Rapid shooting and collecting device for lightning scene of power transmission channel

Abstract

The invention discloses a rapid shooting and collecting device for a lightning scene of a power transmission channel. The rapid shooting and collecting device comprises a supporting table, fixing claws, a parallel mechanism, an adjusting table and a fixing mechanism, wherein the fixing claws are arranged on the supporting table in the circumferential direction at equal intervals; the adjusting table is installed on the upper end face of the supporting table through the parallel mechanism, and the fixing mechanism is arranged on the adjusting table; and the fixing claws are installed on an electric tower through hooks, and a dome camera is installed on the fixing mechanism. According to the rapid shooting and collecting device, the angle of the adjusting table is adjusted through the parallel mechanism, and therefore the shooting direction of the dome camera is adjusted in an multi-angle mode; the phenomenon that lightning cannot be comprehensively and effectively shot due to the limited shooting angle during shooting with the dome camera is avoided; meanwhile, a rain cover and an arc-shaped water scraping plate are installed on the adjusting table, and play a role in pertection against rain and frog, and therefore the lightning can be shot clearly through the dome camera; and the shooting effect of rapid shooting and collection is improved, and the phenomenon that the shooting effect is poor due to rainwater is avoided.

Description

technical field [0001] The invention relates to the technical field of lightning detection, in particular to a device for quickly photographing and collecting lightning occurrence scenes in a power transmission channel. Background technique [0002] Lightning is the primary cause of power grid failures. In recent years, there have been more special forms of lightning strikes (such as bifurcated lightning, other triggers, and long continuous currents) in areas with dense channels, complex terrain, and intense lightning activities, which cannot pass the traditional lightning strike model. Effective analysis makes prevention and control difficult. At the same time, due to the short time of lightning occurrence, in order to more intuitively and accurately locate the lightning strike point of the line and identify the nature of lightning strike accidents, it is necessary to deploy high-precision lightning scene rapid shooting cameras in key areas to provide for lightning faults. ...

[0002]Lightning is the primary cause of power grid failures. In recent years, there have been more special forms of lightning strikes in areas with dense channels, complex terrain, and intense lightning activities (such as bifurcated lightning, other trigger type, long continuous current), which cannot be effectively analyzed by the traditional lightning strike model, resulting in difficulty in prevention and control. At the same time, because the lightning occurrence time is short, in order to more intuitively and accurately locate the lightning strike point of the line and identify the nature of the lightning strike accident, it is necessary to Deploy high-precision fast shooting cameras for lightning occurrence scenes in key areas to provide intuitive image and video observations for lightning fault analysis and prevention measures. However, fast shooting cameras for lightning occurrence scenes need to be installed at high altitudes to shoot lightning, but rapid The following problems will occur during the installation and shooting of the shooting camera:

[0003]1. Most of the fast shooting cameras are installed on one side of the high-altitude electric tower, and the installation position is fixed, which leads to certain restrictions on the shooting angle of the fast shooting camera Restrictions, fast shooting cameras cannot fully and effectively shoot lightning;

[0004]2. The occurrence of thunder and lightning is often accompanied by rainwater. After the rain falls on the lens of the fast shooting camera, the image captured by the fast shooting camera is blurred, resulting in rapid The shooting effect of the shooting collection is poor
