[0002] Concrete components refer to concrete components, which are made of cement, sand, aggregate (usually crushed stone or crushed stone) and water mixed in a certain proportion. They are used in the energy dissipation and anti-collision area of ​​hydropower stations. They have the characteristics of good durability, low construction cost, and strong plasticity. The repair of defects in concrete components is to chisel the defective parts, and then re-pour concrete on the chiseled parts. When chiseling, the larger debris produced by chiseling can be removed by sweeping, but a large amount of dust produced by chiseling will remain on the surface of the repaired part. As a result, after re-pour of concrete, the bonding strength of the bonding surface between the new and old concrete is low, and cracks and falling off are prone to occur, affecting the quality of the repair project. In view of this, the utility model proposes a dust cleaning machine for repairing concrete components in anti-collision areas. Utility Model Content

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, the utility model proposes a dust cleaning machine for repairing concrete components in an anti-collision area, comprising an L-shaped mounting plate 1 and a handle 11 mounted on one side thereof, the handle 11 being arranged for easy gripping. It also comprises a cleaning mechanism 2 mounted on the mounting plate 1 for sweeping dust, the cleaning mechanism 2 comprising a servo motor 21, a transmission shaft 22, a cleaning column 23, and bristles 24. The servo motor 21 is mounted on the side of the mounting plate 1, the output end of the servo motor 21 passes through the mounting plate 1 and is fixedly connected to the transmission shaft 22, and the servo motor 21 drives the transmission shaft 22 to rotate after starting. The cleaning column 23 is mounted on one end of the transmission shaft 22 away from the servo motor 21, and the transmission shaft 22 drives the cleaning column 23 to rotate when rotating. Multiple groups of bristles 24 are distributed in a circular array on the outside of the cleaning column 23, and the cleaning column 23 drives the bristles 24 to rotate when rotating, and at the same time cleans the dust, so that the dust attached to the repaired part is diffused in the air.

[0032] For details, please refer to Figure 2-5The dust cleaning machine also includes a dust collecting assembly 3 arranged in the cleaning mechanism 2 for absorbing dust. The dust collecting assembly 3 includes a ventilation pipe 31 and a fixing seat 32. The ventilation pipe 31 is L-shaped and is a passage for circulating air. The ventilation pipe 31 is fixedly connected to the mounting plate 1 through the fixing seat 32, and the position of the ventilation pipe 31 is fixed. The transmission shaft 22 passes through the ventilation pipe 31, and one end of the ventilation pipe 31 close to the cleaning column 23 is set in a trumpet shape to facilitate air to enter the ventilation pipe 31. The dust collecting assembly 3 also includes a first fixing sleeve 33, a second fixing sleeve 34, and a fixing plate 35. The first fixing sleeve 33 is arranged in the ventilation pipe 31 and one end is fixedly connected to the ventilation pipe 31. The transmission shaft 22 is rotatably connected to the first fixing sleeve 33. The position of the ventilation pipe 31 is fixed, so that the transmission shaft 22 will not drive the ventilation pipe 31 to rotate when rotating. The second fixed sleeve 34 is arranged on the ventilation pipe 31 and sleeved on the outer ring of the transmission shaft 22. Multiple groups of fixed plates 35 are arranged in a circular array and one end is fixedly connected to the outer ring of the second fixed sleeve 34. The ends of the multiple groups of fixed plates 35 away from the second fixed sleeve 34 are all fixedly connected to the inner wall of the ventilation pipe 31. The fixed plates 35 make the second fixed sleeve 34 fixedly connected to the inner wall of the ventilation pipe 31, so that the transmission shaft 22 rotates smoothly. The dust collection component 3 also includes a sealing block 36 arranged at the end of the second fixed sleeve 34 away from the first fixed sleeve 33. The sealing block 36 is fixedly connected to the outer ring of the transmission shaft 22. The sealing block 36 is rotatably connected to one end of the second fixed sleeve 34 and the cross-section is L-shaped and cooperates with each other to prevent dust from entering the gap between the transmission shaft 22 and the second fixed sleeve 34. The dust collection component 3 also includes a rotating sleeve 37 and a fan blade 38. The rotating sleeve 37 is arranged between the first fixed sleeve 33 and the second fixed sleeve 34 and is fixedly connected to the outer ring of the transmission shaft 22. When the transmission shaft 22 rotates, the rotating sleeve 37 is driven to rotate synchronously. The plurality of blades 38 are arranged in an annular shape on the outer ring of the rotating sleeve 37. When the rotating sleeve 37 rotates, the blades 38 are driven to rotate, thereby allowing air to flow. The first fixed sleeve 33 and the second fixed sleeve 34 are both provided with convex rings at one end close to the rotating sleeve 37. The two ends of the rotating sleeve 37 are provided with sliding grooves corresponding to the convex rings to prevent dust from entering the gap between the first fixed sleeve 33 and the second fixed sleeve 34 and the transmission shaft 22.

[0033] Finally, the dust cleaning machine also includes a collection mechanism 4 installed on the mounting plate 1 for collecting dust. The collection mechanism 4 includes a sealing cover 41, a collection tank 42, and a filter screen 43. The sealing cover 41 is fixedly connected to one side of the mounting plate 1. The sealing cover 41 is fixedly connected to one end of the ventilation pipe 31 away from the cleaning column 23. The position of the sealing cover 41 is fixed. The fan blades 38 drive the air flow. The air enters from one end of the ventilation pipe 31 close to the cleaning column 23, and is discharged from the other end and passes through the sealing cover 41. The collection tank 42 is threadedly connected to the sealing cover 41. A plurality of ventilation holes are provided on the side of the collection tank 42 away from the sealing cover 41 to facilitate air circulation, so that the air flowing into the ventilation pipe 31 passes through the collection tank 42. The filter screen 43 is installed in the collection tank 42 to facilitate filtering dust in the air, prevent secondary pollution, and not hinder the flow of air.

[0034] In this embodiment, after the chiseling of the repair position is completed, the handle 11 is held and the servo motor 21 is started. The servo motor 21 drives the cleaning column 23 to rotate through the transmission shaft 22, so that the bristles 24 rotate synchronously, so that the bristles 24 are close to the chiseling position. Therefore, the bristles 24 can sweep larger debris away from the repair position when rotating. At the same time, the dust generated by the chiseling diffuses into the surrounding environment due to the sweeping of the bristles 24. At the same time, the transmission shaft 22 drives the rotating sleeve 37 to rotate and drives the fan blades 38 to rotate, so that the air enters the ventilation pipe 31 through one end of the ventilation pipe 31 close to the cleaning column 23, and is discharged from the other end of the ventilation pipe 31 to the collection tank 42, and the air flows out through the ventilation hole opened on the side of the collection tank 42 away from the sealing cover 41. When the air passes through the filter 43, the dust in the air is filtered to prevent the dust from falling into the repair position again and causing secondary pollution, thereby effectively cleaning the dust at the chiseling position, and then after re-casting the concrete, the bonding strength of the new and old concrete bonding surfaces is improved to prevent cracks and falling off, thereby improving the quality of the repair project.

[0035] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
