Outdoor lightning spectrum observation room

Abstract

The invention discloses an outdoor lightning spectrum observation room. The room comprises an observation room base, an observation room main body in a hexagonal prism shape is installed on the observation room base, an observation room top cover is arranged at the top of the observation room main body, and a lightning rod is arranged at the top of the observation room top cover; the observation room main body is formed by inlaying six panels with lightning and rain protection functions in sequence, and a leak-proof sealing strip is installed at the junction of each two adjacent panels; an observation room door capable of closing automatically is arranged on one of the panels, magnetic sealing strips are embedded around the observation room door and around a door frame of the observation room door, a pull ring is arranged on each panel, an observation window opening is arranged on each panel, and when the observation is carried out in raining days, an observation window made of water repelling glass is embedded in the observation window opening. According to the observation room, lightning occurring in any direction can be observed, the problem of limited shooting azimuth in a lightning spectrum observation experiment is solved, and the observation efficiency is improved; through the arrangement of the observation window made of the water repelling glass, and the influence of rainwater attached to the observation window on a spectrum observation effect is reduced to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of lightning observation and relates to an outdoor lightning spectrum observation room. Background technique [0002] Lightning spectrum observation can record the emission spectrum of the lightning channel, analyze the spectral radiation characteristics of different stages of lightning, and is also the only means to obtain the internal characteristic parameters and microscopic physical processes of the discharge channel. Based on the spectral data, according to the theory of plasma spectroscopy and atomic structure, physical parameters such as electron temperature, electron density and electrical conductivity inside the discharge channel can be quantitatively calculated to provide information for revealing the microscopic physical mechanism inside the channel. The slitless spectrograph used for lightning spectrum observation consists of a high-speed camera as a recording system and a planar transmission gra...

AI Technical Summary

Problems solved by technology

Lightning is often accompanied by wind and rain. In order to prevent rain and lightning, lightning spectrum observation tests can only be carried out indoors.

When observing the lightning spectrum indoors, the lens of the high-speed camera must face the window of the room, so there are several unavoidable problems in the observation process: First, the location where the lightning occurs is arbitrary, and some locations will be affected by the windows during observation. Due to the limitation of orientation, it is impossible to observe normally, which reduces the chance of lightning spectrum observation, resulting in low observation efficiency

Secondly, if there is heavy wind and rain during observation, in order to avoid damage to the high-speed camera due to rain, the window must be closed to shoot. The rain attached to the window glass has a great impact on the observation effect, and even the spectral data cannot be clearly recorded.
