Traffic guidance sentry box capable of automatically reducing noise and reducing dust

Abstract

The invention belongs to the field of traffic facilities, and particularly relates to a traffic guidance sentry box capable of automatically reducing noise and reducing dust. The traffic guidance sentry box comprises a circular base, wherein the circular base is fixedly connected with the ground, and a hollow supporting rod is fixedly connected to the ground; a circular baffle is fixedly connectedto the hollow supporting rod, and a plurality of sound absorption cavities are formed in the circular baffle and are annularly distributed, and vibrating pieces are rotationally connected in the sound absorption cavities; piezoelectric ceramic pieces are embedded in the vibrating pieces, and a first cavity is formed in the circular base; and a plurality of air holes communicating with the first cavity are formed in the circular base, and the air holes correspond to the sound absorption cavities one to one. According to the traffic guidance sentry box, noise can be recycled, and an external power supply is not needed, so that the cost is saved; and dust flying around the sentry box can be eliminated while noise reduction is carried out, and a comfortable working environment is provided fortraffic police who direct traffic.

Description

technical field [0001] The invention belongs to the field of public transport facilities, in particular to a traffic command booth capable of automatically reducing noise and dust. Background technique [0002] The traffic command booth refers to the booth used to guide the road traffic. The traffic booth is generally designed as an open booth for one person to stand. During the day, the traffic police can stand in it and direct the traffic with gestures to ensure the smoothness of the road and avoid Road congestion occurs. [0003] The traffic command box is generally set in the center of the road, and because there are many vehicles on the road, it is easy to raise dust on the road surface and fill the traffic command box. The traffic police stay in the post for a long time, and it is very easy to absorb a large amount of dust. The dust can It directly enters and adheres to the human respiratory tract and alveoli, causing respiratory diseases. In addition, because there a...

[0003] The traffic command box is generally set in the center of the road, and because there are many vehicles on the road, it is easy to raise dust on the road surface and fill the traffic command box. The traffic police stay in the post for a long time, and it is very easy to absorb a large amount of dust. The dust can It directly enters and adheres to the human respiratory tract and alveoli, causing respiratory diseases. In addition, because there are many vehicles on the road, there will be a lot of noise around the sentry box. Being in the noise for a long time will affect the hearing of the traffic police, and the noise will make People feel irritable, which is not conducive to directing traffic
