Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in construction engineering, specifically a dust removal device for construction projects. Background Technology

[0002] Engineering construction refers to the new construction, expansion, and renovation of projects such as building construction, pipeline and equipment installation, and building decoration and renovation. It is the basic production process that forms fixed assets and the general term for other related construction work. Dust comes from industrial emissions, combustion smoke, soil dust, etc. Dust is a major enemy of human health. It carries many bacteria, viruses, and insect eggs and flies everywhere, spreading diseases. A lot of dust is also generated during the construction process at some construction sites, which poses many hazards to construction workers.

[0003] Currently, most dust control methods in construction projects rely on sprayers to settle dust. However, over time, dust can accumulate at the atomizing nozzles, causing blockages and affecting dust control efficiency. Traditional methods of cleaning clogged nozzles involve replacing them, which is inconvenient for the spray system, and replaced nozzles are typically discarded, increasing costs. Existing spray systems also lack the ability to adjust the spray area, and traditional manual adjustments are slow and inconsistent. Therefore, we offer a dust control system for construction projects that solves these problems. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dust removal device for construction projects.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for construction projects, comprising a protective cover, connecting plates fixedly connected to the left and right side walls of the protective cover, a bearing plate fixedly connected to the inner wall of the protective cover, a sleeve fixedly connected to the front end of the bearing plate, a spray pipe disposed inside the sleeve, a connecting pipe extending through the bottom end of the spray pipe, an adjustment mechanism disposed on the outer wall of the spray pipe below the sleeve, a cleaning mechanism disposed on the outer wall of the sleeve above the bearing plate, a cover plate rotatably connected to the top of the rear end of the protective cover above the cleaning mechanism, and a power mechanism disposed on the top wall of the bearing plate near the cleaning mechanism.

[0008] Furthermore, the connecting plates are located at the four corners of the protective cover, and bolt holes for connection with external fixing mechanisms are provided inside the connecting plates.

[0009] Furthermore, the outer wall of the spray pipe is rotatably connected to the inner wall of the sleeve, the spray pipe is L-shaped, and the connecting pipe is connected to the external water supply mechanism.

[0010] Furthermore, the adjustment mechanism includes an adjustment wheel, which is fixedly connected to the outer wall of the spray pipe. A power wheel is engaged on the right side of the adjustment wheel. The bottom wall of the support plate is rotatably connected to the top of the power wheel through a fixed frame. A toothed belt is engaged on the top of the power wheel. A servo motor is engaged inside the toothed belt on the right side of the power wheel. The outer wall of the servo motor is fixedly connected to the bottom wall of the support frame through a bracket.

[0011] Furthermore, the cleaning mechanism includes a movable frame. The outer wall of the sleeve is rotatably connected to the front end of the movable frame via a rotating rod. A contact rod is fixedly connected to the top of the movable frame located on the right side of the sleeve. The bottom wall of the movable frame and the top wall of the bearing plate are on the same horizontal plane. A power motor is fixedly connected inside the top of the movable frame. A cleaning wheel is fixedly connected to the top output end of the power motor. A top rod is fixedly connected to the top of the movable frame.

[0012] Furthermore, the bottom wall of the cover plate contacts the top wall of the top rod, and a torsion spring is provided at the rotatable connection between the cover plate and the protective cover.

[0013] Furthermore, the power mechanism includes a push block, the front end of which is set at an inclined angle, the side wall of the push block and the outer wall of the contact rod are slidably connected, and an electro-hydraulic rod is fixedly connected to the rear end of the push block, which is fixedly connected to the top wall of the bearing plate.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, the dust removal device for construction projects has the following advantages:

[0016] I. This utility model uses an electric hydraulic rod to drive a push block to move. The push block drives a moving frame to rotate via a contact rod. The moving frame drives a top rod to open the cover plate. The moving frame drives a power motor to move towards the head of the spray pipe. The power motor drives a cleaning wheel to clean the head of the spray pipe. This solves the problem that the traditional method of cleaning clogged spray heads involves replacing the spray head, which increases costs and is cumbersome. It has the advantage of automatically cleaning spray heads.

[0017] II. This utility model uses a servo motor to drive a toothed belt to rotate, which in turn drives a power wheel to rotate. Each rotation of the power wheel causes the adjusting wheel to rotate 60 degrees. After the adjusting wheel rotates 180 degrees, the servo motor stops running. At this time, the adjusting wheel drives the spray pipe to rotate 180 degrees, and the head of the spray pipe moves towards the cleaning mechanism. This solves the problem that existing spraying devices require manual adjustment to adjust the spraying area, resulting in slow speed and inconsistent performance. It has the advantage of automatic adjustment. Attached Figure Description
