Power embedment anchor with high-frequency small amplitude vibration

Abstract

The invention relates to a power embedment anchor with high-frequency micro-amplitude vibration in the ship and ocean engineering technical field. The embedment anchor comprises an anchor cover, an anchor shank, an anchor hammer, a lifting lug, a high-frequency micro-amplitude vibration device, a main fin, an anchor chain, a power source and a cable, wherein the anchor cover is arranged on the upper part of the anchor shank; the anchor hammer is arranged on the lower part of the anchor shank; the lifting lug is arranged on the surface of the outer wall of the anchor shank; the anchor chain isconnected with the lifting lug; the high-frequency micro-amplitude vibration device is arranged inside the anchor shank; the main fin consists of two to four sheets which are uniformly and symmetrically arranged on the surface of the outer wall of the anchor shank; the power source supplies power to the high-frequency micro-amplitude vibration device through the cable; and the cable is connected with the power source and the high-frequency micro-amplitude vibration device through an outer cover. The embedment anchor has good holding power and underwater anchor weight ratio under different submarine sediment, can rapidly hold seabed, and is little in windlass tension needed in the process of raising anchors.

Description

technical field [0001] The invention relates to the technical field of ships and marine engineering, in particular to a dynamic embedded anchor with high-frequency micro-amplitude vibration. Background technique [0002] During the construction of inland ports, seaports and oil exploration and development, due to the large sea waves and currents, some offshore and shore equipment, such as ships, mooring drums, floating docks, drilling platforms, etc., need anchoring facilities. Anchoring facilities are mainly composed of anchor body and anchor chain. The anchor body, also known as the anchor, is a structure with sufficient anchoring force buried at a certain depth on the seabed or placed on the seabed; the anchor chain is the link connecting the mooring device and the anchor, and it transmits the mooring force from the sea surface to the An anchor on the seabed. Anchor bodies are divided into gravity anchors and buried anchors. Buried anchors include self sinking anchors,...

Problems solved by technology

Its main disadvantages are: the use of rockets as power for embedding, and the one-time use of the propulsion device, the cost is high; 2) The effect of embedding anchors by rockets decreases significantly with the increase of water depth. When the water depth is large, the rocket thrust requirements are high
