Ocean current vibration reduction device of ocean wind power pile

Abstract

The invention discloses an ocean current vibration reduction device of an ocean wind power pile, and belongs to the field of offshore wind power equipment. The ocean current vibration reduction deviceis designed to reduce vibration of the wind power pile in ocean currents and improve the stability of the wind power pile. The ocean current vibration reduction device is composed of annular fixed components, vibration reduction blade components and supporting rods. Each annular fixed component is formed by connecting two semicircular steel sheets, and screws capable of being screwed inwards arearranged at the two ends. Each vibration reduction blade component comprises large vibration reduction blades, small vibration reduction blades, bearings and a fixed ring, wherein every two small vibration reduction blades are connected with the corresponding large vibration reduction blade through the corresponding bearings, and each large vibration reduction blade is connected with the fixed ring through the corresponding bearing. The supporting rods are arranged in bilateral symmetry, and the annular fixed components and the fixed rings are evenly welded to the supporting rods at intervals.The ocean current vibration reduction device is simple in structure and high in engineering practicality, the vibration action of the wind power pile under the ocean current action can be effectivelyreduced, the stability of the wind power pile is greatly improved, the service life of the wind power pile is greatly prolonged, and the technology is economically feasible.

Description

technical field [0001] The invention belongs to the field of offshore wind power equipment, and in particular relates to a vibration damping device, in particular to an ocean current vibration damping device for an ocean wind power pile. Background technique [0002] Due to the abundant offshore wind resources, little impact on people's production and life, and favorable conditions such as not occupying cultivated land, offshore wind power generation has received more and more attention in recent years. At present, the single pile technology is the most widely used in the wind turbine support technology of offshore power generation. The advantage of the wind power single pile is that it does not need to arrange the seabed, and the pile body is directly placed under the seabed, and the construction method is simple. [0003] However, due to the continuous erosion of the pile body by the ocean current, the wind power pile will vibrate, which will greatly reduce the stability o...

Problems solved by technology

[0003] However, due to the continuous erosion of the pile body by the ocean current, the wind power pile will vibrate, which will greatly reduce the stability of the pile itself and the bearing capacity of the pile foundation, shorten the service life of the wind power pile, and the maintenance and replacement of the offshore wind power pile is technically complicated and consumes a lot of energy. It is time-consuming and laborious, causing great economic losses. However, there is no device to reduce the vibration of offshore wind power piles in the current wind power vibration reduction equipment.
