Description

TECHNICAL FIELD

[0001] The application relates to the technical field of component detection equipment, in particular to a magnetic particle flaw detector for airplane components. BACKGROUND

[0002] After the flaw detector is prepared, 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 such as cracks, inclusions and pores in the workpiece, the magnetic resistance of the non-ferromagnetic substances is very large, and the magnetic permeability is low; since the magnetic particles in the suspension contain pigments that can emit fluorescence under ultraviolet light, the lines precipitated by the pigments can be observed more clearly under the ultraviolet lamp in the dark, so that the magnetic particle flaw detection process of the workpiece is realized.

[0003] The suspension contains fluorescent pigments and magnetic substances, and the heavy metal substances in the suspension will precipitate; when the equipment detects the airplane components, the components contained in the sprayed suspension are uneven, which causes errors in the flaw detection effect of the equipment; in view of the above problems, the following scheme is proposed. SUMMARY

[0004] To solve the above technical problems, the application provides a magnetic particle flaw detector for airplane components, which comprises a support, a collecting box fixedly connected to the inner wall of the support, and a power supply track fixedly connected to the inner wall of the collecting box.

[0005] The detection mechanism comprises an airplane part, a fixing frame one for clamping and limiting the airplane part, an electromagnetic block, and a blocking rod.

[0006] The side wall of the collecting box is fixedly connected with the side wall of the fixing frame one, the inner wall of the power supply track is slidably connected with the electromagnetic block, the inner wall of the through hole of the electromagnetic block is slidably connected with the outer wall of the blocking rod, and the outer wall of the power supply track is tightly attached to the outer wall of the airplane part.

[0007] Preferably, the spraying assembly comprises a storage tank fixedly connected to one end of the fixing frame one away from the collecting box, a rotating pipe rotatably connected to the bottom of the storage tank, a collecting pipe fixedly connected to the bottom of the fixing frame one, a nozzle penetratingly connected to the bottom of the collecting pipe, and five louver blades fixedly connected to the side wall of the rotating pipe.

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

[0009] Preferably, the spraying assembly further comprises a driving pipe fixedly connected to the output shaft of the motor, six stirring vanes fixedly connected to the outer wall of the mounting box away from the mounting box, an end of the stirring vanes away from the mounting box fixedly connected to the inner wall of the rotating pipe, a sliding frame slidably connected to the outer wall of the stirring vanes, a counterweight fixedly connected to the bottom of the sliding frame, a push rod fixedly connected to the bottom of the counterweight, an adjusting assembly fixedly connected to the inner wall of the mounting box, a blocking assembly fixedly connected to the side wall of the arc-shaped baffle, and a limiting assembly fixedly connected to the inner wall of the arc-shaped baffle. The motor drives the stirring vanes to rotate through the driving pipe and the mounting box, so as to stir the suspension liquid on the inner wall of the storage box and the top of the arc-shaped baffle, avoiding the deposition of the suspension liquid. As the rotating speed of the stirring vanes and the rotating pipe increases, the centrifugal force acting on the sliding frame and the counterweight increases. At this time, the sliding frame drives the push rod to contact the inner wall of the arc-shaped baffle, forcing the arc-shaped baffle to rotate outwardly around the louver blades. In this process, the arc-shaped baffle is synchronously extruded by the liquid in the storage box, forcing the five arc-shaped baffles to swing outwardly around the corresponding louver blades. As the distance between the arc-shaped baffles increases, the suspension liquid in the storage box falls downward through the gap between the arc-shaped baffles and falls into the collecting pipe at the bottom, and is finally sprayed on the top of the aircraft parts through the nozzle. Through the application of the above-mentioned assemblies, the data error caused by the deposition of the suspension liquid during equipment detection is reduced.

