[0002] The laser profiler uses non-cooperative target laser ranging technology and precise angle measurement technology, closely combines polar coordinate measurement methods with computer technology, and cooperates with professional graphics processing software to collect road structure texture data. The multifunctional laser profiler collects local texture and macro texture data of the road surface, analyzes and forms road flatness, rutting, and structural depth result data, and timely understands the damage condition and cause of the inspected road surface, providing real and effective data support for the scientific maintenance of the municipal roads. It is usually installed on the surface of a road inspection vehicle. When the vehicle is in normal driving condition, it can automatically complete the collection, analysis, classification and storage of road pavement images, road shape, three-dimensional images of road facilities, flatness and road geometric parameters.

[0021] like Figure 1~Figure 4 As shown, the present embodiment proposes an auxiliary dust removal mechanism for a laser profiler, comprising a mounting frame 1, a laser profiler mounting box 2 and a dust removal component 3 are fixedly mounted on the surface of the mounting frame 1, the surface of the dust removal component 3 is arranged on the right side of the laser profiler mounting box 2, a laser profiler is arranged inside the laser profiler mounting box 2, the dust removal component 3 comprises a shell 31, a dust hopper 32 is fixedly mounted on the lower right end of the shell 31, a dust storage frame 33 is arranged on the left side of the dust hopper 32, the surface of the dust storage frame 33 is fixedly connected to the lower surface of the shell 31, a fan box 34 is fixedly mounted on the left side of the shell 31, and the inner surface of the fan box 34 is fixedly mounted on the outer surface of the shell 31. A negative pressure fan 35 is fixedly installed on the part, and a first air outlet 36 and a second air outlet 37 are opened on the left side of the negative pressure fan 35. The second air outlet 37 faces the detection plane of the laser profiler. An air guide scoop 38 is fixedly installed on the surface of the first air outlet 36, and the air guide scoop 38 faces the ground. An exhaust pipe 40 is fixedly installed on the surface of the fan box 34. A through groove 41 is opened on the side wall of the exhaust pipe 40. A filter element 42 is installed on the exhaust pipe 40. One end of the mounting frame 1 is fixedly installed on the surface of the road inspection vehicle. Several groups of filter elements 42, exhaust pipes 40, extension blocks 43, threaded grooves 44 and grooves 46 are provided.

[0022] In this embodiment, the negative pressure fan 35 is started to exhaust air, and the dust on the ground is sucked into the interior of the shell 31 through the exhaust pipe 40, the through groove 41 and the dust hopper 32, so that the dust on the ground is reduced. After the dust and air enter the interior of the shell 31, the dust is filtered by the filter element 42. The clean air after filtration passes through the through groove 41, the exhaust pipe 40, the fan box 34 and finally discharged through the first air outlet 36 and the second air outlet 37. The air exhausted through the first air outlet 36 is blown to the ground through the wind guide 38, and the dust on the ground that has not been extracted cleanly is blown away from the bottom of the laser profiler. The air exhausted through the second air outlet 37 forms a wind layer parallel to the detection surface on the detection surface of the laser profiler, so as to avoid dust adhering to the detection surface of the laser profiler as much as possible, improve the data collection accuracy, reduce the influence of road dust on the laser profiler, and ensure the normal and stable operation of the laser profiler. The filter element 42, the exhaust pipe 40, the extension block 43, the threaded groove 44 and the groove 46 are arranged in several groups according to the length of the shell 31.

[0023] Example 2

[0024] like Figure 1~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that an extension block 43 is fixedly installed on the right end of the exhaust duct 40, a threaded groove 44 is provided on the side wall of the extension block 43, a threaded limit block 45 is threadedly connected to the surface of the threaded groove 44, a cover plate 39 is hinged on the upper surface of the outer shell 31, a groove 46 is provided on the surface of the cover plate 39, a rotating block 47 is rotatably installed on the surface of the outer shell 31, and a limiting pressure block 48 is fixedly installed on the upper end of the rotating block 47.

[0025] In this embodiment, the filter element 42 is limited and fixed by a threaded limit block 45 threadedly connected to the surface of the threaded groove 44. When the filter element 42 needs to be replaced, the threaded limit block 45 is rotated to remove the threaded limit block 45, which is convenient for replacing the filter element 42. The filtered dust is stored by the dust storage frame 33, and the cover plate 39 is limited by the limit pressure block 48. When the dust inside the dust storage frame 33 needs to be processed or the filter element 42 needs to be replaced, the limit pressure block 48 and the rotating block 47 are rotated to rotate the limit pressure block 48 to the top of the groove 46, so that the cover plate 39 can be rotated to open the top of the dust storage frame 33 for convenient cleaning and replacement.

[0026] During operation, the negative pressure fan 35 is started to exhaust air, and the dust on the ground is sucked into the interior of the housing 31 through the exhaust pipe 40, the through slot 41 and the dust hopper 32, so that the dust on the ground is reduced. After the dust and air enter the interior of the housing 31, the dust is filtered by the filter element 42. The clean air after filtration passes through the through slot 41, the exhaust pipe 40, and the fan box 34 and is finally discharged through the first air outlet 36 and the second air outlet 37. The air exhausted through the first air outlet 36 is blown to the ground through the wind guide 38, and the dust on the ground that has not been extracted cleanly is blown away from the bottom of the laser profiler. The air exhausted through the second air outlet 37 forms a wind layer parallel to the detection surface on the detection surface of the laser profiler, avoiding dust as much as possible. It is bonded to the detection surface of the laser profiler, and the filter element 42 is limited and fixed by a threaded limit block 45 which is threadedly connected to the surface of the threaded groove 44. When the filter element 42 needs to be replaced, the threaded limit block 45 is rotated to remove the threaded limit block 45, which is convenient for replacing the filter element 42. The filtered dust is stored through the dust storage frame 33, and the cover plate 39 is limited by the limit pressure block 48. When the dust inside the dust storage frame 33 needs to be processed or the filter element 42 needs to be replaced, the limit pressure block 48 and the rotating block 47 are rotated to rotate the limit pressure block 48 to the top of the groove 46, so that the cover plate 39 can be rotated to open the top of the dust storage frame 33 for easy cleaning and replacement.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
