Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a dust suppression device for steel structure construction. Background Art

[0002] Steel structure refers to a structural form that can bear and transfer loads and is made of steel plates and hot-rolled, cold-bent or welded profiles connected by connectors. The steel structure system has comprehensive advantages such as light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it has unique advantages in the three aspects of "high, large, and light". Globally, especially in developed countries and regions, steel structures are reasonably and widely used in the field of construction engineering. During the construction of steel structures, a large amount of dust will be generated, making the construction site look "smoky and foul", causing great trouble to workers and passers-by. At this time, the dust suppression device plays an important role. The dust suppression device can quickly reduce dust on the construction site.

[0004] However, the above patent still has certain disadvantages when in use: although it can absorb and remove the surrounding dust through the water sprayed by the high-pressure nozzle, the sprayed water will not act on the dust 100%. At this time, the dust and excess water will fall directly to the ground, which is easy to cause water accumulation and pollution on the ground, thereby greatly reducing the cleanliness of the construction site. In addition, the water supply of the device mostly depends on the water supply of the municipal pipeline, and the flexibility of the water supply is not very good, which reduces the practicality of the device.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0039] Working principle: During actual use, personnel can use the lockable moving wheels 15 to move the dust reduction cylinder 1 as a whole to the site area of ​​the steel structure construction, and then adjust the ejection height of the hydraulic rod 6 according to the different dust reduction heights required. Then, after being lifted to the corresponding position, the atomized water sprayed by the dust reduction nozzle 4 can adsorb and settle the surrounding dust, and before the dust reduction nozzle 4 sprays water, the electric push rod 26 inside the lower water guide chamber 13 can push the connected expansion plate 20 outward.

At this time, the formed collection area can carry out a certain amount of treatment on these substances. The collecting operation can avoid the pollution and water accumulation caused by falling to the ground. The collected materials can slide into the lower water guide cavity 13 due to the inclined setting of the water guide cloth 22 and the drainage hole 21 inside the expansion plate 20. The collected materials fall from the circulation groove 23 and enter the sewage bucket 16. The sewage and dust are filtered and processed by the internal filter element 19 and the activated carbon layer 17. The purified sewage can be convenient for subsequent secondary utilization operations. At the same time, when the device is idle, the humidity sensor 8 and the rain sensor on the top can detect the surrounding environmental rainfall. When the rainfall is detected to meet the standard, the structure inside the upper water guide cavity 9 will be the same as that of the lower water guide cavity 13, and then the rainwater will be filtered and collected in the water storage tank 12, which is convenient for subsequent use, enriching the water supply source of the device, improving the overall practicability of the device, and facilitating better use. The device as a whole has the advantages of strong practicability, rainwater collection, dust reduction and excess water collection.