[0010] Preferably, the adjusting assembly comprises five hydraulic telescopic pipes one connected through at the side wall of the storage box, one end of the five hydraulic telescopic pipes one away from the mounting box is fixedly connected with the side wall of the counterweight, and the other end of the hydraulic telescopic pipe one away from the counterweight is connected through an L-shaped pipe; the inner wall of one end of the L-shaped pipe away from the hydraulic telescopic pipe one is slidably connected with a piston block one; the top of the piston block one is fixedly connected with a pull rod; one end of the five pull rods away from the piston block one is fixedly connected with a fixed ring; the top of the fixed ring is fixedly connected with a spring one; one end of the spring one away from the fixed ring is fixedly connected with a fixed disc; and the side wall of the fixed disc is fixedly connected with the inner wall of the driving pipe. By using the characteristics that the sliding frame and the counterweight are driven to move outward by the centrifugal force, the adjusting assembly is arranged in the equipment. When the counterweight moves outward, the outward moving counterweight drives one end of the hydraulic telescopic pipe one to move outward, and the extended hydraulic telescopic pipe one extracts the liquid in the L-shaped pipe, forcing the piston block one to slide downward along the inner wall of the L-shaped pipe. The five downward moving piston blocks one drive the fixed ring to move downward synchronously through the pull rod. In this process, the fixed ring controls the speed and length of the downward movement of the five piston blocks one, indirectly controls the length of the outward extension of the five hydraulic telescopic pipes one, avoids the influence of the sediment, causes each counterweight to be in different positions of the corresponding stirring fan blade, causes the rotation center of gravity of the stirring fan blade to deviate, and affects the stirring efficiency of the stirring fan blade.

[0011] Preferably, the plugging assembly comprises a closed groove opened at both ends of the arc-shaped baffle, the inner wall of the closed groove on the left side of the arc-shaped baffle is fixedly connected with an inflatable air bag, the side wall of the rotating pipe is fixedly connected with an arc-shaped air pressure pipe, the inner wall of the arc-shaped air pressure pipe is slidably connected with a piston block two, the side wall of the piston block two is fixedly connected with an arc-shaped pipe, and the side wall of the arc-shaped pipe is provided with a flow port. By controlling the outward movement speed of the plurality of hydraulic telescopic pipes one through the fixed ring, when one of the stirring fan blades has a large amount of sediment adhered to the outer wall, the corresponding stirring fan blade will be blocked and unable to move, and the blocked counterweight will limit the extension of the corresponding hydraulic telescopic pipe one. At this time, the remaining counterweights cannot move outward, and the centrifugal force borne by the remaining four counterweights is transmitted to the blocked hydraulic telescopic pipe one through the corresponding piston block one, pull rod and fixed ring. The blocked hydraulic telescopic pipe one increases the outward pushing force to remove the large amount of impurities remaining on the outer wall of the stirring fan blade.

[0012] Preferably, the sealing assembly further includes a pressure box one fixedly connected to the side wall of the arc-shaped baffle. A transmission square tube is connected through the side wall of pressure box one. A pressure box two is fixedly connected to the end of the transmission square tube away from pressure box one. An air inlet is opened on the side wall of pressure box two. The end of the air inlet away from pressure box two is connected through to the inner wall of the expansion air bladder. Utilizing the characteristic that the arc-shaped baffle rotates outward under the pressure of the counterweight and the suspension, a sealing assembly and a limiting assembly are set inside the equipment. After the equipment finishes spraying, the motor stops running. As the centrifugal force disappears, spring one drives the fixed ring to reset, forcing hydraulic telescopic tube one 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, piston block two will slide along the inner wall of the arc-shaped air pressure tube, presenting as... Figure 8 In the state where piston block two slides, the gas at the bottom of piston block two is transmitted to the inside of pressure box one through the flow port and the arc-shaped pipe. This sliding block will block the transmission tube, restricting the gas from passing through the transmission tube.

[0013] Preferably, the limiting component includes a sliding block slidably connected to the inner wall of the transmission square tube. A through-hole groove is formed on the side wall of the sliding block. A pneumatic groove is formed on the inner wall of the arc-shaped baffle. A hydraulic pipe is fixedly connected to the inner wall of the pneumatic groove. A piston block is slidably connected to the inner wall of the hydraulic pipe. A spring is fixedly connected to the bottom of the piston block. A hydraulic telescopic rod is connected through the side wall of the hydraulic pipe. A buffer component is fixedly connected to the end of the sliding block near the hydraulic pipe. As the arc-shaped baffle gradually resets under the push of the arc-shaped spring, several arc-shaped baffles approach and press against each other. At this time, the top of the piston block will contact the bottom of the rotating tube, and the piston block will compress... Liquid inside hydraulic pipe one enters hydraulic telescopic rod two, causing hydraulic telescopic rod two to push the sliding block outward along the inner wall of the transmission square tube. At this time, through-hole groove one will coincide with the inner wall of the transmission square tube, allowing gas inside pressure box one to enter pressure box two through the gap between the transmission square tube and through-hole groove one. Gas inside pressure box two is then transmitted to the inflatable air bladder through the air inlet. At this time, multiple arc-shaped baffles are in contact with each other, and the inflated air bladder will enter the closed groove of the adjacent arc-shaped baffles. Through the application of the above components, it is ensured that when each arc-shaped baffle is not in operation, the inflated air bladder can fill the gap between the arc-shaped baffles, preventing leakage of the suspension at the top.

