Description

[Detailed Description of the Invention] [Field of Industrial Application] The second invention is that a circular ring is attached to the periphery of a windmill, and the circular ring that rotates together with the windmill acts as a flywheel when there is a light wind and acts as a flywheel when there is a strong wind. This invention relates to a new wind power motor that uses an equipped brake to control the rotation of a circular ring to maintain normal rotation at all times.

[Conventional technology]

Wind turbines that use natural wind generally have a rotation speed that fluctuates greatly depending on the wind speed, and for power wind turbines other than small wind turbines for home use, if the rotation speed becomes too high during strong winds such as a typhoon, it can be dangerous due to the strength. We must control the numbers and maintain safety. In addition, wind turbines for power generation must maintain a nearly constant rotational speed.

For this reason, wind turbines generally require a device to control the rotation speed. On the other hand, small-sized wind turbines often use devices that control rotation by tilting the rotating surface of the wind turbine with respect to the wind direction, and variable pitch mechanisms that change the installation angle of the propeller blades are often used for power generation wind turbines. Large-scale wind turbines for power generation generally use variable pitch mechanisms operated by hydraulic pressure.

[Problem that the invention seeks to solve]

Therefore, this invention uses a new mechanism to control the speed of a propeller wind turbine without using the conventional complicated variable pitch mechanism.It not only controls the speed in strong winds such as typhoons, but also accelerates the speed of the propeller in light winds. However, the present invention aims to provide a wind motor with a new mechanism that can obtain a nearly constant speed at all times.

c Means for Solving the Problem] In order to achieve the above object, in the wind power generator of the present invention, a circular ring is provided that connects and fixes the tips of the propeller wind turbine main blades, and a ring is provided on the outer periphery of this circular ring. A protruding edge is formed, and a plurality of brakes are installed at the bottom of the ring to hold the ring from both sides, and a groove on the outer periphery is provided below this to fit into the protruding edge of the ring. This is a circular wind power generator in which the formed rotating roller is rotatably constructed, and furthermore, the power transmission shaft is transmitted from the main shaft of the propeller windmill to various underground power machines using various mechanisms.

In addition, as a specific large-scale wind turbine, there are several wind turbines with circular wheels of the above basic structure, in which the left and right wind turbine main blades are configured with opposite pitches on the left and right of the underground power transmission shaft installed in the center of the main underframe. This is a wind power motor in which the two main underframes are installed in series and mounted on a main underframe, and the entire main underframe is configured to be freely rotatable.

[Effect]

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

Additionally, if danger is predicted during a typhoon, the entire device can be rotated into the typhoon's blind spot, and then fully braked and immobilized. Note that the lower rotating roller rotates in contact with the circular ring as it rotates, and is used to ensure stable rotation of the wind turbine. In addition, a power motor, gears, and drive wheels are installed at one end of the main frame, and a large number of wheels placed on the underside of the main frame,
It rotates on a circular track laid on the base, and the main underframe rotates 360°.
Because it rotates, during normal operation, it is possible to operate the windmill with the main blade rotation axis always aligned with the wind direction.The rotational power of the several windmills on the left and right is concentrated on the central drive shaft by the bevel gear transmission device, Powerful rotational motive power can be transmitted to the underground power transmission shaft [Example] The following example will be explained with reference to the drawings. In Figures 1 and 2, the tip of the propeller wind turbine main blade (1) is A circular ring (2) is provided which is connected and fixed to this, and the circular ring (2)
A protruding edge (3) is formed on the outer periphery of the ring, and two sets of brakes (4) are installed at the bottom of the ring to hold the ring (2) from both sides. A rotary roller (5) having a groove (6) formed on its outer periphery to fit into a protruding edge (3) is rotatably constructed, and a power transmission shaft (8) is connected to the main shaft (7) of the propeller wind turbine (1). This is a wind motor that transmits power to various underground power machines using a set of gear mechanisms (9).

Next, the wind motor shown in Fig. 3 is an example of a powerful wind motor using four of the above-mentioned circular wind motors.
As shown in the figure, there are two circular wind turbines (A) each with the main blades of the left and right propeller wind turbines configured at opposite pitches, on both the left and right sides of the underground transmission shaft using the bevel gear surface installed in the center of the turbine. The main underframe (balanced on the IO and an appropriate number of wheels with rims 04 at the bottom of the main underframe θO) is installed in series and rotatably attached, and these are installed in a circular shape on the base. This is a wind power motor in which the entire main underframe (10) is configured to be freely rotatable with respect to the wind direction by a power motor 06) placed on a rail αω and installed at one end of the main underframe (11). In this case, the brake (4) does not need to be attached to each wind turbine.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

4゜The circular ring attached to the outer periphery of the main wing has a circular cross section, has little wind resistance, and has considerable mass, so it acts as a flywheel in light winds and keeps the windmill rotating for a long time. can do. In addition, in strong winds, the brake elements (hard synthetic rubber) of the equipped brake are pressed against both sides of the circular ring by power to apply braking and maintain the rotation of the wind turbine within a safe speed. In addition, the new mechanism allows the main underframe to rotate along the wind direction during normal times, and during a typhoon to rotate at right angles to the wind direction, applying full braking to the wind turbine and main underframe to maintain safety. It is a wind powered engine.
