Problems solved by technology

[0003] Due to the low speed of the ROV itself, the process of putting the ROV into the water from the ship, diving the ROV to the estimated depth, especially to the depth required for fixed-point scanning, and recovering the ROV from the water will take a lot of time, every day The time that can actually be used for scanning is very short, resulting in inefficient underwater scanning

Embodiment 1

[0048] figure 1 It is a right side view of an ROV provided by the embodiment of the present invention. The side plates 10 on both sides of the ROV are respectively equipped with wing plates 20, and the wing plates 20 are fixedly connected to the side plates of the ROV through hinges. The hinge axis of the hinge is parallel to the ROV side plate; the hinge axis is axial (such as figure 1 Shown in a) is in the horizontal direction of the ROV along the advancing direction of the ROV (such as figure 1 The first included angle shown in b and the advancing direction) is an obtuse angle; the ROV is connected to the ship through the umbilical cable 30, and the ROV is towed by the ship in the water through the umbilical cable 30, and the umbilical cable 30 Including a power cord, used to provide the required power for the ROV; the wing 20 has a first working position, the first working position is specifically the main working surface of the wing and the ROV side plate The second inc...

Embodiment 2

[0140] Optionally, the embodiment of the present invention also provides a motor and a connection device to help the flaps to accurately switch freely between the first working position and the second working position during the working process.

[0141] A connecting device is installed on the wing plate 20, and the other end of the connecting device is connected with the motor on the ROV,

Abstract

The embodiment of the invention discloses an ROV (remote operated vehicle) and an underwater scanning method. Side panels at two sides of the ROV are respectively provided with a wing panel, and a hinge shaft of a hinge part for fixing the wing panels is parallel to the ROV side panel; a first angle formed between the axial direction of the hinge shaft and a horizontal direction along the advancing direction of the ROV is an obtuse angle, the ROV is dragged by a boat in the water by virtue of an umbilical cable, the umbilical cable comprises a power supply wire, when the wing panels stay at a first workstation, during the process for dragging the ROV in the water, the wing panels acquire a vertical-downward settling force, and the ROV is enabled to be settled in the water during the dragging process; when the umbilical cable is submerged in the water, a vertical upward floating force is acquired; when the settling force is identical to the floating force, the ROV reaches a preset working depth to carry out the underwater scanning. When the ROV is dragged, the ROV can be submerged into the water under the action of the side wings so as to reach the preset working depth, so that the scanning efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of underwater operations, in particular to an ROV and an underwater scanning method. Background technique [0002] Unmanned remotely operated vehicle (Remote Operated Vehicle, ROV) is mainly used to perform underwater observation and scanning tasks. However, due to the limitation of ROV power, its own speed is not high, and generally the highest speed can only reach about 2 knots. A traditional underwater scanning method can be to use a ship to carry an ROV to the scanning area. After stopping the ship, the ROV's own propulsion system will be used as a power source to control the ROV to dive to a shallower depth and sail at this depth for a rough scan. . If a suspicious point is found during the rough scan, a detailed fixed-point scan can be performed on the suspicious point. The fixed-point scan needs to control the ROV to dive to a deeper depth to get closer to the suspicious point, so as to obtain more detailed d...
