Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0051] like Figure 1-16 As shown, the present invention provides a covert acquisition device for deep-sea environmental information, including a support frame assembly, a main controller assembly, and multiple beacons;
