Technical Field

[0001] The utility model belongs to the technical field of laser cleaning, and in particular relates to a long-distance laser cleaning device. Background Art

[0002] The scientific name of laser cleaning is laser ablation or photoablation. Simply put, it uses a high-energy laser beam to irradiate the surface of an object, causing the dirt, rust or coating on the metal surface to evaporate or peel off instantly, and quickly and effectively remove the attachments or surface coatings on the surface of the object, thereby achieving a clean process. Laser cleaning has the characteristics of no grinding, no contact, no heat effect, and is suitable for objects of various materials. It is considered to be the most reliable and effective solution.

[0003] When existing laser cleaning devices use a laser transmitter to emit high-frequency short-pulse lasers to irradiate coatings or dirt, the coatings or dirt absorb the laser energy to evaporate and peel off, which may produce a large amount of dust particles and harmful gases, thereby causing air pollution.

The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0019] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appearing in various places in the specification is not necessarily referring to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Please refer to Figures 1-4, an embodiment provided by the present utility model: a long-distance laser cleaning device, which includes a protective box 1. A notch one 2 is opened inside the protective box 1. A box door 12 is rotatably connected to the side wall of the protective box 1. The external dimensions of the side wall of the box door 12 are adapted to the internal dimensions of the notch one 2 to conveniently close the notch one 2, which can reduce the emission of waste and waste gas. The inner top end of the notch one 2 is movably connected with a laser emitter 3 through a slide rail to adjust the position of the laser emitter 3. When the laser emitter 3 is powered on, it can generate high-frequency short-pulse laser to irradiate the coating or dirt. The coating or dirt absorbs the laser energy and can evaporate and peel off, thereby realizing the cleaning of the object surface. A bracket 4 is clamped on the inner side wall of the notch one 2 to support the object to be cleaned. A plurality of notch two 5 are opened on the surface of the bracket 4 to facilitate the falling of the removed dust particles. The bottom end of the protective box 1 is fixedly welded with a base 6. A blower 9 is fixedly bolted to the bottom end of the base 6. A connecting pipe 15 is inserted into the top end of the blower 9. The connecting pipe 15 is a PP steel wire telescopic pipe, which is convenient for bending and deforming. A cylinder 13 is fixedly bolted to the side wall of the protective box 1 close to the connecting pipe 15. The output end of the cylinder 13 penetrates through the protective box 1 and is fixedly connected with an air inlet hood 11 through a coupling. The other end of the connecting pipe 15 penetrates through the protective box 1 and is inserted into the side wall of the air inlet hood 11. A filter 14 is inserted into the output port of the side wall of the blower 9. Starting the cylinder 13 can adjust the position of the air inlet hood 11 below the bracket 4, expanding the absorption range of dust and waste gas. Then starting the blower 9 can discharge the dust and waste gas into the interior of the filter 14 for filtration. A filter element 19 is clamped inside the blower 9. The filter element 19 is made of activated carbon to adsorb waste and waste gas, thereby reducing the emission of dust and waste gas. The end of the blower 9 is threadedly connected with an end cover 20. A hole groove is opened on the side wall of the end cover 20 to facilitate the discharge of the filtered air. Rotating the end cover 20 can remove the end cover 20, improving the convenience of replacing the filter element 19.

[0021] A notch three 10 is opened at the inner bottom of the notch one 2. The notch three 10 penetrates through the bottom end of the protective box 1. A dovetail groove 16 is opened at the bottom end of the air inlet hood 11. A dovetail block 17 is clamped inside the dovetail groove 16. The external dimensions of the dovetail block 17 are adapted to the internal dimensions of the dovetail groove 16. A brush 18 is embedded at the bottom end of the dovetail block 17. The brush 18 moves synchronously with the air inlet hood 11. When moving, it can sweep out large-particle waste from the notch three 10. Two clamping claws 7 are symmetrically and fixedly welded to the bottom end of the protective box 1 close to the notch three 10. Both of the two clamping claws 7 are L-shaped. A waste box 8 is clamped inside each of the clamping claws 7. The top end of the waste box 8 is directly opposite to the bottom end of the notch three 10, facilitating the collection of large-particle waste.

[0022] Working principle: When this long-distance laser cleaning device is in use, the operator first externally connects the power supply, places the object on the top of the bracket 4, and then rotates the box door 12 to close the first notch 2. The laser emitter 3 can be remotely controlled. When the laser emitter 3 is powered on, it can generate high-frequency short-pulse laser to irradiate the coating or dirt on the surface of the object. The coating or dirt absorbs the laser energy and can evaporate and peel off, thus realizing the cleaning of the object surface. The waste cleaned down can fall from the second notch 5. Starting the cylinder 13 can adjust the position of the air intake hood 11 below the bracket 4, expanding the absorption range of dust and waste gas. Then starting the blower 9 can discharge the dust and waste gas into the interior of the filter 14 for filtration, thereby reducing the emission of dust and waste gas.

[0023] Secondly, the brush 18 can move synchronously with the air intake hood 11. When the brush 18 moves, it can sweep the large-particle waste deposited at the inner bottom end of the first notch 2 out from the third notch 10, and the waste can fall into the waste box 8 to complete the collection.
