Embodiment Construction

[0042] Next, an embodiment of the wind turbine tower and the wind power generator according to the present invention will be described based on the drawings.

[0043] Figure 4 The shown wind power generation device 1 includes: a windmill tower (hereinafter referred to as "tower") 2 erected on a base B; a nacelle 3 arranged at the upper end of the tower 2; A rotor head 4 is rotatably supported and provided at one end of the nacelle 3 .

[0044] A plurality of (for example, three) windmill blades 5 are mounted on the rotor head 4 radially around its rotation axis. In this way, the wind force from the direction of the rotation axis of the rotor head 4 to the windmill blade 5 can be converted into power to rotate the rotor head 4 around the rotation axis.

[0045] An anemometer 7 for measuring a surrounding wind speed value and an anemometer 8 for measuring a wind direction are provided at appropriate places (for example, an upper portion) on the outer peripheral surface of the...

Abstract

The present invention provides a tower for a windmill, and a wind generation device, wherein, a horizontal force received by an upper part of the tower is dispersed to a lower part of the tower or to a base so as to reduce the load acting on a tower shell and suppress deformation of the tower caused by an external force. A monotype-type wind turbine tower (2) in which mainly a tower shell (21) is configured to bear load includes a platform (22) connected to an inner wall of the tower shell (21) and dividing an internal space of the tower in the vertical direction; an elastic bearing (30) of which one end is fixed to the platform (22); and a load transmission member (23) disposed in the internal space of the tower and connecting another end of the elastic bearing (30) to the platform (22) located at a position facing the elastic bearing (30) or to a base (B), so as to transmit a horizontal force from the elastic bearing (30) to the tower shell (21) or the base (B).

Description

technical field [0001] The present invention relates to a monopole windmill tower (pillar) and a wind power generator including the windmill tower. Background technique [0002] A wind power generator is a device in which a rotor head having wind turbine blades is rotated by wind force, and the rotation is increased by a speed increaser or the like to generate electricity by a driven generator. [0003] The rotor head is provided on a windmill tower (hereinafter referred to as "tower"), attached to an end portion of a rotatable nacelle, and supported so as to be rotatable about a substantially horizontal horizontal rotation axis. [0004] Generally, the above-mentioned towers for windmills are often of a steel monopole type using a cylindrical casing. In such a steel monopole tower, since the cylindrical steel casing is the main strength member, increasing the outer diameter of the casing increases the cross-sectional efficiency. Therefore, it is preferable to make the out...
