Novel wind power tower tube and wind power unit comprising tower tube

Abstract

The invention discloses a novel wind power tower tube and a wind power unit comprising the tower tube. The novel wind power tower tube comprises a tube body; the tube body is divided into a pluralityof sections; all the tube body sections are coaxially mounted through a centering component; rib plates are uniformly distributed on the inner wall of the tube body in a surrounding mode in the extending direction of the tube body; and the outer wall of the tube body is coated with a composite layer for reducing vibration of the tube body. The problems that according to traditional technologies, due to vibration of the tower tube caused by blades, the tower tube diameter and the tower tube wall thickness are increased so that the strength requirements of the wind power unit can be met, the coaxiality of the multiple tower tube sections cannot be ensured in the installation process, and accidents are liable to occur to a lifting platform are solved.

Description

technical field [0001] The invention relates to a novel wind power tower and a wind turbine including the tower, and belongs to the technical field of auxiliary equipment for wind generators. Background technique [0002] Wind power generation is the fastest growing new energy industry in the world today. The wind turbine tower is the load-bearing component of the wind turbine. It supports the impeller to a certain height to obtain a sufficient wind speed to drive the impeller to rotate and convert wind energy into electrical energy. . In order to develop wind resources with relatively low wind speed and pursue more power generation, wind turbines are developing towards the trend of large blades and tall towers; [0003] In the existing technology, a lot of research and practice have been done on the above problems of the tower tube; for example, the patentee Beijing Wanyuan Industrial Co., Ltd. applied for an invention with the application number CN201721414629.6 on Octobe...

AI Technical Summary

Problems solved by technology

[0011] The technical problem to be solved by the present invention is to provide a new type of wind power tower and a wind turbine including the tower to solve the vibration caused by the blades to the tower in the traditional technology; by increasing the diameter of the tower and The wall thickness of the tower is to meet the strength requirements of the wind turbine; the coaxiality between the multi-section towers cannot be guaranteed during the installation process; the lifting platform is prone to safety accidents
