Description

Technical Field

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. During the construction of highway engineering, some illegal buildings need to be demolished. A large amount of dust will be generated during the demolition process, and a dust reduction device is needed to carry out dust reduction operations. The water is extracted and concentrated through the internal booster pump to form a water column, which is then sprayed out from the barrel. The water in the water column absorbs dust and impurities in the air and finally achieves the effect of dust reduction.

[0003] According to a Chinese patent with the announcement number "CN217163694U", a dust suppression device for highway engineering construction is disclosed, including a bottom plate, a support plate is fixedly connected to the top of the bottom plate, a first bracket is fixedly installed at the bottom of the right side of the support plate, a second bracket is fixedly installed at the top of the right side of the support plate, a motor is arranged on the top of the first bracket, a rotating block is fixedly connected to the output end of the motor, a linkage rod is fixedly connected to the bottom of the right side of the rotating block, a support plate is arranged on the top of the second bracket, a rotating shaft is fixedly connected to the bottom of the support plate, the rotating shaft is rotatably connected to the top of the second bracket, and an arc plate is fixedly connected to the bottom of the right side of the support plate.
