Abstract

The invention discloses a self-adaptable stable control novel draught fan foundation. The self-adaptable stable control novel draught fan foundation comprises an obverse cone foundation, an inverted cone foundation, an EPS (expanded polystyrene) geofoam block body and an active regulation system, wherein the obverse cone foundation is located on the upper portion of the inverted cone foundation, arubber layer is arranged on the exterior of the inverted cone foundation, an obverse cone groove is formed in the bottom of the inverted cone foundation, the EPS geofoam block body is placed in the obverse cone groove, and the active regulation system is placed in the whole foundation. Compared with a traditional gravity type foundation, the self-adaptable stable control novel draught fan foundation keeps bearing and dispersing capability for loads transmitted down from an upper draught fan tower cylinder and an upper engine room, the lower inverted cone foundation and the EPS filling material increase the contact area of the foundation and soil, and further develop bearing capacity of the soil body, the rubber layer can improve rotation of a draught fan, the active regulation system equilibrates the upsetting moment from the upper draught fan tower cylinder and the upper engine room to the top surface of the foundation by controlling distribution of water, and by adopting the structure, the self-adaptable stable control novel draught fan foundation is low in concrete consumption, good in economy, stable in structure, high in reliability and broad in application prospect.

Description

technical field [0001] The invention belongs to the field of new foundation design, installation engineering and wind turbine control system for land wind turbines, and relates to a new wind turbine foundation capable of self-adaptive and stable control. Background technique [0002] The energy consumption and the greenhouse effect in the world today have attracted more and more attention from the world, so the energy industry has begun to develop in the direction of cleanliness and reuse, and wind power generation has emerged as the times require. By 2050, it is estimated that 12% of the world's electric energy will come from wind power generation. At present, the power generation capacity of the world's built wind power plants is 470GW, and 436.7GW of electricity comes from onshore wind farms, accounting for 97% of the total power generation. It can be seen that onshore wind power plays a leading role in wind power generation. Mainland China has a vast land and abundant re...
