[0013] The present invention also discloses a deep-sea submersible fault monitoring device, which adopts the above-mentioned deep-sea submersible fault monitoring method, and includes the following steps:

[0014] S1. First, start the first driving motor. The output end of the first driving motor drives the first reciprocating lead screw to rotate, so as to drive the guide block to drive the ultrasonic flaw detector to move vertically to a specified position through the sliding frame. Then, the ultrasonic flaw detector is used to monitor the equipment to be monitored. Start the second driving motor. The output end of the second driving motor drives the second reciprocating lead screw to rotate, so as to drive the sliding seat to drive the ultrasonic flaw detector to move horizontally, so as to monitor the equipment at different positions;

[0015] S2. After the ultrasonic flaw detection sensor moves horizontally and vertically to the specified position, start the third drive motor. The output end of the third drive motor drives the rotary push plate to drive the power column to rotate, thereby pushing the loop frame to drive the H-shaped slide seat to move up and down reciprocally through the special-shaped rod, so as to drive the position of the ultrasonic flaw detection sensor to be finely adjusted, thereby expanding the monitoring range of the ultrasonic flaw detection sensor for the equipment;

[0016] S3. While the H-shaped slide seat moves upward, it drives the first spur gear to drive the worm to rotate through the first rack, thereby driving the worm wheel to drive the connecting swing block to rotate through the coupling shaft, and then pushing the ratchet to rotate through the first ratchet tooth. When the ratchet rotates, it drives the second ratchet tooth to drive one end of the torsion spring to rotate. When the ratchet stops rotating, the torsion spring drives the second ratchet tooth to reset, so that the second ratchet tooth meshes with the ratchet to limit the ratchet. When the H-shaped slide seat resets, the first rack drives the first spur gear to rotate in the reverse direction, thereby driving the connecting swing block to drive the first ratchet tooth to reset, thereby realizing the function of driving the first rotating shaft to drive the ultrasonic flaw detection sensor to rotate intermittently through the turntable, thereby expanding the monitoring range of the ultrasonic flaw detection sensor for the equipment, enabling the ultrasonic flaw detection sensor to evenly monitor a part of the equipment, and thus improving the accuracy of monitoring the equipment;

[0017] S4. While the coupling shaft rotates, it drives the second spur gear to rotate, thereby driving the second rack and the first ratchet tooth to drive a second U-shaped connecting block to move towards the sliding seat respectively, so that the two rotating wheels are attached to both sides of the sliding seat, thereby correcting the position of the H-shaped slide seat, and thus improving the accuracy of the ultrasonic flaw detection sensor for monitoring the equipment;

[0018] S5. While the second U-shaped connecting block drives the rectangular connecting frame to approach the sliding seat, it drives the fourth rack to move through the L-shaped power rod, thereby driving the third spur gear to drive the swing block to rotate through the third rotating shaft. When the two swing blocks are unfolded and attached to the outer walls of the two rectangular positioning blocks, the position of the sliding seat is calibrated to prevent the position of the sliding seat from shifting, thereby further improving the accuracy of the ultrasonic flaw detection sensor for monitoring the equipment.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By setting up the cooperation of parts such as the first driving motor and the first reciprocating lead screw, the output end of the first driving motor drives the first reciprocating lead screw to rotate, thereby driving the guiding block to drive the ultrasonic flaw detector sensor to move vertically to a specified position through the sliding frame. Then, the ultrasonic flaw detector sensor monitors the equipment to be monitored. Start the second driving motor, and the output end of the second driving motor drives the second reciprocating lead screw to rotate, thereby driving the sliding seat to drive the ultrasonic flaw detector sensor to move horizontally, so as to monitor different positions of the equipment, enabling the staff to accurately determine the fault location of mechanical parts, thus facilitating the staff to carry out repairs;

[0021] 2. By setting up a cyclic displacement mechanism, after the ultrasonic flaw detector sensor moves horizontally and vertically to a specified position, start the third driving motor. The output end of the third driving motor drives the rotary push plate to drive the power column to rotate, thereby pushing the loop-shaped frame to drive the H-shaped sliding seat to move up and down reciprocally through the special-shaped rod, thereby driving the position of the ultrasonic flaw detector sensor to be finely adjusted, so as to expand the monitoring range of the ultrasonic flaw detector sensor for the equipment, and further improve the monitoring accuracy of the equipment;

