Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line protection, and in particular to an electrical safety early warning device for power pole tower power transmission lines. Background Art

[0002] Overhead transmission lines are an important part of the power grid and power system. Every year, high-voltage transmission lines are damaged by external forces, resulting in frequent disconnection and power outages, which further cause serious consequences of large-scale and long-term power outages in local areas. Once such large-scale and long-term power outages occur, they will not only greatly affect the daily lives of local residents, but also cause huge economic losses to local development. Therefore, when power equipment is damaged by external unstable factors, it is required to be able to monitor and warn in time and to repair facilities and equipment in a timely and efficient manner after failure. Therefore, it is necessary to use transmission line electrical safety warning devices to provide safety warnings for transmission lines. Utility Model Content

[0003] The utility model aims to provide an electrical safety early warning device for a power transmission line of an electric pole tower to solve the problems mentioned in the above background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An electrical safety early warning device for a power transmission line of an electric pole tower comprises a base 1 and a ground wire 14, a connecting seat 2 is arranged above the base 1, and an electric box 3 is arranged above the connecting seat 2;

[0006] A servo motor 12 is installed on one side of the base 1, and the output end of the servo motor 12 is fixedly connected to a bidirectional threaded rod 25 which is transversely arranged in the base 1, and a sliding block 17 is respectively sleeved on the two ends of the bidirectional threaded rod 25, and the sliding block 17 is threadedly connected to the bidirectional threaded rod 25, and a mounting block 24 is arranged above the sliding block 17;

[0007] A slide groove is provided above the base 1 at a position directly opposite to the bidirectional threaded rod 25, and a support rod 11 is hingedly provided above each mounting block 24, and the other end of the support rod 11 passes through the slide groove and is hingedly connected to the bottom end of the connecting seat 2;

[0008] A water level sensor 15 is installed at the bottom end of the connecting base 2 , and an early warning control module 10 is arranged in the electrical box 3 . The water level sensor 15 is electrically connected to the early warning control module 10 , and the early warning control module 10 is electrically connected to the servo motor 12 .

[0009] Through the above technical solution, when the water level sensor senses the water level, the servo motor is started, and the servo motor drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod can drive the two sliding blocks closer to each other and then drive the support rod to make the connecting seat and the electrical box rise, preventing water from entering the interior of the electrical box and causing damage to the components.

[0010] Furthermore, both sides of the bottom end of the base 1 are provided with limiting slide grooves 16 matching with the sliding block 17 , and the lower end of the sliding block 17 is slidably disposed in the limiting slide grooves 1 .

[0011] Through the above technical solution, the limiting sliding groove can limit the sliding block when the sliding block moves, thereby improving the stability of the sliding block when moving, and further ensuring the stability of the entire device.

[0012] Furthermore, a shell 4 is provided at the lower end of the interior of the electrical box 3, one end of the ground wire 14 is provided inside the shell 4, the ground wire 14 passes through the connecting seat 2 and the base 1 in sequence, and the early warning control module 10 is provided in the shell 4; an alarm 7 is installed above the electrical box 3, a support plate 9 is fixedly provided on one side of the interior of the electrical box 3, a display screen 5 is provided above the support plate 9, and the early warning control module 10 is electrically connected to the display screen 5 and the alarm 7.

[0013] Through the above technical solution, when the transmission line is damaged by external force, causing accidents such as disconnection and power outage, the early warning control module will obtain the result and display it on the display screen. At the same time, the early warning control module will control the alarm to sound an alarm.

[0014] Furthermore, a hose 13 is provided at the bottom end of the housing 4 , and the hose 13 is sleeved on the outside of the ground wire 14 .

[0015] Through the above technical solution, the hose can protect the leaking ground wire to prevent the ground wire from being damaged during use.

Specifically, four groups of dampers 23 are provided, which are respectively located at the four corners of the electric box 3.

[0017] Through the above technical solution, when an object falls, the protective plate will squeeze the buffer spring, and the buffer spring will cushion the protective plate and the object through its own elasticity, reducing the impact force of the object, thereby protecting the electrical box and preventing the top of the electrical box and the alarm from being damaged. The damper inside the buffer spring can limit the protective plate to prevent the buffer spring from shaking too much, thereby improving stability.

[0018] Furthermore, a hook 8 is provided at the top of the inner wall of the electrical box 3 , and a water-absorbing particle bag 22 is hung below the hook 8 .

[0019] Through the above technical solution, the water-absorbing particle bag at the bottom of the hook can absorb moisture inside the electrical box to prevent the components inside the electrical box from being affected by moisture. When the water-absorbing particle bag needs to be replaced, the water-absorbing particle bag 22 can be taken out from the hook. The structure is simple and easy to install and disassemble.

[0020] Furthermore, a box door 19 is movably hinged on one side of the electric box 3 , and a handle 18 is fixedly connected to the box door 19 .

[0021] Compared with the prior art, the utility model of the power transmission line electrical safety early warning device has the following beneficial effects:

[0022] (1) By providing a support rod, a servo motor, a water level sensor, a limit slide groove, a bidirectional threaded rod, etc., when the water level sensor senses the water level, the servo motor is started, and the servo motor drives the threaded rod to rotate. Since the threads on the outside of the threaded rod are opposite and the threaded rod and the sliding block cooperate with each other, the rotation of the threaded rod can make the sliding block drive the support rod to move, so that the support rod can drive the connecting seat and the electric box to rise, preventing water from entering the interior of the electric box and causing damage to the components. The limit slide groove can limit the sliding block to improve the stability of the device;

[0023] (2) By providing a water-absorbing particle bag, the moisture inside the electric box can be absorbed to prevent the components inside the electric box from being affected by the moisture. When the water-absorbing particle bag needs to be replaced, the hanging ring at the top of the water-absorbing particle bag can be taken out from the hook. The structure is simple and easy to install and disassemble;

[0024] (3) Through the setting of the hose, the leaking ground wire can be protected to prevent the hose from being damaged during use. After the early warning control module obtains the result, it will be displayed on the display screen and an alarm sound will be issued through the alarm to achieve the early warning effect;

[0025] (4) By providing a protective plate, a buffer spring and a damper, when an object falls, the protective plate will squeeze the buffer spring, and the buffer spring will cushion the protective plate and the object through its own elasticity, thereby reducing the impact force of the object, thereby protecting the electrical box and preventing the top of the electrical box from being damaged. The damper inside the buffer spring can limit the protective plate to prevent the buffer spring from shaking too much, thereby improving the stability of the device.