[0014] Preferably, the buffer assembly includes a hydraulic pipe 2 fixedly connected to one end of the sliding block near the hydraulic telescopic rod 2, a piston block 4 slidably connected to the inner wall of the hydraulic pipe 2, a support rod fixedly connected to the side wall of the piston block 4, a through hole groove 2 opened on the side wall of the piston block 4, a right angle groove opened on the inner wall of the through hole groove 2, and a rotating plate rotatably connected to the inner wall of the right angle groove.

[0015] Preferably, the end of the support rod away from the piston block four is fixedly connected to the side wall of the hydraulic pipe one; the end of the hydraulic telescopic rod two away from the hydraulic pipe one is fixedly connected to the side wall of the sliding block; the end of the spring three away from the piston block three is fixedly connected to the bottom of the air pressure groove; the end of the arc-shaped tube away from the piston block two is connected through to the side wall of the air pressure box one; and the outer wall of the L-shaped tube is fixedly connected to the inner wall of the mounting box. Utilizing the characteristic of the hydraulic telescopic rod two pushing the sliding block outward, a buffer assembly is provided inside the equipment. As the sliding block moves outward, the distance between the hydraulic pipe one and the sliding block increases, presenting a... Figure 11 In this state, the support rod will drive the piston block four to move laterally to the left along the inner wall of the hydraulic pipe two, and at this time the rotating plate will swing, presenting... Figure 11 In the state of G, the gap between the rotating plate and the through-hole groove two widens, so the piston block four slides along the hydraulic pipe two at a faster speed. When the equipment runs again, the arc-shaped baffle swings outward, forcing the piston block two spring flow port and the arc-shaped pipe to draw gas from the air pressure box one. At this time, the top of the piston block three loses pressure, the spring three releases mechanical power, forcing the hydraulic telescopic rod two to drive the sliding block to reset. The piston block four will move to the right along the inner wall of the hydraulic pipe two, and at this time the rotating plate will tilt upward, presenting as... Figure 12 The state of the rotating plate and the through-hole groove 2 is reduced, and the reset speed of the hydraulic telescopic rod 2 is reduced. Through the application of the above components, the reset speed of the sliding block is slowed down, so as to avoid the sliding block blocking the transmission square tube too quickly, which would make it difficult for the piston block 2 to extract the gas inside the pressure box 1, pressure box 2 and expansion air bag, and affect the efficiency of the arc baffle opening outward.

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

[0017] (1) This invention addresses the problem of suspension sedimentation by incorporating a spraying assembly inside the device. Before use, the bracket is installed in the desired position, then the aircraft parts are placed on top of the energized track, and the two electromagnetic blocks are moved toward the side wall of the aircraft parts, ensuring they do not contact each other. The power supply to the electromagnetic blocks is then connected via the energized track, and the power supply to the motor is also connected. The motor, through the drive tube and mounting box, drives the stirring blades to rotate, stirring the suspension on the inner wall of the storage tank and the top of the arc-shaped baffle to prevent sedimentation. As the rotation speed of the stirring blades and rotating tube increases, the sliding frame and counterweight are subjected to… As the centrifugal force increases, 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 around the louvers. During this process, the arc-shaped baffle is simultaneously squeezed by the liquid inside the storage tank, causing the five arc-shaped baffles to swing outward around their corresponding louvers. 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 into the bottom of the collection pipe, eventually being sprayed onto the top of the aircraft parts through the nozzle. By using the above components, the data error caused by the sedimentation of the suspension during equipment testing is reduced.

