Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, according to an embodiment of the present invention, a fixing device for preventing lead wire swaying during live working is provided, comprising: a connector 110; a fixing base 120 disposed on the connector 110; an opening and closing mechanism 130 disposed on the fixing base 120; and a driving mechanism 140 disposed on the fixing base 120. The driving mechanism 140 is drivenly connected to the opening and closing mechanism 130, such that the driving mechanism 140 can drive the opening and closing mechanism 130 to open to place the lead wire, or drive the opening and closing mechanism 130 to close to form an arc-shaped clamping surface to fix lead wires of different diameters.

[0023] The fixing device for preventing lead wire swaying during live working provided in this embodiment of the invention mainly consists of a connector 110, a fixing base 120, an opening and closing mechanism 130, and a driving mechanism 140.

[0024] The connector 110 can be securely connected to various operating rods, supports and other equipment used in live-line work, ensuring reliable installation of the entire fixed device in live-line work scenarios.

[0025] The fixed base 120 is mounted on the connector 110 and serves as the mounting carrier for the opening and closing mechanism 130 and the drive mechanism 140. It has sufficient structural strength and stability to ensure that the mechanisms will not shake or shift during operation, thus guaranteeing the overall structural stability of the device.

[0026] The mounting base 120 has a block-shaped structure.

[0027] The block structure has a large volume and mass, which can provide a stable installation foundation for the connector 110, the opening and closing mechanism 130 and the drive mechanism 140, reduce the shaking and displacement of the device caused by external force or lead wire tension during live operation, and improve the overall structural reliability of the device.

[0028] In addition, the block structure has a flat surface and sufficient installation space, which can flexibly adapt to the installation requirements of connectors 110, opening and closing mechanisms 130 and drive mechanisms 140 of different sizes, making it easy to integrate and assemble the components and reducing assembly difficulty and errors.

[0029] The opening and closing mechanism 130 is mounted on the fixed base 120, which can clamp and release the drainage line. The mechanism includes an arc-shaped clamping surface, which can fit well with the cylindrical surface of the drainage line, increase the contact area, and improve the stability of clamping.

[0030] The drive mechanism 140 is also mounted on the fixed base 120 and is connected to the opening and closing mechanism 130, serving as the power source for the entire device's operation.

[0031] This device drives the opening and closing mechanism 130 through the drive mechanism 140 to adjust the opening and closing range. With the curvature adaptation characteristics of the arc-shaped clamping surface, it can adapt to a variety of different diameter drain wires without replacing special clamping parts, which greatly improves the versatility and adaptability of the device and effectively reduces the frequency of equipment replacement and work preparation costs in live-line work.

[0032] The arc-shaped clamping surface formed by the closure of the opening and closing mechanism 130 can closely fit the outer contour of the drain wires of different diameters. By replacing point / line contact with surface contact, it can not only disperse clamping stress and avoid damage to the drain wires caused by uneven clamping force, but also ensure the clamping tightness of drain wires of different sizes. Structurally, it eliminates the problem of swinging or loosening of the drain wires after clamping, effectively ensuring the safety of equipment and personnel during live-line work.

[0033] The precise drive control of the drive mechanism 140 on the opening and closing mechanism 130, combined with the adaptive fitting of the arc-shaped clamping surface to multiple sizes of drain wires, enables this device to fix multiple specifications of drain wires while simplifying the operation steps of operators, improving the overall efficiency of live-line work, and adapting to the complex working conditions on site.

[0034] The drive mechanism 140 has multiple implementations, as detailed below.

