Problems solved by technology

Therefore, the anti-loosening measures of thread fixing glue cannot be used during the installation process, and the fasteners connected by threads have the risk of failure in the long-term vibration environment
The weight of some monitoring terminals is greater than 5kg. If the terminal falls from a high altitude, it will cause serious injury to people, vehicles, buildings, etc. on the ground area of ​​the transmission line.

Embodiment 1

[0062] An embodiment of the present invention provides a safe anti-dropping transmission line monitoring terminal, wherein the upper shell assembly 01 and the lower shell assembly 12 are connected at one side by a hinge 04 . When installing on the transmission line, rotate the upper shell assembly 01, close it with the lower shell assembly 12 to hold the wire tightly, and cooperate with the clamp 23 and the double rack hook assembly 09 to initially lock the upper shell assembly 01 and the lower shell assembly 12. Tighten; then use the lever to turn the clip 23 embedded in the lower shell assembly, increase the matching depth of the clip and the double rack hook assembly 09, lock the upper shell assembly and the lower shell assembly on the transmission line, and prevent the terminal from being disconnected from the transmission line. fall off.

[0063] Specifically, such as figure 1 As shown, the safe anti-dropping transmission line monitoring terminal includes:

[0064] Uppe...

Embodiment 2

[0083] An embodiment of the present invention provides a safe anti-dropping transmission line monitoring terminal, wherein the upper shell assembly 01 and the lower shell assembly 12 are connected at one side by a hinge 04 . When installing on the transmission line, rotate the upper shell assembly 01, close it with the lower shell assembly 12 to hold the wire tightly, and cooperate with the clamp assembly and the double rack hook assembly to initially lock the upper shell assembly 01 and the lower shell assembly 12 ; Turn the hoop embedded in the lower shell assembly through the lever, increase the matching depth of the hoop assembly and the double rack hook assembly, and lock the upper shell assembly and the lower shell assembly on the transmission line; then set the safety lock on the locked state, when the locking mechanism fails, the safety lock cooperates with the hinge 04 to connect the upper shell assembly and the lower shell assembly of the terminal to prevent the termi...

Embodiment 3

[0092] Since there is a gap between the cooperation of the hinge 04 and the cooperation of the hook 51, when switching to the connection state of the safety lock assembly 07, the cooperation gap between the upper and lower magnetic conductors of the energy-taking coil will increase. The impact of tight mode changes, to ensure the normal operation of the terminal energy harvesting module.

Abstract

The invention discloses a safe anti-falling power transmission line monitoring terminal, which comprises an upper shell assembly, a hoop assembly, a lower shell assembly, a fixed hook and a double-rack hook assembly, the hoop assembly is arranged on the upper shell assembly; the lower shell assembly is connected with the upper shell assembly through a hinge, and the lower shell assembly is provided with an arc-shaped boss used for pressing a power transmission line. The fixed hook is arranged on one side, provided with the hinge, of the lower shell assembly; the double-rack hook assembly is arranged on the side, away from the hinge, of the lower shell assembly, the double-rack hook assembly and the fixing hook are clamped to the corresponding positions of the hoop assembly respectively, and therefore the power transmission line monitoring terminal can be locked to a power transmission line. Threaded connection is canceled, and the situation that the terminal is loosened due to the factthat locking connection of the power transmission line monitoring terminal is damaged by vibration is prevented; and furthermore, a safety lock assembly is arranged on the terminal, so that the riskthat the terminal falls off from the power transmission line can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of power transmission line monitoring, and in particular relates to a safe and anti-dropping power transmission line monitoring terminal. Background technique [0002] The transmission line monitoring terminal usually adopts the upper and lower split forms, and the upper and lower parts are locked on the transmission line with screws or bolts during on-site installation. On the AC transmission line, the terminal senses and obtains electric energy on the transmission line through the energy harvesting CT, and monitors the operation of the transmission line and the state of the surrounding environment. In order to be installed on the power transmission line, the magnetizer of the energy-taking coil is divided into upper and lower parts; due to the existence of the gap between the magnetizers, the energy-taking coil will generate alternating electromagnetic force during operation, and the electromagnetic force ...
