Description

Technical Field

[0001] The invention relates to the technical field of construction dust reduction, and in particular to a construction dust reduction device for public works. Background Art

[0002] When carrying out municipal public works, there will be a large amount of dust. This dust will float in the air. Construction workers or passers-by will inhale the dust, which will affect their respiratory organs and be detrimental to their health. Dust reduction equipment is generally used to reduce the dust generated by the construction.

[0003] After searching, according to the patent network CN 218553520 U, a construction dust reduction device for municipal public works includes a construction dust reduction device body, a lifting mechanism, a sensing mechanism and a shock absorbing mechanism, the lifting mechanism is located at the top of the construction dust reduction device body, the sensing mechanism is located at the top of the lifting mechanism, and the shock absorbing mechanism is located at the bottom of the construction dust reduction device body, the lifting mechanism includes an electric push rod, a transmission rod, a water pump, a water pipe, a coil, a disc, a water distribution pipe, a spray hole and a water tank, the water tank is fixedly installed inside the construction dust reduction device body, the electric push rod is fixedly installed at the top of the construction dust reduction device body, and the transmission rod is fixedly installed at the transmission end of the electric push rod. The construction dust reduction device for municipal public works is installed with a lifting mechanism, which drives the transmission rod to rise and fall through the electric push rod, the transmission rod drives the disc to rise and fall, and the disc drives the spray hole to rise and fall, so as to facilitate water spraying and dust reduction at different heights.

[0004] After searching, according to the patent network CN213760979U, a dust prevention device with filtering function for municipal public engineering construction is disclosed, including a base, a water tank is arranged at the middle position of one end of the top of the base, water pumps are symmetrically arranged on both sides of the top of the water tank, a liquid guide tube A is arranged at the input end of the water pump, and the other end of the liquid guide tube A extends to the inside of the water tank, and a liquid guide tube B is arranged at the output end of the water pump, and support columns A are symmetrically arranged on both sides of the top of the base; the utility model absorbs external dust through the mutual cooperation of the air intake pipe and the exhaust fan, and filters particulate matter through the filter screen to reduce the amount of dust in the operating environment; through the mutual cooperation of the liquid guide tube A, the water pump, the liquid guide tube B, the exhaust hood, the connecting seat, and the telescopic guide tube, the dust flying in the operating environment is atomized and sprayed with the help of the airflow discharged by the exhaust fan, so as to achieve the effect of dust reduction.

[0005] However, although the existing dust removal devices can be used to adjust and reduce dust generated by construction projects, the dust reduction devices often perform dust reduction operations on the dust through a single dust reduction surface, and the dust reduction effect on the dust on both sides of the dust reduction device is not high. When it is necessary to reduce dust generated by construction projects, the dust reduction direction is fixed, which reduces the effect of adjusting and reducing dust in multiple directions. In addition, when the dust reduction device is used to reduce dust generated by construction projects, the water storage capacity of the water tank is relatively fixed. When dust reduction is performed on different amounts of dust, the water storage capacity of the water tank is fixed, and the operator is required to frequently add water resources, which increases the operator's workload and reduces the dust reduction effect of the dust reduction device on a large amount of dust. This does not meet people's use needs. For this reason, we propose a construction dust reduction device for public works. Summary of the invention
