[0002] With the development of society, people's environmental awareness is getting stronger and stronger, making the environmental protection standards of various industries more and more stringent. For example, in the process of civil construction of construction projects, in order to avoid environmental pollution caused by dust, dust removal equipment is usually installed at the civil construction site to reduce the dust at the construction site.

[0003] The existing document with publication number CN220878255U discloses a dust removal device for civil construction of buildings, including a base plate and a cover plate, wherein an angle adjustment component and a dust removal component are arranged on the top of the base plate; the dust removal component comprises a water tank and a water pump fixedly installed inside a spray box, wherein the water tank is connected to the water pump, an atomizing nozzle is fixedly installed on the top of the water spray pipe, dust suction fans are fixedly installed on the front and back of the dust suction box, three sets of guide rails are fixedly installed inside the dust suction box, and a filter plate is slidably connected to the inner side of the guide rail;

[0004] However, it still has the following disadvantages in actual use:

However, during use, it is impossible to detect whether there are construction workers in the direction of water mist spraying, resulting in the water mist being easily sprayed on the construction workers, and its intelligence level is low;
