Description

Technical Field

[0001] The present invention relates to the technical field of component detection equipment, and particularly to a magnetic particle flaw detector for aircraft components. Background Technique

[0002] After the flaw detector is ready, the test piece is inserted between the two poles of the electromagnet of the machine, the electromagnet is turned on, and the magnetic particle suspension is applied to the test piece. When there are defects inside the workpiece, such as non-ferromagnetic substances like cracks, inclusions, and pores, its magnetic resistance is very large and its magnetic permeability is low. Since the magnetic particles in the suspension contain pigments that can fluoresce under ultraviolet light, the lines precipitated by the pigments can be observed more clearly under the ultraviolet lamp in the dark, thus realizing the magnetic particle flaw detection process for the workpiece.

[0003] Among them, the suspension contains fluorescent pigments and magnetic substances. Such heavy metal substances will precipitate in the suspension. When the equipment detects aircraft components, the components contained in the externally sprayed suspension are uneven, resulting in errors in the flaw detection effect of the equipment. For the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a magnetic particle flaw detector for aircraft components, including a bracket. Inside the inner wall of the bracket, a collection box is fixedly connected, and inside the inner wall of the collection box, an energized track is fixedly connected;

[0005] A detection mechanism, the detection mechanism includes an aircraft part, a fixing frame one for clamping and restricting the aircraft part, an electromagnetic block, a blocking rod, and a spraying assembly for spraying the magnetic suspension solution;

[0006] The side wall of the collection box is fixedly connected to the side wall of the fixing frame one. Inside the inner wall of the energized track, the electromagnetic block is slidably connected. Inside the inner wall of the collection box, the outer wall of the blocking rod is fixedly connected. Inside the through hole inner wall of the electromagnetic block, the outer wall of the blocking rod is slidably connected. The outer wall of the energized track is in close contact with the outer wall of the aircraft part.

[0007] Preferably, the spraying assembly includes a storage box fixedly connected to one end of the fixing frame one away from the collection box. The bottom of the storage box is rotatably connected to a rotating pipe. The bottom of the fixing frame one is fixedly connected to a collection pipe. The bottom of the collection pipe is connected through a nozzle. Five louvers are fixedly connected to the side wall of the rotating pipe. Before use, the bracket is installed at the required position, then the aircraft part is placed on top of the energized track, and the two electromagnetic blocks are moved towards the side wall of the aircraft part and ensured not to touch. Then, the power supply of the electromagnetic block is connected through the energized track.

[0008] Preferably, the spraying assembly further includes an arc-shaped baffle fixedly connected to one end of the five louver blades away from the rotating pipe. An arc-shaped spring is fixedly connected to the side wall of the arc-shaped baffle, and the end of the arc-shaped spring away from the arc-shaped baffle is fixedly connected to the side wall of the rotating pipe. A second fixing frame is fixedly connected to the inner wall of the storage tank, and a motor is fixedly connected to the top of the second fixing frame.

[0009] Preferably, the spraying assembly further includes a driving pipe fixedly connected to the output shaft of the motor. The end of the driving pipe away from the motor is fixedly connected to an installation box. Six stirring fan blades are fixedly connected to the outer wall of the installation box. The end of the stirring fan blade away from the installation box is fixedly connected to the inner wall of the rotating pipe. A sliding frame is slidably connected to the outer wall of the stirring fan blade. A counterweight is fixedly connected to the bottom of the sliding frame. A push rod is fixedly connected to the bottom of the counterweight. An adjusting assembly is fixedly connected to the inner wall of the installation box. A blocking assembly is fixedly connected to the side wall of the arc-shaped baffle. A limiting assembly is fixedly connected to the inner wall of the arc-shaped baffle. The motor drives the stirring fan blade to rotate through the driving pipe and the installation box, stirring the suspension on the inner wall of the storage tank and the top of the arc-shaped baffle to prevent the suspension from precipitating. As the rotation speed of the stirring fan blade and the rotating pipe increases, the centrifugal force received by the sliding frame and the counterweight increases. At this time, the sliding frame will drive the push rod to contact the inner wall of the arc-shaped baffle, forcing the arc-shaped baffle to rotate outward with the louver blade as the center. During this process, the arc-shaped baffle is simultaneously squeezed by the liquid inside the storage tank, forcing the five arc-shaped baffles to swing outward with the corresponding louver blades as the center. As the distance between the arc-shaped baffles increases, the suspension inside the storage tank will fall downward through the gaps between the arc-shaped baffles and fall to the bottom of the collection pipe, and finally be sprayed on the top of the aircraft parts through the nozzle. Through the application of the above components, the data error caused by the precipitation of the suspension during equipment detection is reduced.

