Embodiment 1

[0036] figure 1 A schematic structural diagram of the deep-sea robot power supply system provided by this embodiment is shown. In this embodiment, the deep-sea robot is preferably an unmanned remotely operated vehicle (ROV).

[0037] Such as figure 1 As shown, the deep-sea robot power supply system provided by this embodiment preferably includes: a surface power supply device 101 and an underwater repeater 102 . Wherein, the water surface power supply device 101 is arranged on the ship, and is connected to the onboard generator 100 on the ship, so that the low-voltage alternating current provided by the onboard generator 100 can be transmitted to the water surface power supply device 101 . Certainly, in other embodiments of the present invention, according to actual needs, the onboard generator 100 can also be used as a component of the surface power supply device 101 , and the present invention is not limited thereto.

[0038] In this embodiment, the surface power supply d...

Embodiment 2

[0048] figure 2 A schematic structural diagram of the deep-sea robot power supply system provided by this embodiment is shown.

[0049] Such as figure 2 As shown, similar to the deep-sea robot power supply system provided in Embodiment 1, the deep-sea robot power supply system provided in this embodiment preferably also includes: a surface power supply device 101 and an underwater repeater 102 . Wherein, the structure of the water surface power supply device 101 and the principle of realizing its functions are the same as those described in the first embodiment above, so the relevant content of the water surface power supply device 101 will not be repeated here.

[0050] For some unmanned remotely controlled submersibles (ROVs), the interior is equipped with an underwater inverter circuit connected to the motor. Such as figure 2 As shown, the unmanned remote control vehicle ROV includes a plurality of motors (such as the first motor 104a, the second motor 104b, ..., the ...

Embodiment 3

[0054] image 3 A schematic structural diagram of the deep-sea robot power supply system provided by this embodiment is shown.

[0055] In this embodiment, the deep-sea robot is preferably an autonomous underwater vehicle (Autonomous Underwater Vehicle, AUV for short). Autonomous underwater vehicles are usually cable-free underwater robots, which can have the advantages of large range of activities, good maneuverability, safety, and intelligence. For this type of underwater robot, similar to the deep-sea robot power supply system provided in Embodiment 1, the deep-sea robot power supply system provided in this embodiment preferably also includes: a surface power supply device 101 and an underwater repeater 102 . Wherein, the structure of the water surface power supply device 101 and the principle of realizing its functions are the same as those described in the first embodiment above, so the relevant content of the water surface power supply device 101 will not be repeated he...

Abstract

The invention discloses a deepwater robot power supply system, which comprises a water surface power supply device and an underwater repeater, wherein the water surface power supply device is arrangedon a ship and processes low-voltage alternating current provided by an on-board electric generator arranged on the ship to obtain corresponding high-voltage direct current; and the underwater repeater is used for converting the high-voltage direct current transmitted from the water surface power supply device, and transmitting electric energy obtained by conversion to a deepwater robot. Comparedwith an existing power supply system that three-phase alternating current is directly adopted to supply power to a motor in the deepwater robot, the system disclosed by the invention is changed into two-line power supply from three-phase power supply, in addition, only active power required by the motor in the deepwater robot needs to be transmitted, so that the amount of the traverses of a wholeumbilical cable is reduced, meanwhile, the diameter of the traverse is reduced, and the weight and the cost of the umbilical cables are greatly lowered.

Description
