Description

Technical Field

[0001] This utility model relates to a clamping mechanism, specifically a wire clamping mechanism, belonging to the field of circuit testing technology. Background Technology

[0002] During the transmission of high-voltage circuits, when a fault occurs in the line, it is necessary to inspect and repair the transmission line. Before the inspection and repair, it must be ensured that the line has been completely de-energized and the grounding wire has been correctly connected to prevent accidental energization of the circuit due to operational negligence, which could cause personal injury or death.

[0003] However, traditional operating methods require maintenance personnel to wear full protective gear, carry electrical testing equipment and grounding wires to climb iron towers tens or even hundreds of meters high to complete electrical testing and the connection and removal of grounding wires. This is labor-intensive, risky, and when connecting grounding wires to high-voltage power lines, most of them are connected by bolts, which is cumbersome and prone to loosening and falling off.

[0004] With the application of intelligent devices such as drones in the power industry, there is an urgent need for a conductor clamp mechanism that is adaptable to remote control, provides stable clamping, is highly versatile, and facilitates grounding wire connection, in order to reduce the risks of high-altitude operations and improve the efficiency of line maintenance. Based on this, the present invention aims to provide a conductor clamp mechanism that solves the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a wire clamping mechanism to solve the above problems. Under the control of the drive motor, the lead screw can control the sliding of the clamping plate, which is conducive to the clamping plate moving closer to the other clamping plate to clamp the wire. At the same time, since the bottom side of the other clamping plate has a certain slope, the bottom gap between the two clamping plates becomes smaller and smaller, which is conducive to the clamped wire not slipping off.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a wire clamping mechanism includes a housing, a clamping mechanism installed at one end of the housing, the clamping mechanism including a support frame, the support frame installed at one end of the housing, two clamping plates installed at the bottom of one end of the support frame, one of the clamping plates having a certain slope on one side of its bottom, the other clamping plate being slidably connected to the top of the support frame, two sliding rods slidably connected at one end of the housing, one end of the two sliding rods being connected to one side of the clamping plate, the other end of the two sliding rods being connected through a mounting plate, the mounting plate being slidably connected to the inside of the housing through the two sliding rods, a drive motor being installed on the mounting plate, a lead screw threadedly connected at the center of one end of the housing, one end of the lead screw being rotatably connected to one side of the clamping plate, the other end of the lead screw being connected to the output shaft of the drive motor.

[0007] Preferably, the support frame has a movable groove on the inner side of its bottom, and the top of one of the clamping plates is slidably connected to the inside of the movable groove.

[0008] Preferably, the movable groove is of a "convex" shape structure, two sides of the top of the clamping plate are respectively rotatably connected with guide wheels, and the guide wheels are in rolling connection with the inner side of the movable groove.

[0009] Preferably, the bottoms of the two clamping plates are respectively detachably connected with guide plates through bolts, and a certain included angle is formed between the two guide plates.

[0010] Preferably, a battery is mounted on the inner side of the top of the housing, and the support frame is of an "L" shape structure.

[0011] Preferably, one side of one of the clamping plates is of a toothed structure, and the two clamping plates have equal lengths.

[0012] Preferably, one side of the bottom of one of the clamping plates is vertically connected with an anti-collision rod, and the anti-collision rod is located at one end of the housing.

[0013] Preferably, a wiring mechanism is mounted on the other clamping plate, the wiring mechanism comprises a wiring box, the outer side of the top of the clamping plate is detachably connected with the wiring box, two ends of the wiring box are provided with slots, the top of the wiring box is mounted with a cover plate through bolts, the top of the cover plate is vertically and threadedly connected with a screw rod, the screw rod extends to the inner side of the wiring box, a pressing plate is slidably connected to the inner side of the wiring box, and the bottom of the screw rod is rotatably connected with the top of the pressing plate.

[0016] The beneficial effects of the utility model are as follows: through the installation of the support frame, it is beneficial to install the two clamping plates. Since one of the clamping plates can slide relative to the support frame, under the control of the drive motor, the screw rod is in threaded rotation with the end of the housing, and under the cooperation of the two slide rods, the drive motor will not rotate on its own. At this time, the screw rod can control the sliding of the clamping plate, which is beneficial for the clamping plate to approach the other clamping plate to realize clamping the electric wire. Meanwhile, since one side of the bottom of the other clamping plate has a certain slope, the gap at the bottom between the two clamping plates becomes smaller and smaller, which is beneficial to prevent the clamped wire from slipping off.

