Problems solved by technology

During the interaction between the sea ice and the cone structure, although the horizontal force is reduced due to the slope form, it is also possible that the sea ice climbs and accumulates along the cone slope
The accumulation of sea ice will increase the horizontal and vertical force of sea ice on the conical structure, thus threatening the safety of the offshore platform structure

Embodiment 1

[0025] The invention provides an icebreaking pyramid, such as figure 1 , figure 2 , image 3 As shown, the ice-breaking pyramid is constructed in the form of a convex body. Further, the ice-breaking pyramid is a multi-edge structure. Further, the ice-breaking pyramid provided in this embodiment is a quadrangular pyramid Specifically, the quadrangular pyramid structure can be functionally divided into an upper triangular pyramid and a lower triangular pyramid.

[0026] In the process of sea ice climbing up the slope, the lower triangular pyramid plays the role of breaking the ice and making the crushed ice turn over and fall. At the same time, the two sides of the lower triangular pyramid can displace the sea ice to the two sides, so that the sea ice slides down along the two sides of the pyramid structure, thereby inhibiting the accumulation of sea ice. The upper triangular pyramid is mainly used to support the lower triangular pyramid, and at the same time, it can also ma...

Embodiment 2

[0028] As above-mentioned ice-breaking pyramid, the difference of this embodiment is that, as figure 1 As shown, the quadrangular pyramid includes a first long diagonal part XE, a second long diagonal part XF, a first short diagonal part XG, and a second short diagonal part XH extending from the intersection X to four directions;

[0029] The length of the first long diagonal part XE is c, the length of the second long diagonal part XF is b, the length of the first short diagonal part XG and the second short diagonal part XH are both d; wherein, b, c, d are greater than 0.

[0030] Preferably, the first long diagonal part XE and the second long diagonal part XF extend from the intersection point X to both sides along the same axis; the first short diagonal part XG and the second long diagonal part The two short diagonals XH extend from the intersection point X to both sides along different axes, that is, the first short diagonal XG and the second short diagonal XH form an ang...

Embodiment 3

[0042] As the above-mentioned ice-breaking pyramid, the difference of this embodiment is that the triangular pyramid surrounded by the intersection points X, Y, G, H, and E on the quadrangular pyramid is an upper triangular pyramid, so The triangular pyramid surrounded by the meeting points X, Y, G, H and F on the quadrangular pyramid is the lower triangular pyramid.

[0043] In the process of sea ice climbing up the slope, the lower triangular pyramid plays the role of breaking the ice and making the crushed ice turn over and fall. At the same time, the two sides of the lower triangular pyramid can displace the sea ice to the two sides, so that the sea ice slides down along the two sides of the pyramid structure, thereby inhibiting the accumulation of sea ice. The upper triangular pyramid is mainly used to support the lower triangular pyramid, and at the same time, it can also make the sea ice fall along the two sides, preventing sea ice from accumulating on the top of the lo...

Abstract

The invention provides an ice breaking pyramid. The ice breaking pyramid is a rectangular pyramid structure; the rectangular pyramid is divided into an upper triangular pyramid and a lower triangular pyramid; and the rectangular pyramid comprises a first long diagonal part XE, a second long diagonal part XF, a first short diagonal part XG and a second short diagonal part XH for extending in four directions from an intersecting point. In the process of sea ice upwards climbing along slopes, the lower triangular pyramid achieves the effects of ice breakage and overturning fall of broken ice; at the same time, two side surfaces of the lower triangular pyramid can push the sea ice to two sides, so that the sea ice slides on two sides of the pyramid structure to achieve the effect of inhibiting accumulation of the sea ice; and the upper triangular pyramid mainly achieves the effect of supporting the lower triangular pyramid, and meanwhile, can enable the sea ice to fall along two side edges to prevent accumulation of the sea ice at the top of the lower triangular pyramid.

Description

technical field [0001] The invention relates to the field of ice-breaking structures, in particular to a movable ice-breaking device. Background technique [0002] In oceans in cold regions, the surface of the sea water freezes over in winter. Under the action of wind, current and other environmental driving forces, sea ice will drift on the sea surface. When the drifting sea ice acts on the ocean engineering cone structure, it will interact with the ocean engineering cone structure. Since the ice load caused by bending failure of the ice sheet is lower than the ice load caused by crushing failure under the same conditions, conical structures or slope structures are often used at the waterline of ice-covered ocean structures to reduce the impact of sea ice on structures. force. There are a considerable number of conical structures that play a role in various marine engineering structures, including a series of jacket platforms in the heavy ice area of ​​the Bohai Sea in my...
