Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] Aiming at the deficiencies in the current prior art, the present invention aims to provide a deep-sea operation ROV thruster system structure, which can be used for the operation type ROV and observation type ROV with a diving depth within 1500 meters, especially for the larger power The operational ROV performs underwater operations. The system can upload the status data of the proportional valves of each thruster of the underwater ROV system in real time according to the work and control needs of the ROV system.

[0033] The propulsion system is a large-scale operation ROV propulsion system based on hydraulic propulsion. It is divided into four parts: hydraulic system, communication system, thrust distribution system, and drive system. The hydraulic oil enters the propeller, which drives the hydraulic motor of the propeller to rotate and output powe...

Abstract

The invention discloses a deep-sea working ROV (Remotely Operated Vehicle) propeller system. An ROV controller can generate a speed control instruction of six degrees of freedom according to the current motion state of an ROV; a communication unit adopts a TCP (Transmission Control Protocol) / IP (Internet Protocol) network communication mode and transmits the speed control instruction generated by the ROV controller to a thrust distribution unit; a propeller unit comprises four horizontal propellers and three vertical propellers; the thrust distribution unit decomposes the instruction according to the received speed control instruction, and the obtained thrust values of all the propellers are transmitted to a driving unit; the driving unit outputs corresponding voltage signals according to the received thrust values and transmits the voltage signals to a propeller proportional valve, and opening and closing of the propeller proportional valve is adjusted; a hydraulic unit transmits hydraulic oil to the propeller unit through the propeller proportional valve. The deep-sea working ROV propeller system can improve the execution capability and efficiency of a propelling system.

Description

technical field [0001] The invention belongs to the technical field of underwater robots, and in particular relates to a deep-sea operation type ROV thruster system. Background technique [0002] The ocean is an area that has not yet been developed on a large scale, especially the complex environment of the seabed and the rich and diverse natural resources in the deep sea. In work research. Although the ocean development technology is not yet fully mature, underwater robots have achieved extensive scientific research value, engineering experience, and economic benefits in deep-sea operations. The research on underwater robots also provides an important research direction for the marine sector of national defense construction. There are two types of underwater robots: one is autonomous, called AUV; the other is remotely controlled, called ROV. ROV is a kind of robot that the operator remotely controls the robot to work and explore underwater through cables. The ROV propuls...