[0010] Preferably, the adjusting assembly includes five first hydraulic telescopic tubes penetrating and connecting to the side wall of the storage tank. One end of the five first hydraulic telescopic tubes away from the installation box is fixedly connected to the side wall of the counterweight block. One end of the first hydraulic telescopic tube away from the counterweight block is penetrated and connected with an L-shaped tube. A piston block one is slidably connected to the inner wall of the L-shaped tube away from the first hydraulic telescopic tube. A pulling rod is fixedly connected to the top of the piston block one. One end of the five pulling rods away from the piston block one is fixedly connected to a fixing ring. A first spring is fixedly connected to the top of the fixing ring. One end of the first spring away from the fixing ring is fixedly connected to a fixing disk. The side wall of the fixing disk is fixedly connected to the inner wall of the driving tube. By utilizing the characteristic that the centrifugal force drives the sliding frame and the counterweight block to move outward, an adjusting assembly is arranged inside the device. When the counterweight block moves outward, the outward moving counterweight block will drive one end of the first hydraulic telescopic tube to move outward. The extended first hydraulic telescopic tube will extract the liquid inside the L-shaped tube, forcing the piston block one to slide downward along the inner wall of the L-shaped tube. The five downward moving piston blocks one will drive the fixing ring to move downward synchronously through the pulling rods. During this process, the fixing ring will control the speed and length of the downward movement of the five piston blocks one, indirectly controlling the length of the outward extension of the five first hydraulic telescopic tubes, and avoiding the rotation center of the stirring fan blade from shifting due to the influence of sediment, resulting in different positions of the corresponding counterweight blocks relative to the stirring fan blades, which affects the stirring efficiency of the stirring fan blade.

[0011] Preferably, the blocking assembly includes closing grooves opened at both ends of the arc-shaped baffle. An expansion airbag is fixedly connected to the inner wall of the closing groove on the left side of the arc-shaped baffle. An arc-shaped air pressure tube is fixedly connected to the side wall of the rotating tube. A piston block two is slidably connected to the inner wall of the arc-shaped air pressure tube. An arc-shaped tube is fixedly connected to the side wall of the piston block two. A circulation port is opened on the side wall of the arc-shaped tube. While controlling the outward movement speed of the multiple first hydraulic telescopic tubes through the fixing ring, when a large piece of sediment adheres to the outer wall of one of the stirring fan blades, the corresponding stirring fan blade will be blocked and unable to move. The blocked counterweight block will limit the extension of the corresponding first hydraulic telescopic tube. At this time, the remaining counterweight blocks will also be unable to move outward. The centrifugal force borne by the remaining four counterweight blocks will be transmitted to the blocked first hydraulic telescopic tube through the corresponding piston block one, pulling rod, and fixing ring. The blocked first hydraulic telescopic tube will increase the outward thrust to remove the large impurities remaining on the outer wall of the stirring fan blade.

[0012] Preferably, the plugging assembly further includes a first air pressure box fixedly connected to the side wall of the arc-shaped baffle. A transmission square pipe is connected through the side wall of the first air pressure box. One end of the transmission square pipe away from the first air pressure box is fixedly connected to a second air pressure box. An air inlet is provided on the side wall of the second air pressure box. One end of the air inlet away from the second air pressure box is connected through the inner wall of the expansion airbag. By using the characteristic that the above-mentioned arc-shaped baffle rotates outward under the extrusion of the counterweight and the suspension liquid, a plugging assembly and a limiting assembly are arranged inside the device. When the device finishes spraying, the motor stops running. As the centrifugal force disappears, the first spring drives the fixed ring to reset, forcing the first hydraulic telescopic pipe to drive the corresponding counterweight to reset synchronously. As the liquid in the storage tank decreases, the arc-shaped baffle gradually resets under the push of the arc-shaped spring. At this time, the second piston block will slide along the inner wall of the arc-shaped air pressure pipe, presenting a state as shown in Figure 8 . During the sliding process of the second piston block, the gas at the bottom of the second piston block passes through the communication port and the arc-shaped pipe and is transmitted into the first air pressure box. This sliding block will block the transmission square pipe and limit the gas from passing through the transmission square pipe.

[0013] Preferably, the limiting assembly includes a sliding block slidably connected to the inner wall of the transmission square pipe. A first through-hole groove is provided on the side wall of the sliding block. An air pressure groove is provided on the inner wall of the arc-shaped baffle. A first hydraulic pipe is fixedly connected to the inner wall of the air pressure groove. A third piston block is slidably connected to the inner wall of the first hydraulic pipe. A third spring is fixedly connected to the bottom of the third piston block. A second hydraulic telescopic rod is connected through the side wall of the first hydraulic pipe. A buffer assembly is fixedly connected to one end of the sliding block close to the first hydraulic pipe. As the arc-shaped baffle gradually resets under the push of the arc-shaped spring, several arc-shaped baffles approach and closely adhere to each other. At this time, the top of the third piston block will contact the bottom of the rotating pipe. At this time, the third piston block compresses the liquid inside the first hydraulic pipe into the second hydraulic telescopic rod, causing the second hydraulic telescopic rod to push the sliding block to slide outward along the inner wall of the transmission square pipe. At this time, the first through-hole groove coincides with the inner wall of the transmission square pipe, enabling the gas inside the first air pressure box to enter the second air pressure box through the gap between the transmission square pipe and the first through-hole groove. The gas inside the second air pressure box is transmitted into the expansion airbag through the air inlet. At this time, multiple arc-shaped baffles are mutually attached. At this time, the expanded expansion airbag will enter the closed groove between adjacent arc-shaped baffles. Through the application of the above components, it is ensured that when the device is not running, the expanded expansion airbag can fill the gap between the arc-shaped baffles, avoiding the phenomenon of liquid leakage of the suspension liquid at the top.

