[0003] The wiring of an aircraft engine primarily serves the purpose of controlling and transmitting signals. In aircraft engines, wiring connects various sensors and actuators, responsible for monitoring various engine parameters and controlling the engine's operating status. Specifically, these wiring functions include: Monitoring engine status: The wiring collects various engine parameters such as temperature, pressure, and speed through sensors. This data helps pilots and ground maintenance personnel understand the engine's operating status; Controlling engine operation: By transmitting signals through the wiring, the control system can adjust the engine's fuel supply, air intake, and other parameters to ensure that the engine operates in optimal condition; Fault diagnosis: The wiring can also transmit fault signals to help quickly locate and eliminate engine faults.

[0004] When the engine circuit is put into actual operation, its physical properties need to be tested, including tensile strength and anti-twist fracture ability. During the testing, the above two performance tests need to be performed on two different devices. The functionality of the equipment is relatively single, and the frequent replacement of equipment is inefficient and inconvenient for manual operation, which reduces the practicality and work efficiency of the device.

[0009] A sleeve is fixedly mounted on each of the second rotating gear and the second rotating wheel. A positioning groove connected to the circuit is provided at one end of the sleeve, and a positioning hole is provided on the sleeve and is connected to the circuit by locking and fixing with an adjusting bolt.

[0010] The tensile detection mechanism includes a second motor fixed on the base plate, the output shaft of the second motor is connected to a screw shaft distributed along the length direction of the base plate, a slider is spirally transmitted on the screw shaft, and the top of the slider is connected to an arc-shaped pull hook placed on the line through a cylinder.

[0011] Furthermore, a limiting groove is provided on the bottom plate at the edge of the outer wall of the screw shaft, the piston rod on the cylinder and the arc-shaped pull hook are connected by a lifting rod, the outside of the lifting rod is placed in the water tank, and the bottom end of the water tank is connected to the bottom plate by a fixing frame on all four sides, the lifting rod and the push plates at both ends of the bottom of the inner wall of the water tank are connected by a first swing rod, and the push plate and the baffle on the first storage box are connected by a second swing rod.

[0012] Furthermore, the top of the pushing plate is triangular in shape, the baffle plate is movably limited and connected to the slide groove of the outer wall of the first storage box, and the outer wall of the baffle plate is provided with filter holes adapted thereto, and both ends of the outer wall of the first storage box are integrally formed with L-shaped bent plates connected to the top support of the water tank, and a handle placed on the first storage box is provided between the L-shaped bent plates.

[0013] Furthermore, an inclined surface is connected to the opening of the outer wall of the first storage box near the baffle plate, both ends of the first swing arm are installed on the lifting rod and the push plate by a rotating connection, and both ends of the second swing arm are installed on the push plate and the baffle plate by a rotating connection. A second storage box symmetrical with the center of the lifting rod is provided on both sides of the bottom end of the water tank, and the second storage box is a movable pull-out design.

[0014] Furthermore, it also includes a water purification mechanism, which includes a bracket fixed at both ends of the lifting rod, and the extended end of the top of the bracket passes through the shell and extends to the first gear plate inside the shell. The outer wall of the first gear plate is engaged with the second gear plate that moves in the opposite direction through the center gear meshing transmission, and the top ends of the first gear plate and the second gear plate are correspondingly connected to the first baffle and the second baffle.

[0015] Furthermore, the shell and the water tank are connected by locking and fixing with positioning pins, and the first baffle and the second baffle are connected with movable openings near the material guide pipe. The material guide pipe is distributed at an angle, and the outer wall edge of the center rotating tooth is provided with a rotating groove placed on the inner wall of the shell.

[0017] Furthermore, a guide trough connected to the activated carbon particles is provided in the guide tube. As the first baffle moves upward and contacts the top of the inner wall of the guide tube, the second baffle moves downward and closes the movable opening on the guide tube.

[0018] The fixed frame and the slider around the bottom of the water tank are connected by a synchronization rod. As the slider moves, the synchronization rod drives the water tank to move horizontally synchronously.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] (1) In the present invention, during the torsion test, the two ends of the cable are first inserted into the positioning grooves of the sleeve respectively, and then straightened and fixed by adjusting the bolt. The first motor starts and drives the first rotating tooth and the first rotating wheel to rotate. Under the meshing transmission of the gears and the transmission of the conveyor belt, the sleeves at both ends drive the cable to rotate in the opposite direction, thereby achieving effective torsion test work. At the same time, the rotation speed between the second rotating tooth and the second rotating wheel remains the same, so that the two ends of the cable are subjected to the same force. This can ensure the stability of the torsion work and prevent one end of the cable from being subjected to excessive torque and affecting the accuracy of the test.