[0035] The bidirectional snap-fit ​​structure possesses elastic deformation capability. When placing the drain cable, the snaps can elastically open under external force, facilitating the smooth insertion of the drain cable. Once the drain cable is in place, the snaps clamp the drain cable using their own elastic restoring force, effectively securing the drain cable and preventing it from swinging during live-line work. The bidirectional snap-fit ​​structure, with its elastic deformation, can accommodate drain cables of different diameters, and the clamping force is uniform, effectively preventing the drain cable from swinging or shifting during operation. The elastic design of the bidirectional snap-fit ​​and the adjustable stroke of the gear and rack drive allow this fixing device to adapt to drain cables of different diameters, eliminating the need for dedicated fixing devices for different specifications of drain cables. This significantly improves the versatility and applicability of the device, reducing preparation time and costs.

[0036] The rack and pinion drive mechanism, when the drive gear rotates, drives the rack in linear motion, which in turn drives the clamping jaws to open and close. After the clamping jaws are adjusted to the appropriate position to clamp the drain cable, the position of the rack is fixed by the locking bolt, thereby limiting the retraction of the clamping jaws and ensuring continuous and stable clamping of the drain cable. The design of the rack and pinion drive combined with the locking bolt not only enables precise opening and closing of the clamping jaws, but also reliably locks the position after clamping the drain cable, preventing loosening due to vibration or external force, and ensuring that the drain cable remains stable during live-line operations.

[0037] The eccentric wheel clamping mechanism features an eccentric wheel structure with an arc-shaped clamping surface. When the eccentric wheel rotates, its arc-shaped clamping surface gradually approaches and presses against the drainage line. With the continuous rotation of the eccentric wheel, utilizing its eccentric self-locking characteristic, the eccentric wheel will not loosen on its own even under external force disturbance, thus achieving reliable clamping of the drainage line and effectively preventing the drainage line from loosening and swaying.

[0038] The eccentric wheel structure utilizes the eccentric self-locking characteristic to provide excellent anti-loosening capability after clamping the guide line. Even in complex outdoor working environments, it can maintain stable clamping of the guide line in the face of external forces such as wind, further improving the reliability of the fixation.

[0039] The stable fixing effect can effectively avoid safety risks such as short circuits and discharges caused by the swing of the drain wire, greatly improve the safety of live work, and ensure the safety of workers and equipment.

[0040] Each drive mechanism 140 is easy and efficient to operate. The elastic opening and closing of the two-way buckle, the smooth transmission of the gear rack, and the rapid rotation of the eccentric wheel all enable the operator to complete the fixing and releasing of the drain line in a short time, which significantly improves the efficiency of live-line work and reduces the labor intensity of the operator.

[0041] The opening and closing mechanism 130 of the present invention includes: a first side plate 131, having a first concave arc-shaped notch 1311, with a first connecting portion 1312 and a second connecting portion 1313 respectively on opposite sides of the first concave arc-shaped notch 1311, the first connecting portion 1312 being connected to the fixed base 120; a movable plate 132, having a second concave arc-shaped notch 1321, the movable plate 132 being rotatably connected to the second connecting portion 1313, such that the second concave arc-shaped notch 1321 and the first concave arc-shaped notch 1311 form a hole for clamping the drainage line when the opening and closing mechanism 130 is in the closed state; wherein, the driving mechanism 140 is movably connected to the movable plate 132.

[0042] In this embodiment, the opening and closing mechanism 130 of the present invention is mainly composed of a first side plate 131 and a movable plate 132, which are connected by a hinge to realize flexible opening and closing action.

[0043] The mechanism is installed on the fixed base 120 and is powered by the drive mechanism 140, together forming a functional module for clamping and fixing the drain line.

[0044] The first side plate 131 is a semi-circular plate structure with a first concave arc-shaped notch 1311 on its inner side. The curvature of this arc-shaped notch is designed to match the outer contour of a common high-voltage drain line. At both ends of the first concave arc-shaped notch 1311, there are a first connecting part 1312 and a second connecting part 1313, respectively. The first connecting part 1312 is threadedly connected to the mounting hole on the fixed base 120. The second connecting part 1313 is hinged to one end of the movable plate 132 via a rotating shaft, forming the core fulcrum for the opening and closing action.

