Gas-liquid mixed passive buoyancy compensation method for profile float

PendingCN122126411AWaterborne vesselsBuoysBuoyancy regulationOcean observations
This invention discloses a passive buoyancy compensation method using gas-liquid mixing for profiling buoys, belonging to the field of buoyancy adjustment technology for marine observation buoys. This method constructs a passive buoyancy compensation system containing gas and liquid chambers, and adjusts the gas-liquid volume ratio to achieve linear and continuous adjustment of the system's equivalent compressibility coefficient, dynamically matching the compression characteristics of seawater at different depths. A mathematical model of the overall force on the buoy is established to determine system design parameters. Sensors are deployed to collect buoy depth and axial acceleration data, calculate motion parameters, predict and estimate the depth, and compare it with the target depth. When the deviation threshold is exceeded, an active fine-tuning judgment process is initiated. Active adjustment is disabled during the inertial-dominated phase, and during the non-inertial phase, the controller sends a fine-tuning command to the active buoyancy system to execute reverse buoyancy adjustment. The passive buoyancy compensation method using gas-liquid mixing provided by this invention can achieve low-power buoyancy control with passive adjustment as the primary method and active adjustment as a secondary method, effectively extending the underwater operational life of the buoy.

This invention belongs to the field of water conservancy engineering technology and discloses an anti-collision navigation buoy for water conservancy projects. It includes a buoy body and photovoltaic panels and a counterweight ring installed above and below it, respectively. It also includes a line-laying protection mechanism installed inside the buoy body, with a plurality of protective springs arranged in a ring array around the outer periphery of the buoy body. The above solution works by having the buoy body contact the protective springs upon impact with a ship, compressing and buffering them. When the ship pushes the buoy body, the winding roller rotates to release the extension cable. The rotation of the winding roller is then reduced by a planetary reducer, driving a transmission disc to rotate and compressing a large coil spring. The transmission disc, through the planetary reducer, causes the winding roller to rotate in the opposite direction until the extension cable is completely retracted, returning the buoy body to its original position. This solves the problem of anchor chain breakage or anchor dragging when the buoy is impacted by a ship.