[0018] (2) This invention utilizes the characteristic of centrifugal force driving the sliding frame and counterweight to move outward. An adjustment component is installed inside the equipment. When the counterweight moves outward, the outward-moving counterweight drives one end of the hydraulic telescopic tube to move outward. The extended hydraulic telescopic tube will draw liquid from inside the L-shaped tube, forcing the piston block to slide downward along the inner wall of the L-shaped tube. The five downward-moving piston blocks drive the fixing ring to move downward synchronously through the pulling rod. During this process, the fixing ring will control the downward speed and length of the five piston blocks, indirectly controlling the outward extension length of the five hydraulic telescopic tubes, avoiding the influence of sediment causing each counterweight to be in the corresponding stirring fan position. The different positions of the blades cause the rotation center of gravity of the agitator blades to shift, affecting the agitator blades' agitation efficiency. In addition, while the speed of the outward movement of multiple hydraulic telescopic tubes is controlled by the fixed ring, when a large piece of sediment adheres to the outer wall of one of the agitator blades, the corresponding agitator blade will be obstructed and unable to move. The obstructed counterweight will restrict the extension of the corresponding hydraulic telescopic tube, and the remaining counterweight will also be unable to move outward. The centrifugal force borne by the remaining four counterweights will be transmitted to the obstructed hydraulic telescopic tube through the corresponding piston block, the pulling rod, and the fixed ring. The obstructed hydraulic telescopic tube will increase its outward thrust to remove the large pieces of impurities remaining on the outer wall of the agitator blade.

[0019] (3) This invention utilizes the characteristic of the arc-shaped baffle rotating outward under the pressure of the counterweight and the suspension. A sealing component and a limiting component are installed inside the equipment. After spraying is completed, the motor stops running. As the centrifugal force disappears, spring one drives the fixed ring to reset, forcing hydraulic telescopic pipe one to synchronously reset the corresponding counterweight. 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, piston block two will slide along the inner wall of the arc-shaped air pressure pipe, presenting as... Figure 8 In the sliding state, during the sliding process of piston block two, the gas at the bottom of piston block two is transmitted to the interior of pressure box one through the flow port and arc-shaped pipe. This sliding block will block the transmission pipe, restricting the gas from passing through the transmission pipe. As the arc-shaped baffle gradually resets under the push of the arc-shaped spring, several arc-shaped baffles approach each other and stick together. At this time, the top of piston block three will contact the bottom of the rotating pipe. At this time, piston block three compresses the liquid inside hydraulic pipe one into hydraulic telescopic rod two, causing hydraulic telescopic rod two to push the sliding block to slide outward along the inner wall of the transmission pipe. At this point, the through-hole groove one will coincide with the inner wall of the transmission square tube, allowing the gas inside the first pressure box to enter the second pressure box through the gap between the transmission square tube and the through-hole groove one. The gas inside the second pressure box is then transmitted to the inside of the expansion airbag through the air inlet. At this time, multiple arc-shaped baffles are in contact with each other, and the expanded airbag will enter the closed groove of the adjacent arc-shaped baffles. Through the application of the above components, it is ensured that when each arc-shaped baffle is not in operation, the expanded airbag can fill the gap between the arc-shaped baffles, preventing leakage of the suspension at the top.

[0020] (4) This invention utilizes the characteristic of the hydraulic telescopic rod II to push the sliding block outward. A buffer assembly is installed inside the device. As the sliding block moves outward, the distance between the hydraulic pipe I and the sliding block increases, resulting in the following... Figure 11 In this state, the support rod will drive the piston block four to move laterally to the left along the inner wall of the hydraulic pipe two, and at this time the rotating plate will swing, presenting... Figure 11 In the state of G, the gap between the rotating plate and the through-hole groove two widens, so the piston block four slides along the hydraulic pipe two at a faster speed. When the equipment runs again, the arc-shaped baffle swings outward, forcing the piston block two spring flow port and the arc-shaped pipe to draw gas from the air pressure box one. At this time, the top of the piston block three loses pressure, the spring three releases mechanical power, forcing the hydraulic telescopic rod two to drive the sliding block to reset. The piston block four will move to the right along the inner wall of the hydraulic pipe two, and at this time the rotating plate will tilt upward, presenting as... Figure 12 The state of the rotating plate and the through-hole groove 2 is reduced, and the reset speed of the hydraulic telescopic rod 2 is reduced. Through the application of the above components, the reset speed of the sliding block is slowed down, so as to avoid the sliding block blocking the transmission square tube too quickly, which would make it difficult for the piston block 2 to extract the gas inside the pressure box 1, pressure box 2 and expansion air bag, and affect the efficiency of the arc baffle opening outward.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figure 1 - Figure 6 The present invention is a magnetic particle flaw detector for aircraft parts, including a support 1, a collection box 11 fixedly connected to the inner wall of the support 1, and an electric track 12 fixedly connected to the inner wall of the collection box 11.

