[0030] With the continuous advancement of my country's modern new technological innovation, qualitative changes have been achieved in all aspects, especially in the ocean. For offshore, from a military perspective, it is necessary to improve the configuration of the sonar system, such as the sonar system grid layout, to listen and monitor the illegal entry of diving devices (such as Virginia nuclear submarines) of hostile countries; at the same time, in offshore fisheries, the sonar sphere can also be dragged to determine the location of the fish school and form a purse seine operation.

[0031] In this way, using drones to complete the sonar system grid layout and sonar towing purse seine operations is a very good choice; after all, when used on operating platforms such as ships and fishing boats, the aircraft is used in the form of a helicopter, which is convenient and fast; if it is launched into the air like a helicopter platform and then converted into a platform with wingspan - that is, it flies like an airplane; that is, relying on the buoyancy and / or lift clamping generated by the wind, the efficiency can be doubled and the flight distance is guaranteed; not only that, with the help of Beidou navigation and wireless communication, the sonar system grid can be implanted in the ocean surface, including the timely adjustment of the deviation of the position of the ocean current and the towing of sonar to detect the gathering points of fish schools and complete the purse seine operation; in short, it is entirely possible to develop the battery and photovoltaic cell-driven drones with variable driving states that we need to meet the needs of ocean sonar system grid implantation in the sea surface and sonar towing purse seine operations.
