Embodiment Construction
[0017] The present invention will be described below in conjunction with the accompanying drawings and embodiments. see figure 1 and figure 2 , the present invention is made up of ship berthing member 1, elongated steel plate 2, two support rods 3, inverted "L" shaped connecting plate 4, high pile cap 7, wherein elongated steel plate 2 and two support rods 3 constitute A push-down ice-breaking blade was installed. 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.
[0018] 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 ...

The invention discloses a high pile cap type foundation having the downward pressing type icebreaking performance. The high pile cap type foundation having the downward pressing type icebreaking performance comprises a high pile cap (7) and multiple downward pressing type icebreaking blades arranged on the periphery of the tidal range section of the high pile cap (7). Each downward pressing type icebreaking blade comprises a long-strip-shaped steel plate (1), two supporting rods (3) and a connecting plate provided with a vertical plate, wherein the connecting plate is used for enabling the downward pressing type icebreaking blade to be connected with the high pile cap (7), the two supporting rods (3) are fixed to the vertical plate of the connecting plate (4) in parallel, the supporting rod located on the upper portion is longer than the supporting rod located on the lower portion, the upper supporting rod is arranged at a design high water level, the lower supporting rod is arranged at a design low water level, the long edge of the long-strip-shaped steel plate is fixed to the ends of the two supporting rods (3), and the long-strip-shaped steel plate is inclined relative to the vertical plate. The high pile cap type foundation having the downward pressing type icebreaking performance has a good icebreaking effect.
Description
technical field [0001] The invention relates to a high pile cap type wind power foundation. 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, becau...
