Basic performance improvement technique of basic ring type wind power tower

Abstract

The invention discloses a basic performance improvement technique of a basic ring type wind power tower, and relates to the technical field of wind power generation. The system comprises a basic ring,an anti-cracking steel cover plate, an annular connecting steel plate, a stud, a rigid connecting piece, high-strength round steel pipe supports and a pre-embedded plate, wherein the basic ring is embedded into foundation concrete, and the upper part of the basic ring is connected with a wind power unit tower; the anti-cracking steel cover plate is arranged in the junction of the basic ring and the top surface of the concrete, and the stud is welded on one surface, which makes contact with the concrete, of the anti-cracking steel cover plate; the annular connecting steel plate and the rigid connecting piece are arranged at an interval according to a certain distance in the height direction of the basic ring; and four to six high-strength round steel pipe supports are annularly arranged atthe bottom of the basic ring, and the lower ends of the high-strength round steel pipe supports are welded with the pre-embedded plate. According to the technique, the common stress performance of the basic ring and the concrete is improved, the prominent problems of connection damage to the basic ring, concrete cracking, a large amount of perforated steel bars, complexity in construction and thelike in a traditional basic form are solved, and the technique has broad engineering application prospects.

Description

technical field [0001] The invention relates to the technical field of wind power generation. Background technique [0002] Wind power is a non-polluting, renewable and clean energy. Onshore wind farms have high power generation, stable wind turbine operation, and mature manufacturing technology, and have been widely used in recent years. [0003] The foundation is located at the bottom of the wind power tower and is used to bear the huge load from the upper part. It is an important part to ensure the safety and normal operation of the wind turbine. Onshore wind turbines usually use reinforced concrete foundations, which are connected to the tower through a foundation ring. This connection method has the advantages of simple structure, fewer procedures, lower cost, and low technical requirements for workers. However, due to poor connection performance between the foundation ring and concrete Strong, under the action of large vertical and horizontal loads on the upper part,...
