Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

Example

As shown in FIG. 1 , a high-voltage AC transmission line noise monitoring device includes a bracket body, a noise detection probe 15 disposed on the bracket body, a control display panel 12 , a monitoring controller and an alarm 16 . The bracket main body includes a tripod body and a support column 1 arranged at the upper end of the tripod body, and a horizontal supporting plate 10 is provided at the upper end of the support column 1 . A telescopic probe holder 11 is rotatably connected to the horizontal pallet 10, and the probe holder 11 is arranged obliquely above the horizontal pallet 10. The end of the probe holder 11 is provided with a probe holder 18, and the noise detection probe 15 is arranged on the probe holder 18. superior. The control display panel 12 is arranged on the side of the support column 1, and the control display panel 12 is provided with an LCD display screen and several control keys. The monitoring controller is arranged in the support column 1, and the monitoring controller includes a main control board, a power adapter and a noise meter connected with the main control board, and the main control board is connected with a control display panel 12 and an alarm 16. The alarm 16 includes a warning light, which is arranged on the horizontal support plate 10. The alarm 16 is controlled by setting the noise alarm threshold. When the acquisition parameter reaches the set threshold, the warning light is on until the noise returns to the normal required range value. A spirit level 19 is arranged on the horizontal pallet plate.

The probe bracket 11 is a telescopic sleeve, and the connecting end between the probe bracket 11 and the horizontal supporting plate 10 is provided with a 360-degree rotating connecting piece 13 and a positioning locking piece 14 . A clamping positioning structure 17 is arranged between the sleeve pipe of the probe holder 11 and the sleeve pipe. When the probe holder 11 needs to be extended, the sleeve pipe and the sleeve pipe can be fixed to realize the elongation function. When the probe holder 11 needs to be Mutual socketing between sleeves can be realized during shrinkage.
