Problems solved by technology

[0003] The multi-section towers of the fan usually need to be connected by flanges. The common method in the prior art is to install flanges at the ends of the adjacent towers, and then pass the flanges at the two ends through the fixing parts. However, in practical applications, the place where the fan is installed usually has a strong wind force, and the flange connection cannot obtain strong bending resistance through the above-mentioned simple connection, and it is very likely to break under the action of strong wind, and even cause a safety accident

Abstract

The invention relates to the technical field of wind power generation, in particular to a fan tower tube connecting structure and a construction method thereof. The fan tower tube connecting structurecomprises an upper tower tube, a lower tower tube connected with the upper tower tube, and a clamping device; an upper flange is arranged at the junction of the upper tower tube and the lower tower tube, and the lower tower tube is provided with a lower flange connected with the upper flange at the junction; the clamping device can tighten the upper flange and the lower flange together; and the upper flange and / or the lower flange is provided with a first magnetic attraction part, and the clamping device is provided with a second magnetic attraction part connected with the first magnetic attraction part. Through arrangement of the clamping device, the technical problem that the strength of the junction of the upper fan tower tube and the lower fan tower tube is insufficient is solved, andthe strength of the junction is improved; and through cooperative arrangement of the first magnetic attraction part and the second magnetic attraction part, the technical problems that the strength of the junction of the upper fan tower tube and the lower fan tower tube is insufficient and the clamping device is not prone to being aligned at the upper flange and the lower flange during mounting are further effectively solved, and the strength of the junction is effectively improved.

Description

Technical field: [0001] The invention relates to the technical field of wind power generation, in particular to a fan tower connection structure and a construction method. Background technique: [0002] Wind generators, referred to as fans, are power equipment that convert wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Fans are installed on land and at sea; the main support structure of the fan is the tower, and the tower of the fan The tube is usually divided into multiple sections, which need to be connected, including the connection between the tower tube and the foundation, and between the sections of the tower tube. [0003] The multi-section towers of the fan usually need to be connected by flanges. The common method in the prior art is to install flanges at the ends of the adjacent towers, and then pass the flanges at the two ends through the fixing parts. However, in practical applications, the place wher...
