The invention relates to a gas bag type
underwater depth-control suspension
system which is suitable for a carrying platform for
underwater operation, and belongs to the field of water suspension appliances. The gas bag type
underwater depth-control suspension
system comprises an
actuator, a depth
transducer, a
control system and a power supply. The
actuator comprises an exhaust device, a gas bag, a gas bag connection accessory and an inflation device, wherein the exhaust device is used for exhausting gas in the gas bag and reducing the
buoyancy of a suspension
system body, the gas bag is used for providing the
buoyancy for the system body, the gas bag connection accessory is used for connecting the gas bag with a shell of the suspension system body, and the inflation device is used for inflating the gas bag and increasing the
buoyancy of the suspension system body. The depth
transducer is used for measuring the underwater depth of the suspension system in real time and transmitting a depth
signal to the
control system. The
control system is used for receiving and
processing the depth
signal and then appropriately controlling the
actuator to move according to a preset control rule. According to the gas bag type underwater depth-control suspension system, gas is used as buoyancy adjusting media and stored in high-pressure gas cylinders in a compression mode, the gas bag is in a folded state before being inflated, therefore, the suspension system is compact in whole structure, small in size, large in
specific gravity, and capable of loading large weight.
