Noise monitoring device of high-voltage alternating-current electric transmission line

Abstract

The invention relates to a noise monitoring device of a high-voltage alternating-current electric transmission line. The noise monitoring device comprises a main support body, a noise detection probe,a control display panel and a monitoring controller, wherein the noise detection probe, the control display panel and the monitoring controller are arranged on the main support body; the main supportbody comprises a tripod body and a supporting column which is arranged at the upper end of the tripod body, the control display panel is arranged on the side face of the supporting column, a horizontal layer board is arranged at the upper end of the supporting column, and a telescopic probe support is rotatably connected onto the horizontal layer board; a probe fixator is arranged on the end portion of the probe support, the noise detection probe is arranged on the probe fixator, and the tripod body comprises a connection disk and three supporting leg pipes, wherein the supporting leg pipes are connected with the connection disk; supporting feet are arranged at the lower ends of all the supporting leg pipes, foot nails are arranged at the bottoms of the supporting feet, a telescopic fixing rod is arranged at the lower end of the connection disk, and a flying ring is arranged at the lower end of the telescopic fixing rod. Compared with the prior art, the supporting feet are arranged atthe lower ends of the supporting leg pipes, when the noise monitoring device is fixed outdoors, the main support body can be fixed onto the ground through the foot nails at the lower ends of the supporting feet, and thus the noise monitoring device is more stable.

Description

Technical field [0001] The invention relates to the technical field of noise monitoring, and in particular to a noise monitoring device for high-voltage AC transmission lines. Background technique [0002] The environmental impacts of high-voltage transmission lines include construction noise during the construction period, domestic sewage from construction workers, and the impact of construction dust on the surrounding environment. [0003] In the process of detecting the noise of high-voltage transmission lines with a noise detector, if the inspector holds the noise detector for a long time, the inspector needs to hold the instrument’s hand to maintain a certain height and direction, which will cause low work efficiency and impair the detection. The operation requirements of personnel are relatively high. If the noise monitor is fixed on the existing bracket, the stability is poor in the case of strong wind. Summary of the invention [0004] The purpose of the present invention i...
