Embodiment Construction

[0016] The present invention will be described below in conjunction with the accompanying drawings and embodiments. see figure 1 with figure 2 , the present invention is made up of elongated steel plate 2, two support rods 3, and inverted "L"-shaped connecting plate 4, wherein elongated steel plate 2 and two support rods 3 constitute the main body of the push-down ice-breaking blade. The strip-shaped steel plates 2 arranged in a downward pressure manner play a role similar to an inverted cone, guiding the ice sheet to be bent downward to be damaged. The support rod 3 plays a supporting role for the long steel plate 2, and the inverted "L"-shaped connecting plate 4 connects the push-down ice-breaking blade with the high pile cap 7.

[0017] The length L=L of the elongated steel plate 2 1 +L 2 +H / sinα, where L 1 In order to design the distance from the high water level to the top of the elongated steel plate 2, after verification, L 1 Take 1.5 times the maximum ice thickn...

Abstract

The invention discloses a pressing-down type ice breaking blade which comprises a long strip-shaped steel plate (2), two supporting rods (3) and a connection plate with a vertical plate. The connection plate is used for connecting the pressing-down type ice breaking blade with a high-rise pile cap (7), the two supporting rods (3) are fixed to the vertical plate of the connection plate (4) in parallel, the supporting rod located on the upper portion is longer than the supporting rod located on the lower portion, and the long edges of the long strip-shaped steel plate are fixed to the ends of the two supporting rods (3) and form a certain inclination angle relative to the vertical plate. The pressing-down type ice breaking blade has a good ice breaking effect.

Description

technical field [0001] The invention relates to an ice breaking device. Background technique [0002] With the rapid development of offshore wind power generation, high-latitude cold sea areas have attracted more and more attention because of their high wind energy density. In the domestic offshore wind power foundation structure design, the high pile cap structure has mature and complete engineering application experience. In order to facilitate docking of ships and people getting on and off, the high pile cap structure is usually arranged near the waterline. In this way, when the foundation structure of the high-pile cap type wind turbine is applied in the cold sea area, the wide cylindrical structure of the high-pile cap will inevitably suffer from a huge ice load, which will have a negative impact on the design of the foundation structure of the offshore wind turbine and the safe operation of the wind farm. Significant influence. In addition, because the wind power st...