[0045] The movable plate 132 has an arc-shaped plate structure, with a second concave arc-shaped notch 1321 on its inner side that matches the arc of the first concave arc-shaped notch 1311. The center diameter of the movable plate 132 is 12.50 mm, the arc-shaped outer contour dimension is R8.6 mm, and the tooth angle of the first ratchet is 60°. One end of the movable plate 132 is rotatably connected to the second connecting part 1313 of the first side plate 131, and the other end is movably connected to the output end of the drive mechanism 140. This design allows the linear motion of the drive mechanism 140 to be converted into the rotational motion of the movable plate 132, thereby realizing the opening and closing action.

[0046] When the drain wire needs to be placed, the drive mechanism 140 actuates, pulling the movable plate 132 outward around the second connecting part 1313. This separates the two concave arc-shaped notches, forming an open receiving space, allowing the operator to easily place the drain wire into the first concave arc-shaped notch 1311. After the drain wire is in place, the drive mechanism 140 resets, pushing the movable plate 132 to rotate towards the first side plate 131. This continues until the second concave arc-shaped notch 1321 and the first concave arc-shaped notch 1311 are completely closed, forming a complete circular clamping hole. At this point, the inner surface of the circular clamping hole is tightly fitted to the surface of the drain wire, generating sufficient clamping force to effectively prevent the drain wire from swinging or loosening during live-line work.

[0047] Because the rotation angle of the movable plate 132 can be adaptively adjusted according to the diameter of the drainage line, the opening and closing mechanism 130 can be adapted to various drainage lines of different diameters without replacing any parts. This feature significantly improves the versatility of the device, reduces the frequency of tool changes during on-site operations, and thus improves overall work efficiency.

[0048] The movable plate 132 is provided with a pin 134, and the first side plate 131 and the second side plate 133 are respectively provided with a second connecting part 1313. The second connecting part 1313 is a round hole and is connected to the pin 134.

[0049] At the rotation axis of the movable plate 132, there is a pin 134 that runs through its thickness direction. The pin 134 is integrally formed with the movable plate 132 or fixed by interference fit.

[0050] At corresponding positions of the first side plate 131 and the second side plate 133, there are circular holes serving as second connecting parts 1313, and the inner diameter of the circular holes is in a precision clearance fit with the outer diameter of the pin 134.

[0051] The pins 134 of the movable plate 132 are inserted into the round holes of the first side plate 131 and the second side plate 133 respectively, forming a rotating pair of the movable plate 132.

[0052] This design allows the movable plate 132 to rotate smoothly in an arc within the arc-shaped track 1301 defined by the first side plate 131 and the second side plate 133, with the pin 134 as the center, thus realizing the opening and closing action.

[0053] The precise fit between the pin 134 and the round holes on both side plates ensures that the movable plate 132 remains coaxial with the first side plate 131 and the second side plate 133 during rotation. This ensures that the second concave arc notch 1321 of the movable plate 132 and the first concave arc notch 1311 of the first side plate 131 can be precisely aligned, thus avoiding damage or loosening of the drainage line caused by eccentric clamping.

[0054] The hinge point is supported by the round holes on both sides, which evenly distributes the clamping reaction force borne by the movable plate 132 to the two side plates, avoiding stress concentration caused by unilateral force, significantly improving the load-bearing capacity and fatigue resistance of the hinge structure, and extending the service life of the device.

[0055] The clearance fit between the pin 134 and the round hole, combined with the guidance of the arc-shaped track 1301, makes the rotation of the movable plate 132 smoother, effectively reducing the driving force required by the drive mechanism 140 and making the operation of the operator more labor-saving.

[0056] This double-supported hinge structure effectively restricts the radial movement of the movable plate 132, prevents the movable plate 132 from tilting or falling off, ensures the stability of the ratchet engagement, and improves the reliability and safety of the entire opening and closing mechanism 130.