[0014] Preferably, the buffer assembly includes a second hydraulic pipe fixedly connected to one end of the sliding block close to the second hydraulic telescopic rod. A fourth piston block is slidably connected to the inner wall of the second hydraulic pipe. A support rod is fixedly connected to the side wall of the fourth piston block. A second through-hole groove is provided on the side wall of the fourth piston block. A right-angle groove is provided on the inner wall of the second through-hole groove. A rotating plate is rotatably connected to the inner wall of the right-angle groove.

[0015] Preferably, one end of the support rod away from the piston block four is fixedly connected to the side wall of the first hydraulic pipe, one end of the second hydraulic telescopic rod away from the first hydraulic pipe is fixedly connected to the side wall of the sliding block, one end of the third spring away from the piston block three is fixedly connected to the bottom of the air pressure groove, one end of the arc-shaped pipe away from the piston block two is connected to the side wall of the first air pressure box in a penetrating manner, and the outer wall of the L-shaped pipe is fixedly connected to the inner wall of the installation box. By utilizing the characteristic that the second hydraulic telescopic rod pushes the sliding block to move outward, a buffer assembly is arranged inside the device. As the sliding block moves outward, the distance between the first hydraulic pipe and the sliding block increases, presenting a state as shown in Figure 11 . At this time, the support rod will drive the piston block four to horizontally move to the left along the inner wall of the second hydraulic pipe, and at this time, the rotating plate will swing, presenting the state of G in Figure 11 . The gap between the rotating plate and the second through-hole groove expands. Therefore, the piston block four slides along the second hydraulic pipe at a relatively fast speed. When the device runs again, the arc-shaped baffle swings outward, forcing the piston block two to draw the gas inside the first air pressure box through the spring vent and the arc-shaped pipe. When the pressure on the top of the piston block three is lost, the third spring releases mechanical power, forcing the second hydraulic telescopic rod to drive the sliding block to reset. The piston block four will move to the right along the inner wall of the second hydraulic pipe, and at this time, the rotating plate will tilt upward, presenting a state as shown in Figure 12 . The gap between the rotating plate and the second through-hole groove is reduced, and the reset speed of the second hydraulic telescopic rod is reduced. Through the application of the above components, the reset speed of the sliding block is slowed down, preventing the sliding block from blocking the transmission square pipe too quickly, making it difficult for the piston block two to draw the gas inside the first air pressure box, the second air pressure box, and the expansion air bag, and affecting the efficiency of the arc-shaped baffle opening outward.

[0016] The present invention has the following beneficial effects:

[0017] (1) In view of the problem of suspension precipitation in the present invention, a spraying component is provided inside the device. Before use, the bracket is installed at the required position, and then the aircraft part is placed on top of the energized track. Then, the two electromagnetic blocks are moved towards the side wall of the aircraft part, ensuring no contact. Subsequently, the power supply of the electromagnetic blocks is connected through the energized track, and the power supply of the motor is also connected. The motor drives the stirring fan blades to rotate through the drive tube and the installation box, stirring the suspension on the inner wall of the storage tank and the top of the arc-shaped baffle, avoiding the precipitation of the suspension. As the rotation speed of the stirring fan blades and the rotating tube increases, the centrifugal force received by the sliding frame and the counterweight increases. At this time, the sliding frame will drive the push rod to contact the inner wall of the arc-shaped baffle, forcing the arc-shaped baffle to rotate outward with the shutter as the center. During this process, the arc-shaped baffle is simultaneously squeezed by the liquid inside the storage tank, forcing the five arc-shaped baffles to swing outward with the corresponding shutters as the center. As the distance between the arc-shaped baffles increases, the suspension inside the storage tank will fall downward through the gaps between the arc-shaped baffles and fall to the bottom of the collection tube, and finally be sprayed on the top of the aircraft part through the nozzle. Through the application of the above components, the data error caused by the precipitation of the suspension during equipment detection is reduced.

