Description

1. Purpose of the invention The invention serves to provide a compact, modular and automatically activatable underwater system that can be used for warning, signaling, depth positioning and rescue. The module enables both the automatic surfacing of people or objects, as well as the stable holding of objects at a defined water depth and the transmission of radio or acoustic signals underwater. 2. Technical problem The current state of the art does not offer a solution that combines the following functions in a single device: • Automatic activation without user interaction, • stable buoyancy through multiple balloons, • Depth measurement and depth control, • Radio or acoustic communication underwater, • Warning and marking function for divers, • Rescue function for unconscious or distressed persons, • Compact design for universal applications. Existing systems are either simple life jackets, basic buoys, or complex, expensive underwater navigation devices without a buoyancy unit. 3. Technical field The invention belongs to the technical fields: • Underwater safety and rescue technology, • CO2 buoyancy systems, • Diving and water sports equipment, • Underwater communication and warning systems, • Depth measurement and positioning technology. 4. Object of the invention The object of the invention is to provide a multifunctional underwater module that: • can be activated automatically or manually, • reliably brings people or objects to the water's surface, • Holds warning and information signs stably at a defined depth, • Can send and receive underwater radio or acoustic signals, • offers high stability and redundancy through multiple balloons, • compact, robust and cost-effective to manufacture. 5. Solution to the task The task is solved by an underwater module that includes the following components: • a CO2 buoyancy unit with at least one CO2 pressure vessel, • several balloons (preferably three) to generate stable lift, • a pressure or depth sensor to detect the water depth, • a microchip for controlling activation and signal processing, • a radio or acoustic communication unit, • a compact housing that integrates all components. The balloons are automatically filled as soon as the depth sensor detects a critical depth or a radio signal triggers activation. 6. Solution approach of the invention The solution is based on a combination of: • mechanical buoyancy through CO2 balloons, • electronic monitoring of depth, • Radio signaling for communication and remote control, • Modular design that allows for various application scenarios. The multi-balloon configuration creates a three-point stable lift, which ensures both vertical and horizontal stability. 7.