[0057] The first connecting part 1312 is a plate-shaped structure integrally formed with the first side plate 131. This integrally formed plate-shaped structure eliminates stress concentration points caused by splicing or welding, and can withstand the large forces generated by the opening and closing mechanism 130 when clamping and releasing the drain line. This effectively avoids breakage or deformation of the connecting part, improving the durability and reliability of the entire opening and closing mechanism 130. This design allows the clamping reaction force borne by the first side plate 131 to be directly and evenly transmitted to the fixed base 120 through the plate-shaped connecting part, avoiding force transmission losses caused by connection gaps or stiffness differences, and ensuring the clamping stability of the mechanism.

[0058] In one embodiment, the outer side of the movable plate 132 is provided with a first ratchet 1322, which is arranged circumferentially along the second concave arc-shaped notch 1321. The drive mechanism 140 includes an elastic member 141 and a handle 142. The elastic member 141 is provided with a second ratchet 1410, so that the second ratchet 1410 and the first ratchet 1322 can be engaged or disengaged under elastic action.

[0059] The drive mechanism 140 of the present invention adopts a design that combines ratchet engagement and elastic reset, and cooperates with the ratchet on the outer side of the movable plate 132 to achieve precise and self-locking control of the opening and closing mechanism 130.

[0060] On the outer side of the movable plate 132, a first ratchet 1322 is arranged circumferentially along the second concave arc-shaped notch 1321. The ratchet is in the shape of continuous saw teeth, and its tooth shape is adapted to the second ratchet 1410 of the drive mechanism 140, so as to transmit driving force and achieve self-locking.

[0061] The drive mechanism 140 is mainly composed of two parts: an elastic member 141 and a handle 142.

[0062] The elastic member 141 is provided with a second ratchet 1410. Under the action of elastic force, the second ratchet 1410 always maintains the tendency to mesh with the first ratchet 1322.

[0063] The handle 142 is linked to the elastic member 141. By moving the handle 142, the elastic force can be overcome, causing the second ratchet 1410 to disengage from the first ratchet 1322, thereby allowing the movable plate 132 to rotate freely.

[0064] In the closed clamping state, the elastic member 141, under the action of the return spring, pushes the second ratchet 1410 to tightly engage with the first ratchet 1322 on the movable plate 132. At this time, the one-way locking characteristic of the ratchet prevents the movable plate 132 from rotating outward, keeping the opening and closing mechanism 130 in the closed state and stably clamping the drain line.

[0065] When the release state is open, when it is necessary to release the drain line, the operator pulls the handle 142, which pulls the elastic component 141 through the lever principle, causing the second ratchet 1410 to move downward along the guide groove and disengage from the first ratchet 1322. At this time, the movable plate 132 can rotate freely outward to open the clamping hole and release the drain line.

[0066] During the closing process, as the movable plate 132 rotates adaptively with the diameter of the drainage line, the first ratchet 1322 pushes the second ratchet 1410 to overcome the elastic force and produce a slight retraction until a suitable engagement position is found. This process requires no additional operation and achieves adaptive clamping for drainage lines of different diameters.

[0067] The elastic member 141 also includes a return spring and a guide groove to ensure smooth movement of the ratchet during engagement and disengagement.

[0068] The unidirectional meshing characteristic of the ratchet ensures that the opening and closing mechanism 130 will not be accidentally opened due to the tension of the drain line or the action of external force after it is closed, realizing self-locking clamping, effectively preventing the drain line from coming loose during live work, and ensuring work safety.

[0069] The continuous meshing design of the ratchet allows the movable plate 132 to adaptively adjust the rotation angle according to the diameter of the drainage line, which can be adapted to various specifications of drainage lines without replacing any parts, significantly improving the versatility and operational efficiency of the device.

[0070] The ratchet can be disengaged and reset simply by turning the handle 142. The operation is simple, and the assistance of the elastic component 141 effectively reduces the operator's workload and improves on-site work efficiency.