[0021] (2) In the present invention, when the tensile test is in progress, the second motor cooperates with the arc-shaped hook on the cylinder to perform tensile strength test on cables at different positions. In addition, when the arc-shaped hook moves downward, it can drive the corresponding position of the cable to move into the water tank, so that the cable sealing test can be carried out at the same time. In order to reuse the water body, a large amount of impurities will be attached to the water body during high-frequency sealing test. During the up and down movement of the lifting rod, the pushing plates at both ends can be driven to move back and forth horizontally. During the movement of the pushing plates, the activated carbon after adsorbing impurities can be pushed into the first storage box and the second storage box. The first storage box is a handle-type movable design, and the second storage box is a pull-out movable design. Moreover, the shielding plate on the first storage box can effectively close the opening when the impurities are pushed into the box body under the rotation connection of the second swing rod, and open the opening during the pushing process. This can facilitate the operation of personnel on the one hand, and avoid the situation of motion interference between structural parts on the other hand, thereby ensuring the stability and safety of the device.

[0022] (3) In the present invention, the tensile strength and torsional strength of the cable can be tested separately, and the torsional strength can be tested simultaneously with the tensile strength of the wire and cable without changing the equipment, thereby improving the testing efficiency.

[0023] (4) In the present invention, activated carbon particles for adsorbing impurities are placed in the material box. During the movement of the lifting rod, the first gear plate on the bracket can be driven to move synchronously. Under the gear meshing transmission, the first baffle and the second baffle can move up and down in an interlaced manner, thereby effectively blocking the continuously descending activated carbon particles. Moreover, during the blocking process, the quantitative cavity formed between the first baffle and the second baffle can automatically quantify the activated carbon, preventing the particles from continuously falling into the water tank, avoiding the situation of excessive use of activated carbon particles, effectively utilizing resources, and having a strong automation effect.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Reference Manual Figure 1 -Attached Figure 9 As shown, an automatic detection device for aircraft engine circuits includes: an anti-torsion detection mechanism 1, the anti-torsion detection mechanism 1 includes side plates 2 fixed to both ends of a base plate, a first motor 3 fixedly mounted on one end of the side plates 2, an output shaft of the first motor 3 passing through the side plates 2 and extending through a first rotating tooth 4 to a first rotating wheel 5, the outer wall of the first rotating tooth 4 meshingly engaging with a second rotating tooth 6 rotating in the opposite direction, and the first rotating wheel 5 is connected to a second rotating wheel 8 rotating in the same direction via a conveyor belt 7;

[0037] During the torsion resistance test, first insert the two ends of the cable into the positioning grooves of the sleeve 9 respectively, and then straighten and fix it by rotating the adjusting bolt 10. The first motor 3 starts and drives the first rotating tooth 4 and the first rotating wheel 5 to rotate. Under the meshing transmission of the gears and the transmission action of the conveyor belt 7, the sleeves 9 at both ends drive the cables to rotate in the opposite direction, thereby realizing effective torsion resistance detection. At the same time, the rotation speed between the second rotating tooth 6 and the second rotating wheel 8 remains the same, so that the two ends of the cable are subjected to the same force, which can ensure the stability of the torsion work and prevent one end of the cable from being subjected to excessive torque and affecting the accuracy of the detection.

[0038] A sleeve 9 is fixedly mounted on the second rotating tooth 6 and the second rotating wheel 8. A positioning groove connected to the circuit is opened at one end of the sleeve 9. A positioning hole is opened on the sleeve 9 and the sleeve 9 is connected to the circuit by locking and fixing it through an adjusting bolt 10.

[0039] Specifically, the positioning groove on the sleeve 9 is provided to provide a movable space for the line to pass through. In conjunction with the adjusting bolt 10, it can adaptively clamp and fix cables of different diameters, thereby facilitating subsequent torsional and tensile testing.

