Description

Technical Field

[0001] The present invention relates to the technical field of power line clamps for electric wires, and particularly to a multifunctional power line clamp. Background Technique

[0002] A wire clamp is an iron or aluminum metal accessory that can be fixed on a wire. Most of them need to bear a large tensile force during operation. Some also need to ensure good electrical contact. Some need to work stably for a long time under high voltage, high load, and complex environments such as humidity, salt spray, and cold. Wire clamps are mainly divided into: equipment wire clamps, fuse wire clamps, wire holding clamps, terminal wire clamps, puncture grounding wire clamps, tension clamps, insulating puncture wire clamps, double-headed wire clamps, lead-in wire clamps, etc.

[0003] Referring to the utility model patent with the Chinese publication number "CN218771000U", it includes a bottom plate. On both sides above the bottom plate, there are fixed plates. On the side of the fixed plate close to the bottom plate, there is a first fixing groove. Between the two fixed plates on the bottom plate, there are two movable blocks. On the side of the movable block close to the fixed plate, there is a limiting groove. Inside the limiting groove, there is a clamping block. On the side of the clamping block close to the fixed plate, there is a second fixing groove that matches the first fixing groove. One end of the clamping block inside the limiting groove is fixedly connected to the side wall of the limiting groove through a first spring. In the middle above the bottom plate, there is a threaded rod, and there is a pressing block on the threaded rod. This kind of power line clamp has a simple structure and is easy to operate. It can clamp power cables of different sizes, effectively improving the versatility of the power line clamp. When the wire expands and contracts due to heat, the first spring can automatically expand and contract, effectively ensuring the safety of using the power line clamp.

[0004] After the existing power line clamps work for a long time in complex environments such as humidity and salt spray, it will cause damage to their surfaces, affecting the work, and cannot ensure that the wire is always in a clamped state during thermal expansion and contraction. This may cause the wire to loosen or fall off from the power line clamp, seriously affecting the work. Summary of the Invention

Moreover, a nano-ceramic coating is sprayed on the surface of the protective housing, isolating the metal part of the power line clamp from corrosive media such as hydrochloric acid, preventing the metal from directly contacting hydrochloric acid and undergoing chemical reactions, thereby preventing the damage of the line clamp structure and the reduction of strength caused by corrosion, ensuring that the line clamp can continuously and stably clamp the power line, guaranteeing the normal and stable operation of the line clamp.

[0015] 2. The multifunctional power line clamp can flexibly handle cables with different diameters and specifications by setting wire clamping blocks. After starting the micro three-phase asynchronous motor, it drives the rotating lead screw to rotate. The rotation of the rotating lead screw drives the first sliding block to move, and through the transmission of the connecting rod, it drives the adjustment of the wire clamping blocks, significantly improving the versatility of the device. It can avoid damage to the insulation layer caused by over-tightening or the risk of detachment caused by over-loosening, improving the safety and reliability of the power line. At the same time, it ensures that the wire is always in a clamped state during thermal expansion and contraction. An insulating anti-slip sleeve is provided on the surface of the wire clamping blocks, effectively isolating the direct metal contact between the wire clamping blocks and the wire, avoiding the risk of electric leakage caused by current conduction through the wire clamping blocks in a high-voltage power environment, and significantly increasing the friction between the clamping blocks and the wire, preventing the wire from loosening or slipping due to vibration, temperature change, or external stress, thus ensuring that the wire clamp can work normally and stably.

[0016] 3. The multifunctional power line clamp can effectively reduce the vibration generated by factors such as line swing under harsh weather conditions such as strong winds and heavy rains by setting the first fixed ring block. Indirectly, it enhances the stable working state of the clamping mechanism in harsh environments, thus ensuring that the wire clamp can work normally and stably.

[0017] 4. The multifunctional power line clamp can effectively buffer the up-and-down, left-and-right vibrations of the wire caused by external factors by setting multiple fifth springs on the surface of the second fixed cylindrical block, and can effectively buffer the front-and-back vibrations of the wire caused by external factors by setting multiple sixth springs on the surface of the second fixed cylindrical block. By setting multiple second springs on the surface of the first fixed cylindrical block, it can effectively buffer the front-and-back, left-and-right vibrations of the wire caused by external factors. By setting multiple third springs on the surface of the first fixed cylindrical block, it can effectively buffer the up-and-down vibrations of the wire caused by external factors, thereby reducing the relative displacement between the wire and the wire clamping blocks, increasing the possibility of the wire clamp working normally and stably. By setting the sixth springs on the surface of the second fixed cylindrical block and multiple third springs on the surface of the first fixed cylindrical block, it ensures that the wire clamp can work normally and stably, and further enhances the buffering effect in cooperation with the first fixed ring block, thus further ensuring that the wire clamp can work normally and stably.

The second sliding block 56 is fixedly connected to the surface of the first connecting sliding rod 58.

[0023] A cylindrical groove is formed inside the protective housing 1, and the surface of the first connecting sliding rod 58 is slidably connected to the groove formed inside the protective housing 1. The second fixing block 51 is slidably connected to the second sliding block 56.

[0026] During use, the inserted electric wire is placed between the two wire clamping blocks. Subsequently, the micro three-phase asynchronous motor is started. The start of the micro three-phase asynchronous motor drives the rotating lead screw to rotate. The rotation of the rotating lead screw drives the first sliding block to move towards the direction close to the micro three-phase asynchronous motor. Subsequently, the movement of the first sliding block drives the connecting rod to slide inside the rotary limiting block, and at the same time makes the rotary limiting block rotate, so that the wire clamping blocks fix the electric wire.