[0071] The integrated design of ratchet engagement and elastic reset eliminates the need for complex transmission components, resulting in a compact overall structure and reduced potential failure points. Furthermore, the direct force transmission path of the ratchet engagement effectively avoids clamping loosening issues caused by transmission backlash, thus improving the reliability of the device.

[0072] Furthermore, the mounting base 120 is provided with a mounting cavity 1201, and the elastic member 141 includes: a support post 1411, disposed in the mounting cavity 1201, one end of the support post 1411 is provided with a second ratchet 1410, the support post 1411 can extend out of the mounting cavity 1201 so that the second ratchet 1410 engages with the first ratchet 1322; and an elastic element 1412, disposed in the mounting cavity 1201, the support post 1411 and the elastic element 1412 are connected. A handle 142 is disposed at the other end of the support post 1411, and the handle 142 extends out of the mounting cavity 1201 so that it can be pressed.

[0073] The elastic member 141 is integrated into the mounting cavity 1201, enabling a compact and reliable ratchet engagement and unlocking function.

[0074] The mounting cavity 1201 is the core housing space of the drive mechanism 140. It has a guide structure machined inside to constrain the linear movement of the support column 1411 and ensure that the second ratchet 1410 and the first ratchet 1322 on the movable plate 132 are precisely engaged.

[0075] The support column 1411 is a long strip rod, which is installed as a whole in the mounting cavity 1201. One end of it is provided with a second ratchet 1410, which can extend out of the mounting cavity 1201 under the action of elastic force and engage with the first ratchet 1322 on the outer side of the movable plate 132; the lower end is connected to the elastic element 1412 and extends out of the mounting cavity 1201 to be fixedly connected to the handle 142.

[0076] The elastic element 1412 is a compression spring, which can be installed at the bottom of the support column 1411 or sleeved on the lower part of the support column 1411 and installed at the bottom of the mounting cavity 1201. In its natural state, the spring pushes the support column 1411 upward, so that the second ratchet 1410 remains engaged with the first ratchet 1322.

[0077] When no external force is applied, the elastic force of the elastic element 1412 pushes the support column 1411 upward, causing the second ratchet 1410 to extend out of the mounting cavity 1201 and tightly engage with the first ratchet 1322 on the movable plate 132, thereby realizing the self-locking clamping of the opening and closing mechanism 130.

[0078] When the opening and closing mechanism 130 needs to be opened, the operator presses down the handle 142, which compresses the elastic element 1412 through the support column 1411, causing the second ratchet 1410 to move downward and retract into the mounting cavity 1201, disengaging from the first ratchet 1322. At this time, the movable plate 132 can rotate freely to release the drain line.

[0079] After the handle 142 is released, the elastic force of the elastic element 1412 pushes the support column 1411 and the handle 142 to reset, the second ratchet 1410 extends again and engages with the first ratchet 1322, and the opening and closing mechanism 130 is locked again.

[0080] The core component of the elastic member 141 is integrated into the mounting cavity 1201 inside the fixed base 120, which avoids the erosion of external pollutants such as dust and rainwater, reduces the impact of environmental factors on the reliability of the mechanism, and makes the overall structure more compact, easy to carry and operate.

[0081] The guide structure of the mounting cavity 1201 ensures that the support column 1411 always moves in a straight line, making the meshing position of the second ratchet 1410 and the first ratchet 1322 accurate, avoiding meshing failure or tooth surface wear caused by misalignment, and improving the service life and reliability of the mechanism.

[0082] The continuous thrust of the elastic element 1412 keeps the second ratchet 1410 and the first ratchet 1322 tightly engaged, while allowing the movable plate 132 to adaptively adjust the rotation angle according to the diameter of the drain line, so as to achieve stable clamping of drain lines of different specifications without replacing any parts, which significantly improves the versatility and work efficiency of the device.

