Technical Field

[0001] The invention relates to an energy self-supply system and belongs to the technical field of water flow power generation. Background Art

[0002] During the navigation of ships in the waterway, some ships have a series of illegal and irregular behaviors such as speeding, over-depth, entering prohibited navigation areas, illegal parking, illegal dumping of garbage, illegal water operations, etc. At present. In terms of water supervision, it is mostly dependent on patrol boats and onshore patrol personnel for inspection. However, this method has the disadvantages of large terrain restrictions, small supervision scope and supervision time domain coverage, and inability to deal with illegal and irregular ships in a timely manner; and some new waterway navigation supervision devices, although they have greatly improved in unmanned intelligence compared with traditional methods, their power supply often relies on battery power supply or shore-based power supply, which is not conducive to the long-term operation of the device; for example: the publication number is CN114495579A, and the name of the invention is a supervision device and service method for navigable waterways, which uses microprocessor + AIS transceiver module and other supervision modules for waterway supervision, and uses power management module + battery for power supply. However, the energy of this design relies on battery power supply, and patrol personnel need to replace the battery regularly, and its installation and layout location is limited.

[0003] Therefore, it is urgent to propose an energy self-supply system for water supervision and law enforcement security guards to solve the above-mentioned technical problems. Summary of the invention