[0038] Testing mechanism 2 includes aircraft parts, a fixing frame 22 for clamping and restricting aircraft parts 21, an electromagnetic block 23, a blocking bar 24, and a spraying assembly 3 for spraying magnetic levitation solution.

[0039] The side wall of the collection box 11 is fixedly connected to the side wall of the fixed frame 22. The inner wall of the energized track 12 is slidably connected to the electromagnetic block 23. The inner wall of the collection box 11 is fixedly connected to the outer wall of the blocking rod 24. The inner wall of the through hole of the electromagnetic block 23 is slidably connected to the outer wall of the blocking rod 24. 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 box 31 fixedly connected to the end of the mounting bracket 22 away from the collection box 11. A rotating tube 32 is rotatably connected to the bottom of the storage box 31. A collection tube 33 is fixedly connected to the bottom of the mounting bracket 22. A nozzle 34 is connected through the bottom of the collection tube 33. Five louvers 35 are fixedly connected to the side wall of the rotating tube 32. Before use, the bracket 1 is installed in the required position. Then, the aircraft part 21 is placed on the top of the energized rail 12, and the two electromagnetic blocks 23 are moved toward the side wall of the aircraft part 21, ensuring that they do not contact each other. Then, the power supply of the electromagnetic blocks 23 is turned on through the energized rail 12.

[0041] The spraying assembly 3 also includes an arc-shaped baffle 36 fixedly connected to the 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. The 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 box 31. A motor 39 is fixedly connected to the top of the second fixing frame 38.

[0042] The spraying assembly 3 also includes a drive pipe 310 fixedly connected to the output shaft of the motor 39. A mounting box 311 is fixedly connected to the end of the drive pipe 310 away from the motor 39. Six stirring blades 312 are fixedly connected to the outer wall of the mounting box 311. The ends of the stirring blades 312 away from the mounting box 311 are 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 blades 312. A counterweight 314 is fixedly connected to the bottom of the sliding frame 313. A push rod 315 is fixedly connected to the bottom of the counterweight 314. An adjusting assembly 4 is fixedly connected to the inner wall of the mounting box 311. A sealing 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 blades 312 to rotate via the drive pipe 310 and the mounting box 311, thus rotating the inner wall of the storage tank 31 and the top of the arc-shaped baffle 36. The suspension is stirred to prevent sedimentation. As the speed of the stirring fan blades 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 around the louver 35. 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 around the corresponding louver 35. As the distance between the arc-shaped baffles 36 increases, the suspension inside the storage tank 31 will fall down through the gaps between the arc-shaped baffles 36 and into the bottom of the collection tube 33. Finally, it will be sprayed onto the top of the aircraft part 21 through the nozzle 34. By using the above components, the data error caused by suspension sedimentation during equipment testing is reduced.

[0043] Example 2, please refer toFigure 7 - Figure 12 This invention relates to a magnetic particle flaw detector for aircraft parts. Based on Embodiment 1, the adjusting assembly 4 includes five hydraulic telescopic tubes 41 that are connected through to the side wall of the storage box 31. The ends of the five hydraulic telescopic tubes 41 away from the mounting box 311 are fixedly connected to the side wall of the counterweight block 314. An L-shaped tube 42 is connected through to the ends of the hydraulic telescopic tubes 41 away from the counterweight block 314. A piston block 43 is slidably connected to the inner wall of the end of the L-shaped tube 42 away from the hydraulic telescopic tubes 41. A pulling rod 44 is fixedly connected to the top of the piston block 43. A fixing ring 45 is fixedly connected to the ends of the five pulling rods 44 away from the piston block 43. A spring 46 is fixedly connected to the top of the fixing ring 45. A fixing disk 47 is fixedly connected to the end of the spring 46 away from the fixing ring 45. The side wall of the fixing disk 47 is fixedly connected to the inner wall of the drive tube 310. The centrifugal force is used to... The sliding frame 313 and counterweight 314 move outwards. An adjustment component 4 is installed inside the equipment. When the counterweight 314 moves outwards, the outward-moving counterweight 314 drives one end of the hydraulic telescopic tube 41 to move outwards. The extended hydraulic telescopic tube 41 draws liquid from inside the L-shaped tube 42, forcing the piston block 43 to slide downwards along the inner wall of the L-shaped tube 42. The five downward-moving piston blocks 43 drive the fixing ring 45 to move downwards synchronously through the pulling rod 44. During this process, the fixing ring 45 controls the downward speed and length of the five piston blocks 43, indirectly controlling the outward extension length of the five hydraulic telescopic tubes 41. This avoids the influence of sediment causing each counterweight 314 to be in a different position on the corresponding stirring blade 312, resulting in a shift in the rotation center of gravity of the stirring blade 312 and affecting the stirring efficiency of the stirring blade 312.

