Pile group foundation device of offshore wind-driven generator set

Abstract

The invention provides a pile group foundation device of an offshore wind-driven generator set. The pile group foundation device comprises a bearing table, wherein a plurality of support piles are fixedly arranged under the bearing table, the outer sides of the support piles are jointly sheathed with at least one anti-collision ring, and the anti-collision ring is fixedly connected with the support piles. The pile group foundation device of the offshore wind-driven generator set is provided with the anti-collision ring fixedly connected with each support pile, all support piles are connected into a whole through the anti-collision ring, when the anti-collision ring is impacted by a boat, the impact energy of the anti-collision ring is dispersed onto the support piles, and the received impact energy of each support pile is relatively little, so the anti-collision capability of the pile group foundation device is improved, the possibility of bending and damage through collision of the support piles is reduced, and the potential safety hazard caused by the bending and damage through collision of the support piles is reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to pile group foundation devices for offshore wind power generators. Background technique [0002] With the aggravation of the global energy crisis and environmental degradation, clean energy and renewable energy are getting more and more attention from all countries. In recent years, wind power generation has ushered in a period of rapid development in my country, but due to factors such as the reduction of land resources, the lag of power grid construction, and the difficulty of road transportation of large wind power generators, the development of onshore wind power has been restricted to a certain extent. At the same time, the coastal provinces and cities in the east of my country are densely populated, economically developed, and have strong demand for electricity. Every year during the peak period of electricity consumption, there will be power cuts due to power ...

AI Technical Summary

Problems solved by technology

This is because the pile diameter of a single supporting pile (steel pipe pile) of the pile group foundation device is small, and the ability to withstand the impact of the ship is very poor, especially for the foundation of high pile and high cap platform, the pile body of the steel pipe pile is exposed in the water level change area, and each There is no horizontal (horizontal) connecting rod between the supporting piles, which is extremely vulnerable to damage or large deformation caused by the impact of various ships, which will bring great safety hazards to the bearing foundation