[0018] (2) Taking advantage of the characteristic that the centrifugal force drives the sliding frame and the counterweight to move outward in the present invention, an adjustment component is provided inside the device. When the counterweight moves outward, the outward-moving counterweight will drive one end of the hydraulic telescopic tube 1 to move outward. The extended hydraulic telescopic tube 1 will extract the liquid inside the L-shaped tube, forcing the piston block 1 to slide downward along the inner wall of the L-shaped tube. The five downward-moving piston blocks 1 drive the fixed ring to move downward synchronously through the pulling rod. During this process, the fixed ring will control the speed and length of the downward movement of the five piston blocks 1, indirectly controlling the extended length of the five hydraulic telescopic tubes 1, avoiding the rotation center of the stirring fan blades from shifting due to the influence of sediment, resulting in different positions of the counterweights corresponding to the stirring fan blades and affecting the stirring efficiency of the stirring fan blades. In addition, while controlling the outward movement speed of the multiple hydraulic telescopic tubes 1 through the fixed ring, when a large piece of sediment adheres to the outer wall of one of the stirring fan blades, the corresponding stirring fan blade will be blocked and unable to move. The blocked counterweight will limit the corresponding hydraulic telescopic tube 1 from extending. At this time, the remaining counterweights cannot move outward either. The centrifugal force borne by the remaining four counterweights will be transmitted to the blocked hydraulic telescopic tube 1 through the corresponding piston block 1, pulling rod, and fixed ring. The blocked hydraulic telescopic tube 1 will increase the outward thrust to remove the large impurities remaining on the outer wall of the stirring fan blade.

[0019] (3) By taking advantage of the feature that the above-mentioned arc-shaped baffle rotates outward under the extrusion of the counterweight and the suspension liquid, a plugging component and a limiting component are arranged inside the device. When the device finishes spraying, the motor stops running. As the centrifugal force disappears, the first spring drives the fixed ring to reset, forcing the first hydraulic telescopic tube to drive the corresponding counterweight to reset synchronously. As the liquid inside the storage tank decreases, the arc-shaped baffle gradually resets under the push of the arc-shaped spring. At this time, the second piston block will slide along the inner wall of the arc-shaped air pressure tube, presenting a state as shown in Figure 8 . During the sliding process of the second piston block, the gas at the bottom of the second piston block is transmitted to the inside of the first air pressure tank through the communication port and the arc-shaped tube. This sliding block will block the transmission square tube and restrict the gas from passing through the transmission square tube. As the arc-shaped baffle gradually resets under the push of the arc-shaped spring, several arc-shaped baffles approach and closely adhere to each other. At this time, the top of the third piston block will contact the bottom of the rotating tube. At this time, the third piston block compresses the liquid inside the first hydraulic tube into the second hydraulic telescopic rod, causing the second hydraulic telescopic rod to push the sliding block to slide outward along the inner wall of the transmission square tube. At this time, the first through-hole groove will coincide with the inner wall of the transmission square tube, enabling the gas inside the first air pressure tank to enter the second air pressure tank through the gap between the transmission square tube and the first through-hole groove. And the gas inside the second air pressure tank is transmitted to the inside of the expansion airbag through the air inlet. At this time, multiple arc-shaped baffles are mutually attached. At this time, the inflated expansion airbag will enter the closed groove between adjacent arc-shaped baffles. Through the application of the above components, it is ensured that when each arc-shaped baffle is not operating, the inflated expansion airbag can fill the gap between the arc-shaped baffles, avoiding the phenomenon of liquid leakage of the suspension liquid at the top.

[0020] (4) By taking advantage of the feature that the second hydraulic telescopic rod pushes the sliding block to move outward, a buffer component is arranged inside the device. As the sliding block moves outward, the distance between the first hydraulic tube and the sliding block increases, presenting a state as shown in Figure 11 . At this time, the support rod will drive the fourth piston block to horizontally move to the left along the inner wall of the second hydraulic tube. At this time, the rotating plate will swing, presenting the state of G in Figure 11 . The gap between the rotating plate and the second through-hole groove expands. Therefore, the fourth piston block slides along the second hydraulic tube at a relatively fast speed. When the device runs again, the arc-shaped baffle swings outward, forcing the second piston block to extract the gas inside the first air pressure tank through the spring communication port and the arc-shaped tube. When the pressure on the top of the third piston block is lost, the third spring releases mechanical power, forcing the second hydraulic telescopic rod to drive the sliding block to reset. The fourth piston block will move to the right along the inner wall of the second hydraulic tube. At this time, the rotating plate will tilt upward, presenting a state as shown in Figure 12 . The gap between the rotating plate and the second through-hole groove is reduced, reducing the reset speed of the second hydraulic telescopic rod. Through the application of the above components, the reset speed of the sliding block is slowed down, avoiding the sliding block from blocking the transmission square tube too quickly, which makes it difficult for the second piston block to extract the gas inside the first air pressure tank, the second air pressure tank, and the expansion airbag, affecting the efficiency of the arc-shaped baffle to open outward.

[0039] The side wall of the collection box 11 is fixedly connected to the side wall of the first fixing bracket 22. The electromagnetic block 23 is slidably connected to the inner wall of the energized track 12. The outer wall of the collection box 11 is fixedly connected to the outer wall of the blocking rod 24. The outer wall of the blocking rod 24 is slidably connected to the inner wall of the through-hole of the electromagnetic block 23. The outer wall of the energized track 12 is in close contact with the outer wall of the aircraft part 21.

