Description

Technical Field

[0001] The present invention relates to the technical field of air duct outer wall cleaning, and specifically provides a robot for cleaning the outer wall of an air duct. Background Art

[0002] Air ducts can be used in the industrial field, playing the roles of ventilation, heat dissipation, and material transportation. At the same time, air ducts can also be used in the construction field, playing the roles of indoor ventilation and fire smoke exhaust. After long-term use, dirt such as dust and oil stains will accumulate. At this time, a robot for cleaning the outer wall of the air duct is needed to clean it. For example, in the Chinese patent application with the application number 202110895196.5 and the application date of August 5, 2021, a cleaning robot for a wind power tower barrel, which is designed according to the actual situation, omits the magnetic track, does not cause secondary damage to the surface of the tower barrel, and does not require a sling, making it more convenient to use. The cleaning components are arranged circumferentially and can rotate around the center of the tower barrel, so there is no need to adjust the working angle position. The robot only needs to walk up and down along the tower barrel to complete the cleaning, greatly improving the cleaning efficiency. There is also a Chinese patent application with the application number 202410815295.1 and the application date of June 24, 2024, a pull-arm type climbing robot for the outer wall operation of a large wind power tower barrel. When it works, the driving wheel is rotated by the first motor. Through the mutual cooperation of the second chute, the second slider, and the third spring, the third spring applies pressure, and the cleaning belt can be attached to the surface of the arc-shaped barrel wall, cooperating with the liquid sprayed by the nozzle to clean the tower barrel. When the first motor drives the sliding rod to rotate, under the action of the runner and the corrugated groove, the driving wheel moves back and forth while rotating, and drives the directional wheel and the cross bar to move back and forth through the connecting rod, further enhancing the cleaning effect of the cleaning belt on the barrel wall.

[0003] During the use process, when cleaning the air duct, it is necessary to spray a solvent on the outer wall of the air duct, such as a cleaning solvent or foam. However, the robots in the above applications do not have the function of assisting in mixing the solvent during the use process, which leads to a decline in the cleaning effect and brings unnecessary trouble to the cleaning of the outer wall of the air duct.

[0010] Preferably, the reciprocating mechanism includes a limiting rod fixedly connected to the surface of the material box, an external connecting plate is sleeved and connected to the surface of the limiting rod, and a rack is fixedly connected to the surface of the external connecting plate.

[0011] Preferably, the top view of the limiting rod is an inverted "U" shape, a cam corresponding to the external connecting plate is fixedly connected to the end of the long pin, an inner rod is rotatably arranged inside the material box, and a connecting gear meshed with the rack is fixedly connected to the surface of the inner rod.

[0012] Preferably, a connecting spring for elastic reset is fixedly connected to the surface of the external connecting plate, and the other side of the connecting spring is fixedly connected to the inner wall of the limiting rod.

[0013] Preferably, the fixing plate is fixedly connected to the surface of the inner rod, the fixing plates are equally angularly distributed on the surface of the inner rod, and through holes are equally spaced on the surface of the fixing plate.

[0014] Preferably, a vertical plate is fixedly connected to the upper surface of the bottom plate, a cross bar is rotatably arranged inside the vertical plate, the swinging mechanism includes an auxiliary plate fixedly connected to the surface of the cross bar, a first magnet is fixedly connected to the upper surface of the auxiliary plate at equal intervals, and the nozzle assembly and the material box are connected through an external hose.

[0015] Preferably, a movable block is movably connected to the surface of the rotating shaft through a bidirectional thread, and a second magnet is fixedly connected to the lower surface of the movable block. Moreover, the magnetic pole on the lower surface of the second magnet is the same as the magnetic pole on the upper surface of the first magnet. A limiting strip penetrating through the inside of the movable block is fixedly connected to the inner wall of the vertical plate, and a jacking rod is fixedly connected to the upper surface of the bottom plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] Adopting a novel structural design, the cleaning module is used to complete the cleaning of the required positions. During the use process, the materials in the mixing material box are mixed by the long pin and the mixing blades, which is convenient for subsequent cleaning work. At the same time, during the movement of the robot, the inner rod and the fixed plate are in a reciprocating swinging state, optimizing the mixing effect. Moreover, through holes are evenly distributed on the surface of the fixed plate, enabling the materials to move and exchange better, improving the working efficiency. In addition, during the work, the spray head assembly can spray a cleaning agent on the outer wall of the air duct, facilitating the cleaning work of the cleaning module. At the same time, a reciprocating mechanism is also provided to make the spray head assembly swing, expanding the cleaning range and improving the working efficiency. The specific content is as follows:

[0018] (1) For this air duct outer wall cleaning robot, during the work, the control module drives the driving module to work. At the same time, the lifting module enables the robot to have better flexibility. In addition, the quick installation module is used to quickly assemble the cleaning module, and the cleaning module is used to clean the required positions, while the anti-falling module ensures the stability of the robot's work.

