Technical Field

[0001] The utility model belongs to the technical field of tunnel lamp cleaning, and relates to automatic cleaning equipment for tunnel lamps based on laser dust removal technology. Background Art

[0002] The environment of a tunnel not only affects driving comfort, but also driving safety. The most intuitive thing about operating a tunnel is lighting, so the cleaning of tunnel lamps used for tunnel lighting is receiving more and more attention. Due to the influence of vehicle exhaust and dust, tunnel operation is prone to deposition and corrosive gases and dust on the surface of lamps. For the cleaning of tunnel lamps, traditional cleaning methods require manual operation or the use of large cleaning equipment, which is time-consuming and labor-intensive, and also poses certain safety risks.

[0003] At present, with the development of science and technology, the application of tunnel lamp cleaning vehicles is becoming more and more widespread, mainly including two types: one is a roller brush tunnel lamp cleaning vehicle, and the other is a high-pressure water tunnel lamp cleaning vehicle. Both methods are very useful tunnel cleaning tools, but their disadvantages are also obvious.

[0004] (1) The disadvantages of roller brush tunnel lamp cleaning vehicles are as follows:

[0005] The cleaning effect is not thorough enough: the roller brush cleaning can only remove the attachments on the surface of the lamp, and it is difficult to clean the deeper stains;

[0006] Secondary pollution to lamps: Roller brush cleaning may remove pollutants such as dust or oil attached to the surface of lamps, but it will also cause secondary pollution to lamps;

[0007] It is suitable for more common lamps, but may not be suitable for cleaning some decorative lamps.

[0008] (2) The disadvantages of high-pressure water tunnel lighting cleaning vehicles are as follows:

[0009] High water consumption: High-pressure water cleaning relies on a large amount of water flow for cleaning, so it consumes a lot of water resources;

[0010] Low cleaning efficiency: Stubborn stains may require multiple washes to be cleaned, and the cleaning efficiency is not as high as other cleaning methods;

[0011] May cause damage to lamp parts: High-pressure water may hit lamp parts too hard and cause damage, so please operate with caution. Utility Model Content

[0044] The purpose of the utility model is to develop a tunnel lamp cleaning device that can make the lamps get a deeper and more thorough cleaning, and is safe and efficient to operate, so as to solve the problems existing in the traditional cleaning method. The utility model uses a vehicle-mounted wax spraying device to spray a certain thickness of special wax on the lamps in advance. The wax liquid has excellent environmental protection performance and dustproof, waterproof and wear-resistant properties, and can be completed by automatic spraying, and the coating can be removed by CO2 laser. After the lamp is sprayed with a wax layer, the dust generated during operation is directly attached to the wax layer (at the same time, the wax layer can ensure the cleanliness of the lamp for a longer time). When the lamp needs to be dusted, the wax layer sprayed on the lamp is removed by laser dust removal technology, without any pollutant emissions, no secondary pollution, high cleaning efficiency, and can quickly and deeply remove surface dirt to ensure cleaning quality.

[0045] Laser dust removal technology uses the principle of laser interference. Under the irradiation of the laser beam, dust molecules or particles absorb the laser energy and then evaporate, desorb, or explode and burn, thereby achieving efficient gas purification and surface cleaning. The utility model uses laser dust removal technology to clean tunnel lamps, making lamp cleaning operations more reliable, safe and efficient, bringing revolutionary changes to tunnel lamp cleaning.

[0050] For the use of automatic cleaning equipment for tunnel lamps based on laser dust removal technology, refer to Figure 2 , as follows:

[0051] (1) When the tunnel lamps are cleaned for the first time, they need to be waxed in advance.

[0052] Step 1. Preparation: Before starting the automatic cleaning equipment for tunnel lamps, you need to prepare equipment and materials for spraying wax, such as spray guns, wax liquid, etc.

[0053] Step 2. Arrive at the first lamp: The automatic cleaning device for tunnel lamps enters the tunnel and moves to the first lamp position that needs to be sprayed with wax.

[0054] Step 3. Positioning and spraying wax: According to the information determined by the light source and the sensor, the tunnel lamp automatic cleaning device will automatically position and start the wax spraying operation. You can use a spray gun to spray the wax liquid evenly on the surface of the lamp to protect its surface from oxidation and damage. The thickness of the first wax spray on the lamp is about 0.3mm.

[0055] Step 4. Cleaning and re-inspection: After the wax is sprayed, the automatic cleaning equipment of the tunnel lamp will perform necessary cleaning operations to remove excess wax and dirt. After that, a re-inspection will be carried out to ensure that the effect of the spray wax meets the requirements.

[0056] Step 5. Move to the next lamp: After completing the wax spraying of the current lamp, the tunnel lamp automatic cleaning device will automatically move to the next lamp position that needs to be sprayed with wax, and repeat the above process until all lamps in the tunnel are cleaned and all wax spraying processes are completed. The thickness of the first wax spray on the lamp is about 0.3mm.

