Description

Technical Field

[0001] The present application belongs to the technical field of industrial dust reduction, and in particular relates to an intelligent green spray dust reduction equipment for construction sites of building projects. Background Art

[0002] During the construction process, a lot of dust is easily generated, which not only affects the health of workers, but also affects the urban air environment. Therefore, dust suppression equipment is often needed to spray water mist on the construction site to achieve the purpose of reducing dust.

[0003] After searching, the patent with announcement number CN116832559B discloses a construction dust reduction device, which sets a limit component, a switching component and two spray mechanisms in multiple spray parts. During the rotation of the spray part around the first reference axis, the limit component is used to switch the spray mechanism between the spray mode and the injection mode, so as to ensure that the dust in the air is wrapped and adsorbed when the spray mechanism is in the spray state, so as to achieve good dust reduction. During the upward rotation of the spray mechanism around the first reference axis, the spray mechanism is switched to the injection mode. When in the injection mode, the columnar water sprayed by the spray mechanism uses the larger water flow rate of the columnar water to reversely flush the spray mechanism when spraying water, so as to avoid the spray mechanism being blocked by dust due to the accumulation of dust, so as to ensure the good working state of the spray mechanism. At the same time, the limit component is used to gradually approach each other during the upward rotation of the spray mechanism around the horizontal axis, so that the water columns sprayed by the spray mechanism can continuously intersect and collide, and then fall under the action of gravity, so that the formed interval can further ensure the dust reduction effect.

[0004] Although the above solution can utilize multiple spraying parts to spray and reduce dust, its spray coverage is small and lacks directionality. It can only perform dust reduction operations in the circular area around the support rod, and the use effect is not good.

[0005] The patent with announcement number CN117582766B discloses a dust suppressor for green building construction. A connecting frame is arranged on the upper part of a mobile trolley, and the support rod is limited by the connecting frame so that the support rod is bent forward in an arc shape, so that the spray assembly can be directly extended to the top of the dust generation, thereby improving the utilization efficiency of the spray water mist, improving the dust suppression effect, and reducing the impact on the workers' bodies; by adjusting the angle of the adjustment seat and the connecting frame, the height and extension distance of the spray assembly can be adjusted, which is convenient and quick to use.

[0006] Although the above scheme can send the spray assembly directly to the top of the dust generation area to carry out targeted dust reduction operations, and can adjust the height of the spray assembly within a certain range, it can actually only achieve close-range spray dust reduction operations. The spray assembly and the support rods used to support the spray assembly are too close to the working area, which may easily interfere with the actions of operating equipment (such as excavators, pile drivers, etc.), and needs to be improved.

Correspondingly, a water tank for storing water and a water pump for delivering water can also be installed on the electric vehicle 1. The inner wall of the air outlet end of the wind tube 11 is hinged with a plurality of atomizing nozzles 17 through a hinge seat. The atomizing nozzles 17 are all connected to the annular water supply pipe 15. A driving mechanism is installed on the outer wall of the air outlet end of the wind tube 11. The atomizing nozzles 17 are all connected to the driving mechanism.

[0048] The present invention adopts the above-mentioned scheme, and the use of the electric trolley 1 makes it easy to move the device within the construction site. By setting the lifting mechanism 2, the height of the wind tube 11 can be adjusted, which is convenient for carrying out targeted dust reduction operations during construction at higher places such as the facade of a building.