[0083] Furthermore, the opening and closing mechanism 130 also includes a second side plate 133, which is respectively disposed on opposite sides of the fixed base 120 and forms a track 1301 with the fixed base 120 to guide the movable plate 132 to rotate and realize the opening and closing action.

[0084] The opening and closing mechanism 130 of the present invention adds a second side plate 133 on the basis of the first side plate 131. The two are arranged symmetrically and together constitute the rotation guide and constraint structure of the movable plate 132.

[0085] The second side plate 133 and the first side plate 131 are respectively installed on opposite sides of the fixed base 120. The two are connected by an arc-shaped connecting part at the top to form a "C"-shaped overall frame. This frame and the fixed base 120 together enclose an arc-shaped track 1301 space, providing precise guidance for the rotation of the movable plate 132.

[0086] The edge of the movable plate 132 can be embedded in the arc-shaped track 1301. When the drive mechanism 140 drives the movable plate 132 to rotate, the track 1301 will strictly constrain the movement trajectory of the movable plate 132, so that it can only move in an arc along the circumference of the second concave arc-shaped notch 1321, ensuring that the second concave arc-shaped notch 1321 of the movable plate 132 and the first concave arc-shaped notch 1311 of the first side plate 131 always remain coaxially aligned.

[0087] The inner side of the second side plate 133 is also arc-shaped. In the closed clamping state, it and the first side plate 131 together provide support for the movable plate 132 from both sides, enhancing the rigidity of the overall structure and effectively dispersing the radial load caused by the tension of the drainage line.

[0088] The arc-shaped track 1301 precisely guides the rotation of the movable plate 132, ensuring that the first ratchet 1322 on the movable plate 132 and the second ratchet 1410 of the drive mechanism 140 always maintain the correct meshing angle, avoiding ratchet disengagement or wear caused by the misalignment of the movable plate 132, and improving the reliability and service life of the mechanism.

[0089] The frame structure formed by the first and second side plates 133 significantly improves the overall rigidity of the opening and closing mechanism 130, enabling it to better withstand the swing tension and impact force generated by the drain line during live operation, effectively preventing mechanism deformation and ensuring clamping stability.

[0090] The constraint of track 1301 ensures that when the movable plate 132 is closed, its second concave arc-shaped notch 1321 is precisely aligned with the first concave arc-shaped notch 1311 of the first side plate 131, forming a clamping hole with a fixed center. This ensures that the drainage line is always in the center position, avoiding damage or loosening of the line due to eccentric clamping.

[0091] The closed frame structure formed by the two side plates provides good protection for the internal movable plate 132 and ratchet engagement area, effectively preventing debris and dust from entering during on-site operations and reducing the impact of environmental factors on the mechanism. It is particularly suitable for complex outdoor live-line working conditions.

[0092] Furthermore, the inner walls of the first concave arc-shaped notch 1311 and the second concave arc-shaped notch 1321 are provided with elastic anti-slip pads. The surface of the elastic anti-slip pads is provided with uniformly distributed anti-slip textures, and the material of the elastic anti-slip pads is high-voltage resistant insulating rubber.

[0093] An elastic anti-slip pad is fitted onto the inner walls of the first concave arc-shaped notch 1311 of the first side plate 131 and the second concave arc-shaped notch 1321 of the movable plate 132. The pad is integrally molded from high-voltage resistant insulating rubber material, and its surface is processed with uniformly distributed diamond or wavy anti-slip patterns.

[0094] The elastic anti-slip pad layer is firmly bonded to the inner wall of the metal notch through vulcanization or high-strength insulating adhesive. It has a uniform thickness and a moderate compression allowance, and can adaptively deform with the outer contour of the drainage line when clamped to achieve a tight wrap.

[0095] The high-voltage resistant insulating rubber padding layer forms a reliable electrical isolation barrier between the metal clamping mechanism and the lead wire, effectively avoiding direct contact between the metal parts and the wire, preventing short circuits or arc discharges during live work, and greatly improving work safety.