[0040] The spraying assembly 3 includes a storage tank 31 fixedly connected to one end of the first fixing frame 22 away from the collection tank 11. A rotating pipe 32 is rotatably connected to the bottom of the storage tank 31. A collection pipe 33 is fixedly connected to the bottom of the first fixing frame 22. The bottom of the collection pipe 33 is connected to a nozzle 34 in a penetrating manner. Five louvers 35 are fixedly connected to the side wall of the rotating pipe 32. Before use, the bracket 1 is installed at the required position. Subsequently, the aircraft part 21 is placed on the top of the energized track 12, and the two electromagnets 23 are moved towards the side wall of the aircraft part 21 and ensured not to touch. Subsequently, the power supply of the electromagnets 23 is turned on through the energized track 12.

[0041] The spraying assembly 3 further includes an arc-shaped baffle 36 fixedly connected to one end of the five louvers 35 away from the rotating pipe 32. An arc-shaped spring 37 is fixedly connected to the side wall of the arc-shaped baffle 36. One end of the arc-shaped spring 37 away from the arc-shaped baffle 36 is fixedly connected to the side wall of the rotating pipe 32. A second fixing frame 38 is fixedly connected to the inner wall of the storage tank 31. A motor 39 is fixedly connected to the top of the second fixing frame 38.

[0042] The spraying assembly 3 further includes a driving pipe 310 fixedly connected to the output shaft of the motor 39. One end of the driving pipe 310 away from the motor 39 is fixedly connected to an installation box 311. Six stirring fan blades 312 are fixedly connected to the outer wall of the installation box 311. One end of the stirring fan blades 312 away from the installation box 311 is fixedly connected to the inner wall of the rotating pipe 32. A sliding frame 313 is slidably connected to the outer wall of the stirring fan blades 312. A counterweight 314 is fixedly connected to the bottom of the sliding frame 313.

A blocking assembly 5 is fixedly connected to the side wall of the arc-shaped baffle 36. A limiting assembly 6 is fixedly connected to the inner wall of the arc-shaped baffle 36. The motor 39 drives the stirring fan blades 312 to rotate through the driving pipe 310 and the installation box 311, stirring the suspension on the inner wall of the storage tank 31 and the top of the arc-shaped baffle 36 to prevent the suspension from precipitating. As the rotation speed of the stirring fan blades 312 and the rotating pipe 32 increases, the centrifugal force received by the sliding frame 313 and the counterweight 314 increases. At this time, the sliding frame 313 will drive the push rod 315 to contact the inner wall of the arc-shaped baffle 36, forcing the arc-shaped baffle 36 to rotate outward with the louvers 35 as the center. During this process, the arc-shaped baffle 36 is simultaneously squeezed by the liquid inside the storage tank 31, forcing the five arc-shaped baffles 36 to swing outward with the corresponding louvers 35 as the center. As the distance between the arc-shaped baffles 36 increases, the suspension inside the storage tank 31 will fall downward through the gaps between the arc-shaped baffles 36 and fall into the bottom of the collection pipe 33, and finally be sprayed on the top of the aircraft part 21 through the nozzle 34. Through the application of the above components, the data error caused by the precipitation of the suspension during equipment detection is reduced.

[0043] Example two, please refer toFigure 7 - Figure 12 In the present invention, a magnetic particle flaw detector for aircraft parts is provided. On the basis of Embodiment 1, the adjusting assembly 4 includes five first hydraulic telescopic tubes 41 connected through the side wall of the storage tank 31. One end of the five first hydraulic telescopic tubes 41 away from the installation box 311 is fixedly connected to the side wall of the counterweight 314. One end of the first hydraulic telescopic tube 41 away from the counterweight 314 is connected with an L-shaped tube 42 through. A piston block 43 is slidably connected to the inner wall of the L-shaped tube 42 away from the first hydraulic telescopic tube 41. A pulling rod 44 is fixedly connected to the top of the piston block 43. One end of the five pulling rods 44 away from the piston block 43 is fixedly connected to a fixing ring 45. A first spring 46 is fixedly connected to the top of the fixing ring 45. One end of the first spring 46 away from the fixing ring 45 is fixedly connected to a fixing disc 47. The side wall of the fixing disc 47 is fixedly connected to the inner wall of the driving tube 310. By using the characteristic that the centrifugal force drives the sliding frame 313 and the counterweight 314 to move outwards, an adjusting assembly 4 is arranged inside the device. When the counterweight 314 moves outwards, the outer moving counterweight 314 will drive one end of the first hydraulic telescopic tube 41 to move outwards. The extended first hydraulic telescopic tube 41 will extract the liquid inside the L-shaped tube 42, forcing the piston block 43 to slide down along the inner wall of the L-shaped tube 42. The five descending piston blocks 43 drive the fixing ring 45 to move down synchronously through the pulling rods 44. During this process, the fixing ring 45 will control the speed and length of the five piston blocks 43 moving downwards, indirectly controlling the length of the five first hydraulic telescopic tubes 41 extending outwards, avoiding the influence of sediment, resulting in the counterweights 314 being in different positions corresponding to the stirring fan blades 312, causing the rotation center of gravity of the stirring fan blades 312 to shift and affecting the stirring efficiency of the stirring fan blades 312.

