Separable self-drilling embedment anchor

Abstract

A separable self-drilling embedment anchor belongs to the technical field of water conservancy and ship ocean engineering, and comprises an anchor body with an internal hollow cavity, a propeller and a separating component, wherein the propeller is used for providing power to lead the anchor body to be automatically drilled into and embedded into the soil, and the separating component arranged on the propeller is used for connection and disconnection of the propeller with the anchor body. Connection and disconnection of the anchor body with the propeller are completed by the separating component. The anchor body can be embedded into the soil under the action of exciting force of the propeller and gravity, and when the anchor body is embedded with a certain depth, a catapult is started to generate jet impact to push the propeller out of the anchor body, the anchor body is embedded into a deeper position of a bed material, peripheral liquefied bed materials backfill the hollow cavity of the anchor body to enhance the anchoring force, and embedment of the anchor body and recovery of the propeller are finally completed. Therefore, the embedment depth and the anchoring force of the dynamic anchor are increased, operating efficiency is improved, and technological implementation is simple. The separable self-drilling embedment anchor is low in construction cost as the propeller can be recovered and reused, and is low in manufacture cost as the hollow cavity designed in the anchor body can be used for backfilling the bed materials.

Description

technical field [0001] The invention relates to an anchoring equipment and technology in the technical field of water conservancy and marine engineering, in particular to a new type of separated self-drilling embedded anchor. Background technique [0002] Mooring systems are crucial to the safety and stability of moored objects. In addition to ships, marine structures such as drilling platforms, buoys, underwater monitoring systems, deep-water aquaculture cages, etc., the reliability of the mooring system of these moored objects is the key to ensuring their normal and safe operation at designated locations. Traditional anchors such as high holding power anchors rely on the anchor chain and the weight of the anchor to provide resilience and limit the movement of the moored object. However, if the anchor chain is not long enough and the anchor does not have enough weight when encountering strong winds or waves, resulting in insufficient anchoring force, anchor walking will oc...

AI Technical Summary

Problems solved by technology

Its main disadvantages are: 1) The effect of rocket embedding anchors decreases significantly with the increase of water depth. When the water depth is large, the rocket thrust is required to be high.

2) After the gunpowder is burned, the anchor body forms a cavity, which reduces the weight, and the bed sand cannot be backfilled, so the anchor body cannot provide sufficient anchoring force

Its main disadvantage is that for permanent mooring systems, when the anchor is installed, the motor has to stay in the anchor body, which is expensive
