Problems solved by technology
When the underwater device is running underwater, its underwater battery pack is also easily corroded. Once corroded, it will seriously affect the normal operation of the battery pack, thereby affecting the safety of the underwater device.
[0003] However, the current underwater power supply equipment generally uses battery packs. Most of the battery packs on the existing market have simple packaging, weak corrosion resista

The invention relates to a maintenance-free underwater power supply system, which comprises an enclosed pressure-proof box body, wherein a plurality of batteries and a battery management system are arranged in the box body; the plurality of batteries are connected in series or in parallel; the battery management system manages the plurality of batteries; the box body is provided with an input interface and an output interface; the output interface is used for supplying electricity to external equipment; and a hydraulic power generation device is arranged and charges the plurality of batteries through the input interface. An impeller is impacted by hydraulic power; and the impeller drives a generator to generate electricity and charges the batteries of the power supply system, so that resources are fully utilized and saved; electricity can be continuously supplied to equipment; frequent maintenance by a worker is not needed; and the labor cost is reduced. The maintenance-free underwater power supply system can be protected in manners of sacrificial anode and cathode protection, anti-corrosion paint spraying and the like; and the anti-corrosion performance of the power supply system is significantly improved.
Description
technical field [0001] The invention relates to underwater power supply equipment. Background technique [0002] Existing underwater devices are generally used in marine scientific research, property rescue, exploration and mining, scientific detection, equipment maintenance, search and rescue, submarine cable maintenance, underwater tourism, etc., and can also be used for military purposes. When carrying out underwater activities, due to the high pressure, the equipment on the underwater device must have strong compressive, waterproof and anti-corrosion capabilities. As the main energy storage equipment loaded with batteries, the underwater power supply system is an indispensable component of underwater devices, and its performance directly affects the performance of underwater devices. When the underwater device is running underwater, its underwater battery pack is also easily corroded. Once corroded, it will seriously affect the normal operation of the battery pack and f...
