Underwater energy guarantee device

Abstract

The invention relates to an underwater energy guarantee device, which comprises a remote communication module, a path analysis module, a power consumption identification module, a shelter identification module, an ocean current judgment module and a target selection module which are arranged in a ground intelligent management system, the long-distance communication module is used for establishing long-distance communication connection with the unmanned underwater vehicle and the underwater preset energy shelter; the plurality of underwater preset energy shelters are respectively put at different underwater positions, and the underwater preset energy shelters comprise various water-activated batteries with different capacities; and the target selection module is used for selecting a matched underwater preset energy shelter for the unmanned underwater vehicle in a power shortage state. According to the invention, a hierarchical selection mechanism can be adopted to select the underwater preset energy shelter with electric quantity information matching, positioning information matching and ocean current information matching for each unmanned underwater vehicle in a power shortage state, so that the individual charging demand of the power shortage unmanned underwater vehicle and the overall energy-saving demand of the underwater energy guarantee device are both considered.

Description

technical field [0001] The invention relates to the field of underwater energy security, in particular to an underwater energy security device. Background technique [0002] At present, the problem of underwater energy security is mainly solved in two ways. One is to use submarine cables to connect power grids. The advantage is that the power supply is stable and the supply is sufficient. Power generation methods such as power generation and silt power generation ensure power supply. This method has low power generation efficiency, unstable supply electrodes, and it is difficult to provide high-power continuous power supply in the deep sea environment. [0003] In order to ensure the energy supply of equipment such as unmanned underwater vehicles that conduct underwater activities in ocean waters, some underwater energy suppliers use water-activated batteries as energy sources. Water-activated batteries have the following advantages: they can output high-power electricity fo...

Problems solved by technology

[0004] However, even if the water-activated battery is released in a precise and free delivery mode, as a newly developed underwater energy protection device, it still has the following defects: underwater vehicles and other equipment move freely and randomly according to tasks Yes, the position of the underwater preset energy shelter packaged with water-activated batteries originally released is fixed, and there is a contradiction in position between the two; even if the underwater submersible remains in a fixed position underwater, the underwater preset energy shelter No matter how accurate the previously launched position is, under the influence of complex underwater environments such as ocean currents, the underwater position of the shelter will also change, causing the underwater vehicle to gradually move away from the fixed position; in addition, multiple When presetting the energy shelter underwater, if the underwater submersible that needs to be charged chooses a shelter with insufficient fuel ionization or a long path, it is likely to cause a scene where it does not reach the shelter or arrives at the shelter but is not fully charged; and If the underwater submersible that needs to be charged blindly searches for the shelter with the farthest path to perform the charging operation, the power wasted on the longer path is actually a waste of energy for the entire underwater energy protection system