[0022] As a technical optimization solution of the present utility model, the movable groove 210 is of a "convex" structure, two sides of the top of the clamping plate 202 are respectively rotatably connected with guide wheels 211, the guide wheels 211 are in rolling connection with the inner side of the movable groove 210. The installation of the guide wheels 211 facilitates rolling inside the movable groove 210, enables the clamping plate 202 to slide smoothly without falling off.

[0023] As a technical optimization solution of the present utility model, the bottoms of the two clamping plates 202 are respectively and detachably connected with guide plates 203 through bolts, and a certain included angle is formed between the two guide plates 203. By installing the two guide plates 203 at the bottoms of the two clamping plates 202, the bottoms of the clamping plates 202 are extended, which is beneficial for the high-altitude electric wire to be guided into the space between the two clamping plates 202 for clamping, playing a guiding role.

[0024] As a technical optimization solution of the present utility model, a battery 208 is installed on the inner side of the top of the cover shell 1, and the support frame 201 is of an "L" shaped structure. The installation of the battery 208 is beneficial for supplying power to the drive motor 204, and enables the support frame 201 to be stably installed at one end of the cover shell 1 with better supporting strength.

[0025] As a technical optimization solution of the present utility model, one side of one of the clamping plates 202 is of a toothed structure, and the two clamping plates 202 have the same length. The provision of the toothed structure facilitates the two clamping plates 202 to stably clamp the electric wire without slipping off.

[0026] As a technical optimization solution of the present utility model, one side of the bottom of one of the clamping plates 202 is vertically connected with an anti-collision rod 209, and the anti-collision rod 209 is located at one end of the cover shell 1. The installation of the anti-collision rod 209 prevents the clamping plate 202 from being damaged by collision with the cover shell 1 when sliding, playing a protective role.

[0027] As a technical optimization solution of the present utility model, another clamping plate 202 is provided with a wiring mechanism 3, the wiring mechanism 3 includes a wiring box 301, the outer side of the top of the clamping plate 202 is detachably connected with the wiring box 301, two ends of the wiring box 301 are provided with slots 302, the top of the wiring box 301 is provided with a cover plate 303 through bolts, the top of the cover plate 303 is vertically and threadedly connected with a screw rod 304, the screw rod 304 extends to the inner side of the wiring box 301, the inner side of the wiring box 301 is slidably connected with a pressing plate 307, and the bottom of the screw rod 304 is rotatably connected with the top of the pressing plate 307. Through the installation of the wiring box 301, the pressing plate 307 is installed under the cooperation of the cover plate 303. With the cooperation of the slots 302, the grounding wire can be easily inserted. By rotating the screw rod 304, the screw rod 304 drives the pressing plate 307 to squeeze and clamp the grounding wire inside the wiring box 301, so as to realize the connection between the grounding wire and the clamping plate 202.

[0028] As a technical optimization of this utility model, the screw 304 has a "T" shaped structure, and the length of the screw 304 is greater than the internal depth of the junction box 301. The junction box 301 and the pressure plate 307 are both "L" shaped structures, which facilitates the operation of the screw 304 and ensures that the grounding wire is tightly clamped. Furthermore, the "L" shaped design of the junction box 301 and the pressure plate 307 serves to prevent detachment.

[0029] As a technical optimization of this utility model, two guide rods 306 are vertically slidably connected to one end of the cover plate 303. The two guide rods 306 are elastically connected to the cover plate 303 through a compression spring 305. The bottom of the two guide rods 306 extends to the inside of the junction box 301 and is vertically connected to the top of the pressure plate 307. The installation of the two guide rods 306 helps to guide the pressure plate 307 when it slides. With the cooperation of the compression spring 305, the two guide rods 306 pull the pressure plate 307, so that the pressure plate 307 remains stable and does not loosen.

[0030] In use, this invention first inserts the grounding wire into the junction box 301, then rotates the screw 304 to press the grounding wire against the pressure plate 307, ensuring a secure connection between the grounding wire and the junction box 301. The junction box 301 and pressure plate 307 are both designed with an "L" shape to prevent detachment. Finally, the drive motor 204 is controlled to move the two clamping plates 202 apart, creating a gap. The drone then connects the casing 1, carrying the casing 1 and the two clamping plates 202 to a designated altitude. The drone aligns the two clamping plates 202 with the power line in the air. With the cooperation of the two guide plates 203, the power line smoothly enters the space between the two clamping plates 202. By controlling the drive motor 204 to work again, the drive motor 204 controls the lead screw 207 to rotate, thereby moving one of the clamping plates 202 closer to the other clamping plate 202 to clamp the power line. At the same time, because the bottom side of the other clamping plate 202 has a certain slope, the bottom gap between the two clamping plates 202 becomes smaller and smaller, which helps to prevent the clamped wire from slipping.
