainage strip device to significantly improve construction efficiency and reduce construction difficulty while ensuring performance.
[0052] 3. The diversion line 2 uses aluminum stranded wire and is pre-bent to form a telescopic structure. This design can effectively absorb the vibration of the conductor 4, improving the problem of the traditional diversion bar pulling the jumper 3 after the conductor 4 vibrates. This telescopic structure design allows the diversion bar device to better adapt to and absorb vibration when facing the vibration of the conductor 4, thereby protecting the jumper 3 from damage and improving the stability and safety of the transmission line.
[0053] In summary, the drain strip device designed in this application aims to improve the flexibility and fit of the drain strip, ensuring a perfect fit with the curvature of the jumper wire 3, thereby reducing friction between the drain strip and the conductor 4 and the jumper wire 3. Simultaneously, the device possesses excellent electrical contact performance, a stable and reliable structure, is easy to install, and is not easily separated, thus achieving the goal of improving the overall performance of the transmission line and reducing maintenance costs. This design not only improves the stability and safety of the transmission line but also significantly reduces maintenance costs, demonstrating high practical value and economic benefits.
[0054] The above is Embodiment 1 of the drainage strip device provided in this application. The following is Embodiment 2 of the drainage strip device provided in this application. Please refer to the following for details. Figures 1 to 3 .
[0055] Based on the above embodiments:
[0056] Furthermore, such as Figure 1 As shown, the drainage line 2 can be pre-bent into an S-shape.
[0057] This S-shaped pre-bending design further enhances its ability to absorb vibrations from the conductor 4. When the conductor 4 vibrates due to external forces such as wind, the S-shaped drain wire 2 can better conform to the vibration direction of the conductor 4, absorbing and mitigating this vibration through its own expansion and contraction deformation, thus more effectively protecting the jumper wire 3 from damage. In addition, the S-shaped pre-bending setting also helps to improve the structural stability of the drain wire 2, making it less prone to loosening during use, further extending the service life of the drain strip device.
[0058] Furthermore, the inner wall of the clamping cavity is provided with an anti-slip structure. This anti-slip structure is designed to increase the friction between the clamping cavity and the wire 4 or jumper 3, preventing the wire 4 or jumper 3 from sliding or falling out within the clamping cavity. In practical applications, the wire 4 or jumper 3 may experience slight movement due to factors such as wind or temperature changes. If the inner wall of the clamping cavity is smooth, the wire 4 or jumper 3 may loosen, thus affecting the performance of the drainage strip device. By setting the anti-slip structure, the clamping cavity's fixation effect on the wire 4 or jumper 3 can be effectively improved, ensuring the stability and reliability of the drainage strip device.
[0059] Furthermore, the anti-slip structure is a threaded structure. The threaded structure design is not only simple and effective but also easy to manufacture. When the conductor 4 or jumper 3 is clamped in the clamping cavity with the threaded structure, the threaded structure can form multi-point contact with the surface of the conductor 4 or jumper 3, thereby greatly increasing friction and preventing slippage or detachment. In addition, the threaded structure can also generate a certain radial compressive force on the conductor 4 or jumper 3, further enhancing its fixing effect. This anti-slip design of the threaded structure allows the diversion strip device to maintain stable performance in various complex environments, ensuring the safe operation of the transmission line.
[0060] Furthermore, such as Figure 2 as well as Figure 3 As shown, the wire clamp 1 is a hinged wire clamp structure. This hinged wire clamp design allows the wire clamp 1 to open and close flexibly, facilitating the installation and removal of the conductor 4 or jumper wire 3. In actual operation, construction personnel can easily clamp the conductor 4 or jumper wire 3 within the wire clamp 1 and secure it using the locking assembly, greatly improving construction efficiency. Simultaneously, the hinged wire clamp structure allows the wire clamp 1 to adapt to minor deformations of the conductor 4 or jumper wire 3 during use, maintaining a stable clamping effect. This design not only improves the adaptability and durability of the drainage strip device but also helps reduce construction difficulty and maintenance costs.
[0061] Furthermore, such as Figure 2 as well as Figure 3As shown, taking the hinged wire clamp design as an example, the wire clamp 1 may specifically include a fixed clamping piece 12, a movable clamping piece 11, and a locking assembly; one end of the movable clamping piece 11 is connected to one end of the fixed clamping piece 12 via a hinge 13 (such as a hinge); the other end of the movable clamping piece 11 is detachably pressed against the fixed clamping piece 12 via the locking assembly; one side of the movable clamping piece 11 is provided with a first groove; one side of the fixed clamping piece 12 is provided with a second groove; when the movable clamping piece 11 is pressed against the fixed clamping piece 12, the first groove and the second groove form the clamping cavity; the other end of the fixed clamping piece 12 is provided with a connector 15 for connecting the drain wire 2.
