Description

Technical Field

[0001] The utility model belongs to the technical field of electric power safety, and more specifically, particularly relates to an alarm device for preventing external force damage to a power transmission line. Background Art

[0002] Power transmission is achieved by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. According to the structural form, the transmission line is divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. According to the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission.

[0003] Based on the above, the inventors have discovered the following problems: lines are installed on some roads or culverts, and the cables will become loose as the usage time increases. Some vehicles may scratch the cables installed on the poles during driving due to their high height, and in severe cases, the cables may break. This not only affects the use of the lines, but also creates unnecessary personal safety hazards.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and an alarm device for preventing external force damage to a power transmission line is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the transmission line anti-external force damage alarm device of the utility model are achieved by the following specific technical means:

[0006] A transmission line anti-external force damage alarm device comprises a mounting seat, a support rod is inserted and installed on one side of the mounting seat, a column insulator is installed on the top end surface of the support rod, and a trigger assembly is installed on the bottom end surface of the support rod, the trigger assembly comprises a mounting box, both side outer walls of the mounting box are provided with mounting grooves, an L-shaped clamping plate is inserted and installed in the mounting groove through a locking assembly, a through hole is opened on the surface of the L-shaped clamping plate, and the L-shaped clamping plate is assembled and installed with the support rod through the through hole and screws.

[0007] Furthermore, there are two groups of L-shaped clamps, one of which is concave and has a tooth groove on the inner wall, and the other is convex and has a groove on the inner wall, a gear is installed in the groove through an assembly part, and the gear is meshed with the tooth groove.

[0008] Furthermore, the locking assembly includes a chamber formed on the outer wall of one of the L-shaped clamping plates, a limiting groove is formed in the chamber, a T-shaped block is installed between the limiting grooves, and a spring is installed on one side of the T-shaped block in the chamber.

[0009] Furthermore, the other two outer walls of the installation box are penetrated by assembly holes, and the diameter of the assembly holes matches the diameter of the T-block.

[0010] Furthermore, a rope is installed inside the installation box through a spring coiler, a round block is installed at one end of the rope, and a hook is installed at one side of the round block.

[0011] Furthermore, a trigger is installed below an outer wall of one side of the installation box, and the trigger is connected to the PC end and the mobile end through a signal.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Through the use of L-shaped clamping plates, T-shaped blocks, springs and assembly holes, when the spacing between the L-shaped clamping plates needs to be changed, the T-shaped blocks are pressed and then stretched to the specified positions on both sides. At this time, the T-shaped blocks are subjected to the reaction force of the springs, forcing the T-shaped blocks to be engaged in the assembly holes, so that the L-shaped clamping plates can be fixed on the installation box, so that the alarm device can be used with different types of power transmission lines, greatly improving the assembly line;

[0014] The rope is used in conjunction with a spring winder. When the rope breaks, the spring winder can reel the rope in. When it is reeled to a certain position, the round block will contact the surface of the trigger. When the trigger receives a trigger signal, it can send it to the PC and mobile terminals through the signal receiver inside the trigger, thereby reminding the staff that there are hidden dangers on the current line.
