Description

Technical Field

[0001] The present invention relates to the technical field of cleaning dirt inside large industrial rectangular ventilation ducts, and specifically to a cleaning robot for industrial ventilation ducts. Background Art

[0002] In the field of industrial production, the cleaning of ventilation ducts is crucial for maintaining a good production environment and ensuring the normal operation of equipment. However, there are many problems and challenges in the existing industrial ventilation duct cleaning technologies.

[0003] Traditional industrial ventilation duct cleaning methods mainly rely on manual operation. Workers need to enter the inside of the ventilation duct and carry out cleaning work in a space full of dust, oil stains and narrow spaces. This not only has an extremely harsh working environment, posing a threat to the physical health of workers, but also has a very high labor intensity and extremely low efficiency. Due to the limitations of manual operation, it is difficult to ensure a comprehensive cleaning of the inside of the duct, and it is easy to miss some corners and stubborn stains.

[0004] Some existing mechanical cleaning equipment also has deficiencies in terms of function and performance. The size and structural design of some equipment are unreasonable and cannot adapt to ventilation ducts of different specifications and shapes. Especially for ducts with a height in the range of 350mm - 1500mm, existing equipment often fails to achieve an ideal cleaning effect.

[0005] Some cleaning equipment lacks effective monitoring and control means, cannot understand the cleaning situation inside the duct in real time, and is difficult to ensure the cleaning quality. At the same time, existing cleaning equipment also has defects in dirt treatment, and cannot collect and process the dirt generated during the cleaning process in a timely and effective manner, resulting in the re - spread of dirt inside the duct and affecting the cleaning effect.

[0006] Moreover, most of the existing equipment does not have a flexible lifting mechanism and the ability to move freely, and it is difficult to cope with the complex structure inside the duct and the cleaning requirements at different heights. For example, for the demand of height adjustment, existing equipment usually cannot accurately adapt to a range like 350mm - 1500mm, resulting in some areas not being cleaned. In terms of free movement, existing equipment may be affected by factors such as obstacles and slopes inside the duct, and cannot smoothly reach all positions on the inner wall of the duct, thus affecting the comprehensiveness and effect of cleaning. Summary of the Invention

[0007] The purpose of the present invention is to overcome the defects and deficiencies existing in the prior art, and provide a cleaning robot for industrial ventilation ducts to solve the problems of existing industrial ventilation duct cleaning equipment in terms of adapting to the duct height range, flexible movement, dirt treatment, and cleaning effect monitoring.

[0041] In the present invention, LED lights 31 are installed on the front and rear sides of the chassis 1 and the rear side of the connecting seat 5 to provide the required lighting conditions for the shooting of the front camera 10 and the rear camera 11.

[0043] In addition, guide wheels 33 are installed at the four corners of the chassis 1, which can move along the two side walls of the industrial ventilation duct to provide a guiding function.

[0044] In the present invention, a first dust suction quick-connect male head 34 communicating with the dust suction channel is connected to the rear end of the chassis 1, a second dust suction quick-connect male head 35 communicating with the inside of the dust collection cavity is connected to one side of the dust collection box 12, and dust suction quick-connect female heads 36 are connected to both ends of the dust suction pipe 15.

[0047] Thus, by unlocking the buckle 40 and turning the control box 18 upward, the support rod 41 is unfolded accordingly to support the control box 18, and the wiring and maintenance of the dust suction motor 14 can be realized.

[0048] In addition, by opening the dust cleaning cover plate 42 to open the dust cleaning port, the collected dirt and dust can be removed.

[0049] The present invention will be further described below with reference to the accompanying drawings: During use, place the cleaning end of the present invention at the inlet of the industrial ventilation duct (rectangular duct). By manually operating the lifting switch 23, the central processing unit sends control instructions to the first cylinder 29 and the second cylinder 30 to control their operations respectively. To control the lifting part, that is, to control the long lifting arm 3 and the short lifting arm 4 to perform adaptive lifting, so that it can flexibly adapt to ducts of different heights within the range of 350 mm - 1500 mm.

[0050] Then, by manually operating the walking rocker 20, the walking speed control switch 21 and the cleaning brush switch 22, the central processing unit sends control instructions to the walking motor 26, the first cleaning motor 27 and the second cleaning motor 28 to control their operations respectively, so as to realize the control of the operation of the walking part and the cleaning part, so that the walking wheels 2 walk along the bottom wall of the industrial ventilation duct at a set path and speed, and the top cleaning brush 7, the bottom cleaning brush 8 and the strip brush 9 clean the pipe wall.

[0051] During the cleaning process, the dirt swept is driven by the airflow generated by the suction motor 14 and enters the dust collection chamber successively through the suction port 13, the suction channel and the suction pipe 15. After being filtered by the filter barrel, the dirt and dust are intercepted in the dust collection chamber for collection.

[0052] In addition, the front camera 10 and the rear camera 11 capture the internal images of the industrial ventilation duct in real time and send them to the display screen 19 for real-time display, so that the operator can monitor the cleaning situation inside the duct in real time, timely discover the areas where the cleaning is not thorough, and adjust the cleaning strategy.

[0053] As can be seen from the above, the present invention has the following characteristics: First of all, the present invention designs a unique two-stage lifting mechanism, that is, the long lifting arm 3 and the short lifting arm 4, which can accurately adjust the cleaning height so that it can flexibly adapt to ducts of different heights within the range of 350 mm - 1500 mm. For existing solutions, it is generally difficult to clean to such heights and usually can only handle ducts within a lower or specific height range, which greatly limits their application scenarios. The lifting mechanism of the present invention greatly improves the versatility and applicability of the equipment.

[0054] Secondly, the present invention is equipped with a top cleaning brush 7 and a bottom cleaning brush 8 driven by motors, which can provide strong and stable cleaning power and effectively remove stubborn dirt on the inner wall of the duct. At the same time, the position and angle of the top cleaning brush can be adjusted according to the actual situation of the duct to ensure effective cleaning of all parts of the duct.

[0055] Furthermore, the present invention has the ability to move freely within the pipeline, can easily bypass obstacles, and reach any position on the inner wall of the pipeline, achieving a full - range and dead - angle - free cleaning. In contrast, the existing equipment is not flexible enough in movement and is often restricted by the complex environment inside the pipeline, resulting in some areas not being cleaned.

[0056] In addition, high - definition cameras 10 and 11 are installed at the front and rear of the cleaning robot of the present invention. Operators can monitor the cleaning situation inside the pipeline in real time, promptly discover areas where the cleaning is not thorough, and adjust the cleaning strategy, greatly improving the cleaning quality and controllability. This is an effective monitoring means that is generally lacking in existing equipment.

[0057] Finally, the present invention directly sucks the dirt generated during the cleaning process into the dust collection box 12 at the control end, that is, into the dust collection chamber, through the suction pipe 15, avoiding the re - diffusion and residue of the dirt in the pipeline, and ensuring the durability and stability of the cleaning effect. The existing dirt treatment methods are usually not timely and effective enough, and are prone to causing secondary pollution.

[0058] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0059] Therefore, the above - mentioned are only the preferred embodiments of the present application, and are not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
