Abstract

A sandglass type ocean engineering floating structure is provided with an upper structural body shaped as a circular truncated cone or frustum and a lower structural body shaped as a regular circular truncated cone or regular frustum; under a combined state, the smaller bottom surface of the upper structural body is fixedly connected with the smaller bottom surface of the lower structural body to form a junction surface; the axis of the upper structural body and the axis of the lower structural body are positioned on the same straight line; the larger bottom of the upper structural body acts as an upper deck of the floating structure and the larger bottom of the lower structural body acts as a lower plate underwater of the floating structure; the junction surface is a full-load waterplane of the floating structure.

First claim

The invention claimed is:

1. A sandglass type ocean engineering floating structure, comprising:
an upper structural body in shape of a circular truncated cone or frustum; and
a lower structural body in shape of a regular circular truncated cone or regular frustum, wherein the upper structural body and the lower structure body are connected through their respective smaller bases at a junction plane, and an axis of the upper structural body and an axis of the lower structural body are aligned in a same straight line, wherein the upper structural body comprises an upper hull, a center compartment I disposed inside the upper hull that has a same height as that of said upper structural body, and a plurality of watertight compartments disposed between the upper hull and the center compartment I,
wherein the lower structural body comprises a lower hull, a center compartment II that has a same height as that of said lower structural body, and a plurality of watertight compartments disposed between the lower hull and the center compartment II,
wherein a larger base of the upper structural body serves as a deck and a larger base of the lower structural body serves as a bottom of the floating structure, and
wherein the floating structure has a shape of a sandglass and horizontal cross sections of the floating structure are circular or polygonal;
wherein the center compartment I and the center compartment II are connected to form a through hole extending vertically through the floating structure from the larger base of the upper structural body and the larger base of the lower structural body,
wherein the sandglass type ocean engineering floating structure further comprises a plurality of support pillars that are disposed about an exterior surface of the floating structure, wherein an upper end of a support pillar is fixedly attached to the upper structure body at an upper attach point and a lower end of the support pillar is fixedly attached to the lower structural body at a lower attached point, and each individual support pillar and the axis of the floating structure are located in a same plane.

2. The sandglass type ocean engineering floating structure according to claim 1 , further comprising: an annular side plate attached to an outer surface of the lower structural body.

3. The sandglass type ocean engineering floating structure according to claim 1 , wherein all of the plurality of support pillars have a same length, and all upper attach points are located in an upper plane and all lower attach points are located in a lower plane, wherein two adjacent support pillars form two sides in an isosceles triangle.

4. The sandglass type ocean engineering floating structure according to claim 1 , wherein the upper structural body is a circular truncated cone of which a generatrix is a curved line, a folding line, or a combination of curved line and folding line, or a frustum of which a lateral edge is a curved line, a folding lines, or combined curved line and folding line.

5. The sandglass type ocean engineering floating structure according to claim 1 , wherein the lower structural body is defined as a regular circular truncated cone of which a generatrix is a curved line, a folding line, or combination of curved line and folding line, or a regular frustum of which a lateral edge is a curved line, a folding lines, or combined curved line and folding line.

6. The sandglass type ocean engineering floating structure according to claim 1 , wherein the floating structure has a double-hull structure.
