Description

Technical Field

[0001] This utility model relates to the field of conductor fixing clamp technology, and in particular to a stable conductor fixing clamp for 10kV overhead lines. Background Technology

[0002] In the field of 10kV overhead power line engineering, the secure fixing of conductors is crucial to ensuring stable power transmission. The 10kV overhead line sturdy conductor fixing clamp, as a key component specifically designed to fix conductors in 10kV overhead lines, directly affects the reliability and safety of line operation. To solve the above-mentioned problems and meet the requirements for safe and stable operation of 10kV overhead lines, the sturdy conductor fixing clamp has emerged. Compared with traditional binding methods, the sturdy conductor fixing clamp has many advantages.

[0003] However, existing 10kV overhead line stabilized conductor clamps have the following disadvantages:

[0004] (1) Traditional wire fixing methods are often difficult to adjust the height flexibly, or the adjustment process requires complex tools and multiple steps, resulting in low construction efficiency, high labor intensity, and easy loosening in environments such as strong winds and vibrations, making it difficult to adapt to different terrains and erection height requirements.

[0005] (2) Traditional fasteners can usually only be used for conductors of a specific diameter. When dealing with conductors of different cross sections in 10kV lines, it is necessary to customize fasteners of various specifications, which leads to increased costs and low construction efficiency. In addition, during the clamping process, the conductor may slip off due to size mismatch or the conductor insulation layer may be worn due to hard contact, affecting the safe operation of the line.

[0006] Therefore, this utility model provides a stable conductor fixing clamp for 10kV overhead lines. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4 The present invention provides a technical solution: a 10kV overhead line stable conductor fixing clamp, including an installation rod 1, a circular groove is provided on the top of the installation rod 1, a telescopic rod 101 is movably connected to the inner side wall of the circular groove, a cavity is provided inside the installation rod 1, an adjustment component 2 is provided inside the cavity, and a fixing component 3 is provided on the top of the telescopic rod 101.

[0029] The adjustment component 2 includes a gear 201 rotatably connected to the inner wall of the cavity, which converts the linear motion of the second rack 203 into its own rotational motion, and then drives the first rack 202 to make a reverse linear motion, thereby realizing the extension and retraction of the locking block 206. The surface of the gear 201 is meshed with the first rack 202 and the second rack 203. A pressing block 204 is fixedly connected to one side of the second rack 203. When pressed, the second rack 203 is pushed to compress the spring 205 and move. When released, the second rack 203 is driven to reset under the action of the spring 205. One end of the pressing block 204 is connected to the inner wall of the cavity with the spring 205. A locking block 206 is fixedly connected to one side of the first rack 202. By engaging or disengaging the locking slot of the telescopic rod 101, the relative fixation or unlocking of the telescopic rod 101 and the mounting rod 1 can be directly realized. The surface of the telescopic rod 101 has multiple locking slots that are adapted to the locking block 206. One end of the locking block 206 is engaged in the interior of one of the locking slots.

[0030] The fixing assembly 3 includes a first clamping plate 301 mounted on the top of the telescopic rod 101. A second clamping plate 302 is rotatably connected to one side of the top of the first clamping plate 301 and can be flipped over to cover the first clamping plate 301. The wire is pressed into the arc-shaped groove of the clamping block 303 by the closing fit with the first clamping plate 301. Multiple mounting grooves are opened on the opposite side of the first clamping plate 301 and the second clamping plate 302. The inner sidewall of the mounting groove is provided with the clamping block 303. The arc-shaped groove on the surface is adapted to the shape of the wire. By changing the diameter of different arc-shaped grooves, the wire can be pressed into the arc-shaped groove. The clamping block 303 enables the fixing component 3 to adapt to wires of various specifications. The bottom of the clamping block 303 and the inner bottom wall of the mounting groove are provided with grooves. The first magnetic block 304 and the second magnetic block 305 are respectively installed in the groove of the clamping block 303 and the groove of the mounting groove. The clamping block 303 is quickly fixed in the mounting groove by the magnetic force of opposite poles attracting each other, which facilitates the replacement and positioning of the clamping block 303. The first magnetic block 304 and the second magnetic block 305 are compatible. The surface of each clamping block 303 is provided with an arc-shaped groove that is compatible with wires of different diameters.