[0019] Furthermore, during the movement of the robot, the driving module drives the connecting shaft to rotate. When the connecting shaft rotates, the rotating shaft is driven to rotate inside the vertical plate through the pulley. When the rotating shaft rotates, the long pin is driven to rotate through the first bevel gear and the second bevel gear. When the long pin rotates, the mixing blades are driven to rotate. At this time, the mixing blades play a role in mixing the materials inside the mixing material box, facilitating subsequent cleaning work. The mixing blades are symmetrically distributed on both sides of the material box, optimizing the effect of the mixing blades.

[0020] (2) For this air duct outer wall cleaning robot, when the long pin rotates, the long pin drives the cam to rotate synchronously. When the cam rotates, it will intermittently contact the external plate. At this time, under the action of the cam, the limiting rod, and the connecting spring, the external plate and the rack perform a reciprocating linear motion in the horizontal direction. When the external plate moves, the rack is driven to move synchronously. Furthermore, the inner rod rotates reciprocally inside the material box under the action of the rack and the connecting gear. At this time, the inner rod drives the fixed plate to move synchronously, and thus the materials inside the material box can be better mixed, optimizing the mixing effect.

[0021] Furthermore, the fixing plates are evenly distributed on the surface of the inner rod, which can better mix the materials. At the same time, through holes are evenly distributed on the surface of the fixing plates, enabling the materials to move and exchange better, thus improving the working efficiency.

[0022] (3) When the air duct outer wall cleaning robot is working, the robot sprays the cleaning agent inside the material box through the nozzle assembly, facilitating the subsequent cleaning work of the cleaning module and improving the working efficiency.

[0023] Furthermore, the rotating shaft and the movable block are connected by a bidirectional thread. When the rotating shaft rotates, the rotating shaft drives the movable block to perform a reciprocating linear motion in the horizontal direction through the limiting strip. At this time, the first magnet on the lower surface of the movable block will intermittently approach the second magnet. Then, under the action of the mutually repulsive magnetic force and its own gravity, the auxiliary plate and the cross bar rotate inside the vertical plate, and the cross bar drives the nozzle assembly to move synchronously. At this time, the working range of the nozzle assembly increases and the working efficiency is improved.

[0024] Furthermore, when the nozzle assembly swings, the ejector rod plays a role in restricting the rotation angle of the nozzle assembly, preventing the nozzle assembly from over-rotating and ensuring stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The present invention provides the following technical solution: A cleaning robot for the outer wall of a wind tunnel.

[0038] Embodiment 1:

[0039] By setting the cleaning module 5, the cleaning work of the wind tunnel can be completed. At the same time, by setting the mixing blade 18, the materials in the material box 9 can be evenly mixed. As Figures 1 - 5 shown, it includes a control module 1. A driving module 2 is arranged on the left side of the control module 1. A lifting module 3 is arranged on the side of the driving module 2. A quick installation module 4 is arranged at the end of the driving module 2. A cleaning module 5 is arranged on the surface of the quick installation module 4. An anti-falling module 6 is arranged on the side of the driving module 2. The driving module 2 includes a connecting shaft 7, and a pulley 16 is sleeved and connected on the surface of the connecting shaft 7. A bottom plate 8 is fixedly connected between the control module 1 and the quick installation module 4. A material box 9 is bolted on the upper surface of the bottom plate 8. The inside of the material box 9 is connected with a mixing blade 18 through a rotating mechanism. A box cover 10 is movably arranged on the upper surface of the material box 9. A vertical plate 11 is fixedly connected to the upper surface of the bottom plate 8. A rotating shaft 12 is rotatably arranged inside the vertical plate 11. The other side of the pulley 16 is sleeved and connected to the surface of the rotating shaft 12. The end of the rotating shaft 12 is fixedly connected with a first bevel gear 13.

[0040] The rotating mechanism includes a long pin 14 rotatably arranged inside the material box 9, and a second bevel gear 15 is fixedly connected to the end of the long pin 14, and the second bevel gear 15 is meshed with the first bevel gear 13. The long pins 14 are symmetrically distributed on both sides of the material box 9, and a mixing blade 18 is fixedly connected to the surface of the long pin 14.

[0041] During operation, the control module 1 drives the drive module 2 to work. At the same time, the lifting module 3 enables the robot to have better flexibility. In addition, the quick-installation module 4 is used to quickly assemble the cleaning module 5, and the cleaning module 5 cleans the required positions. The anti-falling module 6 ensures the stability of the robot's work. During the movement of the robot, the drive module 2 drives the connecting shaft 7 to rotate. When the connecting shaft 7 rotates, the belt pulley 16 drives the rotating shaft 12 to rotate inside the vertical plate 11. When the rotating shaft 12 rotates, the first bevel gear 13 and the second bevel gear 15 at the end drive the long pin 14 to rotate inside the material box 9. When the long pin 14 rotates, it drives the mixing blade 18 to rotate. At this time, the mixing blade 18 plays a role in mixing the materials inside the material box 9, facilitating subsequent cleaning work.

