Problems solved by technology

This will bring about two major problems: 1) Due to the large amount of water absorption, the water will take a long time to dry or evaporate, and the microphone will be covered for a long time to work in a high-humidity environment, which will be easily damaged or its life will be shortened; 2) due to the sponge Water absorption hinders the sound transmission performance, so the data measured before the sponge absorbs water is not evaporated is accurate, and the measurement can only be stopped or treated as invalid data, which reduces the effective measurement time and affects the integrity of the data. Assessment indicators affecting the percentage of effective data in online monitoring
Such a design may bring hidden dangers to the safety of the microphone

Embodiment 1

[0045] As an embodiment of the novel all-weather outdoor microphone system of the present invention, as figure 1 and figure 2 As shown, it includes a net cover 1 and a lower net cover 2, the net cover 1 and the lower net cover 2 are fixedly connected by a net cover fixing part 3, and the net cover 1 is provided with an insulating lightning protection and anti-bird stop needle 4. The insulating lightning-proof bird-stop pin 4 has a waterproof structure, the net cover 1 and the insulating lightning-proof bird-stop pin 4 are connected through an insulating lightning-proof fixing component 5, and the insulating lightning-proof fixing component 5 is located on the net The top outside the cover 1, the lower mesh cover 2 is provided with a support rod body 6, and the support rod body 6 and the lower mesh cover 2 are fixedly connected by a waterproof non-slip fixing member 7, and the support rod body 6 Placed at the lower end of the lower net cover 2, the lower end of the support ro...

Embodiment 2

[0056] As an embodiment of the new all-weather outdoor microphone system of the present invention, the difference from Embodiment 1 is that in this embodiment, the inner nets of the net cover 1 and the lower net cover 2 can be selected with good weather resistance and have The non-metallic braided mesh of water characteristics can place the small acoustic calibration sound generator in the main rod 29, and use a thinner acoustic conduit to transmit the sound to the acoustic calibration coupling cavity 9 to further reduce the acoustic calibration coupling cavity 9. The structural size is more conducive to the needs of acoustic measurement in the 0° direction. The two-way limit electric telescopic rod mechanism 25 can be replaced by a pneumatic telescopic rod mechanism. The sound-transmitting tapered guide surface 10 can use 3 to 6 metal wires. Make the front of the tapered guide to further improve the sound transmission performance of the front of the guide. An electric heating ...

Embodiment 3

[0059] As an embodiment of the new all-weather outdoor microphone system of the present invention, the difference from Embodiment 1 is that in this embodiment, the inner nets of the net cover 1 and the lower net cover 2 can be selected with a slightly lower density, and sprayed with The metal braided mesh of the water-based paint, the two-way limiting electric telescopic rod mechanism 25 can be replaced by a hydraulic telescopic rod mechanism.

[0060] In this embodiment, other structures and beneficial effects are consistent with those in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of sound measuring devices, and particularly relates to a novel all-weather outdoor microphone system. The novel all-weather outdoor microphone system comprises a metal perforated plate, an upper screen and a lower screen, wherein the upper screen and the lower screen are combined with a metal mesh. The upper screen and the lower screen are fixedly connected though a screen fixation part. An insulation lightning protection bird-proof stop needle is arranged on the upper screen. The upper screen is connected with the insulation lightning bird-proof stop needle through an insulation lightning protection fixing assembly. The insulation lightning protection fixing assembly is located at the top of the outside upper screen. A support rod body is arranged on the lower screen. The support rod body is fixedly connected with the lower screen through a waterproof anti-slip fixation part. The support rod body is arranged on the lower end of the lower screen. A moving device with a preload mechanism is arranged in the support rod body. An external power supply mechanism is arranged on the lower end of the support rod body. The support rod body is fixedly connected with the external power supply mechanism.

Description

technical field [0001] The invention relates to the technical field of sound measuring equipment, in particular to a novel all-weather outdoor microphone system. Background technique [0002] With the development and progress of society, social noise such as ground transportation, underground transportation, air transportation, commercial activities, and construction sites are increasingly harmful to the crowd, and environmental protection monitoring agencies are also constantly strengthening the monitoring of social noise. In particular, equipment such as outdoor noise monitoring stations and mobile noise monitoring vehicles are becoming more and more popular. It provides a strong guarantee for continuous all-weather monitoring of noise data in noise-sensitive areas, and provides comprehensive and objective reference data for subsequent relevant departments to prevent and control noise hazards and carry out urban planning. [0003] For noise detection equipment, the most v...
