Size adjustable boat anchor used for water surface positioning of stone dumper

Abstract

The invention discloses a size adjustable boat anchor used for water surface positioning of a stone dumper. The size adjustable boat anchor used for water surface positioning of the stone dumper comprises a shackle, an anchor shank, anchor jaws and an anchor crown; the shackle is mounted at the top end of the anchor shank; the bottom of the anchor shank is hinged to the anchor crown; the anchor crown comprises an internal anchor crown and a plurality of layers of external anchor crowns embedded and fixed outside the internal anchor crown; and the anchor jaws comprise internal anchor jaws and aplurality of layers of external anchor jaws, wherein the internal anchor jaws are fixed on the internal anchor crown, and the plurality of layers of external anchor jaws are embedded and fixed outside the internal anchor jaws. According to the size adjustable boat anchor used for water surface positioning of the stone dumper, according to a site actual situation and sailor experience, the numberof the assembled anchor jaws and the assembled anchor crowns are selected to change the model of a boat anchor so as to satisfy a requirement that a located boat is stable in water surface operation;other boat anchors with different types do not need to be carried; and therefore, the application range is wide; and meanwhile, the size adjustable boat anchor used for water surface positioning of the stone dumper has the advantages of simple structural composition, convenient mounting and detaching, high construction efficiency and lower cost.

Description

technical field [0001] The invention relates to the technical field of ship anchors, in particular to a size-adjustable ship anchor used for locating a catapult ship on water. Background technique [0002] As the main part of the anchoring equipment, the anchor is connected to the ship with an iron chain, and the anchor is thrown into the bottom of the water to keep the hull relatively stable on the water. Traditional ship anchors are mainly composed of anchor chains, anchor handles and single anchor claws. During water operations, factors such as the tonnage of the hull, water velocity, water depth, and wind speed can affect the size of the anchor selection. At the same time, it is impossible to Carrying a large number of different types of anchors without matching anchors leads to insufficient stability of the positioning ship. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide an adjustable ...
