Negative pressure suction type dust fall road barrier

Abstract

The invention discloses a negative pressure suction type dust fall road barrier which comprises a unit body. The unit body is provided with a transmission cavity, a driving cavity and a water storagecavity from top to bottom in sequence, and a water injection hole communicated with the water storage cavity is formed in the unit body. The barrier has the advantages that by means of the airflow effect generated by the rapid passage of vehicles, a wind wheel is driven to rotate circumferentially and quickly, and an a rotating plate coaxially arranged with the wind wheel rotates synchronously; byconverting repellence of an active magnet and a driven magnet and the elastic force of a reset spring into left and right linear motion of an air-tight piston, by means of a one-way air extraction channel, the dust fall channel is in a negative pressure state, by means of a one-way inflatable channel, a booster cavity is in a position pressure state, the dust fall channel under the negative pressure state forms pumping action on external dusty gas, the booster cavity under the positive pressure state performs atomization on water through a three-prong spray channel, the contact area between the dust and the water is expanded, the dust fall effect is improved, air pollution is reduced, and the pedestrian health is protected.

Description

technical field [0001] The invention relates to the technical field of transportation facilities, in particular to a negative pressure suction type dust suppression road isolation pier. Background technique [0002] The isolation pier is a kind of roadway isolation facility, which is used to separate the traffic flow traveling in the opposite direction or in the same direction, and has the function of prohibiting vehicles from turning left to drive in and out and pedestrians crossing the road at will. It is generally set on the center line of the road or the lane on the divider. [0003] The isolation pier in the prior art usually only plays a single isolation role. When the weather is dry and the air contains a large amount of dust, due to the fast speed of vehicles traveling in the forward and reverse lanes, the dust is easy to rise, which pollutes the environment very much. It is inhaled into the lungs and seriously affects the health of pedestrians. [0004] In order t...