[0044] The sealing assembly 5 includes closed grooves 51 formed at both ends of the arc-shaped baffle 36. An expansion airbag 52 is fixedly connected to the inner wall of the closed groove 51 on the left side of the arc-shaped baffle 36. An arc-shaped air pressure pipe 53 is fixedly connected to the side wall of the rotating pipe 32. A piston block 54 is slidably connected to the inner wall of the arc-shaped air pressure pipe 53. An arc-shaped pipe 55 is fixedly connected to the side wall of the piston block 54. A flow port 56 is formed on the side wall of the arc-shaped pipe 55. While controlling the outward movement speed of multiple hydraulic telescopic pipes 41 through the fixing ring 45, when one of the stirring fan blades 31... 2. When large pieces of sediment adhere to the outer wall, the corresponding stirring blade 312 will be obstructed and unable to move. The obstructed counterweight 314 will restrict the extension of the corresponding hydraulic telescopic tube 41. At this time, the remaining counterweight 314 will also be unable to move outward. The centrifugal force borne by the remaining four counterweights 314 will be transmitted to the obstructed hydraulic telescopic tube 41 through the corresponding piston block 43, the pulling rod 44 and the fixing ring 45. The obstructed hydraulic telescopic tube 41 will increase the outward thrust and remove the large impurities remaining on the outer wall of the stirring blade 312.

[0045] The sealing assembly 5 also includes a pressure box 57 fixedly connected to the side wall of the arc-shaped baffle 36. A transmission square tube 58 is connected through the side wall of the pressure box 57. A second pressure box 59 is fixedly connected to the end of the transmission square tube 58 away from the pressure box 57. An air inlet 510 is provided on the side wall of the second pressure box 59. The end of the air inlet 510 away from the second pressure box 59 is connected through the inner wall of the inflatable airbag 52. The arc-shaped baffle 36 is compressed by the counterweight 314 and the suspension. The device features outward rotation and includes a sealing component 5 and a limiting component 6 inside. After spraying, the motor 39 stops. As centrifugal force disappears, spring 46 drives the fixed ring 45 to reset, forcing the hydraulic telescopic tube 41 to synchronously reset the corresponding counterweight 314. 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, piston block 54 slides along the inner wall of the arc-shaped air pressure tube 53, presenting a... Figure 8 In the state where piston block 2 54 slides, the gas at the bottom of piston block 2 54 is transmitted to the inside of pressure box 1 57 through the flow port 56 and the arc-shaped pipe 55. This sliding block 61 will block the transmission pipe 58, restricting the gas from passing through the transmission pipe 58.

[0046] The limiting component 6 includes a sliding block 61 slidably connected to the inner wall of the transmission square tube 58. A through-hole groove 62 is formed on the side wall of the sliding block 61. A pneumatic groove 63 is formed on the inner wall of the arc-shaped baffle 36. A hydraulic pipe 64 is fixedly connected to the inner wall of the pneumatic groove 63. A piston block 65 is slidably connected to the inner wall of the hydraulic pipe 64. A spring 66 is fixedly connected to the bottom of the piston block 65. A hydraulic telescopic rod 67 is connected through the side wall of the hydraulic pipe 64. A buffer component 7 is fixedly connected to the end of the sliding block 61 near the 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 press against each other. At this time, the top of the piston block 65 will contact the bottom of the rotating tube 32, and the piston block 65 will compress... Liquid inside hydraulic pipe 64 enters hydraulic telescopic rod 67, causing it to push sliding block 61 outward along the inner wall of transmission square tube 58. At this time, through-hole groove 62 overlaps with the inner wall of transmission square tube 58, allowing gas inside pressure box 57 to enter pressure box 59 through the gap between transmission square tube 58 and through-hole groove 62. Gas inside pressure box 59 is then transmitted to the inflatable airbag 52 through air inlet 510. At this time, multiple arc-shaped baffles 36 are in contact with each other, and the inflated airbag 52 enters the closed groove 51 of adjacent arc-shaped baffles 36. Through the application of the above components, the inflated airbag 52 can fill the gaps between the arc-shaped baffles 36 when they are not in operation, preventing leakage of the suspension at the top.

