Description

Technical Field

[0001] The utility model relates to the technical field of spraying dust reduction, and more specifically to a construction site spraying dust reduction device. Background Art

[0002] Spray dust suppression refers to a method of suppressing and capturing dust by dispersing water into mist droplets and spraying them toward the dust source. Spray dust suppression can be carried out through a variety of equipment. In construction, a spray dust suppression equipment that construction workers often use is a fog cannon.

[0003] The mist cannon spreads water mist by arranging a water mist nozzle on one side of a pipe body that can blow out high-speed airflow. However, the nozzles equipped with existing mist cannons are mostly exposed to the outside and lack protective measures. When the mist cannon is not in use, due to the large amount of dust and impurities in the air at the construction site, the nozzles are more likely to accumulate dust when idle, causing the nozzles to be blocked, affecting the use effect of the mist cannon. Therefore, it is urgent to design a construction site spray dust reduction device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a construction site spray dust reduction device to solve the problem that the nozzles equipped with the existing fog cannons in the above-mentioned background technology lack protective measures and are more likely to accumulate dust when idle, causing nozzle clogging.

[0005] The utility model provides the following technical solutions: a construction site spray dust suppression device, including a through pipe, and also including a spray component, a fixed protection component, a rotating protection component, and a linkage component. The spray component is fixedly installed on one side of the through pipe, the fixed protection component is fixedly installed in the spray component, the rotating protection component is rotatably installed on one side of the fixed protection component, the linkage component is rotatably installed in the fixed protection component, the rotating protection component is fixedly connected to the linkage component, a fan is provided in the through pipe, and the linkage component can drive the rotating protection component to rotate when the fan is started.

[0006] Furthermore, the spray assembly includes a mounting ring, a water pipe, and a plurality of nozzles. The mounting ring is fixedly mounted on one side of the through pipe, the water pipe is fixedly mounted on an inner wall of one side of the mounting ring, and the plurality of nozzles are equidistantly distributed on the outer wall of the water pipe.

[0007] Furthermore, the fixed protective assembly includes a fixed protective sleeve and several through holes. The fixed protective sleeve is fixedly installed on the inner wall of one side of the mounting ring. The fixed protective sleeve is adapted to the water pipe. Several through holes are equidistantly arranged on one side of the fixed protective sleeve, and the through holes correspond to the nozzle.

[0008] Furthermore, the rotation protection assembly includes an annular plate and a plurality of baffles. The annular plate is rotatably mounted on one side of the fixed protection sleeve. The plurality of baffles are equidistantly distributed on the outer wall of the annular plate. The baffles are adapted to the through holes.

[0009] Furthermore, the fixed protection component also includes two arc grooves, which are equidistantly arranged on one side of the fixed protection sleeve. The rotating protection component also includes two sliders and two springs. The two sliders are equidistantly distributed on the side where the annular sheet and the fixed protection sleeve fit together. The two springs are respectively fixedly installed at one end of the two sliders, and the two sliders are respectively slidably installed in the two arc grooves, and the two springs are respectively fixedly connected to the two arc grooves.

[0010] Furthermore, the linkage assembly includes a rotating ring and a plurality of blades. The rotating ring is rotatably mounted on the inner wall of the fixed protective sleeve. The plurality of blades are equidistantly distributed on the inner wall of the rotating ring. The annular sheet is fixedly sleeved on the outer wall of the rotating ring.

[0013] Technical effects and advantages of the utility model:

[0014] The utility model starts the fan to blow out high-speed airflow from the through pipe when spraying and reducing dust, and passes water into the water pipe to spray. When the high-speed airflow blows out from one side of the through pipe, it will blow a plurality of blades to rotate counterclockwise, thereby driving the rotating ring and the annular sheet to rotate counterclockwise. The rotation of the annular sheet will drive the two sliders to slide counterclockwise in the two slide grooves and compress the two springs. When the two springs are compressed to the ends, a plurality of baffles will be driven to be offset from a plurality of through holes, thereby opening the through holes. At this time, water mist can be sprayed out from the through holes to spray and reduce dust. After the spraying and reducing dust is completed, the fan is turned off. At this time, when the high-speed airflow in the through pipe is small, after several blades lose the push of airflow, the two springs will be released, pushing the two sliders to reset, and then driving the annular sheet and several baffles to reset, blocking the through hole again, and the fixed protective sleeve can be closed to protect the nozzle, reduce its contact with dust and impurities, and prevent blockage. Through the set fixed protection component and rotating protection component, the baffle can be automatically opened during spraying and dust reduction to enable the spraying and dust reduction to proceed normally. After the spraying and dust reduction is completed, the baffle can automatically reset to protect the nozzle, reducing the possibility of blockage due to the accumulation of dust and impurities in the nozzle.
