Lightning protection detection device for constructional engineering

Abstract

The invention relates to the technical field of lightning protection detection, in particular to a lightning protection detection device for constructional engineering. The device comprises a base with an upward opening, a supporting mechanism for supporting the base is arranged at the bottom of the base, the base is annular and hollow, a rotating ring is rotatably connected to the top surface of the base, and a supporting cylinder is fixed to the top surface of the rotating ring. A supporting plate is arranged above the supporting cylinder, a detector is fixedly mounted at the top of the supporting plate, a telescopic mechanism is arranged in the supporting cylinder and used for adjusting the height of the supporting plate, and a motor is fixed in the supporting cylinder. According to the scheme, the detector moves around a lightning current carrier along with the supporting cylinder, detection on the periphery of the lightning current carrier is facilitated, the height of the supporting plate is adjusted through the telescopic mechanism, the detection range of the detection equipment is further enlarged, multi-directional detection on the lightning current carrier is facilitated, and errors of detection results are reduced.

Description

technical field [0001] The invention relates to the field of lightning protection detection, in particular to a lightning protection detection device for construction engineering. Background technique [0002] The basic principle of the magnetic tape type lightning current recorder is: use a high-sensitivity recording tape to process the pre-recorded reference signal, place it near the lightning protection device, and under the action of the magnetic field of the lightning current, a certain length of pre-recorded data on the tape will be eliminated. The reference signal above, its cancellation length is proportional to the measured lightning current amplitude. Therefore, by detecting the erasing length of the pre-recorded reference signal and analyzing and processing the data by the single-chip microcomputer, the magnitude of the measured lightning current amplitude can be determined and displayed.

Problems solved by technology

[0004] Under the action of lightning, the lightning protection equipment will be partially damaged. Therefore, testing equipment is needed to detect the lightning strike degree of the equipment. Most of the lightning protection detection and recording devices in the prior art are simply fixed near the lightning protection equipment. When testing, only It can detect and record the lightning current in a single direction or a single position, but cannot detect the surroundings of the lightning protection equipment in real time, resulting in deviations in the detection results. In view of this, we propose a lightning protection detection device for construction engineering