[0040] The output shaft of the first motor 3 can simultaneously drive the rotation of the first rotating tooth 4 and the first rotating wheel 5. Through the meshing transmission of the gears and the transmission action of the conveyor belt 7, it can not only drive the reverse rotation between the second rotating tooth 6 and the second rotating wheel 8, but also enable the two to drive the sleeve 9 to maintain the same speed.

[0041] The tensile detection mechanism 11 includes a second motor 12 fixed on the base plate, the output shaft of the second motor 12 is connected to a screw shaft 13 distributed along the length direction of the base plate, and a slider 14 is spirally transmitted on the screw shaft 13. The top of the slider 14 is connected to an arc-shaped pull hook 16 placed on the line through a cylinder 15.

[0042] Specifically, since the spiral transmission has a self-locking property, the screw shaft 13 can drive the detection mechanism on the slider 14 to stop at the corresponding position during the rotation process, and the arc-shaped pull hook 16 on the cylinder 15 can effectively detect the downward stretching of the cable to obtain the tensile strength data of the cable. In addition, the fixing brackets 19 around the bottom end of the water tank 18 and the slider 14 are connected by a synchronization rod, that is, the fixing bracket 19 at the bottom of the water tank 18 is in active contact with the bottom plate, and the slider 14 can drive the synchronous movement of the water tank 18 during the movement, and rollers can be adaptively added to the bottom plate to help the water tank 18 move by increasing the friction resistance, and the friction damage is small, thereby improving the service life of the device.

[0043] The outer wall edge of the screw shaft 13 is provided with a limit groove placed on the bottom plate, the piston rod on the cylinder 15 and the arc-shaped hook 16 are connected by a lifting rod 17, the outside of the lifting rod 17 is placed in the water tank 18, and the bottom end of the water tank 18 is connected to the bottom plate through a fixing frame 19 on all sides. The lifting rod 17 and the push plates 20 at both ends of the bottom of the inner wall of the water tank 18 are connected by a first swing rod 21, and the push plate 20 and the baffle 23 on the first storage box 22 are connected by a second swing rod 24.

[0044] The top of the push plate 20 is triangular in shape, and the baffle plate 23 is movably limited and connected to the slide groove on the outer wall of the first storage box 22, and the outer wall of the baffle plate 23 is provided with a filter hole 38 adapted thereto. Both ends of the outer wall of the first storage box 22 are integrally formed with an L-shaped bent plate 25 connected to the top support of the water tank 18, and a handle 26 placed on the first storage box 22 is provided between the L-shaped bent plates 25.

[0045] The structural design of the first storage box 22 and the second storage box 28 is as follows:

[0046] The first storage box 22 adopts a handle-type lifting structure and is arranged on the side wall of the water tank 18. The second storage box 28 is a movable pull-out design and is arranged at the bottom of the water tank 18. Since the lifting rod 17 connected to the cylinder 15 runs through the water tank 18, the above-mentioned structural design can avoid interference between the transmission parts during movement. On the other hand, it can facilitate personnel operation and convenient replacement of clean activated carbon particles.

[0047] The shielding plate 23 on the first storage box 22 is provided with a filter hole 38, so that when the push plates 20 at both ends move outward, the shielding plate 23 can be driven to move upward, and the activated carbon that adsorbs impurities can be pushed into the first storage box 22. At the same time, an inclined surface 27 is provided at the opening of the first storage box 22, which can quickly and effectively push the activated carbon into the first storage box 22. During the centering movement of the push plate 20, the shielding plate 23 moves downward and can close the opening.

[0048] During the tensile test, the second motor 12 cooperates with the arc-shaped hook 16 on the cylinder 15 to perform tensile strength testing on cables at different positions. In addition, when the arc-shaped hook 16 moves downward, it can drive the corresponding position of the cable to move into the water tank 18, so that the cable sealing test can be carried out at the same time. In order to allow the reuse of the water body, a large amount of impurities will be attached to the water body during high-frequency sealing testing. During the up and down movement of the lifting rod 17, the pushing plates 20 at both ends can be driven to move horizontally back and forth. During the movement of the pushing plates 20, the activated carbon after adsorbing impurities can be pushed into the first storage box 22 and the second storage box 28. The first storage box 22 is a lifting movable design, and the second storage box 28 is a pull-out movable design. Moreover, the shielding plate 23 on the first storage box 22 can effectively close the opening when the impurities are pushed into the box body under the rotation connection action of the second swing rod 24, and open the opening during the pushing process. This can facilitate personnel operation on the one hand, and avoid motion interference between structural parts on the other hand, thereby ensuring the stability and safety of the device.