[0044] The blocking assembly 5 includes closing grooves 51 opened at both ends of the arc-shaped baffle 36. An expansion airbag 52 is fixedly connected to the inner wall of the closing groove 51 on the left side of the arc-shaped baffle 36. An arc-shaped air pressure tube 53 is fixedly connected to the side wall of the rotating tube 32. A piston block 54 is slidably connected to the inner wall of the arc-shaped air pressure tube 53. An arc-shaped tube 55 is fixedly connected to the side wall of the piston block 54. A circulation port 56 is opened on the side wall of the arc-shaped tube 55. While controlling the outward movement speed of the multiple first hydraulic telescopic tubes 41 through the fixing ring 45, when a large piece of sediment adheres to the outer wall of one of the stirring fan blades 312, the corresponding stirring fan blade 312 will be blocked and unable to move. The blocked counterweight 314 will limit the corresponding first hydraulic telescopic tube 41 from extending. At this time, the remaining counterweights 314 will also be unable to move outwards. The centrifugal force borne by the remaining four counterweights 314 will be transmitted to the blocked first hydraulic telescopic tube 41 through the corresponding piston block 43, pulling rod 44 and fixing ring 45. The blocked first hydraulic telescopic tube 41 will increase the outward thrust to remove the large impurities remaining on the outer wall of the stirring fan blade 312.

[0045] The plugging assembly 5 further includes a first air pressure box 57 fixedly connected to the side wall of the arc-shaped baffle 36. A transmission square pipe 58 is connected through the side wall of the first air pressure box 57. One end of the transmission square pipe 58 away from the first air pressure box 57 is fixedly connected to a second air pressure box 59. An air inlet 510 is opened on the side wall of the second air pressure box 59. One end of the air inlet 510 away from the second air pressure box 59 is connected through the inner wall of the expansion air bag 52. By using the characteristic that the above-mentioned arc-shaped baffle 36 rotates outward under the extrusion of the counterweight 314 and the suspension liquid, a plugging assembly 5 and a limiting assembly 6 are arranged inside the equipment. When the equipment finishes spraying, the motor 39 stops running. As the centrifugal force disappears, the first spring 46 drives the fixed ring 45 to reset, forcing the first hydraulic telescopic pipe 41 to drive the corresponding counterweight 314 to reset synchronously. As the liquid in the storage tank 31 decreases, the arc-shaped baffle 36 gradually resets under the push of the arc-shaped spring 37. At this time, the second piston block 54 will slide along the inner wall of the arc-shaped air pressure pipe 53, presenting a state as shown in Figure 8 . During the sliding process of the second piston block 54, the gas at the bottom of the second piston block 54 is transmitted to the inside of the first air pressure box 57 through the communication port 56 and the arc-shaped pipe 55. This sliding block 61 will block the transmission square pipe 58, restricting the gas from passing through the transmission square pipe 58.

[0046] The limiting assembly 6 includes a sliding block 61 slidably connected to the inner wall of the transmission square pipe 58. A first through-hole groove 62 is opened on the side wall of the sliding block 61. An air pressure groove 63 is opened on the inner wall of the arc-shaped baffle 36. A first hydraulic pipe 64 is fixedly connected to the inner wall of the air pressure groove 63. A third piston block 65 is slidably connected to the inner wall of the first hydraulic pipe 64. A third spring 66 is fixedly connected to the bottom of the third piston block 65. A second hydraulic telescopic rod 67 is connected through the side wall of the first hydraulic pipe 64. A buffer assembly 7 is fixedly connected to one end of the sliding block 61 close to the first hydraulic pipe 64. As the arc-shaped baffle 36 gradually resets under the push of the arc-shaped spring 37, several arc-shaped baffles 36 approach and are close to each other. At this time, the top of the third piston block 65 will contact the bottom of the rotating pipe 32. At this time, the third piston block 65 compresses the liquid inside the first hydraulic pipe 64 into the second hydraulic telescopic rod 67, causing the second hydraulic telescopic rod 67 to push the sliding block 61 to slide outward along the inner wall of the transmission square pipe 58. At this time, the first through-hole groove 62 coincides with the inner wall of the transmission square pipe 58, enabling the gas inside the first air pressure box 57 to enter the second air pressure box 59 through the gap between the transmission square pipe 58 and the first through-hole groove 62. And the gas inside the second air pressure box 59 is transmitted to the inside of the expansion air bag 52 through the air inlet 510. At this time, multiple arc-shaped baffles 36 are in contact with each other. At this time, the expanded expansion air bag 52 will enter the closing groove 51 between adjacent arc-shaped baffles 36. Through the application of the above components, it is ensured that when each arc-shaped baffle 36 is not operating, the expanded expansion air bag 52 can fill the gap between the arc-shaped baffles 36, avoiding the phenomenon of liquid leakage of the suspension liquid at the top.

