When the door panel 2 is opened, the inflatable balloon 8 exhausts air, and the convex part 802 contracts into a groove formed by the first pressing block 9 and the second pressing block 10, so that accidental damage is prevented; the hydraulic cylinder 3 pushes the locking assembly 6, so that the hook 601 is lifted upwards and separated from the locking groove 504.
Optionally, the flushing door further comprises a limit stop made of stainless steel, the limit stop is arranged on the outer side of the first pressing block 9 and fixedly welded to the upstream side surface of the door plate 2, and when the door plate 2 is closed in place in a vertical position, secondary limiting is performed by the limit stop, so that the door plate 2 is prevented from excessively extruding the inflatable balloon 8.
Optionally, the inflatable sealing assembly further comprises an inflation control device, the inflation control device comprises an air compressor 15, a first pressure sensor 16, a centralized controller 17 and an air vent pipe, the centralized controller 17 is in communication connection with the air compressor 15 and the first pressure sensor 16, and the air compressor 15 is connected with the first pressure sensor 16 and an inflating nozzle 803 of the inflatable balloon 8 through the air vent pipe, and is used for inflating and deflating the inflatable balloon 8. The centralized controller 17 is a PLC controller.
During the use, angle sensor 14 communication connection integrated control ware 17, air compressor 15 inflates to aerifing sacculus 8 through the pipeline of ventilating, and inflation pressure is detected by first pressure sensor 16 in real time to signal transmission that will detect gives integrated control ware 17, when inflation pressure reachs the setting value, aerifys sacculus 8 complete inflation promptly, and angle sensor 14 also detects door plant 2 and reaches vertical position when, integrated control ware 17 control air compressor 15 stop operation, realizes the sealed effective closed-loop control of washing door. When the door plate 2 is opened, the integrated controller 17 controls the air compressor 15 to perform exhaust contraction on the inflatable balloon 8, the inflatable balloon 8 is made of memory rubber and can be completely contracted into a groove formed by the first pressing block 9 and the second pressing block 10, and therefore the inflatable balloon 8 is reliably protected.
Optionally, the detector 13, the hydraulic cylinder 3, and the locking component of the second locking adjustment mechanism 5 are all connected to the integrated controller 17 in a communication manner, and according to the control method and the steps, when the door panel 2 is opened or closed, the integrated controller 17 controls the movement of the arc-shaped protrusion part 7 by controlling the second hydraulic cylinder 301; the detector 13 transmits a detection signal to the integrated controller 17, and the integrated controller 17 controls the hydraulic oil cylinder 3 and the locking component to close the door panel 2; the integrated controller 17 controls the air compressor 15 to inflate the inflatable balloon 8 and controls the locking component to gradually release the door panel 2 to match the inflation of the balloon.
When the door panel 2 needs to be in the closed state for a long time, the inflatable balloon 8 may leak due to the influence of temperature and the like, so that the pressure is reduced, and the internal pressure of the inflatable balloon 8 needs to be detected periodically. The invention indirectly detects the pressure in the inflatable balloon 8 by utilizing the second locking adjusting mechanism 5, and the specific method is as follows: after the door plate 2 is closed, the inflatable balloon 8 is inflated to complete the sealing between the door plate and the door frame, when the door is closed for a long time, the length of the locking groove 504 is properly reduced by the locking component at regular time, and when the reduced length of the locking groove 504 is within a certain smaller range, the length of the locking groove 504 cannot be reduced continuously, which indicates that the internal pressure of the inflatable balloon 8 is qualified, and the sealing requirement can be met; when the length of the locking groove 504 can be continuously reduced, which means that the internal pressure of the inflatable balloon 8 is too low, and leakage may occur, at this time, the inflation control device only needs to inflate the inflatable balloon 8.
The qualified pressure value inside the inflatable balloon 8 is determined by the door frame of the door panel and the water pressure on the upstream side in practical application, and the pressure value of the balloon corresponding to the reduced length of the locking groove 504 can be determined in advance by experiments.
