Automatic control system and method for underwater posture adjustment of immersed tube
The invention discloses an automatic control system and method for underwater posture adjustment of an immersed tube. The system comprises an immersed tube posture acquisition module, an immersed tube remote control module and an immersed tube posture adjustment module; the immersed tube posture acquisition module and the immersed tube posture adjustment module are in communication connection with the immersed tube remote control module; the immersed tube posture acquisition module acquires posture information of the immersed tube; the immersed tube posture adjustment module comprises a ballast water tank unit and a variable frequency winch unit; the immersed tube remote control module receives the posture information of the immersed tube and controls a ballast water pump, an electromagnetic valve and at least one water valve in the ballast water tank unit to be opened according to the posture information of the immersed tube so as to adjust the ballast gravity of the immersed tube; and meanwhile, a variable frequency winch is controlled to work so that the immersed tube can be immersed at a constant speed, in the abovementioned way, the self weight of the immersed tube is controlled by adjusting the water injection amount and the water discharge amount in a water tank, and constant-speed sinking of the immersed tube is controlled in an auxiliary mode through cooperation of the variable frequency winch unit. The immersed tube sinking and floating postures are accurately controlled, and the immersed tube sinking and floating posture adjustment efficiency is improved.
本发明公开了一种沉管的水下姿态调整自动控制系统和方法。该系统包括沉管姿态获取模块、沉管远程控制模块及沉管姿态调整模块；沉管姿态获取模块与沉管姿态调整模块分别与沉管远程控制模块通信连接；沉管姿态获取模块获取沉管的姿态信息；沉管姿态调整模块包括压载水箱单元及变频绞车单元；沉管远程控制模块接收沉管的姿态信息并根据沉管的姿态信息控制压载水箱单元中压载水泵、电磁阀及至少一个水阀打开以调节沉管的压载重力；同时控制变频绞车工作以使沉管匀速沉放，如此通过调节水箱内的注水量和排水量控制沉管的自重，并通过变频绞车单元配合辅助控制沉管的匀速下沉；实现了对沉管沉放、上浮姿态的精准控制，提高沉管沉放、上浮姿态调整的效率。