[0057] Step 6. Arrange equipment: After all lamps are cleaned and wax sprayed, the automatic cleaning equipment of tunnel lamps needs to be arranged and maintained. At the same time, the cleaning effect, wax liquid usage, etc. can be evaluated and recorded.

[0058] Step 7. Turn the vehicle around. The initial wax spray has solidified during the operation.

[0059] Step 8. Locate the first lamp. Start the automatic cleaning equipment for tunnel lamps, preheat and check its operating status. At the same time, the traffic in the tunnel needs to be closed to ensure the safe cleaning process.

[0060] Step 9. Based on the information determined by the light source and the sensor, the tunnel lamp automatic cleaning device will autonomously locate and start the cleaning operation. The laser removes the thickness of the first wax spray on the lamp by about 0.3mm. The first cleaning of the lamp is completed.

[0061] Step 10. Spray wax on the first lamp for the second time with a wax thickness of 0.6mm.

[0062] Step 11. Cleaning and re-inspection: After the wax is sprayed, the automatic cleaning equipment of the tunnel lamp will perform necessary cleaning operations to remove excess wax and dirt. After that, a re-inspection will be carried out to ensure that the effect of the spray wax meets the requirements.

[0063] Step 12. Position the next lamp. Repeat Step 9, Step 10, and Step 11 until all lamps have been sprayed with base wax (keep the base wax thickness at 0.6mm).

[0064] (ii) When the tunnel lamps are not cleaned for the first time, wax is applied after laser cleaning.

[0065] Step 1. Preparation: Before starting the automatic cleaning equipment for tunnel lamps, you need to prepare equipment and materials for spraying wax, such as spray guns, wax liquid, etc.

[0066] Step 2. Start the automatic cleaning equipment for tunnel lamps, preheat it and check its operating status. At the same time, you need to close the traffic in the tunnel to ensure the safety of the cleaning process.

[0067] Step 3. Arrive at the first lamp: The tunnel lamp automatic cleaning device enters the tunnel, moves to the first lamp position that needs to be cleaned, and sets a light source and sensor above the lamp to determine the position and status of the lamp.

[0068] Step 4. Positioning and cleaning: Based on the information determined by the light source and sensor, the tunnel lamp automatic cleaning equipment will autonomously position and start the cleaning operation. Specifically, the laser dust remover can emit a high-frequency, high-intensity laser beam to instantly evaporate the dust and dirt on the surface of the lamp and absorb the remaining smoke and dust, thereby achieving a cleaning effect. This time, the 0.6mm base wax of the lamp was removed to a thickness of 0.3mm, and 0.3mm of base wax was left.

[0069] Step 5. Re-inspection: After the cleaning operation is completed, a re-inspection will be carried out to ensure that the cleaning operation effect meets the requirements.

[0070] Step 6. Positioning and wax spraying: According to the information determined by the light source and the sensor, the tunnel lamp automatic cleaning device will automatically position and start the wax spraying operation. You can use a spray gun to spray the wax liquid evenly on the surface of the lamp to protect its surface from oxidation and damage. This time the wax is sprayed 0.3mm, plus the base wax 0.3mm. After this wax spraying, the lamp has a total of 0.6mm of base wax after this work is completed.

[0071] Step 7. Cleaning and re-inspection: After the wax is sprayed, the automatic cleaning equipment of the tunnel lamp will perform necessary cleaning operations to remove excess wax and dirt. After that, a re-inspection will be carried out to ensure that the effect of the spray wax meets the requirements.

[0072] Step 8. Move to the next lamp: After the wax spraying is completed, the tunnel lamp automatic cleaning equipment will automatically move to the next lamp position that needs to be cleaned, and repeat Step 4, Step 5, Step 6, and Step 7 until all the lamps in the tunnel are cleaned and the wax on the lamp surface is re-sprayed.

[0073] Step 9. Arrange equipment: After all lamps are cleaned, the automatic cleaning equipment of tunnel lamps needs to be arranged and maintained. At the same time, the cleaning effect and cleaning efficiency can be evaluated and recorded.

[0074] Compared with the prior art, the utility model can clean lamps more quickly and thoroughly, reducing cleaning time and workload. The cleaning effect of traditional dust collector robots is poor, while the laser dust removal technology adopted by the utility model can better remove dust and dirt, and the cleaning effect is more superior. At the same time, with the support of the wax spraying device, the utility model can form a layer of special wax layer, extend the cleaning cycle of the lamp, reduce maintenance costs, and improve the overall hygiene of the tunnel. In addition, since the laser dust removal technology removes the wax previously applied to the lamp, that is, indirectly removes dust from the lamp, it will not cause any damage to the lamp. In short, the innovation of the utility model is mainly reflected in the laser dust removal and vehicle-mounted thin wax spraying, so as to solve the problems of low efficiency and high cost in the traditional manual or dust collector robot cleaning of tunnel lamps, and realize a faster, more economical and efficient lamp cleaning method, thereby improving the efficiency and quality of tunnel cleaning and maintenance.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
