Description

Technical Field

[0002] With the rapid development of industry and transportation, airfoil structures are prone to being affected by environmental and biological factors during long-term use, leading to problems such as surface corrosion, rust, and biological attachment. This not only increases the operating resistance but also raises energy consumption.

[0003] Although rust spots and biological attachment can be controlled to a certain extent by spraying anti-fouling coatings currently, their potential environmental toxicity cannot be ignored. Additionally, due to the large volume of airfoil structures, manual or traditional mechanical cleaning equipment often fails to effectively adapt to the complex shape of airfoil surfaces, resulting in low cleaning efficiency, unnecessary wear on the surface, increased maintenance costs, and potential safety risks.

[0004] Therefore, there is an urgent need to develop an efficient and environmentally friendly wear-resistant cleaning device for airfoil surfaces, which should be able to adapt to diverse geometric shapes, effectively remove surface dirt, minimize wear on airfoil surfaces to the greatest extent, enhance wear resistance, thereby improving cleaning efficiency and ensuring the safety of operators and the environment.

The spring provides elastic force, and the diaphragm is used to prevent air leakage.

[0038] The non-smooth petal rubber suction cup 139 is fixed to the lower part of the base by the first screw 138. Its unique petal shape expands the contact area, enhances friction and suction force, ensuring firmness. At the same time, several pits are designed on the surface of the suction cup to form a non-smooth structure, improving wear resistance and protecting the airfoil surface.

[0041] In this embodiment, the first transmission shaft 110 is positioned by a first bearing 17 and a second bearing 19. The first end cover 111 is fixed by a second screw 18. The large gear 16 on the first transmission shaft 110 meshes with the first gear 116 on the stepped shaft 115. The stepped shaft 115 is positioned by a third bearing 114 and a fifth bearing 122. The lower end of the stepped shaft is fixed by a bearing end cover 123, and the upper end is fixed by a third screw 113 and a second end cover 117. The small gear 112 on the stepped shaft 115 meshes with the second gear 124 on the motor shaft. The motor shaft 120 is positioned by a fifth bearing 122. The upper end of the motor shaft is fixed by a fourth screw 118 and a third end cover 119.

The cylindrical body 132 is bonded to the first ball screw platform 128. The limit block 129 is fixed by a fifth screw 130 to limit the movement of the cylindrical body 132 within a certain range. The moving block 131 is assembled to the end of the first transmission shaft 110 for fixation. The bottom of the cylindrical body 132 is closely bonded to the base 133. Through the above assembly, when the first motor rotates forward, the cylindrical body 132 extends downward; when the first motor rotates reversely, the cylindrical body 132 retracts upward, realizing the telescopic function.

[0042] In this embodiment, the propulsion units are installed at the left and right ends of the entire device and are respectively connected to the first moving leg 2 and the second moving leg 4. The first moving leg 2 and the second moving leg 4 are respectively assembled on the left and right sides of the device. The first fixed leg 1 and the second fixed leg 3 are respectively installed on the left and right sides of the device through studs, and the multiple air pumps are evenly distributed on the fixed legs and the moving legs. The propulsion unit includes a second driving device, a second ball screw platform 28, a fourth gripper 21, a second coupling 23, a first L-shaped connecting body 27, a first stud 29, and a first U-shaped body 211. The second driving device is connected to the second ball screw platform 28. The second driving device includes a second motor 22 and a second transmission shaft 24.

[0043] The second motor 22 is fixed on the clamping plate 5 by the fourth gripper 21. The second coupling 23 connects the motor shaft with the second transmission shaft 24. The second transmission shaft 24 is positioned by the sixth bearing 25 and the seventh bearing 210 assembled at the left and right ends of the first U-shaped body 211. The second transmission shaft 24 is assembled with the second ball screw platform 28 through the sixth screw 26. The first L-shaped connecting body 27 connects the second ball screw platform 28 with the telescopic unit through the first stud 29. When the second motor rotates forward, the telescopic unit moves forward; when the second motor rotates in reverse, the telescopic unit moves backward.

[0044] As Figure 1 , Figure 3 , Figure 4A and Figure 4B shown, in this embodiment, the cutting mechanism is located in the middle and lower part of the device, and includes a third driving device, a sickle, a fifth gripper 31, a third coupling 33, a second stud 36, a sixth gripper 310, a square frame 312, a second L-shaped connecting body 313, a third stud 314, a third ball screw platform 315 and a third U-shaped body 317. The third driving device includes a third transmission shaft 34, a third motor 32 and a fourth motor 311, and the sickle is an annular sickle 38.

