Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0032] 1. New lightweight power anchor

[0033] figure 1 -4 is a schematic diagram of the new lightweight dynamic installation anchor 1, the new lightweight dynamic installation anchor 1 is mainly composed of a wing plate 11, an anchor handle 12 and a connecting rod 14. The wing plate 11 is composed of two triangular flat plates symmetrically spliced ​​together, and the dimensions of the two right-angled sides of the triangular flat plate can be adjusted according to actual conditions to adapt to different soil strengths and soil properties. Two triangular flat plates can be connected by welding, riveting, hinged and other processing techniques to form the wing plate 11 . The angle between the two triangular flat plates is greater than 180°, which is to balance the eccentricity caused by the anchor handle...

Abstract

The invention belongs to the technical field of oceanographic engineering, and relates to a novel light power installing anchor and an installing method. The novel light power installing anchor is mainly composed of a wing plate, an anchor bar and a connecting rod. The wing plate is formed by symmetrically splicing two triangular flat plates. The connecting rod is installed at the tail portion ofthe wing plate. The anchor bar is of an inverted V type structure composed of two trapezoid flat plates and is symmetrically fixed to the wing plate. A propeller can be fixed at the tail portion of the novel light power installing anchor through a shear pin, and the novel light power installing anchor, the propeller and the shear pin are combined to form a combined anchor; the combined anchor is put in seawater, an installing anchor chain is released, and the combined anchor penetrates into soil; the installing anchor chain is tensioned, the shear pin is cut off, the propeller is pulled out, and the novel light power installing anchor is left in soil; a working anchor chain is tensioned, and the angle of the novel light power installing anchor is adjusted; the propeller is used for installing a next novel light power installing anchor after being taken out. The novel light power installing anchor has the advantages of being light in weight and high in bearing efficiency, improving thesinking and penetrating depth in soil and reducing cost.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and relates to a novel light-weight dynamic installation anchor and an installation method. Background technique [0002] With the rapid development of social economy and the gradual depletion of land and shallow sea oil and gas resources, people gradually shift the development of oil and gas resources to deep sea. In the deep-sea environment with a water depth of more than 300-500m, oil and gas exploration, acquisition and storage equipment are mainly connected to the anchorage foundation acting on the seabed surface or embedded in the seabed through the anchor chain system. Therefore, the anchor foundation is the root of the mooring system and the prerequisite for the safe operation of the superstructure. Anchoring foundations suitable for deep-sea mooring systems mainly include suction caissons, dragging anchors, suction mounting plate anchors and dynamic mounting anchors. Suction...
