step one, sealing detection: the surface detection ring 13 transmits a first signal to the swing door motor, so that the rotating shaft 49 rotates, the detection oil 51 can flow into the inner hydraulic cavity 11 through the swing door cavity 48, if leakage occurs due to damage of the sealing gasket 39, the hydraulic oil can flow downwards through the sealing gasket 39, meanwhile, the detection oil 51 can also flow downwards through the sealing gasket 39, so that the detection oil 51 can flow into the bottom wall of the detection cavity 42 from the top port of the detection cavity 42, the identifier 43 can identify the detection oil 51, the identifier 43 transmits an alarm signal to the third power supply, the seal alarm 44 gives an alarm, and a worker can directly obtain an oil leakage point according to the seal alarm 44;
step two, outer wall detection: meanwhile, the surface measuring ring 13 transmits a second signal to the sound wave power supply, so that the sound wave power supply can be turned on, the sound wave device 37 emits ultrasonic waves to the outer peripheral surface of the hydraulic shell 10, then the outer peripheral surface of the hydraulic shell 10 can reflect the ultrasonic waves to the sound wave device 37, and meanwhile, the lifting motor is turned on, so that the lifting screw 35 rotates, and the lifting ring 36 can slide up and down;
when there is no crack on the outer peripheral surface of the hydraulic shell 10, in the process of moving the lifting ring 36 up and down, the difference between the transmitting time and the receiving time of the ultrasonic wave is not changed, if there is a crack on the outer peripheral surface of the hydraulic shell 10, when the ultrasonic wave is transmitted to the crack, the difference between the transmitting time and the receiving time of the ultrasonic wave is increased, and the larger the difference value is, the deeper the crack is, so that the depth of the crack can be determined according to the difference value, and meanwhile, the acoustic wave device 37 transmits an alarm signal to the second power supply to turn on the second power supply, so that the crack alarm 45 gives an alarm.
Automatic oil supplement: when the oil leakage occurs in the damper, the oil level of the hydraulic oil in the inner hydraulic cavity 11 is lowered until the oil level is lower than the bottom surface of the surface measuring ring 13;
the face measuring ring 13 transmits an oil supplementing signal to the rotating motor, so that the rotating motor can be started, the rotating shaft 21 rotates, the closing plate 17 can rotate along with the rotating shaft 21 until the rotating shaft 21 rotates ninety degrees, meanwhile, the oil supplementing plate 20 can slide downwards through the oil supplementing spring 19, so that the compensation oil 23 can be downwards extruded through the hydraulic plate 29, the compensation oil 23 can downwards flow into the inner hydraulic cavity 11 through the oil supplementing port 15 until the oil level is higher than the top surface of the face measuring ring 13, the rotating motor is started again, the rotating shaft 21 rotates ninety degrees again, and the compensation oil 23 can be prevented from flowing into the inner hydraulic cavity 11.
Oil supplement alarm: when the compensation oil 23 all flows into when interior hydraulic pressure chamber 11, the butt is bought with fixed disk 14 top to oil supplementing plate 20 bottom surface, thereby oil supplementing plate 20 can give control signal transmission first power, thereby can make first power is opened, thereby can make oil supplementing warning indicator 28 sends out the warning, thereby pass through oil supplementing warning indicator 28 remind the staff in time to in the top chamber 18 pour into compensation oil 23.
It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