[0031] A connecting block 4 is fixedly connected to one side of the first clamping plate 301, and a fixing block 5 is fixedly connected to one side of the second clamping plate 302. The top of the fixing block 5 is provided with an installation hole, and a screw 6 is provided inside the installation hole. The top of the connecting block 4 is provided with a threaded hole that matches the screw 6. By fastening the screw 6 to the threaded hole of the connecting block 4, the first clamping plate 301 and the second clamping plate 302 can be firmly locked, ensuring that the clamping force on the wire is stable and reliable, and avoiding the clamping plates from loosening due to vibration, wind, or other factors.

[0032] The bottom of the mounting rod 1 is fixedly connected to a fixing stake 7, which is arranged in a cross shape. The cross-shaped fixing stake 7 increases the contact area and gripping force between the mounting rod 1 and the mounting foundation, effectively dispersing the tension of the wire and its own weight on the fixing clamp, and significantly improving the overall stability and anti-overturning ability of the installation.

[0033] The surface of the telescopic rod 101 is fixedly connected to a limiting block 8. The inner side wall of the circular groove is provided with a limiting groove that matches the limiting block 8. The limiting block 8 is movably connected inside the limiting groove. The limiting block 8 can restrict the rotation of the telescopic rod 101, ensuring that the fixing component 3 always maintains the correct installation direction, and avoiding the safety hazards or installation failures caused by the parts falling off during the adjustment process.

[0034] Positioning blocks 9 are fixedly connected to both sides of the clamping block 303. The inner side wall of the mounting groove is provided with a positioning groove that matches the positioning block 9. The positioning block 9 can accurately limit the installation position of the clamping block 303, ensure that the arc grooves of the upper and lower clamping blocks 303 are aligned, and avoid uneven force on the wire or unstable clamping due to the offset of the clamping block 303.

[0035] A protective pad 10 is fixedly connected to the inner wall of the arc groove. The protective pad 10 is made of rubber. The protective pad 10 can increase the friction coefficient between the wire and the clamp 303 and prevent the wire from slipping under vibration or wind.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: When the spring 205 is in its natural extended state, it pushes the second rack 203 and the pressing block 204 outward, and at the same time drives the gear 201 that meshes with it to rotate, causing the first rack 202 to move towards the telescopic rod 101. Finally, the locking block 206 is locked into the slot on the surface of the telescopic rod 101, fixing the telescopic rod 101 relative to the mounting rod 1. The height of the fixing component 3 remains stable. When the pressing block 204 is pressed, the second rack 203 compresses the spring 205 and moves inward, driving the gear 201 to rotate in the opposite direction, thereby causing the first rack 202 to drive the locking block 206 to disengage from the slot. At this time, the telescopic rod 101 is unlocked and can slide up and down along the circular groove of the mounting rod 1 to adjust to the required height. After releasing the pressing block 204, the spring 205 returns to its original position, pushing the second rack 203 to return to its original position. The gear 201 rotates forward again, causing the locking block 206 to re-engage into the corresponding slot. The telescopic rod 101 is locked again, and the height of the fixing component 3 is fixed.

[0038] The second step: Each clamp 303 has an arc-shaped groove of different diameter on its surface, which can match various specifications of conductors in 10kV overhead lines. The clamp 303 and the mounting groove are fixed by the magnetic attraction of the first magnetic block 304 and the second magnetic block 305. At the same time, the positioning block 9 cooperates with the positioning groove to ensure that the clamp 303 is installed in a precise position. When it is necessary to clamp conductors of different diameters, simply overcome the magnetic force to remove the current clamp 303 and replace it with a clamp 303 with an arc-shaped groove of the corresponding diameter. Place the conductor into the arc-shaped groove of the clamp 303 of the first clamping plate 301, rotate the second clamping plate 302 to cover the conductor, and lock it by the screw 6 and the threaded hole of the connecting block 4, so that the arc-shaped grooves of the upper and lower clamps 303 together wrap the conductor. The rubber protective pad 10 can increase the friction and avoid wear on the surface of the conductor, ensuring that conductors of different diameters can be firmly clamped.
