Description
Technical Field
The invention relates to the technical field of monitoring of the health state of underwater metal structures, in particular to an on-line monitoring system for the running state of a ship lock anti-arc door and a working method thereof.
Background
The ship lock anti-arc door works in deep water for a long time, and the sealing between the bottom water stop plate and the rubber or steel water stop plate arranged on the bottom sill embedded part is mainly realized by the combined action of the gravity and the water pressure of the anti-arc door body. Under the traditional mode, the hydraulic pull rod for controlling the opening and closing of the anti-arc door is provided with displacement calibration, and the stroke of the hydraulic pull rod is restrained mainly according to the reading of the displacement calibration in the process of operating the opening and closing of the anti-arc door, so that the opening and closing degree of the anti-arc door is controlled. The precise full closing of the anti-arc door (i.e., the closed position of the anti-arc door is in the full closing position) is difficult to achieve by the traditional method under the influence of the gravity of the anti-arc door, the high water head water pressure, the quaternary water level change and other factors. In the actual operation process, the phenomenon that the water stop is not tight or the closing overshoot is generated due to the fact that the closing position of the anti-arc door cannot be accurately controlled sometimes occurs. If the anti-arc door is not closed in place, the anti-arc door can leak due to the fact that water is not tight; if the anti-arc door is closed and overshot, destructive damage is gradually caused to the sill embedded part, so that leakage is caused. Under the continuous action of high-head water pressure, leakage can cause the anti-arc door to generate additional harmful vibration, and if the vibration is too large, the anti-arc door shaft is possibly broken and the like to cause serious damage, thereby generating huge accident potential. Once an accident occurs on the anti-arc door, the navigation safety is seriously influenced, and the severe social influence and the great economic loss are caused. Therefore, in the process of closing the ship lock anti-arc door, the position of the door body is accurately and precisely judged by using the underwater metal structure (here, the rigid structure made of metal materials such as the anti-arc door) health state monitoring technology, and the method has important practical significance for ensuring the health working state of the anti-arc door and improving the running reliability of the anti-arc door.

The embedded processor module (6) receives the signals transmitted by the real-time acquisition and control module (5), processes the vibration signals, assists in judging whether water leakage occurs or not, and remotely monitors whether the working state of the anti-arc door is safe or not; at the same time, comparing the angle values acquired in real timeStandard angle of the hydraulic hoist of the arc-resistant door, which is measured in advance, when the hydraulic hoist of the arc-resistant door is closed>If->At->Within the range of (2), then +.>Assign->As the angle when the hydraulic hoist of the anti-arc door is closed; after the hydraulic hoist of the anti-arc door is closed and the received real-time acquisition angle is stable, the embedded processor module (6) determines that the acquisition angle value at the moment is the full closing of the anti-arc door at the momentAngle of bit->Comparison->Standard angle with anti-arc door in fully closed position +.>If->At->If within the range of (2), the comparison result is "normal", if +.>Not at->If the range of the data center is abnormal, the embedded processor module (6) immediately sends an early warning signal to the data center (9); the angle stabilization means that the measured value of the angle only fluctuates in the thousandth position;
meanwhile, by combining real-time water pressure information, after the hydraulic hoist of the anti-arc door is determined to be closed, the inertial buffering drop of the anti-arc door is obtained through calculation:
Wherein,is the radius of the anti-arc door->Is the angle of the hydraulic hoist of the anti-arc door when being closed, < + >>The angle of the anti-arc door when reaching the full closing position;
the embedded processor module (6) obtains the angle of the anti-arc door hydraulic hoist when closingTimely feeding back to a real-time acquisition and control module (5);
d3, remote data transmission
The embedded processor module (6) transmits the data to the real-time acquisition and control module (5) and simultaneously obtains the angle of the anti-arc gate hydraulic hoist when being closedAngle of full closing position of anti-arc door +.>And inertial buffer drop of anti-arc door +.>The angle information, the vibration information and the water level information which are received in real time are transmitted to a remote transmission module (8) together, and are uploaded to a data center (9) through the remote transmission module (8);
E. the anti-arc door control unit (7) controls the switch of the hydraulic hoist of the anti-arc door
When the real-time acquisition and control module (5) receives the feedback of the embedded processor module (6), the angle of the reverse arc door hydraulic hoist is closedWhen the real-time acquisition and control module (5) sends an anti-arc door hydraulic hoist control signal to the anti-arc door control unit (7) immediately, and the anti-arc door control unit (7) receives the anti-arc door hydraulic hoist sent by the real-time acquisition and control moduleImmediately closing the anti-arc door hydraulic hoist after the control signal;
F. a data center (9) for displaying data
The data center (9) displays and stores the received data sent by the remote transmission module (8) in real time through a menu window for later overhaul reference; if the data center (9) receives the early warning signal sent by the embedded processor module (6), a prompt window is popped up immediately to send out early warning.