[0096] The elastic properties of the padding layer enable it to adaptively fill the slight unevenness on the surface of the drain wire. Combined with the anti-slip texture on the surface, it significantly increases the friction of the clamping surface, fundamentally eliminating the sliding and twisting of the drain wire in the clamping hole, preventing the drain wire from swinging, and preventing damage to the drain wire insulation layer.

[0097] Furthermore, the fixing device for preventing lead wire swaying during live working also includes: an insulating rod 150, one end of which is connected to a connecting plate; and a hook 160, which is located at the other end of the insulating rod 150.

[0098] This device mainly includes an insulating rod 150, with a wire hook 160 at the top and a quick-release ratchet pawl mechanism and an anti-slip rubber pad at the bottom.

[0099] The main body of the insulating rod 150 is a 1-meter-long 10kV insulating rod 150, ensuring the insulation distance between the main line and the drain line. The hook 160 at the top allows operators to quickly and easily fix the insulating rod 150 to the main line, and the hook 160 is adaptable to different wire diameters. The quick-release "ratchet pawl" mechanism at the bottom is the core component of the drain line fixing device, mainly composed of a ratchet, a clamping plate with an integrated ratchet pawl, a spring, a side plate, a connecting plate, a movable plate 132, the insulating rod 150, and a fixing device. Its connection relationship is that the ratchet is hinged to the side plate, the ratchet pawl is installed on the movable plate 132 through the pin 134 and is pre-tightened by the spring to make it mesh with the ratchet teeth, the side plate is rigidly connected to the movable plate 132 through the connecting plate, the movable plate 132 is linked to the tail of the insulating rod 150, and the fixing device is fixedly installed at the lower part of the insulating rod 150 as the base of the device. When gripping the drain line, pushing the insulating rod 150 moves the movable plate 132 forward. The pawl slides along the ratchet tooth surface and drives the ratchet to rotate around the hinge axis, closing the clamp to secure the drain line. At the same time, the pawl engages with the ratchet tooth groove to achieve self-locking and prevent loosening. When releasing, pressing the movable plate 132 compresses the spring, causing the movable plate 132 to move downward. The pawl disengages from the ratchet tooth surface, and the ratchet opens to release the drain line. 4. Anti-slip insulating pad: Enables the "ratchet pawl" to reliably fix the drain line.

[0100] One end of the insulating rod 150 is rigidly connected to the fixed base 120 via a connector 110 in the form of a connecting plate, while the other end is fixed to the hook 160 as a whole. The surface of the rod is treated with a special process, giving it excellent insulation and anti-slip properties, ensuring safe isolation between workers and live parts in high-voltage environments.

[0101] Hook 160 is a U-shaped hook structure forged from high-strength aluminum alloy with an anodized insulating finish. Its opening features a resilient locking tongue that automatically locks after hook 160 catches a wire or crossarm, preventing accidental detachment. The hook's curvature is designed to fit the outer contour of common power wires or crossarms, ensuring a secure connection.

[0102] The insulating rod 150 provides sufficient operating length, allowing workers to complete the fixing of the drain line and the attachment of the hook 160 from a safe distance, completely avoiding direct contact between the human body and the high-voltage live conductor, fundamentally eliminating the risk of electric shock, and greatly improving the safety of live-line work.

[0103] The extension function of the insulating rod 150, combined with the hook 160's attachment function, enables the device to reach fixed points such as high or distant conductors and crossarms, significantly expanding the operating range. It is especially suitable for complex operating scenarios with high altitude and large spans, such as overhead lines.

[0104] By using a dual-point fixing method of "clamping module to fix the drainage line + hook 160 to hang the wire / crossarm", a stable force system is formed, which can not only prevent the drainage line from twisting in its own axis, but also effectively limit its swing in the horizontal and vertical directions, thus raising the anti-sway effect to a new level.

[0105] The above embodiments are merely illustrative examples and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