[0022] 3. By setting up an intermittent positioning auxiliary part, while the H-shaped sliding seat moves upward, it drives the first spur gear to drive the worm to rotate through the first rack, thereby driving the worm wheel to drive the connecting swing block to rotate through the coupling shaft, and then driving the ratchet to rotate through the first ratchet tooth. When the H-shaped sliding seat is reset, the first rack drives the first spur gear to rotate in the reverse direction, thereby driving the connecting swing block to drive the first ratchet tooth to reset, thus realizing the function of driving the first rotating shaft to drive the ultrasonic flaw detector sensor to rotate intermittently through the turntable, so as to expand the monitoring range of the ultrasonic flaw detector sensor for the equipment, enabling the ultrasonic flaw detector sensor to evenly monitor a place of the equipment, thereby improving the accuracy of monitoring the equipment;

[0023] 4. By setting up a limit protector, when the ratchet rotates, it drives the second ratchet tooth to drive one end of the torsion spring to rotate. When the ratchet stops rotating, the torsion spring drives the second ratchet tooth to reset, so that the second ratchet tooth meshes with the ratchet to limit the ratchet, thus preventing the ratchet from rotating;

[0024] 5. By setting up a deviation correction protection unit, when the coupling shaft rotates, it drives the second spur gear to rotate, thereby driving the second rack and the first ratchet tooth to drive a second U-shaped connecting block to move towards the sliding seat respectively, so that the two groups of rotating wheels are attached to both sides of the sliding seat, thereby correcting the position of the H-shaped sliding seat, thus improving the monitoring accuracy of the ultrasonic flaw detector sensor for the equipment;

[0025] 6. By setting up a calibration assistor, while the second U-shaped connecting block drives the rectangular connecting frame to approach the sliding seat, it drives the fourth rack to move through the L-shaped power rod, thereby driving the third straight gear to drive the swing block to rotate through the third rotating shaft. When the two swing blocks are unfolded and attached to the outer walls of the two rectangular positioning blocks, the position of the sliding seat is calibrated to prevent the position of the sliding seat from shifting, thereby further improving the accuracy of the ultrasonic flaw detector sensor in monitoring the equipment.

While the H-shaped slider 16 moves upward, it drives the first spur gear 34 through the first rack 35 to drive the worm 33 to rotate, thereby driving the worm gear 32 to drive the connecting swing block 40 to rotate through the coupling shaft 31, and further pushing the ratchet wheel 17 to rotate through the first ratchet tooth 44. When the ratchet wheel 17 rotates, it pushes the second ratchet tooth 45 to drive one end of the torsion spring 47 to rotate. When the ratchet wheel 17 stops rotating, the torsion spring 47 drives the second ratchet tooth 45 to reset, so that the second ratchet tooth 45 meshes with the ratchet wheel 17 to limit the ratchet wheel 17. When the H-shaped slider 16 resets, the first rack 35 drives the first spur gear 34 to rotate in the reverse direction, thereby driving the connecting swing block 40 to drive the first ratchet tooth 44 to reset, thus realizing the function of driving the first rotating shaft 15 to drive the ultrasonic flaw detector sensor 11 to rotate intermittently through the turntable 10, thereby expanding the monitoring range of the ultrasonic flaw detector sensor 11 for the equipment, enabling the ultrasonic flaw detector sensor 11 to evenly monitor a part of the equipment, and thus improving the accuracy of the equipment monitoring;

[0053] S4. While the coupling shaft 31 rotates, it drives the second spur gear 38 to rotate, thereby driving the second rack 36 and the first ratchet tooth 44 to drive a second U-shaped connecting block 24 to move towards the sliding seat 12 respectively, so that the two rotating wheels 26 are attached to both sides of the sliding seat 12, thereby correcting the position of the H-shaped slider 16, and thus improving the accuracy of the ultrasonic flaw detector sensor 11 for equipment monitoring;

[0054] S5. While the second U-shaped connecting block 24 drives the rectangular connecting frame 25 to approach the sliding seat 12, it drives the fourth rack 50 to move through the L-shaped power rod 27, thereby driving the third spur gear 49 to drive the swing block 29 to rotate through the third rotating shaft 48. When the two swing blocks 29 are unfolded and attached to the outer walls of the two rectangular positioning blocks 22, the position of the sliding seat 12 is calibrated to prevent the position of the sliding seat 12 from shifting, and thus further improving the accuracy of the ultrasonic flaw detector sensor 11 for equipment monitoring.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
