Description

technical field

[0001] The invention belongs to the technical field of remote-controlled unmanned submersibles, and in particular relates to a vector control device, an underwater vector thruster and a remote-controlled unmanned submersible. Background technique

[0002] The ocean is a very important strategic resource of the country. At the moment when the survival resources are increasingly depleted, marine resources are particularly important. Due to the harsh and dangerous underwater environment and the limited depth of diving, various submersibles have become an important tool for developing the ocean. ROV (Remotely Operated Unmanned Vehicle) is an important equipment for marine observation and development. It is not only of great significance in the exploration of marine resources, but also has very important practical significance in military and scientific research. Because ROV has outstanding features such as safety, economy, high efficiency and large operating dep...

Embodiment Construction

[0041] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0042] Such as Figure 1-Figure 3 As shown, the vector control device for controlling the underwater vector thruster of the remotely controlled unmanned submersible includes a sealed cabin, a power supply unit 10 located in the sealed cabin, a control unit 8 and two sets of rotary drive units;

[0043]The airtight cabin includes a housing 4 and an airtight hatch 3 fixedly mounted on the upper end of the housing 4 to facilitate installation and maintenance of components in the airtight cabin. A static sealing ring 7 is arranged between the airtight hatch 3 and the housing 4 . Coaxial holes are respectively provided on the side walls of the left and right sides of the housing 4; the coaxial holes are stepped holes, which are successively the first stepped hole, the second stepped hole and the third stepped hole, and The diameters of the three holes decrease s...
