Description

Technical Field

[0001] This utility model relates to the field of power line technology, specifically to an alarm device for power lines. Background Technology

[0002] Power lines are lines used to transmit electrical energy between power plants, substations, and power users; they are an important part of the power supply system and are responsible for transmitting and distributing electrical energy.

[0003] Currently, alarm devices installed on power lines generally require specialized installation tools to mount them onto the cables. However, due to the varying thicknesses of the cables, current alarm devices cannot be easily adjusted in size, necessitating the use of external supports for installation and fixation. This results in inconvenient installation and increased costs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide an alarm device for power lines, comprising:

[0005] Fixing plate;

[0006] Two first clamping mechanisms are disposed opposite each other at both ends of the top of the fixed plate. The two first clamping mechanisms are movable along a first direction or a second direction, and the two ends of the two first clamping mechanisms can move closer to or further away from each other along the first direction, and the two first clamping mechanisms can move closer to or further away from each other along the second direction.

[0007] A first mounting bracket is disposed at the bottom of the fixed plate;

[0008] The first displacement mechanism is rotatably disposed within the first mounting frame, and the first displacement mechanism passes through the fixed plate and is connected to the two first clamping mechanisms in a transmission manner, so as to drive the two first clamping mechanisms to move closer to or further away from each other along the second direction;

[0009] The first limiting mechanism is rotatably disposed at the bottom of the first displacement mechanism.

[0054] The above-described solution of this utility model has at least the following beneficial effects:

[0055] The cable is placed between the two first clamping mechanisms and the two second clamping mechanisms. The drive mechanism rotates clockwise, moving the movable plate towards the fixed plate, so that the two second clamping mechanisms abut against the cable. Then, the first and second displacement mechanisms are rotated as needed to move the two first and two second clamping mechanisms to the desired positions in the second direction. Next, the two first and two second clamping mechanisms are moved in the second direction until their ends approach the cable and clamp it. Finally, the first and second limiting mechanisms move the clamping mechanisms towards the cable. The first limiting mechanism is rotated counterclockwise and clockwise to press the bottom of the first displacement mechanism, causing the bottom of the first displacement mechanism to expand outward and abut against the inner side of the first mounting bracket. The friction between the bottom of the first displacement mechanism and the first mounting bracket fixes the first displacement mechanism in place, preventing it from moving. This ensures that the two first clamping mechanisms will not shift during use. The second limiting mechanism also presses the top of the second displacement mechanism, causing the top of the second displacement mechanism to expand outward and generate friction with the second mounting bracket, preventing the second displacement mechanism from moving. This also ensures that the two second clamping mechanisms will not shift during use.

[0056] The first displacement mechanism, the first limiting mechanism, the driving mechanism, the second displacement mechanism, and the second limiting mechanism enable the two first clamping mechanisms and the two second clamping mechanisms to adapt to cables of different sizes, and the installation does not require the use of external tools, saving installation time and costs.

