Description

Technical Field

[0001] The utility model relates to the technical field of offshore photovoltaics, and in particular to an offshore photovoltaic ice-breaking device and system. Background Art

[0002] The statements in this section merely provide background technology related to the present invention and do not necessarily constitute prior art.

[0003] The currently used offshore photovoltaic pile foundations are PHC pipe piles or small steel pipe piles, which have low strength and weak rigidity and are difficult to withstand ice loads such as extreme drift ice.

[0004] The inventors found that most existing solutions use icebreakers to break ice, which takes a long time, has low efficiency and high cost. In addition, there are few icebreakers, which makes it difficult to meet the icebreaking and operation and maintenance needs of large-scale photovoltaic fields in extremely cold weather. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the utility model provides an offshore photovoltaic icebreaking device and system, which can ensure the safety of the photovoltaic area without the need for operation and maintenance work such as icebreakers, has high icebreaking efficiency and low cost.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In a first aspect, the utility model provides an offshore photovoltaic icebreaking device.

[0008] An offshore photovoltaic ice-breaking device comprises: a lower bottom plate and a plurality of upper ice-breaking edges, wherein the upper ice-breaking edges are fixedly connected to the upper surface of the lower bottom plate, and the corners of the upper ice-breaking edges are covered with steel plates.

[0009] As a further limitation of the first aspect of the utility model, the upper ice-breaking edge is connected to the lower base plate through a steel mesh.

[0010] As a further limitation of the first aspect of the utility model, the upper ice-breaking edge and the lower base plate are cast as a whole.

[0011] As a further limitation of the first aspect of the utility model, diamond-shaped anti-slip patterns are arranged on the lower bottom plate.

[0012] As a further limitation of the first aspect of the present invention, the lower base plate is a reinforced concrete base plate.

[0013] As a further limitation of the first aspect of the present utility model, the lower base plate is a rectangular base plate.

[0014] As a further limitation of the first aspect of the utility model, a plurality of upper ice-breaking ridges are arranged at equal intervals, the upper ice-breaking ridges are wider at the bottom and narrower at the top, and the front ends of the upper ice-breaking ridges are inclined facing the ice surface.

[0015] As a further limitation of the first aspect of the utility model, the upper ice-breaking edge is a reinforced concrete structure.

[0016] As a further limitation of the first aspect of the present utility model, the lower front end of the upper ice-breaking edge is triangular, and the upper front end of the upper ice-breaking edge is an arc slope or a horizontal slope.

[0017] In a second aspect, the utility model provides an offshore photovoltaic icebreaking system.

[0018] An offshore photovoltaic icebreaking system comprises the offshore photovoltaic icebreaking device described in the first aspect of the utility model, wherein a plurality of offshore photovoltaic icebreaking devices are arranged around the outer side of a photovoltaic field.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. When drifting ice flows toward the ice-breaking device of the utility model under the action of tides, it will be cut and broken by the sharp blades of the ice-breaking edges under the action of the extrusion force; the drifting ice that has not been broken by the sharp blades will be bent and broken upward along the ice-facing slope of the upper ice-breaking edges under the extrusion of the subsequent ice row; the remaining unbroken ice blocks will be bent and broken between the upper ice-breaking edges; due to the resistance of the ice-breaking device in front, the small ice blocks broken by the ice-breaking device are not squeezed forward by the ice row, and no longer pose a threat to the photovoltaic field.

[0021] 2. This icebreaker uses the ice itself to passively break ice. Unlike icebreakers, it does not consume external energy such as diesel and electricity, and requires very little subsequent operation and maintenance. The structure itself is a reinforced concrete structure with a very low project cost. The spacing between the upper icebreaker ridges is large, which is conducive to water exchange. It is a permeable structure with little impact on the marine environment.

[0022] Advantages of additional aspects of the present invention will be partially given in the following description, and partially become apparent from the following description, or be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