[0047] The buffer assembly 7 includes a hydraulic pipe 71 fixedly connected to one end of the sliding block 61 near the hydraulic telescopic rod 67. A piston block 72 is slidably connected to the inner wall of the hydraulic pipe 71. A support rod 73 is fixedly connected to the side wall of the piston block 72. A through-hole groove 74 is opened on the side wall of the piston block 72. A right-angle groove 75 is opened on the inner wall of the 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 piston block 72, is fixedly connected to the side wall of the hydraulic pipe 64. One end of the hydraulic telescopic rod 67, away from the hydraulic pipe 64, is fixedly connected to the side wall of the sliding block 61. One end of the spring 66, away from the piston block 65, is fixedly connected to the bottom of the pneumatic groove 63. One end of the arc-shaped pipe 55, away from the piston block 54, is connected through to the side wall of the pneumatic box 57. The outer wall of the L-shaped pipe 42 is fixedly connected to the inner wall of the mounting box 311. Utilizing the characteristic of the hydraulic telescopic rod 67 pushing the sliding block 61 outward, a buffer assembly 7 is installed inside the equipment. As the sliding block 61 moves outward, the distance between the hydraulic pipe 64 and the sliding block 61 increases, presenting a... Figure 11 In this state, the support rod 73 will drive the piston block 72 to move laterally to the left along the inner wall of the hydraulic pipe 71, and at this time the rotating plate 76 will swing, presenting... Figure 11 In the state of G, the gap between the rotating plate 76 and the through-hole groove 74 widens, so the piston block 72 slides along the hydraulic pipe 71 at a faster speed. When the equipment runs again, the arc-shaped baffle 36 swings outward, forcing the piston block 54, spring flow port 56, and arc-shaped pipe 55 to draw gas from the air pressure box 57. At this time, the top of the piston block 65 loses pressure, the spring 66 releases mechanical power, forcing the hydraulic telescopic rod 67 to drive the sliding block 61 to reset. The piston block 72 will move to the right along the inner wall of the hydraulic pipe 71, and at this time the rotating plate 76 will tilt upward, presenting a position like... Figure 12 The state of the rotating plate 76 and the through hole groove 74 is reduced, and the reset speed of the hydraulic telescopic rod 67 is reduced. Through the application of the above components, the reset speed of the sliding block 61 is slowed down, so as to avoid the sliding block 61 blocking the transmission square tube 58 too quickly, making it difficult for the piston block 54 to extract the gas inside the pressure box 57, pressure box 59 and expansion air bag 52, thus affecting the efficiency of the arc baffle 36 opening outward.

[0049] A specific application of this embodiment is as follows: Before use, the bracket 1 is installed in the required position. Then, the aircraft part 21 is placed on top of the energized rail 12, and the two electromagnetic blocks 23 are moved toward the side wall of the aircraft part 21, ensuring they do not contact each other. Then, the power supply to the electromagnetic blocks 23 is connected through the energized rail 12, and the power supply to the motor 39 is also connected. The motor 39 drives the stirring 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 sedimentation. As the rotation speed of the stirring blade 312 and the rotating tube 32 increases, the sliding frame... The centrifugal force on 313 and 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 around the louver 35. 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 around the corresponding louver 35. As the distance between each arc-shaped baffle 36 increases, the suspension inside the storage tank 31 will fall down through the gap between the arc-shaped baffles 36 and fall into the bottom of the collection pipe 33, and finally be sprayed onto the top of the aircraft part 21 through the nozzle 34.