[0077] The alarm device for power lines according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0078] Please see Figures 1-6In this embodiment, the device includes: a fixed plate 1; two first clamping mechanisms 2, which are disposed opposite each other at both ends of the top of the fixed plate 1. The two first clamping mechanisms 2 are movable along a first direction 12 or a second direction 13, and the ends of the two first clamping mechanisms 2 can move closer to or further away from each other along the first direction 12, and the ends of the two first clamping mechanisms 2 can move closer to or further away from each other along the second direction 13; a first mounting bracket 3, which is disposed at the bottom of the fixed plate 1; and a first displacement mechanism 4, which is rotatably disposed within the first mounting bracket 3 and passes through the fixed plate 1 and the two first clamping mechanisms 2. A clamping mechanism 2 is driven to move two first clamping mechanisms 2 closer to or further apart along a second direction 13; a first limiting mechanism 5 is rotatably located at the bottom of the first displacement mechanism 4. When the first limiting mechanism 5 rotates counterclockwise, it presses against the bottom of the first displacement mechanism 4, causing the bottom of the first displacement mechanism 4 to expand outward and abut against the inner side of the first mounting bracket 3, thus locking the first displacement mechanism 4 within the first mounting bracket 3; a driving mechanism 6 is located on the fixed plate 1 and can rise or fall along a third direction 14; a movable plate 7 is also included. The first clamping mechanism 2 is mounted on the drive mechanism 6 to be driven by the drive mechanism 6 to rise or fall along a third direction 14; two second clamping mechanisms 8 are respectively mounted opposite each other at both ends of the bottom of the movable plate 7. The two second clamping mechanisms 8 are movable along the first direction 12 or the second direction 13, and the two ends of the two second clamping mechanisms 8 can move closer or further away from each other along the first direction 12, and the two second clamping mechanisms 8 can move closer or further away from each other along the second direction 13, so as to clamp the cable together with the two first clamping mechanisms 2; a second mounting bracket 9 is mounted on the top of the movable plate 7; a second displacement mechanism 10. The second displacement mechanism 10 is rotatably disposed within the second mounting bracket 9, and the second displacement mechanism 10 is connected to the two second clamping mechanisms 8 through the fixed plate 1, so as to drive the two second clamping mechanisms 8 to move closer or further away from each other along the second direction 13; the second limiting mechanism 11 is rotatably disposed on the top of the second displacement mechanism 10. When the limiting mechanism rotates in the clockwise direction, the second limiting mechanism 11 presses the top of the second displacement mechanism 10, so that the bottom of the second displacement mechanism 10 expands outward and abuts against the inner side of the second mounting bracket 9, so that the second displacement mechanism 10 is locked in the second mounting bracket 9;The cable is placed between the two first clamping mechanisms 2 and the two second clamping mechanisms 8. Then, the drive mechanism 6 rotates clockwise, causing the movable plate 7 to move towards the fixed plate 1, so that the two second clamping mechanisms 8 abut against the cable. Subsequently, the first displacement mechanism 4 and the second displacement mechanism 10 are rotated respectively as needed, so that the two first clamping mechanisms 2 and the two second clamping mechanisms 8 move towards the desired position in the second direction 13. Then, the two first clamping mechanisms 2 and the two second clamping mechanisms 8 are moved towards the second direction 13 respectively, so that the two ends of the two first clamping mechanisms 2 and the two ends of the two second clamping mechanisms 8 move closer to the cable until the cable is clamped. Finally, the cable is separated by the first limiting mechanism 5 and the second limiting mechanism 11. Do not rotate in the counterclockwise or clockwise direction, so that the first limiting mechanism 5 presses the bottom of the first displacement mechanism 4, so that the bottom of the first displacement mechanism 4 expands outward and abuts against the inner side of the first mounting bracket 3. Through the friction generated between the bottom of the first displacement mechanism 4 and the first mounting bracket 3, the first displacement mechanism 4 is fixed and cannot move, thereby ensuring that the two first clamping mechanisms 2 will not be displaced during use. The second limiting mechanism 11 also presses the top of the second displacement mechanism 10, so that the top of the second displacement mechanism 10 expands outward and generates friction with the second mounting bracket 9, so that the second displacement mechanism 10 can no longer move, thereby ensuring that the two second clamping mechanisms 8 will not be displaced during use.

[0079] The first displacement mechanism 4, the first limiting mechanism 5, the driving mechanism 6, the second displacement mechanism 10, and the second limiting mechanism 11 enable the two first clamping mechanisms 2 and the two second clamping mechanisms 8 to adapt to cables of different sizes, and the installation does not require the use of external tools, saving installation time and costs.

The screw is rotated so that the third screw 502 abuts against the silicone tube 404. The screw 502 is rotated further so that the first spring 405 inside the silicone tube 404 is actuated and compressed. The silicone tube 404 is squeezed outward by the screw, so that the outer circumferential surface of the silicone tube 404 abuts against the inner circumferential surface of the first mounting bracket 3. The friction between the silicone tube 404 and the first mounting bracket 3 fixes the rotating shaft 401 so that it cannot rotate, thereby keeping the sliding plates 202 on both sides in the adjusted position.