Moreover, by arranging a plurality of sixth springs 512 on the surface of the second fixed cylindrical block 510, the front-and-back vibration of the wire caused by external factors can be effectively buffered.

And by arranging the sixth springs 512 on the surface of the second fixed cylindrical block 510 and arranging a plurality of third springs 55 on the surface of the first fixed cylindrical block 53, the normal and stable operation of the wire clamp is ensured. And under the combined action with the first fixed ring block 41, the buffering effect is further enhanced, thereby further ensuring the normal and stable operation of the wire clamp.

[0028] Embodiment 2: Please refer to Figures 1-8 , on the basis of Embodiment 1, the present invention provides a technical solution: The external shock-absorbing mechanism 4 includes a first spring 42. One end of the first spring 42 is fixedly connected inside the protective housing 1, and the other end of the first spring 42 is fixedly connected with a first fixed ring block 41. The first fixed ring blocks 41 are symmetrically distributed on both sides of the central axis of the protective housing 1. The number of the first fixed ring blocks 41 is four, and they are arranged in two-by-two central symmetry.

[0029] The clamping mechanism 2 includes a micro three-phase asynchronous motor 21. The micro three-phase asynchronous motor 21 is fixedly connected inside the shock-proof support block 3. A rotating lead screw 22 is rotatably connected inside the micro three-phase asynchronous motor 21. The end of the rotating lead screw 22 is fixedly connected with a first fixed block 25. The first fixed block 25 is fixedly connected to the surface of the shock-proof support block 3. The first fixed blocks 25 are symmetrically distributed on both sides of the central axis of the shock-proof support block 3.

[0030] There are two first fixed blocks 25. A first sliding block 23 is slidably connected to the surface of the rotating lead screw 22. A rotating limit block 24 is rotatably connected to the surface of the first sliding block 23 through a rotating shaft. A connecting rod 26 is slidably connected inside the rotating limit block 24.

[0031] There are two wire clamping blocks 27. An insulating anti-slip sleeve 28 is fixedly connected to the surface of the wire clamping block 27. The connecting rod 26 is rotatably connected inside the first fixed block 25. An inclined groove is opened at the top of the protective housing 1, and an inclined groove and a through groove are opened inside the protective housing 1 During use, after fixation, when the wire is affected by the outside world, the shaking of the wire drives the anti-vibration support block to shake together. At this time, when the anti-vibration support block shakes up and down or left and right, the anti-vibration support block will compress the fifth spring and the third spring, and at the same time will also compress the second spring, so as to make the impact force generated by the spring buffer. When the anti-vibration support block shakes back and forth, the anti-vibration support block will compress the second spring and the sixth spring, so as to make the impact force generated by the spring buffer, so that the wire is more stable. At the same time as the wire shakes, the first spring further buffers it, so as to ensure the normal and stable operation of the wire clamp.

[0032] By setting the protective housing, it effectively blocks moisture and humidity from entering the inside of the clamping mechanism, prevents metal parts from rusting and corroding, and avoids affecting the normal operation of the wire clamp due to moisture. And a nano-ceramic coating is sprayed on the surface of the protective housing 1 to isolate the metal part of the power wire clamp from corrosive media such as hydrochloric acid, and avoid the chemical reaction of the metal directly contacting hydrochloric acid, so as to prevent the damage of the wire clamp structure and the reduction of strength caused by corrosion, ensure that the wire clamp can continuously and stably clamp the power line, and ensure that the wire clamp can work normally and stably. And inclined grooves are opened at the top and inside of the protective housing 1, which is beneficial to quickly drain rainwater, and avoid the ice formation of accumulated water in cold areas from affecting the performance of the wire clamp, so as to further ensure that the wire clamp can work normally and stably.

[0033] By setting the wire clamping block 27, after starting the micro three-phase asynchronous motor 21, it will drive the rotating lead screw 22 to rotate. The rotation of the rotating lead screw 22 will drive the first sliding block 23 to move, and drive the adjustment of the wire clamping block 27 through the transmission of the connecting rod, which can flexibly cope with wires of different diameters and specifications, significantly improving the versatility of the equipment, avoiding damage to the insulation layer caused by over-tightening or the risk of falling off caused by over-loosening, improving the safety and reliability of the power line, and at the same time ensuring that the wire is always in a clamped state during thermal expansion and contraction. And an insulating anti-slip sleeve 28 is arranged on the surface of the wire clamping block 27, which effectively isolates the direct metal contact between the wire clamping block 27 and the wire, avoids the risk of electric leakage caused by the conduction of current through the wire clamping block 27 in a high-voltage power environment, and significantly increases the friction between the clamping block and the wire, preventing the wire from loosening or slipping due to vibration, temperature change or external stress, so as to ensure that the wire clamp can work normally and stably.

[0034] By setting the first fixed ring block 41, it can effectively reduce the vibration generated by the swing of the line, etc. in bad weather such as strong wind and heavy rain. The first fixed ring block 41 can initially buffer the vibration, indirectly enhancing the stable working state of the clamping mechanism 2 in a harsh environment, so as to ensure that the wire clamp can work normally and stably The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
