Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering construction, and in particular to dust reduction equipment for municipal engineering construction. Background Art

[0002] Municipal engineering refers to municipal infrastructure construction projects. In my country, municipal infrastructure refers to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (villages), and provide paid or free public products and services to residents based on government responsibilities and obligations. During the construction of existing municipal engineering projects, dust pollution is flying, which makes the construction environment seriously polluted, and then it is easy to be inhaled by construction workers, causing damage to the construction workers. For this reason, it is necessary to use dust reduction equipment to assist in dust reduction operations at the municipal engineering construction site.

[0003] After searching, according to the patent network CN 216259771 U, an adjustable dust suppression equipment for municipal engineering construction relates to the technical field of dust suppression equipment. The adjustable dust suppression equipment for municipal engineering construction includes a movable base, a water tank is fixed on the top of the movable base, a support block is fixed on the right side of the top of the water tank, an atomizing spray barrel is hinged in the support block, a high-pressure water pump is fixed on the top of the water tank, and the high-pressure water pump is connected to the atomizing spray barrel through a hose, a linkage component is arranged inside the movable base, an adjustment component is slidably connected to the bottom of the atomizing spray barrel, and a sealing elastic pipe is fixedly connected to the right side of the inner wall of the movable base. The application controls the atomizing spray barrel to swing up and down in a cycle by moving the movable base and cooperating with the adjustment component through the linkage component, so that the atomized liquid sprayed by the atomizing spray barrel can be sprayed over a wider range, thereby achieving the effect of increasing the spraying area and making the dust suppression effect more comprehensive.

[0004] After searching, according to the patent network CN 215892607 U, a dust reduction and cooling device for municipal engineering construction has been announced, which relates to the technical field of municipal engineering construction equipment. The dust reduction and cooling device for municipal engineering construction comprises a cart, a water tank is installed on one side of the top surface of the cart, and a protective box is installed on one side of the water tank, and a water pump is installed on one side of the top surface of the protective box, and a cooling component is installed on the other side of the top surface of the protective box, and the cooling component comprises an electric telescopic rod and a top plate, a top plate is installed on the top output end of the electric telescopic rod, and an electric turntable is installed on the top surface of the top plate, and a movable seat is installed on the top surface of the electric turntable, a bracket is provided on the top of the movable seat, and limit sleeves are installed on both sides of the top surface of the bracket, and a ground-inserted atomizer is provided in the inner cavity of the limit sleeve. The utility model can effectively cool down and reduce dust in the construction environment, thereby reducing the pollution of the construction environment by flying dust and protecting the safety of construction workers.

[0005] However, although the existing dust reduction equipment can perform good dust reduction operations on construction sites when in use, when the dust removal equipment is used, water can only be sprayed through a single fixed nozzle. The construction workers' hand-held nozzle and the fixed nozzle are not easy to switch between for dust reduction. In addition, when the dust reduction equipment is used daily, the spraying distance of the water mist sprayed from the fixed nozzle is not adjustable through the fan, which reduces the effect of water mist on dust reduction. At the same time, when the fixed nozzle is not in use, the linkage shielding and dust prevention effect of the fixed nozzle is not high, which makes it easy for dust to be adsorbed on the surface of the fixed nozzle and cause nozzle clogging, affecting the subsequent nozzle's dust reduction fluidity, and does not meet people's use needs.