[0047] The buffer assembly 7 includes a second hydraulic pipe 71 fixedly connected to one end of the sliding block 61 close to the second hydraulic expansion rod 67. A fourth piston block 72 is slidably connected to the inner wall of the second hydraulic pipe 71. A support rod 73 is fixedly connected to the side wall of the fourth piston block 72. A second through-hole groove 74 is formed in the side wall of the fourth piston block 72. A right-angle groove 75 is formed in the inner wall of the second through-hole groove 74. A rotating plate 76 is rotatably connected to the inner wall of the right-angle groove 75.

[0048] One end of the support rod 73 away from the fourth piston block 72 is fixedly connected to the side wall of the first hydraulic pipe 64. One end of the second hydraulic expansion rod 67 away from the first hydraulic pipe 64 is fixedly connected to the side wall of the sliding block 61. One end of the third spring 66 away from the third piston block 65 is fixedly connected to the bottom of the air pressure groove 63. One end of the arc-shaped pipe 55 away from the second piston block 54 communicates with the side wall of the first air pressure box 57. The outer wall of the L-shaped pipe 42 is fixedly connected to the inner wall of the installation box 311. Utilizing the feature that the second hydraulic expansion rod 67 pushes the sliding block 61 to move outward, a buffer assembly 7 is provided inside the device. As the sliding block 61 moves outward, the distance between the first hydraulic pipe 64 and the sliding block 61 increases, presenting a state as Figure 11 shown. At this time, the support rod 73 will drive the fourth piston block 72 to horizontally move to the left along the inner wall of the second hydraulic pipe 71. At this time, the rotating plate 76 will swing, presenting a state as G in Figure 11 shown. The gap between the rotating plate 76 and the second through-hole groove 74 increases. Therefore, the fourth piston block 72 slides along the second hydraulic pipe 71 at a relatively fast speed. When the device runs again, the arc-shaped baffle 36 swings outward, forcing the second piston block 54 to draw the gas inside the first air pressure box 57 through the spring communication port 56 and the arc-shaped pipe 55. When the pressure on the top of the third piston block 65 is lost, the third spring 66 releases mechanical power, forcing the second hydraulic expansion rod 67 to drive the sliding block 61 to reset. The fourth piston block 72 will move to the right along the inner wall of the second hydraulic pipe 71. At this time, the rotating plate 76 will tilt upward, presenting a state as Figure 12 shown, narrowing the gap between the rotating plate 76 and the second through-hole groove 74, reducing the reset speed of the second hydraulic expansion rod 67. Through the application of the above components, the reset speed of the sliding block 61 is slowed down, avoiding the sliding block 61 from blocking the transmission square pipe 58 too quickly, causing it to be difficult for the second piston block 54 to draw the gas inside the first air pressure box 57, the second air pressure box 59, and the expansion air bag 52, affecting the efficiency of the arc-shaped baffle 36 to open outward.

[0049] A specific application of this embodiment is as follows: Before use, the bracket 1 is installed at the required position. Subsequently, the aircraft part 21 is placed on top of the energized track 12, and the two electromagnetic blocks 23 are moved towards the side wall of the aircraft part 21 while ensuring no contact. Then, the power supply of the electromagnetic blocks 23 is connected through the energized track 12, and the power supply of the motor 39 is also connected. The motor 39 drives the stirring fan blade 312 to rotate through the drive tube 310 and the mounting box 311, stirring the suspension on the inner wall of the storage tank 31 and the top of the arc-shaped baffle 36 to prevent precipitation of the suspension. As the rotation speed of the stirring fan blade 312 and the rotating tube 32 increases, the centrifugal force on the sliding frame 313 and the counterweight 314 increases. At this time, the sliding frame 313 will drive the push rod 315 to contact the inner wall of the arc-shaped baffle 36, forcing the arc-shaped baffle 36 to rotate outward with the shutter 35 as the center. During this process, the arc-shaped baffle 36 is simultaneously squeezed by the liquid inside the storage tank 31, forcing the five arc-shaped baffles 36 to swing outward with the corresponding shutters 35 as the center. As the distance between the arc-shaped baffles 36 increases, the suspension inside the storage tank 31 will fall downward through the gaps between the arc-shaped baffles 36, fall to the bottom of the collection tube 33, and finally be sprayed on the top of the aircraft part 21 through the nozzle 34.

