Floating transported and sucking cylindered anchor device and its operating method

Abstract

A sucking drum type ship anchor able to be floating for moving it is a vertical drum with top plate but no bottom plate. A partition is used to divide its internal space into a sealed chamber and an inserted-in-earth chamber. Said sealed chamber has water inlet and outlet tube and air inlet and outlet tube. Said inserted-in-earth chamber has the water and air inlet and outlet tube communicated to its annular tube with the spray holes on lower side. Its sinking and floating methods are also disclosed.

Description

technical field [0001] The invention relates to a floating suction tube mooring ship anchor device and methods for lowering and lifting anchors. Apparatus and methods of operation in the field of shipbuilding, port, coastal and marine engineering. Background technique [0002] During the construction of ports, coasts and ocean engineering projects, some large construction ships, such as crane ships and transport barges, need to be anchored and stationed for work. In some special cases, such as being located in an estuary and in a sea area with high ebb and flow velocity, the anchor device that can provide a large mooring force is required for the construction ship to be stationed. In this case, the anchor device provided by the general ship cannot meet the requirements, and additional mooring anchors need to be provided. The mooring anchors set in the current engineering are usually large-volume concrete blocks buried on the seabed. When this large...

Problems solved by technology

In this case, the anchor device provided by the general ship is difficult to meet the requirements, and it is necessary to set up additional mooring anchors.

The mooring anchors set in the current engineering are usually large-volume concrete blocks buried on the seabed. When this large-volume concrete block is placed, it needs to be transported by barge and installed by lifting ships, and it is difficult to recycle and reuse. Therefore, this large-volume concrete block The comprehensive cost of volumetric concrete blocks used as mooring anchor devices is relatively high

Suction anchor devices are also used to moor ships in engineering, such as gravity type suction anchors (patent No. 98208177.4), double-barrel suction anchors (patent No. 98208178.2), but these traditional suction anchor devices also need to be transported and hoisted by ships. Heavy ships and divers are installed together. Although these suction anchor devices can be recycled and reused, it is inconvenient to install and recover, and the overall cost is also high.