[0050] Utilizing the centrifugal force that drives the sliding frame 313 and counterweight 314 to move outward, an adjustment component 4 is installed inside the equipment. When the counterweight 314 moves outward, it drives one end of the hydraulic telescopic tube 41 to move outward as well. The extended hydraulic telescopic tube 41 draws liquid from 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 fixing ring 45 to move downward synchronously via the pulling rod 44. During this process, the fixing ring 45 controls the downward speed and length of the five piston blocks 43, indirectly controlling the outward extension length of the five hydraulic telescopic tubes 41. This prevents the counterweight 314 from being misaligned with the corresponding stirring blade 312 due to the influence of sediment. At the same position, the rotation center of gravity of the stirring blade 312 shifts, affecting the stirring efficiency of the stirring blade 312. In addition, while controlling the outward movement speed of multiple 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 blades 312, the corresponding stirring blade 312 will be blocked and unable to move. The blocked counterweight 314 will restrict the extension of the corresponding hydraulic telescopic tube 41. At this time, the remaining counterweight 314 will also be unable to move outward. 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, the pulling rod 44 and the fixing ring 45. The blocked hydraulic telescopic tube 41 will increase the outward thrust to remove the large pieces of impurities remaining on the outer wall of the stirring blade 312.

[0051] Utilizing the characteristic of the arc-shaped baffle 36 rotating outward under the pressure of the counterweight 314 and the suspension, a sealing component 5 and a limiting component 6 are installed inside the equipment. After the equipment finishes spraying, the motor 39 stops running. As the centrifugal force disappears, the spring 46 drives the fixed ring 45 to reset, forcing the hydraulic telescopic pipe 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 piston block 54 will slide along the inner wall of the arc-shaped air pressure pipe 53, presenting a state as follows. Figure 8 In the state where piston block 2 54 slides, the gas at the bottom of piston block 2 54 is transmitted to the inside of pressure box 1 57 through the flow port 56 and the arc-shaped pipe 55. This sliding block 61 will block the transmission pipe 58, restricting the gas from passing through the transmission pipe 58. As the arc-shaped baffle 36 is gradually reset under the push of the arc-shaped spring 37, several arc-shaped baffles 36 approach each other and stick together. At this time, the top of piston block 3 65 will contact the bottom of the rotating pipe 32. At this time, piston block 3 65 compresses the liquid inside the hydraulic pipe 1 64 into the hydraulic telescopic rod 2 67, so that the hydraulic telescopic rod 2 67 pushes the sliding block 61 along the transmission pipe 57. The inner wall of the square tube 58 slides outward, at which time the through-hole groove 62 and the inner wall of the transmission square tube 58 will overlap, allowing the gas inside the first pressure box 57 to enter the second pressure box 59 through the gap between the transmission square tube 58 and the through-hole groove 62. The gas inside the second pressure box 59 is then transmitted to the inside of the inflatable airbag 52 through the air inlet 510. At this time, multiple arc-shaped baffles 36 are in contact with each other, and the inflated airbag 52 will enter the closed groove 51 of the adjacent arc-shaped baffles 36. Through the application of the above components, it is ensured that when each arc-shaped baffle 36 is not in operation, the inflated airbag 52 can fill the gap between the arc-shaped baffles 36.

[0052] Utilizing the characteristic of the hydraulic telescopic rod 67 pushing the sliding block 61 outward, a buffer assembly 7 is installed inside the equipment. As the sliding block 61 moves outward, the distance between the hydraulic pipe 64 and the sliding block 61 increases, resulting in the following... Figure 11 In this state, the support rod 73 will drive the piston block 72 to move laterally to the left along the inner wall of the hydraulic pipe 71, and at this time the rotating plate 76 will swing, presenting... Figure 11 In the state of G, the gap between the rotating plate 76 and the through-hole groove 74 widens, so the piston block 72 slides along the hydraulic pipe 71 at a faster speed. When the equipment runs again, the arc-shaped baffle 36 swings outward, forcing the piston block 54, spring flow port 56, and arc-shaped pipe 55 to draw gas from the air pressure box 57. At this time, the top of the piston block 65 loses pressure, the spring 66 releases mechanical power, forcing the hydraulic telescopic rod 67 to drive the sliding block 61 to reset. The piston block 72 will move to the right along the inner wall of the hydraulic pipe 71, and at this time the rotating plate 76 will tilt upward, presenting a position like... Figure 12The state of the rotating plate 76 and the through hole groove 74 is reduced, and the reset speed of the hydraulic telescopic rod 67 is reduced. Through the application of the above components, the reset speed of the sliding block 61 is slowed down, so as to avoid the sliding block 61 blocking the transmission square tube 58 too quickly, making it difficult for the piston block 54 to extract the gas inside the pressure box 57, pressure box 59 and expansion air bag 52, thus affecting the efficiency of the arc baffle 36 opening outward.
