Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention has a circular wheel attached to the periphery of a wind turbine, and the circular wheel that rotates together with the wind turbine functions as a flywheel when the wind is light and is equipped when the wind is strong. The present invention relates to a novel wind turbine that controls the rotation of a circular wheel by means of the above-mentioned brake and always keeps normal rotation.

[Conventional technology]

Wind turbines that use natural wind generally have large fluctuations in rotation speed depending on the wind speed, and in power wind turbines other than small household wind turbines, excessive rotation speed during strong winds, such as typhoons, is dangerous because of rotation. You have to control the numbers and keep them safe. Moreover, in a wind turbine for power generation, the number of revolutions must be kept almost constant.

Therefore, a wind turbine generally requires a device for controlling the rotation speed. On the other hand, in the small ones, a device that controls the rotation by tilting the rotating surface of the wind turbine with respect to the wind direction, and in the wind turbine for power generation, a variable pitch mechanism that converts the mounting angle of the propeller blades is often adopted. In large-sized wind turbines, a variable pitch mechanism operated by hydraulic pressure is generally used.

[Problems to be solved by the invention]

Therefore, the present invention performs speed control of a propeller wind turbine by a new mechanism without using a conventional complicated variable pitch mechanism or the like, and accelerates the speed of the propeller during light wind as well as speed control during strong wind such as typhoon. However, the present invention intends to provide a wind power engine having a new mechanism that can always obtain a substantially constant speed.

[Means for solving problems]

In order to achieve the above object, in the wind turbine of the present invention, a circular ring is provided to connect the tips of the propeller wind turbine main blades and fix the same, and a protrusion edge is formed on the outer periphery of the circular ring,
In addition, at the bottom of the circular ring, a plurality of brakes that clamp the circular ring from both sides are installed, and a rotating roller with a groove that fits on the protruding edge of the circular ring is formed on the lower side of the brake. It is a wind turbine with an annulus that is installed in, and that transmits the power transmission shaft from the main shaft of the propeller wind turbine to various underground power machines using various mechanisms.

As a specific large-sized wind-powered prime mover, to the left and right of the power underground transmission shaft installed in the center of the main underframe, a wind turbine prime mover with the above-mentioned basic structure, in which the left and right wind turbine main wings are arranged at opposite pitches, It is a wind power engine in which several units are installed in series and placed on the main underframe, and the entire main underframe is configured to be rotatable.

[Action]

In the wind turbine with a circular wheel of the present invention configured as described above, when the propeller wind turbine main blade rotates due to wind force, the circular wheel attached to the outer periphery of the main blade also rotates, and since there is a considerable mass, the effect as a flywheel In addition, since the circular ring has a circular cross section to reduce the resistance, it is possible to continue the rotation for a long time even under a slight wind. Furthermore, under strong wind, a brake installed under the circular wheel is pressed against the circular wheel from both sides for braking to keep the rotation of the wind turbine within a safe speed. Two or four of these brakes are installed for each wind turbine, and stepwise or full braking can be applied manually or by a power system.

Further, when a danger is predicted due to a typhoon or the like, it is possible to rotate the entire device to the blind spot of the typhoon and apply all braking to fix the device. Note that the lower rotating roller is for contacting with and rotating with the rotation of the circular wheel to ensure stable rotation of the wind turbine. A power motor, gears, and drive wheels are installed at one end of the main underframe, and a large number of wheels installed below the main underframe rotate on a circular rail laid on the base, The 360
Since it rotates by °, it is possible to operate the wind turbine with the main wing rotation axis always aligned with the wind direction during normal operation.

Then, the rotational forces of several wind turbines on the left and right are concentrated on the central drive shaft by the bevel gear transmission device, and a strong rotational motive force can be transmitted to the underground power transmission shaft.
