Problems solved by technology

[0003] However, under the combined action of wind, waves and currents, the existing wind power foundations are very easy to move the sediment near the piles, exposing the foundation structure, resulting in a decrease in the overall natural vibration frequency and more prone to fatigue damage. In addition, the existing anti-corrosion The installation of the scouring device is relatively inconvenient, and it is usually necessary to manually dive into the seabed to anchor the bionic grass to the seabed. Therefore, the installation cost of the bionic grass is high

Embodiment 1

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0032] Such as Figure 1 to Figure 9 As shown, a conveniently installed offshore wind power anti-scouring equipment includes a wind power foundation 1, and a bionic grass support assembly 2 is slidably arranged on the wind power foundation 1. The bionic grass support assembly 2 includes a bionic grass installation frame 21, and the bionic grass installation frame 21 along There are at least four arrays in the circumferential direction of the wind power foundation 1. The bionic grass installation frame 21 is provided with a bionic...

Embodiment 2

[0042] like Figure 9 As shown, the parts that are the same as or corresponding to those in Embodiment 1 adopt the reference numerals corresponding to Embodiment 1. For the sake of simplicity, only the differences between Embodiment 1 and Embodiment 1 are described below; the differences between Embodiment 2 and Embodiment 1 The difference lies in that several energy-dissipating holes 91 are arrayed on the outer sides of the bionic grass mounting frame 21 and the bottom plate 12 along the circumferential direction.

[0043] Here, in this embodiment, several energy-dissipating holes 91 are arrayed along the circumferential direction outside the bionic grass mounting frame 21 and the bottom plate, effectively reducing the flow velocity of the bottom undercurrent when the bionic grass mounting frame 21 descends to the bottom, and When the sea current impacts, it can achieve the effect of energy dissipation and shock absorption.

Abstract

The offshore wind power anti-scour equipment convenient to install comprises a wind power foundation, a bionic grass supporting assembly is arranged on the wind power foundation in a sliding mode, the bionic grass supporting assembly comprises bionic grass installation frames, and the at least four bionic grass installation frames are arranged in the circumferential direction of the wind power foundation in an array mode; a bionic grass unfolding mechanism is arranged on the bionic grass mounting frame, the bionic grass unfolding mechanism comprises an inflation assembly, and a buoyancy ball is used for supporting when the bionic grass supporting assembly is mounted; the bionic grass supporting assembly is used for driving the bionic grass to descend together after the buoyancy ball is separated and unfolding the bionic grass in a manner of inflating the interior of the bionic grass under the cooperation of the unlocking piece and the inflating assembly in the descending process, so that the bionic grass is automatically mounted; the installation mode is simple, the installation efficiency is high, the installation firmness is high, and meanwhile the installation cost is low.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to a conveniently installed anti-scouring equipment for offshore wind power. Background technique [0002] Wind power is the fastest growing green energy technology in the world. While the construction of onshore wind farms is developing rapidly, people have noticed some restrictions on the utilization of onshore wind energy, such as large land occupation and noise pollution. Due to the abundant wind energy resources in the sea and the feasibility of today's technology, the sea will become a rapidly developing wind power market, but accidents of offshore wind turbines also occur frequently, and most of the accidents of offshore wind turbines are caused by unstable pile foundations Therefore, it is very necessary to take corresponding anti-scouring measures. [0003] However, under the combined action of wind, waves and currents, the existing wind power foundations are v...
