Problems solved by technology

[0003] On the one hand, the winches that drive the bridge up and down consume a lot of energy. On the other hand, the consumption of compressed air for the watertightness of the underwater motor room is also very large. The long-term operation of the cutter suction dredger not only consumes and wastes A large amount of energy, while causing damage to the winch system, increasing the unsafe factor

Abstract

The invention discloses a bridge air adjusting device. The device comprises a bridge, a first adjusting cabin, a second adjusting cabin and a pipeline, one end of the bridge is a rotating end, the other end of the bridge is a swinging end, the first adjusting cabin is arranged on the swinging end, the first adjusting cabin is provided with a first cavity, the second adjusting cabin is located on one side, close to the rotating end, of the first adjusting cabin, the second adjusting cabin is provided with a second cavity, the first adjusting cabin is provided with a through hole, the pipeline communicates the first cavity and the second cavity, when the bridge is descended, seawater flows into the first adjusting cabin through the through hole, internal air is pressed into the second cavitythrough the pipeline, and obstruction of air buoyancy is reduced; and when the bridge is lifted, compressed air in the second cavity in the second adjusting cabin is released into the first cavity soas to form auxiliary upward buoyancy force for lifting of the bridge, and the traction load of a bridge motor is reduced. In addition, the invention further discloses a bridge air adjusting control method.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a bridge air conditioning device and a control method. Background technique [0002] On the traditional cutter suction dredger, due to the relatively large size, weight and inertia of the cutter bridge, when the bridge is lifted and lowered or when the cutter suction dredger performs dredging operations, the traditional cutter suction dredger The reamer bridge is operated mainly by the pulling force of the bridge lifting winch, and the driving motor of the reamer and the submerged pump is located in an underwater closed compartment, which needs to be protected by watertight protection. [0003] On the one hand, the winches that drive the bridge up and down consume a lot of energy. On the other hand, the consumption of compressed air for the watertightness of the underwater motor room is also very large. The accumulated long-term operation of the cutter suction dredger not only cons...