[0045] The third motor 32 is fixed on the bottom plate of the second moving leg 4 by the fifth gripper 31. The third coupling 33 connects the motor shaft with the third transmission shaft 34. The third transmission shaft 34 is positioned by the eighth bearing 35 and the ninth bearing 316 assembled at the left and right ends of the third U-shaped body 317. The third transmission shaft 34 is assembled with the third ball screw platform 315. The second L-shaped connecting body 313 connects the third ball screw platform 315 with the square frame 312 through the third stud 314. The fourth motor 311 is fixed in the square frame 312 by the sixth gripper 310, and the fourth motor 311 is sealed by the seventh screw 37 and the end cover. The motor shaft is fastened to the stud through the third bolt 39. The annular sickle 38 is arranged along the stud and is strengthened and fixed by nuts, and an axial design in the form of a stud is adopted, which is convenient for installation and disassembly. At the same time, the device is equipped with a plurality of annular sickles with different sizes for stacking on the shaft to increase the number of blade layers and improve the cutting efficiency. When the fourth motor 311 is turned on, the annular sickle starts to rotate to clean the dirt. At the same time, when the third motor 32 is turned on, when the third motor 32 rotates forward, the cutting mechanism moves to the left; when the third motor 32 rotates in reverse, the cutting mechanism moves to the right.

[0046] As Figure 5A , Figure 5B and Figure 6As shown in the figure, in this embodiment, the adsorption mechanism has two modes, namely the flat mode and the concave-convex mode. When the airfoil surface is relatively flat, the flat mode is turned on. At this time, the servo 141 controls the support plate 144 to rotate outwards, so that the connecting body 134 can be supported and maintain a certain height.

[0047] When the airfoil surface is uneven, the concave-convex mode is turned on. At this time, the servo 141 controls the support plate 144 to retract inwards, and the connecting body 134 is only supported by the spring 136. When there is a protrusion on the airfoil surface, the connecting body 134 will slide down a certain height at this time, and the sliding height is the distance between the protrusion and the horizontal surface. Since six non-smooth petal rubber suction cups 139 are distributed on the base and the force is evenly distributed, it can be adjusted automatically on the concave-convex surface, so that the whole device remains horizontal. This can make the adsorption mechanism fit the working surface better, effectively cope with different working surface environments, and improve the adsorption capacity of the whole device.

[0048] As Figure 7 shown in the figure, in this embodiment, the base 133 internally contains a pipeline structure, and connection ports are provided below each pipeline connection for the assembly of the connecting body 134. Six non-smooth petal rubber suction cups 139 are provided at the lower part, so that the force on the base is evenly distributed and the work is more stable.

[0049] The working process of an airfoil surface high-efficiency wear-resistant cleaning device according to an embodiment of the present application is specifically as follows:

[0050] In the first step, the device is moved to the airfoil surface, and the four air pumps of the fixed legs 1, 3 and the moving legs 2, 4 are turned on. Due to the suction force, the whole device will be adsorbed on the airfoil surface. At this time, the fixed legs and the moving legs of the whole device are in the extended state.

[0051] In the second step, the two air pumps of the first fixed leg 1 and the second fixed leg 3 are turned off, and then the two motors of the telescopic units on the first fixed leg 1 and the second fixed leg 3 are started. At this time, the first fixed leg 1 and the second fixed leg 3 contract. Then, the two motors of the propulsion units connected to the first moving leg 2 and the second moving leg 4 are started synchronously, and the ball screw starts to move, driving the whole device to move forward. Then, the two motors of the telescopic units on the first fixed leg 1 and the second fixed leg 3 are started again to extend the first fixed leg 1 and the second fixed leg 3 until they reach the airfoil surface. At this time, the two air pumps of the first fixed leg 1 and the second fixed leg 3 are turned on. The fixed legs and the moving legs are in the extended state and adsorbed on the airfoil surface. At this time, compared with the initial position, the whole device has moved forward a certain distance.

[0052] In the third step, turn off the air pumps of the first moving leg 2 and the second moving leg 4, and then start the two motors of the telescopic units on the first moving leg 2 and the second moving leg 4. At this time, the first moving leg 2 and the second moving leg 4 contract synchronously. Then, synchronously turn on the two motors of the propulsion units connected to the first moving leg 2 and the second moving leg 4. At this time, the first moving leg 2 and the second moving leg 4 move forward synchronously. Then, start the two motors of the telescopic units on the first moving leg 2 and the second moving leg 4 again to extend the first moving leg 2 and the second moving leg 4 to the airfoil surface. At this time, turn on the two air pumps of the first moving leg 2 and the second moving leg 4. All four legs are in the extended state and adsorbed on the airfoil surface. At this time, the first fixed leg 1, the second fixed leg 3, the first moving leg 2, and the second moving leg 4 return to the initial position relative to the entire device.

[0053] Repeat the second and third steps to achieve the moving function of the device.

[0054] In the fourth step, turn on the third motor 32 of the cutting mechanism. By the forward and reverse rotation of the third motor 32, drive the ring scythe 38 to move left and right. At this time, turn on the fourth motor 311 to start the cutting and cleaning work. At the same time, through the operation of the moving mechanism, the height of the entire device can be adjusted according to different airfoils, so as to realize the up, down, front, and back movement of the cutting mechanism. In summary, the three-degree-of-freedom work of the cutting mechanism in the up, down, left, right, front, and back directions can be achieved, and the entire device can work on the airfoil surface.

Although the utility model has been described in detail with reference to the foregoing examples, for those skilled in the art, they can still modify the technical solutions described in the foregoing examples, or perform equivalent replacements for some of the technical features.