[0062] Furthermore, such as Figure 2 as well as Figure 3 As shown, the connector 15 is a crimping tube. The crimping tube design ensures that the lead wire 2 is securely connected to the clamp 1, preventing it from easily falling off. In practical applications, the lead wire 2 needs to withstand significant current and mechanical stress. If the connection is not secure, the lead wire 2 may loosen or break, affecting the normal operation of the transmission line. The crimping tube, through its unique structure and material, effectively clamps and fixes the lead wire 2 to the clamp 1, ensuring the stability and reliability of the lead wire 2. Simultaneously, the crimping tube also has excellent conductivity, ensuring smooth current transmission in the lead wire 2, further improving the efficiency and safety of the transmission line.
[0063] Furthermore, such as Figure 2 as well as Figure 3 As shown, the locking assembly includes a bolt 142 and a rivet nut 141; both the fixed clamping plate 12 and the movable clamping plate 11 are provided with through holes; the rivet nut 141 is riveted and fixed to one of the through holes; the bolt 142 passes through the other through hole and is threadedly connected to the rivet nut 141.
[0064] The combination of bolt 142 and rivet nut 141 ensures that the locking assembly firmly presses the movable clamp 11 onto the fixed clamp 12, thereby guaranteeing stable clamping of the wire 4 or jumper 3 within the clamping cavity. In practical applications, this locking method is not only simple and reliable but also easy to operate and maintain. Construction workers can open, close, and lock the wire clamp 1 simply by rotating bolt 142, greatly improving work efficiency. Simultaneously, the design of rivet nut 141 prevents bolt 142 from loosening or falling off during use, further enhancing the stability and reliability of the locking assembly.
[0065] Furthermore, such as Figure 3As shown, the locking assembly also includes a rubber ring 143 (O-ring 143), which is fitted onto the bolt 142. The rubber ring 143 is designed primarily to increase the sealing and friction between the bolt 142 and the through hole, preventing the bolt 142 from loosening due to vibration or external forces during use, and preventing it from falling off during installation. Simultaneously, the rubber ring 143 also possesses a certain degree of elasticity, which can absorb and mitigate minor displacements caused by vibration in the conductor 4 or jumper 3, thereby further protecting the stability and reliability of the diversion strip device. This design of the rubber ring 143 ensures that the diversion strip device maintains stable performance under various complex environments and external forces, guaranteeing the safe operation of the transmission line.
[0066] Furthermore, such as Figure 2 As shown, there are at least two locking components, which are spaced apart.
[0067] This multi-locking component design with its intervals is intended to increase the width of the clamp 1, thereby improving its clamping force and stability on the conductor 4 or jumper 3. This effectively prevents displacement or loosening due to external forces, while also reducing the potential for overheating in the clamp 1. This design not only enhances the adaptability and durability of the current-draining strip device but also helps ensure the stability and safety of the transmission line.
[0068] In general, this application relates to a design in which two clamps 1 are respectively fixed to a conductor 4 and a jumper 3, and connected by a drain wire 2. These clamps 1 employ a hinged structure, which, compared to a pre-twisted type, significantly reduces the installation length without affecting the curvature of the jumper 3. The hinged clamp design facilitates operation and simplifies the installation process. Furthermore, a locking assembly consisting of a rivet nut 141, a bolt 142, and a rubber ring 143 prevents the bolt 142 from accidentally falling off during installation. The lower end of the clamp 1 uses a crimped tube structure as a connector 15, which is tightly crimped to the drain wire 2, thereby effectively increasing the contact current-carrying area and reducing contact resistance.
[0069] Between these clamps 1, a soft aluminum stranded wire with a small pitch is used as the guide wire 2. This type of stranded wire is characterized by its small pitch, making it flexible and easy to bend, maintaining structural stability even when bent and preventing loosening. During installation, the guide wire 2 is pre-bent into an S-shape. When the conductor 4 vibrates, this pre-bent structure of the guide wire 2 can expand and contract with the vibration of the conductor 4, effectively reducing the pulling effect of the conductor 4 on the tension down conductor.
[0070] The above provides a detailed description of the drainage strip device provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
