And is provided. FIG. 11 is an explanatory view schematically showing the force that the wind turbine blade receives from the airflow. In FIG. 11, reference numeral 6 indicates a virtual straight line connecting the blade leading edge 4 and the blade trailing edge 5. Is called chord. Reference numeral 7 indicates a chord 6
And an airflow direction, and this angle is called an angle of attack. The airflow flows from the upstream side of the blade front wing 4 to the downstream side of the blade trailing edge 5, and the passage of the airflow generates a pressure distribution on the blade surface and a frictional force between the airflow and the blade surface. As a sum of these forces, the wing receives a lift 8 acting in a direction perpendicular to the airflow and a drag 9 acting in the direction of the airflow. In general, the windmill blades can extract the wind energy more effectively as the wing rotation force as the lift is larger and the drag is smaller.
The amount of power generation also increases.

縁の汚れは翼面の平滑性を損なうため、より下流側の翼
面近傍流れを乱れの小さい層流状態から乱れの強い乱流
状態に遷移させやすくする。By the way, since the windmill is installed outdoors, bird feces and insects flying on the wind collide with the windmill blades during long-time use, and the vicinity of the leading edge becomes dirty. Since dirt on the leading edge impairs the smoothness of the blade surface, the flow near the blade surface on the downstream side is more likely to be changed from a laminar flow state with small turbulence to a turbulent state with strong turbulence.

る。FIG. 12 shows a representative example of the relationship between the drag received by the airfoil from the airflow and the angle of attack. In FIG. 12, the dashed line shows the case where the blade leading edge is smooth and the blade surface flow is laminar, and the solid line shows the case where the blade leading edge is provided with roughness and the blade surface flow transitions to turbulent flow. In each case, the airflow velocity is constant.

不具合がある。As shown in FIG. 12, when the wing surface flow transitions to a turbulent state due to the roughness provided near the leading edge of the wing, the friction between the air flow and the wing surface increases, and the drag received by the wing from the air flow hardly increases. At the angle of attack. As described above, in the conventional wind turbine blade, there is a problem that the drag received by the wind turbine blade from the airflow increases due to the contamination of the leading edge due to long-time use, and the performance is deteriorated.

And cleans the leading edge of the wing while spilling.This removes dirt such as insects attached to the outer surface of the leading edge of the wing and keeps the smooth wing surface. Will be fully maintained. (2) When the cleaning liquid supply pipe inside the wind turbine blade is connected to the cleaning liquid tank inside the nacelle, the cleaning liquid is supplied from the tank at any time, and the cleaning liquid can be ejected from the slit at the front edge of the wind turbine blade. Therefore, the outer surface of the leading edge of the wind turbine blade is always kept clean and smooth, so that the separation of the flow of the wind along the leading edge of the wind turbine blade can be prevented, whereby the performance of the wind turbine can be sufficiently maintained. . (3) If a water intake tray for receiving rainwater is provided and rainwater can be automatically supplied from the water intake tray to the cleaning liquid tank as a cleaning liquid, the cleaning liquid can be appropriately supplied to the cleaning liquid tank inside the nacelle. This is advantageous in that the maintenance is greatly simplified. (4) When a heating wire is buried along the leading edge of the wind turbine blade and power generated by the wind power generator is supplied to the heating wire, when insects collide with and adhere to the leading edge of the blade, It can be automatically incinerated at the leading edge of the blade, which is heated by the heating wire, and the ash generated by this incineration is blown off by wind. In this case, too, the leading edge of the windmill blade is kept clean and smooth. , The performance of the windmill can be maintained. (5) If a brush that can move along the leading edge of the wind turbine blade is provided, the brush will clean the leading edge of the blade at any time.
Also in this case, the performance of the windmill can be sufficiently maintained. (6) When the brush drive mechanism is provided inside the wind turbine blade, the mechanism is not exposed to the outside and does not cause an increase in air resistance, and the performance deterioration of the wind turbine blade is sufficiently avoided. (7) When the elongated rotating body having a circular cross section is arranged so as to close the opening along the leading edge of the wind turbine blade from the inside of the wind turbine blade,
In the portion where the peripheral surface of the rotating body is exposed to the outside from the opening, the leading edge of the wind turbine blade is formed, and insects collide with the peripheral surface exposed to the front of such a rotating body. When dirt is generated, the dirt is scraped off at the edge of the opening with the rotation of the rotating body, thereby cleaning the leading edge of the blade. . (8) Inside the wind turbine blade, a brush that engages with the peripheral surface of the rotating body is provided, and a brush driving mechanism that moves the brush in the longitudinal direction of the rotating body is provided.