[0042] Embodiment 2:

[0043] Different from Embodiment 1, the arranged inner rod 20 and fixed plate 21 play a role in assisting stirring and improve work efficiency. As Figures 4 - 7 shown, the inside of the material box 9 is connected with a fixed plate 21 through a reciprocating mechanism. The reciprocating mechanism includes a limit rod 24 fixedly connected to the surface of the material box 9, and an outer connecting plate 22 is sleeved on the surface of the limit rod 24. A rack 25 is fixedly connected to the surface of the outer connecting plate 22. The top view of the limit rod 24 is an inverted "U" shape. A cam 19 corresponding to the outer connecting plate 22 is fixedly connected to the end of the long pin 14. An inner rod 20 is rotatably arranged inside the material box 9, and a connecting gear 23 meshed with the rack 25 is fixedly connected to the surface of the inner rod 20. A connecting spring 26 that plays an elastic reset role is fixedly connected to the surface of the outer connecting plate 22, and the other side of the connecting spring 26 is fixedly connected to the inner wall of the limit rod 24. The fixed plate 21 is fixedly connected to the surface of the inner rod 20, and the fixed plates 21 are equally angularly distributed on the surface of the inner rod 20. Through holes 27 are equally spaced on the surface of the fixed plate 21.

[0044] When the long pin 14 rotates, the long pin 14 drives the cam 19 to rotate synchronously. Then, the cam 19 intermittently contacts the external plate 22. When the cam 19 pushes the external plate 22, the external plate 22 drives the rack 25 to move. At this time, under the action of the limit rod 24, the external plate 22 moves in the direction of squeezing the connecting spring 26. When the cam 19 continues to rotate until it no longer contacts the external plate 22, the external plate 22 returns to its original position under the action of the connecting spring 26. Repeating the above process, the external plate 22 drives the rack 25 to perform a reciprocating linear motion in the horizontal direction. When the rack 25 moves, it drives the inner rod 20 to rotate reciprocally inside the material box 9 through the connecting gear 23. At this time, the inner rod 20 drives the fixed plate 21 to move synchronously. Thus, the materials inside the material box 9 can be better mixed, optimizing the mixing effect. At the same time, through holes 27 are equidistantly distributed on the surface of the fixed plate 21, enabling the materials to move and exchange better, improving the working efficiency.

[0045] Embodiment 3:

[0046] Different from Embodiment 2, through the arranged spray head assembly 31, a cleaning agent can be sprayed on the air duct. In addition, a swinging mechanism is also arranged to make the spray head assembly 31 in a swinging state, expanding the working range of the spray head assembly 31. As Figures 8 - 10 shown, the upper surface of the bottom plate 8 is connected with a spray head assembly 31 through a swinging mechanism. A vertical plate 28 is fixedly connected to the upper surface of the bottom plate 8, and a cross bar 30 is rotatably arranged inside the vertical plate 28. The swinging mechanism includes an auxiliary plate 33 fixedly connected to the surface of the cross bar 30, and a first magnet 34 is fixedly connected to the upper surface of the auxiliary plate 33 at equal intervals. The spray head assembly 31 and the material box 9 are connected through an external hose. A movable block 35 is movably connected to the surface of the rotating shaft 12 through a bidirectional thread, and a second magnet 36 is fixedly connected to the lower surface of the movable block 35. And the magnetic pole on the lower surface of the second magnet 36 is the same as the magnetic pole on the upper surface of the first magnet 34. A limiting strip 37 penetrating through the inside of the movable block 35 is fixedly connected to the inner wall of the vertical plate 11, and a top rod 29 is fixedly connected to the upper surface of the bottom plate 8.

[0047] During operation, the robot sprays the cleaning agent inside the material box 9 through the nozzle assembly 31, facilitating the subsequent cleaning work of the cleaning module 5 and improving work efficiency. The rotating shaft 12 and the movable block 35 are connected by a double-thread. Thus, when the rotating shaft 12 rotates, the rotating shaft 12 drives the movable block 35 to perform a reciprocating linear motion in the horizontal direction through the limiting strip 37. At this time, the first magnet 34 will intermittently approach the second magnet 36. When the first magnet 34 approaches the second magnet 36, the auxiliary plate 33 drives the cross bar 30 to rotate inside the vertical plate 28 under the action of the mutually repulsive magnetic force. When the first magnet 34 moves away from the second magnet 36, the auxiliary plate 33 rotates back under its own gravity. At this time, the cross bar 30 rotates back. Repeating the above process, the cross bar 30 and the nozzle assembly 31 are in a swinging state. Thus, the working range of the nozzle assembly 31 increases and the work efficiency is improved. When the nozzle assembly 31 swings, the ejector rod 29 plays a role in limiting the rotation angle of the nozzle assembly 31, ensuring stability.

[0048] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