[0049] The shielding plate 23 on the first storage box 22 is actually a protrusion mounted on the second swing rod 24 by a rotational connection, and the protrusion on the shielding plate 23 is connected to the shielding plate 23 by a detachable installation method, such as a bolt assembly and a positioning pin locking and fixing method, so that the protrusion can be quickly separated from the shielding plate 23, thereby facilitating the lifting of the first storage box 22 by the handle 26, thereby facilitating subsequent cleaning work, and the filter hole 38 on the shielding plate 23 can automatically discharge the water during the upward lifting of the first storage box 22.

[0050] In the present invention, the tensile strength and torsional strength of the cable can be tested separately, and the torsional strength can be tested simultaneously with the tensile strength of the wire and cable without changing the equipment, thereby improving the testing efficiency.

[0051] Specifically, activated carbon particles have a low density and feel light to the touch. When placed in water, they will float on the water surface for a period of time, and then gradually sink to the bottom of the water as the adsorption of water molecules reaches saturation. The floating and sinking process can effectively expand the contact area with impurities in the water and improve the adsorption and purification effect.

[0052] An inclined surface 27 is connected to the opening of the outer wall of the first storage box 22 near the baffle plate 23. Both ends of the first swing arm 21 are installed on the lifting rod 17 and the push plate 20 by a rotating connection. Both ends of the second swing arm 24 are installed on the push plate 20 and the baffle plate 23 by a rotating connection. Second storage boxes 28 are provided on both sides of the bottom end of the water tank 18, which are symmetrical with the center of the lifting rod 17. The second storage box 28 is a movable pull-out design.

[0053] An automatic detection device for aircraft engine lines also includes a water purification mechanism 29, which includes a bracket fixed at both ends of a lifting rod 17. The extended end of the top of the bracket passes through a shell 30 and extends to a first gear plate 31 inside the shell 30. The outer wall of the first gear plate 31 is engaged with a second gear plate 33 that moves in the opposite direction through a central rotating tooth 32. The top ends of the first gear plate 31 and the second gear plate 33 are correspondingly connected to a first baffle 34 and a second baffle 35.

[0054] Specifically, the connection between the shell 30 and the water tank 18 is connected by locking and fixing with a positioning pin. The first baffle 34 and the second baffle 35 are connected with a movable opening near the guide tube 36. The guide tube 36 is distributed obliquely. The outer wall edge of the center rotating tooth 32 is provided with a rotating groove placed on the inner wall of the shell 30. One end of the guide tube 36 extends into the water tank 18, and the other end extends to the material box 37. Activated carbon particles are stored in the material box 37, and the material box 37 and the water tank 18 are connected by a crossbeam. A quantitative cavity is formed between the first baffle 34, the second baffle 35 and the inner wall of the guide tube 36. A guide groove connected to the activated carbon particles is provided in the guide tube 36. As the first baffle 34 moves upward and contacts the top of the inner wall of the guide tube 36, the second baffle 35 moves downward and closes the movable opening on the guide tube 36.

[0055] In addition, the fixing frames 19 around the bottom end of the water tank 18 and the slider 14 are connected by a synchronization rod. As the slider 14 moves, the synchronization rod drives the water tank 18 to move horizontally synchronously. The up and down staggered movement between the first baffle 34 and the second baffle 35 can play a better quantitative role in the downward movement of the activated carbon particles in the guide tube 36. The automation effect is good and no additional power source is required.

[0056] Activated carbon particles for adsorbing impurities are placed in the material box 37. During the movement of the lifting rod 17, the first gear plate 31 on the bracket can be driven to move synchronously. Under the gear meshing transmission, the first baffle 34 and the second baffle 35 can move up and down in an interlaced manner, thereby effectively blocking the continuously descending activated carbon particles. Moreover, during the blocking process, the quantitative cavity formed between the first baffle 34 and the second baffle 35 can automatically quantify the activated carbon, preventing the particles from continuously falling into the water tank 18, avoiding the excessive use of activated carbon particles, effectively utilizing resources, and having a strong automation effect.