[0050] Taking advantage of the characteristic that the centrifugal force drives the sliding frame 313 and the counterweight 314 to move outward, an adjustment component 4 is provided inside the device. When the counterweight 314 moves outward, the outward-moving counterweight 314 will drive one end of the hydraulic telescopic tube 41 to move outward, and the extended hydraulic telescopic tube 41 will extract the liquid inside the L-shaped tube 42, forcing the piston block 43 to slide downward along the inner wall of the L-shaped tube 42. The five downward-moving piston blocks 43 drive the fixed ring 45 to move downward synchronously through the pulling rod 44. During this process, the fixed ring 45 will control the speed and length of the downward movement of the five piston blocks 43, indirectly controlling the length of the outward extension of the five hydraulic telescopic tubes 41, to prevent the rotation center of the stirring fan blade 312 from shifting due to the influence of sediment, resulting in different positions of the counterweights 314 corresponding to the stirring fan blades 312, which affects the stirring efficiency of the stirring fan blade 312. In addition, while the fixed ring 45 controls the outward movement speed of the multiple hydraulic telescopic tubes 41, when a large piece of sediment adheres to the outer wall of one of the stirring fan blades 312, the corresponding stirring fan blade 312 will be blocked and unable to move, and the blocked counterweight 314 will limit the corresponding hydraulic telescopic tube 41 from extending. At this time, the remaining counterweights 314 cannot move outward either. The centrifugal force borne by the remaining four counterweights 314 will be transmitted to the blocked hydraulic telescopic tube 41 through the corresponding piston block 43, pulling rod 44, and fixed ring 45. The blocked hydraulic telescopic tube 41 will increase the outward thrust to remove the large impurities remaining on the outer wall of the stirring fan blade 312.

[0051] Taking advantage of the characteristic that the above-mentioned arc-shaped baffle 36 rotates outward under the extrusion of the counterweight 314 and the suspension liquid, a sealing component 5 and a limiting component 6 are arranged inside the device. When the spraying of the device is completed, the motor 39 stops running. As the centrifugal force disappears, the first spring 46 drives the fixed ring 45 to reset, forcing the first hydraulic telescopic tube 41 to drive the corresponding counterweight 314 to reset synchronously. As the liquid inside the storage tank 31 decreases, the arc-shaped baffle 36 gradually resets under the push of the arc-shaped spring 37. At this time, the second piston block 54 will slide along the inner wall of the arc-shaped air pressure tube 53, presenting as Figure 8 the state shown in the figure. During the sliding process of the second piston block 54, the gas at the bottom of the second piston block 54 is transmitted to the inside of the first air pressure tank 57 through the communication port 56 and the arc-shaped tube 55. This sliding block 61 will block the transmission square tube 58, restricting the gas from passing through the transmission square tube 58; as the arc-shaped baffle 36 gradually resets under the push of the arc-shaped spring 37, several arc-shaped baffles 36 approach and closely adhere to each other. At this time, the top of the third piston block 65 will contact the bottom of the rotating tube 32. At this time, the third piston block 65 compresses the liquid inside the first hydraulic tube 64 into the second hydraulic telescopic rod 67, causing the second hydraulic telescopic rod 67 to push the sliding block 61 to slide outward along the inner wall of the transmission square tube 58. At this time, the first through-hole groove 62 will coincide with the inner wall of the transmission square tube 58, enabling the gas inside the first air pressure tank 57 to enter the second air pressure tank 59 through the gap between the transmission square tube 58 and the first through-hole groove 62. And the gas inside the second air pressure tank 59 is transmitted to the inside of the expansion airbag 52 through the air inlet 510. At this time, multiple arc-shaped baffles 36 are mutually attached. At this time, the inflated expansion airbag 52 will enter the closing groove 51 between adjacent arc-shaped baffles 36. Through the application of the above components, it is ensured that when each arc-shaped baffle 36 is not operating, the inflated expansion airbag 52 can fill the gap between the arc-shaped baffles 36.

[0052] Taking advantage of the characteristic that the second hydraulic telescopic rod 67 pushes the sliding block 61 to move outward, a buffer component 7 is arranged inside the device. As the sliding block 61 moves outward, the distance between the first hydraulic tube 64 and the sliding block 61 increases, presenting as Figure 11 the state shown in the figure. At this time, the support rod 73 will drive the fourth piston block 72 to horizontally move to the left along the inner wall of the second hydraulic tube 71, and at this time, the rotating plate 76 will swing, presenting Figure 11 the state of G in the figure. The gap between the rotating plate 76 and the second through-hole groove 74 increases. Therefore, the fourth piston block 72 slides along the second hydraulic tube 71 at a relatively fast speed. When the device runs again, the arc-shaped baffle 36 swings outward. When the second piston block 54 extracts the gas inside the first air pressure tank 57 through the spring communication port 56 and the arc-shaped tube 55, the pressure on the top of the third piston block 65 is lost, and the third spring 66 releases mechanical power, forcing the second hydraulic telescopic rod 67 to drive the sliding block 61 to reset. The fourth piston block 72 will move to the right along the inner wall of the second hydraulic tube 71. At this time, the rotating plate 76 will tilt upward, presenting as Figure 12In this state, the gap between the rotating plate 76 and the second through-hole groove 74 is reduced, and the reset speed of the second hydraulic telescopic rod 67 is decreased. Through the application of the above components, the reset speed of the sliding block 61 is slowed down, preventing the sliding block 61 from blocking the transmission square pipe 58 too quickly, which may make it difficult for the second piston block 54 to extract the gas inside the first air pressure box 57, the second air pressure box 59, and the expansion airbag 52, thus affecting the efficiency of the outward opening of the arc-shaped baffle 36.
