Inflatable draining floating dock

Abstract

The invention provides an inflatable drainage type floating dock, which includes a buoyant tank, a dock wall and lifting equipment, the dock wall is arranged on both sides of the upper surface of the buoyant tank, several independent cabins are arranged in the buoyant tank, and the bottom of the buoyant tank is provided with The bottom plate and the cabin include a fully-sealed cabin and an inflatable drainage cabin. The bottom plate is provided with openings communicating with the inflatable drainage cabin; a compressed air drainage system is also provided, and the compressed air drainage system includes air pipelines and control systems; The air compressor, compressed air main pipe, compressed air branch pipe and cabin compressed air pipeline connected by road, the cabin compressed air pipeline is arranged in the described inflatable drainage cabin; the control system includes a pressure gauge arranged in the air pipeline , a flow meter, a flow limiting valve, and a controller, the output ends of the pressure gauge and the flow meter are connected to the controller, and the output ends of the controller are connected to the flow limiting valve. The invention has the advantages of simple structure, convenient construction, low cost and fast sinking / floating speed.

Description

technical field [0001] The invention relates to the field of floating docks, in particular to an inflatable drainage type floating dock. Background technique [0002] Floating dock is an inland and offshore mobile ship repair platform, which has the advantages of less investment and flexible movement, and is one of the key facilities in the ship repair / shipbuilding industry. At present, the sinking and floating of the floating dock are controlled by ballast water, and the sinking or floating of the floating dock is realized by injecting or discharging ballast water into the ballast water tank. However, this kind of ballast water type floating dock has some disadvantages: (1) There are many ballast pipelines, and the pipes are large in diameter and heavy in weight; (2) The construction is difficult and the construction cost is high; It takes a long time to sink and float; (4) The energy consumption of drainage is large, and the operating cost is high. In particular, the sin...

Problems solved by technology

However, this kind of ballast water type floating dock has some disadvantages: (1) There are many ballast pipelines, and the pipes are large in diameter and heavy in weight; (2) The construction is difficult and the construction cost is high; Sinking and floating time is long; (4) Drainage consumes a lot of energy and high operating costs

In particular, the sinking and floating time is too long, which takes up more effective dock repair time, and the floating dock has not been fully utilized
